Comment Heh, haven't heard that name in a while. (Score 1) 24

I used to follow some of what The Jester wrote. There are a number of people out there who think he's overrated, more brag than anything else. Still, I saw some pretty clever things out of him. For example, at one point he was going after some other hacking collective (I don't recall which one), and he announced a successful attack against them and posted a list of all of their names and real IP addresses. Only, the list wasn't real. Instead, anyone who tried to download the list had their connection logged and probed, an exploit used to trigger the computer to make a (real) TCP connection back to one of his computers, and a number of automated attacks launched against targets it considered particularly suspect (for example, if there was evidence of being logged into a known member twitter account). I.e., it wasn't actually a list of suspects, it was bait to build a list of suspects. I think he did the same trick with QR codes later.

Apparently I missed the part of this story where these manufacturers are trying to take your guns.

And on that subject, how many people have you guys turned out to the polls every time warning that the Democrats were with some imminent plan to take all your guns the second they take office? How did that turn out? Apparently I missed the massive seizure of privately owned weapons that you guys are constantly talking about.

Here's some past examples of True Pundit "journalism" for you.

  * Clinton secretly wearing mini stealth earbud to receive answers from her team during the debate

  * Clinton was using secret hand signals to tell Lester Holt what to say

  * Claims Clinton had a medical issue during the debate and Trump mouthed the word "Seizure"

  * Offers a $1m reward (as if a website like True Pundit has $1m) for Clinton's medical records, suggesting that she has "dementia, post-concussion syndrome, Parkinson’s disease, brain tumor, brain injury, complex partial seizures, and/or many more alleged ailments" and is followed by a doctor disguised as a Secret Service agent carrying an autoinjector of diazepam.

Um, have you seen their Twitter feed lately? It's a nonstop feed of anti-Clinton propaganda, half of it retweets, a lot of the claims so bad that even Wikileaks supporters on the Wikileaks Reddit sub have been calling them out on it. It's morphed into Breitbart.

They're even repeating Trump's "rigged election" lines:

There is no US election. There is power consolidation. Rigged primary, rigged media and rigged 'pied piper' candidate drive consolidation.

Comment Re:'Genuine' is how luxury brands protect themselv (Score 1) 190

Knockoff items are poorly made, badly insulated, and are a fire hazard. They often don't meet spec, so they don't perform as well.

If you want to make a knockoff item, Apple can't stop you, but they DO want to stop people from thinking they're buying Apple cables, which ARE tested and manufactured to a higher standard. Apple is presumably willing to stand behind their products and take the flak if they're bad (I had a laptop charger replaced under a recall), but they can't be expected to stand behind the product of someone else using their branding.

So the problem really is on Amazon's end, because they're the ones giving worldwide distribution and implicit authenticity to these fake products.

I've bought cables from Anker that were MFi certified, and they were cheaper than Apple's and just as good (maybe better? Time will tell). It's not that Apple doesn't let other people make cables, but they're expected to meet spec.

Anyway, your post is basically garbage. Yes, we all know that Apple is in some respects a Veblen good, but their products *do* actually have sufficient merit that ordinary people are willing to buy them.

Yes. I've run numbers before. No, I'm not going to be bothered to do them again for a Slashdot chat on a thread that's rapidly becoming out of date. Feel free to do your own if you doubt me. Take a sampling of solar plants with a realistic capacity factor and a sampling of hydro plants with a realistic capacity factor, and compare. You'll need a broader sampling on hydro because solar thermal plants are "fairly" consistent (with the exception of compact linear fresnel plants, of which last I checked there was only one), while hydro reservoir sizes vary wildly for a given output.

No, a RTG is distinctly different from a nuclear reactor in almost every single way. They do not involve chain reactions. They do not involve neutrons to any significant degree. Moderation, cross section calculations, etc don't even come into play. It's just a ball of material that stays hot due to capturing its own alphas. RTGs are not considered nuclear reactors. There is no wiggle room on this; they're an entirely different class of spacecraft power systems.

RTGs scale down quite well. They're also, however, about as far on the opposite side of the affordability spectrum as you could possibly get.

There have been actual nuclear reactors used on spacecraft in the past, as I wrote, primarily by the Soviets. But they're anything what you'd consider a cost effective design for civilian power generation.

Higher fissile number density = higher enrichment = nonstarter. Fine for submarines, not for civilian power. Re, reflector, you still have to deal with free path issues when determining overall reactor size. The more you're spending on inert mass relative to how much power you're getting, the worse your economics. Plus your reflector is contributing to (n, gamma) and other neutron consuming reactions (although it's possible to use a moderator that you need anyway (say graphite) as a reflector... although there are issues with that as well to deal with)

You'll note that I mentioned and agreed with the mass production argument - if fission power is going to have an actually sustainable renaissance, I would expect modular reactors to be the means. But I nonetheless questioned whether that could be enough to overcome the basic issues on top of the additional challenges that a small modular reactor imposes.

Energy density (with respect to time) - J/m^2-s or equivalent.

As for "Who cares?" The GP for one. Me for two. Most people on Earth as well. The more land that is used up, the less you have for other purposes, be that for humans (agriculture, forestry, mining, grazing, etc) or natural habitat. It hits doubly that reservoirs target land defined most notably by the following characteristics:

1) Large river
2) Deep ravine/basin
3) Significant altitude change

In short, they often tend to be the areas most important to wildlife, often locally-unique habitats, as well as the most scenic areas within a given location - areas responsible as well for significant mobilization of sediment and oxygenation of water.

Solar, by contrast benefits most from environments full of endless identical flat wastelands. The more mundane and barren, the better.
