This is a log-log plot of the size and mass of various types of thing in the universe.

Orders of magnitude
I wanted to get some intuition for what made a bigger difference: adding an extra item to a set, or having an extra order of magnitude of items in a set. So I created this spreadsheet and discovered that an extra order of magnitude smashes an extra item in the set.
In the spreadsheet the parameters are ‘x’, which is the size of the base set (called Set A), and ‘i’, which is the number of extra items to add into the second set (called Set B).
If you make x = 10 and i = 90 you break even, Set A and Set B grow at the same rate.
If you make x = 10 and i = 1 it’s no contest, Set A gets much bigger much faster.
Wire Gauge
So according to Wire Gauge Sizes the gauge size does not included the size of the insulation. Good to know.
Understanding SMD size code
Today I discovered Understanding SMD size code which does a good job of explaining imperial vs metric SMD/SMT size codes. Note “SMT” means Surface Mount Technology and “SMD” means Surface Mount Device.
Big universe
Stumbled upon this homage to the old powers of ten video from the 70s: Our Universe is SO big, it’s mindblowing! 🤯 BBC.
DC Power
So the standard/typical size of the most common DC power plug/socket is 5.5 x 2.1 mm. There are a bunch of other sizes too.
Font size is useless; let’s fix it
This on r/programming today: Font size is useless; let’s fix it. Interesting article, but I didn’t read it closely.
VSCode explorer tree indent size
So I was poking about in my VSCode settings, File -> Preferences -> Settings. And I found the Workbench > Tree: Indent options which controls the tree indentation in pixels. The default settings was 8 pixels, which is too small for my liking, so I cranked it up a notch to 37 pixels! Yay woo!
The Surprising Impact of Medium-Size Texts on PostgreSQL Performance
Today I read The Surprising Impact of Medium-Size Texts on PostgreSQL Performance which popped up on reddit.
The Universe and Stuff
The age of the universe is 13.798 billion years.
The size of the universe is unknown, it may be infinite.
A galaxy is a massive gravitationally bound system. There are probably more than 170 billion galaxies in the observable universe.
