Something that’s been annoying me ever since I started using a new Windows 10 desktop is that every time I would open my Downloads folder, which usually contains several hundred random items inside, Windows would take upwards of 5 seconds each time to sort the directory by date. This was the first time I had ever seen behaviour like this, and although my first instinct was to think the number of files in the folder was slowing it down, a couple hundred files is virtually nothing. After flipping through several windows forum posts where “expert contributors” were suggesting everything from virus scans to full re-installs I came across one single post that had the killer detail I was looking for. That detail was make sure the column you are sorting is “Date Modified” and not just “Date”. If one was not looking closely it’s easy to see how this could be missed, and if you don’t have both the “Date” and “Date Modified” columns set to be visible, you could just assume that the “Date” column was the Windows default, and the right choice. The explanation given in the forum post is that “Date Modified” is a file attribute attached to the file, while “Date” is not, and thus has to be calculated by Windows every time the directory is opened.

A couple months ago at Muug I did a presentation on the basics of wireless theory and the Canadian regulations regarding unlicensed wireless usage. The first three quaters or so of the presentation covers the wireless theory, including things like decibels, radiation patterns, coaxial cable, fresnel zones, and more. In contrast to most other information sources, the regulations I cover in the last quater of the presentation are those created and enforced by Industry Canada who is responsible for wireless regulation in Canada. If you’d like to have a look at the slides from the presentation, they are availble in pptx and pdf format at the links below.

I’ve sort of lost count, but I think by now I’m on the fifth or sixth iteration of this blog after having it offline for months at a time. This time the blog returns as static HTML compiled with Jekyll, previously it was Wordpress for a couple iterations and hand-written HTML before that. In addition to this blog I’m also starting a ham radio focused blog at VE4WDZ.ca. I’ve also decided to make all the content on this blog that was created by me available under the Creative Commons Attribution-ShareAlike 4.0 International license, which means if you’d like to share or copy any of the information posted here you’re free to do so as long as you give credit and release it under the same license.
