clone is a file tree cloning tool which runs 3 threads - a scheduler (main), a reader, and a writer thread. Reading and writing occurs in parallel. While this is most beneficial for copying data from one physical disk to another, clone is also very well suited for cloning a file tree to any place on the same disk. Cloning includes the whole directory hierarchy, i.e. sub-directories, files, hard links, symbolic links, attributes (modes, flags, times), extended attributes and access control lists. clone is useful for cloning (thus backing-up) live file systems, and it can also be used in incremental and synchronization mode. clone works on FreeBSD and Mac OS X. clone is very fast, for example, cloning a whole UFS2 file hierarchy on FreeBSD 9.1 of in total 2.3 TBytes of data from one hard disk to another took 7.5 h, so the average transfer rate for all kind of files (very small up to very big ones) was about 89 MByte/s.

powerman is free Unix/Linux software that controls (remotely and in parallel) switched power distribution units. It was designed for remote power control of Linux systems in a data center or cluster environment, but has been used in other environments such as embedded management appliances, home automation, and high availability service management. powerman can be extended to support new devices using an expect-like scripting language. It communicates with devices natively using telnet, raw socket, and serial protocols. It also can drive virtual power control devices via a coprocess interface. The coprocess mechanism has been used to extend powerman to communicate with devices using other protocols such as SNMP, IPMI, Insteon, X-10, and VXI-11. powerman can control equipment connected using any combination of the above methods and provide unified naming for the equipment and parallel execution of control actions.

U-Boot loader for Banana Pi. To install this bootloader, follow the instructions in http://linux-sunxi.org/Bootable_SD_card#Bootloader This version is patched so that: * ELF and API features are enabled. * The default environment is trimmed to just what's needed to boot. * The saveenv command writes to the file u-boot.env on the FAT partition. * The DTB file name is chosen based on the board model and passed to ubldr using the fdtfile env variable. ubldr loads the DTB from /boot/dtb/ on the FreeBSD partition. * By default, it loads ELF ubldr from file ubldr on the FAT partition to address 0x42000000, and launches it.

U-Boot loader for PandaBoard. To install this bootloader, copy the files MLO and u-boot.img to the FAT partition on an SD card. Normally this is partition 1, but different partitions can be set with U-Boot environment variables. This version is patched so that: * ELF and API features are enabled. * The default environment is trimmed to just what's needed to boot. * The saveenv command writes to the file uboot.env on the FAT partition. * The DTB file name is passed to ubldr using the fdtfile env variable. It defaults to omap4-panda.dtb unless you override it. ubldr loads the DTB from /boot/dtb/ on the FreeBSD partition. (Not tested) * By default, it loads ELF ubldr from file ubldr on the FAT partition to address 0x88000000, and launches it.

NLTK is a leading platform for building Python programs to work with human language data. It provides easy-to-use interfaces to over 50 corpora and lexical resources such as WordNet, along with a suite of text processing libraries for classification, tokenization, stemming, tagging, parsing, and semantic reasoning, and an active discussion forum. Thanks to a hands-on guide introducing programming fundamentals alongside topics in computational linguistics, NLTK is suitable for linguists, engineers, students, educators, researchers, and industry users alike. NLTK is available for Windows, Mac OS X, and Linux. Best of all, NLTK is a free, open source, community-driven project. NLTK has been called "a wonderful tool for teaching, and working in, computational linguistics using Python" and "an amazing library to play with natural language".
