  • Big O, how do you calculate/approximate it?

    - by Sven
    Most people with a degree in CS will certainly know what Big O stands for. It helps us to measure how (in)efficient an algorithm really is and if you know in what category the problem you are trying to solve lays in you can figure out if it is still possible to squeeze out that little extra performance.* But I'm curious, how do you calculate or approximate the complexity of your algorithms? *: but as they say, don't overdo it, premature optimization is the root of all evil, and optimization without a justified cause should deserve that name as well.

  • Gtk+ Tables for Layout - Good or Bad?

    - by wag2639
    Hi, I'm just starting to play around with GTK+ and I wanted to stop bad habits before they happen. I see that GTK+ seems to be a little based in HTML/CSS and I was wondering if there are any reasons to avoid using tables for layout.

  • RC2 key schedule

    - by calccrypto
    Can someone explain how the RC2 key schedule works (particularly the very beginning of it)? i know it uses little endian, but my implementation is not working for any key except "0000 0000 0000 0000" Test Vector Key = 88bc a90e 9087 5a Plaintext = 0000 0000 0000 0000 Ciphertext = 6ccf 4308 974c 267f im assuming that the first thing to do with the key would be to change it into bc88 0ea9 8790 5a and yes i know RC2 is not even used anymore, but i would still like to know

  • Why should I Use ASP.NET Membership security model?

    - by ListenToRick
    I'm updating my website at the moment and figure that if I am to update my login/security mode, now is a good time. I have looked through the Membership model which is included in ASP.NET but I'm convinced that it will provide any benefit apart from being familiar to other .NET deevlopers. There seems to be quite a lot of documentation for it, but little discussion for why its worth the effort. Can anybody shed some light upon this?

  • Php/Mysql Simple survey

    - by creativz
    I want to make a little php poll. The script should ask the users a question they can only answer by numbers from 0-999. After pressing the submit button the data should be stored into mysql.

  • What do I use if a CSS framework or grid is bad?

    - by johnny
    Reference this question: http://stackoverflow.com/questions/203069/what-is-the-best-css-framework-and-are-they-worth-the-effort Do I go back to the "old" way of manually creating a template or downloading free ones again. For a little bit I thought a grid was the new thing and the best, now it appears I am wrong after all and not sure of best practice. And, yes, I can write my own CSS but didn't want to create the infrastructure if I didn't have to.

  • Is SparkViewEngine dying?

    - by Stephane
    Hey, I am building a email service based on templates. I thought of using the spark view engine but it seems that It doesn't get much updates anymore. Support on .NET4.0 is not even yet complete and it fails at runtime when used in a console app. The little Intellisense support that was there in VS2008 doesn't seem to work on VS2010 (from the information I have found) Should I avoid it? What do you think?

  • Usage of Maven (and open source in general) in high governance and risk-averse large organizations (

    - by bart
    Does anyone have any good stories of these kinds of organizations being open to using open source (such as tools like Maven etc). Many staff I've encountered have little or no exposure to open source/systems and open source is treated with great suspicion. Some reasons given for this are lack of support and robustness, which is ironic given the number of end-of-life unsupported vendor products that are in production. Bonus points for any success stories where you've seen open source go into orgs like this and have a real benefit!

  • Get JS file via HTTPS from a HTTP page

    - by Mike
    Okay, so what are the ramifications of getting a JS file via an HTTPS call while on a HTTP page. I assume it would just be a little bit of extra overhead. Would there be any warnings about this call from any certain browser? Don't ask why. It's just hypothetical.

  • iPhone SDK reload UIView's content

    - by Matt S.
    I have two views, one view takes the whole screen, the second view covers only a little portion. What I want is for that second view to be on the first view (which I already have done), but the problem is, when I set values (in this case UILabel's) the label on the screen doesn't display that new value. I know for a fact the method gets called, but for some reason it won't change the label's value.

  • How to calculate the average rgb color values of a bitmap

    - by Matthias
    In my C# (3.5) application I need to get the average color values for the red, green and blue channels of a bitmap. Preferably without using an external library. Can this be done? If so, how? Thanks in advance. Trying to make things a little more precise: Each pixel in the bitmap has a certain RGB color value. I'd like to get the average RGB values for all pixels in the image.

  • Choosing the right template engine

    - by asrijaal
    Hi there, since today - I always used simple JSP Tags and JSTL which works but now I'm looking for a little bit more features and maybe more usability. With googling I've found Freemaker, Velocity and Tiles which seem to be very famous. Does someone of you has some further experiences with some of these and can give me a short brief about it. Or are there other frameworks which are worth to look into?

  • Android: DOM-Model to XML

    - by poeschlorn
    Hey Guys, analogue to this one (http://stackoverflow.com/questions/2788345/replacing-xml-in-file-from-document-in-java or http://www.exampledepot.com/egs/javax.xml.transform/WriteDom.html) I try to use it under Android... The problem is, that I can't use the suggested solution under android, because it throws java.lang.verifyError... After reading a little bit, I found out, that the class that was used to store the data to file, is not usable in android... can you suggest another solution, which is similar easy to use?

  • Hidden features of Qt.

    A little is hidden in Qt given splendid documentation. But given vastness of Qt functionality paradoxically many useful features have been overlooked by me (and reimplemented or work-arounded). What Qt functions you wish you have noticed earlier?

  • Fabfile with support for sqlalchemy-migrate deployments?

    - by Chris Reid
    I have database migrations (with sqlalchemy-migrate) working well in my dev environment. However, I'm a little stumped about how to integrate this into my deployment process. I'm using fabric for deployment but having some trouble scripting the migrations part. The path to the to migrations directory in site-packages is dynamic (due to changing egg version number) and I'd rather not hard code my db password into the fabfile. Does anyone have a fabfile that plays nicely with sqlalchemy-migrate?
