  • Hiernate's version values in Grails app

    - by xain
    Hi, looking at a database dump file, and I see many records in various tables with their version number set in values other than 0 (even 94 in one case). I understand it has to do with hibernate locking strategy, but my concern is that today is Sunday, and the site has almost no visitors so is: is this normal ? Or is there a known hibernate bug or even some programming malpractice producing this ? Thanks in advance.

  • emacs local version control

    - by aaa
    hello. I am wondering if there is local version control/snapshots for emacs independent of VC? let me clarify: every time I save buffer, I would like to be able to keep track of changes of each save in session. I know I can do something similar with backup files, but they are not automated like VC and a somewhat cumbersome. I have searched Google, but did not find the solution. Perhaps my query string was not good. Thanks

  • Chrome OS : déjà un échec pour le créateur de Gmail et de la devise de Google, l'OS accumule les critiques négatives

    Chrome OS : déjà un échec pour le créateur de Gmail et de la devise de Google L'OS accumule les critiques négatives Les premières critiques sur Chrome OS ne sont pas bonnes. Parmi ces testeurs des premiers laptops équipés de l'OS de Google orienté Cloud, deux voix portent un peu plus que les autres. Celle de Paul Buchheit, créateur de Gmail, et celle de Richard Stallman, le père du GNU. La première constatation polémique, bien qu'elle aille dans le sens de la vision de Google d'un OS totalement intégré dans le Web, a choqué plus d'un testeur de la première heure. Chrome OS n'a tout simplement pas d'explorateur de disques durs. En tout cas rien d'équivalent à Windows...

  • Parallel version of loop not faster than serial version

    - by Il-Bhima
    I'm writing a program in C++ to perform a simulation of particular system. For each timestep, the biggest part of the execution is taking up by a single loop. Fortunately this is embarassingly parallel, so I decided to use Boost Threads to parallelize it (I'm running on a 2 core machine). I would expect at speedup close to 2 times the serial version, since there is no locking. However I am finding that there is no speedup at all. I implemented the parallel version of the loop as follows: Wake up the two threads (they are blocked on a barrier). Each thread then performs the following: Atomically fetch and increment a global counter. Retrieve the particle with that index. Perform the computation on that particle, storing the result in a separate array Wait on a job finished barrier The main thread waits on the job finished barrier. I used this approach since it should provide good load balancing (since each computation may take differing amounts of time). I am really curious as to what could possibly cause this slowdown. I always read that atomic variables are fast, but now I'm starting to wonder whether they have their performance costs. If anybody has some ideas what to look for or any hints I would really appreciate it. I've been bashing my head on it for a week, and profiling has not revealed much.

  • File version maintainence via PHP FTP?

    - by Michael
    Currently I'm working on a "plugin" that will be installed on many different sites and I was wondering on the best way for me to maintain the file version of this "plugin". Here's what I was thinking. Have a "master copy" of the plugin on a server, then connect via FTP to the target sites and upload the copy to their site overwriting whatever files they may have. I was wondering the best way to go about this. The "plugin" will have many different folders and files so transferring one file at a time will be too tedious. Is there a way to copy an entire folder over at a time? Or even better, is there a way to recurse through the folders and checking for file difference before uploading the new file? This is to make sure we are uploading a new file and not just the same one.

  • I want to version control my entire slice

    - by Tom
    I'm renting a slice (i.e., a VPS) from Slicehost. I've a spent a day or two filling up /usr with my favorite packages, /etc with configs and init scripts, and so on. Now I want to: save this whole setup somewhere (e.g., to load onto another machine). see what changes I've made to which files revert changes, tag revisions, and all that other good version control stuff Saving a disk image gives me (1), but not (2) and (3). Using Subversion (svn import / svn://someotherhost) might give me all three, but I expect problems if I actually try to check a project out into / and maintain .svn directories in root-owned areas. And to load my setup onto a fresh slice, I'd need to install an svn client on it first. Is there a good way to do what I want to do?

  • Again, what version control system to choose?

    - by Ivan
    Please excuse me for probably a newbie hundred-times-chewed question. I have no experience with version control systems except of using Visual Source Safe in a project done by 2 people sitting in front of each other (which has shown VSS quite sack of boulders, not anything useful). Right now I am looking to grok-in using some modern VCS. Here are the preferences in descending priority order: Platform-agnostic. Pretty pleasant to use With Visual Studio 2010 on Windows as well as With NetBeans 6.9 and Eclipse 3.6 on Linux and Mac. Convenient and efficient for mutually-dependent projects done by teams of 1-10 and consisting of files of quite a diverse selection of types. Including early-stage projects with unstable design and experimenting. Modern. As fresh and future-technology-feature-rich as possible. Free & open-source. Should I take a closer look at SVN, Mercurial, GIT, Bazaar, or something else?

  • Python 2.6 and 3.1.1, earlier version compatibility

    - by Todd
    I ordered three books to start teaching myself Python - a beginning programming book, a computer science book that uses Python for all of its code references, and a book on Python network programming. Unfortunately, I was a little too quick on ordering them, because I hadn't noticed the version differences. The beginner book is for python 3.1, the CS book is Python 2.3, and the last is Python 2.6. The CS book is also oriented towards beginners. My question is, will the different versions be too different at this level for me to effectively use all three, or will I likely be able to get by learning from the 3.1 beginners book and then sort of teach myself from the 2.3 CS book, and be able to comprehend 2.6 code? That probably didn't make sense. I hope it did.

  • How to get cheap version control?

    - by gotch4
    Hello, I'm a programmer, contractor, self experimenter and so on. I'd need to have cheap version control. I've been working with Subversion and recently with Mercurial. I've seen around many cheap hosting but, even if they are great (like BitBucket), many of them don't allow many private projects (1 or 2). Much of the code I need to keep on VC is not open, maybe because it is stuff I'm working on for clients, or maybe because it's code I usually need for my development, but it is not intended and usable as a open source project. Now, I've a cheap web hosting, with unlimited space and free mysql. I CAN'T install Mercurial or SVN on those machinese, but I was asking myself if is it there a way to use a common CVS with it, with "common" I mean something that has its good IDE plugins (Eclipse or Netbeans) that may avoid me to write commands by hand. Thank you

  • Learning about version control systems, Git, SVN

    - by anijhaw
    I am a basic SVN user now trying to learn GIT for a new position. I am trying the usual reading docs and watching videos. However after doing all that I still feel that there is a lot that I do not know. I was wondering if there is a place like project Euler for programming languages, that provides a series of exercises that you can do just to increase your confidence and test your knowledge about a version control system. Something thats generic enough and gets you up to speed with how to do basic things. This could also serve as a comparison point of sorts between multiple VCSs, that would show what things are easy in which VCS. If there is nothing I was planning to document my journey in learning GIT and the create an exercise of this sort.

  • When to use Version Control?

    - by user156814
    I am a lone developer, developing Web Sites/Apps in PHP. I dont work with anybody, I use a framework so I dont create libraries for my apps (most of the time). I have read a lot about Version Control and its benefits, but I dont understand how it would benefit somebody like me. The biggest benefit I can see it having is that if I posted the code on a remote server I could work from anywhere on any computer, but I carry my laptop like I carry my phone so again I dont see much of a reason there. Can somebody please explain to me in a simple manner the reasons for going with a VCS, and give me some good free ones I should try? Are there any hidden benefits/scenarios that you can think of that may sway me in any direction one way or the other. Thanks

  • How to store static content across branches in a single location in version control

    - by Shravan
    [Just a random thought] I have a pdf doc that is downloaded when the user clicks on 'help' on my website. Now, this is a pretty huge document and is saved in version control (SVN) and is thus copied for all branches that exist in SVN. This is static content and something that developers are not working on, and does not change often. Is there a more efficient way to store it (that would not hamper local deployments) that would make SVN checkouts and updates relatively faster. I know the benefit we get is not huge, this is something that came to my head none the less.

  • Add version control to existing SQL Server database

    - by ederbf
    I am part of a development team currently working with a database that does not have any kind of source control. We work with SQL Server 2008 R2 and have always managed the DB directly with SSMS. It now has ~340 tables and ~1600 stored procedures, plus a few triggers and views, so it is not a small DB. My goal is to have the DB under version control, so I have been reading articles, like Scott Allen's series (http://bitly.com/9cJmGR) and many old SO related questions. But I am still unable to decide on how to proceed. What I'm thinking of is to script the database schema in one file, then procedures, triggers and views in one file each. Then keep everything versioned under Mercurial. But of course, every member of the team can access SSMS and directly change the schema and procedures, with the possibility that any of us can forget to replicate those changes in the versioned files. What better options are there? And, did I forget any element worth having source control of?

  • Renaming files: Visual Studio vs Version control

    - by Benjol
    The problem with renaming files is that if you want to take advantage of Visual Studio refactoring, you really need to do it from inside Visual Studio. But most (not all*) version control system also want to be the ones doing the renaming. One solution is to use integrated source control, but this is not always available, and in some cases is pretty clunky. I'd personally be more comfortable using source control separately, outside of Visual Studio, but I'm not sure how to manage this question of file renames. So, for those of you that use Visual Studio, which source control do you use? Do you use a VS integration (which one?) and otherwise, how do you resolve this renaming problem? (* git is smart enough to work it out for itself)

  • Scalable (half-million files) version control system

    - by hashable
    We use SVN for our source-code revision control and are experimenting using it for non-source-code files. We are working with a large set (300-500k) of short (1-4kB) text files that will be updated on a regular basis and need to version control it. We tried using SVN in flat-file mode and it is struggling to handle the first commit (500k files checked in) taking about 36 hours. On a daily basis, we need the system to be able to handle 10k modified files per commit transaction in a short time (<5 min). My questions: Is SVN the right solution for my purpose. The initial speed seems too slow for practical use. If Yes, is there a particular svn server implementation that is fast? (We are currently using the gnu/linux default svn server and command line client.) If No, what are the best f/oss/commercial alternatives Thanks

  • Proper permission and directoy location for Git Version Control

    - by CitadelCSAlum
    I am using Git Version Control on an remote server and I have set up a repository that multiple people will be using to push/fetch from. I have put the repo under /srv/subdir/git/.git I have been experiencing problem after problem it seems like. a) Is this location suitable for handling a project that will need to be accessed/modified by multiple developers and a designer? Or is there a better location? b)Do I need to modify the permissions on the subdir/ and git/ directories in order to allow remote access? If I do what is the appropriate permissions I should allow? I know this is a faily long request/question, but unfortunately like many other topics with well covered documentation, documentation does not always cover best practices. I would appreciate anybodies advice and suggestions? Thanks

  • version control projects in eclipse

    - by Stan
    Say I have eclipse installed in office and home. Both eclipse are 3.5 but may have slightly difference, like plugins version. I'd like to commit the code to online repo when get off work and then checkout at home. What would be a possible solution? github? sourceforge? Are they free? Would those slightly difference in eclipse cause any problem? Since I might commit whole project folder which consist some configurations. Can the community explain a bit or suggest some keyword? I will look up more online. Thanks.

  • IIS version control with Mac clients

    - by shummel7845
    We are in a unique situation here at work. Most of our websites are on an IIS server, but our developers are on Macs. We need some kind of way to do version control of our websites, but want to manage them locally on our Macs. Is there any way to do this, short of Powershell? Most of our websites are in PHP, so we don't want a solution that is geared toward ASP.NET. Also, I'm not clear if there is a way to use Subversion with IIS. Can someone help me out?
