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.

Just some random THOUGHTS from my reading these days.

Presenting all evidence as equally high-quality and equally robust is a bad implicit message. It takes a lot more work to contextualize, but contextualize we must. Listing a huge stream of studies with all kinds of different characteristics and wildly different theoretical framings isn't really a service to your reader. It teaches science = list of facts rather than a process of evaluating overlapping, changing, dynamic bodies of evidence

We re-launched our website at the Applied Social Media Lab, which is not very exciting except that

1) we have an announcement for Frankly, a newly open source project I helped (a little bit) with that builds some public interest infrastructure for deliberative decision-making asml.cyber.harvard.edu/2025/04

2) you can follow @asml.cyber.harvard.edu🦜 Home - Applied Social Media Lab at Harvard University to get updates here on fedi via the now-working RSS feed (or just use an RSS reader)

so after repairing that ps2 fat yesterday, i noticed that it wasn't playing back Ico properly. the disc would attempt to spin up for a half second, retry several times, then give up for good.

the disc was in perfect shape.

i noticed that it was a blue/purple bottomed disc, which made me curious. as it turns out, the blue discs are CD-ROMs. there are very few of them for the PS2, and then almost always cause read problems.

in the 00's teenagers figured out that if you put two pieces of masking tape on opposite sides of the spindle hole of a CD, the PS2 would read the game properly. i was perplexed by this, because i couldn't find any explanation of why the "tape trick" worked. was it shimming a gap between the disc and the tray?

as it turns out, a very young kid named Denzel explained it perfectly in his 16 year old 3gp cell phone video:
www.youtube.com/watch?v=iaaRs_

the problem is caused by a weak magnet used in the tray that hovers over the spindle. seen below, this white piece of plastic clamps down on top of the CD's "clamping area" (the perimeter of the donut hole). it is meant to both hold the disc level, *and* prevent the disc from slipping on the spindle.

since putting downforce weight/pressure on the spindle is a Bad Idea (motors don't love this), engineers embedded a magnet in the white plastic: when the plastic came close to the metal spindle, the magnetic forces sandwich CD between the spindle and white plastic. with enough magnetic grip, the CD wouldn't slip at all.

it works great for DVDs that spin at 4x.

unfortunately the PS2 engineers did not consider at least three things:
- playstation CD-ROMs are much heavier and more difficult to spin than DVDs, requiring more friction from the spindle.
- the CD-ROM in the ps2 spins at 24x. the motor goes into jet engine mode when it detects a CD. it needs *much* more sticky friction to keep that CD from slipping when the motor is sending your disc off into orbit.
- the cheapass fridge magnet inside of the plastic disc would lose their magnetism over time - due to various factors (EM fields, shock, heat). even a tiny percent change was enough to let a CD disc slip.

the solution? i stole a tiny strong button magnet from one of my fridge magnet toys. it very easily centered on the existing magnet, without needing glue.

this is information now buried in hundreds of shitty youtube videos and reddidiots *still* telling people to stick tape on their CDs.

okay so, trying to be charitable: does anyone know why eslint removed --ignore-path? or why it doesn't just respect .gitignore by default? because now you need like three lines of code to do what sort of should be a default option? am I missing something?

"We can show that increasing the number of trees by at least 30% could reduce the number of hours per year of extreme heat by nearly 64% and the amount of runoff by 58%, so trees can strengthen resistance to heat and flooding, especially in districts with high building density," Saha said.

The results of the two projects show that diverse green spaces with trees can improve human health in cities & mitigate the negative effects of climate change

Hi! 👋🏻 My name is Mitch (he/him), and I am an illustrator, graphic designer, creative director, brand director, and goober. I am currently on sabbatical from work, but I work in the tech industry, specializing in making clear, authentic brand stuff for things associated with programmers and sysadmins.

I am a practicing Bahá'í, and am very interested in conversation around things like comparative religion, pacifism, Linux, FOSS, where you're from, and what life is like there.

okay, yes, this entire approach to “ai” in the workforce is yet another instance of a tech CEO beclowning himself

at the same time: when a leader says human workers are a source of “bottlenecks”, and that automation is the source of “solutions”, pay very, very, very close attention

(and if you haven’t already, start getting organized with your coworkers)

Just got told relays are cheap and easy to run. Haven't heard that before.

Again, I just want a network where every govt and journalistic outlet (at least) can afford to run a piece of social media infrastructure such that whatever they want to tell the public, can go viral without the approval of any middleman company. Just like when they post something on their website or send an email. Adding "democracy of reach" to the "freedom of speech" the web gave us.

Reading opensource.org/blog/announcing and thinking about Sinn Féin's stance in Northern Ireland - they refuse to swear loyalty to the British monarch and so cannot actually sit in parliament, but people keep voting for them anyway. OSI seems to treat board elections as a purely practical mechanism rather than a way for their membership to express their desires, and their continued refusal to publish the actual election results means the desires of their membership remain unknown.
