  • cannot install matplotlib, freetype2 headers are ignored

    - by tgraf
    I want to install matplotlib via pip. There is a problem with freetype2.h REQUIRED DEPENDENCIES numpy: 1.6.2 freetype2: found, but unknown version (no pkg-config) * WARNING: Could not find 'freetype2' headers in any * of '.', './freetype2'. Somebody had a similar problem ( How to install matplotlib on OS X?), and it was suggested to install pkg-config first. I did that with macports, but I still get the same warning. I used find to look for the headers, and they are definitely present in: /opt/X11/include/ft2build.h /usr/X11/include/ft2build.h How can I use those files to install matplotlib?

  • How do I diagnose Windows XP failure to automatically suspend on idle?

    - by Software Monkey
    Since upgrading my hardware (mobo, CPU and memory) a couple months ago my computer no longer automatically suspends and hibernates after the configured idle periods. Both functions work just fine manually, but if I leave the computer on overnight it's still active the next morning even though it's configured to sleep after 3 hours and hibernate after 6 hours. How do I diagnose the cause of this?

  • How to access git:// protocol from GitPython

    - by Owais Lone
    I am writing an app to manage git repos using the GitPython module. It works fine for my local repos but I can't get it to work with the git:// protocol. It takes my git://address-to-repo as a directory on my filesystem. Is there a way to initiate a connection with a remote git repo?

  • Lighttpd + django on gentoo 10 seconds to answer

    - by plaetzchen
    I want to run a Django site on a lighttpd with fastcgi on a gentoo machine. Everytime I try to access the site I get a response after more or less exactly 10 seconds. Im using a socket to let lighttpd communicate with my Django site, but a tcp port doesn't help either. Could this be a lighttpd problem?

  • Unpack this directory into your PYTHONPATH?

    - by Gnijuohz
    I want to install qt4reactor so I went to the github page, it says: Unpack this directory into your PYTHONPATH I don't know what that means. I unziped the file and I tried to add the path to PYTHOPNPATH in the .bashrc file like this: export PYTHONPATH=/home/jacos/qtreactor But I can't import it whatsoever. What I want to ask is where exactly is my PYTHONPATH? How can I find that out? What's the right way to do this?

  • What exactly is a Deamon ? ( how to run a root command from apache binded script that uses www-data user )?

    - by user224235
    I am trying to run this command from WSGI script service httpd restart The problem is this command can only be run by root and apache uses the www-data user. it has been said the solution is to use a Deamon Process i suppose the idea is to send the command to a file that will be executed by a script that is considered "root" user.. its difficult to understand why they would call this a Deamon Process and try to scare me. Perhaps it should have been called : proxy process when i got the idea that this was a proxy process.. i thought about adding a line to /var/spool/cron/root that way the cron would execute the command for me. but of course this means i have to get the system time and then add 1 second to it and then add it to that line so cron would execute the command for me as root but my script demands an output instantly. so i suppose i need to create a DEAMON PROCESS that works like the cron. in other words it is a bash file that will execute the command in a plain file.. but will this DEAMON PROCESS be running a while command 24/7 every second ? would that not waste resources ? it only needs to activate itself to check for a command to execute when there is a command to be executed. i mean in PHP and other programming languages.. running a while statement when there is nothing to be executed could waste resources of the server.. so why should a deamon process constantly be listening for anything. i only want it to listen and execute when it is needed. i do not need a process that is constantly listening.

  • Seemingly random 404's for static files in Pyramid project

    - by seth
    I'm running a Pyramid project with mod_wsgi. Some of the files in my static directory (images, stylesheets, javascript) load fine, but others are coming up as not found. The files that are not working are all web fonts (otf, svg, woff and eot). I tried adding a text file into the static directory where the fonts are to see if I could access it, but it also came back with 404. The same text file also can't be accessed when put in the images folder. From what I'm looking at, it doesn't seem to be a permissions issue. Any ideas?

  • Nginx Tornado Combination Causing 502 Bad Gateway Errors

    - by PlaidFan
    We are facing a problem with inconsistent 502 errors and tracking down the reasons has been a very frustrating exercise. We can reproduce the problem by sending several simultaneous requests quickly. The problem is that several is only in the range of 10 to 20 within a 5 seconds (not a typo). So clearly this type of load should be handled easily. We really like the Nginx + Tornado approach but are considering going to a more traditional (e.g. threading) approach because this problem has been very difficult to solve. I was wondering if you a) know how to fix this issue and b) how we can tracked down the culprit(s). The log files simply identify there being a connection refused. We have the same problem as this post: How do I debug a HTTP 502 error? But there is no answer provided on how to solve the problem so I'm hoping you can help because this may be a common issue with this type of setup. Thanks in advance, Paul

  • Django | Apache | Deploy website behind SSL

    - by planet260
    So here are my requirements. I have a website built in Django. I deployed it on Apache Ubuntu. Before there was no SSL involved so the deployment was pretty simple. But now the requirements are changed. Now I have to take a few actions like signup and login behind SSL and present the admin panel and other normally via HTTP. By following the this tutorial I have set-up Apache and SSL and generated certificates for SSL communication. But I am not sure how to proceed, ie. how to serve only a few of my actions through SSL. Below is my configuration. The normal actions are working fine but I don't know how to configure SSL calls. WSGIScriptAlias / /home/ubuntu/myproject/src/myproject/wsgi.py WSGIPythonPath /home/ubuntu/myproject/src <VirtualHost *:80> ServerName mydomain.com <Directory /home/ubuntu/myproject/src/myproject> <Files wsgi.py> order deny,allow Allow from all </Files> </Directory> Alias /static/admin/ "/home/ubuntu/myproject/src/static/admin/" <Directory "/home/ubuntu/myproject/src/static/admin/"> Order allow,deny Options Indexes Allow from all IndexOptions FancyIndexing </Directory> <Location "/login"> RewriteEngine on RewriteRule /admin(.*)$ https://mydomain.com/login$1 [L,R=301] </Location> </VirtualHost> <VirtualHost *:443> ServerName mydomain.com SSLEngine on SSLOptions +StrictRequire SSLCertificateFile /etc/apache2/ssl/apache.crt SSLCertificateKeyFile /etc/apache2/ssl/apache.key <Directory /home/ubuntu/myproject/src/myproject> <Files wsgi.py> order deny,allow Allow from all </Files> </Directory> Alias /static/admin/ "/home/ubuntu/myproject/src/static/admin/" <Directory "/home/ubuntu/myproject/src/static/admin/"> Order allow,deny Options Indexes Allow from all IndexOptions FancyIndexing </Directory> </VirtualHost> Can you please help me out on how to achieve this? What am I doing wrong? I have read a lot of tutorials but honestly I am not really good at configurations. Any help is appreciated.

  • Safe to remove Python2.6 files?

    - by darkfeline
    I'm using Linux Mint 11 (will upgrade soon), and I've noticed that, even though I don't have any python2.6 packages installed with apt, there's a bunch of residual python2.6 files scattered around my drive, including, but not limited to, dist-packages in /usr/lib/python2.6 and various /usr/share stuff. Is there any way to test if these files are still being used? I'm tempted to sudo rm -rf the lot of them, but I'm scared it'll break stuff. Also, does anyone have any idea where these files could have come from? I believe I had python2.6 installed once upon a time, but I made sure to --purge them, so there shouldn't be any trace of them left, right? EDIT: after using a quick script to check all of the files, it appears most of them belong to important packages, so I won't try weeding out the few which I know are probably useless. Although I am curious why so many packages have python2.6 files when I don't even have it installed. These files are not associated with any packages and I'm not sure if they are safe to remove: /usr/bin/ipython2.6 /usr/lib/python2.6/dist-packages/distribute-0.6.15.egg-info /usr/lib/python2.6/dist-packages/easy_install.py /usr/lib/python2.6/dist-packages/IPython /usr/lib/python2.6/dist-packages/ipython-0.10.1.egg-info /usr/lib/python2.6/dist-packages/setuptools /usr/lib/python2.6/dist-packages/setuptools.egg-info /usr/lib/python2.6/dist-packages/setuptools.pth /usr/lib/python2.6/dist-packages/site.py /usr/lib/python2.6/dist-packages/wx.pth /usr/local/lib/python2.6 /usr/local/lib/python2.6/dist-packages /usr/local/lib/python2.6/site-packages /usr/share/man/man1/ipython2.6.1.gz

  • Dangers of the pyton eval() statement

    - by LukeP
    I am creating a game. Specifically it is a pokemon battle simulator. I have an sqlite database of moves in which a row looks something like: name | type | Power | Accuracy | PP | Description However, there are some special moves. For said special moves, their damage (and other attributes not shown above, like status effects) may be dependant on certian factors. Rather than create a huge if/else in one of my classes covering the formulas for every one of these moves. I'd rather include another column in the DB that contains a formula in string form, like 'self.health/2'(simplified example). I could then just plug that into eval. I always see people saying to stay away from eval, but from what I can tell, this would be considered an acceptable use, as the dangers of eval only come into play when accepting user input. Am I correct in this assumption, or is there somthing i'm not seeing.

  • Unable to run Django on Mac OS X

    - by cybervaldez
    I'm working with a Django project on my Mac (running Leopard) and I want to show it to my team. I've already passed the neccessary port forwards from my router to my Mac's LAN IP address but it doesn't work. I've also tried running the XAMPP server since that always worked with my Windows XP computer but it still doesn't work. Whenever I type my > it's showing a Page Load Error. Is this possibly an issue with an Mac OS X configuration that I need to setup first to allow my port forwards to get in? It's my first time to do this with Mac, perhaps I need to configure something else in network preferences?

  • is there a way to tail a log from remote server without using any user credentials?

    - by suhprano
    I run a script tailing a log in a remote server, like so: ssh userx@someip tail -f /data/current.log|python2.7 monitorlog.py There are dependencies and service requirements that disallows me to run the script off the remote server. (DB, ACLs, and path to another service is uses) Is there a way I can tail and monitor a log without using the ssh userx@someip? I thought about generating RSA keys but I think you still need a user to ssh.

  • Get coords of an oval in Tkinter

    - by Baddie
    I can't seem to figure out how to reterive the x,y position of an oval created on a Tkinter canvas using Python via c.create_oval(x0, y0, x1, y2) I understand that Tkinter creates the oval inside the box specified by x0,y0,x1,y2 and if I can get those coordinates that would also work. I need the coordinates to move the oval by an offset equal to the mouse coords and the actual oval.
