• Incorporating libs into module pattern

  - by webnesto

  I have recently started using require.js (along with Backbone.js, jQuery, and a handful of other JavaScript libs) and I love the module pattern (here's a nice synopsis if you're unfamiliar: http://www.adequatelygood.com/2010/3/JavaScript-Module-Pattern-In-Depth). Something I'm running up against is best practices on incorporating libs that don't (out of the box) support the module pattern. For example, jQuery without modification is going to load into a global jQuery variable and that's that. Require.js recognizes this and provides an example project for download with a (slightly) modified version of jQuery to incorporate with a require.js project. This goes against everything I've ever learned about using external libs - never modify the source. I can list a ton of reasons. Regardless, this is not an approach I'm comfortable with. I have been using a mixed approach - wherein I build/load the "traditional" JS libraries in a "traditional" way (available in the global namespace) and then using the module pattern for all of my application code. This seems okay to me, but it bugs me because one of the real beauties of the module pattern (no globals) is getting perverted. Anyone else got a better solution to this problem?

• Languages on a resume: Is it better to put "C/C++" or "C, C++"?

  - by Kevin

  I'm graduating in a couple of weeks, and my resume (as expected) lists the languages that I've had experience with. Previously I've put "C/C++", however back then I didn't have that much experience with these two languages as I do now. Now that I've formally learned these two languages, it has become evident to me (and anyone who really knows these languages) that they are similar, and completely disimilar at the same time. Sure, most C code is compilable C++ code, but syntax and incorporation of library functions is pretty much where these similarities end. In most non-trivial problems, chances are that the desirable C++ solution will be different from the desirable C solution. My question: Will recruiters take note or care about whether you put "C/C++" as opposed to "C, C++"? Will they assume a lack of knowledge of the workings of either because of the inclusion of the first form, or perhaps see the inclusion of the second form as a potential "resume beefer" (listing them as 2 languages, instead of "one")? Furthermore, for jobs that you've applied to that were particularly interested in these two langauges, did the interview process include questions about the differences between C programming and C++ programming (so, about actual programming techniques, not only the extra paradigms in the latter)?

• CLR and C# Learning Materials

  - by Gerry O'Brien

  Have you ever found that one book or resource that just brings it all home?  Seriously.  These are rare finds when you read the content and all the stars seem to align, you have those "Ah ha!" moments. Well, I have found that book and it is CLR via C#, Third Edition by Jeffrey Richter.  If you're not familiar with Wintellect, look them up.  This book is published by Microsoft Press and is the third edition of this title.  I'm in chapter 5 at the moment and already I have a better understanding of the CLR and how things work.  I'm a former Visual Basic MVP and C# is a language I learned as a result of projects I worked on at a software development company a few years ago.  Like a lot of VB programmers, I never went deep into the workings of the "behind the scenes" aspects and just focused on the applications. My next possible career move involves a deeper knowledge of the CLR and a .NET language.  This book is one that I will have my bookshelf for reference long after I have read that last page. Gerry

• A short but intense GCC Gathering in London

  - by user817571

  About one week ago I joined in London many long time GCC friends and acquaintances for a gathering organized by Google (in particular I guess should be thanked Diego and Ian). Only a weekend, and I wasn't able to attend on Sunday morning, but a very good occasion to raise some issues in a very relaxed way, in particular those at the border between areas of competence, which are the most difficult to discuss during the normal work days. If you are interested in a general overview and some notes this is a good link: http://gcc.gnu.org/wiki/GCCGathering2011 As you may easily guess, the third topic is mine, which I managed to have up quite early on Friday morning thanks to the votes of some good friends like Dodji (the ordering of the topics resulted from democratic voting on Friday evening!). I learned a lot from the discussion: for example that certainly the new C++11 'final' should be exploited largely in the c++ front-end; the various reasons why devirtualization can be quite trick (but I'm really confident that Martin and Honza are going to make a good progress also basing on a set of short testcases which I promised to collect); that, as explained by Ian, the gold linker already implements the nice --icf (Identical Code Folding) facility, which some friends of mine are definitely going to like (however, see: http://sourceware.org/bugzilla/show_bug.cgi?id=12919). I also enjoyed the observations made by Lawrence, where he remarked that in C+11 we are going to see more pointer iterations implicitly produced by the new range-based for-loop and we really want to make sure the loop optimizers are able to deal with those as well as loops explicitly using a counter. All in all, I really hope we are going to do it again!

• Android: how do I switch between game scenes in a game? Any tutorials?

  - by Flavio

  I am trying to create a simple game using the Android SDK without using AndEngine (or any other game engine). I have plenty of experience designing games from the past, but I'm having lots of trouble trying to use the Android SDK to make my game. By far my biggest hurdle right now is switching between views. That is, for example, going from the menu to the first level, etc. I am using a traditional model I learned (I think it's called a scene stack or something?) in which you push the current scene onto a stack and the game's main loop runs the top item of the stack. This model seems non-trivial to implement in the Android SDK, mostly because Android seems to be picky about which thread instantiates which view. My issue is that I want the first level to show up when you press a button on the main menu, but when I instantiate the first level (the level class extends SurfaceView and implements SurfaceHolder.Callback) I get a runtime error complaining that the thread that runs the main menu can't instantiate this class. Something about calling Looper.prepare(). I figured at this point I was probably doing things wrong. I'm not sure how to specifically phrase my issue into a question, so maybe I should leave it as either 1) Does anybody know a good way (or the 'proper' way) to switch between scenes in an Android game? or 2) Are there any tutorials out there which show how to create a game that doesn't take place entirely in one scene? (I have googled for a while to no avail... maybe someone else knows of one?) Thanks!

• Happy Tau Day! (Or: How Some Mathematicians Think We Should Retire Pi) [Video]

  - by Jason Fitzpatrick

  When you were in school you learned all about Pi and its relationship to circles and turn-based geometry. Some mathematicians are rallying for a new lesson, on about Tau. Michael Hartl is a mathematician on a mission, a mission to get people away from using Pi and to start using Tau. His manifesto opens: Welcome to The Tau Manifesto. This manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant relating the circumference of a circle to its linear dimension. For millennia, the circle has been considered the most perfect of shapes, and the circle constant captures the geometry of the circle in a single number. Of course, the traditional choice of circle constant is p—but, as mathematician Bob Palais notes in his delightful article “p Is Wrong!”,1 p is wrong. It’s time to set things right. Why is Pi wrong? Among the arguments is that Tau is the ration of a circumference to the radius of a circle and defining circles by their radius is more natural and that Pi is a 2-factor number but with Tau everything is based of a single unit–three quarters of a turn around a Tau-defined circle is simply three quarters of a Tau radian. Watch the video above to see the Tau sequence (which begins 6.2831853071…) turned into a musical composition. For more information about Tau hit up the link below to read the manifesto.

• Java Champion Dick Wall Explores the Virtues of Scala (otn interview)

  - by Janice J. Heiss

  In a new interview up on otn/java, titled “Java Champion Dick Wall on the Virtues of Scala (Part 2),” Dick Wall explains why, after a long career in programming exploring Lisp, C, C++, Python, and Java, he has finally settled on Scala as his language of choice. From the interview: “I was always on the lookout for a language that would give me both Python-like productivity and simplicity for just writing something and quickly having it work and that also offers strong performance, toolability, and type safety (all of which I like in Java). Scala is simply the first language that offers all those features in a package that suits me. Programming in Scala feels like programming in Python (if you can think it, you can do it), but with the benefit of having a compiler looking over your shoulder and telling you that you have the wrong type here or the wrong method name there.The final ‘aha!’ moment came about a year and a half ago. I had a quick task to complete, and I started writing it in Python (as I have for many years) but then realized that I could probably write it just as fast in Scala. I tried, and indeed I managed to write it just about as fast.”Wall makes the remarkable claim that once Java developers have learned to work in Scala, when they work on large projects, they typically find themselves more productive than they are in Java. “Of course,” he points out, “people are always going to argue about these claims, but I can put my hand over my heart and say that I am much more productive in Scala than I was in Java, and I see no reason why the many people I know using Scala wouldn’t say the same without some reason.”Read the interview here.

• good literature for teaching object oriented thinking in C [closed]

  - by Dipan Mehta

  Quite often C is the primary platform for the development. And when things are large scale, I have seen partitioning of the system as different objects is quite a natural thing. Some or many of the object orientated analysis and design principles are used here very well. This is not a debate question about whether or not C is a good candidate for object oriented programming or not. This is also NOT a question how to do OO in C. You can refer to this question and there are probably many such citations. As far as I am concerned, I have learned some of this things while working with many open source and commercial projects. (libjpeg, ffmpeg, Gstreamer which is based on GObject). I can probably extend a few references that explains some of these concepts such as - 1. Event Helix article, 2. Linux Mag article 3. one of my answers which links Schreiner's reference. Unfortunately, when we induct younger folks, it seems too hard to make them learn all of it the hard way. Usually, when we say it's C, a general reaction is to throw away all of the "Object thinking". Looking for help extending above references from those who have been in the similar areas of work. Are there any good formal literature that explains how Object thinking can be made to use while you are working in C? I have seen tons of book on general "object oriented paradigms" but they all focus on advanced languages mostly not in C. You see most C books - but most focus only on the syntax and the obfuscated corners of C and that's it. There are hardly ANY good reference, specially books or any systematic (I mean formal) literature on how to apply OO in C. This is very surprising given that so many large scale open source projects use C which are truly using this very well; but we hardly see any good formal literature on this subject.

• Failed Project: When to call it?

  - by Dan Ray

  A few months ago my company found itself with its hands around a white-hot emergency of a project, and my entire team of six pulled basically a five week "crunch week". In the 48 hours before go-live, I worked 41 of them, two back to back all-nighters. Deep in the middle of that, I posted what has been my most successful question to date. During all that time there was never any talk of "failure". It was always "get it done, regardless of the pain." Now that the thing is over and we as an organization have had some time to sit back and take stock of what we learned, one question has occurred to me. I can't say I've ever taken part in a project that I'd say had "failed". Plenty that were late or over budget, some disastrously so, but I've always ended up delivering SOMETHING. Yet I hear about "failed IT projects" all the time. I'm wondering about people's experience with that. What were the parameters that defined "failure"? What was the context? In our case, we are a software shop with external clients. Does a project that's internal to a large corporation have more space to "fail"? When do you make that call? What happens when you do? I'm not at all convinced that doing what we did is a smart business move. It wasn't my call (I'm just a code monkey) but I'm wondering if it might have been better to cut our losses, say we're not delivering, and move on. I don't just say that due to the sting of the long hours--the company royally lost its shirt on the project, plus the intangible costs to the company in terms of employee morale and loyalty were large. Factor that against the PR hit of failing to deliver a high profile project like this one was... and I don't know what the right answer is.

• Software Center empty "No usefulness from server" "no username in config file"

  - by Theron G. Burrough

  I upgraded to 12.04 LTS and ran Software Center while a few things were running, and crashed. (2 GB RAM on a Netbook.) On reboot, Ubuntu One interface would not find any programs, neither installed (to run) nor available for download. So I launched Software Center, which opens, but does nothing. I click "Close" button and get a "Force Quit?" box. So I quit. Did research, learned to run Software Center from Terminal: 2012-04-29 23:14:36,978 - softwarecenter.backend.reviews - WARNING - Could not get usefulness from server, no username in config file Then tried the below without success: Reinstallation of software center: sudo apt-get install --reinstall software-center Didn't work. Found this in a post: remove the config file for software-center then log out and back in sudo rm -rf ~/.config/software-center Didn't work. Reinstalled Software Center with Synaptic Package Manager. Still no dice! And I am a Linux newbie, so I don't know where the Dickens that config file is. Help appreciated.

• As my first professional position should I take it at a start-up or a better known company? [closed]

  - by Carl Carlson

  I am a couple of months removed from graduating with a CS degree and my gpa wasn't very high. But I do have aspirations of becoming a good software developer. Nevertheless I got two job offers recently. One is with a small start-up and the other is with a military contractor. The military contractor asked for my gpa and I gave it to them. The military contracting position is in developing GIS related applications which I was familiar with in an internship. After receiving an offer from the military contractor, I received an offer from the start-up after the start-up asked me how much the offer was from the military contractor. So the pay is even. The start-up would require I be immediately thrust into it with only two other people in the start-up currently and I would have to learn everything on my own. The military contractor has teams and people who know what their doing and would be able to offer me guidance. Seeing as how I have been a couple of months removed from school and need something of a refresher is it better than I just dive into the start-up and diversify what I've learned or be specialized on a particular track? Some more facts about the start-up: It deals with military contracts as well and is in Phase 2 of contracts. It will require I learn a diverse amount of technologies including cyber security, android development, python, javascript, etc. The military contractor will have me learn more C#, refine my Java, do javascript, and GIS related technologies. I might as well come out and say the military contractor is Northrop Grumman and more or less offered me less money than the projected starting salary from online salary calculators. But there is the possibility of bonuses, while the start-up doesn't include the possibility of bonuses. I think benefits for both are relatively the same.

• Passed: Exam 70-480: Programming in HTML5 with JavaScript and CSS3

  First off: Mission accomplished successfully. And it was fun! Using the resources listed in my previous article about Learning Content, I'd like to thank Microsoft Technical Evangelists Jeremy Foster and Michael Palermo for their excellent jump start videos on Channel 9, and the various authors at Pluralsight. Local Prometric testing centre Back in November I chose a local testing centre which was the easiest to access from my office despite the horrible traffic you might experience here on the island. Actually, it was not the closest one. But due to their website, their awards as Microsoft Learning Center, and my general curiosity about the premises, I gave FRCI my priority. Boy, how should I regret this decision this morning... The official Prometric exam guide asks any attendee to show up at least 30 minutes prior to the scheduled time of the test. Well, this should have been the easier part but unfortunately due to heavier traffic than usual I arrived only 20 minutes before time. Not too bad but more to come. The building called 'le Hub' is nicely renovated and provides the right environment for an IT group of companies like FRCI. I think they have currently 5 independent IT departments over there. Even the handling at the reception was straight forward, welcoming and at my ease. But then... first shock: "We don't have any exam registration for today." - Hm, that's nice... Here's my mail confirmation from Prometric. First attack successfully handled and the lady went off again to check their records. Next shock: A couple of minutes later, another guy tries to explain me that "the staff of the testing centre is already on vacation and the centre is officially closed." - Are you kidding me? Here's the official confirmation by Prometric, and I don't find it funny that I take a day off today only to hear this kind of blubbering nonsense. I thought that I'll be on the safe side choosing a company with a good reputation here on the island. Another 40 (!) minutes later, they finally come back to the waiting area with a pre-filled form about the test appointment. And finally, after an hour of waiting, discussing, restarting the testing PC, and lots of talk, I am allowed to sit down and take the exam. Exam details Well, you know the rules. Signing an NDA doesn't allow me to provide you any details about the questions or topics that have been covered. Please check out the official exam description, and you're on the right way. Sorry, guys... ;-) The result "Congratulations! You have passed this Microsoft Certification exam." - In general, I have to admit that the parts on HTML5 and CSS3 were the easiest after all, and that I have to get myself a little bit more familiar with certain Javascript features like class definitions, inheritance and data security. Anyway, exam passed - who cares about the details? Next goal Of course, the journey to Microsoft Certifications continues and my next goal is to pass exams 70-481 - Essentials of Developing Windows Store Apps using HTML5 and JavaScript and 70-482 - Advanced Windows Store App Development using HTML5 and JavaScript. This would allow me to achieve the certification of MCSD: Windows Store Apps using HTML5. I guess, during 2013 I'll be busy with various learning and teaching lessons.

• Composing programs from small simple pieces: OOP vs Functional Programming

  - by Jay Godse

  I started programming when imperative programming languages such as C were virtually the only game in town for paid gigs. I'm not a computer scientist by training so I was only exposed to Assembler and Pascal in school, and not Lisp or Prolog. Over the 1990s, Object-Oriented Programming (OOP) became more popular because one of the marketing memes for OOP was that complex programs could be composed of loosely coupled but well-defined, well-tested, cohesive, and reusable classes and objects. And in many cases that is quite true. Once I learned object-oriented programming my C programs became better because I structured them more like classes and objects. In the last few years (2008-2014) I have programmed in Ruby, an OOP language. However, Ruby has many functional programming (FP) features such as lambdas and procs, which enable a different style of programming using recursion, currying, lazy evaluation and the like. (Through ignorance I am at a loss to explain why these techniques are so great). Very recently, I have written code to use methods from the Ruby Enumerable library, such as map(), reduce(), and select(). Apparently this is a functional style of programming. I have found that using these methods significantly reduce code volume, and make my code easier to debug. Upon reading more about FP, one of the marketing claims made by advocates is that FP enables developers to compose programs out of small well-defined, well-tested, and reusable functions, which leads to less buggy code, and low code volume. QUESTIONS: Is the composition of complex program by using FP techniques contradictory to or complementary to composition of a complex program by using OOP techniques? In which situations is OOP more effective, and when is FP more effective? Is it possible to use both techniques in the same complex program? Do the techniques overlap or contradict each other?

• What are some good seminar topics that can be used to improve designer&developer communication?

  - by tactoth

  Hello guys the thing I'll tell is what happens in the company I work for but I know it's more like a common issue in software companies. I'm development team leader in a internet service company that provides service that's very similar to dropbox. In our company we have mainly two divisions: the tech division and the designers division, both have their own reporting hierarchy. Designers focus on designing UI and prioritizing features, while developers focus on implement designers' ideas (more like being driven as our big boss has said). Then here comes our issue: the DEV team and DES team communicate very bad. DEV complain DES for these reasons: Too frequent changing of requirements Too complicated interaction (our DEV team has actually learned many HCI principles) Documents for design are incomplete, usually you just get 'design principles' and it's up to DEV to complete design details. When you find design defects, you ask DES team to resolve them, then DES team quickly change the principles and you gonna spend another several weeks because the change is so fundamental. While DES complain DEV for these reasons: Code architecture is not good enough to adapt to changing requirements (Obviously DES knows something about software development) Product design is about principles, not details. DEV fails to realize this. Communication should be quick and should be mainly oral. Trying to make most feature discussion in document for reference is too overloaded and doesn't make sense. As you can see, DEV and DES have different ideas on product design, and encourages very different practice. We have this difference because of the way we work. So our solution is that we should plan some seminars to make each part more aware of the way the other part work. Then my question is, what are some good topics for such seminars? Guessing some people may not think seminars can solve this problem, please also suggest your solution.

• Retrofit WebForms with ASP.NET MVC - NoVa Code Camp 2010.2 Demo

  - by Soe Tun

  Thank you to everyone who attended my Retrofit WebForms with ASP.NET MVC session at NoVa Code 2010.2. It was a fun event for me and I hope you had a great time and learned something from it. I wish I had more time to go over some more important topics in more detail. I *promise* I will be writing blog post series about it since I'll have some vacation time during the December holidays to cover some topics that I didn't get to cover in detail.   Please note that the ".bak" file included in the zip file is a SQL Server Database backup file. You have to restore it on your Database server to run it with the source code demo.   Please feel free to ask me about the demo project through Twitter or from this blog post. I'll be glad to help you out. If you want me to give this presentation at your .NET User Group, please let me know and I'll be honored to speak there also.   Again, thank you all and have a great holiday season. Here is the download link to my Demo project Zip file with the PowerPoint presentation in it. Please let me know if the link doesn't work.

• Class Design - Space Simulator

  - by Peteyslatts

  I have pretty much taught myself everything I know about programming, so while I know how to teach myself (books, internet and reading API's), I'm finding that there hasn't been a whole lot in the way of good programming. So I have two questions: First the broad one: Does anyone have suggestions as to sources for learning about good programming habits and techniques? I'd prefer it if the resource wasn't a 5000 page tome. The more I can read it in installments the better. More specifically: I am finishing up learning the basics of XNA and I want to create a space simulator to test my knowledge. This isn't a full scale simulator, but just something that covers everything I learned. It's also going to be modular so I can build on it, after I get the basics down. One of the early features I want to implement is AI. And I want to take this into account as I'm designing my classes so I can minimize rewriting code. So my question: How should I design ship classes so that both the player and AI can use them? The only idea I have so far is: Create a ship class that contains stats, models, textures, collision data etc. The player and AI would then have the data for position, rotation, health, etc and would base their status off of the ship stats.

• Learning node.js

  - by john smith

  I am not sure if this is the right place to ask but, I thought this was the most suitable. I recently graduated from university. Learned the full php stack; basically all the LAMP stuff, obviously without counting all the other subjects. Not even got my degree and this whole node.js booming out of nowhere. You can imagine how one can feel about this, the story is always the same: you never end learning, and studying. So I recently got my hands on node.js; reading books, tutorials, and everything imaginable on the internet. The problem is one and simple: this is nowhere near to having a teacher standing near you helping you understanding and solving your problems, especially when all you can do is post your doubts on a website and patiently wait for replies. It's not that it isn't good, it's just much slower than what I just expressed above. So, in short words: is there a place where one can find someone willing to teach you about such contents? This would obviously done via remote means, like skype and such. Can anyone here point me into the right direction? Or just downvote me for being in the wrong website? Thanks in advance.

• How to apply verification and validation on the following example

  - by user970696

  I have been following verification and validation questions here with my colleagues, yet we are unable to see the slight differences, probably caused by language barrier in technical English. An example: Requirement specification User wants to control the lights in 4 rooms by remote command sent from the UI for each room separately. Functional specification The UI will contain 4 checkboxes labelled according to rooms they control. When a checkbox is checked, the signal is sent to corresponding light. A green dot appears next to the checkbox When a checkbox is unchecked, the signal (turn off) is sent to corresponding light. A red dot appears next to the checkbox. Let me start with what I learned here: Verification, according to many great answers here, ensures that product reflects specified requirements - as functional spec is done by a producer based on requirements from customer, this one will be verified for completeness, correctness). Then design document will be checked against functional spec (it should design 4 checkboxes..), and the source code against design (is there a code for 4 checkboxes, functions to send the signals etc. - is it traceable to requirements). Okay, product is built and we need to test it, validate. Here comes our understanding trouble - validation should ensure the product meets requirements for its specific intended use which is basically business requirement (does it work? can I control the lights from the UI?) but testers will definitely work with the functional spec, making sure the checkboxes are there, working, labelled, etc. They are basically checking whether the requirements in functional spec were met in the final product, isn't that verification? (should not be, lets stick to ISO 12207 that only validation is the actual testing)

• How to get started in the development industry? [closed]

  - by Peter Fren

  My life is coding. I was born in 1982 and my first computer was an amiga. I started learning Amiga BASIC. To cut a long story short, I know many things about several programming languages. Being unemployed(I achieved the german abitur, should be similar to a high school degree and I studied a few semesters of mechanical engineering in 2002(I learned JAVA back then)) I have no idea how to use this ability. I have never done commissional work, every task I solved was based on my own wishes and desires. I do not know how to write a FSD or PRD or put it into code. So the question is, why should anyone hire me? I specialized in kinect development but all jobs I applied for on odesk and similar were awarded to others without me knowing why. I don't know what I should do with my skills professionally. What do you suggest? As this board has weird rules, tell me where to find answers if this is the wrong place.

• Speed up ADF Mobile Deployment to Android with Keystore

  - by Shay Shmeltzer

  As you might have noticed from my latest ADF Mobile entries, I'm doing most of my ADF Mobile development on a windows machine and testing on an Android device. Unfortunately the Android/windows experience is not as fast as the iOS/Mac one. However, there is one thing I learned today that can make this a bit less painful in terms of the speed to deploy and test your application - and this is to use the "Release" mode when deploying your application instead of the "Debug" mode. To do this you'll first need to define a keystore, but as Joe from our Mobile team showed me today, this is quite easy. Here are the steps: Open a command line in your JDK bin directory (I just used the JDK that comes with the JDeveloper install). Issue the following command: keytool –genkey –v –keystore <Keystore Name>.keystore –alias <Alias Name> -keyalg RSA –keysize 2048 –validity 10000 Both keystore name and alias names are strings that you decide on. The keytool utility will then prompt you with various questions that you'll need to answer. Once this is done, the next step is to configure your JDeveloper preferences->ADF Mobile to add this keystore there under the release tab:  Then for your application specific deployment profile - switch the build mode from debug to release. The end result is a much smaller mobile application (for example from 60 to 21mb) and a much faster deployment cycle (for me it is about twice as fast as before).

• Sucking Less Every Year ?

  - by AdityaGameProgrammer

  Sucking Less Every Year A trail of thought that had been on my mind for a while Quoting directly from the post I've often thought that sucking less every year is how humble programmers improve. You should be unhappy with code you wrote a year ago. If you aren't, that means either A) you haven't learned anything in a year, B) your code can't be improved, or C) you never revisit old code. All of these are the kiss of death for software developers. How often does this happen or not happen to you? How long before you see an actual improvement in your coding ? month, year? Do you ever revisit Your old code? How often does your old code plague you? or how often do you have to deal with your technical debt. It is definitely very painful to fix old bugs n dirty code that we may have done to quickly meet a deadline and those quick fixes ,some cases we may have to rewrite most of the application/code. No arguments about that. Some of the developers i had come across argued that they were already at the evolved stage where their coding doesn't need improvement or cant get improved anymore. Does this happen? If so how many years into coding on a particular language does one expect this to happen?

• How to deal this situation

  I would like to ask you some guidance here. Once I finished my graduation I join a company for Ruby On Rails. They trained me and put into project for ROR. I have spent 1 year of ROR development. I have done basic things in the given project. Then my company got a project for QT, learned and worked for nearly 7 months. Then my company put into me in iOS development. For the past 1 1/2 years, I have been working in the iOS development till date. Also my main worry is, changing the technology I am working makes me not having in depth knowledge on anything. I mean I can't make myself as expert in any language. What is your opinion? Now my company is going to put me into the cross-platform mobile application development. I am worried now, will this affect my growth path by leaving native development? I am ready to learn Android. As I left web development before 2 year ago, I am finding some odds with me. Should look for iOS job change now? Please let me know your advices.

• Legacy Code Retreat Questions

  - by MarkPearl

  I recently heard of the concept of a Legacy Code Retreat. Since I have attended and helped facilitate some normal Code Retreats I thought it might be interesting in trying a Legacy Code Retreat, but I have a few questions on how a legacy CR differs from a normal one. If anyone has attended a Legacy CR and has some suggestions on how best to host these event’s please leave a comment on what has worked for you in the past or if you have any answers to my questions below… Should you restrict the languages that people can do the sessions in? In the normal CR’s I have been involved in the past we have had people attend and code in their programming language of choice. A normal CR lends itself to  this because each session starts with no code. With a legacy CR each session seems to start with an existing code base. Is there some sort of limitation on the languages that people can work in during the sessions? If not, how do you give them a base to start from? What happens as the beginning of each session? In the normal CR that I have attended each session would have a constraint set on it – i.e. no if statements used, no primitives, etc. With a legacy CR it seems more like patterns for refactoring are learned. Does the facilitator explain the pattern used before the session starts or are they just given a code base to start from and an objective to achieve

• How exactly to implement multiple threads in a game

  - by xerwin

  So I recently started learning Java, and having a interest in playing games as well as developing them, naturally I want to create game in Java. I have experience with games in C# and C++ but all of them were single-threaded simple games. But now, I learned how easy it is to make threads in Java, I want to take things to the next level. I started thinking about how would I actually implement threading in a game. I read couple of articles that say the same thing "Usually you have thread for rendering, for updating game logic, for AI, ..." but I haven't (or didn't look hard enough) found example of implementation. My idea how to make implementation is something like this (example for AI) public class AIThread implements Runnable{ private List<AI> ai; private Player player; /*...*/ public void run() { for (int i = 0; i < ai.size(); i++){ ai.get(i).update(player); } Thread.sleep(/* sleep until the next game "tick" */); } } I think this could work. If I also had a rendering and updating thread list of AI in both those threads, since I need to draw the AI and I need to calculate the logic between player and AI(But that could be moved to AIThread, but as an example) . Coming from C++ I'm used to do thing elegantly and efficiently, and this seems like neither of those. So what would be the correct way to handle this? Should I just keep multiple copies of resources in each thread or should I have the resources on one spot, declared with synchronized keyword? I'm afraid that could cause deadlocks, but I'm not yet qualified enough to know when a code will produce deadlock.

• Ops Center 12c - Update - Provisioning Solaris on x86 Using a Card-Based NIC

  - by scottdickson

  Last week, I posted a blog describing how to use Ops Center to provision Solaris over the network via a NIC on a card rather than the built-in NIC.  Really, that was all about how to install Solaris on a SPARC system.  This week, we'll look at how to do the same thing for an x86-based server. Really, the overall process is exactly the same, at least for Solaris 11, with only minor updates. We will focus on Solaris 11 for this blog.  Once I verify that the same approach works for Solaris 10, I will provide another update. Booting Solaris 11 on x86 Just as before, in order to configure the server for network boot across a card-based NIC, it is necessary to declare the asset to associate the additional MACs with the server.  You likely will need to access the server console via the ILOM to figure out the MAC and to get a good idea of the network instance number.  The simplest way to find both of these is to start a network boot using the desired NIC and see where it appears in the list of network interfaces and what MAC is used when it tries to boot.  Go to the ILOM for the server.  Reset the server and start the console.  When the BIOS loads, select the boot menu, usually with Ctrl-P.  This will give you a menu of devices to boot from, including all of the NICs.  Select the NIC you want to boot from.  Its position in the list is a good indication of what network number Solaris will give the device. In this case, we want to boot from the 5th interface (GB_4, net4).  Pick it and start the boot processes.  When it starts to boot, you will see the MAC address for the interface Once you have the network instance and the MAC, go through the same process of declaring the asset as in the SPARC case.  This associates the additional network interface with the server.. Creating an OS Provisioning Plan The simplest way to do the boot via an alternate interface on an x86 system is to do a manual boot.  Update the OS provisioning profile as in the SPARC case to reflect the fact that we are booting from a different interface.  Update, in this case, the network boot device to be GB_4/net4, or the device corresponding to your network instance number.  Configure the profile to support manual network boot by checking the box for manual boot in the OS Provisioning profile. Booting the System Once you have created a profile and plan to support booting from the additional NIC, we are ready to install the server. Again, from the ILOM, reset the system and start the console.  When the BIOS loads, select boot from the Boot Menu as above.  Select the network interface from the list as before and start the boot process.  When the grub bootloader loads, the default boot image is the Solaris Text Installer.  On the grub menu, select Automated Installer and Ops Center takes over from there. Lessons The key lesson from all of this is that Ops Center is a valuable tool for provisioning servers whether they are connected via built-in network interfaces or via high-speed NICs on cards.  This is great news for modern datacenters using converged network infrastructures.  The process works for both SPARC and x86 Solaris installations.  And it's easy and repeatable.
