Show HN: Calclock, Countdown/Lifeclock, Configurablehttps://thysys.com/happy-new-year.htmlI originally built this in Visual BASIC in 1994 for a friend who was in McMurdo Base Antarctica waiting on an 'Air Drop!' that was still months away, that would bring fresh food and much-desired mail to its denizens. It was a looming event everyone was anticipating and the waiting was cruel. No shortages but the 'freshies' run out first and for long spans everyone had to eat from cans, which saps morale. People would barter for spare batteries. I said via email "Sorry I cannot help you... but HERE is something that will make the wait even harder to bear! Hopefully it will become funny after awhile." So I sent him a CALCLOCK counting down to Air Drop. For awhile I used it to countdown to various things and to make life clocks.It stopped working a long ago. It was made using 16-bit Visual BASIC so ancient it even crashes the wine emulator today.This is the 2025 rewrite.

Choosing the Right Stainless Steel Utility Sink for Heavy-Duty Usehttps://news.ycombinator.com/item?id=46297672In industrial and commercial environments, every piece of equipment plays a role in keeping operations efficient, safe, and hygienic. Among these essentials, the utility sink often works quietly in the background, yet it supports countless daily tasks. From manufacturing plants to commercial kitchens and maintenance workshops, choosing the right stainless steel utility sink for heavy-duty use can make a measurable difference in workflow and durability.Heavy-duty environments place higher demands on sinks than residential spaces. They are used for washing tools, handling raw materials, cleaning components, and managing waste liquids. A well-designed sink must withstand frequent impact, exposure to chemicals, and constant moisture without compromising performance or hygiene. This is where stainless steel stands out as a preferred material across the metal fabrication and industrial equipment sectors.One of the first factors to consider is material grade and thickness.

Ask HN: Better places to work for burntout SWE?https://news.ycombinator.com/item?id=46211822I've tried my share of startups and megacorps, FAANGs. I am in a stage where I cringe on hearing a mission is so important that it needs a 996 culture. I also hate work getting stolen in the name of collaboration and politics in general thats daily business in Megacorps. I just want to bang out code, mentor juniors and deliver value in a small team that doesn't have an unhealthy obsession with growth or overworking. Maybe with rich founders who don't want to get more rich.Where can I find good places to work, especially in the US that offer: 1. Remote first setting 2. Mission oriented like Privacy, non-profit background etc (or Open Source with proven history) 3. Holocracy/Flat structureI think the above 3 criteria will really narrow down places that prioritize mission over growth/profits and automatically not pay a lot yet have a higher technical bar that deters a lot of folks who would end up optimizing for things that lead to a mess. Am I looking for a Unicorn?Dec 9, 2025 10:50 PM

Show HN: Detail, a Bug Finderhttps://detail.dev/Hi HN, tl;dr we built a bug finder that's working really well, especially for app backends. Try it out and send us your thoughts!Long story below.--------------------------We originally set out to work on technical debt. We had all seen codebases with a lot of debt, so we had personal grudges about the problem, and AI seemed to be making it a lot worse.Tech debt also seemed like a great problem for AI because: 1) a small portion of the work is thinky and strategic, and then the bulk of the execution is pretty mechanical, and 2) when you're solving technical debt, you're usually trying to preserve existing behavior, just change the implementation. That means you can treat it as a closed-loop problem if you figure out good ways to detect unintended behavior changes due to a code change. And we know how to do that – that's what tests are for!So we started with writing tests. Tests create the guardrails that make future code changes safer. Our thinking was: if we can test well enough, we cDec 9, 2025 5:35 PM
