excerpt from https://antonz.org/go-1-24/
"Computational processes are abstract beings that inhabit computers. ... [W]e conjure the spirits of the computer with our spells. A computational process is indeed much like a sorcerer's idea of a spirit. It cannot be seen or touched. It is not composed of matter at all. However, it is very real." Harold Abelson, "Structure and Interpretation of Computer Programs", 1984

blog post excerpt that reads “We’re building a platform, not a product”. If you hear this, run away. Platforms come from products, not the other way around. People don’t buy platforms. They buy one product at a time that somehow differentiates itself from every other product in their life. And then they move onto the next one. And the next one. You need to make standalone, great products, and if they can eventually all talk to each other 10 or 20 years down the line, then great. (Tony Fadell, founder of Nest, lead engineer who oversaw invention of the iPod) A product solves a specific problem for a specific user. Platforms have to start here too. Otherwise, they’re DOA.

text from a blog post that begins "The program is asking the C implementation to answer a simple question: if we add one to the largest representable integer, is the result negative? This is perfectly legal behavior for a C implementation" and shows four terminal outputs, 1, 0, 42, and "Formatting root partition, chomp chomp"
excerpt from an article on distributed systems: When we try understand how a system works, or why it’s not working, the first task is to establish causality. Thing A caused thing B. Here in our weird little universe, we need thing A to have happened before thing B for A to have caused B. Time is useful for this. Prosecutor: Why, Mr Load Balancer, did you stop sending traffic to Mrs Server? Mr LB: Simply, sir, because she stopped processing my traffic! Mrs Server, from the gallery: Liar! Liar! I only stopped processing because you stopped sending! If we can’t trust the order of our logs (or other events), finding causality is difficult. If our logs are accurately timestamped the task becomes much easier. If we can expect our logs to be timestamped so accurately that a A having a lower timestamp than B implies that A happened before B, then our ordering task becomes trivial.
