William George Walsh Pethybridge’s military records while serving with the Canadian Expeditionary Force during the First World War

The synopsis page for the Canadian Expeditionary Force’s records for my wife’s grandfather and our son’s great grandfather. The site also provides access to the complete military records for essentially everyone who served in the Canadian forces during World War I (see second link below).

“The mystery of Cape Town’s disappearing gun”

The story of a British military gun from the Victorian era that was designed to immediately disappear when fired (this allowed the crew manning the gun to reload it in relative safety).

The gun eventually disappeared in a somewhat broader sense of the term after it was buried and forgotten when the land that it was on was redeveloped in the 1920s. It was recently rediscovered during yet another redevelopment project.

“Google AI system proves over 1200 mathematical theorems”

An interesting look at what has been accomplished and/or discovered through the use of artificial intelligence in the realm of studying and (sometimes) proving mathematical theorems.

Hat tip to my friend Rod Johnson.

“Researchers Just Demonstrated Nuclear Fusion in a Device Small Enough to Keep at Home”

An interesting article on some recent progress towards (hopefully) eventually being able to build relatively small fusion reactors.

GeoGuessr (website)

If you’re into maps and getting lost, here’s the site for you! GeoGuessr drops you down (via Google Streetview) at some random location somewhere and then hand’s you the map and the keys to the virtual Streetview car. Your job is to figure out where you were dropped by driving around in said virtual Streetview car.

Needless to say, there are a few things to keep in mind:

  • there’s no little blue dot (or anything else) on the map to tell you where you are (there is a white flag on the left side of the Streetview window that you can click to get back to where you were originally dropped off)
  • you get to select which region you want to get dropped into. Being pretty familiar with a tiny part of London, I tend to play the London map. If you want a real challenge then follow in the footsteps of over 40,000,000 previous attempts and ask to be dropped onto the “World” map (it can be VERY difficult but it is also a lot of fun (even if you end up getting dropped down in the middle of nowhere))
  • once you think you know where you were dropped down, put a pin down in the little map in the lower right-hand corner
  • you are scored on how far your claim of where you were dropped down is from where you were actually dropped down (my record on the “World” map for distance from the correct location is something like 8,000 km; generally speaking, if you do figure out where you were dropped down then it isn’t all that hard to get to within a handful of meters of the exactly correct location)
  • the GeoGuessr user interface can be a bit clunky at times. This is particularly true of the way that you drop the pin to indicate where you think you were dropped down at the start of the game. You might want to deliberately lose quickly a few times until you get the hang of exactly how you specify where you think you started the game.
  • if you end up enjoying the game, be advised that it is possible to spend a LOT of time playing GeoGuessr

That’s it. Off you go. I’ll be standing by to organize a search party should things not go according to plan.

The link takes you to the GeoGuessr map of the Netherlands. That’s not a very big place so, with a bit of luck and skill, you probably won’t get too lost.

Once you are on the map, just click on the GeoGuessr link on the top left corner if you’d rather play a different map.

“‘We’re moving to higher ground’: America’s era of climate mass migration is here”

An article that demonstrates that climate change is not some vague far off possibility. The reality of climate change is disturbingly simple: climate change is happening right now and is getting worse as time goes by.
