I've blogged about Balsamiq Mockups in the past . Excellent tool that was really missing from my toolbox for a long time! I fully recommend it. I give Five Stars! But the reason I'm writing this post is not about how useful and engenious it is but its about the latest blog post Peldi Guilizzoni (creator of the software) wrote. The title is " Donating Your Software: A Whole Lot of WIN! ". Interesting way to look at software. Sure, being a member of WWF or Greenpeace or sending some money to Médecins Sans Frontières Διαβάστε περισσότερα »...

Many Visual Basic.net and C# programmers have grown to like the #Region keyword which allows one to define a foldable region of code giving some text for it (name) that will be displayed in the source code editor when the region is folded (collapsed). In case you’re one of them too (like me) and miss it in Visual C++ , you should look up (at the link provided below) the syntax: #pragma Διαβάστε περισσότερα »...

I was just reading a promotional e-mail from Apple on MacBook Pro . Quoting: The Mac can even run Windows—so it's compatible with the PC world.** With one exception: It doesn't get PC viruses. Pure marketing talk hiding the following facts: 1) There are antivirus products for Macs and they do have a use 2) Running Windows on the Mac (either in a VM or using BootCamp to boot directly Διαβάστε περισσότερα »...

Τυχαία βρήκα πριν λίγες μέρες στο συρτάρι μου το ψήφισμα από το συλλαλητήριο της 7-5-1992 για τη Μακεδονία και μιας και δεν το βρίσκω κάπου στο Google, αποφάσισα για ιστορικούς λόγους (για το μελλοντικό μελετητή παλιών κειμένων) να το καταγράψω παρακάτω προσπαθώντας να διατηρήσω όσο γίνεται την αρχική του μορφή (πλην τυχόν συντακτικών/ορθογραφικών λαθών): ΨΗΦΙΣΜΑ Του Συλλαλητηρίου της Διαβάστε περισσότερα »...

There is a software design principle that states “ Favor composition over inheritance ” Inheritance is a cool way to change behavior. But we know that it's brittle, because the subclass can easily make assumptions about the context in which a method it overrides is getting called. There's a tight coupling between the base class and the subclass, because of the implicit context in which the subclass code I plug in will be called. Composition has a nicer property. The coupling is reduced by just having some smaller things you plug into something bigger, and the bigger object just calls the smaller object back. From an API point of view defining that a method can be overridden is a stronger commitment than defining that a method can be called. That Principe my friends Διαβάστε περισσότερα »...

I guess that everyone is already downloading Windows7 and you all probably use Micosoft File Transfer Manager, What most of you haven’t noticed is that there is another link at the MSDN Top Downloads page which is delivered via Akamai. Usin that my download speeds jumped from 50KB/s to 1MB/s when I switched to it. So if you’re in a harry (like me ;-) use that link . Διαβάστε περισσότερα »...

... it would probably be a 1948 Indian Warrior . For those not into motorcycle history, the Indian Motorcycle Company used to be the largest motorcycle manufacturer before WWII with a fanatical following. The company failed to keep up with the times. Outdated tooling, poor development and quality, underpowered engines alienated even the greatest fans while its greatest competitor, Harley Davidson, won the hearts of riders. The Indian Motrocyle Company folded in 1953....

Just come back from my short holidays this year and I am feeling very relaxed. So I though I should continue my Xaf tips series as I encounter them in my every day work. Be carefull of DevExpress.ExpressApp.DC.TypesInfo.FindTypeInfo method I am only going to say that each time you call the above method if the typeInfo that you expect to get back is not redistered on the system, a new one is going to be created and returned to you. so typesInfo.FindTypeInfo(typeof(Person))!=typesInfo.PersistentTypes.Where(info => info.Type==typeof(Person)).SingleOrDefault() and for you to imagine any kind of conflict you like take into account that a new table named Person is going to be created at your db with the following line if (typesInfo.FindTypeInfo(typeof(Person))!=null) Διαβάστε περισσότερα »...

Τα Concepts δυστυχώς δεν θα είναι στο νέο Standard της C++. Για μένα αυτό ήταν το πιο σημαντικό feature... θα έδινε τέλος στα απίστευτα template error messages... και θα έκανε πραγματικότητα το όραμα του Stepanov για pure generic programming. http://lambda-the-ultimate.org/node/3518#comment-50071 Η C++ πριν από 10 χρονια ήταν η αγαπημένη μου γλώσσα... (Είναι η γλώσσα με τα περισσότερα βιβλία στην βιβλιοθήκη μου) Είχα πει ότι θα ξανά-γράψω C++ όταν θα έχω Concepts, δυστυχώς πλέον είναι πολύ μακριά. Νομίζω ότι κόσμος χρειάζεται μια νέα multi-paradigm system-oriented γλώσσα. It was The Golden Age of Grotesque...

There are times when you need a task to execute periodically. There are two ways of achieving this: Use the System.Windows.Threading. DispatcherTimer Use the System.Threading. Timer Say now that you want to implement a class the executes DoSomething() periodically and also informs through a delegate to whoever listens whent the execution is performed. The class for DispatcherTimer is as follows: public class DTimer { private DispatcherTimer timer; public event Action < int > DoSomething; private int _timesCalled Διαβάστε περισσότερα »...

Πόσες φορές μας έχει τύχει να μήν προσέχουμε την γλώσσα του πληκτρολογίου μας και να γράφουμε σέ ένα πεδίο εύρεσης λατινικούς χαρακτήρες και κατόπιν να χρειάζεται να σβήσουμε αυτό που γράψαμε. Πόσο ποιό καλό θα ήταν να αλλάξουμε την γλώσσα του πληκτρολογίου μας και να συνεχίσουμε από εκεί που σταματήσαμε πληκτρολογώντας μέ ελληνικούς χαρακτήρες. Π.Χ. Θέλουμε να ψάξουμε στον πίνακα Products για τα προϊόντα που περιέχουν στην περιγραφή τους την λέξη αδιαβροχο. Θα γράφαμε select * from Products where ProductName like '%αδιαβροχο%' και φυσικά θα μας επέστρεφε τα προϊόντα για τα οποία έτρεξε το select. Τι θα γινόταν όμως αν γράφαμε το εξής select * from Products where ProductName like '%Adiaβροχο%' . Φυσικά και δεν θα μας επέστρεφε τίποτα. Παρακάτω θα σας δώσω μία sql function η οποία κάνει εφικτό το παραπάνω search GO /****** Object: UserDefinedFunction [dbo].[SearchAny] Script Date: 07/29/2009 14:21:12 ******/ IF EXISTS ( SELECT * FROM dbo. sysobjects WHERE id = OBJECT_ID (N '[dbo].[SearchAny]' ) AND xtype in (N...

In my first blogging days, I received a comment for a post saying how wonderful and special the thing I did was. I was thrilled! Then I received 5 more comments with exactly the same sentence and then 5 more and I realized that this was my first encounter with comment spamming. In order to avoid this I present here a way to add a custom made CAPTCHA ( C ompletely A utomated P ublic T uring test to tell C omputers and H umans A part) in Blogengine.Net (1.4.5.0).

First of all thank you very much for your good words in eXpand . I am going to continue releasing modules and the next one will be a big one so please bear with me. But since I am relasing a lot of code and some other developers contact me that they want to contribute also. I think its time to to move on to apply a more continous integration to our build proccess. What I mean by that? the paragraph bellow was takes from martinfowler.com The easiest way for me to explain what CI is and how it works is to show a quick example of how it works with the development of a small feature. Let's assume I have to do something to a piece of software, it doesn't really matter what the task is, for the moment I'll assume it's small and can be done in a few hours.
