Stream to Twitch with the push of a button

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/tinkernut-twitch-streaming/

Stream your video gaming exploits to the internet at the touch of a button with the Twitch-O-Matic. Everyone else is doing it, so you should too.

Twitch-O-Matic: Raspberry Pi Twitch Streaming Device – Weekend Hacker #1804

Some gaming consoles make it easy to stream to Twitch, some gaming consoles don’t (come on, Nintendo). So for those that don’t, I’ve made this beta version of the “Twitch-O-Matic”. No it doesn’t chop onions or fold your laundry, but what it DOES do is stream anything with HDMI output to your Twitch channel with the simple push of a button!

eSports and online game streaming

Interest in eSports has skyrocketed over the last few years, with viewership numbers in the hundreds of millions, sponsorship deals increasing in value and prestige, and tournament prize funds reaching millions of dollars. So it’s no wonder that more and more gamers are starting to stream live to online platforms in order to boost their fanbase and try to cash in on this growing industry.

Streaming to Twitch

Launched in 2011, Twitch.tv is an online live-streaming platform with a primary focus on video gaming. Users can create accounts to contribute their comments and content to the site, as well as watching live-streamed gaming competitions and broadcasts. With a staggering fifteen million daily users, Twitch is accessible via smartphone and gaming console apps, smart TVs, computers, and tablets. But if you want to stream to Twitch, you may find yourself using third-party software in order to do so. And with more buttons to click and more wires to plug in for older, app-less consoles, streaming can get confusing.

Enter Tinkernut.

Side note: we ❤ Tinkernut

We’ve featured Tinkernut a few times on the Raspberry Pi blog – his tutorials are clear, his projects are interesting and useful, and his live-streamed comment videos for every build are a nice touch to sharing homebrew builds on the internet.

Tinkernut Raspberry Pi Zero W Twitch-O-Matic

So, yes, we love him. [This is true. Alex never shuts up about him. – Ed.] And since he has over 500K subscribers on YouTube, we’re obviously not the only ones. We wave our Tinkernut flags with pride.

Twitch-O-Matic

With a Raspberry Pi Zero W, an HDMI to CSI adapter, and a case to fit it all in, Tinkernut’s Twitch-O-Matic allows easy connection to the Twitch streaming service. You’ll also need a button – the bigger, the better in our opinion, though Tinkernut has opted for the Adafruit 16mm Illuminated Pushbutton for his build, and not the 100mm Massive Arcade Button that, sadly, we still haven’t found a reason to use yet.

“I’m sorry, Dave…”

For added frills and pizzazz, Tinketnut has also incorporated Adafruit’s White LED Backlight Module into the case, though you don’t have to do so unless you’re feeling super fancy.

The setup

The Raspberry Pi Zero W is connected to the HDMI to CSI adapter via the camera connector, in the same way you’d attach the camera ribbon. Tinkernut uses a standard Raspbian image on an 8GB SD card, with SSH enabled for remote access from his laptop. He uses the simple command Raspivid to test the HDMI connection by recording ten seconds of video footage from his console.

Tinkernut Raspberry Pi Zero W Twitch-O-Matic

One lead is all you need

Once you have the Pi receiving video from your console, you can connect to Twitch using your Twitch stream key, which you can find by logging in to your account at Twitch.tv. Tinkernut’s tutorial gives you all the commands you need to stream from your Pi.

The frills

To up the aesthetic impact of your project, adding buttons and backlights is fairly straightforward.

Pretty LED frills

To run the stream command, Tinketnut uses a button: press once to start the stream, press again to stop. Pressing the button also turns on the LED backlight, so it’s obvious when streaming is in progress.

The tutorial

For the full code and 3D-printable case STL file, head to Tinketnut’s hackster.io project page. And if you’re already using a Raspberry Pi for Twitch streaming, share your build setup with us. Cheers!

The Grafana Labs team will also hit the road for a few weeks starting with Percona Live in Santa Clara, CA, April 23-25 which we are speaking at and sponsoring, followed by KubeCon + CloudNativeCon Europe 2018 in Copenhagen, Denmark, May 2-4, which we are also speaking at and sponsoring.

[$] A new package index for Python

Post Syndicated from jake original https://lwn.net/Articles/751458/rss

The Python Package Index (PyPI) is
the principal repository of libraries for the Python programming language,
serving more than 170 million downloads each week. Fifteen years after PyPI
launched, a new edition is in beta at pypi.org, with features like better
search, a refreshed layout, and Markdown README files
(and with some old
features removed, like viewing GPG package signatures). Starting
April 16, users visiting the site or running pip install will
be
seamlessly redirected to the new site. Two weeks after that, the legacy site is
expected to be shut down and the team will turn toward new
features; in the meantime, it is worth a look at what the new PyPI brings
to the table.

Introducing Backblaze’s Rapid Ingest Service: B2 Fireball

Post Syndicated from Ahin Thomas original https://www.backblaze.com/blog/introducing-backblazes-rapid-ingest-service-fireball/

Introducing Backblaze Fireball

Backblaze’s rapid ingest service, Fireball, graduates out of public beta. Our device holds 70 terabytes of customer data and is perfect for migrating large data sets to B2 Cloud Storage.

At Backblaze, we like to put ourselves in the customer’s shoes. Specifically, we ask questions like “how can we make cloud storage more useful?” There is a long list of things we can do to help — over the last few weeks, we’ve addressed some of them when we lowered the cost of downloading data to $0.01 / GB. Today, we are pleased to publicly release our rapid ingest service, Fireball.

What is the Backblaze B2 Fireball?

The Fireball is a hardware device, specifically a NAS device. Any Backblaze B2 customer can order it from inside their account. The Fireball device can hold up to 70 terabytes of data. Upon ordering, it ships from a Backblaze data center to you. When you receive it, you can transfer your data onto the Fireball using your internal network. Once your data transfer is complete, you send it back to a Backblaze data center. Finally, inside our secure data center, your data is uploaded from the Fireball to your account. Your data remains encrypted throughout the process. Step by step instructions can be found here.

What is Fireball?

Why Use the Fireball?

“We would not have been able to get this project off the ground without the B2 Fireball.” — James Cole, KLRU (Austin City Limits)

For most customers, transferring large quantities of data isn’t always simple. The need can arise as you migrate off of legacy systems (e.g. replacing LTO) or simply on a project basis (e.g. transferring video shot in the field to the cloud). An common approach is to upload your data via the internet to the cloud storage vendor of your choosing. While cloud storage vendors don’t charge for uploads, you have to pay your network provider for bandwidth. That’s assuming you are in a place where the bandwidth can be secured.

Your data is stored in megabytes (“MB”) but your bandwidth is measured in megabits per second (“Mbps”). The difference? An 80 Mbps upload connection will transfer no more than 10 MB per second. That means, in your best case scenario, you might be able to upload 50 terabytes in 50 days, assuming you use nearly all of your upload bandwidth for the upload.

If you’re looking to migrate old backups from LTO or even a large project, a 3 month lag time is not operationally viable. That’s why multiple cloud storage providers have introduced rapid ingest devices.

How It Compares: Backblaze B2 Fireball vs AWS Snowball vs GCS Transfer Appliance

“We found the B2 Fireball much simpler and easier to use than Amazon’s Snowball. WunderVu had been looking for a cloud solution for security and simplicity, and B2 hit every check box.” — Aaron Rhodes, Executive Producer, WunderVu

Every vendor that offers a rapid ingest service only lets you upload to that vendor’s cloud. For example, you can’t use an Amazon Snowball to upload to Google Cloud Storage. This means that when considering a rapid ingest service, you are also making a decision on what cloud storage vendor to use. As such, one should consider not only the cost of the rapid ingest service, but also how much that vendor is going to charge you to store and download your data.

*AWS does not estimate shipping fees at the time of the Snowball order.

To make the comparison easier, let’s create a hypothetical case and compare the costs incurred in the first year. Assume you have 100 TB as an initial upload. But that’s just the initial upload. Over the course of the year, let’s consider a usage pattern where every month you add 5 TB, delete 2 TBs, and download 10 TBs.

Just looking at the first year, Amazon is 337% more expensive than Backblaze and Google is 374% more expensive than Backblaze.

Put simply, Backblaze offers the lowest cost, high performance cloud storage on the planet. During our public beta of the Fireball program we’ve had extremely positive feedback around how the Fireball enables customers to get their projects started in a time efficient and cost effective way. We hope you’ll give it a try!

Happy birthday to us!

Post Syndicated from Eben Upton original https://www.raspberrypi.org/blog/happy-birthday-2018/

The eagle-eyed among you may have noticed that today is 28 February, which is as close as you’re going to get to our sixth birthday, given that we launched on a leap day. For the last three years, we’ve launched products on or around our birthday: Raspberry Pi 2 in 2015; Raspberry Pi 3 in 2016; and Raspberry Pi Zero W in 2017. But today is a snow day here at Pi Towers, so rather than launching something, we’re taking a photo tour of the last six years of Raspberry Pi products before we don our party hats for the Raspberry Jam Big Birthday Weekend this Saturday and Sunday.

Prehistory

Before there was Raspberry Pi, there was the Broadcom BCM2763 ‘micro DB’, designed, as it happens, by our very own Roger Thornton. This was the first thing we demoed as a Raspberry Pi in May 2011, shown here running an ARMv6 build of Ubuntu 9.04.

BCM2763 micro DB

Ubuntu on Raspberry Pi, 2011-style

A few months later, along came the first batch of 50 “alpha boards”, designed for us by Broadcom. I used to have a spreadsheet that told me where in the world each one of these lived. These are the first “real” Raspberry Pis, built around the BCM2835 application processor and LAN9512 USB hub and Ethernet adapter; remarkably, a software image taken from the download page today will still run on them.

We shot some great demos with this board, including this video of Quake III:

Raspberry Pi – Quake 3 demo

A little something for the weekend: here’s Eben showing the Raspberry Pi running Quake 3, and chatting a bit about the performance of the board. Thanks to Rob Bishop and Dave Emett for getting the demo running.

Pete spent the second half of 2011 turning the alpha board into a shippable product, and just before Christmas we produced the first 20 “beta boards”, 10 of which were sold at auction, raising over £10000 for the Foundation.

The beginnings of a Bramble

Beta boards on parade

Here’s Dom, demoing both the board and his excellent taste in movie trailers:

Raspberry Pi Beta Board Bring up

See http://www.raspberrypi.org/ for more details, FAQ and forum.

Launch

Rather to Pete’s surprise, I took his beta board design (with a manually-added polygon in the Gerbers taking the place of Paul Grant’s infamous red wire), and ordered 2000 units from Egoman in China. After a few hiccups, units started to arrive in Cambridge, and on 29 February 2012, Raspberry Pi went on sale for the first time via our partners element14 and RS Components.

Unboxing continues

The first Raspberry Pi from the first box from the first pallet

We took over 100000 orders on the first day: something of a shock for an organisation that had imagined in its wildest dreams that it might see lifetime sales of 10000 units. Some people who ordered that day had to wait until the summer to finally receive their units.

Evolution

Even as we struggled to catch up with demand, we were working on ways to improve the design. We quickly replaced the USB polyfuses in the top right-hand corner of the board with zero-ohm links to reduce IR drop. If you have a board with polyfuses, it’s a real limited edition; even more so if it also has Hynix memory. Pete’s “rev 2” design made this change permanent, tweaked the GPIO pin-out, and added one much-requested feature: mounting holes.

Revision 1 versus revision 2

If you look carefully, you’ll notice something else about the revision 2 board: it’s made in the UK. 2012 marked the start of our relationship with the Sony UK Technology Centre in Pencoed, South Wales. In the five years since, they’ve built every product we offer, including more than 12 million “big” Raspberry Pis and more than one million Zeros.

Celebrating 500,000 Welsh units, back when that seemed like a lot

Economies of scale, and the decline in the price of SDRAM, allowed us to double the memory capacity of the Model B to 512MB in the autumn of 2012. And as supply of Model B finally caught up with demand, we were able to launch the Model A, delivering on our original promise of a $25 computer.

A UK-built Raspberry Pi Model A

In 2014, James took all the lessons we’d learned from two-and-a-bit years in the market, and designed the Model B+, and its baby brother the Model A+. The Model B+ established the form factor for all our future products, with a 40-pin extended GPIO connector, four USB ports, and four mounting holes.

The Raspberry Pi 1 Model B+ — entering the era of proper product photography with a bang.

New toys

While James was working on the Model B+, Broadcom was busy behind the scenes developing a follow-on to the BCM2835 application processor. BCM2836 samples arrived in Cambridge at 18:00 one evening in April 2014 (chips never arrive at 09:00 — it’s always early evening, usually just before a public holiday), and within a few hours Dom had Raspbian, and the usual set of VideoCore multimedia demos, up and running.

We launched Raspberry Pi 2 at the start of 2015, pairing BCM2836 with 1GB of memory. With a quad-core Arm Cortex-A7 clocked at 900MHz, we’d increased performance sixfold, and memory fourfold, in just three years.

Nobody mention the xenon death flash.

And of course, while James was working on Raspberry Pi 2, Broadcom was developing BCM2837, with a quad-core 64-bit Arm Cortex-A53 clocked at 1.2GHz. Raspberry Pi 3 launched barely a year after Raspberry Pi 2, providing a further doubling of performance and, for the first time, wireless LAN and Bluetooth.

All our recent products are just the same board shot from different angles

Zero to hero

Where the PC industry has historically used Moore’s Law to “fill up” a given price point with more performance each year, the original Raspberry Pi used Moore’s law to deliver early-2000s PC performance at a lower price. But with Raspberry Pi 2 and 3, we’d gone back to filling up our original $35 price point. After the launch of Raspberry Pi 2, we started to wonder whether we could pull the same trick again, taking the original Raspberry Pi platform to a radically lower price point.

The result was Raspberry Pi Zero. Priced at just $5, with a 1GHz BCM2835 and 512MB of RAM, it was cheap enough to bundle on the front of The MagPi, making us the first computer magazine to give away a computer as a cover gift.

Cheap thrills

MagPi issue 40 in all its glory

We followed up with the $10 Raspberry Pi Zero W, launched exactly a year ago. This adds the wireless LAN and Bluetooth functionality from Raspberry Pi 3, using a rather improbable-looking PCB antenna designed by our buddies at Proant in Sweden.

Up to our old tricks again

Other things

Of course, this isn’t all. There has been a veritable blizzard of point releases; RAM changes; Chinese red units; promotional blue units; Brazilian blue-ish units; not to mention two Camera Modules, in two flavours each; a touchscreen; the Sense HAT (now aboard the ISS); three compute modules; and cases for the Raspberry Pi 3 and the Zero (the former just won a Design Effectiveness Award from the DBA). And on top of that, we publish three magazines (The MagPi, Hello World, and HackSpace magazine) and a whole host of Project Books and Essentials Guides.

Forward the Foundation

Why does all this matter? Because we’re providing everyone, everywhere, with the chance to own a general-purpose programmable computer for the price of a cup of coffee; because we’re giving people access to tools to let them learn new skills, build businesses, and bring their ideas to life; and because when you buy a Raspberry Pi product, every penny of profit goes to support the Raspberry Pi Foundation in its mission to change the face of computing education.

We’ve had an amazing six years, and they’ve been amazing in large part because of the community that’s grown up alongside us. This weekend, more than 150 Raspberry Jams will take place around the world, comprising the Raspberry Jam Big Birthday Weekend.

Security Breaches Don’t Affect Stock Price

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/01/security_breach.html

Interesting research: “Long-term market implications of data breaches, not,” by Russell Lange and Eric W. Burger.

Abstract: This report assesses the impact disclosure of data breaches has on the total returns and volatility of the affected companies’ stock, with a focus on the results relative to the performance of the firms’ peer industries, as represented through selected indices rather than the market as a whole. Financial performance is considered over a range of dates from 3 days post-breach through 6 months post-breach, in order to provide a longer-term perspective on the impact of the breach announcement.

Key findings:

  • While the difference in stock price between the sampled breached companies and their peers was negative (1.13%) in the first 3 days following announcement of a breach, by the 14th day the return difference had rebounded to + 0.05%, and on average remained positive through the period assessed.
  • For the differences in the breached companies’ betas and the beta of their peer sets, the differences in the means of 8 months pre-breach versus post-breach was not meaningful at 90, 180, and 360 day post-breach periods.

  • For the differences in the breached companies’ beta correlations against the peer indices pre- and post-breach, the difference in the means of the rolling 60 day correlation 8 months pre- breach versus post-breach was not meaningful at 90, 180, and 360 day post-breach periods.

  • In regression analysis, use of the number of accessed records, date, data sensitivity, and malicious versus accidental leak as variables failed to yield an R2 greater than 16.15% for response variables of 3, 14, 60, and 90 day return differential, excess beta differential, and rolling beta correlation differential, indicating that the financial impact on breached companies was highly idiosyncratic.

  • Based on returns, the most impacted industries at the 3 day post-breach date were U.S. Financial Services, Transportation, and Global Telecom. At the 90 day post-breach date, the three most impacted industries were U.S. Financial Services, U.S. Healthcare, and Global Telecom.

The market isn’t going to fix this. If we want better security, we need to regulate the market.

Running out of cash is one of the quickest ways for a startup to go out of business. When you are starting a company the question of where to get cash is usually the top priority, but managing cash flow is critical for every stage in the lifecycle of a company. As a primarily bootstrapped but capital-intensive business, managing cash flow at Backblaze was and still is a key element of our success and requires continued focus. Let’s look at what we learned over the years.

Raising Your Initial Funding

When starting a tech business in Silicon Valley, the default assumption is that you will immediately try to raise venture funding. There are certainly many advantages to raising funding — not the least of which is that you don’t need to be cash-flow positive since you have cash in the bank and the expectation is that you will have a “burn rate,” i.e. you’ll be spending more than you make.

Note: While you’re not expected to be cash-flow positive, that doesn’t mean you don’t have to worry about cash. Cash-flow management will determine your burn rate. Whether you can get to cash-flow breakeven or need to raise another round of funding is a direct byproduct of your cash flow management.

Also, raising funding takes time (most successful fundraising cycles take 3-6 months start-to-finish), and time at a startup is in short supply. Constantly trying to raise funding can take away from product development and pursuing growth opportunities. If you’re not successful in raising funding, you then have to either shut down or find an alternate method of funding the business.

Sources of Funding

Depending on the stage of the company, type of company, and other factors, you may have access to different sources of funding. Let’s list a number of them:

Customers

Sales — the best kind of funding. It is non-dilutive, doesn’t have to be paid back, and is a direct metric of the success of your company.

Pre-Sales — some customers may be willing to pay you for a product in beta, a test, or pre-pay for a product they’ll receive when finished. Pre-Sales income also is great because it shares the characteristics of cash from sales, but you get the cash early. It also can be a good sign that the product you’re building fills a market need. We started charging for Backblaze computer backup while it was still in private beta, which allowed us to not only collect cash from customers, but also test the billing experience and users’ real desire for the service.

Services — if you’re a service company and customers are paying you for that, great. You can effectively scale for the number of hours available in a day. As demand grows, you can add more employees to increase the total number of billable hours.

Note: If you’re a product company and customers are paying you to consult, that can provide much needed cash, and could provide feedback toward the right product. However, it can also distract from your core business, send you down a path where you’re building a product for a single customer, and addict you to a path that prevents you from building a scalable business.

Investors

Yourself — you likely are putting your time into the business, and deferring salary in the process. You may also put your own cash into the business either as an investment or a loan.

Angels — angels are ideal as early investors since they are used to investing in businesses with little to no traction. AngelList is a good place to find them, though finding people you’re connected with through someone that knows you well is best.

Crowdfunding — a component of the JOBS Act permitted entrepreneurs to raise money from nearly anyone since May 2016. The SEC imposes limits on both investors and the companies. This article goes into some depth on the options and sites available.

VCs — VCs are ideal for companies that need to raise at least a few million dollars and intend to build a business that will be worth over $1 billion.

Debt

Friends & Family — F&F are often the first people to give you money because they are investing in you. It’s great to have some early supporters, but it also can be risky to take money from people who aren’t used to the risks. The key advice here is to only take money from people who won’t mind losing it. If someone is talking about using their children’s college funds or borrowing from their 401k, say ‘no thank you’ — even if they’re sure they want to loan you money.

Bank Loans — a variety of loan types exist, but most either require the company to have been operational for a couple years, be able to borrow against money the company has or is making, or be able to get a personal guarantee from the founders whereby their own credit is on the line. Fundera provides a good overview of loan options and can help secure some, but most will not be an option for a brand new startup.

Grants

Government — in some areas there is the potential for government grants to facilitate research. The SBIR program facilitates some such grants.

At Backblaze, we used a number of these options:

• Investors/Yourself
We loaned a cumulative total of a couple hundred thousand dollars to the company and invested our time by going without a salary for a year and a half.
• Customers/Pre-Sales
We started selling the Backblaze service while it was still in beta.
• Customers/Sales
We launched v1.0 and kept selling.
• Investors/Angels
After a year and a half, we raised $370k from 11 angels. All of them were either people whom we knew personally or were a strong recommendation from a mutual friend.
• Debt/Loans
After a couple years we were able to get equipment leases whereby the Storage Pods and hard drives were used as collateral to secure the lease on them.
• Investors/VCs
Ater five years we raised $5m from TMT Investments to add to the balance sheet and invest in growth.

The variety and quantity of sources we used is by no means uncommon.

GAAP vs. Cash

Most companies start tracking financials based on cash, and as they scale they switch to GAAP (Generally Accepted Accounting Principles). Cash is easier to track — we got paid $XXXX and spent $YYY — and as often mentioned, is required for the business to stay alive. GAAP has more subtlety and complexity, but provides a clearer picture of how the business is really doing. Backblaze was on a ‘cash’ system for the first few years, then switched to GAAP. For this post, I’m going to focus on things that help cash flow, not GAAP profitability.

Stages of Cash Flow Management

All-spend

In a pure service business (e.g. solo proprietor law firm), you may have no expenses other than your time, so this stage doesn’t exist. However, in a product business there is a period of time where you are building the product and have nothing to sell. You have zero cash coming in, but have cash going out. Your cash-flow is completely negative and you need funds to cover that.

Sales-generating

Starting to see cash come in from customers is thrilling. I initially had our system set up to email me with every $5 payment we received. You’re making sales, but not covering expenses.

Ramen-profitable

But it takes a lot of $5 payments to pay for servers and salaries, so for a while expenses are likely to outstrip sales. Getting to ramen-profitable is a critical stage where sales cover the business expenses and are “paying enough for the founders to eat ramen.” This extends the runway for a business, but is not completely sustainable, since presumably the founders can’t (or won’t) live forever on a subsistence salary.

Business-profitable

This is the ultimate stage whereby the business is truly profitable, including paying everyone market-rate salaries. A business at this stage is self-sustaining. (Of course, market shifts and plenty of other challenges can kill the business, but cash-flow issues alone will not.)

Note, I’m using the word ‘profitable’ here to mean this is still on a cash-basis.

Backblaze was in the all-spend stage for just over a year, during which time we built the service and hadn’t yet made the service available to customers. Backblaze was in the sales-generating stage for nearly another year before the company was barely ramen-profitable where sales were covering the company expenses and paying the founders minimum wage. (I say ‘barely’ since minimum wage in the SF Bay Area is arguably never subsistence.) It took almost three more years before the company was business-profitable, paying everyone including the founders market-rate.

Cash Flow Forecasting

When raising funding it’s helpful to think of milestones reached. You don’t necessarily need enough cash on day one to last for the next 100 years of the company. Some good milestones to consider are how much cash you need to prove there is a market need, prove you can build a product to meet that need, or get to ramen-profitable.

Two things to consider:

1) Unit Economics (COGS)

If your product is 100% software, this may not be relevant. Once software is built it costs effectively nothing to deliver the product to one customer or one million customers. However, in most businesses there is some incremental cost to provide the product. If you’re selling a hardware device, perhaps you sell it for $100 but it costs you $50 to make it. This is called “COGS” (Cost of Goods Sold).

Many products rely on cloud services where the costs scale with growth. That model works great, but it’s still important to understand what the costs are for the cloud service you use per unit of product you sell.

Support is often done by the founders early-on in a business, but that is another real cost to factor in and estimate on a per-user basis. Taking all of the per unit costs combined, you may charge $10/month/user for your service, but if it costs you $7/month/user in cloud services, you’re only netting $3/month/user.

2) Operating Expenses (OpEx)

These are expenses that don’t scale with the number of product units you sell. Typically this includes research & development, sales & marketing, and general & administrative expenses. Presumably there is a certain level of these functions required to build the product, market it, sell it, and run the organization. You can choose to invest or cut back on these, but you’ll still make the same amount per product unit.

Incremental Net Profit Per Unit

If you’ve calculated your COGS and your unit economics are “upside down,” where the amount you charge is less than that it costs you to provide your service, it’s worth thinking hard about how that’s going to change over time. If it will not change, there is no scale that will make the business work. Presuming you do make money on each unit of product you sell — what is sometimes referred to as “Contribution Margin” — consider how many of those product units you need to sell to cover your operating expenses as described above.

Calculating Your Profit

The math on getting to ramen-profitable is simple:

(Number of Product Units Sold x Contribution Margin) - Operating Expenses = Profit

If your operating expenses include subsistence salaries for the founders and profit > $0, you’re ramen-profitable.

Improving Cash Flow

Having access to sources of cash, whether from selling to customers or other methods, is excellent. But needing less cash gives you more choices and allows you to either dilute less, owe less, or invest more.

There are two ways to improve cash flow:

1) Collect More Cash

The best way to collect more cash is to provide more value to your customers and as a result have them pay you more. Additional features/products/services can allow this. However, you can also collect more cash by changing how you charge for your product. If you have a subscription, changing from charging monthly to yearly dramatically improves your cash flow. If you have a product that customers use up, selling a year’s supply instead of selling them one-by-one can help.

2) Spend Less Cash

Reducing COGS is a fantastic way to spend less cash in a scalable way. If you can do this without harming the product or customer experience, you win. There are a myriad of ways to also reduce operating expenses, including taking sub-market salaries, using your home instead of renting office space, staying focused on your core product, etc.

Ultimately, collecting more and spending less cash dramatically simplifies the process of getting to ramen-profitable and later to business-profitable.

Be Careful (Why GAAP Matters)

A word of caution: while running out of cash will put you out of business immediately, overextending yourself will likely put you out of business not much later. GAAP shows how a business is really doing; cash doesn’t. If you only focus on cash, it is possible to commit yourself to both delivering products and repaying loans in the future in an unsustainable fashion. If you’re taking out loans, watch the total balance and monthly payments you’re committing to. If you’re asking customers for pre-payment, make sure you believe you can deliver on what they’ve paid for.

Summary

There are numerous challenges to building a business, and ensuring you have enough cash is amongst the most important. Having the cash to keep going lets you keep working on all of the other challenges. The frameworks above were critical for maintaining Backblaze’s cash flow and cash balance. Hopefully you can take some of the lessons we learned and apply them to your business. Let us know what works for you in the comments below.
