Target is the object that the message is going to execute isn't it. For example, if it's self, that means that those parameters are for the timer object you just created. Please correct me if I'm wrong, I'm not trying to challenge your knowledge, just to learn as I go.
If you see my code before, I'm using NSDate for my timePicker. One favor, I'm not answering more quiz questions, I get your point.. I still need to learn more fundamentals.. I get it, just please contribute with the thread to find solutions or not.. (there are many Professional Forums).
If this were a "Professional Forum" I would just give you an answer. I want to know what you do and do not know, so I can help you learn it. So please don't take the questions as condescending, they will help us help you.
Think of objects as people, so to speak. Not only is the NSTimer an object, but so is your viewcontroller. So are the buttons. These objects know how to do things. These things they know how to do are methods. A message is an instruction for an object to do something.
cancelIt: is a method in your viewcontroller object, as are all the methods we have discussed. Then self would refer to the viewcontroller, not the timer. Self would refer to the timer if you had access to apples code that implemets the timer and you were modifiying that.
So a target is the object you are sending a message to. The message is the name of the method you want the object to execute.
[aTimer invalidate]; // tells the timer pointed to by aTimer to execute the invalidate method
When you press a button, a message is sent. The target and method are chosen when you make the connection in Interface Builder. In your case, the target is your viewcontroller, and the method is one of the start or cancel methods.
I asked the question becasue it is fundamental to what an NSTimer is/does.
An NSTimer sends a message to an object at regular intervals.
In your case, the NSTimer is telling your viewcontroller to execute the echoIt: every second. The important part is that your viewcontroller is an object, echoIt: is something your viewcontroller is doing (not the timer). You only have one viewcontroller, so anything it stores (for example seconds) will persit for any NSTimer you create.
Now look at the NSTimer documentation:

I'm sure that somewhere in their headquarters Apple keeps a build of OS X on AMD like they did with Intel. But Idon't think that anyone outside of Apple will see it at least for several years.
Would it even require a different build? After all, it's still x86 architecture no?

My understanding is that AT&T is pretty far along in its upgrade from HPSA (3G) network to HPSA+ (faster 3G). They're doing this to maximize their existing investment in their infrastructure, and they should be able to employ LTE a little faster than Verizon has been, since LTE is a more streamlined upgrade from HPSA+. They claim that this is best for customers long-term, because when LTE (4G) coverage gives out, users can fall back on widespread HPSA+ coverage with similar performance. Whereas with Verizon, when you move out of an area with 4G coverage, you notice a HUGE drop in speed going to their ancient EV-DO technology.

All anyone has to remember in a liberal vs conservative discussion is one simple fact: There has been no law ever initiated by conservatives to help working class citizens. All of these ideas- min wage, child labor laws, max hours per week, workplace safety, etc, all spring from liberal thinking, because liberals give a damn. Conservatives as a rule are too worried about who might take their hard earned money. You know the "sorry we just can't afford it" argument.
Minimum wages = unemployment, lower growth
child labor laws = limits free will and opportunities for youngsters
max hours per week = limits free will, opportunity for higher personal revenue
workplace safety = bureaucracy, red tape, lower growth
Don't be naive. The goals are the same, more wealth, health, prosperity, and safety for all. Conservatives simply disagree with your methods. They realize that a hand-out is NEVER the same as a hand-up, and that wealth earned is not generally earned at the expense of others, but rather to their benefit.
What if I said that liberals don't give a damn about working class citizens, and that only communists do for the same reasons you stated, just taken to the next level. Would that make sense? Sad. :rolleyes:
BTW, the anti-gay segment has no business being in this bill. All politicians should realize that individual bills should be able to stand on their own two feet instead of sneaking them by in such a disgustingly snake-in-the-grass fashion.

Transition.
The industry is undergoing a massive paradigm-shift, thanks to Apple.
I am not seeing a transition in the crucial paradigm. They're not slowing down on the desktop and notebook front. Sure, we might be moving towards a tablet computing form factor, but that already exists.

You'd expect Jobs would have some sympathy for the guy, what with his phreaking days before Apple.
ATM, Apple is making its money on the hardware device, so this really shouldn't hurt their profits too much, even if it does hurt the Store. Would it really be so bad if there were dozens of stores that sold content for (effectively) only the iPod? When Apple will freak out is when the Zune plays Fairplay content. With Microsoft flooding the market with billions of dollars of losses to kill its competition, don't expect this to take too long.
Apple is still committed to DRM. When they offer Apple Lossless files for download with CD-writing still enabled then I'll accept that Apple is DRM-ambivalent. Right now they aren't. And with $2 TV shows the bandwidth argument no longer holds water.

Some of AMDs embedded products would be very interesting if used on a small form factor i.e. tablet or PDA like device. Perhaps iTV uses AMD components???

With the supply problems they are having right now AMD is not the choice to supply MacBook components. Not when Intel have the capacty and a very strong lineup of products (Core 2 Duo is what they had in mind when Apple switched - Core Duo was just a stop-gap).

I'm not fond of Spanish Revival, but this is not the way of doing things...
For philosophical context, consider:
Apple does not have a "museum" of past products. Jobs considers any product which is no longer sold a failure (if it wasn't, they'd still be selling it) and not worthy of nostalgia.
If nobody is going to buy the Jackling House and live in it, then 'tis time to discard it and move on to something which someone will buy/build and live in.

The new educational pricing of the 23" makes it $899 now. That makes it much closer to the dell 24" price. Somewhere in the future (most likely far :p ) I want to buy a big display to go with my powerbook and use with my photography. I thought that display would be the 24" dell because the cinema was way more $$. However now, it's a much closer competition...

Most importantly, without thuggish unions, good teachers like my wife would make far more money than they do today, while the bad ones would make less or be fired.
So why is your wife part of the Union? Why doesn't she listen to your wise ideas and go make more money in a private school? If she's really a good teacher then she should be able to according to your logic.

Well, I've only gotten 8 songs from iTMS Norway, so far, and I doubt I'll get many more... I get all my music from the local library... :cool:
So, considering that I couldn't care less if iTMS was closed.
On the other hand, I could think of a number of things, that will affect my and most Norwegians far more than DRM'ed music, that the Consumer Council should be concern about before starting to poke into iTMS and MSN Music (or whatever that is called). Though I support their effort to prevent Apple (or any other) to change the terms after the sale is made, that Apple tries to reserve the right to do in the EULA. For that Apple might get a big fat slap...

Excellent! Although I think some are underestimating the utility of negative ratings in increasing the SNR of the forums. I can't tell you how many times I've read through a thread (especially a front page-based thread) with factual errors that no one catches for pages and while other folks speculate wildly based on that, and then others go into hysterics over the speculation and on and on... it gets ugly
A few points:
Does this use the vB reputation system? If so, I recommend the Public Display of Affection plugin if you're going to change things to show who up/downvoted. PDA was (last I checked) not explicitly compatible with 3.8.x, but I've got it running (see sig) on 3.8.1. (If you're not using the vB rep system, why not? You can hide the pips entirely, although my forum finds them useful, to judge the credibility of who's agreeing/disagreeing)
Seconding the comment about the style... the buttons just look... off somehow.
Definitely do NOT hide posts based on downvotes. It just doesn't work for forums. Comments, yes, forums, no. The number should just help speed up recognition of good and bad posts as such, not be a filter for them.
Not sure if I like the one-click interface. Using the regular vB rep controls requires 2 clicks (three, if you don't disable that damned JS alert) to give rep. It's a slightly greater commitment, which gives people a second to think before downvoting. On the other hand, it's one-click on reddit too, and I haven't up or downvoted every post and comment... it's a tossup.

MacBook Air: Though it's pretty, the lack of a 12" screen, the RIDICULOUS fixed battery, and the sloggy speed were real disappointments. I've my PowerBook for 4 years now, and it looks like I'm not going to replace it anytime soon. I've talked to more people who want just a small, cheap little notebook.
ITunes rentals is OK, I guess--they just need to beef up the offerings.
