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.

Exactly one year ago, on 30th December 2024, I laid the foundation of FediMeteo.

I took a VM, installed FreeBSD, and set up the first jail to support Italy. The goal was to create a tool for my own use, support a few countries, and announce it.

Unexpectedly, the enthusiasm was incredible. That pushed me to keep going, support more countries and cities, and turn it into what it is today.

FediMeteo now supports 38 countries and 2,937 cities, with more than 7,700 followers in the Fediverse alone, not counting the many people who follow via RSS feeds or visit the web pages.

If you are curious to read the story and some technical details, you can find it here:

Today is also Tuesday, a , so I want to say thanks to:

* OpenMeteo - @openmeteoOpen-Meteo 🌤🌍 - for providing accurate, high quality data, without which FediMeteo would be far less useful

* @grunfinkThe Real Grunfink - creator of snac, who made all of this possible using very few resources, on a 4 euro per month VM

* FreeBSD, which thanks to the efficiency of the OS and its jail implementation made it possible to run this service in a stable and efficient way with minimal effort

* FediFollows - @FediFollows - that periodically spreads the word about cities, countries, and the enthusiasm around the project

*All of you*, who suggested, encouraged, corrected, and celebrated this project

And forward toward supporting more countries and other interesting features already in the works.

Happy birthday, FediMeteo! 🎉

If I go to a magic show, I give my consent to be tricked. Again in ways that are nuanced and revocable, but there is consent given in some limited form.

That feels especially true in the modern world, where everyone is trying to trick me in any number of ways. Advertising is, almost by definition, a kind of nonconsentual magic.

I did not give permission to whomever is painting hamburgers out of edible wax to try and trick me by making me think that hamburger is what I will get when I fork over $15 at a drive through. I did not give permission to anyone trying to language-hack my brain Snow Crash style until I buy their product, sign up for their service, give them my money.

So out of the blue I got a request for access to a 10 year old Google Docs file. This request also came from someone who actually might be interested in that file, so I contacted him. Turns out he was making **exercise schedules** and had asked Google Gemini for help, and Gemini decided it needed access to my document on a new government law (from 2015). So be careful out there!

If you play D&D or read a book or watch a movie or play a video game, you're giving consent to have your feelings manipulated. That consent is revocable — you can stop playing, put the book down, turn the movie off. There's real and serious issues with how that consent is negotiated and communicated, whether your consent is informed, and the like. I don't want to gloss over those, only note that there is some form of revocable and conditional consent offered.

PSA I guess: "No means no" applies to much more than just sex. If you ask if someone wants to do something, and they say no, then don't be pushy and say things like "oh come on, it's fun!" or repeatedly push them to do the thing. Maybe they know themselves better than you do?? If you're disappointed that they don't want to do the thing, then that's a you problem. All consent should be informed and enthusiastic regardless of the context.

exo-openでatrilにPDFを開いてもらうと同じPDFはひとつのウインドウでしか開けないみたいなので遠くのページを同時に参照するためにFirefoxでも同じPDFを開いています。ウインドウ内で分けて閲覧できるのはAcrobatだったっけ…

The H-Watch is an opensource, long-lasting health monitoring wearable. Utilizing integrated NB-IoT technology, it offers direct, secure cloud connectivity. Although built with off the shelf components, its design focuses on low power consumption and on board intelligence. With an average power draw of just 5.9 mW, it achieves a 9-day battery life, which extends up to 20 days with its built-in solar harvester. The whole project is opensource.

I picked up a spare RPi4 from home over lunch, installed X on it (the hard way), and now I have a semi-working kiosk running on it.

Between this raspberrypi.com/tutorials/how- and some LLM guidance, I have a working proof-of-concept running on a TV in my office.
