On the Proper Design of Exception Hierarchies
Nick Hodges
– Introduction Exceptions are all over the place in Delphi. Introduced way back in Delphi 1.0, they totally changed the way that folks looked at error handling. Previously, we’d do things like: ErrorCode := DoSomething; if ErrorCode > 0 then begin DoNormalStuff; end else begin ...

Flotsam and Jetsam #55
Nick Hodges
– Marco notes that Embarcadero has put out a press release announcing a 54% increase in revenue in 2011 over 2010. This is unequivocal, clear, unassailable good news. No amount of Chicken Little whining will take away from the fact that this is very, very good news. (It didn’t ...

An Interface Implementation Pattern for Consideration
Nick Hodges
– So I’ve been writing about Interfaces, and mostly talking about how you should use them. But as important as designing and using the interfaces themselves is how you implement those interfaces. I talked about the basics in the previous article, but there are some things that you can do ...

Okay, So When Should You Call Create?
Nick Hodges
– Okay, I want you all to notice that in my previous post about the use of Create, I was pretty careful not to say “Never call Create”. And near the start I said “For the most part”. So let’s be clear – just as I didn’t say “Never ever call FreeAndNil”, I’m not saying “Never call Create”. ...

Flotsam and Jetsam #54
Nick Hodges
– I like FireMonkey. Actually, I confess that I don’t know much at all about FireMonkey, but I like that it exists. I don’t use it, but I like that it is there, broadening the appeal of Delphi and generally advancing the cause of the tool we all love so well. So I was ...

Life is Too Short To Call Create
Nick Hodges
– Introduction Okay, so the whole FreeAndNil thing has been going on for a while. Some folks are understandably sick of it, but I’m not. I think it is an important discussion that actually reveals a much deeper issue – sort of like how a fight with your spouse over the toothpaste tube is ...

Why You Should Be Using Interfaces
Nick Hodges
– I’ve been railing on why you should be coding against interfaces, and a number of you have been asking me to write an article about it, so I did. It turned out to be pretty long, so rather than make it a blog post, I turned it into an article. Why You Should be Using Interfaces and not Direct ...

The Bookstore of the Future
Nick Hodges
– Bookstores are Cool I love bookstores. A lot of people love bookstores. I love hanging around in a bookstore and seeing what is new, what is popular, and what is available. I love seeing the cool games and other non-book stuff they have. I love how most bookstores now ...

More on FreeAndNil
Nick Hodges
– I love a good, testy comment section in a blog post. The discussion in the comment section of my FreeAndNil post has been interesting and lively. In addition, the thread in non-technical continues apace, with new threads springing up! Along the way, a couple of interesting ...

Produce More, Consume Less
Nick Hodges
– The world seems to be bent more and more on input. The internet company sells you almost exclusively on the download speed they provide, and couldn’t care less about the upload speed. Heck, we don’t care about upload speed much. We are migrating towards devices that don’t have ...

Flotsam and Jetsam #52
Nick Hodges
– Many of you have headed over to the Delphi UserVoice page and voted on your favorite new feature for Delphi and RAD Studio. (Feel free to go over and vote for this one or this one. ) I’m still an Admin there, and have been, well, doing a bit of administering. One thing I’ve been doing ...

Using FreeAndNil
Nick Hodges
– There has a large and ongoing thread in the Delphi Non-Technical newsgroup about the proper use of FreeAndNil. It’s been contentious and a tad touchy, too -- just as I like it. The discussion falls out into two schools of thought: Those that use FreeAndNil liberally ...

Flotsam and Jetsam #51
Nick Hodges
– If you missed CodeRage 6, or you didn’t get to every session that you wanted to see (hear?), it is now all online. That link also points to the latest offers and ways to find out more about XE2. I love XE2, and think it’s the best Delphi ever. And I say that not even ...

One Right Thing at a Time
Nick Hodges
– Wherein I discuss how to do things that you should be doing and how not to do things that you shouldn’t be doing…. Sometimes you tweet something and it makes sense to you, but then you realize that it also kind of begs for more discussion. For instance: “Things move so quickly that ...

Flotsam and Jetsam #50
Nick Hodges
– WooHoo! Made it to #50 of these Flotsam and Jetsam articles. I published the first one of these right after I left Embarcadero on July 20, 2010. That’s about once every ten days or so. Not bad. Seems like a long time ago in a galaxy far, far away when ...
