Repo focused on advanced knowledge, tips & tricks, debugging & fixes.

I'm gradually migrating my huge private personal knowledge base into this public repo.

Hit the watch button on the top right for updates.

Some of these pages are still in progress pending porting and populated yet from my private knowledge base pages,

some are stubs pending migration.

Much more advanced knowledge is captured in code and code comments. References to my major

[GitHub Repos](https://github.com/HariSekhon?tab=repositories&q=&type=&language=&sort=stargazers) are provided

throughout where relevant.

References to official docs and some classic books are provided for those who want to thoroughly cover the basics.

### Crypto

This section is probably the most financially important thing you'll ever learn.

- [Bitcoin](bitcoin.md)

  - more financially beneficial than your Tech knowledge

  - the most important knowledge along with avoiding

  [feminist divorce law](https://www.amazon.co.uk/Men-Strike-Boycotting-Marriage-Fatherhood/dp/1594037620/)

- [Crypto](crypto.md)

  - every day you're not in crypto you're losing money due to constant inflationary money printing by central banks and

  governments to fund budgetary deficits caused by universal suffrage spending liabilities

  - even many investments, which are also taxed and often confiscated by governments or ex-wives, are losing ground to

  inflation in real terms
