I keep forgeting this when need to flush the table in MySQL

SET foreign_key_checks = 0;

The easiest way to setup code diff on command-line I can found.

I modify it a bit so it works on MacOS X.

First, you need to install meld from homebrew.

Then create a shell script "svn-diff-meld" in ~/bin:

#!/bin/sh

# SVN Diff Wrapper for Meld

# KOG 2008-02



# This line is only need if you use it on MacOS, assuming meld installed by homebrew 

export PYTHONPATH=/usr/local/lib/python2.7/site-packages



left="$6"

right="$7"



meld "$left" "$right"

add alais to do svn diff w/ meld:

alias svn-diff='svn diff --diff-cmd=/Users/me/bin/svn-diff-meld'

I was in need for some shell magic to get the current NTP server IP address. After some Googling, found this:

ntpstat | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'

Saw a snippet in PHP doc, and applies it to display model validation error in cakePHP:

    $this->Somemodel->create();

    if (!$this->Somemodel->save($data)) {

      $errors = array_map(create_function('$key, $value', 'return $key.":".$value;'), array_keys($this->Somemodel->validationErrors), array_values($this->Somemodel->validationErrors));

      echo ' - FAILED (rule: ' . implode(',', $errors) . ')';

    }

It's sort of obvious; To create a controller that has no model, simply:

        var $uses = array();

Yeah, we shouldn't need this piece of code anymore... but the world is not ideal.

var isIE6 = /msie|MSIE 6/.test(navigator.userAgent);

With this, then I can conditional deal with IE6 throughout my javascript.

I'm working on a piece of jQuery code that need to read a parameter from the current URL to perform work. First step is to read the URL. Here's how to do it:

url_path = window.location.pathname;

Another trick I saw a while back using mysqldump. This come in handy when you want to drop everything in a database:

mysqldump -u[uesr] -p[passwd] --add-drop-table --no-data [database] | grep DROP | mysql -u[user] -p[passwd] [database]
