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 […]

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].

PFAs

For some time I’ve been noticing news reports about PFAs [1]. I hadn’t thought much about that issue, I grew up when leaded petrol was standard, when almost all thermometers had mercury, when all small batteries had mercury, and I had generally considered that I had already had so many nasty chemicals in my body […]

The Intel Arc B580 and PCIe Slot Size

A few months ago I bought a Intel Arc B580 for the main purpose of getting 8K video going [1]. I had briefly got it working in a test PC but then I wanted to deploy it on my HP z840 that I use as a build server and for playing with ML stuff [2]. […]

Matching Intel CPUs

To run a SMP system with multiple CPUs you need to have CPUs that are “identical”, the question is what does “identical” mean. In this case I’m interested in Intel CPUs because SMP motherboards and server systems for Intel CPUs are readily available and affordable. There are people selling matched pairs of CPUs on ebay […]
