Accidentally Load Bearing
Sometimes people will talk about Chesterton's Fence, the idea that if you want to change something—removing an apparently useless fence—you should first determine why it was set up that way: The gate or fence did not grow there. It was not set up by somnambulists who built it in their sleep. It is highly…

Designing a SIMD Algorithm from Scratch
Another explainer on a fun, esoteric topic: optimizing code with SIMD (single instruction multiple data, also sometimes called vectorization ). Designing a good, fast, portable SIMD algorithm is not a simple matter and requires thinking a little bit like a circuit designer.

I almost bought a scanner
I almost bought a scanner. Mainly for my Alpine Panoramics project . The key here is that I am still shooting most of these photos on a Hasselblad Xpan - a long since discontinued film camera that shoots two 35mm frames side by side to achieve a panoramic frame covering approximately 65x24mm.

The other day I was visiting my family in Hawaii when I complained to my mother about not wanting to do a planned run that afternoon. I told her that I was tired and was dreading physical exercise. Despite that, I explained to her that I was going to do it, even if it meant I ran a lot slower than my regular pace.

LED lighting badly suppresses human melatonin production at night
Yes, it’s a spicy title. Yes, I plan to back it with what I consider very reasonable evidence of the claims, in the form of a lot of research papers. I would simply ask that you read to the end before deciding I’ve lost it.

SQL should be the default choice for data transformation logic
SQL should be the first option considered for new data engineering work. It’s robust, fast, future-proof and testable. With a bit of care, it’s clear and readable.

All you may need is HTML
Readers occasionally request which static HTML generator is used by fabiensanglard.net , and if they can take the same stylesheet/ fonts to start their own blog. I usually send back the whole 134 lines of gen.php [1] and invite them to copy whatever they need to get started [2] .

Functions are vectors
Conceptualizing functions as infinite-dimensional vectors lets us apply the tools of linear algebra to a vast landscape of new problems, from image and geometry processing to curve fitting and machine learning.

QGIS is the mapping software you didn't know you needed
QGIS is incredible: You can build maps that make use of the absolute wealth of public data out there and put Google Maps to absolute shame. This article is doing just that.

How I run my servers (2022)
I've been writing recently about servers and internet infrastructure 1 . A lot of this writing is predicated on running server software on a VM or physical machine, rather than using a more cloudy solution, which is somewhat unpopular these days. However, I think it's a pretty reasonable way to do things, and it's not…

Driver adventures for a 1999 webcam
We generally know that when we buy a piece of technology that it will not last forever, connectors wear out and/or go out of fashion. But I think the most frustrating reason to have to get rid of something is that drivers stop being made for devices.
