We celebrate the 24th birthday of Linux by looking back to it’s early days, discuss the new SSD optimized Linux file system, the rather normal things Linux is doing on Mainframes & how the community at large reacts to crowdfunding.
Plus some great follow up, some great discussion & much more!

Canonical Kills Desktop Ubuntu Software Center, Focuses on Mobile Apps
Desktop apps stores are dead, and their mobile-oriented equivalents are the future. That’s the message from Canonical, which has quietly made clear that it intends to jettison the Software Center in Ubuntu Linux to focus on mobile apps for Snappy Ubuntu Core.

How Linux was born, as told by Linus Torvalds himself | Ars Technica
It has been 24 long years since the first ever release of the Linux project on August 25, 1991, which is the core component of any GNU/Linux distribution. With this occasion we want to remind everyone that Linux is everywhere, even if you don’t see it. You use Linux when you search on Google, when you use your phone, when buy metro tickets, actually the whole Internet is powered by Linux. Happy Birthday, Linux!
A New Linux File-System Aims For Speed While Having ZFS/Btrfs-Like Features
This new file-system is Bcachefs. BcacheFS is based on _BCache, the Linux kernel block layer cache_for pairing a large-capacity hard drive with a low-capacity, high-performance solid-state drive to act as a cache. In developing this block layer cache, Kent Overstreet (the primary Bcache/Bcachefs) developer realized they were basically writing their own file-system in the process. He explained, “the bcache codebase has been evolving/metastasizing into a full blown, general purpose posix filesystem – a modern COW filesystem with checksumming, compression, multiple devices, caching, and eventually snapshots and all kinds of other nifty features…I and the other people working on bcache realized that what we were working on was, almost by accident, a good chunk of the functionality of a full blown filesystem – and there was a really clean and elegant design to be had there if we took it and ran with it.”
PERFORMANCE:
I’m not really focusing on performance while there’s still correctness issues to
work on – so there’s lots of things that still need to be further optimized, but
the current performance numbers are still I think good enough to be interesting.
Here’s some dbench numbers, running on a high end pcie flash device:

IBM LinuxONE
IBM Fellow Donna Dillenberger demonstrates the new IBM LinuxONE system for scalable financial trading at the LinuxCon 2015 conference. The demo show multiple data loads (live data from the S&P 500 and Tweets) streaming via Maria DB, MongoDB, Spark Analytics, Chef, Docker and PostgreSQL.
In this LinuxONE demo, even with drastic upticks in CPU Utilization during the Greek financial crisis, response times are still lightning fast.

Open Source is about supporting those who support you.
But his most recent work is one that is of even more importance to everyone, even those that use Windows or Apple. NTP, or Network Time Protocol, is a fundamental component of our information society today. The NSF reached out to Eric and he’s taken up the task of recoding NTP. For more information read the post on his blog post: Yes, NTPsec is real and I am involved.
