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.

What Cannot Be Skipped About the Skiplist: A Survey of Skiplists and Their Appl
Skip lists are relatively simple to make lock-free, while lock-free (even unbalanced) binary search trees are an absolute nightmare.

Requiem for a Stringref
Here is the JDK 7 String#hashCode(), which operates on characters: https://github.com/openjdk-mirror/jdk7u-jdk/blob/f4d80957e89....
That's changed in the newer versions, because String has a `byte[]` not a `char[]`, but it was just fine. A hash algorithm can take in bytes, characters, ints, it doesn't matter.
In Java, you don't get access to the bytes that make up a string, to preserve the string's immutability. So for many operations where you might operate on bytes in a lower level language, you end up using characters (unless you're the standard library, and you can finagle access to the bytes), or alternately doing a byte copy of the entire string.
I admit, checksums using characters are a bit weird sounding, but they should also be perfectly well-defined.

Don't Share Java FileChannels
"AbstractInterruptibleChannel" seems to be doing this, and the comments/javadocs offer some hint. As to why they're designed this way, that's a good question.

Computer sucks at math
In Java, you could use BigDecimal. I linked to the source code, because it highlights the amount of complexity you get.

Default editor launched from AWT toolkit?
The windows implementation of AWT Desktop just calls the Win32 API ShellExcute function. This then quickly descends into questions such as "what version of windows do you have"; "does it correctly understand the difference between open vs. edit"; what does your registry currently contain"; etc.

Help with StringArray-changing function
ArrayList is a class, it is not an array. It stores two values. An array and its size. You can see this if you read the source code for ArrayList.

FreeBSD 14.0 Delivering Great Performance Uplift
Lots of great work by many people. But I bet this guy and his optimizations to the vfs and locking has made a significant impact.

FreeBSD 14.0-Release Announcement
Well there are some examples:
https://github.com/freebsd/freebsd-src/tree/main/share/examp...
But yeah that pf.conf could be expanded allot, but there are many source to cobble a conf together. My conf is massive but 99.9% commented out so i have my "template" for nearly everything, from mail to web to blacklistd etc.

Git cherry-pick and revert use 3-way merge
The BSD version is sort of very recent, for what it's worth -- FreeBSD imported a not fully functional version in 2017 and has seen more work on it in 2022: https://github.com/freebsd/freebsd-src/commits/main/usr.bin/... , but the default version shipped is still GNU diff3: https://man.freebsd.org/cgi/man.cgi?query=diff3&apropos=0&se... .
