Is the wifi on the pi3 a bit buggy ? I've been seeing some odd behaviour with very inconsistently being able to ping the pi3 even with full signal strength. I've tried a wifi usb adapter and all the problems went away. Same router, TCP settings etc.

If I wanted to control a blind with a raspberry pi and a remote, how would I do that? What I have in mind is this, demo at 3:34 https://www.youtube.com/watch?v=uuGU1J3c1Pw Ideally i'd love to have an interface where I can hit a screen proportion, and BAM it does it! Realistically I will probably have a wired connection like his. But I dare to dream!

How do you imagine your remote looking like? If you want something custom it'll be more work. With a (TV-style) prebuilt remote and a motor driver it'd be pretty simple, just not as sleek.

If you have a harmony already I'd just use that and a cheap IR receiver. Then get one of the million linear actuators on eBay (with limit switches) and a driver to make it move. There's tutorials online for all of this. Motor drivers are stupid cheap on eBay too.

Are there any decently priced NAS boxes with BusyBox or Linux support to scratch the cheap server itch? These smartphone chipsets on a board always have more GPU and less hard drive and networking support than you'd want for that. Ideally, rather than being a prebuilt system with manufacturer sanctioned apps (like the Western Digital Personal Cloud stuff), it'd just give you an SSH shell to configure as you'd like.

What's your price point, feature set, etc? You could go anywhere from a simple fully integrated fanless x86 motherboard with last year's tech for $80, all the way down to a TP-Link TL-WR703N running openwrt for $25 shipped.

It looks like a bunch of the things in the Wikipedia list of single-board computers[1] have SATA. If any of those have more than one port (or proper support for SATA port switching) and Gbit networking , you could probably build something? [1] https://en.m.wikipedia.org/wiki/Comparison_of_single-board_computers Practically speaking, a mini-itx PC would be faster, easier, and can be had with way more SATA connectors ... but they are also larger, more expensive, and use more power. Besides, where's the challenge in that.  Comedy option: buy an old large thinkpad with a dead screen. Stuff two large 2.5" drives in it and you have a decent quiet NAS with built-in UPS.

This was my first dedicated file server, except I had two bus powered external USB hard drives attached. Then I realized that's a terrible idea and bought a $100, 15 drive (capacity) case with an Intel motherboard, so I only have to solve this problem once, and simply add/swap drives as needed. As a hobbyist experiment, the Pi is great for doing NAS. Trying to do actual long term home file storage, $100 worth of last year's low end hardware is the right way to do home NAS.

Yeah any old board by now will take an ultra cheap 8 port Intel sata adapter, and off you go.

Amberskin posted:According to the Raspberry Foundation announcement, the OS is still 32 bit (actually, the same being used for the Rpi2) and they are checking if moving to 64 bit boosts the performance enought to be worth the effort. If Linux had a sane multi-architecture binary system like NeXT and Apple have used since the 1990s, this wouldn't be a big deal. In fact, if they had proper multi-arch binaries, they could build Raspbian for armv6 and armv7 for the RPi2, and still allow armv6 binaries to run on the RPi2 as well. Just like iOS has since before the original RPi shipped. And they could support armv6, armv7, and arm64 binaries on the RPi3, again like iOS has since the iPhone 5s shipped over two years ago. And that wouldn't even require a 64-bit kernel, because with a proper OS whether you use a 32-bit or 64-bit kernel is independent of whether user processes can be 32-bit or 64-bit. Then again, I'm also the person who thinks a single distro image should be able to boot on any number of SBCs, just by adding device drivers and standardizing the booter/kernel handoff.

You could get a used Sun T5240 with tens (or more!) GB of RAM for about US$400 and slap a couple of 2.5in SAS drives in it. It'll run the latest Solaris, which you can get free from Oracle, which can either be a hardcore file server or managed iSCSI target. You'll need a rack and to not mind the noise & heat. Oh, and 200V power if you get anything larger than the 8-bay model. But you could conceivably get close to wire speed when streaming lots of data on gigabit Ethernet, for a few hundred bucks plus the cost of however many drives you want to put in it.

Even if something like FatELF were to become standard I doubt arm architectures would be a common target with most binaries. Even with OSX, multi-arch binaries don't have to be compile for all architectures if you don't want to.

Our department file server is a 7 year old dell workstation with 4 drives on the internal controller and two external 4-drive boxes hanging off a cheap Marvell eSATA card. 16 GB RAM, WD red drives, ZFS, FreeBSD. More than enough for wire speed reads, and it was enough for writes as well until it filled to 95%. (I'm finally prepping a new proper replacement for it, yes. Something about 25TB of research data on hardware that was a bit iffy several years ago mildly worries me.) Computer viking fucked around with this message at 22:32 on Mar 2, 2016 |

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.

A J1800 Baytrail mobo inside an ancient tower case has served me well as a home server the last 2 years+. Pros: fanless, very low power, can deliver 1080 video using Plex at about 80% CPU load in Linux. Cons: only 2 SATA ports. I'd imagine the newer Braswell ones have a bit more oomph in the CPU department.

I wonder if i can get some help from the rest of you, I am into IT, have been a developer for way too many years than i care to mention (I started with zx81) I just see a Pi as a PC running linux. I have a PiFace and 2 Pi-B and one Pi2 I also have a breadboard kit with the header cable for the Pi as well. I have yet to find any helpful information on how to enable piface or do anything interesting except a "weather station". I live in the UK so the weather is NOT at the top of my targets of projects. Maybe there is some good links that can help computer based people like me get into the "engineering" side rather than the Engineers getting into programming.... links if possible please.

I have the obligatory webcam, I also have the 'night vision' cam which is on my list to do something with, got a few small OLED displays, which are interesting to get installed and working, then quite fun to script, I've learnt quite a bit of Python doing stuff like this. Theres also the 'solder kit' stuff - the power switch, breakout board and so on - keeps me entertained in my spare time. Basically, I am a sucker for the adafruit style projects - tiny touch screens, breakout boards etc - https://www.pi-supply.com is a good place to browse. got my Pi3 yesterday, haven't had chance to try it yet though.

How well does the ras 3 work as replacement desktop for web browsing, word processing, light image/video editing, online streaming media (youtube, spotify, netflix)? I'm okay with debian and looking to get one and set it up for my father to use as a PC.

I'm okay with debian and looking to get one and set it up for my father to use as a PC. It's going to be awful for video editing because of the limited data bandwidth and slow poo poo GPU. That stuff will also be bad for image editing if we're talking 10 megapixel plus photos. You should probably pick him up a couple years old laptop and stick it on a cooling pad, with a monitor and keyboard/mouse running to it - they'll be around $150-$200 for a nice Sandy Bridge system from 2011 which handle all of that flawlessly. Here's a good example, the case is beat up but who cares? It's not going to be moving: http://www.ebay.com/itm/Lenovo-Thin...tEAAOSwYlJW2HmX

Even for web browsing it will be slow as gently caress because 1GB RAM is not enough RAM for today's memory hungry desktop applications. I tried the new Chromium OS port, and it is still crazy slow. The entire OS is stripped of everything not needed for running a browser, and it is still uselessly slow. And Netflix and other paid streaming services are going to be somewhere between a headache and completely unavailable.

Yeah my rule of thumb is never recommend non-brandname stuff to family members unless they're tech savvy. I tell my brother to build his own stuff and give him parts recommendations, I tell my parents & grandparents & not-nerdo friends what brands to look at. The Pi really, really isn't meant to be a desktop replacement, it's a learning tool and hobbyist item and even with the processor upgrade I can't see it being a passable solution for anyone expecting a computer to 'just work'.

The only way to use the Pi 2 as a Desktop computer is with very lightweight apps. If you don't even start up X and just do stuff with console-based applications like emacs etc.. it's quite usable as a typewriter but I don't think that's for Dads. As fishmech posted, your father will be served much better with an cheap x86 based product. These tiny ARM SBCs simply aren't there yet.

I'm hoping someone can point me in the right direction here. I just received the official touchscreen display, and I'm trying to understand it's interface. I realized today that even though the touchscreen works, I never enabled i2c in my boot config. Some sparse info points out that the GPU is in charge of that particular i2c interface (on the display and camera connectors), so I actually have no idea how Linux is utilizing this touchscreen. Anyone know where I might start looking? Aside from this---the display seems to be pretty decent, even if they made the goddamn rookie mistake of making the display orientation upside-dow. The viewing angle isnt symmetric, so it has a preferred orientation and unless you have it mounted on something in a pretty ugly way (since it is only really equipped to be mounted on the back, and not flush mounted into an enclosure) the USB power cable would need to come in from the bottom in order to use the correct orientation. While this isn't an uncommon mistake (my team at work ran into that same issue last year, but corrected it in the 2nd revision prototype), it's kinda weird that they didn't catch it before their design went through EMC testing. I guess it's not high enough volume to merit them fixing it with a display interface board revision since that would require another round of EMC testing, which isn't cheap
