  • Reimplementing data structures in the real world

    - by Jason
    The topic of algorithms class today was reimplementing data structures, specifically ArrayList in Java. The fact that you can customize a structure for in various ways definitely got me interested, particularly with variations of add() & iterator.remove() methods. But is reimplementing and customizing a data structure something that is of more interest to the academics vs the real-world programmers? Has anyone reimplemented their own version of a data structure in a commercial application/program, and why did you pick that route over your particular language's implementation?

  • Why is changing displays slow?

    - by Josh Bronson
    I've had many laptops over the course of many years, and while many things have sped up, one thing remains as slow today as it was years ago: (dis)connecting an external display. What's taking it so long to detect the new display and update the pixel buffers? I use Macs primarily, but I think this is equally slow on other platforms.

  • Timestamp problem showing 1970 instead of 1988

    - by gmuhammad
    Hi, I am trying to set default value in DateField using the following statement DateField dateField = new DateField("Birthday:", 567993600, DateField.DATE | DateField.FIELD_LEFT); but when I run my application it shows me 7 Jan 1970 instead of 1 Jan 1988. I checked the time stamp on http://www.onlineconversion.com/unix_time.htm and it shows me correct expected date which is, "Fri, 01 Jan 1988 00:00:00 GMT" I am using 8900 simulator and my date time is correct showing today's date 31 Dec 2010 in date time under options folder. Regards, -gmuhammad

  • Is there an encrypted version control system?

    - by Mike
    I am looking for an encrypted version control system . Basically I would like to -have all files encrypted locally before sending to the server. the server should never receive any file or data unencrypted. -Every other feature should work pretty much the same way as SVN or CVS does today. Can anyone recommend something like this? I did a lot of searches but I cant find anything.

  • Facebook charset detection mechanism?

    - by Void
    Today, I have looked into HTML code of facebook.com, and found something like this: <input type="hidden" value="€,´,€,´,?,?,?" name="charset_test"/> It's repeated two times inside the <form>...</form>. Any idea what this code might be useful for - some kind of server-side client charset detection? As far as I know, browser charset is being transmitted in HTTP request anyway (an "Accept-Charset" header).

  • Must I Install a Gem to Unpack It?

    - by yar
    I wrote up some instructions for freezing a non-native gem in a Rails app today: install the gem sudo gem install fastercsv put the reference in the environment.rb (I think this is only necessary to do unpack with no GEM specified) config.gem "fastercsv" unpack the gem rake gems:unpack GEM=fastercsv uninstall the gem sudo gem uninstall fastercsv I know this must be the long way around: how can I unpack the gem without installing it first? Also: What's the difference between rake gems:unpack GEM=fastercsv and gem unpack fastercsv?

  • When does post-update get called (GIT)

    - by Michael
    My git setup was working beautifully, then stopped cooperating today. Right now, I can git-pull, git commit just fine from my local machine. When I git push, the push goes through, but the server files don't actually get updated. Now I wonder, is my post-update file even getting called anymore? I've checked the permissions, and they are all group +x, and I'm a part of the group... any other suggestions?

  • How to clone repository to a remote server/repository with Mercurial

    - by Alex N.
    Found myself quite confused today about this. I create a blank repository locally(hg init), cloned it to working copy, added some code, commited and pushed it(to local repo obviously). Now I need to share that repository with others. There is a server that has mercurial on it, how do I clone my repository to a remote one such that other developers can access it and pull/push code from/to it?

  • What's the workflow of Continuous Integration With Hudson?

    - by Satoru.Logic
    Hi, all. I am referred to Hudson today. I have heard about continuous integration before, but I have no idea what the heck is a ci-server. Hudson is really easy to install in Ubuntu and in several minutes I managed to set up an instance of it. But I don't quite understand the workflow of a ci-server, or how am I supposed to use it? Please tell me if you have experience about ci, thanks in advance.
