River (getriver.com): Keep a programming journal.

One of my favorite past times is to look at the notebooks of famous scientists. Da Vinci's notebook is well known, but there plenty others. Worshipping Da Vinci like no other, I bought a Think/Create/Record journal, used it mostly to keep jot down random thoughts and take notes. This was great in the beginning, but the conformity of lines drove me nuts. Only moleskines made blank notebooks, so I had to buy one.

At the same time I started a freelance project. The project itself is irrelevant, but suffice to say it was very complex and spanned several months. It seemed like a perfect opportunity to use the moleskine. Looking back, all my entries fell under few categories:

  • Todo
  • Question
  • Thought
  • Bug
  • Feature

Operational PGP

This is a guide on how to email securely.

There are many guides on how to install and use PGP to encrypt email. This is not one of them. This is a guide on secure communication using email with PGP encryption. If you are not familiar with PGP, please read another guide first. If you are comfortable using PGP to encrypt and decrypt emails, this guide will raise your security to the next level.

Most VPN Services are Terrible

Most VPN Services are Terrible

Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.

This mini-rant came on the heels of an interesting twitter discussion: https://twitter.com/kennwhite/status/591074055018582016
