Eind maart organiseerde Snow wederom het Snow Unix Event, kortweg SUE. Sprekers uit binnen- en buitenland hebben de zeer technische onderwerpen tot in detail behandeld. Een impressie van SUE 2015 vindt u hieronder.
Sprekers bewegen dynamisch door hun verhaal door het kennisniveau en vragen van de aanwezigen. De gewenste interactie door Christopher Lameter met vragen vanuit het publiek
Sprekers, specialist op hun vakgebied, nooit verlegen om een extra sessie te geven! Andrew Gabriel geeft extra uitleg
Het Snow Unix Event werd gehouden op 26 en 27 maart 2015 in ons pand te Geldermalsen.
|09.30-10.30||Jon "Maddog" Hall:
Keynote; The Evolution of Free Software
Online kernel patching
Less known and new OpenZFS features
Linux memory allocation mechanism
Linux Branded Zones on SmartOS
Informatie over onze sprekers, hun achtergrond en onderwerp zijn in het Engels opgesteld.
The nickname "Maddog" was given to him by his students at Hartford State Technical College, where he was the Department Head of Computer Science. He now prefers to be called by this name, which according to Hall "came from a time when I had less control over my temper". Hall has used his experience and name recognition to promote a variety of causes, generally involving open source hardware or software in some fashion.
Many people who were raised in the era of the "PC", whether powered by Microsoft or Apple software, think that the Free Software movement is new, and that it came about through the efforts of either socialists or hippies. In reality Free Software has existed since the dawn of computing in one form or another, and in reality it is proprietary software that is the newcomer, and is now slowly losing ground. Unix systems have existed since 1969, and this venerable and flexible operating system continues to live on in distributions such as the BSD-derived versions, GNU/Linux and Android. Learn (or travel down memory lane) with Jon "maddog" Hall, to see how this all ties together and why Free Software ('Free as in Freedom, not Free as in "Free Beer"') will continue to be the wave of the present and future. You will never look at proprietary software the same way.
Vojtech Pavlik is a Director of SUSE Labs, a global team within R&D at SUSE focusing on furthering core Linux technologies. In his kernel developer past, he has worked on USB support in Linux and created the Linux Input subsystem. He enjoys solving interesting problems that Linux faces, recently proposing the MOK concept as a solution for UEFI Secure Boot on Linux.
SUSE Labs has developed and released (GPLv2 for Linux kernel and GPLv3 vfor GCC) a new technology for live patching of the Linux kernel, allowing for easy deployment of kernel updates without a reboot. Unlike previous implementations of this functionality, kGraft doesn't require the kernel to be stopped, and is using existing kernel infrastructure for most its work.
Dr. Christoph Lameter is working as a lead in research and development for an algorithmic trading company in Chicago. He is a long term contributor to the Linux kernel and maintains the slab and the per cpu subsystems. As the Principal Engineer for kernel development at SGI he pioneered the use of Linux on Supercomputers and developed the necessary kernel capabilities for extreme high performance applications (2004-2008).
Slab allocators are providing memory allocation to kernel code. Often these allocations may occur in performance sensitive code (especially in the network and storage layer). Kernel performance is significantly affected by the slab allocators architecture and features. The talk provides an overview of the slab allocator services available in the Linux kernel and covers the most frequent use cases. The approaches used in the three slab allocators (SLAB, SLUB, SLOB) are compared and ways to get the maximum performance out of each of them are presented. Lastly a series of common gotchas when using slab allocators are reviewed followed by an open discussion on issues and the future of the slab subsystems.
Max Bruning began using and programming Unix-based systems while obtaining a Master's degree at Columbia University in the mid 1970's. He has been teaching Unix Internals, Device Drivers, and various other courses since 1981. Max has also spent many years doing kernel development, device driver work, and debugging work, mostly on SVR4-based systems.
He has done consulting and/or training work for Bell Labs, AT&T, Motorola, Sun Microsystems, HP, Siemens-Nixdorf, and various other companies. Max has had articles published on device drivers, ZFS, Solaris/Linux/Freebsd kernels, and application programming on Solaris and Linux. In September, 2010, he started porting Linux KVM to SmartOS for Joyent.
This talk will describe the current state of Linux Branded zones (LXz). It will start with a brief history, followed by a description of the problems LXz can solve. We shall then walk through a live demo to show some of the features of running LXz. The talk will conclude with a discussion of the implementation, and a look at what's coming.
Andrew has worked in the computer software industry for over 30 years on operating system and application design. Andrew was part of the Solaris Kernel development team during Solaris 8, 9, and 10, and one of the original developers of Solaris Zones in Solaris 10. More recently, Andrew has been working with customers on the design and deployment of storage servers and storage appliances, based on ZFS.
The ZFS filesystem, originally developed at Sun Microsystems, is seeing a rapid growth to many operating system distributions and appliances. Andrew will talk about some of the newer features and enhancements in ZFS implementations, and work in progress which will be upstreamed in the future.
