In modern planes there is a filter on the warning computer that doesn´t allow to show certain non vital failures between 80 knots (or 100 depending the plane) and V1. For example an engine fire is going to trigger the alarm, but not an engine EGT (exhaust gas temp) over limit. But the list of warnings not shown, and the ones shown but that must be ignored, are different from plane to plane. That´s why this instructor was doing this test, to make them learn that the 777 had a different list and requirements from the previous one. Mind you that after you´ve been in 2 or 3 different planes it´s easy to react automatically but with the previous plane list.

It´s known that pilots are oversensitive to warnings during take off. A rejected take off is a dangerous maneuver that must be avoided if unnecessary, and is trained in each simulator session. This is more important in wide body airliners like the 747, 777, A340 or A380, as their take off weight is so high that a RTO (rejected take off) will blowout some tires (of the main landing gear) due to the stress or the temperature increase inside the tire created by the brakes. Once the plane is stopped, it has to wait isolated at the taxiway because there are temperature plugs at the tires that may blow out, nobody can get close during that time. If the weight is too high they will even burn as the brakes will be white hot. Look at youtube for a certification RTO of a big plane to see it, or some brake energy absorption test at the laboratory, to see how much energy they have to mannage.

In this case(the simulator story) a after cargo door is one of those warnings that you have to ignore as the plane will flight without problems, then you may turn around and make a landing after dumping some fuel(to decrease the weight).

Hope this helps

Edit: some clarification

Below 80 it is possible to RTO without problems as the speed is still low. Once you reach V1 you will NEVER RTO! as this speed is calculated taking in to account the runway length, and in such a manner that if you RTO at V1, the runway remaining once you have stopped is just a couple dozen of meters.
The V1 is so high because that way, when you become airborne, you´ll have a better climb gradient even with an engine fail. All this stuff is calculated with an engine fail, after all it is the most important and probable fail you will encounter (the reverse deployment on take-off is much more severe but thankfully very very rare), and that will affect your climb capability.

Edit 2: added-improved some punctuation.
Do you know any "Feds" yourself? You may be surprised at who is a "fed" or not. Prejudice is definitely not a noble trait.

As was brought up in the other thread, Dark Tangent himself can be considered a Fed, considering that he sits in the Homeland Security Advisory Council, as well as a top officer in ICANN.

Perhaps we'll be seeing Dark Tangent resigning his post as Homeland Security Advisory Council? Or perhaps there is more to "Feds" than you might think.
I'm not sure about CPUs. They don't have direct connections to the outside world. If you want to distrust any hardware, it makes sense to focus on communication peripherals such as network cards, wifi/gsm modems etc.

For example the baseband processors in phones contain a complicated firmware of 16 MB+. This contains many hidden diagnostic modes on various subsystem levels. Baseband processors have been known to be exploited remotely, and as they have direct connection to the main CPU, giving full control over the device, including GPS, camera etc.

There have also been bugs in wired networking hardware in which specially crafted packets resulted in low-level crashes. It was not exploitable in the cases I remember, but I'm sure someone persistent enough and with the right skills may be able to find some.

None of these examples actually "phone home" in the classic sense, but my point is that these peripherals have proprietary firmware that is hardly under public scrutiny, and anything can be hidden in them.
Hi, thanks for your feedback. I've been posting technical Machine Learning issues (my interests) for a while now (a few years), not quite regularly I must say, but no success. I assume I must be doing something wrong here, because others do succeed with similar topics. Moreover, as my professional career evolves so do my interests (business topics), and that's what led me to stick out a little. I'm very eager to learn about the hot topics of a challenging community like HN, and that's what pushed me to ask the question directly.
It's perfectly possible and reasonable to delete all of your data.

It's just hard.

We have to do this with our clients if they shift off our platform and believe me, it's not much fun deleting 20-100Gb datasets from a shared database with over 2000 tables in it on production kit.

But we do it, because we are honest.

Facebook are dishonest. Simple as.
It sounds like you need to do the opposite -- help the bad teammate. Yelling at the person is just going to make them less cooperative. How is it that we've been programmed to yell at these people when that makes it worse? (or have we learned that yelling works and we apply it to everything?)

The Dunning-Kruger effect gets in the way of this. A lot of unskilled people take offense at unsolicited advice, particularly if they're so unskilled as to deem themselves the best player on the team. It doesn't help that the game tracks somewhat superficial stats such as kills and deaths; a score that can run counter to the actual hidden score in the game: gold/experience differential. Like a basketball player who shoots all the time and refuses to pass, bad players will often prioritise individual success in lieu of team success. Then when you try to help them they lash out at you for not having as many kills as them; seemingly ignorant of the different roles on a team.
The "Amen Break" and the Golden Ratio
"Voters said 63 - 25 percent [that X]" means that 63% agreed with X and 25% did not. I guess the other 12% had no opinion.
(a) Real flight simulators are expensive (cost is an order of magnitude less than a real airliner, but still in the millions, and they require skilled operators to put the pilots through their paces),

(b) As I understand it, commercial pilots get paid on the basis of a rather paltry salary, topped up to a much higher rate per flying hour. So there's a strong wage incentive for them to jump in the cockpit of a real plane as fast as possible and get their experience that way rather than spending lots of time training in the simulators.

(c) Modern airliners spend a lot, or even most, of their time on autopilot. Which is not "the plane flies itself" -- it's more like a very complicated cruise control system in a car: you still need to observe and monitor what's going on around you and periodically change some settings governing the vehicle's behaviour. (Just as cruise control won't save you from a bend in the road or an idiot on the other side of the highway crossing the central divider, autopilots need constant supervision.)

But this is not "hand flying". Hand flying mostly comes down to take-off, landing, and brown-pants moments, which is a small fraction of the time a long-haul jet spends in operation. And most commercial airlines are going to take a dim view of pilots who spill the drinks in business class by playing at being a stick-and-rudder hero.
The tools might get written. But they won't be installed on those routers, remote servers you're not getting to install stuff on and all kinds of other places where people who work with networks frequently want to be able to talk protocols from.

It's largely irrelevant to me if there are tools out the wazoo to work with some binary protocol if I'm unable to run that tool everywhere.

And there's a huge range between advocating arbitrarily complex and flexible text protocols vs. binary protocols. You can "easily" do text protocols that are picky about field lengths and that use formats that can be parsed much faster than the more complex protocols.

If your protocol is using a small enough, regular enough grammar, it'd also be fairly trivial to allow a binary serialisation of requests or responses as an option without much extra overhead. E.g. start client connections with a word indicating it wants to "switch on" binary and length prefix any variable length fields instead of relying on an end of field marker, for example. (Or make human clients type out a word to switch to the text serialisation).

But very few protocols are so affected by latency in request/response exchanges that binary vs. text is a huge deal. For HTTP moving to a pure binary protocol might make sense because of how heavily we depend on it. But most protocols are not HTTP.
A similar silly unit is used to measure 'green' energy: "This windmill can power 10.000 households". As if we're too stupid to understand a kWh figure.

Worth adding, because it's not mentioned on the linked page:

When I deleted my account in 2010, there was a one month cooling off period, during which any sign-in would cancel the deletion request.

Perhaps that's sensible to catch malicious/accidental deletions, but I imagine it also makes it hard for Facebook addicts to leave.
Apple designed the language to ease the move of experimental (typically Lisp or Smalltalk) code into production (where it had to run faster, in less memory, etc). Tey wanted a Lisp that ran as fast and as memory efficient as C, so that they could write the OS in Lisp.

That's why they put a lot of thought into the sealing functionality (http://jim.studt.net/dirm/interim-36.html) and into limited types. For example, you can store a 'integer between zero and a hundred or letter of the alphabet or NULL' in a single byte. Expressing that in C is cumbersome, as you would need wrapper functions or macros, would need to remember using them, etc. A sufficiently advanced Dylan compiler could figure out a representation of its own.

Pascal-like syntax was bolted on later when they tried to bring the compiler to the masses. That, in turn, required serious thinking about the macro system.

And no, that didn't work out. There was a prerelease development environment, but they never managed to get this mainstream.
Consider that until people start being told "no, you can't get more IP v4 addresses" or some services are unavailable via IPv4, the incentive to switch to IPv6 is quite low.

We have IPv6 connectivity from our colo provider in one location, and a tunnel to our office, but two years in we're still only testing it for this reason - there's never enough time, and it's not yet urgent enough.
I believe PAPI was operable, so there were working glideslope indicators.
It doesn't, but the fu.gg url should tip of the recipient that he should be careful. Then proper precautions can be taken. Either wait to click until no one is around, or add a ? mark to use the peek version.

The sender/poster could also send the url with "?" added to let the recipient peek slowly.
Under what circumstances are you logging into machines with only telnet available? Presumably you also lack SSH, otherwise you could use a tunnel, so I assume you're physically logging into a bare-bones OS that lacks even basic functionality. Is that really something you do often? And if so, why?

No better group to stand up to them! I don't count myself among the defcon types (my computer wouldn't last 5 minutes on their conference Wifi, I'm sure) but they, if anyone, have the right mindset to challenge the feds, and come out with only minor bruising.
I have to disagree. You are being fooled into thinking that is a stealth fighter or bomber. Its not.

It's a drone which is at mini-scale to the actual aircraft you may be referring to.

Yes. We have stealth bomber looking drones at 1/3 scale to the actual thing.

And to your original point, this is obviously not a first, drones have been taking off and landing from aircraft carriers for years.

Why the washington post is reporting this now is a better question. They are clearly out of the loop.
That's a big drone. I expected a drone to be smaller but that has the size of full brown aircraft.

Agreed. I have been running dedicated servers for years and stayed well away from Amazon due to price calculations, it's such a huge difference in price.

When I worked at start-up the lead dev seemed to be heavily bought into the hype of "cloud" hosting, so he used Engine Yard. The founders got freaked out at the cost for what was negligible traffic. We then moved to Amazon, which equally freaked them out.

If you don't have money to burn, then consider going down the standard hosting route.
Not sure I understand. If Facebook were federated, it would not be reasonable to expect it to delete your data for the practical reasons you mention. Facebook is not federated, so they presumably are able to delete your data. Maybe it's naive to expect them to behave in an honest or considerate manner, but not it's not unreasonable to ask it as far as I can see.

Edit: Of course there's nothing they can do if somebody's screenshotted your post or stored its contents in their brain, but that's not what we're talking about.

Hmm, I'm not sure what you mean by "our platform", but if I post a youtube video, it gets popular, but I get ashamed of it and decide to delete it again, the video will have spread far and wide to other video sites again.

Some for public web pages and the internet archive, for stackoverflow answers/wikipedia entries and SEO rats, and so on.

How is "your platform" going to help me delete my embarrassing drunk student video from the internet's video sites?

The only way "your platform" can do this, is by actively working to block public access to that video in the first place. Then you can have fun (or not) deleting those 20-100Gb datasets. My point is that that means accepting that you're posting stuff to a walled garden.
> I'd rather that my content belongs to everybody than that it belongs to Facebook. But you can't have it both ways.

You can publish your stuff on Facebook or G+ as "public"... I saw some people are doing that, using it as a blogging platform. Then it belongs to everybody but you are also taking advantage of the social elements on those networks.

Actually, I don't think Snowden has made that case. He's asserted it, certainly, but things like the PRISM slides don't back him up.

You might be interested in https://blogs.oracle.com/ksplice/entry/hosting_backdoors_in_... - they show that devices connected to the PCI bus can potentially modify your kernel at boot time, without changing its on-disk signature.
PAPI was operable, however the pilots, both the trainee and instructor didnt look at it until it showed 4 reds. The rule is "4 reds your dead".

That said, a qualified commercial pilot on a clear day doesn't need PAPI or any automation to land an airliner.
Also, if connected via PCI, networking hardware has direct memory access. AFAIK most GSM modems are USB devices, though.

I hope so. I wonder if Defcon was shaping up to be only feds this year, or if there were indications of coming conflict.

I think active rejection by your peers is a reasonable punishment for unconscionable activities in the community. And the reverse should be true for anyone who quits in disgust.

It won't fix the problem completely, but it will have an effect on recruitment and retention. Even if feds in the intelligence industry move to more reasonable IT fields within government, or take contracts as civilian pen testers.
17 hrs since that was reported and the directory is still public.... You should probably work faster, at this time it is safe to assume that all voicemails have been downloaded...

There is this German saying, "Lieber ein Ende mit Schrecken, als Schrecken ohne Ende." which translated means "Rather an end with terror (in the sense of fright, not terrorism), than terror without end.".

> so it can't do any translations on it;

You'd think so, but while it's true we can mostly pretend telnet gives you a raw TCP connection, telnet intercepts some character sequences. It just doesn't interfere much with plain text.

My problem with the hypothetical "http2net" tool is that to this day I still have to deal with systems that doesn't have basic tools like tcpdump, curl or wget. But telnet, nc or some other way of getting a semi-raw tcp connection is pretty much always available.

So I have every expectation that it'd take 30+ years before this "http2net" tool would be available everywhere I'd want it.

What's particularly depressing is the cyclical nature of this.

There are always people pushing for more surveillance and 'security' measures. Always. And every so often the public just lose it and give into them for a few years. It'll happen again before long, just as you say.
No it "belongs" (in your sense of the word) to the platform used to publish it. You loose a significant part of your rights to that content (be it public or private).

The only way to "own" your content is to publish it on your own domain on a host you just pay for storage. You might then link to the content via your (so called) social playground of choice. But you will own the content in a "normal" use of the word.

You can even explicitly state a copyright-info and lay out your terms, that tell everybody that this is your creation, your belonging...

Posting it publicly on any platform that you do not own, will end in you loosing rights to your creation.

You put $100k of equipment in checked luggage, then you probably have some very specific insurance that covers you. If you don't, you are lucky. Most people most of the time do not have anything stolen.

If a baggage handler steals a $3000 camera out of someone's luggage, the airline will totally deny liability.

Like bittired, I also found Frey's Prime Directive not quite right, but for another reason. Thomas Frey criticize our current views regarding the future as being too dark and dangerous and for all that he comes up in the end with "preparing our resolve for struggles unimaginable", which is not (in my book) something put in a brighter note. A message having a little more hope and longing for the better (but not necessarily easier as I agree that life should not be easier), will be more appealing and more in place.

I've tried looking for stuff I posted on craigslist 5 or 6 years ago and nothing was in the wayback machine, only dead links to a few posts.

Apparently the crawls of the site only went a couple/few layers deep, as well as crawls not being conducted daily, and some years had only 2 or 3 crawls for the entire year.

I haven't tried searching my old facebook posts yet though, maybe some sites are more thoroughly catalogued than others.

Perhaps some other entity is storing my old posts, but I doubt that the NSA will allow me to access my own data.

Do you seriously challenge the ones you know? Or is it just small talk?

The feds who pout about stating the obvious, because they're oblivious to their colleagues, seriously need to shape up. I mean, how could you possibly catch robbers and thieves if you can't even look past your own nose?

Are you seriously saying the feelings of random good people who got caught with a bad crowd are worth a police state? There's people who became Neonazis just because they wanted friends, too. Does that mean I don't get to diss Neonazis in general? Nope. Because structures and systems matter more than the people who happen to work in them. The flypaper is the concern here, not the flies sticking to it: they don't get to "take it hostage", and you much less get to take it hostage on their behalf.
Wireshark or similar network sniffer. Any phone-home is going to require using the usual channels to get out of your location to the general internet. Things like TEMPEST require external sniffers; an autonomous agent will have to use what is going to be available, and your modem isn't going to be transferring custom protocols... and if it is, then the ISP's equipment probably wouldn't. And if all three units are, well, things are worse than we could have imagined, but you'd be talking about a conspiracy that would require the silence of an incredible amount of people.
