• Zune API Library for Ruby

  - by kerry

  Those of you who know me, know my favorite music player is the Zune. For some reason it seems most of my spare time lately seems to be creating Zune API libraries for different languages (I have a PHP one as well).  Here’s another one for Ruby!  If you use it, let me know.  I would love to hear what people are working on. It’s hosted at github, and very easy to use. zune_card = Zune::ZuneCard.for('a_zune_tag') Checkout the README for deets on what fields the object will have.

  - by helle

  can anybody recommend (of developers-opinion) such systems, where you can book tickets for concerts, conferences, etc. one should be able to book a seat as well, and it shell do the debitcard stuff, and has a good interface for accounting. I am looking for an open source solution, but I am also interested in commercial ones, to have a comparison of features and prices, etc. thanks for everybodys suggestions - pros and cons to it are very wellcome ;) well, it shouldn't has a flash component multi languages :) would be great an extra mobile-view is preferred the extra extra bonus for such a system would be a very good wordpress compatibility p.s. sorry for my english well ... I already googled a lot. But I found so very many, that I hope you could help me to find a good choice, to have a base from where I can do a further lookup. and for sure :) What are the things you I have to have in mind. What brings troubles, what brings costs?

• Maker Faire 2012 Attendees build with Java Technology

  - by hinkmond

  Looks like Daniel Green, systems engineer from Oracle, and the panel of Java experts had a successful Java Technology booth at this year's Maker Faire 2012. See: Maker Faire 2012 adds Java Here's a quote: "We made a huge impact for Java and Oracle, creating positive perception, building brand awareness, and introducing fun and engaging ways for future technologists to learn Java programming," says Michelle Kovac, Oracle director, Java Marketing and Operations. Good stuff, considering all the future developers of exploding robots and fire-breathing dragon metal sculptures attend the Maker Faire. They can blow up stuff with Java technology just as effectively as other programming languages. Hinkmond

• Development on Terminal or IDE [on hold]

  - by Taylor Flores

  I've been using nano, make, gcc, and gdb for 6 months now and I've found it much easier than using VS or Codeblocks. But I'm wondering now: Is development on a terminal more/less efficient that using an IDE? In what situations is one preferred more sensible than the other? I'm not asking about opinions, I want to know if there's specific reasons to use one over the other. From what I can gather: terminals can be used on environments where a GUI is not available terminal projects can be created and configured more quickly IDEs contain better syntax highlighters (ie identity highlighters) This question is C biased, but I think it's relevant to other languages as well.

• Recommended certification to join in a game development internship [on hold]

  - by Conrado Costa

  I'm Brazilian and I'll go to California in July 2014 to study for 1 year and I'm intending to get a winter internship in the game development industry. I'm a programmer since 2008 and I know C#, PHP, Java, Python and a bit of Perl. My question is: do you know any certified required (or helpful) to get a winter job as a game developer? I have no problem to learn new languages, I'm thinking to get a C or C++ certified because I'm not sure about which is the most used language, but before to start a study marathon to take a certification, I have to choose the language and the certification itself. Can you help me, and is that a valid question?

• Immutable Method Java

  - by Chris Okyen

  In Java, there is the final keyword in lieu of the const keyword in c and c++. In the latter languages their is mutable and immutable methods such as stated in one answer by Johannes Schaub - litb the question how-many-and-which-are-the-uses-of-const-in-ce Use const to tell others methods won't change the logical state of this object. struct SmartPtr { int getCopies() const { return mCopiesMade; } }ptr1; ... int var = ptr.getCopies(); // returns mCopiesMade and is specified that to not modify objects state. How is this performed in Java?

• Is there a good book to grok C++?

  - by Paperflyer

  This question got me thinking. I would say I am a pretty experienced C++ programmer. I use it a lot at work, I had some courses on it at the university, I can understand most C++ code I find out there without problems. Other languages you can pretty much learn by using them. But every time I use a new C++ library or check out some new C++ code by someone I did not know before, I discover a new set of idioms C++ has to offer. Basically, this has lead me to believe that there is a lot of stuff in C++ that might be worth knowing but that is not easily discoverable. So, is there a good book for a somewhat experienced C++ programmer to step up the game? You know, to kind of 'get' that language the way you can 'get' Ruby or Objective-C, where everything just suddenly makes sense and you start instinctively knowing 'that C++ way of thing'?

• Detailed C++ book for a programmer already familiar with C and object-oriented programming?

  - by Anto

  I know (to some extent) a few languages, including C, Java and Python. I'm also (somewhat) familiar with Scala and Scheme, plus I can read (but not write) x86 Assembly. Say I want to learn C++, what is a good book which doesn't try to teach me what a class is, teach me inheritance, polymorphism or loosely coupled classes again, nor does try to teach me other basics, just the C++ language (as well as how to write idiomatic C++ code, not e.g. Java with C++ syntax) and its standard library? Note: "Detailed" as used in the title means that it doesn't try to cover C++ in 100 pages, I want to know the details of the language. Of course, mastery comes from practice, but I don't want to learn just a little bit of C++ from the book, but learn it quite thoroughly.

• Beyond Syntax Highlighting - What other code representations are possible today?

  - by Mathieu Hélie

  Despite GUI applications having been around for 30ish years, software is still written as lines of text instructions, for various valid reasons. But we've also found that manipulating these text instructions is mind-blowingly difficult unless we apply a layer of coloring on different words to represent their syntax, thus allowing us to quickly parse through these text files without having to read the whole words. But besides the Sublime Text minimap feature, I've yet to see any innovation in visual representation of code since colors came around on CRT monitors. I can think of one obviously essential representation that modern graphics technology allows: visual hierarchies for nested structures. If we make nested text slightly smaller than its outer context, and zoom on it when the cursor is focused on the line, then we will be able to browse huge files of nested statements very quickly. This becomes even more essential as languages based on closures and anonymous functions become filled with deep statements. Has anyone attempted to implement this in a text editor? Do you know of any otherwise useful improvements in representing code text graphically?

• The perfect crossfade

  - by epologee

  I find it hard to describe this problem in words, which is why I made a video (45 seconds) to illustrate it. Here's a preview of the questions, please have a look at it on Vimeo: http://vimeo.com/epologee/perfect-crossfade The issue of creating a flawless crossfade or dissolve of two images or shapes has been recurring to me in a number of fields over the last decade. First in video editing, then in Flash animation and now in iOS programming. When you start googling it, there are many workarounds to be found, but I really want to solve this without a hack this time. The summary: What is the name of the technique or curve to apply in crossfading two semi-transparent, same-colored bitmaps, if you want the resulting transparency to match the original of either one? Is there a (mathematical) function to calculate the neccessary partial transparency/alpha values during the fade? Are there programming languages that have these functions as a preset, similar to the ease in, ease out or ease in out functions found in ActionScript or Cocoa?

• Where can I get feedback and support from other programmers in real time?

  - by cypherblue

  I used to work in an office surrounded by a large team of programmers where we all used the same languages and had different expertises. Now that I am on my own forming a startup at home, my productivity is suffering because I miss having people I can talk to for specific help, inspiration and reality checks when working on a coding problem. I don't have access to business incubators or shared (co-working) office spaces for startups so I need to chat with people virtually. Where can I go for real-time chat with other programmers and developers (currently I'm looking for people developing for the web, javascript and python) for live debugging and problem-solving of the tasks I am working on? And what other resources can I use to get fellow programmer support?

• Paying a developer in stock/fixed rate? [closed]

  - by user51648

  I have an idea for a cross platform application. It will require knowledge of several different languages, web development, and system administration/IT. I don't personally code, but I want to pay professionals to do it. I'm wondering how I should go about paying them. Yes, this will be a large project, but I want it done ASAP. Is it ok if I don't pay them by the hour? I really want it to be a set price. Also, is it reasonable to pay them in stock of the company? Like, 20%? P.S. How do I know how big a project will be in order to give the devs themselves an idea?

• CS Concentrations and Career Paths

  - by xbonez

  I'm approaching the end of Sophomore year in college (Studying Computer Science), and very soon I'm going to have to decide on my concentration, but I honestly don't know what each concentration means. I basically have two questions: 1. How much influence does your concentration have on your career path? For example, would a video game development company only look at people with a concentration in Game Development? 2.It would be great if you guys could, in a line or two, tell me what sort of jobs am I looking at for each of the concentrations? I need to pick at least two of the 9 below. - Algorithms and Data Structures - Artificial Intelligence - Computer and Network Society - Computer graphics and vision - Human-Computer Interaction - Game Development and Design - Numeric and Symbolic Computation - Programming languages - Systems

• Is true multithreading really necessary?

  - by Jonathan Graef

  So yeah, I'm creating a programming language. And the language allows multiple threads. But, all threads are synchronized with a global interpreter lock, which means only one thread is allowed to execute at a time. The only way to get the threads to switch off is to explicitly tell the current thread to wait, which allows another thread to execute. Parallel processing is of course possible by spawning multiple processes, but the variables and objects in one process cannot be accessed from another. However the language does have a fairly efficient IPC interface for communicating between processes. My question is: Would there ever be a reason to have multiple, unsynchronized threads within a single process (thus circumventing the GIL)? Why not just put thread.wait() statements in key positions in the program logic (presuming thread.wait() isn't a CPU hog, of course)? I understand that certain other languages that use a GIL have processor scheduling issues (cough Python), but they have all been resolved.

• How important is Discrete Mathematics for a Computer Scientist?

  - by mort

  As the title says, How important is Discrete Mathematics for a Computer Scientist? Background: I'm pursuing a Master's degree with a focus on fundamentals such as Algorithms, Complexity and Computability Theory and Programming Languages to get a good foundation for working in the field of Parallel Computing. Some more background: My university grants a lot of freedom in the choices of courses for my Master's degree. It's officially called "Software Engineering", but due to a the broad range of electives, a different focus is possible. Interestingly, none of the electives is a lecture in Math! I'm thinking about doing a course about Discrete Mathematics that would take half a semester to complete successfully, even if I can't use it for my degree. So with this question I'm trying to find out if the effort is justifiable.

• Functional programming readability

  - by Jimmy Hoffa

  I'm curious about this because I recall before learning any functional languages, I thought them all horribly, awfully, terribly unreadable. Now that I know Haskell and f#, I find it takes a little longer to read less code, but that little code does far more than an equivalent amount would in an imperative language, so it feels like a net gain and I'm not extremely practiced in functional. Here's my question, I constantly hear from OOP folks that functional style is terribly unreadable. I'm curious if this is the case and I'm deluding myself, or if they took the time to learn a functional language, the whole style would no longer be more unreadable than OOP? Has anybody seen any evidence or got any anecdotes where they saw this go one way or another with frequency enough to possibly say? If writing functionally really is of lower readability than I don't want to keep using it, but I really don't know if that's the case or not..

• Low "time on site" and high bounce-rate in Japan

  - by Noam

  I'm seeing a substantially low "time on site" and high bounce rate from visitors coming from Japan. Comparing to other states, even in languages I don't speak, the stats are still dramatically worse. So I assume there's something specific to that nation, that I should understand in order to make their experience better. The content they are seeing is in Japanese, and I've also translated the head-lines, which to my surprise didn't make stats look better. The site doesn't have a mobile version, so I assume that might be part of the problem. Wanted to hear from your experience what other reasons might there be that are specific for Japan. UPDATE: The content itself was in Japanese all the time, that's the reason it attracts users from Japan. The head-lines were in English, so I only changed them.

• What is missing and should be added to Code Complete 3rd Edition? [closed]

  - by Peter Turner

  It's been quite a few years since Code Complete was published. I really love the book, I keep it in the bathroom at the office and read a little out of it once or twice a day. What developments in computer software... development need to be added to Code Complete 3e, and for the sake of reductionism, what should be removed to make room for them? Is it necessary even possible to call Code Complete Code Complete if it doesn't have language features that even Delphi has like anonymous methods and generics? Also, what languages would be more appropriate than C++ to use for a majority of code examples?

• What are the pro/cons of Unity3D as a choice to make games ?

  - by jokoon

  We are doing our school project with Unity3d, since they were using Shiva the previous year (which seems horrible to me), and I wanted to know your point of view for this tool. Pros: multi platform, I even heard Google is going to implement it in Chrome everything you need is here scripting languages makes it a good choice for people who are not programming gurus Cons: multiplayer ? proprietary, you are totally dependent of unity and its limit and can't extend it it's less "making a game from scratch" C++ would have been a cool thing I really think this kind of tool is interesting, but is it worth it to use at school for a project that involves more than 3 programming persons ? What do we really learn in term of programming from using this kind of tool (I'm ok with python and js, but I hate C#) ? We could have use Ogre instead, even if we were learning direct x starting january...

• Future-proofing myself when learning to program.

  - by Chris Bridgett

  I want to learn to program in a 'future-proof' manner, if you like. Whilst Windows dominates the desktop OS marketplace (for now), obviously there is a lot of value in learning its languages/frameworks/API's and so on - this might be subject to change as new devices emerge or Windows shoots itself in the foot (over-friendly previews of Windows 8 don't look too appealing...). Would I be right in thinking that having a solid knowledge of C/C++ for back-end logic/low level programming and the like, combined with an extremely portable language like Java for GUI's and so on, would be a good basis for software development that will prove useful on the most amount of systems? - I'm talking desktop PC's, tablets, phones.
