Dancer talk at YAPC::NA 2012

by on Jan.24, 2012, under Dancer web framework, Perl

Mark Allen will give a talk at YAPC::NA 2012 on the Dancer Perl web framework he describes as:

This talk presents the Dancer web framework beginning with “Hello World” and progressing through a couple of easy to digest introductory applications. All of the primary Dancer features are presented including URL routing, writing handlers, and output templating. A selection of useful and common Dancer plugins will also be covered. This talk is best suited for beginning and intermediate Perl programmers.

(via JT Smith, in turn via the YAPC::NA blog.)

I hope it’s recorded, as I’d like to see it, but won’t be able to afford to attend YAPC::NA.

VLC getting proxy settings via gconf

by on Jan.23, 2012, under Linux, System Administration

I had a problem with VLC, using outdated proxy settings rather than connecting directly, even with no proxy configured in VLC’s settings (and even when trying to override it using command-line options).

(It would show that it was trying to use a proxy:

[0x134b4b0] main access error: connection failed: Connection refused
[0x134b4b0] access_http access error: cannot connect to supernova:3140

(supernova:3140 was the proxy setting it was picking up.)

After using strace to follow the execution of VLC when trying to play a network stream, I realised it was getting the settings via gconf; I needed to execute gconf-editor, navigate to system, http_proxy, then untick use_http_proxy – and also edit the value of the host setting to an empty string (without doing this, VLC ignored the use_http_proxy setting being false, and tried to use the proxy anyway!).

I could have done the same using gconftool-2 with:

gconftool-2 -s /system/http_proxy/use_http_proxy --type bool false
gconftool-2 -s /system/http_proxy/host --type string ''

Blogging for my own future reference, and for anyone else who’s using vlc on XFCE and wondering where it was getting the proxy settings. I’ve used Gnome 2 on this machine before, and I think that system proxy setting was set by Chromium (Google Chrome).
