[[Concept:Internet-application]]

Autohosts: Hosts files will reroute unwanted traffic from ad farms, behavioral tracking firms and malware sites to a blackhole; routing to 0.0.0.0 (localhost; your PC) when a request is made to a URL on the blacklist. Which means any traffic that would have left your system for that destination, is sent inward, to your localhost and then abandoned. Despite what some may suggest, hosts files are not "1980s technology" and still very useful today, as an additional layer of security. Hosts file are a useful redundancy when coupled with ad blockers like uBlock Origin and uMatrix - while debugging or 'Temporarily Allow All on this Site' with Noscript can open you up to underlying attacks or privacy intrusions. In-browser filters won't protect you if the browser itself is phoning home. If you have an up-to-date hosts file, the risk is severely lessened. Auto Hosts will automate the setup process for maintaining an up to date hosts file, by: - Installing a weekly cronjob to pull fresh/updated copies of hosts lists (default is every Sunday at 7:22pm) (Default custom_filters and firefox-includes) source appends Facebook trackers, Linkedin ads, Google fonts, Firefox telemetry and other harvester sites that curated lists for whatever reason, have not added to their blacklists - Refreshes DNS to instantiate the re-routed changes (Mac Only) If Devdom is installed, append all local virtualhosts (if it is installed - it is -not- a requirement! Autohosts does a conditional check to ensure your dev environment doesn't break if you're using Devdom. Read the code.) - Uninstall offers the ability to revert to a fresh hosts file and undo any changes made by Autohosts; a backup will be copied to /tmp - Add custom blacklists, whitelists and host sources from ~/autohosts on your desktop

Autossh: Autossh is a program to monitor and automatically reestablish SSH connections. It is similar to rstunnel (Reliable SSH Tunnel), but is easier to set up and use, especially for connections to multiple hosts. The program monitors connections by using a loop of port forwardings, and will back off on the rate of connection attempts when experiencing rapid failures (such as connection refused).

Avahi: Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. This enables you to plug your laptop or computer into a network and instantly be able to view other people who you can chat with, find printers to print to or find files being shared. Compatible technology is found in Apple MacOS X (branded "Bonjour" and sometimes "Zeroconf"). Avahi is primarily targetted at GNU/Linux systems and ships by default in most distributions. It is not ported to Windows at this stage, but will run on many other BSD-like systems. The primary API is D-Bus and is required for usage of most of Avahi, however services can be published using an XML service definition placed in /etc/avahi/services. See also the nss-mdns project, which allows hostname lookup of *.local hostnames via mDNS in all system programs using nsswitch

Awhttpd: 'Anti-Web httpd' is a single-process Web server that relies on its inherent simplicity to be robust and secure. It has support for virtual hosts, CGI, IPv6, and more. In its default mode, though, it is easy to launch and requires no configuration files. It implements the bare minimum of HTTP 1.1 necessary to be a productive web server. It doesn't support certain requests like HEAD (anymore), but normal users will never notice the difference. POST request support is in the works, as is HTTPS/SSL support.

BAD HARVEST: BAD HARVEST is a form-mail CGI script designed to be called from links similar to "mailto:...". It helps you to hide email addresses from "harvesters" (automated email-address collectors) while still providing a convenient way for your visitors to contact you.

BIRD: BIRD is a dynamic routing daemon for UNIX-like systems. It should support all routing protocols used in the contemporary Internet, such as BGP, OSPF, RIP, and their IPv6 variants. It also has a very flexible configuration mechanism, and a route filtering language.

BW whois 2: BW whois is a whois client that works as a command line tool or as a Web application. It includes configurable with self-detecting CGI support, multiple security options in the CGI mode, a mature TLD table, database caching (using MySQL), and many more options and features.

Balance: Balance is a simple but powerful generic TCP proxy with round-robin load balancing and failover mechanisms. Its behaviour can be controlled at runtime using a simple command line syntax.

BannerKiller: BannerKiller is a very simple HTTP proxy that lets you filter pages by forbiding pages whose URLs match some pattern. It can be used for censorship or to filter ads, and is particularly valuable for people with slow connections who normally have to wait for banner ads to download before they can view a page. The software is no longer currently being developed; the authors suggests the program SwiftSurf in place of bannerkiller.

BasE91: '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 insecure connections like e-mail or terminal lines.

Basapp: BasApp is a software for friendly creation of web applications, based on your own database structure. Once BasApp is installed in a webserver, the developer can do all the job with a web browser, same as final user.

Bibliogram: Bibliogram works without browser JavaScript, has no ads or tracking, and shows no pop-up that prevents you to view content without an account. It is inspired by Invidious. A list of available instances can be found here. See Bibliogram-specific and Instagram-related features here.

Bigboos: Bigboos is a network monitoring system that pools devices based on configuration. It is designed to allow mid-sized ISPs to monitor their network and central offices whose branch offices are connected on T1 or E1 lines to monitor their clients and branches. It is based on ICMP and SNMP. A small customer database manager is included. It has the capability to generate and manage trouble tickets, provides the current status about devices being monitored, and generates downtime reports.

BioMail: BioMail automates searching for recent scientific papers in the PubMed Medline database, and can periodically run a customized Medline search and send all recent matching articles to the user's e-mail address. You can save search patterns: no more remembering which search was good and which wasn't. It is intended for medical researchers, biologists, and anyone who wants to know the latest information about a disease or a biological phenomenon. It is also useful for users who have email address but slow or sporadic Web access; they can set up searches and have them emailed to an address instead of having to surf the Web themselves for the information.

Bitcoin-Qt: Bitcoin-Qt is a multiplatform bitcoin client and wallet. Bitcoin is a network and a currency establishing a PKI for electronic cash transactions which is distributed P2P. To quote the developers, "Bitcoin is a decentralized P2P electronic cash system without a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of the network to check for double-spending."

Bitflu: Bitfu is a BitTorrent client designed to run non-stop as a daemon. It does not provide a graphical interface, but offers a telnet interface and can handle multiple torrent downloads.

Bitwarden-ruby: bitwarden-ruby is a server application for storing credentials, especially web-based login details. It includes an independent API reference. Compatible browser plugins can retrieve and fill in login credentials based on the current URL. bitwarden-ruby is a replacement for bitwarden-core, a freely licensed server application with a non-free dependency (the SQL Server database).

Bleachbit

BleachBit deletes unnecessary files to free valuable disk space, maintain privacy, and remove junk. It removes cache, Internet history, temporary files, cookies, and broken shortcuts. Some common uses include:

Free disk space

Maintain privacy
Improve system performance (by vacuuming your browser's database, for example)
Prepare whole disk images for compression (common for "ghost" backups and virtual machines) by wiping free disk space

Blindsend: Modified from README.md: Blindsend is a free software tool for private, end-to-end encrypted file exchange between two agents. Current use case requires a requesting party (file Receiver) to initiate the file exchange by generating a link via blindsend and transmiting that link to the file Sender; after the Sender uploads the file to blindsend, the Receiver is able to use the same link to download the file. When exchanging files via blindsend, encryption and decryption always take place on Sender's/Receiver's local machines.

BlockSignal: BlockSignal is a secure instant messaging application based on Signal Android. Moreover, it uses a blockchain-based PKI system, Blockstack, to verify the identities of users so as to prevent Man-in-the-Middle attacks instead of Signal's authentication ceremony feature. Therefore, its security level depends on user awareness less.

BlueSpice: BlueSpice extends MediaWiki and enhances it with useful features, in particular in the areas of quality management, process support, administration, editing and security.

ClassyShark3xodus: Checks apps for code signatures of known trackers (provided by Exodus). Also can list all classes for launchable (via the app drawer) packages. Can be used against any APK: - installed: via an app manager, - downloaded: via any file manager (long press and open with ClassyShark3xodus), - launchable installed: via the first screen list (long press to list all classes, including obfuscated ones). Note: doesn't work on odexed/system packages (it's a work-in-progress). Finally, the app doesn't sync or connect to the Internet and thus cannot sneak on end users. The app is updated when Exodus updates their list of trackers: https://reports.exodus-privacy.eu.org/api/trackers ClassyShark3xodus is based on Google's ClassyShark: https://github.com/google/android-classyshark

Clipperz: Clipperz is a web based password manager. Local encryption within the browser guarantees that no one except you can read your data. With Clipperz you can quickly login to websites, as well as organize and store logins and any confidential data.

Cloudgizer: Cloudgizer is a tool for building web applications as Apache modules in C language enhanced with simple markup, with emphasis on performance, small-footprint, and more productive and safer programming in C. It combines the ease of scripting with the power of C, improving the resource utilization for cloud applications. The programmer writes simple markup language mixed with C code, which is then translated entirely into C code and compiled natively as Apache module. The resulting application is fast and takes less memory, as there are no interpreters or virtual machines. Features include easy markups to use MariaDB database, HTML input parameters, cookies, simpler outputting of web pages, files storage and manipulation, encryption, encoding, program execution, web calls, safer and easier string manipulation etc. - the list is too long to place in one sentence. Overall Cloudgizer does a lot of stuff for you that you'd otherwise need to do yourself. A memory garbage collection system and memory overwrite/underwrite detection comes in handy for program stability. The same goes for string and memory handling markups to help write applications that won't crash. Also included is an application packaging system and an automated application installer. This makes rollout of products and release cycle more manageable. Cloudgizer source files have extension .v. Cloudgizer pre-compiler (cld program) will turn your .v files into .c files, ready for compilation as pure C programs. Then, your program will be compiled and linked with Apache web server on RH/Centos systems. It links with Apache as an Apache module in a "prefork" configuration. It does the work of communicating with Apache, and it makes it easier to write high-performance/small-footprint web programs in C. Cloudgizer is not designed to be thread-safe as it works in a "prefork" configuration of Apache. You can also build command-line programs. The same program can serve as both command-line utility and a web program linked with Apache. Cloudgizer works with RedHat/Centos 7 operating system, Apache web server and mariaDB database.
