Welcome to Mr Harshaw’s Students!

Welcome to the Computer Technology, Communications Technology, and Computer Science class!

If it’s related to computers, this is the class to be in!

Here is a presentation I will be reviewing with you to talk about the differences in the three subjects. I’m also sharing a handout that gives an overview of all the subjects in the Technology department.

BTT1O Computer Teardown and Reassembly

This was an amazing successful assignment!

We started by installing Slacko Linux on the computers to make sure they worked, then the students completely disassembled and reassembled them afterwards. For full marks, the computers had to work again!

BDSS E-Waste Recycling Program

Here’s a tweet I posted about an e-waste recycling program I’m coordinating at my school:

If you’re in the neighbourhood and have any hardware you’d like to drop off, please do! The official recycling program runs until May 18 but I’ve already had discussions with RCT about continuing the program on indefinitely, albeit in a more casual nature.

Duplicati Backup Software


At home I’ve been wrestling with what to do for computer backups now that my CrashPlan service is coming to a close (they are phasing out their consumer plan).

I think I’ve found my solution — Duplicati 2.0.

From their website:

  • Duplicati is free software and open source. You can use Duplicati for free even for commercial purposes.
  • Duplicati works with standard protocols like FTP, SSH, WebDAV as well as popular services like Microsoft OneDrive, Amazon Cloud Drive & S3, Google Drive, box.com, Mega, hubiC and many others.
  • Backup files and folders with strong AES-256 encryption.
  • Save space with incremental backups and data deduplication.
  • Run backups on any machine through the web-based interface or via command line interface.
  • Duplicati has a built-in scheduler and auto-updater.

So far I’m very impressed. I’m backing up to an unRAID server I’ve built and it’s working flawlessly.

Two-Pizza Rule

Here’s an interesting article I found about how Jeff Bezos, Amazon’s founder, runs a meeting. Check it out to learn about his two-pizza rule, about how he doesn’t use PowerPoint presentations, and why his meetings start in silence.

What do you think of his method? Would it work in your environment? Why, or why not?

(For the record, I never use PowerPoint either. I use Google Slides!)
