• Why do some people hate Dart? [closed]

  - by Hassan

  First, I'd like to note that this question is not intended to compare two languages or technologies, but is only asking about criticisms aimed at a language. I've always thought it a good idea to somehow get rid of Javascript. It works, but it's just so messy. I think many will agree with me there. And that's how I interpreted Google's release of Dart. It seems to me like a very good alternative to Javascript. Now, it looks like some are not very happy that Google has released this new language. Take a look at this Wikipedia page to see what I'm talking about. If you don't feel like reading it, I'll tell you now that some seem to think that Dart is similar to Microsoft's VBScript, in that it only works on Microsoft's browsers. This goes against the web's openness. But it's my understanding that Dart can be compiled to Javascript, which will allow it to be run on any modern browser (as the Wikipedia article also states). So my question is: are these criticisms valid? Is there a real fear that Google is trying to control the web's front-end to be more compatible with its browser?

• Triangle Strips and Tangent Space Normal Mapping

  - by Koarl

  Short: Do triangle strips and Tangent Space Normal mapping go together? According to quite a lot of tutorials on bump mapping, it seems common practice to derive tangent space matrices in a vertex program and transform the light direction vector(s) to tangent space and then pass them on to a fragment program. However, if one was using triangle strips or index buffers, it is a given that the vertex buffer contains vertices that sit at border edges and would thus require more than one normal to derive tangent space matrices to interpolate between in fragment programs. Is there any reasonable way to not have duplicate vertices in your buffer and still use tangent space normal mapping? Which one do you think is better: Having normal and tangent encoded in the assets and just optimize the geometry handling to alleviate the cost of duplicate vertices or using triangle strips and computing normals/tangents completely at run time? Thinking about it, the more reasonable answer seems to be the first one, but why might my professor still be fussing about triangle strips when it seems so obvious?

• Why C++ is an abomination [closed]

  - by Chander Shivdasani

  Possible Duplicate: Why do so many people dislike C++? I was reading the blog by Peter Seibel (Author of Coders at Work) where brilliant programmers like Ken Thompson, Joshua Bloch and Guy Steele have despised c++ to no end. What is it in C++ that people hate so much? And despite so much hate towards it, companies like Google are still using it, and some of the programmers who snubbed C++ have worked or are already working at Google. So, what is it in the language that despite so much hate from top programmers, it's still used at most of the places? I haven't really used C++ beyond academic projects, so i don't know much about the disadvantages of the language. What do programmers here think about it? --Chander

• What could be the Java successor Oracle wants to invest in?

  - by deamon

  I've read that Oracle wants to invest into another language than Java: "On the other hand, Oracle has been particularly supportive of alternative JVM languages. Adam Messinger ( http://www.linkedin.com/in/adammessinger ) was pretty blunt at the JVM Languages Summit this year about Java the language reaching it's logical end and how Oracle is looking for a 'higher level' language to 'put significant investment into.'" But what language could be the one Oracle wants to invest in? Is there another candidate than Scala?

• Installing Solaris Studio 12.2 on Ubuntu 10.04

  - by KronoS

  I'm having a dickens of a time installing Solaris Studio 12.2 on Ubuntu 10.04. I found this guide, however using the alien option isn't finding the correct files. I'm not exactly sure on the syntax of alien, its kinda alien to me. (sorry for the bad pun) Also, when I download the tar file, and extract it, there are errors everytime saying things like: "operation not permitted" cannot creat symlink to '../prod/bin/cc': Operation not permitted I've extracted with super user access, but to no avail. Any success from anyone else?

• How to handle mutiple API calls using javascript/jquery

  - by James Privett

  I need to build a service that will call multiple API's at the same time and then output the results on the page (Think of how a price comparison site works for example). The idea being that as each API call completes the results are sent to the browser immediately and the page would get progressively bigger until all process are complete. Because these API calls may take several seconds each to return I would like to do this via javascript/jquery in order to create a better user experience. I have never done anything like this before using javascript/jquery so I was wondering if there was any frameworks/advice that anyone would be willing to share.

• Purpose of "new" keyword

  - by Channel72

  The new keyword in languages like Java, Javascript, and C# creates a new instance of a class. This syntax seems to have been inherited from C++, where new is used specifically to allocate a new instance of a class on the heap, and return a pointer to the new instance. In C++, this is not the only way to construct an object. You can also construct an object on the stack, without using new - and in fact, this way of constructing objects is much more common in C++. So, coming from a C++ background, the new keyword in languages like Java, Javascript, and C# seemed natural and obvious to me. Then I started to learn Python, which doesn't have the new keyword. In Python, an instance is constructed simply by calling the constructor, like: f = Foo() At first, this seemed a bit off to me, until it occurred to me that there's no reason for Python to have new, because everything is an object so there's no need to disambiguate between various constructor syntaxes. But then I thought - what's really the point of new in Java? Why should we say Object o = new Object();? Why not just Object o = Object();? In C++ there's definitely a need for new, since we need to distinguish between allocating on the heap and allocating on the stack, but in Java all objects are constructed on the heap, so why even have the new keyword? The same question could be asked for Javascript. In C#, which I'm much less familiar with, I think new may have some purpose in terms of distinguishing between object types and value types, but I'm not sure. Regardless, it seems to me that many languages which came after C++ simply "inherited" the new keyword - without really needing it. It's almost like a vestigial keyword. We don't seem to need it for any reason, and yet it's there. Question: Am I correct about this? Or is there some compelling reason that new needs to be in C++-inspired memory-managed languages like Java, Javascript and C#?

• Starting to make 2D games in C++

  - by Ashley

  I'm fairly experienced with C and C#, but I've only ever created console/windows applications. I'm also experienced with AS3 and I've made some flash games. I want to make proper 2D games in C++, but I have no idea where to begin with graphics. There are entire books devoted to game development in C++ that only work with console applications and I'm finding the lack of resources and tutorials for proper 2D games frustrating... I'm also not particularly interested in using existing engines because I want total control of what I create. I've heard of the Allegro library; is it something important/popular that I should look into? How will I use DirectX? Any resources or links to tutorials or information is greatly appreciated.

• Using XNA to learn to build a game, but wanna move on [closed]

  - by Daniel Ribeiro

  I've been building a 2D isometric game (with learning purposes) in C# using XNA. I found it's really easy to manage sprite sheets loading, collision, basic physics and such with the XNA api. The thing is, I want to move on. My real goal is to learn C++ and develop a game using that language. What engine/library would you guys recommend for me to keep going on that same 2D isometric game direction using pretty much sprite sheets for the graphical part of the game?

• if/else statements or exceptions

  - by Thaven

  I don't know, that this question fit better on this board, or stackoverflow, but because my question is connected rather to practices, that some specified problem. So, consider an object that does something. And this something can (but should not!) can go wrong. So, this situation can be resolved in two way: first, with exceptions: DoSomethingClass exampleObject = new DoSomethingClass(); try { exampleObject.DoSomething(); } catch (ThisCanGoWrongException ex) { [...] } And second, with if statement: DoSomethingClass exampleObject = new DoSomethingClass(); if(!exampleObject.DoSomething()) { [...] } Second case in more sophisticated way: DoSomethingClass exampleObject = new DoSomethingClass(); ErrorHandler error = exampleObject.DoSomething(); if (error.HasError) { if(error.ErrorType == ErrorType.DivideByPotato) { [...] } } which way is better? In one hand, I heard that exception should be used only for real unexpected situations, and if programist know, that something may happen, he should used if/else. In second hand, Robert C. Martin in his book Clean Code Wrote, that exception are far more object oriented, and more simple to keep clean.

• Why Adobe Air is so underrated for building mobile apps?

  - by Marcelo de Assis

  I worked with Adobe Flash related technologies for the last 5 years, although not being a big fan of Adobe. I see some little bugs happening in some apps, but I cannot imagine why a lot of big companies do not even think to use use Adobe Air as a good technology for their mobile apps. I see a lot of mobile developer positions asking for experts in Android or iOS , but very much less positions asking for Adobe Air, even when Adobe Air apps have the advantage of being multi-plataform, with the same app working in Blackberry, iOS and Android. Is so much easier to develop a game using Flash, than using Android SDK, for example. It really have flaws (that I never saw) or it is just some kind of mass prejudgement? I also would like to hear what a project manager or a indie developer takes when choosing a plataform for building apps.

• Is committing/checking code everyday a good practice?

  - by ArtB

  I've been reading Martin Fowler's note on Continuous Integration and he lists as a must "Everyone Commits To the Mainline Every Day". I do not like to commit code unless the section I'm working on is complete and that in practice I commit my code every three days: one day to investigate/reproduce the task and make some preliminary changes, a second day to complete the changes, and a third day to write the tests and clean it up^ for submission. I would not feel comfortable submitting the code sooner. Now, I pull changes from the repository and integrate them locally usually twice a day, but I do not commit that often unless I can carve out a smaller piece of work. Question: is committing everyday such a good practice that I should change my workflow to accomodate it, or it is not that advisable? ^ The order is more arbitrary and depends on the task, my point was to illustrate the time span and activities, not the exact sequence.

• How to have a maintainable and manageable Javascript code base

  - by dade

  I am starting a new job soon as a frontend developer. The App I would be working on is 100% Javascript on the client side. all the server returns is an index page that loads all the Javascript files needed by the app. Now here is the problem: The whole of the application is built around having functions wrapped to different namespaces. And from what I see, a simple function like rendering the HTML of a page can be accomplished by having a call to 2 or more functions across different namespace... My initial thought was "this does not feel like the perfect solution" and I can just envisage a lot of issues with maintaining the code and extending it down the line. Now I would soon start working on taking the project forward and would like to have suggestions on good case practices when it comes to writing and managing a relatively large amount of javascript code.

• Why should I use List<T> over IEnumerable<T>?

  - by Rowan Freeman

  In my ASP.net MVC4 web application I use IEnumerables, trying to follow the mantra to program to the interface, not the implementation. Return IEnumerable(Of Student) vs Return New List(Of Student) People are telling me to use List and not IEnumerable, because lists force the query to be executed and IEumerable does not. Is this really best practice? Is there any alternative? I feel strange using concrete objects where an interface could be used. Is my strange feeling justified?

• How to handle a player's level and its consequent privileges?

  - by Songo

  I'm building a game similar to Mafia Wars where a player can do tasks for his gang and gain experience and thus advancing his level. The game is built using PHP and a Mysql database. In the game I want to limit the resources allowed to player based on his level. For example: ________| (Max gold) | (Max army size) | (Max moves) | ... Level 1 | 1000 | 100 | 10 | ... Level 2 | 1500 | 200 | 20 | ... Level 3 | 3000 | 300 | 25 | ... . . . In addition certain features of the game won't be allowed until a certain level is reached such as players under Level 10 can't trade in the game market, players under Level 20 can't create alliances,...etc. The way I have modeled it is by implementing a very loooong ACL (Access Control List) with about 100 entries (an entry for each level). However, I think there may be a simpler approach to this seeing that this feature have been implemented in many games before.

• Is it better to build HTML Code string on the server or on the client side?

  - by Ionut

  The result of the following process should be a html form. This form's structure varies from one to user. For example there might be a different number of rows or there may be the need for rowspan and colspan. When the user chooses to see this table an ajax call is made to the server where the structure of the table is decided from the database. Then I have to create the html code for the table structure which will be inserted in the DOM via JavaScript. The following problem comes to my mind: Where should I build the HTML code which will be inserted in the DOM? On the server side or should I send some parameters in the ajax call method and process the structure there? Therefore the main question involves good practice when it comes to decide between Server side processing or client side processing. Thank you!

• Is reference to bug/issue in commit message considered good practice?

  - by Christian P

  I'm working on a project where we have the source control set up to automatically write notes in the bug tracker. We simply write the bug issue ID in the commit message and the commit message is added as a note to the bug tracker. I can see only a few downsides for this practice. If sometime in the future the source code gets separated from the bug tracking software (or the reported bugs/issues are somehow lost). Or when someone is looking in the history of commits but doesn't have access to our bug tracker. My question is if having a bug/issue reference in the commit message is considered good practice? Are there some other downsides?

• Is Linq having a mind-numbing effect on .NET programmers?

  - by Aaronaught

  A lot of us started seeing this phenomenon with jQuery about a year ago when people started asking how to do absolutely insane things like retrieve the query string with jQuery. The difference between the library (jQuery) and the language (JavaScript) is apparently lost on many programmers, and results in a lot of inappropriate, convoluted code being written where it is not necessary. Maybe it's just my imagination, but I swear I'm starting to see an uptick in the number of questions where people are asking to do similarly insane things with Linq, like find ranges in a sorted array. I can't get over how thoroughly inappropriate the Linq extensions are for solving that problem, but more importantly the fact that the author just assumed that the ideal solution would involve Linq without actually thinking about it (as far as I can tell). It seems that we are repeating history, breeding a new generation of .NET programmers who can't tell the difference between the language (C#/VB.NET) and the library (Linq). What is responsible for this phenomenon? Is it just hype? Magpie tendencies? Has Linq picked up a reputation as a form of magic, where instead of actually writing code you just have to utter the right incantation? I'm hardly satisfied with those explanations but I can't really think of anything else. More importantly, is it really a problem, and if so, what's the best way to help enlighten these people?

• What's a nice explanation for pointers?

  - by Macneil

  In your own studies (on your own, or for a class) did you have an "ah ha" moment when you finally, really understood pointers? Do you have an explanation you use for beginner programmers that seems particularly effective? For example, when beginners first encounter pointers in C, they might just add &s and *s until it compiles (as I myself once did). Maybe it was a picture, or a really well motivated example, that made pointers "click" for you or your student. What was it, and what did you try before that didn't seem to work? Were any topics prerequisites (e.g. structs, or arrays)? In other words, what was necessary to understand the meaning of &s and *, when you could use them with confidence? Learning the syntax and terminology or the use cases isn't enough, at some point the idea needs to be internalized. Update: I really like the answers so far; please keep them coming. There are a lot of great perspectives here, but I think many are good explanations/slogans for ourselves after we've internalized the concept. I'm looking for the detailed contexts and circumstances when it dawned on you. For example: I only somewhat understood pointers syntactically in C. I heard two of my friends explaining pointers to another friend, who asked why a struct was passed with a pointer. The first friend talked about how it needed to be referenced and modified, but it was just a short comment from the other friend where it hit me: "It's also more efficient." Passing 4 bytes instead of 16 bytes was the final conceptual shift I needed.

• Does a mature agile team requires any management?

  - by ashy_32bit

  After a recent heated debate over Scrum, I realized my problem is that I think of management as a quite unnecessary and redundant activity in a fully agile team. I believe a mature Agile team does not require management or any non-technical decision making process whatsoever. To my (apparently erring) eyes it is more than obvious that the only one suitable and capable of managing a mature development team is their coach (who is the most technically competent colleague with proper communication skills). I can't imagine how a Scrum master can contribute to such a team. I am having great difficulty realizing and understanding the value of such things in Scrum and the manager as someone who is not a veteran developer but is well skilled in planning the production cycles when a coach exists in the team. What does that even mean? How on earth can someone with no edge-skills of development manage a highly technical team? Perhaps management here means something else? I see management as a total waste of time and a by-product of immaturity. In my understanding a mature team is fully self-managing. Apparently I'm mistaken since many great people say the contrary but I can't convince myself.

• What attracts software developers such as yourselves to choose to program for the Android mobile platform?

  Dear programmers, as part of my final year university project, I am conducting research into what makes programmers prefer to program for Android as opposed to other mobile operating systems. The description does not need to be detailed however, I am trying to find patterns between programmers to determine what properties (other than money) a software company such as Android must have in order to attract programmers and therefore grow.

• Someone tell me why people writing GNU code use { like that?

  - by Deus Deceit

  I saw the rules on how to type code for UNITY project or GNU software in general. Why do they write code in such an ugly form? Is there a particular reason why they don't put brackets the way (from what I know) most people do? Why like this: for (i = 0; i < 5; i++) { //do something } and not like this: for (i = 0; i < 5; i++) { //Do something } or this: for(i = 0; i < 5l i++) { //Do Something } ???

• Why are people using C instead of C++? [closed]

  - by Darth

  Possible Duplicate: When to use C over C++, and C++ over C? Many times I've stumbled upon people saying that C++ is not always better than C. Great example here would be the Linux kernel, where they simply decided to use C instead of C++ because it had better compilers at the time. But that's many years ago and a lot has changed. So the question is, why are people still using C over C++? I gues there are probably some cases (like embedded devices), where there simply isn't a good C++ compiler, or am I wrong here? What are the other cases when it is better to go with C instead of C++?

• Should I provide fallbacks for HTML5/CSS3 elements in a web page at this point?

  - by Abluescarab

  I'm wondering if I should bother providing a fallback for HTML5 tags and attributes and CSS3 styling at this point in time. I know that there's probably still a lot of people out there who use older versions of browsers and HTML5/CSS3 are still fairly new. I read this article: Should I use non-standard tags in a HTML page for highlighting words? and one answer mentioned that people kind of "cheat" with older browsers by using the new tags and attributes, but styling them in CSS to ensure they show up right. This question: Relevance of HTML5: Is now the time? was asked about two years ago and I don't know how relevant it is anymore. For example, I want to use the placeholder and required attributes in a web form I'm building and it has no labels to show what each <input> is. How do I handle this, or do I bother?

• Tangent basis calculation problem

  - by Kirill Daybov

  I have the problem with seams with calculating a tangent basis in my application. I'm using a seems to be right algorithm, but it gives wrong result on the seams. What am I doing wrong? Is there a problem with an algorithm, or with the model? The designer says that our models with our normal maps are rendered correctly in Xoliul Shader Plugin in 3Ds Max, so there should be a way to calculate correct tangent basis programmatically. Here's an example of the problem I'm talking about. Steps, I've already taken: - Tried different algorithm (from Gamasutra, I can't post the link because I don't have enough reputation yet). I got wrong, much worse, results; - Tried to average basis vectors for vertexes are used in multiple faces; - Tried to average basis vectors for vertexes that have same world coordinates (this would be obviously wrong solution, but I've tried it anyway).
