Time for a change. Time for a change.

I propose a change in the way our operating systems let us handle file management. I think most of us with more than a few files have been there, backing up some files, reorganizing all the digital baggage. You start a copy process, but it’s about 3 GB so you’re looking around and find another [...]

Little Victories

After weeks of searching I found the source code to an old program I wanted to port to a microcontroller. I think it’d would have helped if I went into the search knowing the name of the program. It was written for X11 on Unix systems. The comments in the code says it was created [...]

Clock, clocking

Just a quick photo of the Ethernet Clock running some quick code I wrote. It’s just grabbing the time from the RTC module and displaying the time. Timing it probably off a little since I get the time, send the digits to the display and then wait 1/4 second, what’s 200-300 ms between friends though?

more /tmp on Mac OS X

I did some more research and finally found out a little more about what happens to /tmp. Actually a bit more about Mac OS X. First, if you’re not paying attention like me, /tmp is a symlink to /private/tmp. In Mac OS X 10.4 Tiger Apple replaced (or began to replace) cron, xintd, init, mach_d, [...]

2k RAM

I was working on the display for my clock Sunday night and started to think about everything the code a little. I’m beginning to think 2k is going to go real fast with DHCP an SNTP buffers, seven segment serial driver, I2C driver, and a little UI. As for the display, it’s made with blue [...]

Microcontroller fun

I bought an Arduino about a year ago (1 Nov 2009 according to my email) and I’ve made some LEDs blink, bought some other bits and driven LCDs, logged GPS coordinates, and displayed the temperature. The Arduino is a nice platform and makes programming the microcontroller nice and easy by abstracting away the ugly details. [...]
