Lingerd: Lingerd is a daemon designed to properly close network connections from an HTTP server (ie Apache). This frees the server from doing the boring but time-consuming job of "lingering closes", and lets each process go on to the next connection immediately. As a result, Apache needs fewer processes to handle high loads. This saves memory, reduces kernel contention, and makes Apache more scalable.

LiquidFeedback: LiquidFeedback is an open-source software, powering internet platforms for surveys, proposition development and decision making. LiquidFeedback is an independent open source project. The software is published under MIT license by the Public Software Group of Berlin, Germany. The developers of LiquidFeedback have teamed up in the Association for Interactive Democracy to promote the use of electronic media for democratic processes.

Luma: 'Luma' is a graphical utility for accessing and managing data stored on LDAP servers. It is written in Python using PyQt and python-ldap. It features support for plugins and supports English, German, Portuguese, and Norwegian.

MC: MC is a C++ program that creates vector-space models from text documents that can be used for text mining applications. MC provides an efficient multi-threaded implementation that can process very large document collections. The MC program: 1. Recursively descends directories, finding text files 2. Processes files selectively through full regular expression matching of file names. 3. Builds a sparse matrix of word/token counts. The particular sprse marix format used is given here. 4. Processes any user specified text formats(email address or URLs) as a whole token through regular expression matching or FLEX definition. 5. Prunes vocabulary by word length and frequency 6. Excludes user specified stop words 7. Sets word vector weights according any of the txx, txn, tfn, tfx, lxx, lxn, lfn, lfx scaling schemes. 8. Writes all data structures to disk in the Compressed Column Storage format. The application does not have English parsing or part-of-speech tagging facilities or complete documentation

MESICON: Free software to assist in cataloguing challenging items in museum libraries (for example).

Mail2web: mail2web makes a mail archive, organised as RFC 5322 files in directories, accessible by HTTP.

Mailfront: 'mailfront' is a set of customizeable network protocol frontends for mail servers, replacing or supplementing the features available with the MTA software. It contains complete SMTP, QMQP, QMTP, and POP3 front-ends as well as an authentication module for IMAP. The mail delivery front-ends also contain internal address filtering features. Two SMTP back-ends are provided. One delivers mail to qmail-queue, mimicking most of the behavior of qmail-smtpd, with the addition of support for SMTP AUTH. The other rejects all SMTP commands if $SMTPREJECT is set, and execs its command line otherwise (in order to run the above program).

Mandos: The Mandos system allows computers to have encrypted root file systems and at the same time be capable of remote and/or unattended reboots. WouldnÃ¢â¬â¢t it be great if you could have the security of encrypted root file systems and still have servers that could boot up automatically if there was a short power outage while you were asleep? That you could reboot at will, without having someone run over to the server to type in the password? Well, with Mandos, you (almost) can! The gain in convenience will only be offset by a small loss in security. The setup is as follows: The server will still have its encrypted root file system. The password to this file system will be stored on another computer (henceforth known as the Mandos server) on the same local network. The password will *not* be stored in plaintext, but encrypted with OpenPGP. To decrypt this password, a key is needed. This key (the Mandos client key) will not be stored there, but back on the original server (henceforth known as the Mandos client) in the initial RAM disk image. Oh, and all network Mandos client/server communications will be encrypted, using TLS (SSL).

MaraDNS: 'MaraDNS' is a fully functional DNS server supporting authoritative DNS, recursive DNS, and caching DNS. It is intended for environments where a DNS server must be secure and where the server must use the absolute minimum number of resources possible. Its security features include the use of a special string library which is resistant to buffer overflows and that the code, if started as root, mandates running as an unpriviledged user in a chroot() jail.

MariaDB: MariaDB is a multi-user and multi-threaded SQL database server, designed as a drop-in replacement of MySQL. It includes all major free storage engines, including the Aria storage engine.

Mautic: Mautic is an open source marketing automation platform that provides you with the greatest level of audience intelligence, thus enabling you to make more meaningful customer connections. Use Mautic to engage your customers and create an efficient marketing strategy.

Metahtml: MetaHTML is a server-side programming language designed for the World Wide Web. It has a syntax that is similar to HTML and Lisp. It provides a large function library, including support for sockets, image creation and connections to other programs.

Metakit: 'Metakit' fills the gap between flat-file, relational, object-oriented, and tree-structured databases, supporting relational joins, serialization, nested structures, and instant schema evolution. There is a C++ API, a Python binding (Mk4py), and a Tcl binding (Mk4tcl). Data files are portable, use auto-sizing ints and strings, and can efficiently store binary data from single bits to multi-Mb objects. MetaKit works well for moderate-size (a few dozen Mb) datasets, and offers excellent performance well beyond that size when its column-wise data model is fully taken advantage of.

MiddleMan: MiddleMan is a fast HTTP/HTTPS proxy server that removes unwanted content and increases privacy. It uses an XML configuration file, and fully implements the HTTP 1.1 protocol, including persistent proxy connections. It has file, host, cookie, header, and content filtering, and can forward through both socks4 and regular http/https proxies.

MinIO: High Performance Storage

Mod python: Mod_python is an Apache module that embeds the Python language interpreter within the server. This lets Apache handlers be written in Python for faster and more powerful applications than plain CGI.

Mod security: 'Mod_security' is an intrusion detection and prevention module for Apache Web servers. Its purpose is to protect vulnerable applications by detecting and (optionally) rejecting attacks. In addition to request filtering (using regex), it can create Web application audit logs. Unlike other similar projects, Mod_security can analyse POST payloads.

MonetDB: MonetDB is a database management system developed from a main-memory perspective using a fully decomposed storage model, automatic index management, extensibility of data types and search accelerators, and SQL- and XML- frontends. It was designed to provide high performance on complex queries against large databases, e.g. combining tables with hundreds of columns and multi-million rows. Because of this, MonetDB can be used in application areas that have in the past been too slow for using traditional database technology in real-time.

Mongo Engine: MongoEngine is a Python Object-Document Mapper for working with MongoDB. Documentation available at http://hmarr.com/mongoengine/ - there is currently a tutorial, a user guide and an API reference.

MongoDB

In Oct 2018, MongoDB's "community edition" switched from AGPLv3 to another license making it harder for free software users to depend on it. The source linked in this entry is the last available code base under the AGPLv3. See FerretDB for an alternative. MongoDB (from "humongous") is a scalable, high-performance, schema-free, document-oriented database. Features:

Document-oriented storage (the simplicity and power of JSON-like data schemas)
Dynamic queries
Full index support, extending to inner-objects and embedded arrays
Query profiling
Fast, in-place updates
Efficient storage of binary data large objects (e.g. photos and videos)
Replication and fail-over support

Monkey HHTP Daemon: Monkey HTTP Daemon is a small, fast Web server. It is based on the HTTP 1.1 protocol. Features include language support, GET, POST, and HEAD methods, CGI, PHP4, a config file (optional for every user), a mime.types file, virtual hosts, the ability to deny URLs and IPs, to run as a different user (such as nobody), serve users home directories, and more.

Mumblr: Mumblr is a simple Tumblelog application, written in Django. It uses MongoDB as its database, and MongoEngine for communicating with MongoDB from Django.

My SQL Navigator: MySQL Navigator is MySQL database server GUI client program. The purpose of MySQL Navigator is to provide a useful client interface to MySQL database servers, while supporting multiple operating systems and languages. You can currently enter queries, get result sets, edit scripts, run scripts, add, alter, and delete users, and retrieve client and server infomation.

My2pg: 'my2pg' converts MySQL 3.22 and 3.23 dumps into Postgres dumps. It emulates ENUMs and SETs via user types and operators. It is intended for PostgreSQL users who want to migrate from MySQL. It is included in the contributed tree of the PostgreSQL distribution.

MyBkp 2: This is a candidate for deletion: 1. No files sources found. This is a Korn shell script for performing various backup and recovery related tasks of MySQL. This tool can be used for various purposes including various kinds of backups (Dump, Cold, Hot, Snapshot), restoration of backups in a database, verifying the backups (checksum), set Retention policy for backups, generating reports of backups taken and their status, scheduling Jobs for backups and report generation, and doing Point-in-time recovery.

MyClient: MyClient is a Web client interface for the MySQL database. Features include multiple query windows, one-button table descriptions, one button database switching, query save and load, and query results saving. It is not a full featured administration tool, but a quick and easy query interface for users who want a Web-based implementation of the command line interface.

MyDNS: MyDNS is a free DNS server for *nix. It was implemented from scratch and is designed to serve records directly from an SQL database (currently either MySQL or PostgreSQL). Its primary objectives are stability, security, interoperability, and speed, though not necessarily in that order. MyDNS does not include recursive name service, nor a resolver library. It is primarily designed for organizations with many zones and/or resource records who desire the ability to perform real-time dynamic updates on their DNS data via MySQL.

MySQL: MySQL is a fast, reliable, and easy to use relational database management system that supports the standardized Structured Query Language.

MySQL Backup: MySQL Backup is a Perl script that uses mysqlshow to grab the database names and "show tables" to grab the table names for a user's account, and then uses mysqldump to save the data in a subdirectory named in the script. It then tars and gzips the files, using the date and time for the file name. It can be run from cron on a daily basis. It removes old files and has an option to email the gzip file to an admin and/or FTP the backup file to a remote server. It also has options to use "select data into outfile" or a regular "select" for users who can't use mysqldump. It supports LARGE sets of databases and tables (GNU/Linux utilities such as tar, ls and nice break when the argument list gets too long). To do this, the script places all the sql text files in a subdirectory and tars the directory. For security, if a .my.cnf file is used then mysqlshow and mysqldump run without the --user and --password parameters, so the password doesn't display in the process list.

MySQL for Python (MySQLdb)

MySQLdb is an interface to the popular MySQL database server for Python. The design goals are:

Compliance with Python database API version 2.0 [PEP-0249]
Thread-safety
Thread-friendliness (threads will not block each other)
MySQL-3.23 through 5.0 and Python-2.3 through 2.6 are currently supported. Python-3.0 will be supported in a future release.

MySQL-to-CSV: MySQL-to-CSV is a free program to convert MySQL databases into comma separated values (CSV) files. The program has high performance due to direct connection to source databases and writing into .csv files (it does not use ODBC or any other middleware software). Command line support allows to script, automate and schedule the conversion process.

Myserver: MyServer is a powerful web server designed to be easily run on a personal computer by the average computer user. It is a multithread application and supports HTTP, HTTPS, CGI, ISAPI, WinCGI and FastCGI protocols. You can share files in minutes.

Mysql client: 'mysql_client' is a MySQL database GUI client program. The purpose of MySQL Perl/CGI Client is to provide a useful and flexible client interface for MySQL database servers. It can support multiple operating systems and languages.

NextTypes: NextTypes is a standards based information storage, processing and transmission system that integrates the characteristics of other systems such as databases, programming languages, communication protocols, file systems, document managers, operating systems, frameworks, file formats and hardware in a single tightly integrated system using a common data types system. NextTypes is a relational/network/objects/files hybrid database system with high level SQL interface, extensive primitive types list, JSON/JSON-LD/XML/Smile/WebDAV/CalDAV/iCalendar/RSS data access, REST interface, customizable MVC architecture, optimistic concurrency control, HTML5/CSS3/SVG/Javascript responsive graphical interface, multilanguage, UTF-8 encoding, syntax highlighting or WYSIWYG editors, robots.txt and sitemap management, text extraction/fulltext search, document management, virus scanning, DoS/SQL injection/CSRF/XSS protection, passwords/X.509 certificates authentication, logging and backup system.

NoSQL: NoSQL is a fast, portable relational database management system without arbitrary limits (other than memory or processor speed) that runs under, and interacts with, the UNIX Operating system. It uses the Operator/Stream DBNS paradigm described in "UNIX Review," March 1991 Page 24, entitled "A 4GL Language." There are a number of 'operators' that each perform a unique function on the data. The "stream" is supplied by the UNIX Input/Output redirection mechanism. Therefore, each operator p[rocesses some data and then passes it along to the next operator via the Unix pipe function. This is very efficient as UNIX pipes are implemented in memory.

NocoDB: NocoDB turns any MySQL, PostgreSQL, SQLite database into a spreadsheet with REST APIs. It supports basic and fields operations, multiple view types, different permissions, sharing, variant cell types, access control with roles, and others.

ODOP:Spring: More than a spring calculator, ODOP:Spring is full-featured spring design software for engineering custom helical coil springs, including compression, torsion and extension springs. While certainly capable of analyzing the performance of an existing spring design, our open-source and free to use web app is at its best when used to develop solutions to difficult and highly constrained original design problems. Typical spring calculators perform design analysis, requiring users to make repeated inputs (independent variables of the design equations like wire diameter, coil diameter, number of coils and loads) until the desired outputs (dependent variables like deflections, stresses, weight, and estimated cycle life) are achieved. On the other hand, ODOP:Spring performs design synthesis to invert the dependent / independent relationships of the design equations and perform constrained optimization. You input specific goals, and ODOP:Spring returns the variable values that best meet those goals.

Odoo: Odoo (previously OpenERP) is a suite of programs that help companies to grow their business. Over 2 million people use Odoo to grow their sales, run their operations, organize marketing activities, boost productivity and empower their human resources. Odoo is used worldwide and provides complete software solution from front office to back office.

OneModel: Today: You can take notes with it. Rearrange them easily, up and down in a list, or up/down in the hierarchy. Link them to each other. Navigate across links with simple keypresses. Make deeply nested lists. Link lists to lists. Compose long paragraphs and attach them. Or do more complicated things if desired, by creating relationship types and using those. Import txt or export txt or html. It's better than the alternatives for some people, because the navigation takes fewer keystrokes, you don't have to read a manual (it's all on the screen, or so I like to think), you can have the same thing in as many places as you want, it is Free (some alternatives are, others are not), and it has immense future potential for becoming a better-structured, much more powerful and flexible wikipedia-like tool, if we work together. Vision: The idea is to have the most efficient personal knowledge organizer (now available in a usable text-based interface), then support mobile access, easy internal automation, and effective sharing and collaboration. Then, to combine efforts and learn as we go until we integrate humankind's knowledge over time. The key differentiators are that it is to be Free, and based on an object model (easily created on the fly as a side-effect of using the system), rather than on massive amounts of words. The knowledge is the same, even if the words can change. One can think of that as "using building blocks of knowledge, starting at an atomic level (i.e. numbers, relationships...), free and efficient." Or, taking the best experiences of online organizer tools and wikis, but more structured, efficient, Free, open, and collaborative; and allowing full individual or organizational control.

OpenCart: OpenCart is a free ecommerce platform for online merchants. OpenCart provides a professional and reliable foundation from which to build a successful online store.

OpenFTS: OpenFTS (Open Source Full Text Search engine) is an advanced PostgreSQL-based search engine that provides online indexing of data and relevance ranking for database searching. Close integration with database allows use of metadata to restrict search results.

OpenInteract: 'OpenInteract' is an extensible Web application server that includes a robust system of components, object-oriented data access, a consistent security scheme for both tasks and data objects, a simple user and group management system, and a packaging system that makes it easy to distribute custom applications. It is stable, and runs out of the box on five different databases.

Openbarter: openBarter extends the mechanism of a CLOB - the central part of regular markets - and implements a multilateral barter. It is based on an extension of PostgreSQL.

Openstreetmap-website: OpenStreetMap is a project for creating and distributing free geographic data for the world.

Orthanc: Orthanc aims at providing a simple, yet powerful standalone DICOM server. It is designed to improve the DICOM flows in hospitals and to support research about the automated analysis of medical images. Orthanc can turn any computer running Windows or GNU/Linux into a DICOM store (in other words, a mini-PACS system). Its architecture is lightweight and standalone, meaning that no complex database administration is required, nor the installation of third-party dependencies. What makes Orthanc unique is the fact that it provides a RESTful API. Thanks to this major feature, it is possible to drive Orthanc from any computer language. The DICOM tags of the stored medical images can be downloaded in the JSON file format. Furthermore, standard PNG images can be generated on-the-fly from the DICOM instances by Orthanc. Orthanc lets its users focus on the content of the DICOM files, hiding the complexity of the DICOM format and of the DICOM protocol.

Osticket: osTicket is a widely-used free software support ticket system. It seamlessly integrates inquiries created via email, phone and web-based forms into a simple easy-to-use multi-user web interface. Manage, organize and archive all your support requests and responses in one place while providing your customers with accountability and responsiveness they deserve.

OurSQL

oursql is a new set of mysql bindings for python 2.4+. HereÃ¢â¬â¢s a short list of reasons why you should use oursql over MySQLdb:

oursql has real parameterization.
oursql allows text or binary data to be streamed into the database and streamed out of the database, instead of requiring everything to be buffered in the client.
oursql can both insert rows lazily and fetch rows lazily.
oursql has unicode support on by default.

OxideDB: OxideDB is a translation layer that works as a MongoDB database server while using PostgreSQL's JSON capabilities as the underlying data store.

PDO: Python Database Objects: PDO: Python Database Objects, is a collection of objects for use with Phase or with the Python Programing Language. PDO is designed to be robust and simple at the same time, allowing access to multiple styles of databases, with one set of instructions. This means never having to worry again about your syntax when changing Database Platforms on your next project.
