Virtual Machine Testing

A while back I built a machine for hosting VMs. It’s not super awesome, but it should be capable. It has a 4 core Sandy Bridge Xeon (E3-1220, 3.1 GHz) 8gb of memory (2 dimms with room for another pair) and no disk. It boots from a 4 or 8 gb Kingston USB flash drive. [...]

Uptime down

Well my little Solaris running mini itx system finally no longer has a giant uptime. At about 779 days and 45 minutes the power went out for about 5 seconds bringing this mini system’s big uptime to an end. That’s what I get for connecting a temporary system to wall power I guess…because in IT [...]

Uptime

Yesterday around 4:30 pm an old HP DL360 G3 server running Solaris turned 1500 days of uptime. $ uptime 3:00pm up 1500 day(s), 21:43, 2 users, load average: 0.00, 0.00, 0.00 It’s getting close to hitting 1501. That however will be it. I’m going to reboot it later today to confirm some network configuration changes.

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 [...]

IR Sensor network.

I was thinking about making a sensor network. I considered just making every sensor fat with Ethernet. Ethernet modules run around $25 + $0.50 for a MAC address eeprom. That can really add up fast if you have no budget. Then there are ip addresses, configuration code, local interfaces, cables, and power, and wait…a cable, [...]

Don’t Panic

Scott over at Mostly Networks has a good post on keeping calm in stressful situations. I think I do a good job staying collected under most “emergencies.” Running around without fully understanding the situation doesn’t solve problems. Stabbing solutions in without collecting enough context usually just makes a mess. Sometimes you run into something new, [...]

uptime silliness

A while ago I was upset that DNS queries seemed to be taking a long time at home. I was using an older Solaris bundled version of Bind. I had read there was an issue that could cause slow response times, and things seemed slow, but I’m a Comcast customer and things often seem slow. [...]
