Now we just need to persuade +Jonathan Corbet​ to read them 😉

I did a write-up on some of the fun we had implementing Kernel Live Patching for powerpc.

#linux #powerpc
As part of the 4.6 and 4.7 development cycles, several of us from IBM & SUSE finally got all the pieces lined up to enable kernel live patching for ppc64le. If you're not familiar with kernel live patching, there's a pretty good write-up at Wikipedia. But the basic idea is that you can, ...

I can not believe they redesigned hangouts but continued with a design where 2% of the screen space is occupied by useful content.

Seriously what the hell.

Interesting article on server design from Facebook. In particular the fact that they went with single chips to remove "the NUMA problem" and this observation (assertion?) on single threaded performance:

"Dropping the TDP below 65W dropped the performance per CPU to unacceptable levels. This is one of the reasons why Atom-class processors have not gained a foothold in large-scale distributed workloads."
The new design packs more than twice the compute capacity into each rack while maintaining the rack power budget.

Sorry to see Intel get sucked in by this stock market bull■■■■.

Intel Corp. will eliminate 12,000 jobs, or 11 percent of its workforce, embarking on the deepest cutbacks in a decade to gird for a fifth year of declines in the personal-computer market.

Google have taken their sweet time reopening edits on map maker, but it looks like it will be for the best. They're proposing that most edits will not be moderated by the Google moderators. That will be a big improvement, as they were often just a pain and I'm sure drove a lot of potential editors away. So +1 !

The rotting foundations on which OpenStack is built ... :-/
The underlying issues leading to pull requests #64 and #65 suggest to me that slp_switch has potential to be compiled buggy when undefined compiler behaviour changes. Specifically: The gcc manual says: "Note that the compiler can move ...
