One of the most common arguments you hear from fans of generative ‘AI’ is that it’s not plagiarizing people’s work, it’s just learning like a human learns. So I’m going to break down why that’s just not true, and why it can never be true, with the existing systems. 1/

I took a few pictures of all the critters I came across walking through a meadow on my way to work. I think they came out quite nice :) #nature #photography
A red bug with long antennas sitting on a bud of a pinkish flower. A brown argus butterfly spreads its wings in the sun. An essex skipper sits on a blade of grass. A bee sits on a pinkish flower.

Here are all the posters I designed for RustWeek 2025!

1. "Box" (Back tot the Future)

#rustweek #rustweek2025
The "Back to the Future" movie poster, but with the title replaced by "Box<impl Future>". On top it says "1.21 gigabytes". The license plate of the DeLorean reads "ENOMEM".

Generally we think of alt-text as the domain of those with accessibility needs.

However alt-text is useful for many reasons, which benefit your viewers, as well as you, the creator!
An infographic. There are six panels. 1. "Slow internet. Alt text is shown in place of unloaded images." a drawing shows a phone with poor signal, and alt text is visible where the image should have loaded. 2. "Findabillity. Alt text helps to search content." A drawing shows someone searching 'dog with banana' and a post is shown underneath without the words 'dog' or 'banana'. It is implied to be part of the alt text. 3. "Screen readers. Alt is read out to people using text-to-speech software". There is a drawing of the output a screen-reader would show when viewing an image with alt text on bluesky. 4. "Translation. Alt text can be translated". A drawing shows a post being translated. The alt text is also translated into german. 5. "Readability. Text in images can be made legible" There is a drawing of some truly awful handwriting inside a speech bubble. The alt text clarifies what the text is supposed to say. 6. "Disambiguation. Description helps clarify intent." There is a drawing of a post with a picture of a creature. This is styled after the famous optical illusion of a rabbit and a duck. The alt text clarifies that the animal is a rabbit. It definitely looks more like a duck.

One of the most consistently neglected parts of today’s user experiences is our handling of errors. We’re so busy designing the happy paths through our products that we often forget to give the same care and attention to the times when things will go wrong

Would you use a program for #macOS that show which processes are listening on which ports?

I sometimes find myself in the situation that a process has not been stopped correctly but can't remember the command to find it.

#mac #dev
A MacOS application that shows a list of running processes and which port they are listening to.

My GPU has 45 billion transistors in it.

Like, we have this magic rock that we carved 45,000,000,000 miniature switches on it to create images of worlds that do not exist on a screen.

We really, really not appreciate enough how insanely magical technology is.

Using ariadne (github.com/zesterer/ari...) helped me spot an off-by-one error in my tokenizer! Seeing data structure visualized this way can really help. Check out ariadne if you are into #rustlang.
A snippet of code, annotated with lines pointing to different tokens in the input. Each line shows the type of token and span where it was found in the input.

Merry early Christmas! I wrote a new blog post about compiler optimizations in #rustlang I stumbled over while doing #adventofcode.

I propose we replace semantic versioning with pride versioning
Diagram with large number: 2.7.123 First “2” is commented: Proud version. Bump when you are proud of the release Second “7” is commented: Default version. Just normal/okay releases Third “123” is commented: Shame version. Bump when fixing things too embarrassing to admit

how do you all remember every UUID? I find it really hard. so I wrote them all down on every uuid dot com

the list has fast search across all 2^122 values (so you can find your favorites) - hoping to add some social features like "trending UUIDs" soon!

Having tried out bluesky for only a few hours: I think I like it. It has some nice features and is fun to use and explore. I might use it more than mastodon.
