A couple of clicks and I could be discussing Babylon 5 with people in…

The new .zip TLD is going to cause some problems
Many years ago, Google applied for the .zip Top Level Domain. ICANN, in its infinite wisdom, granted it. And now, I think, bad things are going to happen. You see computers try to be helpful. They see you wrote "visit example.com" and autolink the thing which looks like a domain name. That's handy - especially as most…

Investigating the impact of HTTP3 on network latency for search
Dropbox is well known for storing users’ files—but it’s equally important we can retrieve content quickly when our users need it most. For the Retrieval Experiences team, that means building a search experience that is as fast, simple, and powerful as possible. But when we conducted a research study in July 2022, one…
