Linux Piter # 3: what about this time?
This week ends with the formation of the program of the third international conference Linux Piter , held with the support of Dell EMC.
These are two full days, November 3 and 4, Friday and Saturday in St. Petersburg, filled not with any husk, but with full-fledged reports about the network, system resources, containers and interiors of the Linux kernel. A purely technical subject matter is of interest to all those who use open source products and top technologies around Linux every day in their work and in their projects.
')
In short, we have 3 reports about the grid, 5 about containers, 4 about the core, a couple about performance and many more. So that the level of performances is clear: among the speakers from the States, Germany, Sweden, Austria and of course Russia, Lennart Poettering (systemd manntaineer) and Christoph Hellwig (XFS mantoiner and NVM Express driver) will come to us - this is really cool. There will be reports of engineers working in Redhat, Intel, Microsoft (!), Ericsson, Docker and Canonical. There will be two parallel streams from ten in the morning until the evening: the language of the speeches of the first stream is English (with simultaneous translation into Russian for those who don’t have time), the second one is Russian (with synchronous into English for our foreign guests).
Below are a few announcements of speeches in different sections of the conference.
A nice feature of Linux Piter # 3 is that at the same time on the same site another one of our technical conferences will be held - Piter Py # 4 , and participants will be able to attend reports of either of these two conferences freely.
So, “what is the Linux Piter conference about this time?”
Christoph Hellwig, Austria, Innsbruck, self employed
Failure-Atomic file updates for Linux
Discussion of the new atomic update mechanism for crash-resistant XFS files. Its implementation would avoid proprietary implementations of mechanisms that ensure data integrity, for example, for databases.

This is basic, but not all. Last year everyone liked it, it was a day and a half and about two hundred people, this year it will be even better - two full days and more participants! There are no free slots for reports, but there are still tickets, registration and a detailed program on the conference website: www.linuxpiter.com
Traditionally, we plan to record and upload videos of all reports, but as in previous years, we will do this gradually. To miss nothing, subscribe to the Linux Piter youtube channel .
