Square is often considered the go-to solution for mobile payment systems, but it has two shortcomings that could limit its uptake in Canada. Debit (via Interac) and Chip-and-PIN technologies are very popular here, and Square supports neither. As a result, there’s more of a competition opportunity here than there might be in the US.

Two competitors - Moneris and Chase - are big names in payment processing, and they are trying to get in on the mobile payments action in a big way. Intuit, a third competitor, is a very big name in accounting, and also wants a stake in the mobile payments arena.

If you’re considering getting a mobile payment device for your sales efforts, whether you run a street vendor booth or a full retail location, you should explore the pros and cons of each choice.

Lately I’ve been feeling a bit burnt out about technology and even the world in general. This summer has been a bit of a pounding in a few ways, at least if you follow the news. And I do follow the news - entirely too much. The world seems to be trending to a dark place.

Again.

But on the bright side, there’s one place that has always been dark and foreboding. No matter how bad the world gets, this one place can’t get any worse than it already is.

I speak, of course, of forgotten code. Not dead code, not mere legacy code, but rather, code that runs every day yet hasn’t been looked at by a developer in years. Often, the code was written in a hurry using the fastest time-to-implement solution available. Sometimes by a very inexperienced developer.

All of that means one thing: it could be vulnerable.

Changes are afoot: I’ve been given the opportunity to learn Ruby on Rails on a project at work. It’s been a while since I started a new language, and my last attempt at Python kind of fizzled, so I’m hoping that Ruby will be easier to pick up.

So Far, So Good

I’ve had some exposure to Ruby in the past, such as with Puppet modules and Capistrano deployments, but until now I haven’t really concentrated on understanding the language itself. Compared to PHP, it’s lean and clean. I’m definitely liking what I’m seeing.

Recently I had a side project that needed Next/Previous pagination buttons. Using Twig, a PHP-based template rendering engine I like, I was able to hack together a quick and dirty solution. Emphasis on the dirty - but, even dirty code can teach you something.

In this case, we're going to learn a few Twig tricks: advanced for loops, array merging, and custom macros.
