• Setting up a (web) development environment

  - by mnml

  Hi, I would like to know how I can improve my development environment. At the moment: I'm using Netbeans as my IDE. My local Dev server runs on a RHEL5 VirtualMachine similar to my production server. My Netbeans project is editing the VM files via ssh (I have mounted the server as a local drive) But: It's slow Files can disapear ( netbeans delete them ? ) I can't use git on it because it's slow. The idea would be to be able to have a shared filesytem between the guest os and the host os.

• Vim or Emacs for software development

  - by Justin

  I'm not trying to start any wars here, just get some good info. I'm getting a little exhausted using numerous IDE's for development (VS, XCode, Eclipse/Netbeans, and TextMate) and am looking for a replacement I can use on all the different machines I interact with. What are some of the pros of Vim/Emacs for things like Languages supported Syntax highlighting (for things such as c, objc-c, c#, java, python, haskell, html, javascript, xml etc...) Code completion Code folding Working with a directory of files (like have a solution/project opened) Possible debugger support What are some of the main things you like about (Emacs/Vim, and please no flames only what you really like) Thanks =) *(yes.. I have scoured the net reading this vs that etc. but I'd like more of a 'why you love it' vs 'this is better than that because...')

• In TDD, should tests be written by the person who implemented the feature under test?

  - by martin

  We run a project in which we want to solve with test driven development. I thought about some questions that came up when initiating the project. One question was: Who should write the unit-test for a feature? Should the unit-test be written by the feature-implementing programmer? Or should the unit test be written by another programmer, who defines what a method should do and the feature-implementing programmer implements the method until the tests runs? If I understand the concept of TDD in the right way, the feature-implementing programmer has to write the test by himself, because TDD is procedure with mini-iterations. So it would be too complex to have the tests written by another programmer? What would you say? Should the tests in TDD be written by the programmer himself or should another programmer write the tests that describes what a method can do?

• Event Driven Behavior Tree: deterministic traversal order with parallel

  - by Heisenbug

  I've studied several articles and listen some talks about behavior trees (mostly the resources available on AIGameDev by Alex J. Champandard). I'm particularly interested on event driven behavior trees, but I have still some doubts on how to implement them correctly using a scheduler. Just a quick recap: Standard Behavior Tree Each execution tick the tree is traversed from the root in depth-first order The execution order is implicitly expressed by the tree structure. So in the case of behaviors parented to a parallel node, even if both children are executed during the same traversing, the first leaf is always evaluated first. Event Driven BT During the first traversal the nodes (tasks) are enqueued using a scheduler which is responsible for updating only running ones every update The first traversal implicitly produce a depth-first ordered queue in the scheduler Non leaf nodes stays suspended mostly of the time. When a leaf node terminate(either with success or fail status) the parent (observer) is waked up allowing the tree traversing to continue and new tasks will be enqueued in the scheduler Without parallel nodes in the tree there will be up to 1 task running in the scheduler Without parallel nodes, the tasks in the queue(excluding dynamic priority implementation) will be always ordered in a depth-first order (is this right?) Now, from what is my understanding of a possible implementation, there are 2 requirements I think must be respected(I'm not sure though): Now, some requirements I think needs to be guaranteed by a correct implementation are: The result of the traversing should be independent from which implementation strategy is used. The traversing result must be deterministic. I'm struggling trying to guarantee both in the case of parallel nodes. Here's an example: Parallel_1 -->Sequence_1 ---->leaf_A ---->leaf_B -->leaf_C Considering a FIFO policy of the scheduler, before leaf_A node terminates the tasks in the scheduler are: P1(suspended),S1(suspended),leaf_A(running),leaf_C(running) When leaf_A terminate leaf_B will be scheduled (at the end of the queue), so the queue will become: P1(suspended),S1(suspended),leaf_C(running),leaf_B(running) In this case leaf_B will be executed after leaf_C at every update, meanwhile with a non event-driven traversing from the root node, the leaf_B will always be evaluated before leaf_A. So I have a couple of question: do I have understand correctly how event driven BT work? How can I guarantee the depth first order is respected with such an implementation? is this a common issue or am I missing something?

• Taking a Projects Development to the Next Level

  - by user1745022

  I have been looking for some advice for a while on how to handle a project I am working on, but to no avail. I am pretty much on my fourth iteration of improving an "application" I am working on; the first two times were in Excel, the third Time in Access, and now in Visual Studio. The field is manufacturing. The basic idea is I am taking read-only data from a massive Sybase server, filtering it and creating much smaller tables in Access daily (using delete and append Queries) and then doing a bunch of stuff. More specifically, I use a series of queries to either combine data from multiple tables or group data in specific ways (aggregate functions), and then I place this data into a table (so I can sort and manipulate data using DAO.recordset and run multiple custom algorithms). This process is then repeated multiple times throughout the database until a set of relevant tables are created. Many times I will create a field in a query with a value such as 1.1 so that when I append it to a table I can store information in the field from the algorithms. So as the process continues the number of fields for the tables change. The overall application consists of 4 "back-end" databases linked together on a shared drive, with various output (either front-end access applications or Excel). So my question is is this how many data driven applications that solve problems essentially work? Each backend database is updated with fresh data daily and updating each takes around 10 seconds (for three) and 2 minutes(for 1). Project Objectives. I want/am moving to SQL Server soon. Front End will be a Web Application (I know basic web-development and like the administration flexibility) and visual-studio will be IDE with c#/.NET. Should these algorithms be run "inside the database," or using a series of C# functions on each server request. I know you're not supposed to store data in a database unless it is an actual data point, and in Access I have many columns that just hold calculations from algorithms in vba. The truth is, I have seen multiple professional Access applications, and have never seen one that has the complexity or does even close to what mine does (for better or worse). But I know some professional software applications are 1000 times better then mine. So Please Please Please give me a suggestion of some sort. I have been completely on my own and need some guidance on how to approach this project the right way.

• Web application development platform recommendation

  - by TK.Maxi

  Hi all I did a year's worth of Pascal, Visual Basic and C++ 15 years ago, so suffice it to say that I'm a complete n00b & lamer when it comes to this. I really do hope that this question doesn't canned, but if it does, please be so kind as to point me in the direction of where it should be posted. I have an idea, like so many others, for a web app. I don't necessarily have the capital to outsource the development of the app right now, and I probably wouldn't want to, since non-disclosure agreements can be expensive to enforce, especially in this day and age of intercontinental outsourcing. I need the app to be usable on any mobile device (eventually), primarily on the major mobile platforms at first, on the web, (pc/mac/*ix) obviously, on mobile web browsers like opera mobile, etc. I envisage the app interacting with the major social networks like fb, orkut, msn im, twitter, et al in a way where friend's are messaged and/or wall posted, a message is posted to the users wall. Geo-location functionality is a plus, considering the service/app can be location sensitive in two ways, 1, the immediate location of the user, 2. the desired location of the user. I'd like to incorporate OpenID sign on, and the flip-side, the service will require that people (service providers) list their specialities/specialisations/interests/areas of expertise, so that matches to user requests can be made by the service, while users' requests are posted into the web universe. I've probably described a glut of apps out there, but I'd appreciate feedback on the sort of platform that I should look at using, be it hosted on something like Google's app engine, or written in android friendly code, or whatever. I'm a firm believer in herd mentality, especially at the start of a project that I have very little experience in. The more opinions, the merrier! I can't get very much more specific, since that would give the idea away. Thanks for your time and I look forward to hearing from wise and experienced and the fresh and innovative alike. Thanks

• How to maintain base files for development environment central while allowing people to change their

  - by Ittai

  Hi, what I'd like to do is have files in a central location so that when I add people to my development team they can see the base version of these files but meanwhile have the ability for the rest of the team to work with their own local version. I know I can just put the files in source-control (we use Tortoiese-SVN) and have my team change the local versions but I'd rather not as the exclamation mark signaling the file has been changed and needs to be committed, quite frankly, irritates me greatly. I'll give two examples of what I mean: We use quite a few build.xml files which relate to a single properties files which contains many definitions. Some of them can be different between team-members (mainly temporary working directories) and I'd like a new team-member to have the ability to get the properties file with the base config but change it if they wish. Have the eclipse settings file in the SVN so that when a new team-member joins they can just retrieve the files from the server and have a base system running. If they wish they will be able to change some of these settings. Thanks, Ittai

  I am on summer vacation, but I want to learn web development, The current programming language I know are the following C# Java C and I know the following scripting and markup language Javascript HTML and a little bit of PHP. but I wanted to know where would I learn most? should I venture on PHP? or Ruby on Rails? I don't have any experience or knowledge with regards to Ruby and of course ruby on rails, but I am gussing Ruby is a pre-requisite for learning the Ruby on rails framework right? Now the question, WHat are the pros and cons of both these language, is ruby worth learning just for Ruby on rails? and which has a higher market?

• How can a web developer contribute to Ubuntu?

  - by Kyle Macey

  I've done web development for the past ten years, and have used Ubuntu for my operating system for the past five. I feel like my design and development skills could be useful, but don't know how I can help with experience in web development. I'm currently versed in Ruby, PHP, ColdFusion, and Javascript, and I took a Java class in college. I'm also willing to learn a new language, but don't even know where to start as far as what would be most helpful to the Ubuntu community. Are there projects that a web developer could help with in Ubuntu? Or what language should I learn to best help contribute?

• 'Development dashboard' web application

  - by espais

  Hi all, I am not sure if something like this exists in that it is ready out of the box. I currently have some web space that I use for various projects, and I would like to setup an area for some friends and I to develop web applications together. My ideal setup would be to create a folder, say, webdev.domain.com. We could all go to this domain, login, and then be able to setup new applications, pick which language will be used, setup database tables, allow HTML based file uploading, and create sub-folders to basically have a test bed for the applications. In retrospect, it seems like I'm describing a limited version of cpanel. I could come up with something in Drupal I'm sure, but I don't want to have to really spend time configuring much. Like I said, I want to install it and have minimal configuration. Does something like this exist (preferably in open-source)?

• Web Development Law/Ownership of Website

  - by Jackson Buddingh

  I'm a budding web developer, and I wondered if it was illegal to edit a website for a client to include a link that says 'encourage the owner of this site to pay their web developer' and follows up with a pre-made email encouraging the man to pay me. Here are the conditions: I've completed the work for the contract. I've asked to be paid, and tried to set up meetings with the owner. I've informed the owner of the site that my work will not continue unless I am paid. I should have been paid nearly a month ago (12/27) Any thoughts other than small claims? This is my first web-development job!

• Which software development methodologies can be seen as foundations

  - by Bas

  I'm writing a small research paper which involves software development methodologiess. I was looking into all the available methodology's and I was wondering, from all methodologies, are there any that have provided the foundations for the others? For an example, looking at the following methodologies: Agile, Prototyping, Cleanroom, Iterative, RAD, RUP, Spiral, Waterfall, XP, Lean, Scrum, V-Model, TDD. Can we say that: Prototyping, Iterative, Spiral and Waterfall are the "foundation" for the others? Or is there no such thing as "foundations" and does each methodology has it's own unique history? I would ofcourse like to describe all the methodology's in my research paper, but I simply don't have the time to do so and that is why I would like to know which methodologies can be seen as representatives.

• Tips/Process for web-development using Django in a small team

  - by Mridang Agarwalla

  We're developing a web app uing Django and we're a small team of 3-4 programmers — some doing the UI stuff and some doing the Backend stuff. I'd love some tips and suggestions from the people here. This is out current setup: We're using Git as as our SCM tool and following this branching model. We're following the PEP8 for your style guide. Agile is our software development methodology and we're using Jira for that. We're using the Confluence plugin for Jira for documentation and I'm going to be writing a script that also dumps the PyDocs into Confluence. We're using virtualenv for sandboxing We're using zc.buildout for building This is whatever I can think of off the top of my head. Any other suggestions/tips would be welcome. I feel that we have a pretty good set up but I'm also confident that we could do more. Thanks.

• DNS slowdowns on development environment

  - by Sequenzia

  I have a local development environment setup on my Mac. I am running an Ubuntu Web Server inside of a Virtual Box VM. I setup a host file on my Mac that points my dev site to the IP of the Ubuntu Virtual Server. Everything works good other than the fact a lot (not all) of the time it takes more than 5 seconds to load a page. I used firebug to track down where the problem is and when it's slow the DNS part of my request is taking over 5 seconds. Like I said it's not all the time. Sometimes it resolves and loads the page within milliseconds. The same page one click will be super fast and then the next time it takes over 5 seconds. It's really slowing me down and I am not sure what is causing it. Anyone have any ideas? Any help would be great. Thank

• Website development from scratch v/s web framework [duplicate]

  - by Ali

  This question already has an answer here: What should every programmer know about web development? 1 answer Do people develop websites from scratch when there are no particular requirements or they just pick up an existing web framework like Drupal, Joomla, WordPress, etc. The requirements are almost similar in most cases; if personal, it will be a blog or image gallery; if corporate, it will be information pages that can be updated dynamically along with news section. And similarly, there are other requirements which can be fulfilled by WordPress, Joomla or Drupal. So, Is it advisable to develop a website from scratch and why ? Update: to explain more as got commentt from @Raynos (thanks for comment and helping me clearify the question), the question is about: Should web sites be developed and designed fully from scratch? Should they be done by using framework like Spring, Zend, CakePHP? Should they be done using CMS like Joomla, WordPress, Drupal (people in east are using these as frameworks)?

• Web application Project management methodologie

  - by dutchiexl

  I am looking to streamline my company's web development process. Including analysis. I myself am specialized in XP and Scrum. But we are building web application with a process cycle of 3-4 weeks and a lifetime of 1-4 months. When a project is sold, only then the project managers (= people who do analysis but know nothing about it = a small flow chart and some screen shots as analysis) What is happening is: A LOT of change requests Minimal development time Minimal analysis time NOW: the main question :) can you recommend me some methodologies and books to read for the entire project management ? Thanks in advance @Edit, I myself was looking at a combination of SCRUM for the management with flowcharts, + RAD/LD for development, and trying to distilate something from that.

• Moving from local machine to group web development environment

  - by Djave

  I'm a freelancer who currently creates websites locally using something like MAMP to test websites locally before pushing them live with FTP. I'm looking at taking on my first employee, and I would need to be able to work on websites with them simultaneously. Can anyone explain or provide links to some good documentation on team workflow, or some key phrases I should be googling to get started on my set up? Unlike a lot of the stackoverflow community I've never worked in a dev team, large or small as I'm self taught so just need to know where to start. At present I'm thinking I need an extra computer to use as a server, then use Git or some such to version control files on that computer, as well as installing apache on it so it can be viewed by any computers in my current home network. Is this heading down the right track?

• Development on Terminal or IDE [on hold]

  - by Taylor Flores

  I've been using nano, make, gcc, and gdb for 6 months now and I've found it much easier than using VS or Codeblocks. But I'm wondering now: Is development on a terminal more/less efficient that using an IDE? In what situations is one preferred more sensible than the other? I'm not asking about opinions, I want to know if there's specific reasons to use one over the other. From what I can gather: terminals can be used on environments where a GUI is not available terminal projects can be created and configured more quickly IDEs contain better syntax highlighters (ie identity highlighters) This question is C biased, but I think it's relevant to other languages as well.

• Web development tools/approaches?

  - by Clinton

  My day job involves a bit of programming, but I've recently been attempting some web development for personal reasons. I've got Drupal up and running and done basic things like add new content (i.e. heading and text) and add modules and themes, but I'm not sure how to approach actually designing pages. When I mucked around with webpages 15 years ago, it was just a mixture of HTML, CSS and Javascript, generally written with a text editor. Have things changed, or is this the way I'd make a Drupal page today? If it makes a difference, in my case the page's I want to design simply have static content, but I'd like them to be easily updatable.

• How important are unit tests in software development?

  - by Lo Wai Lun

  We are doing software testing by testing a lot of I/O cases, so developers and system analysts can open reviews and test for their committed code within a given time period (e.g. 1 week). But when it come across with extracting information from a database, how to consider the cases and the corresponding methodology to start with? Although that is more likely to be a case studies because the unit-testing depends on the project we have involved which is too specific and particular most of the time. What is the general overview of the steps and precautions for unit-testing?

• Flaws in my PHP development setup - sharing sources causing lags

  - by Wiktor

  I have following development setup for my PHP projects: Working station running on Windows 7 with PhpStorm IDE. GIT for version controlling. CentOS on virtual machine (VirtualBox) with Apache and MySQL (copy of production server). So far, I've been sharing project's source folders between host and guest systems and it was working quite well only really slow. The reason behind this is that Apache was reading files from remote folder (mounted locally). After doing some research, I found out that this set up can be improved by using disk mapping (Samba) instead of folder sharing. So I did that change. I configured my PhpStorm to automatically deploy files to mapped drive. Everything works like a charm now, except for one problem - when I change branches I need to synchronize project's local folder with the one on mapped drive and that takes time, a lot of time (like branching in SVN). Is there another way to handle this than just working on files directly on mapped drive?

• Splitting up revenue among development team members on Apple's app store

  - by itaiferber

  A friend and I have started developing an app to put on Apple's app store. Development is going fine, but thinking ahead, we're trying to come up with an easy way to share any revenue coming from our efforts. The app store allows you to deposit your revenue into a single bank account, but there's no easy way to split revenue among several people. How do (small) dev teams split up revenue on their products, on, and off the app store? As far as I can tell, banks don't offer an easy way to automatically split the balance on an account 50-50 (or any other percentage, for that matter), especially on a regular basis. So how do teams deal with this? We're not incorporated, and we don't have an official business set up. We're considering depositing all the money into one of our accounts and manually transferring half the money to the other person, but this isn't sustainable over long periods of time. Is there a low-cost, sustainable, automatic process for handling these finances?
