From Nature communications: Patterns of island change and persistence offer alternate adaptation pathways for atoll nations
Paul S. Kench, Murray R. Ford & Susan D. Owen
Abstract Sea-level rise and climatic change threaten the existence of atoll nations. Inundation and erosion are expected to render islands uninhabitable over the next century, forcing human migration. Here we present analysis of shoreline change in all 101 islands in the Pacific atoll nation of Tuvalu. Using remotely sensed data, change is analysed over the past four decades, a period when local sea level has risen at twice the global average (~3.90±0.4mm.yr1). Results highlight a net increase in land area in Tuvalu of 73.5ha (2.9%), despite sea-level rise, and land area increase in eight of nine atolls. Island change has lacked uniformity with 74% increasing and 27% decreasing in size. Results challenge perceptions of island loss, showing islands are dynamic features that will persist as sites for habitation over the next century, presenting alternate opportunities for adaptation that embrace the heterogeneity of island types and their dynamics.
The problem is less with growing enough food than how much habitat destruction is required.
The higher the yield, the lower the number of acres needed, and more land can be returned to a natural state.
If you want to help the natural environment to help prevent more species from going extinct, then you want to reduce our impact on it. Reducing the amount of land we use for agriculture is the first place to start.
Anything that makes agriculture less productive means more land is required and that means more habitat destruction.
Reasonably sure that you can Google XXX for any high volume smartphone and find out that someone somewhere has had some dead on arrival anecdotal evidence for you. Law of large numbers etc.
On the other hand, if you look at satisfaction stats you'll find all current and recent (and not so recent) iPhones at the top of the list consistently, which gives the lie to your anecdotal evidence based on an experiment of N units where N is 1.
Given the size and numbers, is $250 million more or less than the cost of keeping their infrastructure up to date?
And even after this costly mistake by a vendor, just keeping their systems tightly locked down and having much better controls over who or what gets plugged into their network may be far cheaper than updating everything.
Given that they were back up and running quickly, it does appear that they have everything locked down and backed up. I expect they knew what the risks where and are and will update their procedures appropriately.
The more apropos question is whether it is overall cheaper to have privately financed autonomous vehicles providing the equivalent to public transit. Will city and state governments discover that they can simply stop expanding public transit (and possibly scale it back over time) as lower cost and more efficient use of the roads can be found with autonomous vehicles?
By some accounts, the number of horses in the US today exceeds that of the late 1800's and early 1900's. They just (mostly) don't get used for transportation to and from work etc.
So you don't think that LIDAR will follow the example of other consumer electronics? E.g. the smartphone you have in your pocket? What do you think an iPhone X would have cost to build in 2008?
Once it starts getting into high production prices will start to fall and functionality will increase. There has not been any electronics based product ever that did not follow that pattern.
Except that Uber is currently highly subsidizing their service in an attempt to establish themselves as the predominant provider.
It is likely that they will have to reduce their subsidies in the long run, and most likely they will do that simply by moving more people to autonomous rides where (possibly) the existing fare structure could cover their cost of providing the service.
Of course, there will be bumps and ups and downs in pricing all along the way as other services jockey for market share (some of which will be well funded, e.g. Lyft.)
The old 80/20 rule applies here. The first 80% of the usage will be by people that don't live in or need to drive in any of the conditions you describe. And for the 20% of the people that do the existing solutions will work perfectly fine.
There is simply no reason for the 80% that can use it as soon as available to wait until it can also be used by the last 20%.
It is lucky for us it was the local police that caught him. The FBI is convinced that they are going dark because of encryption so would have just put out a press release calling for backdoors in cell phones and web etc.
It is reasonably obvious that despite encryption which is shutting some traditional doors that the cops were used to looking through, that there is a plethora of new data that can be used instead.
Memcached implements a key-value store. The DDOS first put a large value with a known key into the server to be exploited, then sends spoofed UDP packets to it requesting the key.
Once you clear the cache, the server cannot be exploited again until a new key-value is stored. The exploit cannot use other data that might be on the server because it does not know what the keys are.
A possibly safer kill-switch would simply upload a new small value for the key to any server sending you data. It will continue to send you that value instead of the much larger one loaded for the exploit. A very small (under 50 bytes?) UDP packet is better than the very large amount of data currently being sent (I think 700kbytes?) Reduces the amplification factor to close to zero.
Your insurance company wants your license because they are insuring you driving your car.
If you are not driving your car, then the insurance company that is insuring your self-driving car will want to know how reliable that brand of self-driving car is etc, but won't care about who the car is driving around.
I think we can assume that the self-driving car manufacturers, insurance companies, and state regulators will sort this out long before you show up at the dealer to buy one and get it insured.
Or more likely "... in order to prevent devices from unintentionally shutting down due to abuses batteries that are degraded by bursts of high current demand. Batteries that did not meet their design lifetime because of daily 90-95% discharge/recharge cycles."
Don't abuse your battery with repeated deep discharge cycles and it will last a lot longer. And you probably will never see your iPhone getting slowed down to allow it to continue functioning at all.
Of course, Apple could never come out and blame customers for abusing their phones.
"While climate caterwaulers are ridiculously complaining the Trump administration is blocking new Earth observing satellites from being launched, we find one is on the launch schedule for November 10th. From NOAA – The launch of JPSS-1, the first in a series of NOAA’s four next-generation operational polar-orbiting weather satellites that will give scientists the most advanced tools to aid in weather forecasting and earth observations, is scheduled for November 10 at 1:47 a.m. PST from Vandenberg Air Force Base in California."
"But as NASA’s leader of the U.S. Science Team on one of the best satellite instruments developed for monitoring sea ice, I can tell you we will not lose our ability to monitor sea ice.
Admittedly, the premature failure of the Defense Department’s DMSP F17 and F19 satellites has definitely reduced the number of times a day we can measure the polar regions."
I use Apple Pay and get my ding to say it is authorized in about a quarter of a second or less. I usually decline the receipt so I'm walking to the door in 1-2 seconds.
Costco Canada does tap at the till and for their gas stations also do tap. That changes the time to get started pumping from minutes to seconds. I have arrived after somebody was already at the pump and started filling, got to about 10-15 liters before the other person started pumping.
For corporate gmail, the "can you give me a new password" request goes to the administrator of your corporate gmail. It does not go to Google.
That raises the bar slightly. First the hackers have to know who that is. Second they have to determine what the practices and procedures for making the request are for your organization and third what a possible way to subvert them are. Should be different for all organizations.
I suspect Gmail (corporate version) is more secure than what most organizations can implement and support.
The only problem with hardware 2-factor is how to incorporate it into mobile. Is the phone itself a sufficient token (if coupled with something like TouchID to verify the user?)
The Fido hardware keys are a simple way to secure desktop access.
Yes, there are a bunch of jobs that have the same label.
But in most cases the same "insert job title here" either requires vastly different skills and / or does something only vaguely resembling what their counterpart did 100+ years ago.
Lawyers come close. But I would still not hire a lawyer fresh from 1900 if he was available now.

Our model knows more than your reality.
Of more interest is whether over fished stocks would be in (as much) trouble if not over fished.
Mythical Man Month was published in 1975. And, yes, clearly, not much has changed.
This is an old post describing how coral atolls float and effectively keep pace with the rise and fall of sea level.

And there have been numerous recent reports showing that island (e.g. Tuvalu) is indeed growing.
