  • How to store wiki sites (vcs)

    - by Eugen
    Hello, as a personal project I am trying to write a wiki with the help of django. I'm a beginner when it comes to web development. I am at the (early) point where I need to decide how to store the wiki sites. I have three approaches in mind and would like to know your suggestion. Flat files I considered a flat file approach with a version control system like git or mercurial. Firstly, I would have some example wikis to look at like http://hatta.sheep.art.pl/. Secondly, the vcs would probably deal with editing conflicts and keeping the edit history, so I would not have to reinvent the wheel. And thirdly, I could probably easily clone the wiki repository, so I (or for that matter others) can have an offline copy of the wiki. On the other hand, as far as I know, I can not use django models with flat files. Then, if I wanted to add fields to a wiki site, like a category, I would need to somehow keep a reference to that flat file in order to associate the fields in the database with the flat file. Besides, I don't know if it is a good idea to have all the wiki sites in one repository. I imagine it is more natural to have kind of like a repository per wiki site resp. file. Last but not least, I'm not sure, but I think using flat files would limit my deploying capabilities because web hosts maybe don't allow creating files (I'm thinking, for example, of Google App Engine) Storing in a database By storing the wiki sites in the database I can utilize django models and associate arbitrary fields with the wiki site. I probably would also have an easier life deploying the wiki. But I would not get vcs features like history and conflict resolving per se. I searched for django-extensions to help me and I found django-reversion. However, I do not fully understand if it fit my needs. Does it track model changes like for example if I change the django model file, or does it track the content of the models (which would fit my need). Plus, I do not see if django reversion would help me with edit conflicts. Storing a vcs repository in a database field This would be my ideal solution. It would combine the advantages of both previous approaches without the disadvantages. That is; I would have vcs features but I would save the wiki sites in a database. The problem is: I have no idea how feasible that is. I just imagine saving a wiki site/source together with a git/mercurial repository in a database field. Yet, I somehow doubt database fields work like that. So, I'm open for any other approaches but this is what I came up with. Also, if you're interested, you can find the crappy early test I'm working on here http://github.com/eugenkiss/instantwiki-test

  • QtCreator on linux: 32-bits vs. 64-bits.

    - by Claire Huang
    My laptop is 64-bits, so when I start to use Qt, I chose 64-bit QtCreator. Now I'm facing a problem, I wish that the executable files I generated are runnnable on 32-bit linux system. Can I set QtCreator to generate 32-bit executable files? So that I can decide I want to generate 32-bit ones or 64-bit ones. I don't want to install another 32-bit QtCreator <.

  • What is the best way to work on a MVC project online?

    - by Alon
    In a regular Web Forms application, I could upload the files to a web server and just open the web server in Visual Web Developer and it worked great, but because MVC is a project and not a web application, I can't just upload the files regulary and still open it in Visual Web Developre normally... So here comes the SVN, but the problem is that I can't show the web site before publish to my boss... Any solutions?

  • How do I minimize the number of changes between revisions with new doxygen output?

    - by Dirk Eddelbuettel
    A subversion repository contains the html, latex and man directories that doxygen generates from the source code. Even for small source code changes, new files are being generated with random names which makes for large changes in the version control system. Is there are way around this? How can I minimize the changesets between revisions while still including doxygen-generated documentation? Alternatively, how could I find which of the doxygen-genrated files are no longer being used and should be removed?

  • Where to document code with Doxygen

    - by Typeoneerror
    Hello. I've never written documentation for any C-style code before (only done asdoc and phpdoc). I've been looking at Doxygen for documenting my Objective-C code, but I'm unsure where to put the comments. Should I document the .h files or should I add the comments to the .m files? or both? Any other recommendations?

  • Is Zend Framework a total waste of my time?

    - by Citizen
    Ok, I'm about 50% done with the "30 minute" quickstart guide from Zend. I must be missing something, because this seems like a total waste of time. The point of this quickguide is to create a guestbook, something I could do in 5 minutes with regular naked non-framework php. Here's my path to zend framework: c:/program files/wamp/www/_zend/ Here's my path to my quickstart project: c:/program files/wamp/www/_zend/bin/quickstart/ I have a number of questions at this point: http://framework.zend.com/docs/quickstart/create-a-model-and-database-table 1: I'm running the command line to run my database loading script. I get an error stating the it can't find the Zend/AutoLoader.php becuase my path to the zend library is wrong. I followed all of the steps. I defined the path to my zend library in the main config file, but for some reason, its defined again in my db loader. In all of these scripts that they have me load, it points the relative path to the zend library as being /../library Problem is, there's nothing in that folder. To get to my actual zend folder, you'd need to be (relatively) /../../../../library Which brings me to my 2nd question: 2: Where the #$#$ is the main Zend files supposed to be? The install directions were basically "put it wherever you want", when the real answer (after a bunch of errors and wasted time was) was "put it somewhere so that its really easy to type the full path a thousand times in command line" and "it also better be in a runnable place on your webserver since its going to create your quickstart application in a subdirectory within zend". Which brings us to the third question 3: Am I supposed to have this libary in both the parent core Zend (wamp/_zend/library) AND my application (quickstart/library)? 4: If that is the case, it seems like a ton of wasted files to be uploading. I'd like to use Zend to create products that my customers will download. 5 megs of overhead seems like a bit much. Zend claims you can use these library components separately, but it looks to me like I'm going to have to upload them every time. Which leads to the next question: 5: It appears that perhaps Zend is more for a single application that is not supposed to be distributed. Is this not the case? 6: According to their default file structure everything but my /public folder would be above public_html on my server if I wanted this to rest on my TLD. I would need to rename every reference of /public/ to /public_html/, or am I missing something else?

  • Make NetBeans automatically include newline at end of file?

    - by keithjgrant
    I just switched to NetBeans (6.8) and have noticed some of my files don't end with a newline. This has been a helpful option in other IDEs I've used, but I haven't been able to find it in the NetBeans options menus. Is it buried in there somewhere or is there any other way to make sure it always saves files with a newline at the end? I'm coding primarily in PHP, if it's available in any of the language-specific options.

  • MS SQL Error: Primary file group is full

    - by aximili
    I have a very large table in my database and I am starting to get this error Could not allocate a new page for database 'mydatabase' because of insufficient disk space in filegroup 'PRIMARY'. Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. How do you fix this error? I don't understand the suggestions there.

  • Javascript source code analysis ( specifically duplication checking )

    - by David
    Partial duplicate of this Notes: I already use JSLint extensively via a tool I wrote that scans in intervals my current project directory for recently updated/created .js files. It's drastically improved productivity for me and I doubt there is anything as good as JSLint for the price (it's free). That said, is there any analysis tool out there that can find repetitive or near-duplicate code blocks, the goal being to make it easier to find opportunities to consolidate large files or small/medium sized projects?

  • Missing AVFoundation.framework

    - by Alex
    Hi, AVFoundation.framework is not where the documentation says it should be. I have iPhone SDK 2.2 installed (never had previous sdk versions installed) and I can't find that folder under /System/Library/Frameworks I did find it under /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.sdk/System/Library/Frameworks/ folder but if I add it from that location, then the compiler can't find the header files. I tried copying the entire AVFoundation.framework folder to /System/Library/Framework, but it still can't find the header files. How can I use AVFoundation classes? Thanks, Alex

  • How to compile libsox with MinGW

    - by kaykun
    Hi, I'm trying to use libsox into another program of mine, but I can't seem to compile libsox with MinGW or find any places with working binaries. I downloaded the source from the official site http://sox.sourceforge.net/ but I don't know which files to include in the project to compile it. I can't compile it with all the files included in the 'src' directory and I think I only need to compile the functions listed here: http://sox.sourceforge.net/libsox.html but I can't seem to find it. Can anyone help?

  • Remove certain filetypes in Python

    - by Gareth
    Hello. I am running a script that walks a directory structure and generates new files in each folder in the directory. I want to delete some of the files right after creation. This is my idea, but it is quite wrong I imagine: directory = os.path.dirname(obj) m = MeshExporterApplication(directory) os.remove(os.path.join(directory,"*.mesh.xml")) How to you put wildcards in a path? I guess not like /home/me/*.txt, but that is what I am trying. Thanks, Gareth

  • Problem getting correct parameters for C# P/Invoke call to C++ dll

    - by Jim Jones
    Trying to Interop a functionality from the Outside In API from Oracle. Have the following function: SCCERR EXOpenExport {VTHDOC hDoc, VTDWORD dwOutputId, VTDWORD dwSpecType, VTLPVOID pSpec, VTDWORD dwFlags, VTSYSPARAM dwReserved, VTLPVOID pCallbackFunc, VTSYSPARAM dwCallbackData, VTLPHEXPORT phExport); From the header files I reduced the parameters to: typedef VTSYSPARAM VTHDOC, VTLPHDOC * typedef DWORD_PTR VTSYSPARAM typedef unsigned long DWORD_PTR typedef unsigned long VTDWORD typedef VTVOID* VTLPVOID #define VTVOID void typedef VTHDOC VTHEXPORT, *VTLPEXPORT These are for 32 bit windows Going through the header files, the example programs, and the documentation I found: 1. That pSpec could be a pointer to a buffer or NULL, so I set it to a IntPtr.Zero (documentation). 2. That dwFlags and dwReserved according to the documentation "Must be set by the developer to 0". 3. That pCallbackFunc can be set to NULL if I don't want to handle callbacks. 4. That the last two are based on structs that I wrote C# wrappers for using the [StructLayout(LayoutKind.Sequential)]. Then instatiated an instance and generated the parameters by first creating a IntPtr with Marshal.AllocHGlobal(Marshal.SizeOf(instance)), then getting the address value which is passed as a uint for dwCallbackData and a IntPtr for phExport. The final parameter list is as follows: 1. phDoc as a IntPtr which was loaded with an address by the DAOpenDocument function called before. 2. dwOutputId as uint set to 1535 which represents FI_JPEGFIF 3. dwSpecType as int set to 2 which represents IOTYPE_ANSIPATH 4. pSpec as an IntPtr.Zero where the output will be written 5. dwFlags as uint set to 0 as directed 6. dwReserved as uint set to 0 as directed 7. pCallbackFunc as IntPtr set to NULL as I will handle results 8. dwCallBackDate as uint the address of a buffer for a struct 9. phExport as IntPtr to another struct buffer still get an undefined error from the API. Meaning that the call returns a 961 which is not defined in any of the header files. In the past I have gotten this when my choice of parameter types are incorrect. I started out using Interop Assistant which was helpful in learning how many of the parameter types get translated. It is however limited by how well I am able to glean the correct native type from the header files. For example the hDoc parameter used in the preceding function was defined as a non-filesytem handle, so attempted to use Marshal to create a handle, then used an IntPtr, and finally it turned out to be an int (actually it was &phDoc used here). So is there a more scientific way of doing this, other than trial and error? Jim
