LIBSVM is an integrated software for support vector classification, (C-SVC, nu-SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation (one-class SVM). It supports multi-class classification. Since version 2.8, it implements an SMO-type algorithm proposed in this paper: R.-E. Fan, P.-H. Chen, and C.-J. Lin. Working set selection using second order information for training SVM. Journal of Machine Learning Research 6, 1889-1918, 2005. You can also find a pseudo code there. Our goal is to help users from other fields to easily use SVM as a tool. LIBSVM provides a simple interface where users can easily link it with their own programs. Main features of LIBSVM include * Different SVM formulations * Efficient multi-class classification * Cross validation for model selection * Probability estimates * Weighted SVM for unbalanced data * Both C++ and Java sources * GUI demonstrating SVM classification and regression * Python, R (also Splus), MATLAB, Perl, Ruby, Weka, Common LISP and LabVIEW interfaces. C# .NET code is available. It's also included in some learning environments: YALE and PCP. * Automatic model selection which can generate contour of cross valiation accuracy.

The Data Encryption Standard (DES), also known as Data Encryption Algorithm (DEA) is a semi-strong encryption and decryption algorithm. The module is 100 % compatible to Crypt::DES but is implemented entirely in Perl. That means that you do not need a C compiler to build and install this extension. The module implements the Crypt::CBC interface. You are encouraged to read the documentation for Crypt::CBC if you intend to use this module for Cipher Block Chaining. The minimum (and maximum) key size is 8 bytes. Shorter keys will cause an exception, longer keys will get silently truncated. Data is encrypted and decrypted in blocks of 8 bytes. The module implements the Ultra-Fast-Crypt (UFC) algorithm as found for example in the GNU libc. On the Perl side a lot has been done in order to make the module as fast as possible (function inlining, use integer, ...). Note: For performance issues the source code for the module is first preprocessed by m4. That means that you need an m4 macro processor in order to hack on the sources. This is of no concern for you if you only want to use the module, the preprocessed output is always included in the distribution.

Crypt::RSA is a pure-perl, cleanroom implementation of the RSA public-key cryptosystem. It uses Math::Pari(3), a perl interface to the blazingly fast PARI library, for big integer arithmetic and number theoretic computations. Crypt::RSA provides arbitrary size key-pair generation, plaintext-aware encryption (OAEP) and digital signatures with appendix (PSS). For compatibility with SSLv3, RSAREF2, PGP and other applications that follow the PKCS #1 v1.5 standard, it also provides PKCS #1 v1.5 encryption and signatures. Crypt::RSA is structured as bundle of modules that encapsulate different parts of the RSA cryptosystem. The RSA algorithm is implemented in Crypt::RSA::Primitives(3). Encryption schemes, located under Crypt::RSA::ES, and signature schemes, located under Crypt::RSA::SS, use the RSA algorithm to build encryption/signature schemes that employ secure padding. (See the note on Security of Padding Schemes.) The key generation engine and other functions that work on both components of the key-pair are encapsulated in Crypt::RSA::Key(3). Crypt::RSA::Key::Public(3) & Crypt::RSA::Key::Private(3) provide mechanisms for storage & retrival of keys from disk, decoding & encoding of keys in certain formats, and secure representation of keys in memory. Finally, the Crypt::RSA module provides a convenient, DWIM wrapper around the rest of the modules in the bundle.

The main advantages to the Sun format utility are: - Working surface analyze that will detect defective blocks that are going to get bad. - Analyzing program that detects defective bearings in the disk (-randrw). - Will repair nearly any defective disk, that has no firmware bug or electric defect. - Allows to clear the grown defect list if a disk. - Disk geometry and label geometry are separated. - Allows cheating in the label geometry to deal with the problems with the limitation to 16 bit data types in the Sun disk label. - Large database of disks including firmware specials. - You need no desk calculator to generate a partition table. Shorthands for: - MBytes - cylinders/head/sectors - size partition to end on end of disk - partition following another partition - partition ending before another partition - shifting partition on the disk (allows growing part 0 and shrinking part 1) - Partition consistency checker with (ascii) graphical display. - Mode page interpreter allows to set easily all mode pages you will ever find in a manual, sformat needs not to know about them. NOTE: Sformat has its full functionality on SunOS/Solaris on sparc and Motorola systems, on all other systems sformat will create Sun disk labels with wrong byte-order, but formatting/analysis/ repair will work.

x2x allows the keyboard and mouse on one ("from") X display to be used to control another ("to") X display. Since x2x uses the XTEST extension, the "to" X display must support XTEST. In the default interface, x2x puts a window on the "from" display. This window is labeled with the name of the "to" display. Keystrokes typed into this window go to the window on the "to" display that has the input focus. Clicking on the x2x window causes the mouse on the "from" display to control the cursor on the "to" display. Perform- ing a subsequent multiple button click on the "to" display returns control to the "from" display. If the -east or -west options are specified on the command line, x2x starts up with a different interface. When the mouse moves to the (east or west) side of the default screen on the "from" display, the cursor slides over to the "to" display. When the mouse returns to to side of the "to" display that it entered, it slides back onto the "from" display. Unless the -nosel option is specified, x2x relays X selections from one display to the other.

Aewm is a modern, minimal window manager for X11. It is controlled entirely with the mouse, but contains no visible UI apart from window frames. It builds complex operations by chaining together primitives aewm does not try to do everything; there are plenty of better clients for defining hotkeys, menus, setting your background image, etc. Aewm makes it easy for you to keep the edges of the root window unobscured, so that you have essentially infinite space to click without having to aim (this principle is based on Fitts's Law). There is intentionally no panel or dock to get in the way. Aewm does not make decisions about where your windows should go. It can be used as an ordinary overlapping window manager, but is powerful enough to let you "tile" windows ad hoc if you prefer; maximizing space usage and removing overlaps are basic commands. You can also optionally take control of window mapping and change where windows will appear (including stacking and tiling) before they are actually shown. This port installs not only the window manager, but also the aemenu and aepanel applets. These provide a list of windows by title (vertically for aemenu, horizontally for aepanel) and a menu from which programs may be run.

http://www.linuxtv.org/vdrwiki/index.php/Remote-plugin This plugin extends the remote control capabilities of vdr. The following remote control devices are supported: (a) Linux input device driver ('/dev/input/eventX', X=0,1,2,...) (currently not supported on FreeBSD) (b) keyboard (tty driver): /dev/console, /dev/ttyX (c) TCP connection (telnet) (d) LIRC (e) some(?) FreeBSD uhid(4) devices (experimental support added by this port) To use, add something like this to vdr_flags: '-Premote -h /dev/uhid0', (re)start vdr, then the osd should ask you to configure the remote by pressing the buttons you want to assign. Note: If your remote is detected as a keyboard you'll have to tell ukbd(4) to ignore it first by doing (as root) something like: usbconfig add_dev_quirk_vplh 0x1241 0xe000 0 0xffff UQ_KBD_IGNORE (and possibly unplug it for a moment or reset it via usbconfig, 0x1241 there is the vendor id, 0xe000 the product id of the device, you can get yours by doing usbconfig -d 1.2 dump_device_desc and looking for idVendor and idProduct, -d 1.2 there corresponds to ugen1.2 listed by usbconfig w/o args.) You can check with: usbconfig show_ifdrv if the device is then listed as ugen...: uhid... you're good to go. 2nd note: If vdr cannot open your uhid device check it is not claimed by xorg: fstat |grep uhid If it is you may need an xorg.conf(5) with manually defined InputDevice sections for mouse and keyboard and Option "AutoAddDevices" "False" in the ServerFlags section. And if for some reason you want to reassign the buttons on the remote you can stop vdr and do: touch /usr/local/etc/vdr/channels.conf and/or remove uhid entries from /usr/local/etc/vdr/remote.conf . When you then start vdr again it should ask to configure the remote again.

[ excerpt from developer's web site ] JZlib is a re-implementation of zlib in pure Java. The first and final aim for hacking this stuff is to add the packet compression support to pure Java SSH systems. - Why JZlib? Java Platform API provides packages 'java.util.zip.*' for accessing to zlib, but that support is very limited if you need to use the essence of zlib. For example, we needed to full access to zlib to add the packet compression support to pure Java SSH system, but they are useless for our requirements. The Internet draft SSH Transport Layer Protocol says in the section '4.2 Compression' as follows,
