I have not posted for a few years but this one really has annoyed me enough to say something regarding these Brexit ads.
For a start there are no new elections or referendums so it's hardly trying to influence a vote, the Guardian (left wing) newspaper would love to have a second referendum and reverse the vote and is most likely why they have flagged this up.
I can see how not knowing who is paying for these ads may be a problem for some, but like I said there is no public vote coming up and therefore as far as a I know campaign financing rules do apply, besides I did not see the Guardian kick up a fuss when Soros donated £400,000 to reverse Brexit.
Finally a large chunk of Conservative (the governing party) MPs themselves have said the same thing that this advert is saying so how is this fake news?
If there was any semblance that there was democracy in the UK, it has pretty much has been laid to rest.
System calls where always slow because they used to be called via a software interrupt call.
SYSCALL is an in x64 instruction that speeds this up, introduced by AMD.
Speculative execution predates SYSCALL by about 5 years.
System calls are now slower because the kernel memory now has to be mapped and unmapped when the system call enters/leaves rather than be mapped all the time. This has to be done because memory that was marked as privledged can now be accessed by user programs i.e. memory protection no longer works and the only fix for the problem is to unmap the memory.
Speculative execution does n't mean we have have this problem, AMD managed to do it fine. No one can say this is by design, if it is by design then it should be documented since 1995 that the MMU protection can be bypassed.
For power users "Fast enough" is not the reason people are not upgrading, I used to do a 3 year replacement cycle and each time get a machine at least twice as fast as my previous one. My current machine is well over five years old and other than for tasks that can take advantage of a large number of cores any upgrade will get me around a 50% performance increase, which makes its just not worth it.
I think that is unfair because Visual Studio can be used for a lot of different things. Why would anyone using VS to develop Windows Apps for example need to have knowledge of Expression Studio?
If a potential customer does n't even know that the product exists, especially one who uses their other development tools thats a big massive fail in my book.
I'd like to see what happens when the sellers stop fulfilling orders. Plus how long before someone brings out a sniping tool for customers to purchase items when at the bottom of the curve?
Someone mentioned CISC, as if that beat out RISC? It didn't. Under the hood, modern x86 CPUs actually translate each x86 instruction to several RISC instructions. So why not just use the actual RISC instruction set directly? One argument in favor of the x86 instruction set is that it is denser. Takes fewer bytes than the equivalent action in RISC instructions. Perhaps, but that's accidental. If that is such a valuable property, ought to create a new instruction set that is optimized for code density. Then, as if x86 wasn't CISC enough, they rolled out the MMX, SSE, SSE2, SSE3, SSE4 additions.
This is n't the case, the only x86 processor that converted x86 instructions to RISC instructions was the AMD K5. Infact even in a RISC architecures the instruction decode stage expands out the instruction and this is what happens on a modern x86 processor.
The complexity in a modern processor is not in the instruction decode, but the multiple execution units.
I doubt it would add that much considering you already have to implement Tomasulo to go superscaler, it could be added onto that relatively easily. Of course it will add more circuitry and I agree Intel will have problems making something as low power as the current crop of ARM chips however when we get to something that is say the midpoint between an A9 and i3, Intel will be able to compete easily and also have its process advantage. It could easily be a case of ARM winning the battle and losing the war.
And there are far more 8-bit and 16-bit CPUs that use CISC instruction sets than ARM chips. The quantities mean nothing, it is who is making the most money and Intel certainly won that one.
Any superscaler processor is going to be doing instruction conversion, this includes RISC instruction set processors. The micro-ops in Intel processors convert to are less than RISC instructions. Once you start implementing things like Tomasulo the traditional advantages of RISC are eroded. If this was n't the case Intel would have never been able to leverage their process advantage to get better performance whilst retaining the x86 instruction set.
In a high performance processor instruction set is irrelavant since 80%+ of the die area is cache any way.
After finding out there are people buying spell casting services overy ebay in their thousands this is not surprising at all. A fool and his/her money is quickly seperated.
Um, last I checked a millimeter is pretty small. I can roll up all sorts of things to a reasonably thin degree which are much thicker than that(including one of those schnazzy silicone gel keyboard things).
It's a transparent flexible touch surface...and you're complaining because it's as thick as card stock?
Even 0.5mm overhead projector film is pretty hard stuff, silicon gel is very low density compared to plastic films as is card. I would expect a rolled diameter to be around 25-30cm which is fine for the 167", but a bit much for the small 30" versions.
It's interesting that they seem to just be going after the 10" tablets. Samsung make 7" tablets too, why did Apple not get an injunction on those too? Or is that basically they do not want anything that could compete with an Ipad be sold?
The number of nodes and processing power per node is meaningless unless they can connect them together in a similar fashion to the brain, sure they mention a "brain like" arrangement but the reason our brains are so sophisticated is not due to processing power but due to organisation. Brains are slow, really really slow but the parallelism and connectivity is beyond anything we can build at the moment and that is why we keep on failing on AI. An example is adding two numbers together, easy to do for a processor yet difficult to do using neural nets.
The reason this is the case is because current AI simulates a neural network as a program, you would have to produce chips which where actual neural networks the problem however is the interconnects which is in an order of magnitude more complicated compared to anything we can currently create. In fact the brain is quite slow, but its organization is what makes it powerful.
Call me stupid but how is this an invasion of privacy, it's not like information regarding your drunkenness is being passed over to the authorities.
Mark Hinkle, chairman of the Libertarian National Committee, fears the devices could evolve like seat belts — introduced as voluntary safety features that become lawfully enforced.
Oh yes those evil seat belts made mandatory because they save peoples lives, damn evil big government regulating car safety . Has it come to the point where there has to be a knee-jerk reaction to everything just for the sake of it?
The components may well cost 35$, but I'm sure they excluded the price of the PCB and the machine time for mounting the components onto the PCB, thats a big chunk of money right there. Then you've got the assembly, logistics and distribution costs so that even with cheap indian labour I'm sure you'ill be much closer to 70$ than 35$.
In sort its easy for the guys in the lab to look at the BOM and say 35$, but the reality is somewhat different.
My last two Nokia phones have been an absolute disaster, the first a 6600 fold locks up if you press the 6 key, thats right you can't use the 6 key. It's a common fault and and seems like one of those bugs that is so bizzare that nokia have n't been able to fix it because it does n't affect every phone. I then made the mistake of getting a N97 Mini and I can honestly say it will be my last Nokia phone, the CPU is so under powered its like a sick joke and the phone interface is terrible.
There was a time when you knew getting a Nokia meant a quality phone, I'm sorry to say that is n't the case anymore.
You're right about mentioning tolerances because batteries need to be held tightly in place hence the spring, however the spring is also to take into account that batteries are not manufactured to tight tolerances themselves and I've personally have experienced problems in certain devices with batteries not fitting easily due to being slightly longer.
Maybe they are using some kind of foam like material instead of a spring but I just can't see how this can be as robust.

Those hardly used instructions probably use less than 0.1% of the CPU die, that is because they are microcoded instructions and run hideously slow.
Someone mentioned CISC, as if that beat out RISC? It didn't. Under the hood, modern x86 CPUs actually translate each x86 instruction to several RISC instructions. So why not just use the actual RISC instruction set directly? One argument in favor of the x86 instruction set is that it is denser. Takes fewer bytes than the equivalent action in RISC instructions.

And how much money do you think ARM makes on that $10 part?
And there are far more 8-bit and 16-bit CPUs that use CISC instruction sets than ARM chips. The quantities mean nothing, it is who is making the most money and Intel certainly won that one.

This is called business, using whatever advantage you have to compete against a competitor. Last time I checked Intel was a business.
Wow sounds very secure, hopefully they did n't decide to go with ROT-13 twice.
Um, last I checked a millimeter is pretty small. I can roll up all sorts of things to a reasonably thin degree which are much thicker than that(including one of those schnazzy silicone gel keyboard things).

I would imagine any film above 1mm in thickness would be pretty hard to roll up into anything resembling a reasonable diameter.
It's interesting that they seem to just be going after the 10" tablets. Samsung make 7" tablets too, why did Apple not get an injunction on those too? Or is that basically they do not want anything that could compete with an Ipad be sold?

Would be better but would not even come close to the human brain, which in the cerebral cortex has roughly a billion synapses per cubic millimeter.
The reason this is the case is because current AI simulates a neural network as a program, you would have to produce chips which where actual neural networks the problem however is the interconnects which is in an order of magnitude more complicated compared to anything we can currently create.
