  • Objective-C: Use NSXMLParser

    Almost any time you'll need to pull some data from the web. Using Objective-C you have at your disposal a pretty good XML parser - the event-based version.

The parsing goes node by node...

No more constrained to some slides, just him, Visual Studio and the audience. Yes, the aud...

  • Agile – techniques, principles and methodology

    Because the software industry is so different than any other, the development model used prior of creating agile methodology was taken from the engineering disciplines, such as civil or mechanical engineering. Those disciplines put a lot of emphasis on planning before you build because the resources are very expensive and cannot be wasted because of bad synchronization or different physical characteristics like...

    How to add ui-icons to JQuery tabs

      While working in UniBonn, I have a lot of contact with Ruby on Rails and JQuery; I actually started loving its interactivity and stability. But lately I encountered a small situation with the tabs object that they offer. This is their default view, with Redmond theme applied. Nice and clean, you might say. But what’s missing? These tabs don’t support images. So you’ll not be able to show an image to speci...

  • Objective-C: Base64 to NSString and NSString to Base64

    While working on the CSCW Lab project, I encountered a situation in which the XML-RPC call returned an image, of course encoded as Base64.

  • Flash UI changes

    Since last week the Flash application changed- I added support for numerical keys for hitting. We mapped the numerical keys 1 to 6 to the 6 animals positions that can be hit. This way, it is enough to press a key to simulate the throw of a ball. The reason behind this application architectural change is that we needed an smart way to simulate the sensors that were hit, without actually having the entire setup in...

    Adobe Flex 3 has a very interesting component : LocalConnection. The idea behind is that the modules (which runs on client side) might change some data. The exchanged data is not limited at all to simple forms, but can be from a simple String to a XML or Arrays. Few things must be known from the start, but as any technology, only after you learn it everything becomes easy. First of all, the communication can...

Each ASP .Net page has a property called Header who is the “hidden” header...

  • cPanel: using Cron Jobs

    First – what is a cron job? It is a piece of software which can be run at specific times by the cron service. By example, one could set a cron job to update his application exchange rates from a server every day at a specific hour so its application will be up to date. I used it because the Romanian National Bank doesn’t have a proper page to check for exchange rates – they present just the...

Let's consider the following code: var xml:XML = <Workbook...

While working on my idea of presenting on this website also the Romanian National Bank exchange rates (very useful in this crisis time), I end up in choosing a form of visualization.

One might argue that text is good enough, but for me frankly graphs and charts are the best. So I started looking on the internet for free and customizable charting tools.

From the plethora of choices on the web I will present just a few:

Google has been the most improving mailing web interface that I know. Having a whooping 2 GB storage space when launched, he slapped over the face all his competitors, whom at that time had 4- 5 MB of storage space. Now is 7.5 GB and increasing.

The interface is very clean and intuitive, but not lacking the good looking ( example of bad looking is Squirrel Mail who looks obsolete, due to the right angle corners, opposed to the round corners approach in Gmail). Also the code completion for emails, the spell checker and other goodies makes this interface the most interesting in my More >
