How to create a bootable Windows 7, 8, 10, 11 installer USB on macOS

Run in Terminal:

brew install wimlib - run, if wimlib is not installed yet (required for splitting large files)
To identify target USB device, run: diskutil list
Format USB drive: diskutil eraseDisk MS-DOS "$WIN_USB_NAME" MBR /dev/$DISK where $WIN_USB_NAME is a new volume name (e.g. WIN) and $DISK is a target disk identificator (e.g. disk5). Alternatively, you can try GTP partititon style instead of MBR (recommended for UEFI = newer Windows distributions)
To mount Windows installer image, run: hdiutil mount ~/Desktop/$WIN_INSTALLER_IMAGE.iso where $WIN_INSTALLER_IMAGE is installer image name.
Copy all files to the USB drive, beside the "install" file (if it's over 4GB size): rsync -vha --exclude=sources/install.$EXT /Volumes/$WIN_INSTALLER_NAME/ /Volumes/$WIN_USB_NAME where $EXT is wim or esd, $WIN_INSTALLER_NAME is the mounted Windows installer volume name and $WIN_USB_NAME is target disk name.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Testing notes

Uncle Bob: Test First

Source: http://blog.8thlight.com/uncle-bob/2013/09/23/Test-first.html

tests are specs for the system and are more important than the system itself
(Tests should be) short, well factored, and well named. They ought to read like specifications; because they are specifications
(Goal:) trust your test suite to the extent that, if it passes, you know you

Find Free Port with PHP

This is a quick way to find a random free port on a system using PHP:

$port = find_free_port();

Benchmarked locally, where finding a port always took around 0.15ms.
