iwwr··on Spanish track was fractured before high-speed train disaster, report finds
Thanks for the clarification!
iwwr··on Spanish track was fractured before high-speed train disaster, report finds
AFAIK continuously welded tracks (like those used in high speed rail) are also slightly tensioned, so a break in a single point could make it look like a whole section of track is missing, as tension is released.
iwwr··on Kimi K2 1T model runs on 2 512GB M3 Ultras
What is it using for interconnect?
iwwr··on OpenAI's ChatGPT Agent casually clicks through "I am not a robot" verification
Each step in that chain is harder to do and more computationally expensive.
iwwr··on Show HN: Simple live calculator in Tree-sitter and cranelift JIT
So what does it do?
iwwr··on The 'Invisibility Cloak' – Slash-Proc Magic
Could you use a unionfs like overlay2 for more advanced pid hiding?
iwwr··on JSON Patch
What about auto-formatting the json and sorting all keys, to create some kind of canonical form? Then we can use standard textual patch.
iwwr··on Show HN: GitOps Template for Kubernetes
Genuinely interested. What problems did you have dealing with the standard reconciliation mechanism provided by ArgoCD and by k8s itself. I understand the advantage of the operator approach, but it might be hard to show the state in ArgoCD and somewhat breaks the idea of gitops.

Can we benefit your project in a more limited but agentless way? Limiting the types and CRDs we allow in k8s makes operations better, especially with the aggressive upgrade cycle that k8s already imposes.

iwwr··on Show HN: GitOps Template for Kubernetes
Why do you need an in-cluster operator/pod?
iwwr··on Who uses Accept-Language header?
This is a problem for me as a language learner on mobile. I set a keyboard with (for example) Russian, and suddenly the world looks Russian, even though I am far from comfortable in it yet. I wish there were a way for the browser to ignore some system languages. This is worse for apps because I also get served with localised versions, where I need to uninstall, remove system language and re-install.
iwwr··on Jd – JSON Diff and Patch
Is this useful for large json files, on the order of GiB?
iwwr··on A picture of the sun, taken with a neutrino detector, at night through the Earth
Deep down in the sun photons are absorbed almost as soon as they are created. In a sense the photons at the surface of the sun are the result of nuclear reactions thousands of years back. However neutrinos escape pretty fast and so can be used to gauge the status of nuclear reactions now.
iwwr··on It's not just CrowdStrike – the cyber sector is vulnerable
Or maybe switch to an operating system that isn't a security dumpster fire?
iwwr··on PeaZip: Open-source file compression and encryption software
In some restricted environments (e.g. containers in CI, build servers or AWS Lambda) you may have limited disk space or no write access at all, so it is useful to have a tool that can stream to memory while decompressing on the fly, and discarding what you don't need.
iwwr··on Google Assistant will lose 17 features in the coming weeks
> Who wants to send an email through the smart speaker?

People of limited mobility, without working limbs, holding babies, cooking etc.

iwwr··on Experts revive ancient techniques to make concrete more sustainable
The ancient Roman concrete was very different from modern: it was more thick, could not ne poured etc. But more importantly, it had no rebar, which is the main thing that corrodes over time. Ancient buildings could use molten lead to join together pieces of stone, but steel could not be made in the volume needed for reinforced structures.
iwwr··on Aerogel Core Fission Fragment Rocket Engine
Thanks!

So basically the fragments are escaping through the aerogel.

iwwr··on Aerogel Core Fission Fragment Rocket Engine
But why Aerogel? Is it easily compressible?
iwwr··on Solving the Expression Problem in Go
> The goal is to define a datatype by cases, where one can add new cases to the datatype and new functions over the datatype, without recompiling existing code, and while retaining static type safety (e.g., no casts).

Isn't this made moot by the prevalence of static linking or fat binaries in go-land?

iwwr··on OpenTF repository is now public
It's far easier for a project with many contributors. Plus, PRs and branches are cheap.
iwwr··on Unexpected downsides of UUID keys in PostgreSQL
Sequential serial numbers reveal information. See: https://en.m.wikipedia.org/wiki/German_tank_problem
iwwr··on Power on the moon: What will it take to survive the lunar night?
Nuclear appears to be the only realistic contender. But the mission architecture of Artemis goes around the problem by having only short stays on the lunar surface.

Even with nuclear, it can be far safer: small reactors need less containment. There is no risk of fallout without an atmosphere, and no ground water to contaminate.

Still, relying too much on it and failing (melting down) will put in danger the whole human space program. For low-power unmanned applications the RTG remains unbeatable.

iwwr··on Horizon Worlds Has Too Many Issues and the Team Building It Barely Use It
Could be that content creation tools are hard to do and the need for moderation. Second Life had a problem of easily accessible penises, while Minecraft servers have an issue with swasticas.
iwwr··on Tell HN: Sudden Chile daylight savings time rules change causes chaos
Some call it "chaos", others might call it "badly written software".
iwwr··on DRY is an over-rated programming principle?

iwwr··on Ask HN: How do you approach writing documents?
Maybe start scaffolding first. Split up the docs into standard sections: who this is for, what it intends to describe, level of detail (marketing, executive summary, runbook). Then fill in the sections at the level needed.
iwwr··on Utilities Want to Convert Coal Plants to Nuclear; Skeptics Abound
That one had some fundamental problems due to the choice of graphite moderator. Another selling point: the ability to refuel while the plant is running also did not pan out. In the end these reactors had somewhere around 50% capacity factor, compared to more mainstream designs that used water (light or heavy) at 90%. They are also being decommissioned early, again, due to graphite cracking over time. That said, it's not unfeasible to imagine these problems being ironed out in the end, but rollout coincided with the Thatcher Era, which deprioritized industrial developmend and fundamental R&D. It was not a good deal to buy one of these 1st gen UK reactors, compared to a GE/Westinghouse LWR/HWR.
iwwr··on Uranus should be NASA’s top planetary target – report
Besides just cost, the engineering constraints can be lower by making designs less complex and easier to do, also, faster. Free delta-v or smaller size constraints, as well as more predictible pricing. Or, 2 for the price of one, or, split up instruments on multiple spacecraft. Reusable spacecraft are a little like that :)

iwwr··on One machine can go pretty far if you build things properly
It's easy to have standardized setups, even immutable and rollbackable ones. What isn't so easy is troubleshooting when things go wrong, especially with many moving parts.

It's better to have a simpler, dumber system due to less things that can go wrong.

Do you have a particular thing for which you'd like "sysadmin in a box"?
