The discussion centers around the notion that Silicon Valley companies operate under an assumption of market efficiency, leading some to believe that any major inefficiency would be quickly addressed by competitors. However, the author counters this idea by highlighting two key points: first, that claims of systematic discrimination in hiring are misguided, and second, that there's a high demand for talent in tech companies, making them eager to find capable individuals. The author notes that while it's often argued that inefficiencies wouldn't exist if they were as apparent as

A recent study by cosmologists Dejan Stojkovic and his colleague suggests that if a primordial black hole (PBH) were to pass through your body, you likely would not suffer any fatal consequences. PBHs are theoretical, ancient black holes that may have formed shortly after the Big Bang, as opposed to the familiar black holes created from dying stars. This research proposes that evidence of PBHs could be found in hollow celestial bodies and potentially within objects on Earth. While scientists have speculated about

The author discusses their experience with Advent of Code, a programming event that they find to be a waste of time, as the puzzles are mostly irrelevant to practical programming. They aim to challenge themselves by participating in Advent of Code 2024 using Rust, a programming language they don't frequently use. Instead of opting for standard Rust development, they choose to implement it on an embedded system (the original Nintendo DS) that lacks a runtime and an established ecosystem.

The content discusses a proof of concept demonstrating that a WebAssembly (WASM) program can access files located outside the designated "preopens" directory in the Node.js WASI (WebAssembly System Interface) environment. Normally, accessing such files results in an error, but the concept explains that this restriction can be circumvented under specific circumstances, particularly through the use of a symlink that temporarily points to the outside file. Although this behavior indicates that Node.js WASI is not fully compliant with the WAS
