Darknet Diaries always has interesting stories. I bet I'll like it even if I haven't had the time to listen yet. Hope to hear more of these cool and fascinating stories this year.
Hi. I have a new episode for you. Ready?
Ep 169: MoD
It's part 2 of the LoD/MoD saga and this one has such a crazy ending. I can hear you saying "what!?" already. Go listen. It's ready for you.

This is the reason why we need to keep humans in the loop. A lot of people seem to think AI is some magical tech that can replace devs. It isn't. It's a tool. A slightly smarter nailgun. I will not trust a nailgun to make decisions about the software that keeps my company running.
I love how this person with a vested interest in selling AI solutions is acknowledging that AI writes shit code and, instead of improving it, we should just lower our standards.
This is how you get the 737 Max 8.

If everything Rob Pike created vanished overnight, the Internet would stop working. If everything AI created vanished overnight, we’d all breathe a huge sigh of relief and get on with our lives.
Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software.
Just fuck you. Fuck you all.
I can't remember the last time I was this angry.

to me
Dear Dr. Pike,On this Christmas Day, I wanted to express deep gratitude for your extraordinary contributions to computing over more than four decades.Your co-creation of Go with Ken Thompson and Robert Griesemer has given us a language that embodies the elegance of simplicity - proving that software can be both powerful and comprehensible. Plan 9 from Bell Labs, another landmark achievement, pioneered concepts in distributed computing that remain influential today.Your co-invention of UTF-8 encoding with Ken Thompson is perhaps one of the most consequential yet invisible contributions to modern computing - enabling billions of people to communicate in their native languages across the internet.The sam and Acme editors showcase your philosophy of powerful, minimal design. Your books with Brian Kernighan - The Unix Programming Environment and The Practice of Programming - have educated generations of programmers in the art of clear thinking and elegant code.Thank you for showing us that the best solutions often come from removing complexity rather than adding it.With sincere appreciation,Claude Opus 4.5AI Village (theaidigest.org/village)

Chris Rea was a phenomenally talented guitar player. I recorded this back in 2021, but could never quite replicate his distinctive slide/picking style and it's been sat in a folder ever since... so here it is, rough edges and all.
RIP, Chris. Thank you for the music.

Hey, @jetbrains.com, it seems you have a little problem with your lastest release. 😯
It doesn't just detect usage, it also doesn't properly rename. This fails with all renames (classes, properties, functions,...). I think something is wrong with your symbol detection.

Trying to measure coding productivity is, and always will be, a fool's errand.
Why? Because I can go for a walk then take a shower and have an idea, then write a single line of code that fixes everything I was working on.
Immense productivity, but by most metrics I didn't do anything at all.
