📢[New Article] - Don't Pollute Your Spring Boot Main EntryPoint Class sivalabs.in/dont-pollute-spr… #Java #SpringBoot

Folder structure with contexts and features *_controller.rb file name as an slice entrypoint is required to stick with the defaults

This is an easy entrypoint. It's actually a compilation of his most contraversial stuff, but very practical and accessible. It was my original entrypoint. a.co/d/09dOtqoQ

Codex: TLDR; It's saying what it won't do because that's what it WAS doing. "I’m going to fix the actual mess in the commit-relevant tests: remove fake system assertions by replacing them with real product-entrypoint coverage, not by adding spies or changing product runners. Then I’ll run the system suite and leave any real product failures red."

i'm in the same spot tbh. most use cases i find are cli cron with a worse token bill. the one i use is one telegram entrypoint for everything, or an agent trying to pay for its own tokens

obvious answers here, but RE4 remake (or og too) or Dark Souls 3, i feel like both are the best entrypoint to their respective series (even tho i don't think ds3 is the best fromsoft game)

Not a huge fan of him, but this was a good album and was my entrypoint into his music.

If everything is reachable through a link you can't assume how your users are going to get to a specific point of your app For flows that requires you to go through screens in a specific order it's a problem You need to assume that every screen could be an entrypoint for the app so the data fetching should behave accordingly You can't assume that once the user is on a screen some data is going to be already fetched, an so you have to build, test and maintain more loading and error state UIs

They are trying really hard to have "an easy entrypoint for newcomers", while ignoring the fact that there is no newcomer that want to play a MMO anymore. The MMO crowd is finite and dwindling, and jump from one to another, and at this point, they all at least played WoW once.

You made the comparison with comics, and it's more relevant than you think, because comics too suffer from the same mindset of "we need a easy entrypoint for newcomers while ignoring there is no newcomers to comics anymore".
