Try to breath as the world desintegrates
Just like autumn leaves we're in for change
Holding tenderly to what remains
And all your memories are as precious as gold
And all the honey and the fire which you stole
Have you running through all your red cheek days
Shaking loose these songs from their sacred hiding space
Hold your heart courageously as we walk into this dark place
Stand, stare fast, erect and see that love is the province of the brave
Push under the ?(whizing lights) of buzzing stars
Let this burning brightly illumintate where we are
Build this hallow that lovers voices occupy
Let it follow
That we let it free, let it fly
Breaking open the walls of this cage
Intoxicated, oh so amazed
Much like falcons tumbling from our hearts that blaze
Oh come join, ?(arms engaged)
Hold these hearts courageously as we walk into this dark place
Stand, stare fast beside me and see that love is the province of the brave
"Province" by TV on the Radio

2007-01-23T11:20:47BDKR (mailto:bdkr@highsidecafe.com)GeneralIt's so so true. This is what I read over at Joels.
One of the unfortunate side effects is that your mind gets into a bad habit of overestimating how clearly it understands things. It always thinks it has The Big Picture even when it doesn’t.
This is a particularly dangerous trap when it comes to software development. You get some big picture idea in your head for what you want to do, and it all seems so crystal clear that it doesn’t even seem like you need to design anything. You can just dive in and start implementing your vision.
Now there is more you need to read before the above paragraphs to get a fuller understanding.
That stated, this kind of thing bit me in the arse this weekend. In the job I have now, I am learning a long list of new things (some of which are very easy) as I go. That long list includes Ruby, Ruby on Rails, Test Driven Development, and Agile development. It also means that some things that shouldn't take very long at all for programmers with lots of experience in a given environment are killin' me!
Friday when I left work with a Monday deadline for some new functionality I knew two things.
I figured out the cryptic interface for the module with no documentation.
The formatting of the generated information would be no big deal as it's using the same partial anyways right?
So confident was I that this stuff really wasn't a big deal, I didn't start Sunday morning like I had originally planned. Instead, I stayed Saturday night at a friends house after a show, had lunch, then didn't start working on it until 3 in the after noon. So sure was I that everything was under control, I even allowed time to chat with a particularly nice young lady sitting next to me with jet black hair and eyes like blue ice that bored right into you.
I'm drifting.....
Well, as I got down to business, the difficulties soon made themselves known and things became darker and darker. And what was the jist of the problems? Ultimately it's the fact that I'm still too new to Ruby to just be quick about it. A couple of things would've helped big time. As a matter of fact, my biggest gripe after this experience is with Pretty Print. Now I guess you can customize it's output, but I'm a noobler in Ruby so that's not going to happen while I'm under the gun!
The problem for someone that is accustomed to using PHP and it's various ways to dump raw data to the screen is that Pretty Print doesn't format the data in some nice way and it doesn't state if you are looking at a hash or an array. This alone caused me no end of heart ache. About 4 hours worth as a matter of fact. Once I figured out that the data set I was getting back was a hash as opposed to an array, a quick "to_a" sorted out all the drama and things started to look real sunny.
Now before you get started, I know what a hash is and how it's different then an array, but trust me when I say that the output from Pretty Print doesn't make that plain.
Anyway, the last two days of my life has been garbage! Tired as hell from 12+ hours of bumbling around in the dark writing code, the resulting lack of sleep, the 8 gallons of caffeine needed to stay awake through the day, my turbo car suffering a bearing failure, and my ex telling me that she might be pregnant. There's too much stuff going on and I've never been good at juggling.
And so far, I don't like Ruby!This is what I read over at Joels.

2007-01-15T14:53:46BDKR (mailto:bdkr@highsidecafe.com)Rants and RamblesAnd it's not the programming that's bad. It's the environment. Other coders and the tribal/religous side of it. My last job hunt and recent things I read over at Loud Thinking have really driven this home for me. For the sake of brevity, let's just talk about Loud Thinking.
Joel Spolsky recently posted a piece called "Language Wars" and really managed to step on some toes from those that drink the koolaid: the Ruby Devout. Of the things that he said, there are certainly a couple of points that I agree with in particular.
...it's known to be slow, so if you become The Next MySpace, you'll be buying 5 times as many boxes as the .NET guy down the hall.
I'm really not sure that you won't hit scaling problems, or problems interfacing with some old legacy thingamabob, or problems finding programmers who can understand the code, or whatnot. So while Ruby on Rails is the fun answer and yes I've heard of 37 Signals and they're making lovely Ruby on Rails apps, and making lots of money, but that's not a safe choice for at least another year or six.
...I'm sure you'll have a lot of fun, but for Serious Business Stuff you really must recognize that there just isn't a lot of experience in the world building big mission critical web systems in Ruby on Rails.
So while the above statements made the hordes unhappy and the pitchforks came out, there really is some truth in the things he had to say there. But instead of challenging him on those truths, they chose to call it FUD and be done with it. The really interesting thing is that he never said he didn't like the language. What he said amounts to "it's bleeding edge right now and it's prolly not to smart to use in in an enterprise setting", to which, I have to agree (but I also think it's cool if are choosing to be on the bleeding edge!).
Once again, there was no answer for this, but instead, "It's FUD and he's a jerk".
But the truth is that there are scaling issues to be sorted. And there are performance issues. On the topic of performance issues, it's not with Ruby itself in my opinion, as it's most likely "fast enough", but with Rails and it's use of ActiveRecord. ActiveRecord is an Object-Relational Mapper layer with the aim to abstract typical DB usage away as much as possible from the OO developer. Models obviously become very important keeping this in mind.
Anyway, all an object relational mapper is going to do is suffer the drawbacks of what OODBMS'ers call "an impedance mismatch". In other words, the overhead of developers trying to extend their object like hierchal view of data onto the database itself. In this case, retrieve the data then manipulate into something the developer wants to see. Now I wont argue the merits of wishing to view and deal with data in this manner, but the performance hit can't be overlooked.
That said, Rails has a big issue and it's very core: the performance of it's ORM.
The bigger problem for Ruby and all other languages with people developing Rails like frameworks with ORM's at their cores is actually bigger then the use of an ORM in the first place. It's the idea from zealous adherents that this is OK and that no real thought needs to be given to it. They've chosen to abstract the DB away so much behind various layers of OO fer-dizzle that most don't even know the term "impedance mismatch" or have never even heared of an OODBMS. So busy bowing before an alter and burning heretics, they seem incapable of realizing that using an OODBMS could solve the performance issues in one fell swoop.
But what do I know eh?

2007-01-11T08:54:44BDKR (mailto:bdkr@highsidecafe.com)Turbine DumpYeah, I've not been able to get anything related to Turbine Dump since I've taken this new job. I've got to get moved! I leave for work at 6AM and get home around 8PM. That's far too long of a day to expect to get anything of substance done away from work.
Man, I'm tired!
Man, I'm tired!]]>Which turbo to buy?
http://mgaps.highsidecafe.com/index.php?p=148&c=1
2007-01-07T16:48:50BDKR (mailto:bdkr@highsidecafe.com)VolvosAfter some discussion over at Turbobricks about options in turbochargers, it's about time to make a decision. Any more pondering will border on Barney'ism.
The objective of the car is simply to be a killer street car with a broad power band of useable power. Even as it it now, I've accomplished that objective. The car has mad grunt on the bottom end and absolutely steller roll on performance. The only downside is that I've not met my power goal which at first was 250hp, but has been moved to 300hp. 285 at the very least.
Anyway, with the turbo I have now (TD04H-15G), it's not likely I'll make that point with the next iteration of the engine. Well, it's possible but I doubt it will happen.
The next iteration includes a ported, polished, and grooved 530 head with a B cam. The B cam has a good deal more lift and moves the power spread a little further upwards in the rev range bu not too much that it will jepordize the our objective of streetability. Additionally, others have reached more then 300hp with that cam, though admittedly using larger turbos then I.
Now there is also a worst case scenario to the next iteration of the motor/turbo setup. As it is now, my car is smoking and I'm pretty positive that's from the turbo. However, there is an outside chance that it's actually the block and oil getting past the rings at idle. While I certainly hope that's not the case, it slows things down by at least a month. The good side of such an outcome is that it'll force me into a 90+ block, thereby removing any lingering reservations about the K block.
So back to the turbo stuff: The most likely choices, instead of those crazy expensive GT2871R's I was pondering before, are the Mitsu 18G-5H, Evo III Big 16g, or a T3/T4 with a .48 hotside and a 60-1 cold side. All of these turbos are very will priced and small enough on the hot side to make very little in the way of lag from my 2.3. The only drawback of the Mitus listed above is the need of a $40 dollar T3/DSM adapter. It's actually more of a risk in terms of the potential fitment issues caused. I guess that's the kind of thing we won't know for sure until we "go there".
There is of course one more option that also has had some discussion. That is using an 18g or 19t wheel in the 15g compressor housing. However, when you consider that I have to pay for the work AND the turbo CHRA still needs to be rebuilt, it may end up being more expensive then just buying a new turbo.
Anyway, all of these are very well priced options compared to the ball bearing GT family.

2006-12-22T14:56:17BDKR (mailto:bdkr@highsidecafe.com)VolvosWell, figuratively speaking at least. When I get back home tonight I will prolly go out for a spin even though I shouldn't.
The problem relates back to my hybrid 15g install. It's a 13c hotside/15g coldside. When putting it together I definitely noticed some in/out play at the back (exhaust) of the CHRA. As a result, it's letting oil past. While idling it will let lightly mist the area with blue smoke. That's not good! If I let shut the car off then restart it a couple of moments later, it will smoke fer shizzle and leave a thicker cloud behind.
So while it is fun, I really need to get it up in the air to deal with a host of things as well as change out the turbo. I really want a GT2871R or 3071RWG. Those are mad turbos and would go nicely with this motor. Especially the 2871 for low end and mid range responsiveness.
Oh well..... A guy can dream right?

2006-12-12T18:41:02BDKR (mailto:bdkr@highsidecafe.com)GeneralWell, it looks like I finally go back to work after looking for some time. I'll be employed with a company (start up) called Pay Per Post. It looks like it's going to be a blast. I'll actually be coding in Ruby and Ruby on Rails. I spent the weekend hackin' as a matter of fact. After going dark with a copy of "Ruby In A Nutshell", Google, and plenty of coffee, I hacked out a small command line app that stores phone numbers and emails for people.
Anyway, and for those that don't know, the language is a lot like Python. The differences?
* The interpreter doesn't squawk about indentation
* ABSOLUTELY EVERYTHING IS AN OBJECT
* Has some funky iteration stuff that is very concise and perl'esque as a result
* A lot of funky operators in the place of words. ('

I'm also not happy with what I had to jump through to generate a multi-dim hash. I may yet find a
better way to create dim hashes, but it certainly wasn't as easy as it was in PHP.

2005-01-19T14:30:54BDKR (mailto:bdkr@highsidecafe.com)GeneralJason posted a link to something on Google (dated today as a matter of fact) that should make bloggers all over Dodge happy. Basically it'a an attribute (rel="nofollow") that should be added to any hyperlinks generated by the comment (or whatever) functionality of ones blog software. It's obvious then that the Google Spider will not follow these links and any gain from the comment in the first place becomes nill.
Now this doesn't stop the comments from coming in. But once spammers realize there is no gain, they will most likely loose interest in placing the comment in the first place.
