|

| specifically-styled print/PDF maps, such as what get installed at
| trailheads: https://github.com/c0nsumer/osm_to_ai
|
| This one takes GPS recorded rides and builds custom/personal
| heatmaps serving up the map tiles so I can use them in map
| editing software: https://github.com/c0nsumer/local-heatmap-tile-
| server
|
| And all of this has been put together to make the custom, local,
| specific-use-case maps that are at https://trailmaps.app (which,
| via local curation, are overall better mobile/online maps than
| many of the bigger auto-generated systems such as Trailforks,
| Gaia, RideWithGPS, etc, for visualizing local systems).

| All kinds of random stuff really, but to filter it down to only
| the noteworthy ones:
|
| Tuber[0] - this is my favorite, use it multiple times a week.
| It's just a little CLI wrapper around yt-dlp for my most common
| use cases - downloading the video, or the audio, or the subs. And
| then, if you've got the Claude CLI installed, it can also shoot
| the subs through Claude for a summary. I use it all the time,
| it's a great little thing!
|
| Scrapio[1] - this is really specific but I was so pleased with
| how it turned out. You give it a list of "hacks" ("mods" for
| Super Mario World) and it goes out to SMWCentral, grabs each of
| the patch files, and patches a clean ROM. I think I only used it
| twice but it was just a nice way to chew through a list of hacks
| and get a few ROMs ready, made quick work of something that would
| have otherwise taken a bunch of annoying schlep work.
|
| Lotus Eater[2] - calling this a tool is a bit undersell, but I'm
| still really pleased with it. It's a fan site for jamtronica
| greats Lotus that scrapes Nugs.net for setlist data and lets you
| do some mildly interesting analysis on things like song frequency
| and co-occurrence. Also has a per-user "shows I've attended"
| thing, Setlist Bingo. It's been fun to hack on.
|
| Lastly, less a tool, more just a toy: last week Google released
| their Magenta model for doing live music generation. I thought it
| was really neat, and it's open source, so I opened it up with
| Claude, and after a few passes and some extremely annoying
| toolchain issues, I was able to add a spectrograph which does key
| / chord analysis to the "Collider" app, so you get a live readout
| of "what the band is playing" and you can pull out your guitar or
| whatever and join the jam with some info at your disposal. It's
| the kind of thing that would have taken way too much effort to be
| worthwhile in the past, but with AI, it's a really neat result of
| a fun night of weekend hacking. See the README I added in my fork

|
| Then I run an ETL job on the json data I have downloaded, pre-

|
| It's very early days, and I only spend one or two hours a week

| is a link that can take you to the artist, composer,

|
| Unfortunately this is only useful to me, because I targeted the
| music I listen to.
|
| Next step is to download lyrics and extract song meaning,

|
| The llm-model-gateway companion plugin lets you serve models from

| itself be a consortium of models. e.g.
|
| llm consortium save cns-glm-n3 -m glm-5.1 -n 3 --arbiter
| mercury-2
|
| llm consortium save cns-k2-n3 -m kimi-k2.6:3 --arbiter mercury-2
|
| llm consortium save cns-meta-glm-k2 -m cns-k2-n3 -m cns-glm-n3
| --arbiter cns-k2-n3
|
| Yes, even the arbiter/judge can be comprised of a consortium of
| models, bringing parallel reasoning to the task of judging
| parallel reasoning chains.
|
| Consortiums can also now contain groups of specialists. These

| be randomized to inject some more entropy into the process.

|
| llm-alias-options saves inference parameters such as reasoning

|
| llm-prompt-json adds a --json flag to return the llm logs object
| (good for getting conversion_id, or reasoning output in scripts)
|

| Codex for most of this work but defined the protocol and
| everything upfront using protobuf (even though it's
| websockets). It helped with the "vision" and keeping the
| agent like Codex on the rails through completion.
|
| Once you have a pool (agents installed on your N number of
| linux machines), you can deploy apps (which are my way of
| saying, a container with a namespace) or you can deploy
| agents (which is my agent, custom made for this) that are
| assigned to a project. I decided Org structures are a great
| way to delegate workloads so that's how they are modeled.
| Projects provide the git repo, the docker registry for images
| and storage of artifacts, as well as the history of all the
| prompts the agents have done in the project. Useful if you
| want to go back and search through |thinking| tags to figure
| out the reasoning behind a decision.
|
| All of this was built in like maybe a month with Codex
| initially, until my agent was up to the task of coding w/ an
| endpoint configured (OpenAI API initially, now, NVidia DGX
| Sparks). What really works well is the delegation. The
| agent's have a webui that is exposed via the project urls so
| you can interact with the "scrum masters" of each project.

| the things I most need correct, like colleague names, customer
| names, internal product and architecture terms. I hand each

| it works a fixed routine: read the context file, read the

| master error table before drafting anything. Only the genuinely
| unresolvable handful surface as questions; everything else is
| corrected silently. Once I confirm those, it emits a cleanly
| formatted markdown summary in a manner I describe as a template:
| overview, topical notes, decisions, action items -- and pushes
| the work items into Todoist so commitments don't get lost.
|
| What makes it more than transcription cleanup is the back end and
| the feedback loop. Each summary hits Obsidian with YAML
| frontmatter and live Dataview queries, so open action items and
| meeting metadata behave like a database rather than static notes.
| In Cowork the whole accumulated Obsidian folder becomes fully
| queryable rather than merely searchable -- instead of grep-ing
| for a keyword, I can ask questions that reason across months of
| meetings ("what were Todd's table-stakes asks, and has anything
| shipped against them"), with the model able to look across
| separate conversations. The other half is self-improvement: every
| clarification I resolve gets written back into the context
| document: its people directory, terminology glossary, and
| especially the ASR error table, so a garble I corrected once is
| corrected automatically from then on. Over time that one document

|
| Like, okay, CPUs still get faster every year, and every now and
| then someone makes a breakthrough and we get a bump in speed from
| something. But when you write high performance code, you very
| quickly run into hardware constraints, like how fast information
| can move and how far away components are from the CPU cores
| themselves. People keep saying performance isn't THAT important,
| and that modern hardware is so fast and amazing, and that they
| struggle to even find a way to use all of their CPU cores and RAM
| with their little app or program or game. Yet here I am, writing
| code that will noticably speed up if I run it on a CPU with a
| little bit more L1 cache.
|
| This is similar to how it feels to program with AI when you're
| reasonably competent (to put it mildly; I avoid the 10x developer
| label because comparison to others is very silly). Everyone keeps
| saying it's getting so much better, and it's so good, and
| worrying about code quality and architecture is dumb because we
| can move so fast it doesn't matter. Yet here I am, writing code
| by hand because I tried doing it with AI a couple times and it
| just doesn't hit the mark.
|
| I'm not doing anything special, I just have high standards and a
| good amount of experience when it comes to software quality,
| performance, and maintainability, which is why I keep getting
| hired. I'm convinced that people who think their AI generated
| software is good are the same people who write short variable
| names and think it makes their software faster (hyperbole, but
| you get what I mean).
|
| I can feel when I hit the limits of the hardware, and I can feel
| when I hit the limits of LLMs, and I know for both of them that a
