It seems like the right-bound of the lane (the right red line in the midview camera) was not calculated, so it thinks the joggers were inside a big lane. that'd be my guess as to why they would think the joggers were not "outside" of the lane for the system to breeze by. At 1:23-1:24, there's a person walking their pet and it looks like they were really close, but the camera was able to detect the right boundary.
Why would you think they have 100M users?

"As of today, Cohort is a social graph of over 100M people, and over 700M relationships. We are understanding 10,000 people and their networks a day."

Most all major problems with scale are due to single-process threads. Node.js had it's moment with single-process thread. Blocking will happen even with events but @ scale. He solved his issue with multiple queue-workers + messaging between. This alleviated his blocking, and some people spoke to the fact that node had a cluster workflow which could have also alleviated this issue as well.

Some languages make this workflow more obvious, and some people get stuck in the general way of thinking about problems. I think this is more of an engineering problem and thinking out of the box and ultimately his direction in looking for resources & help within the general community.

I think when you run into problems like these, you need to try to contact the community at large to ask about scaling, and ways scaling is generally done with these types of tasks. Thinking you're the only one who ever experiences trouble scaling is very juvenile and expresses inexperience & ultimately ego. Yes, he solved a problem, but he felt he had to uproot himself in the code already there to do it.

I guess he solved his problem, but he had a quicker path very possibly, he just didn't know it existed.
Agreed. When I make hard-ish science fiction settings that feature better drive technology than the real world, I assume that either:

1. A process can convert normal matter to dark matter and at the same time accelerate that dark matter to some absurd speed -- so you can take a small reaction mass with you and use it very efficiently, but you don't have an ultra-efficient weapon system.

2. A process can push against some background medium of dark matter.

But. If there is dark matter in the vicinity of Earth (and while I agree it's "in the same places as ordinary matter," that's at a macroscopic, galactic level), it's unlikely to be at some convenient rest-y-from-human-perspective frame of reference. Which would suggest that the EM drive would work better facing one direction than others. Which is, I think, not congruent with the experimental evidence in front of us.

We do have more advisors than team. Cohort was founded by me, and I brought three of the best people I know on. I don't know if you've ever been a single founder, but it's really tough to start something, just by yourself.

I've had co-founders in the past, and it's very different doing it yourself. Before the team was properly formed, I asked some friends for help. Some of it was product related, some of it was business and fundraising related. And some was just moral support.

I don't think there's a hard and fast rule to the ratio of advisors to team. Every startup is different, every product is different and every team is different.

As to our value prop and brand strategy, I admit, there's a lot that's not obvious from what's essentially a holding page. -- we're still pre launch, and in private beta, which I mentioned in opening paragraphs of the post.

They will. I made nearly $10k buying up used (and new) ones on eBay and other places and sending them back. I've gotten paid for everything so far.

I also learned about the recall around June, around two months before it started hitting the media, which gave me an advantage. Although my most recent purchase was within the last month, there's still a small opportunity.

Also someone else seems to have cornered the eBay market, items that go on sale now tend to be bought relatively quickly (looking at sold items) before I see them. I probably could have done better by setting up instant alerts and sniping auctions, but I'm pretty happy with what I did get for the level of effort.
It's only exciting if it violates the conservation of momentum. If it doesn't, it's not useful as a space thuster or a flying car, and whatever is causing the miniscule force is just some leaky edge case that's difficult to measure.

It's boring if it doesn't violate momentum conservation.
this article includes a grey body that the force is acting upon.

the difference with the EM drive's method of propulsion is, that while the article you posted describes a force reacting upon an external, "grey body," as is acceptable with the copenhagen interpretation of quantum mechanics, the EM drive force exhibits a characteristic betrayed by a theoretical pilot wave, which indicates a non-copenhagen interpretation of quantum mechanics, but rather a bohmann version of quantum mechanics, in which the force can act upon itself.

They Thought They Were Free – But Then It Was Too Late
> US does not have a democracy

Nope, it's a democratic constitutional republic, and people would do well to remember that is the correct term for our enshrined form of government (though it has veered from it largely).
A surveillance state is the beginning of totalitarianism and no amount of euphemisms can hide that.

Its beginning to look more and more like the general discourse about democracy and human rights was posturing to to see off the threat from Soviet Union and once it dissipated double speak and euphemisms quickly took over. Populations are being trained to accept surveillance as inevitable and shift even more power to the state.

Its impossible for a democracy to exist without privacy. Its impossible for free thought and exchange of ideas with surveillance. The chilling effect and paranoia quickly take over and this is not rocket science given our collective history and our understanding of power.

At the moment the press is more interested in being part of the inner circle and there is little interest in activism from the general population so there is zero threat to power structures from internal sources.

But these are fluid and when activism and a free press is needed to effect accountability and change, societies that embrace surveillance will quickly find themselves impotent and helpless.
The tone you set by using the term "bogus", is IMHO, inappropriate at this point. There's been at least 4 separate groups who've all reported similar results. This latest one has been peer reviewed, presuming it's not a crapshoot journal there aren't any glaring issues (granted that's not saying much given the state of peer review). Nonetheless it's more likely that an unknown systemic experimental error is causing groups to report these kind of results, but not bogus as in the case of a truly bogus "discovery" cold fushion.

> 1. It violates Conservation of Momentum. If the phenomena is real, a large number of basic Physics principles would need to be discarded.

According to our current understanding of the system yes, however, it's also plausible that this works via in a non-trivial interaction of general relativity and quantum mechanics. Which is still a very open question, and may not actually be violating conservation of momentum. To state it more correctly, it appears the em drive violates conservation of momentum by all means we currently understand. Given the minuscule amount of thrust it's plausible there could be a unknown quantum effect. One group tested the drive in vacuum which makes it certainly more interesting if there is an actual novel physics interaction.

> 2. It was designed based on certain principles. Those principles have been shown to be wrong. But it works anyway because reasons?

That's a non-sequitur. If there weren't several repeated experiments showing similar results it might be a reasonable caution. However, many of the best scientific discoveries arose in similar mis-comprehensions.

> 3. The results of each experiment are suspiciously close to the limits of measurement.

This is the most problematic portion of the experiments. It's only an order of magnitude smaller thrust per kW than more conventional drives. However, this article at a cursory reading was designed to try various configurations of thrust to check for potential systematic experimental errors in measurement. At this point asking more serious questions would be required rather than a "this doesn't fit into my preconceptions". E.g. explain how the particular experimental design in question could be flawed, in particular, what conditions could cause the null thrust test to not remove systemic measurement.

In short, scientific skepticism doesn't mean incredulity.
> There no "white nationalist" appointee

In fact there are, including Steve Bannon. There also are religiously prejudiced appointees, such as Michael Flynn and Jeff Sessions. IIRC, that's 3 of the 4 appointees announced so far.

I've used Vi and Emacs 25 years ago - I used to give courses in Vi and I used to write LISP macros for Emacs as a developer support job for some time. Why anyone still uses them is beyond me, I don't see how they make you more efficient than modern IDE's like Visual Studio or Jetbrains et al, but to each their own.

Performance wasn't the aim of this presentation so it wasn't what I was focussed on. But it's instructive to play around with functions to see what's generated under the covers. For adding two numbers together, for example, it can boil down to just a few x86 instructions. Since it compiles down to IL/IR there is a lot of common optimisations from the LLVM/Clang tool chains that are inherited for free. I would expect to see the performance improve over time too.

> the test really needed to be performed inside of a vaccuum

If I'm not mistaken they did, and the thrust was almost the same than the one in air. No perfect vacuum here, but still.

"Vacuum conditions are provided by two roughing pumps and two high-speed turbopumps, and all vacuum tests are performed at or below 8×10^−6 torr"

"The vacuum test data collected show a consistent performance of 1.2±0.1 mN/kW, which is very close to the average impulsive performance measured in air (also 1.2 mN/kW)"
Like many posters here, my first exposure to Octave was from taking the Andrew Ng class on Machine Learning. For myself, I have to say that I was pretty impressed with Octave. It does a lot of what you can do with R, but I find the syntax more accessible. I get the feeling that there aren't quite as many packages/libraries available for Octave as there are for R, though. Still, I find myself using Octave from time to time, when I need to do some quick calculations or whatever. I even bought a Matlab book, intending to invest a little more effort into learning this ecosystem.

Glad to see Octave development is ongoing. It'll be fun to check out 4.2.0 and see what it has to offer.

You're right! Many people rightly consider this very relevant to the lives of individuals. This is something that should always be considered.

Yet, the issue remains - if you tell someone that they are an enfranchised member of an in-group and their lived experience seems to contradict that, two things are likely to happen. First, they will tend to favor their lived experience over your carefully considered claims. Second, they will tend to discount and disregard anything further you might say, as you have damaged your credibility by invalidating their lived experiences.

So, please, consider the possibility that what one expects to be meaningful to a person's life and what that person considers meaningful to a person's life may differ in potentially significant ways.
Nice! Next time I'll have to think of that first.
Unless the point of forcing a physical signature is to terrorize that group as much as to collect names.

For example, lynchings were not intended as genocide but to keep blacks in fear as much as being a source of psychological indulgence for the murders.
The reason we have surveillance is because people either want it, aren't that bothered about it or are powerless to stop it. I think it's largely the former. The arguments against stuff like "if you've nothing to hide" are abstract whereas "you can prevent terrorism by talking people's communications" is an easy to understand truism. It's got nothing to do with democracy but about whether we are at peace. In more peaceful times people can contemplate philosophical matters but when people are fearful that they're going to get shot or blown up by a mad superstitious idiot the downsides of the authorities having access to your Twitter direct messages or browser history are always going to take second place
Actually just removed that stuff and seems to be faster, there is a qrtun_async.py script now with no seq/ack. That being said, my concern was that if creating/displaying the qr code was much faster than detecting/decoding, and a lot of packets were coming in at once, you could maybe display multiple packets/qrcodes before the other side was able to decode the first one. That would result in drops of course which should be re transmitted though, so I guess its okay.

I encourage anyone to read it, even laypeople. It's a great read if you want to think about science itself as opposed to just thinking about the "latest development in $SCIENCE". (Where $SCIENCE could be Physics, Biology, Medicine, ...)

There are a few bits in there that may be hard for the layperson to understand, but I think the overall point is amazingly well made.

I am a physicist, and you are not misunderstanding anything. ESSW defeated a strawman mis-generalization of PWT.
The principles are still the same; some of the APIs that are called have been renamed or had argument types changed but the SIL is mainly unchanged.
He did, yeah. If it works as described, then you'd expect it to break conservation of energy along with conservation of momentum.

That's another good reason to think it doesn't work.

> Humans are generally intelligent. This claim is often considered so obvious as to be hardly worth stating explicitly; but it underlies nearly all discussions of AGI.

I wonder though. Should that really be the goal? This seems like another instance of people's propensity to think of themselves as the pinnacle of something. In this case that something is intelligence.

Here's something that jumped into my mind:

- Samsung recently recalled their flagship phone because of battery problems (http://www.samsung.com/us/note7recall/)

- Intel recently recalled all their Basis Peak smart watches because they might overheat (https://www.mybasis.com/safety/)

The Samsung thing, especially, must have worried Apple's engineers (their marketing and sales departments probably was ecstatic) I expect they will have bought dozens of these phones, attempting to figure out what went wrong.

Could Apple have made a last-minute change to the batteries because they do not want this to happen to them?

You don't need to read or understand (most of) your source code because it is 90% libraries. Mathematics is built based on understanding all the concepts behind a subject, and it's written to express to another human clear rigorous thought.

You cannot just black box everything away and choose to ignore it the way programmers do with source code and libraries.

The metric for success with a program is "does the machine run it properly". The metric for success with a piece of mathematics is "do people who've done some reading in my field understand my new result". You can cheat in one but not in the other.

FWIW, most other Americans support you and share your shock and outrage. Clinton won a majority, remember, despite being targeted by domestic and foreign security agencies, as well as by the Murdoch/Fox empire and the rest of the right-wing demonization machine. Obama is very popular. (EDIT: That's not meant to be partisan; it's just clear data that many people oppose religious hatred - many Republicans do too.)

I hope people get organized now. I hope bad things don't happen, but only by being organized can people act to protect their rights. As a simple example, look at the NRA.
AWS spot instances are a fraction of the price, like 20-30%. In my experience, building the same processing cluster from AWS costs half as much as Google Cloud.

Yes, you move in ellipses; but you spend a lot of time far away and very little time close to the sun. I'm not sure that the average power is any higher than you would have for a circular orbit at the same energy...

EDIT: Ok, let's think through the calculus here. Kepler's 2nd law says that the area swept by the line between a planet and the Sun is constant, i.e., r^2 dθ/dt = 2 π a b / P where a and b are the semi-major and semi-minor axes and P is the orbital period. Thus dt / r^2 = P dθ / (2 π a b); and the former is the instantaneous power absorbed. Integrating over an orbit, we get E = P / (a b); or the average power absorbed is proportional to 1 / (a b).

Since the energy of an orbit is determined solely by the semi-major axis a, this means the power absorbed for any given orbital energy is maximized for b ≪ a; so you're right, that highly eccentric orbits are a better way to acquire energy for the purpose of orbital escape. (Subject of course to practical considerations of energy storage -- you'll absorb the most power at exactly the time you don't want to be changing your momentum.)
Let me clarify. Jeff Sessions and Steve Bannon are capital R Racists. And now they are in positions of power. People are scared because these people are threatening. If you aren't scared, maybe you should talk to the people who are now living in fear rather than staying in your bubble of privilige. This isn't meant to shame you or put you down for being in a position of privilige, but instead encourage you to start looking at things more intersectionality.

Quick example, Mike Pence has come forward in favor of conversion therapy, a violent electroshock regiment combined with mental abuse to "convert" gay youth to being straight. It has an 800% increase in suicides among "outpatients." If you are straight, this might not scare you. But, if you don't have that privilege and identify as lgbtq+, you don't have as much as a choice but to be terrified that this man is one heartbeat from the presidency and has been promised by the president to have a large amount of influence in the administration.
