  • How can I add file locations to a database after they are uploaded using a Perl CGI script?

    - by Paul K
    I have a CGI program I have written using Perl. One of its functions is to upload pics to the server. All of it is working well, including adding all kinds of info to a MySQL db. My question is: How can I get the uploaded pic files location and names added to the db? I would rather that instead of changing the script to actually upload the pics to the db. I have heard horror stories of uploading binary files to databases. Since I am new to all of this, I am at a loss. Have tried doing some research and web searches for 3 weeks now with no luck. Any suggestions or answers would be greatly appreciated. I would really hate to have to manually add all the locations/names to the db. I am using: a Perl CGI script, MySQL db, Linux server and the files are being uploaded to the server. I AM NOT looking to add the actual files to the db. Just their location(s).

  • Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in file

    - by Jian Lin
    Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in files (pushing it)? It can be important that: 1) You never know it is in an inconsistent state, so you try for 2 hours trying to debug the code for what's wrong. 2) With all the framework code -- potentially hundreds of files -- if some files are inconsistent with the other, can't the rake db:migrate or script/generate controller cause some damage or inconsistencies to the code base?

  • SWI-Prolog: how to load rdf triples using semweb/rdf_db library?

    - by Li Li
    Hi, I have a rdf file (file.trp) in n-triples format, where each line is: "subject predicate object ." I tried to use rdf_load in semweb/rdf_db to load it into memory, but failed. Here is what I tried: ?- rdf_load('file.trp'). ?- rdf_load('file.trp', [format(triples]). the manual says it supports xml and triples. But it only loads rdf xml files. How can I load such rdf triple file? Thanks, Li

  • How can I save a file on an http server using just http requests and javascript?

    - by user170902
    hi all, I'm trying to understand some of the basics of web servers/html/javasacript etc. I'm not interested in any of the various frameworks like php/asp, i'm just trying to get a low level look at things (for now). At the moment I'm trying to understand how data can be sent to/saved on the backend, but i must admit that i'm getting a bit lost under the various specs/technical stuff on w3 at the moment! If I have some data, say xml, that I want to save on the backend how do I go about it? I assume that I would have to use something like an HTTP PUT or POST Request to an html doc that contains some javascript that in turn would process the data, e.g. save it somewhere. Now from googling around I can see that this doesn't seem to be the case, so my assumptions are completely wrong! So how is it done? Can it be done, or do I have to use something like php or asp? TIA. bg

  • How come the [L] flag isn't working in my .htaccess file?

    - by George Edison
    Here are the rules: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ index.php?action=home [L] RewriteRule ^[\w\W]*$ error.php [L] When a page matches the first one, it is supposed to ignore any other further rules. Yet accessing / results in error.php being invoked. Commenting out the second rule works as intended - the page redirects to index.php. What am I doing wrong? Also: is there a better way to write the last line? It's basically a catch-all.

    I have my application online on the Google Apps Engine. When I deploy this application, this error is generated. I am using Netbeans 6.9. My jdk is installed at : "C:\Program Files\Java\jdk1.6.0_23\". I have installed Google App Engine for Java. This application is getting deployed & run on localhost very well. I am also able to start Google App Engine Server. I have set Environment variables as : 1) classpath : C:\Program Files\Java\jdk1.6.0_23\bin; 2) path : C:\Program Files\Java\jdk1.6.0_23\bin; 3) JAVA_HOME : C:\Program Files\Java\jdk1.6.0_23\bin; 4) include : C:\Program Files\Java\jdk1.6.0_23\include; 5) lib : C:\Program Files\Java\jdk1.6.0_23\lib; However, in system32, I am not finding java.exe, javac.exe or javawc.exe.

  • How to edit files on the users file system from my web server?

    - by Abs
    Hello all, I am really looking for implementation advice as I have entered a new realm that I am not familiar with. At the simplest level, I would like to find a way that I can read/write to a users machine from my web server. For this to work, I think I will have to install some sort of "plugin" on the users machine which can receive (or poll?) the server for instructions. The above is the line of thought that I currently have, maybe using JAVA to do this. This needs to work on Linux, Mac and Windows OS. I am really looking for advice on the above, is it a good idea? Is there a better way of doing this? Is there something out there already that I can build on top of? I really appreciate all input and advice as this is something I have not done before. Thanks all

    In development mode I would like to have assets served locally and when deployed in production I would like them served from the CDN. Anyone using play2 and serving content from CDN be willing to share how they are doing it? // Thinking of something like this in the routes file... @if(play.Play.isDev()) { GET /assets/*file controllers.Assets.at(path="/public", file) } else { GET CDNPATH/assets/*file controllers.Assets.at(path="CDNPATH", file) } (Note: using 2.0.2 because of the headers fix https://github.com/playframework/Play20/pull/276)
