The App Store
July 10, 2008

If you've been following along with the iPhone news, you may know that the App Store launched today.

First, I must say I was disappointed with the quality of the apps on the store, and even worse than the poor quality is that the developers of these apps are charging money for them. A lot of the apps that should have been free... or not allowed into the store due to extremely poor interface development... are $0.99 or more. I can only hope that these don't sell at all, and as a result are either made free or improved by the developers, or removed from the store.

That being said, for anyone who is wondering if I am working on an iPhone/iPod Touch app, the answer is yes. I have a couple more things I need to finish before I call it 1.0, but if all goes well it will be in the App Store sometime next week. However, unlike the Dashboard Widget, the app will not be free -- it will be $9.99. But I think it will be worth it, unlike some of the other apps in the store that cost money. And I'm pretty confident that, unless you like RPN, it blows away every other calculator currently available in the App Store.

Version 1.3 of the widget was put on semi-hold while I worked on the iPhone app, so I'm going to try to have it out sometime in late July or August. Sorry for the delay, but I think you'll understand when you see the iPhone app and how much potential there is with the device.

A breath of relief
May 16, 2008

Every now and then someone writes something on a website, and then Google indexes it, and then I encounter a problem and start going crazy trying to figure it out, and then I go to Google and search for something, and then I find that persons site and read it, and then my sanity is saved.

Today it was this site.

But seriously, that site was definitely was a huge help, thanks to the guy who wrote it.

April Fools! (sort of)
April 2, 2008

Ok, so I may have been a little vague yesterday. The irony, of course, is that I was telling the truth -- though I was only talking about changing the name PEMDAS, not stopping development on the calculator altogether.

You see, the problem with "PEMDAS", while a freaking awesome name, is that not everyone learned PEMDAS in school, especially in other countries (who knew?). Also, as time goes on, my focus will gradually shift to the Cocoa app, and I want the Cocoa app and Dashboard widget to share a similar name.

Although the current name of the Cocoa app, "Super PEMDAS", is probably one of the coolest names ever (especially with the icon), I don't think as many other engineers share my fondness for Mario. In my experience, it's hard enough to get engineers to even consider using a Mac, so getting them to use a program called Super PEMDAS is just one more hurdle to jump.

Finally, there is also a marketing aspect. Calling the app "Super PEMDAS" makes it sound like the Cocoa app is the Pro version of the widget, when really, I see the widget as an 'express' version of the app. It may not be obvious now, but I think as the Cocoa app gets better, you'll see what I mean.

But anyways, I'm still actively working on Version 1.3 of the Dashboard widget. I couldn't help myself, and rewrote most of the interface code, since that portion of code hasn't changed much in the past two years, and really needed an overhaul. Both the code and the interface look a lot cleaner now, and I'm shooting to have 1.3 ready in the next couple weeks.

'Til next time...

The End of PEMDAS
April 1, 2008

A little more than 2 years ago, I started work on a calculator, with the main goal that it would help me work faster and with less effort than everything else out there. Originally, it was actually called MikeCalc -- it wasn't even until June 8, 2006, a week before I made the calculator public, that it became known as PEMDAS.

I've been a little busy lately, as you may have noticed with the lack of updates, so sorry for not announcing this sooner. But I've been thinking about it for the past couple months, and I've finally come to a decision -- that after 8 public releases, I've decided version 1.2 will be the last release of PEMDAS.

At some point, I'll try to post a follow-up with a bit more explanation. To the fans of PEMDAS, I apologize. But I think it's for the better.

Thanks for understanding,
Mike
