Orac is a GUI tool for Database Administrators written in Perl, Tk, and DBI. It organizes many useful DBA scripts into a nice graphical interface, for collecting statistics on your database, or diagnosing problems. It currently supports Oracle, Sybase, and Informix. Richard Sutherland's DDL::Oracle Perl module has been integrated with the current version for the Oracle side of things, greatly improving the Oracle developer options on the program.
Paralogger is a script to "tail" the system logs in borderless transparent Eterm(s). Its purpose is to make setting up a "root tail" an easy set and forget. Paralogger makes the placement of the terminals (geometry) more friendly for the user by detecting the screen resolution and calculating the geometry of the terminals automatically. It can also load or save a configuration file.
Sfront compiles MPEG 4 Structured Audio (MP4-SA) programs into efficient C programs that generate audio when executed. MP4-SA is a standard for normative algorithmic sound, which combines an audio signal processing language (SAOL) with score languages (MIDI and SASL). Under Mac OS X and Linux, sfront supports real-time, low-latency audio input/output and MIDI input. Under Mac OS X, sfront supports the creation of AudioUnit plug-ins. The documentation includes a book about SAOL programming.
Webfs (a.k.a. webfsd) is a simple HTTP server for purely static content. You can use it to serve the content of an FTP server via HTTP, for example. It can also be used to quickly export some files by starting an httpd server in a few seconds, without editing config files first. It knows how to use sendfile() on linux and FreeBSD. There is also sendfile emulation code which uses read()+write() and a userland bounce buffer; this allows one to compile and use webfs on systems without sendfile(). The stripped binary is less then 32Kb, making it great for floppy distros, recycled hardware, embedded systems (cramfs/romfs/flash disk) and other resource-limited environments.
The Parallel Virtual File System is a user-space parallel file system for use on clusters of PCs (and Beowulfs in particular). It provides transparent file striping across multiple machines and includes a loadable kernel module for use with existing binaries. TCP/IP is used for data transmission, and file data is stored on existing file systems on each machine.
noflushd is a simple daemon that monitors disk activity, spins down disks whose idle time exceeds a certain timeout, and stops writes to them in order to keep them spun down as long as possible. It's mainly used on laptops to save power, but can also be useful to desktop users with noisy hard disks. noflushd requires a kernel thread named kupdate which is present in Linux kernel version 2.2.11 and later. For earlier kernels, bdflush version 1.6 provides equal functionality.
