Hmmm. Any advice for doing big dataset lookups / array work on excel?

The downside of using excel to build dashboards with very large data sets....
Gone for formulas rather than power query for lookups etc as does process faster. However still glacial compared to DAX and PowerBI.
Wishing for Google Looker! (School can't afford a power BI license)

This morning's emergency lesson prep has consisted of cobbling together ancient laptops and installing @raspberrypi.com OS to have some working hardware on the ward this morning.
Have to say Raspberry Pi OS is just about perfect for this 👍
Now if only one would hold charge....

"There's no such thing as bad weather, just bad kit" - managed to have both on #Dartmoor this morning but the boys didn't mind!
It's evidently waterproof trousers season.

Rather lovely evening to take photos of my bike on #Dartmoor and ride a bit.
Really wanted to ride the track beneath Shell Top for a while. Top bit ok, first bit of descent not really doable on the gravel bike but the section through Newark Waste was brilliant 👍

A very good day at #OperationMarketHarborough - youngest got to watch one of his heroes ( #MrHewes ) and loved the large machinery, eldest loved the history and machinery, and taking photos with his uncle.
Both boys now exceptionally tired and hungry.

And we have cooling!
It appears my Teltonika router I use for timing has breathed its last, it's very secondhand but being shut in a black box on sunny days probably doesn't help.
New router on the way but a small fan to draw air through the case now added. Exterior baffle a work in progress.
