    I first saw mention of circuits that could bypass failed areas in a mid 1980s article by Sir Clive Sinclair, who argued it could be used to produce wafer-scale technology. The errors in the wafer would be unimportant, as they'd all be bypassed. Of course, this isn't what I'd call "self-healing" (where circuit switches go along with some sort of effort to repair the original damage if possible), but actual repair - beyond perhaps some sort of robot-wielded silver pen to re-connect broken tracks on a circuit board - is far beyond modern technology.

    X-Ray fluorescence must work at scales comparable to X-Rays, and X-Ray fluorescence works on the scale of the inermost electron shells and/or the nucleus itself. That seems simple enough. They needed features half that in size. That's a much harder problem, but it would seem solvable. There are probably crystal structures that would do nicely, but there is a much geekier way to do this. Superconductors have lanes runing through them that can be considered ice-skating rinks for electrons. These lanes may actually be too narrow for longer-wavelength X-Rays, but should be fine for very short wavelengths. If the gap is too narrow, then try a different approach. Get two magnetic (or one magnetic, one superconducting) materials with damn-near-perfect flat surfaces. Use magnetic fields to repell one material the required distance from the other. (The advantage of superconductors is that there should be less noise and therefore more control.)This allows you to tune the system dynamically, and the quantum step for a magnetic field is far smaller than any particle yet discovered.

    This would seem a good time for Google to support WAIS searches, for Apache to support streaming the HTML text via Gopher, and for file delivery to take place using FSP. Better yet, have a large set of supportable (and recognized) protocols, which the browser can pick between at random. If you like, have a proxy in front of standard servers that can transliterate between the formats.

    Alternatively, this might also be a good time for servers to activate opportunistic IPSec. It's not perfect, as people have pointed out on here many times, but it would complicate surveilance.

    More to the point, since I'm not sure the FBI are the biggest threat, it would stop passive monitoring by crackers. Passive fingerprinting and other non-intrusive methods of gathering information on software in use, potential vulnerabilities, etc, would seem to be one of the biggest vulnerabilities that modern systems do not seriously address. If someone wanted to launch a serious cyberattack, you think they'd run nmap at the time and have every active NIDS system slam down defences? Go and read the story about the Internet Auditing Project. Pay particular attention to the section where their main computer was hacked and the kernel patched with spyware in under 5 seconds from start to finish.

    The attackers had obviously mapped everything running on the computer - including the Linux kernel version - and had the entire attack pre-programmed supremely well. If anyone wanted to get serious, that is how I'd expect them to operate. It's much harder to detect and in the past 5-10 years, the techniques have probably improved significatly. If it's that easy to install a rootkit on a machine maintained by people who were clearly not ignorant of security issues, then given that most machines are NOT maintained by people with any real knowledge of security issues, the potential for either spying or actual harm is significant.

    Of course, all this requires a lot of knowledge - knowledge that can't be obtained if the traffic is kept secure, but knowledge that is broadcast for anyone to see if the traffic is insecure. Yes, yes, yes, encryption is slow. That's why there are encryption chips - and both the Linux kernel and OpenSSL can take advantage of some of them. Most computers do not have such chips installed, but if you're going to have Governments running around telling people what to do, I'd far prefer the Government to mandate (and preferably pay for) strong (as in no known vulnerabilities, no viable brute-force methods will work, 128-bit or more effective key strength, believed tamper-proof) encryption, with international gateways taking care of any difference in standards or lack of such protection.

    Yes, IPSec means the Government can't spy on the traffic, but frankly since cybecrime can be broken down into two major groups (attacks on systems from the outside, and insider assistance) where both groups are largely rendered ineffective by strong encryption, if there's no remaining serious crime to monitor, then there is no valid reason for them to do so.

    Yes, we know that crime has nothing to do with it, but it's unclear that domestic spying does either. If it did and they were competent, they'd have rootkitted 90% of servers in the US and be able to see virtually everything already and they need no further rights or access. If they're not competent, then they won't be able to do anything with the traffic anyway, so it's of no consequence whether they see it or not. If you're THAT concerned, use source-based routing and ensure that the packets are split randomly between multiple paths. Any monitoring system will then capture only a fraction of the packets and be incapable of analyzing what you were sending. Or use IPv4-over-IPv6-over-IPv4, set up two IPv6 tunnels with load-balancing between them and bounce your traffic via the 6Bone to two completely different exit points back onto the standard Internet. Does the same thing. There are probably regular IPv4-to-IPv4 proxies you could use to the same end. Or use Tor. Point is, you can't read a stream you can't see, and there isn't the compute power on the planet to recompose a fragmented stream except at the point it is intended to be recomposed.

  7. Looking at the IIS forum... on 500 Thousand MS Web Servers Hacked · · Score: 3, Informative
    ...the first person to google for attacked pages only turned up ASP pages as cracked. Later on, they say that the javascript attempts to use an ActiveX control. If I am exceedingly generous, I'll allow for the possibility that the story was written by someone who saw just these two comments and assumed that since both of these are generally run on Microsft OS', that this was an IIS problem. (Actually, more than a few people using Microsoft OS' run other web servers. There's quite a selection to choose from. Also, both ASP and ActiveX are usable under Linux, well, ish.)

    However, it is now abundantly clear that the attack is NOT ASP-specific, and just because one of the vectors it tries is based on ActiveX does NOT mean it doesn't try other methods. It only means that the people who spotted it early spotted it trying that method. Although it's unlikely to have an attack library for multiple OS', it would be surprising if it didn't have some alternative action for when ActiveX isn't available.

    I'm concerned about the number of Government sites that have been shown to be vulnerable, especially (as has been commented by others on Slashdot) a Canadian site dealing with national security. This attack is unlikely to cause any particular lasting harm, but stop and think. These are the sorts of sites that actually need to be secure. Even if not directly connected to internal secure networks (and I'd be willing to bet that far more are than are supposed to be), they are high-profile and for that reason alone are likely to be much more at-risk than other sites.

    Most smaller websites are just point-of-presence and information sites. It's an irritant if they vanish for a while, but it's unlikely to hurt anything. Nobody is going to die if a blog site isn't available for an hour or so, unless they're a serious addict. No small vendor is going to lose business if their PDF datasheets aren't reachable for a little while.

    You are correct to be suspicious. The other event I mentioned was much stronger - there was a definite genetic bottleneck, there was a geologically determinable drought, there was a reduction in human activity, and humans were still more-or-less in one region and thus much more likely to be affected by a drought. Numbers can be calculated directly from evidence of remains, but also by looking at what would have existed in the way of food and water, then calculating the maximum supportable population. You can do that with a single cluster.

    This newer claim must be treated with caution, because it involves humans that have spread out (less likely to find remains, less likely the humans would have been affected catastrophically) and it's much harder to calculate numbers, because it's much harder to determine what would have been available to whom and what level of trade would have existed when levels of critical resources differed between human-inhabited areas.

    DNA is also a dangerous thing to go by. We know there was a mitochondrial Eve, and we know a date but not whether it was the date of the event horizon (the point at which all surviving humans were descendents of Eve, within a timeframe in which differences in mtDNA would not yet be significant in the only regions we have really mapped for such purposes) or the point of singularity itself (when Eve lived). We also don't know why homogenious mtDNA occured - unless it conveyed such dramatic advantage as to be always selected (mtDNA handles energy conversion in cells), there's nothing that makes it obviously preferential, so all mtDNA lines should have survived on a completely random distribution.

    Only twelve descendent lines exist in the whole of Europe and Asia. Another eight pretty much covers the rest of the planet. I say "only", but remember at least one actual catastrophic drought and this supposed one happened much later than mtDNA Eve. If a uniform, homogenous strain was preferential, we should not be getting such divergence now. It's not a simple picture.

    (Also, dating an event by mutations is dangerous, since mutations can revert, not all markers mutate at the same rate, and all kinds of other factors make such calculations extremely messy. On the DNA mailing list, people often point out that the margins of error on last common ancestor calculations are so broad as to make the calculation worthless.)

    It's a Douglas Adams kind of situation: even if we knew for certain, we wouldn't really know what it was we were certain about, or indeed that we were even certain about it.

    You don't have to go that far. Microsoft simply picks one or two of its technologies that work well with one group of the things that needs defining, and makes sure that it defines that group according to how its technology works. Instant specification. Better yet, the specification can then be completely open as the only way to implement it "correctly" is via a technology Microsoft has patented, and since that's how all IE browsers will implement it, that is how those elements will be understood and used by web developers.

    This tactic works best if said group of elements is big, so that other browser developers back off from implementing the tags or guessing the syntax until they are better-defined. That way, Microsoft is pretty much assured that what they implement must be the de-facto standard, even if there is resistance within the W3C. And whether you agree or disagree with the decision, de-facto standards resulted in HTML 3.1 (which had maths tags) being dropped entirely in favour of HTML 3.2. There is precedent for Microsoft telling the W3C what it can and cannot make standard.

    Oh, it would have taken more than one such event, but we know that more than one such event occured. There have been other reports of other droughts nearly killing off humanity and the bottlenecks showing up in the DNA. Once humanity fragmented globally, however, mutations would have stayed reasonably local, and this also created races. (The two African tribes mentioned in the article formed from the drought mentioned and the Australian aborigines formed from early geographic isolation, making the three very special examples of humanity, but that should not lead anyone to conclude they should be treated as ouside humanity - they've a greater right to the title than most extremists.)

    The rest of humanity spread out across the globe, the Genography project has some nice maps of how the genetic markers show humanity to have moved. They do make one error when it comes to Europe. Europe was settled at least twice - once by a long-headed hunter-gatherer people and then later by a rounder-headed farming people. The long-headed people are the ones who developed lactose tolerence and anyone who can digest cheese or milk in any quantity is descended from the long-heads. In order for that to make sense, the long-heads must have migrated with cattle or goats, much as many nomadic tribes do today. The Iron age "Ice Man" (central Europeans give them such boring names - at least Britain's bogman was called Pete Marsh) was, if I remember the description correctly, one of the round-headed people. He was also left-handed, but that probably doesn't signify anything of interest.
