Branch prediction without speculative execution does not make any sense.
Speculative execution without branch prediction also does not make sense except in very special applications. It exists as eager execution but costs so much more power than branch prediction that it is not worth it except in applications where performance at any cost is needed.
They ignored the privilege check when accessing the cache (MELTDOWN)!
The privilege check was ignored (not done) at the load but was caught at instruction retirement like other faults. This had the disastrous side effect of allowing the processor to execute speculative instructions on privileged data while not causing a fault because the speculated instructions were never committed.
To me the odd thing was that AMD did not suffer from the same problem. What made them decide to check privilege levels at the load instruction instead of at instruction retirement?
So you're saying "plea bargaining" should be eliminated and perps tried based solely on the crime committed. No one should be allowed to "plea down" their charge, even when there is overwhelming evidence against them.
Wouldn't this end up with MORE time stacked onto the these prisoner's sentence? Wouldn't this end up with MORE cost to the U.S. taxpayers for court time and incarceration time?
What is the benefit of your plan?
With terms like "federal Gulag" and "kangaroo court" it sounds like someone you know has been convicted of a lesser charge. So should they then face a jury trial for their original crime and end up serving more time?
It could cost a hell of a lot more. The benefit would be assigning a more accurate value to the cost of enforcing the law. As it is, most of this burden has been shifted and hidden.
I would go further. Every offense, even traffic offenses, should have the right to a jury trial. If the offense does not warranty a jury trial, then the law should be reconsidered. Too many (most) municipalities use civil infractions for revenue alienating much of the population.
And with 20 times as many jury trials, more common citizens would get to experience first hand what a farce our "justice" system is.
Or are you trying to imply that 95% of people incarcerated by the Feds never broke the Law? Which sounds extremely implausible.
95% did not break the law that they plied guilty to.
Think this through - Putin & friends were able to thwart the election for abut $100K in ads, and Hillary with her $1BN budget couldn't overcome that influence/meddling?
Was that by thwarting the election with Hillary's dirty laundry? The DNC hack was the only thing I found interesting but I don't get news from the various internet social sites. Getting it second hand is bad enough.
I expect clamping down on social media will do more damage than the election shenanigans. The media has steered elections forever and now they have another tool and excuse.
IBM sold its business to Global Foundries. Global Foundries has announced they won't develop 7nm to compete with TSMC. Intel has delayed its 7nm process because of difficulties.
It is not quite that simple. The various companies do not identify processes by feature size in the same way so the Samsung and TSMC 7nm processes are comparable to Intel's 10nm process. And even with that, what matters is cost per transistor which is linked with density but also depends on other things.
Several houses share a transformer now, and in the future several outlets will share a USB power supply, and for the same reason, it will be cheaper and more efficient.
It will not be cheaper and more efficient because of higher copper losses and poorer regulation.
The poorer regulation will require an impedance transformation at the USB socket and if that is included, then it might as well be an AC to DC conversion avoiding the whole problem.
He means that as far as most US consumers are concerned, it is split-phase 240 volts AC with two hots, a neutral, and a ground.
It should not be called two-phase to avoid confusion with the actual two-phase legacy system which are still in use in some places where the phases are at 90 degrees.
What refugees have the problem of database tampering?
The ones who have their currency devalued by hyperinflation have problems. Currency is a database of stored value certified and exclusively controlled by the government which controls it. A blockchain prevents a centralized authority from "minting" new currency devaluing existing currency at their whim.
Higher weight. Here is a typical example of probably the most common German car:
VW Golf 1, 750-805 kg kerb weight, 50-70 hp. VW Golf 7, 1205-1540 kg kerb weight, 85-180 hp (non-GTI version).
Add to this the general population becoming heavier and you'll have your answer.
At least in the US you can attribute part of this to EPA regulations which require higher fuel efficiencies on lighter vehicles. Build a heavier vehicle may be less expensive than a more efficient one.
Why on earth would you need a day of storage? And isn't France linked directly to the grids of neighboring countries?
Now apply that idea to all of France's neighboring countries as well. With that concept, nobody needs any storage at all because it is always day and the wind always blows somewhere else.
Well, yeah, that's my point. The traffic could be treated exactly the same, but the peering might be constrained. This is not a violation of NN.
It is a distinction without a difference when the ISP controls the routing. It is an old peering strategy to deliberately route selected traffic through or away from a specific peering or transit connection to achieve a desired result.
No, If I want to use netflix there is no reason the ISP should get to denigrate it's performance vs youtube or any other video service
Is all traffic really "created equal"? What if the firefighters or police need to send a video of something they are working on — and the local tower is faced with the dilemma of whether to drop your or their packets? They can't analyze the stream's content (even if it weren't encrypted), but they do know the endpoints.
YouTube, being pure entertainment, loses...
What if the firefighters are using YouTube to distribute real time video coverage of the fire to themselves?
There are ways for traffic shaping to handle situations like these and give the customers exactly what they purchased.
No. Each TCP connection has it's own congestion control and the TCP algorithm for each connection is responsible for throttling itself. So if I have 5 active connections from my machine to www.slashdot.org and one connection to tacotime.com; tacotime only gets 1/5th of the pie, not 1/2 of the pie.
There is no reason other than complexity that traffic shaping cannot aggregate separate connections to the same IP.
Yup, this. They made such a huge complaint about peering agreements and cost as the focus.
Even if they had other content on the box, it still greatly limited upstream bandwidth (including for that other content!) and reduced those magical peering costs. It's not like the demand for that other 'scary' data goes away either...ISPs need to stop trying to play favorites and actually deliver the experience their customers are seeking.
I have always assumed that ISPs want to limit upstream bandwidth of their consumer users to sell it to customers that provide content but there are other reasons for consumer customers to prefer asymmetrical upload and download speeds.
For what it is worth, my best home internet experiences were with symmetrical low latency technologies like SDSL even if I was not taking advantage of the higher upload speeds.
Some end-user ISPs are considering using highly controlled multicast ABR to efficiently deliver live content to their own subscribers, but it is unlikely that multicast will ever be distributed across the Internet.
As I recall, AT&T U-Verse uses multicast to deliver U-Verse TV content to their subscribers.

Wait.... don't cigarette manufacturers have a major stake in e-cigs too? How could they not?
The problem is that they don't have a monopoly on e-cigs. It is too easy for others to enter the market.
Second they generate money that can be used to pay for the extra health costs associated with smoking.
Is that like how government lottery sales increased school funding? It is too bad that money is fungible.
America used to have lots of friends in the world.
Nations never have friends. They have interests.

And Itanium also provided less performance because the magic compilers it relied on never achieved the predicted level of performance.

By their own actions, convicted felons doing time are not part of regular society, ...
Then do not let them out of prison.

Franken-Algorithms? Just wait until they are used by law enforcement and the court system which is already starting.
I read that as, "They have made improvements to paper over future vulnerabilities."
Why would Facebook and Twitter admit that their business is a threat to democracy?
Congress has a special language. Let me translate.
"Those are nice partisan elections you have there. It would be a shame if something happened to them."
Well, I am glad you elucidated the fallacy in my argument so clearly without reaching any merits.

The IR was so weak though you had to sit within 3 feet of the TV. But, the purpose was to control a printer and 3 feet is plenty there.
The IR was made deliberately weak after schools complained about students sharing test answers.
