Did you really just try to use a 70s era PDIP processor as a counterpoint to AMD's incorporation of a modern memory controller into a CPU die? Thats like saying that NASA's space shuttle's ability to be re-used was nothing new because airplanes were always reused.
Well it IS done with jump instructions, but as few as possible because the branch penalty is usually high (especially on an x86). If you don't use the goto statement then your program is more abstract, and structures like loops can be more easily optimised by the compiler to use as few branches as possible. Not to mention things architecture-specific like ARM's condition codes which can turn a loop with multiple if-else statements into a block of code with only one branch instruction.
You are killing me. Anyone with any ISA experience knows that branch PREDICTION has a high cost associated with it in cases where the predictor does not match the situation. While, granted, IF X GOTO Y logic can damage optimization for a known prediction scheme, a simple GOTO has almost know cost associated with it (unless you have a cache miss or something, which you would have in any case, not just with GOTO). And loop unrolling is swell, but most good compilers are capable of unrolling loops regardless of how they are written. And most good compilers will actually convert your evaluations to match whatever branch prediction scheme is in place.
In practice the only way to gain access to the locations secured by physical keys is to steal them, doing it without the persons knowledge means stealing them, copying them and returning them without the persons knowledge.
It may be possible to crack the encryption (if there is any, many such secure systems claim to have encryption but do not) on this RFID technology at range with an antenna that can not be seen.
Physically tapping wires is MUCH more time consuming than some script kiddie tracking registers for a video game. And considering they are probably using SMT BGA/CGA chips, you will probably have to start soldering to leads on the board without really knowing what pins they are connecting to (unless you have a sweet X-Ray machine like they use for QA & solder rework applications). AND NONE OF THIS GETS YOU ANY CLOSER TO READING THE EVENT LOG FROM THE CHIP, so who cares if you can read the sensors? (Unless you want to design an observer unit to monitor future activity)
There is no good way of getting log information out if the company (presumably) does not want you to get it out. You could open of the IC storing the information and start modding, but this is an extremely specialized task requiring a very expensive lab and years of experience. Good luck.
Oddly, in the future (when this technology is available): 2000 / 1000 = 5
Not to mention that if 1000Gb/s connections are widely commercially available today, I have to assume that faster connections are available for specialized purposes.
Sadly this cannot be conveniently used in more different western languages (I believe you will find most Chinese dialects have shared grammatical standards), because word order and grammatical standards are based on spoken language.
While technically true (the same way an English speaker could read a French newspaper without knowing a word of spoken French), written Korean is totally different than written Chinese. So I'm not sure why you selected those two...
nobody has the solution he requested, because the solution he requested is stupid.
Amen.
There is no advantage in the world to writing a specific bit to a specific location, when physical locations are already mapped byte-wise to an address space. Oh, you several single-bit data to write? Use XOR and do it like anyone who ever had to set/clear flags on a micro-controller does. And if this causes you to have to cache (gasp) seven bits of data waiting for the eighth, GOOD.
PS I doubt that there is a GP processor on the planet which does bit wise operations with a single-bit register. Maybe if you have a very weak computer from 1950...
Small caviat: You can measure the rate of mutation, not the rate of "evolution", as "evolution" is a hindsight-only type of observation (ie X trait was evolved, ie X trait now exists in a sizable fraction of the species population). "Evolution" is mankind's way of describing beneficial mutation, but benefits are hard to measure a priori:)
In the spirit of individuality and innovation, I vote we each create our own system of measurements, and use them exclusively. Six billion units of length, and no standard!
A) TFS states that the they are looking at protein folding, which can hardly be viewed probabilistically for a macro-scale (ie "in the aggregate").
B) Quantum mechanics deals extensively with uncertainty through models of superposition, which include probability functions.
PS I see what you are saying about the summary, it seems to imply that bubble sort is bad, but really it was just a poor use of well known methods (which presumably some beginner threw at a problem without thinking).
The point is that it is easily explained by a stupid programming move, and not by some conspiracy to list Microsoft's own product last. Oh, and this is Microsoft, so are we really surprised at the possibility of epic algorithmic mistakes?
And he spent "this kind of effort"
A) Because he had a few hours to kill.
B) Because he found it interesting.
C) Because he wanted to back up his blog story with actual tests.
D) All of the above.
Microsoft used bogus, non-static, comparisons of random numbers to "sort" the list, but they generated new, meaningless random numbers for every comparison. IE must have been the last entry, and had a 50% chance of the sort loop exiting the first time it was encountered (leaving it in the last position). IANAProgrammer and this is an obvious error to me. I thought TFA was going to be about a poorly seeded random number generator.
You did not have the money to live off your interest, and claim to not have had a job. This smacks of a lack of nth generational financial planning, not inflation. Inflation proofing is roughly no-risk investing. You cannot expect a whole family to live on a fortune for several generations without contributing to the fortune and not eventually have it expire. It is not, after all, infinite money.
And the parent was talking about the income gap, ie typical executives making 400+ times the income of their average employee, versus less that 40 times that of average employees fifty years ago.
Consumers wouldn't "see, care or understand the costs associated with the services they demand" regardless of who is paying for it. To quote wikipedia:
This government study showed that 21% to 23% of adult Americans were not "able to locate information in text", could not "make low-level inferences using printed materials", and were unable to "integrate easily identifiable pieces of information."
If >20% of people are incapable of reading a pamphlet for simple information, what fraction do you think will be able to comprehend which MRI scanner is worth a $600 equipment use fee, or even what a general physical should cost?
There are more grandmothers than 12-24 year old students? I doubt this, sir.
Anyway, if your grandmother can't handle a computer, what use will she ever have with an iPad? She does not want one. The only reason she will have one and pretend to like it is because you bought it for her. She secretly just wanted to go out to dinner with the family on her birthday, you insensitive clod.
PS TFA was what compared it to a netbook in the first place. The Apple staffer started it. So go burn him on a stake in protection of your vaunted un-released crap-slab.

It could be more secure, or less.

You are assuming you need the keys in the first place...
A time-variant RFID key would be significantly more secure. I just hope you don't drop your phone in your toilet.
Because I am worth more than the 0.001 cents they will get for selling my email to spammers ?
Since when did they ever do such a thing? Secondly, even if they did what is cynical about that?
lol.
Why don't you ask the robot?
I believe they were using Microsoft's definition of feature.

Only up to 9 TB. And thats 10^12. Don't try 2^40.

One fatal flaw with humanity is that it leads to runaway wealth and poverty distribution.
This is not a new problem. Once you can eliminate the humans, come talk to me.
