Launching Small Rockets to Space from Jets

rich_magnet says...

100 lbs to LEO for $1M: that's $10k/lb. Cheaper than the space shuttle, but a fair bit more than what the private launch folks (will eventually) launch for. Also the video doesn't show de-orbit or passivization of the 2nd stage, meaning this is a potential source of a lot of new space junk. Furthermore, since this is Darpa/military, it strikes me as a cover story for further weaponization of space.

Blasting a mountain top to build world's 'biggest' telescope

newtboy says...

I think it normally depends on the mountain. As I see it, most people have an issue with destroying mountains for things like mining because 1) they disagree with the reasoning for it, 2)it's in places where people can see the damage, and more importantly 3) those 'mountains' are often much lower altitude and are decent habitats for critters with significant water runoff that's contaminated by 'mountain top removal'. When you're talking 9-10K feet up, beyond the tree line, there's far less habitat being destroyed (granted, something likely lives there that's now dead or displaced). That means it's not 0 damage done, but far less damage to what most people consider important. Very few people care about damaging the rock itself, mostly Shinto and Buddhists I would guess. Personally I find this a good trade off of damage vs possible gain, but of course I don't live there.
I'm wondering how this is better than the VLTA http://www.eso.org/public/teles-instr/vlt/
I expected there to be no more giant telescopes made now that they know how to combine smaller ones to simulate large ones. I wonder why they went this way on this project?

Wouldn't we normally be against blowing up mountain tops?

I can't deny that I too am OK with this as it furthers our understanding of the universe by building this. I just can't help but to feel hypocritical.

One Of The Best Arguments For Deleting Facebook

Warmth- says...

NSA knows what's best for you.

I mean, surely their filtering algorithms have already analyzed a more accurate profile of you, than what your psychiatrist ever could? What with all the years of records of your internet searches, emails and videosift comments..

Seriously though, about this nice video, if you have a popular smartphone, no matter how you trust that fruit, droid or window logo, there's seriously no real guarantees that your activities are not recorded in whichever way, whenever. Any data on 'customers' is precious to these companies, or the NSA for that matter.

To be a bit cynical, I'd say that most people don't mind, they can't perceive anything strongly negative to come out of any of these privacy breaches. After all, so far the system has kept them relatively safe from the other ones, the evil ones.

To be even more cynical I'd say this hip guy, 10k likes on FB and all, seems to be quite smoothly riding the next generation's "My mom uses FB" disdain to .. I don't know? Maybe try to gain respect among this, certainly most sought after viewer demography, the younger generation, about to become consumers?

It could even be that he makes money on ads on YT views? But certainly Youtube, or their parent company, would never breach anyone's privacy, or make questionable sudden changes to their TOCs? Say, they wouldn't use the Chrome browser's or the Android OS's capabilities to use a connected mic to sift through recorded data?

Well, in any case, I've got to appreciate anyone who makes these matters more public and talked about, what ever their motives might be.

On another topic, as a loyal user of Google's mostly brilliant services, and mobile operating system, I was quite surprised to realize that I could see where I (or my phone) had been about, through their service here: https://maps.google.com/locationhistory

Luckily the feature can be turned off from the same site. I mean I'm sure it's off now, because I can't see any data there anymore..

Everything You Need To Know About Digital Audio Signals

CreamK says...

It's been tested and the "best" audiophiles can't hear differences between 14bit and 16bit, nor can they hear differences between 44.khz and ANYTHING higher. In some tests they could use12bit sound with 36khz sampling frequency... The differences they hear are inside their head. Thus the description of improved sound is always "air", "brilliance", "organic" etc.. Don't be fooled by their fancy gear, most of it is for nothing. Cables: i am always willing to bet my months salary on doubleblind tests, 10 000€/m against a coat hanger, no audible differences.. It's all about confirmation bias, you think there's a change and suddenly you hear it.

About MP3s vs PCM:
Here we have audible differences. But. Put on high enough energy, ie turn your amp high enough, suddenly double blind studies can't find which is which. But it can be audible, mp3 is lossy format and even 320kbps can be heard. Not with all material, it's about in the limits of human hearing. Some might hear high end loss, if you're in your twenties. Once you hit 40, everything above 17khz is gone, forever. You will never hear 20k again. And to really notice the difference, you need good gear. Your laptop earphone output most likely won't even output anything past 18khz well and it's dynamic range can be represented with 8bit depth.. It can be just horrible. Fix that with usb box, around 80€: you can take that box anywhere on planet to the most "hifiest" guy out there and he can't hear the difference between his 10000€ A/D converter.. In fact, 5€ A/D converter can produce the same output as 3000€ one... That's not why i said buy a external.. It's more to do with RF and other shielding, protection against the noises a computer makes than A/D conversion quality. Note, i'm talking about audible differences, you can find faults with measuring equipment and 95% of the gear price is about "just to be sure".

If you want a good sound, first, treat your room. Dampen it, shape it.. If you spent 10k on stereo and 0 on acoustics, you will not have a good sound no matter what you do. Spend the same amount on acoustics than what you do on you equipment, room makes a lot more differences than gear. Next comes speakers, they are the worst link in the chain by a large margin. Quality costs, still wouldn't go to extremes here either, the changes are again "just to be sure", not always audible.. Then amps, beefy, low noise, A/B. You don't need to spend a huge lot of money but some. Then cables.. Take the 50€ version instead of 300€ or 3000€. Build quality and connectors, durability. Those are the reason to buy more expensive than 5€. Not because of sound quality.. There will always be group of people that will swear they can hear the differences, that's bullcrap. Human ear CAN NOT detect any chances, even meters are having a REALLY hard time getting any changes. You need to either amp up the signal to saturation point, or use frequencies in the Mhz ranges, thousands of times higher than what media needs to get any changes between cheapest crap and high end scams.

Audiophiles can't be convinced they are wrong, they are suffering from the same thing antivax people do: give them facts, they will be even more convinced they are right.

MilkmanDan said:

This goes beyond my knowledge level of signals and waveforms, but it was very interesting anyway.

That being said, OK, I'm sold on the concept that ADC and back doesn't screw up the signal. However, I'm pretty sure that real audiophiles could easily listen to several copies of the same recording at different bitrates and frequencies and correctly identify which ones are higher or better quality with excellent accuracy. I bet that is true even for 16bit vs 24bit, or 192kHz vs 320kHz -- stuff that should be "so good it is impossible to tell the difference".

Since some people that train themselves to have an ear for it CAN detect differences (accurately), the differences must actually be there. If they aren't artifacts of ADC issues, then what are they? I'm guessing compression artifacts?

In a visual version of this, I remember watching digital satellite TV around 10-15 years ago. The digital TV signal was fine and clear -- almost certainly better than what you'd get from an analog OTA antenna. BUT, the satellites used (I believe) mpeg compression to reduce channel bandwidth, and that compression created some artifacts that were easy to notice once somebody pointed them out to you. I specifically remember onscreen people getting "jellyface" anytime someone would nod slowly, or make similar periodic motions. I've got a feeling that some of the artifacts that we (or at least those of us that are real hardcore audiophiles) can notice in MP3 audio files are similar to an audio version of that jellyface kind of issue.

ChaosEngine says...

@VoodooV 5 grand? That's just the cost of the gpus! The whole rig came out at over 10k. And yeah, it's ridiculous, but it's meant to be. It's the Bugatti Veyron of gaming pcs, it's more about seeing what's possible than being actually useful.

@lucky760 I still play heaps of TF2 and it's still pretty popular. The CoD MW guys have moved on to whatever the latest CoD is.

@serosmeg, I played the beta. I have an old Amd quad core and a hd6950 gpu. Neither are close to top of the line these days and the game ran fine.

14 year old girl schools ignorant tv host

newtboy says...

If that is all true (and I read through much of the linked study and made little sense of it since I'm not a nutritionist and only took one semester of advanced molecular biology, it was particularly technical and hard to follow), then golden rice seems to be the exception.
As I read it, 55-70% the RDA was the maximum vitamin A that could be expected, with the range being quite large. (oddly they cite a 200 gram rice dose given in the study has 1.3mg b-carotene/3.8 to get .34mg retinol, then a 100 gram dose is estimated to provide 55-70% EAR , then they say a 50 gram dose, a more reasonable amount for children to eat, would provide the same amount as the 100 gram dose did?) Even if it can supply 1/2 the daily allowance of vitamin A (which I'm not sure it can from the study you cite), that still does not make it 'safe' to release into the 'wild', or 'better' than natural, easy to grow alternatives as unknown long term side effects have not been studied. It may be better than doing nothing, or even better than natural alternatives, but without long term studies we simply can't know. That's my main point.
$10K a year is not much for a farm to make, most small farms make far more than that, but also need to spend all they make to keep going. That limit seems to say they DO intend to charge most farmers for this seed eventually. If that's $10K a year profit, I'm OK with that.
I would say we should hold up potentially life saving technology until we know the unintended side effects, we should not experiment on the needy (or the public in general) and claim it's in their best interest. We certainly should not do it in secret, as in non-labeled gmo's.
Monsanto is not the only bio-tech company that acts like this, just the most public. Most GMO creating bio-techs are pitbulls about protecting their 'intellectual property', even when it floats onto someone's property without their knowledge.
I stand corrected, she did say that. I missed it. I do not claim they don't have higher yields, I think that's their whole point and I think they do a decent job of producing more. I just don't see that higher yields are worth the possible long term damage and I think more, longer term, double blind studies need to be done by disinterested parties. Long term side effects can take a long time to show up, and with something this new to the food source, it deserves careful consideration, not profit driven usage.
Again, 'golden rice' is an exception if you are correct. My limited experience is with Monsanto corn and soy, which seem to be in a different category. Most GMOs are not made with variety, and ARE made to have a clear adaptive advantage, so I made an assumption that 'golden rice' would be the same. My bad. Even with that though, the genes WILL end up mixing with some other non-gmo rice, making it difficult or impossible to ensure your crop is not gmo of that's what you want. They may not dominate, but if they end up causing cancer in 10 years, and by then 99% of rice is 'contaminated', then what? I just think safety (edit: I meant to say forethought) is the better part of valor, and better that a few go without today than open the possibility of all going without tomorrow when patience and thoughtful examination can prove safety. Of course, I'm not going blind of vitamin A deficiency or starving from lack of corn...so perhaps my opinion doesn't matter.
To a few of your other points, if gmo's are safe, prove it (Monsanto and the like) and do it incontrovertibly and publicly, then we'll all want them. If the argument is that 'stupid hippies have convinced everyone they're bad, so we have to sell them in secret', that argument doesn't hold water in my mind. Monsanto could certainly afford a public service campaign if the science was in, but the LONG term studies aren't done yet.
Teaching someone to grow peppers or other vegi's seems easier than modifying a crop and spreading the seeds, it takes about 5 minutes and adds variety. I think that's better than treating them as un-teachable and experimenting on them.
...and I agree with the scientists in sciencemag, destroying the test fields isn't helpful and answers nothing.

Look, I provided a link to a peer-reviewed journal publication showing that Golden Rice is an extremely good source of vitamin A, with one cup providing 50% of the recommended daily amount. I can also provide other citations supporting this claim if you'd like. So, if you have references to actual peer-reviewed scientific research (rather than unfounded claims by anti-GM activists) refuting the efficacy of Golden Rice, let's see them.

As for your claim that the initially free distribution will be rescinded, that seems unlikely. The licenses under which Golden Rice is being distributed explicitly allow farmers to freely save, replant and sell the seeds from their crop for as long as their annual income remains under $10,000. Also, most of the patents relevant to the production of Golden Rice are not internationally valid, so they cannot be used to sue people in third world countries. And all the patents that are internationally valid have been explicitly waived by the patent holders. Is there still some remote possibility that poor farmers will end up getting screwed? I guess. But it seems bizarre to me to just hold up potentially life-saving technology because its possible (though highly unlikely) that it will be used to exploit farmers. Also, I should note that Monstanto does not own Golden Rice. They merely own one of the patents for a process involved in the creation of Golden Rice.

On your third point, Rachel explicitly says "You know that GMO’s actually don’t have higher yields either." It's in the video, at 5:45. Watch it again. So she is claiming quite clearly that they do not produce higher yield, which is false. And it is simply not true that all the research showing higher yield comes from corporations. For instance, see this paper published in Science. The authors do not claim affiliation with any major GM corporation. That's just the tip of the iceberg. There has been volumes of independent research on GMOs.

On your last claim, about monocultures, you are again mistaken. Golden Rice is not a single variety. The International Rice Research Institute (a non-profit, not owned by any major corporation) has created "Golden" versions of hundreds of different rice varieties, so potentially Golden Rice can be as diverse as regular rice. Also, if rice plants are separated by a few feet, then cross-pollination becomes extremely unlikely. Rice is typically self-pollinating. So as long as a small separation is maintained, GM and non-GM crops can be grown in the same location without any significant gene flow between them.

Anyway, gene flow is only a danger if the GM plant has a clear adaptive advantage in its environment (if its pest resistant, e.g.), but that is not the case with Golden Rice, so even with gene flow Golden Rice won't end up dominating non-GM rice evolutionarily.

ChaosEngine says...

@Orz, out of curiosity, I priced this build myself.
http://pcpartpicker.com/p/259dQ

Couldn't find that specific case or the water cooling, but even allowing $2000 (which is ridiculous) for case and cooling, it still comes in under $10k if you build it yourself.

Then add about another $3300 for a 4k monitor (not much point building this thing to run 1080p)

There ya go. 4k gaming for less than $15k.

'95 Miata Review: Hilarious and Informative

chingalera says...

There's a conversion to electric for all you die-hard Miata enthusiasts-For about 10K you can convert a Miata to full-electric and the range and power is pretty impressive-The conversion should get cheaper as the battery technology advances.

The things' a decent car when it's running (response sucks and it rides like a buckboard) but you have to be Asian or a tiny girl to avoid the sensation of being jettisoned to drive an escape pod.

I am guessing the pleasurable experiences in these cars come form folks who have not owned one over 75K miles and have had to deal with any abrupt power loss in hot climates which NO Miata tech can give any conclusive advice as to how to correct.

The cars' pretty much a turd for performance, all it's appeal is in it's boutique position in the auto world and how fucking adorable is is when the tops' down and a cute chicks' driving it.

I'm 5'3",145lbs and I feel like a football player in uniform in the damn thing.

It's really good to see old-fashioned mechanical engineering applied to a hard problem. I'm backing this project - and if you're interested in making access to space cheap, you should too.

Though don't expect to be riding one of these - 10K gravities ... might be a little uncomfortable. (splat)

How a Turbocharger Works

charliem says...

You can afford...being the prime question here.
Most cars these days (read: not performance cars) are made on the cheap.
Forged connecting rods, and billet valves / cam shafts / high tensile head bolts are not cheap, therfore they dont go into the vast majority of modern engines.

Putting a turbo on your engine alone would vastly increase compression ratios, stressing just about every internal part in the car. The poverty pack econo-cars can not handle any more than about 4-6lb's of boost before things start heating up, warping, and shaking themselves apart violently.

Cost to get things up to spec?

erm....well a good set of H beam forged con-rods can cost you anywhere from 600 upwards (generally upwards...a lot upwards), and thats just the part, not including installation. Getting the valves reworked, vavle springs, cam shaft....thats ~2k+ if youre doing it on the cheap.

Then you need an intercooler to take the heat out of the intake air (as the turbo compresses intake air, and therfore heats it up) so as to keep the economy levels up....and piping to go with it, your looking at another 1k at least.

Then you need an ECU mod, piggy back if you can get away with it, around the 1k figure, otherwise a full standalone can cost upwards of 1.5k.

Then you need to program and tune, upwards again of 1.5k.

To turbo a non-turbo economy engine povery-pack car, you are looking at LEAST 5k+, and thats doing it on mega budget, you wont get any reliability or safety out of it.

Before you even get to put the turbo on, which itself is about 300-1.5k depending on what turbine you purchase, you also need a turbo manifold to redirect all of the exhaust gas into a turbo, and have an outlet pipe that allows waste-gate dumps into your exhaust. So you also need to get your cat-back system redone too, which is about 700-1500 to get it done right.

Doing it right? Start counting from 10k....and keep going.

Doing it right would be to upgrade the breaks (bigger discs, bigger calipers, bigger master cylinder), the suspension (coilovers), and doing some serious chassis strengthening to take the increased loads (front/rear sway bar upgrades, front/rear strut tower bars etc..)

Its not cheap unfortunately
