  1. Explicitly---IP number is not evidence of anything on California Judge Denies Discovery In Bittorrent Case · · Score: 2

    In case I wasn't explicit enough: an IP number may be intended to indicate a particular "bill payer," but the presence of a particular "bill payer's" IP number on a packet is not evidence that the "bill payer" was in any way, directly or indirectly, associated with the creation of that packet.

    And it's not clear at all from the reports whether the IP numbers in question were taken from packets supposed to have originated from that address, or from packets sent to that address. In the latter case, this is just like junk mail addressed to me---I do not take responsibility for it.

  2. Anyone can write any IP number anywhere on California Judge Denies Discovery In Bittorrent Case · · Score: 4, Interesting

    An IP number isn't even vaguely comparable to a license number. These IP numbers are taken from IP packets that could be written by anyone, anywhere. They are comparable to addresses on envelopes in the US Mail, except that there's no handwriting to analyze and no authoritative cancellation mark to identify the general location.

    Anyone can write any IP number in the sender field on any IP packet and send it to any other IP number.

    Even if you establish that a particular ISP has assigned a particular IP number for routing packets to a particular customer, you have no evidence that a packet marked with that IP number has anything to do with that customer, unless you can get much more stringent information from router logs and/or content that only that customer could have produced. I've never heard of any such evidence being presented.

  3. More fundamental flaws on Mobile Operators: Creating Artificial Demand For Capacity? · · Score: 4, Informative

    If demand is high, prices rise. If demand is low, prices fall. Simple, but true;

    Well known, and simple, and often false.

    The textbook model of supply and demand curves works under a set of very stringent assumptions that are often false. It requires rational agents, fine granularity of transactions, fine granularity of agents on both the supply and demand sides, isolation of the market in question from other markets, durable goods that can be withheld from the market, ...

    The model ignores marginal costs, opportunity costs, asymmetrical knowledge, asymmetrical market power, ...

    E.g., in markets for commodities with large fixed costs and small marginal costs, a reduction in demand often yields an increase in price. The suppliers divide fixed costs over a smaller number of transactions. If the remaining demand is sufficiently rigid, they can get the higher price, at least for a while. This phenomenon can lead to a further reduction in demand, further price increase, and a market failure at the end of the spiral.

    E.g., if there is a sufficiently flat segment in the supply curve, and a large buyer knows about it, the large buyer will pay a price at the low end of the flat segment, even though the a priori demand curve intersects at a much higher price. The large buyer will not consider the isolated value of the commodity, but the marginal value of paying more, vs. other uses for that money.

    These are just two of myriad examples where the simple "law of supply and demand" that everybody knows is false.

    "What it looks like" isn't really so important. The functional properties, in the complicated environment of a cell, are important. This quote from the Watson/Crick paper catches the important part:

    Yes, it's the pairing of bases between strands, the freedom of ordering bases along each strand, and the implications for representing and copying arbitrary sequences of characters that are truly important.

    For some reason the phrase "double helix" is always quoted. "Double" has some significance, but the helical shape is not particularly important. It's a natural result of the uniformity of the chain independently of the attached bases.

    It seems that Watson and/or Crick understood what was important, but the biological community seemed to focus on the geometrical structure rather than the information processing capability.

    If Speak for Yourself posts the source code under an open license, and make no money from it, then they are safe, right? And since when does a hardware patent apply to software? And doesn't prior tech void the patent?

    Alas, they are not safe. Patent infringement applies to all use, whether profitable or no. Current patent policy applies to software, and even business process, as well as hardware. Whether there is legal infringement depends on the details of the claims, which are very hard to evaluate. If there is prior art, that may invalidate the patent. But the relevance of prior art to the specific claims is a fuzzy issue. Also, once a patent has been registered, the burden of proof is on the alleged infringer regarding prior art. OK, IANAL, and I'm writing from memory, so this should all be checked, but I'm pretty sure I've memorized these points correctly.

  8. More on dating the "1946" EB on Wikipedia Didn't Kill Brittanica — Encarta Did · · Score: 2

    I read through all the head matter, and found no details on the timeliness of the material. The "Editor's Preface" brags about the timeliness ("the Britannica is never old"), but gives no careful details. Individual articles have no dates.

    The edition with the 1946 copyright has an article on "WORLD WAR II" mentioning dates all the way up to the Japanese surrender "On Sept. 2, 1945." It mentions that "U.S. armed forces began to land ... to assume their occupation duties."

    The KU KLUX KLAN entry mentions "the World War," but it didn't need to be updated after the destruction of the 2d Klan. The WORLD WAR II entry has information on the Nazi party more timely than the information in the NAZI entry. But the NAZI entry does not cite any other article for more information.

    I still like djl's longtitudinal comparison idea a lot (some other entries, eh? ...), but the skew between different entries makes it more complicated. We're getting a snapshot of the presentation of a given topic before a given time, distorted by the priority with which it was revised. Lovely problem in signal separation.

  10. Re:1946 Britannica on Wikipedia Didn't Kill Brittanica — Encarta Did · · Score: 1

    Interesting that the '1946' set seemingly refers to the Nazis as a going concern, even though the end of WW2 and Hitler's death was the previous year. Goes to show you that they probably didn't revise the thing that often (or rather, that it took a long time for revisions to make their way into the actual published books).

    I am soooo embarassed that I didn't catch that myself. I looked very carefully again, and the set is marked "Copyright 1946." I can find no other indication of the date, but I didn't read through all of the head and foot matter. The copyright and printing are US. It's possible that there was a delay between a UK edition and a US (can somebody check that out?). But they are already being "published with the editorial advice and consultation of the faculties of the University of Chicago," so if anything the reverse delay is more likely. I checked the first and last volumes, and the one with the NAZI entry, just in case I had bought an accidentally mixed set.

    I got the set with yearbooks dated 1946 through 1949. The "1946" yearbook is also Copyright 1946, it is supertitled "A Rocord of the March of Events of 1945," and it contains the "Calendar of Events" for 1945 (by studying the day-to-day account of the end of WWII in the 1946 yearbook, I embedded the erroneous notion that the war had ended in 1946 instead of 1945).

    So, I have a hypothesis, which I hope someone has the energy to check out: EB writes the encyclopedia (actually, mostly just revises older entries) in 1944, puts stuff together in 1945, and registers copyright at the beginning of 1946, perhaps to maximize the length of coverage. During 1946, they write up the "March of Events of 1945," copyright that later in 1946.

I find this article more objective in tone than the one on communism.

    I was acquainted with some people at Britannica in the 80s and 90s, and others in publishing (not well enough acquainted to be a leak, just to form an opinion that might have value). It seemed to me that Britannica was stuck on being the encyclopedia that everyone wished they could afford, rather than the encyclopedia that everyone used. Similar things happened in other domains where the effective price point changed suddenly. You go from being the dominant choice in a small but expensive market to being almost nobody's choice in a much larger and much cheaper market.

    I think that it's the same phenomenon that killed Apollo. They had the best (pretty much only) desktop research computer workstation, only affordable by very well funded labs. SUN Microsystems offered a much cheaper, inferior box, running a UNIX that was not yet as well engineered as the Apollo proprietary system. But the new, cheaper box, and the preponderance of UNIX on research minicomputers, provided a UNIX solution for almost everybody. Soon, even those who could afford Apollo found it more effective to buy lots of UNIX instead of a little bit of Apollo. I remember an almost tearful Apollo engineer, toward the end, promising that they were finally going to provide UNIX and cut their price. It was too late.

Better to put it out there, and let all sorts of unforeseen uses arise. It's possible (I think likely) that most uses of cryptographic gibberish names would not be on the direct communication path between customers and branded vendors. The service can be very cheap to provide---Google could do it in a flash, a number of academic departments could do it as an experiment. If there were no impact on conventional DNS, that would be OK. My hunch is that it would relieve some but not all of the pressure on DNS that causes so much energy to go into struggles for control, and would provide a useful safety net for those who get stomped on in the DNS game.
