Two year ago: Openvpn was fine, but webpages of providers were blocked (not a bad strategy...).
Last year: private Openvpn server worked, but connections dropped after ~1Gbyte was transferred, and well known providers were blocked
This year: openvpn was detected (not sure how!) and private server seems to have ended on some "gray" list, ssh connectionsafter that were very slow (although that could coincide with slow internet); sshing to singapore AWS cloud was fine, but i had the feeling that switching between ports for ssh helped after big data transfers or long conenctions. Connecting by mobile (state telecom) was better than by WLAN.
Blocking seems to happen solely based on target (outside China) IP.
The rationale behind blocking vpns but not ssh is simple: China is not interested in blocking perfectly. They don't care about (or even may like) that you can set up cloud servers which you need for your thing outside China. They dont care about 1% of the population and all foreigners getting unfiltered access to the outside world. As long as they can filter the information for the vast majority. Which implies that the material they mostly care about is video, which means that intentionally slowing ssh still enable you to do your admin work, but you can not copy 1000 youtube videos quickly. Also, for ssh there is no "1-click-vpn" client available......
The relevant question is: could you trust the devices firmware in the first place? The las tfew year put a solid upper bound to my trust in this respect?
The way out would be that i would have to license and register private keys for encryption. This is dificult to enforce since there is no way to judge if you use unregistered private keys without entering your home and looking at your harddrive.
The result would be that criminals would continue to use it, and that normal people would be criminalized.
The average tone on the kernel mailing list is not an incentive to participate to an unbiased observer.
If you care about results, dont drive people away. And yes that applies for the whole OS community. Whenever I consider to take part in an OS project, because i find it interesting, i look at the development process/communication and find the tone, way of discussion, and egocentric behaviour inacceptable.
Do you really think i contribute to a project which barely builds in exactly your environment with hundred of obscure dependencies, and when i try to fix it, getting barfed at over the inacceptable choice of standard tool X (yeah, i know, build processes which work out of the box on all linux distributions are *evil*), which seems to be directly from hell?
Do you really think i participate in a discusssion where three dickheads call my approach "SHIT" because they dont like it, without a proper argument, and often referring to episodes which happened 20 years ago as justification?
Do you really think i invest time into projects where the goals are defined by the means, and not vice versa (see the systemd debate)?
I really think i have better things to do with my life.
Yes. if they told me that t oconnect the fridge you build a new network, i would have declared them mad.
OTOH: I worked in a related topic and we figured that the biggest part of the potential savings could be implemented by a timed switch, and a little thought. It's not like the the time of the peak consumption in a country changes day by day, usually you should think about decades.
(The 80-20 rule also applied here: do the simple measures first, and get the biggest part of the saving)
Honestly, when i bought my 6310i i changed the default ringtone in two days. Not because i disliked it, but because i reached for my phone every 5 minutes in the city.....
People who are scientifically to uneducated to understand things in math which humankind understood 4000years ago and to lazy to even learn in school how long a stone takes to fall down to the ground (which we knew 300 years ago), and who can no predict what the expectation value for winning/losing in roulette is, want to suddenly get in the scientific discussion of the most complicated, dynamical, and coupled systems science ever examined.
Usually this happens as soon as they find the final outcome of the scientific process negative for their income expectation or their views (climate change, evolution, racism etc), even if they have been fine with radar, smarphones, TVs, nuclear bombs/power plants etc. before.
Side remark #1: When i say climate science i dont mean the IPCC (which is political in nature). As a scientist i find it pretty disturbing that they write a report in which the claims of interest groups are packed in without peer review, and declare this to be a result of science.
Side remark #2: There is absolutely no doubt that CO2 in the atmosphere will increase the absorbtion coefficient, and thus has the potential and, assuming that no unpredicted effects compensatign for that appear, likeliness, increase the global solar energy input significatnly. Hoping for such unpredicted effects as excuse for screwing around with this global parameter further is like playing russian roulette with 5 chambers filled and 1 empty.
Side remark #3: Our actions should be long-term (25y-50y) in nature, and they should be based on medium-term observations, per head consumption of ressources/energy and/or emmision of CO2 (compensated for industry production). They should be based on opening additional revenue sources and business fields for companies who delevop good products.
Reminds me when i wanted to text "Sweta" (Short calling name for "Swetlana") on my phone to a colleague of mine and my phone corrected it to "Sweetie".....
And assume that these two things are related, and knowing that Russia has an extreme amount of accidents, i assume that can only mean that the Russians have an extreme amount of sex disorders.
I mean, I would have guessed other things-like alkoholism, bad roads, cars in bad technical state, and cultural deficits in estimating risks, but, ok , i the russian government says that all these accidents are related to sexual disorders, i guess i have to take the extreme perversion troughout russian society for granted......
Yes, and instead of a few well prepared terrrorists you have 100 times more stupid young people who accidentally have a gun in the wrong moment. I think that the number of students killed in average per year in the US by bullied and/or antisocial classmates exceeds 12.
I looked at the paper and i have the feeling that they misuse the term "entangled". At least their definition of the density operator seems dodgy. If they would not say it's entangled i would call it a superposition state of a single particle.
Which, in terms of the density matrix is not so different. But we experimentalists usually require two particles with multiple states to use the word "entanglement".
Moreover, since they are comparing a mixed state, i would find it particularly interesting if there is a difference in the Energy Expectation value for realistic Hamiltonians. (If yes, i would not wonder so much about a mass defect).
* Assume movement between stars, with a speed of your choice. * Caculate Energy and momentum convervation in the capture, and show that moving between stars and "consuming" the star (instead of using a tiny fraction of its energy at the peak output) * Calculate the surface/volume ratio allowable and predict what is the maximum mass of such "intelligent" objects. * Calculate the minimum time for absormbing energy (as a function of the gravity pressure), and thus the minimum mass/density of the object * caclualte if solid parts may exist for your parameter range; otherwise state how you intend to process information. * use the implied timescales to caclulate the number of generations possible since the beginning of the universe * Compare your estimations of time, momentum and energy conservation, maximum size, and min and see if lifeforms sitting close to the stars and consuming them by using the light from the stars are the biggest and most efficent creature to do so.
Reality: IF our species wants a chance at long term survival, we MUST leave this rock. Its not optional, its required.
If our species really survives long enough that leaving earth and settling down becomes the best option for survival, then technologies beyond your wildest dreams will exist.
Our current attempts to travel will seem like the idea to use a cannon to reach the moon seem to us.
The labs i worked in spent less than 200kDollar/Year and researcher. In average 10-15 impact points in publications per year for each lab. For the cost of the ISS or a moon shot you could finance my expriments a hunred thousand times over, so i really would appreciate if the decisions are made carefully.
What i really love to see is automonous systems in orbit, i.e. telescopes. I would thing if you uses the money for the ISS on other things, maybe we would not have to built radiotelecope arrays on earth, but coul put them in space. Instead of rdeaming of a manned mars mission, we should send many probes to other planets and moons.
The scientific achievement of the rovers on mars (and the comet mission!) are significant beyond anything we could have dreamt of.
Fine! I dont need cameras. I dont need a networked Fridge. I dont need a networked lighting setting. I dont need to look up the curve of my heating over the year in the internet.
IMHO the machines should be as dumb as possible. Heating/AC should have a timer. (Oh, wait, it has that already for the last 20 years). The energy savings you can achieve by not starting your heating/AC at the same time but "just before you come home" are not so high.
So yeah. MCUs with 128bytes of ram, no network connection, and a power consumption in the muW-mW range without any OS work for me. If you really are interested in comsumption data, make a fucking SD slot - if i write 1kB every minute for 1 year, a 1GB card is only filled to 50%.

on 4 weather ballon, you can place ~ 8 km of nylon fishing line.
So you can randomly traverse a 100x100x100m volume 80 times.
Not unlikely that you crash the papparazis expensive drone with this approach.

Wrong confessions are a big problem for courts.
so solving the comple problem will be reduced to the not less complex problem of weedign out the spam created by idiots?
Put 4 big helium ballons and place nylon wires between them. Operates 24h a day and is cheap.

I think he got something wrong about the relationship between polititics and journalism, at least in a free society.
Because the opponents of the NRA are not nuts enough to go amok there?
