Simplification of my digital self. Removed most of my online accounts. Removed all my VPS's. Removed most apps from my phone except core ones. Cancelled a lot of online subscriptions.

In the real world finally moved everything to USB-C. Gave all my old cables away. I have two chargers in my home and a handful of C to C cables. Everything connects to everything now.

Home is now downgraded to a dumb home. Lights work on physical toggles. No hubs or sensors anywhere. Heat and AC is with a dumb panel on the wall.

It feels freeing.

On my weekends I am working on yups. It started as Your Universal Package Straw-boss, but now it is going to Your Universal Prompt Straw-boss :)

It is very stupid for now but I am working on the process and a friend of mine is working to improve the LLM (that's the project Babelfish).

I am working on two things.

The first is a customizable digital math workbook. Currently the demo covers fourth grade math. There is a practice mode where you can select the skills you to want practice. There is also a customizable dashboard where you can setup your own widgets to practice math skills in different ways. I am working on some pre-made dashboards to help users get started. The next plan is to cover fifth grade math skills. My plan is to cover first grade math up to Calculus and High School Physics. I envision it as a companion tool for Khan Academy/Math Class/Math Books. Check out the demo. No signup required. Progress is only stored locally.

The second thing I am working on is an application to practice Cangjie. It's a Chinese input method that has been around for a long time. It is based on a visual decomposition of characters. Each character is represented by one to five codes and the majority are unique. My application teaches Cangjie like keyboarding (QWERTY) is taught to young students. You learn the location of the keys, then some basic words, then start typing sentences. I also have a free demo for it as well.

Feedback on either project would be appreciated.

Completely free, no ads, no in-app purchases and no accounts / network required offline voice transcription.

I have also built the macOS/Windows/Linux versions which I'll also make free to download and available on my site soon (https://blazingbanana.com/).

iOS version is built and works (extremely well), just waiting for the Apple Developer signup process to complete.

Big shout out to https://github.com/mybigday/whisper.rn and https://huggingface.co/ggerganov/whisper.cpp/tree/main for making this even possible.

Any suggestions are welcome.

A tool for K8S operators that replaces brittle imperative reconciliation code with type-safe state machines generated from declarative YAML definitions. It also bundles error handling / logging / metrics / traces for state transitions.

Not sure if I'm missing a better tool but trying to keep a good working mental model of this has been a nightmare for the operators I've maintained.

I'm building a yet another AI chat app.

My initial goal is to make a functional SillyTavern (AI roleplaying) replacement. SillyTavern builds prompts from a few rigid buckets (character, scenario, lore, system prompt, author's note...), which makes complex setups hard to manage. Content gets duplicated, settings have to be toggled in multiple places, and it’s easy to accidentally carry or modify state across conversations. Over time, it becomes difficult to tell what context is actually in effect.

I’m building an alternative that treats context as small, reusable pieces that can be composed and organized flexibly, rather than locked into fixed categories. Characters, settings, and behaviors can be mixed, reused, or temporarily enabled without duplication or manual cleanup, and edits preserve clear history instead of rewriting the past. The goal is to make managing complex context deliberate and controlled instead of fragile.

Although I’m trying to get the functionality required for roleplaying done first, the app is generic enough for other AI workflows where fine-grained, explicit context control is an improvement over existing chat interfaces. Think: start a new conversation with an assistant and start checking off rules, documents, and instructions to apply to the chat. Regenerate responses with clarifications or additional one-time context layers.
