The Internet Archive recently put a ton of 70s and 80s arcade games on the web, ready to play in the browser. W00t!

Today we launched a US update of Google Flu Trends - yay! The Centers for Disease Control estimate that a severe flu season claims as much as 49,000 lives in the US - more than the number of people killed in traffic accidents every year. So get your flu shot, and stay healthy (and thirsty), my friends!
When people get sick, they turn to the Web for information. Back in 2008, a team at Google dug into this behavior and found that certain search terms were good indicators of flu levels. We later launched Google Flu Trends to estimate flu activity in near real-time using aggregated Google search ...

The video from David Sehr's excellent talk on using Portable Native Client is now available. Get PNaCl before your neighbor!

We just made a (wider) announcement of Native Client support on ARM. W00t!

Cool. Looking forward to try it out.

Developing for Native Client using a trusted plugin? Here are some pointers for debugging out-of-process plugins in Chrome 25 and later with Visual Studio.

Play Amiga games in Chrome! Check out our latest Portable Native Client technology demo: an Amiga emulator running in Chrome. Now you can play the good old Amiga games directly in the browser. Portable Native Client is supported in Chrome on Windows, Mac, Linux, and Chrome OS. Cloanto kindly provided the ROMs and disks for this demo, and also put together a Chrome Web Store app (Amiga Forever Essentials) in record time (thanks guys!) You can run the Amiga in full-screen and even connect a USB gamepad.

The emulator code is based on the Open Source Universal Amiga Emulator which is about 400k lines of C code, which were ported to Native Client. All the code is available in Open Source for anyone interested in porting their own C/C++ code to the web.

I too appreciate the Amiga emulator.  I had a 1000 back in 1987 and fondly recall many, many Amiga games, utilities and demos.  It was truly an amazing computer!  Thanks for the effort and to Cloanto for the help!

I am extremely proud to announce that I have joined the board of One World Children's Fund. One of the many things I love about this organization is that you can donate directly to any of our more than 30 partners and know exactly to which school, orphanage, etc. your donation goes. If choosing is too overwhelming :-), general donations are extremely welcome, as they let us send the money where it's most needed and support the magic that makes all the partner projects possible. Please donate generously!

PNaCl is getting closer...
 
Introducing Portable Native Client (PNaCl)

Native Client lets developers run native compiled C and C++ code in their web apps.  With Native Client, developers can leverage existing code bases and realize the performance benefits of compiled code on the web.

In a talk at I/O, +David Sehr provided an update on the status of Native Client and discussed the next step in the evolution of this technology: Portable Native Client (PNaCl, pronounced "pinnacle").

PNaCl enables applications that are truly architecture-independent. Developers create a single executable; Chrome then translates the executable for specific end-user architectures, including x86 and ARM.  Once PNaCl is fully released, users will be able to run PNaCl modules on any web page (applications will not need to be deployed through the Chrome Web Store).

From all of us to all of you: one more set of tips and pointers if you're porting something to Native Client. TL;DR: in Chrome 25 you can make Pepper calls from any thread! #NaCl #NativeClient
