Armangils podcatcher is a podcast client for the command line. It provides several download strategies (new shows only, back-catalog allowed, etc), supports BitTorrent, offers cache management, and generates playlists for MP3 player applications.
Armangils podcatcher project is written in Ruby, and runs on Linux (tested), MacOS, Windows and many other operating systems.
Usage is fairly straightforward: podcatcher subscriptions.opml > latest.m3u downloads the latest subscribed podcasts into the current directory and generates a playlist.
OPML URLs are also allowed as parameters, so that listening to the most popular podcasts is as easy as typing something like podcatcher http://podcastalley.com/PodcastAlleyTop50.opml > latest.m3u.
For help, use podcatcher -h.
Enhancements:
- This release adds the --cachedir option for explicitly specifying the content cache directory independently from the state directory (specified using --dir), the --language option for selecting feeds by language, the --horizon option that prevents the downloading of content older than a given date, the --restrictednames option for using content file names that are acceptable for restrictive filesystems such as VFAT, and more robust handling of feeds that use the Media RSS module.
- A bug in update checking has been fixed.

SEOlizer is a GPL application that generates web pages of analysis, from webserver log files (Apache, etc). The seolizer is based on the webalizer code.
Please note that the code is one-night hack, from my point of view its a very very poor quality! It is not recommended to run seolizer on a production server. I have published the seolizer to get some feedback from SEO community. Stable version will be available in several months, after I make clear decision how to implement all required features. Your feedback is appreciated !
Compile seolizer by running make all -C src. Then you can run it using ./seolizer [logfile]. Output will be placed in the current directory.
SEOlizer functions
Web spiders daily/monthly crawling reports (incl. bots IP addresses)
Keyword and phrase analysis, displays pages that matched query
Most popular pages for search engine query results and relevant keywords and phrases
Fully static HTML
About SEO
Search engine optimization (SEO) as a subset of search engine marketing seeks to improve the number and quality of visitors to a web site from "natural" ("organic" or "algorithmic") search results. The quality of visitor traffic can be measured by how often a visitor using a specific keyword leads to a desired conversion action, such as making a purchase or requesting further information. In effect, SEO is marketing by appealing first to machine algorithms to increase search engine relevance and secondly to human visitors.
Enhancements:
- Pagerank support was added along with support for www.rankcheck.info.
- The code was cleaned up and better HTML was implemented.

Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. Bochs project includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS.

Currently, Bochs can be compiled to emulate a 386, 486, Pentium, Pentium Pro or AMD64 CPU, including optional MMX, SSE, SSE2 and 3DNow! instructions.

Bochs is capable of running most Operating Systems inside the emulation including Linux, Windows 95, DOS, and Windows NT 4. Bochs was written by Kevin Lawton and is currently maintained by this project.

Bochs can be compiled and used in a variety of modes, some which are still in development. The typical use of bochs is to provide complete x86 PC emulation, including the x86 processor, hardware devices, and memory.

This allows you to run OSs and software within the emulator on your workstation, much like you have a machine inside of a machine. For instance, lets say your workstation is a Unix/X11 workstation, but you want to run Win95 applications.

Bochs will allow you to run Win 95 and associated software on your Unix/X11 workstation, displaying a window on your workstation, simulating a monitor on a PC.

BBCode::Parser is a Perl module that parses BBCode tags.

BBCode is a simplified markup language used in several online forums and bulletin boards. It originated with phpBB, and remains most popular among applications written in PHP. Generally, users author their posts in BBCode, and the forum converts it to a permitted subset of well-formed HTML.
BBCode::Parser is a proper recursive parser for BBCode-formatted text.

OVERVIEW

A BBCode::Parser object stores various settings that affect the parsing process. Simple settings are typically set when the parser is created using new(), but they can be queried using get() and altered using set().

See "SETTINGS" for more information.

In addition to the simple settings, specific BBCode tags (or classes of tags) can be permitted or forbidden, using permit() and forbid() respectively. By default, the only forbidden tag is [HTML], which is normally a security violation if permitted.

See "CLASSES" for a list of tag classes.

Once the parser has been configured appropriately, parse trees can be created using the parse() method. The parse tree will consist of objects derived from BBCode::Tag; the root of the tree will be a BBCode::Body object.

Converting the parse tree to HTML is quite simple: call toHTML() on the root of the tree. Likewise, the parse tree can be converted back to BBCode by calling toBBCode(). See "METHODS" in BBCode::Tag to find out what other output methods are available.
