• What would you call the concept of CofeeScript or Sass to be?

  - by MaG3Stican

  There is this rising trend with web development of making new pseudo languages to extend the functionality of JavaScript, CSS and HTML given that those are static and their metamorphosis or evolution is painfully slow due to the variety of browser providers. So I am currently having a concept dilema on how to categorize them for a book I was made to write by my employer as no one seems to have a name for these pseudo languages. A tiny list of them : JavaScript: LiveScript, Metalua, Uberscript, EmberScript. HTML: Razor, Java Scriptlets. CSS : LESS, Sass. I believe the concept of these pseudo languages and a language or an extension of a language is quite different. First these languages do not extend any functionality currently existing on HTML or CSS or JavaScript, they simply work around it. And also they do not "compile" to an intermediate language, they are merely 1-1 translated to something that only then can be compiled. What would you call them?

• What's your advice in getting Oracle Certified Professional Java Programmer certificate?

  - by den-javamaniac

  Hi. I'm intending to get the certification but not completely sure how to time effectively prepare myself. So I'm wondering if I can be advised on the matter, in particular I would like next questions to be answered: - What the basic learning/practicing plan should look like? - What book (set of books) should be considered? - What practical exercises should be performed? NOTE: I've got several years of corporate experience (mostly web apps, though), but I want to be 100% sure I'll pass the test (that's the reason the issue is raised).

• Application versioning

  - by Mathew

  Haven't find similar issue so sorry if thats a duplicate. I'm about to start a migration of an already existing project from one web container version to the another. Currently, the application version is 2.2.5. Business requirement is to deliver a 3.0 version by the end of the year. Additional constraint is to release a working, stable version by the end of Q3. We are about to work in 2-weeks sprints and I'm wondering how can I approach the problem? I was thinking about releasing 2.3 by the end of Q2, then immediately promoting it as 3.0-a1, work on alphas (3.0-a2, 3.0-a3, ...) till the end of Q3, to start with 3.0-b1 in the early Q4 and finally release 3.0 around December. I don't feel comfortable saying that the application is already in 3.0 state in July, but I can't see other options. If you find some book chapters/blogs or your personal experience interesting please share your opinion.

• Difference between '\n' and '\r\n'

  - by sukhbir

  Yes yes, I am aware that '\n' writes a newline in UNIX while for Windows there is the two character sequence: '\r\n'. All this is very nice in theory, but my question is why? Why the carriage return character is extra in Windows? If UNIX can do it in \n why does it take Windows two characters to do this? I am reading David Beazley's Python book and he says: For example, on Windows, writing the character '\n' actually outputs the two- character sequence '\r\n' (and when reading the file back, '\r\n' is translated back into a single '\n' character). Why the extra effort? I will be honest. I have known the difference for a long time but have never bothered to ask WHY. I hope that is answered today. Thanks for your time.

• Continuing Education as a Part of Your Job [closed]

  - by Mike

  I work as a programmer for a mid-sized company (about 500 employees) in the medical industry. Before that I worked at a custom software development/consulting company. At both companies programmers were never officially given time to continue their education through taking classes, reading books or blogs, or doing research relevant to the job. At the software development company we were offered some money to pay for a class, but not offered any time off of work to take the class. I have been wondering, do most employers of programmers give time off of work to take a class, read a book, or do job related research? By time off of work I just mean some period of time where you can stop development; it does not have to mean leaving the office. I would be grateful to hear about everyone's experience with this.

• How I improve my problem-solving ability

  - by gcc

  How we can improve our problem-solving ability ? Every one says same thing "real programmer knows how to handle real problem.", but they forget something how they take this ability, or where ( I know in school, no one gives us any ability, of course in my opinion. ) If you have any idea except above ones, feel free when you give an advice solve more problem do more exercise, write code, search google then write more ... For me, my question is like "Use complex/known library instead of using your own." In other words, I want your experience, book recommendation, web page

• How to learn to translate real world problems to code?

  - by StudioWorks

  I'm kind of a beginner to Java and OOP and I didn't quite get the whole concept of seeing a real world problem and translating it to classes and code. For example, I was reading a book on UML and at the beginning the author takes the example of a tic tac toe game and says: "In this example, it's natural to see three classes: Board, Player and Position." Then, he creates the methods in each class and explains how they relate. What I can't understand is how he thought all this. So, where should I start to learn how to see a real world problem and then "translate" it into code?

• Beginner help: where to begin [closed]

  - by shad

  I want to learn how to program. A main stream programming language such as Java, C++/C# is my primary target. Currently, I am a high school student planning to take programming, Digital electronics courses next semester. My biggest problem is that I do not know where to start and I have no one to consult with. Should I take a course at my local community college this summer? Get some books or try learning from some internet websites? What would be the best option a book or website? note that this is no longer my words, but rather ChrisF's because he decided to reword the question a bit (bad) and spaced it out better (good).

• Data-driven animations

  - by saadtaame

  Say you are using C/SDL for a 2D game project. It's often the case that people use a structure to represent a frame in an animation. The struct consists of an image and how much time the frame is supposed to be visible. Is this data sufficient to represent somewhat complex animation? Is it a good idea to separate animation management code and animation data? Can somebody provide a link to animations tutorials that store animations in a file and retrieve them when needed. I read this in a book (AI game programming wisdom) but would like to see a real implementation.

• Being hire-able [closed]

  - by RealityDysfunction

  Hello fellow developers, I am in my last year of Undergrad (Applied Math). I have discovered my passion for programming after taking a programming course (required by program), it was a basic Java course but I loved it! So I picked up an Apress C# Pro by Andrew Troelsen book. My degree is not in CompSci and I have under a year left to graduation. How do I prove myself as a programmer? What would you recommend I do in order to become hire-able?

• Instantiating Interfaces in C#?

  - by RealityDysfunction

  I am reading/learning about interfaces in C# at the moment, and thus far I managed to understand how it differs from an abstract class. In the book I am reading the author explains that interfaces are the ultimate abstract class and that it simply sets the standard of certain methods the inheriting class will have, but then provides the following example... static void Main(string[] args) { ... Circle c = new Circle("Lisa"); IPointy itPt = null; try { itPt = (IPointy)c; Console.WriteLine.(itPt.Points); } catch (InvalidCastException e) { Console.WriteLine(e.Message); } ... } The line that absolutely throws me off is the "IPointy itfPt=null;" did he just declare an interface??? I thought interfaces are abstract and can only be inherited? What kind of sorcery is going on here? Thanks for any help, I

• Advise on effectively re-entering CPP world [closed]

  - by Aadith

  I am getting back into C++ world after nearly a decade. Apparently, there has been a world of development. Would like to get the developer community's advice as to what would be a good approach to have a smooth take-off. To start with, I have done the following: Read up (very briefly) on C++ 11 standards Installed GCC 4.7 Wrote a Hello World program I am sure getting a decent book and reading through it would do. But I am looking for any strategic advise experts might have to share. Trying to leverage on past experience to have a short but effective initial learning span. What would be top few things I would have to look into?

• Why do we need private variables?

  - by rak

  Why do we need private variables in classes in the context of programming? Every book on programming I've read says this is a private variable, this is how you define it but stops there. The wording of these explanations always seemed to me like we really have a crisis of trust in our profession. The explanations always sounded like other programmers are out to mess up our code. Yet, there are many programming languages that do not have private variables. What do private variables help prevent? How do you decide if a particular of properties should be private or not? If by default every field SHOULD be private then why are there public data members in a class? Under what circumstances should a variable be made public?

• Where can I find crash course in Java eclipse in Vancouver?

  - by user3604

  I am not satisfied with what I learned in Java 101 in University. I feel like, lot of time is spent on trying to figure out how to write something in Java properly. I feel like, my lack of knowledge of Java and eclipse is slowing me down. I would like to pay for a detailed and intensive course in Java & Eclipse. I can read a book and read tutorials, but it seems harder to discipline myself. Where can I find such crash courses outside of university courses? I find lot of CS courses just show tip of the iceberg and not too much focused on actual application. I want to learn the latest industry skills and etc. I live in BC, Canada. I am thinking of BCIT, but not sure what they offer.

• SQL Why is prefixing column names considered bad practice?

  - by P.Brian.Mackey

  According to a popular SO post is it considered a bad practice to prefix table names. At my company every column is prefixed by a table name. This is difficult for me to read. I'm not sure the reason, but this naming is actually the company standard. I can't stand the naming convention, but I have no documentation to back up my reasoning. All I know is that reading AdventureWorks is much simpler. In this our company DB you will see a table, Person and it might have column name: Person_First_Name or maybe even Person_Person_First_Name (don't ask me why you see person 2x) Why is it considered a bad practice to pre-fix column names? Are underscores considered evil in SQL as well? Note: I own Pro SQL Server 2008 - Relation Database design and implementation. References to that book are welcome.

• What language should an 11-year old start with to learn game programming?

  - by emsr

  I have a 11-year old son who wants to do game programming. I've started him on C++ (C++11) and he's learned iostreams, looping, functions, logic and flow control. I'm using the standard library and no memory management at all. But I would like to ask: What language would you suggest for a pre-teen (Python, ...)? What books would you suggest? We looked at one book that was just for console ASCII games. I liked the C++ that it taught but I think he'll get bored without some graphics at some point.

• Preparing for Interview: I feel like, I wanna start coding all data structures again.... Is it a right way to start?

  - by howtechstuffworks

  I started preparing for my interview. I will be graduating this May. Right now, I am doing an internship in an product based company, so I did my fair share of preparation. The thing is, whenever, I try to do something, I always think that I should start everything from page 1. It is sometimes not at all helpful.... For example, reading a programming book from page 1 is not going to helpful, as I never completed one and always stopped half way through or rushed through towards deadlines. I am facing a similar situation now. I feel like, I wanna start coding all data structures from first(I attempted and finished atleast 6-7 last fall, preparing for interview). Now I feel like, I wanna code everything from first, instead of attempting something new.... I am not quite sure, what this is, but this is the way I have been..... LOL

• Which version of OpenGL for Android?

  - by akadouri

  I've been trying to learn OpenGL ES 2.0 to create a simple 2D game. I bought a book on android development, but after seeing that the author uses his own SDK that implements OpenGL ES 1.0 I decided to just use online tutorials. I've been so lost trying to find out what to use. The Matrices and shaders of 2.0 confuse me and I can't find any tutorial that just explains how to texture map a simple 2D image. Basically: OpenGL ES 1.x or 2.0 for simple 2D with little OpenGL experience If 2.0 Any good tutorials for 2.0, I've found so many for 1.0
