Some of my colleagues are often reluctant to use ASP.NET 2.0 profile provider to store profile data for their web applications. The main reason for this is the fact that the default SqlProfileProvider that ships with ASP.NET 2.0 “blobicizes” Profile data using string, XML or binary serialization prior to storing information in SQL Server. This obviously puts a rather large overhead Διαβάστε περισσότερα » Μοιραστείτε τη δημοσίευση: email-it! | Share on Facebook | ForaCamp.gr! | DigMe! | BobIt! | Buzz!...

Introduction The Windows Phone 7 emulator that gets installed when you download and install the developer tools does not have any way to access an accelerometer. Although you can add a reference to Microsoft.Devices.Sensors, you will not get any values during application execution. Since I have a Freescale badge that comes with an accelerometer sensor (among others) that works with Διαβάστε περισσότερα » Μοιραστείτε τη δημοσίευση: email-it! | Share on Facebook | ForaCamp.gr! | DigMe! | BobIt! | Buzz!...

Πολύ ωραίο το άλμπουμ φωτογραφιών του ZDNet με τίτλο “ Windows 95 – 15 χρόνια μετά ”. Το ίδιο το άλμπουμ αλλά και τα σχόλια τύπου “ξεχάσατε να βάλετε screen shot του Blue Screen of Death” με κάνουν να σκέφτομαι… … OK το προϊόν που έκανε τον Bill Gates τον πλουσιότερο άνθρωπο στον κόσμο είχε τα ελαττώματα του αλλά… … όλοι αυτοί που σήμερα θυμούνται μόνο αυτά… … και όχι την ασύλληπτη επιρροή που είχε στον κόσμο της πληροφορικής και στη σχέση της με το ευρύ κοινό παγκοσμίως… … όλοι αυτοί … … θα είχαν σήμερα δουλειά...

Was just burning (with Windows7 included image burner) some backup ISO images of Windows Vista x64 final (MVPs who had submitted bugs on Microsoft Connect during Vista beta test cycle were getting both x86 and x64 final Ultimate versions for free). After reinserting the disk I noticed it was trying to run sperr32.exe instead of setup.exe .

Ενδιαφέρουσα η είδηση δια στόματος Scott Guthrie για την (preview beta) έκδοση του WebMatrix , ενός νέου εργαλείου κατασκευής web projects. Το WebMatrix συνδυάζει τις τεχνολογίες IIS Express , SQL Server Compact Edition και ASP.NET Razor με σκοπό την “αυτοματοποιημένη” δημιουργία web projects-κονσέρβες. Οι δυνατότητες του δεν φτάνουν αυτές του Visual Studio το οποίο συνεχίζει να θεωρείται το εργαλείο του επαγγελματία web developer. Φαίνεται όμως πως είναι ο,τι πρέπει για όσους απλά θέλουν να “ξεράσουν” τυποποιημένα...

I will start this blog with an embrace to the genius architecture of DevExpress Xaf framework. As the time passes by and you get more experienced in using it you will soon realize that it has teach you to write so declarative code that almost 95% of it is reusable and should go to your base libraries or else to eXpand !! So the new addition to eXpand has to do with custom pivot sorting . Say that for a domain model similar to you have design an analysis object using your win UI like as you can see Xaf by default...

When we debug our applications we need to have as much information as possible at our disposal. There are a lot of techniques and ways to achieve that. One way to get lots of debugging information is to use Tracing. We can enable Tracing at the Page Level and Application Level. We can view the viewstate information and the events chain when a page is executing, among other things.

(See here more info about it here) Now when you hit enter or double click an entry in that list the standalone editor will open up and will...

Πρόσφατα χρειάστηκε να χρησιμοποιήσω μια memoization συνάρτηση για ένα πρόβλημα δυναμικού προγραμματισμού. Υλοποιώντας την κλασσική τεχνική χρειαζόμαστε μια συνάρτηση σαν την παρακάτω: let memoize f = let cache = new Dictionary<_, _>() (fun x -> match cache.TryGetValue(x) with | true , y -> y | _ -> let v = f(x) cache.Add(x, v) v) Το πρόβλημα με την παραπάνω συνάρτηση είναι ότι χρειαζόμαστε "κριμένα" side effects. Μετά από μελέτη κατέληξα ότι η pure functional λύση θα περιελάμβανε τον Y combinator...

I was just installing the fine IDE NetBeans 6.9 and its installer asked me to install the Java JDK first. It was saying "Java SE Development Kit (JDK) was not found on this computer" (see screenshot). The dialog points one to download the JDK at http://java.sun.com/javase/downloads .

Εν αρχή ο Θεός γέμισε τη γη με μπρόκολο, κουνουπίδι και σπανάκι, πράσινα, κίτρινα και κόκκινα λαχανικά όλων των ειδών, ώστε ο άνδρας και η γυναίκα να ζήσουν υγιεινά και παντοτινά. Ο σατανάς όμως δημιούργησε τα Haagen Dazs... και τα διάφορα cookies. Και ρώτησε: «Λίγη ακόμη σάλτσα βύσσινου;» και ο άνδρας απήντησε: «Ευχαρίστως!» και η γυναίκα πρόσθεσε: «Παρακαλώ για μένα άλλη μια ζεστή Διαβάστε περισσότερα » Μοιραστείτε τη δημοσίευση: email-it! | Share on Facebook | ForaCamp.gr! | DigMe! | BobIt! | Buzz!...

If you go to Tools / Add-ons menu (might be calling them "Plugins" or "Extensions", don't remember the exact English text there) at Mozilla FireFox, do you see one called "Firefox security" there with subtitle "Internal security options editor."?
