Wikipedia currently lists the following "Internet test frameworks" :

* HtmlUnit
* HttpUnit
* IeUnit
* Canoo WebTest
* Selenium

So IeUnit has made what could be called an "exclusive" list of web test frameworks. Of course there are plenty of other "Internet test frameworks" including Watir, Sahi, WatiN and even JsUnit and QUnit (for jQuery).

I wanted to turn an old laptop from a Windows XP system to one that dual-booted Ubuntu. To get this to work, I first had to resize my Windows partition.

I started out with Windows default disk defragmenter (Accessories => System Tools => Disk Defragmenter). I ran it a few times, but it always left files at the "high end" of the partition so I couldn't downsize the partition.

I then tried Defraggler (http://defraggler.com). This maybe is a bit better at defragmenting, but still left files at the high-end of the partition.

My own personal cheat sheet of useful Git commands.

diff

git diff --stat --staged (staged in 1.6+, cached in older)

Differences between HEAD and index (i.e., shows changes that have been staged)

git diff -U1 --stat

Reduces the context lines around differences to one line for shorter display. Puts summary (stat) at start of diff.

Here are especially helpful Git links :

**Git Index (Staging Area)**
Good layman's view of the index, along with great images of how add, commit, diff, push, fetch work.

**Git Cheat Sheet**
A bit laconic, but a comprehensive overview of most all useful commands, with reasonable examples.

As far as I know, BitKeeper does not seem to support the notion of "local" (intra-repository) branches.

Git supports these, and I've found them very useful. With Git, you can easily have debug/test branches without the overhead or config issues of an entirely different repo. I've even used one branch per bug so I can have several things in the air before merging them into the master branch.

The only way I can see to do this in BitKeeper is to have separate repos, which wastes disk space and adds the trouble of creating and managing separate directory trees in the file system.

I'm more familiar with Git and its merge process, but I also use BitKeeper and sometimes run into merge conflicts. Here's some info on how to handle them.

Unlike Git, BitKeeper doesn't have the notion of "local" branches, so all merges are from push/pull operations. BitKeeper has a merge command, but it's for merging single files, rather than merging one local branch into another.

Xdebug (http://xdebug.org) is probably one of the best ways to debug PHP code. But Xdebug can be difficult to setup, depending on the environment.

If you want an one-liner to see defined variables, try this :

print print_r(array_keys(get_defined_vars()), 1);

If you only want to see a select list of PHP variables, try this which was lifted from the notes at http://php.net/manual/en/function.get-defined-vars.php.

    function getDefinedVars($varList, $excludeList) {
        $temp1 = array_values(array_diff(array_keys($varList), $excludeList));

I have experience with a number of distributed version control systems (DVCS) including Darcs, BitKeeper, Mercuial, Bazaar and now Git.

Git has a lot going for it, so I've decided to "lease" my soul to it for version control.

Git has some quirks, however. One of them is the notion of "push". Git's push doesn't work as I've come to expect in other DVCSes. Here's a good posting on this quirkiness :

Here are some good resources in the area of SSH keys :

## Good overview of SSH keys, including Keychain to remember passphrases

Note PuTTY's Pageant is a Windows form of Keychain

Here are some things I've done to make Git easier to use. There are probably better ways (ex. Git "native" aliases etc.) to do some of these things, but these work for me. This is a work in progress.

Here are some aliases I put in my .bashrc :

alias gb='git branch'
alias gbv='git branch -v'
alias gbva='git branch -va'

alias gci='git citool'

alias gds='git diff --stat'
alias gdsmfh='git diff --stat master FETCH_HEAD'
alias gdtmfh='git difftool master FETCH_HEAD'

alias gl='git log --pretty=short'
alias glf='git log --pretty=fuller'
