Research on LASIK

When starting such an important process as LASIK surgery (on which your sight is affected) it is crucial to get as many information as you can. You might want to bing it, to Google it and also ask your friends about it. Also discuss with professionals! You never know when you will find someone who already had it and can give their own personal impression. I found a lot of information on the Softpedia forum, in an...

Add Silverlight to Wordpress

As I presented earlier, you can easily create a Silverlight video player and you can see it working pretty nice. Not to mention that it can play a lot of formats and it is only 344 kb in size! Now let’s see how this is possible and how can one do it on his website. From the start, Silverlight was meant to be as easiest as possible to develop and deploy. Also, the cross browser (running on all major b...

Bonn dorms

Today I visited Bonn in order to find out how my possible future dorm will look like. This one is placed in Bonn, Pariser Str. 54.

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...

How to add Zend Debugging capabilities to Apache

How to make a Print Screen on Microsoft Source using WPF

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...

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...

Silverlight VideoPlayer for RailsCasts

I am and will be a Microsoft Developer. While working for convenience with other tools, I love strong type languages. I don’t want to ship products because I saved once and hit “s” one more time, so my product will be shipped with that small, human and yet unpardonable error in code. How many times did you loose your time and effort with PHP in order to find a small mistake like this? In my pursue on Microsoft ...

Agile – techniques, principles and methodology

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...

Create GUID in Visual Studio 2005

From time to time you need to create a GUID (Global Unique IDentifier) in order to mark your dlls. Looking in my Visual Studio 2005 I saw that this command wasn’t available in any tools menu, nor in the Customize toolbars one as a shortcut to a command. 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...

GPS – Global positioning system

GPS is the oldest one from the frameworks available to the large audience. It isn't the first positioning system, but it is the one with the most success and longevity. It started as a military project in 1957. Because of the cold war, once the Russians sent to space the first man-made satellite, a team of scientists started monitoring its radio transmissions. The crucial discovery was that, because of the Doppler...

Add SyntaxHighlight to Windows Live Writer in Preview mode

Windows Live Writer (shorter: WLW) is one of the most popular blog authoring tool that I also happen to like and use. And I say this because of its features – I especially enjoy the Preview tab. But what it really lacks is previewing the ENTIRE page - it will get only the html and some css. So no Syntax Highlighting of my code? Let me tell you how I solved this issue. As a blog writer I searched for something that ...

My own LASIK experience

In this series of articles I will present my own experience with LASIK. All started around 4 years ago when I was so disappointed in wearing gasses in winter time. Any time when I went from freezing outside to the warm of a shop, by example, my glasses become full of condensed water. If you have glasses you understand what I mean, if not, think to the car’s wind shield in winter, full of water drops and...

Objective-C: Putting markers on Map control

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...

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...

Flex 3 debugging && Nod32 != Love
