Some notes: This has got to me the most inefficient way of doing it. I’m sure I’m using a shit ton of memory for no goddamn reason. I did it that way because I wanted to use some fancy Matlab function and so it doesn’t look like every other version in every other language.

I’ll have to catch up tomorrow and use a language whose file extension isn’t “.m”.

#import <Foundation/Foundation.h>

#import "Person.h"

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    Person *eric = [[Person alloc] initWithName:@"Eric"];
    Person *world = [[Person alloc] init];

    [eric printHello];
    [world printHello];

    [pool drain];
    return 0;
}

Person.h:

#import <Cocoa/Cocoa.h>

@interface Person : NSObject {
    NSString *myName;
}

- (id)initWithName: (NSString *)name;
- (void)printHello;

@end

Person.m:

#import "Person.h"

@implementation Person

- (id)init {
    return [self initWithName:@"World"];
}

- (id)initWithName:(NSString *) name {
    [super init];
    myName = [[NSString alloc] initWithString:name];
    [myName retain];

    return self;
}

- (void)dealloc {
    [myName dealloc];
    [super dealloc];
}

- (void)printHello {
    NSLog(@"Hello, %@!", myName);
}

@end

It’s pretty simple first program (mainly because I decided to do this at the last hour). It probably leaks memory all over the place because I don’t remember how the hell to do memory management in Objective C (all the autorelease pool stuff is default Xcode template).

Let’s see if I can keep this up.

Hopefully I’ll come out with something with more content than this (after a couple good posts and a long hiatus it seems). I know, it gets tiring.

I had a longer post, but I don’t think anyone wants to hear it.

I must say, the EA support pages are pretty horrible. It’s difficult to find support articles (worth anything) or to get patches.

I’d really appreciate it if someone could help me. I run the game on the top 24-inch iMac that just got released (Stock, except for a bluetooth mouse. Stats are in the Systems page). Here is the messages I get on the “Game crash” screen:

: < << DID YOU REMEMBER TO BUILD DATA??? >>>

Because of the severity of this error the game will now exit.


Looking at the images above, you can see Apple decided to be cool and continue the aluminum body all the way to the end of sleeve.  Most people seem to just toss the cables is frustration, but with a trip to the local store, you can get RCA adapters and use a short set of RCA cables (that you probably have laying around) to go in between.

This seems pretty simple solution, but I haven’t heard of anyone actually doing it.  With the adapters, you can put use a little bit of force to get the on the cable and just leave them on after you are done.  I’m pretty sure there is some loss in the adapters, but it’s better than nothing.

The tour check in was a bit rocky, but eventually turned out to be one of the better tours I’ve been on.  It started off with a discussion about sustainability, and how the Yard is the newest facility and how they took the opportunity to reduce energy use and reduce other wastes.

Once we made it down to the shop floor, we walked along the tracks with some explanation about various things we saw on the way.  Next up, we went into a R62A and were able to look around (including the cabs) and ask questions.  There they gave us a demo about the door systems and it’s safety features.  The three little kids on the tour were able to play around with the PA and make announcements.

After the demo, we continued along and was show the various part underneath the car and was show the machine that rounds the wheels (while they are still on the car).

Another demo was given about how they give the cars “third rail” power with the overhead power connectors (I think they were called bugs (or was that only for auxiliary power)) so they can move the cars into and out of the shop.

At the end of the tour, they handed out little plastic baggies with the wheel shavings, “7″ stickers, and a pamphlet.

It didn’t go quite as smooth as the previous upgrade, so please tell me if anything seems broken.

Posted the pictures I took on the “Nostalgia Train” excursion to Far Rockaway.  Just a photo dump, no editing except for size.

The trip started from 57 St/7 Av on a set of R1/9 cars.  We then proceeded to Queens Plaza to get on the E line so we could go down Eighth Av into Brooklyn.  There was a brief stop at Court Street (the NYCT museum; yes we rode right into the museum), then headed to Rockaway Park.  If you stayed on the train, you would have gone to Far Rockaway and back across the bay before going back to Rockaway Park.
