I’m back

Thursday, June 10th, 2010

I made no announcement when I left, but I left on vacation on the 28th, and returned home last Sunday. Unfortunately, I fell sick two days before we left Maui. I’m just now getting over it. I also sunburned the top of my head the first time we went snorkeling, which is now peeling and looks like THE WORST DANDRUFF IN THE WORLD!

In any case, we had a fine time – two nights and a day on Oahu, staying in Waikiki, followed by the rest of the week on Maui at a resort a little north of Lahaina. Major activities were snorkeling, walking around, and taking driving tours to the summit of Haleakala and along the Road to Hana.

I acquired a new (to me) ukulele on Oahu – I had wanted to visit a ukulele factory while we were there, because I figured that more of them were likely to be on Oahu than Maui (most of Hawaii has a small town/rural feel – Honolulu is the largest city in the state). I knew that several of them gave tours, but we only had Saturday on Oahu, so I figured I’d be lucky to find any factory open on the weekend. The only two factory tours I found listed in the guide books were for the Kamaka and Koaloha factories. Kamaka only provided tours during the week, which was a pity, because I own more than one Kamaka ukulele, but Koaloha was listed as having tours at 10am and 1pm on Saturday. Since it was between our hotel and Pearl Harbor, we decided to stop on our way to see the Arizona Memorial.

It took us a little while to find; some of the street signs for the side streets weren’t too noticeable. When we got there, the large sign was out by the street, but it wasn’t obvious that you had to make your way to the back of a deep parking lot between other buildings to get to the Koaloha facility. We made it, though, and we could see two men working on ukes through the screens. The guide book was wrong, though – there were no Saturday tours, and these guys were just trying to catch up a bit on the weekend. Ah, well.

So, we went on to Pearl Harbor and spent a few hours at the Memorial. The main museum there was closed for renovations, but the movie and the static displays around the area were well worth seeing. When we left, we decided (spur of the moment) to take the Likelike Highway over to Kaneohe Bay and travel back along the coast. While there, we came across this driveway display, which I couldn’t ignore:

Fresh Ukulele

That’s Kimo Tulley. His older brother, Tangi (pronounced “Tung-ee”) made the ukuleles – Tangi Ukuleles was started by him and their father, Jim. I actually wasn’t planning on buying a uke; I’m working again, but I’m not earning what I was before I was laid off. I couldn’t pass up the chance to try playing a few of them, though. I wasn’t interested in a six- or eight-string uke – I’ve got a six-string Kamaka tenor uke already. I narrowed down to the two I thought sounded best, which were on the back table … the mango concert uke on the left, and the koa tenor in the middle.

Fresh Ukulele - back table

The concert had loud and clear sound, but I decided that I liked the sound of the tenor better; it was sweeter. Marion thought that the tenor sounded best, also. I still wasn’t going to buy, but at the prices he was asking ($160 for the concert, and $280 for the tenor – I was expecting at least two or three times that), Marion told me I’d regret it if I didn’t buy it.

So I did, although we had to go to an ATM first, because we didn’t have that much cash between us. I had brought my $20 pawn shop “beater” uke on the trip, but I hardly touched it after that – the Tangi tenor sounds so much better. It’s got some wear and dings, but nothing significant. I think it was built in 2005 … there’s a date branded in the wood inside, but the last digit is a little blurred.

I like having striker plates both above and below the strings; sometimes I strum pretty hard, and that has an effect on the instrument. Actually, if you look at Willie Nelson’s guitar, you can see that he’s worn through part of it after so many years.

Trigger

I think this is going to become my go-to ukulele. It looks and sounds beautiful, and it’s nice to have a good ukulele that has a good story associated with it.

How to deal with …

nostalgia for the Navy life.

A decision fraught with dangers

Wednesday, February 24th, 2010

The Department of Defence has decided to change policy in order to allow women to serve on submarine crews. Unless stopped by legislation, it goes into effect in 30 days.

This is not, to my mind, a good idea. I served on a missile sub back in the 1970s, and I doubt that too many things have changed all that much. Most commentary on the issue has dealt with the close quarters and lack of privacy. I agree with those concerns – as a junior officer, I shared a stateroom with two other JOs. Most of the crew had only a curtain on their bunk to provide privacy. Those aren’t the only concerns, though, and I’d like to address some others.

Let’s start with health issues. The big one is, of course, pregnancy. Pregnant women may not serve in shipboard billets; they have to be assigned to shore duty. This causes resentment in men, because they end up serving longer tours at sea because shore billets are filled with pregnant women. It causes problems on shore, because up to 34% of the billets are filled with pregnant women who are unable to handle necessary duties.

Ship movements can be affected – women who become pregnant prior to a deployment must be replaced, and submarines aren’t assigned superfluous crew who can take over as last-minute replacements. When I injured my knee while we were tied up to the tender prior to a patrol, I was told by the doctor that if I weren’t on a submarine crew, he’d have put me into the hospital. He didn’t, because there was nobody to take my place on the patrol. The latest information I was able to find showed that in 2005, 14% of all women in the Navy were single mothers, and almost two-thirds of the pregnancies were unplanned. It seems obvious that single mothers aren’t easy to assign to sea duty, and single women aren’t easy to keep on sea duty.

Operational security can also be affected. Particularly with missile subs, the idea is to head out alone and hide as much as possible. Missiles are less effective as a deterrent if the sub that carries them can be found and sunk before it can launch them. Normally, it takes a severe medical emergency to get someone medevac’d from a missile sub. Would a woman whose pregnancy was discovered during a deployment be eligible for a medical evacuation?

This brings up legal issues related to health. The atmosphere on a submarine does not match the normal atmosphere. Carbon dioxide has a significant effect on blood chemistry; when I was on the sub, the CO2 scrubbers couldn’t keep the CO2 level anywhere near as low as it is in the general atmosphere. The excess CO2 went into solution in the bloodstream and formed carbolic acid, dropping blood pH like a rock. The Navy was just starting investigations of long-term health effects when I was serving, and I don’t know what, if anything, has been determined about them. I would not take odds against someone bringing suit against the Navy and citing these issues if her child was born with problems. Or claiming that exposure to radiation was the problem – everyone on a nuclear submarine is considered a radiation worker.

Women on submarines is an issue that’s come up before – this comment on a Metafilter thread brings up several issues. There are others that come to mind – in the Naval Aviation community, it’s generally considered that you can’t make flag rank without having served in a command billet at sea. One of the original reasons for women being assigned to sea duty was the difficulty in advancement to high rank without having served at sea. I’m unaware of any similar requirement to serve on a submarine, though, unless it’s to command a submarine group, so that shouldn’t be an issue here.

Even without considering submarine duty, women in the Navy recognize that there are problems with women in the Navy. Not with all women, but there are both good and bad performers of both sexes, and the accommodations that are made for women provide opportunities that some women will take advantage of to the detriment of others.

I think allowing women to serve on submarines is a bad idea, for several reasons. But what do I know? I’m a guy who felt that it was a mistake to let women into the Naval Academy. Just because at that time women weren’t allowed on sea duty at all (except on hospital ships) was surely no reason to prevent them from taking one of the limited slots available, was it?

Is ‘oblivious’ on the checklist?

Facial hair, but not a full beard? Check.

Geeky personality? Check.

Hairy chest? Check.

Loves to read? Check.

Cries at soppy film endings? It’s my secret shame.

Gray hair? Check.

Glasses? For reading, anyway.

Passionate supporter of a sports team? Nope, that’s gotta be why I didn’t notice women throwing themselves at me when Marion and I were in England, nor do I see it now.

There’s an interesting post here about heisenbugs and compiler optimizers. I’ve found two compiler bugs in my time. One was related to the optimizer, although it wasn’t due to the compiler generating incorrect code. Well, not quite, anyway.

In one case, a commercial embedded cross-compiler, the optimized code the compiler was generating was logically correct code. The problem was that it was incorrect in context. I was accessing machine registers that had to be accessed with 16-bit operations – if you tried to access half of the register with a byte operation, the processor would overwrite the other half of the register with random data. Naturally, the compiler was optimizing 16-bit accesses that only dealt with one byte of the register to 8-bit operations, because that was the better thing to do when dealing with normal memory. The compiler could produce code for several related variants of the processor in question, and I’m not sure that the register restrictions in question applied to other processors at the time.

I reported what was happening to the vendor, and they changed it in the next release of the compiler, but I couldn’t wait for the fix, and had to use assembly language to produce my access routines.

The other instance involved an IDE that used GCC as a cross-compiler. Our code wasn’t working, and initial investigation showed results that made no sense – one passed parameter was getting the value meant for the other, and another was getting a garbage value. Closer examination of the generated code showed that the stack frame for the function call in question was being built incorrectly, which beggared belief. Why was it only happening on this one call, rather than on all of them? If it were a general bug, there would be virtually no programs would be compiled correctly – what was it about this one call? Further investigation showed that the vendor had grabbed a version of GCC that had been pulled from distribution after about a day because of a significant bug involving calling across languages – calling C routines from C worked, as did calling C++ routines from C++, but calling one from the other didn’t … the specific bug that we were seeing, although we didn’t realize that it was due to a cross-language call until we saw the release notes on the GNU website. We were lucky that the vendor provided the capability to tell the IDE how to access other tools, or we’d have been dead in the water on our project.

It’s not often that you run into compiler bugs, unless you’re the one maintaining the compiler (in which case you probably see them more often than you’d care to). Most times, the problem is in your code, not the compiler. However, you can’t rule it out, particularly if you’re doing things that stress the compiler’s capabilities, or use features that most people don’t require. Some people make a point of looking for compiler bugs, which is nice of them. It’s not what I’d care to do on a daily basis, although I have designed and written test code to verify that language features work as intended.

I think it’s great, but it’s not my style

I’ve known people who could and would, and I have no doubt that Cdr. Salamander is one, but Akbar Zeb is not a name I’d be comfortable using.

I just upgraded my cellphone. I’ve been using a Blackberry Pearl for a couple of years, and although it was nice enough, I was getting frustrated with it. I’ve now got a Motorola Droid, and I’m liking it a lot better. I’ve already decided that it’s got its own set of annoyances, but they’re different, and there are two things that the Droid does that I find to be much better for the way I do things.

First, you have to deliberately put the Blackberry Pearl into “ignore the buttons” mode; the Droid does that automatically and must be unlocked to operate. I can’t tell you how many times I’ve inadvertently dialed someone because my reading glasses or a pen pressed against the Blackberry keyboard.

Second, the Droid does GMail and the web so much better than the Blackberry Pearl that it’s an entirely different experience.

It’s also got a host of features that the Pearl doesn’t. Marion is quite taken by the map capabilities, especially the GPS information that enhances it. In any case, I’m having a grand old time learning what it can do.

that Abebooks keeps a list of weird books. Well, the UK site does, anyway. I actually own copies of this one (although mine isn’t signed) and this one, and I’ve seen a stack of this one in a discount bookstore and in a museum hosting a Franklin exhibit.

I think my daughter would want a copy of this one.

I own other strange books: among them, I have copies of Der Wizard in Ozzenland, a book on the black death to go with the torture book, a cookbook that contains a chapter on cannibalism, and an inscribed copy of The Mason Williams Reading Matter.

Just things to keep busy with on cold winter nights.

Update: And, speaking of weird books, and things with which to keep busy, here’s an article about a horror story you can buy.

I don’t like tequila anymore …

I’ve been seeing previews for Pirate Radio. I remember listening to pirate radio when I was a young boy in England. I was attending Eastcote Elementary, a school for American service dependents, and the school used chartered tour buses to get us to and from the school. The usual driver on my route, a slightly-built young man with an improbably deep voice, used to tune in one of the pirate radio stations (Radio Caroline, I presume, but I really don’t remember) because the BBC was, at the time, too staid to play rock and roll.

It was an exciting time in music, and much of my musical taste was set at the time.
