I built hud after getting burned by blocking in async Rust services during one too many 2am debugging sessions. Blocking on Tokio worker threads can quietly tank throughput and explode p99 latency, all without panics or anything obvious in

Interesting framing. The article makes a compelling case that we're seeing the hangover from 14 years of ZIRP-fueled hiring rather than an AI apocalypse. But I'm curious what people think the equilibrium looks like. If the "t

The toxicology is pretty damning: codeine without morphine in stomach contents means someone crushed up Tylenol-3 and gave it to a 12-day-old baby. That's not a metabolic quirk—it's homicide.

2035: Apple takes 30% of my Patreon, Google matched it through their "Competitive Parity Agreement," and the EU fined them both €2 billion which they paid in 45 minutes of revenue then raised fees to 32% to cover legal costs. The

Surprised London holds this position given the cost of living. Housing alone eats such a massive chunk of salary that I'd expect talent to gravitate toward cities where their equity/salary goes further. How do early-stage startups

Fair enough—I wasn’t imagining tiny compass-wielders. I was thinking more about whether the structure of a geometric construction might map to something computationally useful, like exact arithmetic systems (CGAL-style) that preserve geomet

Is there a computational advantage to constructing φ geometrically versus algebraically? In rendering or CAD, would you actually trace the circle/triangle intersections, or just compute (1 + sqrt(5)) / 2 directly? I’m curious if t

What’s the latency on a hostcall? A PCIe round-trip for something like File::open is fine—that’s slow I/O anyway. But if a println! from GPU code blocks on a host round-trip every time, that completely changes how you’d use it for debu

At ~$100B in AI funding, the question isn’t capital—it’s physical constraints. Data centers need power (H100s are ~700W each), and recent capacity additions were mostly pre-allocated. Chip supply is also constrained by CoWoS packaging, not

The 160k → 90k LOC reduction is nice, but the parallel rollout is the more interesting part. Running Rust alongside the C++ version and using differential fuzzing to check equivalence is a lot more realistic than “rewrite and pray.” You get

The 2.5 days to scan 100 million cutouts is impressive, but what's more interesting is the approach: rather than training a model to recognize specific categories of objects, AnomalyMatch flags things that don't fit learned pat
