Richard Ferris Rashid served as a VP at Microsoft for many years. He oversaw Microsoft Research's worldwide operations until 2012. Previously, he was the director of Microsoft Research. He joined Microsoft Research in 1991, and was promoted to vice president in 1994. In 2000, he became senior vice president. He has authored a number of patents in areas such as data compression, networking, and operating systems, and was a major developer of Microsoft's interactive TV system.
Rashid graduated from Stanford University in 1974 with degrees in mathematics and comparative literature. He then received a Master of Science and a Ph.D. in computer science from the University of Rochester, finishing in 1980. While at Rochester, he and Gene Ball wrote what is probably one of the earliest networked multiplayer computer games, Alto Trek, for Xerox Alto computers.
In 1979, he became a professor of computer science at Carnegie Mellon University. While a faculty member, he performed research and published numerous papers and articles on topics such as networking, operating systems, artificial intelligence, and programming languages for distributed computing applications. His most notable work was on the Mach kernel.

ACM SIGOPS is the Association for Computing Machinery's Special Interest Group on Operating Systems, an international community of students, faculty, researchers, and practitioners associated with research and development related to operating systems. The organization sponsors prestigious international conferences related to computer systems, operating systems, computer architectures, distributed computing, and virtual environments. In addition, the organization offers multiple awards recognizing outstanding participants in the field, including the Dennis M. Ritchie Doctoral Dissertation Award, in honor of Dennis Ritchie, co-creator of the renowned C programming language and Unix operating system.Accent kernel
Accent was an operating system kernel developed at Carnegie Mellon University (CMU). Accent was developed as a follow-on to the Aleph kernel developed at the University of Rochester, fixing several of its problems and re-targeting its hardware support for networks of workstation machines (specifically, the Three Rivers PERQ) instead of minicomputers. Accent was part of the SPICE Project at CMU which ran from 1981 to 1985. Development of Accent led directly to the famous Mach kernel.
The original Aleph project used data copying to allow programs to communicate. Applications could open ports, which would allow them to receive data sent to them by other programs. The idea was to write a number of servers that would control resources on the machine, passing data along until it reached an end user. In this respect it was similar in concept to Unix, although the implementation was much different, using messages instead of memory. This turned out to have a number of problems, notably that copying memory on their Data General Eclipse was very expensive.
In 1979 one of the Aleph engineers, Richard Rashid, left for CMU and started work on a new version of Aleph that avoided its problems. In particular, Accent targeted workstation machines featuring a MMU, using the MMU to "copy" large blocks of memory via mapping, making the memory appear to be in two different places. Only data that was changed by one program or another would have to be physically copied, using the copy-on-write algorithm.
To understand the difference, consider two interacting programs, one feeding a file to another. Under Aleph the data from the provider would have to be copied 2kB at a time (due to features of the Eclipse) into the user process. Under Accent the data simply "appeared" in the user process for the cost of a few instructions sent to the MMU. Only if the user process changed the data would anything need to be copied, and even then, only the portions of the data that actually changed.
Another problem in Aleph was that its ports were identified by unique ID's that were assigned sequentially. It was simple for a program to "guess" them, thereby gaining access to resources on the computer that it had not been granted. This made the Aleph system rather insecure.
To address this, Accent made the port ID's internal to the kernel only. Instances of a program opening ports were handed back different IDs, stored in a mapping in the kernel. Whenever a message was sent to the kernel for delivery, it would first check that the program had access to the port in question by comparing with the mapping table for that program. Guessing port numbers no longer worked, the program's port IDs gave no clue of the "real" IDs in the kernel, and any attempt to talk on one not explicitly handed out by the kernel was an error. Thus Accent's ports represented capabilities, granting rights to use resources as the result of being handed a valid port ID. This kind of capability system, using subject-specific identifiers for capabilities, is called a C-list system.
After a few years the Accent project started looking less and less interesting. In the early 1980s many felt that future gains in performance would be made by adding more CPUs to machines, something the Accent kernel was not really equipped to handle. Adding to the problem was that a new generation of more powerful workstations were appearing, meaning that Accent would likely have to be ported to them anyway. Likewise Unix had grown into the operating system of choice for experimental work, both on operating system design, as well as a development platform for user applications.
In order to address these changes, it was decided to end work on Accent and start again. The new system would use Accent's ports system within a Unix kernel, creating the famed Mach kernel.
Some features of Accent:
Copy-on-write virtual memory management
Distributed file management
Distributed process management
Protected message-based inter-process communication
Ability to run processes with different microcoded instruction sets.Bing Audio
Bing Audio (also known as Bing Music) is a music recognition application created by Microsoft which is installed on Windows Phones running version 7.5 and above, including Windows Phone 8. On Windows Phone 8.1, and in regions where the Microsoft Cortana voice assistant is available, Bing Music is integrated with Cortana and the music search history is a part of Cortana's "Notebook". The service is only designed to recognize recorded songs, not live performances or humming. Xbox Music Pass subscribers can immediately add the songs to their playlists. A unique feature compared to similar services is that Bing Audio continuously listens and analyzes music while most other services can only listen for a fixed amount of time. Bing Research developed a fingerprinting algorithm to identify songs.On March 30, 2016 Microsoft announced that they'll create bots based on Bing features in Skype of which Bing Music was one.Bing Vision
Bing Vision is an image recognition application created by Microsoft which is installed on Windows Phones running version 7.5 and above, including Windows Phone 8. It is a part of the Bing Mobile suite of services, and on most devices can be accessed using the search button. On Windows Phone 8.1 devices where Microsoft Cortana is available, it is only available through the lenses of the Camera app (as the search button now activates Cortana). Bing Vision can scan barcodes, QR codes, Microsoft Tags, books, CDs, and DVDs. Books, CDs, and DVDs are offered through Bing Shopping.Carnegie Mellon University
Carnegie Mellon University (CMU) is a private research university based in Pittsburgh, Pennsylvania. Founded in 1900 by Andrew Carnegie as the Carnegie Technical Schools, the university became the Carnegie Institute of Technology in 1912 and began granting four-year degrees. In 1967, the Carnegie Institute of Technology merged with the Mellon Institute of Industrial Research to form Carnegie Mellon University. With its main campus located 3 miles (5 km) from Downtown Pittsburgh, Carnegie Mellon has grown into an international university with over a dozen degree-granting locations in six continents, including campuses in Qatar and Silicon Valley, and more than 20 research partnerships.The university has seven colleges and independent schools which all offer interdisciplinary programs: the College of Engineering, College of Fine Arts, Dietrich College of Humanities and Social Sciences, Mellon College of Science, Tepper School of Business, H. John Heinz III College of Information Systems and Public Policy, and the School of Computer Science.Carnegie Mellon counts 13,961 students from 109 countries, over 105,000 living alumni, and over 5,000 faculty and staff. Past and present faculty and alumni include 20 Nobel Prize laureates, 13 Turing Award winners, 23 Members of the American Academy of Arts and Sciences, 22 Fellows of the American Association for the Advancement of Science, 79 Members of the National Academies, 124 Emmy Award winners, 47 Tony Award laureates, and 10 Academy Award winners.Encarta
Microsoft Encarta was a digital multimedia encyclopedia published by Microsoft Corporation from 1993 to 2009. Originally sold on CD-ROM or DVD, it was also later available on the World Wide Web via an annual subscription – although later many articles could also be viewed free online with advertisements. By 2008, the complete English version, Encarta Premium, consisted of more than 62,000 articles, numerous photos and illustrations, music clips, videos, interactive content, timelines, maps, atlases and homework tools.
Microsoft published similar encyclopedias under the Encarta trademark in various languages, including German, French, Spanish, Dutch, Italian, Portuguese and Japanese. Localized versions contained contents licensed from national sources and more or less content than the full English version. For example, the Dutch version had content from the Dutch Winkler Prins encyclopedia.
In March 2009, Microsoft announced it was discontinuing both the Encarta disc and online versions. The MSN Encarta site was closed on October 31, 2009 in all countries except Japan, where it was closed on December 31, 2009. Microsoft continued to operate the Encarta online dictionary until 2011.High Capacity Color Barcode
High Capacity Color Barcode (HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes. Data density is increased by using a palette of 4 or 8 colors for the triangles, although HCCB also permits the use of black and white when necessary. It has been licensed by the ISAN International Agency for use in its International Standard Audiovisual Number standard, and serves as the basis for the Microsoft Tag mobile tagging application.
The technology was created by Gavin Jancke, an engineering director at Microsoft Research. Quoted by BBC News in 2007, he said that HCCB was not intended to replace conventional barcodes. "'It's more of a 'partner' barcode', he said. 'The UPC barcodes will always be there. Ours is more of a niche barcode where you want to put a lot of information in a small space.'"IEEE Emanuel R. Piore Award
The IEEE Emanuel R. Piore Award is a Technical Field Award given each year by the IEEE to an individual or team of two people who have made outstanding contributions to information processing systems in relation to computer science. The award is named in honor of Emanuel R. Piore.
The award was established in 1976. It could be presented to an individual or team of two.
Recipients of this award received a bronze medal, certificate, and honorarium.This award was discontinued by the IEEE Board of Directors in 2012.Jeff Eppinger
Jeffrey Lee Eppinger (born ca 1960) is an American computer scientist, entrepreneur and Professor of the Practice at the Carnegie Mellon University, School of Computer Science, Institute for Software Research.
Eppinger was a student at Carnegie Mellon University where he earned a Bachelor of Science in 1982, a Master of Science in 1987, and a PhD in Computer Science in 1988. His advisors were Alfred Spector and Richard Rashid.
Eppinger was a co-founder of Transarc Corporation, which was bought by IBM in 1994.
At Carnegie Mellon, Eppinger's dissertation demonstrated the integration of the Mach Operating System's virtual memory with the Camelot Transaction System. This recoverable virtual memory concept was subsequently used to implement the Coda File System.
In 1983, Eppinger won the George E. Forsythe Award for his research in binary search trees. Eppinger had made empirical studies of their behaviour under random deletions and insertions.Mach (kernel)
Mach () is a kernel developed at Carnegie Mellon University to support operating system research, primarily distributed and parallel computing. Mach is often mentioned as one of the earliest examples of a microkernel. However, not all versions of Mach are microkernels. Mach's derivatives are the basis of the modern operating system kernels in GNU Hurd and Apple's operating systems macOS, iOS, tvOS, and watchOS.
The project at Carnegie Mellon ran from 1985 to 1994, ending with Mach 3.0, which is a true microkernel. Mach was developed as a replacement for the kernel in the BSD version of Unix, so no new operating system would have to be designed around it. Mach and its derivatives exist within a number of commercial operating systems. These include all using the XNU operating system kernel which incorporates an earlier non-microkernel Mach as a major component. The Mach virtual memory management system was also adopted in 4.4BSD by the BSD developers at CSRG, and appears in modern BSD-derived Unix systems, such as FreeBSD.
Mach is the logical successor to Carnegie Mellon's Accent kernel. The lead developer on the Mach project, Richard Rashid, has been working at Microsoft since 1991 in various top-level positions revolving around the Microsoft Research division. Another of the original Mach developers, Avie Tevanian, was formerly head of software at NeXT, then Chief Software Technology Officer at Apple Inc. until March 2006.Microsoft Office
Microsoft Office (or simply Office) is a family of client software, server software, and services developed by Microsoft. It was first announced by Bill Gates on August 1, 1988, at COMDEX in Las Vegas. Initially a marketing term for an office suite (bundled set of productivity applications), the first version of Office contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, OLE data integration and Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. On July 10, 2012, Softpedia reported that Office is used by over a billion people worldwide.Office is produced in several versions targeted towards different end-users and computing environments. The original, and most widely used version, is the desktop version, available for PCs running the Windows and macOS operating systems. Office Online is a version of the software that runs within a web browser, while Microsoft also maintains Office apps for Android and iOS.
Since Office 2013, Microsoft has promoted Office 365 as the primary means of obtaining Microsoft Office: it allows use of the software and other services on a subscription business model, and users receive free feature updates to the software for the lifetime of the subscription, including new features and cloud computing integration that are not necessarily included in the "on-premises" releases of Office sold under conventional license terms. In 2017, revenue from Office 365 overtook conventional license sales.
The current on-premises, desktop version of Office is Office 2019, released on September 24, 2018.Microsoft Store
Microsoft Store is a chain of retail stores and an online shopping site, owned and operated by Microsoft and dealing in computers, computer software and consumer electronics.
The Microsoft Store offers Signature PCs and tablets like the Microsoft Surface and from third parties such as HP, Acer, Dell, Lenovo, and VAIO without demos or trialware (pre-installed free trials of certain third-party software that expire after a limited time). It also offers Windows (most retail versions), Microsoft Office and Xbox One game consoles, games and services including on-site Xbox diagnostics. The Answers Desk helps to answer questions related to Windows, Office, and other Microsoft products. The stores also offer class sessions as well as individual appointments.
The first two Microsoft Stores opened within a week of the Windows 7 launch, in Scottsdale, Arizona and Mission Viejo, California. Additional stores have since opened in California, Colorado, Florida, Georgia, Illinois, Minnesota, Missouri, Texas and Washington. At the 2011 Professional Developers Conference, Microsoft announced that they intend to open 75 new stores in the next three years.The first store outside the U.S. (and the first of eight stores in Canada) opened in Toronto on November 16, 2012 while the first store outside North America (and first store in Asia-Pacific and second flagship store) opened in Sydney, Australia on November 12, 2015 In September 2017, the company announced a store on Regent Street in London, United Kingdom .Microsoft Teams
Microsoft Teams is a unified communications platform that combines persistent workplace chat, video meetings, file storage (including collaboration on files), and application integration. The service integrates with the company's Office 365 subscription office productivity suite and features extensions that can integrate with non-Microsoft products. Microsoft Teams is a competitor to services such as Slack and is the evolution and upgrade path from Microsoft Skype for Business.
Microsoft announced Teams at an event in New York, and launched the service worldwide on 14 March 2017. It was created, and is currently led, by Brian MacDonald, Corporate Vice President at Microsoft.Outline of Microsoft
Microsoft Corporation is a multinational corporation based in Redmond, Washington, USA and founded by Bill Gates and Paul Allen that develops, manufactures, licenses, and supports a wide range of products and services predominantly related to computing. Due to the scope and size of the company, it encompasses a broad range of topics mostly revolving around critical analysis and the company's products and services.Rashid (name)
Rashid (spelled also Rachid) is the transliteration of two male given names: Arabic: راشد,
Rāshid and Arabic: رشيد, Rashīd.
The latter name has a diacritic, in the strict transliteration, on the "I", which emphasises the long "I" sound in that name's pronunciation.
Ar-Rashid is one of the 99 Names of Allah meaning The Guide.Read-copy-update
In computer science, read-copy-update (RCU) is a synchronization mechanism based on mutual exclusion. It is used when performance of reads is crucial and is an example of space–time tradeoff, enabling fast operations at the cost of more space.
Read-copy-update allows multiple threads to efficiently read from shared memory by deferring updates after pre-existing reads to a later time while simultaneously marking the data, ensuring new readers will read the updated data. This makes all readers proceed as if there were no synchronization involved, hence they will be fast, but also making updates more difficult.Satya Nadella
Satya Narayana Nadella (; born 19 August 1967) is an Indian-American business executive. He currently serves as the Chief Executive Officer (CEO) of Microsoft, succeeding Steve Ballmer in 2014. Before becoming chief executive, he was Executive Vice President of Microsoft's Cloud and Enterprise Group, responsible for building and running the company's computing platforms.Surface Studio
