10 years ago, I thought "programming is too hard, I'll make tools to make it easier"
5 years ago, I thought "I'll make a new language to make it easier"
now I'm working on tools to make "making new languages" easier 😂

Me: Do you want to have dinner now?
3 yo: No. I'm busy

3 yo: Mama. You didn't get me food. You NEVER get me food. It's been FOREVER
I had already prepped their dinner and it was on the dining table

Yep. Prestige podcasting is dying for the same reason as the rest of the media: Pontificating is cheap and reporting is expensive.

I really hate the term "sideloading". I preferred the original term, which was "installing software on a computer that you own"

Is somebody training an LLM to turn CS Paper algorithm descriptions into runnable code? That would be so cool.

AI is for writers who don’t like to write but want to have written, and readers who don’t like to read but want to have read.
Into the sea with the whole miserable joyless fucking lot of them.

People are reading AI-generated synopses of books and then claiming they read 100 books in a week. This is how the abolition of books began in Fahrenheit 451: classics were condensed into five-minute summaries for those too busy to do the reading. Later came the burnings.

My least popular (and most correct) view is that cars should be automatically limited to the local speed limit. Put the pedal to the floor and you still can't go over 25mph in a residential area.

There is no possible justification for limiting e-bikes to 15mph but not cars.

By now, you know that LLMs take TEXT and turn them into NUMBERS...somehow.
But how does it actually work?

You won't need to itemize nth-child to style things like staggered animations anymore 🥳
For example, I'd be able to clean up the angle position and animation delays in this demo: codepen.io/una/pen/Qwwz...

The Grace programming language now natively supports a Key type for managing API credentials. The benefit of a distinct type is:
- Grace guarantees that values of this type are never rendered
- The Grace browser obscures form inputs of this type
- Grace guarantees that values of this type are never rendered
- The Grace browser obscures form inputs of this type

IN CONCLUSION (finally) a desert or dry prairie grassland does not need to be made into trees! It’s pulling its carbon weight just fine! Respect the grassland! Respect the desert! It is not a slacker! It is doing big shit on way less water, and we should work with it, not against it.
