Kalzium is your digital replacement for the periodic table on paper. It is a program that visualizes the periodic table of elements (PSE) and includes basic information about all common elements in the PSE. It has gained much more functions over time. FEATURES - Versatile overview of all important data from the elements like melting points, electron affinity, electron negativity, electron configuration, radii, mass, ionisation energy. - Tool to visualize the spectral lines of each element. - Different colored views for the PSE: separation of the different blocks, year simulator, temperature simulator. - Molecular weight calculator. - An isotope table. - 3D molecule editor, with a load and save functionality. - An equation solver for stoichiometric problems. - Filetype conversion for different types of chemical programs. - Tool to produce a comprehesive list of all risk and safety statements.

NCrypt is intended to give you security in an insecure environment. If you are wanting to encrypt files (particularly on a multi-user system where you don't have root), wishing to hide your activites from prying eyes, and want to "cover your tracks", then NCrypt is for you. It is a symmetrical file encryptor/decryptor that gives you the choice of the top three candidates for AES as the encryption algorithm (Rijndael, Serpent, Twofish), tries to minimize exposure of the plaintext password in memory, and can safely erase the plaintext version from the hard drive. It compiles without any extra crypto libraries, making it ideal for systems where you just have a compiler and basic libraries (such as an ISP's shell server).

Spinner is a small program that displays a little "spinning" ASCII character in the top left corner of your terminal. To make this effect it cycles through punctuation marks like this " - \ | / - \ | / ... " (try it to see). By default the character is drawn in inverse video (or your terminal's equivalent). But you can turn this off with the -i switch. It supports any terminal capable of handling VT100 style escape codes. Spinner is useful for keeping telnet and ssh links from dropping due to inactivity. Many firewalls, and some ISPs drop connections when they are perceived as idle. By having spinner running the server is constantly sending a tiny amount of data over the link, preserving the connection. Thus (for search engines) Spinner is an anti-dle, timeout preventing, background daemon process for Unix variants including Linux. - Michael L. Hostbaek mich@FreeBSD.org

The Petal::Utils package contains commonly used Petal modifiers (or plugins), and bundles them with an easy-to-use installation interface. By default, a set of modifiers are installed into Petal when you use this module. You can change which modifiers are installed by naming them after the use statement: # use the default set: use Petal::Utils qw( :default ); # use the date set of modifiers: use Petal::Utils qw( :date ); # use only named modifiers, plus the debug set: use Petal::Utils qw( UpperCase Date :debug ); # don't install any modifiers use Petal::Utils qw(); You'll find a list of plugin sets throughout this document. You can also get a complete list by looking at the variable: %Petal::Utils::PLUGIN_SET; For details on how the plugins are installed, see the "Advanced Petal" section of the Petal documentation.

Greeking is the use of random letters or marks to show the overall appearance of a printed page without showing the actual text. Greeking is used to make it easy to judge the overall appearance of a document without being distracted by the meaning of the text. This is a module is for quickly generating varying meaningless text from any source to create this illusion of the content in systems. This module was created to quickly give developers simulated content to fill systems with simulated content. Instead of static Lorem Ipsum text, by using randomly generated text and optionally varying word sources, repetitive and monotonous patterns that do not represent real system usage is avoided.

The Translate Toolkit is a set of software and documentation designed to help make the lives of localizers both more productive and less frustrating. The software includes programs to covert localization formats to the common PO format and programs to check and manage PO files. The documentation includes guides on using the tools, running a localization project and how to localize various projects from OpenOffice.org to Mozilla. At its core the software contains a set of classes for handling various localization storage formats: DTD, properties, OpenOffice.org GSI/SDF, CSV and of course PO and XLIFF. It also provides scripts to convert between these formats. Also part of the Toolkit are Python programs to create word counts, merge translations and perform various checks on PO and XLIFF files.

Elasticsearch DSL is a high-level library whose aim is to help with writing and running queries against Elasticsearch. It is built on top of the official low-level client (elasticsearch-py). It provides a more convenient and idiomatic way to write and manipulate queries. It stays close to the Elasticsearch JSON DSL, mirroring its terminology and structure. It exposes the whole range of the DSL from Python either directly using defined classes or a queryset-like expressions. It also provides an optional wrapper for working with documents as Python objects: defining mappings, retrieving and saving documents, wrapping the document data in user-defined classes. To use the other Elasticsearch APIs (eg. cluster health) just use the underlying client.

Trac 使用较低门槛的方法来实施基于 web 的软件项目管理。我们的使命是，帮助开发者 编写出很好的软件。Trac 应该尽可能少地改变团队已有的开发过程和策略。 Trac 的所有方面都符合一个单一的目标，简化跟踪和软件问题的交流，增强和监测整个进程。 Trac 是什么？ * 一个管理软件项目的集成系统 * 一个增强的 wiki * 一个灵活的基于 web 的问题跟踪器 * 一个 Subversion 版本控制系统的界面 Trac 的核心在于集成 wiki 和问题/bug 数据库。使用 wiki 标记，所有管理的对象 都可以直接连接到其他的问题/bug 报告、代码变更集、文档和文件。

Ever tried logging Apache page serve times using '%D'? You'll have discovered that they aren't a good index of your server's performance, because they depend more on the client's connection speed, computer and browsing habits than on the speed of your server. mod_log_firstbyte is a module for Apache 2.0 which allows you to log the time between each request being read and the first byte of the response served. Unlike the total serve time, this index of performance tells you how long Apache actually spent loading the file off the disk or executing your script: it's independent of client connection speed. It makes a great performance benchmark for your server!

The crawl utility starts a depth-first traversal of the web at the specified URLs. It stores all JPEG images that match the configured constraints. Crawl is fairly fast and allows for graceful termination. After terminating crawl, it is possible to restart it at exactly the same spot where it was terminated. Crawl keeps a persistent database that allows multiple crawls without revisiting sites. The main reason for writing crawl was the lack of simple open source web crawlers. Crawl is only a few thousand lines of code and fairly easy to debug and customize. Some of the main features: - Saves encountered JPEG images - Image selection based on regular expressions and size contrainsts - Resume previous crawl after graceful termination - Persistent database of visited URLs - Very small and efficient code - Supports robots.txt
