  • Algorithms or OO stuff or new technology

    - by Prashant
    I am trying to learn new stuff about jquery, html, asp .net mvc. I see two school of thoughts - Those who use oo concepts a lot and stress on more object oriented approach Those who rely heavily on algorithms and say a particular problem should take o(n) etc. I am not sure where to spend more time ? . Should I spend more time learning OO stuff or learn new stuff like jquery etc or learn travelling sales man algorithm etc ?

  • SVG to Android Shape

    - by Buggieboy
    I have started learning about vector drawing in Android with the Shape class. Since Shape is a Drawable, and Drawables are usually defined as XML, it sounds a lot like the vector drawing commands in SVG. My question is this: Has anybody created an XSLT transformation, or other mechanism, for converting an SVG drawing description into Android Shapes?

  • How do you unit test Scala in Eclipse?

    - by Jørgen Fogh
    I am learning Scala and would like to set up integrated unit testing in Eclipse. As far as I can tell from googling, ScalaTest is the way to go, possibly in combination with JUnit. What are your experiences with unit testing Scala in Eclipse? Should I use the JUnit runner or something else?

    - by Matt
    I'm an Objective-C newbie and am enjoying reading/learning Objective-C in order to do iPhone development but I'm struggling to understand some of the code, especially the code that comes with the UIKit framework. For example, take this line: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSelection:(NSInteger)section { ... I understand the parameters passed in but am struggling to understand the return parameter. Any help appreciated.

  • Good Domain Driven Design samples

    - by jlembke
    I'm learning about DDD and enjoying every minute of it. However, there are some practical issues that are confusing to me that I think seeing some good samples might clear up. So being at peace with those issues, does anyone know of some good working code samples that do a good job of modeling basic DDD concepts? Particularly interested in An illustrative Domain Model Repositories Use of Domain/Application Services Value Objects Aggregate Roots I know I'm probably asking for too much, but anything close will help.

    - by Dan Dumitru
    I'm sorry for asking yet another "best [insert-technology] book". I know a bit of MVC, I want to start a project in MVC 2 and a good book would be really helpful. Usually, after a while, people come to a consensus what are the top 2-3 books for learning a given technology. Have you read any ASP.NET MVC 2 book?

  • Java class in JavaFX-project in Eclipse

    - by LMA
    I recently started learning JavaFX. At the moment I can't build any JavaFX project with Java class in Eclipse. For every input I get error "package does not exist" Path to JRE is set in project's properties. Same class compiles if it is Java-project (not JavaFx). What should I check in project settings or Eclipse prefferences?

  • Using ruby's OptionParser to parse sub-commands

    - by rampion
    I'd like to be able to use ruby's OptionParser to parse sub-commands of the form COMMAND [GLOBAL FLAGS] [SUB-COMMAND [SUB-COMMAND FLAGS]] like: git branch -a gem list foo I know I could switch to a different option parser library (like Trollop), but I'm interested in learning how to do this from within OptionParser, since I'd like to learn the library better. Any tips?

  • What is C# equivalent of PHP's mysql_fetch_array function?

    - by Mike Biff
    I am learning C#/ASP.NET and I am wondering what the C# equivalent of the following PHP code is? I know the userid, and I want to fetch the rows from this table into the array of the variable "row", so I then can use it as "row['name']" and "row['email']. $result = mysql_query("SELECT email, name FROM mytable WHERE id=7"); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { printf("Email: %s Name: %s", $row["email"], $row["name"]); } Thanks.

  • Perl vs Python but with more style than normally

    - by user350571
    I'm learning perl and everytime I search for perl stuff in the internet I get some random page with people saying that perl should die because code written in it looks like a lesson in steganography. Then they say that python is clean and stuff like that. Now, I know that those comparisons are always stupid and made by fellows that feel that languages are a extension of their boring personality so, let me ask instead: can you give me the implementation of a widely known algorithm to deal with a data structure like red-black trees in both languages so I can compare?

  • Git/Mercurial (hg) opinion

    - by Richard
    First, let me say I'm not a professional programmer, but an engineer who had a need for it and had to learn. I was always working alone, so it was just me and my seven splitted personalities ... and we worked okey as a team :) Most of my stuff is done in C/Fortran/Matlab and so far I've been learning git to manage it all. However, although I've had no unsolvable problems with it, I've never been "that" happy with it ... for everything I cannot do, I hae to look up a book. And, for some time now I've been hearning a lot of good stuff about hg. Now, a coleague of mine will have to work with me on a project (I almost feel sorry for him) and he's started learning hg (says he likes it more), and I'm considering the switch myself. We work almost exclusivly on Windows platform (although I manage relatively ok using unix tools and things that come from that part of the world). So, I was wondering, in a described scenario, what problems could I expect with the switch. I heard that hg is rather more user friendly towards windows users, regarding the user interfaces. How does it handle repositories ? Does it create them the same way as git does (just one subdirectory in a working directory) and can I just copy the whole project directory (including git repo) and just carry them somewhere with no extra thinking ? (I really liked that when I was choosing over git/svn). Are there any good books on it that you can recommend (something like Pro Git, only for Hg). What are good ways to implement hg into Visual Studio/GVim for Windows, or into Windows Explorer so I can work relatively easily (I would like to avoid using the command line for everything regarding it, like in git shell). Is there something else I should be aware of (please, on this don't point me to other questions ... they just give me a ton of info, and I'm not sure what is it that I should take as important, and what to disregard). I'm trying to cut some time, since I cannot spend all that time relearning hg, like I did for git. I've also heard git is c project, while mercurial is python ... is there any noticeable difference in speed. git was pretty speedy ... will I encounter some waiting while working. Notice: All my projects are of let's say, middle size ... mostly numerical simulations ... 10-15000 lines (medium size?)

  • Adobe Color Profiles/Color Spaces, how is it possible that this works?

    - by leeand00
    I'm learning about Color Profiles/Color Spaces/Monitor Color Management Profiles and I was just wondering how any of that justified considering the fact that I could throw the entire color anything off by adjusting the brightness and contrast of my monitor? Additionally there are things like lighting in the place where your monitor resides. I don't understand what makes it possible to know that the colors that you are looking at on your monitor are accurate. I really don't have any idea where to start (considering I obviously can't even get the terminology right in the first place...:-p)

  • Should I use Python or Assembly for a super fast copy program

    - by PyNEwbie
    As a maintenance issue I need to routinely (3-5 times per year) copy a repository that is now has over 20 million files and exceeds 1.5 terabytes in total disk space. I am currently using RICHCOPY, but have tried others. RICHCOPY seems the fastest but I do not believe I am getting close to the limits of the capabilities of my XP machine. I am toying around with using what I have read in The Art of Assembly Language to write a program to copy my files. My other thought is to start learning how to multi-thread in Python to do the copies. I am toying around with the idea of doing this in Assembly because it seems interesting, but while my time is not incredibly precious it is precious enough that I am trying to get a sense of whether or not I will see significant enough gains in copy speed. I am assuming that I would but I only started really learning to program 18 months and it is still more or less a hobby. Thus I may be missing some fundamental concept of what happens with interpreted languages. Any observations or experiences would be appreciated. Note, I am not looking for any code. I have already written a basic copy program in Python 2.6 that is no slower than RICHCOPY. I am looking for some observations on which will give me more speed. Right now it takes me over 50 hours to make a copy from a disk to a Drobo and then back from the Drobo to a disk. I have a LogicCube for when I am simply duplicating a disk but sometimes I need to go from a disk to Drobo or the reverse. I am thinking that given that I can sector copy a 3/4 full 2 terabyte drive using the LogicCube in under seven hours I should be able to get close to that using Assembly, but I don't know enough to know if this is valid. (Yes, sometimes ignorance is bliss) The reason I need to speed it up is I have had two or three cycles where something has happened during copy (fifty hours is a long time to expect the world to hold still) that has caused me to have to trash the copy and start over. For example, last week the water main broke under our building and shorted out the power.
