At the last USENIX/LISA conference, I gave a talk on new Linux performance tools: my open source perf-tools collection. These use existing kernel frameworks, ftrace and perf_events, which are built in to most Linux kernel distributions by default, including the Linux cloud instances I analyze at Netflix.
Almost two years ago, we closed out our review of Dell’s first Linux-powered Developer Edition laptop with some words of wisdom from my former uber-sysadmin mentor, a fellow named Rick, with whom I worked at Boeing for many, many years. Rick is now retired and living the life of an itinerant world-traveling SCUBA master, but he’s been hacking on Linux since around the time Linus first dropped the kernel on comp.os.minix. I lamented to Rick that I was having a hard time coming up with an angle or hook for the XPS 13 Developer Edition, because it all just worked—Dell got it right, and it was a great piece of kit. It was maybe even a bit boring.
Much like the Linux kernel development process itself has evolved as a function of development, I suspect the code of conduct will be the same. That is to say it will be self-regulating without some kind of rigid system of policies.
The simple truth is that the vast majority of Linux kernel development is done by those that work for companies. Since LKML is all in the open, and it's clear to see who works for whom, I suspect that various corporate masters already have policies in place as well.
The Community School of Excellence Asian Penguins start every club meeting with a call and response.
The meeting leader, always a kid, asks the question, "What are we trying to do?" and the kids respond, "Change the world!" The leader then asks, "How do you change the world?" and the kids then respond, "Be crazy enough to think you can!"
What are the Asian Penguins? That's a simple question that has a complicated answer. Are they a student club? Yes. Are they a tech support group that takes care of some of our school's computers? Partly, yes. Are they also a movement for change that challenges our students to improve people's lives through the power of open source technology? Most definitely, yes. Simply put, the Asian Penguins are a Linux users group.
Bodhi Linux provides options to download 32-bit, 64-bit, legacy and Chromebook version. I chose 64-bit ISO, about 612 MB in size. I created a live USB using Linux Mint Image Writer on a 4 GB USB drive. First I did a live boot on my laptop and then installed it to a 100 GB drive to understand Bodhi's performance better.
The ext4 filesystem causes a number of scaling and performance issues which Jan Kara, Linux kernel engineer at SUSE, addressed in his presentation at The Linux Foundation’s Vault storage conference last week.
Ext4 represents the latest evolution of the most-used Linux filesystem, ext3. In that regard, ext4 can be considered a deeper improvement over ext3 than ext3 was over ext2. (Ext3 was mostly about adding journaling to ext2.)
Imagination Technologies is a British company that has recently entered full production of a board based on MIPS computer architecture. The single-board computer has been designed to allow developers to create applications for mobiles, gaming, Internet of Things, and wearables.
The MIPS Creator CI20 is billed as a high-performance, fully featured Linux and Android development platform. The board includes an Ingenic JZ4780 SoC which is built around a dual-core MIPS32 processor clocked at 1.2GHz, and Imagination's PowerVR SGX540 GPU. The Creator CI20 comes with a price tag of or £50, which is significantly more expensive than the Raspberry Pi 2. CI20 is an open platform with technical manuals, schematics and source code freely downloadable. You might be interested in my Raspberry Pi 2 review together with this article.
