Raspberry Pi Oracle Weather Stations shipped

Big brown boxes
If this blog was an Ealing comedy, it would be a speeded-up montage of an increasingly flustered postman delivering huge numbers of huge boxes to school reception desks across the land. At the end, they’d push their cap up at a jaunty angle and wipe their brow with a large spotted handkerchief. With squeaky sound effects.
Over the past couple of days, huge brown boxes have indeed been dropping onto the counters of school receptions across the UK, and they contain something wonderful— a Raspberry Pi Oracle Weather Station.

Pilot “lite”
We’re running the UK delivery as a short pilot scheme. With almost 1000 schools involved worldwide, it will give us a chance us to tweak software and resources, and to get a feel for how we can best support schools.  In the next few weeks, we’ll send out the remainder of the weather stations. We’ll have a good idea of when this will be next week, when the first kits have been in schools for a while.
Once all the stations are shipped, we’ll be extending and expanding our teaching and learning resources. In particular, we would like resources for big data management and visualisation, and for non-computing subjects such as geography.  And, of course, if you make any of your own we’d love to see them.

 “Just” a milestone
This is a big milestone for the project, but it’s not the end by any means. In fact, it’s just the beginning as schools start to build their stations, using them to investigate the weather and to learn. We’re hoping to see and encourage lots of collaboration between schools. We started the project back in 2014. Over time, it’s easy to take any project for granted, so it was brilliant to see the excitement of teachers and students when they received their kit.

It’s been a fun two years, and if you’ve opened a big brown box this morning and found a weather station inside, we think you’ll agree that it’s been worth the wait.
Building and setting up your weather station
The weather station page has tutorials for building the hardware and setting up the software for your weather station, along with a scheme of work for teachers and other resources.
Getting involved
The community is hugely important to us and whether you’ve just received a weather station or not, we’d love to hear from you.  The best way to get involved is to come to the friendly Weather Station corner of our forums and say hi. This is also the place to get help and to share ideas. If you’re tweeting, then you can reach us @raspberry_pi or on the hashtag #weatherstation – thanks!

Buying the kit
We’re often asked if we’ll be selling the kits. We’re currently looking into this and hope that they will be commercially available at some point. I’d love to see a Raspberry Pi Weather Station attached to every school – it’s a project that genuinely engages students across many subjects. In addition, the data gathered from thousands of weather stations, all sending data back to a central database, would be really useful.
That’s all for now
But now that the kits are shipped there’ll be lots going on, so expect more news soon. And do pop into the forums for a chat.
Thanks
As well as the talented and lovely folk at Pi Towers, we’ve only made it this far with the help of others. At risk of turning into a mawkish awards ceremony speech, a few shout-outs are needed:
Oracle for their generous funding and the database support, especially Nicole at Oracle Giving, Jane at Oracle Academy, and Jeff who built our Apex database.
Rachel, Kevin and Team @cpc_tweet for the kit build (each kit has around 80 parts!) and amazing logistics support.
@HackerJimbo for sterling software development and the disk image.
If I’ve missed you out, it doesn’t mean I don’t love you.

This month — which I will pretend is still February, because time zones or something — Vladimir Costescu has sponsored a post on:

OK, how about this: write a post on what you think about (the concept of) Valentine’s Day. Bonus points if you write a brief commentary on this video and work it into the post somehow.

I… I’m afraid I don’t know how to work death metal performed by vampires into a post about anything else.

But Valentine’s Day, I think I can do.

Lupercalia

I guess it’s interesting to look into where it came from.

The Internet tells me that Valentine’s Day, much like every other interesting holiday, is rooted in an ancient Roman festival called Lupercalia and held on February 13 through 15.

I say “festival”, but, uh. It involved sacrificing a goat and a dog, cutting the goat’s hide into strips, dipping the strips into the goat’s own blood, and then running around town wearing a goatskin and slapping (whipping?) women with the strips. Probably while drunk. But the women were generally on board, because this was supposed to make them fertile. Oh, and the people doing this were priests, of course.

Then they’d have a hookup lottery, where all the single ladies would put their names in a jar, and a guy could draw a name, and the pair would go shack up for the night or maybe the year.

All of this was in service of the god Lupercus, the god of — you guessed it — shepherds.

You zany Romans.

I found half a dozen different descriptions of this holiday that explain it half a dozen very different ways, so I’m going to avoid elaborating too much for fear someone will think I know what I’m talking about. The goal seems to have been a bit fuzzy, anything from purification to fertility to honoring the founders of Rome to just an excuse to drink and eat a lot. About as consistent as our modern holidays, then.

It seems this festival overtook an earlier one called Februalia, which was a purification celebration — essentially, spring cleaning. That’s what February is named for. So there is in fact a very distant tie between the very month of February and Valentine’s Day. Neat. (There was also a god of purification named Februus, though in an interesting twist, he came later and thus was named after the festival/month, not the other way around.)

The chain of events thusfar is something like: it rains in spring, which led to a cleaning festival, which was somehow co-opted by a purification festival, which also involved fertility rites.

I’m pretty sure we don’t still do the goat-blood-slapping thing, so something else must have happened.

Valentine

During the 200s, the Roman Emperor was Claudius II, a man who was tragically unaware that the decline of the Roman Empire had begun in 190.

The first thing I read was that he had the goofy idea that unmarried men made better soldiers than married men, so he decreed it illegal for young people to marry. Some Christian priests were officiating weddings in secret, and one of them was named Valentine, and that’s why he was executed. This is all according to some Christian website that’s really trying to drive home the martyrdom angle.

But then I checked the liberal hedonistic pit Wikipedia, and it tells me that no such decree was ever issued, which rather puts a hole in the story.

Regardless, there was definitely a Christian priest named Valentime who was executed on February 14, 269. Apocryphally, his last words were a note that he signed “your Valentine”. And then he had his head cut off. Aww.

Astoundingly, Claudius had another Valentine put to death exactly four years later — on February 14, 273. A third Valentine may also have been executed in Africa on February 14, but nobody knows any specifics.

It was a couple hundred years before the reigning pope decided that this Lupercalia thing simply had to go, and invoked that most hallowed of Christian traditions: stamping out a pagan holiday by making up a new one on the same day. And so February 14 became St. Valentine’s Day. It probably should’ve been St. Valentines’ Day.

Or, uh, so the story goes, but this is pretty murky too. I’m not sure if the reuse of the date was intentional, or a huge coincidence — frankly, given how many festivals the Romans had, they’d have had a hard time inventing a new holiday that didn’t overlap an existing Roman thing. I also have absolutely no idea what St. Valentines’ Day was actually for, insofar as days devoted to saints are actually for anything in particular. The best I’ve found is “feasting”.

Romance

A few casual retellings of this story implicitly (or even explicitly) link St. Valentines’ Day directly to romance right from the beginning, based on the marriage story. But it seems that there’s no record of any romantic connotations until a poem written by Chaucer in 1382, which is extra weird because he seemed to be nodding at an existing tradition. Another nod appears in a charter written in 1400, founding a court which by all other appearances seemed to never have existed.

Reading about this has been a truly surreal experience. I initially avoided looking at Wikipedia for fear I would just end up paraphrasing it, and instead found a dozen conflicting stories that all turned out to be wrong anyway. The actual history (well, as told by Wikipedia) appears to be full of huge gaps that we just don’t know anything about. All I can really say for sure is that Valentine’s Day exists, at least one guy named Valentine was once put to death on the same day, and the Romans had a festival around the same time.

The rest of the history isn’t nearly so bizarre. In the early 1800s, companies started printing pre-made Valentine cards, and cheap postage made it feasible to mail them around. Momentum built from there, and of course, anyone with something vaguely romantic to sell latched on.

Modern day

I can’t remember ever doing anything particularly romantic for Valentine’s Day. No one in this house is really big on holidays; we don’t even do anything special for Christmas. So I don’t have particularly strong feelings here.

In fact, my strongest association with the day is still from grade school. I don’t know if this is a cultural or regional thing or what, but I had multiple teachers who expected every student to go buy one of those big boxes of 30 cheesy Valentine’s Day cards branded with popular cartoons or whatever and give one to every other student.

I never understood this. I still don’t. I can see how it might have come about: kids exchange cards, some kids don’t get any, they feel bad, teachers see an obvious way to compensate. But then what’s the point of doing it at all? What does this even have to do with romance any more? Did it ever, considering I wasn’t even 10 when this was happening, or was it always a goofy popularity contest?

Here’s a better tradition for young kids, I think: the teacher buys a mountain of chocolate and gives it out. It’s based on my own tradition of buying a mountain of discount chocolate on February 15. Everyone wins!

Come to think of it, those incredibly cheesy cards might be one of my favorite parts of Valentine’s Day. Not the mass-produced Spongebob ones, but knowingly-corny ones created by artists, like the set Mel made a few years ago (some of which only make sense in the context of a story they were telling at the time). I heart-ily endorse creating more of this kind of nonsense.

Another hallowed tradition is for single people to lament that they’re single. I guess, anyway. Like the Super Bowl thing from a few weeks ago, this is something I’ve seen complained about much more than I’ve seen actually happen. I don’t really know anything about human mating rituals, but lamenting one’s lack of a partner seems exactly opposite to the spirit of Valentine’s Day, which at its heart seems to be about flirting. Whether there’s an actual connection or not, maybe that Roman holiday had it right: everyone should put their names in an urn, draw partners at random, and hook up for a night. While dressed up as goats. That sounds like a good plan.


Hmm. I just don’t really have a lot to say here. Valentine’s Day is the pink and red holiday that fills the seasonal aisle after Christmas but before the Easter candy has been stocked. It comes, and it goes, and I think once we used it as an excuse to go to a restaurant. Its history is more confusing than outrageous, and its modern incarnation is a fairly quiet blip on the calendar. So I think that’s all I’ve got. Sorry 🙂

The GNU GPL and the American Dream

Post Syndicated from Bradley M. Kuhn original http://ebb.org/bkuhn/blog/2001/02/21/american-dream.html

[ This essay
was originally
published on gnu.org

When I was in grade school, right here in the United States of America,
I was taught that our country was the “land of opportunity”. My teachers
told me that my country was special, because anyone with a good idea and a
drive to do good work could make a living, and be successful too. They
called it the “American Dream”.

What was the cornerstone to the “American Dream”? It was
equality — everyone had the same chance in our society to choose
their own way. I could have any career I wanted, and if I worked hard, I
would be successful.

It turned out that I had some talent for working with computers —
in particular, computer software. Indoctrinated with the “American
Dream”, I learned as much as I could about computer software. I
wanted my chance at success.

I quickly discovered though, that in many cases, not all the players in
the field of computer software were equal. By the time I entered the
field, large companies like Microsoft tended to control much of the
technology. And, that technology was available to me under licensing
agreements that forbid me to study and learn from it. I was completely
prohibited from viewing the program source code of the software.

I found out, too, that those with lots of money could negotiate
different licenses. If they paid enough, they could get permission to
study and learn from the source code. Typically, such licenses cost many
thousands of dollars, and being young and relatively poor, I was out of
luck.

After spending my early years in the software business a bit
downtrodden by my inability to learn more, I eventually discovered another
body of software that did allow me to study and learn. This software was
released under a license called the GNU General Public License (GNU
GPL). Instead of restricting my freedom to study and learn from it, this
license was specifically designed to allow me to learn. The license
ensured that no matter what happened to the public versions of the
software, I’d always be able to study its source code.

I quickly built my career around this software. I got lots of work
configuring, installing, administering, and teaching about that
software. Thanks to the GNU GPL, I always knew that I could stay
competitive in my business, because I would always be able to learn easily
about new innovations as soon as they were made. This gave me a unique
ability to innovate myself. I could innovate quickly, and impress my
employers. I was even able to start my own consulting business. My own
business! The pinnacle of the American Dream!

Thus, I was quite surprised last week
when Jim Allchin, a
vice president at
Microsoft hinted
that
the
GNU GPL
contradicted
the
American Way.

The GNU GPL is specifically designed to make sure that all
technological innovators, programmers, and software users are given equal
footing. Each high school student, independent contractor, small business,
and large corporation are given an equal chance to innovate. We all start
the race from the same point. Those people with deep understanding of the
software and an ability to make it work well for others are most likely to
succeed, and they do succeed.

That is exactly what the American Way is about, at least the way I
learned it in grade school. I hope that we won’t let Microsoft and
others change the definition.
