The parsing goes node by node...

Create a simple HTML .MOV player
As a Ruby developer, I work quite a lot with their “special” plugins called gems. The nice fact about the gems is that they bring lots of functionality. By example, there’s a gem for paginating a collection who takes just few parameters and not only that finds out how many objects the collection has, but also how to split them, generating the corresponding links and serving to the original container (that used to ...

UIImageView setImage problem
While working for this semester’s CSCW lab project, I encountered a strange situation: no matter what I did, the UIImageView didn’t load the image. After some digging on the Internet about this, I found out that first thing to look for is whether you're sending the setImage message to the UIImageView instance you expect. Being newbie in XCode and Apple’s technologies in general, I forgot to use...

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...

Objective-C: Putting markers on Map control
This article comes as a completion to my previous ones, XCode : using MapKit with no geocoding available out of the box and XCode: Modal windows – Google maps and shows how to add pins on your already created Map View. First of all, adding the points to the map is not as intuitive as it might seem, so let’s start by creating a new class called POI – point of interest. Its header must be filled...

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...

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...

How to add a nice jQuery slider
This weekend fun was adding to my website the cool sliding control from Jérémie Tisseau website. That pretty it was, I immediately started thinking it as a container to my BNR exchange rate page. The coded worked perfectly, with few modifications. Firstly, Wordpress uses the $ operator for Prototype library, so if you want to add your jQuery library the invocation to Wordpress Firebug will report the error “...

LINQ wonder world
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 que...

Novensys Corporation

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...

How to generate image_src for Facebook links in Wordpress theme
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 m...

Wordpress – Database backup and restore
From time to time, you’ll need to get a backup of your MySQL database and install it on a different machine – as I needed when reinstalling my Windows 7. I wanted to do something simple, as the last time. But now the database sql file is 11 Mb as opposed to merely 2 MB last time. But I thought that this would be a breeze for the MySQL interface that I use and enjoy – HeidiSQL. It’s free, easy to use and user frie...
