Since this is on Hacker News and reddit...

No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is a good bit crazier.
I apologize for the use of _t in my types. I spend a lot of time at a level where I can do that; "reserved for system libraries? I am the system libraries".
Since people kept complaining, I've fixed the assignments of string literals to non-const char *s.
My use of type * name, however, is entirely intentional.
If you're using an older compiler, you might have trouble with the anonymous unions and the designated initializers - I think gcc 4.4 requires some extra braces to get them working together. Anything reasonably recent should work fine. Clang and gcc (newer than 4.4, at le

Tutorial: Meteor in Windows using Vagrant

BEFORE YOU CONTINUE:

Now, Meteor runs in any Windows without any line of this tutorial. Just download the Meteor binary! Yay!!
mrt is no longer used with Meteor 1.0

These days some people were discussing at meteor-talk group about running Meteor at Windows and I’ve recommended them using Vagrant. It’s a very developer-friendly piece of software that creates a virtual machine (VM) which let you run any operating system wanted and connect to it without big efforts of configuration (just make the initial installation and you have it working).

Many packages (I've tested) for running Meteor+Vagrant fails because Meteor writes its mongodb file and also other files inside local build folder into a shared folder between the Windows host and the Linux guest, and it simply does not work. So I've put my brain to work and found a solution: do symlinks inside the VM (but do not use ln. Use mount so git can follow it). It’s covered on

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Background

Security in a single CouchDB can only be set up to do either:

Everyone can read/write everything (admin party)
Everyone can read, some can write
Some can read everything, and those same people can write everything

So in the very common situation where you want user data to be private, the current best practice is to give every user a database. This sounds nuts at first, but it turns out that databases are cheap in CouchDB; Cloudant boasts that 100k databases in a single Couch is not uncommon (source).

	We’ve built a new communication protocol that sends messages with a restricted syntax.
	We need to write a function which determines whether a given message is syntactically valid or not.
	Here are the rules:

	1. There are 15 valid characters in the protocol: the lower-case characters ‘a’ through ‘j’
	and the uppercase characters ‘Z’, ‘M’, ‘K’, ‘P’, and ‘Q’.
	2. Every lower-case character in isolation is a valid message, e.g., ‘a’ is a valid message.
	3. If σ is a valid message then so is Zσ.
	4. If σ and τ are valid messages then so are Mστ , Kστ , Pστ , and Qστ .
	5. All other messages are invalid.
