Certifying in AI Through the Company Whose API I Avoided
Five weeks of Google's Skills of Tomorrow 3.0, final exam today. I built hck_GPT offline — 102 intents, 9-layer routing, no API. This week: Maximized View Mode across every page + roadmap to v1.9+.
#10My Biggest Release, Then 48 Hours of Tester Bugs
v1.7.6 felt great for 12 hours. Then three testers spent 5+ hours each. 17 silent intents, psutil scanned 19×/message, CS2.exe topping charts for people who don't play it. This week: cleanup.
#9Building What 28 Real People Asked For
I asked what you'd ask an AI inside your system monitor. 28 answers came back (13 GitHub, 15 LinkedIn DMs). This week every single one becomes real code in hck_GPT.

Five Words That Teach the App What "Normal" Means
v1.7.8's thermal baseline starts with six lines: gaming, idle, light, medium, heavy. Once it knows the context, it learns what normal means inside it — for your machine, doing what it's doing right now.
#11The Bug That Worked Perfectly for 4 Months
snapshot() read live CPU/RAM/GPU flawlessly. Every module called it independently — 19 times per message, no errors, for 4 months. The fix: a 1-second TTL cache. 19 calls become 1.
#10Six Memory Depths, One Dictionary
The answer depends on how far back the AI looks. One dictionary maps each question to a time window — 5 minutes to 7 days — and two lines turn it into the AI's context.

Welding Plastics by Day, Deleting 1,326 Lines by Night
Maximized View Mode 100% done, chart tooltips 2.0, 1,326 dead lines removed, thread leaks fixed. The scar: months blaming tkinter for a slowdown that was my own bind_all on 8 pages.
#11A Quiet Maintenance Week That Lasted 36 Hours
Planned only bug fixes. Noticed a dead GT 1030 still in my registry → Ghost Drivers Hunter. Noticed idle apps burning RAM → Background App Hibernation. Two accidental features in a 'maintenance' week.
#10#151 in Poland and the Biggest Update of My Life
v1.7.6 live — 82 intents, DeepMonitor rewritten, a 2.5D component map, 373 process defs. The scar: psutil temperature reads returned None for months and passed every test because the function never ran.

A 2014 laptop at 94°C, a firing on December 22nd, and the monitor that came out of it.
