At BASSCOM AI conference in Sofia, Anthropic’s Patrick Dreisch delivers interesting insights now He says AI capabilities double every 7 months now

Vibe-coded a 2D orthophoto/3D point cloud viewer so I can share my drone-captured collections with friends. It supports WebODM exported assets.

My GitHub contribution stats before/after GitHub Copilot Pro subscription. What do you make out of it?

Vibe-coded an image diff tool with AI capabilities Available to test at https://imgdiff.harizanov.com/

Have not paid for EV electricity since late Feb, going purely on solar. More than 800km driven so far, feels illegal.

Emergency revival procedure started; vibe-coding session interrupted 🙁
So Cuba is next?

Today's 60 km EV commute's spent energy is fully recovered by free solar charging once back home. And it's still only February. Impressive.
Selling my remaining diesel cars, two BMWs, and going all-electric

Added a speed camera watchdog for the Tesla using live Waze report-scraped data. Implemented same-street filtering to drop false positives from nearby roads. Still far from ideal. Don't ask why I needed this.

Interesting AI model benchmarking at https://contextarena.ai/. I like how it visualizes the loss of attention as context increases – something many don't realize

Home Assistant dashboard on Tesla’s screen. Convenient.

Just finished setting up OpenClaw on a cloud VPS. I'll be chatting with it over a private Discord server/channel. I've set it to use anthropic/claude-opus-4-6, so it should be quite powerful. Fun times ahead. OpenClaw is burning through tokens like crazy. Had to revert to more basic models after shelling out $35 in three hours.…

Progress on home energy tracking, but many more devices still need to be added. Shelly EM-50 will help cover more of the untracked consumption
102% rise in gold price since Jan 1, 2025. This can’t be good.

Slightly over 5000 km driven with our new Tesla in the three months since we got it. The app estimates 625 BGN (320 EUR) in savings compared to an ICE vehicle. Actual savings are even higher, as 16% of the charged power is free PV produced at home.

Our heat pump spent 103 minutes defrosting today, with two more hours to go. Not ideal, but such days are rare. It's foggy outside, with temperatures around freezing.

Impressive Frigate performance optimization using Gemini. My Raspberry Pi 5 + Coral TPU setup handling 8 cameras has seen a 38% drop in CPU usage, despite increasing the detection frame rate from 4 to 5. Gemini made several smart suggestions, including generating a shell script to ffprobe camera streams and determine their characteristics, splitting and…

I've been running TeslaMate for about a month and am quite impressed by the detailed metrics it collects, especially the precise indoor and underground garage position tracking. I assume it's based on vehicle speed and wheel direction.

She’s efficiency queen, 2*C outside now, driving around Sofia, TM3 LR AWD

Just completed ESP32-based local BLE controls for my Tesla in Home Assistant using https://github.com/PedroKTFC/esphome-tesla-ble Experimenting with primitive GUI for the ESP32 Tesla remote

Too cold outside, Tesla won’t start. Any tips?

Our Mitsubishi Ecodan heat pump’s COP vs outside temperature:

7.4MWh solar power production at home in 2025, not bad

Our Tesla’s charging port logo’s green LED in the RGB died, so the logo is now purplish instead of white when idle and reddish instead of green when charging. Scheduled a free service replacement, but overall not cool.

Preparing for HomeLink: retrofitting actuators on the two doors we have and ordering the Tesla HomeLink module. The HomeLink module arrived today.Installation was easy. Very happy with it!

Created an n8n workflow that checks our electricity provider's site for planned downtime and notifies us ahead of time.

Can't get enough of that "free" EV charging 😉

New car—why not take it apart? 🙂 Installing Enhance’s commander and stalks.

This is confusing. What’s wrong, @Apple?

Picked up a paint thickness meter just because. Tried it on one of our cars – turns out it had a full repaint job, plus a little filler surprise on the rear door. Oh, well
