| I've really enjoyed writing blog posts recently. Not only is it a
| great way to flex your writing muscles, but writing about a
| topic, unsurprisingly, helps you _understand_ that topic better
| too. I 've had great conversations with friends about the posts
| I've written as well.
|
| And sort of in that same vein, I've been developing my own static
| site generator that I eventually want to move my blog to. It's
| almost certainly going to be a worse SSG than every alternative,
| but it'll be mine and that's worth something in itself.
|
| Plus it's just been fun to make! I wrote some gnarly code to
| generate infinitely nestable layouts that I'm kind of proud of.
| It's the kind of code that's really cool but you can only code on
| a project for yourself, because if someone else had to debug it,
| they might say some pretty unkind things about you.

| I built a free USCIS form-filling tool (no Adobe required)
|
| USCIS forms still use XFA PDFs, which don't let you edit in most
| browsers. Even with Adobe, fields break, and getting the
| signature is hard.
|
| So I converted the PDF form into modern, browser-friendly web
| forms - and kept every field 1:1 with the original. You fill the
| form, submit it, and get the official USCIS PDF filled.
|
| https://fillvisa.com/demo/
|
| What Fillvisa does:
|
| - Fill USCIS forms directly in your browser - no Adobe needed
|
| - 100% free
|
| - No login/account required
|
| - Autosave as you type
|
| - Local-only storage (your data never leaves the browser)
|
| - Clean, mobile-friendly UI
|
| - Generates the official USCIS PDF, ready to submit
|
| - Built-in signature pad
|
| I just wanted a fast, modern, free way to complete the actual
| USCIS form itself without the PDF headaches. This is a beta
| version

| I've been working on "Next Arc Research" --
| https://nextarcresearch.com - a wrapper around my curiosity to
| understand how AI, compute, and capital might change markets by
| 2030.
|
| It's not a trading tool or product. More like a _weekly, machine-
| assisted research project_. Each cycle I run analyses on 120+
| public companies across semiconductors, cloud, biotech, energy,
| robotics, quantum and crypto. The framing is inspired by Emad
| Mostaque's _"The Last Economy"_ thesis -- the idea that when
| intelligence becomes cheap, the physics of value creation start
| to look very different. I originally built it for myself and
| retail investors in my family but I figure it could have more
| general utility so prettied it up a bit.
|
| The system uses large-model reasoning (GPT-5+ though I've also
| tested Sonnet, Gemini and Grok) combined with structured scoring
| across technology maturity, risk, competitive positioning, and
| alignment to AI-era dynamics. The output is static HTML
| dashboards, PDFs, and CSVs that track month-over-month shifts.
| I'm adding to it weekly.
|
| Mostly I'm trying to answer questions like:
|
| * Which companies are structurally positioned for outsized upside
| in The Last Economy?
|
| * How should I deliver the research so that it would have been
| actionable to someone like me 30 years ago?
|
| * What signals would help folks identify "the next NVIDIA" 5
| years earlier?
|
| The inference costs real $$$ so I've set up a Patreon that,
| hopefully, will allow me to scale coverage and extend the
| modelling and methodology. There is a free tier and some recent,
| complete example output on the web site. I'm also happy to gift a
| free month for folks willing to provide constructive feedback:
| https://www.patreon.com/NextArcResearch/redeem/CC2A2 - in
| particular I'm looking for feedback on how to make the research
| more actionable without drifting into "financial advice".

| Building the most effective typing application
|
| https://typequicker.com
|
| This is something that started as a passion project - I wanted to
| see just how effective of a typing application I could make to
| help people improve typing speed quickly.
|
| It's very data driven and personalized. We analyze a lot of key
| weak points about a user's typing and generate natural text
| (using LLMs) that target multiple key weak points at once.
|
| Additionally we have a lot of typing modes.
|
| - Code typing practice; we support 20+ programming languages -
| daily typing test - target practice; click on on any stat in the
| results and we generate natural text that uses a lot of that
| (bigrams, trigrams, words, fingers, etc).
