A Three-Dimensional Structural Finite Element Program CalculiX Finite Element Models can be build, calculated and post-processed. The pre- and post-processor is an interactive 3D-tool using the openGL API. Notice: The authors acknowledge that naming conventions and input style formats for CalculiX are based on those used by ABAQUS, a proprietary, general purpose finite element code developed and supported by Hibbitt, Karlsson & Sorensen, Inc (HKS) and are used with kind permission from HKS. Results obtained from CalculiX are in no way connected to ABAQUS. note: By default the single-threaded solver is used, this can be changed by setting the OMP_NUM_THREADS environment variable with the number of processors you want to use.

With Glom you can design table definitions and the relationships between them, plus arrange the fields on the screen. You can edit and search the data in those tables, and specify field values in terms of other fields. It's as easy as it should be. The design is loosely based on FileMaker Pro, with the added advantage of separation between interface and data. Its simple framework should be enough to implement most database applications. Without Glom these systems normally consist of lots of repetitive, unmaintainable code. Glom-specific data such as the relationship definitions is saved in the Glom document. Glom re-connects to the database server when it loads a previous Glom document. The document is in XML format. Glom uses the PostgreSQL database backend but it can not edit databases that it did not create, because it uses only a simple subset of Postgres functionality.

GNU Recutils is a set of tools and libraries to access human-editable, text-based databases called recfiles. The data is stored as a sequence of records, each record containing an arbitrary number of named fields. Advanced capabilities usually found in other data storage systems are supported: data types, data integrity (keys, mandatory fields, etc) as well as the ability of records to refer to other records (sort of foreign keys). Despite its simplicity, recfiles can be used to store medium-sized databases. Recfiles are human-readable, human-writable and still they are easy to parse and to manipulate automatically. Obviously they are not suitable for many tasks (for example, it can be difficult to manage hierarchies in recfiles) and performance is somewhat sacrificed in favor of readability, but they are quite handy to store small to medium simple databases.

MooseX::NonMoose allows for easily subclassing non-Moose classes with Moose, taking care of the annoying details connected with doing this, such as setting up proper inheritance from Moose::Object and installing (and inlining, at make_immutable time) a constructor that makes sure things like BUILD methods are called. It tries to be as non-intrusive as possible - when this module is used, inheriting from non-Moose classes and inheriting from Moose classes should work identically, aside from the few caveats mentioned below. One of the goals of this module is that including it in a Moose::Exporter-based package used across an entire application should be possible, without interfering with classes that only inherit from Moose modules, or even classes that don't inherit from anything at all.

This is PIRE, Perl Incompatible Regular Expressions library. This library is aimed at checking a huge amount of text against relatively many regular expressions. Roughly speaking, it can just check whether given text maches the certain regexp, but can do it really fast (more than 400 MB/s on our hardware is common). Even more, multiple regexps can be combined together, giving capability to check the text against apx.10 regexps in a single pass (and mantaining the same speed). Since Pire examines each character only once, without any lookaheads or rollbacks, spending about five machine instructions per each character, it can be used even in realtime tasks. On the other hand, Pire has very limited functionality (compared to other regexp libraries). Pire does not have any Perlish conditional regexps, lookaheads & backtrackings, greedy/nongreedy matches; neither has it any capturing facilities.

Portable libumem. ================ This is a port of Solaris libumem to non-Solaris systems. The port was made while integrating libumem with our Ecelerity MTA product, so your initial experience will not be 100% out-of-the-box, because there is no standalone configure script for the library at this time. (patches welcome!) In addition, since our deployment is threaded, we force the library into threaded mode. While the library is itself stable (it's the memory allocator used by the Solaris OS), the port may have a few rough edges. We're shipping umem with Linux and Windows versions of our product as we have found it to be stable. We will continue to update this project as and when we make improvements, and welcome third-party patches that improve the usability for everyone. Wez Furlong, OmniTI, Inc.

GNU wget is a free software package for retrieving files using HTTP, HTTPS and FTP, the most widely-used Internet protocols. It is a non-interactive command-line tool, so it may easily be called from scripts, cron jobs, terminals without X-Windows support, etc. GNU wget has many features to make retrieving large files or mirroring entire web or FTP sites easy, including: o Can resume aborted downloads, using REST and RANGE o Can use filename wild cards and recursively mirror directories o NLS-based message files for many different languages o Optionally converts absolute links in downloaded documents to relative, so that downloaded documents may link to each other locally o Supports HTTP and SOCKS proxies o Supports HTTP cookies o Supports persistent HTTP connections o Unattended / background operation o Uses local file timestamps to determine whether documents need to be re-downloaded when mirroring o GNU wget is distributed under the GNU General Public License.

The FlightGear flight simulator project is an open-source, multi-platform, cooperative flight simulator development project. Source code for the entire project is available and licensed under the GNU General Public License. The goal of the FlightGear project is to create a sophisticated flight simulator framework for use in research or academic environments, for the development and pursuit of other interesting flight simulation ideas, and as an end-user application. We are developing a sophisticated, open simulation framework that can be expanded and improved upon by anyone interested in contributing. There are many exciting possibilities for an open, free flight sim. We hope that this project will be interesting and useful to many people in many areas.

Litecoin is a peer-to-peer Internet currency that enables instant payments to anyone in the world. It is based on the Bitcoin protocol but differs from Bitcoin in that it can be efficiently mined with consumer-grade hardware. Litecoin provides faster transaction confirmations (2.5 minutes on average) and uses memory-hard, scrypt-based mining proof-of-work algorithm to target the regular computers and GPUs most people already have. The Litecoin network is scheduled to produce 84 million currency units. One of the aims of Litecoin was to provide a mining algorithm that could run at the same time, on the same hardware used to mine bitcoins. With the rise of specialized ASICs for Bitcoin, Litecoin continues to satisfy these goals. It is unlikely for ASIC mining to be developed for Litecoin until the currency is widely used.
