The program of the Linux Piter 2016 conference , which will be held on November 11-12 this year in St. Petersburg, is 95% formed. This year Linux Piter has a lot more English speakers than it did last year, and the topics are perhaps even more interesting.



The subsections of the conference are organized as follows:

• Firstly, these are presentations, one way or another connected with the Linux kernel - 5 pieces, including two reports on energy management.
  
• Secondly, containers and clusters - 3 reports, including a review presentation on easy virtualization and a report on creating your own industrial PaaS on the knee of improvised components.
  
• Thirdly, a couple of speeches about embedded systems with a detailed story about the device of a modern debugger.
  
• Then there are 3 topics about networks, including an explanation on the fingers of bottles what buffer bloat is and a news story in the TCP / IP stack.
  
• And at the end, a little DevOps with tools for measuring system performance and the admin panel.
  

Under the cut a little more ...

Linux kernel

• “ So you want to write a Linux driver subsystem? ”- Michael Turquette (BayLiber, President and CEO, USA) from Los Angeles will talk about how to and how not to design and write the perfect framework for the new driver subsystems in Linux. Anyway, how to write drivers competently.
  
  
• “ Let's talk about NVMe over Fabric ” - Sergey Platonov (RAIDIX, Department Head, St. Petersburg). A detailed presentation on the possibility of building SAN systems based on NVMe over RDMA, support for which appeared in the 4.8 kernel. Comparison with traditional technologies, test results in numbers.
  
  
• “ The quest for low latency with block I / O ”. A report by Paolo Valente (Universita di Modena e Reggio Emilia, Assistant Professor, Emilia) from Italy is devoted to using the well-known BFQ I / O scheduler to overcome the limitations of the I / O stack blk-mq for some types of loads.
  
  
• “ Introduction to Power Managemen t”, again by Michael Turquette. Mike has vast experience working with SoCs in Texas Instruments and in developing new smartphones, so we decided to ask him to read the report on the state of affairs in modern power management, since this topic is familiar to him from top to bottom.
  
• “ PowerCI.org: the product development CI loop based on kernelci.org .” Paired to the previous report by Benoit Cousson (BayLibre, Co-Founder, President & CTO, Nice), colleagues of Mike from France, about how to build a system for measuring energy consumption and what to do with the obtained metrics.

Containers and Clusters

• “ These containers were given to you! " Report by Pavel Emelyanov (Virtuozzo, Architect, Moscow) on the place of containerization in IT, on the "competitors" of this technology and what awaits it in the future.
  
  
• “ High Aavailability on Linux: Pacemaker's problems and what we do with them .” The report by Victoria Cherkalova (Dell EMC, Senior Software Engineer, St. Petersburg) will be about problems associated with the automatic configuration and performance of the most common cluster manager, and how to get around them.
  
  
• “ How to make PaaS using Docker, Consul, and Python bindings .” Presentation by Konstantin Nazarov (Parallels, Infrastructure Team Leader, Moscow) on how to make small PaaS for your company based on Docker, Consul and Python bindings as an orchestra.

Embedded

• A report by an engineer at ARM Pawel Moll (ARM, Principal Engineer, Cambridge UK) about Linux debuggers will be equally interesting for those who work with embedded systems and PCs. This is about how the modern debugger is arranged and what mechanisms it uses.
  
  
• “ LEDE is the most affordable embedded Linux distribution .” Alexey Brodkin (Synopsys, Senior Software Engineer, St. Petersburg) will talk about the details of the configuration and boot mechanisms of one of the OpenWRT derivatives on various platforms.
  

Network

• “ How Linux beat Bufferbloat ” - Stephen Hemminger (Microsoft, Principal Software Architect, Portland USA). A fun presentation about what Bufferbloat is literally “buffer swelling” associated with excessive buffering in the network stack, and how it is fought in the Linux kernel.
  
  
• “ Linux network report ” - Stephen Hemminger. Since Stephen is the official Linux maintainer of Linux bridging and iproute2 utilities and can easily talk about new features, drivers and new problems in the Linux TCP / IP stack, we asked him to report on this topic as well.
  
  
• “ Tempesta FW: yet another Linux kernel Web-accelerator ” - Alexander Krizhanovsky (Tempesta Technologies, CEO, Moscow). Presentation about the hybrid Web-accelerator and firewall, designed to filter large amounts of HTTP traffic. A story about why it is needed, how it is built, and why other solutions are not suitable.
  

Storage

• “ Linux IO internals for database administrators ” - Ilya Kosmodemyansky (PostgreSQL-Consulting, CEO and consultant, Saarbrücken Germany). This time Ilya will talk about how I / O in Linux works, how pages from databases travel from disk to shared memory and vice versa, and what mechanisms exist to control this process.
  
  
• “ The experience of replacing XFS with BlueStore in Ceph ” - Maxim Vorontsov (Engineer, Moscow). Ceph BlueStore should already be stable, and in 2017 - become the default backend, so Maxim has a story about the experience of migrating from FileSystem Backend to BlueStore.
  

Devops

• “An application well supported in production ” - Nikolay Sivko (okmeter.io, Co-founder, Moscow). Talk about what to do so that the above application is easy to support for people who did not write it. What is needed for transparent application operation in production? What is and what is missing in well-known metric collection systems.
  
  
• “ How devops exhausts himself, and what will happen next ” - Cyril Evenings (Jetware, CTO, St. Petersburg). A provocative title, and a report on what will happen next with DevOps, about the next generation of models for designing and operating server applications in public clouds and on classic servers.
  
  
• And finally, Alexander Chistyakov (DataArt, Chief Engineer, St. Petersburg) with traditional annealing!

There is more than a month before the conference, and we still have a couple of free slots for super-interesting reports. If your topic falls into the subject (and especially if it is about networks and storage systems), then we will be happy to accept your application for consideration.
