Hi John, it’s me: future you. You think you know everything about writing software, and you’ve been told this same thing by countless others. But take it from me: you know so little you don’t even know what you don’t know. You think you’re pretty clever. You always use a language’s cu...

As a teen and twenty-something programmer I often found myself tossing hundreds of lines of code at a problem. I see this pattern over and over again in the young programmers we hire at my day job. I've noticed that now that I'm in my mid thirties and have been programming for almost ...
is Mike Gunderloy's software development weblog, covering Ruby on Rails and whatever else I find interesting in the universe of software. I'm a full-time Rails developer and contributor, available for long- or short-term consulting, with solid experience in working as part of a distri...
Ian McFarland, Principal and VP of Technology for Pivotal Labs, reprises his popular RailsConf 2010 talk. Ian describes the technical and social aspects of how Pivotal practices agile software development.
I gave a talk the other day at the Flatiron School here in NY, and had a great follow-up discussion over email with one of the students, including a number of questions about Pivotal. She and I decided to open source the discussion so everyone could see one Pivot’s thoughts on the que...
Welcome to Michael Hartl's Home on the Web! You found your way here—you might as well stay a while. I wear several different hats, and if you poke around this site you'll get to know about a few of them. These days I mainly work as an educator and entrepreneur. I'm the author and pres...
Here we have a simple method for calculating Fibonacci numbers that we trigger five times, each in a separate thread and when the program has finished we print out the total time it took to run. When we run this under JRuby it takes under a second to complete, but if we switch Ruby ve...

Quer saber se este dia se aproxima? Observe o dinheiro. O dinheiro é o barômetro da virtude de uma sociedade. Quando há comércio não por consentimento, mas por compulsão – quando para produzir é necessário pedir permissão a homens que nada produzem – quando o dinheiro flui para aquele...
I recently ran into some code that forced me to integrate with a Java library. While using the library I found myself wanting to do a bit of interaction testing, which I've historically done with Mockito. As a result, I added the ability to do interaction based tests on mock Java obje...
A/B testing is probably not worth your time. When you start hooking metrics up to your product, the feedback is addictive. All of a sudden you’ve got lots of actionable data and you’re tacking validation goals onto feature stories. This is great, but I implore you to not take it too f...

The Boldest Keynote of SXSW 2013 Etymological buggery has brought me to define “religion” as one’s most personal and rigid relationship with the universe. But rigid doesn’t mean static, so there’s an art to attacking religious beliefs – one that Peter Thiel put to good use in his 2013...

Active Record scopes are an interesting thing to test. In projects I’ve worked on, I have seen many different patterns of testing, some much better than others. A little over two years ago I wrote the gem pg_search , which provides a sort of Domain-Specific Language (DSL) for creating...
I’ve been working with my client, Unpakt , for a while now. One of their core values is making people’s lives easier. They’re specifically focused on making it easy for people moving to a new home or office to find a mover, compare prices and book their move online. As a development t...
By default, if you simply run bundle install after running bundle package , Bundler will still connect to rubygems.org to check whether a platform-specific gem exists for any of the gems in vendor/cache . This behavior can be avoided by instead running bundle install --local . Note th...
Generating printable documents can be ridiculously hard, but it doesn't have to be. What we really need is not another special purpose application or kitchen-sink library, but a hackable platform instead. We are working hard on Prawn 1.0, which supports both high level APIs for the mo...
