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.

Hi there!

I’m Ricardson—a street photographer and open-source advocate with a lifelong passion for Linux (dating back to the Red Hat days!). Slackware 9.1 in 2004 was the distro that truly hooked me—its simplicity and "do-it-yourself" philosophy taught me the nuts and bolts of the system, and I’ve been a full-time Linux user ever since.

By day, I’m a Senior DevOps Engineer, scaling systems and automating chaos—after years of leading teams as a Manager and Head of Infrastructure. (Yes, I still miss the command line when stuck in meetings.)

These days, I split my time between:
📸 Capturing raw, candid moments through my lens—street photography is my way of storytelling.
💻 Tinkering with open-source tools—whether it’s tweaking my WM/DE, scripting, or testing FOSS alternatives.
🌐 Engaging with the Fediverse—I’m currently active on both BSD.cafe and Fosstodon, exploring the decentralized web.

I believe in privacy, minimalism, and the power of community-driven software. When I’m not behind a camera or a terminal, you might find me digging through vinyl records or sipping way too much coffee.

Let’s connect—I’m always up for a chat about photography, Linux, or obscure distros!

Talk of sex toy maintenance

Turns out cleaning & re-applying grease to a Hi-Smith Fucking Machine isn't particularly hard, only took me an hour on first go.

(I guess the grease on the piston had just seized up or become dirty)

But now I once again have a smoothly working machine ^_^

It's such a shame that programming has been (and in many places still is) limited to higher education under the guise of "complex maths required" and similarly elitist attitudes.

If you can read, write and have a basic understanding of how a computer works, you can learn how to code. That, is the minimum bar.

In a world increasingly dependent on technology, educational institutions need to teach responsible and efficient use from the start. Not just for the young either, everyone should be able to learn how to code, as it is fundamentally no more complex than writing a list of things the computer should do for you.

実に維新らしい。

“前代未聞な事が起きました!
「大阪・関西万博 公式ガイドブック」で未来都市のイラストを描きましたが、完成品ではなく、制作途中でレイアウト検討のために必要と言われスマホで撮って編集部に送ったものがそのまま載ってました!
こんな事30年描いてきて初めてです!”

I apologize for my error in handling a recent security vulnerability affecting private accounts

While I promptly resolved and deployed the fix, I failed to follow standard security protocols, underestimating the potential impact

It was a honest mistake, I never meant anyone harm

Remote followers-only content was temporarily exposed to new followers they didn't approve

We're implementing a new release strategy and appointing a CSO to prevent future incidents

I'm sorry, and will do better ❤️

In the first millennium CE, mathematicians performed the then-complex calculations needed to compute the date of Easter. Of course, with our modern digital calendars, this task is now performed automatically by computers; and the older calendrical algorithms are now mostly of historical interest only.

In the Age of Sail, mathematicians were tasked to perform the intricate spherical trigonometry calculations needed to create accurate navigational tables. Again, with modern technology such as GPS, such tasks have been fully automated, although spherical trigonometry classes are still offered at naval academies, and ships still carry printed navigational tables in case of emergency instrument failures.

During the Second World War, mathematicians, human computers, and early mechanical computers were enlisted to solve a variety of problems for military applications such as ballistics, cryptanalysis, and operations research. With the advent of scientific computing, the computational aspect of these tasks has been almost completely delegated to modern electronic computers, although human mathematicians and programmers are still required to direct these machines.

- There are no known vulnerabilities for Signal that don't come down to "if you intentionally show someone your messages, they can see them". - The social-engineering/"linked devices" attack DOD/Google warned about was real, but since February it's not been exploitable in practice. Update your apps

0

To summarize - The use of Signal in the "Houthi PC Small Group Chat" was legitimately bad, for security, opsec and legal reasons - Signal is agreed by security experts to be the best available messenger; you should install it; it can and should replace your regular IM/SMS app.

There are laws about this. One expects the executive branch should be using communication methods/servers that comply with these laws. Signal—where by design no one retains or has the ability to read messages except the recipient's own phones—surely doesn't. I believe this is *why* they used Signal.

When the executive branch makes decisions, records need to be preserved for - Auditors and law enforcement, later investigating if a crime was knowingly performed - The *next* executive branch, in four years, following up on the decision - Historians, when everything's declassified decades from now
