So at some point I need the voice dictation client to be able to do basic interactions with applications on the desktop (think typing text and the like). So how do I go about doing that? I want to be compatible with Wayland when it shows up, but still work on X (since that's where ...

I spent the day working on Listener. The bulk of the work was just cleanup, getting TODO items set up, fixing the setup script, etc. The actual task of voice dictation didn't get moved very far (I got a trivial "correct that") event working, but it doesn't actually make anything happen.

I also started ...

So you have an audio stream where you'd like to get a human-friendly readout of the current audio level. You add a level component, but how do you actually get the level messages it generates?

            bus.add_signal_watch()
            bus.connect( 'message', self.on_level )

It really seems that you *should* be able to use element.connect(), but there doesn't seem ...

So you have an internal device the web-gui of which you want authenticated users to be able to access.  You've got nginx running on the front-end server. You're willing to open up a port on the outside firewall, but all access on that port needs to go through your main web-app's permissions. You setup an ...

So the source of the segfaults that I'm seeing on fglrx and FreeGLUT on Kubuntu 14.04 has come to light. It's a known issue with the registration of FreeGLUT and fglrx at-exit handers (at the C level). You can work around it in your own code with PyOpenGL 3.1.0b3+ (which is still pending release) using: ...

Since this was a bit of a pain to track down, here's the process, on an Ubuntu Server 12.04 machine, to create many ALSA dummy devices:

$ cat /etc/modprobe.d/alsa-dummy.conf 
options snd-dummy enable=1,1,1,1,1,1,1,1,1,1,1,1 pcm_devs=4,4,4,4,4,4,4,4,4,4,4,4 fake_buffer=0,0,0,0,0,0,0,0,0,0,0,0
$ modprobe snd-dummy

That sample creates 48 dummy devices (on 12 cards), though that's likely more than you'll ever need.  The ...

So you have a Dell Ubuntu 14.04 Laptop and it is running way too hot. You can configure it to run at a reasonable level using i8kmon. As with anything heat related, be careful. If you miss-configure the machine you are likely to wind up with a fried machine!

You create a file called /etc/i8kmon.conf and put the ...

So I've pretty much given up on the laptop having fglrx running properly, current Ubuntu just doesn't get fglrx, sucks, but okay, I should have stayed on LTS if I wanted a working machine.  But now LTS Kubuntu fglrx is hosed after some system update.  Every attempt to run any OpenGL program just segfaults (not ...

So the AMD Proprietary driver (fglrx) for Linux supports "Ubuntu 12.04 and 13.04" (Note: not the current Ubuntu 13.10), and so far every attempt I've made to use them on 13.10 has supported the "not supported" hypothesis (kernel module compilation failures in the latest iteration).  But drat-it-all my machine meets the declared software requirements (kernel, ...

Apparently I'm blessed with a Voice Dictation friendly accent and tone. I can pretty much use most Voice Dictation systems, including the ones on Android, Dragon Naturally Speaking, and PocketSphinx. The results aren't mind-blowing-ly good, but if it's quiet and I speak clearly and train anything that gets missed, I get reasonable results.

Watching a ...
