stateless booting

A problem I’ve been working on dealing with for a while has been the sad … well … no … terrible state of programmatically configured Linux systems, where the state is determined from a central (set of) source(s) via configuration databases, and NOT by local stateful configuration files. Madness lies in wait for those choosing […]

Systemd, and the future of Linux init processing

An interesting thing happened over the last few months and years. Systemd, a replacement init process for Linux, gained more adherents, and supplanted the older style init.d/rc scripting in use by many distributions. Ubuntu famously abandoned init.d style processing in favor of upstart and others in the past, and has been rolling over to systemd. […]

Starting to come around to the idea that swap in any form, is evil

I tried the nodejs version and … well … it was horrible. Basic things didn’t work. Made life very annoying. So, being a good engineering type, I wrote my own. It will be up on our site soon. Here’s an example ./influxdb-cli.pl –host 192.168.5.117 –user test –pass test –db metrics metrics> \list series .———————————-. | […]

Doing what we are passionate about

I am lucky. I fully admit this. There are people out there whom will tell you that its pure skill that they have been in business and been successful for a long time. Others will admit luck is part of it, but will again, pat themselves on the back for their intestinal fortitude. Few will […]

Yay, latest Java update broke Supermicro remote console

JRE 7 u 51. Self signed Java console applet. Let the hilarity begin. I tried uploading our own cert and key to the unit. No luck. Its the applet the needs to be re-signed. This is the joyous message that awaits: Of course, the IPMIview tool sorta kinda works. Though its useless for remote support […]
