Wide Area Link Emulator enables you to set and test various parameters of a WAN access link (also known as a bottleneck link) before testing on a fully-functional network.

Any ISP has a high bandwidth LAN (of the order of tens of Mbps, e.g. Ethernet) and a WAN access link with relatively low speeds (of the order of a few Kbps to a few Mbps). To be able to evaluate the ISPs performance, actual tests will have to be conducted on a live, fully functional network. This would imply enabling certain features in communication equipment which could be detrimental to the proper functioning of a commissioned network. To address such a problem of being able to characterize/quantify the network operation in terms of its performance with respect to various parameters, a test-bed emulating the ISPs connectivity to the Internet would be an ideal solution.

An important factor in setting up such a test-bed, is emulating the WAN Access Link. Using complex hardware is costly. Such a link can however be easily implemented by emulating the scenario on popular physical technology such as Ethernet. By changing the TCP/IP stack on a Personal Computer, the rate at which packets are injected into the network can be controlled and other necessary features can easily be added.

WALE was implemented in 2 phases and the first version can emulated bandwidths up to 8Mbps and uses FIFO queues with drop-tail.

WALE v2 can emulate bandwidths of up to 80Mbps(a 10-fold improvement over version 1) due to the stripped down version of Micro-second resolution timer being used in the Linux kernel. WALE also implements differentiated services are recommended by IETF. A hash-based packet classifier is used to classify packets into one of 3 queues (Expedited Forwarding, Assured Forwarding and Best Effort). A simple priority scheduling has been implemented between the queues.

Version 2 has been implemented in the Generic Device Layer of the Linux Kernel. The kernel version is 2.2.19. WALE2 kernel patch can be downloaded here. An ncurses based front end has been implemented for setting and viewing various parameters of the bottleneck link.

Strato Log Download is a small Perl script intended to download logfiles from Web accounts from Strato hosted sites.
The problem is that the normal download interface is interactive, and that only about six weeks are kept on the server. So without scripting, youre likely to lose valuable log information (at least I was unable and unwilling to remember to download the logfiles once every six weeks).
This script logs in via the SSL-encrypted web-interface and downloads the files without needing a web-browser (proxies are configurable via the https_proxy environment variable).
Note: For SSL support, you might need additional Perl modules since some distros dont include crypto stuff: either use IO::Socket::SSL or Net::SSL (in Crypt::SSLeay).
If an SSL module is missing, https access will not work.
Usage is very easy:
$ get-logfiles -p mypassword www.mysite.de > logfile.gz
Enhancements:
- Feature: a new logfile download protocol was necessary, because the web interface changed (thanks to J. Puchalla for telling me -- it would probably have gone unnoticed otherwise).

VT6530 Terminal Emulator is a Java implementation of the proprietary terminal used with Tandem mainframes.
The Tandem VT6530 is a proprietary terminal used with their Non-Stop(TM) series of mainframes. These high-reliability machines are popular in the banking industry. If youve ever used an ATM to get cash, youve probably used a VT6530.
The terminal itself can operate in three different mode: conversation, block, and ANSI (VT100). Conversation mode is a simple scrolling text mode with the addition key buffering and text attributes. In block mode, text is displayed in a formated screen with special edit fields. ANSI mode is only used with OSS, Tandems UNIX wanabe operating layer.
Enhancements:
- Autotools support (./configure, make, make check, and make install).
- New telnet and ANSI terminal implementations.
- Linux, Cygwin, and HP NonStop (tandem OSS) builds are not quite running yet.

cereal is an emulation framework designed to allow easy emulation of interconnected modules. Its main component is an 8051 emulator module, so it can be used as an 8051 emulator.

The reason for writing cereal was an 8051 embedded controller which should control an engine using pulse-width modulation, read the resulting flow from a flowmeter, and regulate the output to keep flow at a given value.

In the real world, it takes about two seconds for the algorithm to stabilize, and emulating two seconds using conventional emulators (computing the engine input, the real flow, the feedback frequency) by hand is simply impossible to do.

Using cereal, it took about two hours to create a module emulating the engine/flowmeter combination, along with a window showing the current values. Then it is trivial to connect this module to the 8051 module and just sit back and watch the result.

Another, more trivial example is a multiplexed display/keyboard combination (in my case, selecting one of four 8-segment LCD displays). Instead of watching the port bits, why not create a module that shows the output graphically as four displays?

In addition to these possibilities, cereal offers breakpoints, watches, evaluate/modify dialog (which can solve 2 * x + 1 = 5). The KDE GUI also can be extended using KParts (8051 interface is provided as a KParts plugin).

Also included is a command interface usable for creating testsuites for your programs (or for cereal itself - cereal has over 400 tests in its testsuite), and a simple 8051 disassembler.

Batch Download is a plugin for Firefox that makes downloading multiple images easy.

Like FlashGets batch download,but special designed for some image site!

You will find it very useful when you download some url like

http://www.google.com/1.jpg
http://www.google.com/2.jpg
http://www.google.com/3.jpg...

or some other urls like:

http://www.google.com/0102.jpg
http://www.google.com/0203.jpg
http://www.google.com/0304.jpg...

And also you can download all images in current page at once.

Download Sentinel++ is an Anti-leech, download limiter / file manager, that uses tokens to verify downloads instead of HTTP_REFERER or IP which can be spoofed or changed.
The install is as painless as possible with only one file to upload and execute. The install automatically creates the sub-directories and files, all you need to do is follow the on-screen instructions for permissions.
Security has been the focus throughout development, even the install program is built on the latest recomendations for security. Logging is done with text files and can have errors and alerts sent via email or stored in a txt file.
Downloads can be limited to a certain transfer size per time frame, which can be further broken down into smaller intervals, all with only a couple settings. This helps spread out the limitation to different timezone and prevents all available bandwidth being used in a short period
Main features:
- Completely free (free as in speech);
- Multiple language capability (all text is in config file, no hardcoded messages);
- Download counter file;
- xhtml/css compliant message output, fully customizable;
- Install script for easy setup;
- All user supplied input securely handled;
- Uses tokens to validate download requests. A superior method than .htaccess or http_referer which can be spoofed or limit users with firewalls;
- Tokens are good for a day by default, but can be set to expire at any time in 1 minute increments;
- A log is kept of invalid token attempts and information on tracking down the source;
- All errors and warnings can be written to a log file or sent to an email address;
- Supports unlimited directory structure of downloadable files (no need to specify where a file is located);
- Option to turn off bandwidth protection;
- Option to turn off any error/log report;
- Robust error handling;
- Ability to specify the total amount of transfer (bandwidth) allowed, over the total amount of time;
- Ability to specify interval lengths for download cut-off so all the allowed bandwidth does not go to one time zone / day /hour;
- Ability to put in a ratio of download clicks to actual bandwidth used;
- Log of all download details kept;
- Download log can be auto-archived;
- Ability to specify the download log size before archive;
