Susan Hohenberger defended her thesis Friday at MIT. Susan’s thesis work is on developing secure algorithms for proxy cryptography. These are new cryptographic constructions that are designed to allow a third party, the proxy, to take a cryptographic object produced for (or by) a particular key and transform it so that it is a valid object for (or [...]
There are some articles making the rounds today on reddit about math education.
Seattle allows great diversity in its math curricula. This is not without risk:
In Seattle, schools have a lot of autonomy in how they teach math. The district has adopted textbooks and provides guidelines and timelines for teachers to follow, but doesn’t require [...]
I recently installed DokuWiki on NearlyFreeSpeech; while I love DokuWiki’s features, I quickly noticed that I was being charged for more bandwidth than seemed necessary for the few pages I was viewing and editing.
A quick check of access logs revealed two things. First, DokuWiki does not compress its output using gzip. Second, it does not send appropriate cache [...]
Today a few of us had lunch with Yoshi Kohno who is visiting MIT and gave a talk about his research on Monday. An important aspect of Yoshi’s research is the problem of translating theoretical security results into secure implementations. He gave an example of how the way that WinZip employed the theoretically secure encrypt-then-MAC paradigm of authenticated [...]
Tim Daly, one of the developers of Axiom, has a vision for solving the following problem:
Computational science seems to be in a state where people work independently. They develop whole systems from scratch just to support their research work. Many make an effort to distribute their system but fail [...]
I came across Performancing while browsing the various winners of the Web 2.0 awards: they are ranked second in Web Development and Design. Their description sounded interesting for a new blogger like myself so I paid them a visit. I was surprised at how hard it was to find out about Performancing’s goals and products. Inspired perhaps by Jakob Nielsen’s [...]
