• C# development with Mono and MonoDevelop

  - by developerit

  In the past two years, I have been developing .NET from my MacBook by running Windows XP into VM Ware and more recently into Virtual Box from OS X. This way, I could install Visual Studio and be able to work seamlessly. But, this way of working has a major down side: it kills the battery of my laptop… I can easiely last for 3 hours if I stay in OS X, but can only last 45 min when XP is running. Recently, I gave MonoDevelop a try for developing Developer IT‘s tools and web site. While being way less complete then Visual Studio, it provides essentials tools when it comes to developping software. It works well with solutions and projects files created from Visual Studio, it has Intellisence (word completion), it can compile your code and can even target your .NET app to linux or unix. This tools can save me a lot of time and batteries! Although I could not only work with MonoDevelop, I find it way better than a simple text editor like Smultron. Thanks to Novell, we can now bring Microsoft technology to OS X.

• Shared Development Space

  - by PatrickWalker

  Currently the company I work in gives each developer their own development virtual machine. On this machine (Windows 7) they install the entire stack of the product (minus database) this stack is normally spread amongst multiple machines of differing OS (although moving towards windows 2008 and 2008r2) So when a developer has a new project they are likely to be updating only a small piece of their stack and as such the rest of it can become out of date with the latest production code. The isolation from others means some issues won't be found until the code goes into shared test environments/production. I'm suggesting a move from functional testing on these isolated machines to plugging machines into a shared environment. The goal being to move towards a deployment thats closer to production in mechanism and server type. Developers would still make code changes on their Win7 vm and run unit/component testing locally but for functionally testing they would leverage a shared enviornment. Does anyone else use a shared development environment like this? Are there many reasons against this sort of sandbox environment? The biggest drawback is a move away from only checking in code when you've done local functional testing to checking in after static testing. I'm hoping an intelligent git branching strategy can take care of this for us.

• Web application development over C++ development..

  - by learnerforever

  Hi, I am CS undergrad and CS grad. In college I used to program in C/C++/java and have pretty much stuck to the same skill set in industry with 3 years experience. I like thinking,reading,applying logic etc, designing data structures, but I have little patience with debugging large C++ code. And having to deal with low level stuff like memory fault,memory corruption,compilation/linking issues. My confidence in programming is getting down due to this, but I like being in technical field. Does web application development like LAMP suit (Linux,apache,mysql,php),CSS,scripting (AMONG OTHER WEB DEVELOPMENT RELATED SKILLS) etc need lesser patience with debugging,and understanding of low level stuff, but your analysis/logical skills also get used? Also opportunities in web application development look more. Things like scalability, most of the stuff that Google does fascinates me, but for patience needed for dealing with C++ debugging. I make blunders while coding. How does the field look like outside C++? I am beginning to wonder if as a female, by moving to web application development, I can better manage work life balance. I have seen relatively lesser females in C++ than in Java/.net. Not very sure about web related stuff though. Also, what are the other hot technologies being used in web application development? lamp,css is something I know vaguely. Not in touch with keywords going on in this area. Please help!!.

• Mobile Development- Obtaining development hardware - best practices?

  - by Zoot

  I'm looking to get into smartphone development, but there a quite a few options out there for platforms right now. (iOS/Android/WebOS/Bada/Symbian/MeeGo/WindowsMobile/JavaME) I'd like to have development hardware to test my code and the overall functionality of the devices. What is the best way to obtain and/or borrow hardware for development and testing? Are there rules of thumb to follow which apply to all companies and platforms? In this situation, I'm a single developer. Does this process change for a startup? A hackerspace? A small business? A large business? Thanks.

• Trade-offs of local vs remote development workflows for a web development team

  - by lamp_scaler

  We currently have SVN setup on a remote development server. Developers SSH into the server and develops on their sandbox environment on the server. Each one has a virtual host pointed to their sandbox so they can preview their changes via the web browser by connecting to developer-sandbox1.domain.com. This has worked well so far because the team is small and everyone uses computers with varying specs and OSs. I've heard some web shops are using a workflow that has the developers work off of a VM on their local machine and then finally push changes to the remote server that hosts SVN. The downside to this is that everyone will need to make sure their machine is powerful enough to run both the VM and all their development tools. This would also mean creating images that mirror the server environment (we use CentOS) and have them install it into their VMs. And this would mean creating new images every time there is an update to the server environment. What are some other trade-offs? Ultimately, why did you choose one workflow over the other?

• Web versus desktop development - is web development worse?

  - by Josh Kelley

  As a longtime desktop developer looking at doing our first large-scale web application, what are the pros and cons of doing web development? Is developing a web application much worse than developing a desktop app? E.g., is it more tedious or annoying? Is the time to market much worse? Is the web platform excessively limiting? If the answer to any of these is yes, then why? (And how does developing a Flash or Silverlight app compare?)

• Going into Web Development without a C.S. Degree - Suggestions

  - by Klaint Cokeman

  I plan on seeking a career in web development and I'm about two semesters away from graduating with a CIS degree. Although I'm very satisfied with my choice of degree, I'm concerned that I may be lacking knowledge in a few areas because of not majoring in computer science. The programming side of things is no problem for me, I'm just wondering to what extent data structures/theory/etc. might benefit me to learn over spending more time with hands-on programming... and also what aspects of C.S. would be most appropriate to look into you would think would be most applicable to web development. In short, I'd like to expand my horizons a little bit. I'd very much appreciate and advice/suggestions/book or tutorial recommendations, etc. Thanks.

• Web development starting a career [closed]

  - by user985482

  Hi I am in the 3rd and last year at college of informatics and I am interested to follow a career in web development when I finish(2 more months). From what I understand this days to get hired you need to be able to know a variety of technologies at least that is the case in Romania.Most of the jobs I have seen even at entry level asks you to know the following: HTML/CSS Javascript , a framework preferable jQuery , Ajax a server side language in my case PHP and a framework SQL and an RDBMS in my case MySql a CMS in my case Wordpress My question is how well should me or anyone looking to get hired as a web developer for there first job should we know this technologies in order to get hired and what else should we aim to learn to have a better chance of getting hired. I don't know if the question is right for this forum but I believe that this could help many of the students and anyone who is taking an interest in web development to know what they should expect from there employers when they try to find work.

• Technical development decision for my newly established software company

  - by test test

  I have a new software company where I am planning to develop CRM system. So I have settled down on the technological approach I am going to use:- I will use an open source Java-based CRM engine. I will use a third party reporting tool named JasperReports for providing reports capabilities for the CRM. I will develop the interface and any customization which the customer might ask for using asp.net mvc framework since my knowledge and experience are based on asp.net. And I will use the CRM API to integrate my asp.net web application with the Java-based CRM. I have developed a simple demo which integrate these three main components (CRM engine, asp.net application and the reporting tool) and they worked well. But I am afraid of the following risk that I might face if I go with the above approach: I should hire developers with different skills and experience: Developers with Java skills to be able to modify the Java-based CRM and writing plug-ins -when needed- to extend the CRM capabilities. Other developers with asp.net skills to be able to build the application such as application forms, the portal from where users will be able to start the CRM processes, searching capabilities, etc. So might the above point raise some risks when I start hiring a new team and start building the CRM application, OR I am on the right track at this early stage?

• Recommendation for a platform to teach game development to kids [closed]

  - by Moshe Kravchik

  My 11 years old son decided he want to create a Web game. He does not know much about programming and I never did any game development so I'm not the best teacher of the topic. On one hand I really want him to get into building things and doing his own game sounds perfect. So I'd like to find a way to keep him interested and progressing by himself. This means that I'm looking for a platform that is: 1. Simple for understanding and use, intuitive interface 2. Powerful 3. Good tools, preferrably free 4. Significant community for questions and tips 5. Localization - my son's English is quite poor (native Hebrew). We looked at Alice, but it was too limited in its abilities and isn't really a Web game building platform. HTML/CSS and Javascript - too low level for a kid to keep the interest. What would you recommend?

• Development processes, the use of version control, and unit-testing

  - by ct01

  Preface I've worked at quite a few "flat" organizations in my time. Most of the version control policy/process has been "only commit after it's been tested". We were constantly committing at each place to "trunk" (cvs/svn). The same was true with unit-testing - it's always been a "we need to do this" mentality but it never really materializes in a substantive form b/c there is no institutional knowledge base to do it - no mentorship. Version Control The emphasis for version control management at one place was a very strict protocol for commit messages (format & content). The other places let employees just do "whatever". The branching, tagging, committing, rolling back, and merging aspect of things was always ill defined and almost never used. This sort of seems to leave the version control system in the position of being a fancy file-storage mechanism with a meta-data component that never really gets accessed/utilized. (The same was true for unit testing and committing code to the source tree) Unit tests It seems there's a prevailing "we must/should do this" mentality in most places I've worked. As a policy or standard operating procedure it never gets implemented because there seems to be a very ill-defined understanding about what that means, what is going to be tested, and how to do it. Summary It seems most places I've been to think version control and unit testing is "important" b/c the trendy trade journals say it is but, if there's very little mentorship to use these tools or any real business policies, then the full power of version control/unit testing is never really expressed. So grunts, like myself, never really have a complete understanding of the point beyond that "it's a good thing" and "we should do it". Question I was wondering if there are blogs, books, white-papers, or online journals about what one could call the business process or "standard operating procedures" or uses cases for version control and unit testing? I want to know more than the trade journals tell me and get serious about doing these things. PS: @Henrik Hansen had a great comment about the lack of definition for the question. I'm not interested in a specific unit-testing/versioning product or methodology (like, XP) - my interest is more about work-flow at the individual team/developer level than evangelism. This is more-or-less a by product of the management situation I've operated under more than a lack of reading software engineering books or magazines about development processes. A lot of what I've seen/read is more marketing oriented material than any specifically enumerated description of "well, this is how our shop operates".

• Getting into driver development for linux [closed]

  - by user1103966

  Right now, I've been learning about writing device-drivers for linux 3.2 kernel for about 2 months. So far I have been able program simple char drivers that only read and write to a fictitious dev structure like a file, but now I'm moving to more advance concepts. The new material I've learned about includes I/O port manipulation, memory management, and interrupts. I feel that I have a basic understanding of overall driver operation but, there is still so much that I don't know. My question is this, given that I have the basic theory of how to write a dev-driver for a piece of hardware ... how long would it take to actually develop the skills of writing actual software that companies would want to employ? I plan on getting involved in an open-source project and building a portfolio. Also what type of beginner drivers could I write for hardware that would best help me develop my skills? I was thinking that taking on a project where I design my own key logger would easy and a good assignment to help me understand how IO ports and interrupts are used. I may want to eventually specialize in writing software for video cards or network devices though these devices seem beyond my understanding at the moment. Thanks for any help

• Development Environment in a VM against an isolated development/test network

  - by bart

  I currently work in an organization that forces all software development to be done inside a VM. This is for a variety of risk/governance/security/compliance reasons. The standard setup is something like: VMWare image given to devs with tools installed VM is customized to suit project/stream needs VM sits in a network & domain that is isolated from the live/production network SCM connectivity is only possible through dev/test network Email and office tools need to be on live network so this means having two separate desktops going at once Heavyweight dev tools in use on VMs so they are very resource hungry Some problems that people complain about are: Development environment runs slower than normal (host OS is windows XP so memory is limited) Switching between DEV machine and Email/Office machine is a pain, simple things like cut and paste are made harder. This is less efficient from a usability perspective. Mouse in particular doesn't seem to work properly using VMWare player or RDP. Need a separate login to Dev/Test network/domain Has anyone seen or worked in other (hopefully better) setups to this that have similar constraints (as mentioned at the top)? In particular are there viable options that would remove the need for running stuff in a VM altogether?

• Bulk Rename Tool is a Lightweight but Powerful File Renaming Tool

  - by Jason Fitzpatrick

  There’s no need to settle for overly simplistic file renaming tools as long as Bulk Rename Tool is around. It’s lightweight, insanely customizable, portable, and sure to make short work of any renaming task you throw at it. Bulk Rename Tool is a great portable application (available as an installed version if you crave context menu integration) that blasts through file renaming tasks. The main panel is intimidatingly packed with toggles and variables you can alter; this isn’t a one-click solution by any means. That said, once you get comfortable using the interface it’s lightening fast and extremely flexible. One tip that will save you an enormous amount of frustrating when you get started: make sure to highlight the files you want to change in the file preview window (located in the upper right corner) or else you won’t see the preview and won’t know if the changes you’re making in the control panel are yielding the file names you desire. Hit up the link below to read more and grab a copy; Bulk Rename Tool is free, Windows only.

• Is Test Driven Development viable in game development?

  - by Will Marcouiller

  As being Scrum certified, I tend to prone for Agile methodologies while developping a system, and even use some canvas from the Scrum framework to manage my day-to-day work. Besides, I am wondering whether TDD is an option in game development, if it is viable? If I believe this GD question, TDD is not much of a use in game development. Why are MVC & TDD not employed more in game architecture? I come from industrial programming where big projects with big budgets need to work flawlessly, as it could result to catastrophic scenarios if the code wasn't throroughly tested inside and out. Plus, following Scrum rules encourages meeting the due dates of your work while every single action in Scrum is time-boxed! So, I agree when in the question linked above they say to stop trying to build a system, and start writing the game. It is quite what Scrum says, try not to build the perfect system, first: make it work by the Sprint end. Then, refactor the code while working in the second Sprint if needed! I understand that if not all departments responsible for the game development use Scrum, Scrum becomes useless. But let's consider for a moment that all the departments do use Scrum... I think that TDD would be good to write bug-free code, though you do not want to write the "perfect" system/game. So my question is the following: Is TDD viable in game development anyhow?

  I have a problem that my developer friends share. We recently left university and find ourselves either end up working for a firm which already has good procedures (TDD, automated testing, proper agile development, etc) or working for a firm which doesn't. I want to learn some of these vital skills and get a grip on what a complete start-to-finish development procedure would look like. What differences would be between a smaller project, and a long term project with many team members.

• Web Development Trends: Mobile First, Data-Oriented Development, and Single Page Applications

  - by dwahlin

  I recently had the opportunity to give a keynote talk at an Intel conference about key trends in the world of Web development that I feel teams should be taking into account with projects. It was a lot of fun and I had the opportunity to talk with a lot of different people about projects they’re working on. There are a million things that could be covered for this type of talk (HTML5 anyone?) but I only had 60 minutes and couldn’t possibly cover them all so I decided to focus on 3 key areas: mobile, data-oriented development, and SPAs. The talk was geared toward introducing people (many who weren’t Web developers) to topics such as mobile first development (demos showed a few tools to help here), responsive design techniques, data binding techniques that can simplify code, and Single Page Application (SPA) benefits. Links to code demos shown during the presentation can be found at the end of the slide deck. Web Development Trends - What's New in the World of Web Development by Dan Wahlin
