Some Decentralization papers for the day

I know it’s a little rude to just post links and little more, but I at least wanted to note four papers I came across today. The first is pretty fanciful, but I think it actually speaks to a real set of problems for programming “mass quantities” of computing devices: Spray Computers: Frontiers of Self-Organization […]

Dvorak Disrupts ‘Disruptive’ Tech Label

I loved this piece. I fell into it from a link to Dvorak’s 10 best and worst laptops of all time in Good Morning Silicon Valley. It triggered a bit of melancholy refelection that very, very few of the folks in the field today even remember the 80s, much less the 70s — the installed […]

Defcon 12 Trip Report

Adam and I just got back from a few days in Las Vegas to see the (astonishingly young!) face of the computer security, ahem, ‘adversary’ community at the 12th annual DEFCON. We found several useful sessions on the fringes of electronic commerce (‘real-time penetration of credit card networks’, ‘the farmer’s market model of pseudonymous dealing’, […]

NYSE prices update at no more than 0.25 Hz (!)

Latency matters — and embedded within this little trick forced by Reg NMS, is an agency conflict to boot: who’s really motivated to give me, the little guy, the best possible price?? NYSE To Further Upgrade Automated Execution System The New York Stock Exchange next week will unveil a plan for further upgrading its automated […]

Tagging Pharmaceuticals

Ross Stapleton-Gray writes: Project Jumpstart, discussed in this article, is an effort by major pharmaceutical manufacturers to test item-level RFID tagging of drugs as an anti-counterfeiting/theft strategy. In considering the surveillance issues, drugs are certainly a sensitive issue; on the other hand, it would be easy to “shed” the tags, as an end consumer. My […]

Your Medical History On A Microchip

Laura Landro’s Informed Patient article in the Wall Street Journal on July 27, 2004: The idea is to put together records that patients control and manage themselves, collecting data from different providers and sharing it as they see fit. Consumers surveyed by the group Connecting for Health became receptive to the idea of electronic medical […]

RFDump

Anders at RFID Buzz notes: German security consultant Lukas Grunwald has released a tool he names RFDump, that can be used to read, and apparently in some contexts, change the contents of an RFID tag. Handy for discounting your purchases, you’d think, but as far as I can see, this would only apply to read/writable […]

SOAP or HTTP as the basis for TP

Mark Baker responds to Rohit’s Teepee post: Depending upon your POV, TP could either be PEP/SOAP (or similar), or HTTP itself. mod-pubsub probably best reflects the latter position, but I could see value in the former. I’m not sure that there’s much in the way of a significant architectural difference between the two, but the […]

XML Overhead Considered Harmful

Matthias Nicola – Homepage Matthias Nicola, Jasmi John: “XML Parsing: A Threat to Database Performance”, 12th Intl. Conference on Information and Knowledge Management, CIKM’2003, New Orleans, November 2003. This paper, referred to me by Rick Ross, is a fascinating indictment of the inadequacy of XML for large-scale, real-world applications today. Fits in with other work […]
