The nice thing about/. is that you have a fair shot of the groupthink being undone by the end of the day (your comment is +4 as I type this). That's why I keep coming back here - there's room for both sides of most arguments, even if just for the entertainment value (man, I miss the young earth creationists who used to occasionally argue here, that was always a hoot).
So, what you're saying is that the C compiler is better Assembly coder than you are. I feel your pain on that one.
Indeed. I spent 5 years supporting a production commercial OS written entirely in assembly (one of many forks that happened when IBM started licensing the source for their old mainframe OS). Today I let a C compiler do it's job on my personal projects.
Can you write faster code than the compiler - sure you can, though it requires a deep understanding. But that code will be crap unmaintainable code. There was a day when C was called a high level language, and in a meaningful way it still is. You can write good maintainable C code that doesn't look optimized and get nearly-perfect assembly that bears little resemblance to the source.
The worst choice in C is to think you need to help the compiler optimize. Seriously, the compiler doesn't care at all whether you write x = x << 1; x += x; or x *= 2; it sees them all the same, so code the one that makes sense in context.
Not if your main properties are back here on Earth. Really, until some distant future of entirely off-Earth sustainability, you need to make nice with at least some Earth government.
Once you can push CHON asteroids around, that's a different story, since then you have both sustainability and military supremacy over Earth.
Well, OTOH that likely means when anything goes wrong with the engine you need an entire new engine. (There was a day when a mechanic would actually repair a busted alternator or starter, instead of part swapping, but that was before I was born.) Wonder how long that lasts.
Same idea as Freenet then. Has OneSwarm had at least some public review and papers on attacks published at conferences? What the creators say about crypto-anything doesn't signify, of course, but if the crypto-geeks have been beating on it then that's pretty cool.
I can only tell the difference (resolution-wise) between my old 480p and my new 1080p set when the actors don't have their HD makeup and I can see their pores. Of course, most of my content is still 480p. The colors on the new set are great, though.
Hey, if 4k really does look better for something other than the demo feed then I'm sure it will catch on. Just so high frame rate never does! Figuring out how to turn off that HFR "smoothing" feature of my new TV was the first thing I did (ack, this looks like The Hobbit, fix it fix it!)
First fellow smart enough to build trucks like Diesel-Electric trains will have that market sewn up in a flash.
I've long been mystified why no one sells these. Pure electric for short trips, but the range/refuel advantages of diesel where needed (and simpler than the "parallel hybrid" cars you see, as the diesel engine is only a generator).
Well, the real problem today is that the primary still takes some time for the explosion to travel, and only certain shapes are possible. The nice thing about the electrical approach is far more freedom to shape the primary, and it all explodes at the same instant. But, yeah, getting clever with the main charge might also yield more, and who knows what cleverness might be possible with normal artillery charges.
The thing is, they're already quite close to optimal. There's just a few % in performance to be gained by any of this.
Freenet is it's own thing. It's a P2P system where everything is encrypted, and you provably have no knowledge of what your box is sharing, so it's a somewhat different P2P architecture.
It's also had a decade of serious crypto review. Though, realistically, if you're just hiding from the MPAA some BT hack that "looks secure to me" is likely all you need, since it makes you no longer the low hanging fruit - but then so does a VPN to somewhere sane.
There's already a neat technology that replaces the primer charge in a tank shell with an electrical system, and delivers slightly better performance. The army has tested it out, but isn't rushing to change over. Change comes slowly with this sort of thing, I guess. Maybe 3D printing would have an advantage as it doesn't require anything new in the tank, but it would still be an inventory/procurement change which I suspect is the real hurdle.
These are zip guns. The plastic printed one is obviously dangerous and unreliable even by the standard of zip guns (which usually start with a pipe from a hardware store and go downhill from there). This is a "look at what's possible" statement, and nothing more, especially in America where you can make a perfectly serviceable AR15 from some kit parts and a CnC mill, and legally so in most places.
The technology will only improve. The plastic gun is just "here's a new way to do this thing we can do in other ways - so far it's useless, but this way is very likely to improve".
However, you can get new tones within a audible frequency and/or shape with tones that are outside audible frequency and/or shape.
I'm trying to parse this, and not succeeding. But if you can only hear a sine wave to 20 kHz, then whatever the rise rate of that wave is, is really the limit. Whatever the actual waveform, the part of it that needs to rise faster than that gets either lost or filtered to some approximation that doesn't rise too fast: e.g., a 20 kHz square or sawtooth wave ends up sounding very close to a sine wave. There are similar limits for the second derivative or amplitude as well (to oversimplify, the eardrum can only move so fast, and can only accelerate so fast, regardless of the waveform).
The math works correctly here. The differences between the original and reconstructed signal are precisely what gets filtered out.
Bone conduction for >20 kHz? That's news to me, and frankly I'm skeptical, but if you can't hear a tone above 20 kHz with any of your senses in the first place, you still can't hear the differences between the original and reconstructed signal with any of your senses.
Certainly the sales materiel for audiophile scam gear is a rich and complex field.
Sure, and half the audiophile ripoff business runs like this: "only people far above average can hear the difference in this high end gear - so can you hear the difference? You're not one of those peons, right?".
Sure, you may be superman, but odds are you're fooling yourself (plus then you're on a quest to find those 6 pieces of media mastered well enough where any of it matters). If you want to buy a 4K TV as living room jewelry (or so that you can imagine your senses superior to the peons), go ahead with your conspicuous consumption, the economy needs the stimulation!
But new technologies catch on when most people can tell the difference.
If you're discussing privacy and P2P, and don't mention Freenet, you're doing it wrong. While Freenet suffers from the network effect (nothing there because people don't use it a vice versa), if privacy should become paramount, Freenet is there waiting. Everything encrypted everywhere, and extremely good assurance of anonymity on upload as long as you don't signal the importance of a given upload until it's done. It's probably the best platform going for leaking stuff the government would be unhappy about.
You need higher sample rates for mixing and mastering, because that can be lossy and you want CD quality left over when you're done, but not for the end product the consumer listens to.
Having seen em side-by side, I disagree. And objecting to Korean products now is like the guys calling Japanese cars "crappy rice burners" in the 70s. Not so much.
I don't have cable and I don't pirate. Between streaming and Netflix's DVDs-by-mail I always have something to watch. Some shows I don't get to see for a while, but that doesn't bother me because I have the shows that I'm just now getting to see. Patience.
just because you can't see an individual pixel does not mean that more, smaller pixels don't produce a more pleasing/realistic image
Yes, that's precisely what it means. (An "individual pixel is a set of lights already.)
it's the same with people who argue that a 44.1kHz is the best sample rate for audio because you can't hear frequencies above 22kHz. there are interactions and harmonics beyond just the audible range that shape the overall sound of music
No, you can't hear those. If you can't hear a sine-wave tone above 20 kHz you can't hear any waveform steeper than that either. That's just how it works - the math and physics are very clear here.
You can still buy plasma TVs. I love the tech - bright, great blacks, better color accuracy, wider color gamut. The only downside these days is higher power consumption (and thus heat). Samsung still makes a full line, and until OLED reaches mainstream I'd go with plasma (you can check them out side-by-side with LCD at a Best Buy or higher-end store).
I'm not saying these people would benefit from ACA, I'm saying their existing plans were cancelled, and they need new plans, even though they liked their own plans and would have kept their own plans. Those are the people who are enraged right now.
But we have a president who think's he's also the legislative branch and can change laws just by saying they've changed, so maybe this will all change with today's announcement.
