  • When to use an Array vs When to use a Vector, when dealing with GameObjects?

    - by user32465
    I understand that from other answers, Arrays and Vectors are the best choices. Many on SE claim that Linked Lists and Maps are bad for video game programming. I understand that for the most part, I can use Arrays. However, I don't really understand exactly when to use Vectors over Arrays. Why even use Vectors? Wouldn't it be best if I simply always used an Array, that way I know how much memory my game needs? Specifically my game would only ever load a single "Map" area of tiles, such as Map[100][100], so I could very easily have an array of GameObjectContainer GameObjects[100][100], which would reserve an entire map's worth of possible gameobjects, correct? So why use a Vector instead? Memory is quite large on modern hardware.

  • Not able to get siblings value from table row

    - by Sullan
    Hi All, I am trying to get values from adjacent columns, when a radio button is clicked for that row. I'm able to do so, but the problem I'm facing, when there are more elements in the radio button column, then i am getting null values(i.e 2nd row is not working). Please help...Code is all follows <table id="dist_list" class="data"> <tbody> <tr> <td> <input type="radio" value="636406" name="distRG" id="radio_7" /></td> <td class="selected">Company 1</td> <td class="siteId">1234</td> <td class="siteName">First Company Name</td> </tr> <!-- Not able to get values from this row, since there are more elements in it --> <tr> <td> <span class="jqTransformRadioWrapper"><a rel="distRG" class="jqTransformRadio" href="#"></a> <input type="radio" value="636406" name="distRG" id="radio_2" /> </span></td> <td class="selected">Company 2</td> <td class="siteId">2345</td> <td class="siteName">Second Company Name</td> </tr> <tr> <td><input type="radio" value="636406" name="distRG" id="radio_3" /></td> <td class="selected">Company 3</td> <td class="siteId">3456</td> <td class="siteName">Third Company Name</td> </tr> <tr> <td><input type="radio" value="213584" name="distRG" id="radio_4" /></td> <td class="selected">Company 4</td> <td class="siteId">4567</td> <td class="siteName">Fourth Company Name</td> </tr></tbody></table> jQuery script $("input[name=distRG]").click(function() { var owner = $(this).parent().siblings('td.selected').text(); var siteId = $(this).parent().siblings('td.siteId').text(); var siteName = $(this).parent().siblings('td.siteName').text(); alert(owner); alert(siteId); alert(siteName); });

  • Google Dart vs CoffeeScript? Which one should one learn?

    - by garbage collection
    I was thinking about learning CoffeeScript some time in the future. In the mean time, Google came out with Dart that seems to do what CoffeeScript does. Google says: Dart code can be executed in two different ways: either on a native virtual machine or on top of a JavaScript engine by using a compiler that translates Dart code to JavaScript. This means you can write a web application in Dart and have it compiled and run on any modern browser. Does anyone know advantages and disadvantages of learning Dart or CoffeeScript?

  • How to write a jUnit test for this class?

    - by flash
    Hi, I would like to know what's the best approach to test the method "pushEvent()" in the following class with a jUnit test. My problem is, that the private method "callWebsite()" always requires a connection to the network. How can I avoid this requirement or refactor my class that I can test it without a connection to the network? class MyClass { public String pushEvent (Event event) { //do something here String url = constructURL (event); //construct the website url String response = callWebsite (url); return response; } private String callWebsite (String url) { try { URL requestURL = new URL (url); HttpURLConnection connection = null; connection = (HttpURLConnection) requestURL.openConnection (); String responseMessage = responseParser.getResponseMessage (connection); return responseMessage; } catch (MalformedURLException e) { e.printStackTrace (); return e.getMessage (); } catch (IOException e) { e.printStackTrace (); return e.getMessage (); } } }

  • I want to make an item on a Windows 7 Jump List run as administrator

    - by ProfKaos
    Only occasionally I have to open a Visual Studio project with a VS instance running under admin. This is a little inconvenient because I can't use the short-cut for that project in the VS Jump List. How can I modify the Jump List entry to force VS to open that project running as admin? Please note that I'm not trying to avoid providing admin auth to do this. I'm just trying to avoid having to run VS as admin, and then having to open the project from within VS once it opens.

  • How can I require an attribute on a class definition?

    - by spoulson
    Is there a way to enforce a compile requirement for certain attributes on a class or interface implementation? For example, let's say my application uses a series of static classes that contain const int resource values. I'd like to decorate the class in a Description attribute to describe its contents. In concept, I'd like to apply this attribute requirement to an interface, then each static class would implement it with its required Description. I could write a run-time check or a unit test to check compliance. But really a compile-time check would be best. Is there such a thing?

  • Nested attributes form for model which belongs_to few models

    - by ExiRe
    I have few models - User, Teacher and TeacherLeader. class User < ActiveRecord::Base attr_accessible ..., :teacher_attributes has_one :teacher has_one :teacher_leader accepts_nested_attributes_for :teacher_leader end class Teacher < ActiveRecord::Base belongs_to :user has_one :teacher_leader end class TeacherLeader < ActiveRecord::Base belongs_to :user belongs_to :teacher end I would like to fill TeacherLeader via nested attributes. So, i do such things in controller: class TeacherLeadersController < ApplicationController ... def new @user = User.new @teacher_leader = @user.build_teacher_leader @teachers_collection = Teacher.all.collect do |t| [ "#{t.teacher_last_name} #{t.teacher_first_name} #{t.teacher_middle_name}", t.id ] end @choosen_teacher = @teachers_collection.first.last unless @teachers_collection.empty? end end And also have such view (new.html.erb): <%= form_for @user, :url => teacher_leaders_url, :html => {:class => "form-horizontal"} do |f| %> <%= field_set_tag do %> <% f.fields_for :teacher_leader do |tl| %> <div class="control-group"> <%= tl.label :teacher_id, "Teacher names", :class => "control-label" %> <div class="controls"> <%= select_tag( :teacher_id, options_for_select( @teachers_collection, @choosen_teacher )) %> </div> </div> <% end %> <div class="control-group"> <%= f.label :user_login, "Login", :class => "control-label" %> <div class="controls"> <%= f.text_field :user_login, :placeholder => @everpresent_field_placeholder %> </div> </div> <div class="control-group"> <%= f.label :password, "Pass", :class => "control-label" %> <div class="controls"> <%= f.text_field :password, :placeholder => @everpresent_field_placeholder %> </div> </div> <% end %> <%= f.submit "Create", :class => "btn btn-large btn-success" %> <% end %> Problem is that select form here does NOT appear. Why? Do i do something wrong?

  • Subdomains vs. subdirectory – status as of 2012.

    - by Quintin Par
    This following question by Jeff was in 2010 and I wanted to check how things have changed in the past 2 years. My problem: I run a site with most of the content distributed to subdomains that’s are user based. E.g: Joe.example.com John.example.com Jil.example.com So all of these subdomains have the content and the main site example.com becomes a mere dummy listing all the subdomains. Now the question is, as of 2012, how is google treating domain authority and page rank in this case? I understand the notion of page rank as page per se but when it comes to domain authority will the parent domain have the cumulative effect of the domain authority or will it be spread out?

  • The changing shape of the Business Intelligence marketplace: Applications vs. Platforms

    - by GavinPayneUK
    I recently read the latest Gartner Magic Quadrant for Business Intelligence ( link ) which put Microsoft as a leader.  However, what was more interesting for me than Microsoft’s success was how as an industry we see BI as a single marketplace, business requirement and vision, despite in my view it now being two separate areas: BI applications and BI platforms . As this article will discuss in more depth we now have two communities with differing requirements, our IT departments and our business...(read more)

  • Customer Loyalty vs. Customer Engagement: Who Cares?

    - by Jeb Dasteel-Oracle
    Have you read the recent Forbes OracleVoice blog titled Customer Loyalty is Dead. Long Live Engagement!? If you haven’t, take a look. This article prompted lots of conversation in the social realm. Many who read the article voiced their reactions to the headline and now I’m jumping in to add my view. Normal 0 false false false EN-US X-NONE X-NONE Customer loyalty is still key. It’s the effect and engagement is the cause. We at least know that to be true for our customers. We are in an age where customers are demanding to be heard. We need them to be actively involved – or engaged – as well. Greater levels of customer engagement, properly targeted, positively correlate with satisfaction. Our data has shown us this over and over. Satisfied customers are more loyal and more willing to vocalize their satisfaction through referencing, and are more likely to purchase again, all of which in turn drives incremental revenue – from the customer doing the referencing AND the customer on the receiving end of that reference. Turning this around completely, if we begin to see the level of a customer’s engagement start to wane, this is an indicator that their satisfaction, loyalty, and future revenue are likely at risk. At Oracle, we’ve put in place many programs to target, encourage, and then track engagement, allowing us to measure engagement as a determinant of loyalty. Some of these programs include our Key Accounts, solution design and architectural, Executive Sponsorship, as well as executive advisory boards. Specific programs allow us to engage specific contacts within specific customer organizations (based on role) and then systematically track their engagement activities over time, along side of tracking customer satisfaction, loyalty, referenceability, and incremental revenue contribution. Continuous measurement of engagement allows us to better understand customer views of what it means to partner with a provider and adjust program participation to better meet the needs of the partnership. We can also track across customer segments, and design new programs that are even more effective than the ones we have in place today. In case you missed any of my previous Forbes articles, I’ve included links below for easy access.

  • EE vs Computer Science: Effect on Developers' Approaches, Styles?

    - by DarenW
    Are there any systematic differences between software developers (sw engineers, architect, whatever job title) with an electronics or other engineering background, compared to those who entered the profession through computer science? By electronics background, I mean an EE degree, or a self-taught electronics tinkerer, other types of engineers and experimental physicists. I'm wondering if coming into the software-making professions from a strong knowledge of flip flops, tristate buffers, clock edge rise times and so forth, usually leads to a distinct approach to problems, mindsets, or superior skills at certain specialties and lack of skills at others, when compared to the computer science types who are full of concepts like abstract data types, object orientation, database normalization, who speak of "closures" in programming languages - things that make little sense to the soldering iron crowd until they learn enough programming. The real world, I'm sure, offers a wild range of individual exceptions, but for the most part, can you say there are overall differences? Would these have hiring implications e.g. (to make up something) "never hire an electron wrangler to do database design"? Could knowing about any differences help job seekers find something appropriate more effectively? Or provide enlightenment or some practical advice for those who find themselves misfits in a particular job role? (Btw, I've never taken any computer science classes; my impression of exactly what they cover is fuzzy. I'm an electronics/physics/art type, myself.)

  • How should I model an economy-based game in code?

    - by Matthew G.
    I'd like to create an economy game based on an ancient civilization. I'm not sure how to design it. If I were working on a smaller game, like a copy of "Space Invaders," I'd have no problem structuring it like this: Main Control Class Graphics Class Player Class Enemy class I don't understand how I'd do this for larger projects like my economy game. Do I create a country class that contains a bunch of towns? Do the towns contain a lot building class, most contain classes of people? Do I make a path finding class that the player can access to get around?

  • Drupal Blog vs. WordPress Blog for a Drupal Website? [closed]

    - by Norma Riter
    Is there a blog of preference for SEO, when it comes down to Drupal websites. I ask as WordPress seems to have the better plug-ins, though may not integrate as well. Any thoughts on this? I am asking from primarily a SEO perspective though also a design one as well. In other words, there are so many fabulous blog templates in WordPress and not sure if there are in Drupal. I seem to be having a struggle finding Drupal blogs to purchase, such as premium blogs.

  • Pros and cons of PHP vs C,C++ as language in a programming interview ?

    - by DhruvPathak
    Hi All, Though this is a matter of personal choice and comfort. I would want your views on a situation like this. Programmer A has been working on PHP for some years, and has had prior experience in C.C++ during algorithm courses in university. The current fluency is good is PHP,but C,C++ can also be brushed up. So for interviews with major companies who put lot of emphasis on algorithms and data structures in programming interview e.g. binary trees, linked lists, arrays , strings . What should programmer A do ? Try to implement those things in PHP ( which is generally more suited for web development rather than programming contests/interviews ) or Or brush up the C,C++ skills and keep them as primary tool for tackling interview questions. What are advantages/ disadvantages of each language for an environment like programming contest or an interview ? Why would you recommend,not recommend Programmer A to participate in a contest like google code Jam/ ACM ICPC using PHP instead of C++ ? ( assuming PHP is allowed as a language there)

  • 4K sectors transition: Why are hard drives moving to 4096 byte sectors, vs. 512 byte sectors?

    - by Chris W. Rea
    I've noticed that some Western Digital hard drives are now sporting 4K sectors, that is, the sectors are larger: 4096 bytes vs. the long-standing standard of 512 bytes. So: What's the big deal with 4K sectors? Is it marketing hype, or a real advantage? Why should somebody building a new PC care, or not, about 4K sectors? Why is this transition taking place now? Why didn't it happen sooner? Are there things to look out for when buying a 4K sector hard drive? e.g. incompatibility? Anything else we should know about 4K sectors?

  • C#: why Base class is allowed to implement an interface contract without inheriting from it?

    - by etarassov
    I've stumbled upon this "feature" of C# - the base class that implements interface methods does not have to derive from it. Example: public interface IContract { void Func(); } // Note that Base does **not** derive from IContract public abstract class Base { public void Func() { Console.WriteLine("Base.Func"); } } // Note that Derived does *not* provide implementation for IContract public class Derived : Base, IContract { } What happens is that Derived magically picks-up a public method Base.Func and decides that it will implement IContract.Func. What is the reason behind this magic? IMHO: this "quasi-implementation" feature is very-unintuitive and make code-inspection much harder. What do you think?

  • Computer Science Career Advice: Master's in Computer Science vs. Software Engineering?

    - by Everton
    Hello, I am a college student and I am majoring in Computer Science and Applied Mathematics. As I get closer to my senior year I have noticed that continuing my studies is the best choice right for me now. I see that several universities offer an Computer Science Master's Degree and an Software Engineering degree. What are their pros and cons? I feel that while the Computer Science master's degree seems a little too broad the Software Engineering is too restrictive. I did not decide yet between an career of Software development or research ( algorithm development among other things ). Any advice would be greatly apreciated!

  • How do I make the correct career decision in regards to product manager/QA vs programmer?

    - by Adel
    I'm curious about how to approach the issue of whether I should focus on programming or on QA/testing/product management. I know that the latter seems like a broad category( if so, think of it as "general IT support" for now). At the moment I'm stronger in QA/prod. mgt ; however I'd like to switch more to programming, and I see I may have this opportunity. Wouldn't it be easier to switch to QA/prod. mgt in the future, if I go into programming now; rather than trying the reverse-order(i.e. if I decided later to go into coding.. say around mid-30s then it'd likely be harder). Just looking for any advice or tips about how to see more clearly. Part of me is scared I can't handle the programming side, but part of me says since there's demand and I'm interested that it's still worth a shot.

  • Why are static classes considered “classes” and “reference types”?

    - by Timwi
    I’ve been pondering about the C# and CIL type system today and I’ve started to wonder why static classes are considered classes. There are many ways in which they are not really classes: A “normal” class can contain non-static members, a static class can’t. In this respect, a class is more similar to a struct than it is to a static class, and yet structs have a separate name. You can have a reference to an instance of a “normal” class, but not a static class (despite it being considered a “reference type”). In this respect, a class is more similar to an interface than it is to a static class, and yet interfaces have a separate name. The name of a static class can never be used in any place where a type name would normally fit: you can’t declare a variable of this type, you can’t use it as a base type, and you can’t use it as a generic type parameter. In this respect, static classes are somewhat more like namespaces. A “normal” class can implement interfaces. Once again, that makes classes more similar to structs than to static classes. A “normal” class can inherit from another class. It is also bizarre that static classes are considered to derive from System.Object. Although this allows them to “inherit” the static methods Equals and ReferenceEquals, the purpose of that inheritance is questionable as you would call those methods on object anyway. C# even allows you to specify that useless inheritance explicitly on static classes, but not on interfaces or structs, where the implicit derivation from object and System.ValueType, respectively, actually has a purpose. Regarding the subset-of-features argument: Static classes have a subset of the features of classes, but they also have a subset of the features of structs. All of the things that make a class distinct from the other kinds of type, do not seem to apply to static classes. Regarding the typeof argument: Making a static class into a new and different kind of type does not preclude it from being used in typeof. Given the sheer oddity of static classes, and the scarcity of similarities between them and “normal” classes, shouldn’t they have been made into a separate kind of type instead of a special kind of class?

  • A good class structure for cleaning and using input?

    - by ciscoheat
    I want to be helpful to the users of a system, so I'll clean up the input a bit before testing if it can be used. So I have a flow like this: Input: aa12345b Clean input somehow: 12345 Test if clean input is valid Use input if valid Now I want to do this in a beautiful OO-fashion (IoC, interfaces, testable, no statics, you know). Any ideas how to organize a class structure for this? Is it good to have a Cleaner and a Parser/Validator class separately, or put them as methods in the data class itself? Thanks for any help or discussion about this, and extra thanks if the answer is in C#!

  • compare function for dates

  • Android: setting up a google map class. bit of advice required.

    - by Capsud
    Hey there, Ok so this is what i've got. Button anandabutton = (Button) findViewById(R.id.anandaAddressButton); anandabutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); startActivityForResult(myIntent,0); } }); This method opens up my MapClass class which at the moment I just have set to show the location of one place. But I have a load of buttons and rather than making a lot of different mapClass classes for each button, I am wondering can I just use the one class and depending on what button 'id' is pressed, it will check an 'if statement' and then put in the correct coordinates into the method to display the map. It would be a lot neater than coding up like 20-30 classes. I'm not sure if i've explained that right so if not let me know. Thanks for any help.
