Linux Read/Write NTFS driver

(via OSNews)

This is practically old news now, but the Linux NTFS team announced last Friday, July 14th, that a public release of the NTFS for Linux driver is now available.

Hello,

As part of the Linux-NTFS project, I’m happy to announce my contribution to ntfsmount and libntfs which resulted ntfs-3g, a read-write ntfs driver, capable for unlimited file creation and deletion.

The driver was successfully tested very exhaustively for a longer period of time by many ways and methods, creating and destroying millions of files and directories on newly created images, and on over 40 real, very diverse NTFS images collected over the last four years.

Simple tips to boost your Intarw3b speeds

Chris Pirillo shares a couple of easy to follow tips for improving network speeds on your computer.

  1. Open yourself to OpenDNS. They have configuration pages for your OS or hardware router. Both Scott Beale (LaughingSquid) and I have seen dramatic differences in speed since going through their DNS servers. Matt’s happy about it, too. My speed difference was probably even more dramatic, considering I’ve already implemented my second recommendation…
  2. If you’re on Windows, install FastCache: “Every time you go to a new website, or a website you haven’t been to in a day or so, your computer needs to locate the server again using DNS. Each DNS request can take anywhere from 50 milliseconds, to even a second or more, but most are in the 100 to 200 millisecond range. Want to save a couple hundred milliseconds? Probably not, but what about a couple million or more? That’s what AnalogX FastCache is all about.” I’ve been running FastCache since Mark released it on the first Helpathon. My stats are somewhat stunted, but I’ve saved 6d 18h 27m 53s worth of time (in 118w). It really adds up.

There you have it. Now hop to, and get that pr0n faster.

Octopus wrestling is my hobby

Modern Mechanix has some of the most interesting flash-back articles I’ve ever seen. The latest to catch my eye is an article from the April 1949 issue of Mechanix Illustrated. As indicated by this article’s title, the magazine article is called “Octopus wrestling is my hobby.” Even if I didn’t find the article fascinating, I’d probably have to post it just to use the awesome headline and the cool story cover page.

Here’s a new kind of deep-sea fisherman—he stalks the cunning, eight-armed king-of-the-ocean in the coral lagoons of the Pacific

By Wilmon Menard

“YOU have come to the right place, my son,” said the old man. “On this atoll, the world’s first octopuses were born—and will one day die, we pray!”

The wizened grandfather of my native guide greeted us with those words when we landed on the tropical beach at Rimaroa during our ocean-wide hunt for octopuses. For, as in ancient days, the Islanders still regard the giant octopus with awe.

They believe him to be the prowling ghost of the wicked god Tumuraifenua, who cast the natives into darkness by holding down the sky with his tentacles. According to the legend, sickness overwhelmed the population and slimy monsters crawled from the deep lagoons to devour entire villages. But for me, wrestling and killing the treacherous octopus was simply a hobby and I had crossed the Pacific to engage in this fascinating pastime.

. . .

Then, there would be a human-like moan and the water would be clouded with sepia. The long tentacles would flay the surface of the lagoon in savage fury, as the monster tried to rid itself of our spears which were firmly imbedded in its head. If necessary, another spear would be dispatched into the writhing hulk. It took a long time to tire the octopus and we had to hold firmly to the ropes attached to the end of the spears to prevent it from sinking to the bottom of the lagoon where it would be lost to us.

What did we do with the octopus after we killed it? We simply lashed it behind our outrigger canoe, towed it back to the village and presented it to the district chief. And what did the natives do with it? They ate it!

. . .

One day, in the late afternoon, Roo and I discovered a huge monster with 25-foot tentacles in a coral grotto just below the surface of the lagoon. We let out a cry for the natives of the village to assist us. This brute was just too big for two men to handle. With spears, knives and clubs, the entire village arrived to do battle with the giant octopus.

The monster, disturbed by the noise and sensing no escape from its attackers, lashed out menacingly with its long writhing tentacles. As quickly as the grisly arms rose above the surface of the lagoon, the natives slashed them off. In the darkness of the coral cavern, I could see the horrible purplish eyes.

Suddenly, one of the bolder assailants gave a warning shout. Being closer to the monster’s lair, he saw that it was emerging from its retreat to fight us in the open. As it rose to the surface, pulling itself up the reef wall by its partly-severed tentacles, I could see that it was of a reddish hue, with a hideous horned head. Then it started rolling toward us. Although its sepia secretion clouded the water during the first stages of the conflict, I could see that its tentacles were really 25-feet long. Partly cut off by the natives’ knives, they flayed the surface of the lagoon, groping out for the attackers.

. . .

Like to wrestle an octopus? I realize it all sounds like a loathsome sport but it’s really more fun than hunting some poor harmless creature. When you wrestle and kill an octopus, you’re ridding the marine world of a treacherous enemy.

And you’d better watch your step, too. For there’s no such thing as a reckless octopus hunter. You’re either careful or dead.

Read the full article for further details of the battle.

Turtleskin Snake Armor

Going someplace a bit off the beaten path?  You might just want some SnakeArmor.  Lightweight clothing with the strength to repel bites of large snakes like rattlesnakes, copperheads, and cottonmouths.  I don’t ever find myself in places where I would need this, but I imagine hunters and folks who work in the woods could use these.

TurtleSkin SnakeArmor’s patented technology produces the tightest weave ever made with high-strength fibers. Its weave is so tight, that snake fangs, briar, thorns, and cactus can’t slip past, while TurtleSkin’s ballistic fibers are so strong they resist breaking. This makes the fabric extremely protective while remaining lightweight and flexible. U.S. Patents 5,565,264 & 5,837,623 as well as other patents pending.

If this sounds like the kind of protection you need, hit their online store and buy to your heart’s content.

Superheated metal moves liquid uphill

I’ve been reading the latest issue of American Scientist in my spare time lately. A really cool article caught my eye, and I thought I’d pass it on for the more geeky, science-loving types in my audience. While I think half my readership isn’t into the science stuff I enjoy, I believe that other reader might be. For him, I pass along this cool story of liquid moving in the wrong direction.

SCIENCE OBSERVER
Going Against the Flow
Sometimes particles prefer to propel themselves uphill
Fenella Saunders

Particles strive for the life of a couch potato—sinking into a spot that has the least energy, where gravity can’t pull them down any farther and movement is at a minimum. Getting a particle moving requires keeping it off kilter, out of equilibrium. But particles in such a state tend to bounce all over; harnessing their movement in a single desired direction is the goal of many nanoscale devices.

One way to do this is with a ratchet effect—a mechanism that uses spatial asymmetry and energy gradients to make movement easier in one direction than another. It turns out that in some cases, ratchets not only control movement, but can also move particles in unexpected directions—away from a minimum energy state, the molecular equivalent of a creek climbing uphill under its own power.

. . .

If a skillet is heated to an extremely hot temperature, between 200 and 300 degrees Celsius, drops of water flicked into the pan will skitter across the surface, remaining intact for a minute or so. A surface not quite so hot will boil away the water droplets instantly, but the superheated surface instead instantly turns the bottom of the droplets into a layer of steam. Vapor is a poor heat conductor, so the steam insulates the drops from further boiling. It also provides them with a means of movement: The water drops bounce around like hovercraft on a cushion of air.

Linke and his colleagues did not use a smooth metal surface, but one covered with a sawtooth pattern. The teeth inclined more steeply in one direction than the other—an asymmetrical surface, and therefore a ratchet mechanism. Millimeter-sized water droplets piped onto the superheated sawtooth surface zip off in one direction like airport passengers on a moving walkway, reaching speeds of up to 5 centimeters per second, even if the surface is tilted so that the droplets have to climb uphill. As the investigators reported in the April 21 issue of Physical Review Letters, the phenomenon works for many other liquids, such as ethanol and liquid nitrogen, although the temperature at which the Leidenfrost effect kicks in varies from 50 to 150 degrees above the boiling temperature of the liquid.

More details on the science behind this in the full article. Also, access the full issue online, where many of the articles are freely readable. Some of the really juicy stuff requires membership ($28-$70 for 1-3 years in the US), but after reading a single issue, I’m considering a subscription.

Today in history – moon landing

In addition to being my older brother’s birthday, apparently humans first landed and walked on the moon today (assuming, of course, you discount any ancient alien races taking Egyptians to the moon, of course  🙂 ).  I meant to post this earlier today for edification of those who visit earlier in the day here, but I forgot.  Rather than steal more commentary from Wikipedia (which, in case you haven’t picked up on already, is one of my preferred sources for general information on a wide variety of subjects), I’m stealing details on the moon landing from the History channel today.

ARMSTRONG WALKS ON MOON:
July 20, 1969

At 10:56 p.m. EDT, American astronaut Neil Armstrong, 240,000 miles from Earth, speaks these words to more than a billion people listening at home: “That’s one small step for man, one giant leap for mankind.” Stepping off the lunar landing module Eagle, Armstrong became the first human to walk on the surface of the moon.

The American effort to send astronauts to the moon has its origins in a famous appeal President John F. Kennedy made to a special joint session of Congress on May 25, 1961: “I believe this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to Earth.” At the time, the United States was still trailing the Soviet Union in space developments, and Cold War-era America welcomed Kennedy’s bold proposal.

Compensate for your shortcomings

Ahhhh, another brilliant Worth1000 contest. This recently ended contest challenged photochoppers to make up fake ads for real products. Some of them just make me laugh too hard to function. For example, the following, advertising a product I’d like but will never get precisely because I think people view it as this ad shows:

RPU – Ray Tracing Processing Unit

(via Tingilinde)
I have no details on this beyond what the brief note at Tingilinde, but apparently the August 2006 issue of Scientific American has an introductory article to new ray tracing hardware.  The information in the article was part of a talk at SigGraph 2005.  Looks like I’ll need to head to the bookstore and pick up the magazine (or possibly get the digital edition).

Double-barrel cigarette holder

This brief article from the November 1931 issue of Modern Mechanix has the accessory every smoker needs:

Double-Barrel Cigarette Holder
We don’t know whether the cigarette manufacturers were behind this idea, but it might be a good idea for them to give away one of these new holders to all smokers. Just think how cigarette sales would jump if everybody smoked two at one time!
