94-397: Inferno was created in 1995 by members of Bell Labs ' Computer Science Research division to bring ideas derived from their previous operating system, Plan 9 from Bell Labs , to a wider range of devices and networks. Inferno is a distributed operating system based on three basic principles: To handle the diversity of network environments it was intended to be used in, the designers decided

188-436: A just-in-time compiler for new architectures. The virtual machine provides memory management designed to be efficient on devices with as little as 1 MiB of memory and without memory-mapping hardware. Its garbage collector is a hybrid of reference counting and a real-time coloring collector that gathers cyclic data. The Inferno kernel contains the virtual machine, on-the-fly compiler, scheduler, devices, protocol stacks, and

282-454: A plugin to Internet Explorer . Vita Nuova said that plugins for other browsers were under development, but they were never released. Inferno has also been ported to Openmoko , Nintendo DS , SheevaPlug , and Android . Inferno 4th edition was released in early 2005 as free software . Specifically, it was dual-licensed under two structures. Users could either obtain it under a set of free software licenses , or they could obtain it under

376-501: A virtual machine (VM) was a necessary component of the system. This is the same conclusion of the Oak project that became Java , but arrived at independently. The Dis virtual machine is a register machine intended to closely match the architecture it runs on, in contrast to the stack machine of the Java virtual machine . An advantage of this approach is the relative simplicity of creating

470-465: A 20% stake in Sun. UNIX System V Release 4 (SVR4) was jointly developed by AT&T and Sun. Sun used SVR4 as the foundation for Solaris 2.x, which became the successor to SunOS 4.1.x (later retroactively named Solaris 1.x). By the mid-1990s, the ensuing Unix wars had largely subsided, AT&T had sold off their Unix interests, and the relationship between the two companies was significantly reduced. In

564-599: A Bell subsidiary, the Engineering Department was reformed into Bell Telephone Laboratories in 1925 and placed under the shared ownership of Western Electric and the American Telephone and Telegraph Company (AT&T). In the 1960s, laboratory and company headquarters were moved to Murray Hill, New Jersey . Its alumni during this time include people like William Shockley , Dennis Ritchie , Claude Shannon and Willard Boyle . Bell Labs became

It was the first CoolThreads CPU with multi-processor capability and it made possible to build standard rack-mounted servers that could simultaneously process up to massive 256 CPU threads in hardware (Sun SPARC Enterprise T5440), which is considered a record in the industry. Since 2010, all further development of Sun machines based on SPARC architecture (including new SPARC T-Series servers, SPARC T3 and T4 chips)

1880-604: Is an increasing need to reduce power and air conditioning demands, much of which comes from the heat generated by CPUs. The T1 was followed in 2007 by the UltraSPARC T2 , which extended the number of threads per core from 4 to 8. Sun has open sourced the design specifications of both the T1 and T2 processors via the OpenSPARC project. In 2006, Sun ventured into the blade server (high density rack-mounted systems) market with

1974-509: Is done as a part of Oracle Corporation hardware division. In the late 1980s, Sun also marketed an Intel 80386 –based machine, the Sun386i ; this was designed to be a hybrid system, running SunOS but at the same time supporting DOS applications. This only remained on the market for a brief time. A follow-up "486i" upgrade was announced but only a few prototype units were ever manufactured. Sun's brief first foray into x86 systems ended in

3008-582: The dot-com bubble , Sun began making more money, with its stock rising as high as $ 250 per share. It also began spending much more, hiring workers and building itself out. Some of this was because of genuine demand, but much was from web start-up companies anticipating business that would never happen. In 2000, the bubble burst. Sales in Sun's important hardware division went into free-fall as customers closed shop and auctioned high-end servers. Several quarters of steep losses led to executive departures, rounds of layoffs, and other cost cutting. In December 2001,

3102-402: The thermal noise in a resistor was first measured by John B. Johnson , for which Harry Nyquist provided the theoretical analysis; this is now termed Johnson-Nyquist noise . During the 1920s, the one-time pad cipher was invented by Gilbert Vernam and Joseph Mauborgne at the laboratories. Bell Labs' Claude Shannon later proved that it is unbreakable.

4418-596: The aim of building network appliances (single function computers meant for consumers). Sun also marketed a Network Computer (a term popularized and eventually trademarked by Oracle ); the JavaStation was a diskless system designed to run Java applications. Although none of these business initiatives were particularly successful, the Cobalt purchase gave Sun a toehold for its return to the x86 hardware market. In 2002, Sun introduced its first general purpose x86 system,

4512-576: The amounts indicated when the acquisition closed. For the first decade of Sun's history, the company positioned its products as technical workstations , competing successfully as a low-cost vendor during the Workstation Wars of the 1980s. It then shifted its hardware product line to emphasize servers and storage. High-level telecom control systems such as Operational Support Systems service predominantly used Sun equipment. Sun originally used Motorola 68000 family central processing units for

Its intent was to drive more efficient use of CPU resources, which is of particular importance in data centers , where there

6486-527: The name space evaluator for each process' file name space, and the root of the file system hierarchy. The kernel also includes some built-in modules that provide interfaces of the virtual operating system, such as system calls, graphics, security, and math modules. The Bell Labs Technical Journal paper introducing Inferno listed several dimensions of portability and versatility provided by the OS: These design choices were directed to provide standard interfaces that free content and service providers from concern of

6580-433: The negative feedback system commonly used in amplifiers. Later, Harry Nyquist analyzed Black's design rule for negative feedback. This work was published in 1932 and became known as the Nyquist criterion . In 1931, a foundation for radio astronomy was laid by Karl Jansky during his work investigating the origins of static on long-distance shortwave communications . He discovered that radio waves were being emitted from

6674-632: The new UltraSPARC CPUs based on the SPARC V9 architecture. Within the next four years, the successors Solaris 8 and Solaris 9 were released in 2000 and 2002 respectively. Following several years of difficult competition and loss of server market share to competitors' Linux-based systems, Sun began to include Linux as part of its strategy in 2002. Sun supported both Red Hat Enterprise Linux and SUSE Linux Enterprise Server on its x64 systems; companies such as Canonical Ltd. , Wind River Systems and MontaVista also supported their versions of Linux on Sun's SPARC-based systems. In 2004, after having cultivated

6768-568: The one in Gulfport. The three test plots at Gulfport, Limon, and Chester were outdoor facilities for preservatives and prolonging the use of telephone poles. Additionally, in 1929, a land expansion was done at the Deal Labs to 208 acres (84 ha). This added land increased the facility for radio transmission studies. The beginning of 1930s, established three facilities with radio communications experiments and chemical aspects testing. By 1939,

6862-464: The only computers other than DEC 's VAX to run 4.2BSD . It licensed the computer design to other manufacturers, which typically used it to build Multibus -based systems running Unix from UniSoft . Sun's initial public offering was in 1986 under the stock symbol SUNW , for Sun Workstations (later Sun Worldwide ). The symbol was changed in 2007 to JAVA ; Sun stated that the brand awareness associated with its Java platform better represented

6956-509: The result was not published until 1950. In 1948, " A Mathematical Theory of Communication ", one of the founding works in information theory , was published by Claude Shannon in the Bell System Technical Journal . It built in part on earlier work in the field by Bell researchers Harry Nyquist and Ralph Hartley , but went much further. Bell Labs also introduced a series of increasingly complex calculators through

7050-451: The same interfaces whether Inferno runs natively on hardware or runs as a user program on top of another operating system. A communications protocol called Styx is applied uniformly to access both local and remote resources, which programs use by calling standard file operations, open, read, write, and close. As of the fourth edition of Inferno, Styx is identical to Plan 9 's newer version of its hallmark 9P protocol, 9P2000 . Most of

7144-402: The stock fell to the 1998, pre-bubble level of about $ 100. It continued to fall, faster than many other technology companies. A year later, it had reached below $ 10 (a tenth of what it was in 1990), but it eventually bounced back to $ 20. In mid-2004, Sun closed their Newark, California , factory and consolidated all manufacturing to Hillsboro, Oregon and Linlithgow, Scotland. In 2006, the rest of

7238-464: The success of the newly named Bell Works site, but several large tenants had announced plans to move in through 2016 and 2017. Bell Lab's 1974 corporate directory listed 22 labs in the United States, located in: Nokia Bell Lab's 2024 website pictured 10 labs, located in: Also listed as research locations without additional information was Sunnyvale, California , US and Tampere, Finland . The Naperville, Illinois Bell Labs location near Chicago

7332-569: The test plot studies were established at Gulfport, Mississippi , where there were numerous telephone pole samples established for wood preservation. At the Deal, New Jersey location, work was done on ship-to-shore radio telephony. In 1926, in the Whippany section of Hanover Township, New Jersey , land was acquired and established for the development of a 50-kilowatt broadcast transmitter. In 1931, Whippany increased with 75 acres (30 ha) added from

7426-547: The time the company was acquired by Oracle Corporation , it had outsourced most manufacturing responsibilities. On April 20, 2009, it was announced that Oracle would acquire Sun for US$ 7.4 billion. The deal was completed on January 27, 2010. The initial design for what became Sun's first Unix workstation , the Sun-1 , was conceived by Andy Bechtolsheim when he was a graduate student at Stanford University in Palo Alto , California. Bechtolsheim originally designed

7520-736: The time, having contributed the vi editor, the C shell , and significant work developing TCP/IP and the BSD Unix OS. Sun later developed software such as the Java programming language and acquired software such as StarOffice , VirtualBox and MySQL . In February 1991, the company established SunSoft, Inc., a wholly owned division of Sun dedicated to the development of operating systems and application software. Sun used community-based and open-source licensing of its major technologies, and for its support of its products with other open source technologies. GNOME -based desktop software called Java Desktop System (originally code-named "Madhatter")

7614-470: The vacuum tube designs of the times. The device could be installed in a B-52 Stratofortress Bomber and had a performance up to one million logical operations a second. The flyable program used a Mylar sheet with punched holes, instead of the removable plugboard. In 1954, the first modern solar cell was invented at Bell Laboratories. In 1955, Carl Frosch and Lincoln Derick discovered semiconductor surface passivation by silicon dioxide. In 1956 TAT-1 ,

7708-519: Was a popular Unix variant for the PC platform and a major competitor to market leader SCO UNIX . Sun's focus on Interactive Unix diminished in favor of Solaris on both SPARC and x86 systems; it was dropped as a product in 2001. Sun dropped the Solaris 2.x version numbering scheme after the Solaris 2.6 release (1997); the following version was branded Solaris 7. This was the first 64-bit release, intended for

7802-635: Was accelerated by the acquisition of Cray Business Systems Division from Silicon Graphics. Their 32-bit, 64-processor Cray Superserver 6400 , related to the SPARCcenter, led to the 64-bit Sun Enterprise 10000 high-end server (otherwise known as Starfire or E10K). In September 2004, Sun made available systems with UltraSPARC IV which was the first multi-core SPARC processor. It was followed by UltraSPARC IV+ in September 2005 and its revisions with higher clock speeds in 2007. These CPUs were used in

7896-506: Was considered the Chicago Innovation Center and hosted Nokia's second annual Algorithm World event in 2022. Bell Laboratories was, and is, regarded by many as the premier research facility of its type, developing a wide range of revolutionary technologies, including radio astronomy , the transistor , the laser , information theory , the operating system Unix , the programming languages C and C++ , solar cells ,

7990-523: Was distributed for the Solaris operating system, and at one point for Linux. Sun supported its Java Enterprise System (a middleware stack) on Linux. It released the source code for Solaris under the open-source Common Development and Distribution License , via the OpenSolaris community. Sun's positioning includes a commitment to indemnify users of some software from intellectual property disputes concerning that software. It offers support services on

8084-438: Was doing research into the service providers. In 1896, Western Electric bought property at 463 West Street to centralize the manufacturers and engineers which had been supplying AT&T with such technology as telephones, telephone exchange switches and transmission equipment. During the early 20th century, several historically significant laboratories were established. In 1915, the first radio transmissions were made from

8178-506: Was ending its operations as Holmdel was established. Whereas, in 1930, a location in Mendham Township, New Jersey , was established to continue radio receiver developments farther from the Whippany location and eliminate transmitter interference at that facility with developments. The Mendham location worked on communication equipment and broadcast receivers. These devices were used for marine, aircraft, and police services as well as

8272-581: Was founded on February 24, 1982. At its height, the Sun headquarters were in Santa Clara, California (part of Silicon Valley ), on the former west campus of the Agnews Developmental Center . Sun products included computer servers and workstations built on its own RISC -based SPARC processor architecture , as well as on x86 -based AMD Opteron and Intel Xeon processors. Sun also developed its own storage systems and

8366-779: Was in turn acquired by Nokia in 2016. In 1880, when the French government awarded Alexander Graham Bell the Volta Prize of 50,000   francs for the invention of the telephone (equivalent to about US$ 10,000 at the time, or about $ 330,000 now), he used the award to fund the Volta Laboratory (also known as the "Alexander Graham Bell Laboratory") in Washington, D.C. in collaboration with Sumner Tainter and Bell's cousin Chichester Bell . The laboratory

8460-460: Was instrumental in advancing Army and Navy ammunition acceptance and material sampling procedures. In 1947, the transistor , arguably the most important invention developed by Bell Laboratories, was invented by John Bardeen , Walter Houser Brattain , and William Bradford Shockley (who subsequently shared the Nobel Prize in Physics in 1956). In 1947, Richard Hamming invented Hamming codes for error detection and correction . For patent reasons,

8554-420: Was organized to consolidate the development and research activities in the communication field and allied sciences for the Bell System. Ownership was evenly shared between Western Electric and AT&T. The new company had 3600 engineers, scientists, and support staff. Its 400,000-square-foot (37,000 m ) space was expanded with a new building occupying about one quarter of a city block. The first chairman of

8648-427: Was the origin of the modern quality control movement, including Six Sigma . In 1926, the laboratories invented an early synchronous-sound motion picture system, in competition with Fox Movietone and DeForest Phonofilm . In 1927, a Bell team headed by Herbert E. Ives successfully transmitted long-distance 128-line television images of Secretary of Commerce Herbert Hoover from Washington to New York. In 1928

8742-667: Was variously known as the Volta Bureau , the Bell Carriage House , the Bell Laboratory and the Volta Laboratory . It focused on the analysis, recording, and transmission of sound. Bell used his considerable profits from the laboratory for further research and education advancing the diffusion of knowledge relating to the deaf. This resulted in the founding of the Volta Bureau ( c.  1887 ) at

8836-475: Was written to facilitate that. However, Inferno still did not find customers. The Inferno Business Unit closed after three years, and was sold to Vita Nuova Holdings. Vita Nuova continued development and offered commercial licenses to the complete system, and free downloads and licenses (not GPL compatible) for all of the system except the kernel and VM. They ported the software to new hardware and focused on distributed applications. Eventually, Vita Nuova released
