  • LightSwitch spews out HTML5, Google spews out yet another language, Blockly

    @fanbaby: Once the best definition of a language is "à la something", its fate is not very bright. Unless an influential company puts all its weight behind it and keeps it there.

    Google seems to be back at its old game of throwing random stuff around hoping that some will stick, eventually... which may be fine in other fields, but definitely not in programming languages. The canonical 10000 hours are not a figure of speech, and Google doesn't seem to be willing to put that in themselves.

  • Apparently the IPO didn't fund Linkedin enough to hire decent programmers

    I wonder if anyone use "lossy" encryption. This may sound dumb, but, if you simply crap out the original password, like say, when user supply the password, you do some stupid

    1
    foreach(char c in stringValue)    total += (int)c;

    And use "total" as the new password and run it through encryption. So, even if they managed to hack the entire thing. All they get is garbage password, LOLz.

    Obviously my example is bad because "PASS" and "ASSP" can both login, and the encoding is too lossy. But, basically if you can do this with balanced encoding quality, you are able to protect the user password as the encoding is lossy.

    It is not the same as typical file encryption because you don't care about getting perfect binary back. You want to make sure after you decrypt the password 100%, it is still useless.

    That's not dumb at all... what you call "lossy" encryption is just a form of hashing, including the problem with collisions.

    It's always nice to see a mind click. Impressed.

    @Dr Herbie: +1

    True multitasking would be nice, but I appreciate how that could easily turn into a battery hog. I would settle for a global event system able to launch/resume some user-approved applications when a specific event occurs.

    Maybe someone should put in on a blog, so this thread does not pop up everytime someone tries to install Fx Cop

    Yes, a blog post would be brilliant.

    Wouldn't take too long to write: all it actually needs is a link to the FxCop installer Tongue Out

  • The Windows 8 nadir

    Metro is heard for a long time, I just wonder why noone happen to sell LCDs/LEDs with touch built-in. This would be popular for even Win7 users. And from what I saw 5 years ago in ShenZhen the parts are not very expensive (like a few hundred CNY or something less than 80 USD for 15-inch display, and that supports single touch point though), why noone try to do that?

    [...]

    That's because single point touch doesn't work very well (and if it's a resistive touch you are thinking of, then it just plain sucks) unless you apply it to applications that were specifically written around its limitations. Most interesting gestures require multiple fingers and, without that, you don't get a good experience enough to compensate the lack of hovering and a lazy right click.

  • MS working on a same compiler for C++ AND C# ! Not in 'incubation' but for production !

    I'm no expert in this, but I think reference counting is also more predictable (latency wise) making it superior memory management method for real time applications. GC performance depends on the GC algorithm, but I never recall seeing a GC that was conclusively proven to be faster than reference counting. One thing GC does have that reference counting does not is the ability to handle circular references though. 

    The performance of reference counting is pretty much constant with respect to the amount of available memory. Conversely, garbage collectors will improve steadily as you add more memory (interesting special case when the amount of memory is infinite). So, if GC's aren't ahead right now, they will eventually be.

    ... And if a modern C++ app is supposed to use smart pointers, how is that more efficient that C# references?  I thought the lesson learned by the designers of the GC was that reference counting was slower than garbage collecting.

    I believe that needs to be put in the right context. Garbage collection can be more performant than reference counting, so if you are designing a language that relies heavily on managed memory, a GC is the way to go. But there's the rub... C++ offers you options that allow you to express your code without using reference counting at all, possibly at the expense of memory safety.

    Take for instance an object that is not meant to survive the scope it's allocated in. Assuming it's a reference type, in C# it gets invariably allocated on the managed heap and you incur collection costs. In C++, you could use a unique_ptr, or even just allocate it on the stack. Sure, that's not foolproof, but the gains in performance and memory pressure are significant.

    That's where a smarter compiler could really help: in C++ it could be more aggressive in detecting dangerous situations; in C#, it could detect cases in which the lifetime of an object can be safely determined at compile time and get them out of the hair of the GC (and possibly onto the stack).

    This is just the tip of the iceberg, but I already rambled enough. Smiley
