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.

The fediverse now has a mobile-first personal server called Holos by @HolosSocial (via @appsFedilab Apps). It's a full ActivityPub server that runs on your Android device (iOS coming soon). You own your identity with a custom domain and your followers live on your device.

Project URL: holos.social

Key features:
✅ Your server on your phone – Your identity, keys, and followers live on your device, not a giant shared server.
✅ Custom domain identity – Permanently own your handle (@you@yourname.com) and take it anywhere.
✅ True E2EE for DMs – Real end-to-end encryption for private conversations, a major privacy upgrade.
✅ Relay-based connectivity – Connects to the wider fediverse via relays, so a personal server is practical on mobile.

Open source, privacy-focused, and built to give you real ownership in the fediverse. The Android version is available now.

Here's Our First Gemini Deep Think LLM-Assisted Hardware Design

We've been using LLMs for software and firmware for years... now we're trying hardware. Threw a MAX44009 datasheet at Gemini Deep Think, asked for an EagleCAD library file, and about 10 minutes later it popped out working XML. Loaded it in Eagle, checked the pins and dimensions, rolled with it.

Composite image showing AI-generated EagleCAD library for the MAX44009 lux sensor: upper left shows the schematic symbol editor with VCC, SDA, A0, SCL, EP, GND, and INT pins correctly assigned with power, input, and I/O directions; upper right shows the UTDFN-OPTO-6 footprint with exposed pad and pin 1 indicator dot; lower left shows the finished Adafruit STEMMA QT breakout board render with the MAX44009 mounted, surrounded by pink neon glow; lower right shows a retro bowling alley "FIRST TRY" celebration graphic with chrome 3D text and starburst effects... because the AI-generated footprint actually worked on the first attempt.

@adafruit but… why? You talk about how this piece was made but don’t actually describe what it does. Why would I want yo buy this hardware? The only advantage you’re giving me is it was designed by AI.

AI sucks, you should feel bad for using such environmentally regressive tech, and you should feel embarrassed that your embrace of this imprecise, unproven technology shows your institution has poor critical thinking.

@orangutanlibrarianSam @adafruit because genAI companies are anti-social parasites who only thrive by stealing everyone's creations without asking for permission or giving even a thought to compensation. From music to art, from books to shitposts. Everything stolen and the result sold for money.
They destroy lives of people from artists to engineers.
They eat energy and capital at an insane rate, and the crash will be a desaster.
Use genAI and accept all of the above as inevitable, or fight it.

(지금 당장은 어렵겠지만 결국은 미국 혹은 어떤 나라가 됬던간에) 정부레벨에서 부의 엄격한 상하한선을 도입하고 0.1% 미만의 정신나간 부자를 탈탈 털어서 정부의 재정을 정상화하는 것이 어찌보면 재정적으로 건전한 정부와 사회를 만들 유일한 해결책이긴한듯... 다만 다시 이렇게 되려면 수십년이 걸리거나 혹은 정신나간 이벤트가 일어나야 가능할듯 ㅠㅠ

How do we clearly communicate to less tech focused people the issues with something like Ring cameras? My mom needs some security cameras so I immediately said “ok we’ll find something but don’t use ring cameras” and she asked if I didn’t think a ring camera could cover the areas she needed. I explained the ICE affiliation and she got it but I wish she had already known. She is still in the twin cities so “no ICE” *is* front of mind.

This Saturday I'm running a YouTube live stream specifically on how to build iOS apps with AI. We'll look at Xcode 26.3, plus Claude Code, Codex, Gemini, agents files and skills, and more. It's going to be packed! Set a reminder here: youtube.com/live/sc6pvW6vQzA

“More than 16 million tons of mill waste removed from project near the Colorado River"

While this is good and a rare example of corporate responsibility in the industry, this doesn't mean the 16M tons of waste are “safe” now, they are just someplace else.

Sure, AI is costing $billions and consuming copious resources, all to produce creepy slop that barely anyone likes. But the alternative would giving that funding to actual human artists. Can you imagine!?! Countless talented people, with free reign to create. What sort of world would that be!?

We're looking into implementing interaction controls in , following the approach proposed by . This would let you decide who can reply, like, or boost your posts. It fits well with the Holos philosophy of giving you full control over your online presence. More details here: docs.gotosocial.org/en/latest/
