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.

PHP: check dates
Carbon is probably one of the most popular vendors to handle dates in PHP.

Why was the Carbon library called that?

Calendar page displaying empty boxes and not days and numbers - $this->date
Let me start by referring you to PHP's DateTime implementation. There is a library called Carbon that uses this DateTime implementation and added almost all the methods you have (but better). So there really is no need to create your own just to be able to display Dutch names. That way to can get rid of the nasty "globals".

Need help formatting week day and time
first of all, i think you should use Carbon library. it's available here: https://github.com/briannesbitt/carbon
- Any help will be greatly appreciated

Do you use a DateTime wrapper?
See: https://github.com/briannesbitt/Carbon/issues/1693

Creating a Neat DateTime Helper Function in PHP
Working with datetime in PHP could be a real pain if you don't take advantage of popular libraries like Carbon. It's all good until you have to convert dates provided on user input into another timezone (eg. UTC) and vice versa. Other example could be that you have to manage various input datetime formats, and sanitize them into a consistent one before saving it to database.

Carbon - Float Difference in Months Filtered
Be careful of floatDiffInMonths() which can gives you a lower result (number of months in A < number of months in B) for an interval having more days (number of days in A > number of days in B) due to the variable number of days in months (especially February). By default, we rely on the result of DateTime::diff which is sensitive to overflow. See issue #2264 for alternative calculations.

The Great Concurrency Smackdown: ZIO versus JDK by John A. De Goes
Recently, CE3 has had similar issues reported across multiple repositories, almost an epidemic of reports!

Parallel streaming in Haskell: Part 1 – Fast, efficient, and fun
Thanks for the explanation!
So it's pull based and not push based like most other streams lib.
Does maybe someone know how this compares to FS2 or Iteratees than? (Both are also pull based streaming solutions).
https://fs2.io/#/
https://en.wikipedia.org/wiki/Iteratee
Looks quite similar to me. Is the Scala FS2 lib maybe even a clones of the Haskell solution? Or are they different in important aspects?

Should I Move From PHP to Node/Express?
On the contrary, switching to the functional mindset, with something like Typelevel Scala3 and respective cats and cats-effect fs2 frameworks, helps to rethink a lot of designs and development approaches.

Is Scala a good choice for a data intensive web backend?
fs2 for streaming.
-
Is “Functional Programming in Scala” 1st edition still relevant?
Finally, the last chapter has been rewritten to be based on some of the main design ideas from FS2 (https://fs2.io), which I hope will be more approachable than the 1st edition.

FS2 stream doesn't work as I expect it to
Just to clarify, is your doubt about the meaning of the api, or do you think you have found a bug? In either case, you can also open a Github discussion https://github.com/typelevel/fs2/discussions.

How to update and access state that needs to be shared across multiple API endpoints with FP?
Another more reactive solution would to use signals, as in FPR sinal network. fs2 implements this very nicely here https://github.com/typelevel/fs2/blob/8b285a6b54c63d43ed6aa3bb91365652035c90e5/core/shared/src/main/scala/fs2/concurrent/Signal.scala

Introducing effects systems S.A. ZIO at work?
Assuming the bug mentioned here is https://github.com/typelevel/fs2/issues/2568, we came up with a partial fix in a day (https://github.com/typelevel/fs2/pull/2569) and a complete fix in 2 days: https://github.com/typelevel/fs2/pull/2572. Note the original bug was opened on a Saturday. :)
