15-page article belonging to my "Boldly Going" series, this is the original version for the HP-71B of my article "HP Article VA042a - Boldly Going - Outsmarting PROOT (42S)".

Though this article appears at first sight quite similar to the version for the HP-42S published in Update #24, it was actually written earlier and includes additional sections discussing the internal workings of PROOT and their differences, as well as more examples specific to the 12-digit precision available in the HP-71B, which aren't featured in the HP-42S version. Also, it can be very useful for HP-42S users to better understand the RPN version innards, as the BASIC code is much clearer and the algorithm is exactly the same.

The article includes a small 11-line BASIC subprogram PZER (plus an optional driver) for the HP-71B and emulators (Emu71/DOS, Emu71/Win, go71b, etc.) dealing with a glaring limitation of the HP-71B Math ROM’s keyword PROOT, the polynomial root finder which finds at once all real/complex roots of an Nth-degree polynomial but only works for polynomials having real coefficients. On the other hand, PZER works efficiently and accurately for polynomials whose coefficients are real and/or complex, and can work globally (no user inputs or initial guesses required whatsoever, just the coefficients) while also providing the user with extra control if desired. It can be called from your own programs or manually from the command line.

http://curious.galthub.com/blog/typewriters/ might be useful to get math rendering working on my blog.
http://curious.galthub.com/blog/bashrc/ uses /etc/hostname to determine the name of the host, maybe I should use that on Android?

Found the blog via a link to https://optimizedbyotto.com/post/reasons-to-stop-using-mysql/ on the Devuan list https://lists.dyne.org/lurker/message/20260121.090950.6486b344.en.html
Other articles such as https://optimizedbyotto.com/post/writing-tips-for-software-professionals/, https://optimizedbyotto.com/post/linux-containers-docker/, https://optimizedbyotto.com/post/restist-the-urge-of-quick-solutions/ sound interesting.
The article https://optimizedbyotto.com/post/pulsar-best-text-file-and-code-editor/ has some errors: " neither of them [vim, Emacs] has a graphical user interface, and they are completely incapable of doing things like showing images or, for example, a Markdown preview". Emacs can show images and probably can be taught to show a Markdown preview. The statement about modes (for Emacs) is misleading as well, Larry Tesler's statement 'Tesler was very keen on "modeless" software, where a user would not have to, for example, use a keyboard to switch to a command mode before switching back to edit text.' on https://www.theregister.com/2020/02/19/larry_tesler/ describes vi[m]'s modes, but Emacs modes are different, since you do not switch between command and text entry modes.
