ericwoo_kr Why I Ended Up Building This Instead of Using Something Off the Shelf The requirement sounded simple: let users drag vertices around on a 3D mesh, assign basic materials, and export the result as GLTF. My first instinct was to reach for something pre-built. That instinct cost me about two weeks before I gave up … Read more
The Real Problem: You Have an Idea But No Audience to Test It On The validation advice that gets shared most is written by people who already had an audience when they launched. “Post on Twitter, build in public, share your landing page” — great advice if you have 10K followers who trust your judgment. … Read more
The Setup That Made Me Actually Compare These Properly The thing that actually pushed me to take Kubernetes seriously wasn’t hype — it was a 2am deploy that silently murdered our Python worker and nobody caught it until a client emailed us at 8am asking why their background jobs hadn’t processed overnight. Six hours of … Read more
The Problem: My Bookmarks Were Useless Across Machines The thing that finally broke me wasn’t losing bookmarks — it was re-creating the same set of 40 links for the third time in a month. New client engagement, new VPN, new staging environment. Different URLs for the same tools I use every day. I’d pull up … Read more

The Problem That Got Me Here Fourteen hours. That’s how long our fluid dynamics simulation took per run using FEniCS on a 32-core machine. We were modeling turbulent flow through a complex pipe geometry for a client in the energy sector, and every time someone tweaked a boundary condition, the team had to wait until … Read more
Why I Stopped Using Google Calendar for My Team (The Specific Moment) The moment that broke my Google Calendar dependency wasn’t philosophical — it was a Friday afternoon email from a client’s IT security team saying their policy prohibited any data processed by Google Workspace. We had a team of eight people coordinating across two … Read more
Why I Stopped Relying on cPanel/WHM for New Projects The thing that actually broke my cPanel loyalty wasn’t a better alternative appearing — it was the October 2019 licensing change. Before that, cPanel/WHM ran on a flat per-server model. After? They switched to per-account billing, and the cheapest tier jumped to around $15/month for up … Read more
The Problem That Sent Me Down This Rabbit Hole The query that broke my patience was dead simple: filter a 500GB Delta Lake table by a bounding box — latitude/longitude range — and aggregate a few columns. Should have been fast. On paper, the data was “organized.” We had date partitions. We had Parquet compression. … Read more
The Actual Problem: NCERT PDFs Are a Graveyard of Unsearchable Knowledge A teacher in a government school in Rajasthan or Bihar has 40 NCERT PDFs sitting on a pendrive. She can open them, ctrl+F through them, maybe print a few pages. What she cannot do is ask them anything. A student comes up and says … Read more
