  • How would I change the DocumenRoot on the version of Apache that came pre-installed on my Mac OS X s

    - by racl101
    OK, so I want to take advantage of the Apache server that comes installed on my Mac OS X system (which means, I would like not to have to install my own version of Apache since I might as well tryto use what comes bundled), and as such, I went to change some settings in the configuration file: /etc/apache2/httpd.conf Namely, I changed the these two lines: DocumentRoot "/Users/myusername/Sites" <Directory "/Users/myusername/Sites"> So that they initially pointed to a folder in my Dropbox folder (so I could have my docs sync to my Dropbox): DocumentRoot "/Users/myusername/Dropbox/public_html" <Directory "/Users/myusername/Dropbox/public_html"> That didn't work. So then I figured, ok maybe it was too much to ask to make folder in my Dropbox be my document root. So then I thought, what if I make the Document root another folder of my choosing like so: DocumentRoot "/Users/myusername/dev-sites/public_html" <Directory "/Users/myusername/dev-sites/public_html"> and that didn't work either. After looking within the httpd.conf file for clues it seems that only two directories appear to work as Document root paths for the Apache that comes bundled with Mac OS X: /Users/myusername/Sites (or ~/Sites) and /Library/WebServer/Documents/ But trying to use any other directories didn't seem to work. I would get 403 errors on my browser. I was wondering if there was some other settings to change on the httpd.conf file or any permissions to set to make this work. Any help would be appreciated and many thanks in advance.

  • Eclipse ant build gives "Another singleton version selected", how can I stop that?

    - by Fredrik
    We run org.eclipse.ant.core.antRunner to build our plugins and RCP projects. In the build logs we get a ton of messages like: [eclipse.buildScript] Bundle org.eclipse.X: [eclipse.buildScript] Another singleton version selected: org.eclipse.equinox.X_1.0.4.v20081112-1019 The reason is clear; There are two different versions of a particular bundle and it chose the latest. We cannot change the Eclipse installation to remove the older plugins, so what can be done to get rid of these messages? Bonusquestion: What class prints out these messages? One option could be to create our own version where these messages are never shown.

  • Sortie de Qt 5 beta, cette préversion montre l'achèvement de la modularisation du framework

    Sortie de Qt 5 alpha La première version majeure du Qt Project autonome se concentre sur les performances et les capacités graphiques La version 5 de Qt vient de sortir en version alpha. Cette version est la première version majeure depuis que Qt est devenu autonome avec la création du Qt Project. Beaucoup de personnes ont contribué à cette nouvelle version, pas uniquement des développeurs de chez Nokia. Les différents modules ont été regroupés en deux catégories, les essentiels, installés par défaut, et les add-ons, installés à la demande. L'objectif de cette version alpha est de récupérer les retours des utilisateurs, principalement sur les modules essentiels. Lars Knoll, le responsable...

  • Multi-threaded random_r is slower than single threaded version.

    - by Nixuz
    The following program is essentially the same the one described here. When I run and compile the program using two threads (NTHREADS == 2), I get the following run times: real 0m14.120s user 0m25.570s sys 0m0.050s When it is run with just one thread (NTHREADS == 1), I get run times significantly better even though it is only using one core. real 0m4.705s user 0m4.660s sys 0m0.010s My system is dual core, and I know random_r is thread safe and I am pretty sure it is non-blocking. When the same program is run without random_r and a calculation of cosines and sines is used as a replacement, the dual-threaded version runs in about 1/2 the time as expected. #include <pthread.h> #include <stdlib.h> #include <stdio.h> #define NTHREADS 2 #define PRNG_BUFSZ 8 #define ITERATIONS 1000000000 void* thread_run(void* arg) { int r1, i, totalIterations = ITERATIONS / NTHREADS; for (i = 0; i < totalIterations; i++){ random_r((struct random_data*)arg, &r1); } printf("%i\n", r1); } int main(int argc, char** argv) { struct random_data* rand_states = (struct random_data*)calloc(NTHREADS, sizeof(struct random_data)); char* rand_statebufs = (char*)calloc(NTHREADS, PRNG_BUFSZ); pthread_t* thread_ids; int t = 0; thread_ids = (pthread_t*)calloc(NTHREADS, sizeof(pthread_t)); /* create threads */ for (t = 0; t < NTHREADS; t++) { initstate_r(random(), &rand_statebufs[t], PRNG_BUFSZ, &rand_states[t]); pthread_create(&thread_ids[t], NULL, &thread_run, &rand_states[t]); } for (t = 0; t < NTHREADS; t++) { pthread_join(thread_ids[t], NULL); } free(thread_ids); free(rand_states); free(rand_statebufs); } I am confused why when generating random numbers the two threaded version performs much worse than the single threaded version, considering random_r is meant to be used in multi-threaded applications.

  • Why wouldn't an embedded silverlight control work in a page?

    - by rsteckly
    Hi, I have a silverlight application project in my solution. The other project is a web application project that has a .xap file in ClientBin. When I created the silverlight project, it asked if I wanted the asp.net application to host it (and I said yes). In the root directory, there is a test page for the silverlight control. That loads the control. In another directory, I insert the SAME asp markup to get the silverlight control to launch again. Nothing happens. Why would the silverlight launch on one page and not on the other? Can people help point me to documentation about dependencies that I might not know about? I've put a reference to Silverlight.js on the page as well. Here's the markup: <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="../ClientBin/Editor.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40818.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40818.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </div>

  • How do I get Tomcat 7 to start up faster in Linux CentOS kernel version 2.6.18?

    - by user1786833
    I am experiencing a problem with slow start up times for Tomcat 7. I have done some testing by tweaking configuration parameters both on Linux CentOS kernel version 2.6.18 and on Windows 7 using this link as my primary guide: http://wiki.apache.org/tomcat/HowTo/FasterStartUp and managed only a modest improvement. The improvements seemed to result when I added metadata-complete="true" attribute to the element of my WEB-INF/web.xml file and when I added the names of almost all the jars we use for our application to the tomcat.util.scan.DefaultJarScanner.jarsToSkip property in conf/catalina.properties file. I've also used this JAVA_OPTS in the setenv.sh file: JAVA_OPTS="$JAVA_OPTS -server -Xms1536m -Xmx1536m -XX:MaxPermSize=256m -XX:NewRatio=2 -XX:+UseParallelGC -XX:ParallelGCThreads=2 -Dsun.rmi.dgc.client.gcInterval=1800000 -Dsun.rmi.dgc.server.gcInterval=1800000 -Dorg.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true " but actually saw my start up times increase slightly. Our QA and production environments are on Linux CentOS so I'm hoping to get more information on improving Tomcat 7 start up times in that environment. My primary role is java developer and I don't have much system administration experience so I appreciate any input. Thank you for your time and suggestions.

  • My Windows 7 is getting the "An error occurred. Press control+alt+del" message on boot

    - by Maxrunner
    So I upgraded my ubuntu to 12.10 but the Windows 7 problem seems to have happened not after doing the upgrade but later. I am not sure. Ubuntu is running fine, but how can I recover my Windows7? I tried running BootRepair in Ubuntu but it keeps scanning system endlessly... If I recover Windows with the Windows DVD I assume I will lose the GRUB menu and then not possible to start Ubuntu. How do i then proceed to recover the GRUB? Can I recover using the Ubuntu DVD?

  • What is the most efficient functional version of the following imperative code?

    - by justin.r.s.
    I'm learning Scala and I want to know the best way of expressing this imperative pattern using Scala's functional programming capabilities. def f(l: List[Int]): Boolean = { for (e <- l) { if (test(e)) return true } } return false } The best I can come up with is along the lines of: l map { e => test(e) } contains true But this is less efficient since it calls test() on each element, whereas the imperative version stops on the first element that satisfies test(). Is there a more idiomatic functional programming technique I can use to the same effect? The imperative version seems awkward in Scala.

  • Where can I legally obtain the 64bit version of Windows 8?

    - by Harsha K
    No, I am not looking to pirate. I bought a key through the Upgrade assistant (for just $15 due to the upgrade offer), but it downloaded an iso file that was between 2.3 and 2.5 GB. Which doesn't make sense to me, because the Evaluation version of Windows 8 x64 is closer to 3.4 GB in size. I assumed the Upgrade Assistant would be intelligent enough to realize that it is being run on a Windows 7 x64 machine and by extension, download the x64 code. Previously, I was able to legally download the ISOs (sans the keys, of course) from the Digital River host. I do not see an option to do that. I'm not interested in risking downloading a tampered ISO. I want to do it through Microsoft channels, but I just don't see how. As you may imagine, search terms such as "Windows 8 official download link" result in a plethora of obviously spyware infested piracy sites. If there's any non-exposing way for me to prove that I have legally purchased Windows and I'm genuinely looking for this answer, please let me know. For reference to what I am looking for it is similar to the answer given in this question for Windows 7: Where do I download Windows 7 (legally from Microsoft)?

  • Excel on Mac Mini OS X Version 10.7.2 - Create text file named after a cell containing other cell data from other cells

    - by user143041
    I tried using the code below for the Excel program on my `Mac Mini using the OS X Version 10.7.2 and it keeps saying Error due to file name / path: (The Excel fiel I am creating is going to be a template with my formulas and macros installed which will be used over and over). Sub CreateFile() Do While Not IsEmpty(ActiveCell.Offset(0, 1)) MyFile = ActiveCell.Value & ".txt" fnum = FreeFile() Open MyFile For Output As fnum Print #fnum, ActiveCell.Offset(0, 1) & " " & ActiveCell.Offset(0, 2) Close #fnum ActiveCell.Offset(1, 0).Select Loop End Sub What Im trying to do: 1st Objective I would like to have the following data to be used to create a text file. A:A is what I need the name of the file to be. B:2 is the content I need in the text file. So, A2 - "repair-video-game-Glassboro-NJ-08028.txt" is the file name and B2 to be the content in the file. Next, A3 is the file name and B3 is the content for the file, etc. ONCE the content reads what is in cell A16 and B16 (length will vary), the file creation should stop, if not then I can delete the additional files created. This sheet will never change. Is there a way to establish the excel macro to always go to this sheet instead of have to select it with the mouse to identify the starting point? 2nd Objective I would like to have the following data to be used to create a text file. A:1 is what I need the name of the file to be. B:B is the content I want in the file. So, A2 - is the file name "geo-sitemap.xml" and B:B to be the content in the file (ignore the .xml file extension in the photo). ONCE the content cell reads what is in cell "B16" (length will vary), the file creation should stop, if not then I can adjust the cells that have need content (formulated content you see in the image is preset for 500 rows). This sheet will never change. Is there a way to establish the excel macro to always go to this sheet instead of have to select it with the mouse to identify the starting point? I can Provide the content in the cells that are filled in by excel formulas that are not not to be included in the .txt files. It is ok if it is not possible. I can delete the extra cells that are not populated (based on the data sheet). Please let me know if you need any more additional information or clarity and I will be happy to provide it. I really appreciate your help! Thank you

  • Which free VNC server works well with Windows 7 and how to advertise it via Bonjour for control by a

    - by GJ
    Hi I need to control a Windows 7 PC via VNC from a Mac in an office LAN. Since the IPs are dynamically assigned, I'd like the PC to appear in my "Places" and in the automatically detected nearby servers in VNC client I'm using -- both of which require the PC to advertise its VNC server via Bonjour (right?). I tried installing ultravnc, which works when I access it directly by IP, but it doesn't seem to advertise itself in the network. Any ideas?
