• Learning c++ by contributing to open source projects

  - by user1189880

  I have some general programming experience with a few different languages, my most skilled being php. I want to spend a lot of time over the next year learning c++ in much more depth and then eventually get to a good enough level to find a job as a junior developer working in c++. I really struggle to find things to develop as toy programs so want to contribute to an open source project in c++ to get really stuck in to. But the projects I see on github in c++ are very large and will require a lot of knowlege to even get started. Are there any smaller projects that I can contribute to or are there any other good ideas for learning c++ from a practical level.

• Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. Access is denied.

  I wanted to post a solution to an issue that comes up every time I have to setup a new developer in our organization:      Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. Access is denied.  My solution is to grant Full Control to the "Everyone" group to the folder C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files  I know there are other solutions to this problem, but this one seems the simplest for me.  M...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• C# return variables

  - by pb01

  In a debate regarding return variables, some members of the team prefer a method to return the result directly to the caller, whereas others prefer to declare a return variable that is then returned to the caller (see code examples below) The argument for the latter is that it allows a developer that is debugging the code to find the return value of the method before it returns to the caller thereby making the code easier to understand: This is especially true where method calls are daisy-chained. Are there any guidelines as to which is the most efficient and/or are there any other reasons why we should adopt one style over another? Thanks private bool Is2(int a) { return a == 2; } private bool Is3(int a) { var result = a == 3; return result; }

• When to roll your own game engine?

  - by Joey Green

  I've been a software developer for 5 years now and wanting to get into iOS game development. I've played around with the iOS SDK for about 2 years now, attending cocoaheads meetings and feel I have a good grasp on objective-c/cocoa and even c/c++. I have a game idea and know that I will use Box2D but I'm wondering if I should use cocos2D or not. The main reasons are: I may want to do things graphics wise that aren't available in cocos2d. If I roll my own game engine I'll have more control. Of course the main reason for using a already existing game engine is the time it saves and it makes the hard stuff easier, but for someone who has the technical chops to roll his own does it make sense?

• Can the customer be a SCRUM Product Owner in a project?

  - by Morten

  I just had a discussion with a colleague about the Product Owner role: In a project where a customer organization has brought in a sofware developing organization (supplier), can the role of Product Owner be successfully held by the customer organization, or should it always be held by the supplier? I always imagined, that the PO was the supplier organizations guy. The guy that ensured that the customer is happy, and continously fed with new and high-businessvalue functionality, but still an integral part of the developer organization. However, maybe I have viewed the PO role too much like the waterfall project manager. My colleague made me think: If the customer organization is mature and proffessional enough, why not let a person from their camp prioritize the backlog?? That would put the PO role much closer to the business, thus being (in theory) better to assess the business value of backlog items. To me, that is an intriguing thought. But what are the implication of such a setup??? I look forward to your input.

• what is best book to learn optimized programming in java [closed]

  - by Abhishek Simon

  Possible Duplicate: Is there a canonical book for learning Java as an experienced developer? Let me elaborate a little: I used to be a C/C++ programmer where I used data structure concept like trees, queues stack etc and tried to optimize as much as possible, minimum no. of loops, variables and tried to make it efficient. It's been a couple of years that I started writing java codes, but it is simply not that efficient in terms of performance, memory intensive etc. To the point: I want to enter programming challenges using java so I need to improve my approach at things I program. So please suggest me some books that can help me learn to program better and have a chance in solving challenges in programming.

• Send and Receive SMS from my Website [on hold]

  - by Weng Fai Wong

  The way I plan to use it is: Have people send SMS to a number to vote. On the backend (assuming that the data comes back to my Web server), I will display the voting results on my Web site. After say 10 minutes, I would like to press a button on my Web site so ONE of the people who sent an SMS earlier receive an SMS saying that person is a winner. I'm an ASP .Net developer, so I just need an API to code against. One such company I saw that does this (but is limited to US) is: http://www.twilio.com/sms/ Do you know any international providers that are similar to Twilio SMS? I'm based in Sydney, Australia. I've looked through the discussion here but could not find any International provider that does what Twilio SMS does: How to add SMS text messaging functionality to my website? Thank you.

• Installing PHP extensions on Linux

  - by EmmyS

  Please bear with me; I'm a developer, not a server admin. My company wants to explore using Magento. They've handed me a pre-configured Linux server with apache and PHP installed, but when I try to run the Magento setup, it tells me that there are PHP extensions that need to be loaded. I can edit the php.ini file, but have no idea where to get the extensions or how to install them, and there's no one here who knows, either. Can anyone give me a hand? I need the PDO_MySQL, mcrypt, and GD extensions. I've searched and found sites that talk about downloading from the terminal and compiling code, but it's all way over my head. Is there an easy way to do this?

• Executing Shell Commands - PHP or Python?

  - by chadpeppers

  I know basically two languages: Python and PHP. I am primarily a Drupal developer. I have a great idea in creating a command line program that will help some of the mundane tasks and bring my efficiency up quite a bit. The concept is that of a complete console program, almost like the days when I learned C++ using stdin/out. I want to use this came concept but for this program. I am going to be executing shell commands (mainly drush commands, if you are familiar with drush its drupals way of doing tasks like installing drupal, clearing cache, and other things). I am also wanting to do a database and save/execute through multiple objects and site profiles. My general question is this. Which language would be better suited to handle command line code? Drupal is written in PHP so I am leaned more towards that,but I know python seems to handle console programming a bit easier. Any help would be great!

• Which tools you use to make gtk themes?

  - by tutuca

  I'm trying to make a new gtk theme using the murrine engine, using Humanity (default in ubuntu 9.10) as a template. You can grab the code in http://github.com/tutuca/themes However, I found cumbersome the process of creating a new theme with it. There is no central starting point. The documentation of both, the engine options (gtkrc's and stuff), and general theming practices (the format of the index.theme files, folders, bla bla) is scarce, How to's and tutorials are often old or subject to lots of opinionated debate and results confusing (to me, having a web developer background, at least :-). So... I wanted to ask to the fellows gtk themers and artist out there: Which tools you use to create a new theme, and how does your average workflow looks like?

• SQL, moving million records from a database to other database [migrated]

  - by Ryoma

  I am a C# developer, I am not really good with SQL. I have a simple questions here. I need to move more than 50 millions records from a database to other database. I tried to use the import function in ms SQL, however it got stuck because the log was full (I got an error message The transaction log for database 'mydatabase' is full due to 'LOG_BACKUP'). The database recovery model was set to simple. My friend said that importing millions records using task-import data will cause the log to be massive and told me to use loop instead to transfer the data, does anyone know how and why? thanks in advance

• Video Training Courses for Linux/Ubuntu?

  - by Anil

  I'm a software developer with more than 15 years of experience on Windows platform, focused on C#/.NET/SQL Server stack. Recently I decided to explore Linux and learn a new development technology stack which is completely unrelated to Microsoft. After a bit of (re)search/reading I picked Ubuntu as my starting point. As I'm really a Pluralsight addict, preferring video courses as a starting point for learning new stuff, I wanted to ask if there are any decent video courses for Linux generally or Ubuntu focused ones? Basically I'm searching for general explanation of OS structure, a bit of system administration, and maybe some considerations for development on Linux system.

• Thoughts on Development using Virtual Machines

  - by J_A_X

  I'll be working as a development lead for a startup and I've suggested that we use VMs for development. I'm not talking about each developer having a desktop with VMs for testing/development, I mean having a server rack where all VMs are managed and have the developers work from a microPC (ChromeOS anyone?) locally, or even remotely from their home computer. To me, the benefits are the fact that it's extremely scalable, cheaper in the long run, easier to manage and that we utilize the hardware its maximum potential. As for cons, I can't think of any particular showstoppers other than we'll need someone to setup/maintain said setup. I was hoping that some of you might of had a similar setup at your place of employment and be able to weight in with your opinions. Thanks.

• Why isn't Java more widely used for game development?

  - by Anto

  I'm not a game developer or anything, but I know that Java is not very widely used for game development. Java should be fast enough for most games, so where's the catch? I can think of some reasons: Lack of game developers with expertice in Java Lack of good game development frameworks Programmers don't want to accept Java as a games programming language. Most only accept C++ as that? No support for game consoles (though the PC market still exists) It could of course be something else. Could someone who knows the business better than me explain why Java isn't getting momentum when it comes to game development?

• Lenovo ThinkPad T400 and docking station

  - by hari

  Developer in me woke up this morning and asked me to fix this before Christmas. (As his Christmas gift). So, if I power on the laptop after docking it, everything works fine. But if I am working on it standalone and then try to dock it, I cannot get the display. Same way, if I undock it while working, I loose the display. Basically, I need to reboot for any docking/undocking dance to work. Questions: 1) What kind of information should I be looking for to understand the problem? 2) Where to find that information. After this, I can go and try to figure out what is going wrong.

• How do you react to non-programmers with ideas of 'The Next Big Thing' ?

  - by jiceo

  Recently and quite often, people with no programming background come and say they have this great idea that can be the next big thing and that the idea(s) is worth a fortune by itself. Then as they know I'm a programmer, they ask me if I'm willing to "code it up" for them or find someone willing to do it for next to nothing. Judging from the enthusiasm, it's like they're drunk on their idea and that that by itself is the most important thing, but they just need a programmer. My response to them, depending on my mood and their general attitude towards what we do, is something along the lines of: "Having the core of an idea is one thing. Developing it to the point that it becomes a platform that changes the world in which it lives is another, and you're going to be willing to pay proportionately to how big you think your idea is worth." Have you been approached by these business type entrepreneurs (with no technical/developer's knowledge) with such a proposal and how do you react to them?

• Can jobs limit future career paths?

  - by Kenneth

  I'm at the beginning of my career and I'm currently looking for jobs. I'm wondering to what extent choosing a particular job would limit future job options. I know that the farther you get away from college graduation the more employers look at your experience vs your actual degree. So I'm wondering with the ultimate goal of being in software engineering/computer science would taking a job in the IT realm limit my options of getting into software engineering? Likewise would taking a job in software quality assurance limit me from pursuing more of a main developer position later even though both are in software engineering?
