Toward a smarter OOM killer

,----[ Quote ]
| The Linux memory management code does its 
| best to ensure that memory will always be 
| available when some part of the system needs 
| it. That effort notwithstanding, it is still 
| possible for a system to reach a point where 
| no memory is available. At that point, 
| things can grind to a painful halt, with the 
| only possible solution (other than rebooting 
| the system) being to kill off processes 
| until a sufficient amount of memory is freed 
| up. That grim task falls to the out-of-
| memory (OOM) killer. Anybody who has ever 
| had the OOM killer unleashed on a system 
| knows that it does not always pick the best 
| processes to kill, so it is not surprising 
| that making the OOM killer smarter is a 
| recurring theme in Linux virtual memory 
| development.


Linus Torvalds - Time for a Nobel Peace Prize?

,----[ Quote ]
| That list of Linux-related or -inspired 
| developments is only partial. Here in the 
| Northwest, for example, we could add the 
| Free Geek operations in Portland, which do a 
| lot of good for not only the low-income 
| people and non-profit groups they are 
| specifically aimed to help, but also almost 
| everyone who comes into contact with them. 
| The effects though have been world-wide, and 
| are accelerating. And could grow faster with 
| a little more attention.



Three Economic Nobel Laureates In A Row Recognizing Power Of Infinite Goods

,----[ Quote ]
| With the Nobel Prize in Economics being awarded to
| Elinor Ostrom (as well as Oliver Williamson) this
| year, plenty of people are noting that Ostrom's
| seminal work has to do with how the concept of
| "the tragedy of the commons" isn't really true in
| many cases, and how that "commons" can often self-
| regulate itself. And, Ostrom definitely recognizes
| how this applies to the "commons" that is the
| public domain. I didn't want to comment right away
| on this. While I've read Ostrom's work in the
| past, I wanted to revisit some of it, to refresh
| myself on it.


I never won a Nobel Peace Prize.

,----[ Quote ]
| I woke up on the morning of October 9th to
| find that President Obama had won the Nobel
| Peace Prize.
| There was a lot of discussion about whether
| President Obama had "earned" the honor or
| not, and a lot of discussion about how the
| Nobel Peace Prize is not always for what
| you have done, but encouraging you to keep
| going in what you are doing.
| As I read his acceptance speech, I thought
| about Free and Open Source Software, and
| applied parts of his speech to my favorite
| subject.
| "Let me be clear, I do not view it as a
| recognition of my own accomplishments"
| A lot of people have said to me, "Thank you
| for what you do for Free Software". I tell
| them that I was someone who was in a
| particular place at a particular time. I
| did what I thought needed doing, and what I
| had skills to do.
