U.K. Supermarkets Beta Test Full-Body 3D Scanners For Selfie Figurines

Posted by samzenpus in News • View
Lucas123 writes Walmart-owned ASDA supermarkets in the U.K. are beta testing 3D full-body scanning booths that allow patrons to buy 6-in to 9-in high "selfie" figurines. Artec Group, a maker of 3D scanners and software, said its Shapify Booth, which can scan your entire body in 12 seconds and use the resulting file to create a full-color 3D printed model, is making its U.S. debut this week. The 3D Shapify booths are equipped with four wide view, high-resolution scanners, which rotate around the person to scan every angle. Artec claims the high-powered scan and precision printing is able to capture even the smallest details, down to the wrinkles on clothes. The scanning process generates 700 captured surfaces, which are automatically stitched together to produce an electronic file ready for 3D printing. Artec offers to print the figurines for booth operators (retailers) for $50 for a 6-in model, $70 for a 7.5-in model, and $100 for a 9-in figurine.

Anyways, a 10mbit link is fully capable of streaming 1080p video, which is about the most demanding consumer grade application I can think of.

Therefore, I have no idea what possible "divide" the author could be referring to. Furthermore, the author strikes me as being grossly uneducated about the topic because of the blatant misspelling of the acronym DOCSIS.

If he wants to make a better case (which it sounds like he's pushing for some kind of socialist and/or social justice agenda) then he should at the very least give examples of WHAT, EXACTLY these people wouldn't have access to.

He would have a case for a slow upstream (it's common for DSL providers to only provide less than megabit data rates) in health care if, say for example, a medical practitioner needed an HD video feed to evaluate their patient (which doesn't seem to be a likely scenario) but he didn't state that. But, that still doesn't apply to anything else he mentioned.

Third World America

By Required Snark • Score: 3 • Thread
This is another symptom that the US is sliding out of the first world and into the third world. It goes along with our creaky unmaintained road, water and sewage infrastructure, along with our badly out of date airports and crappy passenger rail system.

And then there's our overpriced and underperforming health delivery system. (Note: ACA/Obamacare is a part of the solution, not a part of the problem.) And our failing K-12 education, which is severely underfunded and strangling on bureaucracy.

Along with the steadily declining state level college/university systems. (And before the right wingers start screaming about foreign students, remember that they come from places where it's much harder to get into any school and a lot of the higher educations options are not as good as the US, even with our decline. Both public and private schools love out of country students because they pay full tuition.)

But it's all OK, because the upper 10%, and mostly the upper .01% and above are doing really good. For example six members of the Walton family had the same net worth as either the bottom 28% or 41% of American families combined (depending on how it is counted).

Of course historically low corporate tax levels have nothing to do with this, right?

Although taxes paid by corporations, measured as a share of the economy, rose modestly during the boom years of the 1990s, they remained sharply lower even in the boom years than in previous decades. According to OMB historical data, corporate taxes averaged 2 percent of GDP in the 1990s. That represented only about two-fifths of their share of GDP in the 1950s, half of their share in the 1960s, and three-quarters of their share in the 1970s.

The share that corporate tax revenues comprise of total federal tax revenues also has collapsed, falling from an average of 28 percent of federal revenues in the 1950s and 21 percent in the 1960s to an average of about 10 percent since the 1980s.

The effective corporate tax rate — that is, the percentage of corporate profits that is paid in federal corporate income taxes — has followed a similar pattern. During the 1990s, corporations as a group paid an average of 25.3 percent of their profits in federal corporate income taxes, according to new Congressional Research Service estimates. By contrast, they paid more than 49 percent in the 1950s, 38 percent in the 1960s, and 33 percent in the 1970s.

So it it any wonder that the US is at best standing still, and more likely moving backwards when it comes to national infrastructure spending? And guess where the money goes?

Huh?

DOCSIS 3.0 does not have a maximum limit on the number of channels that can be bonded.
The initial hardware would only bond up to 8 channels (~304 Mbit/s), but 16 channel (608 Mbit/s) hardware is already being rolled out by Comcast in the form of rebadged Cisco DPC3939 Gateways.

2015/2016 we might see 24 channel (912 Mbit/s) and 32 channel (1.2 Gbit/s) hardware.
2016/2017 is most likely, in the form of DOCSIS 3.1 modems, which use completely different modulation, but will have 24/32 channel DOCSIS 3.0 baked into them so that the ISPs can seamlessly upgrade from DOCSIS 3.0 to 3.1.

Cable's game plan is to use DOCSIS 3.1 to put off pulling fiber to the home, which keeps their costs low and will allow them to offer (multi)gigabit speeds using a hybrid fiber/co-ax infrastructure.

Oldest Human Genome Reveals When Our Ancestors Mixed With Neanderthals

Posted by samzenpus in Science • View
sciencehabit writes DNA recovered from a femur bone in Siberia belongs to a man who lived 45,000 years ago, according to a new study. His DNA was so well preserved that scientists were able to sequence his entire genome, making his the oldest complete modern human genome on record. Like present-day Europeans and Asians, the man has about 2% Neanderthal DNA. But his Neanderthal genes are clumped together in long strings, as opposed to chopped up into fragments, indicating that he lived not long after the two groups swapped genetic material. The man likely lived 7000 to 13,000 years after modern humans and Neanderthals mated, dating the mixing to 52,000 to 58,000 years ago, the researchers conclude. That's a much smaller window than the previous best estimate of 37,000 to 86,000 years ago.

Re:Question for sequencing expert.

By kinko • Score: 4, Informative • Thread

I don't know if ancient samples are processed differently, but for 'fresh' samples, the DNA gets broken up into small fragments (200-1000 base-pairs long), and then these fragments get sequenced. All bits of the genome have roughly even chance of getting sequenced, and with thousands or millions of copies of each fragment, you normally get reasonably even coverage over the whole genome.

The problem is when you map your sequences back onto a reference genome (ie the currently known chr1, chr2, chrX, etc). The aligning software will have trouble deciding where to place a fragment that is part of a highly repetitive sequence (like centromeres or telomeres) , or is duplicated several/many times (eg large gene families that have large sections of the genes in common, or pseudogenes that look like copies of other genes). In addition, we don't even know the exact sequence for some of these regions, so our reference human genome is contantly being updated (currently up to version 38).

For bioinformatics analysis, sometimes it is easier to sweep some of this under the rug. For example, some people use a reference genome that masks out the centromeres and telomeres (ie our reference sequence just has NNNNNNNNNNNN bases here, instead of As,Cs,Gs and Ts). Otherwise there are databases that list the regions containing repeated sequences or duplicated segments, so you can check any of your findings to make sure they aren't in a suspicious region.

Mod parent up. The article as written is dumbed down and misleading in many ways. Against my usual temperament I'm going to make a sociological/anthropological argument that someone reading the article will draw very wrong conclusions about the nature of prehistoric Neanderthal-modern human interaction. Genetic inheritance or progeny happens to be the only evidence we have right now about early Neanderthal-modern human interaction. But it does not say anything useful about when we "first had sex with" them as the article claims. Consider the following: Archaeological evidence suggests that large scale violence we would consider warfare was a part of human life as far as 7,500 or possibly 14,000 years ago. Does that mean ancient society was all about peace and love before that time? No. There is too little information to make such sweeping conclusions. To return to the subject at hand, not all sexual encounters with Neanderthals are going to leave evidence for us to conveniently find. What we *DO* know at this point is that at least one such encounter resulted in a pregnancy that was carried to term and the resulting offspring lived long enough to have children of his/her own who continued to survive. That's ALL we know. Put another way, imagine the young men and women of ancient communities playing a game of "fuck, marry, or kill" that included their funny looking neighbors. The visual may not be pleasant, but any earlier incidents of war-rape and deliberate infanticide due to parental rejection will leave little to no evidence behind for us. And barring extreme luck, there is almost NO WAY we can know if/when such incidents occurred. Who really knows when Neanderthals and us *FIRST* had sex?

Re: Exinction

By jc42 • Score: 4, Insightful • Thread

My guess is that the fact that no organisms exist with a Neanderthal genome defines them as extinct. Where one draws the line is more art than science I guess ... I know that there are some genetics in us (like the HMG group of proteins) that are ancient, but work so well that we still retain them. That doesn't mean the first species to have evolved them isn't extinct, it just means we evolved from them.

Well, I don't think that quite matches the scientific concept of "species". By your definition, almost all species who were alive 50,000 years ago would be considered extinct, but hardly any biologists would agree with that. It's true that no humans alive today have 100% Neanderthal genes, but it's also nearly certain that there are no living humans with 100% Cro-Magnon genes, either. What happened would be considered a mixing of several human sub-species after migrations of one or more African groups into Eurasia. The Cro-Magnon sub-species disappeared, too, and modern human Caucasian and Asian sub-species are the results of that mixing. This sort of thing happens in species all the time, when conditions allow such genetic mixing, and the result is rarely considered a new species.

The fact is that modern humans are all one species. We can and do interbreed when groups mingle, and there are no groups of modern humans that are genetically incompatible. If sub-species "disappear" by genetic mixing, that is usually not called an extinction event. It's just the routine and normal mingling of subspecies.

An interesting contrast is that most North American duck species are known to hybridize occasionally, and the offspring are usually fertile. Does this mean they're really all one species? No, because they all mingle a lot, but interbreeding is rare. They have "behavioral" species-separation features, mostly based on female mate choice. The females are mostly all mottled brown (protective coloring), and the males often approach females of other species (because they can't tell them apart either ;-). But the females usually only accept males that have the "right" color markings; the others are ugly to them. This suffices to keep the species separate, though there is probably a very low level of genetic interchange between many of the species.

But humans aren't like this. Even if we do generally prefer mates in our own subspecies, most of us do find many members of other subspecies physically attractive, and we'll mate with them given the opportunity. This means that we really are all the same species. We now have good evidence that the Neandertals were merely another subspecies, because when they had the opportunity, they did interbreed with those slender, dark-skinned folks who migrated into their territory. They did so often enough to produce a new subspecies that's physically distinct from either of the earlier two (or three or more).

The way Cisco is calculating the mb/s seems to be via some sliding window, which allows a quick spike of a burst to happen in the first 1/4 of a second, but then clamps down. Because my network latency is so low, the TCP stream can ramp up really fast. Once the Cisco router clamps down on the connection, I'm already uploading nearly 100mb/s and TCP can't back off in time before loss happens.

The reason loss occurs after the clamping is because my ISP uses small buffers. They don't like buffer bloat. My max latency to my ISP before loss starts to occur is about 10ms. Since the connection is dedicated, and their trunk is sized about 3x more than peak bandwidth, it's normally not an issue.

This wouldn't be an issue if DropBox transferred the data as a single stream, but instead does a very jarring start/stop cycle, which causes my bandwidth to get very spiky. I'm thinking of enabling traffic shaping on my PFSense box, but I really don't feel like messing with it quite yet.

I guess the actual problem really is the Cisco router, but DropBox is still incredibly slow.

It's not that difficult. But after setting it up for a group of people and then setting up seafile, I prefer seafile. If you aren't an admin user in owncloud, things are pretty tough when it comes to knowing what groups you are in and what groups can be shared with and such. seafile does a much better job on that front.

Plus the owncloud sync client doesn't seem very good. And the mobile platform clients cost money where seafile is free.

ownCloud might have gotten the 'good name', but they don't have the best implementation sadly.

Deutsche Telecom Upgrades T-Mobile 2G Encryption In US

Posted by timothy in Management • View
An anonymous reader writes T-Mobile, a major wireless carrier in the U.S. and subsidiary of German Deutsche Telecom, is hardening the encryption on its 2G cellular network in the U.S., reports the Washington Post. According to Cisco, 2G cellular calls still account for 13% of calls in the US and 68% of wireless calls worldwide. T-Mobile's upgrades will bring the encryption of older and inexpensive 2G GSM phone signals in the US up to par with that of more expensive 3G and 4G handsets. Parent company Deutsche Telecom had announced a similar upgrade of its German 2G network after last year's revelations of NSA surveillance. 2G is still important not only for that 13 percent of calls, but because lots of connected devices rely on it, or will, even while the 2G clock is ticking. The "internet of things" focuses on cheap and ubiquitous, and in the U.S. that still means 2G, but lots of things that might be connected that way are ones you'd like to be encrypted.

The Classic Control Panel In Windows May Be Gone

Posted by timothy in Technology • View
jones_supa writes In Windows 8, there was an arrangement of two settings applications: the Control Panel for the desktop and the PC Settings app in the Modern UI side. With Windows 10, having the two different applications has started to look even more awkward, which has been voiced loud and clear in the feedback too. Thus, the work at Microsoft to unify the settings programs has begun. The traditional Control Panel is being transformed to something temporarily called "zPC Settings" (sic), which is a Modern UI app that melts together the current two settings applications.

Maybe I am wrong, but over the years I have noted an increasing condescendension of IT people over "mere users". I wonder why that is. Bear in mind that IT typically isn't the company's cash cow, but "overhead", making this condescension rather inappropriate imho. Even on /. there are many "users" that are no IT people: designers, programmers, etc. I wonder why the interface they are using is apparently less important than computer maintenance software, or any other user experience, for that matter.

The "overhead" designation is precisely the reason IT people tend to hate users (at least in my experience). The end-user sees the IT person as nothing more than an electronic janitor who's sole purpose is to clean up the messes that they, the user, were too careless or too inept to prevent from happening in the first place. Thus, they don't bother to learn how to do things properly, they don't learn how to keep from getting a virus, they don't learn how to do even the simplest of things because "That's IT's job. I shouldn't have to know computers!" No, they don't have to know the ins and outs of every modern OS, but they should know how to at least keep it from obliterating everything they're working on (meaning stop clicking "OK" on every damn thing that pops up!). Then to top it all off, they behave as if security policies, best practices, etc. don't apply to them, even though management approved them as being a site-wide mandate...

So in short, users see IT as "the help" and treat them as such. And much like a janitor who is constantly cleaning up after idiots who have no concern for anyone other than themselves, the IT worker learns to hate certain users because they seem to have a mission in life to make IT's job as miserable as possible.

Why a GUI? Well, back in the day....

That's one thing I never understood, why Microsoft went GUI with the servers like they did, other than to know that they sold a lot of server OSes to people that had no business running servers in the first place...

Simple. Most business people had been exposed to DOS, then moved to Windows and found it much easier to use and understand. The Novell guy comes in and tries to sell a Netware server. Yep - looks like DOS. I came in with a Windows server. Looks just like his PC. He sees File Manager, drive letters, Notepad, Paint, and suddenly he feels like this is the more advanced system, and he is far more comfortable with it.

A lot of the Netware guys around my area were extremely arrogant, and treated their customers like crap. Once they got a server installed, the customer was clueless and the vendor would abuse that. Our business model was to be open with the system and point out that we can easily be replaced, keeping us focused on their satisfaction. With NT Advanced Server (the correct name), the business owner could actually watch us and understand what we were doing with his system. We replaced a fair amount of Netware servers in those days. And you can see who won.

So that multiple programs can share the same settings system-wide. The worst thing about Linux is that every program works in a different non-standard way.

Like putting system config in /etc and user config in $HOME, you mean?

Like putting system config in HKEY_LOCAL_MACHINE and user config in HKEY_USERS, you mean?
The registry is trash, but so is a mish-mash of non-standard textfiles strewn about.

The problem that's specific to Windows is that programs can decide to use the registry, text files, or both, and when they use text files they can be in my documents, (which is now a library with no fixed location), the program's installation folder, the system-wide application data folder, or a user-specific application data folder. When using an application data folder, you have the choice of using Local, LocalLow, or Roaming. No one in the world understands the difference between these folders or why some programs use one over another (or use multiple!).

It wouldn't be a problem if everything was relegated to living in one of:
A: The application's install directory
B: A single directory (one per application) in a specific user/system directory (or both)
C: Living in the registry (again, user/system/both as appropriate)

But when applications can choose A, B, C, A & B, A & C, B & C, or A, B & C it's a fucking nightmare.

Judge Says EA Battlefield 4 Execs Engaged In "Puffery," Not Fraud

The suit claimed executives were painting too rosy of a picture surrounding what ultimately would be Battlefield 4's disastrous debut on various gaming consoles beginning last October, including the next-generation Xbox One. But US District Judge Susan Illston of San Francisco said their comments about EA and the first-person shooter game were essentially protected corporate speak. "The Court agrees with defendants that all of the purported misstatements are inactionable statements of opinion, corporate optimism, or puffery," Illston ruled Monday.

The former employees filing lawsuits against Microsoft, Ask.com and Oracle have asked that the cases be assigned to Judge Koh as there were similarities with the case against Google, Apple and others — and it maybe doesn't hurt that Judge Koh thought the $324.5 million settlement in that case was too low.

FTDI Reportedly Bricking Devices Using Competitors' Chips.

Posted by Soulskill in Hardware • View
janoc writes It seems that chipmaker FTDI has started an outright war on cloners of their popular USB bridge chips. At first the clones stopped working with the official drivers, and now they are being intentionally bricked, rendering the device useless. The problem? These chips are incredibly popular and used in many consumer products. Are you sure yours doesn't contain a counterfeit one before you plug it in? Hackaday says, "It’s very hard to tell the difference between the real and fake versions by looking at the package, but a look at the silicon reveals vast differences. The new driver for the FT232 exploits these differences, reprogramming it so it won’t work with existing drivers. It’s a bold strategy to cut down on silicon counterfeiters on the part of FTDI. A reasonable company would go after the manufacturers of fake chips, not the consumers who are most likely unaware they have a fake chip."

Except the chip wasn't, as you put it, "killed." The chip is still fully functional with a driver that will support it.

The chip was pretty killed. With a PID of 0, Windows, Mac OS, and Linux wouldn't recognize it. It's theoretically possible to fix the PID, but most end users wouldn't really know how to do that.

Why should FTDI support chips it didn't make?

They shouldn't have to support chips that they didn't make, but at the same time, they shouldn't brick* chips that they didn't manufacture.

What FTDI really should have done is to set a generic PID for the chip type. That way, the chip would no longer use the FTDI driver, and they wouldn't have to support it.

*I use "brick" in the sense that using their Windows driver to set the PID to 0 makes the chip no longer function in other OSs, either. I am aware that an unbricking procedure is available.

Yes. A company called Supereal is selling enormous volumes of "FTDI" chips into the Chinese market. The chips are labelled with the FTDI name and logo and during the USB negotiation, they announce themselves using the FTDI vendor unique ID, in order to use the ubiquitous and flexible FTDI driver (rather than require any development work for their own driver).

See http://zeptobars.ru/en/read/FT... for an example of a fake chip - labelled FTDI on the outside, but supereal on the silicon.

The problem is that the fake chips are buggy and slow compared to the genuine article, causing headaches for USB peripheral designers and support and reputation headaches for FTDI. There is a huge market for USB UART chips, and it is quite competitive, but few of the products on the market are actually as reliable, fast and robust as you would expect them to be. The FTDI FT232RL is one of the best in terms of reliability and has the best drivers, while also providing some handy bonus functionality.

It appears that FTDI have reverse engineered the fake chips and found that they can be reprogrammed. When their driver detects a fake chip, it uses the internal configuration commands to erase the EEPROM memory containing the Vendor Unique ID. With this EEPROM blanked, the chip is unable to complete the device detection process in the OS's USB stack.
