Hm, there really is no way to just throw NOOBS onto a Pi, connect it to a router and just SSH into it. I pretty much have to attach a monitor and keyboard just to activate SSH. Kind of annoying. edit: NOOBS is not Raspbian, I'm a dumb head. doctorfrog fucked around with this message at 18:35 on Jul 28, 2015 |

You can get a Raspbian image from here (scroll down past NOOBS): https://www.raspberrypi.org/downloads/

What does NOOBS do for the average user if you're installing Raspian? It looks like if you flash NOOBS on there and then choose Raspian as your default install you still have to use the colorized text installer anyways.

It would be even nicer if it had some SSH and command line support on the installer, so I could headlessly install one of the alternative OS's, but it's still pretty nice to have. Unless that's something else I'm missing. Also would be nice to have a bonehead-safe command-line-configurable wireless utility without having to run the desktop... All told I'm still pretty impressed with how easy and fun it is to set up this little Linux box for someone who isn't that familiar with it outside some halfhearted desktop use.

Yeah it's been thoroughly proven that the odroid c3 is crazy faster for that sort of thing. There are a couple of similar boards that actually have sata ports on the board which ought to improve speeds considerably. The pi is just about the worst platform to do network file sharing and it's extremely gimped in that regard.

The problem with using it for networked file sharing is that the system drive (SD card), file drives, and the network all hang off a single USB 2.0 channel. So yeah it tends to be pretty crap for that application. At this point there's a lot of competitors at similar price-ranges that produce better products. For the same money you can get some combination of more memory, faster cores, gigabit, onboard wifi, etc. Competitive models with USB 3.0 are creeping down in price, and they dominate the Pi in many tasks because it's effectively a 10x jump in the speed of the system bus. It's not impossible to bottleneck a 5 Gbit/s bus, but it's far more difficult than bottlenecking a 400 MBit/s bus. And booksize PCs with much faster x86 processors and much better system architecture keep creeping downwards in price as well. I also have a hard time taking the "long-term-support hardware/software" and "bigger software catalog" things seriously. Odroid or BeagleBone Black do just as well and in some cases better. In particular it took 2 years for the Pi folks to fix a bug in their drivers that caused USB frame dropping when operated at 2.0 speeds, which is pretty nuts for a device that uses USB as a system bus. Also they will always have a penchant for burning up SD cards, which is a real pain for a device that's supposed to be stable and supported for educational use/etc. You shouldn't have to do a wonky bootstrap on SD then bounce to a root filesystem kept on a separate USB device in order to not destroy your disks in casual usage. Spending an extra $10 on a BBB gets you bootable onboard eMMC. eMMC ain't perfect but it's much better at wear leveling than an SD card. Over a year's timeframe of casually poking at Linux Stuff my Pi crapped 2 SD cards, whereas my booksize media PC running on eMMC has been rock solid. Most people would really be better off working a couple more hours and putting the extra cash towards a BeagleBone Black or a Liva or something. You will spend more than the difference in nickel-and-dime'ing for SD cards, USB sticks, wifi adapters, codec licenses, time and money spent hunting for a power supply that's stable enough, rebuilding your system when the SD cards crap out, etc. In comparison I took my booksize PC out of the box, plugged in the included power supply, boom it's booted off the OS preloaded on the included eMMC, connected to my wifi, and it's been running nonstop ever since. BBB also includes a Debian preload too. Paul MaudDib fucked around with this message at 18:04 on Jul 29, 2015 |

Yeah I get that you can technically do file sharing on the Pi, but the fact that everything goes over the same bus really does cripple it. It's not like a '63 beetle, for file sharing specifically it's more like a Razr scooter modified with a 2-stroke gas weed whacker engine bolted on, and driving the rear wheel with rubber bands. The odroid c3 has everything correctly setup. And yeah the Beaglebone black is basically the motherboard from a chromebook and crazy fast for those kinds of applications compared to the Pi.

I see. Well, if it's something I will be using long-term, I'll look into those other computer things. Something that ran off of an SD card and a flash drive was never going to be a permanent thing. edit: I'll repeat that my original use case was to just upload and download some files to my phone/laptop on an infrequent basis, not as a robust file sharing platform. doctorfrog fucked around with this message at 22:19 on Jul 29, 2015 |

They also still aren't on a mainline Linux kernel yet (but are really close from what I hear), so you're stuck with an ancient 3.8 kernel by default or a more modern 4.x kernel with some broken stuff. The Pi is on a mainline 3.19 kernel which is much more modern and has better driver support. Getting wifi to work with the BBB is also a bit of a pain since the kernel is old and there's a known issue with interference from the ground plane below the USB port if you use the short little stubby USB wifi adapters (the workaround the BBB designer suggests is using a small 3" or so USB cable extension). The eMMC memory is nice but it's only 4GB which gets used up very quickly.

Does anyone know what the latency is for Pulseaudio audio streaming? I have a Chromebox running Arch and I have a Pi B that I'd like to set up a Spotify audio sink to. The goal is to stream over the network and play it on my stereo using the 3.5mm jack. I achieved a setup similar to this before using Rygel and tapping into that using OpenElec, but the stream was nearly 30 seconds behind whatever I for the stream. Should I expect similar results to the old setup? I've tried Volumio and it's not quite what I want, it's Spotify integration is actually quite poo poo and consists solely of "play this Platlist". Most often I just play a Youtube mixtape.

The eMMC memory is nice but it's only 4GB which gets used up very quickly. OK, good to know. I was just going on reputation and what I could pull off the spec sheets  I replaced both the roles I tried to use Pis for with low-power x86 machines instead. I ended up getting a Zotac Zbox BI320 as a media PC. For $160 it came with a Haswell 2957U with iGPU, 2GB of memory (2 sockets), a 64 GB eMMC drive, and it's got a real SATA port for a 2.5" drive in case I ever feel the need for local storage or a SSD. It's not overpowered but it does fine running Kodi with 1080p playback, streaming, etc. Installing Windows updates was a bitch though, took about a week to get them all installed. Pulls about 5W idle and 15W loaded. I definitely wouldn't mind picking up another one, just haven't seen that price again. I grabbed an Athlon 5350 as a fileserver. It runs ye olde SMB share, SABnzbd, Sonarr, Couchpotato, Seafile, my Git repo, that kind of thing. I'm gonna throw Jetty+Postgres and Jenkins on it for dev work and OpenVPN too one of these days too. You can pick up AM1 boards in bundles pretty often at Fry's for $40-60 (usually with the lower-tier 5150 or the Semprons), which I think is a pretty good deal. The J1800/1900/2xxx offer similar performance and can often be found in a similar price range. They do lack AES-NI which can increase CPU utilization when working with SSL, so that may be a consideration if that's a big part of your workload. Put it in that cheap Rosewill case and throw in a 4GB stick of memory and you're ready to roll. It's massively faster than a Pi at any one task and I can do multiple things in parallel. It's not a speed demon versus a real desktop processor but I never really feel like it's unacceptably slow either. Also, I can use standard x64 binaries. Pulls about 25-30W all up if I remember. My only complaint is that USB 3.0 doesn't work at all on my mobo, some kernel problem that I'm too  to debug. I should try 15.04 now that it's out and see if that helps, but that would also be I've always been curious about the Parallela and the Jetson TK1, just haven't actually gone out and bought one. If NVIDIA ever released an updated Jetson with a Tegra X1 on it I'd jump at the chance. The Odroid XU4 looks pretty sweet too actually - 2 Ghz octa-core, 1GigE, and USB 3.0 in a Raspberry Pi footprint. Paul MaudDib fucked around with this message at 15:40 on Jul 30, 2015 |

It's not a Raspberry Pi, but I just ordered a DragonBoard 410c, a quad-core ARM64 SBC the size of a credit card with 1GB RAM, 8GB eMMC, Bluetooth and WiFi built in, HDMI and a decent GPU too, and micro-SD for storage. All for $75. Maybe I'll port libmraa while I hope someone works on SBCL or CCL for ARM64. Or maybe I should offer a board to someone hacking on those…

So I'm struggling on getting past the login stage of my Seafile install. I can access the login screen through its local IP address and my no-ip "cloudname".ddns.net domain, but I get a server error about a "server hiccup" and "engineers being notified". I have done two complete installs and followed this install with the only changes being the internal server name, changing the .no-ip.org references to .ddns.net and the name I used for my .ddns.net domain is obviously not the "mycloud" example. I'm not a network pro and Googling is failing. Any ideas? Edit: I also use a static ip for wifi using a wpa_supplicant file.

That's like the Beaglebone Black of 2015/16 I guess the 2014 Moto E was released with the snapdragon 410 as well but the G is probably a device most people have actually seen in the wild, let alone heard of.

I'm still fiddling with Seafile, but it's way overpowered for what I need it for anyway (just hosting some jpegs and mp3s and documents for my personal use, plus the ability to upload/download). It's pretty educational as a project, though, you couldn't have gotten me to break out my noisy hot netbook to do this kind of elaborate install routine and configuration. But a silent little box running off of a cellphone charger? Lots more fun somehow. Seafile is actually pretty attractive as a permanent thing, but rather than go after a banana board or whatever, I think I'm more likely to pick up something like an HP Stream or a NUC. Is there an in-depth list of Raspberry Pi OS's somewhere? I'm looking at maybe using PressPi to put up a Wordpress site, fiddle around with that. This is fun stuff. And of course I have a spare SD card with RetroPie on it.
