VladRussian2··on Women in Tech: I can learn more. And so can you
in the context of that given blog it seems that feminism is anti-thetical stereotype to the stereotype of all the bad stuff the blog attributes to "white men"

we have backdoors/trojans in chips. While not in seeds? :)
VladRussian2··on Age-ism, Transhumanism, and Silicon Valley’s Cognitive Dissonance
age-ism is for the "over 40" folks in the Valley except when the next rule applies

transhumanism is for the folks who've made the money, and age doesn't matter for transhumans

and Silicon Valley’s Cognitive Dissonance is how it looks for the folks outside of the Valley to whom the above mentioned distinction blurs away due to the distance (in mental and real space).

HBGary, Palantir and the likes... socially conscious, green, recyclable.

a Vulcan reading this would make a mental note "still not ready, check back again in a couple of hundreds years".

While trying to be a parody, the page basically describes ALEC.

VladRussian2··on Decoding Vibrations From Nearby Keyboards With Mobile Phone Accelerometers [pdf]
sounds like one can be tracked even without GPS, just by integrating accelerometer data and even one fixed point of reference may be not necessary as the pattern of movements can, in many cases, be uniquely aligned with the pattern of streets/etc...
VladRussian2··on [dead]
wow. It isn't even a "third strike" (ie. 2 violent/etc.. and the 3rd any sends you away for long) which is also pretty questionable law, it is just a "third toke". I'm wondering how about "cruel and unusual" here?
VladRussian2··on Lawrence Livermore NIF laser fusion experiment delivers record energy output
with extremely low efficiency of lasers, my bets is on Sandia Z machine.

Not that these guys are in any rush to produce practical reactor as they are also mostly nuke weapons research, yet as a side effect they have been making very interesting and meaningful progress during last 15 years. The machine itself isn't for fusion research, it is for X-ray generation, and it just happens that it generates so much and so efficiently that it seems they couldn't resist and finally started trying mini Teller-Ulam :)

VladRussian2··on Ship crosses Northwest Passage, sails into history
>For it to not constitute piracy, it should happen within 12 miles of their shoreline, their territorial waters.

i somehow don't see how actions of Somali pirates wouldn't be considered as such even if it happened inside the 12 miles zone. Piracy inside or outside of territorial waters is still a piracy.

Compare that to a hypothetical situation - if Somali could gather a presentable navy and start harassing ships outside of the 12 miles zone and a presentable looking spoke-person would communicate some theory why it is a right of Somali people - then we'd have just a legitimate territorial dispute :)

VladRussian2··on Ship crosses Northwest Passage, sails into history
under international law any claim not backed up by a strong enough force is void. At least it has been the case so far :)

>Somalian boarding for inspection and collection of fees (which other countries call piracy)

for it to not constitute piracy it should be performed using guided missile destroyer, not an inflatable rubber boat.

>a change of the weather shouldn't cause such a border to be redrawn.

look at climate changes during last 2-3 thousand years and how whole empires/civilizations got appeared and disappeared as a result.

On the [kind of] positive side [for high-tech industry i mean] Canada will become a big customer for air-, ground-, navy- and submarine drones :)

VladRussian2··on One-electron universe
this is why i drop "of thermodynamics" because that calls for many-particles situation. Referring to "2nd law" i mean the generic "non-decreasing" entropy principle, and i'm wondering about its violations - mainly i believe that there are no violations of it in the physical world (as the known laws of physics seems to obey/describe that principle), and this is what prompted my original question about virtual particles.

I understand that pure statistical interpretation allows for non-negligible chances of the violations. What i'm wondering about is whether strong, non-statistical, interpretation is valid - ie. whether anything looking like a violation is just a non-complete calculation. After all it is pretty fascinating that entropy principle applicable (at least in statistical interpretation) on all scales - from the whole Universe down to quantum systems and for all the physical laws/forces.

VladRussian2··on One-electron universe
sorry, somehow partial text got submitted.

>The glib answer here is that there's really no such thing as the 2nd law when you're talking about a small number of individual fundamental particles. The statement "entropy never decreases" is actually a purely statistical claim, and it only rises to its usual level of essentially unbreakable validity when you're dealing with macroscopic numbers of particles

All the fundamental laws of physics, including the Schrodinger equation, follow the 2nd law or in other words they describe application of 2nd law to the given area of physics, i.e. they express "entropy never decreases" principle in terms of the objects of that physical area.

>"there is less "phase space" available (fewer possible momentum states)"

ie. less entropy :)

>an electron and positron are electrically attracted to each other and will naturally tend to meet up to annihilate

2 particles having negative and positive charges - less entropy than the entropy of 2 resulting neutral particles. Attraction (getting closer - increasing entropy) and annihilation (erasing the charge difference - increasing entropy) are in full compliance with, and i'd say direct manifestation of, the 2nd law :)

> a photon giving rise to a virtual e-/e+ pair that immediately annihilates back into a photon

i'm been wondering about validity of virtual particle trick - while it is preserves charge, etc... doesn't it violates entropy principle of the 2nd law, ie. a pair of e-/e+ seems to have less entropy than the original/resulting photon, thus e-/e+ always happy to produce a photon, while photon would never produce e-/e+ pair without "help".

VladRussian2··on Create an algorithm to distinguish dogs from cats
>Smell and sound

when another dog is inside a car that just stopped at the intersection?

Another issue here is that smell of different dogs is supposed to have at least some variation as well (is this feature variation bigger or smaller than variation in size?), and if one dog is downwind then another is upwind - i.e. while smell obviously plays a major role in dog's sensing of the world we just can't ascribe it all to the smell. In my experience visual recognition plays major part in many cases as well (note: i'm not arguing which dog's sense is strongest, only that there are situations when visual is basically the only one that could have brought the information)

VladRussian2··on Create an algorithm to distinguish dogs from cats
you're talking about features important for human model of cognition. No arguing here - for most of the people, using the features you described (and for AI systems built by humans and using the same features), the cats would look more alike than dogs.

>However, the vast majority of cat breeds retain the same facial features and shape.

i had cats for many years and with time learned to see the difference, and i'm sure that some people like judges from cat shows would see even more distinction.

It is all about model of perception (and we naturally think and talk like our, human, model is the [only] model) and how well it is trained.

>Dogs can vary between 8-80 lbs

btw, it is at least 2-180 lbs for adult dogs :)

VladRussian2··on Create an algorithm to distinguish dogs from cats
Do you have a dog?
VladRussian2··on Create an algorithm to distinguish dogs from cats
>cats look mostly alike

only to people i guess. Reminds me about experiment with chimpanzees having problem to recognize faces (face recognition is a sign of intelligence according to the human thinking about intelligence) ... well, until experimenters stopped showing human faces to the chimpanzees and started to show chimpanzees faces :)

It would be interesting to see whether well-trained AI would "think" that "cats look mostly alike" compare to say dogs as it is only artifact of humans perception and of how our perception propagates into the software what we create.

>if you take them back to the past before TV/Computers, people back then won't recognize them as dogs, because of the looks or size. They would have to hear it back and behave like a dog to classify it as such. if all they had was a picture, they mgiht very well refuse and reject say pugs as dogs.

my dog without using TV or computer (at least to my knowledge as i don't know what he is up to when we are not at home) easily recognizes other dogs of all the different breeds and sizes from the distance like across the street, etc...

VladRussian2··on Measuring heart rate with a smartphone camera
basically a smartphone size polygraph or a software version of Dr. Lightman ("Lie to me"). Heart rate, eyes expansion/contraction, pattern recognition on face muscle twitching, like of lips, eyelids, ... Could something like it speed up, for example, TSA lines at airports? Automated "checkout" lines like in grocery stores - face camera, hand palm on touch pad, "Are you a terrorist with a bomb? Choose Yes or No" (reminds a gun vending machine scene from South Park if i remember correctly :)
VladRussian2··on Chilling legal memo from Obama DOJ justifies assassination of US citizens
well, tax laws make distinction between non-Americans and Americans outside of the US. One can see how following the similar reasoning criminal law (or whatever law is the basis for extrajudicial killings (sorry for the oxymoron)) can make similar distinction.

VladRussian2··on Once Suicidal and Shipped Off, Now Fighting Nevada Over Care
>He was given a bus ticket somewhere and some food. I don't think that falls under kidnapping.

Was he free to leave the bus? No (and physical presence or absence of an officer of the State on the bus isn't necessary and isn't material here - that's is the nature of the Force of the State) Thus we have illegal imprisonment/kidnapping at least until the moment the bus left Nevada.

VladRussian2··on Once Suicidal and Shipped Off, Now Fighting Nevada Over Care
doesn't it sound like an FBI matter - basically kidnapping (as it was against their will - i.e. they didn't give informed consent) and transfer across state lines? One can only wonder there are all the overzealous federal prosecutors when their services are really needed.

>What we haven't learned of, at least yet, is rampant industrial espionage by NSA to steal R&D and a pipeline for dealing with the stolen results.

i wouldn't mind if NSA was doing something really useful like that instead of building total surveilance and instilling fears of it into its own citizenry

VladRussian2··on Venezuela seizes toilet paper factory to avoid shortage
obligatory http://www.imdb.com/title/tt0087747/ - the "USSR toilet paper line" opening clip from it (sorry couldn't find it with original english soundtrek) https://www.youtube.com/watch?v=GR0I3DgWXX8

What i'm genuiely wondering about is how Marx missed the "toilet paper effect" in Das Kapital while he was so true on the money with the rest of the theory.
