I just completed "Laboratories" - Day 7 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/7
Our hero has skills.
My naive Part 2 iimplementation quickly ran into exponential memory allocation issues. After a rethink, though, I found a solution with sub-second performance. Fun.

I just completed "Trash Compactor" - Day 6 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/6
Well Part 2 was a bit more difficult than expected. Perhaps because I decided to assume UTF-8 input, rather than ASCII input.
Glad to have iter().rev() in the collection I was using.

Day 6, Part 1 is done! But Part 2 looks like the bigger challenge today; it is going to require a break and then some coffee.
Given the Star Wars references in today's adventure, I couldn't help but think: "There is no try. There is only do, or do not."

I just completed "Cafeteria" - Day 5 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/5
Glad to be done, but this took longer than it should have because a) i didn't read the specs carefully, and b) I was betrayed by my naive understanding of refs, ownership and lifetimes.

I just completed "Printing Department" - Day 4 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/4
This time my Part 1 solution was easily extensible to the Part 2 solution. And I learned more about Rust mutability rules and references and error generation and handling. Fun.

I just completed "Lobby" - Day 3 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/3
Just finished Part 2. This solution is the first one I'm not ashamed of.
I'm sensing a pattern: Part 1 code is a bit of a kludge, a bit messy. Part 2 is cleaner, perhaps because I add helper functions.

Part 1 took me a long time as I took the opportunity to learn about processing an input stream of UTF-8 data in Rust. Part 2 was interesting and just a bit tricky.

chesscom seems to be having performance problems or outages at the moment. I was able to play a bot game, but couldn't access the share feature to download the pgn, and the list of games isn't showing up under my profile. Parts of the site seem okay but much of it is not working.

A quite nice opinion piece by Emma Brockes about Elon Musk's recent "rage-fests" on X. It was fun to read and I think must have been fun to write. www.theguardian.com/commentisfre...
Elon Musk’s rage-fests on X make it clear that he wants something. I think I know what it is | Emma Brockes
The billionaire appears to have a David Brent-like desire to be seen as an entertainer. Please let him get back to conquering Mars, says Guardian columnist Emma Brockes

A couple weeks ago I changed my daily tactics practice from 10 puzzles per each of 7 themes to just 5 puzzles per theme. A good change -- I'm taking each individual puzzle more seriously, and thinking more carefully about the position. I may have found the quantity-quality sweet spot (for me).

Every day I try to a minimum of an hour of tactics. I use lichess tactics, 10 puzzles for each of these themes:
- Hanging Pieces
- Pins
- Forks
- Skewers
- Removing the Defender
- Discovered Attacks
- Double Check
Thinking about cutting it back to 5 puzzles each, because life. #chesspunks

I'm using the Dragon 1.0 engine (free to use), which is a successor to Komodo 14 and earlier. It's playing style and strength is very configurable, it also doesn't require a high-end graphics card, plays quickly, and doesn't cause the fans on my laptop to peg.

I'm playing against an engine that is tuned to be just slightly worse than me, and doesn't randomly blunder. It plays moves that humans might play. Next I'll try configuring it to be slightly better than me.

#chesspunks is there a way to hie text in a post? I'm thinking about posting puzzle solutions and wanting the moves to be hidden to avoid spoilers. You can do this in reddit and discord. Is it possible in bsky?
