I have found a very interesting site the other days that would compare various MVVM frameworks from codeplex in terms of popularity, documentation and features. I think it's quite interesting so I decided to share it with people. http://www.japf.fr/silverlight/mvvm/index.html P.S. I really like Google bookmarks, I believe it's one of the most useful tools Google has ever given to us!...

Πριν από μερικές μέρες μια συνάδελφος ήρθε με το εξής πρόβλημα, ήθελε να δείξει κάποια δεδομένα σε ένα treeview control σε ένα web page. Στην ουσία ήταν μια ιεραρχία που από την δομή του πίνακα έβγαινε αρκετά εύκολα με ένα order by clause. Όμως δεν ήταν τόσο απλά τα πράγματα, ήθελε να υπάρχει ταξινόμηση ανά επίπεδο ιεραρχίας το οποίο ορίζονταν από ένα άλλο πεδίο. Ολόκληρο το άρθρο εδώ...

If you ever created a professional website/application you’ll probably know the value (you’ve probably learned it the hard way as I did ) of stress testing your web applications. There are plenty of tools you can use in order to stress test your web site, ranging from Microsoft Visual Studio to CMD Line tools. Yesterday I found another one StresStimulus . StresStimulus is an extension for Fiddler (an awesome and free web debugging proxy) which enables us to create instant load tests with virtual users . You can record a browser activity (like creating a user), replay it under concurrent load and get the results for the performance of web pages and the entire test. If you prefer a simple but powerful tool this one is for you....

I remember that long time ago I wrote my own synchronisation class in order to sync folders for the needs of a project I was working on. I'm sure many of you have done something similar. Like me, maybe some of you even enjoyed writing that code. But now Microsoft Sync Framework is here! And the job is sooooo easy! Take a look at the code: var provider1 = new FileSyncProvider(@"C:\Temp\FolderA");
var provider2 = new FileSyncProvider(@"C:\Temp\FolderB");
provider1.DetectChanges();
provider2.DetectChanges(); var agent = new SyncOrchestrator
{ LocalProvider = provider1, RemoteProvider = provider2, Direction = SyncDirectionOrder.DownloadAndUpload
}; agent.Synchronize(); What is Microsoft Sync Framework? From MSDN: A comprehensive synchronization platform that enables collaboration and offline access for applications, services, and devices with support for any data type, any data store, any transfer protocol, and any network topology.

Αργά αλλα σταθερά η F# δείχνει την δύναμη της και εδραιώνεται στις συνειδήσεις των .Net προγραμματιστών. Μετά και την ανακοίνωση του Async support στις vNext (C#, Vb) είναι ξεκάθαρο ότι η F# επηρεάζει και ξεχωρίζει. Στο παρακάτω link όσοι ενδιαφέρονται μπορούν να δουν και το enterprise πρόσωπο της F#. http://msdn.microsoft.com/en-us/fsharp/gg634701...

As I mentioned at that post, the latest official version (ignoring any unofficial / experimental versions that you might find around at some educational research labs’ websites) doesn’t work [...]...

It's sad when great ideas get lost in the name of money and progress It's sad but it was recently announced that one of the most well known tools for .Net development will cease to be offered for free. I am talking of course for .Net Reflector .Unfortunately in the Greek community I haven't seen to much about it which makes me even more sad about the software development in my country (at least there has been a short discussion here ). Anyway, just for the record, the official announcement of the Reflector going for a price model is here . It's a big change indeed but I think we should have seen it coming. We all are part of a community (.Net) which is used to pay for everything, it's almost as we don't enjoy coding otherwise. Starting from our IDE going all the way to the most "sofisticated" tools - which are usually free in other communities (e.g. Java) - like NHibernate Profiler , NCover , Memory Profilers and many many more. It's amazing that most of these tools are quite often WORSE that their open source...

Σας παραθέτω μια προσέγγιση στη λύση του προβλήματος "christmas" του hellenico.gr Ο αλγόριθμος που χρησιμοποίησα είναι του Kruskal. Η Δομή δεδομένων μου για Disjoint Sets είναι Linked List. Για το δεύτερο MST κάνω: Για κάθε edge που ανήκει στο πρώτο MST την αφαιρώ απο τη λύση και ψαναφτιάχνω το linked list χωρις αυτήν. τρέχω τον Kruskal απο το σημείο που είχε σταματήσει ο πρώτος αφαιρόντας το κόστος της συγκεκριμένς ακμής αν το αποτέλεσμα είναι το επόμενο μεγαλύτερο του πρώτου ειναι και το σωστό (Sorry για τα ορθογραφικά.. δεν είχα το χρόνο για να τα τσεκάρω) Οποιοδήποτε σχόλιο και διόρθωση είναι καλοδεχούμενα!!! Κώδικας => http://pastebin.com/4qzCLFu1 . Το Πρόβλημα: Όσον αφορά στην μορφή της εισόδου, στην πρώτη γραμμή θα δίνεται το πλήθος N των κορυφών / διασταυρώσεων και το πλήθος M των ακμών / δρόμων. Σε καθεμία από τις υπόλοιπες M γραμμές θα δίνονται τα χαρακτηριστικά μιας ακμής e: πρώτα δύο θετικοί ακέραιοι που αντιστοιχούν στα δύο άκρα της ακμής, και έπειτα ένας θετικός ακέραιος που αντιστοιχεί...

jCarousel is a well known carousel build using JQuery by Jan Sorgalla . I have port the Carousel with dynamic content loading via JavaScript to .Net and created NCarousel which is basically a classic asp.net server control that a developer can configure using c# . A list editor and added to eXpand (NCarouselListEdior) and all NCarousel control properties are also in the model so you can configure it from there. A special interface IPictureItem should be implemented by your BO object in order editor to work. public interface IPictureItem { string ID { get ; } Image Image { get ; } string ImagePath { get ; } } At least one of Image, ImagePath peoperties should have values To make the design of NCarousel skin design fast without having to go back to the model many times I have added the AllowOverride attribute at model, which basically does not inject any specific to view css, thus allowing the skin to be overridden by adding a ling to a css file in your...

Hi folks! This is an e-mail that I sent today to my team in the IT&T department after a very interesting day and the cummulative experience I get here this 9 months in Tirana, Albania. I thought to share it with you just for the fun of it. " My dear team mates! Please spend 5 minutes of your time to read this through. As you know we are something less than a week from the going-live of NAV. Based on what I’ve experienced so far in my time being here I came up with an idea to “arm” ourselves with something coming from the American army, which is very trendy at all times, even in Hollywood! I decided to base our operations on a DEFCON level! J Let me explain some things about DEFCON and its meaning: DEFCON stands for DEF ense Readiness CON dition, and it has the following levels: (Source: Wikipedia) Normally and depending on the DEFCON level, soldiers (that’s our role) have different weapons to tackle each one. “Our weapons” , you might ask? Not many but are enough most of the times to get through the difficulties:...
