SMS gateways you can use to get around high texting charges

business, cool stuff, tech help / By / 21 November 2009

Tired of high SMS charges? Use these SMS gateways, which translate emails & IMs into SMS text messages … for free (well, to the sender, anyway – the recipient still has to pay). And when recipients reply, those replies come back to the sender in the same format; in other words, you email someone, they receive a text, they reply, & you get it back as an email.

One more caveat: you obviously have to know which carrier people are using in order to send them a text message, so ask.

Programmer jokes

cool stuff, language & literature / By / 30 October 2009

Q: How do you tell an introverted computer scientist from an extroverted computer scientist?

A: An extroverted computer scientist looks at your shoes when he talks to you.

Knock, knock.

Who’s there?

very long pause….

Java.

Saying that Java is nice because it works on every OS is like saying that anal sex is nice because it works on every gender.

A physicist, an engineer and a programmer were in a car driving over a steep alpine pass when the brakes failed. The car was getting faster and faster, they were struggling to get round the corners and once or twice only the feeble crash barrier saved them from crashing down the side of the mountain. They were sure they were all going to die, when suddenly they spotted an escape lane. They pulled into the escape lane, and came safely to a halt.

The physicist said “We need to model the friction in the brake pads and the resultant temperature rise, see if we can work out why they failed”.

The engineer said “I think I’ve got a few spanners in the back. I’ll take a look and see if I can work out what’s wrong”.

The programmer said “Why don’t we get going again and see if it’s reproducible?”

To understand what recursion is you must first understand recursion.

Add houseplants to your home & office

cool stuff, science / By / 4 March 2009

From David Pogue’s “TED’s Greatest Hits” (The New York Times: 10 February 2009):

Kamal Meattle reported the results of his efforts to fill an office building with plants, in an effort to reduce headache, asthma, and other productivity-sapping aliments in thickly polluted India. After researching NASA documents, he concluded that a set of three particular common, waist-high houseplants—areca palm, Mother-in-Law’s Tongue, and Money Plant—could be combined to scrub the air of carbon dioxide, formaldehyde and other pollutants.

At about four plants per occupant (1200 plants in all), the building’s air freshened considerably, and the health and productivity results were staggering. Eye irritation dropped by 52 percent, lower respiratory symptoms by 34 percent, headaches by 24 percent and asthma by 9 percent. There were fewer sick days, employee productivity increased, and energy costs dropped by 15 percent.

The color of the TV you watch determines the color of your dreams

cool stuff, science / By / 12 February 2009

From Richard Alleyne’s “Black and white TV generation have monochrome dreams” (The Telegraph: 17 October 2008):

New research suggests that the type of television you watched as a child has a profound effect on the colour of your dreams.

While almost all under 25s dream in colour, thousands of over 55s, all of whom were brought up with black and white sets, often dream in monchrome – even now.

…

Research from 1915 through to the 1950s suggested that the vast majority of dreams are in black and white but the tide turned in the sixties, and later results suggested that up to 83 per cent of dreams contain some colour.

Since this period also marked the transition between black-and-white film and TV and widespread Technicolor, an obvious explanation was that the media had been priming the subjects’ dreams.

The Piraha language of Brazil

cool stuff, language & literature, writing ideas / By / 13 July 2006

From Wikipedia’s “Pirahã language“:

The Pirahã language is a language spoken by the Pirahã – an indigenous people of Amazonas, Brazil, who live along the Maici river, a tributary of the Amazon.

Pirahã is believed to be the only surviving member of the Mura language family, all other members having become extinct in the last few centuries. It is therefore a language isolate, without any known connection to other languages. Despite having only ~150 speakers as of 2004, in eight villages along the Maici, it is not itself in immediate danger of extinction, as language use is vigorous and the Pirahã community is monolingual. …

Unusual features of Pirahã include:

  • One of the smallest phoneme inventories of any known language [13]…, and a correspondingly high degree of allophonic variation, including two very rare sounds …
  • The pronunciation of several phonemes depends on the speaker’s sex.
  • An extremely limited clause structure.
  • No grammatical numerals, not even “one” or “two”; the closest the language comes to numerals are general quantity words like [“a few”, “some”, and “many”].
  • No abstract color words other than terms for light and dark.
  • Few specific kin terms; one word covers both “father” and “mother” [and they appear not to keep track of relationships any more distant than biological siblings.]
  • The entire set of personal pronouns appears to have been borrowed from Nheengatu, the Tupi-based lingua franca. Although there is no documentation of a prior stage of Pirahã, the close resemblance of the Pirahã pronouns to those of Nheengatu makes any other hypothesis improbable.
  • Pirahã can be whistled, hummed, or encoded in music.

The occurrence of so many unusual linguistic features in a single language is remarkable.

Camouflaged weapons

cool stuff, security, tech in changing society / By / 11 July 2006

From Noah Shachtman’s “Chameleon Weapons Defy Detection” (Defense Tech: 27 March 2006):

Last week I talked to Anthony Taylor, managing partner of an outfit which makes weapons which can be hidden in plain sight. You can be looking right at one without realizing what it is.

One type is the exact size and shape of a credit card, except that two of the edges are lethally sharp. It’s made of G10 laminate, an ultra-hard material normally employed for circuit boards. You need a diamond file to get an edge on it.

Taylor suggests that the card could easily be camouflaged as an ID card or one of the many other bits of plastic that clutter up the average wallet. Each weapon is individually handmade so they can be tailored to the user’s requirements.

Another configuration is a stabbing weapon which is indistinguishable from a pen. This one is made from melamine fiber, and can sit snugly inside a Bic casing. You would only find out it was not the real thing if you tried to write with it. It’s sharpened with a blade edge at the tip which Defense Review describes as “scary sharp.” …

According to one gun magazine, the CIA has had a ceramic handgun firing caseless non-metallic ammo for years.

How to travel to the most isolated human settlement on earth

commonplace book, cool stuff / By / 3 June 2006

From Adam Goodheart’s “The Last Island of the Savages” (The American Scholar, Autumn 2000, 69(4):13-44):

This is how you get to the most isolated human settlement on earth [North Sentinel Island, in the Andaman Islands]: You board an evening flight at JFK for Heathrow, Air India 112, a plane full of elegant sari-clad women, London-bound businessmen, hippie backpackers. You settle in to watch a movie (a romantic comedy in which Harrison Ford and Anne Heche get stranded on a desert island) and after a quick nap you are in London.

Then you catch another plane. You read yesterday’s Times while flying above the corrugated gullies of eastern Turkey, watch a Hindi musical somewhere over Iran. That night, and for the week that follows, you are in New Delhi, where the smog lies on the ground like mustard gas, and where one day you see an elephant – an elephant! – in the midst of downtown traffic.

From New Delhi you go by train to Calcutta, where you must wait for a ship. And you must wait for a ticket. There are endless lines at the shipping company office, and jostling, and passing back and forth of black-and-white photographs in triplicate and hundred-rupee notes and stacks of documents interleaved with Sapphire brand carbon paper. Next you are on the ship, a big Polish-built steamer crawling with cockroaches. The steamer passes all manner of scenery: slim and fragile riverboats like craft from a pharaoh’s tomb; broad-beamed, lateen-rigged Homeric merchantmen. You watch the sun set into the Bay of Bengal, play cards with some Swedish backpackers, and take in the shipboard video programming, which consists of the complete works of Macaulay Culkin, subtitled in Arabic. On the morning of the sixth day your ship sails into a wide, sheltered bay – steaming jungles off the port bow, a taxi-crowded jetty to starboard – and you have arrived in the Andamans, at Port Blair.

In Port Blair you board a bus, finding a seat beneath a wall-mounted loudspeaker blaring a Hindi cover of “The Macarena Song.” The bus rumbles through the bustling market town, past barefoot men peddling betel nut, past a billboard for the local computer-training school (“I want to become the 21st century’s computer professional”). On the western outskirts you see a sawmill that is turning the Andaman forests into pencils on behalf of a company in Madras, and you see the airport, where workmen are busy extending the runway – out into a field where water buffalo graze – so that in a few years, big jetliners will be able to land here, bringing tour groups direct from Bangkok and Singapore A little farther on, you pass rice paddies, and patches of jungle, and the Water Sports Training Centre, and thatched huts, and family-planning posters, and satellite dishes craning skyward.

And then, within an hour’s time, you are at the ocean again, and on a very clear day you will see [North Sentinel] island in the distance, a slight disturbance of the horizon.

Google’s number tricks

business, cool stuff, technology, weird / By / 19 January 2009

From “Fuzzy maths” (The Economist: 11 May 2006):

MATHEMATICALLY confident drivers stuck in the usual jam on highway 101 through Silicon Valley were recently able to pass time contemplating a billboard that read: “{first 10-digit prime found in consecutive digits of e}.com.” The number in question, 7427466391, is a sequence that starts at the 101st digit of e, a constant that is the base of the natural logarithm. The select few who worked this out and made it to the right website then encountered a “harder” riddle. Solving it led to another web page where they were finally invited to submit their curriculum vitae.

If a billboard can capture the soul of a company, this one did, because the anonymous advertiser was Google, whose main product is the world’s most popular internet search engine. With its presumptuous humour, its mathematical obsessions, its easy, arrogant belief that it is the natural home for geniuses, the billboard spoke of a company that thinks it has taken its rightful place as the leader of the technology industry, a position occupied for the past 15 years by Microsoft. …

To outsiders, however, googley-ness often implies audacious ambition, a missionary calling to improve the world and the equation of nerdiness with virtue.

The main symptom of this, prominently displayed on the billboard, is a deification of mathematics. Google constantly leaves numerical puns and riddles for those who care to look in the right places. When it filed the regulatory documents for its stockmarket listing in 2004, it said that it planned to raise $2,718,281,828, which is $e billion to the nearest dollar. A year later, it filed again to sell another batch of shares – precisely 14,159,265, which represents the first eight digits after the decimal in the number pi (3.14159265). …

Recover sounds from the ancient world

cool stuff, history, technology / By / 9 May 2006

From Christer Hamp’s “Archaeoacoustics“:

By archaeoacoustics I mean the recovery of sounds from the time before the invention of recording. This implies that such sounds would have been recorded inadvertently, while intending to do sometring else. Not much has been written about this subject and only very few experiments have been made, but I find the subject fascinating enough to dare the deep waters of the unproven and often scorned.

So far no ancient sound has been heard, and the experiments conducted have been attempts to reproduce the conditions at which such recordings would have been produced, successful attempts, according to the papers published.

What is probably the first publication on the subject appeared in 1969, when Richard G. Woodbridge, III related four experiments in a letter in the Proceedings of the IEEE1. In the first experiment, he could pick up the noise produced by the potter’s wheel from a pot, using a hand-held crystal cartridge (Astatic Corp. Model 2) with a wooden stylus, connected directly to a set of headphones. The second experiment yielded 60 Hz hum from the motor driving the potter’s wheel. More interesting were the following experiments, with a canvas being painted while exposed to sounds. In the third experiment the canvas was painted with a variety of different paints while exposed to martial music from loudspeakers. Some of the brush strokes had a striated appearance, and “short snatches of the music” could be indentified. For the fourth experiment, the painter spoke the word “blue” during a stroke of the brush, and after a long search the word could be heard again when stroking the canvas with the stylus.

A living story, tattooed on flesh

commonplace book, cool stuff, fiction, language & literature, on writing, weird / By / 1 April 2006

From The New York Times Magazine‘s “Skin Literature“:

Most artists spend their careers trying to create something that will live forever. But the writer Shelley Jackson is creating a work of literature that is intentionally and indisputably mortal. Jackson is publishing her latest short story by recruiting 2,095 people, each of whom will have one word of the story tattooed on his or her body. The story, titled ‘Skin,’ will appear only on the collective limbs, torsos and backsides of its participants. And decades from now, when the last of Jackson’s ‘words’ dies, so, too, will her tale.

As of November, Jackson, the Brooklyn-based author of a short-story collection called ‘The Melancholy of Anatomy,’ had enrolled about 1,800 volunteers, some from such distant countries as Argentina, Jordan, Thailand and Finland. Participants, who contact Jackson through her Web site, cannot choose which word they receive. And their tattoos must be inked in the font that Jackson has specified. But they do have some freedom to bend and stretch the narrative. They can select the place on their bodies they want to become part of the Jackson opus. In return, Jackson asks her ‘words’ to sign a 12-page release absolving her of liability and promising not to share the story with others. (Participants are the only people who will get to see the full text of the story.) They must also send her two photographs — one of the word on their skin, the other a portrait of themselves without the word visible — which she may later publish or exhibit.

… Mothers and daughters are requesting consecutive words. So are couples, perhaps hoping to form the syntactic equivalent of a civil union. For others, the motives are social: Jackson is encouraging her far-flung words to get to know each other via e-mail, telephone, even in person. (Imagine the possibilities. A sentence getting together for dinner. A paragraph having a party.) …

… when a participant meets his or her demise, Jackson vows, she will try to attend that person’s funeral. But the 41-year-old author understands that some of her 2,095 collaborators, many of whom are in their 20’s, might outlive her. If she dies first, she says, she hopes several of them will come to her funeral and make her the first writer ever to be mourned by her words.

Pi to unfathomable places

cool stuff, science / By / 4 March 2006

From “Man recites pi from memory to 83,431 places“:

A Japanese psychiatric counselor has recited pi to 83,431 decimal places from memory, breaking his own personal best of 54,000 digits and setting an unofficial world record, a media report said Saturday.

Akira Haraguchi, 59, had begun his attempt to recall the value of pi – a mathematical value that has an infinite number of decimal places – at a public hall in Chiba city, east of Tokyo, on Friday morning and appeared to give up by noon after only reaching 16,000 decimal places, the Tokyo Shimbun said on its Web site.

But a determined Haraguchi started anew and had broken his old record on Friday evening, about 11 hours after first sitting down to his task, the paper said. …

Pi, usually given as an abbreviated 3.14, is the ratio of the circumference to the diameter of a circle. The number has fascinated and confounded mathematicians for centuries.

Aided by a supercomputer, a University of Tokyo mathematician set the world record for figuring out pi to 1.24 trillion decimal places in 2002.

Robot on the run

cool stuff, science, technology / By / 29 November 2005

From The Age:

Scientists running a pioneering experiment with “living robots” which think for themselves said they were amazed to find one escaping from the centre where it “lives”.

The small unit, called Gaak, was one of 12 taking part in a “survival of the fittest” test at the Magna science centre in Rotherham, South Yorkshire, which has been running since March.

Gaak made its bid for freedom yesterday after it had been taken out of the arena where hundreds of visitors watch the machines learning as they do daily battle for minor repairs.

Professor Noel Sharkey said he turned his back on the drone and returned 15 minutes later to find it had forced its way out of the small make-shift paddock it was being kept in.

He later found it had travelled down an access slope, through the front door of the centre and was eventually discovered at the main entrance to the car park when a visitor nearly flattened it with his car. …

And he added: “But there’s no need to worry, as although they can escape they are perfectly harmless and won’t be taking over just yet.”

Sleazy books

cool stuff, history, language & literature / By / 21 January 2011

From sleazy and how!:

I’m a sucker for a sleazy mystery or a trampy romance novel from the 1950’s-60’s. I usually buy these silly books more for the covers than the stories, but sometimes both are equally bizarre.

This is a gallery of some of the better books I’ve come across. Some have book summaries, others I just liked the covers.

Passion Prize Here are some of the ones I liked: Women’s Doctor. Chinese Lover. Come Sin With Me. Studio Apartment. Musk, Hashish and Blood.

Frenchie, with this exciting passage: “He was all ready to go. The easel was under one arm. Suddenly she couldn’t think about what she should have done. There was no right or wrong way to act, there was only one way. She ran to him and pulled him down toward her. Her fingers bit into his arms. ‘No, no,’ she murmured brokenly. ‘You mustn’t go. You can’t. I couldn’t live…'”.

Illicit Desires, which includes this blurb: “Passion’s Slaves! There’s many a sizzling tale about the ‘farmer’s daughter’, but never has the truth been told so revealingly as in this story of Eva, a member of ‘Ja-Ja” Steinhart’s household; of Mazie, her buxom, full bosomed rival, and their spirited fight for their mutual lover, Joe.”

And Call Her Wanton (“She was fair…she was frisky…she was oh, so much fun…A lusty novel of wilderness passion and a wife too naughty to be true!”).

Or The Manatee (“He had a passion for his ship’s figurehead that no living, breathing woman could satisfy.”).

I think the prize for blurb writing goes to Shady Lady: “Some people called Leslie Fentris a shady lady and most people thought that was putting it mildly. She had money and brains, and plenty of lure. Yet she was mixed up in one shameful scandal after another. Actually, she was a fine and honest person who acted the way she did for very good reasons.

The mystery of the Voynich mss

commonplace book, cool stuff, history, language & literature, security / By / 21 January 2011

From John Baez:

A page from the Voynich mssThe Voynich manuscript is by far the most mysterious of all texts. It is seven by ten inches in size, and about 200 pages long. It is made of soft, light-brown vellum. It is written in a flowing cursive script in alphabet that has never been seen elsewhere. Nobody knows what it means. During World War II some of the top military code-breakers in America tried to decipher it, but failed. A professor at the University of Pennsylvania seems to have gone insane trying to figure it out. Though the manuscript was found in Italy, statistical analyses show the text is completely different in character from any European language.

More proof of time travel?

commonplace book, cool stuff, science, weird / By / 28 November 2005

From Ohio.com:

It was 11:15 p.m. on a warm June night in 1950, and the area of Times Square was buzzing with people leaving the theaters.

Suddenly, in the midst of traffic appeared an odd-looking man, about 30 years old. He wore mutton-chop whiskers and quaint clothing that had gone out of style decades before.

The man gawked at his surroundings, and then tried to dash away from the cars. He was struck by a cab and killed.

Police found on the dead man antique currency, business cards in the name of Rudolph Fentz, and a letter addressed to Fentz postmarked in 1876.

Assuming the man was Fentz, police sought the next of kin. But Fentz wasn’t listed in the telephone directory, and no one at the address on the business card and letter knew him.

Capt. Hubert V. Rihm eventually turned up a 1939 phone book listing a Rudolph Fentz Jr. When Rihm located the junior’s widow, she told him her father-in-law had vanished in 1876 after going out for a smoke.

That knowledge in hand, Rihm dug into old police files and found the missing-person report from 1876. The address given was the same as that on the dead man’s business cards.

Time travelers on the NYC subway

commonplace book, cool stuff, science, weird / By / 28 November 2005

From Making Light:

The funny thing is, I’ve seen time travellers in NYC. Or at any rate I’ve seen people I thought were time travellers, and one case where I was sure.

This happened one day back in the 1980s. I was riding the subway home from work, and this kid got on at 34th or 42nd. He was at most twelve but I think younger, and slightly built at that. What caught my eye first was that he was wearing a jacket with a waistline seam–not a full-blown norfolk jacket, less obtrusive than that, but in that class. Which was odd; it had been over half a century since boys’ and men’s jackets stopped having waistline seams.

I started noticing more things about him. His pants ended just below his knees. That was unobtrusive too; his pants were dark, and so were his long woolen socks. If you weren’t really looking, the combination would register as black trousers, and you wouldn’t think anything of it. He had a flat woolen cap, and a sweater on under the jacket, and his shoes were what you’d expect with the rest of the outfit. Think newsboy, turn of the century or a little later, and you’ve got it.

But what struck me as genuinely odd was that he wasn’t wearing his clothes like a costume. Those were just his clothes, and they weren’t new, either. I honestly believe that if he’d gotten onto the same subway in the same clothing but had felt like he was dressed up for a masquerade, half the car would have noticed him right away.

One of my favorite ideas: flow

commonplace book, cool stuff / By / 27 November 2005

From BrainChannels:

Mr. Csikszentmihalyi (pronounced chick-sent-me-high-ee) is chiefly renowned as the architect of the notion of flow in creativity; people enter a flow state when they are fully absorbed in activity during which they lose their sense of time and have feelings of great satisfaction. Mr. Csikszentmihalyi describes flow as “being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and you’re using your skills to the utmost.”
