Hot Weather Supermarket Quench

We went to do slow shopping in Tesco two days in a row, followed by another Coop shopping trip.

Domestic Crimping

The little USB fan has failed, and it was a simple fix,  if I have a soldering gun,  that is.  So before giving up,  I tried to crimp.   It is fairly difficult to crimp without a crimper and within a small gap. 

It was a success!   Another thing saved from landfill. 

Combination Insole

I have a pair of memory foam insole,  it was too soft and will not stay in position when I slide my foot in.

I have a pair of leather insole,  it wasn't providing much cushioning.

A light bulb moment came,  I stacked them together.  Viola! 

Driving Recklessly

Youth is no excuse for driving recklessly,  regardless of vehicle. 

Debranding Freebies

With the access of my old sticker book, I have debranded some freebies from the Pride.  Another reason to keep a sticker book.

Set Theory Simple Proof

It has only just occurred to me, there is a simple set theory proof for a simple problem.

Typical Venn diagram

XX ≠ Ø, XY ≠ Ø 

XX ≠ XY

XX⊄XY, XY⊄XX

Importantly

XX ≠ XY', XY ≠ XX'

Then 

XX ∪ XY ≠ XX, XX ∪ XY ≠ XY

If 

XX x a = XY, and a ≠ Ø, what is a?

XY x b = XX, and b ≠ Ø, what is b?

As above a and b cannot be a NOT operator.

Instead of finding the vector a and b, it would be easier to draw a new set.

Asparagus Sand Hutton

We missed Sand Hutton asparagus last year due to their short season.  We finally made it back.  It is fresh and nice as always.  Their track is now extremely motorcycle unfriendly.
