Tiny LIDAR Chip Could Add Cheap 3D Sensing to Cellphones and Tablets 62

There are expensive dedicated devices that do 3D scanning (like the high-end tablet in Google's Project Tango), and versatile but bulky add-ons, like the Sense from 3D Systems, but it's not a capability built into the typical cellphone or tablet. That could change, thanks to a microsensor being prototyped now (at low resolution) at CalTech. From The Verge's coverage: The tiny chip, called a nanophotonic coherent imager, uses a form of LIDAR (Light Detection And Ranging) technology to capture height, width, and depth information from each pixel. LIDAR, which shines a laser on the target and then analyzes the light waves that are reflected back to the sensor, are best known for their use in precision-guided missile systems and self-driving cars.

While LIDAR itself isn't new, [project lead Ali] Hajimiri explains that "by having an array of tiny LIDARs on our coherent imager, we can simultaneously image different parts of an object or a scene without the need for any mechanical movements within the imager." Each "pixel" on the new sensor can individually analyze the phase, frequency, and intensity of the reflected waves, producing a single piece of 3D data. The data from all of the pixels combined can produce a full 3D scan. In addition, the researchers' implementation allows for an incredibly tiny and low-cost scanner, all while maintaining accuracy. According to the researchers, the chip can produce scans that are within microns of the original.

not going to get in anyone's way, etc.

So you can guarantee that for all users and use cases?

Customers like easter eggs.

Which customers are these? Those buying your 99 cent mobile app? Those buying a 50 dollar shrink wrapped or downloaded desktop app? Or those buying multi-thousand dollar enterprise systems?

Assuming the software is generally high quality, they're amusing, minor diversions that add a little fun for the users as well as the programmers.

Again, that depends on who your customer is and what their attitude is to unknown things being discovered in the software that was not documented and was not part of the RFP or compliance documentation.

What you see as a cute dancing frog or "Hello from the developers", some customers see as a sign of shoddy quality control and the possibility of backdoors.

A more intelligent person than the AC who said:

LOL. Which idiot wrote this summary? There were no "graphics on computers" before 1990 then?

There were cars before the Ford Model-T, would you claim that Ford did not user in the era of the horseless carriage?

There were electric cars before the Toyota Prius, but would you claim that Toyota did not user in the era of the electric car?

Ushering in the era doesn't mean you are first, but that you are the most effective/impactful.

By your logic, it should not be said that Apple ushered in the era of the smartphone or tablet, plenty of companies had them before... yet Apple was the first to get it right and establish broad appeal.

Just? Volume enterprise licensing in some form has been around for quite some time, under it you can deploy whatever supported version Windows or Office or other licensed software you like.

Office 365 is the only real new thing as it makes process a little more visible as an individual can sign up for a individual subscription as well.

I want to double down upon what you are saying as you know far better than the parent what is going on.

Just today I had sub-sub contractors from Comcast trying to fix the cable from the box across the street to my home for an issue I first reported the issue in mid-December but after a few months of nonsense things finally got worked out.

After first having a visit from a person who appeared to be a Comcast employee declaring the connection between my home and the distribution box across the street bad (I was seeing .1 mbs upload(should have been closer to 10mbs) yet semi-normal downloads), he wrote it up for replacement... and so began a multi-month process.

A week later received a note from a sub-contractor of Comcast (though with the Comcast letterhead on the door hanger and the sub-contractors name in the fine print) which said my cable needed to be replaced. Over the next couple of months I'd call them to check on the status with the work order # on the tag as things slowly worked their way through the Comcast and local city bureaucracies.

Eventually they told me that the work had been issued to a 'sub-contractor' (really a sub-sub-contractor) who took about a month to get things worked out as well between the city and them (which included two paintings of the paths of various utility lines under and around the street (much to the annoyance of the neighbors who didn't like the paint on their property)).

Finally the day of repair arrived (today) and they did their digging... alas they hit a rock when tunneling under the driveway of the neighbor in front of me (and right next to the distribution box) so they had to fill in most of what they did (amazingly professional in this way) and say that another team from the same company would have to come out in a week with a different boring machine to complete the work.

The pathetic thing about this whole process was that as far as Comcast is concerned, my issue has been resolved months ago by virtue of it being sent to an outside vendor... in the close out email even citing the fact that my signal strength had returned to normal (hint: it hadn't fully).

There is a part of me that is considering dropping Comcast service once this whole repair effort is complete (costing them $5-10k)... however they (unfortunately) provide the fastest internet for the price... when it works.

Not really, you'd still get your name checked off on the voter rolls when you get your ballot and someone latter aggregates the whole thing. Biggest difference is that it would make it slightly less harder to vote for someone else (to prevent their vote) as you might end up being the second person to ask... Vs knowing ahead of time who isn't likely.

Not only did you not read the article I had mentioned previously which pointed to people ending up in jail (even if for brief periods) due to debts, but you didn't even read the one you linked to!

However, there are a few situations when you might face jail time in connection with a debt.

The funny thing is that it even goes on to name some of them! See that first one... about violating a court order? That normally is referred to a contempt, and getting locked up for a day or 90 is one of the possible punishments.

I'm still waiting for someone to cite something which calls what I'm saying bullshit... odd that? Oh right... /.

Getting a contempt order is by no means an automatic thing... you first have to go back to the judge and inform them of the violation, maybe even give a chance to the violator an opportunity to respond... it's then up to the judge if and how they will proceed... in fact this is the same process under which (then) President Bill Clinton was held in contempt. Judicial notices can be fun.

Same goes for a writ of mandamus... once you have a judges order in hand against a civil servant who is refusing to do their job things tend to get moving as a contempt order is always a risk.

Citation?

I love it when I challenge someone for a citation and the first response is someone demanding a citation from me (without any of their own).

You can't be held in contempt for not showing up to a civil hearing, you just lose by default.

While there should have been an or in there... and failure to appear is a valid cause to be arrested in some states... such as Minnesota: http://www.startribune.com/inv...

I've a friend in California whose ex was issued a bench warrant for failing to show up to a child support hearing (there had been a long series of them and he missed two in a row).

And you won't go to jail for not paying a judgement,

You clearly don't know how much power a judge has.

Don't believe me? Try this:

1. You give me your email address
2. I send you an email, in response you send me a signed and notarized document promising to pay me $50,000 within 30 days as a thanks for the email.
3. Fail to pay me within 30 days.
4. After multiple attempts by me to collect on this debt, I go to court and get a judgment against you to pay me the full amount of debt within 30 days (I'll skip the interest in this case).
5. Fail to pay me within the next 30 days.
6. I return to the judge and tell them that you still have not complied with their order.
7. They give you one last chance to comply within the next 7 days.
8. 7 days elapse without payment
9. Judge holds you in contempt.

See how easy that was?

if you fail to repay $1000 the debt collectors come for you, your credit history is wiped and you could even go to jail.

Citation?

The debt collectors actions are civil, not criminal and have no power of their own to have you arrested or jailed.

Now, if the debt collector sues you in court, you fail to appear or fail to pay when the judge has ordered you to repay promptly and do not... then you can get hit with a contempt of court charge which could result in jail time... though this is not unique to debt collections, any engagement with a judge can have the same outcome.

Panda Antivirus Flags Itself As Malware 99

An anonymous reader writes An update to a number of Panda antivirus programs Wednesday mistakenly flagged core files as malware, putting them in quarantine. In doing so, the antivirus system ceased working. Panda's free antivirus, retail 2015 service, and its enterprise cloud-based antimalware service are all affected. The company took to Twitter to warn users: "Please, don't reboot PCs. We'll keep you posted." In an advisory, Panda said the erroneous signature file was "repaired immediately," but warned under certain conditions it is possible for the "incident to persist."
