Coming soon – My OO Cheatsheet

Yes, I finally got sick of developers not understanding that OO is an art of its own, and requires thought, training, and actually applying it to applications! Having done OOAD for the past 4 years, I think I can help jump-start your knowledge of some of the basics as well as the nuances of OO as I’ve seen it successfully applied. Actually, I really hope to give you a leg to stand on, as I hear so many OO discussions with viewpoints on one side or the other, with absolutely no basis for discussion (other than that’s what they think). I hope to shed some light on OO and ways to apply design principles that help cultivate a methodology that yields sleek performance and manageable and reusable code. And I think I can, given my experience…

I have the page on the site, but I won’t link to it until I clean up the current Q&A. It’s a little too late for proofing, even for me!

Amazon has waiting lines…

No, I’m not kidding you, I just finished up my holiday shopping for my out-of-town relatives, and as is normally the case, Amazon was my retailer of choice (for the most part). It makes wrapping and/or shipping those gifts OOT so much easier! But it looks like Amazon is having some load problems, as it kept misplacing my session, sending me to an error page that really didn’t make sense. I figure it’s their default error page, a bad one at that, but not all was lost as I was able to use the Back button and continue working. Eventually I was able to get thru by doing this about 10 times during the process, but it doesn’t bode well for normal consumers who won’t understand what the heck is going on….not that I’m worried about Amazon’s bottom line being affected by such a glitch….

BTW, I’m about to call Amazon and offer my services as Santa’s little helper, by helping wrap their outgoing orders. On average, they wanted to charge me about $4 per item to giftwrap it (everything was smaller than a breadbox)! Guess the only problem is I don’t live near one of their distribution centers to make it possible…but those workers must be paid well with that much coming in per item….even though the hours and workload pry suck. Wonder if they off-shore…

OO Cheatsheet is Up…

It’s started out somewhat sloppily. I started with the whole ‘returning null vs. returning an empty collection’ debate, and tried to explain why the answers were what they were, but it turns out to be a long-winded discussion, as there’s a lot of interpretation needed on the developer’s part. But I hope I at least helped reason towards a standard approach that has worked well for me personally.
