Convert the giant blob of invalid JSON Robo3T gives you into something consumable.

First:
- Find... (?:ISODate|ObjectId)$("[^"]+")$ (BSON types)
- And replace with... $1 (the non-ignored capture group)
Second:
- Find... (/\*\s+\d+\s+\*/) (index comments)
- And replace with... , (comma to separate array elements)
Finally
Remove the stray comma where /* 1 */ used to be

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

Bash string manipulation cheatsheet

Assignment
Assign `value` to `variable` if `variable` is not already set, `value` is returned. Combine with a `:` no-op to discard/ignore return `value`.	`${variable="value"}` `: ${variable="value"}`

Get node binary (node.exe) from http://nodejs.org/download/
Create the folder where node will reside and move node.exe to it
Download the last zip version of npm from http://nodejs.org/dist/npm
Unpack the zip inside the node folder
Download the last tgz version of npm from http://nodejs.org/dist/npm
Open the tgz file and unpack only the file bin/npm (without extension) directly on the node folder.
Add the the node folder and the packages/bin folder to PATH
On a command prompt execute npm install -g npm to update npm to the latest version

Now you can use npm and node from windows cmd or from bash shell like Git Bash of msysgit.

	The Challenge
	-------------
	Given the following riddle, write a regular expression describing all possible answers,
	assuming you never make a move which simply undoes the last one you made.

	The Riddle
	----------
	You are on your way somewhere, taking with you your cabbage, goat, and wolf, as always.
	You come upon a river and are compelled to cross it, but you can only carry one of the
	three companions at a time. None of them can swim because this isn't THAT kind of riddle.
