  • Python list should be empty on class instance initialisation, but it's not. Why?

    - by canavanin
    Hi everyone! I would like to create instances of a class containing a list that's empty by default; instead of later setting this list to the final full list I would like to successively add items to it. Here's a piece of sample code illustrating this: #!/usr/bin/python class test: def __init__(self, lst=[], intg=0): self.lista = lst self.integer = intg name_dict = {} counter = 0 for name in ('Anne', 'Leo', 'Suzy'): counter += 1 name_dict[name] = test() name_dict[name].integer += 1 name_dict[name].lista.append(counter) print name, name_dict[name].integer, name_dict[name].lista When I ran the above program I expected to get Anne 1 [1] Leo 1 [2] Suzy 1 [3] as I assumed lista to always be initialised to an empty list. What I got instead was this: Anne 1 [1] Leo 1 [1, 2] Suzy 1 [1, 2, 3] If I replace self.lista = lst by self.lista = [] it works fine, just like when I add the line name_dict[name].lista = [] to the for loop. Why is it that the contents of the previous objects' lists are retained, yet their values of integer aren't? I am rather new to Python, so it would be great if someone could point out to me where my thoughts/assumptions have gone astray. Thanks a lot in advance for your replies.

  • PHP-FPM bind issues

    - by Leo
    I have a setup of a mac server running Nginx 1.2.3, PHP-FPM 5.3.10 on OSX Lion. It works fine with Nginx on port 8080 ( using port fordwaring on from 80 ) and PHP-FPM listening on 9000. Both are running as /System/LaunchDaemons. My issue is that the system log is full of these errors ( every ten seconds ) which despite the fact the system works I don't like. Sep 10 19:59:05 mac-server php-fpm[974]: [10-Sep-2012 19:59:05] ERROR: unable to bind listening socket for address '127.0.0.1:9000': Address already in use (48) Sep 10 19:59:05 mac-server php-fpm[974]: [10-Sep-2012 19:59:05] ERROR: FPM initialization failed Sep 10 19:59:05 mac-server com.apple.launchd[1] (php-fpm): Throttling respawn: Will start in 10 seconds I have pretty much an out of the box php-fpm config. Could someone please point me to what configuration variables may be causing this problem. There are not any errorneous LaunchAgent/LaunchDaemons floating around either?

  • PHP-APC Installation

    - by Leo
    Trying to get my head around the way to install APC cache on PHP 5.3.13. That's a VPS with apache, configured preferably through whm/cpanel (although not only). I read a bunch of articles where it was suggested to use FastCGI with APC, as suPHP doens't do well with opcode caching, and fcgid_module doesn't do it right for APC either. Noted that fcgid_module is a newer package than FastCGI and that's what whm/cpanel installs for you but ok, that can be solved I guess. Then I'm reading that php-fpm is a much better alternative to manage the php processes, especially for APC. Ok. Then I realised that php-fpm is included in php core since 5.3 and got confused. Does that mean I don't have to use FastCGI/fcgid_module (and what should I use instead of them - mod_php or cgi?)? Or does that mean that I still need to get the older FastCGI module, and configure it to use one process per user (or just one process?)? Or would fcgid_module work as well? And how bad would it be just to go with mod_php/APC to avoid troubles of installing php-fpm and FastCGI (whm/cpanel doesn't support neither) given than Varnish would serve most of the static content anyway - no php process need to be created for static content. Any examples of their FastCGI/fcgid_module/php-fpm/APC configurations would be greatly appreciated as well.

  • OSX: Selecting default application for all unknown and different file types (extensions)

    - by Leo
    I work in cluster computing and am using Mac OS X 10.6. I send off hundreds of computing jobs a day, and each one comes back with with a different extension. For example, svmGeneSelect.o12345 which is the std output of my svmGeneSelect job which is job number 12345. I don't control the extensions. All files are plain text. I want OSX to open any file extension that it hasn't seen before with my favorite text editor when I click on it. Or even better set up file association defaults for extension patterns ie textEdit for extensions matching *.o*. I do NOT want to create file associations for individual files since this extension will only ever exist once, and I do not want to go through the process of selecting the application to use for each file. Thanks for any help you can offer.

    I am try to deploy a jar to an jboss server. It works on my environment. But when I deployed the same jar on another server, i kept getting an error saying that the persistence unit is already registered. There is no other bean using the same name and the same persistence unit name. I tried to restart the server and remove the tmp, work, data directory but still get the same error. here is my error: ObjectName: jboss.j2ee:service=EJB3,module=wess_jpa.jar State: FAILED Reason: java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:unitName=dses_wess already registered.

  • Enabling mod_rewrite on Amazon Linux

    - by L. De Leo
    I'm trying to enable mod_rewrite on an Amazon Linux instance. My Directory directives look like this: <Directory /> Order deny,allow Allow from all Options None AllowOverride None </Directory> <Directory "/var/www/vhosts"> Order allow,deny Allow from all Options None AllowOverride All </Directory> And then further down in httpd.conf I have the LoadModule directive: ... other modules... #LoadModule substitute_module modules/mod_substitute.so LoadModule rewrite_module modules/mod_rewrite.so #LoadModule proxy_module modules/mod_proxy.so ... other modules... I have commented out all the Apache modules not needed by Wordpress. Still when I issue http restart and then check the loaded modules with /usr/sbin/httpd -l I get only: [root@foobar]# /usr/sbin/httpd -l Compiled in modules: core.c prefork.c http_core.c mod_so.c Inside the virtual host containing the Wordpress site I have an .htaccess containing: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress The .htaccess is owned by apache which is the user apache runs under. The apachectl -t command returns Syntax OK What am I doing wrong? What should I check?

  • Stuttery 1080p playback on decent system

    - by Leo
    We have a media center system that was recently built. It works well for all types of content, however it has issues with 1080p content. 720p plays fine. I have tried VLC, ffdshow and finally, CoreAVC. CoreAVC plays the best however it still eventually loses sync due to stutter - this does not happen on other systems with the same file. Specs: Asrock 4core-2dual sata PCI Express ATI 2400 HD 1.5GB DDR 2100 Intel Pentium E5300 120GB Maxtor Diamondmax PATA Any ideas?

    I tried with Suse 11 (KDE), Xubuntu 11.10 and Lubuntu 11.10 and these systems only recognizes 800Mhz from my processor of 2Ghz! The utilities I used are: linuxinfo, sysinfo, "system profiler and benchmark". And all of this only shows 800Mhz My system specs are: AMD Turion 64 Mobile MK36 512 RAM nVidia Geforce Go 6150 (I also tried with nVidia restricted drivers) 120GB Hard drive The weirdest thing is that Windows XP and 7 recognize the 2Ghz of my processor, What can I do? p.s. (It is not just the value of 800Mhz, I also feel my system very slow with linux)

  • What's the difference between DisplayPort, DVI and HDMI?

    - by Leo Bushkin
    As an end consumer, are there any significant differences between the newer DisplayPort interface and DVI/HDMI that I should be aware of? I realize they are different connector types and require compatible equipment, I'm primarily interested in whether there are functional or performance benefits of one technology over another. Should I have a preference for one technology or another on newer video card equipment?

  • Want shortcut to OpenVPN GUI connect in Windows 7 (without going through the system tray)

    - by Leo Alekseyev
    I am running OpenVPN with OpenVPN GUI under Windows 7 x64. Currently, to connect I need to right-click the OpenVPN icon in the system tray and select "connect", which brings up the password prompt. What I want: some sort of a batch file or a shortcut that can be invoked to initiate OpenVPN connection. Motivation: I prefer running my system keyboard driven; I usually hide my taskbar and don't like needlessly fishing in the system tray. Currently, OpenVPN is the only program that forces me to interact with the taskbar. Surely there is an alternative approach, possibly invoking some command line trickery and/or autohotkey, but so far I haven't been able to find it.

  • Mail sent from local Postfix marked as "possible phishing" in Outlook

    - by leo grrr
    Hi folks, Sorry for the newbie question--this is not my area of expertise by a long shot. I work at a small development shop and we finally got around to doing code reviews. (Yay!) I set up an instance of Review Board -- an open-source code review tool -- on one of our local servers but it doesn't seem to like talking to our hosted Exchange server to send notification emails. I decided to just install Postfix on that same box and send mail from localhost, which is working much more reliably, but Outlook disables all links in the email announcements and marks it as possible phishing. What is making these emails look suspicious and what can I change? Would the best thing be to figure out how to relay to Exchange from Postfix? Thanks!

  • What's the behaviour when opening a group of files at once?

    - by Leo King
    I selected a group of .odt files, right-clicked the first one and selected open. I would have thought they would open in alphabetical order, but as the second screenshot shows, they're not - the one with "2014-11-13" opens before "2013-10-23". And then when I select the whole group and press Enter, they open in order - and sometimes they don't. What's the behaviour when you right-click and open for a batch of files? Does it start with the one you selected and pick random files in the list to open next?

  • WD: UDMA CRC Errors and Reallocated Sector

    - by Leo White
    I got a WD Caviar Black 1TB (WD1001FALS) and according to SMART, I got: one "Reallocated Sector" one "Reallocated Event" 26 UDMA CRC Errors in my drive but it's a "Pass" for the "SMART overall-health self assessment test". I think it's because of these, I'm having problems with Grub, and thus can't boot into any OS at all. Are these problems serious? According to "Warranty Services", my drive is still "In Limited Warranty". Would I be eligible for a replacement? FYI: I'm running Ubuntu 11.10. Any help will be appreciated. Thanks

  • Got root, now how should I configure my server?

    - by L. De Leo
    I've been a developer for years and by trade I had to know a little bit of server side configuration. But now I find myself needing to manage my own VPS instance (Amazon EC2) and I'm lost. I'd like to know what are the common ways to configure an Apache and MySQL server that is secure and efficient. For example right now I'm doing everything as root but I doubt that's the best way at all. My whole Apache is configured to serve 1 site when I'd like it to be able to serve multiple sites. Where do I start?

  • Host to set up postfix to use external smtp server

    - by Leo
    I have a web server and a mail server. Both have the same domain name except, one points to mywebsite.com and the other is mail.mywebsite.com. They have different IPs. I'm trying to set up postfix on my web server so it uses my mail server as the server that sends e-mails. I followed this guide: http://www.howtoforge.com/postfix_relaying_through_another_mailserver I am getting this error in my logs: Oct 28 02:56:45 mywebsite postfix/smtp[1660]: warning: host mail.mywebsite.com[xxx.xxx.xx.xx]:25 greeted me with my own hostname mywebsite.com Oct 28 02:56:46 mywebsite postfix/smtp[1660]: warning: host mail.mywebsite.com[xxx.xxx.xx.xx]:25 replied to HELO/EHLO with my own hostname mywebsite.com I've searched around and I read that you can't use the same hostname when relaying to a separate smtp server. Is there a work around for this? Do I need to set up my mail server with a separate domain name? Also I have my MX records set up for both mywebsite.com and mail.mywebsite.com. I'm not that experienced with this so if I need to give more info let me know. Thanks!
