    Using RFID at home

    • 4 Comments
    An interesting article about various uses of the RFID technology: http://www.primidi.com/2004/11/20.html and its associated Slashdot link . But, I actually have a different wish from RFID. I always dreamed of some "smart" hand-held RFID scanner that could...

    Another puzzle: Self-extracting EXE

    • 12 Comments
    The rules are the following: 1) Before starting the test, you choose the computer + OS you want, etc. 2) Then, I give you a certain file. 3) You need to create a self-extracting EXE for it, that is always smaller than the original file. You can use any...

    Radio Feedback

    • 5 Comments
    This morning, while listening to some boring songs on C89.5, I was thinking that it would be great to have some sort of an "feedback" mechanism. Something extremely simple and dumb, that every radio should have - two buttons: a red and a green one. If...

    White magic with Microsoft Exchange (Part I)

    • 4 Comments
    Here at Microsoft we have lots of discussion groups, probably in the order of thousands. And I am not sure about how many emails are going daily on these groups but you got the idea. Now, since I always liked to have a peek in everything, I ended up being...

    Script Recipe of the week: Detecting a new disk inserted in the system

    • 0 Comments
    Calvin Hsia presented a method to detect a device arrival in Visual Fox Pro. The code looks pretty long, even for a C++ programmer like me :-) I am wondering if there is a shorter variant... Here is a similar code VBScript, which uses WMI events: ...

    SBS, and a discussion about Shadow-copies and backups

    • 3 Comments
    One interesting things about NTBackup in XP and Windows Server/SBS 2003 is that is has two operating modes: with shadow copy and without shadow copy. First, NTBackup will try to create shadow copies of the involved volumes and try to copy stuff from these...

    Little math problem

    • 14 Comments
    OK, probably you already had your latte this morning but here is nice puzzle: Let's say that a rectangle is "rational" if the ratio between the width and height is a rational number. Now, proof that a rectangle is rational if and only if the rectangle...

    The new MSN Search rocks!

    • 7 Comments
    I was just looking this morning to beta.search.msn.com - the MSN guys did an amazing work. I thought we went to catch up google but now it looks like we are way ahead in terms of usability. But this is just my personal opinion - go ahead and take a look...

    Best Practices for Event Logging...

    • 0 Comments
    I think this is a good topic for a debate. So what is the best way to use the event log? The classical thinking is that a well-designed event log entry should contain only very easy-to-read, easy-to-follow, pertinent observations such as "the disk space...

    WS-Test - a controversial benchmark

    • 1 Comments
    So, it looks like Sun finally published the source code behind the WS-Test benchmark. (Disclaimer: what follows is my own personal position which might not coincide with Microsoft official position) For those not familiar with the controversy around WS...

    A peek into the future

    • 6 Comments
    A simple question: Let's assume that some time from now, we have (near) infinite computing power available everywhere at almost zero cost. How the world will look like?

    Who is scared of Web services?

    • 2 Comments
    I just finished reading a fascinating interview with Henning Kargemann. The initial theme (and title) of the article is related with the now defunct merger proposal between SAP and Microsoft. But, while the merging subject was addressed just briefly,...

    Writing self-replicating code in C#

    • 6 Comments
    No, this post is not about viruses. The problem is to write a C# program that prints to the console an identical copy of its own source code. If you ever went to this exercise in other languages, you already know that the a self-replicating program in...

    Playing with iSCSI

    • 5 Comments
    For a long time I wanted to get my hands on a true iSCSI hardware target. Without a target, the only thing you can do is to learn about iSCSI in a theoretical manner. iSCSI seems to be one of these disrupting technologies. The goal is simple: reinventing...

    Remembering passwords...

    • 5 Comments
    It looks like the number of passwords that I have to remember grows linearly over time. Since I don't have the best mnemotechnic abilities I decided today that it is OK to just forget them. Then, I just tell the whatever-site-I-must-log-on that I've forgot...

    Another way to expose a COM/.NET DLL assembly as a secure DCOM service

    • 6 Comments
    In my last post I mentioned a simple way to expose a .NET class under a secure DCOM connection. That particular method works best if the class that you securely exposed through DCOM lives in your own EXE service (which is written in C# for example). But...

    Script Recipe of the week: Shadow Copy secrets

    • 3 Comments
    One useful feature that you probably noticed in Windows Server 2003 is Shadow Copies for Shared Folders. I will not give too many details about it – suffice to say that it will create periodic versions of your shares. So if you lost or overwritten a file...

    Ponder this

    • 3 Comments
    I just discovered this site . It contains all sorts of math/cs/algorithm-related problems. Some of them are beautiful, others so-and-so... But at least in my case, the effects can be already seen - red eyes :-) Here is an really nice challenge: ...

    The best blog ever.

    • 4 Comments
    Right now (as I write this paragraph), my blog seems to be the best blog ever - it has no posts whatsoever! No rants, perfect silence... it is a perfect blog. The pure white home page gives me such a good feeling. But, by the time you read this, the...
