A couple of geeky items

1. I’ve been playing around with SQLite on my linode. The database generation script runs twice as fast as when I use MySQL. But I’m having one major problem with the update script – it’s probably due to the Perl DBD::SQLite, rather than SQLite itself, but if I insert into a VARCHAR column using


my $wptInsertStmt = $conn->prepare(qq{
INSERT INTO wp_test
(id, datasource_key, tpa)
VALUES (?, ?, ?)});

$wptInsertStmt->execute('abc', '111', 555);
$wptInsertStmt->execute('1E2', '222', 123);

the ids that look like numbers get interpreted as numbers, so that ‘1E2’ gets inserted as ‘100’. Both MySQL and PostgreSQL versions of this code get it right. I suspect I’m going to have to convert the code to use bind_params, which will bloat the code and lead to problems if I get it wrong. It also appears I have to close all my prepared statements.

2. I hereby officially declare THE DEATH OF THE FLOPPY. I was using a floppy to transfer files between my development machine and my test machine. But the shutter on the floppy I was using suddenly stopped working. So I got another floppy, and after a transfer or two, I started getting I/O errors on the new floppy. So I grabbed another, and the same thing happened. That’s when I realized that when the spring sprung, it probably fell off inside one of my floppy drives and is still wreaking havoc on every floppy I used since. Unfortunately I couldn’t find my USB drive, so I had to beg one from a cow orker. Even if it is at home, I’m thinking of buying one or more new ones. They’re certainly cheap enough.

3. The LUGOR mailing list today is full of the plaintive crys for help from a guy who seems to be doing web design for a guy who doesn’t seem to have gotten the idea that a corporate web site should be about content, not craptactular toys. The first request was for information on how to put an animated train running around the borders of the web page. Evidently the boss is a dentist who has toy trains running around the office, and he thinks this would transfer well to his web site. The other, equally brain dead request was for putting automatically translated versions (ie Systrans or Babelfish, not human translated) of all of his web site up and automatically directing people from those countries to the “translated’ version. Can you imagine what a great image you’d give to people in non-English speaking countries subjecting them to Babelfish versions? Especially since you’d be automatically redirecting them there, even if they spoke English. I told him to look at Engrish.com and imagine people all over the world submitting his site to the local equivalent of that site.

I suppose it was too much to hope for.

The other day they “upgraded” our Lotus Notes to a “6.0 style”. Evidently I had been using a “4.x style” without upgrading it. Ok the new view looks more modern, but it’s slow. Even by Bloated Stoats standards it’s slow. About the only thing I like about it is that when you delete something, it actually goes away off the list instead of still being there but with an “X” beside it until you hit F9. The user interface still sucks like a really sucky thing.

One of the things I really hate about Lotus Notes is that it doesn’t just encourage “TOFU” (Top post Over, Full text Under), it makes it hard to NOT do it that way. I noticed an option on the “reply” button that says “Reply with Internet-Style History”. Dare I hope? Would this be a way to do trimmed quoted text with the reply text interspersed? Breathless with anticipation, I clicked it. And disappointedly, I exhaled. I ended up with the cursor at the top, followed by the reply to the reply to the reply, then the reply to the reply, then the reply, then the original text. And it was quoted with a single line of “>” quote marks, not multiple quote marks for the multiply replied to text.

Oh well. I still continue to expect miracles, I guess.

Nice flight

It was a surprisingly nice day. Actually, I hadn’t noticed it was going to be a nice day until I was reading Information Echo, where he was opining how he was going to miss the flying day due to family commitments. I quickly hit F12 to bring up the Dashboard, where the Aviation Weather widget showed me that the only clouds forecast were high cirrus. Ok, not exactly sunny, but extremely good VFR throughout the region.

Today’s interesting discovery

I’ve just discovered  lighttpd, a small memory footprint web server that supports all the stuff I currently use on my Linode – it’s got server side includes, fast cgi, simple virtual hosting, and mod_rewrite type redirection.  And Ruby on Rails supports it.  Ruby on Rails also supports SQLite, a small memory footprint SQL RDBMS.

Considering the small memory on my linode, I’m thinking that a transition from Apache and MySQL to lighttpd and SQLite might be just the ticket to improve the performance.  Which will be important if I start playing around with Ruby on Rails, because these “do everything including the kitchen sink” things tend to be memory and CPU hogs.

Now I’m trying to figure out how to test a transition.  I could install both of them on my home server and run it on another port.  I could install both of them on my linode and run it on another port.  Both of those options have the problem that it’s not a 100% accurate test, because I’d have to change the code to support a different port, and then change it back if/when I make it the true thing.  Another possibility is to buy another Linode for a few months and try it out there.
