git hook to run a command after `git pull` if a specified file was changed.In this example it's used to run `npm install` if package.json changed and `bower install` if `bower.json` changed.Run `chmod +x post-merge` to make it executable then put it into `.git/hooks/`.

Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Bare minimum Chrome extension to inject a JS file into the given page when you click on the browser action icon. The script then inserts a new div into the DOM.
// this is the background code...
// listen for our browerAction to be clicked
chrome.browserAction.onClicked.addListener(function (tab) {
// for the current tab, inject the "inject.js" file & execute it
chrome.tabs.executeScript(tab.ib, {
file: 'inject.js'
});
});

KeePass v2.x (KDBX v3.x) file format
Convention: Byte array notation as it would appear in a hexeditor.
= Layout=
KDBX files, the keepass database files, are layout as follows:
1) Bytes 0-3: Primary identifier, common across all kdbx versions:
private static $sigByte1=[0x03,0xD9,0xA2,0x9A];
2) Bytes 4-7: Secondary identifier. Byte 4 can be used to identify the file version (0x67 is latest, 0x66 is the KeePass 2 pre-release format and 0x55 is KeePass 1)

Instructions on how to fix npm if you've installed Node through Homebrew on Mac OS X or Linuxbrew

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

--set theFileContents to (read file "Users:n8henrie:Desktop:Reminders.txt") -- Change this to the path to your downloaded text file with your tasks in it! (Note the : instead of a / between folders) Or, just name them Reminders.txt and put them in your downloads folder
--set theLines to paragraphs of theFileContents
set theLines to {"task name 1", "task name 2"}
repeat with eachLine in theLines
tell application "Reminders"
set mylist to list "Your List Name"
tell mylist
make new reminder at end with properties {name:eachLine, due date:date "7/10/2014 3:00 PM"}
