Hiring is really hard. You’re not just hiring a “Rails Engineer” or a “Python Programmer” you’re hiring someone who can help you change the world. Tell them why! Talk about the hard problems you’re solving. 2/3 of these talks give ideas and insight into hiring from sourcing to actual interview processes.
Rewriting systems is hard. People think they are going to replace their broken down horse and buggie with a bullet train and this often ends up in disaster. Successful rewrites require an incremental approach that takes months/years and often runs way over schedule. 2/3 of these talks go over how to handle rewrites not only from a high level technical perspective but a cultural/management perspective as well.

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

This is a short writeup of a fun (but ultimately pretty useless) attack I implemented on the Nintendo Switch a few months ago resulting in the recovery of some otherwise unobtainable RSA public keys. Since public keys aren't private keys, this is pretty useless, apart from letting us validate some signatures on PC. Even so, the attack is a pretty cool one, so I thought I'd write it up.
Every Switch gamecart has a unique certificate (called its "CERT"), storing an RSA signature followed by some kind of unknown but unique encrypted data. I was trying to reverse how these certificates work, and the obvious first step was to try to see how they were validated. However, when I tried looking through the FileSystem (FS) module, which should be responsible for validating these certificates, I found no references to the format at all. The "CERT" magic number was nowhere to be seen, and I couldn't find an RSA modulus that validated the signatures I had. This was in
