• ASP.NET MVC ....or.... PHP, Python, Ruby, Java...?

  - by Muaz Khan

  I’m using ASP.NET MVC in C# and jQuery as well as Ajax. A lot of other web technologies confuse me: PHP, Python, Ruby, Java (or C++) etc. What is your opinion about ASP.NET MVC? Should I choose something else? Today, everyone says, “PHP” is worldly used language..!! And that’s true!!! I’m confused, much confused about my future career. I’m worried I’m not going in right direction! Or for making my future brighter, whether I should choose something else other than ASP.NET MVC and C#. And what would that something else be? I want to be a web developer that can do everything with web (and for web). I’m worried if I’m wasting my time with ASP.NET MVC!!!

• OpenGL ES Basic Fragment Shader help with transparency

  - by Chris

  I have just spent my first half hour playing with the shader language. I have modified the basic program I have which renders the texture, to allow me to colour the texture. varying vec2 texCoord; uniform sampler2D texSampler; /* Given the texture coordinates, our pixel shader grabs the corresponding * color from the texture. */ void main() { //gl_FragColor = texture2D(texSampler, texCoord); gl_FragColor = vec4(0,1,0,1)*vec4(texture2D(texSampler,texCoord).xyz,1); } I have noticed how this affects my transparent textures, and I believe I am loosing the alpha channel which would explain why previously transparent area's appear totally black. If I use the following line instead, I am shown the transparent area's gl_FragColor = vec4(0,1,0,1)*vec4(texture2D(texSampler,texCoord).aaa,1); How can I retain the transparency after this modification to the colour? I have seen various things about a .w property, and also luminous, but my tweaks with those and the .aaa property are not working XD

• Can the Clojure set and maps syntax be added to other Lisp dialects?

  - by Cedric Martin

  In addition to create list using parentheses, Clojure allows to create vectors using [ ], maps using { } and sets using #{ }. Lisp is always said to be a very extensible language in which you can easily create DSLs etc. But is Lisp so extensible that you can take any Lisp dialect and relatively easily add support for Clojure's vectors, maps and sets (which are all functions in Clojure)? I'm not necessarily asking about cons or similar actually working on these functions: what I'd like to know is if the other could be modified so that the source code would look like Clojure's source code (that is: using matching [ ], { } and #{ } in addition to ( )). Note that if it cannot be done this is not a criticism of Lisp: what I'd like to know is, technically, what should be done or what cannot be done if one were to add such a thing.

• 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'?

• Sprites as Actors

  - by Scán

  Hello, I'm not experienced in GameDev questions, but as a programmer. In the language Scala, you can have scalable multi-tasking with Actors, very stable, as I hear. You can even habe hundreds of thousands of them running at once without a problem. So I thought, maybe you can use these as a base class for 2D-Sprites, to break out of the game-loop thing that requires to go through all the sprites and move them. They'd basically move themselves, event-driven. Would that make sense for a game? Having it multitasked like that? After all, it will run on the JVM, though that should not be much of a problem nowadays.

• How to elevate engineering culture at large corporations?

  - by davidk01

  One thing I have realized working at a large corporation is that it doesn't matter how smart you are because if everyone else doesn't see the value in what you are doing then you are not going to get very far. It's much harder to convince 1000 people that a certain part of the software stack should be in groovy than it is to convince 10 people of the same thing. I'm curious how people go about elevating the engineering culture at large corporations because I've been running into walls left and right and I would like to be more proactive about how I go about it. I have been advocating tech talks and tech demos along with code reviews as potential solutions. Do people have other suggestions? Note that 1000 people and groovy are just representative examples. I am not married to groovy or any other language and 1000 people is meant to indicate large scale and how to go about teaching a large group of people about best practices and engineering principles in general.

• PHP developer wanting to learn python

  - by dclowd9901

  I'm pretty familiar at this point with PHP (Javascript, too), up to the point of OOP in PHP, and am looking to branch out my knowledge. I'm looking at Python next, but a lot of it is a bit alien to me as a PHP developer. I'm less concerned about learning the language itself. I'm positive there's plenty of good resources, documentation and libraries to help me get the code down. I'm less sure about the technical aspects of how to set up a dev environment, unit testing and other more mundane details that are very important, aid in rapid development, but aren't as widely covered. Are there any good resources out there for this?

• Small-Scale Physics Engine

  - by user1276078

  I'm entering Android game development, and I already have a computer version of a game I want to publish. The thing is, I want to make this as good as it can be. With that said, I need a physics engine, really to only do one thing. That one thing is to make a parabolic movement of my main character as he's jumping in the air. Currently, my computer version simply makes the guy move up at a 45 degree angle, and as soon as it hits the ceiling, down at a 45 degree angle. I need a physics engine/library that would accomplish that, it has to be in java since that's my best language, it has to be 2D, and it has to be able to work on Android. Which physics engine/library could accomplish all of that?

• I can't program because old coding style. This is normal to programmers?

  - by Renato Dinhani Conceição

  I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: don't have comments don't have functions (50, 100, 200, 300 or more lines executed in sequence) uses a lot of if statements with a lot of paths has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) uses a language I am unfamiliar with (Visual FoxPro 8 from 2002) I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way?

• junior / professional / senior categorization

  - by oozoo

  Hey guys, is it just me or is the categorization of developer levels highly subjective? I get the feeling that every company tries to hire experienced developers as juniors because they don't know $technology. For example my own career: I switched technologies a couple of times, while sticking to java as a programming language. For example I first worked for 3 years using JavaSE technologies, the next company I worked for hired me as junior because I didn't have JavaEE experience - while still selling me as professional level to customers (I work in consulting). The next company hired me again as junior because I didn't have SAP experience - they mostly work with SAP Java technologies which is definitely a niche. Still, they are selling all their technology consultants for exactly the same rate while paying them significantly different wages. Now when switching jobs again I feel like this whole thing is going to start all over again because I don't have Spring experience or Oracle knowledge. tl;dr = is my observation totally off base that companies are just using these categorizations as means to keep down wages?

• Is there such a thing as too much experience?

  - by sunpech

  For modern software developers in today's world, is there such a thing as having too much experience with a certain technology or programming language? To a recruiter, interviewer, or company hiring-- could there often be cases where a particular candidate has so much experience in a certain area or technology where it works against the candidate to being hired? I'm not talking about cases where a senior developer is applying for an entry-level developer position, and has a lot of experience in that sense. Nor am I talking about cases where a candidate is outright lying (e.g. 20+ years experience with Ruby on Rails). I've overheard this in conversations between hiring managers/developers during happy hours, yet I'm not quite sure I fully understand what they mean.

• C library build system dependencies

  - by Ninefingers

  Hello all, This debate has cropped up on a mailing list for a project I'm involved in. Unfortunately we're quite a small bunch at the moment, so I want to ask a wider audience. We're writing a C library (for arbitrary precision arithmetic) and are investigating build systems. Currently we have a bash script in desperate need of work. I believe we can't use autotools etc due to licensing (bsd vs gpl). So I suggested we use a modern scripting language like python or perl. The question is: is having something like perl or python around at build time an unrealistic dependency on Unix-like platforms these days?

• What are the warning signs of impending doom to watch out for on a project?

  - by ConroyP

  Having worked on a failed project is one of the few things that most programmers have in common, regardless of language used, industry or experience. These projects can be great learning experiences, soul-crushing disasters (or both!), and can occur for a multitude of reasons: upper management change of heart under-skilled / under-resourced team emergence of superior competitor during dev cycle over/under management Once you've worked on a couple of such projects, is it possible to recognise at an early stage exactly when a project is doomed to fail? For me, a big sign is having a hard & fast external deadline combined with feature creep. I've seen projects which were well planned out and proceeding right on schedule go horribly off the rails once the late feature requests started to roll in and get added to the final "deliverable". The proposers of these requests earned the nickname of Columbo, due to rarely leaving the room without asking for "just one more thing". What are the warning signs you look out for that set off the alarm bells of impending doom in your head?

• What languages are most commonly used in medical research?

  - by Chris Taylor

  For someone about to go into a career in medical research, what language would be the most useful to learn? From my limited experience (I have been a researcher in mathematics and in finance) I have been able to recommend looking at R (for statistics) Matlab (for general numeric processing) and Python (for general purpose programming with statistics/numerics as an add-on) but I don't know which of those (if any) are in common use -- or if there are other, more specialized languages that are used. To be clear, I'm not talking about a professional programmer working in a medical setting. I am talking about a medical or genetics researcher who uses programming to analyse data, or generally to help get their work done.

• Google Analytics - Unable to get GA Tracking

  - by Pure.Krome

  We've been using GA for a few years with no probs. About 2-3 weeks ago we tried to clean up some of our tracking and on one of our profiles, it's not working anymore (since oct 10.) First, some context then some GA Debugging code. 1. Context. We have the following setup: different root domains AND different sub-domains on one of the root domains. www.website.com www.website.com.au www.anotherWebsite.com foo.website.com baa.website.com So what we're doing is the following: each root domain and each sub-domain get their own tracking code. This way we can allow separate people (from outside our company) to access only their own data. Eg. a manager for foo.website.com can only see data related to that domain .. and see data on the other domains. Have a last account which is the SUM of all the domains. this is for us. so we can see total numbers. So to do this, we have two trackers that fire off, on the page. the individual accounts all work fine - they seem to be tracking data ok. the 'global' account is not working and this gives us the = Tracking Not Installed error. This has been going on since oct 10. So the wait 24/48/72 hours thing is waaaaay over. 2. GA Debug code. Installing GA Debug chrome extension gives the following output. I've tried to hide anything that could be considered secret. UA-XXXXX34-1 == Global account (which isn't working any more). UA-XXXXX34-11 == Specific account for www.website.com _gaq.push processing "_setAccount" for args: "[UA-XXXXX34-1]": ga_debug.js:18 _gaq.push processing "_setDomainName" for args: "[website.com]": ga_debug.js:18 _gaq.push processing "_setAllowLinker" for args: "[true]": ga_debug.js:18 _gaq.push processing "_trackPageview" for args: "[]": ga_debug.js:18 Track Pageview ga_debug.js:18 Tracking beacon sent! utmwv=--snipped-- Account ID : UA-XXXX234-1 Page Title : Some page title Host Name : www.website.com Page : / Referring URL : - Hit ID : 1923583969 Visitor ID : 785310647 Session Count : 51 Session Time - First : Thu Aug 23 2012 15:20:17 GMT 1000 (AUS Eastern Standard Time) Session Time - Last : Mon Oct 29 2012 11:41:46 GMT 1100 (AUS Eastern Summer Time) Session Time - Current : Mon Oct 29 2012 12:19:23 GMT 1100 (AUS Eastern Summer Time) Campaign Time : Thu Aug 23 2012 15:20:17 GMT 1000 (AUS Eastern Standard Time) Campaign Session : 1 Campaign Count : 1 Campaign Source : (direct) Campaign Medium : (none); Campaign Name : (direct) Language : en-gb Encoding : UTF-8 Flash Version : 11.4 r31 Java Enabled : true Screen Resolution : 1050x1680 Browser Size : 1033x861 Color Depth : 32-bit Ga.js Version : 5.3.7d Cachebuster : 1846514973 ga_debug.js:18 _gaq.push processing "_setAccount" for args: "[UA-XXXX234-11]": ga_debug.js:18 _gaq.push processing "_setDomainName" for args: "[website.com]": ga_debug.js:18 _gaq.push processing "_setAllowLinker" for args: "[true]": ga_debug.js:18 _gaq.push processing "_trackPageview" for args: "[]": ga_debug.js:18 Track Pageview ga_debug.js:18 Tracking beacon sent! utmwv=--snipped-- Account ID : UA-XXXX234-11 Page Title : SomePageTitle Host Name : www.website.com Page : / Referring URL : - Hit ID : 1923583969 Visitor ID : 785310647 Session Count : 51 Session Time - First : Thu Aug 23 2012 15:20:17 GMT 1000 (AUS Eastern Standard Time) Session Time - Last : Mon Oct 29 2012 11:41:46 GMT 1100 (AUS Eastern Summer Time) Session Time - Current : Mon Oct 29 2012 12:19:23 GMT 1100 (AUS Eastern Summer Time) Campaign Time : Thu Aug 23 2012 15:20:17 GMT 1000 (AUS Eastern Standard Time) Campaign Session : 1 Campaign Count : 1 Campaign Source : (direct) Campaign Medium : (none); Campaign Name : (direct) Language : en-gb Encoding : UTF-8 Flash Version : 11.4 r31 Java Enabled : true Screen Resolution : 1050x1680 Browser Size : 1033x861 Color Depth : 32-bit Ga.js Version : 5.3.7d Cachebuster : 1580443754 and this is the js code he have.

• Should a programmer take writing lessons to enhance code expressiveness?

  - by Jose Faeti

  Given that programmers are authors and write code to express abstract thoughts and concepts, and good code should be read by other programmers without difficulties and misunderstandings, should a programmer take writing lessons to write better code? Abstracting concepts and real world problems/entities is an important part of writing good code, and a good mastery of the language used for coding should allow the programmer to express his thoughts more easily, or in a better way. Besides, when trying to write or rewrite some code to make it better, much time can be spent in deciding the names for functions, variables or data structures. I think this could also help to avoid writing code with more than one meaning, often cause of misunderstanding between different programmers. Code should always express clearly its function unambiguously.

• How do I create a PPA for a working program?

  - by d3vid

  Let's assume I have a working application written in C, C++ or Python. I want to create a Launchpad PPA so others can easily install it from a package. Please give step by step instructions for doing this from beginning to end. (Or provide a link that does the same ;) Does the programming language matter? (Could it be a bash script?) Do I need to add anything to my build? Where should the build install itself to? How do I define dependencies? How do I use dependencies? How do I create a .deb? What do I need to do before uploading to Launchpad?

• How do you go about training a replacement?

  - by SnOrfus

  I recently asked about leaving a position and got a lot of great answers. One of the common threads was that being around to train the new person would be expected and could go a long way. Now considering that (I think) most people don't stay at a company for a long time after they've given notice, and it will take time for the company to interview/hire one - that leaves for a short amount of time to get someone up to speed. I've also never trained anyone before. I did a bunch of tutoring in University and College, but teaching a language/technology is far different from training someone to replace you on your job. So the question is: how do you go about training someone to replace you in a, potentially, short amount of time?

• Where To Begin To Make A Website

  - by lolyoshi

  I'm a newbie in web programming. I haven't done anything that relates to website before. Now, my new task is creating a website using Java, Jsp, HTML, CSS, mySQL, Apache and Spring Framework (MVC model). I want to know what I should research if I want my website has the function as post entries, comment entries, delete entries, edit entries, etc as a forum? Which I need to know beside above things? I don't know how to update my website automatically when there're changes in website as the top view products, the best products. I don't think I'll input or change them manually. So, which tools or language can support that? Thank for advance

• One method with many behaviours or many methods

  - by Krowar

  This question is quite general and not related to a specific language, but more to coding best practices. Recently, I've been developing a feature for my app that is requested in many cases with slightly different behaviours. This function send emails , but to different receivers, or with different texts according to the parameters. The method signature is something like public static sendMail (t_message message = null , t_user receiver = null , stream attachedPiece = null) And then there are many condition inside the method, like if(attachedPiece != null) { } I've made the choice to do it this way (with a single method) because it prevents me to rewrite the (nearly) same method 10 times, but I'm not sure that it's a good practice. What should I have done? Write 10 sendMail method with different parameters? Are there obvious pros and cons for these different ways of programming? Thanks a lot.
