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.

Most hashtags are pretty obvious, you just put # in front of a topic. For example if a post is about coffee it might have the tag

However, many popular hashtags have difficult-to-guess names, so I've started a list to help people discover them:

➡️ fedi.tips/fun-and-useful-hasht

Copy-paste a hashtag into the search box in Mastodon if you want to browse or follow it.

If you have suggestions for non-obvious hashtags that should be added to the list, let me know in the replies 🙂

This week I began a 10-week course in identification and, following the maxim that faint heart never won fair lady, I have begun by trying to identify one of the most notoriously difficult lichens, a Cladonia.
This on a Scots pine and has all the characteristics of Cladonia polydactyla. I have some chemical tests and a scaled image to complete but these are a good start (and check out the tiny springtail which was barely visible to the naked eye).

Last week I hooked up with @jazjaz :twt: :wales_flag: from Tŵt Cymru, the community-owned Welsh social network. We’re combining forces to launch the first Tŵt app on March 1st, Dydd Gŵyl Dewi Sant (St David’s Day).

The Tŵt mobile app is vibrantly Welsh, easily accessible for new users, and a model for social communities worldwide. Reflecting the Pethau Bychain (Little Things) campaign behind the app. It’s all about building a digital commons from small acts of hospitality and kindness.

Everyone is looking for the fountain of youth–but dare we say, we probably found it.

It’s a fact, that laughter extends your life. Nothing rejuvenates the mind, body, and soul like a good chuckle. And we mean that whole-hearted laughter that comes from actual human-made art, not whatever algorithm-generated slop is currently clogging your feed like arterial plaque.

A scientist in a white lab coat stands on a ladder, pouring a small blue figure into a large yellow laboratory flask filled with bubbling blue liquid. The flask is heated by flames underneath and connected to tubes, suggesting an experimental setup for creating longevity.

RE: mastodon.thenewoil.org/@thenew

Next up will be a VPN ban. Many tech-y people will see that and think “lol yeah well that’s not going to stop *me* from using a VPN”

A VPN ban isn’t really meant stop you from using one. It means when they catch you doing so, they’ll use the fact you’re using this harmless technology itself as a *pretense* to lock you up without needing to do any “hard work” (i.e. an investigator’s job) like actually confirming whether you committed a real crime.

Don’t think you won’t be impacted just because you know how to outsmart an ISP filter! This is not a plan to protect children or stop you from consuming adult media. It is a ploy to eventually eliminate ALL freedom of expression and free access to information in the UK.

And the same goes for Chat Control and encrypted messengers, btw

I think some are still missing the point. I’m not saying they’re going to lock up every single person who uses a VPN or watches porn.

Your government’s strategy is to make “crimes” like this as common and easy to commit as possible.

This way, if you ever do something completely legal which they *actually* don’t like, *which can be completely unrelated to VPNs or bypassing age verification,* they can pull up your internet history and easily prosecute you.

Organize a legitimate protest, and the government’s swift response will be to label you a child sex offender because they found you using evil VPN technology.

This is how free speech dies, not from a law that says “free speech is dead now,” but from draconian, authoritarian laws like this that give the government “plausible” reasons to go after anyone, which can’t easily be fought against.

This has always been the playbook to target innocents. In the USA, drug possession laws being created as a pretense for cops to raid and dismantle minority communities, for example. And now this is coming to the digital realm.

We can grow something better! Punk Month 🖤

"We invest too much of our culture in centralized, for-profit, corporate social media platforms. These platforms enrich billionaires, expand surveillance, and fund the cult of capitalist war, all while trapping us with addictive algorithms that feed us mindless content. It feels necessary to be on these platforms to "stay connected", yet paradoxically they increase our isolation. Their purpose is to extract profit, not to help us connect.

Instead of jumping between online capitalist corporate platforms, we propose a radical alternative that's actually aligned with punk values: the Fediverse, a network for open, autonomous, decentralized, not-for-profit, and DIY social media.

The Fediverse is an interconnected network of social media platforms..."
