Actually it did get used. Linux and Windows used the x86 TSS for process context-switching for years. During that time, Linux had a limit on the number of processes, which was due the maximum number of TSS entries that fit in the x86 GDT. E

CRIU is used by LXD to save the state of an LXD container, very similar to suspending or snapshotting a virtual machine. Unfortunately, I was disappointed to find `lxd stop --stateful` couldn't save any of my LXD containers. There w

It's not about the formula. The formula comes from the geometry. 1/r^2 falls out as the formula, starting from the geometry of "flux" and "field lines", along with "conservation of flux", in 3d space

Yes, this. Because of this, I saw substantial data corruption that had built up over years in live medical databases: The on-disk B+trees had corrupted internal links due to incorrect handling of concurrent updates and rollbacks. This made

I just ran phi3:mini[1] with Ollama on an Apple M3 Max laptop, on battery set to "Low power" (mentioned because that makes some things run more slowly). phi3:mini output roughly 15-25 words/second. The token rate is higher

Good point about all the people about to hit a mortgage renewal crisis. For our friends in the USA: in the USA it's common to have a long-term fixed-interest mortgage. In the UK they are limited to a few years, then you have to renew.

When you measure the flow of electrical power along a cable, the energy travels close to the speed of light, yet the electrons drift very, very slowly in comparison. Electrical power is transported as a fast-moving density wave in the elect

Reading about all these >= 1 Gbps connections, I'm envious. The fastest I've been able to get quoted to my office in the centre of a UK town is 17 Mbps, and to home it's 34 Mbps. The speed limits are both due to old infras

I think people's stated positions on CLAs are often not clearly thought out. Mostly when I've seen people object to CLAs, it's on the grounds that it's not acceptable for any company to be able to take freely contributed

`strncpy` is commonly misunderstood. It's name misleads people into thinking it's a safely-truncating version of `strcpy`. It's not. I've seen a lot of code where people changed from `strcpy` to `strncpy` because they

Rust doesn't solve this. You can easily make the same mistake as the article describes, in Rust. Thiez points out that a Rust mutex wraps the data it protects. But that doesn't fix the issue described in the article. The C++ in

A condition variable is used because the workers are waiting for a condition, `m_queue.size() > 0`, in addition to the kill flag. The kill flag is sticky, but the queue condition isn't.
