It's an event of historical magnitude: One of the most popular Open Source projects, LibreOffice, is now available directly from Apple's Mac App Store. You can get LibreOffice on OSX with automatic updates, long-term maintenance, and optional professional support, for the first time.

Awesome! #Chrome improving battery friendliness :)
 
One of the big complaints about Chrome currently is that it's a battery hog, especially on Mac where Safari seems to do better.

The team has been working on addressing this; here are some cases that have recently been improved on trunk:

http://crbug.com/460102

Before: Renderers for background tabs had the same priority as for foreground tabs.
Now: Renderers for background tabs get a lower priority, reducing idle wakeups on various perf test, in some cases by significant amounts (e.g. 50% on one test).

http://crbug.com/485371

Before: On a Google search results page, using Safari's user agent to get the same content that Safari would, Chrome incurs ~390 wakes over 30s and 0.3% CPU usage vs. Safari’s 120 wakes over 30s and 0.1% CPU usage.
Now: 66% reduction in both timer firings and CPU use. Chrome is now incurring ~120 wakes over 30s and 0.1% CPU use, on par with Safari.

http://crbug.com/489936

Before: On capitalone.com, Chromium incurs ~1010 wakeups over 30s vs. Safari's ~490 wakes.
Now: ~30% reduction in timer firings. Chrome is now incurring ~721 wakeups over 30s.

http://crbug.com/493350

Before: On amazon.com, Chromium incurs 768 wakups over 30s and consumes ~0.7% CPU vs. Safari's 312 wakes over 30s and ~0.1% CPU.
Now: ~59% reduction in timer firings and ~70% reduction in CPU use. Chrome is now incurring ~316 wakeups over 30s, and 0.2% CPU use, on par with Safari at 312 wakes, and 0.1% CPU use.

The Chrome team has no intention of sitting idly by (pun intended) when our users are suffering.  You should expect us to continually improve in this area.

Please share this around.

In the BSDCan 2015 keynote, Steve Bourne will talk about about sh/adb which he has never covered before in public. These include:

* sh memory management and interfaces used to interleave heap and stack these were not C stack
* sh has no string length or any other "arbitrary" length restrictions and what that meant for
implementation
* sbrk and porting grief people had (things you dont think of when you write the code)
* my opinion of shellshock
* tricks used and why (eg using top bit of byte as quoted string marker)
* reasons we did all this and wouldn't do it today
* adb interesting problem it runs on one machine is debugging another and compiled on a third
* why i wrote it (Algol68 port) and Dennis added overlays (exec)
* invention of environment variables and why
* How I talked Dennis into putting 'void' into C and other C changes
* why setjmp and longjmp are a good idea (so I could write sh)
* why Bill Joy wrote the C shell

Good quality food, fresh and very well cooked. Slightly on the pricey side for what it is

Very high quality food. Seafood soup is brilliant, butterfly shrimp is awesome, and fish is great. Prices slightly above average though

Had my broken side-mirror repaired there for my Skoda Octavia. Very quick and professional. They definitely get the job done, but don't go the extra mile

Very poor quality! Staff and their management don't know how to treat customers. I tried once, twice and three times, and was always disappointed. Consider going to baity? Don't! Go elsewhere
