A few trading firms have learned to have a second system that monitors transactions to keep tabs on profit and loss. If the things swing out of the expected range, it is time to have a human look at the situation. If things get really out of hand, it is time to rate limit transactions, or halt them out right. Sudden extreme profits usually indicates a data entry error on your system, not that the rest of the market has gotten really stupid.

Most inventory systems have a way to track cost of goods, age of inventory, and expected profit margin. Eventually retailers will start filling in those details, and tracking them, so they can notice when something goes expensively wrong.

It works even if my Nexus 5 is more than 5 mm above the charging pad. That is many orders of magnitude less than the range for most wireless communication technologies.

The useful features are

1. no connector to wear out,
2. alignment is simple.
3. The USB/thinport connector is available for other uses. (More of a theoretical benefit, as I don't use the USB port for anything, but I could if I wanted to. I've got the cable, I could even plug in an SD card reader.)

The error was an extra "m". The poster meant 0.14 Ohms per meter. I've seen higher resistance USB cable than that in the real world. Think of how much copper they saved by using such thin wires...

I was going to use the subject, Sort My Legos, but the prototype resolution is too low. With more actuators, you could dump Lego bricks on the table and have it sort them for you. Or for the more practical minded, sort wrenches, nuts and bolts.

I have a monitor hooked up to my ComCast cable box in the exercise room. After I exercised for a while, I would get the stupid HDCP warning and/or the video would just cut out. I switched cables, I switched HDMI - DVI adapters, I switched monitors. It seemed like every time I started exercising, the video would stop.

It got worse recently, making it easy to diagnose. It got to the point where the video went away within a second of starting the treadmill. It is an EMI issue. Either the treadmill is emitting too much, or the ComCast box's suicide circuit is too sensitive.

I am so pleased that my ComCast has a suicide circuit to protect me from evildoers who modify treadmills to steal valuable copy righted material.

They claim 4.5 watts for the low power usage scenario. ARM will be with us for a long time. The ARM folks are climbing the feature/performance curve too. Don't worry about AMD, they are bringing out ARM chips too. Including the ARMv8, aka. ARM64. AMD describes more fruits of ARM embedded partnership

The station wagon can outrun a backhoe.

You need a 3 phase load. That is going to take some careful bolt placement to get the 3 phases matched.

Remind me never to visit your neighborhood.

For the complete simulation, you need to use a generator load tester to burn the 100 or so kilowatts that the machine used.

Microsoft has a habit of padding their sales results. How many of those 100 million licenses are currently in use? Does it include bulk purchases by OEMs? Does a Windows 8 license get subtracted when a user upgrades to Windows 7 or Linux?

Virus 'signatures" are an ideal technology for dealing with common threats from the late 1990s.

The characters built some stuff on the beach, and now they are wandering around trying to figure out how their world works Their world does not work like our world.

The form of story is unusual, in that one must use additional technology to follow it. Which the reading community developed very quickly. I use xkcd.aubronwood.com/.

Stealing power takes a certain level of knowledge and attention to detail. Quite a few power thieves manage to send themselves to the emergency room or morgue each year. This is far more common in regions where the theft rate is so high that the power companies install the brains of the meters on the pole transformers. They just put a remote display on the residence.

There were 70 units available when I read an article about it this morning. 46 left when I started to order my 2. They probably started with more, but still much closer to 10 than 300k.

I ordered two Model A's this morning. (I saw it in the Raspberry Pi news section of Google News.)

I already have a few Model B's. I will develop on a Model B, because the ram makes a performance difference. My projects seem to either need more than 2 USB ports anyway, so the built in 2 port USB hub on the B doesn't help. I usually have an external hub. And most things I do are wireless, so the built in ethernet isn't useful. So why pay the extra 3.5 watts?
