Redis is great for some things but is definitely not the right tool here. It's built mainly for serving up small chunks of info (or functionality) very quickly. And it kicks ass at that. This is a system that probably sees even more wri

Yup. It's a very interesting mix of using a subset of something very well known (MySQL) to get what you need done.

This was... lemme see. less /proc/cpuinfo Intel(R) Xeon(R) CPU X5570 @ 2.93GHz So it was a pretty high-end Nehalem proc already. And, yeah, we do have ECC RAM in the box, of course. Plus InnoDB does page-level checksumming to

As luck would have it, I'm an advisor for RethinkDB. They're doing great work, but also aren't quite ready for prime time either. I'm very optimistic for their technology in an OLTP system, but this is not like an OLTP system at all.

Yes and no. Fusion-io removes the io bottleneck but ALTER TABLE is still single threaded. So you're looking at a CPU bottleneck where only 1 core can be used. We just did a lot of ALTER TABLE work on one of our clusters WITH fusion-io dri

Do you really think that telling Craig is what gets someone blocked?

I'm not sure I'd characterize it as "guard that situation jealously." There's no jealousy involved.

I've actually built a feature that addresses one of the concerns in the linked article... now I just need to do the last 5% to ship it, I guess. No, I'm not kidding. But, yeah, we have a TODO list a mile long at craiglist. A lot of time go

Paul, this is pretty common legal language. I've seen a number of deals like this. As others have said, though, don't do it. You can probably come up with something much better.

That's probably best to get into after I'm not a Yahoo employee anymore, should I decide to get into it at all of course... :-)

Sorry it wasn't more insightful. Maybe after I've been there a few weeks I'll have more interesting things to say...

a few months ago twitter may have been interesting, mostly for the technical challenges. But now I'd rather hack on FriendFeed simply because it serves a supserset of the same purpose and is likely just as hard (in other ways) under the ho

Why should they? Respect for their potential users. Implying that I missed because of how I'd written my take on it seems a little odd. You do realize that I wrote it after the fact, right? Of course you do. But it's more fun to pretend

Uh, it's not a button, it's a link. Notice that it's pushed to the bottom and hardly given equal treatment as the actual button. If you've ever seen many eye tracking studies, you know that items in the location on the page aren't likely t
