Just a quick trip report; I did snag one of those RetroFlag cases (looks fantastic), a raspberry pi 3 B+, heatsink and fan. I loaded it up with the latest RetroPie OS and tried out the SENS emulator on my 1080p tv: A+. Runs and looks like a dream.

I heard this thread likes Raspberry Pis. So do I (well, my company):  Mix in a bit of 3D printing...  Some off-the-shelf hardware...  Assemble...  Add one (1) surplus 19" PoE switch... (sorry about the shite image quality - not much light in the server room)  And you have yourself a fairly decent 3U collection of remotely power cyclable ARM linux nodes on which you can do TOP SECRET stuff.

A shelf of pi's in my server room is the last thing I would ever want to be responsible for.

I bet it's cheaper than a rack server running a bunch of virtual machines but I'd rather have to manage a proper setup than deal with a set of Pis. You do you, though. It's probably more fun to build something like that then buy something off the shelf at least.

It's not so bad, they're compute nodes, and over provisioned, so if a couple break down it's no big deal. But server-grade they ain't.

Tell me where I can get 40 ARM cores in a nice and neat package and I'm all ears. That Chinese vaporware 24-way ARM server only counts when it's shipping.

So now I'm curious what you're doing that specifically needs an ARM CPU. edit: I'm curious because I've personally never used a Pi for something that couldn't just be run on or recompiled for any other Linux system BattleMaster fucked around with this message at 18:10 on Jan 17, 2019 |

How fast is our standard test? Is valgrind happy? We have certain optimized functions that sport ARM intrinsics, using the vectorized operations and such, which can really only be exercised on real hardware.

Neat. You do seem to have found an edge case where that makes sense. Do the new Pis with PoE get toasty enough to warp 3D printed ABS?

Things have been designed a little bit with airflow in mind and they will live in a climate controlled space, but it remains to be seen. Curious what the PoE load will be at full tilt, I think it’s somewhere in the 5W per Pi neighborhood.

What are the options for monitoring a Pi? I just have one at the moment, running Pihole and Unbound, and I ssh in from another machine and htop and all that but I was wondering if there is a more elegant, prettier way to do this?

My roommate got a PS4 so I don't need the pi to run Netflix on the TV anymore. Would Retropie run okay at the same time as pihole on a 3B+? Pihole is about the only thing I'm using it for at this point, and that seems like a waste.

Related to this, I'm trying to use hzeller's library to do the same thing with a 16x32 LED matrix. I've gotten the matrices wired up and testing via command line, and it's working just fine, but I CANNOT FOR THE LIFE OF ME figure out how to make it into a clock. I am not a linux person, and guides are all outdated (referencing older library versions that do not work anymore), or don't apply to my setup

I have a Pi 3B+ working as a pihole, and a standard Pi 3 that I was trying to get working with this LED matrix project. However! I'm thinking about making the 3 work as the pihole, and using the 3B+ as a Plex server, with USB 3 storage drives attached. I don't want it to transcode for internet streaming, more just to sling files on my network. All viewing would be done on other devices. Is that an appropriate use for it? I have a few 4k files, but most are 1080p. The drives would, of course, be powered by their own AC adapters. If so, could I also torrent on the pi itself, while streaming Plex? If so, I could retire an entire computer that's currently only doing the plex and torrenting. I also use the computer to actually consume most of the media, attached to the TV, but I was planning on picking up a Chromecast to do that instead (gently caress smart TVs in general).

Based on Google soon removing the capability for Chromium/Chrome to support Ublock thereby kneecapping the effectiveness of all adblocking extensions i finally broke down and installed PiHole on a pi 2b. It took about 15 minutes from gathering all the parts to being able to use it as DNS for my desktop ... that is by far the quickest deployment of a test system I have ever had. That includes moving it from a wifi bridge router in my office to the main switch in the basement. If anyone has been putting off doing this I definitely 100% encourage it. The admin UI is great. The only gotcha I found was that if I didn't shut it down gracefully before powering it down the pi would occasionally not come up correctly (I used 'sudo halt' via ssh).

My last hesitancy about going in on pihole is a worry that something goes wrong (Pi shuts down or something) and now my whole WiFi / network for the house is defunct for my family until I get home and resolve. It acts as the DNS server for my router right? So if it drops, bye bye internet, right?

Haven't had to use it yet, but last time I poked into any stock router firmware (I run DD-WRT), I saw that they all seem to have multiple DNS settings available. I have 8.8.8.8 and 9.9.9.9 (Quad9) as my two backups.

Oh thanks I've been meaning to ask if those two DNS settings would work the way you'd want with a Pi-Hole, falling back to the second when the Pi-Hole is down but not just using it all the time to fulfill requests for the ad servers the Pi-Hole rejects.

If you regularly go onto deal sites that have referral redirects like Slickdeals you're going to have to whitelist all of their garbage domains or go to the linked site and search for the item yourself.

Can I set up a pihole to prevent Windows 10 from ever connecting to Microsoft's servers ever again? Or block ads in mobile apps on my tablet? I like the idea of cutting it all off at the source, rather than using ad blockers.

It seems like all the George Takei related websites bitch about ad blockers. Most let me click a link to close the pop up, but one doesn't have that link and there's no way to close it. I tried blocking that element with ublock but there's still something that prevents the page from scrolling until that thing closes.
