Tar Usage / Cheat Sheet

Compress a file or directory

e.g: tar -czvf name-of-archive.tar.gz /path/to/directory-or-file

• -c: Create an archive.
• -z: Compress the archive with gzip.
• -v: makes tar talk a lot. Verbose output shows you all the files being archived and much.
• -f: Allows you to specify the filename of the archive.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Class vs. Dictionary; or, An Example of Space–Time Tradeoff in Python

Conclusions; or, tl;dr

What wins?

• struct-like objects, i.e. ones that are largely the same as a C struct instance, win in the memory department.
  • These tests do not try to determine what is best for very large sets of values, however; I direct the reader to http://stackoverflow.com/a/2670191 for an insight into that scenario when using a dictionary.
• Dictionaries beat out objects in access times.
• According to Wikipedia, the Python dictionary is highly optimised because it is used internally to implement namespaces. [citation needed]
