John Heidemann
John Heidemann is an engineer at the USC Information Sciences Institute in Marina del Rey, California. He was named a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2014 for his contributions to sensor networks, internet measurement, and simulations. He has authored more than two hundred and fifty scholarly papers in these fields. His research has been supported by the American National Science Foundation, among others. John Heidemann was very active in the field of sensor networks in the 2000s. With Nirupama Bulusu and Deborah Estrin, he developed the first wireless, range-free localization system for wireless sensor networks. With Wei Ye and Deborah Estrin he developed S-MAC, an early energy-conserving media access protocol for wireless networks. During the next decade, his work examined Internet measurement, including the first complete IPv4 census (scan) in 2006, techniques to detect network outages in the Internet, and evaluation of anycast stabili ...

Engineer
Engineers, as practitioners of engineering, are professionals who Invention, invent, design, build, maintain and test machines, complex systems, structures, gadgets and materials. They aim to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin , the origin of the Ir. in the title of engineer in countries like Belgium, The Netherlands, and Indonesia) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year Bachelor of Engineering, bache ...

GNU ELPA
GNU ( ) is an extensive collection of free software (394 packages ), which can be used as an operating system or can be used in parts with other operating systems. The use of the completed GNU tools led to the family of operating systems popularly known as Linux. Most of GNU is licensed under the GNU Project's own General Public License ( GPL). GNU is also the project within which the free software concept originated. Richard Stallman, the founder of the project, views GNU as a "technical means to a social end". Relatedly, Lawrence Lessig states in his introduction to the second edition of Stallman's book '' Free Software, Free Society'' that in it Stallman has written about "the social aspects of software and how Free Software can create community and social justice". Name ''GNU'' is a recursive acronym for "GNU's Not Unix!", chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code. Stallman chose the name by usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Gazette
''The Linux Gazette'' was a monthly self-published Linux computing webzine, published between July 1995 and June 2011. Its content was published under the Open Publication License. History It was started in July 1995 by John M. Fisk as a free service. He went on to pursue his studies and become a medical doctor. At Mr. Fisk's request, the publication was sponsored and managed by SSC ( Specialized System Consultants, who at that time were also publishers of Linux Journal). The content was always provided by volunteers, including most of the editorial oversight. After those years, the volunteer staff and the management of SSC had a schism (see Bifurcation below). Both the volunteer-run magazine and the magazine run by SSC has been closed down. One way Linux Gazette differed from other, similar, webzines (and magazines) was ''The Answer Gang''. In addition to providing a regular page devoted to questions and answers, questions to The Answer Gang were answered on a mailing list ...

Note-taking
Note-taking (sometimes written as notetaking or note taking) is the practice of recording information from different sources and platforms. By taking notes, the writer records the essence of the information, freeing their mind from having to Recall (memory), recall everything. Notes are commonly drawn from a transient source, such as an oral discussion at a meeting, or a lecture (notes of a meeting are usually called minutes), in which case the notes may be the only record of the event. Since the advent of writing and literacy, notes traditionally were almost always handwriting, handwritten (often in notebooks), but the introduction of comparison of note-taking software, notetaking software and Website, websites has made digital notetaking possible and widespread. Note-taking is a foundational skill in personal knowledge management. History Note-taking has been an important part of human history and scientific development. The Ancient Greeks developed hypomnema, personal record ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Emacs
GNU Emacs is a text editor and suite of free software tools. Its development began in 1984 by GNU Project founder Richard Stallman, based on the Emacs editor developed for Unix operating systems. GNU Emacs has been a central component of the GNU project and a flagship project of the free software movement. The program's tagline is "the extensible self-documenting text editor." Most functionality in GNU Emacs is implemented in user-accessible Emacs Lisp, allowing deep extensibility directly by users and through community-contributed packages. Its built-in features include a file browser and editor (Dired), an advanced calculator (Calc), an email client and news reader (Gnus), a Language Server Protocol integration, and the productivity system Org-mode. A large community of users have contributed extensions such as the Git interface Magit, the Vim (text editor), Vim emulation layer Evil, several search frameworks, the window manager EXWM, and tools for working with a wide range of p ...

Ns (simulator)
ns (from network simulator) is a name for a series of discrete event network simulators, specifically ns-1, ns-2, and ns-3. All are discrete-event computer network simulators, primarily used in research and teaching. History ns-1 The first version of ns, known as ns-1, was developed at Lawrence Berkeley National Laboratory (LBNL) in the 1995-97 timeframe by Steve McCanne, Sally Floyd, Kevin Fall, and other contributors. This was known as the LBNL Network Simulator, and derived in 1989 from an earlier simulator known as REAL by S. Keshav. ns-2 Ns-2 began as a revision of ns-1. From 1997 to 2000, ns development was supported by DARPA through the VINT project at LBL, Xerox PARC, UC Berkeley, and USC/ISI. In 2000, ns-2 development was supported through DARPA with SAMAN and through NSF with CONSER, both at USC/ISI, in collaboration with other researchers including ACIRI. Features of NS2 1.

Wireless Sensor Network
Wireless sensor networks (WSNs) refer to networks of spatially dispersed and dedicated sensors that monitor and record the physical conditions of the environment and forward the collected data to a central location. WSNs can measure environmental conditions such as temperature, sound, pollution levels, humidity and wind. These are similar to wireless ad hoc networks in the sense that they rely on wireless connectivity and spontaneous formation of networks so that sensor data can be transported wirelessly. WSNs monitor physical conditions, such as temperature, sound, and pressure. Modern networks are bi-directional, both collecting data and enabling control of sensor activity. The development of these networks was motivated by military applications such as battlefield surveillance. Such networks are used in industrial and consumer applications, such as industrial process monitoring and control and machine health monitoring and agriculture. A WSN is built of "nodes" – from a ...
