What's it all about, Alfie?

This morning we realized that some of the fundamental data we are using in the Greek Engine is not fixed for each security, but in fact, is dependent on the prime broker for that trade. This means that we needed to take that piece of data out of the security definitions table, and make it a separate data table, with set names, and all that noise, so that we could define the right rate in the profiles.

It's a complicated way of saying we took what we believed to be a dependent variable in the Greek Engine and made it independent. The upshot of that is that we needed to be able to handle data source updates as well, and that means threading this new independent variable's updating scheme through out the code. Not horrible, but it takes time to do it right and update all the classes where the control logic needs to flow.

In the end, I wanted to get this done before lunch, and I just made it. Nicely done, as the last time I did this it took me all day.

Today my co-worker and I finally figured out the last, nasty bug in the Greek Engine that I've been working on for quite a while, and it's brought to a close a stage in my life that brings with it a lot more questions than answers. I've been working on this project for about six months, and while that's not very long for a project of this type, it's a long time to be getting a lot of grief from upper management about the time this project is taking, and the fact that it's not already in production.

I'm no idiot, I know that the finance industry is focused on What have you done for me today?, but when I'm asked to build something like this Greek Engine, and it's clear that it's not a four week project, then it's tough to sit here and take the accusations of incompetence and neglect when what I'm building is for the benefit of the name callers. I'm thrown back to the Little Red Hen: Who will help me back the bread?

In the end, it doesn't really matter because I did this for me, and not for them. I choose to not deliver crap, and they are the hapless beneficiaries of my morality. It's not something I'm necessarily proud of, but it's what I've come to see as the way things often are. I make a choice, and for the most part, there are detractors, and many of those detractors are in fact beneficiaries of my work. I do the work under their critical and harassing eye, word, and act, and in the end, they are the ultimate winners in this game.

Which, of course, isn't true at all, is it? They don't really win, because they don't have the ability to do what I've done, and they probably don't even have the ability to maintain the work I've started. But they benefit because they get to use the software I've written, and as long as I'm willing to allow them to play their sad, little role, they believe themselves to be my master.

But they aren't.

And it's not even close.

But today I've finished the last major problem on this project. It's now going to be a bunch of little features that are pretty easy to put in the code. Nothing major, and there's no real performance issues to deal with. It's pretty much done. I can sit back and look at the work I've done and smile. It's amazing work, really. I never thought it'd come together in six months, but it has. That's an impressive delivery schedule in my book.

And that's the only one that matters.

This morning I saw that Google Chrome dev 16.0.912.4 was out, and includes the new V8 engine 3.6.6.5 as well as quite a few nice Mac improvements including OpenGL. It's getting faster on the redraw, that's for sure, so I'm happy about that. Keep them coming, guys!

This morning I saw that Google Chrome dev 16.0.904.0 was out, and there were not a boatload of happy folks about it. Seems there's a recurring theme of not working with twitter.com, and there's a good number of folks that are plenty miffed about it. They changed quite a few things, and it riled the masses. So it goes, hopefully, they'll have it figured out soon.

OK, so I ran into what I thought was a bug in a user-defined PostgreSQL function regarding the holiday date for today. It's a Bank Holiday, but it's not a Market Holiday. I was able to prove this and fix it (temporarily) by changing the status of today's date:

  UPDATE calendar
  SET bank_holiday=TRUE
  WHERE calendar_date='2011-10-10';

and then the function I was counting on for telling me if today is a holiday started working.

So I knew the problem. But how to fix it? Well… it wasn't clear from the psql command-line how to do just that. I did a lot of googling to try and find out how to list functions, create functions, etc., and in the end, as luck would have it, PostgreSQL itself had the answer: \ef get_market_hours_for_date

The format is 'e' for edit, and 'f' for function, and then the name. If you just have the '\e', then it pops out into your EDITOR of choice for the last SQL command that was executed. If you give it the 'f' and a name, it'll pop you into your EDITOR and then let you edit the function.

Very nice!

These are the kinds of tools I'd expect from a commercial vendor, but I suppose, this is also what I'd want if I were working on PostgreSQL databases all day. I'm just really surprised and happy that these developers are thinking along the same lines. It's a great feeling to use such a fantastic database for my work - Mac and linux. It's nice to see the progress in time as well. It's really coming along.

This morning, as I was getting ready, I realized that I was really worrying far too much about what was happening at work. In a technology all-hands meeting yesterday, the CTO presented the status and plans for a bunch of projects that are happening in the group. In fact, I think he hit on everyone that's more than a couple of days long - it was pretty exhaustive. So when I heard there that several projects didn't include the work I was doing - even though I was told my work was critical to these efforts, I got upset. Really upset.

If I'm working 13 hour days for this project, and it's not critical, what am I killing myself for? What's the rush? Why work so hard? No, I was told that this work I was doing was fundamentally important to the effort, and what's why I've been working this way. In short, I've been a Good Team Player - internalizing the external needs of the Team even though they are painful for me.

But in the show this morning I realized that there's no reason for any of this worry and concern. I'm giving it everything I can, and if it's not enough, then they need to replace me. If they think I'm doing a decent job, then I think things are just fine. After all, this is the place where it's expected that everyone be extraordinary (got this in my last review).

So I realized in the shower that there's no reason to get upset. I've been angry at management for quite a while, and in the end, the fact that they haven't fired me, or moved me onto a different project, means that they must think I'm "meeting expectations", and by their own definition, delivering extraordinary results.

I know they don't think this, but I'm tired that once again it seems that I've forgotten the most important lesson of working in a group - do your best, and if that's not good enough, then it's time to move on.

I'm ready to make them make that call.

Just got a tweet that BBEdit 10.1 was out with a few interesting new features. There are several that sound interesting, and they're doing a bang-up job of getting the word out on twitter and YouTube about the speed of the search and replace, and the new features. It's just that I'm not doing a ton of Mac work right now, and so I haven't had a lot of time to mess with these features, but I'll get to it. Just a matter of time.

I'm still waiting to see them put in the vanishing Lion scrollbars, as that would be fantastic in my opinion. One of the singularly nicest additions in Lion are the vanishing scroll bars. They allow you to tell what you need to know, when you need to know it - but get out of your way when you don't. Very slick.

So it's downloaded and running - just need a little time to play with it.

They're at it again… Google Chrome dev 16.0.899.0 has been released and looks to have several nice improvements - including updating the V8 javascript engine to 3.6.4.1. It's nice to see that it's as responsive as recent builds, for there were a few in there that had issues, shall we say. Good to see progress.

This is another of those really neat web-based tools for documenting your code: websequencediagrams.com. What a cool tool! This guy allows you to type in your transition diagram and then it'll render it for you in many different styles - including a very nice looking hand-drawn style. This is perfect for those times you need to whip up a simple sequence diagram and don't feel like all the mess and fuss of something like Visio.

Take a look. Pretty sweet.

I saw on the ZeroMQ mailing list this morning a slick little web site, asciiflow.com, that allows you to easily draw ASCII flowcharts and then grab them for text documents. It's nothing that you can't do with vi or any other editor, and it's not as nice as Visio, or something like that, but it's nice for those times that you need an ASCII-art representation due to the document requirements you have.

It's interesting. Worth remembering.
