Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Building a Streaming Platform in Go for Postgres
If you judge productivity by lines of code, absolutely.
https://github.com/Hello-World-EE/Java-Hello-World-Enterpris... is an excellent demonstration of this.

You probably should avoid putting lifetime parameters on traits
This reminds me of the "enterprise programming" mindset in OOP where people would make factories, strategies, strategy factories etc. just for the sake of it (instead of those solutions serving a real need) and ending up codebases that look like Hello World enterprise edition.

Simple Modern JavaScript Using JavaScript Modules and Import Maps
No other language or framework seems to get the same scrutiny as JavaScript.
The Enterprise Java solutions never seem to get as much discussion but we all recognize it also as being equally if not more so absurd[1]. This is true of every language and framework that gains mass adoption and use. Scala projects are crazy complex, the python 2 to python 3 migration was a mess, none of these are problems. They reflect the improvements in every metric to the underlying platforms and systems - end user experience, developer experience, reliability, testability etc.
JavaScript is in a phenomenal place today - we have come "full circle" but with better tooling, new capabilities, improved experiences etc.
There's a lot of keeping up with the jones' - that's partly nice as its job security and partly nice as a reflection of engineers improving our own ecosystem.

My first programming assignment was to print hello world, and my teacher said to always be very descriptive with my variable names. How'd I do? :D
It’s bad, but not as bad as the enterprise edition

Ever wondered why banking sites suck?
You might actually have to think about writing longass assembly hello world, but I can spin up fifteen Enterprise Java Hello World APIs in an afternoon.

Your death countdown begins... Your fav programming language decides your fate (read desc.)
Haven't written Java in years, but I'd take an enterprise edition program written in it, much like this one: https://github.com/Hello-World-EE/Java-Hello-World-Enterprise-Edition
- Well, that's one way of removing diacritic marks
- Personally I only listen to my boss complaining I make memes at work

What if null was an Object in Java?
Fortunately, Uber made tooling for languages with broken type systems

My Thoughts on “Bad Code”
Some patterns arise from language design
* You can't express `T` where `null` is forbidden in the type system so you get NullPointerException everywhere and defensive null checks.
* You express a sum type as a product type because your language does not have sum types .
* Your language doesn't have first class multiple return values (or tuples) so you return extra parameters via out parameters or thread local variables such as `errno`.
* Your language doesn't have exceptions (or algebraic effects) and can't do IO so you have monad transformers.
* Your language doesn't have set-theoretic types so you need hacks like `thiserror` .
* Your language doesn't have stackful coroutines or can't infer async IO for you so you have `async/await` spam or callback hell or "mono's".
* Your language doesn't have exhaustive checks (or pattern matching) so you need a fallthrough case check on switch statements .
* Your language doesn't have algebraic effects, so you need to pass context everywhere.
I know someone will reply about Java's null annotation checking options, so here is one of them: https://github.com/uber/NullAway .

Will Project Valhalla bring Kotlin-like nulls to Java?
If you must use Java, use Uber's Nullaway which gives null safety via Errorprone.

Does anyone have experience using this at Meta who can compare to https://github.com/uber/NullAway ?

How to use Java Records
A special kind of validation is enforcing that record fields are not null. (Un)fortunately, records do not have any special behavior regarding nullability. You can use tools like NullAway or Error Prone to prevent null in your code in general, or you can add checks to your records:
