Choosing Between Code and Verbatim Markup In Org Mode

Its helped me to standardize my approach to marking up techie language. Keeping it simple the content is either programming stuff or everything else tech related. Sufficiently vauge you see: I write down examples to keep it straight in my head. Here you go:

How To Format USB Drive For A Printer Or Camera In macOS

Today I had to store a scanner’s scan onto a USB thumb drive. Unfortunately there weren’t any thumb drives sitting around that worked. Long story short I had to format the partition to be “device friendly.” What device do you ask? Cameras, printers, and scanners come to mind. What partition type are you wondering?

You might have easily guessed MS-DOS formatted. You might have easily forgotten like me it needs to be a MBR partition though. Doh!

WARNING: Unless you hold yourself responsible for the outcome don’t proceed.

Run diskutil list to see where your thumb drive is mounted.

Customize the command to specify the correct path now.

The command deletes everything on the drive and creates a single partition taking up the entire drive.

DOUBLE WARNING: IF YOU DO THIS WRONG YOU’LL LOSE ALL YOUR DATA!

The error would be specifying the wrong disk drive and poof your data is gone.

You seem to know what you are doing though.

Here is the command―you have to customize it for your thumb drive: 

sudo diskutil partitionDisk <<<thumb drive name>>> MBR MS-DOS "PRINTORSCAN" "100%"

Configuring A Simple-Modeline

Customizing your Mode-Line is one step forward on every Emacser’s right of passage. Whether you use the informative yet quiet built-in Mode-Line or the visually stunning doom-modeline: you are finding the right porridge for you. Here is my choice―a simple halfway between those two―simple-modeline.

Its so great that I copied and pasted the options here. Alternately run customize or open simple-modeline-segments.el and occur simple-modeline-segment on it. Yup, that great.

Read on for the variable info

You Gotta Try Using ~describe-symbol~

You gotta try out using describe-symbol because it is usually what you really want from describe-function and describe-variable.

The most useful part is that it instantly teaches you when there are both a variable and a function with the same name. Sometimes it is surprising and better to know right away. For example M-x describe-symbol RET emacs-version RET: 

emacs-version is an interactive compiled Lisp function in ‘version.el’.

(emacs-version &optional HERE)

Display the version of Emacs that is running in this session.
With a prefix argument, insert the Emacs version string at point
instead of displaying it.
If called from Lisp, by default return the version string; but
if the optional argument HERE is non-nil, insert the string at
point instead.

Don’t use this function in programs to choose actions according
to the system configuration; look at ‘system-configuration’ instead.

  Probably introduced at or before Emacs version 19.20.

―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――

emacs-version is a variable defined in ‘C source code’.

Its value is "28.1"

Version numbers of this version of Emacs.
This has the form: MAJOR.MINOR[.MICRO], where MAJOR/MINOR/MICRO are integers.
MICRO is only present in unreleased development versions,
and is not especially meaningful.  Prior to Emacs 26.1, an extra final
component .BUILD is present.  This is now stored separately in
‘emacs-build-number’.

  Probably introduced at or before Emacs version 19.20.

Org2Blog Release v1.1.13

Just released Org2Blog v1.1.13 with almost no user-facing changes but primarily maintenance and cleanup.

That said you might care about:

  • Create Entries without requiring an Internet connection to load Categories, Tags, and Pages. Previously it would error out preventing you from creating the Entry on your computer.
  • WordPress 6 broke View Entry. Fixed.
  • Although you were unlikely to have used org2blog-buffer-post-or-page-view or org2blog-subtree-post-or-page-view, you can’t anymore. See their function for details. Guessing you were unlikely since the break was never reported. Addendum: It was only broken for Page previews which are probably rarely used: makes sense.
  • Easier to check for compilation errors since long docstrings now get ignored.
