From announce at lists.nycbug.org Mon May 4 00:03:09 2015 From: announce at lists.nycbug.org (NYC*BUG Announcements) Date: Mon, 04 May 2015 00:03:09 -0400 Subject: [announce] NYC*BUG May 6: John V on BitRig Message-ID: May 6 Bitrig, John C. Vernaleo 18:45, Stone Creek Bar & Lounge: 140 E 27th St Abstract Bitrig aims to be a free, fast, and secure Unix-like Open Source operating system focusing on modern hardware platforms only. Bitrig is a fork of OpenBSD and recently release version 1.0. I'll give a brief description of what the current status of Bitrig is, where we hope it fits in with the other BSDs, and why we think what we are doing is worthwhile rather than just contributing to an existing OS. I'll give some info on the current progress on Bitrig on ARM devices. Finally, I'll try to explain what our current relationship to the OpenBSD codebase is. Speaker Bio John is an astronomer by training who slowly moved from research to writing code for other people's research to writing code for finance all the way to writing code for startups (and finally to writing code for a BSD). He is a relative latecomer to BSD having previously gone from Solaris to Linux before becoming involved with Bitrig. He is still waiting for the day when his FORTRAN programming skills come in handy again. Other upcoming events. Location is Stone Creek unless otherwise noted. 2015-06-03 - FreeBSD's NUMA, John Baldwin BSDCan June 12-13 in Ottawa, Canada 2015-06-18 - mandoc: from scratch to the standard BSD documentation toolkit in 6 years, Ingo Schwarze (Location TBA) 2015-06-19 - Social event with Ingo Schwarze at Stone Creek 2015-07-01 - Staying in sync with the Precision Time Protocol, Steven Kreuzer 2015-08-05 - What's New with OpenBSD, Brian Callahan vBSDCon September 11-12 in Reston, Virginia EuroBSDCon October 1-2 in Stockholm, Sweden From announce at lists.nycbug.org Wed May 6 13:29:13 2015 From: announce at lists.nycbug.org (NYC*BUG Announcements) Date: Wed, 06 May 2015 13:29:13 -0400 Subject: [announce] NYC*BUG Tonight: John V on BitRig Message-ID: May 6 Bitrig, John C.

The YouTube video is up for John V's Bigrig meeting: https://www.youtube.com/watch?v=h4FhgBdYSUU ***** There are a lot of BSDCons this year, as we've announced, including BSDCan next month, EuroBSDCon, vBSDCon. Now BSDCon Brasil 2015 was just announced for October 9-10 in Fortaleza, Brazil. The CFP is open, and talks are accepted in Portuguese, Spanish or English. The FreeBSD hackers@ and OpenBSD misc@ post provides the full details in English: https://marc.info/?l=openbsd-misc&m=143110037410035&w=2 From announce at lists.nycbug.org Tue May 26 15:38:55 2015 From: announce at lists.nycbug.org (NYC*BUG Announcements) Date: Tue, 26 May 2015 15:38:55 -0400 Subject: [announce] NYC*BUG Upcoming Message-ID: For the first time in a long time, we will hold two meetings in a month, plus a social event, with BSDCan in between. Note: if you are going to BSDCan, please bring any HDMI-compatible LCDs for hardware hacking. There will be enough cables, but displays are greatly needed. June 3 - FreeBSD's NUMA, John Baldwin 18:45, Stone Creek Bar & Lounge: 140 E 27th St Abstract Newer x86 systems continue to scale horizontally by adding more cores rather than vertically. This in turn has placed additional strain on other system components such as memory controllers. The solution has been to scale these components horizontally as well. This results in a more complex system requiring additional tuning for optimal performance. The first part of the talk will provide an overview of these extra-CPU scaling changes in x86 systems. We will also talk about the resulting performance impacts and some of the tradeoffs to consider when tuning. The second part of the talk will focus on changes to FreeBSD to support these system changes both in past releases and anticipated work in future releases. Bring your facial tissues. The problems here are similar to those of achieving optimal performance on systems with multiple CPUs, and we all know how well that has worked out. Speaker Bio John first started using FreeBSD in 1996 and has been an active kernel developer since 2000. He has worked for various companies that use FreeBSD with a recent penchant for hacking on bhyve. John lives in New Jersey with his wife and three kids.
