Free public computing software for linux

PaiPix Linux is a compilation of Free Software, based on KNOPPIX live linux, that is meant to be used in any environment but with special emphasis on science and technologies.
PaiPix Linux should provide an open door to the public including not only the tolls used by the scientists but also the best free applications that make your computer more interesting for any usage.
If you like it for office, video or even gaming, who knows if someday you can get curious and give a look at the scientific applications that are in your DVD.
PaiPix can be used at home, in medium and even large size organizations where the sharing of the compressed DVD image and the included afs file system support make it extreemely powerfull.
PaiPix Linux also serves to support clusters of distributed computing (using the paipix-terminalsever), for data servers, farms simulation farms and user laboratories.
PaiPix linux combines all the versatility of KNOPPIX with optimized configuration for several languages, including Portuguese. It intends to not only serve in document editing tasks but also for advanced technological and scientific systems.
Using the paipix-remaster script, you can change the default language of your iso image or add your personal files to the PAIPIX DVD.
This work was only possible because Free Software experts have created all the infrastructure allowing a gigantic world-wide community of software volunteers develop what is already, without any doubt, the best operative system the world.
However, because (r)evolutions take time, many companies that are developing systems - which in the end are designed to store in practice the technological and scientific knowledge of mankind - still work in a closed form (proprietary).
There is still a reason to use other operative systems while the community of free software does not this knowledge to the whole humanity. In the following table we include a correspondence that facilitates the migration to free software for each application. All mentioned free software is installed in PaiPix!
This software is distributed without any guarantee if not the fact that a great number of components are permanently being used and tested by millions of people in the whole world.
Based on Knoppix 3.8, including kernel 2.6.11. It uses the Unionfs file system that mounts the DVD image in read-write mode. Using this feature, PAIPIX can run your 3D-enabled drivers for ATI or NVIDIA cards. Just use knoppix install=ati or knoppix install=nvidia as boot option and run the FlightGear simulator (fgfs) to see the new fantastic 3D support in Linux
Enhancements:
- The new PAIPIX 7 keeps its focus on scientific software but drops the emphasis on a pure live DVD to integrate installation, live and upgrade systems. The new main use cases are: LIVE - starting PAIPIX in the live mode, one has access to complete system including KDE, office and development; INSTALLATION - by starting PAIPIX in the installation mode one has access to the standard Debian installer system; UPGRADE - as part of the entire system, the DVD includes a Debian CD-ROM repository that includes all necessary packages. The PAIPIX ISO images are available in English and in bilingual editions that support both English and one of the following languages: Portuguese, Spanish, French, Italian and German.

CreditCruncher computes the Value At Risk (VAR) of large credit portfolios using the Monte Carlo method.
CreditCruncher is a command line solver that read an xml input file and returns a plain text file with the simulated values of portfolio. The current version is 0.8. This software is released under the GNU General Public License.
CreditCruncher is designed to work in batch mode, without graphical support. Computation time can be reduced enabling the MPI instructions when compiling and deploying the application in a cluster.
The user create a xml file where the portfolio is described. CreditCruncher take this file and simulate N times the portfolio described in the input file. The simulated values are stored in a file with extension .out. Finally, a R script takes the simulated values and do some statistic over there to generate the risk indicators (VaR, TCE, etc.)
Enhancements:
- Documentation rewrited and translated to english
- Modified asset losses computation algorithm
- solved minor bugs
- added minor enhancements
- changed site look & feel

OpenSSH LDAP Public Key patch provides an easy way of centralizing strong user authentication by using an LDAP server for retrieving public keys instead of ~/.ssh/authorized_keys.
It uses the standard core.schema/nis.schema and strongAuthenticationUser object class, which can simplify login centralization but could introduce serious security flaws if the LDAP server is not correctly configured.
Enhancements:
- A memory leak has been fixed.
- A potential LDAP filter injection if a username has strange characters in it [()*] has been fixed.

CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor.
CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) CentOS is free, however, we ask for a small contribution. CentOS is a project of the cAos Foundation.
CentOS is developed by a small but growing team of core developers. In turn the core developers are supported by an active user community including system administrators, network administrators, enterprise users, managers, core Linux contributors and Linux enthusiasts from around the world.
CentOS has numerous advantages over some of the other clone projects including: an active and growing user community, quickly rebuilt, tested, and QAed errata packages, an extensive mirror network, developers who are contactable and responsive, multiple free support avenues including IRC Chat, Mailing Lists, Forums, a dynamic FAQ. Commercial support is offered via a number of vendors.
CentOS exists to provide a free enterprise class computing platform to anyone who wishes to use it. CentOS 2 and 3 are fully compatible rebuilds of RHEL 2 and 3 respectively. CentOS 2 and 3 are reproduced from RHEL sources that are freely distributed by RedHat.
Redistributed packages and sources comply fully with RedHats redistribution requirements. CentOS 2 and 3 are designed for people who need an enterprise class OS without the cost, support, certification, or brand name of RedHat.
Main features:
- easy maintenance
- suitability for long term use in production environments
- friendly environment for users and package maintainers
- long-term support of the core
- active development
- community infrastructure
- open management
- open business model
- commercial support - offered by a partner vendor
Enhancements:
- We are pleased to announce the immediate availability of CentOS 5 for the i386 and x86_64 architectures. CentOS 5 is based on the upstream release 5, and includes packages from all variants including Server and Client. All upstream repositories have been combined into one, to make it easier for end users to work with. Major changes in CentOS 5 compared to CentOS 4 include: updated software versions; better desktop support with Compiz and AIGLX; virtualization provided by the Xen hypervisor with Virtual Machine Manager and libvirt; Sabayon to simplify the construction of user profiles.

Hub::Perl::Language is a Perl module that contains a lot of methods.

PUBLIC METHODS

sizeof

Integer size of hashes, arrays, and scalars

Usage: sizeof %hash
Usage: sizeof @array
Usage: sizeof $scalar_ref
Usage: sizeof $scalar
Usage: sizeof %more, @than, $one

Sizes are computed as follows:

HASH - Number of keys in the hash
ARRAY - Number of elements
SCALAR - Length as returned by C

The total size of all arguments is returned.

Example: Hash: (matches)

sizeof( { a=>1, b=>2, c=>3 } );


3
Example: Array: (matches)
sizeof( [ a1, b2, c3 ] );


3
Example: Scalar: (matches)
sizeof( "abc" );


3
Example: Scalar (ref): (matches)
sizeof( "abc" );


3
Example: Nothing: (matches)
sizeof( undef );


0
Example: Multiple values: (matches)
sizeof( "a", "b", "c" );


3
check

True if all items in list pass the test.
Usage: check [OPTIONS], [TEST], LIST
