- Java Code Snippets
The last post in the track is a reference rather than a lesson: the lookups you will make over and over, in one place. Every snippet here compiles as written against Java 21. Strings Numbers and parsing Dates and times Collections Iterating Streams Files Records, Optional and switch Async with…

- Hasura – Interview Questions
The questions Hasura interviews actually ask, answered the way you would say them out loud.

The questions that actually get asked, with answers that show understanding rather than recall. Mutable defaults, is versus ==, the GIL and what it does not mean, shallow copies, decorators, generators, and how to answer when you do not know.
- Python – Code Snippets
The short answers you keep looking up — read a file into a list, sort a dict by value, flatten a nested list, count occurrences, chunk a list, merge dicts, retry a call, time a block. Copy, paste, move on.
