TL;DR: Want to send encrypted email? Nylas N1 with Keybase.io could be a pretty good starting point. However, the Nylas encryption UX needs a little improvement: it doesn’t display PGP fingerprints, it won’t let you sign emails, and has some quirky bugs.

How fun these two weeks have been! StartMIT is a short introductive course to entrepreneurship. Students come in with ideas they want turned into reality, while an amazing panel of speakers tells them how to do it.

I had an .m4a file and I wanted to cut a one-minute chunk starting at second 156. Turns out you can easily use ffmpeg for this.

These are my notes from a quick workshop at Stony Brook University given by Professor Michael Bender and Professor Rob Johnson in May 2012.

I can’t write this article fully right now, but here’s a quick lesson I learned.

I’ve been using Google Photos to upload over a decade’s worth of photos that have been piling up on my external hard drive.

This is an updated guide on how to build and install Eucalyptus 3.3.0 on Ubuntu 13.04. I have tested these steps on a freshly installed & updated Ubuntu 13.04 machine on Sunday, July 21st, 2013. There is another guide here for Eucalyptus 3.2 and Ubuntu 12.04. :)

Recently, I’ve been spending my time up in the clouds (i.e. sunt cu capul in nori) messing around with Eucalyptus. Eucalyptus is an open-source cloud platform. In my experience, this means that you can download it from GitHub, compile it and then torture yourself trying to get it to run :) Here, I am presenting a short guide on building, installing and configuring Eucalyptus 3.2.0. To maximize pain, feel free to ignore everything I say below.

I’ve been using OpenSSL a LOT for work lately and I’ve learned some interesting stuff. Here’s a quick guide on how to encrypt and decrypt files using AES in CBC or CTR mode using 256 bit keys and 128 bits IVs. To do this, I used the EVP API in OpenSSL, which allows you to easily encrypt a file using any cipher of your liking.
