    • walrus01：I’m ordinarily loathe to post a link to reddit, but here is a very recent example of copper scrapping on an entire cargo ship that’s been abandoned by its crew (it took a hit from some kind of munition) in the hormuz area: https://www.reddit.com/r/SeaEmploy/comments/1vum7fj/the_f…
    • ChrisMarshallNY：One convenient fiction that many wealthy people (in the US) tell themselves, is that poor people are “lazy”; and that’s why they’re poor. I know lots of folks without a pot to piss in, or a window to throw it out, and not one single one, is “lazy.” In fact, a few have more than o…
    • intrasight：I live in Pittsburgh and I can tell you it’s still like that - which is convenient when you want to get rid of things. I had some scrap aluminum that I put out with the trash the night before pick up and it was gone before I had walked back to the house. A guy pulled up in a Suba…

Model XYZ is …

  • 核心评论:

    • walrus01：Much of this is why I stick to the rule of: a) Don’t quantize your KV cache b) Don’t run quantizations of the LLM that are worse than the best available Q8 (the largest possible file size unsloth GGUF for a given model like qwen 3.8 27B as an example). I would rather things go sl…
    • jonplackett：I just got qwen 3.8 27b mlx running on my Macbook Pro and honestly I’m pretty blown away by how not-dumb it is.
    • InvertedRhodium：I’m running Qwen3.8 aggressive uncensored Q4_K_P on a 4090 in a loop against the 2026 CrackMe CTF challenges. Using oh-my-pi in a prebuilt environment that I let Qwen build too. Codex wouldn’t even look at the files - literally, as soon as it read something with CTF it shut down….

I use this laptop in work and at home. I knew NetBSD was capable of much more, and I was hell bent …

  • 核心评论:

    • avhception：For me, it was Gentoo. I was a little bit lost after a bad time in the public school system, and not sure what to do with my life after that. I was fascinated by Linux, but never really got the hang of it. Used SuSE, which was fine, but I never really knew what I was doing. And t…
    • cavem0nkey：NetBSD was my favourite playing around OS from the late 1990s to about 2010. Worked on any old crap I had lying around which was mostly thoroughly obsolete SPARC and x86 kit. Did the job. Never went wrong. Good documentation built in. Netbooted on anything. No idea where it is no…
    • eahm：Awesome! Two things: 1) “We were” (sorry I had to do it). 2) Why NetBSD? Why not FreeBSD or Debian or heck even Ubuntu Server or RHEL/CentOS (forgot it was 2005)? Glad you got the spend more time with the family!

  • 核心评论:

    • asciimoo：Ohi, author here! Thanks for posting Hister. Feel free to A.M.A. My first free software search project was Searx, a privacy respecting metasearch engine, but because of the limitations of the metasearch concept, I’ve decided to take a different approach. Hister builds a personal …
    • quasigod：I just finished setting this up yesterday and I’m kind of obsessed with it. I was previously a heavy user of Karakeep, but I hated forgetting to save something and losing it. I also think Hister’s semantic search is a better solution than AI generated summaries and tags. Support …
    • wmchen：I set this up a few months ago based on asciimoo’s comments on HN, and barely used it at first, but I realized not too long ago that it could be a pretty useful research tool for one of my hobbies (award travel), that revolves around being in the know around various concepts and …

  • 深度解读: Hister 代表了一种反潮流的隐私工具思路：把浏览记录和本地文件变成个人可控的搜索索引。在主流搜索引擎和 AI 助手日益中心化的背景下，这种『自托管、无遥测』的方案切中了技术人员对数据主权的焦虑。

  • 摘要: A Friendly Introduction to Racket

  • 核心评论:

    • SA9G：My first language, 1980 in CMU, was Pascal… quickly followed by LISP in CS/AI courses and C for EE courses. I was a big fan of MacLisp at the time, the MIT version that GLS worked on (could see his comments all over the sources). Of course GLS moved on to Scheme and wrote a few…
    • GregBuchholz：> no special syntax for anything. (list ‘(1. . ##) -5/6+7.s-8i `(1 ,@2) 1@1 ;hmmm, no unquote splicing comma ;-) 10# ;surprised? (list #i+1 +1i 1+i) ;complicated or complex? #e-1e10i ;Old MacDonald? “(* 9 10)” #())
    • perrygeo：> In The Amazing Digital Circus (episode 8, “hjsakldfhl”), when Kinger opens the terminal to try to reset Caine, you can see that Caine (a creative AI built in 1996) is programmed in Lisp. The file is literally named Caine-core.lisp. Nice touch. Explains how Caine returns in epis…

  • 核心评论:

    • oefrha：I like how the $4.5T company can’t pay for the 100 engineering hours a year to maintain this, or just fork over the Claude tokens to do it, while they keep telling us how productive AI is making them (which, to be clear, has indeed made me a lot more productive).
    • nrabulinski：Given xip has been deprecated for a long time now, yet still is the format Xcode is distributed in, I highly doubt hidutil will ever disappear from macOS. Apple just won’t really update it anymore, just like they haven’t changed xip (not like hidutil has seen any significant chan…
    • binaryturtle：So I guess ram disks are deprecated too? (AFAIR hdiutil was the only way to create them)

  • 深度解读: 苹果在 macOS 27 中弃用 hdiutil，对依赖磁盘镜像工作流开发者和系统管理员影响不小。评论普遍关注替代方案、向后兼容性以及苹果近年来对底层工具链的频繁调整。

    • arikrahman：Let’s go, tangled.sh is about to have private repos
    • pocksuppet：So is this now just, like, a server?
    • ChrisArchitect：Spaces ? As someone reading this from the periphery (and not really even as I have been in the ecosystem, building etc), my first thought was this was some kind of live audio conversation thing ala Twitter Spaces. But nope. I know I know, you want to do your own thing, define you…
