Today, I learned that:

Besides dedicated software applications, e.g. translation software, without any doubt, it is the general applications word processing and spreadsheet calculations I use most, as I guess is the case for most people.

Of those, it is especially the spreadsheet that I tend to use for almost any task. Back in the 1980s, unfortunately I did not use the very first spreadsheet, Visicalc, which was introduced for the Apple II in 1979. More about that in reference # 1 below. But soon after that, I already started to use various of its successors, which during the following decades have included such softwares as Lotus 1-2-3, Multiplan, Quattro, Excel and Numbers.

Now there is even celebrated a Spreadsheet Day, on October 17 every year, in remembrance of the date of introduction of Visicalc. And on that day this year, I had the pleasure of receiving a newsletter from a person who knows a great deal about spreadsheets. Her name is Mynda Treacy, and in that newsletter she presented a comprehensive article about how to work with dates and times in Excel, which currently is the most commonly used spreadsheet application worldwide. If you think that it is difficult to use them in Excel, Mynda will explain it to you in an easy fashion, complete with all the formulas you need. See reference # 2, where you can download the article and accompanying spreadsheet file, as well as sign up for her newsletter.

And now back to another favourite topic of mine, robots. Examples of that can be seen in my posts from 2016-03-12 and 2017-03-12. In both of them were presented robots from the American company Boston Dynamics, named Atlas and Handle. Now, its new owner, the Japanese company Softbank, reveals how Atlas has developed since we last saw it. How about the following backflip? More about Atlas, including a video, can be found in reference # 3 below.

That’s what I learned in school !
