  • Redirect subdomain to hidden folder using mod_rewrite

    - by radious
    Hello! I want to keep my blog in subfolder domain_com/htdocs/blog and access it using blog.domain.com. I can obtain it using apache's mod_rewrite: RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} ^blog\.domain\.com RewriteCond %{HTTP_HOST} !^/blog RewriteRule ^(.*)$ /blog/$1 [L] But I also want to redirect hxxp://domain.com/blog to hxxp://blog.domain.com (simply because I want to hide it from users). Simple redirection like: RewriteCond %{HTTP_HOST} ^wojtyniak\.com$ RewriteRule %{REQUEST_URI} ^/foo RewriteRule ^(.*)$ http://foo.wojtyniak.com [L,R=301] causes redirection loop. Is there any way to make such a redirection without loop? Big thanks! PS. Sorry for those hxxp thing, but serverfault thinks these are link and doesn't allow me to post more than one.

  • Backup and Restore ADAM database

    - by kuoson
    Hi, I was trying to backup and restore an ADAM database to a different server the other day. I copied all files under "Program Files/Microsoft ADAM" folder to the same path in the destination server and started the ADAM service in the destination server up. Although the service come back up successfully and I was able to connect to the instance with ADAM ADSI Edit mmc snap-in, I found I had to reset every single user's password before they can login again. Has anyone got this issue before? Is the password encrypted with the server IP address or something like that?

  • FFMPEG Segfault Solutions

    - by Brentley_11
    I'm trying to convert a bunch of movies into h.264 mp4's using FFMPEG. These movies are sourced from various portable camcorders such as the Flip Mino HD and the Kodak ZI8. One issue I'm having with video from the ZI8 is it seems to be causing FFMPEG to segfault. Here is my command: ffmpeg -i 'XmasSailor720p60fps.MOV' -threads 2 -acodec libfaac -ab 96kb -vcodec libx264 -vpre hq -b 500kb -s 484x272 XmasSailor.mp4 Here is the output: FFmpeg version SVN-r20668, Copyright (c) 2000-2009 Fabrice Bellard, et al. built on Dec 2 2009 18:37:34 with gcc 4.2.4 (Ubuntu 4.2.4-1ubuntu4) configuration: --enable-libfaac --enable-libfaad --enable-libmp3lame --enable-libx264 --enable-gpl --enable-nonfree --enable-postproc --enable-pthreads --enable-shared libavutil 50. 5. 1 / 50. 5. 1 libavcodec 52.42. 0 / 52.42. 0 libavformat 52.39. 2 / 52.39. 2 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0. 7. 2 / 0. 7. 2 libpostproc 51. 2. 0 / 51. 2. 0 Seems stream 0 codec frame rate differs from container frame rate: 59.94 (60000/1001) -> 29.97 (30000/1001) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'XmasSailor720p60fps.MOV': Duration: 00:00:05.37, start: 0.000000, bitrate: 12021 kb/s Stream #0.0(eng): Video: h264, yuv420p, 1280x720 [PAR 1:1 DAR 16:9], 11994 kb/s, 29.97 tbr, 90k tbn, 59.94 tbc Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16, 128 kb/s Metadata major_brand : qt minor_version : 0 compatible_brands: qt comment : KODAK Zi8 Pocket Video Camera comment-eng : KODAK Zi8 Pocket Video Camera [libx264 @ 0x99e1020]using SAR=1/1 [libx264 @ 0x99e1020]using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.1 Cache64 [libx264 @ 0x99e1020]profile High, level 2.1 Output #0, mp4, to 'XmasSailor.mp4': Stream #0.0(eng): Video: libx264, yuv420p, 484x272 [PAR 1:1 DAR 121:68], q=10-51, 500 kb/s, 30k tbn, 29.97 tbc Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16, 96 kb/s Metadata comment : Encoded with the Statusfirm Video Transcoder Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding [h264 @ 0x99de950]B picture before any references, skipping [h264 @ 0x99de950]decode_slice_header error [h264 @ 0x99de950]no frame!

  • Boot Vista x64 with both ICH8 and ICH10 AHCI support

    - by adurity
    I have a situation where I need to boot Windows Vista 64-bit from both a ICH10 and ICH8 AHCI SATA controller. Currently, it is setup to boot from the ICH10, but when I try booting with the ICH8, I get the famed Windows STOP 7B BSOD. How can I add the ICH8 driver so that I can work around this BSOD and boot the system? I have updated to the latest Intel AHCI driver (8.9.0.1023 as of this post) which is supposed to support both chipsets, but I feel I am missing something.

  • Enabling super single user mode with SQL Server

    - by simonsabin
    I recently got an email from a fellow MVP about single user mode. It made me think about some features I had just been looking at and so I started playing. The annoyance about single user mode for SQL Server is that its not really single user, but more like single connection mode. So how can you get round it, well there is extension to the -m startup option that allows you to specify an application name, and only connections with that application name can connect. This is very useful if you have...(read more)

  • How to access pixels of an NSBitmapImageRep?

    - by Paperflyer
    I have an NSBitmapImageRep that is created like this: NSBitmapImageRep *imageRep = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:waveformSize.width pixelsHigh:waveformSize.height bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:YES colorSpaceName:NSCalibratedRGBColorSpace bytesPerRow:0 bitsPerPixel:0]; Now I want to access the pixel data so I get a pointer to the pixel planes using unsigned char *bitmapData; [imageRep getBitmapDataPlanes:&bitmapData]; According to the Documentation this returns a C array of five character pointers. But how can it do that? since the type of the argument is unsigned char **, it can only return an array of chars, but not an array of char pointers. So, this leaves me wondering how to access the individual pixels. Do you have an idea how to do that? (I know there is the method – setColor:atX:y:, but it seems to be pretty slow if invoked for every single pixel of a big bitmap.)

  • git - how do we verify commit messages for a push?

    - by shovas
    Coming from CVS, we have a policy that commit messages should be tagged with a bug number (simple suffix "... [9999]"). A CVS script checks this during commits and rejects the commit if the message does not conform. The git hook commit-msg does this on the developer side but we find it helpful to have automated systems check and remind us of this. During a git push, commit-msg isn't run. Is there another hook during push that could check commit messages? How do we verify commit messages during a git push?

  • Accumulate 2D Array by Index

    - by Tegan Snyder
    I have an array that looks like this: Array ( [0] => Array ( [amount] => 60.00 [store_id] => 1 ) [1] => Array ( [amount] => 40.00 [store_id] => 1 ) [2] => Array ( [amount] => 10.00 [store_id] => 2 ) ) What would be a good method to reduce the array to a similar array that totals the 'amount' related to a store_id. For Instance I'd like to get this: Array ( [0] => Array ( [amount] => 100.00 [store_id] => 1 ) [2] => Array ( [amount] => 10.00 [store_id] => 2 ) )

  • Multlingual redirect

    - by israkir
    I want to ignore the post form in the django's internatonalization. I am using the django-multilingual app, so I have different fields for different languages in the db. I come up with this idea: For each language, from the index.html page, redirect to a different url (e.g. /en/ or /de/ or /zh/). And each view of this urls, set the session according to the language like this: def set_lang_en(request): request.session['django_language'] = 'en' render_to_response("home.html") def set_lang_zh(request): request.session['django_language'] = 'zh-cn' render_to_response("home.html") Interestingly, this does the job, but if i refresh the page again after redirection (home.html). Why it is like this? And how can solve this problem either in my direction or other one?

  • Implement the Combine function using templates

    - by gkid123
    any idea on how to do it for template? thanks Implement the Combine function using templates. The Combine fn applies a function of two arguments cumulatively to the items of an STL container, from begin() to end(), so as to reduce the sequence to a single value. For example, Combine(<list containing 6,3,1,9,7>, std::plus<int>()) should calculate ((((6+3)+1)+9)+7). class NotEnoughElements {}; template <typename Container, typename Function> typename Container::value_type Combine(const Container& c, Function fn) throw (NotEnoughElements) { your code goes here }

  • Want to load jquery dialog from a different web-page

    - by Jake
    I'm a bit of a n00b with jquery so this one is probably an RTFM question: I'm writing an application to create a somewhat complex record for my client. Building the record requires doing a couple of server side searches inside a dialog. Right now I have everything framed up in 1 file (asp.net) and it's ok. But I can see as I add the business logic and the communication with the server this is going to get really ugly. I'm alreay putting most of the javascript in external files, but I'd like to move the HTML for the dialogs out too. How do I get the jquery dialog method to load the dialog body from the html files? Something like: getDialogHTML(dialogHolderDiv); <---magic goes here var dialogOptions = { ... }; $("#"+dialogHolderDiv).dialog(dialogOptions); $("#"+dialogHolderDiv).dialog('open'); any help will be apperciated .

  • What file format can represent an uncompressed raster image at 48 or 64 bits per pixel?

    - by finnw
    I am creating screenshots under Windows and using the LockBits function from GDI+ to extract the pixel data, which will then be written to a file. To maximise performance I am also: Using the same PixelFormat as the source bitmap, to avoid format conversion Using the ImageLockModeUserInputBuf flag to extract the pixel data into a pre-allocated buffer This pre-allocated buffer (pointed to by BitmapData::Scan0) is part of a memory-mapped file (to avoid copying the pixel data again.) I will also be writing the code that reads the file, so I can use (or invent) any format I wish. However I would prefer to use a well-known format that existing programs (ideally web browsers) are able to read, because that means I can visually confirm that the images are correct before writing the code for the other program (that reads the image.) I have implemented this successfully for the PixelFormat32bppRGB format, which matches the format of a 32bpp BMP file, so if I extract the pixel data directly into the memory-mapped BMP file and prefix it with a BMP header I get a valid BMP image file that can be opened in Paint and most browsers. Unfortunately one of the machines I am testing on returns pixels in PixelFormat64bppPARGB format (presumably this is influenced by the video adapter driver) and there is no corresponding BMP pixel format for this. Converting to a 16, 24 or 32bpp BMP format slows the program down considerably (as well as being lossy) so I am looking for a file format that can use this pixel format without conversion, so I can extract directly into the memory-mapped file as I have done with the 32bpp format. What raster image file formats support 48bpp and/or 64bpp?

  • Proper way in Python to raise errors while setting variables

    - by ensnare
    What is the proper way to do error-checking in a class? Raising exceptions? Setting an instance variable dictionary "errors" that contains all the errors and returning it? Is it bad to print errors from a class? Do I have to return False if I'm raising an exception? Just want to make sure that I'm doing things right. Below is some sample code: @property def password(self): return self._password @password.setter def password(self,password): # Check that password has been completed try: # Check that password has a length of 6 characters if (len(password) < 6): raise NameError('Your password must be greater \ than 6 characters') except NameError: print 'Please choose a password' return False except TypeError: print 'Please choose a password' return False #Set the password self._password = password #Encrypt the password password_md5 = md5.new() password_md5.update(password) self._password_md5 = password_md5.hexdigest()

  • Template access of symbol in unnamed namespace

    - by Fred Larson
    We are upgrading our XL C/C++ compiler from V8.0 to V10.1 and found some code that is now giving us an error, even though it compiled under V8.0. Here's a minimal example: test.h: #include <iostream> #include <string> template <class T> void f() { std::cout << TEST << std::endl; } test.cpp: #include <string> #include "test.h" namespace { std::string TEST = "test"; } int main() { f<int>(); return 0; } Under V10.1, we get the following error: "test.h", line 7.16: 1540-0274 (S) The name lookup for "TEST" did not find a declaration. "test.cpp", line 6.15: 1540-1303 (I) "std::string TEST" is not visible. "test.h", line 5.6: 1540-0700 (I) The previous message was produced while processing "f<int>()". "test.cpp", line 11.3: 1540-0700 (I) The previous message was produced while processing "main()". We found a similar difference between g++ 3.3.2 and 4.3.2. I also found in g++, if I move the #include "test.h" to be after the unnamed namespace declaration, the compile error goes away. So here's my question: what does the Standard say about this? When a template is instantiated, is that instance considered to be declared at the point where the template itself was declared, or is the standard not that clear on this point? I did some looking though the n2461.pdf draft, but didn't really come up with anything definitive.

  • Building Web Application project using MSBuild from command line on 64-bit: missing targets file

    - by James Allen
    Building a solution containing a web application project using MSBuild from powershell like this: msbuild "/p:OutDir=$build_dir\" $solution_file Works fine for me on 32-bit, but on a 64-bit machine I am running into this error: error MSB4019: The imported project "C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk. I am using Visual Studio 2008 and powershell v2. The problem has already been documented here and here. Basically on 64-bit install of VS, the Microsoft.WebApplication.targets needed by MSBuild is in the Program Files(x86) dir, not the Program Files dir, but MSBuild doesn't recognise this and so looks in the wrong place. The two solutions are not ideal: Manually copy the file on 64-bit from Program Files(x86) to Program Files. This is a poor solution - every dev will have to do this manually. Manually edit the csproj file so MSBuild looks in the right place. Again not ideal: I would rather not have to get everyone on 64bit to manually edit csproj files on every new project. e.g. <Import Project="$(MSBuildExtensionsPathx86)\$(WebAppTargetsSuffix)" Condition="Exists('$(MSBuildExtensionsPathx86)\$(WebAppTargetsSuffix)')" /> Ideally I want a way to tell MSBuild to import the target file form the right place from the command line but I can't work out how to do that. Any solutions?
