I wanted to typeset a 6x6 grid, with each cell framed, and a PDF image in each cell -- and with the center 2x2 square replaced with another image. Except for the center "window", it is trivial with pdfpages. With the window, I could see no good way to eradicate the frame lines in those cells, or put them back after the fact.

I also tried doing it in four blocks (above the window, to the left/right of the window, below the window). The main problem there was the scaling. I saw no easy way to scale the 2x2 left/right blocks the same as the 6x2 top/bottom blocks, since the scale factor was not predetermined and not known. (I think I'll ask the pdfpages author to write out the calculated numbers in the .log.)

I ended up using plain \halign, just the way the TeXbook says to do ruled tables :). The entire template was &#&\vrule width.5pt #\cr (the leading & repeats it as often as needed). Turned out to be way easier to have complete control in this case.

Posted something of a planned schedule for TeX Live 2011. Slippage of months would not be unusual.

Posted registration page and more information for TUG 2011, to be held in Kerala, India this October.

Think I got the new 0.8.3 release of biber in TeX Live's Build and Master trees. So many special cases, oh well ...

Been enjoying James Gleick's new book, Information. A quote from Ada, on trying to (what we would now call) debug her programs for Babbage's (theoretical) Analytical Engine:

"I am in much dismay at having got into so amazing a quagmire & botheration."

More info on TUG'11 in India. Registration form, bursary applications, still coming. If questions or ideas, email tug2011 (at) tug (dot) org.

Finally installed biber in TeX Live, that is, the precompiled binaries made by the authors (with Par::Packer, which I hadn't known about before; very cool). We'll see how many other TL builders want to try ...

In order to do the equivalent of "git pull --dry-run" (which doesn't exist as such) --

git fetch git diff master origin/master

(From Jim Meyering, thanks Jim. He admits "There's probably a much easier way".)

Belatedly learned that Randy Kobes passed away last September. Apparently the university is keeping his machine up, since the CTAN and GNU redirectors have been cruising happily along. Started reimplementing them elsewhere now, though ...

dvips work for a change: hopefully fixed a bug that was causing nan in output with eepic figures (reported by Stefan Moser). Squaring a not-so-big int can easily give a negative number :). I guess it was somehow hidden before (bug was not in any version until 2010) by a final cast of the result to float -- switched to double to eliminate warnings, I guess. One thing always leads to another ...
