Vale Frank Bowman


Frank BowmanFrank Bowman the leader of our Penrith SIG passed way suddenly August 2016.

Frank ran the Penrith group from the St Clair High School Computer rooms for many years until the school was lost in a fire at which stage Warren, one of the group members offered his home as a venue. The group has continued to meet there ever since. At our last meeting Frank was unwell but still generated a great discussion. He had finally installed Windows 10 and we discussed the successes and failures in that venture. Last month he won the Trend Micro Maximum Security prize and spoke about its installation.

A great teacher and always available for great tips and advice we will miss him greatly.






Here is Frank's last report for the Penrith Group


Our August meeting took place on a sunny winter's day. The first session continued looking at and testing some useful formulas in spreadsheets. We concentrated on standard deviations, which are mainly used by statisticians and educators. Standard deviations are measures of dispersions in a series of numbers, or how spread out the numbers are. As an example, we looked at average monthly temperatures at Alice Springs, compared to average monthly temperatures at Sydney. Alice Springs's temperatures are more spread out and so have a larger standard deviation than Sydney's temperatures. The formula used in calculating a standard deviation is tedious but not difficult, As expected, the spreadsheet program worked out each exercise in a flash. We found we were able to use the autofill function with the standard deviation formula with the 90 random numbers we used last month for various spreadsheet exercises. This is a terrific time saver.

Instead of using Excel, we used Libre Office, which handled all exercises impeccably. This was the case also in comparing Libre Office with Microsoft Word. While most of us would prefer to use Microsoft Office, the industry standard, the free Libre Office is most appealing. We used a Word file that had a large, customised table inserted in it.  

We were able to take a careful look at Audacity before the tea lady came. I've used the program for about 15 years and have found it a fantastic piece of software, with more features for audio editing than most of us would ever need. We edited another doctor joke (a robot lie detector). 

The last item we discussed came from notes on the Raspberry Pi version 3 mini computer. Each successive version has added more features, such as additional RAM and a faster processor. For a little over $100, we can buy the latest version in a case, with RAM and its own version of Linux, with Bluetooth and Wi-Fi. There are 4 USB ports, an ethernet port, a HDMI port and an audio/video port. Pi 3 has a quad core processor. It may need a little setting up, like ALL computers, but apparently now can operate as a credible, basic computer.

Happy days, Frank
