The Programming Languages Beacon
The Programming Languages Beaconv3.2 - September 2008
This table contains a list of major software products or utilities, with details about the programming languages used to implement them. Information on this is difficult to find, and a few small mistakes might have escaped the author's attention. Corrections, suggestions for additions or even references are welcome. The list is not supposed to be exhaustive but the most significant products are tentatively listed. The order of the products in each family obeys no specific rule, the reader should not understand it as a ranking.
The main programming language, the one with which most of new developments are done, is highlighted, while the ones used in older times and still present, or used only for a minority of the developments are indicated too. The pieces of software listed are usually very large, and the list of programming languages cannot be exhaustive. Miscellaneous languages are not mentioned. Sometimes, there are different products under the same line (eg "Games"), or different implementations of a single line (eg JVM implementations). In this case, the overwhelming trend is indicated. Miscellaneous counter examples are ignored.
Some readers believe that most of the applications presented are based on old code, and that the technologies in use reflect the trends of the time. As it is an erroneous belief, some introduction dates are mentioned, like here, to show that what is "new" or "old" technology does not necessarily correspond to intuition.
The difference between C and C++ is a bit artificial, as it is always possible to argue that most of C code is C++ code, or conversely (as more than a few people use C++ more or less like C). The approximation made in this document tries to correspond to intuition.
http://www.lextrait.com/vincent/green.jpg indicates the major programming language for current evolutions.
http://www.lextrait.com/vincent/empty.jpg refers to a technology which is still present, but is either stable or decreasing.
http://www.lextrait.com/vincent/red.jpg means that the product has died, and when it died, it used that technology
http://www.lextrait.com/vincent/empty_arrow_right.jpg is meant to show an evolution towards the column it points to.
When the arrow is alone, it means that the amount of code corresponding to the technology in this column is either now null or negligible, having evolved in the direction of the arrow.
The readers who might find the content of this page paradoxical will find a tentative explanation of the phenomenons at stake here. Read section 2.7.4.

(August 1997)
Corel Office, initially developed in Assembler and C, moved to Corel Office for Java, fully developed in Java for portability in 1996, and abandoned in August 1997 because it was too slow.

Cusumano book and article) redeveloped the browser using Java. It was too slow and abandoned. Mozilla, the next version, was later developed using C++. Safari7-Jan-03http://www.lextrait.com/vincent/blue_green.jpgBrowser for Apple Mac OS, its foundation is WebKit, a C++ framework. Google Chrome 2-Sept-08http://www.lextrait.com/vincent/blue_green.jpgChrome has been introduced as the combination of 26 different libraries. The base code comes from Safari . One of its key propositions is the ultra fast V8 JavaScript engine, written in C++. Sun HotJava http://www.lextrait.com/vincent/blue_red.JPG
(1999)
HotJava never took off, it was far too slow compared to other browsers. It became a showcase for the Java applet technology and the product is now frozen since 1999. Operahttp://www.lextrait.com/vincent/blue_green.jpgOpera Minihttp://www.lextrait.com/vincent/blue_green.jpghttp://www.lextrait.com/vincent/blue_green.jpgOpera Mini (2007) has a very funny architecture, and is indeed using both C++ and Java. The browser is split in two parts, an ultra thin (less than 100Kb) "viewer" client part and a server side responsible of rendering. The first uses Java and receives the page under the OBML format, the latter reuses classical Opera (C++) rendering engine plus Opera's Small Screen Rendering, on the server. This allows Opera to penetrate various J2ME-enabled portable devices, such as phones, while preserving excellent response time. This comes obviously with a few sacrifices, for instance on JavaScript execution.

(see notes)Eclipse is mostly on the market not covered by MS Visual Studio. To build it, a specific graphical toolkit was developed, SWT to replace Java classical AWT. Unlike AWT which is full Java, and judged too slow for the intensive Eclipse users, SWT is a thin Java layer on top of native C/C++ code.

(June 2007)
Motorola VIAMOTO was a smart phone "connected" GPS implementation, with a Java client-side. It was re-branded by a number of car rental companies. For instance, Avis Assist was another name for the Motorola VIAMOTO product. Avis have withdrawn this product and are now offering Garmin in the USA and TomTom in Europe. Motorola withdraws the product in June 2007. Alamo/National who had re-branded the system "Navigation Station" will also discontinue the service.This page is maintained by Vincent Lextrait (e-mail vincent@lextrait.com)
