Whilst supporting browsers that have no full-page zoom and keeping the accessibility at a maximum, the use of ems in your style sheet is a must. This is not a difficult thing to do and you can still think in terms of pixels, thanks to great tools like the Em Calculator. A word of warning [...]
As a technical lead and working in a company that has had rapid expansion in the last six months or so, I have had the job of being a mentor to some of the new employees. I don’t think any of them had used jQuery before and so for every person that arrived, I needed [...]
The subject of captcha images has been well covered. There are plenty of available resources for creating those warped letters. I created such a control that is a combination of quite a few different ideas and was quite proud of it until not thirty seconds after demonstrating it, someone asked whether it had a ‘play [...]

During my use of the excellent tcpdf library for creating pdf documents with php, I came across an interesting problem when creating a pdf featuring a grid of data.

As any developer should, I am always trying to improve my techniques for creating them so that they are as efficient and maintainable as possible. Up until recently, my usual technique for callbacks and events would be to include the [...]
I have been using Delicious social bookmarking service ever since Blinklist degraded and finally lost the plot with their new design. When I first started using Delicious, a feature of their interface really leapt out at me and I could not wait to include it into a project. The feature I am talking about is [...]
The majority of my ASP.NET development time is spent on web applications.
