Simple Progress (Load) Bar with jQuery

By David Luhman

Let's say you need to load some info into a page, but the info requires some time to process. You don't want to have the user staring at a blank screen during the processing, so first load the page with a busy (progress) bar image and then replace the image with the actual data when ready.

Assume you have this HTML page :


<html>
<head>
  <script type="text/javascript" src="/js/jquery.js"></script>
  <script type="text/javascript">
    $(document).ready(function() {
        $('#one').load('/one.php');

Cheap PHP lint checking with Git

By David Luhman

Running PHP's "built-in" lint checker (php -l) is a quick way to remove syntax errors which should never creep into your code.

However, you'll no doubt soon tire of typing "php -l" before every Git commit message, so why not let Git do the checking for you with a "pre-commit hook".

Travis Swicegood has a great article on how to set this up with Git :

I found you could pretty much copy his pre-commit PHP script and paste it into your .git/hooks directory with a couple caveats :

    Running Selenium PHPUnit tests against Firefox in an Ubuntu virtual machine

    By David Luhman

    As part of my Hudson CI server, I'm trying to run Selenium-based PHPUnit tests with each build. The build machine is an virtual machine (VirtualBox) running Ubuntu desktop.

    Initially, my tests weren't running thru Hudson and the associated build.xml file. This wasn't surprising since I had forgotten to start the Selenium RC server.

    Using the Hudson Continuous Integration (CI) tool

    By David Luhman

    I recently started writing some automated Selenium (Se) tests . I wrote a few tests, and Se seems to work well. But after writing a few tests, I found I needed an easy way to run, report, and track test results.

    This lead me to Hudson, a Continuous Integration (CI) tool.

    Hudson builds a given project and then does a number of useful things :

    • Automatically run unit tests and provide coverage reports
    • Show style, syntax, and complexity results

    Setting up Custom Coding Standards with PHP CodeSniffer

    By David Luhman

    PHP CodeSniffer provides you with some useful coding standards to get you going.

    This is nice, but how do you customize what's provided or set up your own standards?

    There is a tutorial on how to set up your own standards, but that was too much work for me at the moment.

    However, that is NOT the way to set up your own standards, in my opinion.

    Adding PHP CodeSniffer to your Hudson Phing Continuous Integration Process

    By David Luhman

    In a previous post, I described how to setup Hudson with Phing and PHPUnit for a simple PHP build process.

    Adding PHP CodeSniffer to Build Results

    Now let's expand on this a bit by adding PHP CodeSniffer (PHPCS).

    First, assuming you're still working on Ubuntu, install PHPCS :

    $ sudo pear install  PHP_CodeSniffer

    Add the Checkstyle to Hudson (Manage Hudson => Manage Plugins => Available).

    Installing Hudson, Phing, PHPUnit and Git on Ubuntu

    By David Luhman

    In this post, I'm just trying to get the simplest setup. I'll try to post details in a subsequent post.

    Here are three posts, in descending order, on this that I found useful :

    Preventing SSH timeouts

    By David Luhman

    Depending on the environment you're working in, you may be automatically logged out from a server by SSH timeouts. Here are a few things you can do to help prevent these timeouts :

    Add or modify the following in your /etc/ssh/sshd_config file :

    ClientAliveInterval 28800
    ClientAliveCountMax 28800

    In your ~/.bashrc file, set the TMOUT parameter to something longer. For example :

    export TMOUT=28800

    On your client (PuTTY) set the seconds between keepalives to something like 30.
