I was wondering how these kind of scenes were done in the movie Enter The Void back in 2009. Maybe they used different technique but looks very similar: https://vimeo.com/60239415

It’s the best time to start a company. Few people can build anything now. Big companies are at a huge disadvantage now because they can’t be personal. Software development is going decentralized. You can go to a bunch of businesses and be personal, and develop personalized solutions for them in person. You only need few such clients to be profitable and have lifestyle business.

Probably because DeepSeek creators were afraid government would just come and take it from them. The only solution was to open source it which is kind of a big middle finger to the Chinese government.

I was learning OS stuff and made a toy virus for myself back in 1999 and I thought it would be cool if antivirus officially recognized it so I sent a copy to antivirus company(Dr.Web. I think it was called?) and to my surprise now all antivirus databases have it and someone even has gif recording of machine booting up with it… so clearly they must be sharing not just db but also the executables etc

e9 — Mon, 06 Nov 2023 21:45:25 +0000

I think the dumbest thing in a lot of ETL is the API: - company collects data in database then creates API on top of - another company uses this API to put stuff into their own database waste of everyone's time, just share the relevant database or relevant dump in some way this will make everyone's life easier, this of course doesn't work for dynamic data

For this topic I recommend book called Shipping Greatness. The book has different sections for non technical people on how to work with engineers and how to work with designers.

On the other hand it is very positive because it inspires others in whatever “I am X” situation to get involved. It’s not uncommon for other fields like sports etc to have similar influence: “someone else like me is doing this so I can do it too!”

Those ‘small’ interactions maybe benign for you but where I grew up there was non 0% chance they’d take the phone and run away if I asked them to take photo. I don’t think you truly appreciate how much trust your country has.
