Write a program in Ruby that parses a dictionary file for unique sequences of letters.

Requirements:

  • The program should generate two output files, "sequences" and "words".
  • The sequences file should contain every unique sequence of four letters that are unique and appear in exactly one word of the dictionary file.
  • Differences in casing should not reflect a unique sequence.
  • Numbers and special characters should not create a unique sequence.
  • The words file should contain the corresponding words that contain the sequence, in the same order, again one per line.
var randomNumbers = [42, 12, 88, 62, 63, 56, 1, 77, 88, 97, 97, 20, 45, 91, 62, 2, 15, 31, 59, 5]
func partition(v: Int[], left: Int, right: Int) -> Int {
var i = left
for j in (left + 1)..(right + 1) {
if v[j] < v[left] {
i += 1
(v[i], v[j]) = (v[j], v[i])
}
}

Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.

Principles we use to write CSS for modern browsers

Recently CSS has got a lot of negativity. But I would like to defend it and show, that with good naming convention CSS works pretty well.

My 3 developers team has just developed React.js application with 7668 lines of CSS (and just 2 !important). During one year of development we had 0 issues with CSS. No refactoring typos, no style leaks, no performance problems, possibly, it is the most stable part of our application.

Here are main principles we use to write CSS for modern (IE11+) browsers:

Editing Files Remotely via SSH on SublimeText 3

Editing Files Remotely via SSH on SublimeText 3

Sometimes you need to edit a file on a remote server, but using vim/emacs is not very practical, due to lag and speed of screen refresh.

TextMate users have the classic rmate, but it was implemented in Ruby, which may not be available on the remote server.

A better option is to use this version of rmate, implemented in pure Bash. It's a single file, self-contained, and with no external dependencies.

Step by step:
