dbus (1.11.2)
D-Bus is a simple system for interprocess
communication and coordination.
The "and coordination" part is important; D-Bus

e2fsprogs (1.43.3)
e2fsprogs (sometimes called the e2fs programs) is a
set of utilities for maintaining the ext2, ext3 and ext4
file systems. Since those file systems are often the
default for Linux distributions, it is commonly
considered to be essential software

Fully modularized sound drivers.
SMP and thread-safe design (PLEASE READ THIS).
User space library (alsa-lib) to simplify application
programming and provide higher level functionality.
Support for the older Open Sound System (OSS) API,
providing binary compatibility for most OSS programs.

libjpeg-turbo (2.1.1)
libjpeg-turbo is a JPEG image codec that uses SIMD
instructions (MMX, SSE2, AVX2, Neon, AltiVec) to
accelerate baseline JPEG compression and
decompression on x86, x86-64, Arm, and PowerPC
systems, as well as progressive JPEG compression on
x86 and x86-64 systems. On such systems, libjpeg-
turbo is generally 2-6x as fast as libjpeg, all else being
equal. On other types of systems, libjpeg-turbo can
still outperform libjpeg by a significant amount, by
virtue of its highly-optimized Huffman coding
routines. In many cases, the performance of libjpeg-
turbo rivals that of proprietary high-speed JPEG
codecs.
