The keystore password on Java keystore files is utterly pointless. You can reset it without knowing it, as shown by this code. Note that private keys are still secure, as far as I know. The JKS implementation is copyright Casey Marshall (rsdio@metastatic.org), and the original source is available at http://metastatic.org/source/JKS.java. I've in…

Testing a pull request, then merging locally; and avoiding TOCTOU

It's not immediately obvious how to pull down the code for a PR and test it locally. But it's pretty easy. (This assumes you have a remote for the main repo named upstream.)

Getting the PR code

  1. Make note of the PR number. For example, Rod's latest is PR #37: Psiphon-Labs/psiphon-tunnel-core#37

  2. Fetch the PR's pseudo-branch (or bookmark or rev pointer whatever the word is), and give it a local branch name. Here we'll name it pr37:

$ git fetch upstream pull/37/head:pr37

Long Live CoffeeScript and Long Live ES6

Long Live CoffeeScript and Long Live ES6

Clearly ES6 is a huge improvement over ES5, and tools like [6to5][] allow us to use these cool features now. I was reading [Replace CoffeeScript with ES6][replace coffeescript] by [Blake Williams][] and thought it was a great summary of how ES6 solves many of the same problems that CoffeeScript solves; however I'd like to comment on a few of Blake's points and talk about why I'll be sticking with CoffeeScript.

Classes

Classes in ES6 (like many of the syntax changes in ES6) are very similar to the CoffeeScript equivalent. To support browsers that are not fully ES5 compliant (e.g. IE8-), however, we still can't really use getters/setters, so ignoring these the comparison is:
