Re: Mpemba

Yes, and every time I see that mentioned, the part that I immediately get reminded of is this one:

"In 2016, Burridge and Linden defined the criterion as the time to reach 0 °C (32 °F), carried out experiments and reviewed published work to date.[1] They noted that the large difference originally claimed had not been replicated, and that studies showing a small effect could be influenced by variations in the positioning of thermometers. They say " We conclude, somewhat sadly, that there is no evidence to support meaningful observations of the Mpemba effect"."

Re: A lot of self righteous types in today

Now that you mention it - I prefer to avoid shopping from work, so no Amazon, yes. My personal mail I can access any time through my smartphone, but if I use the laptop, it's a webmail interface, and the browser is always set to permanently incognito browsing; I just need to close it. Social media I just flat out don't do. To be fair though, there IS some personal information on that laptop, considering Dropbox keeps a local copy on everything that ever tries to sync with it. Then again, all of it is encrypted with EncFS, which I manually start and enter the password into whenever needed - soooo... given the chance I'd prefer to wipe that cache and de-auth the sync client but ultimately I don't really care who looks at that gibberish, either from work or from the cloud.

DropBear
Facepalm

I think politicians are much like managers in that apparently their job is not having any clue about how whatever they're managing works, but having a clue about how to herd human beings instead. And what is the single fundamental tenet of dealing with people? "Never take no for an answer", based on the observation that the surest way to get results is to assure the full involvement of your lab rat by forcing his interest to coincide with yours - ie. denying him the option to simply refuse what you ask. It turns out this approach more often than not produces results that are a workable compromise (for you the pragmatic tyrant) even when your original request is indeed a physical impossibility. It's all inconsequential - your minion, quivering in terror at the consequences of failing, will come up with something close enough.

Now, these days going medieval on your minions is somewhat frowned upon (to the great regret of the powers-that-be, no doubt), but the principle remains unchanged, which should go a long way towards helping us understand why they act as seemingly wilfully thick and stubborn as they do; it's not that they don't understand there's a fundamental problem with their request, but rather that us saying "no" just means they haven't put enough of the right kind of pressure on us. Coercion always gets results of one kind or another. No result just mean not enough coercion.

From the point of view of a techie thinking in absolutes, an imperfectly watertight, backdoored encryption is a useless thing not worth wasting any further brain cycles on. From their point of view, as long as they get their coveted back door, the rest of us getting left potentially naked in the cold is just a risk they're willing to take, even if they have to outright outlaw all "unlicensed" hard encryption to get there. I don't understand why we seem to think they'd finally "get it" if only we'd explain it all to them once again, clearly enough. Does anyone here seriously see these folks just going "oh, if it's not possible then of course just forget about the whole thing" at some point...? They DO GET IT just fine. As far as they're concerned, we're the ones failing to get it that there's no way out of this room until they get something approximating what they wanted...

Smart burglar alarms: Look who just tossed their hat into the ring ... It's, er, Ring

I don't get all these burglar alarms with "subscriptions" at all. I mean I do get the lure of a "revenue stream" form the vendor's point of view I just don't see why anyone would want to keep paying. Around here you either have a completely stand-alone system that simply howls when triggered (with as much video archiving as your suitably concealed $50 Chinesium DVR's hard disk manages to hold) or if you're really posh, you're paying a subscription to a monitoring centre with actual goons who actually turn up on your actual doorstep a mere few dozens of minutes after any alarm. But $10 just to cloud something something... seriously, WTF?!?

Six weeks later, drone biz DJI deploys control app 'flight mode'

Re: Military helicopter & drone collision over Staten Island, US (Sept 21, 2017)

"But drone pilot would have been aware of the military chopper as they are not quiet or discreet, and could easily have dropped his altitude until the heli passed over. Probably lacking brain."

Not so sure about that at all. We have a medical chopper flying over the city fairly often at fairly low altitude coming in for the landing at the hospital (to be honest, I never saw them fly anywhere at any sensible height, even further away, as if they are perpetually hypermiling or something - the sports aircraft that operate out of the nearby sports airfield are flying incomparably higher, even when nobody is jumping out of them).

My point being, the chopper passes literally in a few seconds at that altitude. If I were flying with FPV goggles as a fairly high-flying quad is likely to, by the time I look around and manage to locate the direction the chopper I just heard is coming from, I'm pretty sure it will have already hit me if we're on a collision course. As for dropping, they may have been doing just that - who knows what height that quad was at when the pilot heard the chopper...

Forget the 'simulated universe', say boffins, no simulator could hit the required scale

DropBear

"If we are in a simulation then it is generally taken to imply something must be running the simulation. That leads to recursion - as at each higher level something must be running that particular show."

I don't see how that follows at all. That would be true only if we were to posit that existence is only possible in a simulation - where indeed someone must be running a higher level one then for each level - but I don't see why we'd need to go that way. Why would it not be possible for an un-simulated form of existence to simulate another?!?

Re: "To model just a few hundred electrons needs a computer bigger than the universe"

I'm finding it remarkably bold to attempt to infer any conclusions about our universe's simulated nature from any findings regarding complexity considering that IF we are indeed in a simulation we have not the faintest idea about a) what kind of hardware does the simulation / what exactly a unit of it can simulate (one would expect a very different performance from an ALU and an FPGA implementing the same complex logic after all), b) how mind-bogglingly large it might be compared even to the vastness of our own universe and c) how much of unobserved complexity it does simulate down to its most accurate level and how much of it gets fudged by ingenious shortcuts and workarounds when we're not looking at it and finally d) how much it redirects intractable complexity from the space into the time domain - ie. how much it slows down (not something that we would be able to detect as long as the rest of the simulation is kept in sync with the slow bits) whenever it needs to recurse deep into some detail (nobody said we're running at a stable 100FPS in "outside world" terms - we might be a slow and unsteady as fuck scientific simulation...)

Let us not forget for instance that any detail of interest of a fractal image down to arbitrary resolution CAN be calculated on-demand never bothering with calculating "all" (for whatever arbitrary limits we care about) the image at the same resolution, working from a very much uncomplicated formula. FFS, we don't even have any idea how many dimensions the outsiders might have at their disposal to expand their mainframe into - it's not like all simulations we run are in full 3D!

So yeah, I'm fully prepared to believe those guys that were we trying to simulate ourselves, especially in a naive brute-force fashion, the ramping complexity would prevent it really quickish-like; what I'm much less prepared to believe is that they know what they talk about when they say "impossible" (or more specifically, that they don't need to rely on a massive heap of embarrassingly arbitrary assumptions to say that).

US yanks staff from Cuban embassy over sonic death ray fears

DropBear

May not be in any way related, but our "insulating glass" office windows (combined with the room acoustics I assume) are annoyingly effective in converting many car's idling engine sound, whenever they decide to wait outside, into the vibration equivalent of standing right next to a Diesel locomotive minus (most of) the actual sound. I mean you _can_ still hear it as deep muffled vibration but you mostly feel it and it definitely is _highly_ unpleasant. Open the window - hear just a normal car idling; close the window - instant brain-vacuuming "whobobobobob" at ten thousand decibels. I wonder if something similar might be happening over there completely accidentally...

Dyson to build electric car that doesn't suck

DropBear

Re: You miserablists

"Interesting thought experiment for all: Would you be proud to work at Dyson? I bloody would."

To be perfectly honest, past typical hearsay I don't factually know enough about them to base a serious job application on - but if they are indeed like Apple, I certainly wouldn't be willing to work for them for any wage (yes, really). And by "like Apple" I mean "successful mainly via being good at talking easily razzle-dazzled suckers out of their money as opposed to actually delivering tech worth the prices they ask". People who actually have a clue about technology typically don't forgive people who do that sort of thing, regardless of how rich they manage to get or how much the real world seems to validate them financially.

And sure, Isambard Kingdom Brunel may well have been a consummate businessman but coincidentally he was also a remarkably good engineer, and that's why he gets a pass and respect from most of us all around. Had he been just another "never mind the substance, feel the hype" P.T. Barnum, rest assured we'd ridicule him day in and day out too - kinda how Edison is a bit shunned in certain circles these days thanks to his business acumen being arguably a bigger part of his success than his actual tech prowess. Whether I'm right or wrong (which I may well be), that's the "illustrious" company I see Dyson in, and in my book, that only gets them contempt and scathing ridicule. And if there ever was a properly mean, vindictive bastard - I'm it...

Re: You miserablists

"Exactly how successful does an engineer have to be in Britain before you lot will be positive about them?"

You must be new here. Yes, I know full well you aren't but that only makes the question more perplexing. IT'S WHAT WE DO. What's the point of pointing out stuff that is just fine and dandy? Everyone else out there is lining up to do that (even when it's not true, which is most of the time), they don't need us for that. Rather when stuff is plainly bollocks instead there should be someone to point that out too, and we happen to love doing just that. But let it not be said I'm not addressing your point - as a matter of fact I don't see much bickering around here regarding Elon's rocket landings so hey, I propose a new El Reg unit: One Musk as the threshold of engineering achievement at which bickering reaches zero. You're welcome.

Vibrating walls shafted servers at a time the SUN couldn't shine

DropBear

Can't speak for the OP, but as far as I know, due to elevator designers not being total numpties, elevators typically get counter-balanced with half of their maximum load, so either full load or zero load are both worst cases vs. the typical half-load which might barely exercise the motor. Not to say that was the case - maybe any elevator motion triggered the problem but they only used it at night for freight...

You better explain yourself, mister: DARPA's mission to make an accountable AI

DropBear

Methinks DARPA brass is confusing Hollywood reality with real-world reality. I don't see this happening until human-equivalent AI arrives so it can articulate its own reasoning (assuming it's able to at all), and even then I don't see it avoiding the notorious "gut feeling" shit we humans love to pull. Stuff like "why did you fire at target #1" ("because I was ordered to guard and it had a heat signature") or "why target #1 not target #2" ("because it was the closer one") is easy - but good luck with "why did you think heat blob #1 looked like a tank?". The goal itself is praiseworthy, as long as one remains aware it's in the same category as "we strive to visit other galaxies".

iOS apps can read metadata revealing users' location histories

DropBear

"How would it know to do that, especially if the app accesses the photos as files rather than as images?"

That's just it - no app should access files other than its own unless it's generally meant to handle files or receives access to open certain files directly. An app that just needs access to photos should just receive a string of small image thumbnails (then the selected image in full resolution, if any) from the OS unless it also gets granted access to metadata. To be honest, it's already _hella annoying_ that any app is simply supposed to be able to access _everything_ on the SD...
