I'm in training for two days this week (which is annoying, to an extent, because I have 2 days of work that needs done this week, and only one day in which to do it before going on vacation, which means I'm likely going to need to work on Friday, not that this has anything to do with anything). The training is focused on applying "Lean" principles ( Read more... )

I've been hearing all sorts of stuff about Haskell lately. It's a programming language that has all of my favorite features: it's a functional language, it uses pattern matching on function definitions, and it's got a very sparse, simple, syntax ( Read more... )

I've discussed Idea Mining before: every idea that pops into your head, jot it down. When you're looking for inspiration, or have some time to develop some idea, poke around in your mine and see what grabs you.

I started using Evernote, which had the advantage of syncing, but recently switched to Notational Velocity. It lacks syncing, but is much ( Read more... )

Words like "breathtaking", "stunning", "astounding", "amazing", and "incredible" are not positive words. Oh, they're often used in a positive context, but in reality, they only convey a sense of wonder and disbelief. They can be applied to something horrifying just as easily as something delightful ( Read more... )

Programmers, when they're really concerned with being efficient, will often start talking about "Big O" or "Order". There's a lot of interesting math behind this, but what it boils down to is a very simple concept- how many operations does it take to solve a certain problem, using a certain algorithm? I'm going to simplify things here, ignore the ( Read more... )

I love functional programming. I'm going to present on doing FP in VB.Net in August- this is a feature new to .NET 3.5. I was very excited about the ability to do functional programming in VB.Net. And some of the key features I really wanted, currying and closures, are there ( Read more... )

Here's a demo of my current project- an iPhone app called "Gravitone".

Not content to have exceeded the assignment's requirements by adding a graphical layer, I went a few steps farther: I added support for animation and multitouch gestures. The latest version of the source lives here, and it's chock full of comments this time.

Once again, it's under a Share-Alike-CC-license. Don't hand it in as your homework.

Stanford University is publishing video and assignments for their iPhone programming course online. I've been following it and doing the assignments, and man... I miss compsci classes. I've been having so much fun doing this. For those that recall me in college, I was a lazy underachiever in most of my classes- but not the programming ones. In ( Read more... )

The puzzle I posted about yesterday is fixed ( Read more... )
