The new name reminds me of the show Friends. Also, I hope they get a new favicon - I don't enjoy the stretched 'b' nor its color scheme.
PowerShell gives us a real CLI for Windows based around .Net stuff. I don't like the creation of a new shell language but I suppose it makes sense given that they want something C# like but not C# exactly since that's much to verbose and strict for a CLI. One of the functions you can override is the TabExpansion function which is used when you tab complete commands. I really like this and so I've added on to the standard implementation to support replacing a variable name with its value, tab completion of available commands, previous command history, and drive names (there not restricted to just one letter in PS).
Learning the new language was a bit of a chore but MSDN helped. A couple of things to note, a statement that has a return value that you don't do anything with is implicitly the return value for the current function. That's why there's no explicit return's in my TabExpansion function. Also, if you're TabExpansion function fails or returns nothing then the builtin TabExpansion function runs which does just filenames. This is why you can see that the standard TabExpansion function doesn't handle normal filenames: it does extra stuff (like method and property completion on variables that represent .Net objects) but if there's no fancy extra stuff to be done it lets the builtin one take a crack.
Here's my TabExpansion function. Probably has bugs, so watch out!
function EscapePath([string] $path, [string] $original)
{
if ($path.Contains(' ') -and !$original.Contains(' '))
{
'"' $path '"';

function PathRelativeTo($pathDest, $pathCurrent)
{
if ($pathDest.PSParentPath.ToString().EndsWith($pathCurrent.Path))
{
'.\' $pathDest.name;
}
else
{
$pathDest.FullName;
}
}
# This is the default function to use for tab expansion. It handles simple
# member expansion on variables, variable name expansion and parameter completion

I finally replaced my old regular cell-phone which was literally being held together by a rubber band with a fancy new G1, my first Internet accessible phone.
I had to call the T-Mobile support line to get data added to my plan and the person helping me was disconcertingly friendly. She asked about my weekend plans and so I felt compelled to ask her the same. Her plans involved replacing her video card so she could get back to World of Warcraft and do I enjoy computer gaming? I couldn't tell if she was genuine or if she was signing me up for magazines.
I was with Sarah in her new car, trying out the phone's GPS functionality via Google Maps while she drove. I switched to Street View and happened to find my car. It was a weird feeling, kind of like those Google conspiracy videos.
The phone runs Google's open source OS and I really enjoy the application API. Its all in Java and URIs and mime-types are sort of basics. Rather than invoking the builtin item picker control directly you invoke an 'intent' specifying the URI of your list of items, a mime-type describing the type of items in the list, and an action 'PICK' and whatever is registered as the picker on the system pops up and lets the user pick from that list. The same goes if you want to 'EDIT' an image, or 'VIEW' an mp3.
I wanted to replace the Google search box gadget that appears on the home screen with my own search box widget that uses OpenSearch descriptors but apparently in the current API you can't make home screen gadgets without changing parts of the OS. My other desired application is something to replace this GPS photo tracker device by recording my location to a file and an additional program on my computer to apply those locations to photos.
Netflix has recommended three party movies over my time with Netflix and if you're OK with movies featuring sex, drugs, rock&roll (or techno) as almost the main character then I can recommend at least The Boys and Girls Guide to Getting Down.
24 Hour Party People is based on the true story of Tony Wilson, journalist, band manager, and club owner (not all at once) around the rise of punk and new wave in England. Like many true-story based movies it starts off strong and very interesting but gets very slow at the end like the writers got bored and just started copying the actual events. Unless you have some interest in the history of music in the 80s in Manchester I don't recommend this movie.
Human Traffic is fun and funny following a group of friends going out for a night of clubbing and partying. I had to get over seeing John Simm as not The Master from Doctor Who but rather as a partying youth. It felt like it was geared towards viewers who were on something like the totally odd techno musical interludes with the characters dancing for no apparent reason. Otherwise the movie was good.
The Boys and Girls Guide to Getting Down is done in the style of an old educational movie on the topic of clubbing and partying. It sounds like a premise that would get old but they do a good job. While demonstrating drinking and driving they have scientists push a mouse around in a toy convertible. Enough said. It was funny and I recommend it.
I just upgraded to the Zune 3.0 software which includes games and purchasing music on the Zune via WiFi and once again I'm thrilled that the new firmware is available for old Zunes like mine. Rooting around looking at the new features I noticed Zune Badges for the first time. They're like Xbox Achievements, for example I have a Pixies Silver Artist Power Listener award for listening to the Pixies over 1000 times. I know its ridiculous but I like it, and now I want achievements for everything.
Achievements everywhere would require more developments in self-tracking. Self-trackers, folks who keep statistics on exactly when and what they eat, when and how much they exercise, anything one may track about one's self, were the topic of a Kevin Kelly Quantified Self blog post (also check out Cory Doctorow's SF short story The Things that Make Me Weak and Strange Get Engineered Away featuring a colony of self-trackers). For someone like me with a medium length attention span the data collection needs to be completely automatic or I will lose interest and stop collecting within a week. For instance, Nike iPod shoes that keep track of how many steps the wearer takes. I'll also need software to analyze, display, and share this data on a website like Mycrocosm. I don't want to have to spend extreme amounts of time to create something as wonderful as the Feltron Report (check out his statistic on how many daily measurements he takes for the report). Once we have the data we can give out achievements for everything!

Carnivore Eat at least ten different kinds of animals. |

Of course none of the above is practical yet, but how about Delicious achievements based on the public Delicious feeds? That should be doable...
I want to once again profess my love for the Wii's Virtual Console. Sarah and I recently finished playing through the first three Zelda games. Although I'd played a bit of the first two I never had a Nintendo as a kid and so unlike Sarah this was my first time completely playing through Zelda I & II. What people say about Zelda II is true... its all so true. And on the flip side I have fond memories of beating the third Zelda game which Sarah hadn't played.
In hilarious Zelda related news, a friend from work's husband posted the following blog post concerning their son named Link.
Last weekend after Saul and Ciera's wedding, I drove up to Pat, Grib, and Jesse's
house to which I hadn't previously been. I got in late and they'd just finished a UFC party. The next day Grib had to travel for work but the rest of us met Scott and Nicole, Jesse's girlfriend at
a place for breakfast. After that we went back to their place for some Rock Band which I hadn't played previously and Pat took the opportunity to show off his real life musical skills on the banjo.
This weekend, Jesse and Nicole are up visiting Seattle. On Friday, Sarah and I met up with them at the BluWater Bistro in Seattle which sits right on Lake Union. The view was nice although difficult to see from our table and overall I like the sister
restaurant in Kirkland better. They were both short visits but it was fun to see people again.
