Voice Keying with bash, sox, and aplay

August 24th, 2012, No Comments

There are plenty of times where it is nice to have Linux transmit things out a radio. One obvious example is the digital communication modes, where software acts as a sort of modem. A prominent example of this in Debian is fldigi. Sometimes, it is nice to transmit voice instead of a digital signal. This […]

A Verbose, Hands-On Nexus 7 Review

August 11th, 2012, 14 Comments

Some of you may have noticed that I am not a concise author. Perhaps that has something to do with the fact that I am not a concise reader. I like facts, details, and lots of them. So as a recent Nexus 7 purchaser, here you go. Genesis I’ve long used Android devices, and last […]

How to get started programming?

July 28th, 2012, 10 Comments

I have been asked for advice from several people recently on how to get started programming, or how to further develop a nascent interest in coding or software engineering. The people asking the questions range in age from about 10 years old to older than me. These are people that, for various reasons, are not […]

A Linux-Based RFID Thing Finder

July 19th, 2012, 14 Comments

Sometimes I have things nicely organized. Power adapters for radios in one drawer, for cameras in the next. And sometimes… not so much. Sometimes I’m not sure if things are in the basement or the attic. It seems like technology should be able to help solve this problem, but as far as I can tell, […]

Decisions on Listening to Music

July 8th, 2012, 6 Comments

A couple of days ago, I commented about my thoughts on finding a better way to listen to music, and asked for suggestions. I’ve checked out the avenues suggested, and here are my thoughts so far. Streaming service: Spotify Of the streaming service offerings, Spotify seems the most compelling. It has both Linux and Android […]

How to listen to music?

July 6th, 2012, 12 Comments

This seems like a simple question: how do you listen to music? But in a way, I think I’ve fallen behind the times. I’ve enjoyed listening to digital music for years, since well before MP3 even existed (MIDI files could be comfortably downloaded over dialup; some of you may even remember MOD files). Anyhow, a […]

I introduced my 5-year-old and 2-year-old to startx and xmonad. They’re DELIGHTED!

June 20th, 2012, 134 Comments

Two years ago, Jacob (then 3) and I built his first computer together. I installed Debian on it, but never put a GUI on the thing. It’s command-line, and has provided lots of enjoyment off and on over the last couple of years. I’ve written extensively about what our boys like to do, and the […]

Windows & a dying hard disk: Solving with Linux

June 14th, 2012, No Comments

Today, my workstation sent me this email: The following warning/error was logged by the smartd daemon: Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors and then a little later, this one: The following warning/error was logged by the smartd daemon: Device: /dev/sda [SAT], 1 Offline uncorrectable sectors From the hard disk’s SMART data, this is […]

How to debugging Linux failure to resume from suspend?

June 14th, 2012, 17 Comments

I’m running a computer with a Gigabyte Z68A-D3H-B3 motherboard, and have never been able to get it to properly resume from suspend to RAM in Linux. It has worked fine on the rare occasion I’ve tried it in Windows 7. My somewhat limited usual for debugging aren’t particularly helpful. The system appears to suspend perfectly […]

XMPP for Children

February 11th, 2012, 8 Comments

When Jacob was just born, I wondered how I might introduce them to computing. I thought over various things, but that wasn’t really the most pressing thing right then. I don’t suppose that I could have predicted installing an XMPP IM server (Prosody) for the boys. And I certainly couldn’t have predicted creating accounts named: […]
