My Week Ending 2019-02-17

Here’s a summary of some of the things I learned and published this week.


You can follow my daily readings as they happen here.  Here are a selected few, with commentary, from the past week.

  • If you think Google Slides is just for presentations, you need to read this post.
  • Wakelet is a very popular curation tool. (I use it for the curation of the #FollowFriday Twitter messages below) This is a tutorial to get started. Check it out to see if there’s something you’re missing then pass it along to others.
  • I do a lot of things wrong in life. Here are 31 more.
  • This was a challenging (at least for me) quiz about Canada’s territories. I thought I would ace it. Spoiler — I didn’t. How about you?
  • Two offerings from Apple that nobody I know uses in addition to the author of the article. Why are they still around?
  • After the Grammy Awards, Drake got his wish.
  • I don’t know about you but I think I’d be embarrassed to be seen with a box of No-Name beer. Even if it is buck a beer. But, it begs a bigger question; it it can be done, why isn’t everyone doing it? My beer of choice is a red beer. Maybe when it’s priced this way?
  • This is going to become increasingly popular with Chromebooks and even traditional PCs shipping with smaller SSD drives. Is that redundant?
  • Arnie McCallum was a legend in Windsor, Ontario education. If you have Super Rex in your library, it came from him. I met him a couple of times.
  • Peter Beens shared the information about this summer festival in Niagara Falls. I think I may go if it all works out.
  • I guess this is inspired by all the stories of people leaving dogs in the car in the summer. It should be a last resort. If you’re going shopping, just leave your dog at home.
  • Maybe not a whole lot new under the sun here but I’m a sucker for reading what we should be doing to prepare students for the future.
  • How can you ignore a story about joy riding bears?
  • Whoops. Google reveals some security secrets via Google Earth. Time to move everything underground?

Opening song this week:

The latest #TWIOE show features blog posts from:


Technology Troubleshooting 

It’s seldom that I confess publically that technology has me beat so mark February 17, 2019 in your calendars.

Do you see the list of people from #TWIOE above? Up until today, that was a bulleted list. I use my vast computer knowledge of highlighting last week’s and pasting this week’s names over top.

And, with the new block editor in WordPress it always screws up. It ends up deleting the original bullet block and creates five bullet blocks, one for each name.

I’ve tried everything I can think of with no success. So, from now on until I notice of a solution, it will just be an unbulleted list like it is today.

Probably nobody but me notices or cares.

I just hate it when a computer gets the best of me.

Whatever happened to …

… the duochrome test?


OK, it’s a stretch but last week’s post about red and green exit signs got me wondering. I appreciate the comments and insights from those that chose to respond to the post.

It got me wondering if the red/black combination had more impact than the green/black combination. That led me back to years ago getting my eyes tested. I’ve worn contact lenses or glasses for as long as I can remember so I can’t recall the last time I woke up ready to go, except maybe for bumping into something I couldn’t see!

But, I do remember for years going to my eye doctor and this test was done every time. What looks “sharper” – the green side or the red side?

Now, I always thought that it was silly because black on green always appears sharper than black on red to me.

I did some research here. Holy physics, Batman.

Before you get overly impressed with me knowing the term “duochrome”, I’ll confess. It was easy to find as a result of the internet search “optometrist test red green”. Now, I can sound semi-informed when I visit my optometrist for my yearly check up. Quite frankly, I can’t remember the last time that the duochrome actually came up as part of my checkup.

For a Sunday, check in please..

  • Before reading this post, did you know of the word duochrome?
  • Do you have a predisposition to black on green or black on red?
  • Do you get your eyes checked annually? If not, why not?
  • When was the last time you had a duochrome test?
  • How many pairs of glasses do you own?
  • Do you think that red/black or green/black makes for a better exit sign?

I’d be most interested in your thoughts and insights on this topic. Please share them in the comments below.

This is part of a regular fun series of posts that appear on Sunday morning. They can all be enjoyed here.
