British computer scientist’s new “nullity” idea provokes reaction from mathematicians

Monday, December 11, 2006

On December 7, BBC News reported a story about Dr James Anderson, a teacher in the Computer Science department at the University of Reading in the United Kingdom. In the report it was stated that Anderson had “solved a very important problem” that was 1200 years old, the problem of division by zero. According to the BBC, Anderson had created a new number, that he had named “nullity”, that lay outside of the real number line. Anderson terms this number a “transreal number”, and denotes it with the Greek letter ? {\displaystyle \Phi } . He had taught this number to pupils at Highdown School, in Emmer Green, Reading.

The BBC report provoked many reactions from mathematicians and others.

In reaction to the story, Mark C. Chu-Carroll, a computer scientist and researcher, posted a web log entry describing Anderson as an “idiot math teacher”, and describing the BBC’s story as “absolutely infuriating” and a story that “does an excellent job of demonstrating what total innumerate idiots reporters are”. Chu-Carroll stated that there was, in fact, no actual problem to be solved in the first place. “There is no number that meaningfully expresses the concept of what it means to divide by zero.”, he wrote, stating that all that Anderson had done was “assign a name to the concept of ‘not a number'”, something which was “not new” in that the IEEE floating-point standard, which describes how computers represent floating-point numbers, had included a concept of “not a number”, termed “NaN“, since 1985. Chu-Carroll further continued:

“Basically, he’s defined a non-solution to a non-problem. And by teaching it to his students, he’s doing them a great disservice. They’re going to leave his class believing that he’s a great genius who’s solved a supposed fundamental problem of math, and believing in this silly nullity thing as a valid mathematical concept.
“It’s not like there isn’t already enough stuff in basic math for kids to learn; there’s no excuse for taking advantage of a passive audience to shove this nonsense down their throats as an exercise in self-aggrandizement.
“To make matters worse, this idiot is a computer science professor! No one who’s studied CS should be able to get away with believing that re-inventing the concept of NaN is something noteworthy or profound; and no one who’s studied CS should think that defining meaningless values can somehow magically make invalid computations produce meaningful results. I’m ashamed for my field.”

There have been a wide range of other reactions from other people to the BBC news story. Comments range from the humorous and the ironic, such as the B1FF-style observation that “DIVIDION[sic] BY ZERO IS IMPOSSIBLE BECAUSE MY CALCULATOR SAYS SO AND IT IS THE TRUTH” and the Chuck Norris Fact that “Only Chuck Norris can divide by zero.” (to which another reader replied “Chuck Norris just looks at zero, and it divides itself.”); through vigourous defences of Dr Anderson, with several people quoting the lyrics to Ira Gershwin‘s song “They All Laughed (At Christopher Columbus)”; to detailed mathematical discussions of Anderson’s proposed axioms of transfinite numbers.

Several readers have commented that they consider this to have damaged the reputation of the Computer Science department, and even the reputation of the University of Reading as a whole. “By publishing his childish nonsense the BBC actively harms the reputation of Reading University.” wrote one reader. “Looking forward to seeing Reading University maths application plummit.” wrote another. “Ignore all research papers from the University of Reading.” wrote a third. “I’m not sure why you refer to Reading as a ‘university’. This is a place the BBC reports as closing down its physics department because it’s too hard. Lecturers at Reading should stick to folk dancing and knitting, leaving academic subjects to grown ups.” wrote a fourth. Steve Kramarsky lamented that Dr Anderson is not from the “University of ‘Rithmetic“.

Several readers criticised the journalists at the BBC who ran the story for not apparently contacting any mathematicians about Dr Anderson’s idea. “Journalists are meant to check facts, not just accept whatever they are told by a self-interested third party and publish it without question.” wrote one reader on the BBC’s web site. However, on Slashdot another reader countered “The report is from Berkshire local news. Berkshire! Do you really expect a local news team to have a maths specialist? Finding a newsworthy story in Berkshire probably isn’t that easy, so local journalists have to cover any piece of fluff that comes up. Your attitude to the journalist should be sympathy, not scorn.”

Ben Goldacre, author of the Bad Science column in The Guardian, wrote on his web log that “what is odd is a reporter, editor, producer, newsroom, team, cameraman, soundman, TV channel, web editor, web copy writer, and so on, all thinking it’s a good idea to cover a brilliant new scientific breakthrough whilst clearly knowing nothing about the context. Maths isn’t that hard, you could even make a call to a mathematician about it.”, continuing that “it’s all very well for the BBC to think they’re being balanced and clever getting Dr Anderson back in to answer queries about his theory on Tuesday, but that rather skips the issue, and shines the spotlight quite unfairly on him (he looks like a very alright bloke to me).”.

From reading comments on his own web log as well as elsewhere, Goldacre concluded that he thought that “a lot of people might feel it’s reporter Ben Moore, and the rest of his doubtless extensive team, the people who drove the story, who we’d want to see answering the questions from the mathematicians.”.

Andrej Bauer, a professional mathematician from Slovenia writing on the Bad Science web log, stated that “whoever reported on this failed to call a university professor to check whether it was really new. Any university professor would have told this reporter that there are many ways of dealing with division by zero, and that Mr. Anderson’s was just one of known ones.”

Ollie Williams, one of the BBC Radio Berkshire reporters who wrote the BBC story, initially stated that “It seems odd to me that his theory would get as far as television if it’s so easily blown out of the water by visitors to our site, so there must be something more to it.” and directly responded to criticisms of BBC journalism on several points on his web log.

He pointed out that people should remember that his target audience was local people in Berkshire with no mathematical knowledge, and that he was “not writing for a global audience of mathematicians”. “Some people have had a go at Dr Anderson for using simplified terminology too,” he continued, “but he knows we’re playing to a mainstream audience, and at the time we filmed him, he was showing his theory to a class of schoolchildren. Those circumstances were never going to breed an in-depth half-hour scientific discussion, and none of our regular readers would want that.”.

On the matter of fact checking, he replied that “if you only want us to report scientific news once it’s appeared, peer-reviewed, in a recognised journal, it’s going to be very dry, and it probably won’t be news.”, adding that “It’s not for the BBC to become a journal of mathematics — that’s the job of journals of mathematics. It’s for the BBC to provide lively science reporting that engages and involves people. And if you look at the original page, you’ll find a list as long as your arm of engaged and involved people.”.

Williams pointed out that “We did not present Dr Anderson’s theory as gospel, although with hindsight it could have been made clearer that this is very much a theory and by no means universally accepted. But we certainly weren’t shouting a mathematical revolution from the rooftops. Dr Anderson has, in one or two places, been chastised for coming to the media with his theory instead of his peers — a sure sign of a quack, boffin and/or crank according to one blogger. Actually, one of our reporters happened to meet him during a demonstration against the closure of the university’s physics department a couple of weeks ago, got chatting, and discovered Dr Anderson reckoned he was onto something. He certainly didn’t break the door down looking for media coverage.”.

Some commentators, at the BBC web page and at Slashdot, have attempted serious mathematical descriptions of what Anderson has done, and subjected it to analysis. One description was that Anderson has taken the field of real numbers and given it complete closure so that all six of the common arithmetic operators were surjective functions, resulting in “an object which is barely a commutative ring (with operators with tons of funky corner cases)” and no actual gain “in terms of new theorems or strong relation statements from the extra axioms he has to tack on”.

Jamie Sawyer, a mathematics undergraduate at the University of Warwick writing in the Warwick Maths Society discussion forum, describes what Anderson has done as deciding that R ? { ? ? , + ? } {\displaystyle \mathbb {R} \cup \lbrace -\infty ,+\infty \rbrace } , the so-called extended real number line, is “not good enough […] because of the wonderful issue of what 0 0 {\displaystyle {\frac {0}{0}}} is equal to” and therefore creating a number system R ? { ? ? , ? , + ? } {\displaystyle \mathbb {R} \cup \lbrace -\infty ,\Phi ,+\infty \rbrace } .

Andrej Bauer stated that Anderson’s axioms of transreal arithmetic “are far from being original. First, you can adjoin + ? {\displaystyle +\infty } and ? ? {\displaystyle -\infty } to obtain something called the extended real line. Then you can adjoin a bottom element to represent an undefined value. This is all standard and quite old. In fact, it is well known in domain theory, which deals with how to represent things we compute with, that adjoining just bottom to the reals is not a good idea. It is better to adjoin many so-called partial elements, which denote approximations to reals. Bottom is then just the trivial approximation which means something like ‘any real’ or ‘undefined real’.”

Commentators have pointed out that in the field of mathematical analysis, 0 0 {\displaystyle {\frac {0}{0}}} (which Anderson has defined axiomatically to be ? {\displaystyle \Phi } ) is the limit of several functions, each of which tends to a different value at its limit:

  • lim x ? 0 x 0 {\displaystyle \lim _{x\to 0}{\frac {x}{0}}} has two different limits, depending from whether x {\displaystyle x} approaches zero from a positive or from a negative direction.
  • lim x ? 0 0 x {\displaystyle \lim _{x\to 0}{\frac {0}{x}}} also has two different limits. (This is the argument that commentators gave. In fact, 0 x {\displaystyle {\frac {0}{x}}} has the value 0 {\displaystyle 0} for all x ? 0 {\displaystyle x\neq 0} , and thus only one limit. It is simply discontinuous for x = 0 {\displaystyle x=0} . However, that limit is different to the two limits for lim x ? 0 x 0 {\displaystyle \lim _{x\to 0}{\frac {x}{0}}} , supporting the commentators’ main point that the values of the various limits are all different.)
  • Whilst sin ? 0 = 0 {\displaystyle \sin 0=0} , the limit lim x ? 0 sin ? x x {\displaystyle \lim _{x\to 0}{\frac {\sin x}{x}}} can be shown to be 1, by expanding the sine function as an infinite Taylor series, dividing the series by x {\displaystyle x} , and then taking the limit of the result, which is 1.
  • Whilst 1 ? cos ? 0 = 0 {\displaystyle 1-\cos 0=0} , the limit lim x ? 0 1 ? cos ? x x {\displaystyle \lim _{x\to 0}{\frac {1-\cos x}{x}}} can be shown to be 0, by expanding the cosine function as an infinite Taylor series, dividing the series subtracted from 1 by x {\displaystyle x} , and then taking the limit of the result, which is 0.

Commentators have also noted l’Hôpital’s rule.

It has been pointed out that Anderson’s set of transreal numbers is not, unlike the set of real numbers, a mathematical field. Simon Tatham, author of PuTTY, stated that Anderson’s system “doesn’t even think about the field axioms: addition is no longer invertible, multiplication isn’t invertible on nullity or infinity (or zero, but that’s expected!). So if you’re working in the transreals or transrationals, you can’t do simple algebraic transformations such as cancelling x {\displaystyle x} and ? x {\displaystyle -x} when both occur in the same expression, because that transformation becomes invalid if x {\displaystyle x} is nullity or infinity. So even the simplest exercises of ordinary algebra spew off a constant stream of ‘unless x is nullity’ special cases which you have to deal with separately — in much the same way that the occasional division spews off an ‘unless x is zero’ special case, only much more often.”

Tatham stated that “It’s telling that this monstrosity has been dreamed up by a computer scientist: persistent error indicators and universal absorbing states can often be good computer science, but he’s stepped way outside his field of competence if he thinks that that also makes them good maths.”, continuing that Anderson has “also totally missed the point when he tries to compute things like 0 0 {\displaystyle 0^{0}} using his arithmetic. The reason why things like that are generally considered to be ill-defined is not because of a lack of facile ‘proofs’ showing them to have one value or another; it’s because of a surfeit of such ‘proofs’ all of which disagree! Adding another one does not (as he appears to believe) solve any problem at all.” (In other words: 0 0 {\displaystyle 0^{0}} is what is known in mathematical analysis as an indeterminate form.)

To many observers, it appears that Anderson has done nothing more than re-invent the idea of “NaN“, a special value that computers have been using in floating-point calculations to represent undefined results for over two decades. In the various international standards for computing, including the IEEE floating-point standard and IBM’s standard for decimal arithmetic, a division of any non-zero number by zero results in one of two special infinity values, “+Inf” or “-Inf”, the sign of the infinity determined by the signs of the two operands (Negative zero exists in floating-point representations.); and a division of zero by zero results in NaN.

Anderson himself denies that he has re-invented NaN, and in fact claims that there are problems with NaN that are not shared by nullity. According to Anderson, “mathematical arithmetic is sociologically invalid” and IEEE floating-point arithmetic, with NaN, is also faulty. In one of his papers on a “perspex machine” dealing with “The Axioms of Transreal Arithmetic” (Jamie Sawyer writes that he has “worries about something which appears to be named after a plastic” — “Perspex” being a trade name for polymethyl methacrylate in the U.K..) Anderson writes:

We cannot accept an arithmetic in which a number is not equal to itself (NaN != NaN), or in which there are three kinds of numbers: plain numbers, silent numbers, and signalling numbers; because, on writing such a number down, in daily discourse, we can not always distinguish which kind of number it is and, even if we adopt some notational convention to make the distinction clear, we cannot know how the signalling numbers are to be used in the absence of having the whole program and computer that computed them available. So whilst IEEE floating-point arithmetic is an improvement on real arithmetic, in so far as it is total, not partial, both arithmetics are invalid models of arithmetic.

In fact, the standard convention for distinguishing the two types of NaNs when writing them down can be seen in ISO/IEC 10967, another international standard for how computers deal with numbers, which uses “qNaN” for non-signalling (“quiet”) NaNs and “sNaN” for signalling NaNs. Anderson continues:

[NaN’s] semantics are not defined, except by a long list of special cases in the IEEE standard.

“In other words,” writes Scott Lamb, a BSc. in Computer Science from the University of Idaho, “they are defined, but he doesn’t like the definition.”.

The main difference between nullity and NaN, according to both Anderson and commentators, is that nullity compares equal to nullity, whereas NaN does not compare equal to NaN. Commentators have pointed out that in very short order this difference leads to contradictory results. They stated that it requires only a few lines of proof, for example, to demonstrate that in Anderson’s system of “transreal arithmetic” both 1 = 2 {\displaystyle 1=2} and 1 ? 2 {\displaystyle 1\neq 2} , after which, in one commentator’s words, one can “prove anything that you like”. In aiming to provide a complete system of arithmetic, by adding extra axioms defining the results of the division of zero by zero and of the consequent operations on that result, half as many again as the number of axioms of real-number arithmetic, Anderson has produced a self-contradictory system of arithmetic, in accordance with Gödel’s incompleteness theorems.

One reader-submitted comment appended to the BBC news article read “Step 1. Create solution 2. Create problem 3. PROFIT!”, an allusion to the business plan employed by the underpants gnomes of the comedy television series South Park. In fact, Anderson does plan to profit from nullity, having registered on the 27th of July, 2006 a private limited company named Transreal Computing Ltd, whose mission statement is “to develop hardware and software to bring you fast and safe computation that does not fail on division by zero” and to “promote education and training in transreal computing”. The company is currently “in the research and development phase prior to trading in hardware and software”.

In a presentation given to potential investors in his company at the ANGLE plc showcase on the 28th of November, 2006, held at the University of Reading, Anderson stated his aims for the company as being:

To investors, Anderson makes the following promises:

  • “I will help you develop a curriculum for transreal arithmetic if you want me to.”
  • “I will help you unify QED and gravitation if you want me to.”
  • “I will build a transreal supercomputer.”

He asks potential investors:

  • “How much would you pay to know that the engine in your ship, car, aeroplane, or heart pacemaker won’t just stop dead?”
  • “How much would you pay to know that your Government’s computer controlled military hardware won’t just stop or misfire?”

The current models of computer arithmetic are, in fact, already designed to allow programmers to write programs that will continue in the event of a division by zero. The IEEE’s Frequently Asked Questions document for the floating-point standard gives this reply to the question “Why doesn’t division by zero (or overflow, or underflow) stop the program or trigger an error?”:

“The [IEEE] 754 model encourages robust programs. It is intended not only for numerical analysts but also for spreadsheet users, database systems, or even coffee pots. The propagation rules for NaNs and infinities allow inconsequential exceptions to vanish. Similarly, gradual underflow maintains error properties over a precision’s range.
“When exceptional situations need attention, they can be examined immediately via traps or at a convenient time via status flags. Traps can be used to stop a program, but unrecoverable situations are extremely rare. Simply stopping a program is not an option for embedded systems or network agents. More often, traps log diagnostic information or substitute valid results.”

Simon Tatham stated that there is a basic problem with Anderson’s ideas, and thus with the idea of building a transreal supercomputer: “It’s a category error. The Anderson transrationals and transreals are theoretical algebraic structures, capable of representing arbitrarily big and arbitrarily precise numbers. So the question of their error-propagation semantics is totally meaningless: you don’t use them for down-and-dirty error-prone real computation, you use them for proving theorems. If you want to use this sort of thing in a computer, you have to think up some concrete representation of Anderson transfoos in bits and bytes, which will (if only by the limits of available memory) be unable to encompass the entire range of the structure. And the point at which you make this transition from theoretical abstract algebra to concrete bits and bytes is precisely where you should also be putting in error handling, because it’s where errors start to become possible. We define our theoretical algebraic structures to obey lots of axioms (like the field axioms, and total ordering) which make it possible to reason about them efficiently in the proving of theorems. We define our practical number representations in a computer to make it easy to detect errors. The Anderson transfoos are a consequence of fundamentally confusing the one with the other, and that by itself ought to be sufficient reason to hurl them aside with great force.”

Geomerics, a start-up company specializing in simulation software for physics and lighting and funded by ANGLE plc, had been asked to look into Anderson’s work by an unnamed client. Rich Wareham, a Senior Research and Development Engineer at Geomerics and a MEng. from the University of Cambridge, stated that Anderson’s system “might be a more interesting set of axioms for dealing with arithmetic exceptions but it isn’t the first attempt at just defining away the problem. Indeed it doesn’t fundamentally change anything. The reason computer programs crash when they divide by zero is not that the hardware can produce no result, merely that the programmer has not dealt with NaNs as they propagate through. Not dealing with nullities will similarly lead to program crashes.”

“Do the Anderson transrational semantics give any advantage over the IEEE ones?”, Wareham asked, answering “Well one assumes they have been thought out to be useful in themselves rather than to just propagate errors but I’m not sure that seeing a nullity pop out of your code would lead you to do anything other than what would happen if a NaN or Inf popped out, namely signal an error.”.

Fourth Of July Party Ideas For Kids: Food They’ll Love

By Dee Power

Fourth of July marks the high point of summer but sometimes kids get left out of the party because there’s only grownup food around. Here are a few food ideas that are sure to please your little ones.

Children love bite size snacks they can carry with them. Just about every child loves macaroni and cheese. You can make it special and portable by hollowing out a small dinner roll and stuffing it with mac and cheese. They won’t even need a spoon.

Stuff cherry tomatoes with a mixture of one cup of cottage cheese mixed with one quarter cup of parmesan cheese. Fill a plastic disposable container large enough to serve the stuffed tomatoes, half full of water, then freeze at least overnight. At party time serve the tomatoes on the lid of the container placed on the ice.

For a variation stuff the tomatoes with chicken salad or tuna salad.

Chicken wings are fun and easy. Cut a chicken wing in three pieces. Save the bony wing end for making chicken broth. Bake the wings at 350 degrees until done. Serve at room temperature with dipping sauces. Mix equal parts honey, lime juice and mustard for a tangy dip. Or try equal party ketchup and brown sugar for a BBQ like sauce. Each child gets their own little cup of dipping sauce.

Miniature hotdogs and buns are always a hit. Buy the little franks and refrigerator biscuits. Cut the biscuits in half. Place one little frank in the center and roll up. Bake as package directs.

Grill baby burgers and place in a cut dinner roll, top with a slice of tomato, a lettuce leaf, and favorite condiments like mayonnaise, ketchup, and mustard..

Salad to go. Wash endive leaves. Fill the broad end with a teaspoon of your kid’s favorite prepared salad. Wash butter lettuce leaves, selecting the smaller more pliable leaves. Spread out the lettuce leaf and put a tablespoon of salad on the end nearest you. Roll the leaf forward covering the salad. Tuck the ends of the leave under as if you were rolling up a burrito. Lightly fill celery stalk with cream cheese. Press dried cranberries or raisins into the cheese. Cut into child bite sized pieces. For a change use flavored cream cheese.

Child sized pizzas. Use refrigerator biscuits. Lightly flour a board. Roll each biscuit flat doubling the size of the biscuit. Place biscuits on cookie sheets. Spread with a teaspoon of tomato sauce, pizza sauce or spaghetti sauce. An alternative is to use a slice of fresh tomato. Top with mozzarella cheese. Bake as package directs.

A veggie platter and dip can be made special by using baby vegetables. Carrots, summer squash, patty pan squash, string beans, both yellow and green should be blanched by immersing in boiling water for one minute and then in immediately in an ice bath. Add snap pea pods, grape tomatoes, both red and yellow, and boiled baby potatoes.

Mini tacos are fun and easy. Use the corn chips that are made for dipping and have a bowl shape. Fill with a teaspoon of cooked taco meat, a bit of refried beans and top with shredded cheese. Bake until the cheese just melts.

Usually the challenge with kids and desserts is to stop the kids from only eating the sweet stuff. Here are a few suggestions to carry the mini theme forward. Use small cookies like vanilla snaps or mini chocolate chips cookies. Place a tablespoon of ice cream on the flat side of one cookie and cover with the flat side of another cookie to make a sandwich then freeze in a plastic container.

Use a medium size sugar cookie, about a 3 inch diameter. Frost with vanilla pudding and top with slices of fresh strawberries for a mini strawberry tartlet. Make different varieties: Use chocolate pudding and raspberries, lemon pudding and fresh blueberries.

Children will love you for making them feel special at your Fourth of July party.

Magnitude 5.8 earthquake in Virginia felt up and down U.S. east coast, Pentagon evacuated

Tuesday, August 23, 2011

Shakemap of the quake Image: USGS.

A 5.8 earthquake struck 4 miles southwest of Mineral, Virginia, 80 miles south of Washington D.C., at 1:51 p.m. EDT (17:51 UTC) and lasted for 15–30 seconds. The quake had a magnitude of 5.8 with an epicenter 27 miles (43 km) east of Charlottesville, Virginia. A 2.8 aftershock was reported at 2:46 pm EDT (18:46 UTC).

According to Twitter reports, the quake was felt inland as far as Cleveland and Toronto and along the coast from Boston to Georgia. Police sergeant James Ryan, from South Brunswick, New Jersey stated that “The 911 line is flooding with calls right now. People want to know what happened. They want to know if there was an explosion.”

The United States Capitol and The Pentagon in Arlington were evacuated, as were police headquarters and city hall in New York City. Numerous minor injuries have been reported in Washington, D.C.; however, none of them are serious. There have been confirmed reports of damage at the Washington National Cathedral and the Smithsonian Castle. The Pentagon was also damaged when a burst pipe caused flooding. The North Anna Power Station lost offsite power and had to shut down, turning to four diesel generators to maintain cooling of the facility. Both the JFK and Newark airports were briefly shut down and the control towers were evacuated. A release from Amtrak stated that trains will be operating at reduced speed, but no damage has been found on any rail lines. The Washington Metro is also operating on reduced speed, with some stations closed down, while lines are evaluated.

In Boston, it was reported that the building at 111 Devonshire Street appeared to be leaning onto the adjacent building at 50 Milk Street, with fears that it could collapse. The street was blocked off while the Boston Fire Department investigated. However, it was determined that the buildings had always appeared like that. Nevertheless, the Boston Fire Department investigated the roof and the inside of 111 Devonshire St. After 30 minutes, the building was determined to be safe.

This is the second strongest earthquake to originate in Virginia since records have been kept, after the one recorded on May 31, 1897, near Giles County, which was estimated at a magnitude of 5.9.

The Dow initially dropped 50 points after the earthquake struck, but later increased over 100 points.

Report reveals Top 10 most-confusing tech buzzwords

Sunday, March 27, 2005

Danville, California — The California-based Engligh language tracker, Global Language Monitor, released its 2005 list of most confusing – yet frequently cited – high tech buzzwords to be “HTTP,” “Voice Over IP” (VoIP), and “Megapixel.” Closely following were “Plasma,” “Robust,” “WORM” and “Emoticon.”

In early March, the group used a predictive index computer algorithm to track specific words and phrases in the media and on the Internet. They were tracked in relation to frequency, contextual usage and appearance in global media outlets.

The Global Language Monitor claims to analyze and catalogue trends in word usage and word choices, focusing on the linguistic impact on various cultures. The GLM says it relies upon a global network of volunteer linguists, professional wordsmiths and other bibliophiles to monitor the trends in the evolution and demise of world languages.

GLM’s list, in order of frequency of use, of the most-confusing technology terms with the group’s explanation as to why they are faulty follows:

  1. HTTP – HyperText Transfer Protocol is the standard protocol used for transmitting web pages (which are written in HTML (HyperText Markup Language)), not text written while hyper on too much Starbucks coffee. There are more than 1 billion references to HTTP on the web alone.
  2. Voice over IP – Voice over Internet Protocol, (pronounced voyp, similar to Detroit) is a way of transmitting voice data over the Internet. VoIP is becoming more popular as services such as Skype offer people free voice communication with anyone with a broad-band connection.
  3. Megapixel – Approximately one million pixels, not a single, big pixel (“mega” is the metric system prefix for million). “Pixel” itself is a technical term which means “picture element”. Digital pictures consist of a grid of millions of pixels, which are square or rectangular dots, each having a single colour.
  4. Plasma – A plasma display (commonly used in televisions) is a flat, lightweight surface with a grid of millions of tiny glass bubbles containing plasma. A digitally controlled electric current flows through the bubbles causing the plasma inside to glow various colours. Plasma displays have nothing to do with blood plasma.
  5. Robust – Robustness generally means “it won’t break easily.” It supposedly describes computer programs or hardware that have been well-tested and demonstrated to not crash or fail often, but since it is a vague term by nature (how robust is robust?) it is frequently used by marketing types regardless.
  6. WORM – While a worm is a type of computer virus, WORM stands for ’Write Once, Read Many’. It describes a file system primarily used for optical disks, such as CDs and DVDs. For example, CD-Rs can only be written (or “burned”) once but afterwards can be read many times (otherwise you could only listen to your music CD once). This excludes re-writable CDs which can be written many times.
  7. Emoticon – Emoticon stands for emotional icon. An emoticon is a sequence of characters that look visually like a face and are used in text chat to convey emotion. The most common emoticon is the smiley face – 🙂 – which looks like two eyes and a mouth turned 90 degrees.
  8. Best of Breed – Not to be confused with the Westminster Dog Show, a best-of-breed product is a personalized solution made of components from various manufacturers; in other words, it’s a sort of high tech ‘mix-and-match’.
  9. Viral Marketing – A recent marketing trend which relies on word-of-mouth to spread, rather than traditional advertising strategies. It is called “viral” because as people talk about it, the marketing message “spreads” to new people, who in turn inform others, and so on, which is how viruses spread. The Burger King “Subservient Chicken” campaign is considered an example of viral marketing. Computer viruses used by spammers to turn desktop computers into “zombie” spam relays are something completely different.
  10. Data Migration – Data migration is an idealistic (though usually impossible) concept where data can be used by different versions of the program in which it was created (newer or older). The migration (migration means “to move”) refers to the fact that the data is moved from one version (or program) to another without difficulty or loss of information. It is a subset of backward and forward compatibility.

Other terms being tracked included “client/server,” “solution,” “paradigm,” “backward compatible,” and the “STUN protocol.”

Television producer and owner of the anti-Scientology website www.xenutv.com (XenuTV), Mark Bunker, also known as Wise Beard Man, chatted online with Wikinews for nearly three hours. More than 120 people followed the interview live (many from Project Chanology), which makes this exclusive Wikinews interview our most attended IRC interview to date.

Bunker started XenuTV in 1999 and began to make videos that he provided for the Lisa McPherson Trust. Bunker has been a critic of the Church of Scientology since 1997.

In 2006, he won a Regional Emmy Award after he and KUSI-TV news reporter Lena Lewis produced a documentary news video on the issues with the United States – Mexico border with San Diego, California.

UK government loses personal information of 25 million people

Tuesday, November 20, 2007

British Chancellor of the Exchequer Alistair Darling announced to a shocked House of Commons today that two password-protected — but not encrypted — computer disks containing the entire Child Benefit database have been lost in transit between the offices of Her Majesty’s Revenue and Customs (HMRC) in Washington, Tyne & Wear and the National Audit Office (NAO) in London, in what has been described as “one of the world’s biggest ID protection failures”.

The database contains details of all families in the UK who receive Child Benefit — all families with children up to 16 years of age, plus those with children up to 20 years old if they are in full-time education or training — estimated to contain 25 million individuals in 7.25 million families. Among other items of information, the database contains names, addresses, dates of birth, child benefit and National Insurance numbers, and where appropriate, bank or building society account details.

The discs were created by a junior official at the HMRC in response to a request for information by the NAO, and were sent unregistered and unrecorded on 18 October using the courier company TNT — which operates the HMRC’s internal mail system. When it was found that the discs had not arrived for audit at the NAO, a further copy of this data was made and sent — this time by registered mail — and this package did arrive. HMRC were not informed that the original discs had been lost until 8 November, and Darling himself was informed on 10 November.

The violation of data protection laws involved in the creation of the discs has led to strong attacks on the government’s competence to establish the proposed National Identity Register, when all UK residents will have an identity card. Conservative Shadow Chancellor George Osborne described the loss of data as “catastrophic” and said “They [the government] simply cannot be trusted with people’s personal information”.

The Chairman of HMRC, Paul Gray, has resigned over the affair, and critics are calling for Darling to do likewise.

This is the third data embarrassment for HMRC in recent weeks — earlier this month it was reported that the details of over 15,000 Standard Life customers had been put on disk, and then lost en route from HMRC in Newcastle to Standard Life in Edinburgh — and last month a laptop containing the data of 400 people with high-value ISAs was stolen from the boot of a car belonging to a HMRC official who had been carrying out a routine audit.

Bank of England governor warns housing market is biggest threat to UK economy

Sunday, May 18, 2014

The governor of the Bank of England, Mark Carney, has warned that the state of the housing market in the United Kingdom is the current biggest domestic threat to the country’s economy, due to lack of house building, and regulatory issues.

In an interview to be aired on Sky News today, he said the housing market is the “biggest risk” to the economy and has “deep, deep structural problems”. Of house building he said: “There are not sufficient houses built in the UK. To go back to Canada, there are half as many people in Canada as in the UK, twice as many houses are built every year in Canada as in the UK and we can’t influence that.”

“We’re not going to build a single house at the Bank of England. We can’t influence that. What we can influence […] is whether the banks are strong enough. Do they have enough capital against risk in the housing market?”

Carney also said the Bank of England would look into the procedures used to issue loans and mortgages to see if they were being granted appropriately: “We’d be concerned if there was a rapid increase in high loan-to-value mortgages across the banks. We’ve seen that creeping up and it’s something we’re watching closely.”

Kris Hopkins responded to Carney on behalf of the government, saying the government “inherited a broken housing market, but our efforts to fix it are working”. “We’ve scrapped the failed top-down planning system, built over 170,000 affordable homes and released more surplus brownfield sites for new housing. We’ve also helped homebuyers get on the housing ladder, because if people can buy homes builders will build them. Housebuilding is now at its highest level since 2007 and climbing. Last year councils gave permission for almost 200,000 new homes under the locally-led planning system and more than 1,000 communities have swiftly taken up neighbourhood planning. It’s clear evidence the government’s long-term economic plan is working.”

Earlier this month, the Organisation for Economic Co-operation and Development called on the UK government to “tighten” access to the ‘Help to Buy’ scheme introduced by George Osborne and the coalition government in 2013. ‘Help to Buy’ has also recently been criticised by three former Chancellors of the Exchequer — the Conservatives Norman Lamont and Nigel Lawson, and former Labour Chancellor Alistair Darling. Darling said: “Unless supply can be increased substantially, we will exacerbate that situation with schemes like Help to Buy.”

Iranian International Master Dorsa Derakhshani discusses her chess career with Wikinews

Tuesday, April 14, 2020

In February 2017, the Iranian Chess Federation announced two teenage chess players, Dorsa Derakhshani and her younger brother Borna Derakhshani, were banned from representing the national team. The federation announced their decision although Dorsa Derakhshani had previously decided and informed the chess federation she did not wish to play for Iran.

Dorsa Derakhshani is currently 21 years old and holds the International Master (IM) as well as Woman Grand Master (WGM) titles. Her brother, Borna, plays for the English Federation and holds the FIDE Master title.

Dorsa Derakhshani was banned since she did not wear a hijab, an Islamic headscarf, while competing at the Tradewise Gibraltar Chess Festival in January 2017. Under the laws of Islamic Republic of Iran, hijab is a mandatory dress code. Her brother Borna Deraskhsani was banned for playing against Israeli Grand Master (GM) Alexander Huzman at the same tournament. Iran does not recognise the existence of Israel, and previously, Irani athletes have avoided playing against Israeli athletes.

Mehrdad Pahlavanzadeh, the president of the country’s chess federation, explained the decision to ban the players saying, “As a first step, these two will be denied entry to all tournaments taking place in Iran and in the name of Iran, they will no longer be allowed the opportunity to be present on the national team.” ((fa))Farsi language: ?????? ????? ?? ??? ??? ?? ??? ????? ?? ?? ???? ???????? ?? ?? ????? ? ?? ??? ????? ?????? ??????? ????? ??????? ? ???? ???? ???? ?? ??? ??? ?? ??????? ????. He further stated, “Unfortunately, something that should not have happened has happened and our national interest is paramount and we have reported this position to the Ministry of Sports.” ((fa))Farsi language: ????????? ?????? ?? ????? ????????? ?????? ??? ? ????? ??? ?? ?? ?? ???? ?????? ???? ? ?? ??? ???? ?? ?? ????? ???? ?? ????? ?????.

IM Dorsa Derakhshani, who currently studies at Saint Louis University in the United States and plays for the United States Chess Federation, discussed her chess career, time in Iran and the 2017 controversy, and her life in Saint Louis with a Wikinews correspondent.

Global markets plunge

Friday, October 10, 2008

Wall Street, the home of many U.S. stock exchanges Image: Urban.

Stock markets across the world have fallen sharply with several seeing the biggest drop in their history.

Asian markets saw the biggest sell-off. The Nikkei dropped 9.62% to reach a 20 year low. Japan also saw a collapse of a mid-size insurance company, Yamato Life Insurance Company, which declared bankruptcy. The Hang Seng, which was one of the few markets that was positive yesterday, fell 7.19%. Australia dropped by 8.4% and South Korea saw a 9% fall.

In Europe, markets dropped at the open with the FTSE losing 11%. They have recovered only sightly with all European markets losing more than 5%. The European sell off was more about the Asian lows then any specific news. European banks and financial institutes saw the most selling. Also, oil related companies saw large drops as an result of an expected decrease in oil consumption.

The U.S. markets opened lower with the Dow Jones Industrial Average falling below 8,000, before recovering slightly. President George W. Bush made an address on the economy and said markets were being “driven by uncertainty and fear.”

Oil has seen losses of more than US$6 in trading with the current price of a barrel of oil less than $80. This is a year low for oil. News also came out that OPEC will hold an emergency meeting on November 18 to discuss the falling price of oil.

Charities, such as Cats Protection, today said that they have lost much of their funds in collapsing banks. Cats Protection had a total of £11.2 million saved in the now-collapsed Kaupthing bank.

The British National Council for Voluntary Organisations said that 60 of its 6,500 have lost money due to the collapse of banks.

The Dow Jones Industrial Average fell to its lowest level in five years at 8,579.19, falling 679 points in one day. This, at 7.3%, is the eleventh largest percentage fall in the history of the index. The growth then continued, with the index being up over 150 points on the start of the day at one point.

The index, did however, recover, and as of 19:30 UTC was up 17.68 points, or 0.21%, pushing the index up to almost 8600.

Peter Cardillo, chief market economist at Avalon Partners, commented on these massive falls. “What we’ve seen here was one big margin call that just kept feeding on itself, so the opposite could happen. But you need a catalyst,” he said. “I’m more convinced now than ever that this market has made a bottom. The capitulation came when we breached 8,000,” he continued. “It doesn’t mean we can’t go back and revisit that level.”

The UK’s FTSE 100 index fell dramatically to close below 4000, in the index’s worst week in history. This is despite the fact that just a few days ago the index was above 5000, and the index peaked above 5500 in September.The FTSE 100 index has fallen by 41% this year.

Barclays Wealth analyst Henk Potts commented on this massive fall. “We are drowning in a sea of red numbers,” he claimed. “Investors are concerned about the exacerbation of the credit crunch and the gloomy forecasts for economic growth. The reality is that most investors have been spooked by the sheer pressure that the credit crunch is putting on the global economy.”

The Japanese Nikkei 225 has recorded it’s third biggest drop in history with a massive sell-off in the exchange that has resulted in USD 250 billion being knocked of the index’s value.

Toyota, which is the second largest carmaker in the world, fell by the largest amount in 21 years, while Elpida Memory, the world’s largest manufacturer of computer memory, dropped in value to a record low.

Masafumi Oshiden, a fund manager in Toyota commented on the drop.”It’s capitulation,” he said. “There are lots of forced sellers. If you’re a fund that’s going bust you need to close out all your positions.”

George Bush speaking on the economy earlier today Image: White House.

George W. Bush commented on the financial situation earlier today. “Over the past few days, we have witnessed a startling drop in the stock market — much of it driven by uncertainty and fear,” he said. “This has been a deeply unsettling period for the American people. Many of our citizens have serious concerns about their retirement accounts, their investments, and their economic well-being.”

Bush then continued by promoting the government’s plan’s to get through the crises. “Here’s what the American people need to know: that the United States government is acting; we will continue to act to resolve this crisis and restore stability to our markets. We are a prosperous nation with immense resources and a wide range of tools at our disposal. We’re using these tools aggressively.”

Gordon Brown: We can not solve problems in the economy by improving liquidity Image: International Monetary Fund.

Gordon Brown, the UK Prime Minister, also spoke on the economy. “I think we quickly realised that we cannot solve the problems we have got as a result of the sub-prime market collapse simply by improving liquidity,” he said speaking in Birmingham to business leaders earlier today. “That would simply not be enough to deal with the bigger problem of rebuilding the banking system for the future and restoring trust is a fundamental element of that.”

Jim Flaherty Image: Joshua Sherurcij.

Jim Flaherty, the Canadian minister for finance, also commented today on the recent incidents in the economy. “It is important to underline that Canada’s banks and other financial institutions are sound, well capitalized and less leveraged than their international peers,” he claimed. “Our mortgage system is sound. Canadian households have smaller mortgages relative both to the value of their homes and to their disposable incomes than in the U.S.”

“”However, it is becoming increasingly clear that the continuing disruption of global credit markets, which has been severe and protracted, is making it difficult for our financial institutions to raise long-term funding. This is beginning to affect the availability of mortgage loans and other types of credit in Canada,” he continued. “The Government has therefore decided to act to address the current scarcity of private sector lending to Canadian mortgage markets and lending markets overall. This is going to make loans and mortgages more available and more affordable for ordinary Canadians and businesses.”

    Cleveland, Ohio clinic performs US’s first face transplant

    Thursday, December 18, 2008

    A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

    The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

    The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

    Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

    Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

    Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

    The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

    In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

    Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

    Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

    According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

    Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

    In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

    In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.
