Ordered key sharding in DynamoDB
So, you want to keep a sorted index in DynamoDB, but for whatever reason – usually throughput-related – it won't fit on a single partition. What do you do? Today, we look at the available solutions, do the math, and find out which is best.

DynamoDB crash course: part 1 – philosophy
This is part one of a series covering core DynamoDB concepts and patterns, all the way up to single-table design; the goal is to get you to understand idiomatic usage and trade-offs in under an hour. Today, we're looking at what DynamoDB is and why it is that way.

If you are preparing for interviews or want to know the nitty-gritty of LRU cache you should read this. Long but a very good one. @_andgravity explained stuff amazingly with code & test cases.

the only advice i've found worthwhile is "the important things aren't as important at first, you can learn them as you need them", "if you're not having fun you'll probably get bored", and "learn what your friends are using because you can ask them questions about it" shrug

#Python 3.12 factlet: There is a new itertool called batched() for grouping data into equal sized batches (with a possible odd lot at the end).
Interestingly the corner cases of "batched(iterable, 1)" and "zip(iterable)" both give the same result.

If all goes well, tomorrow #Python 3.12 will be released as final :-)

“Four different learning styles” has been debunked, but learners still have to learn how they learn, and choose the paths and materials that are right for them.

TBH, I'm having a lot of trouble teaching people that aren't internally motivated. So, at a meta level, this: Be patient, it takes years. But, like most things, it does get better with practice, and that is something you have control over.

For a total beginner, I'd still start with the tutorial, but probably couple that with something like making a tiny game e.g. with Pyxel, so they can get motivating results sooner. github.com/kitao/pyxel
