  1. TLDR;:As if SMTP were ever secure... on Clinton Regrets, But Defends, Use of Family Email Server · · Score: 1

    Smaller systems are intrinsically more focused, which implies better privacy.

    Let's not conflate privacy and security. Thats' not straightforward if we talk about such obscure concepts as group- or team- privacy. Anyway, it's obvious that sysadmins can access email contents, which we may call a privacy breach. When someone who was not appointed by the team or group does so, we call it a security breach. There are recipes to defend from the latter, not from the former.

    Of course, one can choose to be "transparent" and operate through a gmail account. I don't recommend it. On the opposite, I recommend every group or team run their own email servers if they can spare the effort to keep them secure. I'd vote Clinton just for doing so if I were American.

    This is ultimately the problem with linux. There is no defined platforms anywhere. Software that wants to use anything can't ever guarantee that it will be there. They aren't part of the OS, but rather, part of the users defined installation.

    Not quite: It's the task of a distribution to make sure all needed libraries are in place. I concede there is some difficulty when codecs and formats are not fully standardized. In that case, proprietary distributions stick on their homebrewed format and don't care about compatibility. A problem with FOSS is that users want it to be compatible with any other format.

    And who wrote "This is compounded by FOSS users being tolerant of crashy software because it suits their ideology"? I experienced running and even buying Adobe and Microsoft packages. They have all the defects that RMS keeps on warning about, and if you do it as a hobbist you likely end up with some 8-year obsolete software that cannot be mantained and hardly works. I'm not going to buy any more of that to avoid getting locked in it that way. Is that "ideology"?

    The reason why that software crashes so often is that it is underfunded. So, I could pay 300 bucks to get Bitwig, or do what I can with Avdemux and maybe donate them some 10 bucks. Maybe I should consider paying 50 bucks per month per license to use Premiere. Now, yes, if we go down to consider what should the price be proportional to, we may be approaching some ideological thinking.

  7. Re:A Simple Retort on WSJ Refused To Publish Lawrence Krauss' Response To "Science Proves Religion" · · Score: 1

    Nowadays we see a good deal of traditional activities, such as commerce, banking, socializing, studying, voting, and so forth, going more an more "online". Those transitions involve moving the roots of feelings, beliefs, and trust from an area to another, different one. It is an epochal change of paradigm, probably comparable to the invention of writing. What surprises me is that science and religion don't seem to be eager to participate.

    While gravity is an easily recognizable effect of mass, there are objects, like the photons, whose existence as particles rather than waves can be argued about in vain, much like the existence of God. Their statistical treatment, as given by quantum mechanics, apparently violates any classical scientific method, so that one can never know whether a single photon exists and which slit did it go through. A shifted paradigm could emphasize the information transferred, rather than the energy, just as if reality were virtual.

    I'd rise a similar objection to your exo-cake argument. In an accelerated universe, God's space and time coordinates are relative. No point in discussing which existed before which. IMHO, it would be more fruitful to concentrate on what's God's role in processing and transferring information. After Gödel's theorems, it seems that something beyond logics has to hypothesized in order to describe the universe well, even from a scientific point of view.

  8. Re:A Simple Retort on WSJ Refused To Publish Lawrence Krauss' Response To "Science Proves Religion" · · Score: 1

    Something seems to be less accurate than it might have been:

    The nature of God is such that it cannot be proven. Otherwise, we lose the choice to believe.

    We can prove our logical thinking, not physics. Science often simplifies things by modeling a part of reality so as to apply mathematical tools. We cannot prove that reality exists as we perceive it and that our model captures its essence correctly. That requires us to exercise our choice to believe.

    That said, science has yet to prove what the universe is, so how could we expect it to prove something outside of it?

    God, or whatever our souls perceive or believe, is "inside" the Universe, since we define the Universe as the totality of what exists. By the same argument, our minds are part of the Universe too, albeit physics gives little consideration to virtual-reality models that would result from a mind-centric perspective of reality.

    If anything, Lawrence Krauss' conclusion that Religious arguments for the existence of God thinly veiled as scientific arguments do a disservice to both science and religion looks a bit rushed. There must be a better way to put it.

    Port 25 is mainly used for relaying (which is what confused me). Malware doing direct-to-MX SMTP does in fact use port 25. Modern clients should be configured to use port 587 instead. Since port 587 (MSA) requires sender authentication, there would be no reason to block/intercept it.

  18. I think we all agree that predicting earthquakes (or weather, or stock exchange, for that matter) is not an exact science.

    Actually, upon re-reading your reply, I'm not sure what you were actually arguing.

    An expert's prediction —especially if officially appointed— should be solely based on her or his knowledge and beliefs, free from external pressure, lobbying, or prejudice. Scientists who are in conflict of interest because their opinions are too intertwined with their wishes should either stay silent or explain their position clearly. Legally, appointed experts who (ab)use their role for channeling spurious advices should be sentenced. IANAL, but it seems to me that would have been straightforward if the subject had been of financial rather than geological flavor, correct?

  19. In fact, there was special likelihood of an earthquake.

    Is this true?

    Yes. There had been smaller "warning" shakes. As a matter of fact, there have been families who were going to leave l'Aquila as a precaution, and changed their minds after hearing an appeal to keep calm and stay home, on the radio. That was narrated by survivors. There had been some political pressure, aimed at keeping order, to have those scientists sign that appeal. No illicit deals were proved, and even if there had been any, they can be considered part of Berlusconi's style of administration. Governors command, subjects obey.

    There is no reason to believe that a prediction, which will never be more than a general notion of increased likelihood over an indeterminate period of time anyway, could possibly save lives.

    It is not the usual kind of "predictions" (or opinions), which are common in such cases, but rather the propensity to give false, unjustifiable predictions in order to keep people calm. The latter sounds like "we don't care if you die or not, but please do it silently."

    As is often said, earthquakes do not kill people, unsafe buildings kill people. The buildings that collapsed and killed in Italy were unsafe obviously, and many of those that collapsed were extremely old. Where is the court case about the council (or whoever it ought to be) failing to earthquake strengthen a town full of mediaeval buildings?

    Sure.

    The reliability of email worsened as a consequence of spam and tentative mitigations thereof. Typically, poorly rated messages end up in spam folders and remain unnoticed, irrespective of their legitimacy. That behavior can be client-side only, but more often decisions are made by the receiving server too.

    By direct interaction I mean a transport-neutral setting. For example, "Recovery: server.domain.com is online" could be enhanced to something like, say, "Recovery: server.domain.com is online. Further on/off messages are suspended for 8 hours unless you click <here>." The sender can use a general-purpose notification manager that recipients can configure online. That probably works better than mixing those notifications with the rest of email and let a general-purpose email client sort them out.

Spammers don't know why their ads work, and don't want to. They turned marketing into a non-cooperative game.
