Staying In Shape vs. a Busy IT Job Schedule? 865

Posted by timothy from the no-not-the-regular-hacker's-diet dept.
tnok85 writes "I started a new job ~7 months ago at a very large company working a 12-hour night shift (7PM-7AM) in a fairly high volume NOC. Our responsibilities extend during the night to basically cover everything but the most complex situations regarding UNIX/Windows/Linux/App administration, at which point we'll reach out to the on-calls. I live 1.5 hours away as well, so it turns into 4-5 15 hour days a week of sitting still — throw in almost an hour to get ready to leave, and a bit of time after I get home to unwind and I'm out of time to work out. Unfortunately I'm pretty sure I have a very slow metabolism, ever since I was a pre-teen I would gain weight fairly quickly if I didn't actively work out, regardless of how much or what I eat. (Barring starving myself, I suppose...) So, how does somebody who works a minimum of 60 hours over 4 days, often adding another 12 another day, and sometimes working 7-10 days straight like this, stay in shape? I can't hold a workout schedule, (which every person I've talked to in my history says is necessary to stay in shape) and I can't 'wake up early' or 'work out before bed' because I need sleep. Any thoughts/opinions/suggestions?"
Data Storage

Graphene Could Make Magnetic Memory 1000x Denser 123

Posted by ScuttleMonkey from the more-digital-sardines-in-the-tin dept.
KentuckyFC writes "The density of magnetic memory depends on the size of the magnetic domains used to store bits. The current state-of-the-art uses cobalt-based grains some 8nm across, each containing about 50,000 atoms. Materials scientists think they can shrink the grains to 15,000 atoms but any smaller than that and the crystal structure of the grains is lost. That's a problem because the cobalt has to be arranged in a hexagonal close packing structure to ensure the stability of its magnetic field. Otherwise the field can spontaneously reverse and the data is lost. Now a group of German physicists say they can trick a pair of cobalt atoms into thinking they are in a hexagonal close packing structure by bonding them to a hexagonal carbon ring such as graphene or benzene. That's handy because the magnetic field associated with cobalt dimers is calculated to be far more stable than the field in a cobalt grain. And graphene and benzene rings are only 0.5 nm across, a size that could allow an increase in memory density of three orders of magnitude."

Where Does a Geek Find a Social Life? 1354

Posted by kdawson from the meet-space dept.
JustShootMe writes "I have a question for my fellow Slashdotters, and yes, I realize I am entering the lion's den covered in tasty meat-flavored sauce. I have never been a very social person, preferring to throw myself into technology; therefore, I've been spectacularly unsuccessful in developing any meaningful interpersonal relationships. Lately I have begun to feel that this situation is not tenable, and I would like to fix it. But I really don't know how and haven't the faintest idea where to start. I know that I am in the minority and that there are many different kinds of Slashdot readers, most of whom have more experience in this realm than I do. So please tell me: how, and more importantly, where do you meet fellow geeks — preferably including some of the opposite gender — in meatspace?"

Passengers Cheat Flu Scan With Fever Reducers Screenshot-sm 299

Posted by samzenpus from the take-two-aspirin-and-infect-me-in-the-morning dept.
Nguyen Van Chau, head of Ho Chi Minh City's Health Department, has revealed that many sick passengers who flew to Ho Chi Minh City used fever reducers to fool temperature scanners at the airport. The government has confirmed 26 people infected with H1N1 flu, 23 of whom came by air after traveling in the United States or Australia. State media reports that the discovery of these scanner cheaters led to the detection of several infected cases later.

NASA To Trigger Massive Explosion On the Moon In Search of Ice 376

Posted by timothy from the smashing-darling-smashing dept.
Hugh Pickens writes "NASA is preparing to launch the Lunar Crater Observation and Sensing Satellite, which will fly a Centaur rocket booster into the moon, triggering a six-mile-high explosion that scientists hope will confirm whether water is frozen in the perpetual darkness of craters near the moon's south pole. If the spacecraft launches on schedule at 12:51 p.m. Wednesday, it will hit the moon in the early morning hours of October 8 after an 86-day Lunar Gravity-Assist, Lunar Return Orbit that will allow the spacecraft time to complete its two-month commissioning phase and conduct nearly a month of science data collection of polar crater measurements before colliding with the moon just 10 minutes behind the Centaur."

GPS Shoes For Alzheimer's Patients Screenshot-sm 116

Posted by samzenpus from the grandma-catching dept.
A shoe-maker, Aetrex Worldwide, and GTX Corp, a company that makes miniaturized Global Positioning Satellite tracking and location-transmitting devices, are teaming up to make shoes for people suffering from Alzheimer's Disease. "The technology will provide the location of the individual wearing the shoes within 9m (30 feet), anywhere on the planet. Sixty per cent of individuals afflicted with Alzheimer's Disease will be involved in a 'critical wandering incident' at least once during the progression of the disease — many more than once," said Andrew Carle, an assistant professor at George Mason University who served as an advisor on the project. Not only will this technology allow a caretaker to find a loved one with a click of a mouse, but the shoes are more humanizing than a bell hung around the neck.

Mozilla Preparing To Scrap Tabbed Browsing? 554

Posted by CmdrTaco from the if-it-ain't-broke-fix-it dept.
Barence writes "Mozilla Labs has launched a design competition that aims to find an alternative to tabbed browsing. 'Tabs worked well on slow machines on a thin internet, where ten browser sessions were "many browser sessions,"' Mozilla claims on its Design Challenge website. 'Today, 20+ parallel sessions are quite common; the browser is more of an operating system than a data display application; we use it to manage the web as a shared hard drive. However, if you have more than seven or eight tabs open they become pretty much useless.' Aza Raskin, the head of user experience at Mozilla Labs, has already blogged on the possibility of moving tabs down the side of the browser, with tabs grouped by the type of activity involved (i.e. applications, work spaces)."

Court Orders Breathalyzer Code Opened, Reveals Mess 707

Posted by timothy from the take-a-sober-look-at-this dept.
Death Metal writes with an excerpt from the website of defense attorney Evan Levow: "After two years of attempting to get the computer based source code for the Alcotest 7110 MKIII-C, defense counsel in State v. Chun were successful in obtaining the code, and had it analyzed by Base One Technologies, Inc. By making itself a party to the litigation after the oral arguments in April, Draeger subjected itself to the Supreme Court's directive that Draeger ultimately provide the source code to the defendants' software analysis house, Base One. ... Draeger reviewed the code, as well, through its software house, SysTest Labs, which agreed with Base One, that the patchwork code that makes up the 7110 is not written well, nor is it written to any defined coding standard. SysTest said, 'The Alcotest NJ3.11 source code appears to have evolved over numerous transitions and versioning, which is responsible for cyclomatic complexity.'" Bruce Schneier comments on the same report and neatly summarizes the take-away lesson: "'You can't look at our code because we don't want you to' simply isn't good enough."

Girl Who Named Pluto, At 11, Dies At 90 158

Posted by kdawson from the no-phair dept.
notthepainter notes the passing of the woman who, as an 11-year-old girl, named Pluto. "Frozen and lonely, Planet X circled the far reaches of the solar system awaiting discovery and a name. It got one thanks to an 11-year-old British girl named Venetia Burney, an enthusiast of the planets and classical myth. On March 14, 1930, the day newspapers reported that the long-suspected 'trans-Neptunian body' had been photographed for the first time, she proposed to her well-connected grandfather that it be named Pluto, after the Roman god of the underworld. Venetia Phair, as she became by marriage, died April 30 in her home in Banstead, in the county of Surrey, England. She was 90. ... More vexing to Mrs. Phair was the persistent notion that she had taken the name from the Disney character. 'It has now been satisfactorily proven that the dog was named after the planet, rather than the other way around,' she told the BBC. 'So, one is vindicated.' " Venetia's great-uncle Henry, who was a housemaster at Eton, had successfully proposed that the two dwarf moons of Mars be named Phobos and Deimos.

Mariners Develop High Tech Pirate Repellents 830

Posted by samzenpus from the scuttle-the-ship dept.
Hugh Pickens writes "NPR reports that owners of ships that ply the dangerous waters near Somalia are looking at options to repel pirates including slippery foam, lasers, electric fences, water cannons and high-intensity sound — almost anything except guns. One defense is the Force 80 squirt gun with a 3-inch nozzle that can send 1,400 gallons a minute 100 yards in any direction. 'It is a tremendous force of water that will knock over anything in its path and will also flood a pirate's ship very quickly,' says Roger Barrett James of the the Swedish company Unifire. Next is the Mobility Denial System, a slippery nontoxic foam that can be sprayed on just about any surface making it impossible to walk or climb even with the aid of a harness. The idea would be to spray the pirate's vessel as it approached, or to coat ropes, ladders, steps and the hull of the ship that's under attack. The Long Range Acoustic Device, or LRAD, a high-powered directional loudspeaker allows a ship to hail an approaching vessel more than a mile away. 'Knowing that they've lost the element of surprise is half the battle,' says Robert Putnam of American Technology Corp. The LRAD has another feature — a piercing "deterrent tone" that sounds a bit like a smoke detector alarm with enough intensity to cause extreme pain and even permanent hearing loss for anyone directly in the beam that comes from the device. But Capt. John Konrad, who blogs for the Web site Gcaptain.com, says no anti-pirate device is perfect. 'The best case scenario is that you find these vessels early enough that you can get a Navy ship detached to your location and let them handle the situation.'"

Sun Announces New MySQL, Michael Widenius Forks 306

Posted by CmdrTaco from the this-cracks-me-up dept.
viktor.91 writes "Sun Microsystems announced three new MySQL products: MySQL 5.4, MySQL Cluster 7.0 and MySQL Enterprise Partner Program for 'Remote DBA' service providers." which showed up in the firehose today next to Glyn Moody's submission where he writes "Michael Widenius, founder and original developer of MySQL, says that most of the leading coders for that project have either left Sun or will be leaving in the wake of Oracle's takeover. To ensure MySQL's survival, he wants to fork from the official version — using his company Monty Program Ab to create what he calls a MySQL "Fedora" project. This raises the larger question of who really owns a commercial open software application: the corporate copyright holders, or the community?"

This is not unique to Microsoft products. Databases have been doing this for a long time. Oracle Database has options for RAW devices and disk access, where redundancy is handled in the application layer by throwing more disks at the problem. You can also stack your layers of redundancy by using Oracle automated storage management to have multiple logical disks while at the same time using an array controller to provide a level of RAID redundancy at the physical layer.

And a point about JBOD being useful for Exchange. In most Exchange environments I have worked with, replication happens at the appication layer, with huge portions of the data store being replicated amongst members of the Exchange Cluster, each with their own copy of the data. While expensive RAID/physical redundancy is a good idea, it is not critical as exact copies of the data store are available elsewhere in the cluster, and mailboxes can be failed over to those members.

And for the people that want a full RDBMS or SQL Server under the hood of Exchange - this is primarily a performance concern. Exchange access to data stores has such a unique profile that ca be modeled to show specific performance profiles that would benefit from a customized data access layer, overall Exchange performance would be hampered by the inclusion of an RDBMS that was designed to respond to a multitude of performance profiles. When you have the luxury of understanding how your application accesses data, it is best to choose (or develop) the data storage subsystem that will reap you the best performance. Here is where I believe Microsoft has the right approach.
