Learn about common Mac OS X keyboard shortcuts. A keyboard shortcut is a way to invoke a function in Mac OS X by pressing a combination of keys on your keyboard.

It was about one year ago that we switched to Git. Previously, we used Subversion, through the Mac app Versions, which (rightly) holds an Apple Design Award.

Tumblr lets you fully customize the appearance of your blog by editing your theme's HTML code. This is only recommended for users comfortable hand-coding HTML. If you're not, there are hundreds of great themes to choose from in the Theme Garden!
Once you've created a theme you're proud of, submit it to the Theme Garden to share with everyone on Tumblr!

In this post we have 25 CSS snippets and hacks that will solve many of the most frequently used and, at times, frustrating CSS development tasks. Why reinvent the wheel when there are already plenty of time-saving pre-written CSS code snippets?

As well as some classic and timeless CSS hacks you will also find many CSS3 snippets, like box-shadow, border-radius,linear-gradient and many more.

You know those nights when you race towards a deadline, banging out the CSS as fast as you can, there comes a moment when you pause…wondering what keyword would get rid of that z-index on that anchor, then you make the best guess you can, and type:

z-index: none;

Then go on in life, as it “renders” like you wanted it, it works, no big deal.

But it is. Specifying incorrect values might inject behaviour that you did not expect. It is quite possible that the currently incorrect value might be, in the future, used for a valid value which would distort the design you so carefully did (and how often do we revisit a client’s website to update? :).

Code Style answers key questions for Web developers. Which Web fonts are most common? How to use media dependent style sheets? Make more robust, accessible Websites with open standards technology.

Ropes and knots are among the most ancient and useful technologies ever developed by man, predating the wheel, the axe and probably also the use of fire. Today, they are fast on their way to become an obsolete technology.

The sheer number and diversity of knots that was once in use would be bewildering to the modern city-dweller. About 4,000 different knots are described, ranging from the very simple to the extremely complex.

Not so long ago, each profession or trade had adopted the knots best suited to its requirements, and knotting was part of their daily lives. There are some good knotting reference books available online, and all of them are older than most of us.

I like to figure out the fastest way to do things. I hope these shortcuts will help you become the power user that lies within. These keystrokes should work on Mac OS 10.6 Snow Leopard and 10.5 Leopard (many also work on 10.4 Tiger). I add new shortcuts as I find them, so check back!

Please note that Cmd is short for the Command key (otherwise called the Apple key).

I'm trying to amass a list of programming books with opensource licenses, like Creative Commons, GPL, etc. The books can be about a particular programming language or about computers in general.

What are some freely available programming books on the internet?

I’ve been using git for about 18 months now and thought I knew it pretty well. Then we had Scott Chacon from GitHub over to do some training at LVS, a supplier/developer of betting/gaming software (where I’m currently contracting) and I learnt a ton in the first day.

As someone who’s always felt fairly comfortable in Git, I thought sharing some of the nuggets I learnt with the community might help someone to find an answer without needing to do lots of research.

jQuery is fast becoming a must-have skill for front-end developers. The purpose of this book is to provide an overview of the jQuery JavaScript library; when you're done with the book, you should be able to complete basic tasks using jQuery, and have a solid basis from which to continue your learning. This book was designed as material to be used in a classroom setting, but you may find it useful for individual study.
