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.

Install mutiple Erlang and Elixir with vfox
Theoretically, you could install any version that appears in https://github.com/erlang/otp/releases. Since it is compiled and installed from source, the installation process will take some time. When you see the following message, the installation is complete.

Why are there so many languages?
Funny that you should mention Erlang. Looking at the Github for Erlang, it appears that the source for Erlang is 16.8% written in C. I would bet these are not the least important bits of the whole thing. So, Erlang depends on C.

Erlang: More Optimizations in the Compiler and JIT
It looks more like some of the JIT improvements made it profitable to manually unroll some loops in the base64 module: https://github.com/erlang/otp/commit/a03cf1601605dee767cd9d5...

Mixing sync and async views in the same application
https://github.com/erlang/otp as far as I know. It's somewhat confusing and I honestly couldn't say exactly where the BEAM VM or OTP or ERTS (Erlang Runtime System) start and end. I've never dug into it. I just install Elixir and sometimes Erlang through the ASDF tool, which does all the compiling for me.
