Complete Guide to Cloning Linux Machines Using “Imaging”

This post describes the process of creating a master machine, making an "image" of that master, copying that image onto a USB bootable drive and the commands needed to clone the master onto target machines. This process was devised by PCF's Jan Deruiter with consulting input from Linux guru/expert Keith Perry from DAO Technologies. One of the reasons we have posted these details is for users to be able to replicate the process for themselves. [...]

A Word About How We Prep Computers For Deployment

Over the years, PCF has "refurbished" and "imaged" thousands of computers that were given away to schools, other programs/organizations and to families directly. In this post, we thought we'd describe what's involved in doing so. The first step is for us to procure the equipment. We are lucky to have generous donors donate their computers to us. Companies might donate hundreds of machines at a time and individuals often donate one or two. PCF then [...]

PCF Donates High-End Computers to Lankenau High School

Virtually all of the thousands of computers PCF has donated to families, schools and other programs over the years, were donated to us. And the process is fairly straightforward: individuals or companies donate the computers, we wipe the data, refurbish them as needed, put Linux on them and then gift them to whoever with matching chargers, power cords, monitors, etc. In the early days, we would have to wire them up (switches, routers, etc) for [...]

XL Donation by Carpenter Tech. Funds 3D Printer Lab at Logan (and others)

One of the schools that benefited was Logan Elementary, a school PCF has worked with for years. PCF donated [...]

PCF Support of Emlen’s Play Days and Parent’s Days

For years now, PCF has helped out Emlen Elementary during their Parent Orientation day at the beginning of the year and their Students Play Day held just before summer break. Both events involve cooking a massive number of hotdogs...like 450 of them for each gig! PCF is lucky to be able to recruit neighbor volunteers for these events. "Henny" and "Rick" both have helped us with these events. In fact, Henny brings her griddle each [...]

PCF Revamps Houston’s Auditorium AV System

Take Home Computers for Remote Learning

After the first school district shut down back in April, many of our partner schools approached PCF for help. While the district had provided a large/huge infusion of Chromebooks, there were not enough to go around and in some cases, schools were reluctant to empty out their classroom inventory in fear of equipment loss or damage upon the students' return to school (some day). There was a lot of uncertainty and some schools simply did [...]
