    The various aspects of Open Source

    • 26 Comments
    A funny thing that I just realized is that the term "open source" is generally used to denote several types of software. Without actually defining what "open source" means, I am thinking to several categories: 1) Hobby projects . These are projects started...

    • 3 Comments
    Or at least this is what Bob Metcalfe says in an interview . Given the increasing competition between FC and iSCSI, it is not a surprise from the author of Ethernet to see such headlines. Here is a quote: "Fibre Channel's doomed," he said in a recent...

    • 6 Comments
    Argh... looks like I am rediscovering the wheel. In the past I used services like http://tinyurl.com but it looks that I don't need it for my permalinks. At least on a Community Server powered blog, I can simple write: http://blogs.msdn.com/423926...

    Article: Too much homework can be counterproductive

    • 3 Comments
    You might think that it is almost impossible to "measure" how much homework is needed. Surprisingly, this is not that hard to figure out - a indirect method is to compare various teaching methods in several countries, and then putting them side by side...

    Never use catch(…)

    Yun Jin had an interesting note on the catch(…) operator. There is an additional thing that I would like to mention. On earlier versions of the Microsoft C++ compiler, this language construct was used as a general garbage sink of all exceptions, including...

    How to fix the bogus daylight behavior of DateTime.FromFileTime()

    • 3 Comments
    There is an important difference in the way the DateTime.FromFileTime (...) method adjusts for daylight changes versys the rest of the Win32 world. This thing can be truly confusing if you are not aware about the problem. The cause is pretty subtle, and...

    A weird-looking concept: End-user development?

    • 5 Comments
    Normally, you would think that developers and end users do not mix. And, given the current state of software development, I would agree. But , on the other side I always thought that we need more tools that allow simple end-users to do more or less...

    Is corporate blogging still risky?

    • 2 Comments
    In my personal opinion, probably yes. But right now, I personally think that the risk is pretty moderate. Here are the main reasons: 1) A source of danger in the past was a phenomenon that I will call "rumor rush". The atmosphere around most companies...

    One intriguing observation about the genetic code is that, in the end, it's pure software. In a conceptual sense, the genetic material is just abstract information: sequences of numbers (similar with the machine code). And, while the "software" would...

    How does a four-dimensional world look like?

    • 8 Comments
    Eric Lippert is running an eye-catcher series on High Dimensional spaces (see here part one and two ). Which got me thinking. The classical laws of Optics work can be easily generqalized to N spatial dimensions. You could easily imagine things like refraction...
