  Linux.com :: Portrait: Raph Levien, font-designer and free software contributor
His father, Jack R. Levien, is well-known as a producer of miniature books, and Levien claims that he learned his alphabet from his father's collection of font specimens -- "A for Albertus, B for Bodoni," he jokes.
Levien's more recent typefaces are licensed under the SIL Open Font License, at least partly to show his support for the growing community that he calls the free font movement.
Levien's fonts are available in a FontForge format, from which users can make their own modifications or generate their own PostScript or TrueType exports for use.

 SVG and its Path into the Linux Desktop
Raph was an early adopter, as the first public draft of the SVG specification wasn't released until February 1999.
As part of their plan, Eazel sought to use vector graphics instead of bitmaps and so hired Raph Levien to create a SVG rendering library to be used in Nautilus.
As things would have it, Raph was asked to take over maintainership of the Ghostscript project, a project that had a money-earning commercial venture built up around it.

The article originally stated that it was Raph Levien, who is designing a language called Ghilbert.
The benefit and importance of Raph's program (aside from its remarkable compactness) is that it provides a completely independent way to trust the correctness of Metamath proofs, decreasing the likelihood that a bug in the metamath program has let incorrect proofs slip by.
Raph has already written a proof verifier for Ghilbert and a translator from Metamath to Ghilbert.

Attack Resistant Trust Metrics Raph Levien, UC Berkeley (July 2004) Abstract This dissertation characterizes the space of trust metrics, under both the scalar assumption where each assertion is evaluated independently, and the group assumption where a group of assertions are evaluated in tandem.
We present a quantitative framework for evaluating the attack resistance of trust metrics, and give examples of trust metrics that are within a small factor of optimum compared to theoretical upper bounds.

 Cloudy Thinking » Blog Archive » Raph Levien: Inconsolata, an open monospaced font
Inconsolata is a monospace open font designed by Raph Levien.
It is a collaborative font project: you can freely use, study, modify, redistribute and/or sell the font under the terms of the OFL which means you are free to derive artwork from the font, to embed it in a pdf, to branch, extend and tweak the fonts to your liking.
Raph has been using his own font design toolkit called spiro to design Inconsolata.

When Raph Levien created Advogato, he said, While "Advogato" is a pun on the word "advocate," the goal of this site is quite different than the usual sense of OS advocacy or free software advocacy.
Raph Levien has written a concise summary of Advogato's trust metric system.
At the time of the site handoff, Raph and I talked about several ways to cover costs including asking for donations or possibly adding some minimal Google AdSense boxes, but for now I'm just monitoring things for a few months until I have a good idea of how much the long-term costs will be.

 cosmix.org | Inconsolata
A few weeks ago I stumbled across Inconsolata, Raph Levien’s monospaced font and it has since become one of my favourites.
Raph states that the completion of this font is sponsored by TUG and that donating to TUG would help finance the design and implementation of other fonts by him.
Your mention of the possibility for Hellenic characters for Inconsolata is thrilling (that’s not an exaggeration), not just because it is a beautiful font, but also because there is considerable lack of free Hellenic fonts.

I thought that Raph might appreciate OBJ3's modules and perhaps OSCAR's performance and flexible architecture.
Meanwhile, I continue to be interested in Mitch Kapor's new project.
And I'm still interested in Raph's trust metric work, too—in fact, I see some overlap between the RDF work and the trust-metric work, about which hopefully I'll have more to write at a future date.
