MrQwerty posted:I'm in the US and set Raspbian to US UTF8 in the language settings, this is just really strange. I mean, if I type out #include <stdio.h>, the output in nano is £include <stdio.h>, and if I type printf("gently caress my rear end why won't this work"), the output in nano is printf(@gently caress my rear end why won't this work@), and compiling just flat out isn't an option. That's almost assuredly a keyboard layout issue. Try this... http://elinux.org/RPi_Beginners#Keyboard_layout Edit: You'll need to reboot as well.

Has anyone had success moving their root fs to a usb stick? I tried a couple of tutorials but I seem to brick it at some point. I've managed to get the usb stick formatted with a copy of the install on it, but when I switch it over in fstab and cmdline.txt it won't boot any more. I'll try to post some examples of my fdisk and configuration files after this next attempt.df -h posted:pi@raspberrypi ~ $ df -h fstab on the usb stick posted:proc /proc proc defaults 0 0 cmdline.txt on sdcard posted:dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait ItBurns fucked around with this message at 03:24 on Mar 8, 2014 |

PS. Love the cabin posted:From a quick glance your cmdline.txt still has root=/dev/mmcblk0p2, also your usb stick would be /dev/sda(part #) so if it's on the first partition it'd be /dev/sda1. Ah yeah, that's from a fresh install. I had it set to /dev/sda1p1, which is the only partition on the usb drive and has the copy of the fs from the sd card. Edit: Changing it to root=/dev/sda1p1 gives me this...

PS. Love the cabin posted:Unless something changed in the last few kernel versions you don't access partitions like that for USB sticks and things like HDDs. Changing it to /dev/sda1 fixed the booting problem. I have some errors about the file system, but hopefully I can work those out. Thanks!

Amberskin posted:You should get firmware updates via the raspbian repositories if I'm not wrong. I have got at least one (and it broke my setup because I didn't had the /boot partition mounted, so it dropped its stuff into the /boot directory of my root HD). That sucks. Would adding the mmcblk0p1 partition back to fstab as /boot prevent this?

How do the small 8-core atom boards stack up against older/similarly priced server hardware? The 2758 and 2750 are two models IIRC. I would imagine that they fall short in terms of total CPU power.

Cockmaster posted:I've been looking into getting into computer vision for robotics. Do you suppose the Pi Model 3 would have the power to calculate a stereo depth map from a pair of cameras? I'd probably be using only 640x480 resolution for each camera, but I'd need it to reliably handle a good framerate (ideally 90Hz). 20th Edit after some more research... It looks like the Broadcom VideoCore IV in the Pi works with OpenCV now that they've opened up the source. I guess the real question is whether it's going to be worth it to pay more for a more powerful GPU because you're not going to get 90hz out of the Pi. Some quick searching turned up some projects that used the RPi for exactly this problem though. ItBurns fucked around with this message at 05:37 on Mar 17, 2016 |

Cockmaster posted:Well, I might not need 90Hz if I can get good range (my intent was to bolt it to a high-performance R/C truck and have it avoid obstacles at 30-40mph), but I'd certainly need more than the 12FPS people seem to be getting. There are some Jetson development boards from Nvidia that will support CUDA and a variety of boards for mobile phone development that will give you access to higher end mobile GPUs and OpenCV. Bear in mind that most/all commercial vehicles are still using radar for this thing. Edit: Assuming that you're on roughly flat ground and are trying to avoid relatively uniform obstacles you could take a subset of the image corresponding to the likely area of travel and compress it into a single dimension via an average or some activation function. That would greatly reduce the complexity of the problem. ItBurns fucked around with this message at 20:59 on Mar 21, 2016 |

Cockmaster posted:You mean those things that are way too expensive for anyone other than well-funded robotics researchers? https://www.robotshop.com has a few small LIDAR units for under $2000, but even that's more than I was looking to spend. I was more so saying that the radar is still the best thing going for production vehicles at this point. All/most of the collision avoidance stuff is based at least in part on radar because its just way more reliable for a +/- of whether or not you're going to hit something 5' away. The $2 sensors work on the scale of inches, so I don't think they'd work.

Baconroll posted:Anyone know what performance is like when using a Raspberry Pi 1 B+ as as an OpenVPN server ? I'd only be using it for browsing/email - no streaming or intensive downloads. Any would be fine for a single user doing email and browsing, even remote desktop, but there's no reason to buy anything other than the Pi3 aside from availability. That being said, while the Pi2 and Pi3 are indeed faster than the Pi1, if you're really concerned about throughput you probably want something else entirely. There are also CPU instruction sets that make AES encryption much easier which I don't believe the Pi supports. Depending on where you're at on the 'Please don't steal my credit card' to 'I am a high ranking ISIS commander' spectrum of paranoia you might also want to consider whether it can run mainline linux (not the Pi1) as opposed to Raspbian or some custom distro downloaded from China. I'm not saying Raspbian is bad, but crazier things have happened.

If it doesn't have to be ARM there are a multitude of low-power Atom boards that might fit, although you would have to deal with a larger itx footprint rather than something the size of a playing card. Check out linuxgizmos.com. If you're building a netbook then you could also look at netbook motherboards sold as parts/replacements.

General_Failure posted:Is there a benefit to having the OS on a USB drive instead of MicroSD? Not including the rewritability of using a USB HDD. It tends to be a faster file system, but how much faster really depends on how slow your SD card is and how much you're actually being bottlenecked by IO. There's s huge amount of variation in SD cards and USB is not only faster but also more consistent as far as I've seen.
