  • Ruby: if statement using regexp and boolean operator [migrated]

    - by bev
    I'm learning Ruby and have failed to make a compound 'if' statement work. Here's my code (hopefully self explanatory) commentline = Regexp.new('^;;') blankline = Regexp.new('^(\s*)$') if (line !~ commentline || line !~ blankline) puts line end the variable 'line' is gotten from reading the following file: ;; alias filename backupDir Prog_i Prog_i.rb ./store Prog_ii Prog_ii.rb ./store This fails and I'm not sure why. Basically I want the comment lines and blank lines to be ignored during the processing of the lines in the file. Thanks for your help.

  • How can you write tests for Selenium (or similar) which don't fail because of minor or cosmetic changes?

    - by Sam
    I've been spending the last week or so learning selenium and building a series of web tests for a website we're about to launch. it's been great to learn, and I've picked up some xpath and css location techniques. the problem for me though, is seeing little changes break the tests - any change to a div, an id, or some autoid number that helps identify widgets breaks any number of tests - it just seems to be very brittle. so have you written selenium (or other similar) tests, and how do you deal with the brittle nature of the tests (or how do you stop them being brittle), and what sort of tests do you use selenium for?

  • Master Typing Productivity when Programming/SysAdmin [closed]

    - by Hartator
    I try to learn how to type fast and have managed to learn a lot. I am quite good at typing english text now. I do a lot of programmation though and if QWERTY seems fitted for english text, it doesn't seem fitted to type Ruby, Python, Javascript, Command Line or C++... I have read plenty of articles and if I respect their guidelines/tips, I am using a lot my right pinky specially to type []{}|\;:'"/?=+ enter delete. As you can see this symbols are the ones which are the most used when you are programming and we are using only one weak finger to reach them. Am I learning wrong? Is there is a way to be more productive? (I don't really want to switch to DVORAK) Have you some experiences/tips to share regarding this issue? Original Post : http://stackoverflow.com/questions/12230373/programmer-typing-productivty

  • How do you deal with transitions in animating walking?

    - by Aerovistae
    I'm pretty new to this whole animating models thing. Just learning the ropes. I got a nice walking animation going, which I can loop while a character is walking, but what about when they stop walking? I mean, they could be at any point in the animation at the time the player stops walking. How do I get them to smoothly return to a standing still position without having them snap into that position? The same goes for starting walking from a standing still position. Do you need a separate animation? How is this dealt with?

  • What is the best certification for the self-taught ASP.Net programmer? [closed]

    - by Wahid Bitar
    I learned the C#.Net language from books and many other resources then i did some good projects with ASP.Net "Web Forms & MVC". But i wanna a good certificate to get a better work out of my country as i suppose. I've two choices: Apply for a " college / institute " and start study academic courses to be more professional and maybe in two years I'll "hopefully" graduate with this college certificate. Apply for kind of " Certifications by Companies " like MCTS from Microsoft or something like that and study their straightforward courses then maybe with three or four months I'll get this "Not official Certificate". Is the second type of certifications good for learning and work or the best is the hard way ?. Please give me advises with certifications names please. ======================= Update: This is not related to certain country or region. I'm asking about a good certification and courses for an ASP.Net and C# in general programmer.

  • What kind of performance issues does multiple instances of the exact same object have on a game?

    - by lggmonclar
    I'm fairly new to programming, and I've pretty much learned all the things I know on the go, while working on projects. The problem is that there some things that I just don't know where to begin searching. My question is about performance, and how can multiple instances of the same object affect it -- Specifically, I'm talking about XNA's "GraphicsDevice" class. I have it instanced on four different parts of my game, and in three of those, the object has the exact same values for all the attributes. So, in that case, should I be using the same instance of GraphicsDevice, passing it as a parameter, even if I use it in different classes? I apologize if the question seems redundant, but like I said, I've taught myself most of what I know, so there are quite a few "holes" in my learning process.

  • Apress "Introducing Visual C# 2010" - ISBN 978-1-4302-3171-4 - Conclusion

    - by TATWORTH
    After having spent several weeks reading this book (1230 pages before the index!), I can thoroughly recommend this book as a practical introduction to Visual C# 2010 both to people learning C# and to experianced C# users. It introduces C# through practical examples then gives a good introduction to the Dot Net framework. After dealing with Data Access, it gives a brief introduction to variousUI technologies. The final section deals with advanced topics including a thoroughly practical intruction to windows services. There are copious coding examples and useful tips. Many chapters begin with a quick problem solver solution reference. In short "Introducing Visual C# 2010" in the words of the sub title, is an excellent start to your C# journey with an expert by your side leading by example.

  • How to reduce the number of points in (x,y) data

    - by Gowtham
    I have a set of data points: (x1, y1) (x2, y2) (x3, y3) ... (xn, yn) The number of sample points can be thousands. I want to represent the same curve as accurately as possible with minimal (lets suppose 30) set of points. I want to capture as many inflection points as possible. However, I have a hard limit on the number of allowed points to represent the data. What is the best algorithm to achieve the same? Is there any free software library that can help? PS: I have tried to implement relative slope difference based point elimination, but this does not always result in the best possible data representation. Thanks for your time. -Gowtham

  • Will C++ remain viable for game engines in somewhat distant future?

    - by samual
    C++11 has opened ways, which were only dreamt by the C++ programmers. It has been three years since I have been learning C++, and I am going well. Now I want to get into vedio games. Every core of the game code I saw, was monstourously writtern in C++. My question is - If I get into serious game engine dev, and perfecting it would take, maybe say 10 years, would we still be writing game engines in C++ ?(newer standard) Or, will John Carmack, write id tech 7 in c++? note - I am strictly talking about game engines.

  • How to obtain multiple lines in a single density plot, with a corrected scale?

    - by user1677055
    I have recently started working with microarray datasets and am trying to get my hands on R. I wish to make some plots out of my result data, but however I am stuck at the following. I have the following data (myData), cpg samp1 samp2 samp3 cpg1 0.43 0.32 0.21 cpg2 0.43 0.22 1.00 cpg3 0.11 0.99 0.78 cpg4 0.65 0.32 0.12 cpg5 0.11 0.43 0.89 And I wish to obtain a density plot for this, I did the following, plot (density(MyData$samp1), col="red") lines (density(MyData$samp2), col="green") lines (density(MyData$samp3), col="blue") But doing this does not give me correct plots, because not all sample curves fit within the plot limits. I did try looking for answers, but honestly i am still not able to work this out. Can you help me know how do i set my scale for the above? Or what additional should I do to the above code, so that all the curves are in range?? I have got many samples, so i need a something that could also automatically assign a different colour curve for each of my sample, after scaling it right. Thanks in advance..

  • Should I understand SVN before I jump to GIT?

    - by John Isaacks
    I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

  • Javascript/jQuery: remove shape/path from canvas

    - by bobsoap
    I can't seem to find the function to remove a shape or path from the canvas after it has been created. So I'm creating a bezier curve between 2 points with beginPath(); bezierCurveTo(); stroke(); closePath(); . How can I remove this from the canvas once it's been created? I need to be able to call the remove function via toggle() and blur(). I'm sure something exists for this... Thanks in advance for any help!

  • A question on choosing the next programming language between C/C++ and other languages

    - by SidCool
    I am a java developer (web app and standalone applications) who knows JavaScript, HTML, CSS and has mostly worked on Web applications. I have no knowledge of C/C++ or any other lower level languages. I feel like I should strengthen my CS basics by learning a fundamental language. Should it be C or C++? I am also inclined to learn Objective-C. Does it need basics of C or C++? Or should I go for new languages like Python, Google's Go etc. I know this is a cliche question asked very frequently, but I can use some help here.

  • Should Scala IDE Worksheets be part of your open git repository?

    - by JacobusR
    Those familiar with Scala IDE will know about the great testing environment offered by the Scala Worksheet. You can scribble and scratch, much like in the REPL, but with all the goodness added by the IDE as a whole (refactoring, saving, error checking, etc). When you create a worksheet, it is created with the .sc extension, and also creates a artifact under a hidden directory called .worksheet. This is all fine and dandy, but should one include these in your public .git repositories? People who does not use Scala IDE (or older versions) may find these files confusing. On the other hand, making some of your experiments public to developers who are using Scala IDE, may give them a quick start into experimenting and learning the project.

  • What should someone learn to become a great web-app builder by 2015

    - by rickdronkers
    My brother just started learning some html/css at school and he loves it. He asked me to give my advice on what languages to learn in order to build great web-apps by the time he leaves school. (2015 or something like that.) I did some research, and right now I want to tell him (in this particular order): HTML - HTML5 CSS - CSS3 Javascript - jQuery - AJAX PHP - Zend Framework MySQL Ruby - RoR I would like to know if this is correct before I waste his time. Stackoverflow seems like a place where people know the answer to these kind of questions ;). Thanks!

  • What resources about business should an internal IT department programmer be familiar with

    - by Badger
    I am developer / analyst in an internal IT department at a medium sized business. I have to deal with business people all the time and many of the things I create can have profound impacts on the business. I am starting to regret not taking any business classes in college because I don't understand the first thing about running a business so I don't always understand what people are wanting, the best I can do is "think through it". Does anyone have suggested methods of learning this stuff, maybe some resources. And please don't just say to ask people who work here. I have tried that before and I get no where.

  • Is Carnegie Mellon (CMU) a Javaschool? Are any prominent universities in the US javaschools? [on hold]

    - by user106149
    I'm guessing CMU would teach C and other unmanaged languages (their course listing shows Principles of Functional Programming as a required course for a BSCS), but it's hard to tell from course listings. I'm looking into applying there, where I have an OK chance of getting in , as well as some other mid-to high tier CS schools. I'm wondering how you can tell if a school mainly teaches Java or goes into C/C++. Everyone says (and I agree, from my current programming knowledge) that learning Java in college exclusively is a bad idea, so I'm hoping to avoid ending up at a 'Javaschool.'

  • How to create a simple side scroller game

    - by D34thSt4lker
    I'm still pretty new to game programming and any tutorial that I have worked with stuck to only games with the initial screen. I want to start creating my own games but there are a few things that I still need to learn. One of them is how to create a game that side-scrolls. For example; Mario... Or ANY type of game like that... Can anyone give me a small example to create something like that. I'm not asking for any specific language because currently in school I am learning javascript but I know some c++/java/processing/objective-c as well. So any of those languages would be fine and I could probably implement it in any of the others... I have been searching for some help with this for a while now but could never actually get any help on it. Thanks in advance!

  • Do I need a Point and a Vector object? Or just using a Vector object to represent a Point is ok?

    - by JCM
    Structuring the components of an engine that I am developing along with a friend (learning purposes), I came to this doubt. Initially we had a Point constructor, like the following: var Point = function( x, y ) { this.x = x; this.y = y; }; But them we started to add some Vector math to it, and them decided to rename it to Vector2d. But now, some methods are a bit confusing (at least in my opinion), such as the following, which is used to make a line: //before the renaming of Point to Vector2, the parameters were startingPoint and endingPoint Geometry.Line = function( startingVector, endingVector ) { //... }; I should make a specific constructor for the Point object, or there are no problems in defining a point as a vector? I know a vector have magnitude and direction, but I see so many people using a vector to just represent the position of an object.

  • Does it really takes 5-10 years (or more) to be really good in programming?

    - by Ygam
    I don't get it. Why is there such a notion that it takes this long to be really proficient in a single language? I somehow think that this statement meant that it takes such a long time to master your language, and use it in a lot of context (web programming, desktop applications, mobile applications, etc.). Adding to that, sometimes you get stuck on a single language in your job and doing repetitive things and don't have much time to study other languages, thus for a certain amount of time, you don't really do much learning at all, and that adds to the amount of time. What do you think?

  • Cannot access my own web page

    - by enflam3
    I am developing, learning and experimenting with php,html,javascript,flash and so on. Having web hosting and all of the cpanel, phpmyadmin and other utilities. One day, while updating information, connection between my computer and website just went down. I found out that it is only from this computer, where I cannot access anything. I don't know what is the reason I cannot access website, however this is what I have checked so far: Everything else opens normally, having problem only with my page. Cannot access FTP,cpanel or any kind of information related to the domain and hosting ipconfigs detects IP, but shows request timed out (so its not browser related) Turned off Firewall,AV, Rebooted computer Cleared caches,temp,cookies,histry with CCleaner Checked connectivity with both (wired,wireless) networks ISP has dynamic IP that has been changed about 3 times since issue Checked host file I am out of ideas and understanding what could cause this kind of issue, however couple minutes ago, found out that everything works with proxy server (when adding IP and port to the browsers) Can someone point out what should I check or try to get rid of this problem?

  • What is the point to namespaces in branches in git?

    - by dukeofgaming
    So I mainly use Mercurial for my projects and I decided to sit down and learn all Git's shenanigans to discover if I'm in the right side (at least for me). I'm learning that git uses namespaces for branches and I would like to know (in your experience) what is the point of namespaces?. In Mercurial I could just set the convention of naming branches like so: <branch name> //for "origin" branches <username>/<branch name> //for user branches I imagine that there is more to it than just the name (aside from avoiding naming conflicts), but what do I get out of this seemingly more complicated (not necessarily bad) model?

  • UIView animations on a path not linear

    - by chis54
    I have an iOS application that I want to animate a falling leaf (or several). I have my leaf image in an ImageView and I've figured out a simple animation from the documentation: [UIView animateWithDuration:4.0f delay:0 options:UIViewAnimationTransitionFlipFromLeft animations:^(void) { leaf1ImageView.frame = CGRectMake(320, 480, leaf1ImageView.frame.size.width,leaf1ImageView.frame.size.height); } completion:NULL]; This will make the leaf go from its starting position to the bottom right corner in a straight line. How would I animate this to follow a path or curve like a parabola or sinusoid and maybe even rotate the image or view? Would this be done in the animations block? Thanks in advance!
