My CHIP arrived a couple weeks ago, but it had the buggy firmware that requires an ubuntu machine to flash the special fix. Oh, I just realized I could probably flash this with a raspberry pi...

Down the line, I'm looking to set up a cluster of Pi's (or CHIPs or Pi 0's) for idiot hobby distributed programming projects, am I correct in assuming that on the physical end all I need are the devices with an ethernet switch to connect them? Obviously also there'd be an enclosure and power supplies, but I guess the set up would be a head that communicates between the outside world and the rest of the cluster. I've played with clusters on the software end, but never actually built one.

Just needs emmc onboard storage and priced under $30 and you've got a pretty spiffy IoT platform. They've needed onboard wifi for at least two years now, glad to see that is standard. Is the total lack of availability for the first 8 months a marketing thing or is manufacturing capability in the UK just really bad? 64 bit quad core is reeeeally interesting, that will make it 100% docker compatible. Docker containers can technically be 32 bit, but there's no formal support for 32 bit containers, they standardized on 64 bit a long time ago. Someone will come out with a base Heroku/Dokku base image soon for the RPi3 and you'll be able to spin up your Postgres, Kodi, Ember and Bittorrent containers with the click of a mouse, let it all autoconfigure and boom. On this new chip, does the SD card live on it's own seperate bus, or does it still eat up major bandwith from the USB ports, crippling external USB storage (again)?

One of the memory benchmarks seems to indicate that at least the bandwidth to main memory is much better, despite there being no memory speed difference from the Pi to Pi 2 to Pi 3. I wouldn't hold out much hope though, the Pi 3 doesn't even have an updated GPU relative to the original Pi. Only the CPU itself is improved, and they're talking about "maybe" shipping a 64-bit build of Raspbian. Hopefully Linux on ARM will finally start to standardize a bit, so in maybe a year or three only a bootstrap and driver set are actually needed for any particular board rather than a full distribution. I expect BSD will get there first since NetBSD is already kind of in that position.

It's just the stupider ARM cores that require a ton of work, and mostly because packages aren't built with the right flags. uboot is a mess in any case, but aarch64 is EFI, so there's still hope. floor is lava posted:The prebuilt image smartass.

floor is lava posted:I wonder how long it'll take for retropie to be ported over. Retropie's current image should work fine and see a bit of a performance boost from the 1.2ghz cores. Although the Pi 3 CPU is 64 bit, if you read the raspberrypi.org blog post it says Raspbian doesn't support 64-bit and they're looking at enabling it in the future. For now the same old 32 bit Raspbian code will run fine on the Pi 3. They explicitly made the new CPU peripherals backwards compatible with the older Pi's too so there shouldn't be any code changes necessary to access GPIO, etc.

The CPU seems to be quite a bit faster from benchmarks shown, how well that translates into real-world performance remains to be seen I guess, but I'm pretty sure it's noticeable. I'm currently still quite happy with my Pi 2. The "10x faster" is in relation to the first Pi though and I honestly find it a bit of a cheap shot to use that wording, the performance difference to the Pi 2 is about 50-60% faster. (as per their word) The Pi was often compared to the C64 and such in it's early days, kinda takes you back to the old days too when there's a new one coming out that makes the old one clearly obsolete every few months, doesn't it? At least this time around it doesn't sting as much financially. So how many of you just bought a Pi 2?

Unfortunately they still have the bandwidth issue with the USB and Ethernet sharing a hub.  Appears that they're still using the same GPU as well. Any guesses as to whether or not this version would be capable of running Android? Video acceleration was the issue last time I saw the topic discussed. Has the one developer they hired manage to get drivers up and running?

How would I go about creating a rpi that boots up a word processor and nothing else? No visible operating system or other programs. Like a console for a word processor. Could I get away with using the CHIPS thing instead? All it needs to do is process unformatted text and save it, maybe allow for export by bluetooth?

You could try clearing out your xinit.rc and just running the word processor straight from there so that it fires up as soon as X is started. This is what I've been doing for something similar, but that also has GUI options for logoff, shutdown et. al. Naked Bear fucked around with this message at 23:56 on Feb 29, 2016 |

The Pi Model B+ was better, and the Pi 2 launch was exceptionally smooth, shipping 500,000 in two weeks. The launch of a Pi Zero was an aberration, due to unexpected demand and low-ish manufacturing quantities. There were only 100,000 units manufactured in the first run of Pi Zeros, with another 100,000 following shortly thereafter. Right now, there are 300,000 Pi 3s sitting in warehouses, ready to be shipped out around the world. So the waitlist will be 1/3 as bad as the Zero, probably less because I can't foresee as much demand for the 3, because $35 isn't the same price as your vanilla soy latte every morning.

Could I get away with using the CHIPS thing instead? All it needs to do is process unformatted text and save it, maybe allow for export by bluetooth? The ultimate stripped down way to do it is by replacing /init with a shell script. You'll probably end up in 80x24 text mode but for your purposes that could work. This may be more complicated if they're using systemd; I have some tricks to deal with it but basically systemd has subsumed udev so your disks aren't gonna show up IIRC Edit: if none of this made sense, do what the other poster suggested and look up a guide on setting up your xinitrc file. If you have it start a tiling window manager like xmonad too, it'll automatically full screen your writing program without taking up any additional screen space.

You know, I'm actually a tad annoyed seeing the specs of the rpi3 today after having read this article go on and on about the CPU and how it would make it a "real desktop computer". The rpi2's CPU upgrade didn't make a whole lot of difference because CPU wasn't the bottleneck for much of anything you could do on the rpi1, so how is an even smaller performance jump supposed to change things? It still won't decode H265, run android, or play video in a browser window because they are too attached to the "open" GPU which isn't, and it won't be a useful fileserver, router or do much of anything requiring decent IO throughput because everything is still sitting on a single USB2 bus and it just doesn't cut it. I actually tried running a whole bunch of stuff on my rpi2 when I first got it (to see what it was capable of), and I will list the improvements that I noticed:

I wonder if openvpn would see any improvement since the Pi 3 has an armv8 CPU. There are quite a few people using them for torrenting in combination with a VPN and that'd be quite interesting. I think the upsides of a Pi are that it uses very, very little power (sadly very relevant in some countries ) and room and yet still can run linux, I wouldn't get one for performance or as fully fledged Desktop and they're still quite far away from that. I also do not think they're great for "trying out linux" actually quite the contrary, you'll probably get out a lot more of them if you already know quite a bit about linux. There are these ARM SBCs with SATA and Gigabit Ethernet, how well do they handle themselves in real situations that actually cause significant traffic? I'd imagine more cpu bound stuff would choke the CPU out long before the bandwidth is saturated. Anyone has any good links or even a thread on these cheap ARM-based SBCs with reviews and stuff? I find the SNR-ratio regarding them to be terrible.

The last time I tried to use a Raspberry Pi 2 as a desktop machine, web browsing was sloooooow, even compared to a ten year old Core 2 Duo machine. A 50% speed increase and no extra RAM isn't going to fix that. Youtube barely worked, and there is also no support (as far as I can tell) for Netflix or any of the other paid video streaming outlets. Working youtube for things like Khan Academy seems like it should be a pretty high priority for a company trying to sell simple computers for education.

Browsing is in it's own league regarding desktop usage anyways, that's where all the lower powered machines fall flat somewhere, also a bit depending on your browsing habits. Of course it's an important thing a modern desktop should be able to do.
