Data Shovel Pinnacle Performance Utilities is a collection of utilities for large input/output tasks. bare takes line feed-separated file names on standard input and concatenates the file contents on standard output. baresha512 takes line feed-separated file names on standard input and provides the SHA512 message digest for the concatenated file content on standard output. Both can optionally open and read files with O_DIRECT, bypassing the kernel's block cache. cock provides a digital petcock. It relives I/O pressure on the kernel by rate limiting data throughput. It can auto-throttle to mitigate lag spikes, or use a specified megabytes-per-second rate limit.
losetup-utils are three bash scripts that attempt to make the use of losetup a bit easier and faster. losetup can be fast, easy, and practical if you need to transport sensitive information over the Internet or in CD's, DVD's, or a pendrive. Also, if you want to store private data on your hard disk or in the cloud, an encrypted volume can be a convenient choice. The types of encryption can be any installed on the system.
Cock provides a digital version of a petcock. A petcock is a valve or faucet used to drain pressure, as from a boiler. Cock drains I/O pressure from the kernel. Without parameters, the output rate automatically adjusts; cock defers output when necessary in order to mitigate I/O spikes. Otherwise, a numeric parameter specifies megabytes per second.
mhvtl is a Linux-based virtual tape library. Supported tape emulations are IBM and HP LTO1, 2, 3, 4, and 5, Sony AIT4, STK T10000A, B, and C, and STK 9x40. It supports WORM, data, and cleaning media. Most applications work using STK L180/L700 library emulation. It has been successfully used with NetBackup, BackupExec, NetWorker, TSM, Oracle Secure Backup, and many other programs.
GTK+ Recent Files Scrubber is a compact, lightweight Python script which uses GTK's RecentManager to watch for updates to all globally-available "Recently Used" lists (the ones which appear in Open dialogs and the like) and filter out anything in the folders you blacklist. Blacklist entries are hashed to make reading the blacklist not worth the effort.
