What CPU executes single precision floating point values at the same speed as
double precision?
Here's a benchmark from NASA giving a comparison of single vs. double precision
performance for one of their simulations.

Subtraction of two points should not equate to a size. That's would be
unexpected behavior for anyone used to working in 2D space. Mathematically
speaking point - point equates to a vector. When writing a vector math library
there typically isn't a differentiation made between a point and a
I was wondering who was in charge of WinCairo now. We at Sony have been using
WinCairo to land anything that isn't specific to our own internal port but we
don't have any intention to ship anything using it.
We have some outstanding patches for the GitHub requirements repository,
@annulen I know you've mentioned conan.io before but I've never personally used
it so I'm not sure how well it would fit with everything. It's something we can
take a look at beforehand and see what it would take vs the single repository
setup.

I went that route. We at Sony are newcomers to pushing to trunk so my
explanation might be entirely too idealistic but here goes.
I had thought of PAL as a library that is internal to WebCore that provides a

There was a commit, https://trac.webkit.org/changeset/220139/webkit ,
referencing a Buildbot 0.9 dashboard. I'm wondering if we need to upgrade our
setup to 0.9 and if so what the timeframe is for the upgrade.

Hi WebKittens,
We over at Sony have been committing more resources to WebKit, from
revitalizing the WinCairo port, rebooting the cURL network backend, and
continued work on the PAL layer. We've had some developers looking at the
possibility to move WinCairo from WebKitLegacy over to WebKit and
Web Audio is on the radar for WinCairo. I wasn't going to start working on it
until after platform/audio ended up in PAL.

I'd like to begin an implementation of CSS Typed OM (CSSOM) and wanted to gauge

CSSOM provides typed style access to improve performance by removing the need

I took some time today to see how clang-tidy can be run on WebKit code and

be applied.

The same images should be fine for AppleWin but it's not something I've tested.

Hey all,
As we mentioned during the contributors meeting we want to work towards
fleshing out the PAL library. We have the cycles to really start rolling on it
but are hitting some issues we wanted to run by the community.
Currently the obvious stuff to move over into PAL, network, graphics
Did you happen to look at any sort of distributed build system? We use
distributed builds here for WebKit and a full rebuild is pretty reasonable.
That would negate the need to change how everything is done to get a unity
build going.

There are a couple problems with checking in a version of ICU.
* Other libraries used by WebKit have dependencies on ICU. For our ports
harfbuzz, libxml2, libxslt, libpsl and CFlite all require ICU.
* ICU doesn't come with a CMake build system and its non-trivial to make one.
