Part 17: Just Another Way to Spell “Callback” This continues the introduction started here. You can find an index to the entire series here.

Today I made my blog my main website, since the old one was getting kind of crufty. I moved the stuff I wanted to keep into WordPress, including my collection of links to programmer’s editors. The old /blog URLs will continue to work.

Part 16: Twisted Daemonologie This continues the introduction started here. You can find an index to the entire series here.

This works alright for development, but it’s hardly a way to [...]
Part 15: Tested Poetry This continues the introduction started here. You can find an index to the entire series here.

And you may be wondering how you can test asynchronous code using [...]
Part 14: When a Deferred Isn’t This continues the introduction started here. You can find an index to the entire series here. Introduction In this part we’re going to learn another aspect of the Deferred class. To motivate the discussion, we’ll add one more server to our stable of poetry-related services.

Introduction Recall poetry client 5.1 from Part 10.The client used a Deferred to manage a callback chain that included a call to a poetry transformation engine. In client 5.1, the engine was [...]
Part 12: A Poetry Transformation Server This continues the introduction started here. You can find an index to the entire series here. One More Server Alright, we’ve written one Twisted server so let’s write another, and then we’ll get back to learning some more about Deferreds. In Parts 9 and 10 we introduced the idea [...]
Part 11: Your Poetry is Served This continues the introduction started here. You can find an index to the entire series here. A Twisted Poetry Server Now that we’ve learned so much about writing clients with Twisted, let’s turn around and re-implement our poetry server with Twisted too. And thanks to the generality of Twisted’s [...]
Part 10: Poetry Transformed This continues the introduction started here. You can find an index to the entire series here. Client 5.0 Now we’re going to add some transformation logic to our poetry client, along the lines suggested in Part 9. But first, I have a shameful and humbling confession to make: I don’t know [...]
