I find this shortcut extremely useful in Xcode: duplicate one or several lines without losing what you have on the clipboard.
UPDATE: it seems Xcode finally added this feature as of version 14: one can now select text and use the usual duplicate shortcut (Cmd-D)

A video artist approached me with the following problem: she wanted to play back a recorded performance art piece in "double-wide" format, i.e. two 16:9 videos next to each other.
The video was recorded with a 4k camera (3840x2160 resolution) and then edited and cropped to produce a 4k video file, in which only the "middle vertical slice" contains information (letterbox). After discussing several options, such as using a single 4k projector with a cropped image, we settled on using two FullHD projectors next to each other. Financial considerations played a significant role as well.
Playing back a 32:9 format video on 2 projectors was deemed as too fickle / difficult without using specialized hardware (video wall controllers) or software (e.g. Multi-View HD Pro 2. 2 older mac minis that were lying around seemd good candidates for the job.
The tasks at hand were roughly the following:
If your Meld looks like this (font kerning messed up)

Search for this snippet and replace SF Pro with e.g. Helvetica:

font-family: "SF Pro";
This gist contains my personal notes and gotchas identified while trying to create an .app out of a Python script and distribute it directly (outside App Store) via a .dmg. This subject has been the source of a lot of confusion and frustration throughout the years. Since altool was retired and replaced by notarytool things have improved in terms of documentation IMHO, but at the same time the 'screws are tightened' by Apple's Gatekeeper in incresingly short intervals. While I welcome added security as a whole, us developers need to jump through quite a few more hoops. It's almost as if they want to encourage you to distribute via the App Store...
All executable (incl. libaries) needs to be signed. pyinstaller does this with the codesign_identity specified (via command line option or in .spec file) and recursively to all dependencies bundled, including the Python executable.
The .dmg needs to be code-signed, too: `codesign --sign ${team_id} "${app_name}.dmg
