Shooting At Canadian Parliament

Prune Re:Good thing Canada's pretty much a "Gun Free" zo (512 comments)

It's a gun free zone for all legal practical purposes because you're not allowed to carry in most circumstances. Outside of hunting (with hunting rifles only), your guns can be either in your home, at the shooting range, or on your person, bagged, and only if you're on or reasonably near a direct path between your home and the shooting range. Many types of guns are restricted to only your home, and many cannot be possessed at all.

Shooting At Canadian Parliament

Prune Re:Good thing Canada's pretty much a "Gun Free" zo (512 comments)

Gun deaths are still not about guns; they're about culture. Switzerland is proof. Few countries have more guns per capita, yet gun violence is rare there. Why? Proper training of a citizen militia is a factor, but not a sufficient one. Its cultural differences with the US has everything to do with it, not gun ownership levels, which are comparable.

Shooting At Canadian Parliament

Prune Re:Why (512 comments)

Mod parent down for lying. Soldiers are only legitimate targets for other soldiers or organized, uniformed (or at least "having a fixed distinctive sign recognizable at a distance") militia members controlled by a responsible commanding officer. I suggest you check Article 4 of the Third Geneva Convention for the requirements of being a lawful combatant (there are many others beyond the couple I referenced). And let's not even go into the fact that the person in question is a citizen of the same country the soldier is of and there is not a state of civil war.

Shooting At Canadian Parliament

Prune Re:Parliment Hill != The White House (512 comments)

Actually, he's only PM because he got the most votes. I promise you most of us who voted Conservative in the lsat three federal elections voted for Harper and not just his party. It's the same phenomenon that resulted in Liberal seats in Parliament getting decimated last time--it's not because of Liberal party policy, but the perceived arrogance of their past actions that Ignatieff conveniently came to personify so well by his demeanor. It's also the same in the case of the NDP's surge--it was all Layton, something that Mulcair can't hope to duplicate.

Shooting At Canadian Parliament

Prune Re:Parliment Hill != The White House (512 comments)

Your post is wrong on several levels. The Queen is both relevant and wanted. Polls continue to show the majority of Canadians are pro-monarchy. Recent legal challenges objecting to having to swear allegiance to the Queen when an immigrant goes through a citizenship ceremony were rejected by the courts with prejudice. Beyond being a personification of the state, the Queen's direct representative, the governor general, does in fact carry power in practical terms, even if it is rarely used. When Harper advised the governor general to prorogue parliament, or when Trudeau advised him to invoke the War Measures Act during the October Crisis, the governor generals had the constitutional power to refuse, even though in any given instance it's unlikely due to custom.

Cell Transplant Allows Paralyzed Man To Walk

He knows, and he's doing it on purpose. i kan reed is a well known pathological liar on slashdot. The best approach is the same one as with trolls: don't feed it.

Prune Re:I'm still waiting... (156 comments)

i kan reed apparently assumes others can't read, because he consistently gets busted lying and yet keeps deploying that same doomed tactic. He already got called out on it more than once in this discussion alone. As the approach is clearly failing, yet he persists, one must suspect a pathological origin of the urge.

Prune Re:I'm still waiting... (156 comments)

In the grand scheme of things, it doesn't mean anything at all.

Since meaning is as subjective a thing as can be, consciousness actually tops the list, for it provides the very substrate for meaning.

Google Leads $542m Funding Round For Augmented Reality Wearables Company

Prune Re:Better than a wtch (38 comments)

The variable focal depth issue was solved long, long ago by microlens arrays. Current ultra-high resolution displays make this approach very practical, as you can have 8x8 patches behind each microlens and still have decent overall 2D resolution. As for the variable opacity, just use DLP tech, as was (is?) fashionable in some projectors.

Prune Re:Another dorky one? (38 comments)

Your post started off good, noting the issue of focus (the actual depth cue related to focus, though, is not focus itself, but accommodation--the response of the eye to defocus) which is often ignored and people commonly only address stereopsis and motion parallax. However, it then took a couple of wrong turns. First is the issue of color reproduction. Humans are trichromats. We have three types of cone cells in our retinas, and a variant of RGB (read: color space based on only three primaries) can reproduce the full CIE perceptual color gamut. Prototype display systems that do just that exist, and I've seen more than one demoed at SIGGRAPH over the past decade. Perhaps your confusion stems from the very different situation with lighting, where the full spectral response of the luminaire matters because the resultant perceived colors are the product of the light spectrum and the lit surface spectral reflectance, convolved with the retinal cone cell response curves, and so two lights with the same whitepoint but different spectra can result in a situation where two surfaces are perceived to have the same color under one of the lights, but different colors under the other. However, this does not apply to emissive displays, where three primaries is all you need, as long as the choice in primaries is right and the maximum saturation achievable is sufficient. The second wrong turn is in regards to contrast. High dynamic range displays exceeding the dynamic range of the human eye have been around for quite a few years--just search for BrightSide technologies. I still remember the initial prototype at the graphics lab at UBC (where I did my masters). So all the issues have been individually resolved; it's just a matter of putting it all together.

Isaac Asimov: How Do People Get New Ideas?

Even among the circles of psychonauts, McKenna is oft regarded as kooky at best. I guess it is possible to use DMT too much after all.

Isaac Asimov: How Do People Get New Ideas?

Prune Re:He, Him, His (145 comments)

I can't tell if you're just name dropping, but Conrad isn't exactly known for his character development. His character's dialogues, especially, are often the subject of criticism. Conrad's strengths lie elsewhere, much of that being the artistic, and specifically, impressionist approach to being a novelist (consistent with his own claims in the preface to The Nigger of the Narcissus). For a contemporaneous author of the same caliber who excels in bringing to life elaborate characters and delves into their psyches in a way complementary to Conrad, I look to Henry James.

There is one simple and crucial difference between the cover photo you reference and the leaked private ones: consent to publish. This is a quintessential aspect of privacy of any kind, so I'm surprised so few acknowledge it.

First commercial carbon capture project is failing

Prune (557140) writes "A Saskatchewan report that the world's first commercial carbon capture project is failing could be grave news for those involved in efforts to blunt humanity's contribution to climate change.
