• On improving commit practices

  - by greengit

  I was thinking about ways to improving my commit practices. Is there any co-relation between no. of source code lines and no. of commits? In a recent project that I was involved in, I was going at 30 commits per 1000 lines. One typical file from the project has these stats language: JavaScript total commits that include this file: 32 total lines: 1408 source lines: 1140 comment lines: 98 no. of function declarations: 28 other declarations: 8 Another file has these... Language: Python total commits that include this file: 17 total lines: 933 source lines: 730 comment lines: 80 classes: 1 methods: 10 I also think that no. of commits is more related to no. of features or no. of changes to the code and less to the no. of lines. The general git community motto is make short commits and commit often. So, do you really think about you commit strategy before you start the project. For that matter, is there anything like commit strategy? If so, what's yours?

• 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?

• Are there any subversion "dash board" web applications that can show me a list of recent commits from all my repositories?

  - by Joe

  I am looking for something like a subversion dashboard that at the very least can show me commits from across a group of repositories. Is there anything like this available? Since it could just as well be dead simple and I can't find anything immediately I am thinking if just scratching my own itch here, but I am hoping someone has wanted this before? Are there any subversion "dashboards" that an show me even a simple twitter-like list of commits from across my repositories?

• User roles in GWT applications

  - by csaffi

  Hi everybody, I'm wondering if you could suggest me any way to implement "user roles" in GWT applications. I would like to implement a GWT application where users log in and are assigned "roles". Based on their role, they would be able to see and use different application areas. Here are two possible solution I thought: 1) A possible solution could be to make an RPC call to the server during onModuleLoad. This RPC call would generate the necessary Widgets and/or place them on a panel and then return this panel to the client end. 2) Another possible solution could be to make an RPC call on login retrieving from server users roles and inspecting them to see what the user can do. What do you think about? Thank you very much in advance for your help!

  - by gsusx

  It’s been a great start of 2011. Tellago’s Dwight Goins has been awarded as a Microsoft BizTalk Server MVP for 2011. I’ve always said that Dwight should have been an MVP a long time ago. His contributions to the BizTalk Server community are nothing but remarkable. In addition to Dwight, my colleagues Don Demsak and Chris Love also renewed their respective MVP award. A few other of us are up for renewal later in the year. As a recognition to Dwight’s award, we have made him the designated doorman...(read more)

• Connect ViewModel and View using Unity

  - by brainbox

  In this post i want to describe the approach of connecting View and ViewModel which I'm using in my last project.The main idea is to do it during resolve inside of unity container. It can be achived using InjectionFactory introduced in Unity 2.0 public static class MVVMUnityExtensions{    public static void RegisterView<TView, TViewModel>(this IUnityContainer container) where TView : FrameworkElement    {        container.RegisterView<TView, TView, TViewModel>();    }    public static void RegisterView<TViewFrom, TViewTo, TViewModel>(this IUnityContainer container)        where TViewTo : FrameworkElement, TViewFrom    {        container.RegisterType<TViewFrom>(new InjectionFactory(            c =>            {                var model = c.Resolve<TViewModel>();                var view = Activator.CreateInstance<TViewTo>();                view.DataContext = model;                return view;            }         ));    }}}And here is the sample how it could be used:var unityContainer = new UnityContainer();unityContainer.RegisterView<IFooView, FooView, FooViewModel>();IFooView view = unityContainer.Resolve<IFooView>(); // view with injected viewmodel in its datacontextPlease tell me your prefered way to connect viewmodel and view.

• git tagging comments - best practices

  - by Evan

  I've adopted a tagging system of x.x.x.x, and this works fine. However, you also need to leave a comment with your git tag. I've been using descriptions such as "fixes bug Y" or "feature X", but is this the best sort of comment to be leaving? Particularly, what if a tag encompasses several fixes, it seems not to make sense to have a very long tag comment. Does this mean that I should be creating a tag for every bug fix or feature, or should the tag comments be reflective of something else? I have a few ideas that may be good, but I'd love some advice from seasoned git tagging veterans :) For those who prefer specific examples: 1.0.0.0 - initial release 1.0.0.1 - bug fix for issue X 1.0.0.2 - (what if this is a bug fix for multiple issues, the comment would be too long, no?) Another example, in this example, the comments are more or less the same as the tags, it seems redundant. Is there something else we could be describing? https://github.com/osCommerce/oscommerce2/tags

• Are `break` and `continue` bad programming practices?

  - by Mikhail

  My boss keeps mentioning nonchalantly that bad programmers use break and continue in loops. I use them all the time because they make sense; let me show you the inspiration: function verify(object) { if (object->value < 0) return false; if (object->value > object->max_value) return false; if (object->name == "") return false; ... } The point here is that first the function checks that the conditions are correct, then executes the actual functionality. IMO same applies with loops: while (primary_condition) { if (loop_count > 1000) break; if (time_exect > 3600) break; if (this->data == "undefined") continue; if (this->skip == true) continue; ... } I think this makes it easier to read & debug; but I also don't see a downside. Please comment.

• Online Accounts auth over and over again without success

  - by Mike Pretzlaw

  I just added my Google account to the "Online Accounts" in Gnome. Before my last restart the account couldn't be added for unknown reason. I authorized Gnome access to my Google Account, the window closed and nothing happened. Now I authorized Ubuntu access to my Google Account which worked well: But I can not open the Gnome Online Accounts even when I delete every online account: It's icon show up that it is loading in the dash but then suddenly disappears without any message. How to debug that? What can I do?

• Time based movement Vs Frame rate based movement?

  - by sil3nt

  Hello there, I'm new to Game programmming and SDL, and I have been following Lazyfoo's SDL tutorials. My question is related to time based motion and frame rate based motion, basically which is better or appropriate depending on situations?. Could you give me an example where each of these methods are used?. Another question I have is that, in lazyfoo's two Motion tutorials (FPS based and time based) The time based method showed a much smoother animation while the Frame rate based one was a little hiccupy, meaning you could clearly see the gap between the previous location of the dot and its current position when you compare the two programs. As beginner which method should I stick to?(all I want is smooth animations).

• Git branching and tagging best practices

  - by Code-Guru

  I am currently learning to use Git by reading Pro Git. Right now I'm learning about branching and tags. My question is when should I use a branch and when should I use a tag? For example, say I create a branch for version 1.1 of a project. When I finish and release this version, should I leave the branch to mark the release version? Or should I add a tag? If I add a tag, should I delete the version branch (assuming that it is merged into master or some other branch)?

• Comparing a saved movement with other movement with Kinect

  - by Ewerton

  I need to develop an application where a user (physiotherapist) will perform a movement in front of the Kinect, I'll write the data movement in the database and then the patient will try to imitate this motion. The system will calculate the similarity between the movement recorded and executed. My first idea is, during recording (each 5 second, by example), to store the position (x, y, z) of the points and then compare them in the execution time(by patient). I know that this approach is too simple, because I imagine that in people of different sizes the skeleton is recognized differently, so the comparison is not reliable. My question is about the best way to compare a saved motion with a movement executed (on the fly). PS: Sorry by my English.

• Examples of continuous integration workflow using git

  - by Andrew Barinov

  Can anyone provide a rough outline of their git workflow that complies with continuous integration. E.g. How do you branch? Do you fast forward commits to the master branch? I am primarily working with Rails as well as client and server side Javascript. If anyone can recommend a solid CI technology that's compatible with those, that'd be great. I've looked into Jenkins but would like to check out other good alternatives. To put some context into this, I am planning on transitioning from working as a single developer into working as part of the team. I'd like to start standardizing my own personal workflow so that I can onboard new devs quickly.

• How can I merge two SubVersion branches to one working copy without committing?

  - by Eric Belair

  My current SubVersion workflow is like so: The trunk is used to make small content changes and bug fixes to the main source code. Branches are used for adding/editing enhancements and projects. So, trunk changes are made, tested, committed and deployed pretty quickly. Whereas, enhancements and projects need additional user testing and approval. At time, I have two branches that need testing and approval at the same time. I don't want to merge to the trunk and commit until the changes are fully tested and approved. What I need to do is merge both branches to one working copy without any commits. I am using Tortoise SVN, and when I try to merge the second branch, I get an error message: Cannot merge into a working copy that has local modifications Is there a way that I can do this without committing either merge?

• Bump version before kicking off new development or when tagging a release, which is better?

  - by linquize

  Some projects bump version before kicking off a new development, while the other projects bump version when tagging a release. Which approach is better? If version number not changed at the start of new phase, the developers may forget to change it and simply release the program. If version number changed before tagging release, then 2 the version numbers (tag and Makefile/AssemblyInfo.cs) do not match. git describe may give you v1.2.3.4-15-g1234567 if current revision is after v1.2.3.4, but you have already changed the files to have v1.2.3.5

• TortoiseSVN post-commit.bat doesn't work [migrated]

  - by user565739

  I am using TortoiseSVN on Windows 7 x64. I tried to put a post-commit.bat in the hooks folder of a repository, but it doesn't work at all. So I tried to put a pre-commit.bat (the content is exact the same as post-commit.bat) in hooks, and it worked fine. This is very strange. The .bat file is very simple, I just tried with: @echo off setlocal set REPOS=%1 set TXN=%2 xcopy C:\a C:\b\ /S /F exit 0 Anyone makes post-commit work with TortoiseSVN?

• Are there advantages to using a DVCS for a solo developer?

  - by SnOrfus

  Right now, I use visual svn on my server, and have ankhsvn/tortoise on my personal machine. It works fine enough, and I don't have to change, but if I can see some benefits of using a DVCS, then I might give it a go. However, if there's no point or difference using it without other people, then I won't bother. So again, I ask, are there any benefits to using a DVCS when you're the only developer?

• How to implement early exit / return in Haskell?

  - by Giorgio

  I am porting a Java application to Haskell. The main method of the Java application follows the pattern: public static void main(String [] args) { if (args.length == 0) { System.out.println("Invalid number of arguments."); System.exit(1); } SomeDataType d = getData(arg[0]); if (!dataOk(d)) { System.out.println("Could not read input data."); System.exit(1); } SomeDataType r = processData(d); if (!resultOk(r)) { System.out.println("Processing failed."); System.exit(1); } ... } So I have different steps and after each step I can either exit with an error code, or continue to the following step. My attempt at porting this to Haskell goes as follows: main :: IO () main = do a <- getArgs if ((length args) == 0) then do putStrLn "Invalid number of arguments." exitWith (ExitFailure 1) else do -- The rest of the main function goes here. With this solution, I will have lots of nested if-then-else (one for each exit point of the original Java code). Is there a more elegant / idiomatic way of implementing this pattern in Haskell? In general, what is a Haskell idiomatic way to implement an early exit / return as used in an imperative language like Java?

• Simultaneous remote connections

  - by user3215

  Is there any package for Ubuntu which allows me to connect to remote computer without disturbing or terminating others who have already connected to that server or who are accessing the computer directly?. I remember I did this in Windows Server 2003 installing Terminal Server when I was doing my course which allowed multiple clients to connect to the server simultaneously with no disturbance to clients and even direct access to server. Is there any package like this for Ubuntu desktops?

• How can I adjust system volume from within XBMC?

  - by d3vid

  While running XBMC, I can adjust the volume of the XBMC application itself. However, this volume is limited by the current system volume. For example, if the system volume is at 80% and XBMC is at 100%, I am effectively at 80% and cannot go higher. Or if the sound is too soft and needs a boost, I would normally increase the system volume beyond 100%. XBMC takes over the whole screen, so the system volume is not accessible. Pressing the Super key brings up the dash and top menu, but clicking on it is difficult and inconsistent, and very quickly XBMC takes over the screen again. How can I adjust the system volume without having to quit XBMC?

• Github Organization Repositories, Issues, Multiple Developers, and Forking - Best Workflow Practices

  - by Jim Rubenstein

  A weird title, yes, but I've got a bit of ground to cover I think. We have an organization account on github with private repositories. We want to use github's native issues/pull-requests features (pull requests are basically exactly what we want as far as code reviews and feature discussions). We found the tool hub by defunkt which has a cool little feature of being able to convert an existing issue to a pull request, and automatically associate your current branch with it. I'm wondering if it is best practice to have each developer in the organization fork the organization's repository to do their feature work/bug fixes/etc. This seems like a pretty solid work flow (as, it's basically what every open source project on github does) but we want to be sure that we can track issues and pull requests from ONE source, the organization's repository. So I have a few questions: Is a fork-per-developer approach appropriate in this case? It seems like it could be a little overkill. I'm not sure that we need a fork for every developer, unless we introduce developers who don't have direct push access and need all their code reviewed. In which case, we would want to institute a policy like that, for those developers only. So, which is better? All developers in a single repository, or a fork for everyone? Does anyone have experience with the hub tool, specifically the pull-request feature? If we do a fork-per-developer (or even for less-privileged devs) will the pull-request feature of hub operate on the pull requests from the upstream master repository (the organization's repository?) or does it have different behavior? EDIT I did some testing with issues, forks, and pull requests and found that. If you create an issue on your organization's repository, then fork the repository from your organization to your own github account, do some changes, merge to your fork's master branch. When you try to run hub -i <issue #> you get an error, User is not authorized to modify the issue. So, apparently that work flow won't work.
