Yeah for the kind of schools that can't afford to have a computer lab, teaching linux programming on an outdated cell phone chipset isn't going to be helpful.

Computer viking posted:How does the OS or hardware matter when teaching a basic introduction to programming course? The only important parts is that the OS+hardware won't create too many problems and that the chosen language isn't entirely braindead. The bigger issue is finding interested and competent teachers, I suspect. Because a school that can't afford normal computers for use in everything else a school needs computers for probably shouldn't have RPis for a programming class.

ante posted:Who said anything about an average computer? The entire ethos of the Pi was, "hey, it would be great if we could send a whole bunch of computers to developing nations and kids under the poverty line. Let's try reeeeaaally hard and get the price down to $35 (crazy cheap)." 65 pounds for a decent high res small display is actually cheap as heck though. Sure you can get a total crap display for under $35 but that's not the point. Plus don't bullshit here. Everyone knows the real point of the Pi was for people relatively well off compared to people in developing countries to have a gently caress around computer that they could use with spare displays and input devices they already have. People actually in developing countries with no computer already would need to buy a decent number of other things in order to actually use a RasPi, same goes for kids under the poverty line.

Even if it is an outdated version of Android, having an OS that was designed for and has a library of applications based around touch screens is a great thing for stuff like car builds. Possibly, but a lot of stuff is still not going to work right given the compromises that had to be made.

PS. Love the cabin posted:HP LaserJet 1000. Ah, yeah, it's one of those printers that cheaps out by having most of the rendering of the pages done on the host computer. Having it eat up a ton of of processing power on a Pi is going to be pretty much unavoidable, sadly, and that will cause other aspects of the printing system to freak out. Back when it was new, you could easily bring an older Pentium III system to its knees printing with one of those printers, and the Pi's roughly on par with one of those for basic computational power.

You sound like you're thissss close to needing an Intel NUC or similar device: http://www.amazon.com/Intel-Computing-Gigabit-i3-3217U-DC3217IYE/dp/B0093LINVK You get bumped up to a full Core i3, it's super compact, it will use real peripherals and in general is much more reliable for your needs.

YouTuber posted:So apparently the Raspberry Pi 2 is announced. Even though it's quad core, the 900 mhz standard clock might be a bit poky. But this is upgrading it from a 2006 smartphone to a lower end 2013 smartphone, which means it'll be a lot more powerful and will certainly run Android very well, especially if you give it a bit of an overclock.

Rexroom posted:It's a cheap hobbyist computer with a strong community of fellow hackers. Kind of like what the Commodore 64 was back in the day. Yes, those examples you gave would probably do the job better, but where's the fun in that? This is more about hacking something cool. After all, this is designed as an educational computer science tool for schools. Ehh I really hate the C64 connection people try to draw with it. C64 was cheap but it also was widespread and a more than decent games machine. It later developed a community of hackers and hobbyists as it started to decline in popularity, yet remained on the shelf at a cheap price point, but it was always focused around "mainstream" usage - it was nearly 50% of the personal computer market all by itself at one point!   A better comparison would be old-fashioned kit computers.

thehustler posted:You know these RTL-SDR dongles that everyone's buying? Apparently they only have a maximum sample bandwidth of 3.2 MHz - how is that possible? If they are digital TV tuners in their past lives, that would require a bandwidth of up to 8MHz (in the UK, at least). Channel bandwidth in the Americas/Japan/Korea is 6 MHz, so yeah something's fishy if it will only do 3.2 MHz for arbitrary analyzing. Or maybe the guys selling them are just under-rating performance to cover their rear end.

It is not really, as it's the restrictive ARM build of Windows. You will never have full windows on a Pi until it gets an x86-64 processor in a future upgrade. There's going to be a rebranding of it, but RT remains the name of the API used, and what the Pi gets is RT by another name.

doctorfrog posted:I guess I was one of the ignorami who didn't look too deeply at Windows 10 on the Pi, but I wasn't expecting a full Win 10 desktop experience, either, but something pretty scaled down, maybe half as flexible as Raspbian, with some disappointing form of their cloud, office, and gaming features roped in. I figured it would be part of MS's attempted entree into schools: cheapo computers with basic computery functions, aimed at poorer schools or better-equipped schools' science and activity labs. That doesn't really make sense. "Use raspberry pis as cheap school computers" has never made sense even if that was the intention. You can't use a Pi 2 without extra keyboard, mouse, display device. You bundle all that up and frankly regular Windows desktops or even low end laptops are cheaper, and significantly more versatile. There are very few situations ever that you'd have usb mice, keyboards, and either composite tvs or hdmi tv/monitors all ready to go in the dozens but no computers, or with computers but they're so old that the Pi or anything like them would be a step up.

baka kaba posted:They weren't meant to be drop-in replacements for PCs, the idea was to have a Computer Science package that's ready to go for any classroom at any level. It comes with a simple language for teaching fundamental concepts to beginners, that teachers with no ICT background can work with (which has always been a concern with this general push to bring computer science to younger children). Right, and they're TERRIBLE for that in comparison to the computers modern schools already have if they could also afford the necessary ancillary kit to actually use the Pis. In my high school in the 2000s, we simply used a free Java IDE for computer science class. Python, poo poo even Pascal or logo (they still put that out you know) are also free or often nearly free for education. If it was designed to be that, it's worked out terribly for it to be frank. Because what they really built was something that was cheap and great for people who already know all about computers, or at least a decent bit. And that's a good thing for it to be, they just didn't seem to realize that that's what it could only really ever be. It reminds me of the original OLPC. They decided to make it gimmicky with some custom Linux OS, then when the actual people who would be receiving them finally got a say, they're like "well we would really prefer if it had a normal OS, preferably Windows, so that we can use the same things the rich folks can". And then people whined about the project being tainted when Microsoft donated free Windows 7 Starter licenses for most of the later ones produced and actually sent overseas.

OLPC was the sort of thing I thought was really neat, but always kinda scratched my head about what the poor African villagers in the pictures were supposed to do when the battery wouldn't hold any kind of charge in 2-3 years, the handle on the charge thing broke, or the kids wanted do something outside of the ghettoized OS it came with. If I remember right at one point the OLPC group considered just dumping unsent OLPCs over villages near the end.

Paul MaudDib posted:The thing is it is also terrible for that, because experienced users want to be able to do things that involve USB 2.0 speeds. For like a couple years the kernel would drop USB packets at 2.0 speeds. Even now, it's a terrible architecture for that because SD card, system disk, external disk, network, webcam, whatever are all hanging off a single 400 Mbps bus. USB ain't made for that. While this is all true, it was still really really cheap which was the main thing. Really these criticisms apply more to the Pi 2 because they coulda fixed that stuff and put a non-9 years-old GPU on it to match with the no-longer-9 years-old CPU but whatever.

Karthe posted:What's preventing anyone from releasing an x86 version of something like the Pi? Is it that the x86 architecture is expensive in general? I think it was in this thread that someone linked a Pi-esque x86 board that was going for a few hundred dollars? Obviously a far cry from $35. Intel has their Compute Stick for around $140. http://www.intel.com/content/www/us/en/compute-stick/intel-compute-stick.html It comes with 1 GB of ram and 8 GB of storage for the cheaper Linux version, or 2 GB ram and 32 GB storage for the more expensive Windows version (either os can be installed on either revision though) It has a quad core modern Atom CPU (which is little to do with the original Atom design) so as far as CPU power goes it's pretty darn beefy, and the Intel gpu isn't bad either. If it sold without casing or the storage it'd probably be decently cheaper.

baka kaba posted:I think y'all are missing the point I'm making, and vastly overestimating the computer skills of the teachers (and assuming all these primary schools have a dedicated IT team to mess around with setting all this stuff up, or make purchasing decisions based on SATA throughput). I think you're vastly underestimating the abilities of teachers in schools that have already had computers for at least a decade if not more. Or the difficulty of teaching computer stuff when your district simply shells out for training the teachers instead of buying a bunch of Raspberry Pis and the neccesary equipment to actually use them. Kids can't actually take the devices outside school and use them effectively without also having spare equipment at home, which most of them won't have. And the pins are utterly irrelevant to teaching basic computer stuff. The actual computers your schools have will have plenty of visual programming languages and other such things to use. The Raspberry Pi is in no way easier for your random school teacher to use then the computers they already have access to. They may have tried to design them for that, but they failed.
