Last weekend while Sarah was up in Canada for a spa weekend with her sister and her sister's other bridesmaids, I went to Saul and Ciera's
wedding in Three Rivers, California near Sequoia National Park. I flew into Fresno picked up a rental car and my GPS device navigated me to a restaurant with the wedding location no where in sight.
"No problem," I thought, "I'll just call someone with an Internet connection and..." I had no cell reception. What did people do before GPS, Internet, and cell phones?
A waitress in the restaurant pointed me down the road a bit to the wedding location which was outside overlooking a
river. Their wedding cake was made up like a mountain with two backpacks at the top and rope hanging down. Ciera's father married them and the ceremony was lovely. The music after included Code Monkey to which all the nerds were forced to get up and awkwardly dance.
Besides getting to see Ciera and Saul who I hadn't seen in quite a while, I got to see Daniil and Val, Vlad, and Nathaniel. Since
last I saw Daniil and Val they had a child, Katie who is very cute and in whom I can see a lot of family resemblance. The always hilarious Vlad,
Daniil's brother, was there as well with his wife who I got to meet. Nathaniel, my manager from Vizolutions was there and I don't know if I've seen him since I moved to Washington. It was fun to
see him and meet his girlfriend who was kind enough to donate her extra male to male mini-phono cord so I could listen to my Zune in the rental car stereo on the drive back.

previous post I mentioned an xsltproc like js file I made. As noted in that post, on Windows you can write console script files in
JavaScript, name them foo.js, and execute them from the command prompt. I later found that
MSDN has an XSLT javascript sample
which looks similar to mine, but I like mine better for the XSLT parameter support and having a non-ridiculous way of interpreting filenames. The code for my xsltproc.js follows. The script is very
simple and demonstrates the ease with which you can manipulate these system objects and all it takes is opening up notepad.
var createNewXMLObj = function() {
var result = new ActiveXObject("MSXML2.FreeThreadedDOMDocument");
result.validateOnParse = false;
result.async = false;

media keyboard microsoft wireless mce 2007 Jul 13, 8:30I bought an external backup drive a few weekends ago. I've previously setup a
Subversion repository so I decided to move everything into the repository and
then back it up. So in went the contents of all of my %USERPROFILE% and ~ directories with a bit of sorting and pruning. Not too much though given its much easier to dump in everything and search for
what I want then to take the time to examine and grade each file. What follows are the notes I took while setting this up. It takes me a bit of time to look up the help on each command so I figure
I'll write it all down here for the benefit of myself and potentially others...
Setting Up the Backup Drive For Linux
I first changed the filesystem on the drive to ext3. I plugged it into my USB2.0 port and ran fdisk:
sudo fdisk /dev/sda
Useful commands I used to do this follow mostly in order:
-
m
-
help
-
p
-
print current partitions
-
d
-
delete current partition
-
n
-
create new partition (I used the defaults)
-
w
-
write changes and exit
Then I formatted for ext3.
sudo mkfs.ext3 /dev/sda1
I made it easy to mount:
sudo vim /etc/fstab
# added line to end:
/dev/sda1 /media/backup ext3 rw,user,noauto 0 0
I setup the directory structure on the disk
mount /media/backup
sudo mkdir /media/backup/users
sudo mkdir /media/backup/users/dave
sudo chown dave:dave /media/backup/users/dave
After all that its easy to make a copy of the Subversion repository:
mount /media/backup
cp -Rv /home/dave/svn /media/backup/users/dave/
umount /media/backup
Next on the agenda is to add a cron job to do this regularly.
Subversion Command Reference
On a machine that has local access to the Subversion repository you can check out a specific subdirectory as follows using the file scheme:
svn co file:///home/dave/svn/trunk/web/dave%40deletethis.net/public_html
Note also that although one of my directories is named 'dave@deletethis.net' Subversion requires the '@' to be percent-encoded.
Other useful subversion commands:
-
svn help
-
help
-
svn list file:///home/dave/svn/
-
list all files in root dir of svn depot
-
svn list -R file:///home/dave/svn/
-
list all files in svn depot
-
svn list -R file:///home/dave/svn/ | grep \/$
-
list all directories
-
svn status
-
List status of all files in the working copy directory as in - modified, not in repository, etc
-
svn update
-
Brings the working copy up to date wrt the repository
-
svn commit
-
Commit changes from the working copy to the repository
-
svn add / move / delete
-
Perform the specified action -- occurs immediately
Setting up Windows Client for Auto Auth into SVN
When using an SVN client on Windows via svn+ssh its useful to have the Windows automatically generate connections to the SVN server. I use
putty on my Windows machines so I read the directions on
using public keys with putty.
putty.exe dave@deletethis.net
cd .ssh
vim authorized_keys # leave the putty window open for now
puttygen.exe
Click the 'generate' button
Move the mouse around until finished
Copy text in 'Public key for pasting into OpenSSH authorized_keys file:' to putty window & save & close putty window
Enter Key passphrase & Comment in puttygen
Save the private key somewhere private
pageant.exe
'Add Key' the private key just saved.
Checking out using Tortoise SVN
On one of my Windows machines I've already installed Tortoise SVN. Checking out from my SVN repository was really easy. I just right clicked in Explorer in a directory and selected "SVN Checkout...".
Then in the following dialog I entered the svn URI:
svn+ssh://dave@deletethis.net/home/dave/svn/trunk/web/dave%40deletethis.net/public_html/
Note again that the '@' that is part of the directory name is percent-encoded as '%40' while the '@' in the userinfo is not.
Windows Command Line Check Out
On my media center I didn't want to install Tortoise SVN so rather I used the
command line tool. I setup pageant like before the only
difficulty was getting the SVN command line tool to use putty. With the default configuration you can use the SVN_SSH environment variable to point at a compliant SSH command line tool. The trick is
that its interpreted as a backslash escaped string. So I set mine thusly:
set SVN_SSH=C:\\users\\dave\\bin\\putty\\plink.exe
The escaping solved the vague error I received about not being able to create the tunnel.
backup technical personal windows svn linux subversion 2007 Jun 7, 5:29The other day I had the best idea for my Wii remote. Clearly I should use it to control the rotation of Tetris pieces in my
N-dimensional
Tetris game Polytope Tetris. One of the
issues I described with Polytope Tetris is user input. Given a Wii remote the
user could rotate a piece through 3 dimensions in a manner that's much easier to adjust to than particular keys on the keyboard.
Anyway, I did a little
research into how this might work. I knew that the Wii remote used infrared for absolute positioning and
Bluetooth for everything else (LEDs, speaker, accels.) I bought a
Bluetooth adapter for my PC after realizing that none of my
computers had one already. I used
GlovePIE to ensure that my Wii remote could connect and successfully communicate with my computer.
GlovePIE is actually pretty cool -- it provides a simple script layer over the Wii remote to control things like your mouse.
Since Polytope Tetris is in Java I looked for and found a
Java library for operating with the Wii remote and a long
forum thread discussing its use. I then read up on
Bluetooth in Java. Apparently JSR 82 is the name of the standard that describes the API a Bluetooth stack should expose
in Java. That is, to get Bluetooth working in Java one needs an additional package for Java that actually implements the Bluetooth Java API. This package would depend on the system so I suppose I
can't fault Sun for not including it... Where to find such a package? I found a
comparison list of implementations and tried the ones
that support javax.bluetooth.
None of them worked for me because none can address USB devices it seems or they cost money and I couldn't get the trial version working. I also tried
bluesock (not listed on the previous list) which seemed promising and could produce an address for my Wii remote as a connected device but couldn't use
that address.
And I thought that after I found the Wii remote Java library it would be easy... Oh well...

shopping clothing gadget shoulder holster bag 2007 Apr 17, 11:45Opera (
the fifth most popular web browser) has a new feature named
Speed Dial (video of it in action). Whenever you open a new tab you get your Speed Dial view which consists of nine thumbnails of user-settable
pages. Its like a quick-favorites that appears every time you open a new tab. I think this is a neat idea and was considering how I might do that in IE7. The following is my hack-y and ugly but no
coding required version of Speed Dial for IE7. I like my hack and I'm about to expound upon it in unnecessary detail so skip to the last paragraph if you're afraid of losing interest.
By default in IE7, whenever you open a new tab you navigate to 'about:Tabs'. As noted in wikipedia the result of
navigation to 'about:Tabs' is determined by values in the registry. Specifically, values in the key in
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AboutURLs". Usually this fact is exploited by
malicious software to hijack
"about:blank" and show you ads but we can hijack it too in order to display our Speed Dial-ish page.
Of course since this is a code-less hack we've got limited options on what to change 'about:Tabs' to display. It should have the following requirements.
- Something local so that our 'about:Tabs' doesn't disappear when we go offline and so that its relatively fast.
- The user should be able to modify its content.
- Show links that the user uses.
- Show thumbnails of those links
- Provide easy to use drag and drop interaction and generally look cool.
Now, I use del.icio.us which allows me to store all of my favorites online and which provides RSS feeds that list my saved links. New in IE7 is an
RSS platform that will, among other things, cache RSS feeds locally. So, by pointing
about:Tabs to my del.icio.us feed 'http://del.icio.us/rss/sequelguy/quickreference' I get (1) from IE7's RSS support, and (2) and (3) from del.icio.us. Of course requirements (4) and (5) are missing
but hey, I said this was ugly.
In summary, if you change the registry value "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AboutURLs!Tabs" to point to an RSS feed of your favorites you can get a hack-y version of Opera's
Speed Dial. I should note that although its referenced on pages such as wikipedia changing your 'about:Tabs' URI in the manner I describe is not documented and not supported by Microsoft. There could
be all kinds of horrible repercussions from this change of which I'm not aware. Yeah, actually you know what? Forget I said any of this. Pretend I never wrote it...

I just saw this on
another user's delicious links:
a link to ESV search that's
tagged with, among other things, "shortcut:esv". When viewed on del.icio.us there's a text box that lets you search using that link. I hadn't seen this before, but it seems pretty cool and I'm
surprised I hadn't seen it previously. A delicious post with such a tag ends up looking like the following:
I tried searching for information on this and I've found
other delicious users doing the same thing,
but nothing about the tag itself. If you know any information especially official information from del.icio.us itself please post links in reply to this post. So without further preface here's what
I've learned about the del.icio.us shortcut tag.
How-to
To get a search box in your del.icio.us links make a post that satisfies the following requirements:
- One of the tags must begin with the text 'shortcut:'. You can have more text following that in the tag if you like but it must at least start with 'shortcut:'.
- The 'url' you post must be a shortcut url rather than an actual URL. It must contain a '%s' with a lowercase 's'. When you enter text into the textbox on the del.icio.us page the text will
replace the '%s' after being percent-encoded. For example 'http://www.google.com/search?hl=en&q=%s' is the shortcut url for Google and if you type 'foo bar' into the textbox the URI you will
navigate to would be 'http://www.google.com/search?hl=en&q=foo%20bar'.
Complaints
This is neat but I do have a few complaints:
- The text from the textbox is percent-encoded before replacing the '%s'. Most sites use application/x-www-form-urlencoded
which encodes spaces as '+' rather than '%20'.
- The shortcut url format seems to be taken from Mozilla's Firefox Custom Keywords. Its a shame it wasn't based on something more
adaptable like the OpenSearch URL template syntax.
- A '%s' in the url means technically what you're submitting to del.icio.us isn't a URI as defined by the standard.
- Allowing text after 'shortcut:' means you can't look at all of a user's shortcut using this tag.
The next step is to create a tool to sync my
IE7 search providers with my shortcuts saved to delicious...
