Comment QCs will _not_ make existing crypto useless (Score 4, Informative) 128

When (or if) quantum computers become practical they will make existing forms of encryption useless.

Uh, no. It will only make breaking certain popular public-key cryptosystems practical. There are quantum-safe public-key systems, and most symmetric ones are also safe (at best, using a quantum computer with symmetric systems is equivalent to halving the key size — with an obvious way to compensate).

Comment Geist is just a historian, not technologist! (Score 1) 262

Expert opinion? Hardly.
From his bio at

Edward Geist received his Ph.D. in history....His research interests include emergency management in nuclear disasters, Soviet politics and culture, and the history of nuclear power and weapons.

Once again, Slashdot editors fail to do basic vetting of sources. The only qualification for something to be posted here appears to be whether it will work as click-bait. You also have to love how the summary refers to him as "Stanford's Edward Moore Geist". You hear dear readers? He's from Stanford! That means academic authority! So, is he in Stanford's computer science department? Or engineering perhaps?

The Freeman Spogli Institute for International Studies

Oh, wait...

kheldan has a long history of ranting and shamelessly relying on cherrypicked "evidence", as well as hyperbole and other such rhetorical devices to make his "the sky is falling"- and "things were better in the old days"-themed flamebait posts. That he laments the trolling of others is the pinnacle of hypocrisy, and that ought not be lost on moderators here.
In his post higher up in this thread, he reveals an elitist attitude:

I'd almost wish it would go back to being accessible only by Universities, the government, and the military.

This, as well as hi anti-freedom of speech commentary, is in line with the statist views he often expresses.
The real degeneracy of Slashdot and the Internet at large is comprised of the stifling effects on free speech driven by governments and a number number of other institutions, with kheldan being one of their cheerleaders. The best times on Slashdot were not during kheldan's early years, as he would have you believe; I well remember them as the years before he ever joined and brought his odious statist, elitist views.
And kheldan: I've seen innumerous much more thoughtful, eloquent, insightful, and — above all — honest posts on 4chan than the shitposting record you've left here.

Comment Re:Dangerous power (Score 1) 265

Unorthodox treatments are being developed, however. One of the new/experimental treatments for bipolar is ketamine (yes, the same anesthetic commonly used recreationally as a dissociative). It's particularly useful for helping with treatment-refractory depressive phases in bipolar patients, while not making the manic phases any worse. There are a few papers; here's one: There are also recent and ongoing studies using psylocybin (magic mushrooms) to treat major depression and PTSD, as well as at least one study treating PTSD with MDMA (Ecstasy). The interesting thing about these approaches is not that they're also recreational drugs, but that there is indication that these are not indefinite supportive treatments but something more akin to a cure. In the case of psylocybin, specifically, a Johns Hopkins study showed that a single dose in a therapeutic setting can bring on permanent positive personality changes.

Comment Tired of anti-nuclear editors on Slashdot! (Score 1) 242

And of course, one of the links cited is a story in CounterPunch that extensively quotes a Greenpeace official. What is CounterPunch, you might ask? First line in the Wikipedia article about it:

CounterPunch is a monthly magazine published in the United States that covers politics in a manner its editors describe as "muckraking with a radical attitude".[1] It has been described as left-wing by both supporters and detractors.[2][3][4]

This magazine is about as merely "left-wing" as the Death Valley in Mojave is merely "warm" in the summer.

Comment Pettable (Score 1) 225

This news is particularly sad to me on a personal level, as bumblebees are one of the few insects that both tolerate you petting them lightly, and are fuzzy enough to make it rewarding (moths are the other, but they're quite fragile). Unlike honeybees and wasps, they rarely sting, and their slowness cuts the danger even further to making it essentially nil. I've never been stung by a bumblebee. The slow flight also makes it pretty easy to pet them while they're busy feeding on nectar and pollinating, and if you're gentle, they barely react to your touch (just don't touch the wings, obviously).

Comment What about the conductors? (Score 1) 64

While removing the ferromagnetic materials in motors solves one problem, how do they deal with the wires/cables for power and control signals? It doesn't matter if the material they're made of is non-ferromagnetic metal or some other conductor, such as conductive ceramic — the conductors by virtue of being conductors will get current induced in them through both (1) moving through the magnetic field as the robot moves, and (2) from the MRI's RF. I did not see in TFA how they address this. Can someone here explain?

Comment Mod parent up! (Score 1) 53

Parent post is the only post needed in response to this story. If even a quantum computer can merely get a polynomial speedup in the best case, it's kind of silly to suppose that a classical analog computer can get an exponential speedup. And what really grinds my gears is the implication that superturing computation might be possible, which would violate the Bekenstein bound.

Comment I'm glad I'm not a US taxpayer (Score -1, Troll) 316

NASA developed the technology, gave it to Elon Musk for free, and then poured some more cash over His Muskness. What are the American taxpayers getting back?

The US government loaned a huge amount of money to Musk to start his car dealership. They keep paying him for 'green' cars that do not fulfill the payment requirements.

Now, you can spend a shitload of money on a con artist's pet projects, but at some point of time, smart people ask if all that cocksucking and cash showering has a point. Let's hope this point has been reached.

Whom computers would destroy, they must first drive mad.
