I email him prolly immediately when I saw it, and I think I was

??? I don't remember it being down but
root@katri ~ # uptime
04:11:40 up 18 days, 9:59, 1 user, load average: 354.47, 354.33, 353.97
suggests it was. Anyway I am supposed to move to new server.

I think
http://collec.repec.org/nodes/x/u/2.html
has your current ranking at source in CollEc. It can change
every day.

What meeting exactly? If I see what they work on, maybe I can see
if I have technology to offer.

I could spruce up that document for the occasion. If you send me a
list of questions that would be helpful.

Up for grabs if somebody wants to take it over. Rewriting it in
Python would not be hard because the web interfaces is
written in XSLT, so you don't have to redo that. In fact
it would probably be quite easy to redo the computations
in Python, and leave the search in Perl.

I can deliver the full CollEc data via rsync. I just set it up
krichel@trabbi~/collec$ rsync -va rsync://collec.repec.org/table collec.txt
receiving incremental file list
created directory collec.txt
./
CollEc.txt
sent 46 bytes received 8,097,988 bytes 2,313,724.00 bytes/sec
total size is 8,095,907 speedup is 1.00
This tabular data. It updated every day. I already deliver full
path data to Nikos. It's bulky
icanis@katri:~/icanis/paths/ras$ du -s biwe
140757804 biwe
If you make it to the city before Mach, we could meet. Or
if you can pay my LIRR tickets, I can come to Stony Brook
and give a talk about this work.

I know. I lost contact during an o/s update, but the sponsor
has put a two-factor authenticication to the Hetzer interface
making a reboot impossible.

I'm on the case. The search seems to run fine when the CGI
is invoqued on the command line.

I have seen this bug appear before, but it has never been clear to
me why it appears. Usually a restart of the icanis server---which
handles queries submitted to the web---fixes the issue.
I did an o/s upgrade on the server, and rebooted, it seeems
to have fixed.
BTW, the complete data, with all the paths is available if
you want it.
