Gisdnbutton is a GTK-based ISDN monitor inspired by the old isdnbutton program written in 1996 by M. Gutschke. Gisdnbutton monitors the state of an ISDN connection (down, pending, incoming or outgoing) and displays it as a traffic light. The state of the connection may be changed by clicking the traffic light icon. Unlike isdnbutton, Gisdnbutton monitors both /proc/net/route and /dev/isdninfo, allowing for more detailed information about the different states. Gisdnbutton also distinguishes between incoming (blue) and outgoing (green) connections, can be started from the DisplayManager*setup: script (for gdm, kdm or xdm) instead of running as suid root, and can monitor a subrange of ippp devices, hence allowing the use of more than one process with each monitoring its own uplink.
Tsprof and pmprof measure the running of an existing binary executable program on Linux/x86. They report counts of entries and events using process-virtual hardware counters of clock cycles and CPU events. The output includes text, graphics, and colorful interactive graphics. Tsprof and pmprof can be used with a wide range of programs, including shared libraries, dynamic modules, pthreads, and SMP.
cmictl sets some internal parameters of CMI 8338/8738-based sound cards. It allows you to utilize the S/PDIF out of your card. cmictl can control S/PDIF-in, S/PDIF-out, S/PDIF-loop, S/PDIF-monitor (SPDIF-in to Analog-out), S/PDIF-out voltage (5V / 0.5V), and S/PDIF frequency (48kHz / 44kHz). Some parameters are only available on CMI8738-based cards.
