Also, the four fallacies of local computing: - The CPU is infinitely fast. - RAM is infinite. - CPU caches don't exist. - Cache lines don't exist.

It cannot be just a product of the body, else it could not have effect on the body and our tongues could not be moving speaking about it.

We don't experience the sun going up and down, we experience its direction changing relative to the horizontal plane, and it is not an illusion: it matches planetary motion. The mi…

Bounded collections still allow for useless reachings of their bounds, and corresponding memory and CPU wastes (and possibly functional/domain issues). The main reason I saw around…

Before, not after: when the code makes it hard to implement a new feature (the definition of technical debt: code that is properly designed but only for previous features), first r…

>Do people really argue about variable names? Of course they do. A program's code is mostly a graph of names; they can be cornerstones of its clarity, or sources of confusion and b…

>where each line is extracted into its own method As John Carmack said: "if a lot of operations are supposed to happen in a sequential fashion, their code should follow sequentiall…

I can guarantee you that I have been doing just that for 20 years, creating and working on the same codebase, and that it only got better with time (cleaner code and more robust ex…

When I do functional unit tests, they tend to include the same functional logic as the code to test. What I strive for is then to express it in a different and possibly clearer way…

Agreed. A program is made of names, these names are of the utmost importance. For understanding, and also for searchability. I do a lot of code reviews, and one of the main things …

I only use "TODO" eventually followed by a sub-classification like "TODO bug": it maximizes discoverability by other devs and tools, and allows for a lot of variants (both technica…

Or: the hardware that generates beliefs about how things should be - whether based on religious or ideological dogma -, as opposed to science which is not prescriptive and can only…

Domains are often not very deep, as a lot of people need to understand them. I've seen smart people quickly figure things out and propose upgrades in a matter of weeks, on points l…
