News about E-Ink

E Ink: Entwickler-Kit mit elektronischem Papier – Golem.de
(the corresponding PR announcement)

go on, go on, go on. that's what i want. i don't like reading on the screen very much. i waste tons of paper just for printing internet pages and reading them, e.g. while travelling around through vienna by tram.

unfortunately the e-book device development seems to have stopped in 2002. i hope that this will push forward new products, although i believe there wouldn't be an affordable one within 2 years. in the u.s. give europe another year. :o/

an additional note to the hardware developers: don't even think about a two-display/double-page e-book device. that's what i always hated about books. when reading while lying the next page is always uncomfortable to read.

still one more: don't mess around with supporting a lot of document formats. just pdf will do (flexible os'es let you save any printed document as pdf).

ahh. one more: underlining words on such a device would be too much comfort for the beginning. needing a touchable display it would be too much work. postpone it. please.

now for the last point: use e-ink. it only needs energy for displaying new pages. this will make the battery as long lasting as i want it to be.

Setting up exim4 on Debian

i have been dealing with setting up a mail server, lately. debian seems to have a preference for exim. most of the mail admins i know also support this. so i had a look at this.

as it always happens to me, i start with a not so easy scenario, but after some figuring i got it, mostly by following this guide: Configuring Exim4 and Courier IMAP under Debian GNU/Linux.

what the article does not say (and might be common knowledge — i will still describe this here for anyone who does this the first time) to have mails addressed to domain xyz.com be sent to the appropriate mail server, there needs to be a so called MX entry (mail exchanger). See also section 5 of RFC 2821.

I've got some more useful links on this topic:
Virtual Domains with Exim + Courier-IMAP + MySQL
Eleven Examples for Configuring Exim
Secure Mail Relaying with Exim and OpenSSL

there also is the Exim FAQ and the Exim documentation, but I'm not to fond of lots of on-screen reading.
