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 […]

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 […]

Weather Station Excitement

August 24th, 2011, 4 Comments

I’ve sort of wanted a weather station for a long time. Lately, the ham radio hobby has intensified that, and I finally got one. When I finally got the serial link cable yesterday, well I was perhaps irrationally excited. Terah accused me of running all around the house while gathering up stuff for it. That […]

A 4-year-old, Linux command line, and microphone

July 30th, 2011, 4 Comments

There are certain times when I’m really glad that we have Linux on the house for our boys to play with. I’ve already written how our 4-year-old Jacob has fun with bash and can chain together commands to draw ASCII animated steam locomotives. Today I thought it might be fun to install cw, a program […]

A Proud Dad

March 16th, 2011, 12 Comments

I saw this on my computer screen the other day, and I’ve got to say it really warmed my heart. I’ll explain below if it doesn’t provoke that reaction for you. So here’s why that made me happy. Well for one, it was the first time Jacob had left stuff on my computer that I […]

Unix Password and Authority Management

January 31st, 2011, 6 Comments

One of the things that everyone seems to do different is managing passwords. We haven’t looked at that in quite some time, despite growth both of the company and the IT department. As I look to us moving some things to the cloud, and shifting offsite backups from carrying tapes to a bank to backups […]

Research on deduplicating disk-based and cloud backups

January 20th, 2011, 20 Comments

Yesterday, I wrote about backing up to the cloud. I specifically was looking at cloud backup services. I’ve been looking into various options there, but also various options for disk-based backups. I’d like to have both onsite and offsite backups, so both types of backup are needed. Also, it is useful to think about how […]

Jacob: 4 Years Old, and Troubleshooting PCs

December 12th, 2010, 2 Comments

Back in April, I wrote about Jacob and I building his first computer together and how it’s running just the Linux command-line interface — no graphics at all. And he loves it. Well, as is often the case with him, his interest in various things waxes and wanes over time. He hadn’t spent much time […]

Jacob has a new computer — and a favorite shell

April 9th, 2010, 41 Comments

Earlier today, I wrote about building a computer with Jacob, our 3.5-year-old, and setting him up with a Linux shell. We did that this evening, and wow — he loves it. While the Debian Installer was running, he kept begging to type, so I taught him how to hit Alt-F2 and fired up cat for […]
