So, back in 1997 I installed my first copy of FreeBSD. I had to do some major research to get X Windows up and running, and the next computer I bought I very carefully selected a video card to make things easier. I was happy, I was able to use gcc, but getting online via
Compatibility of FreeBSD on a Lenovo Thinkpad T480, notes and fixes (HiDPI, Trackpad, camera, etc).
This is Part 6 over 6 of "Coding for SSDs". For other parts and sections, you can refer to the Table to Contents. This is a series of articles that I wrote to share what I learned while documenting myself on SSDs, and on how to make code perform well on SSDs. In this part,

Absolute memory bandwidth figures tend to look fairly large, especially for GPUs. This is deceptive. It’s much more useful to relate memory bandwidth to say the number of clock cycles or inst…
Just say no to LM741 and LM324 / LM358.
The new TPU v5p is a core element of AI Hypercomputer, which is tuned, managed, and orchestrated specifically for gen AI training and serving.
Counterfeits CPU were very common in the mid-90s. The worst period was between 1993 (just after the launch of the Intel 486 DX2) and 1998 (when the Pentium II started to be multiplier-locked). It was extremely easy for tricksters to remove the original marking and reprint another one with a higher f

An interactive exploration of how GPS works: from the speed of light and trilateration to the cheap clock problem and Einstein's relativity corrections.
It’s been over a year since I created the first version of my Ambilight clone , but I finally found the time to return to it and add some new features. I was originally planning on adding colour correction (to correct for the purple wall behind my TV) and output delay (to get perfect synchronisation with the TV), but…

Earlier this week, as part of my work doing a more complete review of the Raspberry Pi 4 (coming soon!), I decided I'd go all-in and spend one entire day working entirely (or at least as much as possible) from a Raspberry Pi. And not just doing some remote coding sessions or writing a blog post—that's easy to do on a…
