Wow. Has anyone heard about buffered writes ? And does kernel-level page cache ring a bell ? No fsync was ever used in the benchmarks, therefore, it is never actually hitting the disk. The only good thing about this paper is that the Java and Python listings are available at the end, for everyone to identify the basic flaws in this research.
So yeah, it's faster to write directly to MEMORY than to do a copy before writing to MEMORY.
Just a random though: has anyone checked how long, and over what distance, the plane could fly from its cruise altitude once its engines stop ? If, in such a situation, the pilots tried something similar to what has been done with flight 1549 (https://en.wikipedia.org/wiki/US_Airways_Flight_1549), it might be an interesting approach to try to approximate a circular search zone (rather than an area).
So far, LTTng has been mainly integrated in embedded distros: WindRiver Linux, Montavista Linux and STLinux currently ship with LTTng. The interesting news that is particular about Ubuntu here is that, by installing the LTTng packages from PPA, it is now possible to easily deploy the LTTng kernel and userspace tracers on a desktop-oriented distribution.
The K42 project at IBM Research investigated the benefit of a complete OS rewrite with scalability to very large SMP systems in mind. This is an open source operating system supporting Linux-compatible API and ABI.
Their target systems, "next generation SMP systems", back in 2003 seems to have become the current generation of SMP/multi-core systems in the meantime.
Not only does the WIPO influences copyright laws, but it does also affect the patents, which is exactly the point that the GPL v3 plans to take care of.
It's good to have an organism like the FSF being recognised in the, how critical, field of intellectual property!
It seems that while the lastest security hole found in OpenSSH is not fixed, the ISS and OpenBSD people try to keep the details of the problem for themselves.
This method is maybe good for a short time, but I hope this will be fixed soon.
If it takes "it 3 months to simulate the first 1/100th of a second of a nuclear bomb explosion." Well, I'd say : there is nothing like the old good nuclear explosion of our grandfathers;)

Just one word : gory !

We could have saved up to 70% on Term Life Insurance! Dammit!

I can say that this popup is at the right place
