    Discussions with EyeStar Patient Coordinators

    After setting my “eyes” (kind of strange to say that isn’t it) on a company that does LASIK, I started to use a very nice feature of their website: instant messaging with the Patient coordinators. First I discussed with Mr. Fred, who was more than happy to clarify all my doubts and respond to all my questions. Then I was impressed that they had a Romanian native speaker in their team and I...

    Xcode – String concatenation

    Don’t be fooled that Objective-C is a Object oriented language. For decades operators overloading is something standard in almost all of them. But in Objective-C you don’t have it. Mostly, I believe that comes from the struggle of Apple guys to assure the stability of the system. A lot of errors can come from poorly designed overloads, thus the crashes can appear. Now let’s put some hands on...

    Apple’s Xcode : symbol(s) not found at Line Location Tool:0

    I am a begginer in XCode. My first real application for iPhone requires connection to a webservices. Since I wanted to use RPC XML or Soap, I searched on internet and found few examples (Apple programmers aren’t so into code sharing) to implement my requests. I want to mention that since the app is in the stage of proof of concept, the code is still not structured in classes separating the data and business...

    Import CSV file and query it with LINQ

    Assume that you have an plain text, old Comma Separated Values file filled with your precious export from a legacy system. How can you process it easily now? The first answer that comes to mind is to parse it and load it into a datatable and later process it by using DataTable.Select() method. But this approach has some limitations – like splitting data into several tables and then join them. One would imagine t...

  • Create GUID in Visual Studio 2005

After a quick digging on MSDN site I found this. It is written in Microsoft style – a lot of information, but no solution. It just mentioned something...

  • 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. What really means is that instead of building in-memory tree with the structure of the XML you'll have some events raised when the parser encounters a special token - the most usual ones are tag start, tag end and found comments. The parsing goes node by node...

How to add Syntax Highlight to WordPress

I wrote quite a while ago about How to implement Syntax Highlight in your WordPress blog. It used an forward, yet permanent approach: modify you’re theme’s header.php. But is it enough?

Lately, I wanted to update my blog’s theme to the newest version. But hey! I had a lot of modifications such the one above that kept me from doing a smooth update: BNR Slider, custom images for RSS and Twitter, hints, Syntax Highlight and so on.

The newest solution that I come up with is using a child theme, feature provided by WordPress engine. Basically, you have a theme applied to you blog More >

Sharing your article for free advertisement on Facebook is a fact. While using different Social Networks sharing tools I had a problem when sharing my articles on Facebook: sometimes the image that I intended to use to represent the article wouldn’t show in the list of the images who can be chosen. Why is that?

It bothered me some while I got the some free time to actually look into this, between exams, work and master research. After some wandering on the internet, I found here the correct directions. What I learnt: Always search for the API!

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:
