Since the LvS desktop application (from Learning Via Subtitling project) uses Internet Explorer to embed Microsoft Office Word, Excel, PowerPoint and Adobe Acrobat PDF documents (among others), I added some useful info to the LvS download page on how to work around issues one may face in such a scenario: If you don’t have Microsoft [...]

I recently found a very nice article at CodeProject on Combinatorics algorithms implementation (specifically Permutations, Combinations and Variations with Repetition option) using C# Generics: http://www.codeproject.com/KB/recipes/Combinatorics.aspx It uses a lexicographic algorithm, so it allows one to ask for “next” ...

Just got bitten by the following: Dim takeN As Integer = If(Integer.TryParse(EdTake.Text, takeN), takeN, itemsCount) I had used that instead of writing in 2 lines: Dim takeN As Integer If not Integer.TryParse(EdTake.Text, takeN) then takeN = itemsCount However, there’s an important difference: “If” is a function, so its arguments are evaluated at ...

The other day I submitted my 1st Windows Phone 7 application via http://create.msdn.com Having registered for free as a student developer (being a PhD student on Robotics) via http://dreamspark.com I could only try my 1st app on WP7 emulator – when it gets accepted I will be able to have my WP7 phone unlocked to [...]

Ένας από τους λόγους που διστάζω να συστήσω το Hotmail σε άπειρους χρήστες ή σε παιδιά είναι οι απαράδεκτες παραπλανητικές διαφημίσεις τρίτων που φιλοξενεί. Στην παρακάτω εικόνα βλέπουμε πως ενώ λέει “Είσαι ο σημερινός ΝΙΚΗΤΗΣ ενός iPad 2!”, αναφέρει αμέσως παρακάτω “…για να προσπαθήσετε να κερδίσετε” (δηλαδή ψευδώς σου λέει πως είσαι νικητής στην ...

Just noticed a nice little touch by Microsoft at Zune player when running on Windows 7. When you move the mouse cursor over the running Zune application button on the taskbar you see a mini-player in the preview window that pops up. It even has a “heart” button there to rate the current song as [...]

Windows 7 has kept the taskbar tray from previous versions of Windows, but is providing a different means of managing which icons always show up and when (e.g. can set a specific icon to show up only if they have notifications, or even to never show up on the tray). When you press the “up” [...]

You probably know already that on Windows 7 you can right click icons for executing tasks (applications) on the taskbar and select to Pin them there. You must have also noticed that Windows 7 aware applications show common tasks there, while Windows also shows recent files opened by some application even at cases where the [...]

Τραγική η αυτόματη μετάφραση στα Ελληνικά πολλές φορές. Το Google Toolbar στην παραπάνω εικόνα έχει μεταφράσει το AD (Active Directory) σε μ.Χ. (Μετά Χριστόν) για τα χρήσιμα (για πληροφορικάριους μόνο φυσικά) εργαλεία AD Explorer και AD Insight της SysInternals (που είναι εδώ και κάμποσο καιρό πλέον μέρος της Microsoft).

A very useful action in Microsoft Word is that of text sorting. You select some rows of text and then use the icon “AZ” on the “Home" tab of Word’s ribbon UI. At the dialog that appears you usually would want to “Sort by: Paragraphs”, select “Type: Text” and choose whether you want to sort [...]

The “Change Case” action (portrayed by an “Aa” icon) is a useful one that is usually not noticed by Microsoft Word 2010 users (although often sought for and not spotted by many – probably because somebody misnamed the respective ribbon tab as “Home” instead of “Edit”). It provides several options, the most useful being “UPPERCASE” [...]

I’m sharing here an answer I just gave at: http://stackoverflow.com/questions/3100251/can-i-run-matlab-on-windows-with-ui-just-that-the-code-runs-on-remote-server/7507515#7507515 for archiving, since this may interest fellow Roboticists Launching MATLAB on a server without the GUI is covered thoroughly at ...

I came across a useful Microsoft Support sample called “How to wait for a shelled application to finish by using Visual Basic 2005 or Visual Basic .NET” at http://support.microsoft.com/kb/305368 However, note that there are several gotchas with the code supplied there (just informed Microsoft on that, hope they take notice). Also the article ...

I recently received a promotional e-mail from an e-shop I mainly use to buy home appliances in Greece that was really funny: at the top offer there was a TV, but although the e-mail had been just sent (judging from its date/time stamp) the image already had a mark “exhausted” on it. Obviously it was [...]

I recently came across a very useful Microsoft tool (FCIV) that can compute and store (as XML) checksums (MD5, SHA1 or both hashes) of folders/files you want and can also be used to later on verify the checksum lists to see if they’ve been tampered with. Would be nice to have a GUI wrapper around [...]

I own a Lenovo IdeaPad S10-3t and I’m pretty satisfied with it (apart from the glossy screen and the bevel border arround the touchscreen that doesn’t allow you to easily touch near the screen edges – and would much prefer a NVidia GPU instead of Intel Graphics Accelerator which doesn’t support WDM1.1 btw [keep on [...]

Με αφορμή τον ορισμό του Γιάννη Μίχα ως νέου προέδρου του ΕΦΕΤ, θυμήθηκα σε σχετική συζήτηση στο Facebook μια πολύ κακή εμπειρία που είχα με τον ΕΦΕΤ: Πρόσφατα έζησα μια τραγελαφική ιστορία μετά από ενημέρωση του ΕΦΕΤ μέσω τους website του για μια προβληματική συσκευασία αποξηραμένων σύκων που είχα βρεί. Κατέληξε να με καλέσουν μάρτυρα [...]

Now who has to be more clever? Me or the Twitter programmers who apart from not being polite have managed to fail in simple character counting? They have added automatic link shortening if your message exceeds 140 chars, but fail to count the resulting chars correctly and allow you to press the Tweet button which [...]

Just came across one more case of trying to over-protect users and in the way losing functionality (maybe originally unforeseen functionality, but which is nevertheless useful to many end-users). At Windows 7, Microsoft doesn’t allow you anymore to press F2 or click on a filename to enter edit more for it when the file resides [...]
