I’m frustrated right now. I’ve been looking for someone to write about a technology that tons of people have no doubt used and am coming up short. Really, this is my own fault, because I was hoping I’d find someone who wasn’t a white male to address the topic. There’s nothing wrong with a white male addressing the topic, but I’ve been recommending a lot of white males to write about technologies and I was hoping to put my money where my mouth is in terms of my hopes for the diversity of the field in which I work.

I checked a bunch of related repos on GitHub and found that the maintainers were white guys and the committers were white guys and the people filing issues were white guys. So I checked the Following lists of related Twitter accounts and found.. more white guys. The few women I found either didn’t blog or had Tumblrs full of inspirational quotes and cupcake photos and shit. (Which is fine. But not what I happened to be looking for an expert on.)

And so this is how I became frustrated, because I d

Cooperative Multitasking, Components, Nette & Flow

On GitHub I provide example or Cooperative Multitasking components on a single site served by Nette Framework. These components need to process several network requests to render themselves, which is normally slow.

This example takes advantage of yield operator (available since PHP 5.5) to switch between tasks, Flow as scheduler and Rect as parallel http client.

This post introduces the Flow framework and cooperative multitasking in general.
