This year, I decided to start opening up the tarball of random utilities that's been accumulating on my machine for years: stuff42.tar.gz.

The first thing I cleaned up was TCL-Edit <https://gitlab.com/siddfinch/tcl-editor>, a small Tcl/Tk text editor I wrote a long time ago. After seeing the Rust clone of Microsoft EDIT, I realized the obvious next step was to build a Tcl/Tk clone of the Rust clone of Microsoft Edit. Recursion shouldn't be limited to code.

I also built a tiny URL system in Perl <https://gitlab.com/siddfinch/perl-tiny-url>, meant to run locally. The idea is simple: short URLs for internal/VPN resources per client. I usually spin up a small daemon (or container) per client and get a dashboard of links I use frequently or recently.

Security is intentionally minimal since it's local, which conveniently lets me ignore authentication and other responsible behavior.

Goal for the year: Continue to open stuff42.tar.gz, pick something, clean it up just enough, and release it, and not have it by the end of the year.

Might even choose a language that might even be described as "modern."

I absolutely love pre-1800 homes and am exploring a few ideas on how to help preserve and promote them. The main thing I'm working on to that effect is https://homelore.org

It's like a carfax but for your home, although the intention is more to create an interesting historical narrative that inspires people to care about the history of their home rather than as a tool for inspecting home issues before buying.

My target customer is realtors who want to inspire buyers to take on historic homes that may need a lot of work. Also home owners themselves of course.

This looks great and I'll probably order a report. A couple of small suggestions. First, the price is very reasonable, but I think you should be more open about what it costs -- maybe on the home page or at least the Order Report page. Second, I think you should tell what areas of the country (world?) that you can provide reports for, again on the main page would be great.

I agree on both points, thanks for the feedback.

“Like carfax but for your home” is a really interesting idea. So many homes are bought with little-to-no history beyond an inspection of questionable thoroughness.

If this became the norm, somehow, it would be a really helpful tool for both buyers and sellers.

I got a few ideas which will probably never get done at this point

1 - actual css static analysis -- consume html + css, and provide tooling to preview what properties are inherited given the context you're in -- what you're overwriting, what display mode you're in. If there's inconsistent display modes depending on where in the html you are.

2 - a reactive html scripting language which using html as the source of truth, and synchronizes html elements through their relationships to each other

i only have prototypes, and unfortunately given the climate i feel i am the only person who wants these tools.. but every few weeks i get to sit down and get some progress and that's nice

I am continuing to work on Kan [0], a dev-focused kanban board that works via plain text files in your repository. I am finding it really useful for solo projects, giving a really simple way to get per-project Kanban boards that I can sync via Git. Since it's local only, it's really snappy, and given the dev-focus, it can offer some pretty nice workflows with local hooks, customization, etc.

The other project I am continuing to work on is Rad [1], a programming language tailor made for writing CLI scripts. It's not for enterprise software, it specializes specifically in CLI, offering all the essentials built-in, such as a declarative approach to arguments and generated help (as opposed to Bash where you have to roll your own arg parsing and help strings each time).

I've been slowly hacking on game ideas on and off for the better part of a decade and I've finally switched tracks and trying to seriously build something full time

I've given myself 6 months

It's a bit scary basically 180ing like this but I figure if I don't try it now I never will

I've already started prototyping various ideas, and to be honest just sitting down and spending time doing this has been really quite lovely

One thing I'm finding fun is slowly unearthing what I actually find interesting

I started with messing around in minecraft and tinkering with rimworld-like game ideas, but I'm slowly moving away from them as I've been tinkering more and more

Don't get me wrong, I do want to revisit them at some point in the future, but I do find myself circling more around narrative, simulations and zachlikes

It's a bit of an odd mix and in some ways they look like paradox style games, but I'm well aware that taking one of those behemoths on is going to be a bit silly, so I'm trying to slim down until I get to a kernel that I actually find enjoyable tinkering with

A toy if you will

Currently I'm trying to work out if there's anything interesting in custom unit design, basically unpicking how games like rollercoaster tycoon's coaster design maps to stats like excitement ratings and seeing how that might mix with old school point buy systems

It feels like it might be small enough to be a good toy and I'm having fun tinkering with it, but I have no idea whether other people will xD

It might honestly be too niche for anyone and I've successfully optimised for an audience of one :shrug:

I’m working on a 2D top-down Zelda-style adventure MMO game. I’m imagining it as a persistent world with Minecraft-like building and procedurally generated quests. I’d like to focus on co-op adventuring and social rather than pvp. Kind of a D&D experience I suppose, though that’s not really a direct inspiration for me.

I have no illusions that this is actually something in capable of building to an actual release-able state but it’s fun to tinker with.

Duralade - a programming language for durable execution (but has many neat aspects)

Most of the work as of today is in a branch, can see the language spec at https://github.com/cretz/duralade/blob/initial-runtime/docs/..., and some samples at https://github.com/cretz/duralade/tree/initial-runtime/sampl....

May not amount to anything, but the ideas/concepts of this durable language are quite nice.

I'm curious what advantages this has over adding durability to an existing language, like DBOS does:

Modern languages are not safe enough nor are they very amenable to versioning, serialization, resumption, etc. It makes sense for modern durable execution engines to meet developers where they are (I wrote multiple of the SDKs at Temporal, including the Python one, this is just a fun toy side project), but a purpose-built language that has serialization, patching, wait conditions, kwargs everywhere, externalizing side effects, etc, etc, etc is a big win vs something like Python.

Admittedly the lang spec doesn't do a great job at the justification side, but the engine spec adjacent to it at https://github.com/cretz/duralade/blob/initial-runtime/docs/... that has sections showing CLI/API commands can help make it clearer where this runtime is unique.

Fascinating, thanks for the info!

I built a simple joke tool to analyze all the rejection emails (over 1600) that I got during the recent job searches and create simple bar graphs from it. Wrote a blog about it https://github.com/khante/l here https://rohankhante.substack.com/p/thank-you-for-your-applic....

PS - The results are entirely obvious.

On my first game on Steam https://store.steampowered.com/app/3582880/Reprobate/

No unity, no engines. Only a custom homemade engine https://github.com/willtobyte/carimbo

Rewriting the backend Bitwise Cloud, my semantic search for embedded systems docs Claude Code plugin from Python to Go.

The problem was the ML dependencies. The backend uses BGE-small-en-v1.5 for embeddings and FAISS for vector search. Both are C++/Python. Using them from Go means CGO, which means a C toolchain in your build, platform-specific binaries, and the end of go get && go build.

So I wrote both from scratch in pure Go.

goformer (https://www.mikeayles.com/blog/goformer/) loads HuggingFace safetensors directly and runs BERT inference. No ONNX export step, no Python in the build pipeline. It produces embeddings that match the Python reference to cosine similarity > 0.9999. It's 10-50x slower than ONNX Runtime, but for my workload (embed one short query at search time, batch ingest at deploy time) 154ms per embedding is noise.

goformersearch (https://www.mikeayles.com/blog/goformersearch/) is the vector index. Brute-force and HNSW, same interface, swap with one line. I couldn't justify pulling in FAISS for the index sizes I'm dealing with (10k-50k vectors), and the pure Go HNSW searches in under 0.5ms at 50k vectors. Had to settle for HNSW over FAISS's IVF-PQ, but at this scale the recall tradeoff is fine.

The interesting bit was finding the crossover point where HNSW beats brute-force. At 384 dimensions it's around 2,400 vectors. Below that, just scan everything, the graph overhead isn't worth it. I wrote it up with benchmarks against FAISS for reference.

Together they're a zero-dependency semantic search stack. go get both libraries, download a model from HuggingFace, and you have embedding generation + vector search in a single static binary. No Python, no Docker, no CGO.

Is it better than ONNX/FAISS? Heck no. I just did it because I wanted to try out Go.
