How I use Emacs

Planning

I used to use PlannerMode a lot. Then I switched my blog to Wordpress (http://sachachua.com) and started using Emacs Org + Toodledo for my task management. Now I use org2blog to post some entries from my Giant Org File of Awesomeness.

Communication

I used to use Gnus, the built-in mail/newsreader that slices, dices and juliennes - not as easy to integrate into a Windows-based workflow, though. When I used it, I had basic splitting set up to file my mail into separate groups neatly organized in a hierarchical tree that allows me to see at a glance how much mailing list messages I’ve received. I used “c” to catch-up groups or even whole subtrees, mark threads as read or even uninteresting. Adaptive scoring meant that I don’t have to manually specify my reading preferences - gnus learned what I don’t like to read, so that I don’t have to read related messages next time unless I really want to. I’d set it to score down all messages from hotmail or aol unless I like the author. ;) I elided mailing list identifiers so I don’t see those [….] things, banners like the ads at the end of yahoogroups, really long signatures or To: headers. Gnus is definitely a mail/newsreader for the netiquette-sensitive. :-)

BbdbMode integrated well with Gnus, so I could easily bring up or create contact records for the people I receive mail from. I had Gnus automatically add notes for the people I know, and it’s interesting to see what mailing lists people are subscribed to. I could add notes, check phone numbers, and even see when someone wrote me last. (Time to write a “Haven’t heard from you in a while!” note…)

Mail is a somewhat dangerous thing to experiment with, of course. :-) I had lost some outgoing mail due to masqmail silently failing if you specify the -f flag (evil!), but some debugging later turned up a message-sendmail-f-is-evil variable I could set to t. I have since then moved to postfix so that I could use + as an address separator, so I haven’t needed that.

(outdated - I no longer send text messages from my computer. I’m in Canada now, and text messages are expensive!)

Ah, yes, text messaging. SMS is pretty big here in the Philippines. I am a lazy computer geek who would rather type than fish out my cellphone and start texting. Besides, I kinda like having all of my text messages stored on my laptop - search, store, reply, and even see threaded displays. :-) I used to use gnokii, alamin, postfix, bbdb and gnus in order to have practically seamless SMS sending. :-) Here’s how it works. I’ve set up alamin (a GSM-SMS gateway that can talk to a gnokii-supported phone) to poll my cellphone for incoming text messages and convert any such to e-mail messages from alamin+<SOMENUMBER>@localhost to sacha@localhost. I receive those messages in Gnus in my mail.text group, and BBDB steps in to fill in the name from my contact database thanks to (gnus-summary-line-format “%U%-40,40uB %S\n”), (bbdb/gnus-summary-prefer-bbdb-data t) and (bbdb/gnus-summary-prefer-real-names ‘bbdb) in the group parameters. My reply is processed by postfix and piped through email2sms, a short Perl script I wrote that just invokes alamin’s client program. Alamin queues the message and tries to resend it at regular intervals until it is finally sent. No more dealing with “Message failed.” or lack of signal, and I get a full record of all of my text messages, and I can text while in class.. ;) Unfortunately, I don’t have a serial port any more, and my phone is not Linux-friendly. Can’t pull off this neat hack these days.

Taking notes

I keep my notes in plain text files. I find that typing on my laptop encourages me to keep more complete notes because I can type faster than I handwrite (and it’s much less tiring!). OrgMode makes it easy to keep my notes in outline mode.

Internet relay chat

ERC! EmacsIRCClient forever. Well, not really forever, but I’ve tried quite a few Internet relay chat clients and I must say that ERC is really cool. erc-track lets me keep track of channels that have changed even though I’ve got my notes maximized, and since it’s part of my editor I can easily cut/paste/navigate/tweak/do-funky-stuff. I hang out on Freenode #emacs, and it’s tons of fun.

  • 03:40 UTC Weekly review: Week ending February 26, 2021I worked on improving my streaming setup: I used pulseaudio to mix my microphone and audio output into a combined source, and I tested that it worked with speech recognition. I used gstreamer to make a video stream that was delayed by four seconds. The audio was a little tricky because the snap’s gstreamer doesn’t […]

  • 23:00 UTC Guest post: Bookmarking PDFs in Emacs with pdf-tools and registersSomeone wanted to share this post, so here it is! -— I read a lot of PDF documents on Emacs. I use the Emacs package pdf-tools for this. I also write a lot of LaTeX on Emacs (both in org-mode notes and .tex files). Frequently I find myself in the following situation: I need to […]
  • 05:06 UTC Controlling my stream audio from Emacs: background music, typing sounds, and push to talkUpdate: 2021-02-11: Parsed pacmd list-sources so that I can mute/unmute devices by regular expression.

  • 06:15 UTC Marginalia and hiding the value of password-ish variablesI like the way Marginalia adds annotations to minibuffer completion. I’m experimenting with streaming, so I’m trying to not leak passwords while playing around with marginalia. (I’ll probably mess up at some point. Please be nice! =) ) This is the annotator function: (defun my/marginalia-annotate-variable (cand) "Annotate variable CAND with its documentation string." (when-let (sym […]
