G2X connecting in developer mode

January 7, 2012
Tags: , , , , ,

On Fedora, I was having issues getting my T-Mobile G2X to connect in developer mode.
For sure, I was setting Settings-Applications-USBdebugging to Checked. And when plugging in the device, the SD card (and/or) internal memory space was showing up on the desktop (and the output in /var/log/messages looked equivalent to that from my working G1) [...]

MythBackend service not starting

November 25, 2011
Tags: , , ,

/var/log/messages complains :

Nov 24 23:52:54 myth systemd[1]: mythbackend.service: control process exited, code=exited status=235
Nov 24 23:52:54 myth systemd[1]: Unit mythbackend.service entered failed state.

Simple solution (not tested whether this survives reboot) :

# touch /var/run/mythbackend.pid; chown mythtv:mythtv /var/run/mythbackend.pid
# systemctl start mythbackend.service
# grep mythbackend

PulseAudio default Sink (output)

November 24, 2011
Tags: , ,

MythTV suddenly stopped audio (yet again : Every upgrade the reason is different). This time, it appears that the order the audio cards are detected has changed, so the default output has changed…
The following is relevant to the process (haven’t tested this through a reboot, yet) :

$ pacmd help
$ pacmd info  | grep -i [...]

Building uwsgi from src.rpm without Python 3

November 16, 2011

To build uwsgi on Fedora 12 (which has no easy-to-find python3 rpm), run through the rpmbuild process (shown in a previous post in more detail for nginx) and make the following changes :

wget http://kad.fedorapeople.org/packages/uwsgi/uwsgi-0.9.9.2-2.fc15.src.rpm
rpm -ivh uwsgi-0.9.9.2-2.fc15.src.rpm
rpmbuild -bb  ~/rpmbuild/SPECS/uwsgi.spec
yum install python-devel libuuid-devel jansson-devel libyaml-devel ruby-devel python3-devel python-greenlet-devel  lua-devel  ruby
# NB: python3-devel doesn’t exist…

Updating nginx (with uwsgi) for Fedora 12 from src.rpm

November 14, 2011

In order to get access to uwsgi (useful for deploying python flask projects, for instance), one needs a version of nginx > 0.8 or so. But Fedora 12 doesn’t have such a modern version : Here’s how to build it from a src.rpm from a more recent Fedora release.

# First, make sure [...]

Compiling nginx (with uwsgi) for Fedora 12

In order to get access to uwsgi (useful for deploying python flask projects, for instance), one needs a version of nginx > 0.8 or so. But Fedora 12 doesn’t have such a modern version : Here’s how to compile it from source :
Actually, a less hacky approach is to simply back-port (trivially) [...]

Building a Python LibreOffice Extension

October 7, 2011

Here’s a pretty minimal setup for building an extension for LibreOffice in Python.
Working backwards, I’ve called the extension ‘mdda_fns.oxt’. Here’s the makefile, which is in the root of the package development tree :

all:    clean zip install
clean:
        unopkg remove mdda_fns.oxt
        rm mdda_fns.oxt
       
zip:

MythTV / lircd updates on Fedora : Hauppauge

July 16, 2011

I’ve been maintaining a PVR350 on an old Dell 2.4GHz since forever.
Latest updates (to MythTV 24.1, and licrd 0.9.0.7) have made big changes. But it’s all working again, including a serial IR blaster. The following is just for my easy reference, and anyone else who now finds their Grey Hauppauge remote [...]

nginx and WSGI using Paste

July 13, 2011

Paster contains the WSGI server originally incorporated within CherryPy (see http://pythonpaste.org/script/module-paste.script.wsgiserver.html). Funnily enough, this is a pretty hot contender amongst other Python WSGI webservers (see http://nichol.as/benchmark-of-python-web-servers) : Maybe not the best, but because of its ease of set-up (working out-of-the-box for Pyramid and Pylons) it is extremely compelling.
Combining it with NGINX makes for a [...]
