Warships in San Francisco Photos

I managed to make my way up to San Francisco and see both the USS Bunker Hill and the Varyag. Unfortunately, there was a mixup about how long Russians were giving tours of the ship. Instead of going to 3 pm, they stopped at 1 pm. However, I did get some decent photos of the ship from the pier. For more detailed shots, I suggest you view the Chronicle’s pictures of ship. I did manage to take a tour of the Bunker Hill. We mainly stayed on the outside of ship, seeing the fore and aft vertical launch systems, the helicopter hanger, and also the bridge. About 350 crew members are on board, and about 40% of those are female. In 2008, the ship was the first Ticonderoga class cruiser to underwent an upgrade to its fire control systems, that allowed (in addition to other things) the ability of both the fore and aft 5 inch guns to be targeted independently. On of the new roles for the Bunker Hill is ballistic missile defense, and the ship is of the same type that recently shot down a satellite.

It was very cool tour, and look forward to the next San Francisco Fleet Week (October 7 – 12).

Flickr user Kyle Mizokami has some great shots from tours of both the Varyag and Japanese ships that were in town.

Penalty Cards

The World Cup is on. The US played its first match against England, and didn’t lose. I thought England had the “White Pelé.” He must have been hurt, because I didn’t see him out there. I only saw some pudgy bald guy. (Zing!) All I want is for the US will advance. Although, winning a game in the knock out rounds would be wonderful.

I love the idea of FIFA. They’re the anti-NCAA. (Fuck you, and go die in a fire NCAA.) I love the idea of promotion and relegation, where entire teams move up and down.1 I love the idea of having the winners of the different national professional leagues champions play each other.3. I even love, the subject of this post, penalty cards. They just look cool, and I love how they carry over during tournament play.4

I was looking at the history of penalty cards, and learned that they are a relatively recent invention. They date back to only 1970, and were quickly adopted by other sports. What really surprised me though, is that the iconic yellow and red, aren’t the only colors.

Apple Stickers

Vinyl stickers for MacBooks isn’t new. Etsy lists 1075 results. Of course many of them aren’t that good, but I do like the ones that integrate the laser cut apple in a clever way, like Moses on the Mount from above.

A while back, I thought about laser etching my laptop. I thought about placing the apple in the center of the Aztec calendar. Ultimately, I decided against it because there just isn’t enough room to really show what the motif is.

The Lynching of Mario

Mario, was a recent Italian immigrant, just trying make a living cleaning drains and fixing leaking pipes. No one paid much attention to him at first, but as the number of recent arrivals from Italy increased, tensions in the community grew.

On that fateful Saturday, a rumor spread that Mario had been caught trying to force himself on one of the town’s beautiful blonde maidens, Peach. Gathering clubs, the townspeople gather outside the small cottage that Mario shared with is brother, and demanded Mario to be sent out. When they refused, they broke through the door, and beat Mario’s brother so hard that he remained in the hospital for a week and almost died.

Mario was dragged from his home, and hanged in a near by tree. As hung there, slowly strangling, men and children would beat him until he died, and then continued to beat him until his body broken and torn.

After the lynching, doubts about the rumor began. Some even say that the rumor was started by an rival plumber with a vendetta. The truth is now lost.

Crappy Coffee Table Concluded

So we got a real coffee table of Craigslist for free. It’s nice, much better than this thing. I still went ahead and made the table though. There was no real reason not to, since we can find something to use it for. I give it a C in high school shop. I talked to my dad, and put it together with pocket screws using a Kreg Jig Jr kit. I tried using the right angle clamp, but I never got it to work. Whenever I’d lock it down, it would pull out of the pocket hole just enough to slide down, destroying the flat inner surface so you couldn’t put it back in the same hole. (My dad gets the clamp to work, but I never did.) If I had to do it over again, I would have gotten just a normal corner clamp.

I don’t really like it, but I guess it’s okay for being made out of scraps. I just wish I paid more attention when put the pocket holes in.

It’s heavy, and it’s square. I’ll give it that.

Crappy Coffee Table

A couple of months ago Ming and I decided redo the closet in the bedroom, since it was falling apart. We replaced the rod, and was going to replace the bent shelf with a new shelf long shelf, and then add some side shelves. So we went down to Home Depot and bought one of those crappy particle board covered in white melamine. Unfortunately, we had the guy cut the side shelves an inch too narrow, and left the long board way too wide. (Lesson: Always bring a ruler, and know exactly how big you’re talking about.)

While we were able to hack together something to use side shelves, we were left with three unused side shelves and long shelf. Since we need a better coffee table than the one we’re using, we decided to knock together one from the failed closet attempt. I think the only parts I’m going to need is a saw (probably will by a handsaw since this isn’t really worth buying a jig for), and probably a four half inch square by 18 inch long blocks so that I have something to screw into. Maybe, I’ll need another two solid blocks that are 23 inches long for the back as well. Maybe even four more 23.5 inches long to run along the top too.

While I like the idea of building a table, this is going to look so horrible, it’s not even funny. Wood screws right through the sides, chipped melamine, and peeling edge tape. It’s going to pretty embarrassing. So why am I posting about this? I don’t know. I’m stupid I guess.

Well, maybe it won’t look that bad.

Sketch Up Model

Ukrainian Easter Eggs

Like many people, growing up, my family used to decorate Easter eggs, Only our eggs tended to be decorated like Ukrainian Easter eggs, or pysanky. My mom learned how to do this from a friend of hers, that truly an artist at it. Every year, we’d break out the beeswax candle, heat our styluses and attempt to draw deer or weave patterns, dots, or crosses on the eggs. Some years, we’d even bring out a hypodermic needle and a syringe and extract the yolks so we could keep the eggs for years.

I decided that I wanted to decorate eggs this year, but all we had was the crayon and dye that’s in a Paas kit, and the new dye containing cotton swabs. (Using the swabs are pretty fun.)

I pretty much resigned myself to not decorating eggs with candle wax for many many years, since I had no idea where to buy the stuff you need. Then for some unknown reason I checked out Make’s Top 10 Easter Themed Posts. In the list was a Ukrainian easter eggs. Following a couple of more links, I found out that that The Caning Shop in Berkeley sells everything. Hooray! Surprisingly, the book about how to make the designs my mom has had all my life is still in print.

imlibsetroot

Way back in 2004 when I was still using a multiheaded Linux box as my primary machine, I wrote a command line utility to change the background picture of my desktop. I gave it the catchy name imlibsetroot in the vein of other similar utilities, such as xsetroot and Esetroot. The main difference between my utility and these others was that mine allowed you to set different pictures on each monitor.

I posted it on my .edu account and must have made an announcement on Freshmeat, and figured no one else would ever use it. I mostly forgot about it. The program was pretty much complete, so it just sat there in “maintenance mode.” I used it regularly for a couple of years, added a single trivial enhancement/fix, and soon after that, I stopped using it when I switched to a mac.

I’ve thought about it from time to time. Mostly whenever I’m forced to deal with Apple’s horrible desktop background preference pane. Then today, while engaging in a vanity google, I found this.

Not only was there another user of imlibsetroot, but apparently he was a long time user, and fixed an actual bug, and then started hosting his fixed version himself.

Wow.

What else could I do? I downloaded his version, patched my version and then emailed him a new copy.

Just in case there’s someone else out there using it and will stumble across this, I’m posting it here, along with original imlibsetroot webpage, but with a link to the newest version.

Enjoy imlibsetroot 1.2!

I got off my ass and wrote a wrapper script for MacOSX. (I don’t think multihead is supported on MacOSX.) imlibsetroot rides again!

A Xinerama Aware Background Changer

imlibsetroot is pretty much Esetroot, but much more feature rich. This program was originally designed to set backgrounds on individual monitors in a multihead setup. Then composition was added so that it could be used with webcollage, but webcollage has its own program that does pretty much the same thing, so that was pretty much a waste of effort. Alas, I only checked how webcollage actually worked after composition was added.

Anyway, this is what I use to set my background in sawfish.

imlibsetroot requires Imlib2.

Enjoy!

Synthetic Plants

I’ve been thinking more about solar plants recently. I like how these projects combine both form and function. I’ve been thinking about what I’d like in one of these, and how one would be made. First, the power being collected by the solar cells needs to go somewhere. It could just feed back into the device, which is exactly what happens with plants, but part of me likes the idea of having the sculpture(?) have a practical use as well. If I want practicality, then USB ports for charging an iPod or a phone that I don’t have would be nice. At least one port, but four would be more than plenty. I’m leaning towards the solar cells charging some li-ion or nicad battery coupled with something like a Minty Boost.

The second feature I’ve been hammering the previous electronic plants I’ve looked at is the movement, specifically heliotropism (i.e. sun tracking). It’s an interesting feature, and it would increase the power to the photovoltaics. I don’t like the idea of the hearing servos move, so that means nitinol wires, which also have the quality of more closely resembling natural motion by simply expanding and contracting. The next question then becomes, what form would the motion would take?

If rigid photovoltaics are used, then panel could be mounted to a universal joint with the two outside corners independently controlled by nitinol. The other idea is to use flexible photovoltaics and hopefully no hinges and joints.

Another interesting idea is to think about deployable structures, which would seem to imply the use of flexible photovoltaics. It’s not exactly the heliotropism I was thinking of, but it would be cool if the “leaves” opened up in the day, tracked the light, and then closed at night.

Doing all of this nitinol might be kind of difficult. Heating nitinol causes it to contract in the 3 – 5 % range, doesn’t seem like much. This also means that for a deployable structure, it needs to collapse when the wires are extended,

Will I actually build this? Probably not, but it is something I’ve been thinking about. Perhaps it would give me an excuse to visit Noisebridge.
