the readers-writers problems are examples of a common computing problem in concurrency. There are at least three variations of the problems, which deal with situations in which many threads try to access the same shared resource at one time. Some threads may read and some may write, with the constraint that no process may access the share for either reading or writing, while another process is in the act of writing to it. (In particular, it is allowed for two or more readers to access the share at the same time.) A readers-writer lock is a data structure that solves one or more of the readers-writers problems.
Dining philosopher problem is one of classical process synchronization problem. This problem state that there are five philosopher who spent their life in thinking and eating. There are five forks available on the table. How forks can be assigned to philosopher so that there won't be any problem of Deadlock and starvation.
Tim Poston tells about every detailing that goes into writing a science fiction. Every component in a fictional book is supported by existing scientific theories. He explains the geographical intricacies of a different planet which plays the backdrop in the story. He presents the fictional story in a factually believable manner by providing phenomenal explanation. Timothy "Tim" Poston (born 19 June 1945 in St Albans, Hertfordshire) is an English mathematician best known for his work on catastrophe theory. His 1972 Ph.D at the University of Warwick was directed by Christopher Zeeman on "Fuzzy Geometry". Tim specializes in geometry, graphics, algorithm design, human-computer interaction, medical imaging, patent writing and singularity theory. His books on catastrophe theory and ...
Google’s Hummingbird algorithm in 2013 was a game-changer for content creators. It is no longer enough to crowbar lots of keywords into our website and blog content, because Google has started going beyond the individual words people USE when they search, to figure out what they MEAN. Our content has to answer those questions if we want it returned on Page 1 of Google. In this webinar Emily Hill will provide practical tips to help you write content that answers the real questions in your customers’ minds when they run search queries. Emily is the founder and CEO of a 9-year old copywriting agency that has undergone a big transformation of its own in the way it approaches content creation for clients. Therefore a lot of the examples in this webinar are based on techniques that Emily has i...
Jacinta Catherine Richardson http://linux.conf.au/schedule/presentation/69/ Data structures and algorithms are essential tools in the developer's toolkit, yet it is an area that is too easy to get behind in. The essential algorithms you learned whenever you did Computer Science probably included: 1. Shortest path and tree (and graph) traversals - depth-first, breadth first, cycle management 2. Sorting - quick sort, bubble sort, merge sort, binary sort 3. Searching - binary trees, B-trees, B+trees, red-black trees 4. Specific problems - knapsack problem, painters algorithm, decision trees 5. Algorithm tecniques - divide and conquer, backtracking, creating NFAs You might also have learned the Fast Fourier Transform (FFT) and the Convolution theorem. For data structures you migh...
This is a operating system deadlock problem. This video is about the dining philosopher deadlock problem and its solution using semaphores.
This video introduces the creation of macros in Excel using VBA. The intro is oriented towards engineers and is part of a course I teach in an online Masters program. The program is described at http://mepp.engr.wisc.edu and high res versions of this and other videos is available at http://blanchard.ep.wisc.edu There is also a demonstration video on the same topic at the same site.
