IPv6 address syntax consists of 8 groupings of colon delimited 16-bit hex values making up the 128-bit address. An optional double colon
can replace any consecutive sequence of 0 valued hex values. For example the following is a valid IPv6 address: fe80::2c02:db79
Some IPv6 addresses aren't global and in those cases need a scope ID to describe their context. These get a '%' followed by the scope ID.
For example the previous example with a scope ID of '8' would be: fe80::2c02:db79%8
IPv6 addresses in URIs may appear in the host section of a URI as long as they're enclosed by square brackets. For example:
http://[fe80::2c02:db79]/
. The RFC explicitly notes that there isn't a way to add a scope ID to the IPv6 address in a URI. However a draft document describes adding
scope IDs to IPv6 addresses in URIs. The draft document uses the IPvFuture production from the URI RFC with a 'v1' to add a new
hostname syntax and a '+' instead of a '%' for delimiting the scope id. For example: http://[v1.fe80::2c02:db79+8]/
. However, this is still a draft document, not a final
standard, and I don't know of any system that works this way.
In Windows XPSP2 the IPv6 stack is available but disabled by default. To enable the IPv6 stack, at a command prompt run
'netsh interface ipv6 install'. In Vista IPv6 is the on by default and cannot be turned off, while the IPv4 stack is optional and may be turned off by a command similar to the previous.
Once you have IPv6 on in your OS you can turn on IPv6 for
IIS6 or just use IIS7. The address ::1 refers to the local machine.
In some places in Windows like UNC paths, IPv6 addresses aren't allowed. In those cases you can use a Vista DNS IPv6 hack that lives in the OS
name resolution stack that transforms particularly crafted names into IPv6 addresses. Take your IPv6 address, replace the ':'s with '-'s and the '%' with an 's' and then append '.ipv6-literal.net'
to the end. For example: fe80--2c02-db79s8.ipv6-literal.net
. That name will resolve to the same example I've been using in Vista. This transformation occurs inside the system's local
name resolution stack so no DNS servers are involved, although Microsoft does own the ipv6-literal.net domain name.
MSDN describes IPv6 addresses in URIs in Windows and I've described IPv6 addresses in URIs in IE7. File URIs in
IE7 don't support IPv6 addresses. If you want to put a scope ID in a URI in IE7 you use a '%25' to delimit the scope ID and due to a bug you must have at least two digits in your scope ID. So,
to take the previous example: http://[fe80::2c02:db79%2508]/
. Note that its 08 rather than just 8.

- A History Channel program had a reenactment of a 1920's archaeologist discovering a stone tablet, sending the tablet to a warehouse, etc. all behind the voice over giving the dry facts. The
reenactor hammed it up a bit and I would have rather had clips from Indiana Jones in the background. If they're already not showing me the archaeologist who discovered the tablet, they may as well
show me one who will be entertaining.
- There are many parodies of the Get a Mac ads and so when I saw a UK Get a Mac ad I payed attention to see what the joke was. I was
disappointed by the 'parody' because it was a conventional Get a Mac ad with different actors. Apple localized their Get a Mac ad campaign in this fashion in the UK and in Japan. I've got a
playlist of the US, UK, and Japan's version of the Piechart ad. Ranking the lovable bumblingness of the PC I give the order
UK, Japan, then US and ranking the sumgness of the Mac I give the order UK, US, then Japan. But don't take my word for it, view
the ads for yourself.

Yahoo Pipes lets users generate an RSS feed altering service that runs on Yahoo's server using a GUI. This is very different from Microsoft's Popfly which allows users to component-ize and share javascript utilities that run client side on a webbrowser. Both have the awesome power of buzzword associations
like 'Web 2.0' and 'Mashup' but in my mind Yahoo Pipes is for server side RSS feed modification and Popfly is about client side javascript webpages. And neither will allow me to run an arbitrary

the route from Toronto, to Burlington (for the wedding), and then Niagra.
In Toronto we visited the
CN Tower, the
ROM, and the
Bata Shoe Museum. We generally acted like tourists walking around taking photos of things, putting on sun block, and not saying 'eh'. But we could have been worse
like the drunk American college students in front of us in line for the CN Tower asking the guide if the CN Tower is taller than the Stratosphere in Las Vegas. We stumbled upon the
Toronto Outdoor Art Exhibit which was really interesting. Sarah in particular recalls the cute stuffed animal
monsters.
After Toronto we drove to Burlington where Palak and Meghal's wedding would take place. We got up early and made it on time to the wedding which was
lovely. I hadn't attended an Indian wedding previously so it was a new experience for me. During the ceremony the child in front of me kept peeking over her parent's shoulder and staring at me. It
lasted all day with a break after lunch during which we drove around and experienced small town Ontario. After the break cousins performed dances for Palak and Meghal and then we all danced the night
away until the wee hours.
In Niagra we stayed in a hotel room with a falls view which was lovely. We went on the
Maid of the Mist tour that takes tourists
right up to the falls in a boat and drenches them. We also went on the
Behind the Falls tour which was not as fun. In both we are
given rain coats which are essentially glorified plstic trash bags. For dinner we ate in the hotel restaurant which had a lovely view of the falls. At night the falls are lit up in various colors
with gigantic lights.

other office hacks some dedicated coworkers and I decided to do something to my manager's office.
While gone we knew my manager, Venkat, was getting into meditation. My coworker Vishu had the excellent idea of easing Venkat back into work by making his office
better suited for meditation. To start with, we updated his nameplate with an
Om.
Next we emptied his office of anything that could distract him from meditation and replaced it with a yoga mat. Of course I left a copy of the specification
for the remodel in his office.

resource tools and then I used them to
overwrite msxml3's
XML source view. In this update I've added support for the XPointer Framework.
This time around I've started to add support for the
XPointer Framework to my
XML source view and
I've added
installation instructions. The framework consists of a series of pointer segments each of which has a scheme name followed
by data in parenthesis. For example 'scheme1(data1)scheme2(data2)scheme3(data3)'. A pointer segment resolves to a portion of the XML document based on the data and the scheme name. The whole pointer
resolves to the first segment that successfully resolves. That is, from the example, if scheme1 resolves to nothing and scheme2 resolves to something then that's used and scheme3 is ignored. In
addition to the framework I've added support for the
xmlns scheme which binds namespace prefixes to a namespace URI and the
element scheme which is a simple way to resolve to particular elements in an XML. I also have limited support for the
xpointer scheme the content of which is resolved as an
XPath with some extra functions (which I don't support --
hence the limited). I've also thrown in schemes for the two
SelectionLanguage values supported by msxml3.
Next time I might try to support the xpointer functions that aren't in xpath using
msxml script. But I think I'm losing steam on
this project... we'll see.

Carissa and Elijah's wedding Sarah and I went to San Francisco. We drove in, well Sarah drove anyway, still in
the PT Cruiser Sunday morning and checked into our hotel,
Hotel Diva. I was originally concerned that I wouldn't fit in as I don't really consider myself a
diva, however the hotel was cool. They have Internet rooms setup in various themes, the front desk is always staffed, our room had a very modern look, and when we entered the flat-screen over the
front desk was playing an episode of Aqua Teen Hunger Force.
We walked around a bit before going to the
SF Museum of Modern Art. There was a Picasso exhibit at the time
which we could see for only $3 more. It felt kind of wrong like my ticket was super-sized. I think the most memorable piece I saw was
three white
panels which consisted of three blank panels. Art. Sure. After that Sarah wanted to see the giant Hello Kitty store she had heard of from her sister. We ended up going to the Westfield Shopping
center which has a disappointingly average sized Hello Kitty store. Apparently the giant one is gone. That night we went to
First Crush for dinner. I had a
flight of wine which consists of three one-third sized glasses of various but complimentary wines. It was a great restaurant in terms of food, drink, atmosphere and service.
The next morning we were even more the tourists when we went down to Fisherman's Wharf and Pier 39. We visited the famous wax museum and purchased multiple
pounds of taffy. On the way back to the Oakland airport we got to experience a little traffic as part of
the
580 freeway had collapsed the morning we arrived and was still under repair on our way out. We survived of course and I think the trip went rather well.

coming and sometimes from credible sources. After the article I saw tonight I thought I should go back and put together the various articles I've read on this topic. Bees may be disappearing due to
pesticides,
new organic pathogens,
genetically modified crops,
mobile
phones, or
climate change. Apparently,
the US hasn't been keeping accurate counts of its
bees so we don't know the extent of the situation. There's an
interview with Maryann Frazier, M.S., of the Dept.
of Etymology at Penn State and a
congressional hearing on the matter.
I know this is all very serious and could signal the end of our ecosystem as we know it, but I can't help throwing in the following links as well. The bees could be
hiding in this Florida couple's kitchen. Or perhaps they're laying low while being
trained by the government to fight terrorism. Or
they're hiding in extra dimensions that we mere humans can't perceive (I'm fairly certain that's what this
article is suggesting. Really. Read it. Seriously. Its awesome.)

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...
