gwiz665 says...

I've only just now seen the new changes, so I haven't really had time to get an in-depth feel for what I like and/or don't like about it yet. I want to get over the "something is different - this is wrong"-phase before giving feedback, so it's not overly negative.

Just as an aside, I'm glad that the community is being heard on the redesign, so it can be catered to how the site is used rather than what you guys think we do.

All the ghostly sounds that are lost when compressed to mp3

SquidCap says...

A bit misleading. MP3 is stored as frames, uncompressed audio is not. This causes tiny phase differences that when nulled causes the differences to be much larger than what they actually are. Don't get me wrong, the resulting sound resembles what we hear in this clip, just with LOT less transients (beginning of sound, for ex "t" in "the"). If you want a true difference between MP3 and uncompressed, it needs to be resynced each frame. The further the clip advances, the differences grow to be larger and larger as the two streams drift apart more and more.

RMS Titanic: Fascinating Engineering Facts

Ickster says...

Me either. I ended up doing some Wikipedia reading, and it turns out that there was a sort of transitional phase where the combination of reciprocating engines with a cruising turbine wasn't entirely uncommon. I'd always thought it one or the other exclusively.

I also hadn't realized how many ships used turbine-electric setups instead of direct drive. Wiki page.

One quibble with the video--I didn't get all of the ships shown when he was talking about coal dust as the reason for black hulls, but at least a couple were late enough that I'm pretty sure they'd been build as oil-burners (SS Normandie for example).

I had no idea they used a Parsons turbine to drive the center propeller. Fascinating.

Ah, got it. I couldn't find my own photos, but google came to the rescue - here is Lake Colac in its "Colac mudflat" phase a few years ago - http://otway.biz/images/lakecolacdry.jpg

And here's a more normal view after a bit of rain - https://fredodonnellphotography.wordpress.com/2012/10/30/jetties-lake-colac/

The lake's only shallow, so it's prone to drying out completely if there's a drought. It's only happened once in my lifetime that I know of though, although the level does go up and down.

There's a man made lake called Lake Wendouree a few hours north in Ballarat, and around the time that a few years before lake Colac dried up they had to mow it... and started a fire in the dry grass! It was still mud underneath, so it was a bit hard to put the fire out too, they couldn't get the fire trucks onto it

Graphics card woes

Gutspiller says...

Yeah, I've been a fan of CoD, but am slowly losing interest as they are getting worse each year, despite them putting 3 different devs on each new release.

Ghosts was published by Activision, but I know what you mean about the publishers pushing for a certain release whether a game is done or not. Seems like the last few years devs have been trying to skip the quality assurance phase, and it's only hurt them and their brand in my eyes.

I'm glad to hear that at least CoD is selling less these days... I can only hope it's enough to show the publisher to not skip that optimization phase of development, and to make sure their game runs better on all different setups of PCs, and not solely making sure it runs smooth on consoles.

ForgedReality said:

Based on reviews, Ghosts was not only a terrible port but just a terrible game in general. EA tends to push their devs to release things more quickly rather than with higher quality. I wouldn't doubt that at least contributed negatively to your experience.

Crossfire and SLI can be dicey though just because the GPU's have to know how to talk back and forth and stay in sync with each other, which just escalates the probability that something can go wrong either from the game developers' end or from driver support . Single GPUs are plenty powerful these days, so I'm right there with you with the single GPU approach. I've not gone back to multi-GPU since my 4870x2 many years ago (which usually had issues due to ATI constantly breaking the drivers and then having to fix it again every other update).

Prototype Helicopter Crash after Catastrophic Failure

kceaton1 says...

This is one extremely well made machine. I cannot even believe how extremely well this held together, even after the crash (it was practically still in one piece). I find this carbon-fiber/single piece engineering breed of helicopter fascinating. It is far better in a number of fields--and then on top of EVERYTHING to see it go through this absolutely catastrophic situation and remain in one piece (as they said, many helicopters would start breaking apart mid-air due to the absolute savagery of the forces involved and at play here; yet this thing holds together the whole time, even though it is a test design and not even an "improved" or possibly it's "final" design).

I really think that this type of design and make will eventually start to make it's way through the industry. It is just too obvious that the bonuses out-way the negatives to me--then add in the fact that while still in it's testing phase they successfully handled a "worst case" scenario breakdown for a helicopter and then crashed it, then once again showing that the helicopter was VERY good at sending all the forces across the design and holding together (showing that it did a good job during TWO events really)... I really don't know how you couldn't be a bit hyped for this type of design moving forward if you were a helicopter engineer, pilot, mechanic, and especially the manufacturers.

To me, my first thought was, this could end up being the "jeep" of helicopters...

shit the coal lobby says-no really-they said this

oritteropo says...

In terms of the Brisbane G20 summit referenced in this video, very little came out in favour of coal The G20 Leaders Communique came out saying that Gas is an increasingly important energy source, that the G20 reaffirms its committment to phase out inefficient fossil fuel subsidies.

The petition above has 2498 signatures out of its goal of 4000.

The Grauniad saw it like this - http://goo.gl/lnU8mC (well, First Dog on the Moon saw it like that, he also had one on coal powered electicity generation - http://goo.gl/MbNMfO ).

Mr. Abbott is left looking very out of touch and stuck in the past after lobbying to keep climate change out of the leaders communique, and then two days before the summit the U.S. and China came out with a joint announcement promising action on CO2 emissions - http://goo.gl/MvG1I5

So, does anyone know what came out of the G20 regarding coal, good or bad?

Trapping Burning Gasses With a Thin Wire Screen

oritteropo says...

I don't think I want to be the one to test that theory, I'd be worried about what would happen after the initial phase... it is quite true though that the two gases need to be in a certain range of ratios to explode. Since earth has a nitrogen/oxygen atmosphere we normally talk about the gas concentration in air, but in the reverse situation you also need a certain percentage of oxygen like your chem teacher said.

There has been talk of coal mining in an oxygen free environment, with the workers wearing space suits, see this Deseret News article from 1970 for instance - http://goo.gl/PEZKp8

I didn't find any evidence that the idea got past feasibility testing.

oohlalasassoon said:

This reminds me of something that my high school Chemistry teacher told us one day. He told us about how gasses require a certain percentage of oxygen to ignite, so, that if you were to fill up an airtight room with 100% hydrogen, such that no oxygen was present, you could open a door to that room and light a match at the threshold without fear of an explosion. Theoretically the gas in the room would only burn at the door-shaped barrier between the hydrogen and the oxygen on the other side. I remain dubious and I want to see Adam Savage risk his life to bust that myth.

Also, actually related to this video: the guy doing the demonstration,Theodore Gray, has an awesome website if you're into chemistry.

The Pale Blue Dot - THE SAGAN SERIES

Sepacore says...

@enoch

Both @A10anis sentences say roughly the same thing, just poetically phased differently as the 1st focuses on the message, whereas the 2nd on the passing of the message.
Consolidated and rephrased more directly "children should have access to this message/video".

To remove the conflicting poetry and interpret it as intended, re-read it while replacing "brainwashing" with "teaching" and "doctrine" with "message".

A-10 attacks taliban positions in Afghanistan

SquidCap says...

And they are phasing that model out.. A10 is simple and it works but nah, they want something hi-tech to keep the budget staggeringly high. It's like replacing every spoon in your house with robots that don't know what soup is.

What narcolepsy really looks like

kceaton1 says...

I also have narcolepsy, but out of the different "versions" you can find, I think mine may be the easiest to handle (though it may depend on person to person). I do get tired, but strangely I also suffer from extreme chronic headaches, which are powerful enough to keep me awake (bad however, as taking naps are almost always out of the question).

My issues revolve around the fact that when I go to sleep I stay in REM, or phase 2 sleep, almost all night long. I will have very vivid dreams that occur all night long (usually I'll sleep for two hours, get woken up by the dream, rinse and repeat). With this comes the more terrible aspects. I have constant bouts of sleep paralysis every night, and on top of this I suffer from hypnagogic hallucinations like crazy (even when I "think" I'm fully awake).

Very rarely the narcolepsy causes sleeping fits, but it is rare. It may be possible that cataplexy is involved, but I doubt it--it simply happens to rarely (although it does mimic it fairly closely).

Anyway, hypnagogic hallucinations and sleep paralysis are NOT for everyone (as I had a hypnagogic hallucination so strong it felt like someone was yanking me through my bed, sound familiar?). This is where the origins of succubi, demons, angels, and aliens taking you away in the night come from. So, if you do not have a healthy intellect and open mind, you may just end up being, literally, scared of sleeping (unless you are on something akin to Xyrem).

My father has it as well, his symptoms are a little more classical, much like the poster above.

crafting a Patek Philippe 5175R Grandmaster Chime Watch

artician says...

The Gist:

Guy in business suit looking thoughtfully out of window.
(Doubtful anyone who designs fine consumer goods, *actually designs consumer goods*, wears a suit). Maybe its supposed to be you! You avant-garde millionaire, you!

Person sketching watch designs. This is probably semi-close to reality, though they don’t show the hundreds of designs the visual designer creates that are dismissed at whim by the aforementioned, assumed (but inevitable even if not shown) suits.

People fiddling with plastic representations of what one would assume as the model for said watch design. Maybe realistic, though with the caveat that two people are sitting there going over said physical design, in any serious discussion concerning the actual physics of the end product. I can *not* imagine that nearly the entirety of this process today, both visual and mechanical design, are not done digitally.

Okay, there’s some CG. Because CG is the next step, rather than the first, least expensive step in any design process today. Who wants to quickly model everything in a matter of hours when you can fabricate expensive, physical material for iterative testing?

Holy shit, was that guy just looking at a wood cutout? I can’t even think of a shitty, sarcastic/realistic remark about that one. I might have misunderstood that shot.

Alright, now we’re machining shit. You can’t really fake that with a few grand for marketing. That’s the real stuff. (1.5m in)

No, they don’t sand/polish things by hand during the fabrication phase. That’s entirely too inaccurate and subjective to the assembler to leave up to human hands. (But hey: it’s a 2.5 million dollar piece of metal, so lets make those buyers feel good about their money spent).

Oh look: gemstones! (???) That's kingly.

More faux machining that is veritably inferior to quality mechanical assembly.

Oh shit, someone just turned a nob!

3.5 minutes in, and we see some actual hand-polished work that is legitimately viable to perform by hand.

Hey lets sand those nodules off the finished pieces, and micro-inspect those printed markings, because nothing about us says “accuracy” without a fallible human to do it. Also: what are they printing shit on there for? Was it pushing the price to $3mil to engrave the timestamps on the faces? That better be the highest quality electroplated coating, but even then I can't imagine that's superior than a tactile, physical representation.

Now they’re hand-engraving the sculpted ornamentation, but it’s one more point I can gladly give them because those kinds of human touches let you know at least some sort of artisan was involved. I can appreciate that, though realizing what I just said causes me to reflect on the inaccuracies of mass-production, and why we would take one over the other…

More microscopes. (Because if one notch is off, it’s back to the furnace for you!)

Awe shit, payday. A guy in a suit looking confident is walking towards your building!

Finally, the gear assembly. It certainly looks fantastic, photographically speaking. I can’t help but notice that all that detail is lost to hundreds of textural indentations or are due to stylized alternating polish/grinding. However, I’m confident that spending $2.5mil on this product would get me the absolute, most accurate, unnoticeable details (hand-made!) within a micro-millimeter of accuracy. Those indentations are like chrome on a street-racer in the 90’s: the more you have, the greater they perform.

@~8min, I’m pretty sure no one works like that at their desk. That posture would kill you in a month.

They know you can’t spin the head of a watch while it’s on your wrist, right?

Awe! It’s got 5 ringtones! That’s way more than any other watch I’ve even heard of! Except everything that doesn’t cost $2.5mil.


If I can take anything away from this that’s even remotely positive, it’s that at least millionaire shitheads are now being just as suckered as the rest of the consumer base. Let me sell ONE of those watches, and I would have enough money to overtake their business within a year, except for that I don't have the greed, dishonesty, and overall lack of morals that it would take to set up a quality factory, and trick such dickheads into buying (even superior BS) products.

Officer Friendly is NOT your friend

enoch says...

what an odd dynamic here on the sift in regards to lantern.

many here (myself included) have seemed to put the mantle of responsibility squarely on lanterns shoulders,as if he represented ALL police....everywhere.

this is not only patently false,it is very unfair.

BUT....

and @lantern53 this is very important you understand this very crucial,pivotal point:

the outrage you see here playing out on the sift in regards to police abuse of power and authority (oftimes directed AT you) comes directly from a perspective on how we all view HOW a true police officer should behave.

we feel (i dont mean to speak for everyone..but im going to anyways) that those in a position of power and authority have to be held to a much higher standard than the rest of us.

why?

because they are in a position of power and authority!!!!

and to abuse that public trust.
be it by the use of violence or intimidation,is the greatest of all betrayals.

so when we see a cop abusing his powers,in whatever capacity,we become outraged and angered.
justifiably so in my opinion.

i know you like to poke the hornets nest from time to time and it gives you the giggles.
ok..thats fair enough...
but stop defending the indefensible.

as a police officer you should be the first one condemning those cops who have obviously stepped over the line.
i am willing to be that you have done just that in your time on the force.most cops i know do it that way.
police policing themselves in a roundabout way.

i have full confidence you are good at what you do and have built a skin so thick not much really phases you anymore,but stop defending those cops that are NOT good cops...they are a cancer on your institution and they make those of you who ARE good at what you do treated with suspicion and wariness.

so listen to those here who are telling you how they feel about the bad cops.these are not criticizing you in particular,so dont feel you have to defend every bad cop out there.

so just as you do not represent every cop on the planet,dont allow those bad cops define you.

we are counting on you to be better.

13 Misconceptions About Global Warming - Veritasium

Enzoblue says...

^ ^ ^ I agree, but it's getting frustrating. The anti's are religiously adamant and they have no problem finding sources to cite. Local radio show here just said that we're in a cooling phase now and Antarctic ice has actually increased while arctic decreased... I'm worn out.
