Muni Ride Log, entry 18: Stevens Trail

Muni Ride Log – Stevens Trail, Colfax, CA (another link to info about it). I started using the iPhone app “iMapMyRide“. It dumps things back to a website and generates a nice map. Unfortunately, some data points seem to get lost, and it shows straight lines. The ride really took 1:35 mins (roughly), which is right, but I don’t think the mileage is correct. Most sites say 4.5 miles each way, and 9 miles total, which sounds more correct given the time. I rode it on the geared 24 KH muni; mostly in the high gear on the way out... [read more]

HDR vs non HDR

HDR images can really pull out some highlights that you normally wouldn’t see. Here’s a comparison of an HDR generated by taking a single RAW photo and exporting 3 different exposures from Aperture. I then combined them in Photomatrix. Original: Generated HDR, including some cropping and alignment: Photo also on flickr. To me, the HDR looks more real, and feels like what I was seeing at that time. The picture is Louise’s choir group, the Choral Project at a really cool St Dominics Church in San Francisco that had huge ceilings and amazing flying butresses that were apparently added after...

Matching Geared KH 24 Mountain Unicycles

Louise and I have (somewhat) matching Geared KH 24 Mountain Unicycles: Mine’s rim has horizontal stripes: While Louise’s is a candy-cane:     Unfortunately, the paint job on mine got warn away after one day of riding at Northstar (lots of drops on rocks):

Save a tree

I don’t like the idea of killing a tree every year just so we can stick it in our house and put presents under it, so I convinced louise to let us get a live tree. So, instead of removing a tree from our ecosystem, we will be planting one back into it. Imagine how many trees we could plant if everyone started doing this. If you live in a city, you can still take your tree to a nearby park or forest and set it free after the holidays.

Project Hutchinson: Upstairs Built-ins

Here’s the big pile of maple and poplar that I got for the project: Building the face frame was super fast and easy to do with pocket jointery:

Project Hutchinson: Tablesaw outfeed table

I wanted to start work on my built in dressers for the upstairs, but first I needed an out feed table for the tablesaw. I wanted something that doubled as a work space, and added some additional storage. I also wanted a built-in sanding table, but I decided to do that another day. So, using some pocket hole joints, old 2x4s and 2x6s ripped clean and glued together, I made a really rock solid outfeed table. The top is two pieces of 3/4″ MDF glued and screwed together, with counter top stuff on the top to protect it and add... [read more]

Honduras Pictures

Some pictures from Honduras, hosted on Flickr (one of too many photo sharing sites that I use) HDR picture of the dock in Roatan, Honduras. This picture makes you think. You want to turn your head, since the horizon is not level, but at the same time it also looks correct, since part of the pier is horizontal to your reference. At the same time, it fades slightly to the background. Interesting Palm tree Black and White flower

Couple pictures from SD Muni Weekend

I only took a few pictures. Here they are: Cody doing a kick flip trick off the ramp at Mile’s house. Max, reaching the top. Amazing. Simply amazing! Max trying street moves. A suspension unicycle with a disk brake. It felt a little too coshy when I tried riding it, but I didn’t give it a real go.

Diving, Roatan island, Honduras

Louise and I went with Ken, Gabrielle, Mark and Michelle to Honduras to do some diving. We are staying at the Luna Beach resort and have done two days of diving so far. Today was the best day for diving– tons of fish! My highlights included seeing a grouper fish with half a trumpet fish sticking out of it’s mouth.

Geared 24″ Mountain Unicycle Riding

I finally got a geared hub for my 24″ Mountain Unicycle (muni) and gave it a ride last weekend. What a treat! The thing is blastingly fast. I rode a 6-7 mile loop in the Soquel Demonstration Forest called “Braille Trail”. It has a huge climb; most people walk it. I powered up it with a few lame dismounts (mainly due to me not being as fit as I usually am). I didn’t notice the extra weight in the hub at all! Riding down the single track was a blast; I tried to keep it in high gear as much... [read more]

Iphone art

Some crafty iPhone art. Taken quite a while ago and not altered.

The next big project…

….built-in “knee wall” dressers for the upstairs! Here’s a couple of pictures from SketchUp. I will give anyone the models, if they are interested in seeing how I designed them. I purchased a bunch of wood from aura hardwoods yesterday, and I’m hoping to start building tonight!

It’s a happy and a sad day.

I’ve known all along that Obama would win. I’m glad I was right! I’m sad that Prop 8 passed. Everyone should consider it a sad day for America when we start removing people’s rights and start discriminating against people. Saying two people can’t get married is discrimination. Maybe some day we will look back and realize our mistakes that we are making. We’ve made them before, and we know they were wrong. Women not being able to vote. Slavery. It was wrong for the morman church to back Prop 8 — especially considering most of the funding came from outside... [read more]

MOVIE: California Mountain Unicycle Weekend 2008

I made a quick movie for the “California Mountain Unicycle Weekend 2008” in San Diego. Here it is! High quality, requires QuickTime or some other H264 decoder: And for you people who like YouTube, horrible quality:

Cal Muni Weekend 2008

Last weekend I drove down my Prius to San Deigo for the annual “California Mountain Unicycle Weekend”. Nathan put some pictures up here: CMW 2008 Here’s me on the top of one of the rides: <pictures coming later> Hans also took a picture of me pedal grabbing:

Project Hutchinson: Upstairs drywall and windows

I’ve been working quite a bit on our upstairs remodel project. I removed an old closet, and installed lighting in the ceiling. This helps tremendously with the look and feel of the room; it was always dark and shady, mainly because there was no built-in lighting. I also framed the wall in preparation for a door and drywall: I removed the old drywall on the side. I’m planning on building built-in dressers. The back window was a single half-triangle. It look completely out of place and asymmetric, and because the windows didn’t open, it would get really hot and stuffy... [read more]

Wedding Boxes

I recently went to the weddings of a few of my friends. Last weekend Tom and Nancy had a “Wedding Camp” celebration, and two weeks ago Andy and Irene got married in their barn. Both weddings were amazing, and Louise and I were very happy to be there with our friends. In the pursuit of avoiding standard gifts, I decided to employ my woodworking skills and make them some boxes out of “nice” wood. Here’s some pictures of the building process. I used cocobolo wood for the top; it is an exotic hardwood. I try to avoid exotic woods for... [read more]

San francisco uni ride

Right now! 40 miles


I got a new video game for the Mac – spore! I really wanted to give it a try last night, but my DVD drive stopped working on my MacBook Pro. Luckily, there are known hacks posted on the web for how to turn on the “Remote Disk” sharing that was added for the MacBook Air. This let me install it at working using one of the DVD drives on one of my other machines. I would have done it at home, but the two other Macs at home are still PPC running Tiger.

Why the API? NSTableView -preparedCellAtColumn:row:

I think I’ll do a few articles on why certain API was introduced in Leopard. I’ll start with one of the new methods in NSTableView: /* Returns the fully prepared cell that the view will normally use for drawing or any processing. The value for the cell will be correctly set, and the delegate method 'willDisplayCell:' will have be called. You can override this method to do any additional setting up of the cell that is required, or call it to retrieve a cell that will have its contents properly set for the particular column and row. */ - (NSCell...

Cocoa programmers: avoid writing to the user defaults when you don’t need to

[Edit: ecto ate this post, so I’m typing it in again!] I discovered that a lot of applications will unnecessarily write to NSUserDefaults. This causes your app to hit the disk when it shouldn’t, and is a slight performance penalty. AppKit is also susceptible to this problem; if you hit cmd-O to bring up the open panel in any application, you will see it writing things to the user defaults, when it probably doesn’t need to do so. I’m working on fixing that, and you should to! So, how do you do it? It is easy — just add a... [read more]
