Convert PCF and BDF files to bitmap only OpenType (.otb) using fontforge
Convert PCF and BDF files to bitmap only OpenType (.otb) using fontforge
If you have a new enough fontforge, the python version of this script can
optionally read filenames from standard input, generating multiple .otb
font files as it finds new families. It also handles gzipped PCF and BDF
files.

PulseAudio as a Server

Multiplexing Access to Audio Hardware via a Single PulseAudio Server

The goal of this setup is to create a single pulseaudio service which has sole access to the audio hardware while providing a server for many clients to use. This is not using the system wide mode as it doesn’t run as root, nor does it use the --system flag.

One disadvantage of this arrangement is that the commands pacmd and pactl will no longer work when run as your user. Both rely on the user dbus session

  • A "shall" or "shall not" requirement that appears outside of a constraint is violated (clause 4).
  • A nonempty source file does not end in a new-line character which is not immediately preceded by a backslash character or ends in a partial preprocessing token or comment (5.1.1.2).
  • Token concatenation produces a character sequence matching the syntax of a universal character name (5.1.1.2).
  • A program in a hosted environment does not define a function named main using one of the specified forms (5.1.2.2.1).
  • A character not in the basic source character set is encountered in a source file, except in an identifier, a character constant, a string literal, a header name, a comment, or a preprocessing token that is never converted to a token (5.2.1).
  • An identifier, comment, string literal, character constant, or header name contains an invalid multibyte character or does not
