Will do. Talking to some people here, they think your DSSIM tool [1] isn't what I should use. Specifically, they said it runs blur and downscale steps aren't part of the SSIM metric. They suggested using Mehdi's C++ impleme

It looks to me like they're trying to use not being in AMO as leverage to get Mozilla to implement additional security features. If they said "we'd like these features, but we're ok being in AMO in the mean time" M

I'm surprised bicycles don't try v-belts. With a standard frame the chain goes through the rear triangle. To install and replace the chain you need to be able to open it at a master link to get it around that piece of t

We set default quality parameters for PageSpeed with the goal of producing equal quality images between WebP and JPEG, on average (quality 80 for WebP, 85 for JPEG), but you're right that in this case the WebP image is more distorted a

And I guess if Safari had supported WebP back when Chrome and Safari were on the same codebase you would haven't counted them as separate browsers either?

In practice webp isn't usually spoofed, and when it is it's by people who've thought through the consequences and are in a position to deal with potential breakages. Client side feature detection can also be spoofed, but in p

The problem with solving this in content negotiation is that breaks proxy caches. If you serve uncachable html that references either jpg or webp then you can serve those resources as "Cache-Control: public", and if you include a

Isn't the problem more that the browser can't be given multiple sources and types and allow it to chose what it believes is best? How would this look? If you simply did: <img src-options="image.

People screw up. The people working on Chrome for iOS didn't mean to break WebP support, and when they discovered this they fixed it in the next revision. They're already plenty motivated and on top of things. It doesn't ma

I work on PageSpeed, which makes heavy use of UserAgent string parsing. I would love to stop using the UA and just leave everything up to the browser, but you can't do that without slowing things down. They key problem is we need to

That would be a huge scandal. When fraudulently issued certs are discovered that's news, and if you did get one issued you wouldn't use it to redirect random BT customers to http.

I looked into car helmets a few years ago [1] and my takeaway was that in older cars helmets would have helped, but cars made in the last 20+ years have enough interior padding and airbags that helmets wouldn't add much if anything. If
