The scales you're talking about with interstellar travel are almost humanly unimaginable. The fastest probe we've ever launched would take over 100,000 years to reach even the closest solar system
Eh who cares. The proper model isn't a moon landing visit and return stunt but more like the national highway and railway network. It would take 100 years for me to visit every road in the US road network but I really don't care, as long as I can travel around my local area. So the proper solution is to take 10 million years to set up 10 million space stations each about a year apart. Much like the original ancient silk road, no one would ever travel the length of it, but you'd live along it and adsorb the benefits of it.
Its like arguing its stupid for boats and sea travel to exist because no human being or individual boat could possibly last long enough to sail every route on the map or visit every port... "eh". None the less, sailing is fun.
The historic part is its release day. Kind of like that other/. story where gathering 14 million or 13 million or whatever iphone UDIDs into a big pile wasn't the story, the story was releasing them for anyone to look at and download and mess with.
boring, smelly chemical fuels are simply not an option, but a heavy, electric beast is.
Fundamentally a battery basically is a boring smelly chemical fuel, its just in a can and hopefully doesn't make much smoke while it releases its chemical energy. There are some interesting thermodynamic issues with chem fuels and temperatures which can sometimes make a battery reaction more efficient (why the shuttle uses fuel cells instead of a little internal combustion engine to generate electricity, etc). Another reason chem propellants suck is the projectile can never, ever travel faster than the speed of sound of the column of compressed high pressure gas in the barrel, but at least in theory theres no reason an infinitely complicated coil gun couldn't launch stuff at any ridiculous speed.
That "speed of sound in the barrel" is interesting to think about... the pressure is so high in the barrel that the speed of sound might be 2 or 3 times, maybe even more, than the speed of sound in sea level air.
The battery size reflects the "clip" size. You'll be lucky if your battery size/weight is much smaller than the ammo it flings for a bunch of basic chemistry reasons. A battery the size of a truck trailer would be able to fling a volume/weight of ammo about the size of a truck trailer, either all at once or more likely eventually. In other words the energy density of chemical batteries is never going to be a whole heck of a lot better (like orders of magnitude, not the smallest decimal point) than the energy density of smokeless powder. Hence the intense interest in hypersonic projectiles. I suppose if you had a nuclear aircraft carrier or nuclear powered submarine to power it, then...
The velocity reflects the weight and number of the coils. Something that is pretty wimpy compared to a slingshot is about the most a human can handle. If you insist on hypersonic velocities its going to be immensely huge and probably quite inefficient as a tradeoff making the whole weapon system fairly useless.
Your budget reflects the total projectile energy via capacitor bank size. Something light enough you can pick up and an individual might be able to afford makes for the worlds wimpiest pellet gun, not much more than airsoft really. If you insist on blowing up a tank, you'll need a truck trailer full of capacitors costing about as much as a house. Capacitors are a really awful way to store energy, but the only way to release the energy quick enough for hypersonic power. If you get serious, internal resistance and crushing magnetic forces and strange resonant effects become a big problem (no longer able to treat the cap as the simple AC/DC electronics 101 simplification of a perfect device anymore)
Usually the limiter for the home builder is triggering followed by power supplies. Whats most likely to stop you is finding a big and bad enough set of SCRs or whatever to handle triggering or if you try mechanical like this guy you end up accidentally building a arc welder, second your average noob is mystified at how to generate more than a couple hundred volts without spending lots of money or getting killed or blowing up the trigger system. If they succeed at that, the next limiter is usually the spectacular cost of high voltage low resistance high capacity capacitors... any 1 or 2 of the 3 isn't going to do, and maxing out all 3 is going to be very expensive. Assuming you pull that off, coils are pretty simple, as are batteries.
If you're still actively reproducing over age 70 let me give you a high five.
Now a magic carpet to prevent pregnant chicks from falling, or little kids before reproducing age, that would be natural selection. This is just being humane.
In my limited experience watching relatives fall and die soon after (well, not in person, but hearing about it) its not the fall that's the problem, but the heart attack that lead to the pain that led to the fall, or the stroke that led to the fall, or the kidney/liver failure that led to mass confusion that led to the fall... yes these relatives of mine technically did fall and then die, but the "real problem" was what made them fall, not the fall that made them die soon after. So I'm not entirely sure than locking old people in a kids inflatable "bouncy castle" is much help.
Also it seems a stereotype at the hospital/old folks home/hospice that the last thing people do before being permanently bedridden is fall, then they're like chained down or ordered never to stand again, which coincidentally happens pretty late in their decline, so naturally they continue to decline and die like the next week, because apparently standing is not terribly difficult so its one of the last things to go. Come to think of it, it is pretty easy, since its one of the first things kids learn to do...
I'm just saying its not going to make anyone live longer or better, just means they'll get confined to bed rest and die soon after anyway. So its kind of a depressing invention. Kind of the opposite of "let me die with my boots on" type of thing.
God forbid I have someone come over for dinner and they're unable to login to my infrastructure switches and peruse the configs!
In years past I've had repeated experiences with Cisco TAC along the lines of "I donno we've never seen anything like that before, mind if we log in and take a look?"
This is for stuff that takes more than "show tech" or where "show tech" looks so weird they need more data.
Needless to say this was at an ISP with a hardware budget best expressed in scientific notation, not home user with a $79 smart switch.
Its not as unlikely as you'd think.
The funny part is they always reboot and if that doesn't work swap hardware... its just a delaying tactic or to make the customer feel better, as far as I know.
and even intrinsically safe (i.e., won't make sparks that would ignite flammable gases) characteristics.
OK I'll bite. How does garrettcom do this? I mean at the ISO level 1 electrical/hardware characteristics? I'm guessing its a huge challenge to do PoE that cannot theoretically spark when you yank a current carrying cable out of a jack. Maybe physical lock holds the ethernet plug in and unlocking the plug powers down the PoE faster than you can yank the cable, or some ridiculous arrangement with constant current source and a SCR crowbar ckt if the voltage rises too high aka is arcing? Or they just don't sell PoE, which is probably the simplest solution? But aren't there some of the zillions of copper ethernet standards with what used to be called in the telecom world "simplex current" so even just being non-PoE won't help? Old fashioned FDDI would seem to be the simplest intrinsically safe solution.
TLDR: curious at a hardware/electrical/EE level how intrinsically safe PoE works.
I'm not familiar with the gear that has the "exploit" but I'm assuming its vlan capable, and none of my vlan capable switches have ever been accessible by anyone but the SNMP management console machine and the network admin's desk and a couple other "secure" locations. By design not as simple as plug into an ethernet jack in the conference room and telnet in...
If this hardware isn't vlan capable I'm not sure what they're thinking WRT the design. Probably some GD software patent on the concept of having a management VLAN. Although I know cisco and netgear switches both have this concept, so at least its widely licensed.
I do find it funny how Windows and Linux, were not as graceful from the 32bit conversion to 64bit like Apple and Sun Microsystems.
I think you might not know about the alpha linux port in the mid 90s. 64 bit native kernel is not much of an issue. How the distros handle multi-arch, now that has been recently exciting.
In the real world, the banking and trading system is monitored by people with the power to enforce, have long histories and memories of what can go wrong, and is generally policed by governments cooperating.
But the internet equivalent makes it sound like a bunch of shady, back alley people doing financial transactions outside of the normal system.
The mistake is thinking that because the "real" economy needs a "bank" or a "exchange" then a virtual one just naturally of course without thinking needs to replicate the real world.
Kind of like shopping at Barnes and Noble means I wait in line and the teenage cashier takes forever to give me change while she checks her SMS and FB on her smartphone, therefore "naturally" amazon should try to replicate those parts of the experience using "3d virtual reality" or something idiotic like that.
I'm not seeing the point of keeping $$$$$$ worth of BTC in some goofballs BTC "psuedo-exchange" or "psuedo-bank". And I'm not some noob talking out of ignorance, I mined BTC in software back when the difficulty level was a small two digit number (aka a very long time ago in BTC land).
These assets can only appreciate in value after the economy collapses
Toilet paper, aka the alpha plan. You can survive without ammo, without beans (I hate beans) but one way or another you're buying TP. And due to inflation prices only go up. So store as much guaranteed consumables as physically possible purchased as early as possible.
Even if you buy gold at the ridiculously inflated prices and get gold in your hands, someone's going to find out you have $50000 worth of gold under your mattresses and rob your house.
Unless its in the $9/month safe deposit box at the bank, or you bought GLD ETF aka "paper gold" which has all kinds of annoying income tax implications BTW.
Both sides provided carefully worded political babble. There is no "real" to summarize. Like trying to summarize two different religious books neither of which you believe in.
Another option, AntiSec hacked someone pretending to be an FBI agent. I have run across people like this, who are trying to con you or just getting their jollies.
Infinitely more likely is they hacked a civilian employee or contractor of the FBI who merely happened to have the named agent log into the laptop once, or maybe the named agent worked closely with the civilian. That way the FBI can truthfully deny, yes, indeed, the FBI has no UDIDs...
They also VERY SPECIFICALLY stated that no "FBI laptop was compromised". This is very important. The MIB might have copied the file onto his personal laptop, or it was technically a FBI leased laptop instead of being a FBI owned laptop, or in some sharing arrangement the laptop was technically owned by the treasury dept as some kind of expense sharing arrangement, or the FBI gets this data (from apple?) by having apple mail a apple owned laptop full of data to the FBI, or its part of a cooperative cross departmental arrangement where the NSA provides the hardware, the FBI provides the men on the ground to lean on apple to release the data, and the DSA provides physical security/office space, so technically in the narrowest possible definition yes that is not a "FBI" laptop.
It would be nice to think that one day we'll reach a technological level that allows us to overtake Voyager 1. I'm not that hopeful though. I think that the head start Voyager 1 has means that it always will be more remote from Earth than anything else constructed here. Excluding Pioneer 10, that is.
There's some planetary alignment issues such that it would be really hard to catch Voyager. The New Horizons probe, despite being something like the fastest probe ever launched, is moving considerably slower because it had unfavorable gravitational assists, something like 10% slower than voyager. The planets have to line up, unless you do something ridiculous like launch a tennis ball a Saturn-V
Both are practically slow crawling compared to the Helios probes from the late 70s/early 80s which were moving something like 6 times the speed, although toward the sun not away. The Helios probes are still the fastest controllable "things" produced by mankind. The "controllable" is necessary because there's a famous nuke bomb test film where analysis of adjacent frames shows a manhole cover moving about about 0.1c... at least for a little while.
Nobody mentioned Rule 34 by Stross and the product the toymaker was making/selling?
We're going to have laws long before we have rights, and the laws are going to be things like banning virtual / simulated CP. Long after its all "ruled" and "regulated" and "lawed" up, maybe we'll begin to debate rights.
