Your first step in reverse engineering aka total mastery of a device should be something a little simpler, like a 2600 or a PDP-8 or if you "demand" something modern, perhaps a very small (pun intended) microcontroller like the pic 10F family. You don't mention any previous experience with reverse engineering so I assume you have none.
Because they scale non-linearily, reverse engineering something simple and something hard doesn't take 200% as long as just reverse engineering something hard, it takes more like 100.1% longer, so the tiny extra investment isn't going to slow down the overall project too much. However the experience you gain figuring out the simpler thing Might dramatically reduce the time taken to figure out the hard thing.
The standard/. car analogy is you probably should start with learning how to change the oil before you try to rebuild the engine.
Its not a hazing thing or making fun of noobs, its just good practical educational advice. Trying something way beyond your level at best results in frustration, at worst in a sorcerers apprentice disaster.
I'd think it would be very hard to fake, since trying to tune the shape/composition of a dummy "key" to adjust one frequency will mess with all the others.
Oh boy please talk to some RF EEs before you roll this idea out. Generations of EEs have written books and created careers on this very topic of wide band antenna/matching networks. Its not trivial, but its not really all that hard either. Some of the math is quite icky, but we have computers now.
it could be some mystic-looking crystal
Yeah, made out of silicon or germanium and doped with some exotic materials in a odd pattern... aka a transistor or IC
Every RF EE since the first wideband transistor circuit has been doing this since the transistor era. If you allow hollow state aka vacuum tubes we have about a century of experience.
Device generates the signature, then it exists in a digital form and can be replicated or spoofed.
From a hacking perspective thats the best news ever
a measure of how the body's tissues oppose a tiny applied alternating current - and learns how a person's body uniquely responds to alternating current of different frequencies
Decades (centuries?) of RF EE work revolves around RF matching network behavior. Essentially its measuring how you'll behave as an antenna or at least a wildly reactive dummy load (aka rf termination). This has the interesting side effect that given nothing other than the physical coupling design inferred visually and some time with the victim and my network analyzer I can whip up a custom little SMD circuit board made completely out of passives that would be electrically indistinguishable from the victim.
Even better, if the RF freqs are low enough I can make a universal circuit board that would do DSP stuff in real time to feed it what it would like to hear.
It looks pretty easy to electronically spoof. Electrically spoofing retina patterns takes all kinds of weird optics, and electrically spoofing finger geometry takes all kinds of woodwork level work but all you'll need for this is "touch the gadget to your homemade bracelet/necklace instead of to your skin".
I would imagine this doesn't work very well. Decades of RF work by handheld radio RF guys (public safety handhelds, ham radio "HTs") shows that the RF characteristics of a human body vary wildly and seemingly randomly within a fairly narrow range. So its pretty easy to make a hand held radio/antenna combination that always matches better than 3:1 SWR but impossible to make on that regularly matches better than 1.5:1 or whatever. This is partially because the body interacts with any nearby field, but also because most quarterwave antenna designs assume the radio and human are part of the groundplane of the antenna. In practice this means you can predict overall antenna system performance within about 6 dB or so, repeatedly, but forget about predicting more accurately than 3 dB or so. The relevance of hand held radio antenna matching to this story is I do not think you can store much more than 2 or 3 bits of "crypto key" data using this tech. I'll go way out on a limb and give them 7 bits of crypto key equivalent, so I could build 128 circuit boards and be more or less guaranteed that everyone reading this could be spoofed with one of the boards. It would be very much like having all passwords limited to 2 digits.
Its creation is an achievement because gliders were previously thought to exist only in regular cellular automata, such as the most famous one, the Game of Life
On wikipedia that would get flagged as weasel words (or the whole article deleted for non-notoriety). Who thinks gliders should only exist in regular automata? If anything my opinion is that modern automata thought was the other way around, expecting them to exist.
Note that gliders are not rare or unusual in automata. Some of the first original researchers thought that only gliders/spaceships that exist lived only in Conways GoL but further research a long time ago showed they're ridiculously commonplace in other rulesets. As seen below. So the tone of this discovery is more accurately described as "much as we suspected, but never bothered to prove, until now" rather than the stereotypical serendipitous discovery tone of "that result looks weird, WTF, who ever would have guessed"
This is separate from the penrose tile thing, which I don't follow. It might, or might not, be the case that a glider in the very specific ruleset of penrose tiles is a hard problem. But in the wide universe of all rulesets, gliders/spaceships and stuff seem very widespread. As a general rule if a ruleset is terminally boring then it definitely does not have gliders, but if its not terminally boring then almost all of them have either chaotic and/or glider-like behavior.
".... I have investigated whether gliders exist in many semitotalistic rules similar to Life, where the behavior of a cell depends only on its own state and the number of live neighbors. The results show that the existence of gliders is commonplace....."
".... We displayed all gliders of Rule 54 including two new glider guns (also extensible)... "
Rule 54 has nothing to do with the famous rule 34. Well I guess there are self replicating patterns in CA rule 54 which could be interpreted as pr0n by another one dimensional cellular automata, I guess.
Whats up with all the sexist names, only chicks can be personal assistants or what?
How bout a manly name, like Kit Carson, to make it all techie we'll call him "KITT"
How bout a manly name, like Hal Linden as seen on "Barney Miller" about 40 years ago and in reruns after the late news ever since... We could call him "HAL" for short.
Its kind of a 5hit or get off the pot thing, like if you're going to be all sexybabes and just rely on objectification of women for your app sales, then just give her a name like "barbie" (duh) or "natalie" (who got married recently, lucky guy) or "Brittany" (who looked a lot hotter before she aged so quickly). I can see the slogans already "instead of just staring at a rack, you can order it (and the attached women) around". Icky creepy for my tastes.
The idea of everyone else knowing I've got an imaginary ditzy babe who I talk to all the time and she never does anything right... Oh isn't this the plot of "I dream of Jeanie"? Or more like "Weird Science?". Imaginary hottie slave is not really a part of my wish fulfillment so I'm not in the target market.
Here, I'll prove it to you that this whole tech sector is way too creepy for breakout success with the "normals". Try to sell alternate voice packs who sound like "Hal" "my grandma" and "grouchy old man" and watch the weirdos line up to exclusively purchase the "I objectify women" hottie app instead.
If Steve Jobs sold an "iNflatable Babe Secretary" as a phone holder/charger/dock/milk dispenser (sorry for clockwork orange reference) it wouldn't be any creepier.
Now don't get me wrong... I love pr0n with the best of them and a little objectification is not all that bad. I just think its cheesy to pretend its all a "productivity enhancer". Don't sell me schmaltz and tell me its classical, don't sell me pr0n and tell me its art, miscategorization is all I'm saying. If you filed all this "PDA chicks" with the "dating sims" I wouldn't blink, thats where they belong.
Hope you enjoyed my rant, if so please mod me the F up?
It never works that well. I've seen the logs/graphs. Dew point skirts the bottom of minimal acceptable in winter (around 40 F, from memory), and skirts the top of maximum acceptable in summer (around 60 F, from memory). I suppose it depends on your center. I'm thinking specifically of a private couple acre financial services DC in the upper midwest, although the telecom data centers I've been in are about the same.
Oh I thought of another one. The problem has nothing to do with temperature. The problem is when the indoor/outdoor/dew points intersect which happens all the time, not just when its cold.
One excruciatingly humid summer day I was hauling around a protocol analyzer worth about as much as my car, and it cold soaked in front of the car air conditioner duct cooling itself to 40 degrees or whatever the AC output is, then it was dripping condensed water as I carried it into the customer premises, an un-airconditioned factory floor. So I'm sitting there doing nothing and explaining to the customer how I have to do nothing, until the test set dries off because its too cold (customer VP looks out window at blue sky 110 degree day). Yes that was an unpleasant meeting.
Let me ask you another question in return. I think I deserve an answer, since I answered yours: Why do you think everybody should know what you think is obvious?
Temp is a bell curve, what we do for a month every year is maybe one day every other year for you.
Cold drive bearings don't want to spin up / SMART fail from drive motor overcurrent. Happens to cooling fans too. Fan can't spin so equipment overheats. I've never knowingly had a voice coil bearing seize up, which is interesting because its probably the lowest power actuator in the system yet probably the highest precision / smallest tolerances.
Living slightly to the east, yet just as cold in winter, the strategy is to leave the gear sealed in the box while you prep the racks and wiring and gather tools. Its really not that complicated. You don't have to wait until the gear reaches room temperature, merely gets above the interior air dew point, which I assure you is very low in the winter.
As Cuba's government found out; you should never underestimate the ability of large numbers of USB sticks gifted by benefactors to facilitate the free flow of restricted information; it just takes a little longer, that's all.
USA can improve information flow, if they recall embargos placed on Cuba. If Cuba is sponsor of terrorism, then its Northern neighbor is not any better.
I don't think you understand the point of the embargo... if 300 million gringos found out they could get better medical care for free 90 miles from Florida it would be an economic catastrophe in the US. The wall is to keep us out, not them in.
spindly creatures that seem to flail about at their own will, banging at the computer keyboard with such frequency and ferocity... to be treated to a maddening drum roll of clicks and clacks.
(Insert nationalism) I would put odds on our average domestic US female facebook addict when opposing a Korean star crafter any day.
I'm not sure what the zerg rush equivalent is called in farmville but even an elite.kr player would have no idea what hit them were they to compete against our ladies.
However this move is just the initial step in an 18 month plan to take the country off the world wide web, and replace it with a state-controlled intranet.
Here's an interesting alternative viewpoint. Everywhere I've worked for 20 years has had airgapped production and IT networks. If not airgap and ridiculously hardened firewall between them. Other than when I worked for Uncle Sam in the early 90s none of these have been "defense" or "secret" networks, just good ole american factories and communications companies, so there's nothing overly secret about this. The interesting alternative viewpoint is that airgapped prod networks are over 20 years old and apparently just now being deployed in Iran. I wonder when the last 20 years of security tech will be deployed to Iran in the future. Like maybe in 2025 they'll switch from telnet to SSH, or in 2030 maybe they'll upgrade from SNMPv1 to SNMPv2. Could they have https intranet servers in a decade or so?
Its interesting to think about. The whole "the future is already here, just not evenly distributed" thing.
With that element of risk removed, I suspect the next attack on Iranian infrastructure probably isn't going to be quite so "restrained" as the last few have been.
Yeah keep thinking that. (Insert Iranian accent:)
"What did the infidels do this time, my centrifuge PLC is Fed again, at least it's not AC/DC playing "Thunderstruck" like last time. Well, lets start up internet explorer and unplug it from halalnet and plug it into the internet so I can google the PLC error message code and download another copy of the.iso install image from the pirate bay of the PLC control software because I lost my copy. (five minutes later) WTF Al Jazzera is reporting a nuke plant in california just melted down, the drainage pumps in New Orleans are running backwards, dogs and cats are living together, and it's all been traced back to Iran, now how did that happen?"
I feel sorry for the Iranian people, who by-and-large, are reasonably normal, but are stuck with a crap theocratic government through little fault of their own.
You'd expect the American people and Iranian people would have common cause, but its always shouted down in idiotic flag waving patriotism (on both sides). Which is too bad. When we sold our soul to the international olympics committee weren't we promised international brotherhood? I want a refund.
Its a design issue. You won't like it because its a PITA. Google for "Peristaltic Array" and apply it to cpu components/microcode instead of the somewhat more popular higher level implementation. Theres about a zillion other high performance computing ideas, mostly unchanged since the 60s and 70s (although continually reimplemented up to current time)
I designed and simulated (in MS basic) a system like this many years ago for fun that operated at KHz speeds (reimplementing in the then unheard of GHz range or THz would be a mere implementation issue). The architecture looks very "streaming" or more like a reconfigurable on the fly FPGA. The main bottleneck for current implementations how do you wedge a multidimensional problem in a fundamentally 2D FPGA and how do you get a FPGA thats big enough to hold fun stuff but small enough that it loads up quick.
Needless to say its a near total decoupling of math and control flow. You might have 10, 100, even 1000 vector items in the stream squirting out one result per cycle, but a control flow loop can only be as fast as light can cross the whole device as you say. Also if you have 1000 items in the pipeline, although this seems obvious, many people don't realize it takes 1000 cycles for the first result to squirt out, which makes it "slow" for anything but repetitive stuff. Although you can play creative games with tossing out data and such, and the ickyness surrounding it it why you won't like it.
said that an unnamed MIT grad student came up with the idea to slingshot the spacecraft around the moon
Now just wait here. The abort plan drawn up in '66 might or might not have been invented by a long haired hippy. Its hard to describe something that obvious as being "invented". The insinuation is the hippy invented it on the fly in '70 during the mission after the O2 tank blew, which is not entirely realistic. By the time the tank blew, the long haired hippy probably got a haircut and a job and a chevvy and maybe even a wife and kid (or two).
Or they may be massively misinterpreting the concept of "inventing". So the tank blows and they're all freaking the F out as you'd imagine, just barely on the sober edge of panic. Visiting hippy who's too stoned to panic says "wow man, just be cool, its early enough in the mission that a AOA is still cool and cosmic, man" plus or minus some weed consumption. Now thats making a valuable observation under severe pressure, not "inventing".
So the secret sauce I need to become a multibillion dollar multinational corporation is spend a lot on advertising, give my projects fabulous color names, hang up a fight club poster... Thats all it takes?
... or are they going to try to make a CPU/GPU core at this speed?
In the long run, maybe. In the short run you aren't going to like it. A very stereotypical microwave LNA MMIC operating around a factor of 100 lower then this device frequency (in other words, cheap and off the shelf) consisting of a couple transistors is biased much like a LED... couple volts, couple dozen mA. Lets call it 4 volts at.040 amps thats 160 milliwatts per device. For rounding purposes lets say a tenth of a watt per transistor. So if you have a roughly quarter million transistor original 386 a 10 GHz discrete 386 made out of microwave transistors would draw about 30 or so KW. Which is quite a lot of power. Of course you don't need low noise small signal performance or great fan in / fan out ratios... Regardless high speed individual devices certainly like their DC power.
The problem with making processors fast is keeping them fed with something to do. CPU tech always seems to lead memory/IO/algorithm design, I can't remember an era when the "memory guys" were waiting on the "processor guys" to catch up. With current tech a 1 THz CPU would merely spend 99.9% of its time in idle waiting for memory... But nothing in the world could run a NOP or an endless loop faster than that device.
I found restful that people aren't on the phone and expect you to fix in the second, or find their account immediately
What culture are you in? Where I work the pitchers consider their chat to be the spoken word of god to obeyed instantly, as if they're texting a 911 center or chat is putting up the bat symbol. Also they always believe you're doing absolutely nothing, nothing at all, other than waiting for them to contact you. And they always believe you're completely alone and not trying to help anyone else. Lets say there's a major incident affecting 50 people. You'll get 25 chat sessions demanding their little whiny ass be immediately helped or they'll cut and paste the chat session complete with timestamps and email it to everyone in your management chain from +1 up to the VP DEMANDING to know why you and your department are not supporting them by replying to their chat session instantly. "Mr VP, would you consider it acceptable to be on the phone and not reply back within 10 seconds? Or 10 seconds of dead air being transmitted?"
My next favorite is the idiots who use it as a dumping tech, like drop some crap on you and log off so you can't reply back that you're 200 miles from the office at a meeting, or logged in from home with no access to that airgap firewalled secure system. Ha ha I dumped on you and you can't help it.
Needless to say our dept nipped this chat idiocy in the bud by disabling the system so we as a dept do NOT use it or support the use of it to contact us.
So nothing is worse than chat if you're a catcher. Of course if you're a pitcher its not so bad.
How about the pulldown notify screen has a list of running apps and you rate them? Making the effort of going to the store and finding the app and then staring it simpler...

I designed and simulated (in MS basic) a system like this many years ago for fun that operated at KHz speeds (reimplementing in the then unheard of GHz range or THz would be a mere implementation issue). The architecture looks very "streaming" or more like a reconfigurable on the fly FPGA. The main bottleneck for current implementations how do you wedge a multidimensional problem in a fundamentally 2D FPGA and how do you get a FPGA thats big enough to hold fun stuff but small enough that it loads up quick.
Needless to say its a near total decoupling of math and control flow. You might have 10, 100, even 1000 vector items in the stream squirting out one result per cycle, but a control flow loop can only be as fast as light can cross the whole device as you say. Also if you have 1000 items in the pipeline, although this seems obvious, many people don't realize it takes 1000 cycles for the first result to squirt out, which makes it "slow" for anything but repetitive stuff. Although you can play creative games with tossing out data and such, and the ickyness surrounding it it why you won't like it.

Now just wait here. The abort plan drawn up in '66 might or might not have been invented by a long haired hippy. Its hard to describe something that obvious as being "invented". The insinuation is the hippy invented it on the fly in '70 during the mission after the O2 tank blew, which is not entirely realistic. By the time the tank blew, the long haired hippy probably got a haircut and a job and a chevvy and maybe even a wife and kid (or two).
Or they may be massively misinterpreting the concept of "inventing". So the tank blows and they're all freaking the F out as you'd imagine, just barely on the sober edge of panic. Visiting hippy who's too stoned to panic says "wow man, just be cool, its early enough in the mission that a AOA is still cool and cosmic, man" plus or minus some weed consumption. Now thats making a valuable observation under severe pressure, not "inventing".
So the secret sauce I need to become a multibillion dollar multinational corporation is spend a lot on advertising, give my projects fabulous color names, hang up a fight club poster... Thats all it takes?
... or are they going to try to make a CPU/GPU core at this speed?
In the long run, maybe. In the short run you aren't going to like it. A very stereotypical microwave LNA MMIC operating around a factor of 100 lower then this device frequency (in other words, cheap and off the shelf) consisting of a couple transistors is biased much like a LED... couple volts, couple dozen mA. Lets call it 4 volts at .040 amps thats 160 milliwatts per device. For rounding purposes lets say a tenth of a watt per transistor. So if you have a roughly quarter million transistor original 386 a 10 GHz discrete 386 made out of microwave transistors would draw about 30 or so KW. Which is quite a lot of power. Of course you don't need low noise small signal performance or great fan in / fan out ratios... Regardless high speed individual devices certainly like their DC power.
The problem with making processors fast is keeping them fed with something to do. CPU tech always seems to lead memory/IO/algorithm design, I can't remember an era when the "memory guys" were waiting on the "processor guys" to catch up. With current tech a 1 THz CPU would merely spend 99.9% of its time in idle waiting for memory... But nothing in the world could run a NOP or an endless loop faster than that device.

Um, yeah, you just go on thinking thats a "future tense" activity. Maybe not intentionally, maybe a lower percentage...
I found restful that people aren't on the phone and expect you to fix in the second, or find their account immediately
What culture are you in? Where I work the pitchers consider their chat to be the spoken word of god to obeyed instantly, as if they're texting a 911 center or chat is putting up the bat symbol. Also they always believe you're doing absolutely nothing, nothing at all, other than waiting for them to contact you. And they always believe you're completely alone and not trying to help anyone else. Lets say there's a major incident affecting 50 people. You'll get 25 chat sessions demanding their little whiny ass be immediately helped or they'll cut and paste the chat session complete with timestamps and email it to everyone in your management chain from +1 up to the VP DEMANDING to know why you and your department are not supporting them by replying to their chat session instantly. "Mr VP, would you consider it acceptable to be on the phone and not reply back within 10 seconds? Or 10 seconds of dead air being transmitted?"
My next favorite is the idiots who use it as a dumping tech, like drop some crap on you and log off so you can't reply back that you're 200 miles from the office at a meeting, or logged in from home with no access to that airgap firewalled secure system. Ha ha I dumped on you and you can't help it.
Needless to say our dept nipped this chat idiocy in the bud by disabling the system so we as a dept do NOT use it or support the use of it to contact us.
So nothing is worse than chat if you're a catcher. Of course if you're a pitcher its not so bad.
How about the pulldown notify screen has a list of running apps and you rate them? Making the effort of going to the store and finding the app and then staring it simpler... Or the screen where you "tap hold" and can re-arrange icons and/or drop them in the trashcan has stars in addition to ye olde trashcan
