Shallow Water Is Dangerous Too

news.ycombinator.com Kaufman 2026-01-17 09:22:22

Julia and I know drowning is the biggest risk to US kids 1-4, and we try to take this seriously. But yesterday our 4yo came very close to drowning in a fountain. (She's fine now.) This week we were on vacation with my extended family: nine kids, eight parents, and ten grandparents/uncles/aunts. For the last few years we've been in a series of rental houses, and this time on arrival we found a fountain in the backyard: I immediately checked the depth with a stick and found that it would be just

Tinyio: A tiny (~200 line) event loop for Python

tinyio A tiny (~200 lines) event loop for Python Ever used asyncio and wished you hadn't? tinyio is a dead-simple event loop for Python, born out of my frustration with trying to get robust error handling with asyncio . (I'm not the only one running into its sharp corners: link1, link2.) This is an alternative for the simple use-cases, where you just need an event loop, and want to crash the whole thing if anything goes wrong.

When Aret Oymakas started selling diamonds years ago, engagement ring shoppers came in looking for one thing for their brides-to-be: a real, mined diamond. "It was just a diamond," said Oymakas, owner of Livia Diamonds in Toronto. "And you got what you were able to get … in terms of design and budget." These days, not so much. Lab-grown diamonds have become massively popular in recent years, giving the traditional, mined version a run for its money. Oymakas says natural diamonds made up 100

Algorithm for simulating phosphor persistence of analog oscilloscopes

news.ycombinator.com Unknown 2026-01-17 20:56:30

Background to phosphor displays and analog oscilloscopes For all of you that have used analog oscilloscopes or other equipment with a phosphor display knows how beautiful the image can be from such displays. The color grading, which naturally occurs due to the persistence in the glow from the phosphor, also acts as a useful measurement on the signal integrity, such as how much noise there is and the shape/modulation of the underlying signal.

The Sail instruction-set semantics specification language

Implicit parameters are always integers, and they must appear first before any other parameters in the function type signature. The first argument can then just be omitted when calling the function, like so: Functions may also have implicit parameters, e.g. we can implement a zero extension function that implicitly picks up its result length from the calling context as follows: Sail will also ensure that the output of our function has precisely the length bits('n * 'm) for all possible inputs

‘Coyote vs. Acme’ Finally Comes Out Next Year, and We’ve Seen Footage

Two years ago, Coyote vs. Acme was a victim of Warner Bros. Discovery’s cost-cutting cancellation wave. Despite public outcry, it initially seemed like it’d never see the light of day. But things have worked out in its favor: it’s coming to theaters next year, and San Diego Comic-Con offered a first look at what’s to come in the Looney Tunes’ latest movie and, more importantly, a release date: August 28, 2026.

A few short weeks ago, directors Phil Lord and Chris Miller graced us with an extended first look at their upcoming sci-fi adaptation, Project Hail Mary. The three-minute trailer for a movie not coming out for nine months displayed supreme confidence in the project, and after watching it, you could see why.

s.p.l.i.t is the most badass typing game I’ve ever played. It’s actually more of a hacking simulator, cyberpunk thriller and puzzle experience than a typing game, but its core loop is bookended by sequences of high-intensity letter pecking with gruesome consequences — think Mavis Beacon as designed by Ted Kaczynski — and the final scenes have a way of searing themselves into your psyche. Not to mention, the whole thing takes place on a keyboard, no mouse or gamepad. So I guess it’s technically o

Ageing accelerates around age 50 ― some organs faster than others

Ageing of many tissues accelerates around age 50, according to an analysis of tissues in people ranging from teenagers to individuals in their sixties.Credit: Karen Haibara/AFP/Getty It is a warning that middle-aged people have long offered the young: ageing is not a smooth process. Now, an exhaustive analysis of how proteins change over time in different organs backs up that idea, finding that people experience an inflection point at around 50 years old, after which ageing seems to accelerate.

In sledgehammer every operation is encoded as a sequence of bytes packed into an array. Every operation takes 1 byte plus whatever data is required for it. Each operation is encoded in a batch of four as a u32. Getting a number from an array buffer has a high constant cost, but getting a u32 instead of a u8 is not more expensive. Sledgehammer bindgen reads the u32 and then splits it into the 4 individual bytes. It will shuffle and pack the bytes into as few buckets as possible and try to inline
