I just published my very first game made with PICO-8.

Like many beginners, I made a SHMUP. I think I made it my way, and I think it's cool.

Even though it's just a small game, a prototype, I want to treat it like a full-fledged game and polish it as much as possible.

If any of you happen to see this and take the time to try it, I'd love to get your feedback.

"AI can make mistakes, always check the results"

I fucking loathe this phrase and everything that goes into it. It's not advice. It's a threat.

You probably read it as "AI is _capable_ of making mistakes; you _should_ check the results".

What it actually says is "AI is _permitted_ to make mistakes; _you are liable_ for the results, whether you check them or not".

Except "you" is generally not even the person building, installing, or even using the AI. It's the person the AI is used on:

Inside the Systemd Age Verification Debate: Developer Responds to Criticism

A single pull request turned a quiet open source contributor into the unlikely target of one of the Linux community's most heated controversies. We interacted with Dylan Taylor to hear his side of the story.

It's FOSS

We REALLY need to reintroduce the Roman custom of Damnatio Memoriae—"damnation of memory", excision of a name and person from the written record: https://en.wikipedia.org/wiki/Damnatio_memoriae

I am 82 years old.
I have lived through the Cuban Missile Crisis, the JFK assassination, the Vietnam War, the Turmoil of 1968, Watergate, the Hostage Crisis, two oil crisis, disco, Reaganomics, 9/11.
The covid pandemic....
These past 11 months have been easily the most miserable era in America in my lifetime.
The hatred, the bigotry, the lies, the racketeering and pedophilia are beyond anything I have ever seen.
We are not going to hell as a nation.
We are IN hell.

On the positive side, if you want to abolish ICE, I can’t think of a more efficient way to make that happen than forcing the business travel class to interact with ICE agents on a regular basis

This High School Student Invented a Filter That Eliminates 96 Percent of Microplastics From Drinking Water

Virginia teenager Mia Heller’s filtration system harnesses the power of ferrofluid, a magnetic oil that binds to microplastics in flowing water

by Ramsha Waseem, March 20, 2026

Excerpt: "A few years ago, teenager Mia Heller came across an article in her local newspaper about ongoing water quality issues in her neighborhood in Warrington, Virginia. Tests had revealed that the water available for daily consumption was highly contaminated with PFAS and microplastic pollution. The article further reported that government agencies would not be providing any funds for filtering the water.

" 'It was up to people to provide their own filtration,' says Heller.

"Not long after the article came out, Heller’s parents invested in an advanced water filtration system at her home. The system, however, required constant upkeep. Seeing her mother replace the water filter #membranes time and again, Heller set out to find a better solution.

" 'It inspired me to design a filter without the use of membranes, to decrease the costs and maintenance needs associated with water filtration,' says the now 18-year-old student at Kettle Run High School. Through her school, she also attends a half-day program for math, science and technology at nearby Mountain Vista Governor’s School.' "

[...]

" 'It was essentially just a container,' she says. Within the container was her filtration system, what she called a 'spinning magnified vial.' Heller harnessed a reusable magnetic oil called ferrofluid to selectively bind to microplastic particles as water flows through her filtration system. While her model successfully filtered out the #microplastics from the water in two simple steps, the system still required constant maintenance, as it did not self-recycle the ferrofluid.

" 'But if I could create a system that was able to basically clean itself and #reuse material,' she explains, 'the maintenance needs could go down by a lot.' "

[...]

"About five iterations later, she found the perfect solution. Her current prototype, which is about the size of a standard bag of flour, consists of three modules. The first unit, about a liter in volume, holds the contaminated water inside it, while the second stores the magnetic oil-based ferrofluid. The core process takes place in the third module, which is much smaller. 'A magnetic field pulls the microplastics out of the water, and the ferrofluid is recovered and reused in a closed loop,' explains Heller. As a stand-alone filter (similar to a Brita pitcher), the system can filter about one liter of water at a time."
