ZRAM and VMs

I’ve just started using zram for swap on VMs. The use of compression for swap in Linux apparently isn’t new, it’s been in the Linux kernel since version 3.2 (since 2012). But until recent years I hadn’t used it. When I started using Mobian (the Debian distribution for phones) zram was in the default setup, […]

Dell T320 H310 RAID and IT Mode

The Problem

Just over 2 years ago my Dell T320 server had a motherboard failure [1]. I recently bought another T320 that had been gutted (no drives, PSUs, or RAM) and put the bits from my one in it.

I installed Debian and the resulting installation wouldn’t boot, I tried installing with both UEFI and […]

Colmi P80 SmartWatch First Look

I just bought a Colmi P80 SmartWatch from Aliexpress for $26.11 based on this blog post reviewing it [1]. The main things I was after in this was a larger higher resolution screen because my vision has apparently deteriorated during the time I’ve been wearing a Pinetime [2] and I now can’t read messages on […]

Server CPU Sockets

I am always looking for ways of increasing the compute power I have at a reasonable price. I am very happy with my HP z840 dual CPU workstation [1] that I’m using as a server and my HP z640 single CPU workstation [2]. Both of them were available second hand at quite reasonable prices and […]

Links July 2025

Louis Rossman made an informative YouTube video about right to repair and the US military [1]. This is really important as it helps promote free software and open standards.

The ACM has an insightful article about hidden controls [2]. We need EU regulations about hidden controls in safety critical systems like cars.

This Daily WTF […]

Annoying Wrongness on TV

One thing that annoys me on TV shows and movies is getting the details wrong. Yes it’s fiction and yes some things can’t be done correctly and in some situations correctly portraying things goes against the plot. But otherwise I think they should try to make it accurate.

I was just watching The Americans (a […]

Bad Product Comparisons and EVs

When companies design products a major concern seems to be what the reviewers will have to say about it. For any product of significant value the users are unable to perform any reasonable test before buying, for a casual user some problems may only be apparent after weeks of use so professional reviews are important […]

Function Keys

For at least 12 years laptops have been defaulting to not having the traditional PC 101 key keyboard function key functionality and instead have had other functions like controlling the volume and have had a key labelled Fn to toggle the functions. It’s been a BIOS option to control whether traditional function keys or controls […]

The Fuss About “AI”

There are many negative articles about “AI” (which is not about actual Artificial Intelligence also known as “AGI”). Which I think are mostly overblown and often ridiculous.

Resource Usage

Complaints about resource usage are common, training Llama 3.1 could apparently produce as much pollution as “10,000 round trips by car between Los Angeles and New […]

Links June 2025

Jonathan McDowell wrote part 2 of his blog series about setting up a voice assistant on Debian, I look forward to reading further posts [1]. I’m working on some related things for Debian that will hopefully work with this.

I’m testing out OpenSnitch on Trixie inspired by this blog post, it’s an interesting package [2].
