Canceling our @firefliesai subscription this week, because the software is pretty expensive for what it delivers. We built a better version with a few prompts. If anyone wants, we can open source it, just give me a comment. The product has no unique data, not many great integrations, all the features were sub-par so we ended up putting the transcripts out into Claude to have better features on top - and it didn't make sense that the recording-only software was so expensive.

iPhone Duo - they forced the slow launch in Czech, waiting 18 minutes to open the page. By opening the page it said last week in November, By the time I clicked through the form it was Dec 10 and by the time I finished my payments it was Dec 16-23... Oh well.... 2 months waiting time...

Just rode the Tesla FSD in Prague. I couldn't believe it would make a trip around Prague with no chaos. I mean, besides not letting one biker go who had priority on a roundabout - it was near perfect handling. Other car companies have to go FASTER... This is freaking great....

People use AI for search because Google Search just got so bad... Was just trying to look for 1 product yesterday - got 20 irrelevant sponsored ones, 5 sponsored posts, and after scrolling got a few bad pages... How did Google screw up its most valuable asset so bad?

German car engineers - can you start building smart home interfaces in a new, modern way, please? Is it so much to ask for my car to be smart and you building as fast as Tesla, or at least half the speed??
