+1 For Brother laser printers. I've had mine for a few years now, and only gone through 1 cartridge of toner. It works with my Linux setup too.

I just checked a few newsletter emails in my inbox, and they all offer List-Unsubscribe: mailto: based unsubscription. From what I see, it is quite universal and more common than link-based unsubscription. Newsletter providers prefer not

How does this work from a technical perspective? If I forward mail to this service instead of clicking the 'unsubscribe' link, then how do they 'unsubscribe' me on my behalf? In order to complete the unsubscription pro

hah, because you care so much, I'll go ahead and make that change. It's probably better for SEO anyway. I made the change on my local copy. It will get pushed next time I re-build the site.

As the author of this blog post, I find this statement interesting. Can you expand upon the sentiments expressed in your statement? Also, by 'read this', do you mean just the blog post, or contents of the works by Jim Roskind?

Agreed on the point that there are better mental models out there. The difficulty is to make content that is simultaneously correct, but also not over-complicated. I finished off the post with a reference to Russ Cox's work so any su

You found a bug. The bug was: When I was computing the animation frames for the visual, after a backtracking event, I forgot to restore the 'progress' values for the PROGRESS nodes to what they were before the stack push took pl

The goal with this article was never to show the best or most efficient way to match regular expressions, but rather to convey the correct interpretation of what a given regular expression will do when you try to use it. Even discussions o

The (?:stuff) part is for a non-capturing group which I didn't add support for. Maybe in the near future. That would be one of the easiest features to add since the tool also doesn't support backreferences yet. Edit: Actually,

I'll provide another voice to support the idea that d3 is a really great library. For anyone who has tried to learn it in the past and found it a bit too complicated, I'd suggest you approach it with the following perspective: L
