- https://en.wikipedia.org/wiki/First-generation_programming_language - a grouping of programming languages that are machine level languages used to program first-generation computers. The instructions were given through the front panel switches of these computers, directly to the CPU. There was originally no compiler or assembler to process the instructions in 1GL.
- https://en.wikipedia.org/wiki/Second-generation_programming_language - a generational way to categorize assembly languages. The code can be read and written by a programmer. To run on a computer it must be converted into a machine readable form, a process called assembly. The language is specific to a particular processor family and environment.
- https://en.wikipedia.org/wiki/Third-generation_programming_language - a generational way to categorize high-level computer programming languages. Where assembly languages, categorized as second generation programming languages, are machine-dependent, 3GLs are much more machine independent and more programmer-friendly. This includes features like improved support for aggregate data types, and expressing concepts in a way that favors the programmer, not the computer. A third generation language improves over a second generation language by having the computer take care of non-essential details. 3GLs feature more abstraction than previous generations of languages, and thus can be considered higher level languages than their first and second generation counterparts.
First introduced in the late 1950s, Fortran, ALGOL, and COBOL are early examples of this sort of language. Most popular general-purpose languages today, such as C, C++, C#, Java, BASIC and Pascal, are also third-generation languages, although each of these languages can be further subdivided into other categories based on other contemporary traits.

- https://en.wikipedia.org/wiki/Dartmouth_BASIC - the original version of the BASIC programming language. It is so named because it was designed and implemented at Dartmouth College. The language was designed by John Kemeny and Thomas Kurtz as part of the Dartmouth Time Sharing System (DTSS) and was one of the first programming languages intended to be used interactively.
Several versions were produced at Dartmouth over the years, all implemented as compile and go compilers, unlike many of the versions of the language implemented elsewhere, which were interpreters. The first compiler was produced before the time-sharing system was ready. Known as CardBASIC, it was intended for the standard card-reader based batch processing system. Like all the following versions, it was implemented by a team of undergraduate programmers working under the direction of Kemeny and Kurtz. The first interactive version was made available to general users in June 1964; the second in October, 1964; the third in 1966; the fourth in 1969; the fifth in 1970; the sixth in 1971; and the seventh in 1979.

- Papers from the Lost Culture of Array Languages - 2012 is the 50th anniversary of Ken Iverson's A Programming Language, which described the notation that became APL (even though a machine executable version of APL didn't exist yet). Since then there's been APL2, Nial, A+, K, Q, and other array-oriented languages. Iverson (1920-2004) teamed with Roger Hui to create a modern successor to APL, tersely named J, in the late 1980s. The culture of array languages is a curious one. Though largely functional, array languages represent a separate evolutionary timeline from the lambda calculus languages like Miranda and Haskell.

The technology makes it easy to create deeply collaborative and hyperlinked multi-user virtual workspaces, virtual exhibit spaces, and game-based learning and training environments that run on all major software operating systems. By using a peer-based messaging protocol to reduce reliance on server infrastructures for support of basic in world interactions across many participants, Open Cobalt makes it possible for people to hyperlink their virtual worlds via 3D portals to form a large distributed network of interconnected collaboration spaces. It also makes it possible for schools and other organizations to freely set up their own networks of public and private 3D virtual workspaces that feature integrated web browsing, voice chat, text chat and access to remote desktop applications and services.
- TypeTalk - an attempt to replicate the classic SmallTalk/Lisp paradigm which don’t distinguish between users and programmers: you can, if you wish, take the lid off the application suite you’re currently using and tinker with it, without recompilation, restarts, or even having to save your work.Currently it’s a pile of fairly nasty hacks flying in loose formation, but it does actually work. Mostly.

Generic Objective-C programs that do not use the Cocoa or Cocoa Touch libraries can also be compiled for any system supported by GCC or Clang.
Caml / OCaml
- http://en.wikipedia.org/wiki/OCaml - originally known as Objective Caml, is the main implementation of the Caml programming language, created by Xavier Leroy, Jérôme Vouillon, Damien Doligez, Didier Rémy, Ascánder Suárez and others in 1996. OCaml extends the core Caml language with object-oriented constructs. OCaml's toolset includes an interactive top level interpreter, a bytecode compiler, a reversible debugger, a package manager (OPAM), and an optimizing native code compiler. It has a large standard library that makes it useful for many of the same applications as Python or Perl, as well as robust modular and object-oriented programming constructs that make it applicable for large-scale software engineering. OCaml is the successor to Caml Light. The acronym CAML originally stood for Categorical Abstract Machine Language, although OCaml abandons this abstract machine. OCaml is a free open source project managed and principally maintained by INRIA. In recent years, many new languages have drawn elements from OCaml, most notably F# and Scala.

A package is a library of Haskell modules known to the compiler. GHC comes with several packages: see the accompanying library documentation. More packages to install can be obtained from HackageDB.
Using a package couldn't be simpler: if you're using ––make or GHCi, then most of the installed packages will be automatically available to your program without any further options. The exceptions to this rule are covered below in Section 4.9.1, “Using Packages ”.
Building your own packages is also quite straightforward: we provide the Cabal infrastructure which automates the process of configuring, building, installing and distributing a package. All you need to do is write a simple configuration file, put a few files in the right places, and you have a package. See the Cabal documentation for details, and also the Cabal libraries (Distribution.Simple, for example).
- Cabal (Common Architecture for Building Applications and Libraries) is a system for building and packaging Haskell libraries and programs. It defines a common interface for package authors and distributors to easily build their applications in a portable way. Cabal is part of a larger infrastructure for distributing, organizing, and cataloging Haskell libraries and programs. Specifically, the Cabal describes what a Haskell package is, how these packages interact with the language, and what Haskell implementations must to do to support packages. The Cabal also specifies some infrastructure (code) that makes it easy for tool authors to build and distribute conforming packages.
- HackageDB (or just Hackage) is a collection of releases of Haskell packages. Each package is in the Cabal format, a standard way of packaging Haskell source code that makes it easy to build and install. These pages are a basic web interface to the Hackage package database.
- cabal-install package provides the cabal command-line tool which simplifies the process of managing Haskell software by automating the fetching, configuration, compilation and installation of Haskell libraries and programs. Those packages must be prepared using Cabal and should be present at Hackage.

- Elixir is a functional meta-programming aware language built on top of the Erlang VM. It is a dynamic language with flexible syntax with macros support that leverages Erlang's abilities to build concurrent, distributed, fault-tolerant applications with hot code upgrades. Elixir also provides first-class support for pattern matching, polymorphism via protocols (similar to Clojure's), aliases and associative data structures (usually known as dicts or hashes in other programming languages). Finally, Elixir and Erlang share the same bytecode and data types. This means you can invoke Erlang code from Elixir (and vice-versa) without any conversion or performance hit. This allows a developer to mix the expressiveness of Elixir with the robustness and performance of Erlang.
From Microsoft, compiles to JS.
- Idris - Idris is a general purpose pure functional programming language with dependent types. Dependent types allow types to be predicated on values, meaning that some aspects of a program’s behaviour can be specified precisely in the type. It is compiled, with eager evaluation.

- Gravity Documentation - a powerful, dynamically typed, lightweight, embeddable programming language written in C without any external dependencies (except for stdlib). It is a class-based concurrent scripting language with a modern Swift like syntax. Gravity supports procedural programming, object-oriented programming, functional programming and data-driven programming. Thanks to special built-in methods, it can also be used as a prototype-based programming language. Gravity has been developed from scratch for the Creo project in order to offer an easy way to write portable code for the iOS and Android platforms. It is written in portable C code that can be compiled on any platform using a C99 compiler. The VM code is about 2K lines long, the multipass compiler code is about 3K lines and the shared code is about 2K lines long. The compiler and virtual machine combined add less than 200KB to the executable on a 64 bit system. 
- WysiScript - Programming via direct syntax highlighting. The efficiency of programming is often hampered by the need to type the right text in order to obtain the syntax highlighting that will produce the desired program behavior. The programmer can control the colors and formatting of the code only indirectly, through arcane textual incantations. In this paper we introduce WysiScript, a new language which frees the programmer from this antiquated dependence on text by allowing program semantics to be expressed through direct application of colors and formatting. We give a description of the main ideas of the language and demonstrate its power and ease of use with some example programs. We end by proposing a novel technique for understanding the structure of a program, which is made possible only by the fresh approach taken by WysiScript.
