Does viewing this link make one a criminal under the UK's new legislation on viewing material likely to be of help to a terrorist?

Anyway the page has disappeared but can be seen on the Wayback Machine. The page itself seems not to contain any information that would fall under that legislation but perhaps some of the links it contains might.

As it is in the Wayback Machine and that is mirrored I wonder if the mere existence of the mirror would be enough to expose the hosting entity to a risk under the UK legislation.

"viewing material likely to be of help to a terrorist" - seriously?

That would apply to a guide on how to browse the web and use Google, wouldn't it?

noir_lord• 7 years ago

That's why overly broad laws are a terrible idea.

This and it's ilk are basically "because we don't like your face" catch-all's.

Sadly the UK is good at those to whit - The Anti-Social Behaviour Order (defunct but lastesd from 98 to 2015) which made previously criminal behavior a civil matter.

We are a curiously illiberal liberal democracy.

Or a gym training plan, since terrorists don't want to be overweight!

1) No

2) It's not new law. The law is from 2000. You can diff these two for the new bits

original: https://www.legislation.gov.uk/ukpga/2000/11/section/58/enac...

new: https://www.legislation.gov.uk/ukpga/2000/11/section/58

3) Stop reading the shitty fucking register, because it's misleading you.

benj111• 7 years ago

"makes a record of information of a kind likely to be useful to a person committing or preparing an act of terrorism"

Instructions on how to build a cruise missile would seem to fall under that. So do you have a slightly more helpful answer. Whether it is from 2000 or 2019, seems irrelevant.

pjc50• 7 years ago

There have been prosecutions under this law, but they're remarkably difficult to find. The UK press has a weird habit of not reporting actual terrorist convictions in very much detail.

Fun stuff. There is an apocryphal story of an event at the annual Blackrock Amateur Rocketry fly off where the Bureau of Alcohol, Tobacco, and Firearms either confiscated (one version) or denied use of (another variation) a rocket that had been steerable fins and was designed to use orientation with the Sun as a means to keep it going straight up. The story goes that once a rocket can track a heat source and fly based on that track it becomes a "munition" and is no longer just a rocket.

That said, the information that you can make sophisticated weapons with off the shelf parts is not new nor necessarily rare. Everything from guns to armored machine gun platforms, drone bombers, to drone like cruise missiles seem to have not only been built but fielded in recent battles. It's hard to imagine that anyone can keep this sort of information "secret" by hitting individual web sites with cease and desist orders.

Ritsuko_akagi• 7 years ago

a gun is a sophisticated weapon? I though you could make one with a metal pipe, nail and springs; provided you have access to cartridges. could be wrong though.

bronco21016• 7 years ago

Not only is a simple gun, as you describe, able to be readily and easily made but, one can also make a sophisticated gun (AR style) through 3D printing or even using a relatively inexpensive CNC.

ChuckMcM2• 7 years ago

Well you can make a cannon as easily, but the BATF has been aggressive at pursuing people who discuss gun making, the more sophisticated (like 3D printing them) the more aggressive the pursuit. A project for recreating a black powder musket? Not a lot of heat. A project for a repeating launcher that lobs soviet era grenades while pulling the pins on exit, very aggressive pursuit.

mirimir8• 7 years ago

Hey, I did that when I was 13 or 14. There was lots of ammunition lying around in the woods, if you knew where to look. Mostly 7.6 mm, but some 12.7 mm and 20 mm.

kijiki• 7 years ago

1998, though unfortunately the archive didn't get the pictures/videos: https://web.archive.org/web/20100118003800/http://homepage.m...

Last time I looked into this, legally speaking it is payload that matters, not guidance, at least until you try to export. Though there is a general bias in the hobby against doing things that attract negative attention, even if it is, strictly speaking, legal.

There have been other sun-seekers as well.

djsumdog• 7 years ago

Side note, I always found it funny that one of the symbols for the Royal New Zealand Air Force is the British symbol (composed of concentric circles) with a Kiwi in the middle. The symbol for their air force literally has a flightless bird on it!

andromeduck• 7 years ago

But kangaroos and maple leafs can't fly either...

peteretep2• 7 years ago

That’s beautiful irony, although the concentric circles is far from a British-only symbol

samatman3• 7 years ago

The symbol (and indeed, the air force itself) is directly descended from the RAF.

I’m not sure what your point was, but GP’s was quite clear.

Turns out off the shelf GPS modules are good to 50,000m and 500m/s.

Only downside is you're limited to 4g, but that's not the end of the world.

Low update rate, but workaround-able with a IMU. A simple micro, accelerometer, gyro, and you're in business. Pulse jets can get stupid cheap -- there's not much more to them than sheet metal.

Frame is easy enough to fabricate -- Fusion360 will even simulate your aerodynamics for you.

This thing could be built for waaaay less than $5k; Probably buildable for < $1500, depending on what kind of explosives you load into it -- I have no idea how much those are. It's also well within the range of a hobbyist. Any sort of organized group should have no problem, assuming they can round up an electrical engineer and a machinist.

Any sort of organized group should have no problem, assuming they can round up an electrical engineer and a machinist.

Thankfully most competent machinists and electrical engineers can find more profitable things to build.

I've said repeatedly, our best defense against terrorism is the fact that terrorists are dumb.

It's why good, old fashioned, people intensive police work is far more effective than high tech solutions.

danielvf• 7 years ago

I agree that most terrorists are dumb - in fact, I wrote a draft post on how I think it came to be that way:

jonathankoren• 7 years ago

You're right, but I also think about how the Zetas had (have?) a habit of kidnapping engineers to build and maintain their radio network.

esmi• 7 years ago

I’m not so sure.

His objectives state he is looking to build what is basically a custom jet with a 100mi range and 22lb payload. This significantly out performs the custom RC model turbine jets I found online, and their total weight fueled was like 50lb.

one I found, used, was ~$6K.

No turbine -- pulsejet.

I don't know about cruise missiles but ISIS has modified commercial off-the-shelf drones to deliver bombs. 3 French Special Forces soldiers were killed in one such attack during the battle of Mosul.

I always wonder, is it really possible for a free civilization with sufficiently advanced technology to survive and sustain? Due to development of the contemporary industry, many types of technology, previously only available to major corporations and governments, can now be purchased off-the-shelf for personal use.

The very development of personal computing and the Internet is a manifestation of this. In the early 1960s, computers used to be seen as giant, enormous, oppressive machines used by faceless corporations and governments to produce national statistics, design nuclear weapons, or perform top-secret cryptographic communications. On the other hand, our pioneers of personal computing have identified, that once the power of computers is available to everyone, to "we the people", it may become a powerful anti-authoritarian tool, something we've never seen in the human history. This is the original meaning behind the famous 1984 advertisement by Apple.

And we've been following the same path of liberties and decentralization down the road in the next 30 years. Although today, especially since after 2013/2016, computers and the Internet has somewhat restored its "oppressive" public image, Apple and Google becomes the new IBM, etc, but it's clear that the essence of the technology is still largely neutral, and we have many development in the decentralized, pro-freedom world.

The advent of free and open source software has mostly guaranteed that individuals could has the freedom to use the computer for any purpose. The discovery the public-key cryptography can protect personal communication against the most powerful nation-state on Earth, and in principle, allowing the construction of an anonymous communication system, which is believed by many as a mean to eliminate the state, partially or fully.

Recently, the proliferation of dirt-cheap electronics potentially allows a hardware hacker to manufacture semiconductors, electronic equipment, CRISPR-Cas9 gene editing toolkit, handguns, or missiles in his/her backyard. Most hackers see this aspect of technology as a force of liberation. If some people, somehow, eventually managed to create a stateless world in virtual reality, it would be impressive but not surprising.

The question is, what about malicious actors? Many things a hacker would do can be classified as illegal activities, but his/her intend is not malicious, just a different ideology.

But there are truly malicious actors in all civilizations.

The damage that can be done by a malicious actor in a free world, is proportional to the level of (decentralized) technological development. And they can be something more harmful than individuals - rogue nation-state, organized terrorism, etc. WMDs can be created in days, not years.

And you absolutely cannot ban the technology, for example, cryptography, because it's needed for a free society.

So, the eventual outcome is either,

(A) The civilization is destroyed by a few malicious actors.

(B) The civilization becomes a dictatorship, possibly driven by mass surveillance, where most individual liberties are abandoned, we either have 1984, The Matrix, or Black Mirror.

Or a combination of (B) and (C), found in many Science Fictions. Is that the eventually doomsday of a free technological civilization? Do we the technologists still have hopes? For example...

(D) Due to space colonization, any malicious use of technology can only have localized effects, allows many free civilizations to survive?

(E) Due to mind-uploading, nobody bothers to mess with the physical world?

Did I miss something?

Check out The White Plague by Frank Herbert. And Jerry Pournelle wrote a lot of novels about the CoDominium, an alliance between the US & USSR to suppress scientific research due to the instability it could cause.

segfaultbuserr2• 7 years ago

On second thought, I suddenly understand why "the evil government" is so common in science fiction. It's not only about the well-known libertarian-leaning political stance of those authors, but also an extremely useful literary device to check and balance the effect of hi-tech to create a dynamic balance of force in-universe to ensure stability.

In particular, in some stories, the government plays a relatively ambiguous role - still being the oppressor, but also has an important duty of fighting terrorism, so that the world won't just collapse so easily because of a few mad men, and the hackers can keep having their parties.

Coming soon: Cruise Missile As A Service.

Our on-demand global network of 3d printers quickly and reliably fulfills all your strike requests.

Comprehensive plans with a predictable kiloton/strike billing. Bitcoin accepted. Our activities are carbon-compensated to preserve the environment.

/s (I hope)

TeMPOraL3• 7 years ago

And of course, in a true SV fashion, at least initially most of the strike orders will be fulfilled by employees sneaking up to the target with homemade explosives. You have to hustle, fake it 'till you make it & stuffs.

/s (if your's /s).

DarkWiiPlayer• 7 years ago

Remember those "twitch plays X" streams? How about "Twitch fires cruise-missiles" next? Just hook up the twitch chat to your missile API and get that sweet internet fame.

This would make for a great Rick&Morty episode, though :).

atemerev• 7 years ago

I quite understand the motivation behind the project — this is absolutely great. However, open publication of all details can create all sort of problems, including those he described.

If you want to be a weapons designer (and why not?), your best bet is probably working for the government. The second best option is to limit information distribution to other hobbyists / professionals.

solidsnack9000• 7 years ago

Seems like the project was ultimately not completed: http://www.interestingprojects.com/cruisemissile/diary.shtml

bArray• 7 years ago

This project is awesome regardless of it being a weapon. Trying to prevent information from getting out there is ridiculous - if somebody wants to kill lots of people they will find a way irrespective of actions taken to prevent it.

The safe guard here is: (1) there is a reasonable level of engineering competence required, (2) a resource barrier (time and money), (3) building something like this is quite obvious and (4) most people don't want to hurt people.

Given Pu, a gun type nuke is basically banging two rocks together. Given DU, Pu is just hitting it with fast neutrons and chemically separating. Given marginally free hydropower, fast neutrons are a homebrew fusor and a light switch away. DU and hydro turbines are cheap. A hobbyist with patience can build a lowtech fission bomb.

Carfentanil can be manufactured by the billions of lethal doses - or scaled to trillions, with a HELOC.

Virosynthesis isn't a hobbyist endeavor yet but soon will be.

The only reason we aren't all dead is lack of incentive. Of course a sufficiently bad government can change the incentive structure overnight.

triplesec• 7 years ago

This is probably the best book on how the professionals had fun building rockets back in the day. It's a gread read, and full of useful practical chemical engineering advice and cautionary tales. You might find PDFs, but you can also buy it here: https://www.amazon.com/Ignition-Informal-Propellants-Univers...

richardhod• 7 years ago

Some quotes here give insight into the fun and dangers involved. https://www.goodreads.com/work/quotes/663284-ignition-an-inf...

'“It is, of course, extremely toxic, but that’s the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.” '

I think I learned about the book from this blog, or a HN post of it,and it is both fun and expertly informed. http://blogs.sciencemag.org/pipeline/archives/2010/02/23/thi...
