TheMuso:
If you are aware of Australian internet access, it is quite different to the rest of the world, particularly broadband. I am sitting here on a 512/128K ADSL internet connection,

I am not sure what you mean, "different", unless you mean very very expensive. My Melbourne ADSL costs A$170 per month for 512kbps and an embarrassingly small download inclusion. I presume you're luckier to be paying less than this extortionate rate.

Gah. Couldn't figure out why OS X's integrated WebDAV handling wasn't working (WebDAV servers are first class file systems on OS X). Eventually figured out the problem was my squid proxy server - which at 2.2.5-4 is too old (old Debian 2.2 install on Alphaserver).

movement: hey, thanks for pointing out the idiotic Olympic linking policy. Taken with their ridiculous stance on blogging it makes them look like a bunch of dumb shits.

raph: IKARUS and Hobby's method both combine, from a user p.o.v., on-curve points with circle segments. I have long believed that this is close to the optimal curve construction technique. Hobby gets bonus points for doing it within the ubiquitous cubic B├ęzier framework!

I'm not sure what you mean when you say IKARUS uses Hermite splines; as far as I know it uses circle segments between on-curve knots. This is confirmed by the FORTRAN code that Dr Karow included as an appendix to his book Digital Formats for Typefaces.

You're right about CMR versus ink spread/squash. Some offset printed books set in CMR were disastrously thin in their setting. Wolfram's The Mathematica Book was one example. Beautifully printed, with almost no ink spread or dot gain, but the CMR type used throughout was most unpleasantly thin! Knuth was somewhat savvy to this issue as the models he looked up to were letterpress works such as early editions of his TAOCP (which are masterpieces of technical setting). He did include some compensatory parameters in his CMR metafonts to deal with print machinery characteristics, but perhaps some high resolution fonts were generated with unwise or default values.

Many digitisations and revivals, particulary Baskerville, Century and similar, have suffered from an underestimation and/or underappreciation of letterpress effects. I believe this issue has been studied pretty thoroughly by revival-makers (revivalists?) in the last 20 years or so.

California sees the light: Terrific paper on "Exploring Open Source alternatives" from the California Performance Review. A state that bans electronic "voting" and is also open to Open Source! What a place.

mathieu, mpr: this may dampen your enthusiasm for Numerical Recipes.
mathieu: one friendly expert on floating point is Steve Richfield. I'm sure he - or another FP guru - can give you some good references if you ask on comp.arch.arithmetic.

When bush comes to shove

bolsh: Oh, he'll "win" it. Even if the puppetmasters have to rig another election. Smell a civil war brewing? That's what it will take to oust them. The issues are as serious as slavery... except... this time, we're ALL potential slaves.

If you think of the election as Oscar night, rest assured the name of the new incumbent is already written and sealed in the envelope.

(Pretty soon, we'll be able to skip the "campaign" and "party" and "voting" charades entirely. Just fast forward to the appointment.)

raph, are you familiar with the research of Lucas de Groot? It's mainly concerned with parameters such as weight and width, less optical scaling, but he's very knowledgeable about interpolation maths in typography. (And of course, the IKARUS program did a lot of the groundbreaking in this area too.)

A friend of mine here in Australia, Nick Summers, owned a hot metal type foundry and bought one of MFB's pantographs when ATF's equipment was dispersed. He and I also met an ex-ATF employee around 1992/3 who was working on next-generation typographic layout software (this is around the time ATF released PostScript format fonts in optical scaled series - late 1980s). His name escapes me for the moment. I think I still have a copy of the program somewhere.

(update) The ATF guy's name is Henry Schneiker, and here's a contemporary article he wrote, Type Technologies Illuminated. The program mentioned is ATF Type Designer I (v1.4 & 1.5b, 1991). Jens Alfke was also on the project. Jens has one of the most enviable resumes in the industry.

I found IKARUS M (Mac versions 2.5 and 3.0, 1992), too.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
