Wise Owl's monthly (ish) news tweet | Issue 43 - March 2021
The items included in this newsletter are listed below. Our newsletter go out about once a month - if you'd like to subscribe, just let us know!
The many reviews on our website are all very well, but (for example) someone else's view of a classroom SQL course may not help you guess what your own online Power BI course will be like. To help you discriminate, we've provided the ability to filter our reviews by course type, software and industry sector.
A rare chance to see what a Wise Owl online course looks like from the trainer's point of view, showing one screen for people's faces, a second screen to check that everyone is keeping up and a third screen allowing us to share what we're doing.
For some time now we (well, I anyway) have been advising delegates on our Power BI courses to delete columns not used in reports or relationships (and particularly ones with lots of unique values). Sadly, deleting a table's primary key field can give misleading results if this leads to duplicate records, as this blog explains.
This month you're invited to solve a codeword (with a little tweak at the end). As always the sender of the first correct solution drawn out of our electronic sorting hat will win a 50-pound Amazon voucher. Congratulations to Corin Lee of Macquarie Energy Leasing for winning last month's puzzle (you can find the details and answer here).
If you're looking for a present for the geek in your life (yourself, perhaps), consider giving this collapsible 7-screen laptop a whirl. At about 12 kilos or 26 pounds it's not that portable, but you can have great fun folding it up Transformers-style.
