… and other palindromes
I linked to Dan & Dan’s Daily Mail Song 10 years ago, but I only just discovered another of their works that is even more appropriate for this forum:
To find out why it is appropriate, view it on YouTube, and click on “more”.
The Dan & naD video prompted me to revisit some other palindromes, including:
Douglas Hofstadter’s Crab Canon
MC Escher’s Crab Canon:
JS Bach’s Crab Canon:
and finally Weird Al Yankovic’s “Bob”
The RC Design Functions 9.0 spreadsheet is now available for free download from:
The main change is update of shear capacity calculations for the latest versions of the Australian codes; AS 3600 and AS 5100.
Shear data input now includes:
Shear results can be returned from the UMom function with the output index (offs1) 11 or 12, with 11 returning a summary of shear capacities and 12 a detailed listing of data from the shear caalculation:
If the “Use Simplified” option is set to “False” (default) the bending capacities are also re-calculated with the available longitudinal reinforcement area reduced by the area required for the input shear and torsion:
The UMom function calls a new function, ASShear, for the shear capacity calculation. This function may also be called directly as a user defined function, which returns the full output listing as a single column:
Note that the provisions of the current versions of AS 3600 and AS 5100.5 are sometimes inconsistent, and a further revision of AS 5100.5 is expected later this year. Further details of the new requirements for shear and torsion calculations will be published in future posts.
The function returns my interpretation of the current requirements of each code. As always, the results must be independently checked before using for any real appication.
Dreamers’ Circus is a Danish folk/indie band who have been around since 2009, but I have only just discovered them.
Here is an example of their work, featuring the clog fiddle:
“About the clog-fiddle: You take an old clog shoe, cut away the upper part, and put some violin-stuff on top of it, like strings and most notably a violin neck. Popularized in the first decade of the last century by the famous Swedish string trio, Källnatrion, this instrument used to be the poor man’s alternative to the expensive and hard-to-get violin. Now Ale and a handful of other extreme enthusiasts are working hard to bring this noble instrument out to the world to share the masterworks of the clog-fiddle-luthiers från Skåne, Sweden. Ale was titled world champion of the clog fiddle at the 2017 championship in Skåne.”
Microsoft announced earlier this year that they would be automatically blocking macros in downloaded Office files (as a security measure), then recently they said they wouldn’t, then yesterday they said they would, but not right now.
For more details, plus numerous comments see:
Microsoft: Roll back of VBA macro block in Office is only temporary
For more details about what can be done about it, including details of how to add security certificates without spending a fortune see:

How this will affect files downloaded from here, I am not sure, but if you have trouble using the VBA code in any of the download files, please let me know.
As for my opinion on how Microsoft have handled the whole thing, I’m appalled:
