January 13th, 2022: What did you learn this week?

It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.

Image of the brain

Feel free to comment with what you learnt and/or reference your TIL post to give it some more exposure.

Summarize a concept that is new to you.

And remember, if something you learnt was a big win for you, then you know where to drop it as well.👇👇🏻👇🏼👇🏽👇🏾👇🏿

Remix, the new React framework on the block, does use surprisingly few hooks.

That is refreshingly good to hear.

I enjoy using hooks, and at the same time think they should be considered more "low level" as there are too many ways to do them wrong and have really bad performance.

Is it faster than traditional react ?

Well, it's built on top of React, so it can't be faster.

But it seems to make some good decisions on when to render and download components.

Corporations should probably start supporting open source maintainers monetarily.

I don't condone Marak's actions, but can't help empathize. Open source maintainers I follow looking for sponsors don't get the kind of support they deserve.

I learned a lot about SQL/Postgres queries this week since I've been diving into @jeremyf's brilliant Forem home feed code. Being tasked to run with this has forced me to fill in some gaps in my knowledge.

Today I learn that PHP is hard

PHP was developed right at the dawn of dial-up Internet, back in the day where only ethernet cables transmitted server data. So yeah , it has chapters and chapters of literals , arrays, regexes and input evals!

Learning something can take time and that’s OK.

This week , I learnt that it is quite important to organise little workshops and 'hackathons' for development teams ! Teams are diverse 🤓🤠👩‍🌾🤡👩‍🦳🙇‍♂️ , some stay motivated and thorough, others have too much going on in their lives.

People of all ages are getting into development , but many of them don't have the technical experience or the C.S. perspectives to fit into the really demanding jobs.

These really demanding jobs require more than mere competence : they challenge your problem-solving skills🔹️ and your capacity for collaboration🔻. Managers are always presenting progress reports to their boards and facing all kinds of objections ⚠️🟨🧱🧱🟥.

Various compromises will be made in order to deliver on schedule, and some months later users discover lots of random crickets 'n buggies! 🦗🐜☘🦗🌱

👉General courses are fine at the outset - however newbies still need to experience following schedules and adapting to new sorts of workflows (i.e. Summer of Code , issues raised with Github Repos).
