  • How to Compile Mod_Python 3.3.1 for Python 2.6 and Apache 2.2 on Windows?

    - by John
    I have no experience compiling code other than using Visual Studio's Build command. I am hoping we can create a step by step guide for compiling mod_python on windows. Please be as descriptive as possible. This is what I've done so far: Download and install python 2.6.2 Download and install apache 2.2.11 Download the most recent source code for mod_python from svn From here I'm lost to what the next step is. I've downloaded Microsoft Visual C++ 2008 Express Edition. As mentioned by Hao I've already tried the tutorial mentioned in that link. Here is the error messages I'm receiving with that tutorial. C:\mod_python\distbuild_installer.bat Could Not Find C:\mod_python\src*.obj running bdist_wininst running build running build_py creating build creating build\lib.win32-2.6 creating build\lib.win32-2.6\mod_python copying C:\mod_python\lib\python\mod_python\apache.py - build\lib.win32-2.6\mod _python copying C:\mod_python\lib\python\mod_python\cache.py - build\lib.win32-2.6\mod_ python copying C:\mod_python\lib\python\mod_python\cgihandler.py - build\lib.win32-2.6 \mod_python copying C:\mod_python\lib\python\mod_python\Cookie.py - build\lib.win32-2.6\mod _python copying C:\mod_python\lib\python\mod_python\importer.py - build\lib.win32-2.6\m od_python copying C:\mod_python\lib\python\mod_python\psp.py - build\lib.win32-2.6\mod_py thon copying C:\mod_python\lib\python\mod_python\publisher.py - build\lib.win32-2.6\ mod_python copying C:\mod_python\lib\python\mod_python\python22.py - build\lib.win32-2.6\m od_python copying C:\mod_python\lib\python\mod_python\Session.py - build\lib.win32-2.6\mo d_python copying C:\mod_python\lib\python\mod_python\testhandler.py - build\lib.win32-2. 6\mod_python copying C:\mod_python\lib\python\mod_python\util.py - build\lib.win32-2.6\mod_p ython copying C:\mod_python\lib\python\mod_python__init__.py - build\lib.win32-2.6\m od_python running build_ext building 'mod_python_so' extension creating build\temp.win32-2.6 creating build\temp.win32-2.6\Release creating build\temp.win32-2.6\Release\mod_python creating build\temp.win32-2.6\Release\mod_python\src C:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\cl.exe /c /nologo /Ox /MD /W 3 /GS- /DNDEBUG -DWIN32 -DNDEBUG -D_WINDOWS -IC:\mod_python\src\include -Ic:\apa che\include -IC:\Python26\include -IC:\Python26\PC /TcC:\mod_python\src\mod_pyth on.c /Fobuild\temp.win32-2.6\Release\mod_python\src\mod_python.obj mod_python.c c:\apache\include\ap_config.h(25) : fatal error C1083: Cannot open include file: 'apr.h': No such file or directory error: command '"C:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\cl.exe"' fa iled with exit status 2

  • What to send to server in real time FPS game?

    - by syloc
    What is the right way to tell the position of our local player to the server? Some documents say that it is better to send the inputs whenever they are produced. And some documents say the client sends its position in a fixed interval. With the sending the inputs approach: What should I do if the player is holding down the direction keys? It means I need to send a package to the server in every frame. Isn't it too much? And there is also the rotation of the player from the mouse input. Here is an example: http://www.gabrielgambetta.com/fpm_live.html What about sending the position in fixed interval approach. It sends too few messages to the server. But it also reduces responsiveness. So which way is better?

  • Design patter to keep track UITableView rows correspondance to underlying data in constant time.

    - by DenNukem
    When my model changes I want to animate changes in UITableView by inserting/deleting rows. For that I need to know the ordinal of the given row (so I can construct NSIndexPath), which I find hard to do in better-than-linear time. For example, consider that I have a list of addressbook entries which are manualy sorted by the user, i.e. there is no ordering "key" that represents the sort order. There is also a corresponding UITableView that shows one row per addressbook entry. When UITableView queries the datasource I query the NSMUtableArray populated with my entries and return required data in constant time for each row. However, if there is a change in underlying model I am getting a notification "Joe Smith, id#123 has been removed". Now I have a dilemma. A naive approach would be to scan the array, determine the index at which Joe Smith is and then ask UITableView to remove that precise row from the view, also removing it form the array. However, the scan will take linear time to finish. Now I could have an NSDictionary which allows me to find Joe Smith in constant time, but that doesn't do me a lot of good because I still need to find his ordinal index within the array in order to instruct UITableView to remove that row, which is again a linear search. I could further decide to store each object's ordinal inside the object itself to make it constant, but it will become outdated after first such update as all subsequent index values will have changed due to removal of an object. So what is the correct design pattern to accurately reflect model changes in the UITableView in costant (or at least logarithmic) time?

  • How to compile and build C# projects with Ant and Mono?

    - by Wing C. Chen
    I am currently working on a project with both java and C# codes within. Java takes the major role in this project. However, C# still takes a small part in it. I am using Ant to build the projects, and would very much like to use it to build C# too. I have learned that it's possible to build C# under Ant with the help of Mono. Can anybody provide any link of tutorial or guidance here? I was trying to google for it. But I haven't found any comprehensive data.

  • Do I need to compile my solution with VS2010 in order to benefit from .NET 4.0 new Code Access Secur

    - by leo
    Hello, I currently develop an application in C# with framework .NET 3.5 SP1. In my app, I have satellite assemblies which are not in the same folder as the exe, and that causes me some trouble with FullTrust, as explained here. In order to solve that problem, I wish to use .NET 4.0 whose Code Access Security Policy should allow my satellite assemblies to be FullyTrusted. So my question is: is just installing the framework enough, or do I need to rebuild the solution with VS2010? Thanks

  • How can I create a fast, real-time, fixed length glowing ray?

    - by igf
    Similar to the disintegrate skill in Diablo 3. It should not light other objects in scene. Just glowing and animated. Like in this video http://www.youtube.com/watch?v=D_c4x6aQAG8. Should I use pack of pre-computed glow sources textures for each frame of ray animation like in this article http://http.developer.nvidia.com/GPUGems/gpugems_ch21.html and put it in bloom shader? Is there any other efficient ways to achive this effect? I'm using OpenGL ES 2.0.

  • Will I have an easier time learning OpenGL in Pygame or Pyglet? (NeHe tutorials downloaded)

    - by shadowprotocol
    I'm looking between PyGame and Pyglet, Pyglet seems to be somewhat newer and more Pythony, but it's last release according to Wikipedia is January '10. PyGame seems to have more documentation, more recent updates, and more published books/tutorials on the web for learning. I downloaded both the Pyglet and PyGame versions of the NeHe OpenGL tutorials (Lessons 1-10) which cover this material: lesson01 - Setting up the window lesson02 - Polygons lesson03 - Adding color lesson04 - Rotation lesson05 - 3D lesson06 - Textures lesson07 - Filters, Lighting, input lesson08 - Blending (transparency) lesson09 - 2D Sprites in 3D lesson10 - Moving in a 3D world What do you guys think? Is my hunch that I'll be better off working with PyGame somewhat warranted?

  • Why user control with code behind file doesn't want to compile under MVC2?

    - by kyrisu
    I have user control in my MVC2 app placed in the Content folder (it's not supposed to be a view, just reusable part of the app). UserControl1.ascx looks like: <@ Control AutoEventWireup="true" Language="C#" CodeFile="~/Content/UserControl1.ascx.cs" Inherits="MVCDrill.Content.UserControl1" %> <div runat="server" id="mydiv"> <asp:LinkButton id="lb_text" runat="server"></asp:LinkButton> </div> UserControl1.ascx.cs looks like: using System; using System.Web; using System.Web.UI; namespace MVCDrill.Content { public class UserControl1 : UserControl { public string Text { get { return this.lb_text.Text; } set { this.lb_text.Text = value; } } } } I'm pretty sure this kind of stuff compiled under webforms but I'm getting compilation error: 'MVCDrill.Content.UserControl1' does not contain a definition for 'lb_text' and no extension method 'lb_text' accepting a first argument of type 'MVCDrill.Content.UserControl1' could be found (are you missing a using directive or an assembly reference?) Am I missing something? How to change it (what is the alternative) in MVC2 ? p.s. Intellisense sees lb_text with no problem. I've tried with different controls with the same outcome.

  • A good way in .NET Winforms to have user entered time frame?

    - by Ben
    Hi, Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using winforms controls? At the moment I have two numeric up downs, one for time and one for minutes that I then parse to create a timespan. The only other idea I have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though. Any ideas? Thanks

  • How to compile a C DLL for 64 bit with Visual Studio 2010?

    - by Daren Thomas
    I have a DLL written in C in source code. This is the code for the General Polygon Clipper (in case you are interested). I'm using it in a C# project via the C# wrapper provided on the homepage. This comes with a precompiled DLL. Since switching to a 64bit Development machine with Visual Studio 2010 and Windows 7 64 bit, the application won't run anymore. This is the error I get: An attempt was made to load a program with an incorrect format. This is because of DLLImporting the 32bit gpc.dll, as I have gathered from stuff found on the web. I assume this will all go away if I recompile the DLL to 64bit, but can't for the love of me figure out how to do so. My C skills are basic, in that I can write a C program with the GNU tools, but have no experience with various compilers / processors / IDEs etc. I believe I could port this to C#. By that I mean I trust myself to actually pull it off. But I'd prefer not to, since it is a lot of work that I'd prefer a compiler to do for me ;)

  • Compile Error: Ticks must be between DateTime.MinValue.Ticks and DateTime.MaxValue.Ticks. Parameter

    - by mickyjtwin
    I have a Visual Studio 2008 solution that when I build, returns the following error: Ticks must be between DateTime.MinValue.Ticks and DateTime.MaxValue.Ticks. Parameter name: ticks There is no reference file/line/column in the error. Becoming quite frustrating as the solution builds in the end, however I cannot debug. In the solution, there is no reference/using to DateTime.MinValue.Ticks at all...

  • In Jetty, can NCSARequestLog be configured to auto-detect the time zone?

    - by David Moles
    It looks as though in 2003 or so NCSARequestLog would pick up the system time zone using TimeZone.getDefault().getID(), but in more recent versions it seems as though it's hard-coded to GMT, unless you override it in jetty.xml or programmatically. If true, this kind of annoying, since it means if you don't want GMT logging you have to edit jetty.xml for every installation (not to mention twice a year for daylight saving time). Is there a workaround that will let Jetty pick the time zone up from the system?

  • Architecture for Social Graph data that has a Time Frame Associated?

    - by Jay Stevens
    I am adding some "social" type features to an existing application. There are a limited # of node & edge types. Overall the data itself is relatively small (50,000 - 70,000 for each type of node) there will be a number of edges (relationships) between them (almost all directional). This, I know, is relatively easy to represent with an SDF store (such as BrightstarDB) or something like Microsoft's Trinity (or really many of the noSQL options). The thing that, I think, makes this a unique use case is that each relationship will have a timeframe associated with it (start and end dates). Right now, I'm thinking of just storing this in a relational structure and dealing with the headaches of "traversing the graph", but I'm looking for suggestions on a better approach (both in terms of data structure and server): Column ================ From_Node_ID Relationship To_Node_ID StartDate EndDate Any suggestions or thoughts are welcomed.

  • What programming technique / practice done by you was ahead of its time?

    - by Binoj Antony
    I once built a very good web application in ASP (classic) back in 2001 and extensively used XmlHttpRequest object in it. (I was lucky that the clients were only using IE, and only IE supported this object at that time). Then later when people started talking about AJAX in 2005, It felt good to have used something ahead (or early) of its time. Well, maybe this does not qualify to be listed as something done ahead of its time. Which programming technology/technique/practice have you done that was ahead of this time. One story per answer please. The title for this question taken from an opposite question here.

  • Can you be a web and desktop developer at the same time?

    - by Charmop
    In my environment, I found web programmers, desktop programmers and both web and desktop programmers. About myself I started my career with desktop development using C and then Java, did couple of simple level projects. Then at the final graduating year, my project was a web one, so I turned to web development until this moment. But, when I meet people having chosen to be web or software developers from the beginning, I figure out that they have more knowledge/experience than I have. So I get kind of regret why didn't I specialize my self from the first day? The question is: Is it a good habit to work at two, more or less, different fields: web and desktop? Or we must specialize ourselves?

  • Apache2 + Php + Pthreads HowTos

    - by Drug
    04 LTS 64 bit. What I would really love to do is sudo apt-get install libapache2-mod-php5 but compile PHP with --enable-maintainer-zts so I could later install pthreads with pecl install pthreads. Sadly I understand that it is not possible. I know that the easiest way is to recompile PHP together with apache support and zts. However I really like the way the standard Ubuntu PHP package is configured and I am used to the path`s for CLI php.ini config, Apache php.ini config and other paths for modules and files that this Ubuntu package defines. So i just want to change the package source a little bit and install it. # Get the stuff necessary to build the package sudo apt-get build-dep php5-common # Get the package source sudo apt-get source php5-common At this point I am getting sources not for the php5-common package but the whole php5 package. If I would sudo make && make install at this point, would it mean that I am installing a lot of unnecessary stuff? # Add configuration options ./configure --enable-maintainer-zts Does this mean that I am appending a configuration option? Or am I generating a whole new config? Alternative at this point Is there a way of getting the config options that this package defines, so that I can grab a php source from php.net and compile it with $ ./configure --prefix=package_prefix \ // Option 1 from package --enable-embed \ // Option 2 from package --with-regex=php \ // Option 3 from package Continuing the main idea ... Solution 1 # Compile (Not compiling) sudo make && make install Will I be building PHP with EVERYTHING at this point? If I compile like this, I will not be able to remove the mess I made using sudo apt-get purge php5? Solution 2 # ReCompile the package dpkg-buildpackage -rfakeroot -uc -b This does not compile also. Please correct my steps, so I can install everything correctly.

  • Why does Ubuntu only detect one USB LAN adapters at a time?

    - by EGO
    I try to connect real switch with my computer for an exam preparation, for this purpose I need more than one LAN cards, and there is only one built in LAN card in my computer. So, to get more LAN cards, I bought 4 USB Ethernet adapters (as I have 4 usb ports in may laptop 2 usb 2.0 ports, 2 usb 3.0 ports). When I plug these adapters in my computer Ubuntu only detects one LAN card from 2.0 usb ports, and one LAN card from 3.0 ports. And sometimes detects only one USB LAN from all the usb ports. Actually the real problem is Ubuntu shows these USB LAN adapters in the "lsusb", but does not list them in "ifconfig". Kontron (Industrial Computer Source / ICS Advent) is my LAN USB ethernet. abc@ubuntu:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 8087:0024 Intel Corp.

  • Design pattern to keep track UITableView rows correspondance to underlying data in constant time.

    - by DenNukem
    When my model changes I want to animate changes in UITableView by inserting/deleting rows. For that I need to know the ordinal of the given row (so I can construct NSIndexPath), which I find hard to do in better-than-linear time. For example, consider that I have a list of addressbook entries which are manualy sorted by the user, i.e. there is no ordering "key" that represents the sort order. There is also a corresponding UITableView that shows one row per addressbook entry. When UITableView queries the datasource I query the NSMUtableArray populated with my entries and return required data in constant time for each row. However, if there is a change in underlying model I am getting a notification "Joe Smith, id#123 has been removed". Now I have a dilemma. A naive approach would be to scan the array, determine the index at which Joe Smith is and then ask UITableView to remove that precise row from the view, also removing it form the array. However, the scan will take linear time to finish. Now I could have an NSDictionary which allows me to find Joe Smith in constant time, but that doesn't do me a lot of good because I still need to find his ordinal index within the array in order to instruct UITableView to remove that row, which is again a linear search. I could further decide to store each object's ordinal inside the object itself to make it constant, but it will become outdated after first such update as all subsequent index values will have changed due to removal of an object. So what is the correct design pattern to accurately reflect model changes in the UITableView in costant (or at least logarithmic) time?
