How to snapshot everything important with ZFS, and destroy the snapshots later - Sun, 03/30/2025 - 09:33

One of the coolest features of ZFS is that you can create snapshots of filesystems before making changes, and revert them later if those changes cause problems. This is great for major updates, especially involving experimental software. If you had your whole system on a single filesystem this would be very easy, but you probably don't, especially if you are using ZFS. Luckily, it is pretty simple to make and destroy these snapshots.

Build Linux (and ZFS) manually for Devuan - Sun, 03/30/2025 - 08:47

I run Devuan Linux, because I don't like systemd and I do like Debian. I have root on ZFS, which is a great way to protect your data but also comes with challenges. I wanted to install Linux 6.14 because I want NTSYNC support, but the latest release of OpenZFS for Linux does not support Kernel 6.14. However, the master branch of ZFS does support it, and has for a while now, so I decided to build ZFS myself so that I could upgrade my kernel.

Linux nvidia one-liner for maximum GPU power - Sun, 03/23/2025 - 07:01
nvidia-smi -pl `nvidia-smi --query-gpu=power.max_limit --format=csv,noheader,nounits`

This runs nvidia-smi to get the maximum power level for the GPU as a number alone, then runs it again and sets the power level to that number. This will work as long as you have only one nvidia GPU in your system. Otherwise take a look at the -i option information in nvidia-smi --help.

Softer Keyswitches for Devarajas - on Mechanical Keyboards and Swapping Switches - Sat, 03/22/2025 - 18:12

I got a Redragon Devarajas as an entry hotswap mech keyboard, with the red switches to try to keep things quiet. It's based on an eVision PCB, and the red switches I got it with (Which are Redragon branded) are a close match to Outemu Red. But they don't really make it that quiet despite being linear, because there's no damping in the switch. There is a foam mat under the PCB, but it doesn't do much at all. Long story short, I put in Outemu Silent Peach V1 switches and now it actually is quiet, and easier on the fingers.

Solar Panel Output Voltage - Sun, 03/09/2025 - 08:11
This is just a little something I dashed off in a Fb thread in a skoolie group, that I thought it might be nice to refer back to sometime.
MT7925 comes good with Linux Kernel 6.12 - Mon, 03/03/2025 - 19:24

My PC has an M2 WiFi slot so I figured– why not stuff something in it if I could get it cheap. And then I looked around, and found that I could get WiFi plus Bluetooth for next to nothing...

Vevor YT60234 weather station mini-review - Thu, 02/13/2025 - 17:23

I was recently shopping for digital rain gauges and finding any one I wanted to be over $30, and stumbled across a full weather station under $60 from a reasonably reputable brand. It has a good range of sensors, what I think is a generally good design, and it seems more durable than average (but it's early days.) This is a little micro-review of it.

OpenRGB, Linux, nollie - Sun, 02/09/2025 - 10:35

My PC has a liquid cooler in it with two ARGB fans, and an ARGB infinity mirror on top of the water block. I wouldn't have paid extra for the LEDs, but once I had them, I wanted them to do something. So I connected them to my ASRock motherboard, and played around with that functionality for a little while, but it turned out to have a serious deficit.

nvidia instrumentation lies, a lot - Sun, 02/09/2025 - 08:18

nVidia corp has emerged as the de facto standard for both 3d graphics and GPGPU (today, mostly "AI") for a variety of reasons including performance and ease of development. But they are irritating in multiple ways, and I've just discovered another one that probably everyone knew about but me.

The irritations of No Man's Sky - Mon, 02/03/2025 - 06:23

Because I have a lot of these, I didn't want to lump them in with my main blog on this game. But because there are a lot of them, I thought that it was worth posting my list.

Things that are still bad and/or stupid about No Man's Sky
Some of this could be fixed relatively easily, some not so much (technical or balancing issues)
I am removing things from this list if I discover they are false or outdated, help me out.
There be spoilers here.
