If this happened at home, I could use a serial console cable, or plug the Pi into the spare HDMI port on my monitor and use a USB keyboard, or attach a USB SD card reader to … Continue reading I Broke My Pi’s Networking!

For example, when using Duo for SSH-based git push and git pull there's no Duo prompt, it only works with Duo push, and you have to … Continue reading Yubikey PIV for SSH on Macs

The Nexus Q doesn't really have any impact on IT, and it's an odd system: it costs over 3 … Continue reading Google I/O 2012

The class is taught by AWS Solutions Architects, rather than by dedicated training staff, so the instructors have real, practical experience with helping customers use AWS; the SAs use that experience, and feedback from each class, to continually improve the class. The class covered … Continue reading Architecting with AWS Training
I went to my third (of three) Breaking Development Conference in April - this time it was in a biodome in Orlando, FL. Following on from the themes of the previous conferences, a large part of the conference was focused on responsive web design (RWD). RWD was proposed as a widely applicable solution at the … Continue reading Breaking Development, April 2012
