php_mt_seed finds possible seeds given the very first PHP mt_rand() output after possible seeding with mt_srand(). With advanced invocation modes, php_mt_seed is also able to match multiple, non-first, and/or inexact mt_rand() outputs to possible seed values. php_mt_seed is written in C with optional SIMD intrinsics (SSE4.1/AVX, XOP, AVX2, MIC) and OpenMP. On a modern quad-core CPU, it is able to search the full 32-bit seed space in one minute (or in just seven seconds on Xeon Phi).
libtld is a library used to extract the TLD from a URI and to check email validity. This allows you to extract the exact domain name, sub-domains, and all the TLD (top level, second level, third level, etc.). The problem with TLDs is that you cannot know where the domain starts. Some domains can use one top-level domain, others use two, etc. However, it may be useful to know where the domain is to have the exact list of sub-domains. For example, if you want to force www. at the start of the domain name if no other sub-domains are specified, then you need to know exactly how many TLD are defined in a URI. The libtld offers one main function: tld(), which gives you a way to extract the TLD from any URI. The result is the offset where the TLD starts. This gives you enough information to extract everything else you need. For emails, the library is capable of parsing a string that represents a list of email addresses to be verified. The verification includes a check of the domain name and its TLD.
OSCATS (Open-Source Computerized Adaptive Testing System) implements Item Response Theory (IRT) and cognitively diagnostic (latent classification) models and item selection algorithms used in Computerized Adaptive Testing (CAT). OSCATS facilitates the development of CATs and simulations of CATs by providing ready-to-use code for running the CAT item selection and ability/classification estimation in an extensible, modular framework. The library is written in object-oriented C using GObject, and has bindings to Python, Perl, PHP, and Java.
lib4d_sql is a C library that provides the required functions (connect, prepare, execute, etc.) for writing an SQL client for 4D databases. It uses the public 4D SQL protocol, which is supported by 4D products since version 11. It is already used by the PDO_4D Open Source project, and it might be used to provide others drivers for JDBC, ADO, or ActiveRecord.
VersyPDF is a set of the high-quality, industry-strength PDF libraries that meet the requirements of very demanding and diverse applications. It is compatible with a lot of operating systems and programming languages. The supported programming languages are C/C++, Delphi, .NET, Perl, and PHP.
Suhosin is an advanced protection system for PHP installations. It was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts that can be used separately or in combination. The first part is a small patch against the PHP core that implements a few low-level protections against buffer overflows or format string vulnerabilities. The second part is a powerful PHP extension that implements all the other protections. Suhosin is binary compatible with plain PHP installations.
Visual Paradigm for UML is a Unified Modeling Language (UML) design tool that supports all UML diagrams, SysML diagrams, and entity relationship diagrams. Visual Paradigm for UML provides extensive use case modeling features, including full function UML use case diagrams, a flow of events editor, use case/actor grid, and activity diagram generation. Visual Paradigm for UML produces system documentation in PDF, HTML, and MS Word formats. A developer can design system documentation with the template designer. A system analyst can estimate the consequences of changes with impact analysis diagrams, such as matrix and analysis diagram. Visual Paradigm for UML generates Java code.
Stunnix Advanced Web Server is a Web server for putting Web sites onto CD-ROMs, DVDs, FlashDisks, and other readonly media to be used on any typical system. Sites can be scripted with PHP, Python, Java, or Perl and can be driven by MySQL or SQLite databases. All required software programs are designed to reside on the CD-ROM to avoid the need to install software on the user's computer. The Web serving core is based on Apache 1.3.x, and has additional functionality to detect and use free ports and automatically start a browser on each platform. Desktop applications can also be created with it.
basE91 is an advanced method for encoding binary data as ASCII characters. It is similar to UUencode or base64, but is more efficient. The overhead produced by basE91 depends on the input data. It amounts at most to 23% (versus 33% for base64) and can range down to 14%, which typically occurs on 0-byte blocks. This makes basE91 very useful for transferring larger files over binary unsafe connections like e-mail or terminal lines.
