• Is ActionScript 3 used by Serious Indie Developers?

  - by Puedes

  This question is for dedicated independent game developers: My dream is to be a game developer. I am a senior in high school who has taken Computer Science for all four years. I have used Java the whole time, but last year I started using PHP and ActionScript 3 (with Flixel). I also used Game Maker for a brief period. I apologize for this, I wanted to get that out of the way and clarify the fact that I have experience of some kind with game development. I am stuck at the moment because I don't quite know what language to use to develop games at a professional level. I am seriously interested in becoming a dedicated game developer, but this issue is really bothering me. I would like to know what the best option would be for my case, based on your experiences. Any advice is appreciated. Things to consider: I am only interested in making 2D games (I am not worried about 3D support) It would be ideal to use something that can be ported to multiple platforms (so as not to run into this problem later) I can't seem to figure out what the industry likes to use So far, this is what I have: I can't decide if it would be wise to stick with ActionScript 3, or move to C++ I know Flash would be for browser games, but what if I want to make a downloadable game, like Plants Vs. Zombies or Super Crate Box? Would Flash be a smart choice for standalone games, or did they use something else? Thank you for reading this, as I would like to stop worrying about this and make some games! Also, I hope this wasn't all over the place :) tl;dr Should I move ahead with AS3 or use something else i.e. C++

• Edd strikes again &ndash; IronRuby for Rubyists on InfoQ

  - by Eric Nelson

  Colleague, friend and generally top guy on IronRuby Edd Morgan has just been published over on InfoQ. To wet the appetite… a snippet or three. IronRuby for Rubyists IronRuby is Microsoft's implementation of the Ruby language we all know and love with the added bonus of interoperability with the .NET framework — the Iron in the name is actually an acronym for 'Implementation running on .NET'. It's supported by the .NET Common Language Runtime as well as, albeit unofficially, the Mono project. You'd be forgiven for harbouring some question in your mind about running a dynamic language such as Ruby atop the CLR - that's where the DLR (Dynamic Language Runtime) comes in. The DLR is Microsoft's way of providing dynamic language capability on top of the CLR. Both IronRuby and the DLR are, as part of Microsoft's commitment to open source software, available as part of the Microsoft Public License on GitHub and CodePlex respectively… And Metaprogramming with IronRuby The art and science of metaprogramming — especially in Ruby, where it's an absolute joy — is something that could very easily span an entire article. As you would hope, IronRuby code is fully able to manipulate itself allowing you to bend your classes to your whim just as you would expect with a good dynamic language… And Riding the irails? So let's get to the point. I think it's a solid bet to make that a large proportion of Ruby programmers are familiar with the Rails framework - perhaps it's even safe to assume that most were first led to the Ruby language by the siren song of the Rails framework itself. Long story short, IronRuby is compatible enough to run your Rails app… Now… get yourself over to the full article and also check out some of Edds other work below.

• HTG Explains: What Are Computer Algorithms and How Do They Work?

  - by YatriTrivedi

    Unless you’re into math or programming, the word “algorithm” might be Greek to you, but it’s one of the building blocks of everything you’re using to read this article. Here’s a quick explanation of what they are, and how they work. Disclaimer: I’m not a math or computer science teacher, so not all of the terms I use are technical. That’s because I’m trying to explain everything in plain English for people aren’t quite comfortable with math. That being said, there is some math involved, and that’s unavoidable. Math geeks, feel free to correct or better explain in the comments, but please, keep it simple for the mathematically disinclined among us.

• What do I need to know to design a language and write a interpreter for it?

  - by alFReD NSH

  I know this question has been asked and even there are thousands of books and articles about it. But the problem is that there are too many, and I don't know are they good enough, I have to design a language and write a interpreter for it. The base language is javascript (using nodejs) but it's ok if the compiler was written in another language that I can use from node. I had done a research about compiler compilers in JS, there is jison (Bison implementaion in JS), waxeye, peg.js. I decided to give jison a try, due to the popularity and its being used by coffee script, so it should be able to cover my language too. The grammar definition syntax is similar to bison. But when I tried read the bison manual it seemed very hard to understand for me. And I think it's because I don't know a lot of things about what I'm doing. Like I don't what is formal language theory. I am experienced in Javascript (I'm more talented in JS than most average programmers). And also know basic C and C++ (not much experience but can write a working code for basic things). I haven't had any formal education, so I may not be familiar with some software engineering and computer science principles. Though everyday I try to grasp a lot of articles and improve. So I'm asking if you know any good book or article that can help me. Please also write why the resource you're suggesting is good. --update-- The language I'm trying to create, is not really complicated. All it has is expressions (with or without units), comparisons and logical operators. There are no functions, loops, ... The goal is to create a language that non-programmers can easily learn. And to write customized validations and calculations.

• Chrome Mobile Monthly: Responsive vs Separate Sites

  Chrome Mobile Monthly: Responsive vs Separate Sites Join us on Wednesday October 31st at 9am PT for our Monthly Mobile Web Hangout! This month +Brad Frost will be joining us to talk about responsive design versus separate mobile sites. And in keeping with the season, it's a special Presidential Smackdown Edition. The US presidential race is in full swing, and the candidates are intensely debating the country's hot-button issues. The web design world is entrenched in our own debate about how to address the mobile web: should we create a separate mobile site or create a responsive experience instead? It just so happens that the two US presidential candidates have chosen different mobile web strategies for their official websites. In the red corner is Republican candidate Mitt Romney's dedicated mobile site, while in the blue corner is incumbent president Barack Obama's responsive website. Which will prevail? Sit back, crack open a cold one, and watch the battle unfold as Brad dissect the candidates' sites to uncover best practices and common mobile web pitfalls.

• Do programmers need a union? [closed]

  - by James A. Rosen

  In light of the acrid responses to the intellectual property clause discussed in my previous question, I have to ask: why don't we have a programmers' union? There are many issues we face as employees, and we have very little ability to organize and negotiate. Could we band together with the writers', directors', or musicians' guilds, or are our needs unique? Has anyone ever tried to start one? If so, why did it fail? (Or, alternatively, why have I never heard of it, despite its success?) later: Keith has my idea basically right. I would also imagine the union being involved in many other topics, including: legal liability for others' use/misuse of our work, especially unintended uses evaluating the quality of computer science and software engineering higher education programs -- unlike many other engineering disciplines, we are not required to be certified on receiving our Bachelor's degrees evangelism and outreach -- especially to elementary school students certification -- not doing it, but working with the companies like ISC(2) and others to make certifications meaningful and useful continuing education -- similar to previous conferences -- maintain a go-to list of organizers and other resources our members can use I would see it less so as a traditional trade union, with little emphasis on: pay -- we tend to command fairly good salaries outsourcing and free trade -- most of use tend to be pretty free-market oriented working conditions -- we're the only industry with Aeron chairs being considered anything like "standard"

• Advancing my Embedded knowledge.....with a CS degree.

  - by Mercfh

  So I graduated last December with a B.S. in Computer Science, in a pretty good well known engineering college. However towards the end I realized that I actually like Assembly/Lower level C programming more than I actually enjoy higher level abstracted OO stuff. (Like I Programmed my own Device Drivers for USB stuff in Linux, stuff like that) But.....I mean we really didn't concentrate much on that in college, perhaps an EE/CE degree would've been better, but I knew the classes......and things weren't THAT much different. I've messed around with Atmel AVR's/Arduino stuff (Mostly robotics) and Linux Kernals/Device Drivers. but I really want to enhance my skills and maybe one day get a job doing embedded stuff. (I have a job now, it's An entry level software dev/tester job, it's a good job but not exactly what my passion lies in) (Im pretty good with C and certain ASM's for specific microcontrollers) Is this even possible with a CS degree? or am I screwed? (since technically my degree usually doesn't involve much embedded stuff) If Im NOT screwed then what should I be studying/learning? How would I even go about it........ I guess I could eventually say "Experienced with XXXX Microcontrollers/ASM/etc...." but still, it wouldn't be the same as having a CE/EE degree. Also....going back to college isn't an option. just fyi. edit: Any book recommendations for "getting used to this stuff" I have ARM System-on-Chip Architecture (2nd edition) it's good.....for ARM stuff lol

• Inspiring the method of teaching. Example- C++ :)

  - by Ashwin

  A year ago I graduated with a degree in Computer Science and Engineering. Considering C++ as the first choice of programming language I have been in the process of learning C++ in many ways. At first - five years back - I had many conceptions, most of which were so abstract to me. It started when I knew almost everything about Structs in C and nothing about Classes in C++. I went through a great time experimenting them all and learning a lot. I had a hard time evaluating Procedural programming vs Object-Oriented Programming. Deciding when to choose Procedural or Object-Oriented Programming took a great deal of patience for me. I knew that I cannot underestimate any of these Programming styles... Though Procedural programming is often a better choice than simple sequential unstructured programming, when solving problems with procedural programming, we usually divide one problem into several steps in order regarded as functions. Then we call these functions one by one to get the result of the problem. When solving problems with Object Oriented Priciples we divide one problem into several classes and form the interaction between them. Evaluating these two at the beginning (as a learner) required a lot of inspiration and thoughts. Instructing to think step by step. Relative concepts to understand deeply. Intensive interests to contrast both solving in both POP and OOP. If you were ever a mentor: What ideas/methods would you teach to students in which it will Inspire them to learn a programming language (in general, computer sciences)?

• Scheme vs Haskell for an Introduction to Functional Programming?

  - by haziz

  I am comfortable with programming in C and C#, and will explore C++ in the future. I may be interested in exploring functional programming as a different programming paradigm. I am doing this for fun, my job does not involve computer programming, and am somewhat inspired by the use of functional programming, taught fairly early, in computer science courses in college. Lambda calculus is certainly beyond my mathematical abilities, but I think I can handle functional programming. Which of Haskell or Scheme would serve as a good intro to functional programming? I use emacs as my text editor and would like to be able to configure it more easily in the future which would entail learning Emacs Lisp. My understanding, however, is that Emacs Lisp is fairly different from Scheme and is also more procedural as opposed to functional. I would likely be using "The Little Schemer" book, which I have already bought, if I pursue Scheme (seems to me a little weird from my limited leafing through it). Or would use the "Learn You a Haskell for Great Good" if I pursue Haskell. I would also watch the Intro to Haskell videos by Dr Erik Meijer on Channel 9. Any suggestions, feedback or input appreciated. Thanks. P.S. BTW I also have access to F# since I have Visual Studio 2010 which I use for C# development, but I don't think that should be my main criteria for selecting a language.

• I don't understand the definition of side effects

  - by Chris Okyen

  I don't understand the wikipedia article on Side Effects: In computer science, a function or expression is said to have a side effect if, in addition to returning a value, it also 1.) Modifies some state or 2.) Has an observable interaction with calling functions or the outside world. I know an example of the first thing that causes a function or expression to have side effects - modifying a state Function and Expression modifying a state : 1.) foo(int X) { return x = x % x; } a = a + 1; What does 2.) - Has an observable interaction with calling functions or the outside world," mean? - Please give an example. The article continues on to say, "For example, a function might modify a global or static variable, modify one of its arguments, raise an exception, write data to a display or file, read data, or call other side-effecting functions...." Are all these examples, examples of 1.) - Modifiying some state , or are they also part of 2.) - Has an observable interaction with calling functions or the outside world?

• What are `Developmental Milestones` for programming skills?

  - by Holmes

  I studied in the field of Computer Science for 6 years, bachelor's degree and master's degree. I have studied all the basic programming like C, Java, VB, C#, Python, and etc. When I have free times, I will learn new programming languages and follow new programming trends by myself , such as PHP, HTML5, CSS5, LESS, Bootstrap, Symfony2, and GitHub. So, if someone wants me to write some instructions using these languages, I'm certain that I can do it, not so good but I can get a job done. However, I don't have any favorite programming language. Moreover, I also have studied about algorithms, database, and etc. Everything I just wrote so far seems that I know a lot in this field. In fact, I feel I am very stupid. I cannot answer 80% of the questions on SO. In spite of those languages??, I have studied. Perhaps it is because I have never worked before. As there is the Developmental Milestones for children, which refers to how a child becomes able to do more complex things as they get older, I would like to evaluate the same thing but for programming skills. What are the set of functional skills or age-specific tasks that most programmers can do at a certain age range? In order to evaluate myself, I would like to ask your opinions that all of the skills I mentioned above, are they enough for programmers to know when they are 25 years old? What are your suggestions in order to improve the skills in this field?

• Why CFOs Should Care About Big Data

  - by jmorourke

  The topic of “big data” clearly has reached a tipping point in 2012.  With plenty of coverage over the past few years in the IT press, we are now starting to see the topic of “big data” covered in mainstream business press, including a cover story in the October 2012 issue of the Harvard Business Review.  To help customers understand the challenges of managing “big data” as well as the opportunities that can be created by leveraging “big data”, Oracle has recently run and published the results of a customer survey, as well as white papers and articles on this topic.  Most recently, we commissioned a white paper titled “Mastering Big Data: CFO Strategies to Transform Insight into Opportunity”. The premise here is that “big data” is not just a topic that CIOs should pay attention to, but one that CFOs should understand and take advantage of as well.  Clearly, whoever masters the art and science of big data will be positioned for competitive advantage in their industries or markets.  That’s why smart CFOs are taking control of big data and business analytics projects, not just to uncover new ways to drive growth in a slowing global economy, but also to be a catalyst for change in the enterprise.  With an increasing number of CFOs now responsible for overseeing IT investments and providing strategic insight to the board, CFOs will be increasingly called upon to take a leadership role in assessing the value of “big data” initiatives, building on their traditional skills in reporting and helping managers analyze data to support decision making. Here’s a link to the white paper referenced above, which is posted on the Oracle C-Central/CFO web site, as well as some other resources that can help CFOs master the topic of “big data”: White Paper “Mastering Big Data:  CFO Strategies to Transform Insight into Opportunity CFO Market Watch article:  “Does Big Data Affect the CFO?” Oracle Survey Report:  “From Overload to Impact – An Industry Scorecard on Big Data Industry Challenges” Upcoming Big Data Webcast with Andrew McAfee Here’s a general link to Oracle C-Central/CFO in case you want to start there: www.oracle.com/c-central/cfo Feel free to contact me if you have any questions or need additional information:  [email protected]

• Using Mercurial repository inside a Git one: Feasible? Sane?

  - by Portablejim

  I am thinking on creating a Mercurial repository under a Git repository. e.g. ..../git-repository/directory/hg-repo/ The 2 repositories Is it possible to manage (keeping your sanity)? How similiar is it to this? I am a computer science student at University. I manage my work in Git, mainly as a distribution mechanism (after realizing that rsync fails when you have changes in more than one place) between my desktop and usb drive. I try use of Git as a VCS as I do work. I have finished a semester where I did a small group project to prepare for a larger group project next year. We had to use Subversion, and experienced the joys of a centralised VCS (including downtime). I tried to keep the subversion repository separate to my Git repository for the subject**, however it was annoying that it was seperate (not in the place where I store assignments). I therefore moved to using an Subversion repository inside my Git repository. As I think ahead (maybe I am thinking too far ahead) I realise that I will have to try and convince people to use a DVCS and Mercurial will probably be the one that is preferred (Windows and Mac GUI support, closer to Subversion). Having done some research into the whole Git vs Mercurial debate (however not used Mercurial at all) I still prefer Git. Can I have a Mercurial repository inside a Git one without going mad (or it ruining something)? Or is it something that I should not consider at all? (Or is it a bad question that should be deleted?) ** I think outside of Australia it is called a course

• Working Abroad Advice Needed

  - by RBA

  Hi, First of all, Happy New Year everybody! I wish you for 2011 all the best! For several years I was thinking about to work abroad, and I want to make this step(to work in a/several foreign countries, for several years). I am a Software Developer with a Bachelor of Engineering in Computer Science, with a +4 years of experience in Delphi(and small working experience in other programming languages). Until now I've applied at aprox. 100 positions over the world, and I've been contacted by 4-5 hiring managers. Our technical discussions went good, but then we reached at working visa 'problem'. I don't have legal/health problems, but I don't poses a working permit in other countries except Romania. I've been reading several forums concerning the working visas (here I take out working visa for US or other 'hard to get visa' countries), and there are several steps which companies must do (so I can take out the bureaucracy problem) to make the papers. Concerning the cost of a visa, this goes up to one medium salary from that country(in most of the cases). I've been working for the last years with different clients, from a wide variety of countries, and I don't believe I will have problems with integration in a foreign country So, the problem is that the market don't need Delphi Developers (there is a small amount of open positions on the recruiting sites), and I should start learning other programming language(all the time is better to know other programming languages - but to master it, requires some time) with a higher market 'rank' (Java/C#/etc), OR the problem is only concerning the working visa, and maybe the reticence of the employer to foreign possible candidates? I'm asking this especially for those users who made this step in their life or they want to make it in the future. Best regards,

• Was API hooking done as needed for Stuxnet to work? I don't think so

  - by The Kaykay

  Caveat: I am a political science student and I have tried my level best to understand the technicalities; if I still sound naive please overlook that. In the Symantec report on Stuxnet, the authors say that once the worm infects the 32-bit Windows computer which has a WINCC setup on it, Stuxnet does many things and that it specifically hooks the function CreateFileA(). This function is the route which the worm uses to actually infect the .s7p project files that are used to program the PLCs. ie when the PLC programmer opens a file with .s7p the control transfers to the hooked function CreateFileA_hook() instead of CreateFileA(). Once Stuxnet gains the control it covertly inserts code blocks into the PLC without the programmers knowledge and hides it from his view. However, it should be noted that there is also one more function called CreateFileW() which does the same task as CreateFileA() but both work on different character sets. CreateFileA works with ASCII character set and CreateFileW works with wide characters or Unicode character set. Farsi (the language of the Iranians) is a language that needs unicode character set and not ASCII Characters. I'm assuming that the developers of any famous commercial software (for ex. WinCC) that will be sold in many countries will take 'Localization' and/or 'Internationalization' into consideration while it is being developed in order to make the product fail-safe ie. the software developers would use UNICODE while compiling their code and not just 'ASCII'. Thus, I think that CreateFileW() would have been invoked on a WINCC system in Iran instead of CreateFileA(). Do you agree? My question is: If Stuxnet has hooked only the function CreateFileA() then based on the above assumption there is a significant chance that it did not work at all? I think my doubt will get clarified if: my assumption is proved wrong, or the Symantec report is proved incorrect. Please help me clarify this doubt. Note: I had posted this question on the general stackexchange website and did not get appropriate responses that I was looking for so I'm posting it here.

• Java Applet Tower Defence Game needs tweeking

  - by Ephiras

  Hello :) i have made a tower defence Game for my computer science class as one of my major projects, but have encountered some rather fatal roadblocks. here they are creating a menu screen (class Menu) that can set the total number of enimies, the max number of towers, starting money and the map. i tried creating a constructor in my Main class that sets all the values to whatever the Menu class passes in. I want the Menu screen to close after a difficulty has been selected and the main class to begin. Another problem i would really like some help with is instead of having to write entire arrays i would like to create a small segment of code that runs through an entire picture and sets up an array based on that pixels color.this way i can have multiple levels just dragged into a level folder and have the program read through them. users can even create their own. so a 1 if its yellow, a two if blue and a 3 if purple, then everything else = 0; you can download all the classes and code uif you'd like here sorry about having to redirect you but i wasn't sure how to efficently add a code spoiler. help is greatly appreciated

• Stacks in C++

  - by MarkPearl

  So some more basics… One of the things you will be taught at any college after conquering arrays is different derivatives of collections. Stack is one of the simplest of those and very useful… A stack is a LIFO (last in first out) data structure and has at least two basic method calls – push & pop. Push, “pushes” an item on the top of the stack. Pop, removes the top most item off the stack. Because all elements on a stack are of the same type, one can use an array to implement a stack or a linked list. With the array based approach, the first element in a stack would be the first element in the array, the second on the stack would be the second on the array, etc. One limitation with an array implementation of a stack is that unless the array is dynamic, one would have to have a preset max stack size (based on the bounds of the array). Linked lists is another approach that gets past this boundary by allowing you to dynamically grow or shrink a collection of data. Stacks have many applications… a typical computer science example would be Postfix Expression Calculator, where the LIFO principle is maintained.

• How do references work in R?

  - by djechlin

  I'm finding R confusing because it has such a different notion of reference than I am used to in languages like C, Java, Javascript... Ruby, Python, C++, well, pretty much any language I have ever programmed in ever. So one thing I've noticed is variable names are not irrelevant when passing them to something else. The reference can be part of the data. e.g. per this tutorial a <- factor(c("A","A","B","A","B","B","C","A","C")) results <- table(a) Leads to $a showing up as an attribute as $dimnames$a. We've also witnessed that calling a function like a <- foo(alpha=1, beta=2) can create attributes in a of names alpha and beta, or it can assign or otherwise compute on 1 and 2 to properties already existing. (Not that there's a computer science distinction here - it just doesn't really happen in something like Javascript, unless you want to emulate it by passing in the object and use key=value there.) Functions like names(...) return lvalues that will affect the input of them. And the one that most got me is this. x <- c(3, 5, 1, 10, 12, 6) y = x[x <= 5] x[y] <- 0 is different from x <- c(3, 5, 1, 10, 12, 6) x[x <= 5] <- 0 Color me confused. Is there a consistent theory for what's going on here?

• How can I make myself better at programming working at a shi* job ?

  - by Scrooge

  I recently graduated with an Engineering degree in Computer Science, but my employer (a mid-sized software company) is not using my logical and programming skills. I want to move to a better opportunity but how do I do that since my experience here is not going to count as much? How do I get a better programming job? The worst part is that I am still reading from books (and not writing code myself) even after I have started working. They are paying me a standard entry level Indian IT job rate but I really dont care. It's not worth it. Please advise as to how I can do something worthwhile. (I have studied C++; Core Java; Ruby On Rails ..made a couple of academic projects but no relevant practical real world experience). Just to make things easier .. let me list a few basic queries How I get better at programming without a good project at my company? Please suggest projects where I can learn to write practical code (platform doesn't matter) Best place to take part in open source development? Is it possible that I earn slightly more while I learn? (apart from my sh** job I mean) What kind of practical projects are best suited for me? (ie for an entry level programmer)

• Oracle Fusion Applications Design Patterns Now Available For Developers

  - by ultan o'broin

  The Oracle Fusion Applications user experience design patterns are published! These new, reusable usability solutions and best-practices, which will join the Oracle dashboard patterns and guidelines that are already available online, are used by Oracle to artfully bring to life a new standard in the user experience, or UX, of enterprise applications. Now, the Oracle applications development community can benefit from the science behind the Oracle Fusion Applications user experience, too. The design patterns are based on Oracle ADF components and easily implemented in Oracle JDeveloper. These Oracle Fusion Applications UX Design Patterns, or blueprints, enable Oracle applications developers and system implementers everywhere to leverage professional usability insight when: tailoring an Oracle Fusion application, creating coexistence solutions that existing users will be delighted with, thus enabling graceful user transitions to Oracle Fusion Applications down the road, or designing exciting, new, highly usable applications in the cloud or on-premise. Based on the Oracle Application Development Framework (ADF) components, the Oracle Fusion Applications patterns and guidelines are proven with real users and in the Applications UX usability labs, so you can get right to work coding productivity-enhancing designs that provide an advantage for your entire business. What’s the best way to get started? We’ve made that easy, too. The Design Filter Tool (DeFT) selects the best pattern for your user type and task. Simply adapt your selection for your own task flow and content, and you’re on your way to a really great applications user experience. More Oracle applications design patterns and training are coming your way in the future. To provide feedback on the sets that are currently available, let me know in the comments!.
