I've just published 10 blog posts detailing the #Python Language Summit 2026. The Language Summit was held in Kraków, Poland and included discussions about free-threading, #Rust, garbage collectors, and type annotations. Please enjoy and thank you for your patience: blog.python.org/2026/09/lang...

“Big Walk” a cooperative game by House House (of Untitled Goose Game fame) is really, really lovely. I organized a group of folks, some who knew each other and some less so and we all had a lovely time 💜 Highly recommend this game if it seems interesting to your friend group. bigwalk.game #gaming

Hehe, I knew you'd be a fan of the full-cover artwork on the sleeves :) The plastic cases for the disks are also transparent, showing off the manual artwork. Clearly Nintendo was of the same mind on which region got better artwork, they used the Japanese artwork for the Thousand Year Door remake:

I didn’t realize until I was giving a tour of new purchases to my brother that I now own all regional variants of Pikmin, Pikmin 2, and (due to an eBay seller snafu), Legend of Zelda: Wind Waker! #gamecube #retrogaming #pikmin #zelda #gaming

You’d think that the King of Red Lions being on the disk would be a dead giveaway… but the Japanese revision of FSA includes Tetra’s Trackers and characters from Wind Waker! 😵‍💫

This project took longer because I had to reorder my Japanese revision on eBay, the seller for the first attempt had made a mistake that I also missed… see if you can tell the difference at a glance? 🙈 #gamecube #nintendo #retrogaming

Two boxes, manuals and GameCube disks for supposedly Legend of Zelda Four Swords Adventures +…. But the right disk is blue green and the left disk is green… the right disk is for LOZ Wind Waker not Four Swords Adventures!

Any #PikminBloom players out there? The arrival of Ice Pikmin means that collecting complete sets of decor within an event just got more difficult... 😬 I created a #Python script to simulate the number of seedlings required before and after the change. Read more: sethmlarson.dev/ice-pikmin-a...

Table showing the before and after Ice Pikmin percentage chances of completing a decor set for a number of seedlings collected. For example, if you collect 20 seedlings before Ice Pikmin you'd have a 70.4% chance of completing the set versus only 53.1% chance of completing the set with Ice Pikmin. This represents a 17.3% chance drop in likelihood of completing the set with this amount of seedlings.

Building a dataset about #Nintendo #Switch Online "Classics" collection, and now have approximate prices for each game in each collection. The #SNES collection alone is a wildly good deal. What sorts of questions would you like me to answer about this collection?

Table showing columns for Platform, Total ($), number of Games, and price per game. Table data is:

| NES | $1,980 | 91 | $21 |
| SNES | $3,600 | 83 | $43 |
| Game Boy (& GBC) | $1,615 | 41 | $39 |
| Nintendo 64 | $1,130 | 42 | $26 |
| Sega Genesis | $2,910 | 51 | $57 |
