Presidential blues got you down?  That ceremony today sure was something!  How about settling down and decompressing with a nice comic book?

Renato Jones?  He's a 1%er that has the funds, access, skills, and motivation to undertake a killing spree to make the motherfuckers pay.  American revenge comic pulp doesn't get any better than this...absolutely cathartic.  Recommended!

I rather like the disqus 404 page:

(also if you refresh it, you'll get different backgrounds)

I made some textures with a synthesizer in sub-zero temperatures. Pretty fun, even with just a small number of starter modules...

Seems legit...

I had forgotten just how dark and horrifying this show could be at times...

So my lovely 40+ year old Raleigh Record finally gave up and died a couple weeks ago.  :(

The fork developed a crack and probably caused the bend in the down tube.  Pretty unfixable.  FAREWELL to my first commuter in Portland...that $90 investment served me well over the last decade or so.

And now comes the time to figure out a new ride.  With the help of a friend, I've decided to do a custom build.

It's quite far from done...but what strikes me most is just how much this process feels exactly like the first time I built a computer from components!  Spending hours flipping thru parts guides, reading reviews, comparing specs, comparing vendor prices, trying to squeeze everything into some unrealistic/imaginary budget, stressing about forgetting some critical minutiae, discovering what parts are compatible with other parts (or not)...dreaming about what the finished thing will look like and fantasizing about how it may perform...

The process is so similar...and surprisingly rewarding.

I have lots to learn about the build itself, and it's exciting to be out of my element (and a little scary).

What's not to love about lath and plaster wall work?  Cut a simple hole and get all kinds of surprises...

I'm not entirely sure why this cracks me up so much, but I was cutting up some audio for a futel project and accidentally created this mess.  Enjoy my sloppy mistakes and giggle with me...

On more than a few occasions, I've wanted to be able to software-record the sound coming out of my computer speakers.  Many users faced with similar problems resort to using pulseaudio as their sound system, which is reasonble, because it provides a very extensible/pluggable framework for sound.  Unfortunately, my experience with pulseaudio in the past has been "meh", probably due in large part to my heavy use of Pd.  So I've stuck with ALSA through the years when doing simple stuff, resorting to jack when doing more complicated routing between applications.  Simply recording what's playing seems simple enough...right?  Not so much...

I guess some (nicer?) sound cards provide a built-in hardware recording channel that can mix back in the currently playing audio.  Most built-in ones, like the one in my aging T410, do not.  After some sleuthing, I discovered that ALSA's plugin system does, in fact, provide a way to do this.  I'll describe the process here, but it's basically ripped from this thread where kokoko3k serves up the right approach:  https://bbs.archlinux.org/viewtopic.php?id=147852

There's an ALSA kernel module called snd_aloop that "provides a pair of cross-connected devices, forming a full-duplex loopback soundcard".  With just a little fiddling, you can create a "looprec" device that has loops back the audio output into a new recordable ALSA device.  The steps, just like in the above-mentioned post, are:

1. $ sudo modprobe snd_aloop
   (this inserts the relevant kernel module into the kernel)

2. create/edit ~/.asoundrc and paste in the following (a bit of alsa black magic):

   pcm.!default {
     type asym
     playback.pcm "LoopAndReal"
     #capture.pcm "looprec"
     capture.pcm "hw:0,0"
   }
   
   pcm.looprec {
       type hw
       card "Loopback"
       device 1
       subdevice 0
   }
   
   pcm.LoopAndReal {
     type plug
     slave.pcm mdev
     route_policy "duplicate"
   }
   
   pcm.mdev {
     type multi
     slaves.a.pcm pcm.MixReale
     slaves.a.channels 2
     slaves.b.pcm pcm.MixLoopback
     slaves.b.channels 2
     bindings.0.slave a
     bindings.0.channel 0
     bindings.1.slave a
     bindings.1.channel 1
     bindings.2.slave b
     bindings.2.channel 0
     bindings.3.slave b
     bindings.3.channel 1
   }
   
   pcm.MixReale {
     type dmix
     ipc_key 1024
     slave {
       pcm "hw:0,0"
       rate 48000
       #rate 44100
       periods 128
       period_time 0
       period_size 1024 # must be power of 2
       buffer_size 8192
     }
   }
   
   pcm.MixLoopback {
     type dmix
     ipc_key 1025
     slave {
       pcm "hw:Loopback,0,0"
       rate 48000
       #rate 44100
       periods 128
       period_time 0
       period_size 1024 # must be power of 2
       buffer_size 8192
     }
   }
   

That's it!  Your recording software should now have a device available called "looprec", and if you record from it you'll get whatever is playing on your speakers.  You can make this permanent by adding the snd_aloop module to /etc/modprobe.d/sound.conf.

Since you've made it this far, I'll share what I was trying to record:  http://websdr.ewi.utwente.nl:8901 -- which is pretty much the raddest thing ever.
