Signing out on the LinkIn mobile app is the pitch blackest of dark patterns. But not once I’ve committed the move to long term memory!
Great read and I find this hard to disagree with bcantrill.dtrace.org/2026/09/05/t...

Any recommendations for a book I could read covering the 2001 dot com bust? Lately I’ve read “1929” and now “Too Big To Fail” both by Andrew Ross Sorkin. It’s been illuminating reading the parallels both historical and contemporary
I've been running CachyOS as my daily driver since January & it's been an excellent workstation setup. I can't live without ZFS/boot environments/optional root FS encryption/etc., so I've been maintaining an official installer patcher to help: github.com/fnichol/cach...
GitHub - fnichol/cachyos-zfs-installer: An installer that configures CachyOS with an optionally encrypted ZFS root filesystem, ZFSBootMenu bootloader, and automatic boot environments.

Ok, it's our little secret but…I'm decommissioning a VM that I deployed in April of 2009! Good 'ol Ubuntu 8.10. Honestly, it's amazing it's running anything of value still. Not for long though, time to say goodbye :)
Fascinating read of how NASA has advanced their computer systems from the Apollo era to Artemis era. Full systems determinism is a high bar and really bucks the trend for us folks working on systems down here in the dirt. cacm.acm.org/news/how-nas...

Of course I’m on social media: after checking feeds there’s a lot of porch erections going on
Watching the reentry of Integrity and splashdown this evening. It’s deeply inspiring to see what humans can accomplish working together using science, engineering, dedication, and training. A damn near *perfect* mission. #ArtemisII
LinkedIn: Algorithmic Confirmation Bias. My god friends, please be careful.
LLMs are currently the technologist’s Rorschach test, and it’s a lot
LLMs are trivially susceptible to “Don’t think of an elephant” behavior. Now all my agent files will only contain `Elephants.`
There's no better form of time travel than listening to the music of your teenager years.
Do companies not need people to build software anymore… or do people not need companies to build software anymore?
...the heck, a CLI? Well I mean, if you want to venture into my terminal, who am I to say no?
Obsidian 1.12 is now available to everyone! - Obsidian CLI - Bases search - Image resizing - Automatically clean up unused images - Better copy/paste into rich text apps like Google Docs - Native iOS share sheet
Technologists reflect: friction is not a universal liability, but rather a tool.
The first edition is one of my top favorite technology books of all time—cannot wait for this second edition. I’ll also say that due to how it’s written and the content being high level, the audiobook version is my top favorite technology audiobook.
The second edition of Designing Data-Intensive Applications, by myself and @chris.blue, is finished and sent off to the printers! Ebooks should be available in the next week, and print books in 3–4 weeks. Sigh of relief. 😅 (BTW, this is a good opportunity to support your favourite local bookshop!)
It’s official: I’ve wrapped up 6 years working with the best team of my career at System Initiative. I’d like to thank Adam Jacob, Mahir Lupinacci, and Alex Ethier for putting their trust in me and being their first employee hire. 1/4

Me: I need options to solve X LLM: Great idea! Here's options A, B, C, I prefer B Me: Hm, none of those are great, are you sure there aren't alternatives? LLM: Great point! There's a better approach in option D Me: D is still too strange... LLM: Right, I have a better solution: E! Me: ...
I just blew Claude Code's mind. At least, it's been over 6 minutes since I had an admittedly great idea & it's still "thinking". Human += 1
I still remain highly skeptical of blanket trust in & applications of LLMs but I'm finding an intentionally configured Claude Code with Skills leads to a powerful brainstorming & planning system. I haven't felt this generally creative in a long time & it's mostly due to "writing things down".
Last night I had a pretty vivid dream of playing the original Battlefield 1942. I remember when my friend showed me this game for the first time. I've never been so blown away by any video game experience as that day. It felt like anything in the environment could be manipulated and used.

State files drift, lock, and lie. Real-time simulation keeps infra accurate, collaborative, and safe to change. That’s @systeminit.com Read @stack72.dev 's post to help you realise the pain www.systeminit.com/blog/statefi...
State Files Are a Crime Scene
State files stall collaboration and punish refactoring. System Initiative fixes both with real-time simulation and change sets.
