Finally got around to introducing what I've been working on for the past couple of years (for those who haven't heard about it already). Full post: http://kpreid.livejournal.com/52312.html

ShinySDR (why yes, I am terrible at naming things) is a software-defined radio receiver application.

Specifically, it is in the same space as Gqrx, SDR#, HDSDR, etc.: a program which runs on your computer (as opposed to embedded in a standalone radio) and uses a peripheral device (rtl-sdr, HackRF, USRP, etc.) for the RF interface. Given such a device, it can be used to listen to or otherwise decode a variety of radio transmissions (including the AM and FM broadcast bands everyone knows, but also shortwave, amateur radio, two-way radios, certain kinds of telemetry including aircraft positions, and more as I get around to it).

ShinySDR is basically my “I want my own one of these” project (the UI still shows signs of “I’ll just do what Gqrx did for now”), but it does have some unique features. Have a look at the README on GitHub for details: https://github.com/kpreid/shinysdr

robot: anthropomorphic automaton
songbird: arboreal artist
storybook: amazing adventure
textbook: authoritative algebra
birdhouse: architectural aviary
chemistry: academic alchemy
tin: antique aluminum
bronze: archaeological alloy
neon: amber ambiance
divide: antagonistic arithmetic

The program word2vec [1] turns words from a corpus of text into vectors living in a vector space of a few hundred dimensions.  The idea behind the program is to think of each word as a collection of attributes that can be added to and subtracted from each other; for instance, the KING - MALE is very close to MONARCH and MONARCH + FEMALE is very close to QUEEN.

My brother +Douglas Summers-Stay took a list of words he wanted definitions for, then found the nearest vectors that were the sum of an adjective and a noun both starting with the letter "a".

Because the vectors are word-based instead of context-based, it can't tell the difference between all the meanings of a word, so the results often end up punning on all the meanings.

Love it! Such attention to detail.

“William Kahan orders a 14.625 ounce coffee. He receives 15 ounces of coffee in a 16 ounce cup. He complains that the error is greater than one gulp.”

“Nick Bostrom walks in and orders coffee that has successfully passed through the Great Filter.”

I have been really enjoying literarystarbucks.tumblr.com, which publishes complicated jokes about what famous authors and fictional characters order at Starbucks. I like it so much I wish I knew mo...

My interactive presentation on digital signal processing is now available on the web. Annoy your neighbors whistling into your microphone!

More details, source code, etc. at the site.

Crosspost: <http://kpreid.livejournal.com/52068.html>
A Visual Introduction to DSP for SDR. This is an animated slide deck providing a tour of digital signal processing topics relevant to implementation of software-defined radios, focusing on building visual/geometric intuition for signals. Topics covered: Complex (IQ) and analytic signals.

In the 1930s and 1940s, decades after steam engines had made wind power obsolete, Dutch researchers obstinately kept improving the – already very sophisticated – traditional windmill. The results were spectacular, and there is no doubt that today an army of ecogeeks could improve them even further. Would it make sense to revive the industrial windmill and again convert kinetic energy directly into mechanical energy? The Netherlands had 5 times mo...

“This reminds me of a silly idea I had when I was younger. It’s about Star Wars (of course). Specifically it’s about a possible rule—or design principle—underlying the kitbashed used-universe design of that galaxy far, far away.”
I have a bad feeling about this.

Motion sensing using the doppler effect. Recently I stumbled upon an interesting paper for implementing motion sensing requiring no special hardware, only a speaker and mic! Unfortunately the paper didn't include code to test it, so I decided to reproduce it here on the web!
