Comment Re:Sterile and shattered. (Score 2) 204

One thing you're forgetting is that these stars have very low gravity, so when they throw flares they get a lot further out into space than they do on the sun. Typically the incident radiation will be low for the reasons you described, but when a planet orbits through a flare it gets zapped really hard. Meanwhile, orbiting the sun, we are so unaffected by flares that when we saw one, we thought it was the Russians jamming our radar.

People who get excited about aliens living on planets orbiting dwarf stars are kidding themselves. These stars are a dime a dozen and make up more than 90% of all stars, their light is more strongly affected by planetary transits, and they tend not to gobble up their innermost planets when forming. It's no wonder we find exoplanets around them all the time. But there is nobody interesting living on any of them. You can really only trust type F and G stars with life. Larger stars explode so fast their planets haven't even had time to solidify, and smaller stars have to be hugged so closely that the planet is affected by the star's fickle weather patterns.

No they cannot. They don't read CANBUS. They just talk OBD-II. CANBUS is a very different protocol.

OBD-II is not a protocol. It is a connection standard. It implies one of several electrical connection standards, to go with several different protocols. One of the protocols used on OBD-II is CAN, and one chip which supports CAN is ELM327. The ELM327 supports both SAE J2411 (slow, single wire) and ISO 15765-4 (mandatory in all vehicles in the USA since 2008.)

Is your complaint that ELM327 doesn't speak some other protocol commonly being used between modules? That would be unfortunate.

I had a Panasonic KXP1185, IIRC. Something like that. It would emulate Epson or IBM Proprinter II, and it had very high quality for a dot matrix printer. I used it on my Amiga 500 and handed in many a school paper printed with it. Eventually it died the death of a thousand dogs amen and I binned it.

You have not described a "phenomenon", you made a false claim. Instead of admitting you are wrong, and caught in the act, you attempt to play word games. Cowardice at it's finest.

So you are saying that people only ever use language to establish stable beliefs in propositions, and that they never say anything purely to achieve emotional effect?

As for cowardice, well if it makes you feel less insecure I suppose there's nothing I can do about it. But it's bullshit -- in the epistemic sense of the word -- and it reflects on you more than me.

Remember when HP could compare their products to the actual competition (from the same era, no less) and come out looking... competitive? They have to compare their printer to a fictional dot matrix (what was that actually, anyway?) in order to make it look like something you'd want to buy?

I really should have gone into advertising.

Comment Endocrine hacking has a long history. (Score 2) 129

A long history of not working particularly well. And testosterone hacking is the grand-daddy of them all. You know all those steampunk-y horror stories about rich Victorian eccentrics who go mad because they implanted monkey testicles into themselves in a bid to achieve eternal youth? People actually did that.

There's a thin line... or rather let's say a fork in the road between pseudoscience and science. I think they both start in the same, non-scientific place. And that place is a kind of magical thinking. It's what happens after the initial inspiration that makes the difference between science and pseudoscience.

Testosterone is higher in men than women, an in particular higher in young men, and higher in men who achieve social dominance. It also rises after sexual intercourse. So by magical thinking testosterone must be the "manliness" hormone; it makes you young, vigorous, dominant and sexually potent.

There's nothing wrong with that as a starting point, but in the long history of testosterone hacking it hasn't worked out, except for gaining muscle mass in conjunction with resistance training. Sure if you treat men with a testosterone blocker they'll eventually lose interest in sex, men generally have less sex as they get older, and at the same time their testosterone levels decrease. So it's natural to jump to the conclusion of a chain of causality: worn out old glands put out less testosterone, and that causes a reduction in interest in sex. But if you actually test that hypothesis, it doesn't work out: individuals with least decline in testosterone levels actually have less sex than their normal counterparts. The normal decline isn't large enough to produce on its own any measurable effect in interest in sex. So if your interest in sex is dropping as you get older, look elsewhere for the cause.

This is the danger of calling testosterone "the male sex hormone", as if God had a punch list of features He wanted and implemented each feature with a single steroid compound that works in isolation from everything else. Yes, testosterone is involved in masculinization of adolescents, but it's not as simple as the more testosterone you are, the more male you are. The endocrine system is complex and dynamic, responding to internal and external changes -- including aging. Both men and women have and need testosterone and estrogen, in ways we don't fully understand yet.

If you want to get the most out of your life, eat a variety of real food in moderation, exercise, sleep, and in general alternate stress with rest. The ancient Greeks could have told you that, and in thousands of years we have not been able yet to improve on that as far as lifestyle advice is concerned. Go to your doctor if you're sick or injured, or even for a testosterone treatement if you have abnormally low testosterone for your age. But don't go to the doctor for a magic pill that will make you youthful, manly, sexy and dynamic. All that's up to you.

Comment Re:All of this has happened before... (Score 3, Informative) 238

That's the way it looks to enthusiasts, but that's not what Intel has been doing. About a decade ago, we hit the point where processors were "fast enough" for mainstream tasks. People stopped buying i5 and i7 processors, in favor of i3, Celeron, and Pentium. For the last 10 years, only enthusiasts and gamers have cared about improved performance. The vast majority of the market cared more about power consumption. Intel hasn't been worried about AMD, but they were scared to death of ARM. They rushed to bring Atom to market to keep the low-end on x86/x64, instead of moving to ARM.

So they haven't been resting on their laurels. They've been working hard at reducing power consumption. That's what really hurt AMD after they lost their performance lead. For a few years AMD still offered more performance per Watt, making AMD the natural choice for moderate-load servers and systems meant to be left on 24/7. But Intel soon beat AMD there, taking away AMD's only advantage. (That's when AMD used their ATI acquisition to integrate a GPU which could beat Intel's integrated GPU - essentially carving out a spot in the low-price gamer market.)

A Core 2 Duo system would use about 70 Watts idle, 150 Watts under load. A Sandy Bridge system would use about 45 Watts idle, 120 Watts under load. A modern Skylake system uses about 35 Watts idle, 80 Watts under load. Subtract the 20-30 Watts consumed by components other than the CPU, and the reduction in CPU power consumption over the last 10 years has been remarkable.

Comment Re:About time. (Score 1) 238

I remember the heyday where AMD actually overtook Intel. Their CPUs were actually better and cheaper.

Not cheaper by much. I remember comments here asking why if AMD had overtaken Intel, why were their high-end CPUs now almost as expensive as Intel's had been. The replies stating that if you're the market leader, you can set your prices as high as you want.

I think that's where they screwed up. Instead of keeping their prices low so they could gain market share, they raised their prices to try to recoup their R&D expenses. If they'd aimed for market share, that would've resulted in much greater industry support - AMD motherboards, chipsets, compatible memory, retailers stocking their CPUs, brand names offering more models using AMD processors, etc. Instead they chose short-term gains over long-term, meaning Intel had an easy time reasserting its dominance as soon as they managed to convert their laptop CPU cores to desktop use.

If they're keeping the price down at half Intel's prices, it sounds like they learned their lesson.
