why is python popular
python is pop only because circumstantial. and it's mostly because google. twice. once in y2k when google chose it, 2nd time in 2010 with machine learning fad.

R Melts Brains -- An IR for First-Class Environments and Lazy Effectful Arguments
The R programming language combines a number of features considered hard to analyze and implement efficiently: dynamic typing, reflection, lazy evaluation, vectorized primitive types, first-class closures, and extensive use of native code. Additionally, variable scopes are reified at runtime as first-class environments. The combination of these features renders most static program analysis techniques impractical, and thus, compiler optimizations based on them ineffective. We present our work on PIR, an intermediate representation with explicit support for first-class environments and effectful lazy evaluation. We describe two dataflow analyses on PIR: the first enables reasoning about variables and their environments, and the second infers where arguments are evaluated. Leveraging their results, we show how to elide environment creation and inline functions.

Copy Git Repo Dir to USB Drive
todo, work in progress
i have a git repo, of 20k small files. I need to copy it to usb drive. How do i compact the git so it's just few big files, and just copy over the .git dir?
alternative is temp move out the .git then zip the dir so i have 1 single file to copy. But, temp moving .git is tedious. also, zipping is time consuming.
I have a git repo, of tons of small files. I want to copy it to a usb drive. Only 32gb capacity. The problem is, my repo, is over 32gb. Because, having a .git double the size. Because it's the size of the .git plus the dir size. Also, transferring tons of small files is extremely slow. What i want, is some way, to make them 1 single binary file or just a few. So, i can easily copy. So far i do not have easy solution. One solution is, try to compact the git, then, copy over the git. On target i can git checkout. Second solution is, temp move the .git out. Then, either zip or tar gz the dir. This is also very tedious. Plus, either way, it's time consuming to compact git or zip/tar.gz. That's what i want to do.

git archive idiocy
The idiotic git archive command, creates a tar or zip that does not have a parent dir.
You get tar bomb when you expand.

The shape of the circumflex was originally a combination of the acute and grave accents (^), as it marked a syllable contracted from two vowels: an acute-accented vowel and a non-accented vowel (all non-accented syllables in Ancient Greek were once marked with a grave accent).[2][citation needed] Later a variant similar to the tilde (~) was also used.
