Also from TFA, they have made 10,000 samples on their production line. They are initially aiming at the power company market, thus huge batteries with huge price tags. They are targeting $100 per kilowatt hour by 2020. One of the co-founders also co-founded A123. So there is some experience at bringing batteries to market.
Lots of companies fail for reasons besides their technology. I won't be surprised if this one fails too. On the other hand, it is more real than most such slashdot stories.
They are not orthogonal. This should have been titled "if you are going to use Kali Linux on a Raspberry Pi, here is how to encrypt it".
Kali Linux is designed for penetration testing, among other things. The logs from a penetration test are valuable to dark hats. The advantage of doing this from a Raspberry Pi, is that they are cheap enough to send to each branch of a company, so each network can be individually tested. Sometimes this means that physical security is difficult to ensure. It would be very embarrassing to lose a system during an internal audit. It could quite easily turn into a career ending event, if that led to a security breach.
Disclaimer: I've never used Kali Linux, nor did I look closely at this technique to see if there is something stupid in the instructions.
I want clean clothes, I don't need something to clean them the way I would clean them. I am willing to buy clothes that are robot cleaning compatible.
I like machine assisted dish cleaning so much, all of the dishes we own are "dishwasher safe" except for a couple wine glasses. They aren't all labeled dishwasher safe, but in those rare cases when the dishwasher destroyed something, I made sure not to buy another dish with that weakness.
Likewise, all of the clothing I use on a regular basis have survived trips through the washer and dryer.
For me, a complete laundry system would take the clothes out of the hamper, wash and dry them, and put them away. In order to put the clothes away, the robot would need to know where they are supposed to go and how to prepare them for storage. I am not afraid of RFID tags, but if I were, there are many other options for creating labels a robot can read.
Folding clothes isn't hard once the clothing is identified, flattened and positioned. The robot readable labels take care of the identification. In exchange for something else doing the work, I am not adverse to having ferrous rings sown into key points, so the system can magnetically grab those points to spread out and align the garment in the folding station. I am not adverse to having clothes rolled up, if that turns out to be easier.
I don't require that a robot adapt to my garage sale dressers. I just need the right clothes in the morning. There are many pick and place technologies. If for some reason it is easier for the cleaning system to deal with cartridges, I can live with that. The cleaning system can load an underwear cartridge. The transport system can load the cartridge into my dresser replacement. Then the dresser replacement can dispense underwear as needed.
Anthem is traded on the NYSE under the symbol WLP.
They should be required to file an 8K form to legally inform all of their stock holders that they have material news that may adversely affect their future stock price, or even company viability.
After having been informed of extreme security issues on our network, Anthem Inc has elected to ignore the situation.
Furthermore, Anthem Inc's network is so embarrassing, that Anthem Inc has decided to risk significant fines and legal
expenses, rather than allow adults to see just how bad it is.

This is more than just a selfie, the shadow cast by a known object adds depth, scale, and many other scientifically interesting details about the comet, and about the space craft itself.
And for those who like science fiction... If any aliens are riding the Rosetta probe, they will have to duck while the picture is being taken.
In the days of brick and mortar spying, the people being spied on would send messages that included false meeting times and locations. For example, in a town with underground utilities, announce a meeting to take place in a rarely used manhole. If the manhole cover is disturbed, then you know that the communication channel has been compromised. No math is required.
The high tech equivalent would be to mention a network resource where access can be monitored. When the network resource is accessed, you know there is a problem.
An earthquake might move the ground north of a fault to the west, and the ground south of the fault to the east. The tube has to stay straight enough that the train can come to a complete stop safely. This means a whole bunch of columns will have to bend.
If your data is valuable, you will need to mirror the drives or use RAID. So one limitation is how quickly you can add a drive to your mirror system.
It would take 11 hours to fully mirror from one 6 TByte WD drive to another, if your system can actually manage to sustain 138Mbytes per second as shown on page 5 of the article. Obviously, the transfer will be slower, if the data is actually used for something.
If a disk dies, at best you are looking at half a day before the system is fully redundant again. Probably multiple days in the real world.
They are working with 6 mm samples. They need to improve that by a factor of 5. Only a small percentage of women at risk for breast cancer can tolerate having their breasts compressed to 30 mm for imaging, but it is a large enough percentage to start doing human test trials. Assuming the image quality is high enough.
With existing xray based mammogram machines the more the breast is compressed, the better the image. There is abundant research on breast compression for imaging, just a google away.
Perhaps in a few years, this technique will be refined to the point where it can image through 3 cm of tissue in a reasonable amount of time, and produce a clinically useful image. Then we will hear about this technique again. Hopefully, it will be improved to the point where it is suitable for use on the entire population.
It's like there is this long, infinite road and along this road are mile markers and every so often one of these mile markers has a rest stop at it. Mile marker 3, 5, 9, and so on. The farther your drive however the more you notice how spread out these rest stops are, eventually having thousands upon thousands of miles between them. Then, as in this article, you discover a pack of six rest stops very close to each other when all the other ones were thousands of mile markers apart. Thats probably the closest I can get this to a car analogy.
There are rest stops at 2, 3, 5, 7, 11, 13, and so on, but 9 is not a rest stop. The first two overlapping sets of six rest stops aren't spaced the same as the rest, and thus don't have the same mathematical properties. The Riecoin compliant prime sextuplets, err, I mean rest stops on the infinite highway are {7, 11, 13, 17, 19, 23} and {97, 101, 103, 107, 109, 113}, except they are too small for cryptography.
TFA says that Home Depot expects to pay "$62 million this year to recover from the incident", referring to exposing the details on 56 million credit cards. That's only $1.11 per exposed card. I used a credit card there during the period, so my Credit Union sent me a new card, plus two other physical letters about the incident. That had to cost them more than $1.11 per affected customer.
The fake chips that have FTDI stamped on the outside of the package are clearly misusing the FTDI trademark. On the other hand, those that don't cheat with the labels, and only use the string "FTDI" so they will inter-operate with existing software should be legal.
I am not a lawyer. My opinion of what should be legal may not match what the courts rule as legal.
Sometimes the variations in reviews is due to variations in the product. Many years ago I worked in a brick and mortar store and resold electronics. I'd buy a small number of units from a supplier and test them. If they were good, I'd buy a bunch for resale. Assuming the customers didn't bring them back, I would buy more of the same, from the same vendor. Customers who were happy with units from the first few batches, were not at all happy with units from later batches.
I dissected customer returns. Again and again, the products in later shipments looked identical on the outside, but were "cost reduced" on the inside. For example, I would see empty places on the circuit boards where the filter capacitors were supposed to go. In one batch of one product, many of the units were dead on arrival, on the ones that worked when I unpacked them, the solder joints only lasted a few weeks. Once opened, I could see that the boards were either soldered at the wrong temperature, it was the wrong type of solder, or badly made solder. Every connection was visibly a cold solder joint. Either the factory had no quality control, or they ignored the quality control.
Other products looked identical inside and out, but based on the failure rate, the factory must have gotten a bad batch of one the components.
Even longer ago, I worked on a product that logged data to a Compact Flash memory card. It was an embedded product that needed to work across a wide temperature range, including in the winter in Minnesota. The big names like SanDisk would randomly swap component suppliers. Our largest customer saw less than a 2% failure rate, but that was way too much. We found a specialty supplier that charged 5 times as much, but they had a rigorous quality control process. They paid attention to the specifications. They tracked where parts came from, and promised that we would be able to test sample units if they needed to switch suppliers. Alas, the 2% failure rate from the earlier parts had already doomed that product line.
The Fine article compares this type of lattice structure to the structure of the Eiffel Tower. They didn't claim anything more than being able to do it at a very fine scale, and to do it sufficiently precisely to get something that can support 160,000 times its one weight. They are just claiming refinements on centuries of engineering advances.
The strength of well engineered 3D printed structures is still impressive. Even some printers that hobbyists can afford can beat out solid materials. It's only getting better.
These will be used in data centers where it is common to have redundant systems connected with redundant cables, in order to maintain really high uptimes. Say a hypothetical system has a cluster which consists of 16 compute nodes and 2 storage nodes, Each of CPUserver01 through CPUserver16 will have two of these cables going to storageServerA, and two going to StorageServerB. For a total of 64 of these cables, for that one little compute cluster. Which would leave it an island, so of course there will be more network interfaces.
For this technology to get any market penetration, it will need to be cost effective at these bandwidths, and fit in the racks. Historically, Dense Wavelength Division Multiplexing, DWDM has been great at getting a lot of bandwidth on to a very long single strand (comparatively) inexpensive fiber, which allows in fiber signal amplification, and is the winner at going the distance, but not so good at being cost effective, or space efficient. These things, with the associated drivers should take up far less space inside the servers, and cost less, but they only will get 800Gbits in each direction, only go 300 meters, and use much more expensive (per kilometer of cable) 64 strand fiber.
Rigid silicon requires rigid interconnects. Flexible ICs allow flexible packaging, or different packaging. Instead of building from the printed circuit board up, build from the heatsink up. Use a precision pick and place system to glue the thin, wimpy, inexpensive silicon to the strong massive heatsink. Then mask on the solder balls. Then apply a thin, wimpy, inexpensive circuit "board". Attach all the old style surface mount components to the other side of the circuit "board". "Board" is in quotes because it would get all of its mechanical strength from heatsink. It might be so thin, it is no longer board like.
The big win here, is that one wafer is good for at least 5 sets of circuits. The lose is the grid of holes etched through the silicon as part of the pealing process. Assuming the grid of holes doesn't use up a significant portion of the surface area, the factory is getting close to 5 times as many devices out of each ingot of silicon.
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
no connector to wear out,
alignment is simple.
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.
