agent-shell: stop spilling your outputs since the beginning of time, ai agents have wanted one thing at one thing only: redirecting stderr to stdout then piping the output to head or tail or grep or sed or awk. That’s all they really want. Except, they do it wrong the majority of the time (because “ai labs” are fundamentally incompetent at software engineering, as we’ve previously discussed before). Common ones I see routinely which are painful and require manual “reminders” into the agent to…

fancy slopping you here Slop has an intentional meaning which is more subtle than the common verbiage of the vernacular of the online disgruntled discourse cohorts: Slop presupposes a user of AI or some auto-generation method is using the auto-generated content, be it text, audio, video, vegetable, or mineral as a substitute for their own effort, work, output, judgment, taste, and style. but what if you aren’t using “ai slop” to substitute for your own ability, but to extend or enhance or…

claude-hooker The mystery of claude code over the past year and a half has been how does a world leading ‘AI productization lab’ continually generate such shitty amatuer globally distributed software and services over and over again? It’s almost like staffing a company entirely by 24 year olds seeing their net worth increase by $2 million per month for two years is a bad idea? Even the tech brain infosphere has noticed how claude code’s architecture is absolutely mornoic and amatuer and…

mattouch I’ve been using bettertouchtool for probably 15 years now, but only for two features: I bind fn+opt to window drag I bind fn+cmd to window resize That’s it. BTT has something like 3,000 features and all I use is two of them. So why not replace it? Say hello to MATTOUCH. Mattouch started out as a single-purpose mac menu bar widget to enable accessibility controls to capture mouse input to allow hotkey-based window moving and resizing.

macsetup - matt’s app config setup What do you do when you get a new mac? well, you probably run around and turn off all the garbage like: defaults showing ALL MY PRIVATE DATA in any spotlight search (??????) defaults using the BIGGEST FONTS AND LOWEST RESOLUTION POSSIBLE (????) defaults using slow key presses and slow key repeats (????????) entire computer sleeps when the screen sleeps (???????) intrusive MANDATORY DEFAULT “OS Tips” notifications For maybe 15 years now Apple has been growing…

Kvestigate - Investigate Kubernetes Clusters Ever find yourself given access to a piece of garbage kubernetes cluster and you need need to audit it to figure out what the hell is going on? Say hello to kvestigate your kubernetes investigation and auditing toolkit with the ability to even run ad-hoc workloads beyond the reach of the kubernetes scheduler allocator substrate system by just doing shit on the hosts themselves like computers are supposed to do.…

Converting exiftool to Python exifmodern We did it. I’ve been trying to do this on and off for five or six years now. exiftool is one of the secret foundational parts of internet media infrastructure. In the same way every video hosting site is just infrastructure laundering for ffmpeg, every photo hosting or image processing site probably uses exiftool somewhere in the background to get everything working consistently with as much high quality data extraction as possible. But there’s one shark…

claudo & claude prompt Claudo If you’ve used claude code you’ve probably seen (if you didn’t succumb to disabling seizures from the terminal flashing for 8 months with no fixes) it often creates and uses a “task list” to track progress and goals over time. We know our genius friends at anthropic can do no wrong because they have an unlimited supply of self-taught 24 year old “ai ethicists” all making $30 million per year and running around saying things like “you wouldn’t install only one…

H3 and Fixing ASCII Boxes Smaller updates today. H3 https://github.com/mattsta/h3 H3 has been either mostly complete, closed, or abandoned for a while, but there’s still room for improvement. I’m forking it here with my own refactors and improvements: https://github.com/mattsta/h3 Performance — the headline numbers Single-cell hot path API upstream → optimized speedup cellToBoundary 0.50 µs → 0.23 µs ~2.13× cellToLatLng 0.12 µs → 0.08 µs ~1.55× cellToVertexes (full ring) 19.5 µs → 15.1 µs…

Project Management System Continuing spring cleaning 2026 for day two brings us to: project management system. What is project management system you may ask? Project Management System (pms) is two things: uh, it’s a project management system (le duh) but pms is also an experiment in maximizing agent information density, discovery, and self-management surfaces. There’s also a very big 2,000 line README illustrating all commands and ideas for the project. or, you could even checkout a somewhat…

hyperdjango Following up from opsmas 2025 is spring cleaning 2026. Welcome! To kick off spring cleaning, the first project I’d like to release is: hyperdjango. What is hyperdjango you may ask? You could jump ahead into all docs at the hyperdjango hyperdocs hypersite and find out. Though, what you should be asking: what isn’t hyperdjango?

SaaS Delusions Walked so AI Psychosis Could Run For a while now, I’ve been trying to find a way to illustrate and convey how over-reliance on SaaS ruins companies and lives. These days you really have to inspect a company to see if they actually do something unique and valuable or if they are just 45 different SaaS subscriptions in a trench coat pretending to provide value you can’t just create yourself in a weekend. I think we can relate the recent growth of AI-adjacent mental disorders…

An Expert Review of A Fire Upon The Deep Over the years I’ve read A Fire Upon The Deep a couple times so here’s some stuff about it. I often see people get basic outright stated plot details wrong about it, so maybe this can be a cheat sheet if you believe it all. This page is in no specific order with no grand flow or purpose, so just relax and enjoy. (don’t @ me about his character model being wrong here) A Fire Upon The Deep is anchored in a future where the only notable surviving branc...
