Seriously. And "small on a chip"? What is that nonsense? Ever heard of chips being put into cases and being fitted with leads? With minimal effort, I found a source that says around 200uA current through a memresistor. That is well within range what you can handle entirely manually on macroscopic scale: http://ieeexplore.ieee.org/doc...
I think this "memresistor" thing is just another instance of people with no clue seeing the philosopher's stone finally being found.
Incidentally, I am not the only one that has noticed that calling memresistors "passive" is bullshit, although that is intuitively clear to anybody with actual experience with electronics :
No. The capacitor is not changed by the charge in it. Hence the capacitor itself does not have state. Given the same situation, it will always behave the same, no matter its history. (This is for an ideal capacitor of course.)
A memresistor is fundamentally different. Depending on its history, it will behave differently in the same situation. Here the device itself is changed, and hence the device has a state.
You are probably confused by the difference between the state of the device and the state it is in. Let me give you a very simple example: A switch can have device-state (device property) of being on or off. It can be in a state (outer situation) where a voltage is applied to it or not. Depending of its own state, that will result in a current flowing or not. One is its properties varying and the other is its reaction of outside stimuli.
A capacitor does not have state. It has a potential charge, but that level is not dependent of its history. The history just somehow has to provide that charge, but it is completely irrelevant how it was provided. Furthermore, a capacitor's charge does not influence its behavior (voltage change on charge-change). That is up to a point, of course. When you reach the breakdown voltage, a capacitor does indeed become an active element for a brief time. As this is outside of normal operating parameters, it is not taken into account when determining its status as "active" or "passive" component.
I do find that you have no clue what you are talking about.
They do not get that their work is absolutely critical for the future of a nation. Or rather those that decide the budget and staffing of education departments do not get that and place 2nd and 3rd rate people there and give them too little budget to do the job well in addition. The underlying problem is that politicians cannot see or plan beyond the next election and bad education has an effect that is delayed by 10 years or so and then only ramps up over time. That bad education continues to have a negative effect for something like 50 years and longer if you add indirect effects (teachers being taught badly as children usually teach badly themselves...) is completely beyond the comprehension of political "leaders".
Indeed. I am still on my z10, because I cannot find any Android phone that even moderately appeals. (No, I will not join the cult of Apple...) Since I do not run any "Apps" on my primary phone, that works fine. For the few Apps I have to use, I use a SIM-less very cheap Moto that is usually off. Hilariously, for that SIM-less phone I use the z10 as wireless access point.
But the situation is really a disgrace. By now I would expect to get well-designed Android hardware (with headphone jack, SD slot, user-replaceable battery, etc.) with long-term update availability (at the very least 5 years). But no such thing is available.
Then maybe we can now finally get devices that have a reasonable long-term availability and regular updates for at least 5 years (better 10) and easily replaceable batteries. You know, the level of quality, lifetime and user-friendliness that can reasonably expected from something as expensive as a smartphone.
Except that a memresistor is not really a passive component as it has state. And there is no "missing" passive component either. I don't know why this obvious BS is being repeated and repeated all over the place. A great success for marketing nonsense, a great loss for actual truth in engineering.
Indeed. But the Neuro-"sciences" are full of cretins that make grand claims and cannot back them up. Remember how start-of-the-art Neuroscience modelling cannot model a C64? (For reference, a C64 is roughly in the complexity of a single neuron to a very small group of neurons.) Most of these people should be stripped of their PhDs for doing gross damage to the credibility of their field.
And claiming one memresistor + one transistor is "close to a neuron"? That is just a direct, shameless lie.
The only thing we can expect (eventually) from memresistors is a significantly better replacement for FLASH cells. That would be nice, but has no connection to the grand visions given in the story.
Nobody knows how the brain works. In fact, the closer we look and the more we know, the more mysterious its workings become. Claiming to bring anything "closer" to its working is a direct lie.
Indeed. Because they are incompetent, stupid and full of themselves. But that will not prevent them from trying. History is full of people that are supposed to be "leaders" doing really stupid things with their power.
We do not have a "math" requirement. We have a "basic numbers and calculations you need in life" requirement. We do not have an "English" requirement either. We have a basic literacy requirement. And so on.
"Computer skills" are a modern supplement to "reading, writing and doing numbers". Most certainly any educated person needs this. CS is a specialist engineering and/or mathematics discipline that is on par with other engineering and mathematical disciplines. Nobody except those specifically interested should do them. It is not only a complete waste of time for the others, it will not at all help them in life and it will decrease the time available for other skills, that may actually be useful to them.
This is about as inane as if since the start of the use of electricity everybody was required to take EE as a mandatory subject. And mandatory courses in all the other tech that the human race uses as well, of course.
Just as other engineering disciplines are not for everyone and are certainly not a requirement to be a productive member of society, CS has absolutely no business being a mandatory subject. The same is even more true for theoretical CS. Might as well force everybody to take Topology or Mechanical engineering.
The problem wit solid scientific results is that they universally say this effect does not exist or that there is an effect to the contrary (people pouring their aggression into a game and being less aggressive as a result), and that does not fit the political narrative (vulgo: "lie") they want to promote. Otherwise it would become very obvious that they are actively and fully knowing do nothing about the problem.
It is blatantly obvious that nobody in power wants to fix this. Otherwise it would have been fixed long ago. Using it to fight political enemies (which is basically spitting on the corpses of those that died) is perfectly fine to them though.

Against eavesdroppers, yes. Against a compromised (or snooping) target website, no. The latter is the main concern here.

They will find something. Extreme greed coupled with stupidity always does the trick. Until the house of cards collapses.

Terminators are made with conventional resistors, and one is enough. Please hand in your geek-card.

If you had half a year, it would be doubtful you could achieve much. Half a day is a complete joke.
They do not produce these. They produce cheap fakes that fail when faced with the first real problem.

Not going to happen as basically all of these people will be completely useless in any CS or IT role.

Pretty much so. Crypto-currencies are built basically on 100% hot air. Well in actual reality they are built on vacuum.
"Magic" is another word for "not describable by science yet". So yes, "magic" is real.
