AMD chips are, according to AMD, vulnerable to a bounds check bypass related to speculative execution. In the details, they say "Resolved by software / OS updates to be made available by system vendors and manufacturers."
They do NOT say they are immune to the branch target injection vulnerability either. The say the following which is much less reassuring: "Differences in AMD architecture mean there is a near zero risk of exploitation of this variant."
>> Would I really have to go and set a registry key myself just to get updates again?
If you have manually removed the AV software that ships with the OS and have no other AV product installed, then yes you will need to set the registry key yourself.
I seem to recall a lease was the only way you could get an EV-1 or the electric ford ranger unless you were doing fleet sales. Were the electric Rav4's sold or leased?
You misunderstand; I'm not playing the idiot. I'm genuinely curious if specific effects of global warming caused this, and if so can they be replicated intentionally. Hurricanes cost billions. That is not a small market opportunity.
The Arab spring was predicted, but the predictions were discounted because they were unbelievable. We trusted hindsight instead of the data.
I don't recall the exact methodology, but it's something about the population distribution and unemployment. My recollection is that it's something about more people unemployed people between 15 and 25 than employed 30+ that it rolls up with a very strong correlation. Let me see if I can dig up the reference.
I'm curious to know to what extent climate change is responsible for the 2005-2014 pause in major hurricanes hitting the US. Is this the branch of science that could answer that?
I have an tangentially related question. How is it that I can get an E-packet delivery from China for less than the cost of first-class mailing the same item within the US?

I respectfully disagree with this paper's definition of Wisdom.
This study is measuring empathy, not Wisdom. Empathy is being able to place yourself in someone else' shoes. Wisdom is being able to predict the consequences of decisions in advance and use those predictions to make decisions.
Given the preposterous number of tote-the-note car lots, payday loan shops, and Tobacco/Beer/Crackpipe stores one can reasonably infer that wisdom strongly negatively correlates with decreases in social class.
Perhaps the word "wisdom" means something different in Canadian English?
Mod parent up. I've had an HP LaserJet 6p for a decade now, and it was used for who knows how long when I got it. I've put one toner cartridge for it in that time and it just works.
I would have paid for the full retail cost of this printer at three times over in ink cartridges in that same time period.
If you don't use an inkjet a lot the cartridges rot. Laser printer master race.
I have two issues with this that are straight show-stoppers.
1. 100% "pre-mined". The issuers start with literally all the money. 2. Centralized control. The blockchain/database has been "reset" a couple of times during the alpha to recover lost coins.
I love the scalability of this idea, but they've failed utterly at decentralizing. The lack of single authority is not a bug in Bitcoin; it's a feature. If I wanted an unaccountable organization to control the money I'd use Euros, not Iota.
>> Once sold, the money would go to an account held at the Treasury Executive Office for Asset Forfeiture.
Through a process called revenue sharing, a portion of these dollars (>80%) can flow back out of the treasury and into the state or local law enforcement agency that executed the seizure.
If that sounds fundamentally wrong and rife with the opportunity for abuse, congratulations. It appears you are paying attention.
>> I'll use bitcoin >> When I don't need any account or computer to use it and can carry it to the store in a sack.
You're looking for the Casascius physical bitcoins, from the first generation when they were pre-loaded with BTC. It was a very good idea for exactly the reason you describe.
At today's prices I'd be concerned about counterfeiting though.
The idea to force decentralized mining is not a new one; it was the basis for choosing the Scrypt encryption algorithm behind LiteCoin. Unfortunately some clever wogs came along and figured out how to make an asic to do that work and now it's centralized too.
I am working to decentralize mining by the only way I know how. I'm mining. I dropped half a BTC on miners earlier this month, and will spend many more if the company successfully delivers this batch. It's not an elegant solution, but it's what I can do for now.
Candidly I don't think you'll see non-asic-able cpu or gpu mining in the main bitcoin blockchain. That would require a fork, and the miners make that decision. It is not in their financial interest to make that choice.
The parent must have missed this rather salient point.
Perhaps one day some enterprising security research will pop into one of these publishers and show us where the money is actually going. It appears that it isn't anyone involved in the scientifically valuable work. I grok that rent and hosting aren't free, but they certainly aren't thousands of dollars per article either.
This is a pretty easy DIY repair, if you are so inclined.
Remove the two pentalobular screws and gingerly open the phone with a guitar pick.
< strikethrough>Smash it with a hammer and replace with android</strikethrough>
The battery is held in with two adhesive strips, but there is a trick to removing it. at the bottom of the battery is a little black tab. Peel that off of the battery. The adhesive strips are like the 3m command adhesives, and that little tab is what you carefully pull to remove the adhesive without violence.
The new battery is about $10, and the adhesive strips are about $4.
The reason Apple wanted to replace your screen < strikethrough>aside from ludicrous profit</strikethrough> is that popping the guts out of the case requires gently prying on the edge of the screen. If there is a crack there is a non-trivial chance of borking the whole screen.
Shameless plug for Samsung Phones here. I can do a glass-only screen repair on a Samsung in 20 minutes for $15 and never pick up a screwdriver.
You are right that robots can be used for exploration dramatically cheaper than humans.
To me though, there are fundamental limitations to robotic exploration that can't be ignored. Robots are truly fantastic at exploring what they are designed to explore, but they fall flat in a bunch of ways.
For example, on Mars we've discovered that dust-devils are a fairly common occurrence. It took 5 robotic missions to get an inkling of that, and we didn't get a picture of one until mission 7. We didn't see it because we didn't have motion-triggered imaging until the newest robots because we didn't expect motion. A human would have seen it, said "hey, check that out", and snapped a picture.
Terrain "feel" is another example. We look at rover images and motor driver current graphs to try to understand what kind of terrain the rover is crossing. A human can observe "It's squishy here".
Robots fall terribly flat when you compare distances. A human, even in an EVA suit, can cover kilometers in a day. Our best robots cover kilometers per year.
When they get where they are going, the robots are still limited. The MSL carried a rock sample in its grinder for weeks because it was stuck and wouldn't fall out into the instrument. A human could have tapped or scraped that out. This dexterity has other benefits too. It's been 40 years since we dropped our first robot on Mars, and we still don't have the ability to flip over a plate-sized rock or dig a hole more than an inch deep.
Last but not least is Inspiration: This is important even though it's touchy-feely. Robots don't inspire human dreams the way manned exploration does. Those dreams are important, and I can prove it. Tomorrow a recycled rocket carrying a recycled spacecraft is going to fly to the ISS because one guy was inspired by the Apollo program and he really wants to go to Mars. Rovers don't do that.
>> This is the result of the last two idiots in office that decided to cancel the space shuttle program
No, unfortunately the blame goes much further back than the last two. NASA has been warning Congress about the end of the Space Shuttle program and begging for funding to replace it since the 90s.
That can has been kicked so many times it needs its own odometer.

Do you have a source for that? The linked page is all I can find on it.
According to AMD, AMD is vulnerable to one variant of the attack, and possibly vulnerable to a second variant.

Kb4056894 does include the mitigation for the rogue data cache load and the software portion of the mitigation for branch target injection.
Microsoft describes this KB as the resolution for this issue on Windows 7 here:
https://portal.msrc.microsoft....
Note that to be fully protected from branch target injection you also need a CPU Microcode update from your hardware vendor.

Today it's 13000PH/s
The antminer s9 specifications are here:
https://shop.bitmain.com/speci...
100 watts per terahash is 100 Kw per petahash.
I'm no multiplication genius, but doesn't 13,000 PH 100Kw/Ph multiply out to 1.3Gw ignoring cooling?
The estimate, with cooling, should be within an order of magnitude of that. Anything higher should be viewed with some skepticism.
