What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

Being on Team Words Mean Things is difficult these days, particularly when multibillion-dollar companies put out breathless press releases saying "By using our massive language model, whose training data includes every version of GCC ever released, and having it autocorrect its own output by testing it against GCC, we managed to make a C compiler that mostly works for only $20,000 in a week and gosh I have so many feelings."

I mean, what the fuck are we even doing here.

The fix was to use GCC as an online known-good compiler oracle to compare against. I wrote a new test harness that randomly compiled most of the kernel using GCC, and only the remaining files with Claude's C Compiler. If the kernel worked, then the problem wasn’t in Claude’s subset of the files. If it broke, then it could further refine by re-compiling some of these files with GCC. This let each agent work in parallel, fixing different bugs in different files, until Claude's compiler could eventually compile all files. (After this worked, it was still necessary to apply delta debugging techniques to find pairs of files that failed together but worked independently.)

Will Mastodon, the platform that keeps the alive, miss a strategic opportunity to bring official institutions on board at scale?

By watching how is being marketed compared to , it certainly seems that way.

I wish the folks at Mastodon would invest in more professional marketing, similar to what we're seeing from its rival, Bluesky.

There was a major meeting in the EU Parliament focused on this topic, yet there was no announcement or microblog post from Mastodon. Zero engagement.

Compare these two approaches:

As much as I bash on the stupid ways that companies are trying to shove AI down everyone's throats, it does seem to be remarkably good at finding vulnerabilities. I'm a little concerned that our over-reliance on racing to patch everything 24/7 isn't going to scale well for much longer (if indeed it ever has).

As this blog post from Anthropic points out, this is becoming a frequent refrain from people advocating that companies invest more in AI.

I'm not necessarily saying they're wrong in this respect. But I am generally wary of any industry that claims you need more of what it is selling just so you can offset the negative externalities caused by the unbridled use of its technology.

"Claude Opus 4.6, released today, continues a trajectory of meaningful improvements in AI models’ cybersecurity capabilities. Last fall, we wrote that we believed we were at an inflection point for AI's impact on cybersecurity—that progress could become quite fast, and now was the moment to accelerate defensive use of AI. The evidence since then has only reinforced that view. AI models can now find high-severity vulnerabilities at scale. Our view is this is a moment to move quickly—to empower defenders and secure as much code as possible while the window exists."

cleaning up some personal projects I worked on in the past months and won't have much time for when my new job starts (Monday):

**cosmo** - a fast command line tool for converting data into GeoJSON(seq) or parquet.

Another one of those you say? Sure, but this one takes the best of some of the existing tools and combines them into one:
1. speed
2. scale (entire planet with ease on a 16GB laptop)
3. really good data filtering and transformation using YAML.

On the one hand I'm very tired. The state of the world around us is truly terrible and nobody can ignore it. But on the other hand I'm not giving up. The struggle will be long but we must never give up hope. We'll make this world a better place, this society a better society and ultimately ourselves better human beings.

今天是侄女出世D44,有一個重大進展,就是找到她合用的奶瓶了!之前的奶瓶不是出奶量太大導致她一直嗆到,就是出奶量太小,她用力吸了半天只吃到一點點奶,最後又餓又氣地大哭;今天才發現之前陰錯陽差地一直用錯奶瓶,那個正確的奶瓶一直在家裡但沒拿來用。

最近和弟妹聊天,一如往常地聊著「如果她長大怎樣怎樣」,但這次的話題更遠很多,是「如果她以後生小孩了,你們願意幫她帶嗎」?沒想到弟妹說她有考慮過!她覺得也許女兒也會像她一樣,40歲才生小孩,那時她都80歲了,「我一想到有那天,就開始都爬樓梯(取代坐電梯)回家了」。我大受震撼,第一次感受到當媽媽會下的決心是多麼巨大。為了40年後還是能幫上女兒,從現在開始她要健康直到度完人生。

以前也說過,侄女非常纏人,基本上整天都是在爸爸或媽媽身上度過,不願意躺在床上。問了到府查看的助產士,回答是一年內不建議放著她一直哭,也就是台灣通常會做的睡眠訓練(基本上就是狠下心讓嬰兒哭累睡著),在德國根本不建議做。超驚人的……

但我們的確也狠不下心這麼做,在能做的範圍內,我們都想盡量滿足寶寶的需求。不知道能做到什麼時候……

It’s extra important for our Members of Congress to hear from us right now. With a DHS funding deadline looming next week, we must demand that Democrats hold the line and refuse to fund DHS without ironclad limits on ICE and CBP, actual accountability for abuses, and clear guardrails to stop raids and intimidation: act.indivisible.org/sign/ice-o

THOUGHT FOR THE DAY:

The singularity has been cancelled.

What we're getting is wall to wall spam generators, optimized for passing the (modified) Turing test and convincing gullible humans that they are "intelligent".

Instead of the singularity, we are getting the spamularity.

Re-discovering that "Hesitation Marks" is the one and only Nine Inch Nails album that Tidal doesn't have¹ and cracking up all over over again

"Oh, you didn't want *that* one"

感觉 国人是被电子垄断养大的 已经习惯于饭被喂嘴里了 比如:

截至2025年第一季度,微信支付市场份额已达到59.7%,支付宝则降至36.2%。
从抖音延伸出的豆包用户占比53.13% 而ds只有29.96%
或许大家已经习惯了一路延伸被推荐应用 手机里存在一个独立的app是一个非常陌生的事情 去检索而不是被推送到它的存在 去应用商店或者官网下载它 更是一个难以执行并且高门槛的任务(或许)

Huge thanks to everyone who dropped in to the chat for our Pilot Episode of Sound Table on .

If you missed it it’s now available on demand on @peertube via @spectraSpectra Video: spectra.video/w/4AgQugdHWn6Q1R

It’ll also be popping up again on TIBtv during some of the NHAM Talk hours (nham.co.uk/tv/), as well as on NHAM radio on ‘Talk Tuesdays’! (nham.co.uk/listen/)

Feedback on the pilot episode gratefully received for improved future shows. 👍

Having been through the US immigration process (I got my first work visa more than 25 years ago and became a citizen in 2022), it's obvious to me that Americans have *no idea* how weird and tortuous their immigration system is:

A suburban house; on the law stand a couple, their backs to it, looking appreciatively upon it. On the lawn is a lawn-flag reading 'Chinga la migra' in ornate script, surrounded by butterflies and flowers. The flag is limned in red spokes.

The Tokaido Shinkansen continues operating in conditions that would shut down most rail systems.

**Engineering behind it:**
🔹 Advanced snow detection sensors
🔹 Heated track switching systems
🔹 Aerodynamic design prevents snow buildup
🔹 Real-time monitoring & predictive maintenance
🔹 Automated de-icing systems

Since 1964, the Shinkansen has maintained a perfect safety record while running at 320 km/h.

RE: glammr.us/@spagotto/1160240758

As another commenter pointed out, this is likely a change made in response to scraping of metadata (see: OCLC lawsuit against Anna's Archive, etc). However I suspect it would be trivial for a scraper to create a WorldCat account and then proceed with harvesting metadata from the site. Maybe this change is just to establish the context that the metadata is not a free resource for anyone to access online?
