Introduction Big O is all about saving time and saving space, two resources that computer algorithms consume to do repetitive jobs (like sorting strings, calculating sums, or finding primes in haystacks). Big O analysis is required when data points grow very numerous. If you need to sort thousands, millions, billions, or trillions of data points […]
Hey! Who remembers that comic book manger app I was writing a few months ago? Not me! Actually I didn’t forget about Book Binder–I just smacked into my own limitations. I had to take a break and do a bunch of reading, learning, and experimenting. And now I’m back. Look at a what I did… […]
A robot that a human wrote, wrote this post!
I hear that many of the applicants we interview still have a hard time with FizzBuzz and other simple examples of looping, testing, and printing integers. This was true in 2007 when Coding Horror wrote this a famous blog post on Fizz Buzz, true in 2010 when DanSignerman famously asked StackOverflow about it, and true […]
A couple decades ago the costs of putting up a website seemed really reasonable–especially as compared to pre-Internet media like books, newspapers, and encyclopedias. A lone webmaster toiling away in the wee hours of the night could get a site up and running with HTML and CGI by the break of dawn. Pages were static, […]
I wrote a tutorial that demos how to use a couple of UITableViewControllers, a segue, the Storyboard, a simple model, and as little code as possible to create an iOS app. https://github.com/jpavley/Smith You’ll find the code and a very detailed README on Github. It’s open source and I hope you find it useful.
My comic book collection iOS app continues to evolve. I continue to strip out features and focus on the core mission: Buy a comic, snap a photo, add it to your collection. With that in mind the UX now looks a lot like a photo app that has been preconfigured for storing comic book metadata. […]
I’m still working on that comic book collecting app! It’s starting to look and feel like a real app but still has a long journey of test driven development ahead of it! Here’s what it looks like so far… On the left is the Summary View and on the right is the Detail View. The […]
I’m working on a hobby project iOS app that lets me track my comic book collection. I’m interested in comic books because all these super heroes from my misspent youth rule the world of popular culture. While the cool kids were playing sports and going to parties I stayed at home reading comic books. In […]
I’m on that Apple program that where you pay for an iPhone over time and you get the opportunity to update immediately when a new model comes along, as it does every year. While this is a very good deal for Apple, almost like a subscription service, it’s a good deal for me too. I […]
