Ever cursed a site you want to check periodically for not having an RSS feed? cron / msmtp / web2mail.com offers a slightly crude solution -- crude because you get the whole page every time, not just new content.
web2mail.com provides a means of receiving website content via e-mail. I use msmtp to send the request to web2mail.com via one of my e-mail accounts, and cron to specify the frequency and issue the e-mail.
(I first tried to send the e-mail directly from my laptop mail server to web2mail.com, and web2mail.com did not like my e-mail and bounced it. Thus the msmtp strategy.)
I setup one of my e-mail accounts in ~/.msmtprc as follows:
# 163.com account 163 host smtp.163.com auth plain from email@example.com user user password password
Then in a terminal issue "crontab -e" and add the following entry:
25 14 * * 1,4 echo -e "Subject: http://www.website-you-want-sent.com/ \n\n This is message body" | msmtp -a 163 -v firstname.lastname@example.org
which grabs the web page on the first and fourth days of the week at 14:25.
Have you ever wished someone would make your web browser "bookmarks" a useful place to store information? Someone has.....
The most efficient thing to do is view the excellent intro video on
Zotero is a Firefox plugin, which is both its best feature (right at your fingertips while browsing) and worst feature (I dislike the constraint of one application depending too much on another.... Firefox is not the only web browser in the world, after all.)
Basically it allows the collation and organization of a collection of notes, copies of web pages, external documents, pdfs, annotations and high-lighting, all into one place, that in this case is a box in the lower right hand corner of your Firefox browser window called "zotero". As someone who does a lot of research, I can say Zotero looks very powerful to me. It is not "just" a plugin, it is a big complex application that has been packaged as a "plugin".
I cannot find anything else even close to it in functionality within Debian Linux' huge software library. "referencer" has promise, but seems primitive in comparison. Unless it is buggy (don't know yet) I expect to make heavy use of Zotero.
