An update Redux, Electric Boogaloo

Saturday, September 8th, 2007

Ok, neglected things here for a while….

Holidays photos are here. I had an awesome time on holiday, did a bunch of cool things, like sailing a catamaran, and scuba diving on the Great Barrier Reef. Damn, that was just too awesome. Also got to see a bit of what Australia is like, and has cemented in my mind, that I need to move over there (Melbourne specifically) to live.

Relatedly, everyone is leaving Chrischurch. Two of my friends are about to go to Auckland, one is  off to Melbourne herself on, um Monday, One has pretty much decided to shift to Wellington at the end of the year, another thinking about Dunedin, one is considering study in the US, my flatmates want to travel through Europe soon. ABANDON SHIP, LAST PERSON OUT PLEASE TURN OFF THE LIGHTS!

Just had a very stressful day, where things were very uncertain about my work situation, and it was looking like I was going to be unemployed just as I need to be saving money for the move to Oz.. but thankfully it looks like things have worked out perfectly, and I’ll be finishing up at my current place just as I’m looking to move. *whew*

Having hardware troubles with my PC. Very inconvenient timing. Decided that the motherboard is toast, which means a big upgrade in the pipeline as I can’t get a replacement part :( Not a welcome expense, but I’ll take the new machine over to Oz instead of building a new one over there. Swings and roundabouts I suppose.

Also the app I’ve built isn’t fast enough. I expect it will handle a large concurrent client load, but the individual request/response time is too long. Had a play with a profiling tool for the first time. Kind of cool. Decided that lookups/calls to EJBs, even “local” ones is really damn expensive and probably isn’t helping things. Hmm

On Lindon Puffin and Eric Raymond’s dating tips

Sunday, May 6th, 2007

On Friday, I cruised along to Al’s Bar (next the Pak n’ Save of all places) to see Lindon Puffin play a show for the release of his new (and very long awaited) CD, “Show Pony”. As always, Lindon was very entertaining, and was in fine form… the stories were very funny – I feel sorry for “Emily Archer” for whom he wrote clever little song about only meeting someone a couple of times and forming an obsession over it. Turns out a few people at the gig know Emily Archer.. and someone called her on his cell and was like “Yeah, Emily… yeah.. he totally did the song…. yeah….” (and then walked off outside). It’s a darn shame it’s not on the album. Was a little sad that he didn’t do more songs from “Stuff like that”, but the new material is very good, as were the cover songs he did, including unforgettable moments such as Snoop Dogg’s “Bitches ain’t shit” done on the Ukelele. He’s touring soon, so if you get a chance to see Lindon Play, do…

By some total random chance, I ended up going to the Christchurch Symphony on Saturday night.. one of Liz’s friends ended up with a spare ticket, and a few frantic last-minute txts, and a hurried jog to my car later, I was in the town hall listening to Grieg’s Piano Concerto, which was actually pretty enjoyable – the last time I’d sat down to listen to classical music was probably in my first year at university…

A google search for ‘geek dating’ turned up these three pages, which seems to offer some pretty sound advice, but the most disturbing thing, is that they appear to have been written by none other than Eric Raymond. Yes, this Eric Raymond:

Eric Raymond.. doing.. something

Of course, one cannot mention him without mentioning the excellent Everybody Loves Eric Raymond webcomic.

Oh, I solved my async JMS callback problem, using a fairly in-elegant hack, where I have a singleton object which maps the session bean instances to a reference ID, which I then pass in via the JMS message. It’s ugly, but it works :-/

JMS callbacks

Monday, April 30th, 2007

Apparently, Object properties of JMS Messages will only accept primitive object types (e.g. Integer, Boolean, String, etc), which is of limited use, as Message already provides putIntegerProperty() etc. I wanted to pass an object reference (to a Session Bean), so that I could (cleverly I thought) use it to invoke a callback, and thus be able to get results back from the Message Bean which was consuming the JMS Message.

Now that I think about it, such a thing would be completely useless across JVMs (or indeed across two entirely different systems, implementing JMS) which is why I suspect you can’t do it.

It would be nice if there was an easy way to do asynchronous calls in J2EE/JEE5 with a way of retrieving the results, without resorting to using your own threads or ThreadPool inside the container, which is apparently a big no-no. I’m gonna be thinking about this one for a while I expect…
