Play Warcraft III via Wine on Linux with working videos/cutscenes!

Prerequisites: original Warcraft III CDs

  1. Create ISO images from your CDs using K3B. Important: check "clone copy" checkbox, otherwise copy protection will not work.

  2. Mount the created ISO files using gCDEmu. In gCDEmu settings, check "DPM Emulation", "Rate Emulation", "Bad Sector Emulation". (Note: the original CDs are multisession discs - when mounting with the Gnome integrated ISO mounter we get the OSX session, but we need the Windows installer)

  3. Install newest Wine version as described in https://gitlab.winehq.org/wine/wine/-/wikis/Download

  4. Install necessary video codecs: apt install gstreamer1.0-plugins-good:i386

Configure Datalogic QR/barcode scanner to send line break (\n) as ENTER
Datalogic scanners are normally sending CTRL+J when reading a line feed (LF) character and ENTER when reading carriage return (CR).
That's not cool if you use the scanner with Linux or Android since QR codes mostly use Unix line endings (LF only) when they contain line breaks.
You can work around by using the character replacement feature of these scanners.
Use the Datalogic online tool to create a config code: https://aladdin.datalogic.com/
1. Select your scanner
2. Go to "Data Format" -> "Character Replacement"
3. Enter "0A0D" for "Character Conversion" to tell the scanner to replace LF (hex "0A") with CR (hex "0D")

Solution for Firefox showing context menus and password popups at the wrong position
In some constellations, Firefox shows context menus at a complete different position on the screen, especially when the window was dragged to the left or right screen side so that it snaps in and fills 50% of the screen (known as "Aero Snap" on Windows).
Fix:
1. Right-click on the title bar -> "Customize Toolbar..."
2. On the bottom, uncheck the checkbox "Title Bar"
That's it! Without the title bar, all menus and popups are shown on the correct position!

Simple WordPress plugin to set the "envelope sender" correctly, so that e.g. Gmail accepts them. Just create a folder "wp-content/plugins/fix-mail-sender" and put this file there. Don't forget to activate the plugin and enjoy. Note: if you are on Hetzner, you need to create a mailbox "[email protected]" too to make it work. Don't ask why.
