Personally the coolest was the program I built for my fathers use on his job.

It was my first to be used commercially in the real.

That was a very big thing, I was 17 at the time an used turbo pascal 5.5 and he used it to compute how well all machinery was doing, they rented out diggers and other construction equipment to construction sites and manually compute this with a calculator took up to three days. (This was 1987 so there was not very many ready made programs for business, you often had to build your own)

With this program he had it done in around 30 minutes.

The next best was recently when I got my raft distributed consensus cluster server working. Its a little bit like zookeeper.
Building that purely from the research paper was rewarding but a bit of a challenge.

Im implementing kafka with little to no theory understanding. Now that i have finally managed to implement it Perfrctly, even started kafka, zookeeper and kafka-ui through docker compose and it works perfectly in the backend app, i can finally now see the power this technology withholds, and now i have even more understanding of how it (approximately) works, and Now I'm more willing to learn the theory to understand it under the hood.

Does someone else find it much easier to fuck around and find out when learning something new before being overbloated with boring dry theory?

I fucking hate theory. Any kind of theory. Its boring as shit. But now that i have gone through practical implementation of this and can understand how powerful backend i can build with it, Now I'd have no problems learning theory

Got my ActiveMQ-Zookeeper Replicated LevelDB setup finished! All provisioned with Ansible. so happy :) needed to share. anyone else like setting up high availability stuff?

I decided to delete Apache Zookeeper on my Windows system but I cannot delete

1)CreateTxn.
2)DeleteTxn.
3)SetACLTxn.
4)TxnHeader.

in "docs\apidocs\zookeeper-jute\org\apache\zookeeper\txn\class-use"

It should be easy to delete but Windows said it cannot delete the file. I try to delete using command prompt but it said access denied.
