I can't remember anymore if I've spammed this thread with my gushing enthusiasm for Alpine, but I just switched over to it from Ubuntu, and I'm a big fan. It allows you to run the entire OS out of RAM, and is quite lean on what services it starts by default. I use runit, which has built-in "log rotation" that only eats a few KB, but I would expect the default syslogd to work similarly. It does have a persistence mechanism, but you have to tell it "now commit my changes to storage". If you forget to do that, too bad, you lose your /etc modifications (including what packages are installed) when you reboot. This is actually what I want: I want the system to only write to the card when I tell it to. If you think you're running out of storage, or are worried about too many writes to the SD card, I encourage you to look into Alpine.

Pham Nuwen posted:Anyone know of speech recognition software which is light enough to run on a Pi 3 (512MB of memory)? I'm just looking to do a modest set of pre-programmed commands, with one of them being "ship whatever I say next up to a more advanced speech recognition API, if we have network". I used to work on something like this in my last job, on a Pi no less for prototyping - basically custom audio software hooked into something like Amazon Alexa. You might have some luck googling 'wake word detector' which does exactly this - recognises a few set phrases (like, say, 'Alexa') at which point you can stream whatever you hear after that to the cloud service of your choice. Edit: I know we looked at https://pimylifeup.com/raspberry-pi-porcupine/

How big a pain is it to add the libraries to get pi functions working, like the camera or messing with gpio? That's mainly why I stick with rpi's ubuntu, all that stuff comes pre-configured. I haven't corrupted an sd card in a long time either because I'm pretty careful about writing to the sd.

I've never messed with GPIO or camera on a RPi, but I'm pretty sure you just read/write to a memory-mapped location (after doing some trick to set things up, possibly mapping an interrupt condition), right? I'd think that would be part of the kernel, and the rest is libraries to make it easier to interface with. So, there's a Python3 GPIO package: https://pkgs.alpinelinux.org/package/edge/community/armhf/py3-rpigpio There's this thing that looks like a C library: https://pkgs.alpinelinux.org/package/edge/testing/armv7/pigpio There are Camera and GPIO sections on their wiki: https://archlinuxarm.org/wiki/Raspberry_Pi Are these what you're looking for, or is it more like you want specific apps?

No, I know how to do it. I was just curious how well the OS accommodates it. I've used alpine in other workloads so it's mostly a question of whether the appropriate packages exist or not.. which it appears they do so that's cool. I might try it out next time I'm doing a build.

Finally got a chance to get this out a bit more and do some more testing. Sadly, it is not, in fact, bulked out logs. I had it running with htop up, and happened to catch it as it froze. Right before it locked up, the second core of the processor just spiked to 100% (and only the second core  ) Camera stream frozen. Monitor display frozen. Welp...To make this spicier, I also happened to have been remoted into it via VNC. The core spike only lasted about 10 - 15 seconds. After it goes back to normal, I was able to still control the Pi remotely, but the stream and the pi's monitor remained frozen. And it didn't seem to be lagging at all through VNC. As if something causes the processor to have an aneurism and lose its ability to display poo poo but still do work. >_>

I have this vague recollection of running into a similar issue trying to use the old (documented) API for hardware H.264 encoding. It took me a couple days to pick apart how to use the new (undocumented) one, but then it stopped freezing. Can you find a thing that uses the new one and still does what you need?

Does anyone have a recommended application to test SD cards, or at the point where one is a few years old and has ever done anything iffy should I throw them away? This is for more than just Pis, for better or worse I've got a lot of SD cards in a lot of different devices. Also, is the official case the best way to cool a 5? How do they hold up with just a passive heatsink on there instead of a fan? Is there any way to throttle down target power instead? I want to use a 5 as a (toy) ARM CI server, comparing it to cross compiling + QEMU emulation on x86. If heat throttling just makes it slower without any wear or damage concerns, I'd be happy just to let it throttle.

the official case is just a plastic heat trap so it's not great, especially if you aren't running active cooling there's some beefy passive heatsink cases which can soak a lot of watts https://www.tomshardware.com/raspberry-pi/raspberry-pi-cases/edatec-raspberry-pi-5-cases-review-passively-cool

I wonder if there is a market for something similar to the Pi with a higher targeted performance. That is covered by the Beelink and so on but I’m thinking something more standardized. I had hoped that’s what the initial stab at Steam Machine/SteamPS would have done but eh. I suppose their failure is likely the answer to my question.

NUC motherboards are 4" square except for the weird variants with upgraded IGP/PCIe graphics support. Past that you're looking at the "Tiny/Mini/Micro" style PCs which seem to be popular enough and fairly standard proportions within a given OEM.

The reason the Pi is so popular is the effort that they put into making software work properly on it rather than shipping a bag of parts and going "lol you figure it out". If someone else decides to care about distro support on their small tinkering SBC then the Pi has almost no value.

While you’d want something of a fairly standard form factor I’m more mentally picturing something taking a similar approach to the iPad where you get a newer better version every few years that allows for better sorcerer support as you’re limiting potential deltas.

Got my pi 5. I plug my Nintendo switch usb-c power supply in and I get an error from the pi OS that this is not a 5 amp charger and that power to accessories might be diminished Fair enough. I plug the Pi 5 into my MacBook Pro power supply which shows 5A on the plastic case and I still see the same 5A error. https://www.raspberrypi.com/documentation/computers/raspberry-pi-5.html#powering-raspberry-pi-5 quote:It’s not possible to use older USB "dumb" cables and connectors to provide more than 15W, even with a USB-PD capable supply. Apparently I’m just using the wrong cables and should have gotten their official power supply. I wonder if performance is degraded in 3A vs 5A

You more or less have to use the Pi charger they sell as the 5 uses a nonstandard (it is a standard, but no one actually uses it iirc) PowerDelivery spec. You haven’t really been able to just plug whatever into a Pi since I want to say the 3.

Coffee Jones posted:I wonder if performance is degraded in 3A vs 5A No. You just can't pass extra power to things plugged into the USB ports on the Pi. If you aren't using high-power USB devices, there is zero need for the special 5A official supply.
