Be careful about cherry picking your science, or letting others do so for you.
Dr Lindzen's claims about climate change have so far failed to convince most of his colleagues. While I sincerely hope he turns out to be correct, most climate scientists disagree with him - and the conclusions of AR5's broad review of recent science papers reflect that (as do numerous other surveys and studies). A summary of the results of thousands of peer-reviewed studies carries considerably more scientific weight than a lone dissenting voice with unconvincing evidence. Further, choosing to believe a single scientist's opinion while dismissing nearly all other climate scientists' opinions is a prime example of selection bias.
Your comment is really just more evidence of what I was saying.
Let's stick to the science, whether it supports AGW or not (at the moment the probability of AGW being the most significant factor in our climate is decreasing - as far as I can tell).
Then maybe you should be looking more closely at the actual science, as the IPCC AR5 review upgraded their assessment of the majority of climate change being human-caused to "extremely likely" (95%+ probability). And while a few specific effects of climate change are now considered less likely, others such as polar ice melt have been outstripping projections.
Be careful about cherry picking your science, or letting others do so for you. Read the AR5 executive summary for yourself; it's by far the most comprehensive review of the actual science. And its conclusions are not that everything's fine - quite the opposite.
Ah yes, detailed, studies conclude that mitigating climate change will save us trillions by 2100, but you prefer to believe some guy on YouTube who naïvely extrapolates a number he pulled out of thin air (exactly where did he get that ridiculous starting figure from anyway?). You're right about the "simple" part.
Nope, and it won't until more devices have solid video encoding support. The Android MediaRecorder is still limited to encoding from the camera only, and I'm not sure if any MediaCodecs can be made to encode from an OpenGL buffer.
You'll have to stick to DLNA (wouldn't it be nice if Chromecast supported that), or hope that Koush et al persist in their efforts. Or just pay $40 for a generic Android stick and run a DLNA server on that.
Agree completely. Personally I was really hoping for the Chromecast stick to support DLNA rendering robustly (and maybe it will yet be hacked to do so).
In the meantime, while I sincerely hope Koush continues his efforts, it's no surprise that his little workaround got broken. Might even be deliberate like he claims, but the API warning is right there in black & red.
Let's see what's possible after the API is finalised; Google may not be willing to throw the content gates too widely open, but they've always been hacker-friendly for the two-brain-cell market.
If you read the original post, it only breaks Koush's Cast app for Android, which worked around the whitelisting restrictions to cast content directly.
Read Koush's actual post - the update breaks his Cast app for Android, which works around the app whitelisting to stream directly. Nothing says anywhere that casting arbitrary content from Chrome tabs is broken.
For a target BER [bit error rate] of 10^-2, the receiver can receive at a rate of 1 kbps at distances up to 2.5 feet in outdoor locations and up to 1.5 feet in indoor locations.
Range is improved a little with slower bit-rates, or in the presence of stronger ambient RF.
I have a similar NFC tag in my car. And yeah, I could get Tasker to use non-data charging as a trigger instead, but I also do non-data charging by my bedside. And since I have a different bluetooth radio there and don't want GPS or max brightness, I use a second NFC tag for that with silent profile, no notification lights and screen dimming instead.
NFC isn't the answer to everything, but it's occasionally quite handy, such as sharing youtube or map links with a quick tap, no app required.
Actually, there is a possible hardware fix. Palmer Luckey has been looking into it for some time. But it's something that has to be treated with caution, for fairly obvious reasons.
Some people may take longer, two or three weeks or whatever - but if you're feeling more than just a touch of queasiness, you're overdoing it. It should be fun, not a burden. If you push yourself too hard and feel too nauseated while in VR, you might set up a mental association that'll take even longer to break. Relax and take your time to enjoy it in small doses.
Oh, and make sure your Rift is set up carefully, use the correct FoV and IPD settings, avoid any sudden movements, and it'll go a lot easier on you.
You'll quickly build up a tolerance, if my own experience, and others I've heard from, is any guide. Don't overdo it, just 10-15 minutes a day for a week or so and you'll be fine in no time.
Your wife may even find that a few more controlled sessions on the Rift actually improves her motion sickness in other contexts too. Some people have reported curing their own car sickness that way.
Finding it hard to follow your train of thought, but if I understand you right...
There are multiple factors, not one "root cause". Orbital precession isn't enough by itself, but when combined with orbital eccentricity and obliquity AND favourable topology, then you get an ice age. That's why they don't occur at *every* orbital cycle - and why they can sometimes occur between cycles (e.g. if intense volcanism causes enough cooling to trigger an ice age by itself).
If you want a specific example, try this paper, which describes how, 116,000 years ago, a pattern of ice sheet formation and melting every few thousand years was triggered by the Bering Strait being shallow enough that whenever sea levels lowered sufficiently through ice formation, the Strait closed, which changed the salinity mixing of the Pacific and Atlantic oceans. This intensified the Atlantic's meridional current, which warmed parts of Greenland and North America sufficiently to melt enough ice to re-open the Strait - and the pattern repeated.
This pattern was eventually broken 34,000 years ago when (yes) we reached a point in our orbital cycle that kept temperatures cool enough, and the Strait closed long enough, to stabilise the climate, so that when it opened once more 10,000 years ago, the climate remained stable enough to allow our civilisation. So as you see, it's not so simple that there's a single "root cause" we can pin it on, but that doesn't mean we don't know what did it - we can see (and simulate) how multiple factors combined and interacted to result the ice ages we can see in the ice core record, which gives us a pretty solid explanation as to the causes of all the ice ages over the last 116,000 years.
The two are not linked. If we move off fossil fuels, our net CO2 emissions are cut to virtually zero, regardless of population (in fact, increased population acts as a carbon sink) or energy usage. Given enough cheap, carbon-free energy to distill seawater and power hydroponic stacks, we can support a far larger population if required.
Then all we have to worry about is excess waste heat, which will be a huge problem in 300-400 years. Though limiting ourselves to solar-derived energy can help a lot here.
* Intermittent Wi-Fi scanning for location (saves battery) * OpenGL ES 3.0 support * Bluetooth 4.0 LE and AVRCP 1.3 support * Autocompleting dialpad * Virtual surround sound
* SELinux MAC system support for the app sandbox * Better WPA2 EAP and Phase 2 authentication support * Hardware root of trust support * Modular DRM support (e.g. allows 1080p Netflix) * Hardware geofencing * Media muxer and VP8 encoding * And of course, further rendering and other optimisations
Google Translate didn't do an awesome job at that, but AFAICT it says we're not totally sure of all contributing factors, but puts it down to a combination of Milankovitch cycles, plate tectonics, topology changes that redirect air and water currents, and vulcanism.
Which are all described in the second link I gave, too. Like I was saying, most earth scientists have a pretty good idea of what causes ice ages. Orbital variations are often a significant factor (as evidenced by the timing correlations), but of course there are other factors too.
I don't think you could argue that "no one knows what caused the glacier periods" when we have identified numerous contributing causes that explain them all quite well. Are we 100% absolutely certain? No, nor can we be about anything (except mathematics), but the causes of glaciation are relatively well understood.
Three orbital variations contribute to interglacials... eccentricity.. obliquity.. precession.
There are other contributing factors of course, but orbital variations are the strongest and accepted explanation. From the first source:
Glacials and interglacials occur in fairly regular repeated cycles. The timing is governed to a large degree by predictable cyclic changes in Earth’s orbit
If you can cite studies supporting a better theory, or even studies throwing these studies into doubt, feel free. Or are you just going to fall back to the useless solipsist argument of "nothing is real, there are no absolutes"? Which is fine for the philosophy department's coffee room, but will cut no ice in the real world.
Don't forget the oceans - they're more than twice the area of the ground, and six times the area of the deserts.
I'd like a cited study that suggests capturing 20% of the energy from 5% of the globe and releasing it at a city nearby instead will "throw the climate into far more chaos than some CO2 ever did". Rather than leaping to conclusions like it's an Olympic event.

It's cheaper because the oil tycoons aren't paying for all the costs of burning the stuff (they're actually getting huge tax breaks instead).

Bet you didn't know that when you reduce child mortality rates, population growth rates actually go down, not up.

Why, were you planning to use only Koush's Cast app? There are other ways to stream local content which still work fine, like tab casting from Chrome.
It didn't break tab casting from Chrome at all.
If you read the original post, it only breaks Koush's Cast app for Android, which worked around the whitelisting restrictions to cast content directly.
Hmm, semi-open $35 dongle from Google, vs 100% proprietary $200 box from Microsoft. Is that really a choice?

It seems to me that you have absolutely NO idea about what the paper actually says.

What's new about the profiles is that now they can be restricted from certain apps or actions (with some granularity), for parental control.
Other new features include:
* Intermittent Wi-Fi scanning for location (saves battery)
* OpenGL ES 3.0 support
* Bluetooth 4.0 LE and AVRCP 1.3 support
* Autocompleting dialpad
* Virtual surround sound
There's more under the hood changes:
* SELinux MAC system support for the app sandbox
* Better WPA2 EAP and Phase 2 authentication support
* Hardware root of trust support
* Modular DRM support (e.g. allows 1080p Netflix)
* Hardware geofencing
* Media muxer and VP8 encoding
* And of course, further rendering and other optimisations
Still, it's no ICS or Key Lime Pie.

You're right, temperature isn't rising for me either. Though that might simply be because the sun just set here.
More relevantly, yes, the temperature is still trending upwards, despite natural cycles that slow or reverse this over shorter periods of time.
Let me direct you to this pretty graph that you might be able to understand.
