Removing a Version from ClearCase UCM

Here's a good blog about removing a version of a file from ClearCase UCM:

My First (Semi) Manual!

I got the track stand down pretty good, so I began trying to manual. Normally, I would jerk the bars up as hard as I could to try getting over an obstacle, but I've realized that really isn't the best way.

So, I got a copy of Mastering Mountain Bike Skills and began reading (it's a very good book). Between that and the author's website www.leelikesbikes.com, I finally started to "get" just how to do a manual.

These posts at Lee's blog also helped immensely:

• How to Manual Again
• Tallness is no Excuse
• Manuals for Small Riders

Between those posts, the responses to the posts, and the book, these are the tips that helped me the most:

1. I lowered the seat to practice. This let me shift my hips back much more easily. I'll practice with my seat at my "standard" XC height once I get this down.
2. Really focused on using the "third brake" (ie, practically scratching your butt with the rear wheel because you shift your hips back so far). Basically, Lee said you probably aren't shifting nearly as far as you think you are, so I really tried to "over-exaggerate" the entire motion (my over-exaggeration was probably closer to the "real" motion).
3. Finally, really pushing forward with my arms and driving my legs down and forward.

The first time the wheel came up, it felt like some Jedi was lifting the wheel with the Force! It was a very strange feeling since I was used to muscling it up. The wheel just needs to pop up a bit before your shifted-weight takes over. The more you pre-load and the faster you push yourself backwards, the faster it happens.

So far I have bailed off each time it gets up, but I'll get used to the feeling soon enough and learn to control it. I have found that once it comes up to a certain height I start pulling myself up. I just need to let it happen. It seems like minor shifts of the hips should stabalize it, as well as a few pumps with the legs (you can see the kid to that in this video):

Once I'm better at this, I can finally begin working on some nice, high bunny hops!

ClearCase UCM Triggers

I didn't realize this page existed on the CM Wiki. Unfortunately the links seem to be broken... If anybody reads this and knows why, please let me know. I'll post if I find out any info.

Google Chrome Proxy Server Setup

Google Chrome uses IE's Proxy settings... However, you can force it to be something different using the "--proxy-server=XXXXX" switch. Or, just use "--proxy-server=" to use no proxy.

This is really nice, because now I can set up two Google Chrome shortcuts - One to fire up Chrome at work and use the proxy, and the other with the "--proxy-server=" switch so I can use Chrome at home!

I like that better than going into the settings of FireFox each time I start it up (I haven't found a proxy plugin that works well yet...). Maybe FireFox has a similar switch?

Rear Derailleur adjustment

There's some time of black magic behind adjusting the rear derailleur. It's as hard as trying to remember how "derailleur" is spelled!!! When I read some tips on adjusting it, it seems easy. About 30 minutes later, my chain is all over the place on the rear cassette.

Anyways, this seems like about the best article I've found so far. At least my chain shift through *most* of the gears now!!

*** After some more reading and monkeying around, I realized it isn't quite as hard as I thought... I just wasn't getting it for some reason at first...

Mountain Bike Technique - track stand

A track stand is something I really need to practice:

More related videos here (the "Beginner" section is kinda funny to watch... The lady doing the stuff is just strange)

The advanced technique also describes bunny hopping in good detail.

After that, I'll work on these:

Temp file in Perl

Use the following to generate a temporary file in Perl:

use File::Temp;
my $fh = tempfile;

print $fh "temp data";

Also, this finds the directory of the Perl script being executed:

use FindBin;
my $program_dir = $FindBin::Bin;

This, and some other useful Perl things, are found here:
