  1. Hmm... on Ask Slashdot: Could E-Mail ever Replace Snail Mail? · · Score: 2

    First of all, a major problem with email (just as with snail-mail) is that it is unreliable. You send an email out and in the general case you have no clue whether it reached its destination or some host on the way folded, spindled and mutilated it, and then discarded it. Some MUAs offer delivery receipts, but generally they require that you run the same mail client on both ends. We really need an RFC (maybe there is one?) for mail delivery receipts and have it implemented in all MUAs.

    As regards to authentication and encryption, this is a bigger issue. The general answer, I would say, would be: the general population will use authentication and encryption when it will be build into all mail tools, switched on by default, and work transparently. I am rather pessimistic about more than 1% of computer users doing something proactive to use encrypted email. And from personal experience I know that trying to communicate by encrypted email with people who don't understand either encryption or the need for it is a pain in the ass.

    Authentication (i.e. digital signatures) is a complicated topic with the key problem of correlating a digital signature with a real-world or an online identity. There are two major approaches -- one uses centralized certificate authorities that vouch for the key-identity correspondence, and another (PGP) uses what it calls a web of trust. Both have significant problems and are not in widespread use.

    I guess my answer is 'don't hold your breath'. Security is complicated by nature and people are generally unwilling to spend the time and effort to work it out and set it up. Another answer, which the /. community will like even less is that authentication and encryption will become widespread when they will become default settings in Microsoft Outlook [ducks, quickly pulling on his asbestos long johns...]

  2. Required reading on Suck on Linux Evolution · · Score: 3

    The Suck article should be required reading for Linux zealots. Not because it is completely right, correct, and reflects the absolute truth, but because it is focused, edgy, nasty, and says the dirty words without flinching. The guys at Suck have a point and they make it very well indeed. You may disagree with the article or parts of it (at least I do), but the issue is not going to go away. That's the same issue that has been repeatedly surfacing at Slashdot and subject of much discussion by a lot of very smart people -- Linux and the big bad commercial world out there.

    I'm not going to try to recap these discussions, but I think it's worth pointing out some quite trivial facts:

    RHAT is a public corporation. Its management has legal duty to maximize shareholder value by whatever legal means necessary. Historically, courts have given a lot of leeway to company management in deciding how to go about it, but on the other hand, management has been sued, sometimes successfully, for doing (or not doing) something useful for shareholders. Think about it: if they believe, e.g. that writing and selling proprietary extensions to Linux, will make the company more profitable, then the RedHat management has a duty to do this. I really would not be surprised to see an effective fork of Linux (on the same kernel base) into a "corporate" Linux, sold, say, by RedHat and Corel, and a "pure" Linux, distributed by e.g. Debian. It's not a good thing to happen, but welcome to the real world.

    So, yes, the transition from the academic/hobbyist/sysadmin world into the rat-eats-dog-eats-rat corporate world is dangerous and will probably affect Linux in some way and the Suck article pointed it out with a very-well-sharpened finger.

  4. Police abuses on Feds Want Access to Your Machine · · Score: 2

    You're implying that protections against police abuse rely upon the irretrievable hiding of information from the police.

    Yes, they do. That's not the only protection, and probably, not even a highly important one, but my capability to hide information from police puts a limit to police's power and so indirectly protects from the abuse of this power.

    I don't trust the police to do all the right things all the time. I do want some capability to personally control which information can be found without necessarily depending upon the wisdom of some judge. You are telling me to trust the system -- I don't want to trust the system.

    The illogic of this scenario is that a warranted search that turned up papers with the above information would in no way violate your rights

    I don't see anything illogical here. If a cop searches your house without a warrant and finds some cocaine, he violated your rights. If you go to a cop and hand him the same cocaine, your rights weren't violated. So what?

    Again, the 4th Amendment relies upon the court system, not individuals, to control police abuses.

    Yes, but to repeat myself,

    (1) Some assumptions on which the 4th was based have changed or are changing

    (2) Regardless of what the 4th relies on, I do want some personal protection against police abuses.

    Furthermore, you can argue 5th Amendment protections, regardless.

    What do you mean? If the cops have my data and my encryption key, they don't have to ask me anything, the 5th just never comes up.

    As I've said before, the potential for abuse of power (i.e. ignoring the need for a warrant) is another issue, entirely.

    No, not at all. If there were no potential for abuse, there would be no need for all the checks and balances, and for the 4th in general. It is exactly the balance of power between the individuals and the government, and the distrust of the government, that brought to life the Bill of Rights.

    Besides, I disagree with your examples. If I have encrypted data on my hard drive, it's currently very hard to get it. A single person is not likely to have the needed resources (TEMPEST surveillance, hardware keyboard sniffers, etc.) even if he resorts to illegal methods, and a small-scale corrupt system isn't likely to do much better, either.

  5. Re:Why is this bad? on Feds Want Access to Your Machine · · Score: 2

    The 4th Amendment's protection against illegal search and seizure does rely upon the "difficulty of conducting a search" or the efficiency of police operations. Rather, the entire rationale of the Amendment is the use of a warrant system for such protection.

    The framers assumed certain things about how the world operated and build a system of checks and balances based on these assumptions. If some of these assumptions become invalid, the checks and balances are likely to become unbalanced. Stepping for a second into the realm of science fiction, imagine that the police officers can effortlessly see what's happening at any time in any location. Wouldn't the 4th Amendment be different then?

    However, we're not talking about placing cameras in every home,

    Not yet. But the "slippery slope" argument is pretty convincing here. Witness all the govenrment efforts to mandate backdoors to all encryption -- this is very similar in spirit.

    We're talking about the police, with a warrant, entering a home

    No, you don't understand the difference. Let's say I have collected a large body of information on home-growing of pot and stored it on my hard drive. Suspecting that other people might not think that my motives are pure, I encrypt all this stuff, and, maybe use steganography, as well. Now if the cops come with a warrant, they have to deal with the encryption. They need a court order for me to surrender the key, I can claim Fifth Amendment, etc., etc. It becomes a prolonged legal battle, expensive for the cops to wage.

    However, in the case we are discussing now, the cops have installed a keyboard sniffer on my machine and so don't need a court order for my encryption key: they already have it. Major time- and effort-saving for cops happened, and I am screwed in worse way than with a 'normal' warrant.

    Again, as I posted elsewhere, I don't believe (as a lot of posters around here) that the main issue is with the warrant being sealed. That was done before, and while unpleasant it is understandable and perfectly legal. I think that the main problem is making the search-and-seizure so easy, fast and cheap, that the balance of power shifts and the protections we have look much more inadequate.

Your local cops physically cannot do 1000 searches every day. Electronically they can, and they will be tempted very much to do so.

Only later, if it turns out that the cops do need info from your hard drive (say, they are bored and want to check out your pr0n), then they can use the handy captured passwords to read all your safely encrypted stuff.

If you perceive the environment around you as safe (huge media role!), then you become more tolerant of the different ones, and vice versa.

    People become afraid and distrustful, especially of strangers (note that depending on the circumstances that might be the correct and rational thing to do) ->

    You are somewhat confused. Let's try to clear up some of terminology.

    "Utopian socialism": forerunner to Karl Marx from which he (Marx) borrowed a lot of ideas about the desirable form of society. Under utopian socialism everybody lives in the same conditions, labors for the general good, owns nothing, and generally behaves himself. This is basically a secular form of a monastic order. People nowadays tend not to know anything about utopian socialism and tend to be horrified when they learn the details, which are very unpleasant (as in death penalties for insubordination, prohibition on any unsanctioned sex, breeding of people for genetic traits, etc.). Campanella is a good example of an utopian socialist writer.

    "Marxism": an economic, social, and political philosophy, formulated by Karl Marx. Never implemented in reality. Economically it is based on common ownership of means of production (Marx was very vague as to who would actually run factories), socially -- on utopian socialism, and politically -- on violent revolution overthrowing existing governments worldwide, with the semi-anarchic global community without any governments to follow.

    "Communism": two meanings. Meaning one, the original one: a phase in the socio-economic history of manking that follows capitalism. Very rarely used nowadays. Meaning two, the common one: the political, economic, and social structures implemented in Russia in the beginning of the century, and later in Eastern Europe, China and some other countries. It mostly has been developed by Lenin, so sometimes the word "leninism" is used. I use "communism" in it's second meaning.

    By the way, the meaning of the expression "Workers of the world, unite!" is "unite, so that we together can overthrow all the governments in the world". It has nothing to do with population taking care of itself through cooperation.

    What most misinformed Americans (including myself up until about two or three months ago) believe the only form of communism is the supposed Russian atrocities, but this is false.

    First, I am not a misinformed American. Second, the Russian atrocities are not supposed but quite real. By the best estimates Stalin killed about 20 million people by artificially induced famines in the 20s, plus about 10 million perished in labor camps during Stalin's lifetime.

    Many countries are using some form of communism.

    Right now I can think of North Korea, maybe Cuba, but that's about it.

    In true communism, people give up their possessions voluntarily, to provide for a better life for others.

    I don't know what do you mean by "true communism". Karl Marx certainly didn't envision it this way. Some utopian socialist did, but see above re their views.

    It is only when these rules are enforced at penalty of death that communism becomes what most consider it to be.

    It so happened that these rules always were enforced at the penalty of death. Doesn't it tell you something?
