Funny thing about this, actually.

I jumped on the dual-processor bandwagon pretty much the instant that commodity CPUs officially supported it. Namely, the Athlon MP. I got a Tyan Tiger motherboard and a friend did the same. Shortly thereafter I lost contact with that friend.

A few years later I went to turn on my computer as usual and it wouldn't turn on. A bit of troubleshooting later and I realized that the PSU connector had burned itself into the motherboard power socket because something on the motherboard had randomly decided to short itself. Four of the pins had fried (in a distinctive pattern, see here and here) and I ended up buying a new motherboard from a different manufacturer and a new power supply (thankfully, the other components had survived fine.)

About a year after that I ran into my friend. We were talking about upgrades and I dug out those pictures. Turned out he'd lost three Tyan Tiger motherboards, with the exact same burn pattern, before changing manufacturers.

So, yeah, I'm not touching Tyan again. I've never actually had a computer component burn itself to death before, and one time was enough.

Tied Up in Knots
Anything that can tangle up, will, including DNA

Davide Castelvecchi

Knotted threads secure buttons to shirts. Knots in ropes attach boats to piers. You can find knots in shoestrings, ties, ribbons, and bows. But even without Boy Scouts or sailors, knots would be everywhere.

Call it Murphy's Law of knots: If something can get tangled up, it will. "Anything that's long and flexible seems to somehow end up knotted," says Andrew Belmonte, an applied mathematician at Pennsylvania State University in University Park. Belmonte has plenty of alarming anecdotal evidence. "It certainly happens in my house, with the cords of the venetian blind." But the knot scourge is a global one, as anyone who owns a desktop computer can confirm after peeking at the mess of connection cables and power cords behind the desk.

Now, scientists think they may have found out how and why things find their way into knotty arrangements. By tumbling a string of rope inside a box, biophysicists Dorian Raymer and Douglas Smith have discovered that knots--even complex knots--form surprisingly fast and often. The string first coils up, and then its free ends swivel around the other coils, tracing a random path among them. That essentially makes the coils into a braid, producing knots, the scientists say.

The results' relevance may go well beyond explaining the epidemic of tangled venetian blind cords. That's because spontaneous knots seem to be prevalent in nature, especially in biological molecules. For example, knottiness may be crucial to the workings of certain proteins (see "Knots in Proteins"). And knots can randomly form in DNA, hampering duplication or gene expression--so much so that living cells deploy special knot-chopping enzymes.

Raymer's interest in knots began as an answer waiting for a question. Two years ago, he was an undergraduate student working in Smith's lab at the University of California, San Diego (UCSD). Raymer fancied taking a class about the abstract theory of knots, offered by UCSD's math department. Smith told him that he should take it only if he could find a practical use for it--some kind of knot experiment.

Raymer never took the class, but he and Smith did come up with a simple idea for an experiment. They put a string in a cubic container the size of a box of tissue. By tumbling the box 10 times "like a laundry dryer," as Raymer puts it, the researchers hoped to observe knots forming spontaneously on occasion. They didn't have to wait for long: Knots formed right away. "The first couple of times, it was pretty amazing," Raymer says.

The researchers repeated the procedure more than 3,000 times, and knots formed about every other time. Longer strings, or more-flexible strings, tended to knot more often.

The researchers took pictures, planning to gather precise statistics of the types of knots that were forming. Raymer soon realized that, to make sense of the mess, he'd need to teach himself the mathematics of knots after all.

Ready-made tools

The theory of knots began in earnest in the 1860s, under the stimulus of the British physicist William Thomson, later known as Lord Kelvin. Kelvin suggested that atoms of different elements were really different kinds of knotted vortices in the ether. So to lay the foundations of chemistry, he believed, it was imperative to classify knots. Ultimately, physicists discovered that the ether didn't exist. But mathematicians took an interest in knots for knots' sake, as part of the young branch of mathematics called topology.

Topology studies shapes. Specifically, it studies shapes' properties that are not affected by stretching, moving, twisting, or pulling--anything that doesn't break up the object or fuse some of its parts. The proverbial example is that, to a topologist, a coffee mug is the same as a doughnut. In your imagination,

There is an Australian fellow who has done a resonably thoughough analysis of the proposed Australian ban on incandescent bulbs.

It is worth a read, especially the section where he discusses inductive vs capacitive loads and the power factor of CFL's - Its not something I have heard discussed anywhere else but it's probably worth thinking about.

A map of coverage in Europe from *1997* has about 50% GSM coverage. A current map has pretty much 100% coverage.

The CIA factbook says the USA has 233M subscribers (2006), 301M people = 77%
The EU has 466M (2005), 490M people = 95%

She would now have a fully functional and automatic backup solution. If one of her computers ever crashed she just needs to boot to the supplied recovery CD and select which backup she wants to restore and in about 20 minutes her computer is up and running.

Getting your files online is also a piece of cake. If your router supports UPnP Windows Home Server will automatically configure it. All you have to do is choose the subdomain you want to use with the Microsoft provided homeserver.com TLD, everything is served right off your server.

Another cool feature of Windows Home Server is the way it handles storage. No matter how many physical drives you have in the server they all show up as one drive, even external storage functions the same way. This means you don't have to worry about managing multiple drives, where the data is stored, and you never have to worry about running out of space, just pop in another drive or add an external drive and WHS takes care of everything else. You can also choose to have your files duplicated, which puts them on more than one physical drive so that if one drive fails you don't loose your data. Also, the backups will never backup the same file twice, even if it is on more than one computer. If there are differences it only backs up the differences and on the cluster level so it is extremely efficient with storage space.

There is a ton more and you can read my review to see it all.

With all of the hype surrounding hybrid vehicles today, I thought I'd do some research and post my findings on the next generation of fully electric and plug-in hybrids. The fully-electric EV has had a bad name in the past, mostly due to insufficient battery technology, politics, lack of performance models and other factors. Starting this year with the Tesla Roadster, the EV is going to take on a new form in the eyes of John Q Public. Quiet, efficient EVs will start to become commonplace in the next few years as major manufacturers go into production with the newest generation of vehicle sporting more powerful motors, efficient generators and the latest battery technology.

The big change will be the introduction of full EVs and plug-in hybrids. Full EVs are as one would expect: A fully electric vehicle that uses no other fuels. A plug-in hybrid is a vehicle that uses electricity as its primary power source and is equipped with a generator that supplements electricity as-needed. Many of the plug-in hybrids have an electric-only range of 30-60 miles with an extended range of 400-700 miles. The difference to the consumer is the way in which the vehicle is charged. Traditional hybrids are powered primarily by gas and thus need to be refueled regularly. Plug-in hybrids plug in at home and to most people that means they park the car at home, plug it in overnight and it's ready to go the next morning. This means that if you're driving less than your EV range each day, you'll never need to put a drop of gas into the car. How nice does that sound?

The following table is a consolidation of data collected from many different sources, cited at the bottom of this article. It has many key points that the average person may be interested in. Much of the data is still not readily available due to the pre-production and concept status of some of the models. I will do my best to keep this chart up-to-date.

(Copy of the chart)

As you can see from the production dates, four out of six of the vehicles are scheduled to be in production in 2010 but the other two, the Tesla Roadster and Aptera are scheduled for production in 2008. Both companies are currently taking pre-orders. Estimated production numbers are difficult to find but Chevy has claimed 60,000 in the first year.

Performance is a hot issue with EVs and this generation is no doubt going to address that. I calculated a figure where applicable which divides the vehicles weight in pounds into its peak power rating. The resulting number gives an indication for how well the vehicle should be able to accelerate. While numbers are only available for a few cars, the Tesla Roadster easily takes the lead with a a 0-60 of 4 seconds and a 68.5 Watt/Pound ratio. This should prove to many that EVs are now capable of being mainstream performance cars.

Most of these plug-in hybrids are expected to have a 3-cylinder turbo diesel or gasoline generator which usually produces slightly more than the continuous power rating of the car. Translation: You can drive as far as you want with this car only refueling and not having to recharge. This alone should resolve many people's fears of range with EVs.

The Aptera is one of the most interesting vehicles here with its very aerodynamic, futuristic design and high range specifications. It comes in two models: Fully EV and Hybrid. The Full EV model is estimated to be $26,900 and the Hybrid at $29,900.

The Mitsubishi MiEV Sport is supposed to compete with the Tesla Roadster but currentl

Actually I am not new around here. I understand that it is possible to setup something similar to what Windows Home Sever (WHS) offers, but you almost have to have a degree in Computer Science to do it. I would be very comfortable telling my mom how to install Windows WHS because it is so easy. It really takes only 2 steps:

1. Put in the server install disk and answer very basic questions, the questions are so easy to answer that the recommended choices are already chosen and you could just hit next. You this step completely if you purchase a pre-built system, which most people will do.
2. Put the connector disk into each client computer and answer the questions.

I second that suggestion.

I just completed a very extensive review of both the hardware and software for Windows Home Server. It is a fantastic backup solution and you can build a machine for very little cost. Not only do you get a great backup solution, but you also get a lot more. Windows Home server has a built in web server that will host all your files online for free. From the website you can also Remote desktop into any of your Windows boxes that support remote desktop. You can also stream all your media content from the Home server to any machine on your network. There are some problems with the Media Streaming, hopefully those will be fixed. Last but not least you have the ability to use add-ins which can add tons of extra functionality.

The biggest limitation of Windows Home Server is that it will not backup anything but Windows machines, but that does not mean someone won't write an add-in that allows other operating systems to be backed up.

For example, Chicago's primary datacenter facility is in 350 E. Cermak (right next to McCormick Place) and the primary interconnect facility in that building is Equinix (which has the 5th and now 6th floors.) A year or so ago there was a major outage there (that mucked up a good amount of the internet in the midwest) when a power substation caught on fire and the Chicago Fire Department had to shut off power to the entire neighborhood. So the backup system started like it should, with the huge battery rooms powering everything (including the chillers) for a bit while the engineers started up the generators. Only thing is, the circuitry that controls the generators shorted out, so while the generators themselves were working, the UPS was working, the chillers were working, this one circuit board blew at the WRONG moment. And this isn't the only time this circuit has been used, they test the generators every few weeks.

Long story short, once the UPSes started running out of power the chillers started going, lights flickered, and for a VERY SHORT period of time the chillers went out before all of the servers did. Within a minute or two it got well over 100 degrees in that datacenter. Thank god the power cut out as quick as it did.

So yes, Equinix in that case did everything by the book. They had everything setup as you would set it up. It was no big deal. But something went wrong at the worst time for it to go wrong and all hell broke loose.

It could be worse, your datacenter could be hit by a tornado

Oh, and the error message gives us a chance to find his homepage, where he seems to log everything happening in his house. It looks like he flushes his toilet a lot, lately.

Well, I was able to RTFA before it was slashdotted, and in it he said his MySQL server already had trouble keeping track of all the data. Adding a slashdotting to the mix probably didn't do the poor server any good (he's probably hosting it himself on a PIII attached to a DSL line or something).

It's just plain irresponsible of the submitter not to use the Coral cache...

when in doubt, check for a mirrored version...typically, if you add ".nyud.net" to the hostname (or "fully qualified domain name", for the truly picky) of a slashdotted, dugg, or farked link, you'll get a cached version, if it's popular and had decent bandwidth at the beginning.
