Google’s PageRank patent has expired

Another aspect of the invention is directed to a technique for ranking documents within a database whose content has a large variation in quality and importance. Another aspect of the present invention is to provide a document ranking method that is scalable and can be applied to extremely large databases such as the world wide web. A linked database (i.e. any database of documents containing mutual citations, such as the world wide web or other hypermedia archive, a dictionary or thesaurus, and a database of academic articles, patents, or court cases) can be represented as a directed graph of N nodes, where each node corresponds to a web page document and where the directed connections between nodes correspond to links from one document to another.

U.S. DoD bought phony military gear made in China

U.S. DoD bought phony military gear made in China

The U.S. military, government agencies and other purchasers bought more than $20 million worth of Chinese-made counterfeit goods designed to look like domestically produced gear from a company that defrauded the government and helped to orchestrate the counterfeiting process between January 2013 and October 2018, Justice Department officials said last week. Kohanbash would then sell the gear to “other wholesalers who ultimately marketed and sold them to military and government buyers off as genuine, American-made products,” justice officials said in a news release. For instance, the labels on counterfeit hoods intended for military and law enforcement personnel stated that the items were “permanently flame resistant,” and that they met a specific industry standard for flame-resistant attire, justice officials said.

Researchers shed light on the complex evolutionary past of bedbugs

Researchers shed light on the complex evolutionary past of bedbugs

Work by an international team of scientists, including the University of Sheffield, compared the DNA of dozens of bedbug species in order to understand the evolutionary relationships within the group as well as their relationship with humans. Professor Mike Siva-Jothy from the University of Sheffield’s Department of Animal and Plant Sciences, who was part of the team, said: “To think that the pests that live in our beds today evolved more than 100 million years ago and were walking the earth side by side with dinosaurs, was a revelation. Professor Klaus Reinhardt, a bedbug researcher from Dresden University in Germany, who co-led the study, said: “These species are the ones we can reasonably expect to be the next ones drinking our blood, and it may not even take half a million years, given that many more humans, livestock and pets that live on earth now provide lots more opportunities.”

The volatile era that gave rise to Jane Austen and Lord Byron

The volatile era that gave rise to Jane Austen and Lord Byron

In “The Regency Years” Robert Morrison showcases that relatively brief period — less than a decade — as an age of “remarkable diversity, upheaval, and elegance,” during which, in the words of his subtitle, “Jane Austen Writes, Napoleon Fights, Byron Makes Love, and Britain Becomes Modern.” [A new look at Gatsby — as an Oxford man]
In other sections of “The Regency Years” Morrison probes the era’s passion for gambling, horse-racing, boxing and opium (his previous book was an excellent biography of Thomas De Quincey). THE REGENCY YEARS
During Which Jane Austen Writes, Napoleon Fights, Byron Makes Love, and Britain Becomes Modern

The degrowth movement wants to intentionally shrink the economy

The degrowth movement wants to intentionally shrink the economy

This skepticism has led to the degrowth movement, which says the growth of the economy is inextricably tied to an increase in carbon emissions. Robert Pollin, a professor of economics at the University of Massachusetts Amherst and co-director of the political economy research institute there, said that while he shares many of the degrowth movement’s sentiments, he fundamentally disagrees that such a system could work, at least in the time we need it to. And a pull toward degrowth may reflect more than just an urge for minimalism, but also fatigue in a system where growth hasn’t produced big wins for many people.

Lisp System Implementation

Lisp System Implementation

This book delves straight into the internals of an interactive LISP system. Emphasis is on compilation to abstract machine code, but lots of topics will be discussed at length, including:

LISP data objects, syntax analysis, closure conversion, lambda lifting, operational semantics, bytecode generation, bytecode interpretation, primitive functions, bootstrapping LISP code, macro expansion, lexical and dynamic binding, tail call elimination, garbage collection, non-local exits, the read-eval-print loop (REPL), reading and printing LISP objects, input and output ports, error handling, heap image files, etc …

The C and LISP code in this book is comprehensible rather than clever. In the final part of the book, compilation of LISP-N, compilation to stand-alone binaries, and compilation to native machine code are outlined.

Facebook reportedly argues there’s no ‘expectation of privacy’ on social media

Facebook reportedly argues there’s no ‘expectation of privacy’ on social media

Facebook on Wednesday reportedly argued that it didn’t violate users’ privacy rights because there’s no expectation of privacy when using social media. The company reportedly didn’t deny that third parties accessed users’ data, but it instead told US District Judge Vince Chhabria that there’s no “reasonable expectation of privacy” on Facebook or any other social media site. The company’s data-handling practices have been called into question in the wake of the 2018 Cambridge Analytica scandal, during which personal information on up to 87 million Facebook users was improperly accessed.
