> You might as well be demanding that every programmer give the government a copy of their source code, in case you die or your company goes bankrupt and people get curious about what you were working on.

You give that example of hyperbole, but I believe that is quite reasonable. I am of the opinion that if you want your code to have copyright protection, you must have a copy of the source code either available to the public or placed in an escrow service to be made public when the copyright expires.

Copyright is an agreement between authors and society. In exchange for limited protection of the work, the work is not hidden from the public, and can therefore be built upon once the work is in public domain. If the author is not allowing the work to eventually enter the public domain, then the author's side of the agreement is not being upheld, and they should not have copyright protection either.
I'm also confused by that statement, especially as I was using msn over xmpp up until that died two years ago or however much it was.

I think maybe the grandparent was saying that you couldn't add msn friends to your contact in gtalk, but you could add gtalk friends to your msn. Or maybe its something to do with emoticons?
VR for flight sims is a bit different than the designer scenarios that to me seem the most interesting use scenarios of the current fad in VR.

An architects experience on hololens:

https://youtu.be/70xDCokzAck

Microsoft promo - but I doubt the architect would like to make a total ass of himself. I work in CAD for construction and while not directly involved in Hololens projects people mostly see this as transformational for their clients. So, there might be actual value here but the market has not yet spoken.

In previous VR surges designers were not so educated in digital and the workflows were not there. VR was a thing itself - now it's more like a one more view into an established process and dataset - and is actually only an incremental change and not a profound one (and is thus likelier to succeed)
Ask HN: If I can Hack it together using Google does that make it useless?
By this I mean, when I am hacking away at an Idea I'm constantly hit by the thought that, "If I can do this by hacking away with google, then why can't someone else? Like say for instance the guys who wrote the tool/code/framework/widget I am basing my work on".

Does this happen to anyone else?
I have a reasonably large project that was started in late 2013 (so only 2.5 years ago) when 2.7 was already long "to be deprecated" but some of the key libraries used were not yet python 3 compatible.

I haven't actually checked, it could probably be ported now - but why would you do that now - everything can change in the next 3 years.

Hi, Author of this here!

The title "Changes sshd port every 30 seconds, using Two Factor Auth to login"

This isn't what the project is about, It was mainly done as a joke for all of the people who say "Changing your port is security by obscurity", and thus the idea came to make a even more insane/silly version of it.

It's using "two factor" to generate the port to connect, not to login, there are loads of ways to authenticate SSH with TOTP tokens, but this is not that.
Similarly, the municipalities of Boston and Cambridge remain separated by the natural border of the Charles River, even if by nothing else at all. Cambridge and Somerville don't even have that much justification for existing as separate municipalities: you can accidentally walk across the municipal border and back again without noticing it in some places.

Cable has a significant difference from oil.

Cable is a network technology with value defined somewhere between Sarnof's, Metcalfe's, or Tilly-Odlyzko's laws. Scale, and dominating local coverage, matter.

Oil is an extractive mineral resource with very low direct costs vs. use value. Absent some form of central contrl, the price has tended to fall far too low. In the aftermath of the East Texas oilfield discovery of 1930 (the biggest on the mainland lower 48), prices fell fist to $0.13/bbl, then to $0.02/bbl. That's barrels, not gallons.

The governors of Texas and Oklahoma called out their state national guards, and the Rangers in Texas, and seized wellheads at gunpoint to cut supply. The quota system imposed, run by the highly innaccurately named Texas Railraod Commission, lasted until 1972. Daniel Yergin's book The Prize covers this in detail.

A similar control program applied to strategic minerals was created after WWII, originally called the Hobard list, and remains in effect as part of the Defense National Stockpile Center.

Raw material and networking economics differ.
The problem with this response is that it's mostly right, but misses enough that it ends up being misguided but for a reason that is unstated.

Similar to the author I worked with HMD systems while in the air force, specifically the integrated HUD avionics F35 helmet system. He is correct about the current lack of accommodation (depth perception) and the vestibular mismatch for movement. Other posters discuss vestibular stimulation, without realizing that such stimulation actually induces physical motion. The biological systems are too tightly connected to just simulate physical movement in the brain without a physical reaction.

What he misses, which is critical is that certain virtual retinal displays can solve the accommodation and multiple depth object focal lengths. This is the major thing that magic leap has going for it, but while it's hard it's not impossible to do in multiple ways. We have our own multi-depth accommodation vrd patent filing.

There is no real solution to the movement problem though... Except to actually work with virtual objects in the real world, AKA augmented reality.

So the actual solution to his problem doesn't lie in VR solutions, it's in AR.

Until we have sufficient BCI that works around vestibular and ocular pathways we aren't going to see the matrix levels of presence in non AR displays.
Unfortunately people have taken this a little too seriously, I wrote this as a joke/PoC of silly "Security by obscurity" methods, and yet people are for some reason viewing this as a serious solution...
please don't insult me.
This is a very bad idea.

If I suspect you're doing this, I can definitely probe 30k ports silently within a second. How many tries do you think I need to break the last two digits?
Of course they were. And I was frustrated (and creeped out) by their "wacky robot dog prancing through the forest getting kicked by the handler" videos.

Evolution seems to tell us certain things about legs. I assume they have reasons for clinging to this approach. But it creates an obvious perception problem because, man, those videos are weird.

Google's got rainbows popping out of their logo meanwhile these guys are punting pets. A culture clash surprises whom exactly?
Entrim 4D (out of Samsung's C-Labs) seems to be a bigger one.
If someone bombs the free port and destroys all works held within, will this result in said rich people eating dirt, or will it just bankrupt the insurance companies?
You're being downvoted because you're hyperfocusing on one dimension of people.

That 25 year old will expend many neurons and lots of that fresh cognitive capability on waste due to inexperience. Have you ever met a practicing 70-year old engineer? That perspective and experience has an outsized impact.

The male vs female upper body strength thing is totally different. For one, it's measurable. Second, it's not a job attribute that is offset by expertise -- a firefighter has to be able to carry an average sized person or a roll of hose. 30 years of hose carrying doesn't make it lighter. Usually, fire departments recognize this by allowing fire fighters to retire starting at the 20 year mark.
>The friendly article notes that only about half of users get sick within a few minutes, although most of the rest do as well within an hour.

Practically no one gets sick from Vive in 1-1 experiences, which is all the parent said. The article says VR won't work, but really he just means artificial vection won't work.

There are also plenty of ways of making vection work by limiting certain things. For example with Vive allowing easy 360 tracking of hand and headset, you can avoid all artificial rotation. Some people only get sick from artificial yaw.

Also there are things like FOV restriction you can do during movement which limits vection. Then you can snap back to full FOV once the artificial movement is done and let the user walk around the room again with full FOV: https://www.youtube.com/watch?v=lKnM5gC-XpY

I would guess the article author is bound by non-competes locked into ancient military contracts and can't get in on the startup action in consumer VR and is just bitter. People are probably asking him what he does at parties, and they say in response, oh I know of Vive and the Rift, and it is getting on his nerves so he is just sort of trolling to lash out.

Flight sims with visible horizons do indeed cause tons of motion sickness in a lot of people though. But that doesn't say anything about VR in general.
If you read the article, you discovered that it was talking about politicians, marketers, scientific fact deniers, scientists, researchers and generally regardless of a person's "roles in society".

It does seem a little silly, the readme does also mention it was written as a joke.

Was looking at ways to decrease logspam from ssh login bots some years ago, port knocking seemed like the most elegant solution. I ended up simply moving ssh away from port 22, the logspam disappeared.

I've used fail2ban in other setups, it also has the advantage of being easy to integrate with other systems such as wordpress, sftp/ftps, nginx, apache.
Thanks! I live in a western country so 2 or 3 of the following are covered. The more people I talk to the more I find that funding is the biggest risk - that and people will not risk their current secure job for a venture that will not be backed by investors without showing strong traction.
Film made everyone sick when it first came out as well.

People will get used to the sensation, and get over it, especially as they grow up with it from childhood.
People get their wires crossed about port knocking because it doesn't add much security when I'm trying to find a way to hack you. It does add something when I'm trying randomly to find you to hack.

They make the valid criticism of the first case while you argue the second and somehow the arguments miss in the middle.

I'm guessing that the future will be AR. Heads up displays that annotate reality, e.g. turn static printed books and magazines into hyperlinked text you can tap and expand like a Kindle. When the glasses or projection devices become sophisticated enough, the possibilities will be endless.

I think you're missing the bigger point that he's trying to make - our sensory systems work in concert to provide a full picture of reality and they're very sensitive and extremely well tuned together through a lifetime of experiences.

Just providing an accurate projection of the visual field to the eye's doesn't solve the problem completely. Visual perception is not a passive mechanism, our eyes 'explore' the visual field through quick movements and readjustments and this process inherently locks together the proprioceptive signals from the ciliary and ocular muscles to the stream of information from the retina. By only providing screens, we can't simulate this process in a natural way and our body will detect it.

Similarly - our vestibular sense is strongly tied to our experiences of our body moving through the world. Just using a blanket stimulation of electrodes on the skin will not recreate these signals in anywhere near a convincing enough manner to fool the brain's perceptual processing.

All of our sensory perceptions are strongly linked together - if just one is perturbed in an unconvincing way (try wearing glasses that aren't prescribed to you for a while), our brain will do our "caveman brain" thing and make us sick.
An interesting anecdote - My friend who absolutely cannot play or even watch someone play an FPS game had no problems with the samsung gear(arguably a device on the lower end). You should give it a try and see how you fair.
Well, I don't agree but that's probably because I don't think "cultural appropriation" is an inherently specious concept, as you seem to.

Whatever else you might think about that letter, I thought the authors made it very explicit that they were not attacking the SignAloud creators' motivation.

> I have yet to encounter a chat network that uses targeted advertising, so you're well off into the realm of conspiracy theories there.

You won't see that because that is not what makes the phone number so useful. Its biggest benefit is being able to correlate all those separate data profiles via one unique key. This makes these profiles more valuable to advertisers. You won't see advertisements in most of these apps (it would drive users to the competition) but they don't have to; they just show them in the browser. They already know it is you thanks to the ubiquitous social media buttons and tracking going on.

This is largely conjecture, sure, but the fact that using your phone number is a requirement rather than an option makes me suspicious.

Sometimes I don't mind if two services know that I am the same person, but I would like to be able to choose for myself. Sometimes I do like to use a throw-away email address and a VPN to use some service, simply because I care about my privacy. Often I don't feel that a service needs to know who I am beyond an alias.
What's truly ironic is that the "Don't be evil" company bought a DoD contract robotics company in the first place. It was obvious all along that robots like the Chetah were designed to push the state-of-the-art in robots towards robot killers.

Heh, I used to own one of these 1000-series machines. In my case it was a unit that had been owned by a company's R&D department, so they'd stripped out a bunch of the "arcade machine" stuff, and all it had when I got it was the (19" rackmount) box with the computer in it, plus the helmet and bumbag -- I didn't have the pod you stand in or the hand-held trigger unit, and the software installation was a bit screwed up. Still, you could play the flight-simulator game. I think the main problems with it as a technology were low resolution and the fact the helmet was stupidly heavy.

As the Kotaku article says, it's basically an Amiga A3000 -- the 19" rackmount box had an A3000 with the lid off screwed to the bottom of it. The A3000 had two custom graphics cards with TI graphics processors, one per eye. Head and glove position sensing were handled by what I think was an off-the-shelf Polhemus tracker board, which sent its output via RS232 to the Amiga serial port. Mounted above the A3000 was the "format board" which was a big custom PCB which did a bunch of miscellaneous work: power supplies, audio amplifiers, joystick calibration circuitry, etc.

(I don't have the thing any more, passed it on to somebody else many years ago, but it was a fun toy to have for a while.)

I'm glad someone is still looking after these machines. I used to read about it in Zzap! 64 magazine [1] and drew Virtuality & W Industries logos on my primary school gear as if it was the Tesla of its time. Especially this press photo made me think Jon Waldern was like a 90s Tony Stark / Elon Musk [2]. I still love the design of their hardware even now, the glossy black & T2-esque typeface & the industrial aesthetic of the cables & metal chequered floor plates. (I suspect I'm the only one.)

We finally got Virtuality in Australia (Perth) a couple of years later, and I spent a ton of time in Dactyl Nightmare at the VR arcade with friends. But the place only had a couple of machines, which meant long queues of watching the TV displays with the current players. I think it cost $10 per 10 minute experience as well. It's really no wonder the place closed down after about a year... but as a kid, I loved it.

Why does one have to exist but not the other? VR and AR solve pretty different things.

You say that like being an Aspie is bad. Of course IQ genes don't as far as we know have bad side effects. It seems Fischerian, and actually uncorrected to ASD.
By that do you mean the trials, safety testing and licensing side of it, or the way drug companies approach new drug development?

I've never quite understood why we can't approach new antibiotics like we have with many enzymes - lab forced evolution. That manages to produce dozens of new ones for food, washing powder and the like, so antibiotic discovery seems like an excellent place to use it.
Yeah, but the semantics there refer to merged by an optimization? What's the point of having incomparable examples?
There are consumer oriented research GVS headsets currently under development, Samsung had one at CES this year. From what've heard it's not hugely accurate, but the general sensation should be enough.
Copyright is a different matter. These historical artifacts won't have any copyright on them in the first place, and are physically secured to prevent people from seeing them. If somebody snuck in and took pictures, there'd be no reason for the owner to have any control over the resulting pictures(although the trespasser could be prosecuted).

With code, "[..]sold, insured or stored[...]" are the three verbs under consideration. Selling and insuring likely require somebody to look at it, so copyright is somewhat relevant(although you can make them sign an NDA). But that "stored" verb would mean that writing code for your personal or company use with no intention to ever show it to the public is also illegal. So you wouldn't just waive some benefits, but would be fined or jailed if you don't file a copy with the government.
The idea of Thethered UAVs isn't new. Problem is probably the danger of high voltage tethers that they use.

I honestly thought this was about Trump for the first few paragraphs, and almost quit reading.

While we've found the the scientific meathod doesn't scale, I suspect that a Watson style application could seriously help one day. This is only compounded this with the "publish or perish" mentality. This encourages falsifying results, but also adds more noise to the pool of journals, decreasing your chance of being called out. I don't think the issue is with liars, but with the system.

What we really need now is Scienceology, (no not the religion) but a division of science that analyzes science. Finding better ways than what we have now.

On its own, absence is a bad argument. But combined with presenting a problem (that people will spontaneously form a government and collect taxes under threat of kneecapping) it is a stronger argument.
Perspective projection is the problem. Make the following experiment yourself:

Stand in front of a tall building/chimney. Now look at the base of the building. Slowly raise your eyes to go from the bottom to the top. You perceive dimensions of the building as the same all the time.

Now do the same on camera. You notice the building changes its dimensions as you raise the view.

This effect will make you feel sick when you have it right next to your eyes. Brain simply does much more for our perception to work.

> The 0.1% can fund a lawsuit because you published a sex tape.

The point of the article is that the .01% can fund a series of unrelated lawsuits because you publish an article unflattering of their industry, political stance, ideology, or just stating that cats or better than dogs.

For the 300 it's a trivial amount of money. Like us spending $1000 to shut down a web site we didn't like. (using them to us as 1,000,000,000 : 10,000,000 = 100,000 : 1,000)

My points are that first, this is both really scary because of how relatively few people are in this position and second, we've gone too far: there's no longer any way to stop these people from essentially doing anything they want to control us. They've become effectively gods who will allow us to live out our insignificant lives only if we don't annoy them.

-- Edit (to continue the metaphor cuz fun). --

Remember, the infraction wasn't posting the video on Gawker. The infraction that pissed of this god was being outed as gay. Essentially, this god was angered by being outed. He opened up a portal to our world via the Hulk Hogan video. His lightning bolts were the series of lawsuits he had lined up.

It's also worth noting that this is a god doing battle with a demi-god. Could you imagine the trivial amount of power (= money) (= free speech) that he would need expended to take out one of us antlike mortals.

If you could shut down breitbart or the drudge report (or your least favorite liberal sites) you wouldn't because you're a benevolent god. But then one day you wake up and find that they've passed judgement on you. Well, they can't pass judgement on a god. So you wave your hand and take them out without so much as making the most minor impact in your existence. "I'll show those mortals how judgement is passed! Talk bad about me, will they." That's the real issue here.
