       | I've really enjoyed writing blog posts recently. Not only is it a

       | I've written as well.
       | 
       | And sort of in that same vein, I've been developing my own static

       | 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
       |

       | 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".

       | help people improve typing speed quickly.
       | 
       | It's very data driven and personalized. We analyze a lot of key

       | 
       | 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).
