I'm the TL for Google Compute Engine. This isn't the performance we expect here and we will be looking in to see what is going on.

I don't know about GAE specifically but I'd be very surprised if it didn't see the same time as the rest of Google. They would have had to do work to make that happen.

As part of Google Compute Engine we provide an NTP server to the guest which is based on Google Production time. As such our VMs get to take advantage of this leap second smearing implementation. I was going to mention this at my talk at IO

Exactly -- if you composite into a buffer without an alpha channel (such as the final frame buffer) you are cool. If you want the destination to be able to alpha composite further on, you have trouble/complexity.

You can probably blame me for this, to some degree. We were really trying to build for the future with WPF and as such wanted to be truly resolution independent. As such, we (I) locked a px to a 1/96th of an inch. The end result is that

Perhaps I'm not being clear. In WPF/Avalon we aimed to have a generic scene graph. We were also looking to cache intermediate nodes in the scene graph and do composition of a transform on those nodes. This was to prevent the need to compl

Interesting article -- but that assumes that you have both an RGBA source and an RGBA mask -- twice the RAM. When doing full screen compositing ram is a big deal. If you are rendering solid color text, the source could be a constant. But

We faced this issue when building WPF/Avalon ~7-8 years ago. One key here is that subpixel rendered text can't be easily composited. You essentially need RGB alpha channels so that you can blend each channel independently. Because of this

Actually, by the time it shipped, 80% of the crashes were due to insane reentrancy issues due to the componentized nature of IE. For example, when tearing down a page, we would go ahead and release the laster of the references to the Active

I implemented this in the core data structures for IE5. We were very memory constrained as we had to run on Win95 machines with something like 12MB of RAM. I was counting bits. The base level of the tree wasn't really a node DOM but rathe

I can guarantee that the snark is intrinsic to Raymond. He is just that type of guy. He loves a good story, is very sarcastic and likes to troll co-workers. (I could tell quite a few Raymond stories from when we worked together but it is be

This is addressed in the article. It says that google uses toolbar latency to determine page load latency and that is the only way toolbar data affects page ranking.

Performance improvements in modern browsers (V8 and webkit) along with more memory and faster processors are the game changers here. Keep in mind that at the time it was all based on the Trident rendering engine introduced in IE4. The syste

IE 5.5 had a lot of this with behaviors. IE 6 built on it further. Firefox push a lot of similar concepts with XUL. These ideas aren't especially new. There are a lot of subtlties that make this stuf really tricky. For details on behaviors

A trick to save memory: If you have a struct/class with a lot of members that are usually set to zero or some other initial value, you can store them in a "lookaside" structure that is hung off a global hash table with the pointer of the or

Having worked on IE back in the day, I can take a good guess as to why XP isn't supported. (I haven't had the time to read all of the reddit responses yet). It comes down to cost. Microsoft tests everything way way more than is apparent f

TCP connections are identified by the (src ip, src port, dest ip, dest port) tuple. The server only needs one port. So theoretically a server can handle 64k connections per client.
