Powering up the Godwiniser already, eh?
Oh yeah you think?
Not even talking hypothetically.
Wrecking a few countries and being onboard for wrecking a few countries using rank propaganda and crying liberals from the safety of the desk, then cackling about it on TV?
I don't know what you need then.
People have been hanging from rafters for far, far less.
As for the "mildly corrupt bureaucrat" .. HA HA!
The light from Proxima has a colour temperature of about 3000K which is rather whiter than a halogen light bulb.
Quite so, but why is it so red on the snaps, then?
They're probably thinking "should I vote for the personality-free, mildly corrupt bureaucrat for four more years of the same
I'm sorry, that's an Eichmann-level type of bureaucrat. Banality of evil and all that (which Hillary has publicly sworn to eradicate, imagine that)
Another 4 years of Bushbama WILL kill us, as Russia and China are next.
Your probes fly to the halfway point, then flip over 180 degrees sail now acts as a drag chute as you approach target star and slow down. Larger ship uses ion drives to the halfway point, flip over then decelerate until space normal maneuvering possible.
Excuse me, we are now reaching no-reaction-mass needed Star Wars Fantasy Manoeuvering.
And how exactly is that "drag chute" thing going to work?
An excellent question. Does anyone know anything about the flaring behaviour of Red Dwarfs?
> a perversion about inseminating cows and anal probing americans
Actually, it's about MUTILATING cows (and other livestock) and ABDUCTING (anal probing is generally not on the books) not only Murricans.
Additionally, it's not a "perversion". Trained tour guides from Zeta Reticuli routinely sell these activities under the heading of "THE LULZ". Confusing the locals has been an ancient tradition since at least Ghrn'Harrr the Contorter.
Though for Deadalus, I dont think there is a viable fusion motor yet.
"Hence, a habitable rocky planet around Proxima would be the most natural location to where our civilization could aspire to move after the Sun will die, five billion years from now."
100% sure civilization will be done and dusted several orders of magnitude earlier, if we are lucky.
Maybe the machines (possibly "semi-biological", after all protein is excellent for building various stuff) will inherit the solar system. I hope so, one always wants to leave the universe a bit more inhabited.
Additionally, Earth will become non-habitable in about 600 million years as all the CO2 gets scrubbed out of the atmosphere and the habitable zone moves outwards as the Sun heats up. Interesting times for a last run of the evolutionary process.
> Ok to go. I'm OK to GO.
It always sounded suspiciously like hot sex words to me.
Maybe that's what interstellar travel is all about, too.
Well, that's having the Iran story a bit of arse-backwards, but thanks for trying and being open to propaganda by the usual Neocon suspects.
> we had a chance to back that uprising against the mullahs
You guys fucked Iran over after the first revolution, please stay out, mmokay?
This is an American mission.
First drop stuff, find out if someone complains later.
Suddenly, swallowing another swig of beer, van Dokkum realized he might know of a way out of this predicament. He’d made a hobby of wildlife photography (he recently published a collection of photos of dragonflies), and kept up with camera trends. “I had heard about these awesome new telephoto lenses,” he says. The Japanese optics corporation Canon had started producing high-end lenses coated with a proprietary film of nano-sized cones. By deflecting errant light away from a camera’s detector, Canon claimed, the cones effectively eliminated the effects of scattering. Photographers could now get crisp, true-to-life images—no more ghosts or flares.
In a snowy parking lot filled with amateur stargazers, they attached the lens to a camera, mounted it on a tripod, and trained the diminutive telescope on a spiral galaxy known as M51. First observed in the late 1700s, M51 has been intensely studied and photographed for centuries. But after a two-hour exposure, Canon’s lens captured a sight that scientists had only gleaned hints of before: Extending far beyond M51’s bright central spiral was a distinct halo of diffuse matter. “We quickly realized that the lens really was as outstanding as we had hoped,” van Dokkum says.
Everything is going extremely well. There are no complaints.
I haven't heard anything about it in a couple of years.
Did the civil servant tasked with acting on it die of leukemia due to Wifi irradiation?
I always make time for Ballard!
Depends on what sort of technology is availiabe.
Physics indicates strongly that we should stop being juvenile and there are no magic solutions. Very much sub-c, acceleration means having reaction mass and the best you can do getting energy is total conversion of matter (there may be better ways to do that than having antimatter at hand).
Engineering all of that is out there. We barely manage to keep a nuclear submarine running with large maintenance bases conveniently not far away.
Economics... uh, oh!
I would like to note that the idea of constant 1G acceleration is a bit stupid as you would need vastly oversized motors to accelerate all that fuel mass at trip's start, whereas a trip's end you are down to a few tons so very much smaller motors would suffice. Better choose constant thrust for engineering reasons.
> Assume we don't have gravity generators yet
The only way to "generate gravity" is to pack a shitload of mass~energy into a small volume (because gravity and shitloads of stuff are essentially two sides of the same coin). Smells strongly like "no gravity generator in this universe", sorry!
As for the res,t according to
1G to Proxima with a perfect fusion motor (0.008 kg/m² fuel conversion) to put 25 tons into Proxima at rest (i.e. not zip through) will have you reach speed 0.95c at midpoint, will be 42 month ship time and will cost you 117'916 tons of fuel at start (this is the mass of one Israeli apple crop export).
You mean interplanetary, right?
Some of us SAW IT IN-THEATRE!
Have a gander at the animation of the Voyager 2 Saturn flyby using top-end graphics code and hardware. Not sure this is the one called "Voyager 2 - Blinn et al." presented at Siggraph '79, as accoording to Jim Blinn's page, there was a presentation at Siggraph '82. Time entropizes memories...
Instead of Brian Eno, the applicable music shoudl either be Lux Aeterna or the Jerry Goldsmith's intro to Alien, not sure which.
I have to say ... I haven't read it myself. But I remember a "Computer Recreations" article Scientific American by Dewdney discussing the failings of the perceptron. The idea of wanting to build a "box that lights a little light if you point it at a cat" just blew my mind.
(Update: It grabbed a copy from the SciAm store for a few dollars. This was a special issue on "Computer Software" and it has articles by Alan Kay, Niklaus Wirth, Lawrence Tesler, Peter Denning & Robert Brown, Terry Winograd, Andries van Dam, Michael lesk, Alfred Spector, Stephen Wolfram, Douglas Lenat. Damn!
It also discusses "inherently safe nuclear reactors", we are still not there. And is ad-laden to the point of unreadability ...)
Anyone who has lived through the "Red Terror" scares of the 80s (some of which are likely to have been entirely manufactured by NATO wingnuts) knows this is just the same old, same old.
He's not "my" candidate (anyway too old to care all that much, I noticed myself starting to dream of sitting on my front porch with a dog and a beer reserve), but you have to give him his dues. Making the press panic and the establishment candidates whore even more loudly than usual is a sight to behold. It is also telling. Telling that we are entering the final sprint and the system is now making more noises than a submarine at implosion depth.
The coda to every article written by the presstitutes exalting Hillary’s “heroic” tax disclosure asserts that, “By not releasing [his taxes] during the campaign, [Trump] is breaking with a 40-year bipartisan tradition of transparency expected of presidential nominees,” and that “there is nothing to prevent Trump from doing the same during an audit.”
Oh yes there is.
Clinton will never be perp-walked for flouting state secrecy laws, much less audited, or, conversely, criminalized by the IRS in the course of an audit. Were he merely to be accused of tax violations; Mr. Trump is certain to be destroyed by both political factions.
“When the people fear their government, there is tyranny; when the government fears the people, there is liberty,” forewarned Thomas Jefferson. When it comes to the IRS, Jefferson’s bar has been met. Trump needs to be very afraid.
P.S. ...I don't know the story about "The Clinton Foundation" (all comers welcome, favors repaid later, pay now because we will not accept your donation after the election) and the "The Clinton Family Foundation" (some othe rfoundation, as it seems), but these seem murky at best.
Anyway, getting off-topic, here, har har!
We should utilise the brightest talent of the world’s creative industries to counter terrorist propaganda with even more sophisticated anti-radicalising material. In the face of this new threat, we need a terrestrial star wars.
What kind of utter collectible moron says this kind of shit?
The Darth Vaderesque collection of even greater collectible morons in nominal charge on our side should give anyone with even a passing knowledge of history since at least "Darth Clinton" pause (soon with a neoconnish reboot in "Clinton II: Darth Harder", electible again because of the "female+liberal=caring" meme complex)
It's like when computer programmers produce some egregious piece of rubbish instead of a usable program
Not at all. When someone suddenly decides to write a program in INTERCAL, this will be readily apparent and a robust bollocking will hopefully ensue.
Spreadsheets in general (and the horrific Excel in particular) are the equivalent of INTERCAL for the business user. This is NOT readily apparent because they hide their in-built awfulness behind nice graphics, bells and whistles, tradition and the mindest that "there is nothing else". An acceptable idea back in the seventies, after Microsoft grabbed the market and added its "special user-friendly sauce" on top, they are now used way beyond what they should be used for.
Time to rethink this.
Is that Scumbag Steve's hat?
1) How often did the shell move from /usr/bin/bash and /bin/bash lately?
2) Code "conservatively" is actually an alias "not using features that make shell scripting less horribad". Are you still coding in original Perl? Why suffer needlessly for a couple of survivalist stuckists loudly proclaiming their insanity on the interwupps who insist on "original sh code" and who are unlikely to ever encounter your script in any case? It's rank masochism. And you don't even get a woman traipsing all over you on the plus side.
That's the idea. You want to leave the user the possibiity to soft-replace an executable using PATH if he is in the mood of pretending to know what he's doing.
Except for the shebang line, where you want to (actually, must) use #!/bin/bash or something (some people prepend "#!/usr/bin/env bash" which completely bonkers in a pretend-more-flexible-than-you way.
After a while the RFC will be forgotten and people will accept the MS versions of wget and curl as the defacto ones
What kind of people are those?
You know, they kept shipping a bad implementation of something that looks like a crippled command-line shell for 20+ years ...
"Seeking shelter in foreign lands" is not illegal.
It is not even immoral unless the assumption is that The State (or at least one of them ,if not several) owns your goods, your work and your arse. I don't think anybody signed up for this.
But the can kicking is now nearing the level of "better start a new World War rapidos now, before things get dicey in here and the guillotine gets erected", not sure where this is going.
Well, nothing that can be fixed with a bit of hitlerization followed by regime change, really.
(I don't think the EUC can unilaterally demand the monies without ECJ having a say... )
Thumb it down, Hillary voters. Are your ready for Madame Nuland at the head of the State Department doing her pivots wherever they are needed?
Corbyn's job is to just get the legislation passed, that's why he's a MP and not an engineer.
Not the same at all.
An engineer has to go up against reality.
An MP has to go up against the public and his peers using manufactured reality.
Stuck in a short train at Paddington at rush hour, waiting and waiting, people packing in and packing in, waiting and waiting...and dripping inside one's shirt...
Dark, satanic trains of the monopolistic capitalists. They are probably even transporting children in there.
If only there were some germanic communistic discontent with eschatological tendencies, scant knowledge of economics but who had studied that totally tripping absolutistic-monarchy-selling court philosopher Hegel. He could write a multi-volume book about these terrible conditions which could then be distributed via amazon.
That was back before the War on Durror (that's when I read the last IEEE Micro, after that I had to change my interests)
Get one for USD 94 here now:
They matter a lot if you're doing VR. Sloppy latency on scene calculations is a good way of inducing motion sickness. Given that everyone is getting into VR these days this might end up being of concern.
I don't understand this at all. VR and we are talking sub-microsecond realtime arrival times ... ON THE FSCKING CPU (yes, the CPU, not the graphgics pipeline)
Not going slightly overboard here? And I mean hanging on a 15 meter outrigger slightly overboard?
Whether CISC or RISC (a useless distinction nowadays, how about simpy "ISC"), there needs to be instruction pipelines. Otherwise how are you going to keep the various elements of the chip busy. Indeed, pipelines were just on RISCs in the first place to be able to issue an instruction at every clock cycle: RISC pipeline.
OTOH, this pipeline seems very deep. Recovering from a bad branch (i.e. emptying the pipeline, then refilling it) will take a few cycles.
Well, it would probably take a few hours to study the design in detail. Not my area now..
It does mean that this is useless for hard real-time applications. Branch execution time is now impossible to predict.
Well, "hard real-time" is still in the ms range, right, a few orders of magnitude slower? I don't think this is going to matter.
"Your Exynos only makes my penis harder!"
Seriously, I would not have considered a neural network used in branch prediction ... but in retrospect why the hell not?
OTOH, what are the features that enter into the (clearly supervised) learning phase, when is the learning over when is the network reset (likely not whenever another process gets schedule..)?
Precrime is now a thing.
A commentard called Naughtyhorse demands it!
$5 cups of coffee, that's real money, as opposed to giving away cloud storage space which is virtual money
Uh, venerable ancient ... you know ... about that US dollar....
The current version of Bing Rewards (sometimes) distinguishes between PC and mobile searches; currently users can earn 15 credits on the PC and 10 on mobile (regardless of device or OS used). That said it would be nice if Microsoft gave extra credits to those of us who do use W10 Mobile.
Thank you, Cortana!
Please tell me more about Windows 10 mobile.
That FOXACID manual is pretty hilarious.
Hack technician instructions ... I like it ... although the english style is not the best it's more lively than MS prose. And NSA is using ClearCase, it seems.
I think I will use this as an example to demonstrate technical writing at our place.
The Intercept forgot to [redact] an example IP 203.99.XX.XX, somewhere in Pakistan...
ALL the fucking summers since 2001 have been ugly, and there isn't even anyone who wants to actively democratize, liberate, genocidate, extraordinarily rendition, gazaify, ukrainimate or shock-and-awe me (not to mention slap me with surveillance order, ASBO, terror writ, sexual deviance order, looking-cross-at-hallowed-politican oder or what-have-you). As far as I know.
Eh? Who killed Fusilier Lee Rigby? Who blew up three underground trains and a bus?
Yes. Some people mistake an itch for cancer.
> This is how we won World War 1
I think that whatever was left of the British Empire disagrees that Britain won WW1 in any form or shape.
"Democracy never lasts long. It soon wastes, exhausts and murders itself. There was never a democracy that did not commit suicide". John Adams, Letter, April 15, 1814
It's like accumulation of entropy. At the end, legal and executive cruft overwhelms the system and the amount of power in crabby hands at the end of brains that have neither the intelligence nor the mandate to wield it is so overwhelming that blood needs to be spilled.
Then the cycle starts again.
