More history of Lego robotics
by Evan Koblentz 14 Jun '19

Although my website is about Lego robotics from before the Mindstorms era, I decided it's useful to document early Mindstorms development at MIT. So check out the new "Making 'Storms" section ... http://www.mindsbeforethestorm.com ... there are also many small update since the last time that I posted about this.

We've been invited for a tour of the Princeton U. data center. There is no set time; it's up to us to organize something. Is anyone interested?

[Slightly OT] Need suggestions/ help
by laurakid 12 Jun '19

12 Jun '19

As some of you may remember me mentioning around last years Festivus, I have been overwhelmed by my (not so) current tech. I have had security issues, trouble with adjusting to and backing up/ restoring from multiple platforms and devices. I am keeping it vague to keep it short. Basically, I could use help from someone who would have the time and capability to help me regain some control over my data and create a current setup that is secure and meets my needs. I was thinking this could be a good freelance gig for a kid looking for summer work? Any suggestions on how to approach this problem are appreciated.

OT: Grub question
by Evan Koblentz 12 Jun '19

I wanted to wipe one of my spare older PCs. I used an MS-DOS boot disk and ran fdisk. That worked for zapping the partition, but it left behind Grub when I reboot. How do I delete that?

Museum reports
by Evan Koblentz 12 Jun '19

A handful of visitors today, including one guy from Kansas and a couple who last visited a year or two ago. Between visitors, I worked on some VCF West business and also some personal projects. Steve A. came by to pick up our Digicomp 1 (our second) because he has expertise in restoring those.
