Hardware

Background Several months ago one of the Computer Recycling Project at The Working Centre’s donors donated some 2U HP server hardware. One of those machines was a nice HP ProLiant DL380p Gen8 server. The server came complete with 128GB of RAM, and it had 6 x 146GB SAS (Serial Attached SCSI) drives. While it’s always nice to get any storage and RAM with donations, I needed a bit more storage for what I had in mind. Luckily we had an HP storage array at the back with a bunch of 300GB SAS drives I could just pull out of the array, and plug into the ProLiant DL380p Gen 8, or so I thought… ...

Part of Computer Recycling’s build workflow process can be found in the LibreOffice Writer Laptop Build Checklist on GitHub. This isn’t the entire process, but serves as a guide for new volunteers on things that we check, test, and do, to prepare a laptop with Linux Mint (currently 22.3). We also have some quality assurance steps that are not documented in that checklist, as we prefer to have several eyes on 1 build, in order to ensure we don’t miss things. ...

Solaar is software for more than just pairing wireless keyboards and mice Back on April 8th, 2025 I wrote about Using Logitech unifying devices with Linux in which I discussed how to use Solaar under Linux Mint, or Xubuntu, to pair Logitech unifying wireless devices. My goal with that article was just to provide simple instructions for people looking to pair their Logitech wireless unifying devices, but it turns our Solaar has other functions depending on the device. ...

I tried AI on my Lenovo ThinkPad T430s under Xubuntu Linux and it did something shocking! Yes, the heading above makes this seem like zoo of bad artificial intelligence videos on Youtube, but I was actually shocked at what happened when I tried to install Ollama on my ThinkPad T430s running Xubuntu Linux 24.04.2. Entertain me for a second and let me briefly explain why I was surprised: I’ve installed Ollama a bunch of times on hardware several years newer than my laptop. Ollama will run if you don’t have a modern graphics card (which sounds a bit strange since it’s mostly text based, but having a decent, modern Nvidia graphics card can really boost Ollama’s performance). ...

Logitech unifying, but needs configuration Logitech’s unifying system is nice for a few reasons: Any device with the Logitech unifying symbol should work with a unifying dongle. Up to 6 devices can attach to one unifying dongle. There are plenty of Logitech devices that are part of the unifying ecosystem. If you buy a new Logitech wireless keyboard direct from a retailer, chances are you can just plug the dongle into your computer, turn on your wireless keyboard, and work. But if you buy Logitech devices used, and/or they don’t come with the unifying dongle, a little work might be needed to get the device paired with the dongle. ...

Don’t physically remove a USB key without unmounting or ejecting it first I have destroyed my fair share of USB keys in the past by prematurely removing the key before it was safe to do so. I remember being particularly irked when my $70CDN 1GB Kingston flash drive stopped working. I think at the time I swore I’d never buy Kingston crap again, but I’m not so sure it was ever Kingston’s fault (to be fair, USB keys were fairly new on the market back then). Like a lot of people, I assumed you could just save a document, or copy your files over, and then pull the USB drive out. Maybe this was just a bad habit I picked up from my days of removing floppy disks (they never got corrupted either)? ...

Hardware and Linux Distribution Differences This post covers a bunch of areas of media decoding and encoding that I’ve discovered over a number of years using Debian-based distributions like Xubuntu, and Linux Mint. Primarily I’ll cover some of the differences between Xubuntu and Linux Mint, how various hardware (CPUs and graphics cards) encode video, and some of the “gotchas” when it comes to different methods as they apply to Handbrake (software) and MakeMKV. ...

Initial look at artificial intelligence We might be a bit late to the game, but I’ve started looking at what we need at the Computer Recycling Project to run artificial intelligence models locally (on the machine, versus on the server) under Linux. The Ollama project makes it very easy to install a number of artificial intelligence models under Linux. Once ollama is installed you can download a model by typing: ollama pull <model name> So if you wanted to pull Llama 3.2 you would type: ...

Suspend doesn’t work on some Linux distributions – Lenovo Yoga S1 Our experience with Linux Mint XFCE has been pretty good so far at The Working Centre’s Computer Recycling Project, but we recently ran into an issue where a couple of Lenovo Yoga S1 laptops refused to suspend when the suspend button was clicked. Now before someone goes on about Linux, I want to point out a couple of things: ...

It lives, it dies! Our new TrueNAS server is up, and all the hardware is working, but not without some hiccups on the way. After taking a lot longer to build than expect, I was so happy the other evening when I posted about the successful Power On Self Test (POST), and the new RAM (32GB) being properly detected. Exhausted at the end of the day I left the drives disconnected and the video card out. ...
