  • Making web server in C with native scripting support

    - by guitar-
    I'm an intermediate C developer, trying to get better. I want to make a very basic and lightweight HTTP server with its own scripting language. Could I use something like Lua for scripting? If not, what? I don't want to use CGI/FastCGI like Apache does for PHP in most cases, I want my server to natively support my scripting language.

  • Where can I find Python tutorials aimed at people who are already programmers?

    - by Chris R
    I'm a reasonably skilled programmer, and I'm interested in branching out into some new languages -- python, specifically -- but frankly I do NOT want to go through a tutorial that assumes I know nothing about programming. I want a tutorial -- again, preferably for python -- that assumes I'm just unfamiliar with the language itself and describes the ways I can use the language to solve problems. Does such a beast exist? I mean, other than the Python wiki?

  • Cannot open database requested by the login. The login failed. Login failed for user

    - by Cipher
    Hi, I have copied a DB from one my computers and using it here. On trying to open the page which requires the fetching content from DB, on con.open I am getting this exception: Unable to open the physical file "E:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\DATA\cakephp.mdf". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Unable to open the physical file "E:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\DATA\cakephp_log.LDF". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Cannot open database "cakephp" requested by the login. The login failed. Login failed for user 'Sarin-PC\Sarin'. I have attached the database from Management Studio Express 2008 and I have also checcked the connection string. Here it is: <connectionStrings> <add name="cn" connectionString="server=.\sqlexpress;database=cakephp;integrated security=true;uid=sarin;pwd=******"/> </connectionStrings> In Visual Studio, when I test the connection, it says "Test connection succeeded". However, there is one strange thing going on. When I login to the Management Studio, there is no + sign with the newly attached database, as shown. If the full WebConfig is reqiured to be seen, I have pasted it here: http://pastebin.com/sVAuN0Ug

  • What do I do about a Java program that spawned two instaces of itself?

    - by user288915
    I have a java JAR file that is triggered by a SQL server job. It's been running successfully for months. The process pulls in a structured flat file to a staging database then pushes that data into an XML file. However yesterday the process was triggered twice at the same time. I can tell from a log file that gets created, it looks like the process ran twice simultaneously. This caused a lot of issues and the XML file that it kicked out was malformed and contained duplicate nodes etc. My question is, is this a known issue with Java JVM's spawning multiple instances of itself? Or should I be looking at sql server as the culprit? I'm looking into 'socket locking' or file locking to prevent multiple instances in the future. This is the first instance of this issue that I've ever heard of. More info: The job is scheduled to run every minute. The job triggers a .bat file that contains the java.exe - jar filename.jar The java program runs, scans a directory for a file and then executes a loop to process if the file if it finds one. After it processes the file it runs another loop that kicks out XML messages. I can provide code samples if that would help. Thank you, Kevin

  • Why is there no middleware in Erlang?

    - by Zubair
    I asked a question earlier about ESBs written in Erlang or Java, and there didn't seem to be anything in Erlang, and only products in Java. http://stackoverflow.com/questions/2453641/what-would-be-the-best-language-in-which-to-write-an-esb/2453683#2453683 I guess I find it difficult to understand why a language like Erlang has no such middleware products, especially seeing as it should be ideally suited to the job.

  • Which Cassandra API provides the highest level of abstraction?

    - by knorv
    There are a lot of Cassandra API:s available and usually the programming language preference determines the choice of API. However, if we take the programming language component out of the equation, what Cassandra API provides the highest level of abstraction? Definition of "level of abstraction" in this context: An API providing a lot of extra goodies such as index handling, etc would be considered being at a higher abstraction layer than a bare bones "close to Thrift" API.

  • AS3: How can I access a movieclip in a different scene?

    - by kentos
    I want to access a MovieClip in another scene than I'm currently in. More specific I want to set a TextField to a certain value from a "preloader"-scene. This is for handling totally dynamic language phrases. Maybe this is the wrong way. I'm loading a XML with language phrases that I want to replace the textfields with. We could do this by altering all MovieClips, but I think this could be a smart solution, if it's possible! :)

  • Debugging Widget causes ANR

    - by Salv0
    I'm trying to debug an AppWidget but I incurred in a problem :D I placed a breakpoint on the top of the method: public void onReceive(Context context, Intent intent) { Log.v(TAG, "onReceive 1"); // BP on this line super.onReceive(context, intent); String action = intent.getAction(); // Checks on action and computations ... Log.v(TAG, "onReceive 2"); updateWidget(context); Log.v(TAG, "onReceive 3"); } The breakpoint stops the execution as expected but then the process dies. The problem is that the breakpoint ( I guess xD ) cause an ANR and the ActivityManager kills the process. That's the Log: 01-07 14:32:38.886: ERROR/ActivityManager(72): ANR in com.salvo.wifiwidget 01-07 14:32:38.886: INFO/Process(72): Sending signal. PID: 475 SIG: 9 ...... ...... 01-07 14:32:38.906: INFO/ActivityManager(72): Process com.salvo.wifiwidget (pid 475) has died. This cause the debug to stop. So the question is: there's a way to debug the widget without incurring in the ANR?? thanks in advance for the answers

  • Book with C programs that have real programming examples.

    - by Siamore
    This is my first question on Stack Overflow, I would like to know about any c programming books that have real programs to introduce real problems as opposed to standard books with examples aimed to teach the language it should be sort of like a challenge with solutions so that concepts like recursion can be used i know that i should find solutions to existing problems to learn the language but this is my first attempt and i find it hard to understand some simple problems so i was hoping for a book with solutions.

  • Rails app Hangs and Ruby uses 100% CPU

    - by tuzzolotron
    I have an apache2 server running Phusion Passenger. On this machine I have two virtual hosts setup each look like this (path's are different for the 2nd virtualhost...but other directives are the same) ServerName beta.mysite.us DocumentRoot "/var/www/beta/mysite/public" <Directory "/var/www/beta/mysite/public"> RewriteEngine on AllowOverride All Options FollowSymLinks </Directory> # http://www.modrails.com/documentation/Users guide.html PassengerAppRoot "/var/www/beta/mysite" RailsEnv development PassengerMaxPoolSize 6 PassengerDefaultUser mysite # PassengerHighPerformance does come at a trade off of lack of support for mod_rewrite PassengerHighPerformance off RailsSpawnMethod conservative RailsFrameworkSpawnerIdleTime 0 RailsAppSpawnerIdleTime 0 PassengerPoolIdleTime 300 ErrorLog "/var/log/httpd/mysite-beta-error_log" CustomLog "/var/log/httpd/mysite-beta-access_log" common Apache starts fine. I can go to one of the virtualhosts and it will load Rails and work. When I go to the second virtualhost, a ruby process spawns ("Rails: /var/www/mysite/current" according to ps awuxf) and uses 100% CPU. This process never exits. At this point neither virtualhost is responsive. If I kill the the offending ruby process, another ruby process replaces it and uses 100% cpu. If I kill these processes about 5-6 times, then both virtualhosts respond but they, are somehow, running the same Rails app?! I have another virtualhost on this machine that is not setup with phusion passenger..This one never exhibits any problems. Any help / ideas would be much appreciated!

  • Would Python make a good substitute for the Windows command-line/batch scripts?

    - by Lawrence Johnston
    I've got some experience with Bash, which I don't mind, but now that I'm doing a lot of Windows development I'm needing to do basic stuff/write basic scripts using the Windows command-line language. For some reason said language really irritates me, so I was considering learning Python and using that instead. Is Python suitable for such things? Moving files around, creating scripts to do things like unzipping a backup and restoring a SQL database, etc.

  • Why is Python so slow?

    - by Riemannliness
    Why is Python such a slow language, on average, compared to C/C++? I learned Python as my first programming language, but I've only just started with C and already I can feel and see the difference.
