I set out to geek the heck out of Toronto's hippest geeks, and I did. I showed them Emacs as they'd never seen it before--and even that was a tiny fraction of my config. Lots of cool stuff behind the scenes, too. When I showed them M-x doctor (the Emacs psychotherapist), someone shouted out, "Is Emacs talking to you?" I laughed and continued. What I *really* should've done was break the sequence of my presentation, hook up the speakers, and tell them about Emacspeak - presentation sequence be darned. ;) Oh, if they only knew how easy it was to make jokes reality under Emacs! I remember writing my 'bot implants' - the hippie-expand code I used to answer questions really really quickly on IRC...
Anyway. That was FUN. And it was relatively easy to get through, especially with the cue system I made (Emacspeak rocks!). I'll talk about that some other time. It's a really cool hack and well worth exploring.
SO. The democamp.ca folks will eventually get around to posting a vidcast. In the meantime, I have a 431MB MPEG movie that I need to either downsample or cut up in order to put online, maybe on YouTube. I don't have enough memory or hard disk space to play around with this (have you seen my computer?!), but I'll happily put the video up if we can figure out how to go about doing that.
If you enjoyed the talk, missed it, or just want to hear/see me bounce up and down about Emacs some more, come to the Linux Caffe on Saturday (Oct 28, 2006) from 1:00 PM to 3:00 PM. I'll be there, and we might even see about having some kind of mini-show / vidcast. I wonder if David has a projector. =)
That was fun! Can't wait to do it again!

Check out this teacher-oriented article What's Your Name Again? by Mary !McKinney. It starts:
“I’m terrible at names,” complained my friend Steve. He’s a respected professor of entomology who is fascinated by ugly bugs that make many of us shudder. “Really?” I asked. “How many species of beetles can you identify by name?”
Heh!

It's amazing, looking out over a crowd of some 70 people and realizing that very few of them are strangers. It was my first DemoCamp presentation. I jumped at the opportunity to wear my beautiful white suit (I *love* that outfit!), but neither the suit nor the stage (MaRS is big!) imposed any distance whatsoever. It felt as if I was sitting around a table with good friends who indulged me by listening to an enthusiastic demonstration of my latest cool hacks.
It helped that there was a low table that I could put my computer on so that I could do my demo without hiding behind the podium. (I hate podiums and other things that stand between me and the rest of the people!) The microphones were good, too. I left the podium microphones in place, and my natural presenting voice was strong enough to get picked up without effort. And of course, a warmed-up sympathetic crowd was just *wonderful* to work with... =)
I can't wait to work on a few more things. A lower voice might be easier to listen to, as long as I can still keep my warmth and humour. A slightly higher table would've been nice. More structure for the hacks, maybe a clearer message? But it was a fun presentation, and I'm glad I got the chance to show people something crazy and fun.
I'd like to refine this presentation even further. I have an important message I want to share with as many geeks as possible. I want people to push the boundaries, to imagine what's possible when software can be customized to that extent. Maybe the benefits will trickle down to everyone else, the way wild ideas in research prototypes can be taken into the mainstream...

You are really becoming an great speaker ;) btw, I was hanging around the back and overheard people asking if you had gone yet - apparently you were the only thing they were there for! awesome!

It looks like my mail authentication has very quietly broken behind the scenes. I've been using SSH tunnel to get out to another host, and then TLS to authenticate against Jijo's mail server.
I think TLS is no longer doing its job, which is why Jijo's mail server is now rejecting all my mail. How do I go about troubleshooting this?
Hmm. HANG ON A SEC. This is dodgy.
telnet localhost 10025 Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. 220 pd7mf1no.prod.shaw.ca -- Server ESMTP (Sun Java System Messaging Server 6.2-2.05 (built Apr 28 2005)) HELO sachachua.com
That's not the server I'm looking for! The port is supposed to be forwarding to mail.hosting.qsr.com.ph. I think Shaw may have just started transparently fiddling with its SMTP out.
That's not good. I don't know if I can find another way out, as I think Grad House or the university blocks port 25 out...
Stymied by the sudden breakage in my mail setup, I racked my brain for another way to get to the mail server in order to deliver my mail. None of the shell accounts I had on other systems were active, and none of the people I pinged were online.
I remembered that /etc/services was a list of well-known ports. If mail.hosting.qsr.com.ph was listening on another standard port, that would be a good place to find it. Searching this file for "smtp" turned up port 25 (smtp) and port 465 (smtp over SSL).
A quick check confirmed that port 465 was accessible from my computer even without tunneling.
All I had to do, then, was set up my mail system to use the new port.
I tried putting the port in directly. I also tried playing around with the configuration, but I couldn't find a clear tutorial.
I found stunnel along the way. Stunnel is a generic SSL tunnel for any network service, and it was really easy to set up. Here's my /etc/init.d/stunnel-mail based on http://www.technovelty.org/linux/tips/exim4ssmtp.html :
#!/bin/sh case "$1" in start) echo -n "Starting ssmtp tunnel " start-stop-daemon --start --quiet --exec /usr/sbin/stunnel -- -c -d ssmtp -r mail.hosting.qsr.com.ph:ssmtp echo "stunnel." ;; stop) echo -n "Stopping ssmtp tunnel " start-stop-daemon --stop --quiet --oknodo --retry 2 --exec /usr/sbin/stunnel echo "stunnel." ;; restart) $0 stop sleep 1 $0 start ;; *) echo "Usage: /etc/init.d/ssmtp-tunnel {start|stop|restart|reload|force-reload}" exit 1 esac
Then it was just a matter of adding new entries to my sasl_passwd file and regenerating the map.
Nothing like a good problem solved!
Random Emacs symbol: visible-frame-list - Function: Return a list of all frames now "visible" (being updated).
I accidentally deleted the second half of my workshop recording. Which is a pity, as it turns out you can get a fair bit of quality out of a plain recording.
Wow. The first one's not bad at all.
Random Emacs symbol: dump-emacs - Function: Dump current state of Emacs into executable file FILENAME.
I used my Sony Cybershot digital camera to take a video of my presentation at Democamp last night. The file weighed in at 400+ MB! After a bit of trial and error, I figured out how to use mencoder to crop to just me bouncing up and down and talking excitedly about Emacs. =) Here's the incantation I'm currently using:
mencoder -ss 111 -vf crop=275:300 mov07578.mpg \ -of mpeg -oac mp3lame -ovc lavc -o emacs.mpg
I might need to tweak it a bit more. Still, mencoder is fun!
