There's one, worse problem. Compromised credentials can't be changed. Only revoked. So someone somehow acquired your retina scan... sorry, Your credentials as compromised have been revoked, you're fired, come back when you get new retinas.
I imagine the day an ASG shop owner has his van blown up for transporting load of weapons. Because the scanner couldn't display the orange tips of the barrels.
I believe if much faster travel is invented during the flight time, a ship will be sent to pick up all the travellers and bring them to destination quickly...
There are 6 billion people. Do you really believe none could be found desperate/crazy/naive enough to want to go there?
btw, Centauri at 1g roundtrip would take 8 traveler's years and only ~12 earth years. Not quite as bad.
Still, with E=mc^2, to get 1kg to 2c equivalent you need to burn 2kg of matter in a nuclear fusion entirely. Plus whatever is needed to bring last of that fuel near the 2c... rocket fuel equations apply. That's why Proxima may be still within reach, further places - not quite.
Yes, these calculations include that. 4 light years to Proxima, top speed of 2c at halfway point, averaged speed 1c, 4 years to get there. It would be much shorter for a speedy fly-by, accelerating all the time.
Yes, but achieving precisely 1c would require infinite energy. We don't have that much. But if you double the energy, the perceived travel time will be reduced according to old Newtonian equations. So what if it's in fact the distance that got shortened, instead of speed being increased, ds/dt. You spent enough energy to travel at 2c according to Newton, and in your frame of reference you will get there in half the time as if you were traveling at 1c.
It may be moot for Earth people (50 light years is still 50 years of flight no matter how much energy they pump into the engines), but it means no need for hibernation/cryogenics for the travelers (who will perceive the 50 years as 7 years of ship time).
Yes, but the "nice 1g" (wow, artificial gravity problem solved!) gives us about 1 light year/year^2 acceleration. That is, gain/loss of 1c per year.
About 4 years to Proxima Centauri. 50 light years in mere 7 "subjective" years. 40 years of crew life would give 800 light years of travel distance. About 1000 parsecs in a lifetime.
Sure, we would still need engines that can provide sustained 1g. We're nowhere near that. We have rocket monstrosities that are barely survivable at 8g and more for minutes a time, and tiny farts of ~1N that can work for many years a time. Nothing in between. I believe a pure sustained fusion rocket might be capable of reaching Centauri stars, but that's still a long way away.
I think the threshold is not mass but origin/temperature. That is, a gas giant that is ablaze with thermonuclear fusion (or was in the past) is a star. Of course this is possible only above certain size/mass but there may be biggest gas giants slightly bigger than smallest stars.
Note, if we get an efficient engine that can keep accelerating (no "idle flight" period), it would be 60-70 years for earth-based observers, but much shorter for the crew. The speed limit of 1c is relevant to surrounding universe, but from the spaceship crew standpoints, the engine power - acceleration - speed - distance - travel time relation behaves in mostly newtonian way. If they expend power needed to travel at 10c according to newtonian mechanics, it will take (in their perception) 1/10 the time of travel at 1c to get there.

Nope. Not here.
Worse, if I press del, THEN enter, then the file gets opened, then I get a dialog "the file cannot be deleted because it is in use." But it's Windows that loves to do that particular trick.
Still, a server task slowed down by 50% will take 2x the time to finish, that's all. A GUI slower by 50% disrupts the user's workflow and will make the task 3-4x longer because the user wastes time elsewhere, performs unnecessary tasks waiting for the GUI to respond, overlooks appearing reply and reacts much slower...
Think of a network that runs at half the speed vs one with 50% packet loss.
OP is not joking. I'm using Ubuntu on eee900 netbook, and I can go make a coffee if I copy a 700MB movie from SD to internal storage. Lotsa RAM is not an option, and the system is default install of one partition for everything. It's pretty obvious if you have some overkill hardware the performance drop won't be nearly enough to affect user experience. No, "Buy More RAM" is what I'd expect from a Microsoft support to hear... I choose Linux primarily because of abysmal Windows performance on that netbook.
I thought copyright lasts some hundred years or so after death of last of creators, so Stonehenge's copyright should have expired about 4000 years ago. Which/whose intellectual property is being protected now?...or is it just that Stonehenge is a modern-made ruse, and the copyright is still valid?
Easy to spoof by implementing a flash memory emulation in a microcontroller. A chip that will behave like a flash chip, but in fact provides an extra abstraction layer and simulates faulty areas. Just like HDD controller that remaps faulty sectors to free area at the end of the disk, so from PC viewpoint the disk is fault-free and continuous, doing a similar device (which on top of remapping bad sectors, simulates ones where ones are not present, and makes them look precisely as expected) for flash seems quite easy.

Finally they will be able to computerize the national census procedures.

Of course then they could arrest you and put you in jail for refusing to follow the officer's orders, but that still sounds better than getting shot.

4chan is fundamentally Chaotic. Being consistently evil is far too... consistent for them.
So from time to time they pull out a stunt like making an awesome birthsday party for a WWII veteran.
Despite being a rather nasty artificial intelligence, Pinocchio never got anywhere close to starting a global thermonuclear war.
I disagree. I think these are all after-effects of radiation.

It can print using 5 kinds of blocks.
It's still not nearly enough, esp. that these must be BLOCKS (not gears/axles/etc).

Maybe not all of them are ill-meaning to freedom. But it seems these well-meaning are a minority.
