SwissCM posted:Well at least the launch wasn't as botched as it was with the OpenPandora. That launched fine, its the delivery that's botched there. Neat thing about that little dealie is that because it's taken so long to be built and sent out, everyone beyond the first 2000 orders gets 512 MB of RAM in it instead of 256 MB. Because the lower RAM amount is impossible to supply, due to the chips being declared obsolete and no longer manufactured, so they had to upgrade the RAM amount in order to have supply.

Toad King posted:Where exactly did you hear that? I know the Model A got a boost to 256 MB, but this is the first I've heard of all of them models going to 512. I'm referring to the OpenPandora in that post. It's had orders delayed so long that parts became unavailable and existing orders now have spec bump because the new factory can't get 256 MB RAM chips that work with the design, they need to use 512 MB now.

feedmegin posted:HDTVs are a) cheap these days (because all TVs are HD) and b) already in a lot of people's homes, even people who don't own computers (or don't want to let Junior use them), so effectively free. At that point your 'all that' is a $5 mouse and a $5 keyboard, which is pretty trivial compared to a computer. Having your kid tie up your TV set rather than your computer isn't much better really, and of course the set of people of [has no home computer] AND [buys a raspberry pi] is null. Not to say that's argument against getting one, but it's not really convenient. DNova posted:kids aren't allowed to take the school's computers home with them usually. it's nice to let them have more than 30 minutes three times a week (or whatever schedule) to work, don't you think? If you trust kids with a bare circuit board computer to not mess it up, well that's pretty silly. You'd also be relying on them having everything else needed to use it at home (compatible display, input devices, and being allowed to use all them). Tons of people still don't have TVs at home that accept HDMI, and composite SD video is pretty drat crappy for coding and use, especially if this thing can't autodetect when on composite output to adjust display. If your goal is to have something that students can take home to program on, a netbook or laptop would be far better, since it's more durable and you'll know they'll have the proper input/output.

DNova posted:Yes, you can trust kids with bare circuit boards to not mess it up. Some hamfists will gently caress it up but most won't. See also: musical instruments, cameras, laptops, etc. About 70% of Americans have HDTVs. Not all of those have HDMI in, many are older and don't have it. That's 30% or more of your potential students who may be stuck on composite displays. So that's going to be a problem if you're going to have them write graphical programs since 480i is going to require compromises to display things well. And maybe you've forgotten but programming on 480i composite displays was annoying as hell back then and still is today, if you want the text to be clear when you're doing it you're talking 40 column 20 something line displays, and that's going to be different from the programming environment on the same thing at school with real monitors. And something being "the cost of a field trip" isn't going to guarantee your students have it, you simply can't rely on their parents buying it. Noone's inventing problems for an education environment here, if you're saying these are good to have students take home, that's pretty much just wrong since they don't have everything you need built in. Colonel Sanders posted:I see somebody failed logic class. A lot of families have more than one TV, most kids these days have their own TV. The raspberry pi is not for families who lack a PC, it's for families who don't want to gently caress up their only PC because their kid's python program had an "undocumented feature". If only there were languagues that ran in some kind of virtual machine... too bad noone invented those and implemented them in popular school programming curricula. You don't program on an SNES or Wii. All devices running on composite video are bad for displaying a lot of text clearly, you don't need to wait to see for that because composite video hasn't changed over the past decades. Well the raspberry pi isn't a viable replacement precisely because it's not a standalone device - if you give students a netbook or laptop you know they'll definitely be able to use the screen and type on it. You can't just go "this is cheaper" and expect it to work out. Nintendo Kid fucked around with this message at 23:39 on Mar 5, 2012 |

Who said they have no televisions? I said tons of kids won't be able to use them on the TVs they have, and newsflash: non-spergs don't just buy extra mice and keyboards around the house. You simply can't expect all your students to have everything they need to use one of these at home - that's why it's a poo poo idea to recommend them for take-home programming stuff. It's really stupid that you expect that every student would have everything needed to actually use one of these at home.

DNova posted:I said sports, not gym class. Those are different things, you see. Where I grew up (lower-middle class at best), sports all cost quite a lot to join. Learning an instrument, you could RENT the school's crappy stuff every year or buy your own. Again, not cheap. And every year I remember my parents shelling out at least $40-100 on field trips, most of which were totally worthless, not to mention random required garbage (plastic recorders, books, etc). You're specifically saying these would be part of a programming class: that is the same as gym, not after school sports. You don't have to pay poo poo to play a sport in gym class. And ok so you've finally realized that people might not be able to afford things for a class, but don't get that that's bad. Saying keyboards and mice are cheap is pointless: that doesn't mean everyone can afford them. Like you seem to think that "cheap" ="everyone can buy it". It's out of touch and nerdy to expect everyone to have a television that the kid will be able and allowed to use for this, and also the other necessary equipment.

DNova posted:I have no idea how it would be set up in schools, but here, gym was mandatory for graduation. We had choices in what "specialized" classes to take, as long as you met all the requirements (it's been a while and I don't remember the specifics). The way I'm assuming "programming class" (hopefully it'd be a little more generic computer science with some applications) would be one of these types of electives. So you actually want programming classes to start costing money, so that students will have to take home something that they may not be able to use? What's wrong with doing what schools with programming classes do now where you are given access to what you need for it for free? You actually think there's no such thing as poor people in any school with a programming class? Are you high? What are you trying to imply, that anyone who can't afford buying extra stuff for their kid smokes too much?

Cockmaster posted:Could the GPIO pins be used to emulate a parallel port? I was thinking that the Raspberry Pi could make a cool CNC controller. It's cheap enough that you could just hardwire it permanently into the machine and set it up to boot directly into the CNC software, just like in an industrial machine. This could be possible, but I'd be wary of relying on it. Not because there's anything wrong with the idea but because it's a pain in general to get accurate/stable parallel port emulation set up.

All the parallel port interface does is give you a convenient point to hook up the motor drivers and stuff (and in some cases optically isolate the computer from the motors). You're not really getting anything out of emulating the parallel port specifically then! If the system you're interacting with does not already have the parallel interface,then building one on the system and one on the rpi is just making yourself more work for no gain.

I honestly can't believe someone is saying Linux was "superior in every way" for the past 20 years without being a troll. I mean, honestly now, Linux was barely usable in 1992 and 1993. It was still not very good in 1994 through 1997. 2000 is about the earliest point you could make a claim for it being a "superior OS" to everything else around (though I wouldn't agree with that assessment personally, people can make a good case starting around then).

movax posted:I think your thread title is a very apt description. The primary difference being of course, that when the Commodore 64 came out, it was around the same level of performance/features (I THINK) as its competitors. (I was not alive in 1982). The C64 was mostly comparable in performance to the Atari 800 and the current lower end Apple IIs at launch, overall, though in certain areas each would be ahead of others. Notably at its launch, it was $595 while the Atari 800 was $899 and the Apple IIs started at $1200. IBM PC was of course available in much more capable ability, but started at $1600 for the base model that used cassette tapes and used your TV. In today's money: $1,403.73 = Commodore 64 $2,120.92 = Atari 800 $2,831.04 = Apple II+ (48k) $3,774.72 = IBM PC So, you know, "cheap" is relative for the C64. $595 was cheap for a computer, but still a lot of money, and remember that even using a Datasette cost extra - $595 just got you the c64 and no storage. Edit: Also for reference with the inflation-adjusted prices, the average PC bought in 2011 cost $405 Nintendo Kid fucked around with this message at 06:14 on Apr 5, 2012 |

JnnyThndrs posted:Yeah, and the price for the C64 dropped like a rock - I distinctly remember them at $199 or so - while the Apple prices didn't really drop that much and Atari made some weird mistakes in their lineup after the 400/800 generation. Funny thing about that - according to Commodore, the total cost of production and design on each Commodore 64 they put out in 1982 was $135 ie the retail price included $460 of pure profit. So that's why later in 1982 they started having $100 rebates if you sent them a used competitor's computer when buying a C64, and then in 1983 they were able to drop the MSRP to $200.

What you've got in the Raspberry Pi is basically a smartphone from 2009 that's had a decent pre-recorded video decoder chip put in it. Imagine a slightly overclocked G1, but with h.264 1080p video support in hardware for playback.

Social Animal posted:Oh one thing that came to mind was the whole HDMI aspect. Raspberry Pi was meant to be an inexpensive way for kids to learn programming right? The fact that you need a monitor capable of HDMI kills that inexpensive aspect for me because you can't just buy this thing and then go to a flea market for a cheap VGA monitor. I understand why they went with HDMI I think but does anyone else feel the same way I do regarding this? Like I hope the kid has a spare HDMI monitor/tv before they receive this as a gift.. It may have started out as an idea to make low cost computers for kids. But let's face it, that went out the window well before launch, it's clearly for nerds who've already been buying similar classes of devices for a while now. Not that there's anything wrong with that, really, it just is what it is. Realistically it's only useful to someone who already has at least access to another computer, and has some decent enough skills or someone they know with them to get it up and running before you can start using it. And yeah technically it has composite out so you could use it with most TVs - but of course then you just remind yourself of why people stopped using SDTV signals and connections to do computer stuff. greenman100 posted:Nope, the DVI connector can carry digital and analog, vut HDMI is digital only. There'd be no signal on those pins. To be clear, you can still get an HDMI to VGA adapter, it'll just need to be active and thus cost a decent amount of money, more than the RPi itself.

Something like 800x480, and then see whether the browser performance is able to stack up. It is after all, the relative performance capability of a smartphone from 2009 or so, and then being used to handle stuff at higher res such as 1280x720 or 1920x1080. You may see performance improved by knocking down to a smartphone resolution.

syphon posted:In case anyone is interested, I got Zoneminder working. My take from it is that Raspberry Pi is not very good with cameras. Many of those webcams offload the processing for high-resolution video to the CPU, with the expectation that you'll have them plugged into a modern dual or quad core computer so the processing won't make a difference to the user. Now, given that the Pi has a single very slow core compared to any recent desktop, this causes problems trying to go above very small video feeds on the Pi with it. If you want to use a webcam, you're going to need to track down which cameras handle all the processing stuff onboard, instead of offloading it to a CPU.

Toast Museum posted:How widespread is CEC support? I've got a cheap Dynex from three or four years ago, so it wouldn't surprise me much if I were out of luck. It's almost reached the point that most new TVs have it, though not quite all, but the further you go back in the years the more it becomes a "premium brand, higher end model" thing. I have a Samsung 720p LED backlit 32 inch TV from I think 2008 or 2009 that has it (and it works great), a 42 inch 2011 model year Samsung midrange set that is it, but the cheapy VIZIO set I got in 2010 as well didn't have it. You might want to look around in the TV's manual to see if CEC is mentioned. Also some manufcacturers have a branded name they use for CEC, here's some of them: Anynet+ (Samsung); Aquos Link (Sharp); BRAVIA Link and BRAVIA Sync (Sony); E-link (AOC); Kuro Link (Pioneer); CE-Link and Regza Link (Toshiba); RIHD (Remote Interactive over HDMI) (Onkyo); RuncoLink (Runco International); SimpLink (LG); HDAVI Control, EZ-Sync, VIERA Link (Panasonic); EasyLink (Philips); and NetCommand for HDMI (Mitsubishi).
