Check out this paper from my friend Ronen, and Prof. Fateman, putting Lisp into Excel: "A paper written with Ronen Gradwohl on Lisp and Symbolic Functionality in an Excel Spreadshe…

I'm late to the game, but I'm surprised that no one has mentioned StaticMan yet: https://github.com/eduardoboucas/staticman Just uses Git(Hub|Lab) to triage and approve comments fo…

Reservoir sampling in a few lines of awk: https://github.com/taltman/scripts/blob/master/EDA/samp It's shorter than this ruby implementation, and includes copious documentation, fi…

For those who might want a fuller description of IBM's active facilitation of these kinds of crimes, you should read Edwin Black's book, "IBM and the Holocaust". Those tattoo's on …

> An intelligence agency that keeps a list of demographic minorities for the purposes of spying & persecution is Holocaust-precursor-grade stuff Exactly. And that's how Jacob Appel…

I used blueproximity successfully with my Linux laptop. I bought the smallest bluetooth headset I could find ($25), removed all extraneous parts, and carried it on my person (not m…

This is a great exercise of how to take a Unix command line and iteratively optimize it with advanced use of awk. In that spirit, one can optimize the xargs mawk invocation by 1) G…

KEGG filters at the MAP or MODULE level, but it merely highlights the enzymes of the mosaic MAP/MODULE that it inferred is present in the organism, rather than display the subset o…

A problem with these wall charts and the KEGG diagrams is that not only do you not know which enzymes or pathways are active in which tissues within a single multi-cellular organis…

Using Pathway Tools, the pathways are automatically laid out for you in a rational manner, organizing pathways and super-pathways based on a manually-curated ontology. For example,…

The Roche Biochemical Pathways charts were the inspiration for the MetaCyc family of pathway/genome databases, all enabled by the Pathway Tools software (itself written with 400,00…

It's not exactly macrology, but here's a page on functional AWK: http://awk.info/?Funky

I love using gawk for slicing and dicing huge data files. The performance and conciseness of an AWK script is hard to beat. For those interested in general resources related to AWK…

Notice how they cherry-pick among genomes to get their fitted line. A common fallacy is to associate genome size with the "complexity" of an organism. Even assuming that there is a…

Whether vanilla TeX supports this out of the box or not, the TeX technology stack (including MetaFont and friends) has intimate knowledge of the size and shape of all glyphs. It is…

TeX uses a dynamic programming algorithm to perform its advanced hyphenation, which allows the text to fill the page "beautifully": http://en.wikipedia.org/wiki/TeX#Hyphenation_and…

You can think of Eshell as a Unix shell that is 100% customizable, and those customizations are done in a very high level language like Elisp, not in C. Sometimes it's great to use…

In case anyone is interested, I've extended this code and put it up on GitHub as a script called 'samp': https://github.com/taltman/scripts

Looks like a valid sample to me. Are you bothered by the ordering of the sample members? Then I'd continue the pipeline to include a call to shuf.

As minimax stated, your awk code won't provide exactly k samples. Here's a bit of awk code that implements reservoir sampling (apologies in advance for any bugs) and prints the cur…

I don't understand why the data is unstructured, and thus SQL is not an option. Isn't the data coming in from calls to the company's own API?
