I read an article recently on exactly that topic, which is probably worth quoting:

The market is fully capable of pricing the fact that Alibaba stockholders don't actually own a direct claim on Alibaba's Chinese assets and can't elect its board. Truth be told, shareholders don't "own" any company; they own whatever rights are specified in the share agreement........

True comfort for shareholders comes not from legal boilerplate, but from incentives. Alibaba founder Jack Ma could take the $22 billion raised Friday and stiff his foreign partners. That's a risk. But his self-interest is otherwise. He wants a strong stock as a currency for acquisitions. He wants stock options to motivate his increasingly global management team. He wants easy liquidity for himself and other insiders. .....

when investors begin to worry about the actual rights specified in a share agreement, it usually means something has already gone seriously wrong.

Alibaba is probably as good as any stock. If things go wrong, things go wrong.

Don't worry. This technology seems really great for entertainment, but I fail to see a real use for it in most workplaces. How exactly is typing a letter or filling in data in a spreadsheet enhanced by VR? If anything, augmented reality would be more helpful, allowing contextual data to be displayed on-demand.

Besides which... hell, Windows 8 was too radical for the corporate world. And remember the furor over MS changing the Office interface? You really think they're going to start strapping VR headsets on people anytime in the near future?

It is AMD fanboy sour grapes. For some reason some people get really personally invested in their choice of graphics card. So when the other company comes out with a card that is substantially better than what their company has, they get all ass hurt and start trying to make excuses as to what it is bad. The nVidia fans did that back when the AMD 5870 came out and nVidia had no response. Same deal here. The GeForce 900 series are a reasonable bit faster than the AMD 200 series, and way more power efficient. At this time, AMD doesn't have a response, so the AMD fanboys are going on the defensive.

The real answer is, of course, buy the card that works best for your usage, which will vary person to person.

Imagine if a state like Mississippi or Oklahoma had to get a system made? They'd hire a guy named Jom Bob from church to do it. They'd piss away the entire budget before they even found Jim Bob. They'd run it on index cards and toilet paper in type writers with no correction ink.

Well to be fair the deep-red state Kentucky had a very successful rollout of Obamacare (rebranded as "Kynect"), including it's own health insurance exchange AND medicaid expansion -- the whole Obamacare enchilada.

Under Obamacare, the federal insurance exchange was never intended to serve the entire country. In fact ideally nobody would have to use it, because states were supposed to set up their own exchanges that would better reflect the needs of their citizens than a federal one would. If you are forced to use the federal exhange, it's because politicians who run your state made that choice for you.

Of course some states have had their own exchange rollout disasters -- including blue states like Maryland and Oregon. If you're experienced with this kind of project you'd expect that. But others have had very successful rollouts, including a handful of red states like Kentucky.

Encryption is only enabled during transmission, but not at rest. The default backup program doesn't currently support the S3 server-side or client-side encryption protocols. If you really need to secure your data and can't trust S3's basic security, then this solution may not work for you.

There are 3rd party backup apps that do client-side encryption, but they use their own cloud services, not S3, so you'll probably pay a bit more for it. You may be able to use a standard Linux backup application, but there are no guarantees there, and you'd have to be comfortable enough to do a bit of tinkering under the hood to set it up manually.

It's cute to see how much money they blow on their designs, but really, is this news, or stuff that matters?

You would be amazed how unselfaware many startups are. In the late 90's, early 2000's time period I frequently had to remind people in companies with 2 - 200 employees selling niche products that "But Microsoft does it that way!" was an argument against doing it that way for us, because we were anything like Microsoft in terms of resources, product or market.

You'd think that no one would ever have to be told that, but the reality is that most people look at something as incredibly difficult to build as Windows (in software) or an iPhone (in hardware) and think, "Yeah, I could knock that out over a weekend and ship a few million units a year, no problem!"

Yep, I saw that and considered switching, but at the moment, there are a lot of handy S3 browsing and transfer tools, and not so much for Glacier (at least when I last looked - maybe that's changed). If I needed to, I wanted to be able to view or even retrieve my data with a simple Firefox plugin. Also, of course, there's almost zero financial incentive for me since I'm transferring such small amounts. Since I currently have a relatively slow DSL connection, backing up large amounts of data isn't all that practical anyhow.

For those with a lot of data to push up (photos, videos, etc), I absolutely agree. A weekly backup to Glacier makes a ton of sense, as it's designed specifically for backup scenarios.

... Before that it can't, because Ta^4 - Tb^4 is a positive number so no net radiant energy is absorbed by (a) from (b). That means all the way up to the exact point thermal equilibrium is achieved, all radiant power is a result of electrical power, therefore the power input and power output are constant. It is not a "gradual" process. ... [Jane Q. Public, 2014-09-20]

So Jane claims:

electrical power per square meter = (s)*(e)*Ta^4

The actual answer is:

electrical power per square meter = (s)*(e)*(Ta^4 - Tb^4)

Since Jane refuses to include a term accounting for radiation from the chamber walls, Jane's equation is saying that no radiation at all is absorbed by the warmer source. Why?

... Since the chamber walls are COOLER than the heat source, radiative power from the chamber walls is not absorbed by the heat source. ... [Jane Q. Public, 2014-09-15]

Of course it is! Again, this is just Sky Dragon Slayer nonsense. Absorption doesn't work like Slayers imagine. It's controlled by the surface's absorptivity, which doesn't change if the source is slightly warmer or cooler than its surroundings. All that's required for the source to absorb radiation (from warmer or colder objects) is having absorptivity > 0. Since the source has absorptivity = 0.11, some radiative power from the chamber walls is absorbed by the heat source.

Jane's been regurgitating Slayer nonsense for years:

... Warmer objects cannot, and do not absorb lower-energy radiation from cooler objects. ... [Jane Q. Public, 2012-11-20]

Then how do uncooled IR detectors see cooler objects? How did we detect the 2.7K cosmic microwave background radiation with warmer detectors?

... explain how radiation that is of a LOWER "black-body temperature" will be absorbed by a body of a HIGHER black-body temperature. ... [Jane Q. Public, 2013-05-30]

... An object that is radiating at a certain black-body temperature WILL NOT absorb a less-energetic photon from an outside source. This is am extremely well-known corollary of the Second Law. ... [Jane Q. Public, 2013-05-30]

No, that's a Slayer fantasy. On the atomic scale, absorption of radiation doesn't depend on temperature because individual atoms don't have temperatures. Only very large groups of atoms have temperatures. Individual photons also don't have temperatures. Very large groups of photons from a 10C warm object have slightly different average wavelength curves than a -10C cold object, but they're very similar. This means that even if temperature somehow applied at the atomic scale of absorbing individual photons, an atom couldn't tell if a photon came from the 10C warm object or the -10C cold object.

... You took a badly-worded sentence or two and jumped on them as though Latour made a mistake. But his only mistake was wording a couple of sentences badly. He does in fact NOT suggest that warmer objects absorb no radiation, and he has written as much many times. ... You have refuted NOTHING but a couple of unfortunately-worded sentences, which Latour himself publicly corrected shortly after that post appeared. ... [Jane Q. Public, 2014-07-27]

Ironically, Jane's still insisting that warmer objects absorb no radiation from colder objects. Otherwise Jane wouldn't repeatedly object to including a term for radiation from the chamber walls in his calculation of required electrical power. Since Jane doesn't even include that term, Jane's assuming that warmer objects absorb no radiation from colder objects.

... shortly after Latour published that blog post, it became clear that the language he used implied that no radiation at all was absorbed by the warmer body. So a reader could not reasonably be blamed for inferring that. But Latour quickly apologized for the unfortunate wording and corrected himself to make it very clear he was referring to net, not absolute, heat transfer. ... [Jane Q. Public, 2014-07-27]

Ironically, Jane's still insisting that no radiation at all is absorbed by the warmer body. Otherwise Jane's calculation of the required electrical power would include a term for radiation from the chamber walls. Since Jane adamantly insists that this term can't be included, Jane's calculation assumes that no radiation at all is absorbed by the source. None. Zero.

It's truly surreal to watch Jane repeatedly double-down on nonsense which Jane claims is too ridiculous even for Sky Dragon Slayers (as if that were possible!).

2- Safety concerns: with baby and/or young children I felt I would rather not add RF generator inside my home. I know we are immersed in RF from everywhere, making some a few meters away is another level. I didn't want to add that. Just in case.

Ham radio operators -- of which I am one -- spend their lives immersed in more RF at various frequencies from kHz to GHz than you can possibly compare to unless you work at a broadcast radio or television station. And hams are one of the oldest demographics in the USA. So many 80 and 90 year olds, it's really kind of amusing. RF is not your enemy at wifi router and cellphone levels. Not even close.

I've been pretty much bathed in RF for the last forty years. I'm very healthy other than a few allergies I've had since I was a kid. Of course, I'm active, too -- but if RF at these levels was a problem, I'd *have* a problem by now.

How many QA engineers does it take to screw in a lightbulb? 3: 1 to screw it in and 2 to say "I told you so" when it doesn't work.
