You can't prevent the problem by throwing work at them. This may be effective initially, but eventually they'll screw actual work and focus on other items.
You don't need to be an astronaut to understand this - everybody gets tired if they do their homework all day, or if they type a book all day long, etc. Even doing nothing all day long can also have consequences.
I think you put too much emphasis on the 'let them work' approach. Besides, some missions will last more than several years, so your friend's experience does not apply to this. My conclusion is that it needs to be solved by looking at the problem from another point of view; we don't need workarounds, we need solutions.
I think that's severely oversimplifying, because rewriting the system to take only one system call would certainly result in more bugs, no?
Exactly. Also, it is always emphasized that a program should be split into re-usable chunks (functions); which is much better than writing the whole thing in your main-function (difficult to reuse, a lot of redundancy, etc)
So, my question is, why does 'a graph with less vertices' mean 'a better system'?
They've switched to MSI installers; I installed 0.9.0 at some point in the past and deleted the installer. Now I want to update to the latest 0.9.3 and it won't install unless I point it to the old installer.
I know I can deal with this by downloading the old one, but this is counter intuitive and it doesn't make sense.
I agree with you, I think that the whole Siberia thing is just made up by the press, to make the story more dramatic. I am surprised they didn't say the guy would be fed to bears wearing shapka-ushankas and dancing and singing kalinka somewhere in the heart of the Taiga, where the nearest check-point of civilization is X thousand km away, where there is so much mud that even the most high-tech valenkis won't help.
Maybe they will force him to re-build the BAM as a punishment? Oh, the media these days...
Yes, but it uses CBC mode, which means that block N+1 is obtained by XOR'ing some intermediate data with block N, thus a change in the Nth block will propagate to N+1, N+2, etc. Now TrueCrypt uses a different mode, which is more secure, but the principle is the same.
Anyway, regardless of that, the problem is still handled, and a bit-flip will only affect the current sector of the storage device, but not all the ones that follow it. I don't know the low-level details though.
The tool I mentioned can store the data on a USB flash disk, all you need is a USB port; at least half of the problem is fixed.
All the email clients on my computers are configured to leave the messages on the server for a few days. Once I receive a digitally signed email from a friend, that email will be received by all the computers, therefore the credentials of the other party are available.
And if that doesn't help - the CA should make everyone's data available in a public directory.
E.g. here at home I cannot verify any signatures that I can verify on the computer at my work, because I do not have an up to date certificate store.
You can use a cryptographic provider that can store the certificates and the keys on some sort of media (ex: token, smart card or USB drive). When there is a need to use the certificate, the application will ask you to connect your smart card (or whatever it is that you chose to use).
having to log on twice (once to the OS, then again for Citrix)
You could either use a single sign-on solution, or use an alternative approach to automate authentication and to secure the mechanism of credential storage (use smart cards or tokens).
I happen to live in an ex-Soviet country, and one thing is known for sure - there is not one large company (or any other entity, like a university or an organization) that uses a.su domain to emphasize its presence on the entire ex-Soviet territory. A company with a leader who is not insane will most likely avoid having a.su site because it will associate their business with communism, and communism is a bad thing (tm).
I don't know where you are from, but I'm pretty sure you won't be able to come up with a case in which a.su site is an instance of your example. (I wouldn't bet my life on it though)
In fact, I only know several.su sites, all of them use.su for the "coolness factor" (which many don't find cool at all), the sites are loaded with ads and useless info.
I am not aware of a single person who will suffer if these sites will disappear. Perhaps this will happen to the owners of those domains, they'll feel ripped off because they paid so much for such a "cool" domain, and now it's gone. Another possibility is that these sites are the expression of the feelings of those who still want the Soviet Union to form again (it is a form of nostalgia not everyone can understand; the SU had some nice 'features' too).
Why so? It could be the other way around - colonizing space brings the raw materials and the experience needed to stimulate self-evolution and eventually reach singularity.
Our current level of technological development does not allow us to estimate accurately which of these objectives (singularity vs space colonization) is more complex.
Hmm, but the thing is that it's not a fact that they are looking for life forms. The primary objective could be different - ex. resources, or a planet they could inhabit.
Taking into account the fact that our society is pretty materialistic, I doubt that our probes will be looking for life. Most certainly, they'll be looking for useful raw material (and perhaps for life, among other things.. but definitely not the primary target).
Check out the movie called 'The final cut', it tells of a technology similar to the one you described (though it employs no encryption and is used for a different purpose).
I am afraid that this won't do, since it will be possible that people will be abducted and then forced to give up their video-logs, just like they are now forced to give up their passwords.
THey might come up with a law that prohibits you from NOT sharing your log when you do have something to show (ex: somebody saw that you saw something happen, they say that you saw that - therefore you MUST cooperate).
Then there's plenty of space for a backdoor in there, so the government could use the logs without your consent.
Finally, if all the public cameras were replaced with these individual cameras, it would mean that justice is always in the hands of the 'witnesses'. Some of them may be afraid to testify; some obscure/distant places that don't have many visitors will become more likely to 'host' a crime, etc.
I think the problem with your example is that the model you propose is human-centric. From my perspective, the value of the bill is $10, regardless of us knowing about it or not (because the truth exists even if you don't believe in it, or don't care about it).
Here is another one: - imagine that there is a rock lying on the ground, - let m1 be the mass of the rock after it was seen by one person - let m be the mass of the rock when it is not seen by anybody
is m different from m1?
Where I'm getting at, is that the universal laws of physics 'claim' that $10 bill (even though it only has a meaning for us, while for the universe it's just a set of particles)
There is another approach - take off the cover which protects the battery. Underneath the battery, you will see how two wires are connected. If the color of the wires is green, then you're bugged. Otherwise, if the wires are red - it's a bomb.
Other colors are not defined by the standards, so if your phone has wires which are not green, nor red - you have a counterfeit phone.
There is a question I was thinking of, perhaps you can shed some light on the subject... It is known that time is a relative thing, when objects move at different speeds, time 'flows' differently for each of them.
How do the dating methods deal with this? I mean, doesn't the obtained result simply state how old an object is if it 'spent its entire life' in an environment such as ours (is this a reasonable assumption?)?
I'd kill kittens if they told me that my users were going to just plug in a smartcard to get access.
Smart cards can be PIN-protected. N invalid PINs in a row, and the card is blocked (N is usually three, but it depends on the case). So smart cards are pretty secure, since they make brute-forcing NOT an option.
Besides the issues pointed out by others, there is another one - what if my company offers more than one type of product? I would be forced to register a zillion domains.
Hmm, how about re-phrasing that to something like "The Internet is a network which relies on nodes that forward information to other nodes, anybody who controls such a node may examine the information being forwarded".
This should explain someone that it's a bad idea to share private information on the internet.
Another thing - you (the parent) are a person who administrates one of those nodes, hence you tell them indirectly that you too *may* have access to the information.

NIST maintains a list of those who passed the tests successfuly, and were certified to use AES in their products.
So, besides making sure that all the things mentioned by the parent were done right, check out whether the algorithm itself was properly implemented.
Hmm... if after the game they would show you what your partner's labels for each image were, then yes, it would help you see how others think; but that's not the case.
I am a non-native English speaker, but I do speak 3 languages [+2 in beta]... If I missed something, tell me how exactly this thing has helped you understand how others think.
P.S. it would be great if the partner chould be chosen. It could be used in companies or other places where teamwork is important - once you establish which person from the group is more compatible with yourself, the two of you can work together more often and engage into various projects.
I too played with Kai's Power Tools a long time ago, it looked pretty, and I was impressed. However, those days I never did any serious work, I just played with the program's GUI widgets and saw how that influenced the final picture. Nowadays I wouldn't pay attention to this program, because I need to get things done, rather than play with an application.
Such a GUI may be a good thing when the user is interacting with the program for the first time. But when you need to seriously do something, eye-candy won't increase productivity.
For the past two days I've been reading a lot of info about GUI design guidelines, and here's a doc by Joel Spolsky; the funny thing is that he uses Kai's tool as an example of how not to do things
Note that it was pointed out earlier that OS!=GUI, but still, a GUI plays a major role in the user's perception of the OS, therefore this sub-discussion we're having is on topic.
Hmm, but if I know that the camera is pointed to the road, I can bias your randomizer by driving the same car on the same path, at regular intervals; or by placing an object near the camera (taking up most of the picture, thus minimizing the impact of the truly random objects in the picture).
I've recently read a set of reviews about Pocket PCs, and several different authors have emphasized that those that run at 640x480 have a shorter battery life. I haven't tested this myself.
On the other hand, I've interacted with many Palm OS devices thruout the years, and indeed I can say that screen resolution didn't have an impact on battery life. The factors that _are_ behind that are the wireless interfaces.
