Free flavor of love casting software for linux

The Linux SMP kernel uses spinlocks to protect data structures from concurrent, potentially conflicting accesses. Linux Kernel Spinlock Metering is a kernel patch that allows you to build an i386, ia64, Alpha, Sparc64, or mips64 kernel that can perform simple "metering" (record-keeping) of spinlock usage. Also available is source for an associated new command, lockstat, that is used to instruct the kernel to turn this lock metering on or off, and to retrieve the metering data from the kernel and display it in a human-readable format.

Data displayed includes the number of lock attempts, per-spinlock per-caller, the number of those attempts that were immediately successful vs. those that required the attempting locker to wait for the current lock-holder to release; the mean and max hold-time, and the mean, max, and cumulative wait-time. Whenever possible, the locking caller and the spinlocks are identified by their symbolic names, not by their virtual addresses.

Various patch sets are available. Version 1.1.4 patches the 2.2.14 kernel and reflects a relatively old flavor of Lockmeter. Version 1.4.11 patches the 2.4.16, 2.4.17, 2.5.3, and 2.5.5 kernels, and the previous release v1.4.9 patches various other releases of the 2.4.x kernel. This version 1.4 supports i386, alpha, ia64, mips64, and sparc64. The most recent version 1.5 is available as a patch against the 2.4.18 and various 2.5.x kernels, and it additionally supports mips (32-bit mips). Each is approximately 22 KB in gziped size. (Patches against a few older kernel versions are also available in the old subdirectory.) After applying the appropriate patch, make oldconfig presents a new Kernel lock metering option in the Kernel hacking subsection -- although only if CONFIG_SMP (Symmetric multi-processing support) has been enabled. The spinlock metering code is compiled into the kernel only when this new option is turned on.

Compiling the spinlock metering code into the kernel does not materially affect the kernel size because the additional code is roughly compensated for by the shrinking effect of the normally in-line locking routines now becoming procedure calls. A metering-capable kernel (i.e., with the patch applied, but data collection turned off) is negligibly slower than a non-metering-capable kernel, though a metering-capable kernel does slow when the metering data collection is turned on using the lockstat command (typically 8% for a systime==25% workload). Care has been taken to minimize performance degradation, and further improvements are in progress.

The lockstat command must also be downloaded, compiled, and installed. lockstat is a privileged command that requires root access. It reads and writes to the node /proc/lockmeter to control the kernels metering as follows:

lockstat on enables the kernels metering data collection,
lockstat options displays the collected data, and
lockstat off disables the metering data collection.

Run lockstat with no arguments to see a verbose description of the command arguments and options.

When metering is enabled, count and time data is collected in malloced arrays that are private to each CPU, thereby avoiding costly cacheblock coherency operations that would otherwise be required if all CPUs updated the same count and time fields. The lockstat command accumulates and sorts the per-cpu data at display time.

Lockmetering attempts to provide both "cause" and "effect" information about spinlock usage. The "hold time" metering exposes which spinlocks are being held and for how long, identified by where they are held inside the kernel. The "wait-time" metering exposes the effects of these hold-times when multiple CPUs concurrently contend for the same lock.

Ogrian Carpet project is a 3D fantasy action/strategy game.
Ogrian Carpet is an outdoor first person shooter game with real time strategy elements, inspired by the game Magic Carpet.
It uses Ogre3D as the renderer and allows you to fly around an island casting spells, summoning monsters, collecting mana, and building castles.
The object of the game is to build a castle, collect mana, and destroy your enemies. To build a castle, select a location, look at the ground, and cast the build spell. Note, you cannot build castles very close to water or other castles.
Your castle starts out small, with only one turret. As more mana is added to your castle, it will gain more turrets. Each turret adds another crane to your castles defense and another spell to your arsenal.
Basically, the game consists of fighting for control of mana. Whenever you encounter another wizard, shoot them with fireballs. If you hit them enough, they will "die" and be sent back to their castle. You are then free to claim all the mana in the area for yourself.
Once all the mana has been claimed, attack your enemys castle to get mana out of it so you can claim it for yourself. Once you enemys castle is out of mana, you can eliminate it by killing its heart. When all of your opponents have been banished, youve won.
Enhancements:
- AI bot player for skirmish
- things can now be loaded from an image, rather then randomly
- option for old randomized maps
- trees can now always bee seen
- made castle mana drops aggregate more
- loosened the restrictions on summoning
- made the config menu better
- added victory conditions to skirmish: kill all enemy towers/castles
- made ticks and gnomes stay in the formation you put them in
- made monsters and towers drop less then their cost when they have no wizard
- made mana float higher
- made towers cheaper (50)
- made sentinels drop much less (3)
- changed speed behavior on lava maps
- added victory music
- new music

Sub Ether is a system that includes software to network computers together over the Internet so that applications can share resources.

Sub Ether is basically a grid computer over the Internet using volunteers spare CPU and disk resources.

An example application written for Sub Ether is sedistcc. It allows you to use distcc to use compilers on machines running elsewhere on the Sub Ether network.

Quick Install for Unix:

If you untar/zip SubEtherInstallRelease-*.tgz youll get a few directories of source,
and some scripts:

1) buildse.sh builds the source code on some number of unix machines
2) installse.sh does a simple copying/updating of files to /usr/local/subether
3) setupsetorunandstart.sh will update /etc/inittab and make a file in /etc/xinetd.d

If you are running a flavor of unix that the script does not recognize it wont update
anything. You have to be root for this to work, and you have to have the balls to run it.

Run buildse.sh

Ive tested it on some number of redhats and freebsd and AIX. I also have a build
for windows, but it doesnt include the compiler program, so it would be good for socket bouncing only at the moment, until I finish some more applications (like sefile)

If all goes well, youll get a clean build. Dont worry about seeing it the build was
clean, the install script will complain if somethings missing.

If you can log in as some user that has access to /usr/local oot and dont have a
problem with putting stuff in /usr/local/subether, then you can run installse.sh as is.

Run installse.sh

*** OR *** if you want to install it into another directory (say because you dont
have root on the machine) you can specify where to put it by passing the directory as
a parameter:

Run installse.sh /path/to/existing/dir/subether

The /path/to/existing/dir has to exist, the script will create subether. You dont
have to call it that, but why wouldnt you.

Then, if youre all excited that things are going really well in your life, and
youre feeling really ballsy, run setupsetorunandstart.sh

Note, as of release 2, this doesnt exist yet, but it will.

Run setupsetorunandstart.sh

This is the finiky bit so you might want to do this by hand.

You have to be root for this to work anyway.

It will check to see if you have distcc set up on the machine, and if so,
create a file /etc/xinetd.d/distcc.

It will also add a few lines to the bottom of your /etc/inittab, and back up
the old one. And also add a line to /etc/services for distcc

Then it will kick xinetd, and telinit q. And if all goes well, youll be a
happy member of the Sub Ether network already sharing your spare cpu for use by other people using subether and distcc.

If you want to use distcc to do your compiles with the help of the Sub Ether
networked computers, you have a few more steps of setup that are covered in the
HOWTO-install_sedistccd file.

stic bundles a few Linux tools which are intended to support the task of collecting an unreasonable amount of pictures (preferrably in JPEG format).
similar
a program for detecting duplicate or very similar images. It maintains a
database of characteristic color samples which it compares with submitted
pictures. similar depends on libjpeg and ImageMagick s convert (on a
modern Linux desktop system these components should already be present).
Storage medium may be a usual filesystem or a MySQL database. There
also is a MySQL UDF extension to compare image samples within SQL queries.
similar contains the communications module described at sagent.
simv
a core program to perform file management tasks on an image collection.
Its main purpose is to coordinate file movements with the content of
similars database. This applies to importing new files which get tested
against the existent collection, as well as to inform similar about moving
and deleting files within the collection.
simv depends on an external image viewer like ImageMagick s display
(should already be present on a modern Linux desktop system) or John
Bradleys xv (quite a fast one).
simv contains the communications module described at sagent.
sagent
a standalone version of the communications module used in simv and
similar. This software receives input from its start terminal and multiple
clients, distributes several types of output back to them, and is also
able to act itself as such a client.
Since communications mainly use TCP/IP there is an encryption layer
(Blowfish with 128 bit keys) which provides user authentication. Any
single activity of such a user may be particularly permitted or denied.
Secure connections should be possible that way as long as one can defend
the keyfiles and programs on client and server host against foreign
access.
Front-end connection software is available in C, Tcl/Tk and PHP3 to build
custom clients. In the most primitive case even telnet can act as a
client.
The standalone program sagent may be used as communications node in a tree
of clients. Another purpose is to be a shell frontend which sends commands
to a server and receives its replies.
snntpbatch
a command line based NNTP (newsgroups) client. It is mainly intended for
automatic download of images by use of a filter language. Nevertheless it
also downloads the message texts and converts them to HTML code which
includes the downloaded images. Also, it is capable of automatically
posting sets of images to the newsgroups.
The tools are designed to be very independent of the system flavor. On an
average Linux desktop there should be no need to update existing system
components. Actually one could use stic without having display equipment for
graphics.
Any program activity which is possible in dialog may also be performed in
batch runs. Therefore the tools are quite suitable for users who like to get
boring tasks automated and manual tasks simplified.
All tools code is open source and distributed under BSD license.

Enhancements:
- The new encrypted protocol version 0.2 is standard now : SHA-1 seal, 256 bit keys, variable chaining initialization vector.
- The protocol of a connection is chosen by the client and may or may not be accepted by the server.
- See sagent command -security options clientprotocol , serverprotocol.

Source Mage GNU/Linux distribution is based on a sorcerous metaphor of "casting" and "dispelling" packages, which we refer to as "spells".
This is a development ISO and potentially loaded with bugs and glitches. This is where you come in. We need your help to squash these bugs.
Please download, burn, and install this ISO to a spare partition, extra computer, or over your least favorite friends Windows partition. VMWare or bochs works too. Upon finding a glitch, please report it in bugzilla. No bug is too small, or too large.
Help shape the future of Source Mage! Download the Next Generation Testing ISO and install!
Enhancements:
- A "dependency" scheme was added to make sure you dont accidentally skip a vital step or do things in the wrong order.
- You can still override dependencies if you really know what youre doing.
- Spells are now installed in the background while you are busy selecting options.
- Software RAID support via mdadm was added.

Open BEAGLE is a C++ Evolutionary Computation (EC) framework. It provides an high-level software environment to do any kind of EC, with support for tree-based genetic programming, bit string and real-valued genetic algorithms, and evolution strategy.
The Open BEAGLE architecture follows strong principles of object oriented programming, where abstractions are represented by loosely coupled objects and where it is common and easy to reuse code.
Open BEAGLE is designed to provide an EC environment that is generic, user friendly, portable, efficient, robust, elegant and free.
With Open BEAGLE, the user can execute any kind of EC, as far as it fulfills some minimum requirements. The only necessary condition is to have a population of individuals to which a sequence of evolving operations is iteratively applied.
So far, Open BEAGLE supports most mainstream EC flavors such genetic programming, bit string and real-values genetic algorithms, and evolution strategy. It also includes support for advanced EC techniques such multiobjective optimization and co-evolution.
The user can take any of these specialized frameworks and modify them further to create his own specialized flavor of evolutionary algorithms.
Main features:
User Friendliness
- Considerable efforts were deployed to make the use of Open BEAGLE as easy and pleasant as possible. Open BEAGLE possesses several mechanisms that offer a user friendly programming interface. For example, the memory management of dynamically allocated objects is greatly simplified by the use of reference counting and automatic garbage collection. The programming style promoted is high-level and allows rapid prototyping of applications.
Portability
- The Open BEAGLE code is compliant with the C++ ANSI/ISO 3 standard. It requires the Standard Template Library (STL). No specific call in the core libraries are made to the operating system nor to the hardware.
Efficiency
- To insure efficient execution, particular attention was given to optimization of critical code sections. Detailed execution profiles of these sections were done. Also, the fact that Open BEAGLE is written in C++ contributes to its overall good performance.
Robustness
- Many verification and validation statements are embedded into the code to ensure correct operation and to inform the user when there is a problem. Robust mechanisms for periodically saving the current evolution state have also been implemented in order to enable automatic restart of interrupted evolutions.
Elegance
- The interface of Open BEAGLE was developed with care. Great energy was invested in designing a coherent software package that follows good OO and generic programming principles. Moreover, strict programming rules were enforced to make the C++ code easy to read, understand and, eventually, modify. The use of XML as file format is also a central aspect of Open BEAGLE, which provide a common ground for tools development to analyze and generate files, and to integrate the framework with other systems.
Free Sourceness
- The source code of Open BEAGLE is free, available under the GNU Lesser General Public License (LGPL). Thus, it can be distributed and modified without any fee. (See section copyright for further details.
Enhancements:
- Several fixes to allow compilation on Mac OS X
- Fixes in headers inclusion to allow precompiled headers
