Configuring Salesforce Chatter
with an account in an org that doesn't have Chatter enabled results in an
unusable app. Upon start-up, it authenticates against the org, shows an error,
"Chatter is not enabled for this organization", then exits.
To restore Chatter to a state where it prompts for the org type, Default or
Sandbox, I had to remove the Encrypted Local Store
used by AIR apps.
$ rm -rf ~/.appdata/Adobe/AIR/ELS/sfdc-desktop.*

Today, I was trying to find email messages that I had sent which haven't had
any responses. My MUA is mutt and my mail is stored in Maildir folders. This
could be done with a fairly simple shell script using find and grep, but with
about 40,000 messages in the one folder I wanted to search, I was looking for
at least a slightly more elegant solution.
The idea is to find messages I had sent (to a specific recipient in this case)
and extract the Message-Id; then for each Message-Id, search for messages with
that Message-Id in their In-Reply-To or References header. If no messages are
found for this second search, we conclude that no response has been received.
I ended up writing a simple shell script that makes use of mairix, which indexes each
of the three fields I need to search. Unfortunately, mairix doesn't allow
searching the In-Reply-To or References headers directly, but does provide a
way to return all of the messages within the same thread as messages returned
as a search result. This allows us to restrict the number of messages searched
in the second pass to a single thread instead of the entire mailbox.
See the script below:

I added rel="nofollow"
support to the Blosxom writeback plugin. I use Doug Alcorn's version that supports
a blacklist and emails me when a new comment/trackback is posted.
Only one small change was required. I simply modified the writeback plugin to
prepend all href attributes with rel="nofollow".

To cover my state and federal taxes for last year and my estimated payments for
this year, as well as my IRA contribution, I scheduled a transfer from my ING
Direct account to my regular checking account for Monday. I actually had
enough in there to cover the taxes, but not the IRA contribution, so I wrote a
check for the contribution and mailed it on Monday so I could be pretty
confident that the ING transfer would be complete before the check was
presented for settlement. Despite the fact that the government was going to
be sucking a bunch of money out of my account, I was relieved to have my taxes
done and all the payments worked out.
One small problem: I accidentally scheduled the transfer from my
checking account to ING instead of the other way around, so on Monday my
checking account was emptied resulting in the rejection of three of the tax
withdrawals as well as a scheduled credit card payment, generating four NSF
fees, and my taxes not being paid on time.
I called ING to schedule the transfer of the mistaken withdrawal as well as the
original deposit I meant to make, and my other bank to ask that they honor
payments presented in the mean time. I hope that my IRA contribution check
clears or I may have to file an ammended tax return without the contribution
and pay more taxes plus penalties. What a disaster.

My post about the first night on my
Novafoam mattress still gets the most traffic on this blog (although a
homework assignment about the French health care
system has been remarkably popular the past month or so).
Every couple of months, I get an email asking about the mattress. Dale emailed
me this morning to ask how we like the mattress after sleeping on it for over
three years:
Hi,
In searching the web, I found your blog ("first night on..." on pinkhamster) on
shopping for a Novafoam mattress - now that your blog is more than three years
old, I'd like to hear an update if you could take a moment to let me know (or
add a posting and point me to it) as my wife and I are in need of a new
mattress and no better source than a longer-term customer...
Thanks,
Dale
I'm happy to report that we are still satisfied with our Novafoam mattress. It
hasn't lost its support, and it still very comfortable. One thing that I
didn't mention in the original post is that motion isn't transmitted laterally
much when your sleeping companion moves. It's much better than the bouncing
that happens on when sleeping on a cheaper spring mattress or an air mattress.
Having spent two nights on an air mattress a couple weeks ago reminded me how
much I like our mattress. I think we'll probably buy a King Novafoam mattress
when we move to a larger home.
p.s. This season of Penn & Teller's Bullshit! has an episode on mattresses and sleep aids.

Saleforce uses 15-character IDs as primary keys for every record. When
retrieving an ID over the API,
18-character case-insensitive IDs are returned. Generally, this doesn't cause
any problems because the 18-character version can be used anywhere the
15-character one is. One problem arises though when you are storing IDs in a
text field. In this case, you may need to convert a 15-character ID into its
18-character version. Salesforce provides a description of how
to perform this conversion.
Here is a PHP implementation of the algorithm.
function sf15to18($short) {
$chunks = str_split($short, 5);
$extra = '';
foreach ($chunks as $chunk) {
$chars = str_split($chunk, 1);
$bits = '';
foreach ($chars as $char) {
$bits .= (!is_numeric($char) && $char == strtoupper($char)) ? '1' : '0';
}
$map = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ012345';
$extra .= substr($map, base_convert(strrev($bits), 2, 10), 1);
}
return $short . $extra;
}

If you are trying to track multiple domains within the same Google Analytics or
Urchin profile, make sure you are using the same tracking library on all sites.
I was attempting to track a visitor from one site using urchin.js to another
using ga.js, and I spent a few hours trying to figure out why it wasn't
working.
It turns out that the cookie data is encoded differently in query string
appended to the url of the site to which you are passing it. With urchin.js
and __utmLinker(), the __utmz cookie is url-encoded, but not with ga.js and
._link(). Compare the two URLs below.
http://example.com/?__utma=1.1181041260.1202679736.1202679736.1202679736.1&__utmb=1&__utmc=1.0&__utmx=-&__utmz=1.1202680382.1.3.utmcsr%3DFake%2BSource%7Cutmccn%3Dbogus%7Cutmcmd%3Dclicky%2Bclicky&__utmv=-&__utmk=129628685
http://example.com/?__utma=1.1181041260.1202679736.1202679736.1202679736.1&__utmb=1.0&__utmc=1.0&__utmx=-&__utmz=1.1202680287.1.2.utmcsr=Fake%2BSource|utmccn=bogus|utmcmd=clicky%2Bclicky&__utmv=-&__utmk=54196648
The ga.js _initData() won't properly parse the __utmz data from the query
string in the first example. I hope this saves someone else some time.

I've created a new site at http://bookne.ws
that searches blogs and Google News for references to books in an
Amazon Wishlist.
It uses Amazon's
E-Commerce Web Service to find a wishlist
by name or email address, and to retrieve the list of books on a wishlist.
Then it uses Yahoo Pipes to search for news for each of the book titles and
sort the results by date. Finally, it takes the results and replaces the book
titles and authors with links to pages that will return results for an
individual book or author. It also uses Freebase, a sort of structured Wikipedia, to
retrieve a short description of on author pages where they exist.
Every page also provides an RSS feed of the results that are returned.
For example, if you use my wishlist of mostly economics books (which also
happens to be the default list used at the bookne.ws homepage), you might
see an except and link to an article
about Nassim
Taleb's Fooled by
Randomness, one of the books on my list.

Amazon has a new service called Unspun that makes it easy to create "best-of" lists.
People can vote on Amazon's site, and lists can be embedded in other web pages
so votes can be solicited elsewhere.
I've created two lists: Best
Living Economists and Best
Economics Books. For the economists list, I basically just put down the
economists whose blogs I read, and who I thought were especially good at Mises University. I
haven't finished my list of top econ books; it's harder than I expected.

If you work with people, you have probably received meeting requests from MS
Outlook/Exchange users. I used to add these to KOrganizer using korganizerIn,
but I stopped using KOrganizer a long time ago, and I've been pretty happy
using Google Calendar for a while. My goal was to add meeting requests to my
Google Calendar. The OpenSync library
provides the means for moving events between different calendar formats, and multisync-tools
provide a command-line interface to the OpenSync library.
Install and configure multisync-tools.
# apt-get install multisync-tools opensync-plugin-google-calendar opensync-plugin-file
$ mkdir ~/calendar
$ echo "text/calendar;~/bin/addCalendarItem %s; needsterminal;" >> ~/.mailcap
$ msynctool --addgroup file-google
$ msynctool --addmember file-google file-sync
$ msynctool --addmember file-google google-calendar
$ msynctool --configure file-google 1
Change the contents of the <path> tag.
<config><path>/home/dir/calendar</path><recursive>FALSE</recursive></config>
$ msynctool --configure file-google 2
Replace USER@gmail.com with your Google username and PASSWORD with your password.
Create ~/bin/addCalendarItem:
#!/bin/sh
echo loading $1;
cp $1 `tempfile -d ~/calendar`
msynctool --sync file-google 2> /dev/null
Now when you get a meeting request in mutt, you can view-attachments,
then view-attach (<Return>) on the meeting.ics attachment, and the
meeting will be added to your Google calendar. It's not perfect. No
acceptance notifications are sent. If you view a meeting request multiple
times, it will be added to the calendar multiple times. Sometimes the
synchronization hangs, and when you try it again, it detects conflicts between
what's in your calendar directory and your Google calendar, and you have to
tell it which to keep.
If I ever get the motivation, I might write a script to just add events using
the Google
Calendar API since I don't really need two-way synchronization.
Thanks to Trond for getting me started.
