This gist will walk you through configuring your Node.js Project so that you can write your code in TypeScript using Visual Studio Code. These isntructions were written for attendees at Microsoft Build doing a super secret thing I can't talk about (ooo, the suspense!), but they also will work for any Node.js project written in TypeScript.

Before we get started configuring TypeScript, we need to initialize a new Node.js project. If you have not already installed Node.js, please head over to nodejs.org and install the latest LTS version of Node.js. Once this is done, create a folder for your Node.js project and open a terminal in this folder. In the terminal, run the command:

npm init

This command will ask you a series of questions. You can use the defaults for each question here because they don't really matter. These only matter if you intend to publish your module to [npmjs.com](htt

from streams session

• end-of-stream - specify a callback to be called when a stream ends (which is surpsingly hard to get right)
• duplexify - compose a Duplex stream from a Readable and a Writable stream
• pump - pipe streams together and close all of them if one of them closes
• pumpify - combine an array of streams into a single duplex stream using pump and duplexify
• through2 - tools for making Transform streams
• from2 - tools for making Readable streams

Subject: [PATCH] http: do not reuse socket on error responses

Some servers (in this case, CouchDB) behave very oddly when you attempt
to re-use a socket that returned an error response.

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5

monitoring: what I want

I've recently shifted from a straight engineering job to a job with a "dev/ops" title. What I have discovered in operations land depresses me. The shoemaker's children are going unshod. Operations software is terrible.

What's driving me craziest right now is my monitoring system.

What I have right now is Nagios.
