Re: Wait for it...

Stop moving the goalpost. You are just making my point that self-defence is nowhere near granted by courts when you shoot a burglar invading your home, not even when they start punching and kicking you or threatening you with knives. You will be facing the full burden of proof if you do, same as the criminals.

Save for a few countries, Europe tends against anything like a Castle Doctrine, the authorities' official advice is all too often that you are expected to hide and run from attackers no matter the circumstances, and to never stand your ground - or you will get sentenced.

T'was easier done earlier with the 6.0U2m

The VCSA migration is apparently less perilous when going 5.5 to 6.0, than all the way 5.5 to 6.5.

The checklist I've accrued after a number of failed attempts to 6.5:

Check your DNS (forward and reverse)

Remove vUM

Revert to self-signed certs for the transition, you'll customize them again later

Check your DNS, I mean it

Keep either IPv4 or IPv6 net config on the source vCenter server, not both

Make sure your vCenter's vNIC portgroup is ephemeral if on a vDS, or duplicate it into a standard vSwitch

Ensure the SSO admin account (default) is in the DCadmins SSO group (default too)

Re: Cryptocurrency

Update posted by Coinbase:

"We have determined that the erroneous credit and debit charges are the result of Visa reversing and recharging transactions. This was not done by Coinbase. We are working with Visa to ensure all affected customers are reimbursed.

Over the last few months, large banks and card issuers requested that card networks change the MCC for purchases of digital currency. Visa changed the MCC for digital currency purchases to a code that allows large banks and card issuers to charge consumers additional fees."

More details on what exactly is meant here: https://www.thebalance.com/what-s-a-credit-card-cash-advance-960691

TL;DR: last year VISA and major banks implemented a new MCC that allowed them to charge "cash advance" fees when their card holders buy cryptos, by unusually re-qualifying those transactions as ATM cash withdrawals.

Where's your God^Hregulation now ? Oh right, it is busy polishing a few banksters' dicks so they can rear-end you better when you make purchases with a credit card. But, hey, let's bash on libertarians for no good reason, because muh political agenda.

French woman gets €800 a month for electromagnetic-field 'disability'

"In a statement on Wednesday, Étienne Cendrier, Robin des Toits spokesman, hailed the news as a victory, saying: “We can no longer say that it is a psychiatric illness.”

Well he is free to delude himself, but the court statement clearly swept aside claims that it has to do with electromagnetic waves. What the judge granted, is that the syndrome is really harming the claimant - she is not pretending to be sick, she really is so sick she cannot hold a regular job. AFAIC it's all just nocebo effect, given how the sufferers are only harmed by antennas they can see (whether those are powered on or not), and never by those hidden from their sight.

What is making the claimant sick is an entirely different issue, which was not addressed by the court. In fact I haven't heard of a single success in assigning damages in civil court over any claim of harm from electromagnetic waves. At most, there was one case of mobile mast installation being postponed until final decision by a court over alleged "potential future harm".

Re: Not implausible

I get that a lot from my old Macbook. Plug it in, let it warm up, then slide your hand over the flat part left from the trackpad, and you will very strongly feel the "field" (as you call it). It's a very weird feeling - it's as if you're rapping your hand over a wood plank that is vibrating quickly, except your skin reports it as smooth contact.

And it does not happen when the laptop is running on battery or when you and the power line are both properly grounded, because it's actually poor grounding leaking a little power back and playing with your nerves. Nothing to do with RF. And the effect is so much stronger on the Macbook just because the entire case is made of metal and conducive.

Try and test it ! It's fun, at least as long as you don't get burns.

Lies, damn pies and obesity statistics: We're NOT a nation of fatties

Jesrad

Re: As a fatter person

One persistent myth in nutrition that needs to die, is that calories' total net "offset" determines weight loss or gain. It's the other way around: those calories that get snatched from your bloodstream and sequestered in your adipocytes become unavailable for doing anything. In simpler words, fattening up makes you lethargic or increases your appetite to compensate for the calories locked away (or a combination of both).

The good news is, it works both ways. In the study detailed here: http://www.fathead-movie.com/index.php/2011/02/01/fat-kids-and-thermodynamics/ giving an insulin-blocking drug to obese kids spontaneously made them spring outside and play instead of staying in front of the TV. All because the same calories that used to go stack up in their slab had become available for their muscles to use up.

Thanks for mentionning this. I too healed from obesity and diabetes on a LHCF diet, no more health problems now. And so did the dozen people that I got along on this.

The core of the argument in the article is that Brits eat less and exercize more and more to the recommendations of their gov, yet see no health gain. Figures, maybe the gov advice is wrong in the first place eh ?

The problem is that science has been early-fossilized by state intervention, as a government appointed panel of experts just cannot admit being wrong on anything, ever. They've steadfastly refuse to incorporate any of the results of recent medical research on the subject and keep alive myths from the 60s and 70s.

"as we can also see at present the European Central Bank isn't doing anything of this sort. They actually raised interest rates in the middle of the recession: just like the Fed did in the 1930s. They've not done any QE"

Have you been in a coma the last few years ? Of course the ECB eased the monetary supply: it may not have directly bought treasury bonds from the EU member states, but it did indirectly have them bought by the european banks using newly created euros - which amounts to the same as what the FED did. The only difference is the FED depresses treasuries' rates (and indirectly all other bonds' rates) while the ECB is boosting bank funds' liquidity.

In the time the FED's balance sheet grew by 2 trillion dollars, the ECB's grew by almost the same amount: 1.755 trillion dollars. How is that NOT a QE ?

Re: non story

"Female meshes abound. Add an extra mesh option with the same animation rigs, and job done."

A fine job indeed, too, if you assume the long, tedious, extra work of remaking the textures for that mesh, and also for every single apparel option, accessory, weapon, etc. that comes in the game and will combine with it - unless you're fine with insulting every female gamer in the world with a very non-matching texture of a guy's face and musculature superimposed (and way off) over a gal's body...

A fine job, yes, surely, with a wrong-scaled mesh that will look silly using animations made for a mesh where the joints are off, the bones are different length, the centers of mass (and thus, inertia of body in movement) are off, the attachment nodes for weapons and accessories are off and the wrong scale, etc.

A "female" character with very male grunt sounds when jumping, falling, hurting, etc. With lots of silly clipping, 90s style, with feet hovering off ground or ankle-deep in it depending on the action, "roller-skating" on invisible free-wheels as it walks and runs, with hands that lift or grab things at a distance by magic and wobbly fuse into walls and scales when climbing, etc. A testament to the long-standing quality of character animation in the Assassin's Creed series, indeed.

Mr Bailey I'm afraid you know very little of the video-game industry. I'm afraid you also know very little about female gamers, because offering a satisfactory variety of options for dressing a female character takes a LOT more work than just than fiddling with a male mesh and adjusting some proportions. And few things scream "shoddy" louder to girls than seeing leg / skirt polygon clipping on female characters in 3D videogames.

All men are part of a PURE GENETIC ELITE, says geno-science bloke

Jesrad

Re: Some clarification

Lyonisation ensures only one of the two Xs is enabled in each cell in women, so the supposed genetic superiority you allude to is very relative. Women have more bulk genetic data (volume) but less genetic diversity (number of genes) since most of the extra DNA is redundant to begin with, whereas the NRY genes on the Y chromosome hold genetic code that is nowhere to be found in any X.

Also, there's a misunderstanding about the evolution of the Y chromosome: as reported in Wikipedia, "with a 30% difference between humans and chimpanzees, the Y chromosome is one of the fastest evolving parts of the human genome". So, no, sorry ladies, men are actually further from chimps than women themselves are. What has had little evolution over the last 25 million years is the structure and gene composition of this chromosome, a proof of its remarkable stability and the reason why this genetic study is interesting news, even though the content of those genes evolved faster than any other piece of DNA we have.

Re: Gosh, I wonder why.

"there is no government funding for parks and 'nice places' "

Actually there is, LL has a number of their own regions integrated in every continent, and most of it is parks and nice meeting places, and free building zones. There is in particular the vast sea that joins the eastern continents, for one. Little islands, a gorgeous lighthouse, and lots of ocean, all of it public access and use.

But your underlying point remains true: given the high price of acreage in SL there's little incentive for players to just have a lot of nice-looking land that is not put to commercial use. LL mitigated this a tiny bit but introducing quarter-price regions, but those just went to low-cost demand instead of feeding any need for more natural or just-for-the-beauty-of-it options.

There is simply too little granularity, because of the fixed 256x256m size of regions and hardcoded prim/surface values... which makes little sense, given how size of land and constructions is completely arbitrary beyond the absolute number of objects. There is no technical obstacle to making 32+ km sized single regions that have a very low prim count limit, and sharding those by the dozen on a single server. But they won't do it, somehow.

Another thing sorely missing from SL is that it's not making use of sunken-cost processing power, bandwidth and storage space: namely, that of the player base. Give them an option to allocate some of their already paid-for computer-hold, and they'll happily convert it to more virtual acreage. There are many distributed algorithms and existing, proven protocols, that could make it possible for the players themselves to host part of the Grid. The virtual reality Solipsis concept goes as far as having no central server at all, hosting its worlds entirely on the cloud-ified computers of the users themselves.

Official science: High heels make you sexy

Or the other way 'round

The researchers assume that the high heels make the wearer more feminine because they affect the gait and balance of wearers, but it could very well be the other way around: that the viewers have been taught by their environment that the specific gait and balance of walking in high heels are to be associated with feminity.

So which is it really:

high heels -> specific gait -> perceived feminity

Re: Second Life

SL is far from successful. I say this as a long-time player (8+ years). It had its peak somewhere around 2007, and since then its population and economy just kept declining: first-time users nowadays mostly take a look then leave forever, the long-standing (oligopolist) land business is surviving merely by siphoning off the capital investment from wide-eyed newcomers who believe they can just plop down a BIAB and start making money, persist for a few months then eat the cost and leave. The best a new business-oriented player can do now is mostly catch other newcomers' first few bucks before they go for good. Decline has turned the whole thing into a sort of big Ponzi scheme fed by a quickening life-and-death cycle of true end-users. In simpler words, SL is coasting on the momentum from its accumulated capital of better years.

Even at the height of it, you could count on your hands the number of players truly making a living from their SL activity (most of whom I met), and I was never one of them. I earned enough from SL to buy myself a brand new car though, so I can say I got close.

Its architecture is still unscalable, as it ever was. There have been improvements (making the protocol RESTful, for one) but it's still so bloated only a full rewrite of the server could fix it. And the UI suicide the SL viewer 2 was ? Just another nail in the coffin.

Re: Ah memories...

IIRC IBM had 4 private islands that had public access, that size of land amounted at the time to a front payment of $4500 plus a monthly fee of 4x$299 = $1196. They may have as many hidden regions too.

I bet they paid a lot more on staffing alone (providing content for the islands, which I remember was done through SL contractors - really the smartest option ; and populating the islands with at least a couple PR employees).

I had 5 such islands at some point. SL was never more than a game to me, and a lucrative one at that - it paid me a brand new car. I bailed out when Linden Labs announced it'd enforce both US federal regulations on sexualized content and casino games, and the EU's VAT to all european players.

What made us human? Being armed with lethal ranged weapons

Genetic evidence is so far inconclusive on exactly what amount and what form of interbreeding occured between Sapiens, Neandertals and Denisovans. We have significant shared nuclear DNA, but no shared mitochondrial DNA, with both of them. Some think that all female Sapiens were absolutely unable to conceive from N or D males for some reason, but not the other way around. IMO this is better explained by the overall one-sided migration of Sapiens outward from Africa combined with the old tradition of sending young adult males to marry into the neighbouring tribes to strengthen social ties with them and reduce interbreeding within the tribe itself. After all, the transition lasted much longer than all of recorded history, so that's plenty of time for a even such a slow swamping to show that much of an effect.

As for the disappearance of Ns we have not found any evidence of mass homicides occurring between Neandertals and Sapiens. The best archeological traces we have show that, basically, our ancestors migrated into Europe right after Neandertals went extinct there, or maybe just as they went extinct. The more probable cause of this extinction, IMO, is climate change, and I think this is also why Sapiens started migrating all over the world in that same period. Modern humans are savannah pack hunter-gatherers, evolutionarily speaking, so a warming world may have been an invitation to them. On the other hand Neandertals had specific adaptations to their environment, in particular cold weather.

Anyway, we don't know for sure.

I cannot quite answer on the history of rape, but we now know war is a recent invention / trait of humans: in "the birth of war" published by Natural History (Jul/Aug 2003, Vol. 112, Issue 6), Ferguson&Brian estimate from skeleton remains that warfare or at the very least mass homicide appeared roughly 8000 years ago, at the same time as agriculture.

Re: There are no 'killer' Windows applications any more

In this age of dynamic binary translation and API wrappers, Mac users were able to play Skyrim the day it was released thanks to Wine-X or Cider "ports". Why bother installing a bloated OS into a VM when you can have your app running seamlessly and at quasi-native speed, directly in the native env ?

The move to Intel chips was a success back in the days mostly because Motorola (and to a lesser extent, IBM) had failed to keep up in processing power. It was painfully obvious then that Macs were lacking in performance and no Photoshop tricks could hide that sinking feeling in the fans' minds. The performance boost that came with the first Macintels certainly helped the architecture transition (universal binaries, Rosetta binary translation) go smoothly from the user viewpoint.

Somehow I doubt it would go as well, moving from Core iXXXX to Ax.

It makes more sense that Apple will fuse its OS X branches, until the very same apps can run on anything they produce using the same mechanism as before (universal binaries). Expect it to go a lot more smoothly than the Win8 transition on the Microsoft side. Then they can consider ditching Intel.

Look to Fission instead

I still think braking radiation dooms the ITER project and any form of magnetic containment fusion from ever producing net power.

Look to fission instead: there is a tiny but dedicated group supporting molten salt reactor using Thorium, which is very cheap and very abundant. Thorium is bred by the reactor into U233 then burned, in a continuous operation.

Molten salt reactors run continuously, no need to stop them to refuel or remove the fission products as they can be respectively dissolved and pumped out of the liquide fluoride while it is running. Plus it is not pressurized (it's typically run below ambient pressure for safety), and cannot fail à la Tchernobyl. And to top it off, its waste products have a half-life in the tens of years only. At an estimated 1$/W it should be very competitive with wind and solar power, too. Oh, and it can be designed around a breeding factor of exactly 1.0 so proliferation risk is seriously reduced, plus there exists not even plans for nuclear weapons using Uranium-233 anyway.

Oak Ridge National Laboratory had a working reactor of this type producing 7.4 MW for several years in the 60s. The design is compact and can be scaled down, in fact one such reactor was built and tested as the power plant for aircraft. Fuji has planned to build a 100 MWe such reactor (FUJI MSR) in the near future.

It even has an aesthetic side: yes, I think there is something beautiful in the life arc of some stupid person meeting an equally stupid and timely death through a thoroughly free chain of thinking and acting, without malicious interference with his or her thinking and acting from outside, unto reaching the pointless conclusion.

Man's condition is stupid and tragic because he's free to develop his own purpose and justification for existing but incapable of perfection at that task, so fulfilling this existence one way or another will on average be just as stupid and tragic as we are as a species. The most we can do is to avoid one's stupid chosen purpose in life from affecting another's equally stupid chosen purpose in life, so as to maintain everyone's aesthetic standing. When applying this thinking to people bent on killing each other, it means avoiding collateral damage. In that sense, within this understanding of life, smart bullets and sniping are beautiful.

Of course, a duel at dawn between just the couple persons who'd initiate wars in the first place, would be even more beautiful. But those people tend not to play fair.

Miracle airship tech sustained by DARPA pork trickle

Jesrad
Alien

Solutions, solutions...

A simple solution, when using a rigid frame, is to inflate a balloon of air inside the buoyant enveloppe, which decreases the buoyancy by augmenting the density of the helium through simple pressurization. This is the typical solution used on modern airships.

There is another problem than buoyancy with airships, though, it is that of maximum velocity against lifting capacity. Lifting heavy loads requires lots of volume, and lots of volume mean big dynamic drag that reduces top speed. One solution was to use a dynamically-lifting shape for the buoyant enveloppe, as for the Dynalifter and its ancestors. But then it just comes down to trading maximum hovering altitude against top speed.

A solution to this problem is to use a variable-volume dynamically-lifting shape for the enveloppe. As the speed increases the volume can be decreased (pressurizing the lifting gas) and boyant lift exchanged for dynamic lift, saving on dynamic drag, when taking off the enveloppe can be expanded up to the ambient pressure, and when offloading cargo the enveloppe can be repressurized again to lose buoyancy and stay on the ground.

But there is currently no engineering method for building a volume-changing aerodynamic enveloppe that can self-pressurize like this.

Re: Supersonic tips

Supersonic tips are a lot less efficient than subsonic, because of the energy lost to the shockwaves ; and because supersonic lift is an entirely different beast than subsonic lift, requiring another (usually thinner) type of blade profile to be worth the extra effort. In addition the supersonic schockwaves can cause serious damage to the blade's material, generating creaks and cavities, leading to early failure. At higher, hypersonic, speeds there may even occur various undesirable chemical reactions when the air molecules become ionised and possibly split into their atomic constituents, damaging the surface some more. That is, provided the friction heat hasn't already melted or burned the blades.
