Friends and colleagues are right to be surprised. If the official story is true two people with a couple of drones outclassed the entire British security establishment for a couple of days.

It's not that drones hadn't been considered a threat, or that there weren't similar events in the past. Threat assessment studies were done because similar events did happen in the past - although not on this scale.

But there seems to have been absolutely no contingency planning, and no clear demarcation of responsibility between the police, the military, the civil aviation authority, and the rest of the government.

The reality is that a lot of infrastructure of all kinds is ridiculously exposed and vulnerable. But the government hands out corporate welfare to trophy projects like a pointless aircraft carrier while making almost no preparations for even the most obvious and predictable technological threats.
I recon for ~$300 in parts your "typical hardware hacker" could build a rig that would focus 600W of microwave energy into a parabolic dish with reasonably tight beam. That shouldn't really affect anything but the drone.

If I was building a drone to do sabotage, I'd build a comms link around modulated NIR lasers targeted with mirrors rotated by microsteppers.
The X was always the [maximum] speed you could read a drive, not a fake number. Drives went up to 56x by spinning the disc over twenty times faster than a CD player. (With the outer edge being 2.5 times faster than the inner edge.)

The 72x drive had especially interesting tech, using 7 beams so that it only had to spin 5-10 times faster. It also had a significantly better minimum speed of about 44x.

Presumably the arithmetician will answer that its factorization is the empty set. That's what sympy says, for example.

>>> sympy.factorint(6)
{2: 1, 3: 1}
>>> sympy.factorint(1)
{}

This definition is also sensible because it also preserves uniqueness in both directions. The empty set is the only prime factorization of 1, and 1 is the only natural number whose prime factorization is the empty set. (Wikipedia has a footnote that "Using the empty product rule one need not exclude the number 1 [from the fundamental theorem of arithmetic], and the theorem can be stated as: every positive integer has unique prime factorization.")

The fundamental theorem doesn't have to state that the prime factorization is nonempty.

It's true that some mathematicians have defined 1 as a prime number and there's nothing logically inconsistent about doing so, but it makes most theorems and formulas in number theory more complex and so this definition has fallen out of favor.

Edit: I think the Wikipedia article on the empty product gives some quite nice examples of the benefits of a closely related concept. https://en.wikipedia.org/wiki/Empty_product

I've seen a lot of suggestions floating around on jamming the signal. But that assumes that there is an active operator and not a drone that has been told to go between a pre set list of coordinates. Most high end should support gps navigation so I assuming that you have enough money and don't need to ever recover a drone after it's out of battery you can probably increase your chances of not getting caught.
I remember one of those huge DDOS attacks a few years ago, where the online speculation of who the perpetrator was centered mostly on Russia, the Mossad, or a guy with a botnet on 4Chan who claimed it was him.

Since then we're living in the future, as far as I'm concerned.

Hello Ralph.

It looks great but you should add some basic usage howto. It is obvious that you know how to use it, you created it, but other people do not.

The first time I used it it was very frustrating because I only created circle handlers, and said: This is sh*t!! Then I close the window and looked back at the sample image and saw square pointers, so I said: There must be some key that creates square pointers. After trying again I discover it creates square handlers by default.

This is the typical engineer mindset, after having spent years doing something they consider obvious what it is not.

So you are making a point that replacing kids with imported people is better?

Having babies with (20-40% chances of them turning into liability) vs importing high skilled individuals with negligible chances of turning into liability.

Obviously, latter one looks better.

But minorities (immigrants) usually collude and rise to top in a nation with strong property rights and legal system.

Then locals are like, hey, this country doesn't even belong to them and they are taking all jobs.

This destroys social cohesion and increase group exclusion where you feel safe only with your own tribe. Covert descrimination increases.

Is that the primary motivation for Brexit? You can see how much uncertainty it has caused already.

This might impact mental health and productivity.

This all has a cost too. So, you can't say immigration is better than having kids based on a rate of turning into liability citizen.

The Future of Violence [0] explores this further. Its TLDR is something like: technology enables distributed offensive capabilities leading to many-to-many threats. Technology also creates distributed vulnerabilities by increasing attack surface. Finally, technology also enables distributed defensive capabilities.

Looking through comments. There is still lots misunderstanding. So let's get deeper into the topic. In particular - how stuff gets heated by light and what light "temperature" is.

Thermodynamics arguments are always good but you really need to understand that most of them describe closed systems under equilibrium. Real world is messier and if your understanding of thermodynamics is shaky its easy to get to wrong conclusions. Black and grey body discussion is in same realm, so we will avoid it here.

Let's consider piece of wood and try to see what it takes to combust it. We need two things - oxygen and high enough temperature. We are keeping this piece of wood in air, so we have oxygen. The temperature is how fast particles that compose piece of wood are moving. The wood consists of molecules, which are in turn consist of atoms. You can imagine a molecule is a bunch of atoms connected with each other by springs (the springs are created by electromagnetic forces when atoms lend and borrow electrons). The higher the temperature - the larger oscillations of these springs. When the temperature is high enough some of these springs can break and combine with oxygen to release energy - combustion.

Suppose light strikes some piece of wood. What happens? Photons hit molecules and they can interact with an electron or proton - they exchange momentum (and energy), which means that one of the atoms in a molecule gets a bump - springs would start oscillating harder.

Note, low energy photons cannot swing springs a lot. We need photons of high energy to swing spring to high temperature (ok - this part is too oversimplified, I can extend on this if there are questions). The energy of photons depends on their waivelength - the shorter waivelength - the more energetic photons. So we need photons with energy that could break molecular bonds (springs) to be able to heat up to combustion temperature. Visible light definitely has photons of such energy.

So we start sending light down our piece of wood, it starts heating up. But it sits in air and probably fixed by some supporting stand. This piece of wood starts exchanging heat with surrounding materials. To be able to overcome this we need to send lots of photons on this piece of wood. How do we do this? We use lens to collect the photons from broader area and send it down to the wood. Note that it doesn't matter where photons came from, were they scattered or produced by sun, what temperature of scattering surface was, not even what temperature of sun was. All what is matter - can we collect enough high energy photons. So we would need to calculate what is energy flux of visible light photons at the surface earth and see if we could come up with a lens to focus these photons on piece of wood to create sufficient intensity.

We know that we can see Moon in visible light, so it does sends bunch of energetic photons to us. All these photon are coming from moon direction (so we don't care that moon scatters them in other directions as well). So the task is to find what is the energy flux of these photons at earth surface and what size of lens we would need to get sufficient intensity.

Reading the comments I found something I don't understand.
What is the difference between
1.black body photons and
2.laser photons
An object will heat only up to the original temperature of the black body source in the first case, but to an arbitrary high temperature in the laser case...
Then you jam GPS

I see the thermodynamic principle at work, here, but I don't really understand how it's operating at a mechanistic level. Is it possible to demonstrate that assertion optically?

Black body photons are coming at random times. Laser photons are coherent, so are timed. Think of swing - if you try to push it randomly you'll get it swing as far as hardest push. But if you push periodically, you can swing it very far with small pushes.
The experience is indistinguishable (apart from maybe some better sound) from my first play through when it came out on PC.
Project the data, not the model. You need to do it anyway and has the side benefit of making overfitting more difficult. Protecting the model is impossible anyway since most advancements terms to be trying lots of publicly known techniques and discovering that a particular combination works best for your data. Once one knows which techniques those are these nothing stopping a competent engineer from reimplementing them at another company.
Take in mind the whole evaluation was from company perspective. What those services are solving is company employees slacking passwords around, sending those via emails and using generic passwords like 'CompanyName123' or 'CompanyName!!!'.

Yesterday night I browsed some groups on Facebook, left some non-useful groups and sent requests to about 5-6 new groups.

Also, no offensive posts or anything. Woke up today and my account has been disabled. And they want a govt. id to "re-check if I violated their TOS." Thanks, Zuckerberg, but NO.

I am missing on a ton of valuable information as some of the groups were pretty amazing. But I'm willing to bet that I'm going to be a saner person and save a ton of time.
What I was talking about is, if the guy just left the country with all the ideas in his head and went back to China there would be no case. But because there is evidence showing he had access to some ideas that he was not supposed to have access to they have a case against him.

Hello from Gatwick airport. Arrived Wednesday evening. About to board my third scheduled flight. I hope it doesn't get cancelled again!

As an American, the British response to this seems very restrained. If this incident happened in the USA, I would have expected tight, armed security everywhere in the airport. Gatwick just seems like business as usual.

Um, public antisemitism was pretty common everywhere in the west pre WW 2. It became a socially unacceptable position in polite circles only after the Nazi genocide.

Racism was a mainstream position back then. For example, US black population got full rights only in the 60's.

The horror of nazis was not that they were some deranged mob of gangsters that only german subconscious could put up with. The horror of nazis was that they could have happened anywhere. They are a historys dark mirror showing to all societies a very bad example of what could be.

I see it very differently, the lesson of Chinese System is that everyone will only work for this own interest. Especially the Chinese. And will be precisely why we have democracy in the first place.

Sanctions and embargos are getting out of hand. Blanket, rather than targeted individual sanctions/actions, truly only harm the people of a country that have little to no say in what their government or country does.

As seen here, sanctions turn companies that provide services into poor customer service scenarios through forced compliance for what reason ultimately? All that does is make it harder to track since we now live in a surveillance society. What a waste of time and energy. We are living in an age of the abuse of economic sanctions, that ultimately harm the wrong people and make companies/products look bad.

There are a lot of support and maintenance positions available to junior developers, with a huge rotation because once they've learnt enough they want to build stuff.

COBOL might be a proven, old, technology... which means maintenance is important. New stuff must be build with a lot of legacy in mind, and you'll inherit legacy mistakes that worked and cannot be fixed unless you overhaul a huge amount of code.

That's not even sexy enough for senior, gray-haired developers; but helps pay the bills.
Aircraft do not rely on GPS precisely because it’s so easy to jam. It’s only a convenience.
GPS disruption is NOTAM'd or scheduled with Ofcom[1] from time-to-time, although not usually at the airport itself. Given that Gatwick was shut at the time, it wouldn't have affected the aircraft since they weren't able to go anywhere.

Steve Jobs' conversation with Terry Gross [audio] (1996)
This is a cool topic, but the examples - FB feed, Netflix, etc. - don't really apply. Those systems aren't trying to maximize user control, they are trying to sustain engagement while giving as much control back to the platform as possible. I'd like to see more work on ML driven UI that is specifically trying to enable user -driven intent.
The internet has allowed him and his ilk a bigger voice, platforms to more efficiently spread their ideology and organize.

In the past, neonazis and fascists had to lay low and work in the shadows. But the internet has a hell of a lot of shadows, and they're all accessible from everywhere. They are also getting better at hiding their true intent behind "identity" and "heritage" and other "soft" forms of their ideologies.

That is precisely why fascism is now a real actual threat to millions of people, and the reason why we must never let down our guard, we have to root them out and expose them for what they are.
I'm up to page 9 on your thesis, and have already learned many things. Your "empirical testing of fairness" section is great.

From your thesis:
> Intuitively, curvature is the position of the steering wheel when driving a car along the curve. Therefore, G2 continuity is equivalent to the lack of jerks of the steering wheel

I particularly like this analogy because I've worked simulating NPC cars in computer games and I found lack of G2 continuity of 3 Beziers annoying - the jerk of the steering wheel clearly put a sudden change of cornering forces through the suspension simulation which looked very unnatural.
Author here, hope you enjoy reading this.

More charitably, this is the way all research prototypes work in any field.

Production vector illustration packages hire a team of people who spend man-years of effort canvassing customers, collecting bug reports, adding features and affordances and refining the user interface, writing documentation, and so on. Someone making a research prototype where the UI per se was built in a few weeks is not going to have the same feature richness, level of polish, or clarity of outward-facing documentation.

Give it some time.
>They admit the mistake was theirs and they take responsibility for it. They say sorry. They explain what they're going to do to fix the situation. They say they're going to learn from this and not have similar mistakes in the future. Pretty solid.

This is true from a narrative/plot standpoint and it's good that you mention it, Morrowind's plot was great. But I was talking more from a gameplay/immersion standpoint. It is true that it's ambiguous whether you are a Chosen One or not, but the thing is that in Morrowind you don't have much choice other than following the main quest because there is not much else to do (OK, advancing in the guilds, but the progression is a joke compared to Daggerfall, a small bunch of quests and you are the head honcho). In Daggerfall you can just live your life as one more person in a large, complex world. I know players who have been playing for years without even touching the main quest because the open-world nature of the game is enough to keep them engaged.

Probably "Chosen One" was not the best choice of words. It's more that in Morrowind, the world revolves around you, it's just a device to tell you a story. To take a particular example (among many), in (unmodded) Morrowind, any town or city is a totally unrealistically-sized town with a bunch of houses and a few mostly static NPCs, which spend 24 hours in the same place and are designed to have dialogs useful for you. On the other hand, enter Daggerfall. A town can have hundreds of houses, with hundreds of NPCs that roam the streets and act according to their daily schedules (quite rudimentarily implemented, but still). You can talk to any NPC on the street but just as in real life, they are strangers and don't give a damn about you because you're just another person on the street; so you can ask them for rumors and directions and if you are polite and they are in good mood you can get some information, but not much more. So you really feel that the world doesn't revolve around you. You are so insignificant that if you go to a city at night, the city walls are closed so you can't even enter unless you climb!
Thanks.
So the laser is really special; because it is coherent it can be absorbed and transformed into heat without limit.
