This is definitely not the case where I live. My ISP gives a new ip on each connect, often a different subnet, and the reverse-dns adresses are tied to the IP and change with them. Any DSL provider I know does the same thing.
Several even force a disconnect after 24 hours, others have longer periods, but changing your ip is as simple as setting your modem to disconnect on idle.
now I might missunderstand that rfc, but it seems totally useless.
You can only get a different address within the subnet your provider assigns to you, so companies will simply maintain a table of which ISPs use which size of subnet, and ignore the corresponding variable part of the address.
So, certain SSDs have a firmware "garbage collection" that analyzes the file system and marks blocks that are unused, even when the OS does not issue any trim commands.
While perhaps a nightmare for forensics, this seems like a particularly useful thing for normal use. Presumably it only works for NTFS, but it would be very useful for windows xp, which I assume does not fully support TRIM.
How can I tell which ssd supports this option? is there a marketing name for it?
I do not have a smartphone myself, but one of the first apps I would install would be some sort of fake data sandbox for apps.
I have seen the install screen for android apps briefly: they show what sort of permissions an app needs: access to GPS, address book, outgoing sms, etc; but the only options seemed to be "grant that access" or "do not install"
So simply add a checkbox that allows me to supply fake GPS data, fake "no connection" signal, fake empty address book for apps that I do not want to access these parts, but want them to run regardeless.
Is that impossible ar particularily hard to program?
Whereas my alarm clock, even with the snooze button, will continue to go off every 9 minutes at least. I've used this to my advantage though - since I know It usually takes me hitting the snooze button 5 times before getting out of bed, I just set my alarm 45 minutes early. It doesn't make a whole lot of sense, in actuallity I get less sleep this way, but it works for me.
I had similar problems. 9 Minutes of snooze is far too long, I was back in deep sleep by then. 5 minutes work much better. Now I have to hit snooze not quite as often as before, and even if I do, the time wasted is much shorter. The disadvantage of most alarm clocks is however that you cannot change he snooze length, whereas my phone can.
Is there a way to disable java across all browsers, but keep it installed for other software like openoffice? I.e. block all applet functionality, but still allow local java code to run?
That would make maintaining friend's pcs a lot easier. They never update on time, and when they do, I always have to remove a new bundled browser toolbar again.
"because you need to ask the user if they really want to shut down and if unsaved documents should be saved"
This is one of the most annoying things about computers. If I want to shut it down, shut it down! It is to late for questions, I probably already left after I issued the shutdown command.
Any question about unsaved documents can be asked the next time I start the program, just save them in a temporary location in the meantime.
Standby and hibernate have somewhat mitigated this problem, but for multi-user systems there is still no practical solution.
- Shred/chop/smash the material. - Run the small pieces through a rinse to take care of e.g. unrinsed bottles. - Vibrate or centrifuge the material so the it's sorted by mass. - Skim off the different types of plastic (or metal, etc.) in layers.
different grain size would be a big problem. Size and shape of the pieces would probably influence their position in the layers much more than the small differences in their specific weight. The pieces would need to have uniform shape and size for this to work well.
Unlike fingerprints, genetik markers from related people are simmilar. Therefore you can deduce who is related to whom. I am not sure to which degree, but with enough genetik markers, you could probably deduce even distant realtionships. If someone knows about a genetik predisposition in one of your relatives, they can draw conclusions about your genetik predispositions. (Or they can just just assume that a person from a family of criminals/terrorists will likely be criminal/terrorist as well)
Furthermore I highly doubt the original dna probes will be destroyed. Genetik markers are an active field of research, so it would make sense to store all dna in liquid nitrogen to be able to reanalyze it later. Due to the small size of a probe, this would be quite cheap.
The process should be slower if the masses are farther apart, but I do not know anything that could prevent it. Having more masses should speed the process up.
The smaller black holes might evaporate before they actually collide, but cosmic background radiation probably more than makes up for any loss due to hawking radiation. Of course, with the expansion of the universe, the background temperature lowers, so they might evaporate after all.
Still, in the end two gravitational bound black holes should either merge, or disappear due to evaporation.
Quite likely pretty much all galaxies will be "a galaxy of black holes" at some point, simply because virtually everything else will decay in the meantime (and long before black holes themselves will decay). Some models even have the possibility that whole Universe will turn into a singularity (though not really of the same kind as a black hole)
As for "giant one with an event Horizon as big as a galaxy", you're unlikely to find enough mass in one place for something like that to form (nevermind the unlikeness of all that mass collapsing into a black hole)
If we are talking long term, should a galaxy of black holes not evenentually turn into one big black hole?
IIRC orbiting masses should always radiate a small amount of gravitational waves according to general relativity. This energy is deducted from their kinetik energy. So a galaxy, or any gravitational bound cluster of galaxies, should eventually end up as one big black hole. Unless something like the big rip separates them first.
With glasses, you can make the world move relative to the rim by moving your head, and your brain uses this to help filter out the rim. Do PC window managers have an analogous feature to nudge all windows?
More importantly, with glas frames and car frames in your vision, you can make a minute movement with your head to see what is behind them, and your subconscious does that for you. With a computer screen this reflex does not work.
The mythbuster episodes about speed cameras are horribly boring, since you know from the start that if they were to find something that actually works and is feasible, they would not be allowed to air it.
Toddlers have racial biases. Even babies just a few months old will prefer to look at a picture of someone with the same skin color as them. It's built into the way our brain works.
Is that actually nature or nurture? If an orphan baby is adopted by parents from a different race, and is surrounded by people of that race, how would he even know what his "own" race is? As long as you keep him away from mirrors, he would not even be able to tell that his face looks different, and althought he could see that he has a different skin color than everyone else, as a toddler he would also have different size and proportions, a far greater difference.
The theoretical macroscopic properties of antimatter are the same as matter. Interaction with light, gravity, the fundamental forces, entropy would be all the same.
If you had a world made of anti matter, everything should work the same.
Well, almost. There is a slight asymmetry between normal matter and antimatter in relation to the weak force, so you could at least tell the difference by carefull observation. Or these small differences might result in vast changes in the world.
I am having a hard time finding the original survey questions (probably for good reasons) Even so, this smells like bullshit.
The only (apparent) quote I could find: "Jeder vierte Deutsche (23 Prozent) würde sogar einen Computerchip im Körper tragen, wenn es ihm bestimmte Vorteile verschafft"
~ "every fourth German would even carry an "Computerchip"(e.g. an integrated circuit/microprocessor) in their body if that would result in certain advantages"
Like anyone would refuse to wear a pacemaker with a integrated circuit.
References to "for identification purposes" or "under their skin" appear to be made up.
However, a few decades of not using antibiotics at all and the bacteria around the world will again mostly be susceptible to the more common, low-risk ones. The mutations that make for antibiotic resistance have negative effects on bacteria's ability to reproduce... except in an environment with significant antibiotic use.
Immunity to antibiotics would diminish, but I imagine in many cases the neccessary genes would be only supressed or disabled, not completely removed. Plasmids integrated in an inactive part of the genome, point mutations in the promoters and stuff like that. If we started using antibiotics again, immunities might quickly return.

Could he have given them a random password, and then act dumbfounded when it does not work?
Maybe even accuse them of breaking his system?
It is hard to prove that the header of an encrypted disk has not been corrrupted.
Would that work with the current law? Has anyone already tried it?
So, what are the best ways to profit from this crisis?
Hoarding IP addresses is an obvious way, but that market seems pretty crowded already.

Except they did find and air one way: The changing plate system. Even more illegal than speeding though...
The only reason that worked was because they knew in advance the exact time the radar control would take a photo.

Has anyone tested this?
I guess the same way google, microsoft update or similar sites do it. Massive bandwith, redundant servers, a little black voodo.
