Anybody has experience using rasdr4? What is it capable of?

What’s up with Index in January 2023?

For update actually does block concurrent SELECT FOR UPDATES, so the article is correct

FOR UPDATE locks the row for other blocking transactions (including another select for update) The weaker form that only locks updates and deletes is called FOR SHARE. Transaction isolation levels do not make a difference here.

https://www.postgresql.org/docs/current/explicit-locking.htm...

So the article is correct that SELECT FOR UPDATE will ensure that another concurrent SELECT FOR UPDATE transaction never acquire the same row (it will block), though nothing prevents other non-blocking selects to query this row concurrently.

You can think of it as usual locks - only the threads that explicitly use the same lock have the mutual exclusion guarantees. If there’s another thread that does not acquire the lock and tries to access the critical section - it will be able to do so.

Actually I can relate to those misconceptions as a person who enjoys popular science.

I like articles like this since they hopefully help me to fine tune my intuition.

After using several bank clients in different countries I can confidently say that some banks just have bad UI, and other banks are just good enough. I don't think human language is simpler than good simple interface, though it can shine as a guide or navigator.

I love all the series about writing your own X in 100 lines of code. It gives you the understanding of technology and removes a lot of unnecessary details.

The great examples of this are 'A from-scratch tour of Bitcoin in Python' https://karpathy.github.io/2021/06/21/blockchain/ and 'Let's build GPT: from scratch, in code, spelled out' https://youtu.be/kCc8FmEb1nY from Andrej Karpathy

I wonder if anybody tried to collect all such projects together and built his own 'Internet in just 100 lines of code'

I'm Santa, not Satan!

Ok you got me, I feel nostalgic. What strikes me most is that those people from 90th were putting their creativity into something only handful of people will ever see, they were effectively shouting to void.

I would love to be still able to discover low-ranging websites like this. I remember somebody shared some alternative search engine?

Why? Is he trying to make the company profitable by keeping the traffic within it? But how many people will be freaked out instead?

Oh I found a golden card from Magic the Gathering

cmikec, how many operators do you have by now? and how many customers?

Can't wait to see screen version!
