    Choosing hosting for Wordpress

      One of the most important questions in launching a website is the hosting. When moving to private hosting, I realized that I don’t need all features of the premium hosting plans, just a reliable hosting with basic tools to help me do my tasks easier, without too much investment. Also I wanted to continue using Wordpress and reuse the content already created in my old website. The requirements of W...

    One of the most tedious bugs in Subversion, ever, is this one. If you want to commit changes to your working copy, and the response of svn is :   svn: The version resource does not correspond to the resource within the transaction. Either the requested version resource is out of date (needs to be updated), or the requested version resource is newer than the transaction root (restart the commit). If you...

  • Brainstorming 2

    In a previous post I explained the facts that forced us to re-think our project idea. Basically, our cool idea of an iPhone tied to a skateboard to create a exertion game require too much programming time. So we searched another idea who is required to be simpler and easy to be implemented in the remaining time.So we got us a round table (the ones in BIT cafeteria are the best!) and put our minds to work.First step...

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...

The parsing goes node by node...

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!

The User Experience that a library provides must be at least equal with is quality and speed. And frankly, CSVtoLINQ rocks on latest two, as I presented in previous articles Import CSV file and query it with LINQ and continuing in LINQ wonder world, but lacks a little on the User Experience(in our case Developer Experience)  by not having some events of starting, progress and ending of the parsing.

Especially important, while parsing huge files, is a confirmation for the user that something happens and (ideally) the point in which the processing is. That is why, thanks to Matt Perdeck for sharing the More >

I am sure that, if you are a developer, at some point in your career heard about and asked yourself: what is LINQ? If not, there’s no problem, you’ll find out now : LINQ comes from language-integrated query and it is a collection of extensions to the .NET Framework that encompass language-integrated query, set, and transform operations. It helps developers by extending both C# and Visual Basic, adding native querying capabilities to these languages. It also comes with class libraries to get the full advantage out of these capabilities.

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 that parsing CSV files is a straightforward and boring task, given that it is quite a while since CSV is around. Some of them are correct – in More >
