Note that watch depth ratings are highly optimistic being based on static pressure only, being tested only when the watch is brand new and having no safety margins.
Cows graze around boulders and on slopes, where tractors can't work.
I suspect they will continue to do so. Some people will still want real meat even if the substitutes improve.
(Feeding cows corn & soybean meal is rather foolish, and is the real problem here.)
And AIUI we do this because the demand for meat outstrips what can be supplied by just eating the natural food available in areas where we can't grow crops.
So you just tax 10% of revenue, and call it a day.
If you tax revenue then you would disadvantage small buisnesses who do one stage of the production process and give a big advantage to large companies with the resources to vertically integrate so the revenue tax is only paid once.
You would also put your companies at a massive disadvantage against foreign companies operating in areas without a revenue tax.
With a traditional meter they know how much you used but not when and not on what.
A "smart meter" tells them the when. If the want to know "on what" they will need other sensors reporting to them.
What they really want of course is the ability to do "demand side mangement". To be able to cut off the highest peaks by turning off peoples freezer or AC for short periods.
AIUI a siphon needs BOTH gravity and air pressure.
Gravity makes water in the down side of the siphon move downwards. This reduces the pressure at the top of the siphon to less than atmospheric pressure. Which in turn allows atmospheric pressure to push water up the up side of the siphon.
Take away gravity and there is nothing to pull the water down the down side. Take away atmospheric pressure and there is nothing to push the water up the up side. Either way your siphon won't work.
Trouble is "Making IPv6 work" requires other people to deploy it. I dunno what things are like where you live but here in the UK the only access providers that offer IPv6 connectivity are the boutique ones.
It's not the direct overhead of the DRM, it's the way the drm is structured forcing the user to do things less efficiently. If the drm system only allows streaming then you have to push the data over whatever network you have at the time and place you want to watch and if you want to watch it more than once you have to push the data multiple times.
Without drm you can just download it once on the most economical connection you have available.
If Aereo wins, the cable companies would be able to save money by erecting Aereo-style antenna arrays for their cable feeds, bypassing payments to the networks.
I doubt it, Aereo's legal position relies on one antenna per user. That also means one data stream per user.
So switching to doing things aereo style would require a cable company to massively re-engineer things.
This assumes that either the seller is allowed to split the block or the price per IP for a/8 is comparable to the price per IP for a/8 block is comparable to the price per IP for the much smaller blocks you see sold on that site.
With IPv6 they are trying to allocate blocks in such a way that they almost never have to give a network a second block that is not continguous with it's initial block. So it should hopefully convege much closer to one block per multihomed network than IPv4 has.
Still the number of multihomed networks is only going to grow over time and whatever you do each such network is going to want at least one entry in the global routing table.
Hey! I thought the ipv4 address space was running out... hmmm.. guess not.
Or maybe the vendor in question are doing it to "justify" getting a larger allocation from the RIR, once IP space really runs out they can reconsider their policy.
ie it would take MIT 5 years to re-engineer their network to free up say half of their allocation
I call BS, it would only take that long if it was a low priority job. If they were told in no uncertain terms to sort it out or be kicked out of the internet I'm sure they could deal with it much quicker than that.
Why would you choose that option when we have a way of bypassing it?
Because people will do what is individally best for them, not what is best for the community as a whole.
If I want to run a server for the general public to access over the internet it needs to have an IPv4 address until such time as the vast majority of clients can reliablly access IPv6 servers (I would not consider teredo to be "reliable", it's overcomplicated and fights against NAT rather than working with it).
Similarly if I want my users to be able to access resources on the public internet I need IPv4 addresses for the intent side of my nat boxes until such time as the vast majority of servers are available on IPv6.
If I deploy IPv6 it will not change whether those systems need IPv4 addresses. To do that requires OTHER PEOPLE to deploy IPv6 which they are often unintertested in doing.
so we have another 5 years of eking out of old order before people REALLY have to take notice.
Possiblly much more than that.
XP and andriod 2.x are dying. They aren't dead yet but in a few years time their relavence will likely have declined to the level where website operators think it reasonable to stop supporting their default browsers. Once that happens we will be able to use SNI (and tell the holdouts still on XP to "use firefox or chrome damnit")
Once that happens it will be possible to put multiple SSL websites behind one IP reducing the IP demand on the hosting side. With end lusers put behind CGN, SSL web hosting running multiple sites per IP and basic VM hosting using front end load balancers to let them share IPv4 IPs it should be possible to keep IPv4 going for a long time.
One interesting question is what price will IPv4 addresses reach, currently it seems to vary from about $7-$25 per address depending on block size (http://ipv4auctions.bstocksolutions.com/)
ISPs NEED to provide their customers with the ability to access resources on the IPv4 internet from end devices that only support IPv4. For most ISPs (massive ones that have problems with running out of private v4 space excepted) who can't give all their customers public IPs the easiest way to achive that will be to deploy NAT44. Once they have deployed the NAT44 there is no real pressure to get arround to deploying IPv6 as well.
Some ISPs may consider building a v6 only access network and using ds-lite instead of using traditional NAT44. There are certainly advantages to that approach but I suspect it will be the exception rather than the rule and mostly seen with ISPs who are building new networks from scratch.
We may see some NAT64 (especially on mobile) but as well as philosophical objections (messing with dns) it has the big problem that it can't support v4 only client devices.
Comcast is in the unusual position that they are so damn big they have run out of space in net10 leaving them with two painful options, move to IPv6 or "federate" their network so they can reuse the same private IPs in different places.
The bigger question is was this "anonymous caller" a real member of the public reporting a real crime or was it a cop laundering illegally obtained evidence.
A key principal of the US legal system is that if the cops break the law while obtaining evidence the evidence so-obtained and anything derived from it is thrown out. The idea of this is to keep the police following the law. The problem is that rather than actually follow the law the cops and spooks engage in "paralell construction" where illegal evidence is used to decide who to target but a "clean" chain of evidence is built up later to justify the arrest.
1: Pretty much every hardware RNG will have biases in the output. So you still tend to end up needing a prng-like layer to clean things up. 2: If the RNG is integrated into a processor or similar (which is the only way it will gain mass deployment) then it raises the question of whether you trust the processor vendor to implement it properly and without the influence of the spooks. The more paranoid members of the crypto community don't trust hardware vendors that much.
Even if it does happen that they cut it off from time to time the pipeline may still be valuable to russia. If russia has multiple export routes to/via different countries then the impact of any one route being cut (for example exports to europe could potentially be cut off by sanctions over the ukraine situation) is reduced.
We may see a model similar to openssh where the core code in openbsd is kept free of "portability goop" and then a seperate group maintains a "portable" version based on the openbsd version.
Given the cost of using the court system it simply isn't worth suing for small ammounts of money. Small claims court helps to an extent but for most people it still won't be worth if the value of the damage is less than a few hundred dollars (and if you value your time and are well paid quite possiblly not even then).
Sometimes a company can do a small ammount of damage to a lot of people. If a company with a million customers screws each of them out of $10 then they have dishonestly gained $10 million. That is clearly a sum where it is worth going to the expense of using proper court procedures to consider the case but only if all the damage can be considered at once in one court case. Hence the reason for class actions.
Having said that while I like the principle of class action lawsuits I don't agree with the practice of paying victims damages by using vouchers which will encourage them to go back to the company that screwed them rather than something that can easilly be spent anywhere.
There is also the question of how do you know for sure that the socket is BASE-T ethernet (and not ethernet with a propietary physical layer or something else entirely) until you connect to that.
Having said that I suspect that the chances of finding a socket in a car carrying an interface so fragile that base-t ethernet could blow it up are pretty low.

It's possible with at least some ethernet BASE-T Phys to operate without transformers. Most ethernet transformers are 1:1 ratio anyway.
