Zoox presentation in the NeurIPS Intelligent Transportation Systems workshop was similarly cringeworthy. First half was them going over the numbers of auto fatalities worldwide and how they should be eliminated, followed by very little information on how they would even come close to human level performance on the task.
Specular reflector preserves the etendue of the light rays that fall on it. Diffuse reflector (such as the moon) does not; it becomes a new light source instead, resulting in higher etendue.

In short - perfect reflector preserves etendue, but imperfect does not.
Cheap? Just wait until they make an example out of those two. It definitely won't be a cheap event for them.
Tetris has sold 170 million copies.

Super Mario Bros sold over 40 million copies.

Both of those games are 30 years old. Wii Sports was not even close to being one of the first mainstream games.

The original Pokemon games sold over 30 million copies, inspired a massive worldwide TV show, and that was over 20 years ago.
Nope -- the stipulations of the licensing policy on Internet freedom in Iran are still in effect: https://www.treasury.gov/resource-center/sanctions/Programs/...

See specific of the current application of the rules here: https://www.treasury.gov/resource-center/faqs/Sanctions/Page...

"Specifically, section 560.540 of the ITR authorizes the exportation from the United States or by U.S. persons, wherever located, to persons in Iran of services incident to the exchange of personal communications over the Internet, such as instant messaging, chat and email, social networking, sharing of photos and movies, web browsing, and blogging, provided that such services are publicly available at no cost to the user."
This is really good news considering I already take 10 mg of CBD 4x/day. I don't like the majority of the CBD industry which seems rife with unfounded, dubious claims and sketchy products, so I buy 99.7%+ CBD isolate with mass spec printouts to back it up and mix it with organic high-oleic oil and organic flavoring myself. It's far cheaper per mg and you know what you're getting.

Malaysia seeks $7.5B in reparations from Goldman Sachs
It's sometimes hard for me to articulate to others why I read so much science-fiction, especially to those who see it as just another form of juvenile fantasy. Articles like this serve to illustrate that the writers who are carefully plotting out the future today may end up influencing the future of technology and culture more than they imagined. Clarke, Asimov, PKD, Gibson, they are all accepted as good writers, but I think some day a selection of such writers may be seen as visionaries who not only predicted much of what was to come but significantly influenced the course of that history. Personal computers were widely dismissed in the early days as impractical and unnecessary, yet I suspect it was those engineers who had been exposed to some of the possibilities science fiction writers were imagining for such devices that saw where they might end up. Once the idea of a globally connected network of computers became entrenched in enough people's minds, it was only a matter of time before the problems would be solved. TCP, DNS and HTTP were all important milestones in that path, but we could have converged on another set of protocols if things had been different. Good writers can lay out a vision of the potential in such a system in a way that private business and government usually can't, because they operate on a very different time horizon where they can look past the limitations of what's possible today and imagine what it might become.
I'd only recommend to take out Notes from the underground and replace it with Idiot, which Dostoevsky himself liked the most of all his works. Devils and Gambler are just below these three. Also, Humiliated and insulted allegedly made Nietzsche cry. But that one I haven't read (yet).
As notatoad notes: it's entirely impractical. There's no such thing as anchoring in the depths (3-5000m IIRC) prevailing in the Pacific gyre hosting the 'garbage patch'. This alone would require a revolution in marine engineering. The frankly silly idea was quickly walked back, but it was an early & vivid demonstration of the hapless naiveity underlying the whole enterprise.

It reminds me some of driving trucks into crowds to terrorize. Not sophisticated or expensive but effective.
Thanks, this is what I was missing and what I think is most obscure in the article!
Robert Bly’s Iron John is a phenomenal book on masculinity. What a shame the Mythopoetic Men’s Movement didn’t go anywhere and we instead got the RedPillers.

FWIW, also, this book along with Way of The Superior Man by David Deida, and How to Make Friends and Influence People were staples of the PUA Scene reading list circa 2008.
In the city here, I always see those trucks modified to vacuum debris from parking lots. They begin their "cleaning" thing around 12AM. They seem to just shoot the stuff right up into the air and make a huge mess. Not sure if they are supposed to work that way, or the machinery isn't being maintained, etc.

Some of us use Slack because we have work to do.

How noble in reason! Some of us were banned without justification from our jobs today via the unjustified unilateral action of a private company. In fact, my job is to help companies secure their internal communications. So, talking with people about this was my job. What was yours?
Really needs a TL;DR style summary at the start. Or at least a couple brief examples to show the approach in a concise manner.

While I could spend significant time reading the entire manifesto, I’d appreciate a way to see up front if it’s worthwhile doing so.

The author has rejected similar calls before: https://news.ycombinator.com/item?id=18425581 but I truly think it would be beneficial to a lot of potential readers.
Well, he didn’t even do the engineering so... it’s just entertainment.
Steam seems to solve this fairly well. If you need a runtime it is installed along with the product.
Perfect reflector exists only in theory. But we still put (imperfect) reflective coating on spacecrafts.
When Power Goes to Your Head, It May Shut Out Your Heart (2013)
Maybe somebody was fired and got pissed off. Similar to a sysadm that changes all passwords on his way out of the door
> The target will be in a bath of 499-501nm light at 1/2 the intensity (energy density per unit volume) of the sun, which is far more than half the temperature of the sun. It’ll catch fire after a while.

Unconcentrated sunlight is slightly under 1400 watts per square meter. It's equivalent to a temperature of 122C.

You can concentrate sunlight coming from the sun, because the sun only fills five millionths of the sky. With a simple lens you can focus hundreds of megawatts per square meter onto a surface.

But once you bounce that light off a diffuse surface, whatever concentration you had becomes the new maximum.

In your experiment, bathing something in moonlight would max out at 700 watts per square meter.

700 watts per square meter doesn't set things on fire. It can only heat a blackbody to 60 degrees C.

Even the full brunt of unaltered sunlight can only bring a blackbody up to 122C.

-

Treating the moon as a blackbody or not doesn't actually change the equations. The important property is that it diffuses light. It resets your maximum concentration of light, because light that comes evenly from every direction can't be concentrated.

(I'm ignoring the part about wavelength filtering because it's confusing and would only make your piece of paper heat up less.)
You cannot define "the game" as MVP, make it as good as possible, and then be sad about not making money.

You go there without a game(!) and put different stuff in front of people's faces that they can pay for. Simple things that you can produce in a few hours. A kickstarter page, game_object.jpgs, planning schedules that you move up one year each year, engine demos, and then you look what brings in most cash.

And only if it's "engine demo" that brings in most cash, and only if it seems that the paying customers of that "engine demo" want "more gameplay" then you start building a game. If they pay more for schedules or for kickstarter pages, then you do more of that.

So I would argue SC follows much more closely the MVP+iteration principle than ED, and that IS(!) why it is financially more successful.

All that said I would not fall into the trap of defining "financial success" as only success. Financing the building of a game that is mostly there for people to enjoy a space simulation is also a succss! And in that regard X4 and ED are much more successful than SC will ever be.
You might want to cite your “most certainly” because I’m far from sure that’s true in all jurisdictions.
Actually manipulating higher-degree Bézier curves (or B splines, etc.) is a pain in the butt. In theory you can make any possible shape, but in practice it’s very difficult to get it to do what you want using the standard provided user interface.

> weights of the tangent vectors

Is this a synonym for curvature? In theory you could directly specify the curvature at a knot.

Or do you mean something more explicitly like weights in NURBS? Those could also conceivably be added, but IMO the hit to human intuition / intelligible UIs makes it not worth the trouble.
>Specifically, I feel certain that one can start a fire with sunlight reflected from a room temperature mirror, and don't understand the difference between a mirror and the moon within Munroe's argument.

A mirror does specular reflection and thus conserves the etendue of the sunlight. You're concentrating the image of the sun in the mirror, not light from the mirror itself.

The moon in contrast is mostly a diffuse reflector - it scatters most of the light that falls on it (and absorbs and re-emits most of the rest), so it is effectively a new light source.
Now that we have multiple hypotheses (patriotic motivation and materialistic motivation) we should think about how we could tell which one it was. I can't think of any way that we could ever know the difference.
Rumour is that they were emviromental activists.

I guess it depends on the industry but it is somewhat common for electronic components. There are a lot of failure modes in parts, picking, soldering, and assembly. The economics widely favor doing testing at manufacturing time (versus something like at a distributor or dealing with customer RMA which may come with other externalities like brand damage) because boards can be reworked in the factory and you avoid other waste like packaging, shipping, and tariffs.

Back in the day extremely elaborate and massive bed of nails in circuit test rigs would poke the leads of a through hole circuit board to do continuity testing and basic functions checks. Now a lot of that can be done with JTAG circuitry, a serial bus many ASICs implement and chain together to provide less invasive way to similar tests. Xray, thermal, optical scanners are often used in various parts of the assembly. And of course plenty of humans. Test rig design is a big part of any manufacturing process and may be used to verify overall system function like button presses and connector fidelity.

As a separate but related thought, in VLSI: verification design, for both manufacturing and BIST, can easily eclipse the rest of the design in some ASICs in terms of cost/effort/complexity.

Software engineering is kind of the odd duck in that it is frequently a shoot first ask questions later pursuit in most organizations (funnily, even commonly in places like semiconductor companies that invent and progress new formal methods). There are plenty of decent tools like Lamport's TLA+ that aren't widely used in addition to more familiar aspects of code test.
It's very worrisome how things have been going on in India, more so in the last two decades. Regardless of which party is in power, mass surveillance is increasing, and ways to preserve privacy have been under attack (the government tried to force Blackberry to allow interception of all messages when BBM was a thing; now it wants the same with WhatsApp and other platforms; and then there's the whole biometric based, unchangeable and irrevocable unique ID called Aadhaar...the list is long).

Unfortunately, most politicians here don't understand (or don't care about) the impact of any of these even to protect themselves from attack or suppression by authoritarian and untrustworthy people in power. Most states also have laws that allow them to detain people without a court order or presenting them in a court of law for up to a year, and the police can also make several laws and enforce them.

It's just a matter of time that immigration officials and police will start asking people to reveal their social media passwords, go through their personal and private information, etc.

For all the positives that India as a country has, it has a lot to learn from other countries when it comes to privacy, freedom, freedom of speech, etc.

I believe big technology companies have a role to play in India and around the world to help defeat such dangerous (and often futile) moves by governments.
Right before Christmas... oh boy. I bet the terrorism charges will be thrown at those two. Anyone can come up with similar case from the recent past ?

Why didn't I get any money from my startup?
Unironically this. NPR even has a subdomain for text only (text.npr.org), but only select articles are ported because reasons.

A thorough joke.
You can focus 1/100 of the light onto 1/100 the area. Or 1/1000 of the light onto 1/100 the area.

You can't increase the density of the light. You can't focus all of it onto a smaller area.

Is that clearer?
This looks great. I appreciate the article as an example of how the specifics of an algorithm impacts user experience. Far too often we think of user experience as being independent of the implementation, like it’s just a layer on top.

Perhaps for these two it won't be so cheap, but they just PoC'd a drone DOS rather effectively.

For example, if the control system can be adapted to be driven very remotely (think US military drones -- operator sits in an office building in the US, drone is flying around the middle east) then there's no reason this couldn't be perpetrated by someone very far away, potentially outside of the jurisdiction of the country they're unleashing their drones on. They could go and set up the base stations months in advance of an attack in relatively remote areas, as little drone sleeper cells. When the attack happens, the perpetrators are far away, and much harder to stop.

I expect we'll see more of these, but I hope that this attack made it very clear that there needs to be more effective ways to track and disable rogue drones. I do wonder how they finally found these two (and if they are even the actual perpetrators) but I think they're gonna want to keep those cards close to their chest.

Suppose you are right. The effective temperature of the moon is 100 degrees Celsius. It is a grey-body, so its spectrum is dominated by black-body - e.g. it would be similar to spectrum of black-body with temperature lower than 100 degrees Celsius. So your argument is that the light we see from Moon is same as light we would see from a black body heated to less than 100 degrees C? Try putting a charcoal in boiling water and please report to us if you see it lighted up as white as the moon.
I've been using lesspass for a while, I would highly recommend it. It is extremely simple yet very effective.

I think this was very sophisticated. They planned. They hid. They monitored media and adapted plans. They minimized thier efforts to obtain a result. This was leagues ahead of any recent terror attack. It would be no shock to learn that they had some military, officer, training.
Ask HN: A modern book how to build a scalable web application?
Hi,

I have a close friend who started to learn programming. He want to be a backend web developer. It’s a great book about building scalable websites https://www.amazon.com/Building-Scalable-Web-Sites-Applications/dp/0596102356 but it was written in 2005 and now we have clouds and containers.

So, a question is. Is there a modern version of this book or on this topic? Could you recommend any title?

Thanks a lot for any tips ;-)

Interesting bits...

One piece of equipment believed to have been deployed at the airport is the Israeli-developed Drone Dome system, which can detect drones using radar. It can also jam communications between the drone and its operator, enabling authorities to take control of and land the drone.

In a move known as "buzzing the tower", it emerged the perpetrator had taunted airport staff by circling the drone around the building and flashing its lights

A detailed description of the drone, provided by witnesses, meant experts were able to determine the make and model of the machine, which is only available from a handful of locations in the UK.

Police and military experts were deployed to search for the operators of the drones, which reappeared near the airport every time the authorities tried to reopen the runways.

TLDR; There are no sure fire way to track down offender and police mainly relied on informants and traditional detective work of identifying drone and who might have purchased it.

Better coverage is here:

Sure, my comment was purely informative , I am not a Star Citizen critique because I am not following this game since I am playing single player games. I am curious if you tried the X games from EGOSOFT (for some reason I could not get into them but the latest one looks better) , or if you tried Space Engineers (this one appeals to me because I could create or import Star Trek ships and create my own thing , though I am waiting to be done before I get back into it.
Well, that is the heart of the debate. Folklorists like Satu Apo are pretty convinced these particular tales are literary creations, not compilations of oral tradition.

Perrault's Sleeping Beauty was actually a retelling of this literary fairy tale: https://en.wikipedia.org/wiki/Sun,_Moon,_and_Talia

Not really: NP-hard problems are a set of a decision problems "does a route shorter than x exist?" while in quantum computing, we know an answer exists but the question is obtaining it. E.g. the factors of a number always exist.
I wouldn't much too much trust in what the telegraph says
That's a great ideal, but the technology just isn't there.

With any system that tries to adapt to my preferences, I find myself thinking constantly about how my behaviour will influence it. I'm careful about what I upvote, I try to avoid pausing scrolling on uninteresting things, I even avoid reading articles which I don't want to see more of, even if I find the article itself interesting (remember that users are not necessarily logical - e.g. I don't wait clickbait even though I'm just as drawn as anyone else by the titles).

I would happily trade all of that mental load for a couple of buttons after each item "more like this" or "less like this" and a guarantee that nothing else affected the algorithm. No advance in the last ten years has changed my mind about that, and my hopes aren't high for the next ten doing so either.

I think there's a case to be made that even hard AI wouldn't be sufficient to solve the problem. When my bank manager suggests a product to me, I'm doing the same thing - wondering "why are you suggesting this to me, what's motivating this?". I still want inputs and reasoning exposed, not merely for the answer to be, on reflection, correct.
Really?
