Tuxedo.
So I wanted to set up my demo to be available at a friendly local URL when I run it tomorrow, so I decided to check out how avahi is doing these days.
sudo aptitude install avahi-server
Then edit /etc/avahi/avahi-daemon.conf
host-name=<yourhostname>
Restart avahi and your server will show up as <yourhostname>.local (or something similar, if ...

Realized this morning that I offered to do a quick talk on how to get video running on your web-site at the Django Toronto tomorrow. So I've put together a small demonstration that shows creating HLS and RTMP streams (using nginx-rtmp), and a quick demo showing how to push to the server using a video-for-linux ...
Do I really need 0-copy?

Nginx Upload Module's key feature/optimization is that as nginx streams the multipart post to disk, it directs the embedded files directly to separate file handles, you can then just move those files to the final location. So far everything I've seen to replace it has at least a couple of copies going on, as they ...
Generic Filter/Sort Tables for Django?
Written by

Snaking,

So this came up (again). Users want to be able to look at a (largish) set of records in Django (millions of records) and do the following:
- click columns to sort by field values (with indication of sort direction, of course)
- filter by column values (include, exclude, greater-equal, less-equal); that is, they want to click ...
Compress your JS/CSS in Django

Finally integrated webassets (django_assets) into our build process. Very nice interface (using the template-only approach). And other than a few issues with our pyc-only deployments, it pretty much "just worked" once I realized that adding the staticfile-finder for the development server is a critical requirement.
The changes to your settings look like this:

Lazy Caching Proxy Results in Nginx
Written by

If you are using nginx as your front-end server for Django, you can also use it as a proxy cache (for smaller websites). You configure the cache like so:
proxy_cache_key "$scheme://$host$request_uri"; proxy_cache_path /var/blog/cache levels=1:2 keys_zone=blogcache:120m; proxy_temp_path /var/blog/proxy; proxy_cache_valid 200 302 5m; proxy_cache_valid 404 1m; proxy_cache_use_stale updating; proxy_cache_bypass $cookie_sessionid; proxy_no_cache $cookie_sessionid;
The proxy_no_cache and proxy_cache_bypass lines ...

Blog Rebooted
Written by

Vindaloo.
I've moved the blog onto its own VPS, running Zinnia (a Django based blog platform). It's using the Zinnia Bootstrap theme, and hopefully most of the old content will have ported over properly. The server has a (free) SSL certificate, so you can, should you wish, browse or comment using SSL (I really can't imagine ...
Playing with EGL platform for PyOpenGL
Written by
on
in
Snaking.
Played around a bit today with generating an EGL wrapper (for mesa-egl). No real reason for it, other than I wanted to see what EGL is like. One thing that shows up is that the current idea of a "platform" in PyOpenGL is a little too limited. EGL is cross-platform, and apparently can work with ...
