• When should I increment version number?

  - by ahmed

  I didn't learn programming at school and I do not work as a (professional) developer, hence a lot of basics are not quite clear to me. This question tries to clarify one of them. Now let's suppose that I have issues #1, #2 and #3 in my Issues Tracker that are set to be corrected/enhanced for version 1.0.0 and that the last (stable) version is 0.9.0. When should I increment to version 1.0.0 ? When a) just one of the listed above issues is closed or b) when all the issues related to version 1.0 are closed ? Which one is the right way to do it ? And by the right way, I mean what is currently used in the industry. Thanks.

• Over a million COBOL porgrammers in the world?

  - by Lucas McCoy

  I think I heard on a previous StackOverflow podcast that COBOL was used as the programming language for traffic lights (or something like that), so this got me interested. I did a quick Google search and found this little article: Today, Cobol is everywhere, yet largely unheard of by millions of people who interact with it daily when using the ATM, stopping at traffic lights or buying a product online. The statistics on Cobol attest to its huge influence on the business world: There are over 220 billion lines of Cobol in existence, a figure which equates to about 80 per cent of the world’s actively used code. There over a million Cobol programmers in the world. There are 200 times as many Cobol transactions that take place each day than Google searches. I didn't really trust the source seeing as how it's on some random PHPBB forum. So how accurate are these figures? Are there really 220 billion lines of COBOL? I assume a few people/companies still use COBOL, but how many?

• Having MSc or Bsc with Experience, whats worth in industrial environments?

  - by Abimaran

  I'm a fresh graduate in Electronic & Telecommunication field, and in our University, we can have major and minor fields in the relevant subjects. So, I majored in telecommunication and minored in Software Engineering. As I learned programing long before, Now I'm passionate in SE and programming. And, I want drive into the SE field. And, It came to know that, in industries, most of them expecting the candidates to have the Bsc + experience of two+ years, or having a MSc in the related field. [I'm referring my surrounding environment, not all the industries]. My Question, How do they consider those MSc and BSc + experience guys in the industries? IMO, having MSc is great assert with comparing to have experience. Because, in the industry, you can drive in a particular technology (Java, .Net or some thing else), not all, and with MSc, we can get the domain knowledge, not a particular technology! Thanks!

• Why does a computer science degree matter to a professional programmer?

  - by P.Brian.Mackey

  I have a degree in computer science. It has been great for opening doors, getting a job. As far as helping me in the professional field of C# .NET programming (the most popular platform and language in the area I work if not the entire united states on hands down the most popular OS in the world) its hardly useful. Why do you think it helps you as a programmer in your professional career (outside spouting off to prims algorithm to impress some interviewer)? In today's world adaptation, a quick mind, strong communication, OO and fundamental design skills enable a developer to write software that a customer will accept. These skills are only skimmed over in the cs program. In my mind, reading a 500 page C# book by Wrox offers far more useable a skillset than 4 years of the comp sci math blaster courses. Many disagree. So, why does a computer science degree matter?

• Website Stopped Showing From Google Search Results Sunddenly

  - by Aman Virk

  I have a design and development blog http://www.thetutlage.com (1.5 years old), which was doing really well in Google search as I was getting over 70% of my traffic from Google. Now suddenly from last two days it reduced the amount of traffic from 70% to 20% and also when I am trying to search for the exact posts that I can created even after appending my website name to it does not show any results for that. Sample Search Text: JQuery Game Programming Creating A Ping Pong Game Part 1 I have post with exact same title and it does not show it on Google search anywhere. I am totally shocked, I write my own unique content and follow Google guide lines like bible. Also there is no message under my webmasters account stating any problem or error.

• Which version of Ubuntu is recommended for app developers?

  - by Wes

  I've searched around Ask Ubuntu and the App Developer site, but I can't seem to find the answers to my questions. I'm wanting to get back into programming, and I'd eventually like get into app development for Ubuntu, but I'm not sure where to get started. Which version of Ubuntu is currently recommended for app development, especially for those wanting to publish their apps to the Software Centre? Should app developers use the current LTS release, or, can any of the new releases be used? Should developers use the 32-bit or 64-bit edition of Ubuntu, or does this not matter? What effect would the above choices have on the eventual publication of an app? I'm truly sorry if this has been covered elsewhere. Cheers Wes

• Is Windows 7 written in Xaml? [closed]

  - by Jordan

  Is Windows 7 written using Xaml? Edit Wow, so much hate for such a little question. I'm not an idiot. I know what XAML is. I use it every day. I was just curious whether some of the visual features were laid out with XAML, or if XAML was incorporated in some way to the product. I'm sorry if it is a programming sin not to know what Windows 7 was written in. I mean, I know Windows XP et al used C++/C, I've used Win32 quite a lot (and MFC and .NET).

• Redirect AFTER Initiating download

  - by mashup

  I have a question - is there any way to initiate a download and AFTER the user has confirmed the download then redirect to another site? Is something like that possible via ASP or another language commonly used for websites? Bad PHP "user experience" scenario (In use right now) a) User comes to site, clicks download button b) Users sees "download" landing page, gets redirected after 5 seconds c) Download starts on Thankyoupage Good "user experience" scenario: (my dream solution, what I want) a) User comes to site, clicks download button b) Download starts immediately on landing page c) Download confirmed, redirects now to thank you page Any programming language is a go for this.

• Which tips helped you learn touch-typing? [closed]

  - by julien

  I've been learning touch-typing for about two weeks now, and I'm really commited to mastering this skill. Eventhough I'm doing ok with prose already, I'm struggling with programming syntax and even more with keybindings. Those stray you away from the home row more than regular words, and aren't as easy to practice. So I often hunt and peck in order to just get it out, but when reverting to old habits like this, I find it hard to get back into the touch-typing mindframe quickly. One little trick that has helped me so far when getting lost is to reposition every finger on its home row key, and mentally visualize the layout bias of the keyboard, ie the backslash kind of alignment of key columns. It's hard to describe though and probably a bit weird... Hope you guys have better tips !

• Where to start learning OpenGL with C++?

  - by NERDcustard

  I'm 16 years old and my name is Norbert. I have learnt C++ and made some cool text based games and such but I would love to start graphic's programming. I'm a decent artiest (I will have some of my work bellow) I know the base of C++ but I really would like to get into OpenGL. I need someone to show me some good tutorials for OpenGl with C++ so I can really get into game dev. My goal is to be able to program a simple 2d game by the end of the year and I have lots of time to do so. I'm en-rolled in a game dev next year and really need some help with starting off. http://imgur.com/QZjKX http://imgur.com/3CZy7

• Why are so many questions closed? [closed]

  - by Kim Jong Woo

  Why is there so many questions on this stackexchange site closed? I mean far more than usual. Even very high quality discussions are closed. Doesn't this high number of closed questions with high number of views and good quality of content seem like that the current policy that governs the criteria for appropriate question might be going against nature? I mean it feels as if lot of questions or discussions are everything surrounding programmer, programming, and need not be objective or seeking definitive answer. It appears lot of questions are of inquisitive nature seeking insight into other programmers and finding common subjects of interest. Is it possible for mods to relax a bit? I mean lot of great questions with [closed] tag everywhere doesn't do justice. This question in itself is a perfect example of what I am talking about and it will be closed. But I think my point is clear.

• Using dot To Access Object Attribute and Proper abstraction

  - by cobie

  I have been programming in python and java for quite a number of years and one thing i find myself doing is using the setters and getters from java in python but a number of blogs seem to think using the dot notation for access is the pythonic way. What I would like to know is if using dot to access methods does not violate abstraction principle. If for example I implement an attribute as a single object and use dot notation to access, if I wanted to change the code later so that the attribute is represented by a list of objects, that would require quite some heavy lifting which violates abstraction principle.

• Why do game engines convert models to triangles compared to keeping it as four side polygon

  - by Grant

  I've worked using maya for animation and more film orientated projects however I am also focusing on my studies on video game development (eventually want to be either programmer or some sort of TD with programming and 3D skills). Anyways, I was talking with one of my professor and we couldn't figure out why all game engines (that I know of) convert to triangles. Anyone happen to know why game engines convert to triangles compared to leaving the models as four sided polygons? Also what are the pros and cons (if any) of doing this? Thanks in advance.

• Complete Guide/Tutorials on LWJGL?

  - by user43353

  Dont get me wrong, I finished these tutorials on http://lwjgl.org/wiki/index.php?title=Main_Page. I finished The Basics section, OpenGL 3.2 and newer section, and I looked at the Example Code section. They were great tutorials, and I have looked at the external tutorials as well. I don't know where to go from here, and OpenGL is not my strong point. Some one suggested Learning Modern 3D Graphics Programming, and I didnt learn much. I looked at the port to LWJGL, but the book was on C and I couldn't really understand what the OpenGL meant. I am trying to learn 2D gaming, not 3D. Maybe later. Is there any tutorials that aren't C/C++ heavy and teach you 2D OpenGL?

• Republishing blog posts on a popular website

  - by Giorgi

  I started my blog about programming yesterday and in order to promote and increase traffic I submitted my rss to Codeproject which pulls my posts and publishes them at Codeproject. While it increases the number of people reading my posts (but they are reading it at codeproject) I am worried that Google will penalize my site for duplicate content (Especially considering that Codeproject has much more reputation compared to my new website). The post at Codeproject has a link back to my blog post but it does not have "rel=canonical". So my question which one is better: a link from a high reputation website and some traffic or should I remove it from codeproject so that my blog is not penalized? What if codeproject adds "rel=canonical" to the link?

• Ubuntu on USB does not boot on MacBook

  - by Sean H

  Ubuntu is installed on a 32 gigabyte flash-drive and it successfully booted every time up until I partitioned my hard-drive and installed Windows as a secondary boot (for programming reasons). Now every time I attempt to boot the Ubuntu flash-drive it boots into Windows XP. The same goes for partitions, I partitioned my hard-drive and installed Ubuntu and it only booted Windows XP. I am on a MacBook 6,1 with Mac OS X 10.6.8, 2 partitions, and I am using ReFit as my boot-loader. EDIT: I had Ubuntu working fine from FLASH DRIVE and at one point as a partition. I later uninstalled Ubuntu from my hard-drive and installed Windows. I then had to re-image my computer for certain reasons and I installed windows. Now when I attempt to boot anything other than Windows or OS X it boots into windows. Ubuntu was never on my hard drive while Ubuntu was on it. The flash-drive has been its own thing and has the boot-loader installed to it and loads from ReFit but boots into windows.

• What skills does a web developer need to have/learn?

  - by Victor

  I've been I've asked around, and here's what I gathered so far in no particular order: Knowledge Web server management (IIS, Apache, etc.) Shell scripting Security (E.g. ethical hacking knowledge?) Regular Expression HTML and CSS HTTP Web programming language (PHP, Ruby, etc.) SQL (command based, not GUI, since most server environment uses terminal only) Javascript and library (jQuery) Versioning (SVN, Git) Unit and functional test Tools Build tools (Ant, NAnt, Maven) Debugging tools (Firebug, Fiddler) Mastering the above makes you a good web developer. Any comments?

• Studying computer science - what am I getting myself into?

  - by clankercrusher

  I'm a student considering the possibility of studying computer science. I've picked up programming indie games and websites as a hobby and I really enjoy it. Despite my fairly positive experience, I somehow get the feeling that computer science in the business world will be completely different than do-it-for-fun game making. Since I'm interested in the field and I'd like to study well, I want to prepare myself for the onslaught. (If that’s even possible) What are some of the most important principals I need to know if I decide to study computer science? What will I need to know about computer science that a University probably won't teach me? Is there any way I can get hands on experience before or while I'm at a University? What am I getting myself into? P.S. Is this the right stack exchange site for this type of question?

• Javascript naming conventions

  - by ManuPK

  I am from Java background and am new to JavaScript. I have noticed many JavaScript methods using single character parameter names, such as in the following example. doSomething(a,b,c) I don't like it, but a fellow JavaScript developer convinced me that this is done to reduce the file size, noting that JavaScript files have to be transferred to the browser. Then I found myself talking to another developer. He showed me the way that Firefox will truncate variable names to load the page faster. Is this a standard practice for web browsers? What are the best-practice naming conversions that should be followed when programming in JavaScript? Does identifier length matter, and if so, to what extent?

• Which numeral systems are useful in computer science?

  - by authchir

  I am wondering which numeral system different programmers are using, or would use if their language has support for them. As an example, in C++ we can use: Octal by prefixing with 0 (e.g. 0377) Decimal by default (e.g. 255) Hexadecimal by prefixing with 0x (e.g. 0xff) When working with bitmask, I am using hexadecimal but would sometimes want to be able to express binary numbers directly. I know some programming language support it with 0b syntax (e.g. 0b11111111). Is there any other numeric system useful in some computer science domain (e.g. cryptography, codecs, 3D graphics, etc)?

• Advice for transitioning into a Java developer position from doing other types of web development?

  - by Rick

  I've been doing web programming and currently work at a company working with mainly PHP and Javascript. For a little while now I've been becoming more and more frustrated with the shortcomings of this type of development and want to move to a company with a more defined development process that values doing things the "right way" such as using Unit tests, dependency injection / IoC, etc. I've been learning JEE / Java as much as I can on my own time but would really like to make a switch to doing this as my career and leave behind the PHP world altogether. I'm just wondering if anyone can give me advice on which things to put my main focus on right now to make myself marketable as an entry level Java developer. Basically, I feel that I'm not really learning anything new at my current job that will benefit me and its only making me more and more frustrated so I figure if there is any way to position myself for a transition I would rather do it sooner than later. Thanks for any advice.
