If we think of this as analogous to PGP, ie it encrypts the data but doesn't conceal who's sending or receiving it, then could the DBA perform something analogous to traffic analysis? For example, if the database stores a social networking site, Alice will look up database rows corresponding to her friends, and Bob will look up rows corresponding to his friends. If there's a row they both look up, the DBA can infer that they have a mutual friend. So would it be possible to imagine a system analogous to Tor that would conceal who was performing the queries, as well as the content of the queries?

The Word Spy for 05/01/2003 -- ethnomathematics
by Paul McFedries 05 Jul '18

05 Jul '18

ethnomathematics (ETH.noh.math.uh.mat.iks; th as in thin) n. Mathematics as practiced by non-Western ethnic groups and marginalized groups within Western society. Also: ethno-mathematics. --ethnomathematical adj. --ethnomathematician n. Example Citation --------------------------------- Starting in 1993, he traveled across Africa on a Fulbright scholarship to investigate evidence of fractals in windscreens, carvings and textiles. He explored villages -- once leaning precariously out of a small airplane to take pictures of layout patterns. His resulting book, "African Fractals," argues for a mathematical intelligence in African design more complex than generally appreciated. Eglash's research fits in squarely with "ethnomathematics," a term coined in the '80s and usually used to describe the mathematical practices of smaller or indigenous cultural groups. While ethnomathematicians have studied Mayan calendars and even boomerang flights, a unifying theme is an emphasis on mathematical accomplishments outside the Western canon. Advocates see ethnomathematics as a useful way to make math more expansive and relevant to students from different backgrounds. Critics characterize it as a diversion from numbers that could lead to softer standards. --Michael Hill, "In hair and Latin beats, professor creates math lessons," The Associated Press, April 29, 2003 Example Citation #2 --------------------------------- Ethnomathematics -- the general name mathematician Ubiratan D'Ambrosio of Brazil coined for this study of the concepts, practices, and artifacts through which we discover mathematical elements among peoples living outside or on the margins of Western culture -- teaches us to look at "exotic" forms of mathematics as an intrinsic element of the civilizations in which they have flourished, well worth studying for their own sake. --Dirk J. Struik, "Everybody counts," Technology Review, August 1995 Earliest Citation --------------------------------- Native American Mathematics appears at a time when interest in ethnomathematics is on the increase. Educational projects devoted to developing mathematics materials relevant to the Native American heritage, style of learning, and economic environment are currently under way at Northern Arizona University, Oklahoma State University, and the Fort Ojibway School in Minnesota, to name but a few. An International Study Group on Ethnomathematics has been established, a newsletter on the subject is being published, and international meetings have been scheduled. --Charles G. Moore, "Native American Mathematics (book review), Science, May 22, 1987 First Use --------------------------------- Ethnomathematics [is] the maths practised among cultural groups such as national-tribal societies, labour groups, children of a certain age bracket, professional classes and so on. --Ubiratan D'Ambrosio, "Ethnomathematics and Its Place in the History and Pedagogy of Mathematics," For the Learning of Mathematics: An International Journal of Mathematics Education, February 1985 See Also --------------------------------- design ethnographer: http://www.wordspy.com/words/designethnographer.asp edubabble: http://www.wordspy.com/words/edubabble.asp equity education: http://www.wordspy.com/words/equityeducation.asp fuzzy math: http://www.wordspy.com/words/fuzzymath.asp J curve: http://www.wordspy.com/words/Jcurve.asp mathlete: http://www.wordspy.com/words/mathlete.asp Words About Words --------------------------------- Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true. --Bertrand Russell, Welsh mathematician, philosopher, and essayist, _Mysticism and Logic_, 1917 Miscellanea --------------------------------- The WordSpy mailing list is available in an HTML version that bears an uncanny resemblance to the pages on the Word Spy Web site (see the address below).

[ZS] Neat wallet
by R|diger Koch 05 Jul '18

05 Jul '18

Bitcoin is the client from bitcoin.org, right? Wrong! There are a number of wallets. And the official client is more and more pushed into the role of a reference implementation. Use it if you know what you do, otherwise, there are better alternative. In fact you can (ab)-use exchanges like Intersango (https://intersango.com/) as a wallet. But that's not a smart idea. There are plenty of wallet implementations. There are limitations in Javascript that prevent running a wallet only in the browser, but some offerings are getting really close: https://blockchain.info/wallet https://www.strongcoin.com/ The problem here is that they still keep enough stuff on their server so they may take your wallet. I looked at some of the Javascript and it looked safe, but there is no obstacle to change this tomorrow. On the plus side: This wallet runs on everything that can run a decent browser and if you don't put large sums into it, it should be fine. Here is what you do if you want to store large sums and are as paranoid as I am: 1. Create a VM for this purpose (if you are paranoid, this is a simple "unzip" of a VM template) 2. Go to https://www.bitaddress.org in the browser of the VM 3. Disconnect your computer physically from the network (pull the network plug) 4. Generate the keys, using the "Wallet Details", using a secret key phase; copy the address on a memory stick 5. Shut down the VM and delete it 6. Turn off the computer and reconnect the plug 7. transfer Bitcoins on the address from the memory stick. -Anu -- Zero State mailing list: http://groups.google.com/group/DoctrineZero ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE

Re: [p2p-hackers] Codes for Error Correction in P2P Nets

A very good overview of all network coding for the purposes of data distribution (i.e., making digital fountains) can be found at: www.eecs.harvard.edu/~michaelm/postscripts/itw2004.pdf Some of the more interesting and practical codes, such as Raptor codes (discussed at the end of that paper), are covered by patents. Another network coding that is comparable to Raptor codes is Online codes. The following paper, by the creator of Online codes, presents an efficient algorithm for downloading large files using them: http://mnl.cs.stonybrook.edu/home/karthik/BitTorrent/papers/incentives/tore… /rateless_codes.ps IIRC, the creator of Online codes -- Petar Maymounkov -- started a company Rateless and was going to patent them. But Online codes fell into the scope of Digital Fountain's patents, who own the Raptor codes. So I don't know who owns the patents for Online codes anymore, but rest assured they're patented :( - Mike Quoting Nigini Oliveira <nigini(a)gmail.com>: >Hello All. > >I'm researching these days on some kind of codes that helps the distribution >of data at networks (Error Correcting Codes).

There are a couple main types of use cases for this kind of capability: A) emergency situations of various types like the Egypt blackout and B) getting communication and sharing working in more misc. ambient conditions (poor coverage in a building, on the train, etc.). There is a big use case for this that will give it a workout that is sort of a simulation of the first of these and with a good need for the second: Burning Man. Many people in a refugee-like camp, no commercial wireless or land line, a desire to communicate in various ways, a high percentage of techies with smart phones, all running an experiment for a week. Seems like a perfect testing ground. We have 6 months to be ready. I hereby declare project: "Egyptian Light" (to counter blackouts everywhere ;-) ). The point of this is to shamelessly combine every existing technology that provides a piece of this and then fill in the missing pieces. Even better: http://egypt.annourbis.com/egyptian-gods.html Chons - "Egyptian god of light in the night... he also held the titles Embracer, Pathfinder, and Defender, as he was thought to watch over night travelers. As the god of light in the night, Chons was invoked to protect against wild animals, increase male virility, and to aid with healing." chons.org is now registered. Now, how is it pronounced?? There has been plenty of work with open source cell networks, etc. I haven't seen anything usable about hand-held mesh and/or store and forward capability yet. Ideally, you'd use bluetooth when in close proximity, with Wifi / cell for uplink, with Wifi also being used for wider proximity connections. The store and forward capability could be kind of cool. Limit it to SMS-like messages, enforce flow control, then floodcast, possibly with fuzzy geo-routing, as necessary for both unicast and broadcast messages. Get all roving vehicles to run store and forward nodes. Include time synchronization, then implement radio control for prairie dog activation for both battery conservation and channel multiplexing. The biggest hurdle will be security, including detecting and defeating jamming and spoofing of various types. I'm most interested in an Android solution that will work on most devices. Not only are they easier to hack, more open, easier to run untrusted apps, etc., but some of us are building a collection of obsolete devices that would be cool to use for this. Unfortunately, my pattern is full for a bit. But before BM2011, hopefully it will be far along. sdw _______________________________________________ FoRK mailing list http://xent.com/mailman/listinfo/fork ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
