All these recent discussions of error handling and mishandling and parsing and NaNs in my timeline all circulating like NaTs on an #Itanium are reminiscent of the video player controls seen on a very much not-small website.

Oh, and as for NaNs and videos, and for the ~three of you that haven’t yet seen it, “A lightning talk by Gary Bernhardt from CodeMash 2012”, a very short and very funny video on this same topic:

Interesting floating-point summation tip [ https://twitter.com/raymondh/status/1301800636866940928 ]:

"Raymond Hettinger @raymondh

#Python floating point ninja tip: Use parentheses to regroup sums to minimize accumulated round-off error.

Instead of:
a + b + c + d + e + f + g + h

Write:
((a + b) + (c + d)) + ((e + f) + (g + h))

Note, the total work is unchanged."
