  • Making a python script only be able to run once at a time

    - by Richard
    I am looking to make a python script be unique in the sense that it can only run once at a time. For example if I run the script and open another session of the same script a second time and the first session is still running, then the second session will just exit and do nothing. Anyone knows how I could implement this?

  • Why thread specific data is required in pthread ?

    - by user504542
    Hi As i know, all the threads share memory location. For example a global variable changes in one thread will reflect in another thread. Since each thread has its own stack, the local variables that are created inside the thread is unique. In this case, why do we need to go for thread specific data mechanism?. Can't it be achieved by auto storage varibles inside the thread function ? Kindly clarify!!!. BR Rj

  • Persistent Hashing of Strings in Python

    - by Chris S
    How would you convert an arbitrary string into a unique integer, which would be the same across Python sessions and platforms? For example hash('my string') wouldn't work because a different value is returned for each Python session and platform.

  • jQuery syntax for changing the value of a table cell

    - by cf_PhillipSenn
    I have a table where every row has a unique id. The last table cell has class="status" where I want to show the user the result of their action. In my $.ajax call, I have: ,success: function(result){ $('tr#'+result).td('.status').text('Updated'); }; result is the id of the row that was updated. It's just throwing an error message that says $( and that's all.

  • vhost.conf file in PLESK not working as intended

    - by Saif Bechan
    I have configured a vhost file for my domain but it does not seem to work. These are the steps I took, please correct me if I am wrong. First I made a file called vhost.conf in: /var/www/vhosts/*domain*/conf/vhost.conf The content of the vhost file looks like this: <Directory /var/www/vhosts/*domain*/httpdocs> php_admin_flag engine on php_admin_flag display_errors on </Directory> Now in my /etc/php.ini i set display_errors=Off After everything i rebuild with: /usr/local/psa/admin/sbin/websrvmng -a But I don't see the any errors in my page. When i turn on the display_errors in /etc/php.ini only then can I see the errors. I know for a fact that the vhost file is read, because when i type nonsense values i get an error when restarting apache saying there are errors in the vhost file. Anyone know what the problem can be. Should there be special settings in either the php.ini file or the httpd.conf file. The httpd.conf i edit is in /etc/httpd/conf/httpd.conf. Is this the file that PLESK uses or is there another, because the values i see there do not really reflect the http folders of my domain. The httpd file looks like this now. # The document root DocumentRoot "/var/www/html" # i guess this is the base directory <Directory /> Order Deny,Allow Deny from all Options None AllowOverride None </Directory> # And i guess here are all my domains located, but there aren't any here <Directory "/var/www/html"> Options None AllowOverride None Order allow,deny Allow from all </Directory> Only this directory /var/www/html is not used by me, I use the directory /var/www/vhosts. The only folder found in /var/www/html is a folder called awstats. Does plesk use other files, and where are they located. I hope this all makes sense to anyone, and i hope i can find a solution

  • Understanding Linux SCSI queue depths

    - by Troels Arvin
    I'm experimenting with the effects of different SCSI queue depth values on a Dell server running CentOS Linux 5.4 (x86_64). The server has two QLogic QLE2560 FC HBAs connected via multipathing to a storage system. The storage system has allocated two LUNs to the server, each connected through four paths in an active-active-active-active round-robin configuration. All in all, the two LUNs exist as eight /dev/sdX devices, represented by two devices in /dev/mpath. I currently adjust the queue depth values in /etc/modprobe.conf and check the result (after rebooting) by looking in the seventh column of /proc/scsi/sg/devices. Two questions related to that: Is there a way to adjust queue depths without rebooting or unloading the qla2xxx kernel module? E.g., can I echo a new queue depth value into some /proc or /sys-like file to update the queue depth? If I set the queue depth to 128, is that 128 in total for all devices handled by the qla2xxx module?, or 128 for each HBA? (256 in total), or 128 for each of the eight /dev/sdX devices (1024 in toal)?, or 128 for each of the two /dev/mpath/... devices (256 in total)? This is important for me to know so that my server doesn't flood the storage system, affecting other servers connected to it.

  • How to remove a plain text protecting single quote from all the selected cells in LibreOffice Calc?

    - by Ivan
    I've imported a CSV file having the first column to be date-time values in ISO 8601 format like 2012-01-01T00:00:00.000Z for the first moment of the year 2012. Then, willing to make LibreOffice to recognize the format (as I was looking forward to plot a diagram), I've selected the column, chosen Format Cells... and entered the custom time format as YYYY-MM-DDTHH:MM:SS.000Z And this seems to work if... I edit a cell to remove a hidden single-quote from its beginning (which serves to protect a cell content from being interpreted) as all the newly formatted cells now store values like '2012-01-01T00:00:00.000Z (note the single quote - it is only visible when you edit a particular cell). And I am to do so for all the cells in the column. How can I automate this? UPDATE: I've already found a solution for the particular case of mine: it helps to set a column format to "time" in the CSV import dialogue. But I am still curious how could this be done in case I wouldn't have the original .csv data file to import but only the .ods file with the data already imported without the format specified at the import time.

  • How do I make a Data Validation drop-down exclude blanks?

    - by Iszi
    Related: How can I use non-adjacent cells on another sheet for a Data Validation drop-down, and only show non-blank values? For now, I've worked around the above problem by re-arranging my sheet so all the Data Validation Source cells are in one range. I'm leaving the above question open though, because I think it still poses an interesting problem. However, the issue now is that the Data Validation drop-down isn't working in the way I expected it to (and how I believe others are telling me it should). Even though I've got everything into one named range, Excel still shows blanks in a drop-down that references that range. Setup: Sheet 1 A1= (blank) B1= Header A2= 1 B2= Value1 A3= 2 B3= Value2 A4= 3 B4= Value3 A5= 4 B5= (empty) A6= 5 B6= (empty) A7= 6 B7= (empty) Sheet1!B2:B7 is named Validation Sheet2!A1 is set to use Data Validation with a Source =Validation, and in-cell drop-down. The drop-down in Sheet2!A1 shows: Value1 Value2 Value3 . . . (Dots represent blank lines) How can I get rid of these blank lines in the in-cell drop-down, while still including Sheet1!B5:B7 in the Data Validation Source? Note: I nuked the sheet, and tried it again without column A from Sheet1 (putting values from column B in the above example into column A), and it worked fine. Adding Column A back though, brought the blanks back into the Data Validation drop-down. What do I need to do to keep column A as I want it and keep the in-cell drop-down clean?

  • Limit Apache 2 Memory Usage

    - by UltraNurd
    I am running a hobby webserver off of an ancient Blue & White G3/300 running Debian PPC Squeeze 2.6.30. The performance is okay for a while after a restart, but it eventually gets more and more bogged down. Right now it's at 76 days uptime, and the main culprit seems to be the memory usage of 10+ apache2 processes. I think I need to lower the values for StartServers, MinSpareServers, and/or MaxSpareServers, but I'm not sure which one to adjust, and there are three sections for each depending on which mpm module is in use. How do I tell which of the following sections I need to change, and what are some reasonable values given that the box has 448 MB physical memory (weird upgrade history of one each 64, 128, and 256 sticks)? <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_worker_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_event_module> StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule> There aren't any other instances of StartServers in my apache2.conf, but none of those mpm modules appear in mods-available or mods-enabled. Ideas? Thanks!
