I'm confused, didn't they open source it almost five years ago? http://developer.yahoo.com/blogs/ydn/posts/2007/07/yslow_rel... (though the license is now BSD.. but is this newer YSlow a different version that was not previously open source?)

(Update: Aha, there's a blog post at http://developer.yahoo.com/blogs/ydn/posts/2012/02/welcome-y... - it doesn't explain much to do with my question but it seems becoming BSD makes it more open source than under the Mozilla Public License? :-))

Oh no... They forgot to add .svn to the .gitignore A kitten has just died...

nice! I want more integration of this in everything.

That's the only name of internal yahoo projects i really like the Y at the start.

They append Y to anything. So there's usually names like YCoolThing. And you go about "why you are questioning CoolThing?!"

but YSlow is just perfect.

Im guessing it's both because of homophones in general and the fact that yslow is a deliberate play on this - "why is this page slow?"

Everybody says why-combinator, no? Certainly everyone I've ever heard, including interviewers, YC founders, pg...

It's read that way, but semantically, it refers to an actual thing in computer science, so it's not just a cute name.

wait you don't? As a non native english speaker I do parse it as "ypsilon combinator" but read it "why" anyway :)

If you're not aware why you're being downvoted - the URL of your submission goes there anyway, so you didn't need to post this. :)

Yeah, initially I had posted the link to the Yahoo Developer blog page announcing the same. But then I thought it would be apt to provide the link to the github repo itself , since the readers would feel more interested in the actual stuff !! So I added the link as a comment without realizing that the source link was updated too.

Maybe he edited the submission URL afterwards.
