Hachyderm is the El Paso of the Fediverse

It can be kind of hard to understand how big a server (instance) on the Fediverse really is. I know mastodon.social is much bigger than the server I'm on, but how much bigger, really?

So what if we compare the populations of servers to cities?

I built a tool for that! arewedecentralizedyet.online/f

Let's compare mastodon.social, the biggest server on the Fediverse, to the biggest city in the world, Shanghai (pop 24.9M). In comparison, pixelfed.social is like Ahmedabad, India (pop 6.4M). hachyderm.io is like El Paso, Texas (pop 679K). The server I'm on, discuss.systems, is like Eisenhüttenstadt, Germany (pop 32.1K).

Cool but maybe I'm not so familiar with some of those cities. What if we compare to cities in Mexico? (mastodon.social is Mexico City, Hachyderm is Tepic) Or Ontario? (mastodon.social is Toronto, Hachyderm is Caledon).

Play around with this tool, select an area of the world you're familiar with, and get a better sense for how big all these servers really are! Check out what your own server is comparable to!

Learning that white people in Minneapolis are putting Mexican flags on their cars, to make ICE waste their time pulling them over (instead of migrants.)

This is a very cool thing, and precisely the kind of "total oppositional" thinking people need to be doing right now to meaningfully disrupt the fascist project in whatever ways they can. Obviously you're not toppling Hitler by putting a flag on your car, but we need to be thinking about ways to make doing fascism COST more, everywhere.

"リチウムは地殻中での存在量が限られており、需要の急増に伴う価格変動(ボラティリティ)が激しい。2025年半ばにはリチウム価格が底値を打った後、短期間で50%以上も急騰するなど、自動車メーカーにとってコスト管理上の大きなリスクとなっている。"

New blog post: PF Firewall on FreeBSD - A Practical Guide

After years of running PF across multiple FreeBSD servers, I've written up the patterns that work: macros, tables, brute-force protection, NAT for jails, and dual-stack filtering.

Covers everything from basic concepts to production configs, plus a sidebar on authpf for bastion hosts.

If you're running FreeBSD and want a firewall that's elegant, powerful, and actually understandable, PF is worth your time.

"I’ve 5 years of coding behind me and I’ve been able to vibecode in 45 minutes what I could not program in less than two hours. So here’s why people with 20 years of experience will soon be out of job"

Basically every article about vibecoding those days.

Or how to tell the world you still have a long way to go before understanding the difference between "writing code" and "developing".

NEW SERIES WHAT?

I've finally, finally made the first entry in a new series on YouTube I'm calling, "Technology Boy," in which I yap at you about computer things in the vain hope that it'll help folks feel better equipped to navigate the world as a digital citizen.

We're starting off strong with a PIPING HOT topic: URLs.

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: mstdn.social/@animefeminist/11

This is a very interesting article:

“Additionally, the over-idealization of Japanese culture can contribute to an inclination to defend Japan itself. [...] A concerning number of Western anime fans are willing to overlook Japanese atrocities to preserve a romanticized image of Japan.”

I run a small business and I would like to accept credit / debit card payments on my Android phone running

Does anyone know of an app or paired terminal which will work?

SumUp asked me to turn off Developer Tools, but still said the device didn't meet the security requirements for accepting payments.
They offer a Bluetooth paired card reader - but I don't want to spend £30 if it won't work with Graphene.
Anyone have experience *receiving* tap-to-pay on their GrapheneOS device?
