The National Centre for Computing Education: your questions answered

Post Syndicated from Sue Sentance original https://www.raspberrypi.org/blog/ncce-questions-answers/

Last week was a very exciting week for us, with the announcement of the National Centre for Computing Education: funded programmes for computing teachers and students for the next four years, to really support the growth and profile of our subject. For me and many others involved in this field over the last decade, it’s an amazing opportunity to have this level of financial support for Computing — something we could previously only dream of. Everybody at Raspberry Pi is very excited about being involved in this important work!

Some background

A new Computing curriculum was introduced in England in September 2014, and it comprises three strands: computer science, information technology, and digital literacy. The latter two have been taught in schools for many years, but the computer science strand had not been taught in schools to the pre-16 age group since the 1980s.

Two Royal Society reports have been widely influential. Firstly, the Shut Down or Restart report (2012) instigated the curriculum change. To support teachers implementing the new curriculum, the CAS Network of Excellence received a modest amount of funding from 2013–2018; the network has had a great impact on the field already, but clearly more government input was needed. The second report, After the Reboot (2017), evaluated current computing education in schools in the UK. It highlighted the challenges faced by teachers who felt unprepared to deliver the Computing curriculum, and recommended that significant government funding be provided to support teachers — and this has now happened! The new programme gives us the opportunity to reach all computing teachers, and to make massive improvements to computing education around the country.

What is the National Centre?

The National Centre, together with specific support for GCSE and A-Level Computer Science, is a government-funded programme of training and support for computing education. It will lead to a great education in the subject for every child from the beginning of primary school to the end of secondary school, enabling them to develop the valuable skills they need, whether or not they choose computing-related careers.

Since last week’s announcement, I’ve received lots of questions from teachers and others about exactly what will be happening and who will be doing the work, and I’ve gathered together answers to many of these questions here. Read on to learn more about our plans.

Key Stages 1–3 and non-GCSE Key Stage 4

If you are a primary teacher or a secondary teacher at Key Stage 3 or non-GCSE KS4, delivering Computing, either as a classroom teacher or as a specialist, you will be able to access professional learning opportunities (CPD) and resources in your region. Initially these will be available via partners working with us, and from September 2019, you will be able to access them via 40 Computing Hubs.

You will be able to register for a certificate and work towards it through a range of activities, working with colleagues and in your region. There will also be a range of online courses to support you at your own pace. Some of these are available now, and many more are to be launched over the next two years.

GCSE Computer Science

If you teach GCSE Computer Science, or you’d like to, there is a unique programme just for you. Bursaries will be available to enable you to take a series of face-to-face and online courses that best suit your needs: these will range from courses aimed at the completely new-to-GCSE teacher to advanced courses for more experienced teachers who are aiming to stretch and challenge students and to hone their subject knowledge.

The online courses will be free for everyone, forever. There will be a diagnostic test to help you plan your journey, and a final assessment to measure your success. You’ll be able to sign up for this programme from January.

A Level Computer Science

If you teach A Level Computer Science, or would like to, you will have access to comprehensive resources for students and teachers. There will also be a range of face-to-face events for both students and teachers. These will be starting shortly, so watch out for more news!

It will take a few months for the Computing Hubs and CPD provision to be available at scale, but in the meantime, there is much within our existing networks that computing teachers can engage with right now: CAS hubs and other events, Code Clubs in schools, STEM Learning training, and our online courses are some examples.

Building our team

We also announced last week that we are looking for new team members to implement our part of the work.

Developing resources, courses, and publications

Our role involves developing a comprehensive set of resources, lesson plans, and schemes of work from Key Stages 1–4, drawing on the best of existing materials plus some new ones. We will also develop all the online courses. We need content writers to help us with both of these areas. We are working on producing newsletters, case studies, and other publications about evidence-based practice, and this will also be part of the new team’s work. At the Raspberry Pi Foundation, we will be leading on the A Level Computer Science programme content, so we have opportunities for people with the skills and experience to focus on this area.

Many of these roles are available if you want to work remotely, but more senior jobs will involve regular days in Cambridge. We also have fixed-term, part-time work available. You can find all our current job openings on this page.

Finally, as a team, we want to visit lots of schools to see what you need and listen to your thoughts, so that we can get our work right for you. If you’d like to support us in that, please get in touch by emailing [email protected].

Hubs, face-to-face training, and certification

STEM Learning, one of our two consortium partners, will be commissioning the 40 Hubs, and they will also be responsible for face-to-face training. The Hubs will become centres of excellence for computing, where teachers can find regional support. Existing CAS (Computing At School) communities will be linked to the 40 Hubs, and CAS Hubs will also play a really important part in the new structure. Our other partner, BCS, will be supporting certification, building on the work they have already done with the BCS Certificate in Computer Science Teaching.

You will be able to access everything you need on the website of the National Centre for Computing Education, where you’ll soon be able to learn where to find your Computing Hub or local CAS communities and discover what is happening in your region.

Across the consortium we have teams of people who are deeply committed to computing, to Computing At School (CAS), and to teaching; most have of us recent teaching experience ourselves. Our first priority is to work with teachers collegially to meet your needs and make life easier for you. So follow the National Centre on Twitter, talk to us, and give us your feedback!

Outside England?

This post has been all about teachers in England, but our free online resources will be available to anyone, anywhere in the world. If you want to talk to us about the needs in your country, do get in touch.

A world-class computing education

Post Syndicated from Philip Colligan original https://www.raspberrypi.org/blog/world-class-computing-education/

I am delighted to share some big news today. The Raspberry Pi Foundation is part of a consortium that has secured over £78 million in government funding to make sure every child in every school in England has access to a world-leading computing education.

National Centre for Computing Education

Working with our partners, STEM Learning and the British Computer Society, we will establish a new National Centre for Computing Education, and deliver a comprehensive programme of support for computing teachers in primary and secondary schools. This will include resources, training, research, certification, and more.

All of the online resources and courses will be completely free for anyone to use. Face-to-face training will be available at no cost to teachers in priority schools, and at very low cost to teachers in other schools. We will also provide bursaries to ensure that schools can release teachers to take part in professional development.

An unprecedented level of investment

This level of investment in computing education is unprecedented anywhere in the world. It is a once-in-a-generation opportunity to transform the way we teach computing and computer science.

The announcement follows the Royal Society’s report from last November, which drew attention to the scale of the challenge. The report was quickly followed by a commitment from the Chancellor in last year’s budget statement that the government would invest £100 million in computing education across the UK. Earlier this year, the Department for Education launched a procurement process focused on England, and today’s announcement is the outcome of that process.

The consortium has been tasked with delivering three pieces of work:

  • A National Centre for Computing Education, which will establish a network of Computing Hubs to provide continuing professional development (CPD) and resources for computing teachers in primary and secondary schools and colleges. The Centre will also facilitate strong links with industry.
  • A teacher training programme to upskill existing teachers to teach GCSE Computer Science.
  • A programme to support AS- and A-level Computer Science students and teachers with high-quality resources and CPD.

A powerful coalition

One of the things I am most excited about is the amazing coalition of partners that has come together around the plans. The consortium brings together subject expertise and knowledge, significant experience of creating brilliant learning experiences and resources, and a track record of delivering high-quality professional development for educators. But we can’t do it on our own.

For example, we’re working with the University of Cambridge team that created Isaac Physics to adapt and extend that platform and programme to support teachers and students of Computer Science A Level.

Our friends at Google have provided practical support and a grant of £1 million to help us create free online courses that will help teachers develop the knowledge and skills to teach computing and computer science.

national centre for computing education

We’re working with the Behavioural Insights Team to make it as easy as possible for teachers to get involved with the programme, and with FutureLearn to provide high-quality online courses.

We’ll also be working in partnership with industry, universities, and non-profits, pooling our expertise and resources to provide the support that educators and schools desperately want. That’s not just a vague promise. As part of the bid process, we secured specific commitments from over 60 organisations who pledged to work with us to make our vision a reality.

Get involved

Over the coming weeks we’ll be sharing more about our plans. In the meantime, here’s how you can get involved:

  1. Check out the launch website for the National Centre for Computing Education and register your email for updates.
  2. Spread the word to teachers, school leaders, industry, non-profits, and anyone else you think might be interested. Send them a link to this blog, or share it on social media.
  3. Help us find amazing, talented people who can join the team to bring this all to life.

A message to readers outside England

Improving computing education should be a priority for every education system and every government in the world. This announcement is focused on computing in schools in England because it’s about funding that has come from the government for that purpose.

I am proud that the Raspberry Pi Foundation will be playing its part in transforming computing education in England. But our mission is global, and our commitment is that the resources and online courses we create will be freely available to anyone, anywhere in the world.

If you are a policy maker outside of England and want to talk about how we could collaborate to advance computing education in your country, please get in touch. We’d love to help.

Build your own weather station with our new guide!

Post Syndicated from Richard Hayler original https://www.raspberrypi.org/blog/build-your-own-weather-station/

One of the most common enquiries I receive at Pi Towers is “How can I get my hands on a Raspberry Pi Oracle Weather Station?” Now the answer is: “Why not build your own version using our guide?”

Build Your Own weather station kit assembled

Tadaaaa! The BYO weather station fully assembled.

Our Oracle Weather Station

In 2016 we sent out nearly 1000 Raspberry Pi Oracle Weather Station kits to schools from around the world who had applied to be part of our weather station programme. In the original kit was a special HAT that allows the Pi to collect weather data with a set of sensors.

The original Raspberry Pi Oracle Weather Station HAT – Build Your Own Raspberry Pi weather station

The original Raspberry Pi Oracle Weather Station HAT

We designed the HAT to enable students to create their own weather stations and mount them at their schools. As part of the programme, we also provide an ever-growing range of supporting resources. We’ve seen Oracle Weather Stations in great locations with a huge differences in climate, and they’ve even recorded the effects of a solar eclipse.

Our new BYO weather station guide

We only had a single batch of HATs made, and unfortunately we’ve given nearly* all the Weather Station kits away. Not only are the kits really popular, we also receive lots of questions about how to add extra sensors or how to take more precise measurements of a particular weather phenomenon. So today, to satisfy your demand for a hackable weather station, we’re launching our Build your own weather station guide!

Build Your Own Raspberry Pi weather station

Fun with meteorological experiments!

Our guide suggests the use of many of the sensors from the Oracle Weather Station kit, so can build a station that’s as close as possible to the original. As you know, the Raspberry Pi is incredibly versatile, and we’ve made it easy to hack the design in case you want to use different sensors.

Many other tutorials for Pi-powered weather stations don’t explain how the various sensors work or how to store your data. Ours goes into more detail. It shows you how to put together a breadboard prototype, it describes how to write Python code to take readings in different ways, and it guides you through recording these readings in a database.

Build Your Own Raspberry Pi weather station on a breadboard

There’s also a section on how to make your station weatherproof. And in case you want to move past the breadboard stage, we also help you with that. The guide shows you how to solder together all the components, similar to the original Oracle Weather Station HAT.

Who should try this build

We think this is a great project to tackle at home, at a STEM club, Scout group, or CoderDojo, and we’re sure that many of you will be chomping at the bit to get started. Before you do, please note that we’ve designed the build to be as straight-forward as possible, but it’s still fairly advanced both in terms of electronics and programming. You should read through the whole guide before purchasing any components.

Build Your Own Raspberry Pi weather station – components

The sensors and components we’re suggesting balance cost, accuracy, and easy of use. Depending on what you want to use your station for, you may wish to use different components. Similarly, the final soldered design in the guide may not be the most elegant, but we think it is achievable for someone with modest soldering experience and basic equipment.

You can build a functioning weather station without soldering with our guide, but the build will be more durable if you do solder it. If you’ve never tried soldering before, that’s OK: we have a Getting started with soldering resource plus video tutorial that will walk you through how it works step by step.

Prototyping HAT for Raspberry Pi weather station sensors

For those of you who are more experienced makers, there are plenty of different ways to put the final build together. We always like to hear about alternative builds, so please post your designs in the Weather Station forum.

Our plans for the guide

Our next step is publishing supplementary guides for adding extra functionality to your weather station. We’d love to hear which enhancements you would most like to see! Our current ideas under development include adding a webcam, making a tweeting weather station, adding a light/UV meter, and incorporating a lightning sensor. Let us know which of these is your favourite, or suggest your own amazing ideas in the comments!

*We do have a very small number of kits reserved for interesting projects or locations: a particularly cool experiment, a novel idea for how the Oracle Weather Station could be used, or places with specific weather phenomena. If have such a project in mind, please send a brief outline to [email protected], and we’ll consider how we might be able to help you.

AWS IoT 1-Click – Use Simple Devices to Trigger Lambda Functions

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/aws-iot-1-click-use-simple-devices-to-trigger-lambda-functions/

We announced a preview of AWS IoT 1-Click at AWS re:Invent 2017 and have been refining it ever since, focusing on simplicity and a clean out-of-box experience. Designed to make IoT available and accessible to a broad audience, AWS IoT 1-Click is now generally available, along with new IoT buttons from AWS and AT&T.

I sat down with the dev team a month or two ago to learn about the service so that I could start thinking about my blog post. During the meeting they gave me a pair of IoT buttons and I started to think about some creative ways to put them to use. Here are a few that I came up with:

Help Request – Earlier this month I spent a very pleasant weekend at the HackTillDawn hackathon in Los Angeles. As the participants were hacking away, they occasionally had questions about AWS, machine learning, Amazon SageMaker, and AWS DeepLens. While we had plenty of AWS Solution Architects on hand (decked out in fashionable & distinctive AWS shirts for easy identification), I imagined an IoT button for each team. Pressing the button would alert the SA crew via SMS and direct them to the proper table.

Camera ControlTim Bray and I were in the AWS video studio, prepping for the first episode of Tim’s series on AWS Messaging. Minutes before we opened the Twitch stream I realized that we did not have a clean, unobtrusive way to ask the camera operator to switch to a closeup view. Again, I imagined that a couple of IoT buttons would allow us to make the request.

Remote Dog Treat Dispenser – My dog barks every time a stranger opens the gate in front of our house. While it is great to have confirmation that my Ring doorbell is working, I would like to be able to press a button and dispense a treat so that Luna stops barking!

Homes, offices, factories, schools, vehicles, and health care facilities can all benefit from IoT buttons and other simple IoT devices, all managed using AWS IoT 1-Click.

All About AWS IoT 1-Click
As I said earlier, we have been focusing on simplicity and a clean out-of-box experience. Here’s what that means:

Architects can dream up applications for inexpensive, low-powered devices.

Developers don’t need to write any device-level code. They can make use of pre-built actions, which send email or SMS messages, or write their own custom actions using AWS Lambda functions.

Installers don’t have to install certificates or configure cloud endpoints on newly acquired devices, and don’t have to worry about firmware updates.

Administrators can monitor the overall status and health of each device, and can arrange to receive alerts when a device nears the end of its useful life and needs to be replaced, using a single interface that spans device types and manufacturers.

I’ll show you how easy this is in just a moment. But first, let’s talk about the current set of devices that are supported by AWS IoT 1-Click.

Who’s Got the Button?
We’re launching with support for two types of buttons (both pictured above). Both types of buttons are pre-configured with X.509 certificates, communicate to the cloud over secure connections, and are ready to use.

The AWS IoT Enterprise Button communicates via Wi-Fi. It has a 2000-click lifetime, encrypts outbound data using TLS, and can be configured using BLE and our mobile app. It retails for $19.99 (shipping and handling not included) and can be used in the United States, Europe, and Japan.

The AT&T LTE-M Button communicates via the LTE-M cellular network. It has a 1500-click lifetime, and also encrypts outbound data using TLS. The device and the bundled data plan is available an an introductory price of $29.99 (shipping and handling not included), and can be used in the United States.

We are very interested in working with device manufacturers in order to make even more shapes, sizes, and types of devices (badge readers, asset trackers, motion detectors, and industrial sensors, to name a few) available to our customers. Our team will be happy to tell you about our provisioning tools and our facility for pushing OTA (over the air) updates to large fleets of devices; you can contact them at [email protected].

AWS IoT 1-Click Concepts
I’m eager to show you how to use AWS IoT 1-Click and the buttons, but need to introduce a few concepts first.

Device – A button or other item that can send messages. Each device is uniquely identified by a serial number.

Placement Template – Describes a like-minded collection of devices to be deployed. Specifies the action to be performed and lists the names of custom attributes for each device.

Placement – A device that has been deployed. Referring to placements instead of devices gives you the freedom to replace and upgrade devices with minimal disruption. Each placement can include values for custom attributes such as a location (“Building 8, 3rd Floor, Room 1337”) or a purpose (“Coffee Request Button”).

Action – The AWS Lambda function to invoke when the button is pressed. You can write a function from scratch, or you can make use of a pair of predefined functions that send an email or an SMS message. The actions have access to the attributes; you can, for example, send an SMS message with the text “Urgent need for coffee in Building 8, 3rd Floor, Room 1337.”

Getting Started with AWS IoT 1-Click
Let’s set up an IoT button using the AWS IoT 1-Click Console:

If I didn’t have any buttons I could click Buy devices to get some. But, I do have some, so I click Claim devices to move ahead. I enter the device ID or claim code for my AT&T button and click Claim (I can enter multiple claim codes or device IDs if I want):

The AWS buttons can be claimed using the console or the mobile app; the first step is to use the mobile app to configure the button to use my Wi-Fi:

Then I scan the barcode on the box and click the button to complete the process of claiming the device. Both of my buttons are now visible in the console:

I am now ready to put them to use. I click on Projects, and then Create a project:

I name and describe my project, and click Next to proceed:

Now I define a device template, along with names and default values for the placement attributes. Here’s how I set up a device template (projects can contain several, but I just need one):

The action has two mandatory parameters (phone number and SMS message) built in; I add three more (Building, Room, and Floor) and click Create project:

I’m almost ready to ask for some coffee! The next step is to associate my buttons with this project by creating a placement for each one. I click Create placements to proceed. I name each placement, select the device to associate with it, and then enter values for the attributes that I established for the project. I can also add additional attributes that are peculiar to this placement:

I can inspect my project and see that everything looks good:

I click on the buttons and the SMS messages appear:

I can monitor device activity in the AWS IoT 1-Click Console:

And also in the Lambda Console:

The Lambda function itself is also accessible, and can be used as-is or customized:

As you can see, this is the code that lets me use {{*}}include all of the placement attributes in the message and {{Building}} (for example) to include a specific placement attribute.

Now Available
I’ve barely scratched the surface of this cool new service and I encourage you to give it a try (or a click) yourself. Buy a button or two, build something cool, and let me know all about it!

Pricing is based on the number of enabled devices in your account, measured monthly and pro-rated for partial months. Devices can be enabled or disabled at any time. See the AWS IoT 1-Click Pricing page for more info.

To learn more, visit the AWS IoT 1-Click home page or read the AWS IoT 1-Click documentation.

Puerto Rico’s First Raspberry Pi Educator Workshop

Post Syndicated from Dana Augustin original https://www.raspberrypi.org/blog/puerto-rico-raspberry-pi-workshop/

Earlier this spring, an excited group of STEM educators came together to participate in the first ever Raspberry Pi and Arduino workshop in Puerto Rico.

Their three-day digital making adventure was led by MakerTechPR’s José Rullán and Raspberry Pi Certified Educator Alex Martínez. They ran the event as part of the Robot Makers challenge organized by Yees! and sponsored by Puerto Rico’s Department of Economic Development and Trade to promote entrepreneurial skills within Puerto Rico’s education system.

Over 30 educators attended the workshop, which covered the use of the Raspberry Pi 3 as a computer and digital making resource. The educators received a kit consisting of a Raspberry Pi 3 with an Explorer HAT Pro and an Arduino Uno. At the end of the workshop, the educators were able to keep the kit as a demonstration unit for their classrooms. They were enthusiastic to learn new concepts and immerse themselves in the world of physical computing.

In their first session, the educators were introduced to the Raspberry Pi as an affordable technology for robotic clubs. In their second session, they explored physical computing and the coding languages needed to control the Explorer HAT Pro. They started off coding with Scratch, with which some educators had experience, and ended with controlling the GPIO pins with Python. In the final session, they learned how to develop applications using the powerful combination of Arduino and Raspberry Pi for robotics projects. This gave them a better understanding of how they could engage their students in physical computing.

“The Raspberry Pi ecosystem is the perfect solution in the classroom because to us it is very resourceful and accessible.” – Alex Martínez

Computer science and robotics courses are important for many schools and teachers in Puerto Rico. The simple idea of programming a microcontroller from a $35 computer increases the chances of more students having access to more technology to create things.

Puerto Rico’s education system has faced enormous challenges after Hurricane Maria, including economic collapse and the government’s closure of many schools due to the exodus of families from the island. By attending training like this workshop, educators in Puerto Rico are becoming more experienced in fields like robotics in particular, which are key for 21st-century skills and learning. This, in turn, can lead to more educational opportunities, and hopefully the reopening of more schools on the island.

“We find it imperative that our children be taught STEM disciplines and skills. Our goal is to continue this work of spreading digital making and computer science using the Raspberry Pi around Puerto Rico. We want our children to have the best education possible.” – Alex Martínez

After attending Picademy in 2016, Alex has integrated the Raspberry Pi Foundation’s online resources into his classroom. He has also taught small workshops around the island and in the local Puerto Rican makerspace community. José is an electrical engineer, entrepreneur, educator and hobbyist who enjoys learning to use technology and sharing his knowledge through projects and challenges.

Ransomware Update: Viruses Targeting Business IT Servers

Post Syndicated from Roderick Bauer original https://www.backblaze.com/blog/ransomware-update-viruses-targeting-business-it-servers/

Ransomware warning message on computer

As ransomware attacks have grown in number in recent months, the tactics and attack vectors also have evolved. While the primary method of attack used to be to target individual computer users within organizations with phishing emails and infected attachments, we’re increasingly seeing attacks that target weaknesses in businesses’ IT infrastructure.

How Ransomware Attacks Typically Work

In our previous posts on ransomware, we described the common vehicles used by hackers to infect organizations with ransomware viruses. Most often, downloaders distribute trojan horses through malicious downloads and spam emails. The emails contain a variety of file attachments, which if opened, will download and run one of the many ransomware variants. Once a user’s computer is infected with a malicious downloader, it will retrieve additional malware, which frequently includes crypto-ransomware. After the files have been encrypted, a ransom payment is demanded of the victim in order to decrypt the files.

What’s Changed With the Latest Ransomware Attacks?

In 2016, a customized ransomware strain called SamSam began attacking the servers in primarily health care institutions. SamSam, unlike more conventional ransomware, is not delivered through downloads or phishing emails. Instead, the attackers behind SamSam use tools to identify unpatched servers running Red Hat’s JBoss enterprise products. Once the attackers have successfully gained entry into one of these servers by exploiting vulnerabilities in JBoss, they use other freely available tools and scripts to collect credentials and gather information on networked computers. Then they deploy their ransomware to encrypt files on these systems before demanding a ransom. Gaining entry to an organization through its IT center rather than its endpoints makes this approach scalable and especially unsettling.

SamSam’s methodology is to scour the Internet searching for accessible and vulnerable JBoss application servers, especially ones used by hospitals. It’s not unlike a burglar rattling doorknobs in a neighborhood to find unlocked homes. When SamSam finds an unlocked home (unpatched server), the software infiltrates the system. It is then free to spread across the company’s network by stealing passwords. As it transverses the network and systems, it encrypts files, preventing access until the victims pay the hackers a ransom, typically between $10,000 and $15,000. The low ransom amount has encouraged some victimized organizations to pay the ransom rather than incur the downtime required to wipe and reinitialize their IT systems.

The success of SamSam is due to its effectiveness rather than its sophistication. SamSam can enter and transverse a network without human intervention. Some organizations are learning too late that securing internet-facing services in their data center from attack is just as important as securing endpoints.

The typical steps in a SamSam ransomware attack are:

1
Attackers gain access to vulnerable server
Attackers exploit vulnerable software or weak/stolen credentials.
2
Attack spreads via remote access tools
Attackers harvest credentials, create SOCKS proxies to tunnel traffic, and abuse RDP to install SamSam on more computers in the network.
3
Ransomware payload deployed
Attackers run batch scripts to execute ransomware on compromised machines.
4
Ransomware demand delivered requiring payment to decrypt files
Demand amounts vary from victim to victim. Relatively low ransom amounts appear to be designed to encourage quick payment decisions.

What all the organizations successfully exploited by SamSam have in common is that they were running unpatched servers that made them vulnerable to SamSam. Some organizations had their endpoints and servers backed up, while others did not. Some of those without backups they could use to recover their systems chose to pay the ransom money.

How to Defend Against SamSam and Other Ransomware Attacks

The best way to respond to a ransomware attack is to avoid having one in the first place. If you are attacked, making sure your valuable data is backed up and unreachable by ransomware infection will ensure that your downtime and data loss will be minimal or none if you ever suffer an attack.

In our previous post, How to Recover From Ransomware, we listed the ten ways to protect your organization from ransomware.

  1. Use anti-virus and anti-malware software or other security policies to block known payloads from launching.
  2. Make frequent, comprehensive backups of all important files and isolate them from local and open networks. Cybersecurity professionals view data backup and recovery (74% in a recent survey) by far as the most effective solution to respond to a successful ransomware attack.
  3. Keep offline backups of data stored in locations inaccessible from any potentially infected computer, such as disconnected external storage drives or the cloud, which prevents them from being accessed by the ransomware.
  4. Install the latest security updates issued by software vendors of your OS and applications. Remember to patch early and patch often to close known vulnerabilities in operating systems, server software, browsers, and web plugins.
  5. Consider deploying security software to protect endpoints, email servers, and network systems from infection.
  6. Exercise cyber hygiene, such as using caution when opening email attachments and links.
  7. Segment your networks to keep critical computers isolated and to prevent the spread of malware in case of attack. Turn off unneeded network shares.

Tackling climate change and helping the community

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/fair-haven-weather-station/

In today’s guest post, seventh-grade students Evan Callas, Will Ross, Tyler Fallon, and Kyle Fugate share their story of using the Raspberry Pi Oracle Weather Station in their Innovation Lab class, headed by Raspberry Pi Certified Educator Chris Aviles.

Raspberry Pi Certified Educator Chris Aviles Innovation Lab Oracle Weather Station

United Nations Sustainable Goals

The past couple of weeks in our Innovation Lab class, our teacher, Mr Aviles, has challenged us students to design a project that helps solve one of the United Nations Sustainable Goals. We chose Climate Action. Innovation Lab is a class that gives students the opportunity to learn about where the crossroads of technology, the environment, and entrepreneurship meet. Everyone takes their own paths in innovation and learns about the environment using project-based learning.

Raspberry Pi Oracle Weather Station

For our climate change challenge, we decided to build a Raspberry Pi Oracle Weather Station. Tackling the issues of climate change in a way that helps our community stood out to us because we knew with the help of this weather station we can send the local data to farmers and fishermen in town. Recent changes in climate have been affecting farmers’ crops. Unexpected rain, heat, and other unusual weather patterns can completely destabilize the natural growth of the plants and destroy their crops altogether. The amount of labour output needed by farmers has also significantly increased, forcing farmers to grow more food on less resources. By using our Raspberry Pi Oracle Weather Station to alert local farmers, they can be more prepared and aware of the weather, leading to better crops and safe boating.

Growing teamwork and coding skills

The process of setting up our weather station was fun and simple. Raspberry Pi made the instructions very easy to understand and read, which was very helpful for our team who had little experience in coding or physical computing. We enjoyed working together as a team and were happy to be growing our teamwork skills.

Once we constructed and coded the weather station, we learned that we needed to support the station with PVC pipes. After we completed these steps, we brought the weather station up to the roof of the school and began collecting data. Our information is currently being sent to the Initial State dashboard so that we can share the information with anyone interested. This information will also be recorded and seen by other schools, businesses, and others from around the world who are using the weather station. For example, we can see the weather in countries such as France, Greece and Italy.

Raspberry Pi Certified Educator Chris Aviles Innovation Lab Oracle Weather Station

Raspberry Pi allows us to build these amazing projects that help us to enjoy coding and physical computing in a fun, engaging, and impactful way. We picked climate change because we care about our community and would like to make a substantial contribution to our town, Fair Haven, New Jersey. It is not every day that kids are given these kinds of opportunities, and we are very lucky and grateful to go to a school and learn from a teacher where these opportunities are given to us. Thanks, Mr Aviles!

To see more awesome projects by Mr Avile’s class, you can keep up with him on his blog and follow him on Twitter.

Artefacts in the classroom with Museum in a Box

Museum in a Box bridges the gap between museums and schools by creating a more hands-on approach to conservation education through 3D printing and digital making.

Fantastic collections and where to find them

Large, impressive statues are truly a sight to be seen. Take for example the 2.4m Hoa Hakananai’a at the British Museum. Its tall stature looms over you as you read its plaque to learn of the statue’s journey from Easter Island to the UK under the care of Captain Cook in 1774, and you can’t help but wonder at how it made it here in one piece.

Hoa Hakananai’a Captain Cook British Museum
Hoa Hakananai’a Captain Cook British Museum

But unless you live near a big city where museums are plentiful, you’re unlikely to see the likes of Hoa Hakananai’a in person. Instead, you have to content yourself with online photos or videos of world-famous artefacts.

And that only accounts for the objects that are on display: conservators estimate that only approximately 5 to 10% of museums’ overall collections are actually on show across the globe. The rest is boxed up in storage, inaccessible to the public due to risk of damage, or simply due to lack of space.

Museum in a Box

Museum in a Box aims to “put museum collections and expert knowledge into your hand, wherever you are in the world,” through modern maker practices such as 3D printing and digital making. With the help of the ‘Scan the World’ movement, an “ambitious initiative whose mission is to archive objects of cultural significance using 3D scanning technologies”, the Museum in a Box team has been able to print small, handheld replicas of some of the world’s most recognisable statues and sculptures.

Museum in a Box Raspberry Pi

Each 3D print gets NFC tags so it can initiate audio playback from a Raspberry Pi that sits snugly within the laser-cut housing of a ‘brain box’. Thus the print can talk directly to us through the magic of wireless technology, replacing the dense, dry text of a museum plaque with engaging speech.

Museum in a Box Raspberry Pi

The Museum in a Box team headed by CEO George Oates (featured in the video above) makes use of these 3D-printed figures alongside original artefacts, postcards, and more to bridge the gap between large, crowded, distant museums and local schools. Modeled after the museum handling collections that used to be sent to schools, Museum in a Box is a cheaper, more accessible alternative. Moreover, it not only allows for hands-on learning, but also encourages children to get directly involved by hacking its technology! With NFC technology readily available to the public, students can curate their own collections about their local area, record their own messages, and send their own box-sized museums on to schools in other towns or countries. In this way, Museum in a Box enables students to explore, and expand the reach of, their own histories.

Moving forward

With the technology perfected and interest in the project ever-growing, Museum in a Box has a busy year ahead. Supporting the new ‘Unstacked’ learning initiative, the team will soon be delivering ten boxes to the Smithsonian Libraries. The team has curated two collections specifically for this: an exploration into Asia-Pacific America experiences of migration to the USA throughout the 20th century, and a look into the history of science.

Smithsonian Library Museum in a Box Raspberry Pi

The team will also be making a box for the British Museum to support their Iraq Scheme initiative, and another box will be heading to the V&A to support their See Red programme. While primarily installed in the Lansbury Micro Museum, the box will also take to the road to visit the local Spotlight high school.

Museum in a Box at Raspberry Fields

Lastly, by far the most exciting thing the Museum in a Box team will be doing this year — in our opinion at least — is showcasing at Raspberry Fields! This is our brand-new festival of digital making that’s taking place on 30 June and 1 July 2018 here in Cambridge, UK. Find more information about it and get your ticket here.

American Public Television Embraces the Cloud — And the Future

Post Syndicated from Andy Klein original https://www.backblaze.com/blog/american-public-television-embraces-the-cloud-and-the-future/

American Public Television website

American Public Television was like many organizations that have been around for a while. They were entrenched using an older technology — in their case, tape storage and distribution — that once met their needs but was limiting their productivity and preventing them from effectively collaborating with their many media partners. APT’s VP of Technology knew that he needed to move into the future and embrace cloud storage to keep APT ahead of the game.
Since 1961, American Public Television (APT) has been a leading distributor of groundbreaking, high-quality, top-rated programming to the nation’s public television stations. Gerry Field is the Vice President of Technology at APT and is responsible for delivering their extensive program catalog to 350+ public television stations nationwide.

In the time since Gerry  joined APT in 2007, the industry has been in digital overdrive. During that time APT has continued to acquire and distribute the best in public television programming to their technically diverse subscribers.

This created two challenges for Gerry. First, new technology and format proliferation were driving dramatic increases in digital storage. Second, many of APT’s subscribers struggled to keep up with the rapidly changing industry. While some subscribers had state-of-the-art satellite systems to receive programming, others had to wait for the post office to drop off programs recorded on tape weeks earlier. With no slowdown on the horizon of innovation in the industry, Gerry knew that his storage and distribution systems would reach a crossroads in no time at all.

American Public Television logo

Living the tape paradigm

The digital media industry is only a few years removed from its film, and later videotape, roots. Tape was the input and the output of the industry for many years. As a consequence, the tools and workflows used by the industry were built and designed to work with tape. Over time, the “file” slowly replaced the tape as the object to be captured, edited, stored and distributed. Trouble was, many of the systems and more importantly workflows were based on processing tape, and these have proven to be hard to change.

At APT, Gerry realized the limits of the tape paradigm and began looking for technologies and solutions that enabled workflows based on file and object based storage and distribution.

Thinking file based storage and distribution

For data (digital media) storage, APT, like everyone else, started by installing onsite storage servers. As the amount of digital data grew, more storage was added. In addition, APT was expanding its distribution footprint by creating or partnering with distribution channels such as CreateTV and APT Worldwide. This dramatically increased the number of programming formats and the amount of data that had to be stored. As a consequence, updating, maintaining, and managing the APT storage systems was becoming a major challenge and a major resource hog.

APT Online

Knowing that his in-house storage system was only going to cost more time and money, Gerry decided it was time to look at cloud storage. But that wasn’t the only reason he looked at the cloud. While most people consider cloud storage as just a place to back up and archive files, Gerry was envisioning how the ubiquity of the cloud could help solve his distribution challenges. The trouble was the price of cloud storage from vendors like Amazon S3 and Microsoft Azure was a non-starter, especially for a non-profit. Then Gerry came across Backblaze. B2 Cloud Storage service met all of his performance requirements, and at $0.005/GB/month for storage and $0.01/GB for downloads it was nearly 75% less than S3 or Azure.

Gerry did the math and found that he could economically incorporate B2 Cloud Storage into his IT portfolio, using it for both program submission and for active storage and archiving of the APT programs. In addition, B2 now gives him the foundation necessary to receive and distribute programming content over the Internet. This is especially useful for organizations that can’t conveniently access satellite distribution systems. Not to mention downloading from the cloud is much faster than sending a tape through the mail.

Adding B2 Cloud Storage to their infrastructure has helped American Public Television address two key challenges. First, they now have “unlimited” storage in the cloud without having to add any hardware. In addition, with B2, they only pay for the storage they use. That means they don’t have to buy storage upfront trying to match the maximum amount of storage they’ll ever need. Second, by using B2 as a distribution source for their programming APT subscribers, especially the smaller and remote ones, can get content faster and more reliably without having to perform costly upgrades to their infrastructure.

The road ahead

As APT gets used to their file based infrastructure and workflow, there are a number of cost saving and income generating ideas they are pondering which are now worth considering. Here are a few:

Program Submissions — New content can be uploaded from anywhere using a web browser, an Internet connection, and a login. For example, a producer in Cambodia can upload their film to B2. From there the film is downloaded to an in-house system where it is processed and transcoded using compute. The finished film is added to the APT catalog and added to B2. Once there, the program is instantly available for subscribers to order and download.

“The affordability and performance of Backblaze B2 is what allowed us to make the B2 cloud part of the APT data storage and distribution strategy into the future.” — Gerry Field

Easier Previews — At any time, work in process or finished programs can be made available for download from the B2 cloud. One place this could be useful is where a subscriber needs to review a program to comply with local policies and practices before airing. In the old system, each “one-off” was a time consuming manual process.

Instant Subscriptions — There are many organizations such as schools and businesses that want to use just one episode of a desired show. With an e-commerce based website, current or even archived programming kept in B2 could be available to download or stream for a minimal charge.

At APT there were multiple technologies needed to make their file-based infrastructure work, but as Gerry notes, having an affordable, trustworthy, cloud storage service like B2 is one of the critical building blocks needed to make everything work together.

Friday Squid Blogging: Giant Squid Stealing Food from Each Other

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/03/friday_squid_bl_617.html

An interesting hunting strategy:

Off of northern Spain, giant squid often feed on schools of fish called blue whiting. The schools swim 400 meters or less below the surface, while the squid prefer to hang out around a mile deep. The squid must ascend to hunt, probably seizing fish from below with their tentacles, then descend again. In this scenario, a squid could save energy by pirating food from its neighbor rather than hunting its own fish, Guerra says: If the target squid has already carried its prey back to the depths to eat, the pirate could save itself a trip up to the shallow water. Staying below would also protect a pirate from predators such as dolphins and sperm whales that hang around the fish schools.

If a pirate happened to kill its victim, it would also reduce competition. The scientists think that’s what happened with the Bares squid: Its tentacles were ripped off in the fight over food. “The victim, disoriented and wounded, could enter a warmer mass of water in which the efficiency of their blood decreases markedly,” the authors write in a recent paper in the journal Ecology. “In this way, the victim, almost asphyxiated, would be at the mercy of the marine currents, being dragged toward the coast.”

It’s called “food piracy.”

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Our 2017 Annual Review

Post Syndicated from Oliver Quinlan original https://www.raspberrypi.org/blog/annual-review-2017/

Each year we take stock at the Raspberry Pi Foundation, looking back at what we’ve achieved over the previous twelve months. We’ve just published our Annual Review for 2017, reflecting on the progress we’ve made as a foundation and a community towards putting the power of digital making in the hands of people all over the world.

In the review, you can find out about all the different education programmes we run. Moreover, you can hear from people who have taken part, learned through making, and discovered they can do things with technology that they never thought they could.

Growing our reach

Our reach grew hugely in 2017, and the numbers tell this story.

By the end of 2017, we’d sold over 17 million Raspberry Pi computers, bringing tools for learning programming and physical computing to people all over the world.

Vibrant learning and making communities

Code Club grew by 2964 clubs in 2017, to over 10000 clubs across the world reaching over 150000 9- to 13-year-olds.

“The best moment is seeing a child discover something for the first time. It is amazing.”
– Code Club volunteer

In 2017 CoderDojo became part of the Raspberry Pi family. Over the year, it grew by 41% to 1556 active Dojos, involving nearly 40000 7- to 17-year-olds in creating with code and collaborating to learn about technology.

Raspberry Jams continued to grow, with 18700 people attending events organised by our amazing community members.



Supporting teaching and learning

We reached 208 projects in our online resources in 2017, and 8.5 million people visited these to get making.

“I like coding because it’s like a whole other language that you have to learn, and it creates something very interesting in the end.”
– Betty, Year 10 student

2017 was also the year we began offering online training courses. 19000 people joined us to learn about programming, physical computing, and running a Code Club.



Over 6800 young people entered Mission Zero and Mission Space Lab, 2017’s two Astro Pi challenges. They created code that ran on board the International Space Station or will run soon.

More than 600 educators joined our face-to-face Picademy training last year. Our community of Raspberry Pi Certified Educators grew to 1500, all leading digital making across schools, libraries, and other settings where young people learn.

Being social

Well over a million people follow us on social media, and in 2017 we’ve seen big increases in our YouTube and Instagram followings. We have been creating much more video content to share what we do with audiences on these and other social networks.

The future

It’s been a big year, as we continue to reach even more people. This wouldn’t be possible without the amazing work of volunteers and community members who do so much to create opportunities for others to get involved. Behind each of these numbers is a person discovering digital making for the first time, learning new skills, or succeeding with a project that makes a difference to something they care about.

Raspberry Pi 3 Model B+ on sale now at $35

Post Syndicated from Eben Upton original https://www.raspberrypi.org/blog/raspberry-pi-3-model-bplus-sale-now-35/

Here’s a long post. We think you’ll find it interesting. If you don’t have time to read it all, we recommend you watch this video, which will fill you in with everything you need, and then head straight to the product page to fill yer boots. (We recommend the video anyway, even if you do have time for a long read. ‘Cos it’s fab.)

A BRAND-NEW PI FOR π DAY

Raspberry Pi 3 Model B+ is now on sale now for $35, featuring: – A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU – Dual-band 802.11ac wireless LAN and Bluetooth 4.2 – Faster Ethernet (Gigabit Ethernet over USB 2.0) – Power-over-Ethernet support (with separate PoE HAT) – Improved PXE network and USB mass-storage booting – Improved thermal management Alongside a 200MHz increase in peak CPU clock frequency, we have roughly three times the wired and wireless network throughput, and the ability to sustain high performance for much longer periods.

If you’ve been a Raspberry Pi watcher for a while now, you’ll have a bit of a feel for how we update our products. Just over two years ago, we released Raspberry Pi 3 Model B. This was our first 64-bit product, and our first product to feature integrated wireless connectivity. Since then, we’ve sold over nine million Raspberry Pi 3 units (we’ve sold 19 million Raspberry Pis in total), which have been put to work in schools, homes, offices and factories all over the globe.

Those Raspberry Pi watchers will know that we have a history of releasing improved versions of our products a couple of years into their lives. The first example was Raspberry Pi 1 Model B+, which added two additional USB ports, introduced our current form factor, and rolled up a variety of other feedback from the community. Raspberry Pi 2 didn’t get this treatment, of course, as it was superseded after only one year; but it feels like it’s high time that Raspberry Pi 3 received the “plus” treatment.

So, without further ado, Raspberry Pi 3 Model B+ is now on sale for $35 (the same price as the existing Raspberry Pi 3 Model B), featuring:

  • A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
  • Dual-band 802.11ac wireless LAN and Bluetooth 4.2
  • Faster Ethernet (Gigabit Ethernet over USB 2.0)
  • Power-over-Ethernet support (with separate PoE HAT)
  • Improved PXE network and USB mass-storage booting
  • Improved thermal management

Alongside a 200MHz increase in peak CPU clock frequency, we have roughly three times the wired and wireless network throughput, and the ability to sustain high performance for much longer periods.

Behold the shiny

Raspberry Pi 3B+ is available to buy today from our network of Approved Resellers.

New features, new chips

Roger Thornton did the design work on this revision of the Raspberry Pi. Here, he and I have a chat about what’s new.

Introducing the Raspberry Pi 3 Model B+

Raspberry Pi 3 Model B+ is now on sale now for $35, featuring: – A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU – Dual-band 802.11ac wireless LAN and Bluetooth 4.2 – Faster Ethernet (Gigabit Ethernet over USB 2.0) – Power-over-Ethernet support (with separate PoE HAT) – Improved PXE network and USB mass-storage booting – Improved thermal management Alongside a 200MHz increase in peak CPU clock frequency, we have roughly three times the wired and wireless network throughput, and the ability to sustain high performance for much longer periods.

The new product is built around BCM2837B0, an updated version of the 64-bit Broadcom application processor used in Raspberry Pi 3B, which incorporates power integrity optimisations, and a heat spreader (that’s the shiny metal bit you can see in the photos). Together these allow us to reach higher clock frequencies (or to run at lower voltages to reduce power consumption), and to more accurately monitor and control the temperature of the chip.

Dual-band wireless LAN and Bluetooth are provided by the Cypress CYW43455 “combo” chip, connected to a Proant PCB antenna similar to the one used on Raspberry Pi Zero W. Compared to its predecessor, Raspberry Pi 3B+ delivers somewhat better performance in the 2.4GHz band, and far better performance in the 5GHz band, as demonstrated by these iperf results from LibreELEC developer Milhouse.

Tx bandwidth (Mb/s) Rx bandwidth (Mb/s)
Raspberry Pi 3B 35.7 35.6
Raspberry Pi 3B+ (2.4GHz) 46.7 46.3
Raspberry Pi 3B+ (5GHz) 102 102

The wireless circuitry is encapsulated under a metal shield, rather fetchingly embossed with our logo. This has allowed us to certify the entire board as a radio module under FCC rules, which in turn will significantly reduce the cost of conformance testing Raspberry Pi-based products.

We’ll be teaching metalwork next.

Previous Raspberry Pi devices have used the LAN951x family of chips, which combine a USB hub and 10/100 Ethernet controller. For Raspberry Pi 3B+, Microchip have supported us with an upgraded version, LAN7515, which supports Gigabit Ethernet. While the USB 2.0 connection to the application processor limits the available bandwidth, we still see roughly a threefold increase in throughput compared to Raspberry Pi 3B. Again, here are some typical iperf results.

Tx bandwidth (Mb/s) Rx bandwidth (Mb/s)
Raspberry Pi 3B 94.1 95.5
Raspberry Pi 3B+ 315 315

We use a magjack that supports Power over Ethernet (PoE), and bring the relevant signals to a new 4-pin header. We will shortly launch a PoE HAT which can generate the 5V necessary to power the Raspberry Pi from the 48V PoE supply.

There… are… four… pins!

Coming soon to a Raspberry Pi 3B+ near you

Raspberry Pi 3B was our first product to support PXE Ethernet boot. Testing it in the wild shook out a number of compatibility issues with particular switches and traffic environments. Gordon has rolled up fixes for all known issues into the BCM2837B0 boot ROM, and PXE boot is now enabled by default.

Clocking, voltages and thermals

The improved power integrity of the BCM2837B0 package, and the improved regulation accuracy of our new MaxLinear MxL7704 power management IC, have allowed us to tune our clocking and voltage rules for both better peak performance and longer-duration sustained performance.

Below 70°C, we use the improvements to increase the core frequency to 1.4GHz. Above 70°C, we drop to 1.2GHz, and use the improvements to decrease the core voltage, increasing the period of time before we reach our 80°C thermal throttle; the reduction in power consumption is such that many use cases will never reach the throttle. Like a modern smartphone, we treat the thermal mass of the device as a resource, to be spent carefully with the goal of optimising user experience.

This graph, courtesy of Gareth Halfacree, demonstrates that Raspberry Pi 3B+ runs faster and at a lower temperature for the duration of an eight‑minute quad‑core Sysbench CPU test.

Note that Raspberry Pi 3B+ does consume substantially more power than its predecessor. We strongly encourage you to use a high-quality 2.5A power supply, such as the official Raspberry Pi Universal Power Supply.

FAQs

We’ll keep updating this list over the next couple of days, but here are a few to get you started.

Are you discontinuing earlier Raspberry Pi models?

No. We have a lot of industrial customers who will want to stick with the existing products for the time being. We’ll keep building these models for as long as there’s demand. Raspberry Pi 1B+, Raspberry Pi 2B, and Raspberry Pi 3B will continue to sell for $25, $35, and $35 respectively.

What about Model A+?

Raspberry Pi 1A+ continues to be the $20 entry-level “big” Raspberry Pi for the time being. We are considering the possibility of producing a Raspberry Pi 3A+ in due course.

What about the Compute Module?

CM1, CM3 and CM3L will continue to be available. We may offer versions of CM3 and CM3L with BCM2837B0 in due course, depending on customer demand.

Are you still using VideoCore?

Yes. VideoCore IV 3D is the only publicly-documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less.

Credits

A project like this requires a vast amount of focused work from a large team over an extended period. Particular credit is due to Roger Thornton, who designed the board and ran the exhaustive (and exhausting) RF compliance campaign, and to the team at the Sony UK Technology Centre in Pencoed, South Wales. A partial list of others who made major direct contributions to the BCM2837B0 chip program, CYW43455 integration, LAN7515 and MxL7704 developments, and Raspberry Pi 3B+ itself follows:

Transition from Scratch to Python with FutureLearn

Post Syndicated from Dan Fisher original https://www.raspberrypi.org/blog/futurelearn-scratch-to-python/

With the launch of our first new free online course of 2018 — Scratch to Python: Moving from Block- to Text-based Programming — two weeks away, I thought this would be a great opportunity to introduce you to the ins and outs of the course content so you know what to expect.

FutureLearn: Moving from Scratch to Python

Learn how to apply the thinking and programming skills you’ve learnt in Scratch to text-based programming languages like Python.

Take the plunge into text-based programming

The idea for this course arose from our conversations with educators who had set up a Code Club in their schools. Most people start a club by teaching Scratch, a block-based programming language, because it allows learners to drag and drop blocks of pre-written code into a window to create a program. The blocks automatically snap together, making it easy to build fun and educational projects that don’t require much troubleshooting. You can do almost anything a beginner could wish for with Scratch, even physical computing to control LEDs, buzzers, buttons, motors, and more!

Scratch to Python FutureLearn Raspberry Pi

However, on our face-to-face training programme Picademy, educators told us that they were finding it hard to engage children who had outgrown Scratch and needed a new challenge. It was easy for me to imagine: a young learner, who once felt confident about programming using Scratch, is now confused by the alien, seemingly awkward interface of Python. What used to take them minutes in Scratch now takes them hours to code, and they start to lose interest — not a good result, I’m sure you’ll agree. I wanted to help educators to navigate this period in their learners’ development, and so I’ve written a course that shows you how to take the programming and thinking skills you and your learners have developed in Scratch, and apply them to Python.

Scratch to Python FutureLearn Raspberry Pi

Who is the course for?

Educators from all backgrounds who are working with secondary school-aged learners. It will also be interesting to anyone who has spent time working with Scratch and wants to understand how programming concepts translate between different languages.

“It was great fun, and I thought that the ideas and resources would be great to use with Year 7 classes.”
Sue Grey, Classroom Teacher

What is covered?

After showing you the similarities and differences of Scratch and Python, and how the skills learned using one can be applied to the other, we will look at turning more complex Scratch scripts into Python programs. Through creating a Mad Libs game and developing a username generator, you will see how programs can be simplified in a text-based language. We will give you our top tips for debugging Python code, and you’ll have the chance to share your ideas for introducing more complex programs to your students.

Scratch to Python FutureLearn Raspberry Pi

After that, we will look at different data types in Python and write a script to calculate how old you are in dog years. Finally, you’ll dive deeper into the possibilities of Python by installing and using external Python libraries to perform some amazing tasks.

By the end of the course, you’ll be able to:

  • Transfer programming and thinking skills from Scratch to Python
  • Use fundamental Python programming skills
  • Identify errors in your Python code based on error messages, and debug your scripts
  • Produce tools to support students’ transition from block-based to text-based programming
  • Understand the power of text-based programming and what you can create with it

Where can I sign up?

The free four-week course starts on 12 March 2018, and you can sign up now on FutureLearn. While you’re there, be sure to check out our other free courses, such as Prepare to Run a Code Club, Teaching Physical Computing with a Raspberry Pi and Python, and our second new course Build a Makerspace for Young People — more information on it will follow in tomorrow’s blog post.

Raspberry Crusoe: how a Pi got lost at sea

Post Syndicated from James Robinson original https://www.raspberrypi.org/blog/lost-high-altitude-balloon/

The tale of the little HAB that could and its three-month journey from Portslade Aldridge Community Academy in the UK to the coast of Denmark.

PACA Computing on Twitter

Where did it land ???? #skypaca #skycademy @pacauk #RaspberryPi

High-altitude ballooning

Some of you may be familiar with Raspberry Pi being used as the flight computer, or tracker, of high-altitude balloon (HAB) payloads. For those who aren’t, high-altitude ballooning is a relatively simple activity (at least in principle) where a tracker is attached to a large weather balloon which is then released into the atmosphere. While the HAB ascends, the tracker takes pictures and data readings the whole time. Eventually (around 30km up) the balloon bursts, leaving the payload free to descend and be recovered. For a better explanation, I’m handing over to the students of UTC Oxfordshire:

Pi in the Sky | UTC Oxfordshire

On Tuesday 2nd May, students launched a Raspberry Pi computer 35,000 metres into the stratosphere as part of an Employer-Led project at UTC Oxfordshire, set by the Raspberry Pi Foundation. The project involved engineering, scientific and communication/publicity skills being developed to create the payload and code to interpret experiments set by the science team.

Skycademy

Over the past few years, we’ve seen schools and their students explore the possibilities that high-altitude ballooning offers, and back in 2015 and 2016 we ran Skycademy. The programme was simple enough: get a bunch of educators together in the same space, show them how to launch a balloon flight, and then send them back to their students to try and repeat what they’ve learned. Since the first Skycademy event, a number of participants have carried out launches, and we are extremely proud of each and every one of them.

The case of the vanishing PACA HAB

Not every launch has been a 100% success though. There are many things that can and do go wrong during HAB flights, and watching each launch from the comfort of our office can be a nerve-wracking experience. We had such an experience back in July 2017, during the launch performed by Skycademy graduate and Raspberry Pi Certified Educator Dave Hartley and his students from Portslade Aldridge Community Academy (PACA).

Dave and his team had been working on their payload for some time, and were awaiting suitable weather conditions. Early one Wednesday in July, everything aligned: they had a narrow window of good weather and so set their launch plan in motion. Soon they had assembled the payload in the school grounds and all was ready for the launch.

Dave Hartley on Twitter

Launch day! @pacauk #skycademy #skypaca #raspberrypi

Just before 11:00, they’d completed their final checks and released their payload into the atmosphere. Over the course of 64 minutes, the HAB steadily rose to an altitude of 25647m, where it captured some amazing pictures before the balloon burst and a rapid descent began.

Portslade Aldridge Community Academy Skycademy Raspberry Pi
Portslade Aldridge Community Academy Skycademy Raspberry Pi

Soon after the payload began to descend, the team noticed something worrying: their predicted descent path took the payload dangerously far south — it was threatening to land in the sea. As the payload continued to lose altitude, their calculated results kept shifting, alternately predicting a landing on the ground or out to sea. Eventually it became clear that the payload would narrowly overshoot the land, and it finally landed about 2 km out to sea.

Portslade Aldridge Community Academy Skycademy Raspberry Pi High Altitude Ballooning

The path of the balloon

It’s not uncommon for a HAB payload to get lost. There are many ways this can happen, particularly in a narrow country with a prevailing easterly wind like the UK. Payloads can get lost at sea, land somewhere inaccessible, or simply run out of power before they are located and retrieved. So normally, this would be the end of the story for the PACA students — even if the team had had a speedboat to hand, their payload was surely lost for good.

A message from Denmark

However, this is not the end of our story! A couple of months later, I arrived at work and saw this tweet from a colleague:

Raspberry Pi on Twitter

Anyone lost a Raspberry Pi HAB? Someone found this one on a beach in south western Denmark yesterday #UKHAS https://t.co/7lBzFiemgr

Good Samaritan Henning Hansen had found a Raspberry Pi washed up on a remote beach in Denmark! While walking a stretch of coast to collect plastic debris for an environmental monitoring project, he came across something unusual near the shore at 55°04’53.0″N and 8°38’46.9″E.

This of course piqued my interest, and we began to investigate the image he had shared on Facebook.

Portslade Aldridge Community Academy Skycademy Raspberry Pi High Altitude Ballooning

Inspecting the photo closely, we noticed a small asset label — the kind of label that, over a year earlier, we’d stuck to each and every bit of Skycademy field kit. We excitedly claimed the kit on behalf of Dave and his students, and contacted Henning to arrange the recovery of the payload. He told us it must have been carried ashore with the tide some time between 21 and 27 September, and probably on 21 September, since that day had the highest tide over the period. This meant the payload must have spent over two months at sea!

From the photo we could tell that the Raspberry Pi had suffered significant corrosion, having been exposed to salt water for so long, and so we felt pessimistic about the chances that there would be any recoverable data on it. However, Henning said that he’d been able to read some files from the FAT partition of the SD card, so all hope was not lost.

After a few weeks and a number of complications around dispatch and delivery (thank you, Henning, for your infinite patience!), Helen collected the HAB from a local Post Office.

Portslade Aldridge Community Academy Skycademy Raspberry Pi High Altitude Ballooning

SUCCESS!

We set about trying to read the data from the SD card, and eventually became disheartened: despite several attempts, we were unable to read its contents.

In a last-ditch effort, we gave the SD card to Jonathan, one of our engineers, who initially laughed at the prospect of recovering any data from it. But ten minutes later, he returned with news of success!

Since then, we’ve been able to reunite the payload with the PACA launch team, and the students sent us the perfect message to end this story:

2017 Weather Station round-up

Post Syndicated from Richard Hayler original https://www.raspberrypi.org/blog/2017-weather-station/

As we head into 2018 and start looking forward to longer days in the Northern hemisphere, I thought I’d take a look back at last year’s weather using data from Raspberry Pi Oracle Weather Stations. One of the great things about the kit is that as well as uploading all its readings to the shared online Oracle database, it stores them locally on the Pi in a MySQL or MariaDB database. This means you can use the power of SQL queries coupled with Python code to do automatic data analysis.

Soggy Surrey

My Weather Station has only been installed since May, so I didn’t have a full 52 weeks of my own data to investigate. Still, my station recorded more than 70000 measurements. Living in England, the first thing I wanted to know was: which was the wettest month? Unsurprisingly, both in terms of average daily rainfall and total rainfall, the start of the summer period — exactly when I went on a staycation — was the soggiest:

What about the global Weather Station community?

Even soggier Bavaria

Here things get slightly trickier. Although we have a shiny Oracle database full of all participating schools’ sensor readings, some of the data needs careful interpretation. Many kits are used as part of the school curriculum and do not always record genuine outdoor conditions. Nevertheless, it appears that Adalbert Stifter Gymnasium in Bavaria, Germany, had an even wetter 2017 than my home did:

Where the wind blows

The records Robert-Dannemann Schule in Westerstede, Germany, is a good example of data which was most likely collected while testing and investigating the weather station sensors, rather than in genuine external conditions. Unless this school’s Weather Station was transported to a planet which suffers from extreme hurricanes, it wasn’t actually subjected to wind speeds above 1000km/h in November. Dismissing these and all similarly suspect records, I decided to award the ‘Windiest location of the year’ prize to CEIP Noalla-Telleiro, Spain.


View larger map

This school is right on the coast, and is subject to some strong and squally weather systems.

Weather Station at CEIP Noalla - Telleiro

Weather Station at CEIP Noalla-Telleiro

They’ve mounted their wind vane and anemometer nice and high, so I can see how they were able to record such high wind velocities.

A couple of Weather Stations have recently been commissioned in equally exposed places — it will be interesting to see whether they will record even higher speeds during 2018.

Highs and lows

After careful analysis and a few disqualifications (a couple of Weather Stations in contention for this category were housed indoors), the ‘Hottest location’ award went to High School of Chalastra in Thessaloniki, Greece. There were a couple of Weather Stations (the one at The Marwadi Education Foundation in India, for example) that reported higher average temperatures than Chalastra’s 24.54 ºC. However, they had uploaded far fewer readings and their data coverage of 2017 was only partial.


View larger map

At the other end of the thermometer, the location with the coldest average temperature is École de la Rose Sauvage in Calgary, Canada, with a very chilly 9.9 ºC.

Ecole de la Rose sauvage Weather Station

Weather Station at École de la Rose Sauvage

I suspect this school has a good chance of retaining the title: their lowest 2017 temperature of -24 ºC is likely to be beaten in 2018 due to extreme weather currently bringing a freezing start to the year in that part of the world.

Analyse your own Weather Station data

If you have an Oracle Raspberry Pi Weather Station and would like to perform an annual review of your local data, you can use this Python script as a starting point. It will display a monthly summary of the temperature and rainfall for 2017, and you should be able to customise the code to focus on other sensor data or on a particular time of year. We’d love to see your results, so please share your findings with [email protected], and we’ll send you some limited-edition Weather Station stickers.

Zero WH: pre-soldered headers and what to do with them

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/zero-wh/

If you head over to the website of your favourite Raspberry Pi Approved Reseller today, you may find the new Zero WH available to purchase. But what it is? Why is it different, and what can you do with it?

Raspberry Pi Zero WH

“If you like pre-soldered headers, and getting caught in the rain…”

Raspberry Pi Zero WH

Imagine a Raspberry Pi Zero W. Now add a professionally soldered header. Boom, that’s the Raspberry Pi Zero WH! It’s your same great-tasting Pi, with a brand-new…crust? It’s perfect for everyone who doesn’t own a soldering iron or who wants the soldering legwork done for them.

What you can do with the Zero WH

What can’t you do? Am I right?! The small size of the Zero W makes it perfect for projects with minimal wiggle-room. In such projects, some people have no need for GPIO pins — they simply solder directly to the board. However, there are many instances where you do want a header on your Zero W, for example in order to easily take advantage of the GPIO expander tool for Debian Stretch on a PC or Mac.

GPIO expander in clubs and classrooms

As Ben Nuttall explains in his blog post on the topic:

[The GPIO expander tool] is a real game-changer for Raspberry Jams, Code Clubs, CoderDojos, and schools. You can live boot the Raspberry Pi Desktop OS from a USB stick, use Linux PCs, or even install [the Pi OS] on old computers. Then you have really simple access to physical computing without full Raspberry Pi setups, and with no SD cards to configure.

Using the GPIO expander with the Raspberry Pi Zero WH decreases the setup cost for anyone interested in trying out physical computing in the classroom or at home. (And once you’ve stuck your toes in, you’ll obviously fall in love and will soon find yourself with multiple Raspberry Pi models, HATs aplenty, and an area in your home dedicated to your new adventure in Raspberry Pi. Don’t say I didn’t warn you.)

Other uses for a Zero W with a header

The GPIO expander setup is just one of a multitude of uses for a Raspberry Pi Zero W with a header. You may want the header for prototyping before you commit to soldering wires directly to a board. Or you may have a temporary build in mind for your Zero W, in which case you won’t want to commit to soldering wires to the board at all.

Raspberry Pi Zero WH

Your use case may be something else entirely — tell us in the comments below how you’d utilise a pre-soldered Raspberry Pi Zero WH in your project. The best project idea will receive ten imaginary house points of absolutely no practical use, but immense emotional value. Decide amongst yourselves who you believe should win them — I’m going to go waste a few more hours playing SLUG!

Playing tic-tac-toe against a Raspberry Pi at Maker Faire

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/tic-tac-toe-maker-faire/

At Maker Faire New York, we met up with student Toby Goebeler of Dover High School, Pennsylvania, to learn more about his Tic-Tac-Toe Robot.

Tic-tac-toe with Dover Robotics

We came to see Toby and Brian Bahn, physics teacher for Dover High School and leader of the Dover Robotics club, so they could tell us about the inner workings of the Tic-Tac-Toe Robot project, and how the Raspberry Pi fit within it. Check out our video for Toby’s explanation of the build and the software controlling it.

Wooden robotic arm — Toby Goebeler Tic-Tac-Toe arm Raspberry Pi

Toby’s original robotic arm prototype used a weight to direct the pen on and off the paper. He later replaced this with a servo motor.

Toby documented the prototyping process for the robot on the Dover Robotics blog. Head over there to hear more about the highs and lows of building a robotic arm from scratch, and about how Toby learned to integrate a Raspberry Pi for both software and hardware control.

The finished build is a tic-tac-toe beast, besting everyone who dares to challenge it to a game.

And in case you’re wondering: no, none of the Raspberry Pi team were able to beat the Tic-Tac-Toe Robot when we played against it.

Your turn

We always love seeing Raspberry Pis being used in schools to teach coding and digital making, whether in the classroom or during after-school activities such as the Dover Robotics club and our own Code Clubs and CoderDojos. If you are part of a coding or robotics club, we’d love to hear your story! So make sure to share your experiences and projects in the comments below, or via our social media accounts.

Thank you for my new Raspberry Pi, Santa! What next?

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/thank-you-for-my-new-raspberry-pi-santa-what-next/

Note: the Pi Towers team have peeled away from their desks to spend time with their families over the festive season, and this blog will be quiet for a while as a result. We’ll be back in the New Year with a bushel of amazing projects, awesome resources, and much merriment and fun times. Happy holidays to all!

Now back to the matter at hand. Your brand new Christmas Raspberry Pi.

Your new Raspberry Pi

Did you wake up this morning to find a new Raspberry Pi under the tree? Congratulations, and welcome to the Raspberry Pi community! You’re one of us now, and we’re happy to have you on board.

But what if you’ve never seen a Raspberry Pi before? What are you supposed to do with it? What’s all the fuss about, and why does your new computer look so naked?

Setting up your Raspberry Pi

Are you comfy? Good. Then let us begin.

Download our free operating system

First of all, you need to make sure you have an operating system on your micro SD card: we suggest Raspbian, the Raspberry Pi Foundation’s official supported operating system. If your Pi is part of a starter kit, you might find that it comes with a micro SD card that already has Raspbian preinstalled. If not, you can download Raspbian for free from our website.

An easy way to get Raspbian onto your SD card is to use a free tool called Etcher. Watch The MagPi’s Lucy Hattersley show you what you need to do. You can also use NOOBS to install Raspbian on your SD card, and our Getting Started guide explains how to do that.

Plug it in and turn it on

Your new Raspberry Pi 3 comes with four USB ports and an HDMI port. These allow you to plug in a keyboard, a mouse, and a television or monitor. If you have a Raspberry Pi Zero, you may need adapters to connect your devices to its micro USB and micro HDMI ports. Both the Raspberry Pi 3 and the Raspberry Pi Zero W have onboard wireless LAN, so you can connect to your home network, and you can also plug an Ethernet cable into the Pi 3.

Make sure to plug the power cable in last. There’s no ‘on’ switch, so your Pi will turn on as soon as you connect the power. Raspberry Pi uses a micro USB power supply, so you can use a phone charger if you didn’t receive one as part of a kit.

Learn with our free projects

If you’ve never used a Raspberry Pi before, or you’re new to the world of coding, the best place to start is our projects site. It’s packed with free projects that will guide you through the basics of coding and digital making. You can create projects right on your screen using Scratch and Python, connect a speaker to make music with Sonic Pi, and upgrade your skills to physical making using items from around your house.

Here’s James to show you how to build a whoopee cushion using a Raspberry Pi, paper plates, tin foil and a sponge:

Whoopee cushion PRANK with a Raspberry Pi: HOW-TO

Explore the world of Raspberry Pi physical computing with our free FutureLearn courses: http://rpf.io/futurelearn Free make your own Whoopi Cushion resource: http://rpf.io/whoopi For more information on Raspberry Pi and the charitable work of the Raspberry Pi Foundation, including Code Club and CoderDojo, visit http://rpf.io Our resources are free to use in schools, clubs, at home and at events.

Diving deeper

You’ve plundered our projects, you’ve successfully rigged every chair in the house to make rude noises, and now you want to dive deeper into digital making. Good! While you’re digesting your Christmas dinner, take a moment to skim through the Raspberry Pi blog for inspiration. You’ll find projects from across our worldwide community, with everything from home automation projects and retrofit upgrades, to robots, gaming systems, and cameras.

You’ll also find bucketloads of ideas in The MagPi magazine, the official monthly Raspberry Pi publication, available in both print and digital format. You can download every issue for free. If you subscribe, you’ll get a Raspberry Pi Zero W to add to your new collection. HackSpace magazine is another fantastic place to turn for Raspberry Pi projects, along with other maker projects and tutorials.

And, of course, simply typing “Raspberry Pi projects” into your preferred search engine will find thousands of ideas. Sites like Hackster, Hackaday, Instructables, Pimoroni, and Adafruit all have plenty of fab Raspberry Pi tutorials that they’ve devised themselves and that community members like you have created.

And finally

If you make something marvellous with your new Raspberry Pi – and we know you will – don’t forget to share it with us! Our Twitter, Facebook, Instagram and Google+ accounts are brimming with chatter, projects, and events. And our forums are a great place to visit if you have questions about your Raspberry Pi or if you need some help.

It’s good to get together with like-minded folks, so check out the growing Raspberry Jam movement. Raspberry Jams are community-run events where makers and enthusiasts can meet other makers, show off their projects, and join in with workshops and discussions. Find your nearest Jam here.

Have a great festive holiday and welcome to the community. We’ll see you in 2018!
