Is there a way to achieve the followin...
I'm used to using TFS, and my company is now switching to SVN for a new project (the main reason is to better incorporate our java & .Net codebase under the same source control). I am given to understand merges in subversion are hard (Jeff mentioned this in his latest podcast). What are the problems with subversion, when compared to ...
When looking at Ext JS, I don't get the feeling that it's meant for the same things as jQuery and Mootools. Whilst jQuery and Mootools help with the general workings of a site, Ext JS seems to be focussed on tables and storing data, plus manipulating it. So, is this observation correct, or is Ext Js fit for the same work as jQuery and ...
I have been given the option to either have a Windows laptop or a Mac laptop to do my Java development on. Before committing to one of these, I thought I would find out if there are any issues or benefits I should know about using a Mac laptop over a windows laptop? One thing I did hear was that the Java JDK releases are not always the ...

I'm working on a project constructing an online collaboration tool. Looking at Wikipedia, I noticed that user-generated itterations of a page can easily be compared to each other; the comparison highlights the differences.

How to create web page for comparing two images, preferably using only (X)HTML and CSS, without JavaScript and DHTML / AJAX? The simplest solution would be to put two images side by side together, either touching or almost touching and centered both, or each centered in its own half of page.

I'm looking to create a base table of images and then compare any new images against that to determine if the new image is an exact (or close) duplicate of the of the base.

Hello. I have the following problem. I have a set of elements that I can sort by a certain algorithm A . The sorting is good, but very expensive. There is also an algorithm B that can approximate the result of A. It is much faster, but the ordering will not be exactly the same. Taking the output of A as a 'golden standard' I need to ...
Hello there, I've found myself evaluating both of these libs. Apart from what the GraphicsMagick comparison says, I see that ImageMagick still got updates and it seems that the two are almost identical. So, what should I use for standard image manipulation using C++? (i.e. image load, filters, display) Thank you! QbProg ...

In one bit of code I'm working on, I need to pull a value from the database and check if it is 0. Originally, I had written this as: if ($myVal == 0) { ...
