Snow Unix Event - 12 & 13 april 2018

picture

In april 2018 verzorgen wij de 6e editie van het Snow Unix Event, kortweg SUE, op ons kantoor in Geldermalsen. SUE faciliteert al jaren de kennisdeling tussen toonaangevende experts en technische specialisten op het gebied van Unix en Linux. Tijdens SUE zal de uitwisseling van kennis centraal staan. De programma's van donderdag en vrijdag zijn vrijwel identiek.

Een impressie van het afgelopen SUE vind je op https://sue2017.snow.nl net als de presentaties.

Michael Steil & Christian Hessman

Biography

Michael Steil likes to call himself a computer historian, but is really just a software engineer that likes old computers. His blog at pagetable.com mainly deals with what we can learn from the old times.
Christian Hessmann likes to call himself a Rocket Scientist, but never actually sat on a rocket. He spends his days managing engineers and scientists doing actual rocket science.

Abstract

The Apollo Guidance Computer ("AGC") was used onboard the Apollo spacecraft to support the Apollo moon landings between 1969 and 1972. This talk explains "everything about the AGC", including its quirky but clever hardware design, its revolutionary OS, and how its software allowed humans to reach and explore the moon.

The AGC was an early digital computer specifically designed for the Apollo moon missions. The Command Module and the Lunar Module each contained one AGC. First built in 1965 from 5600 integrated circuits, it was one of the first minicomputers, beating commercial machines like the PDP-8 in weight (32 kg) and power consumption (55 W). The Apollo program's size and weight limitations as well as the requirements for real-time guidance, navigation and control were pushing 1960s technologies to their limits. As a 15 bit one's complement big-endian accumulator machine with 36 kilo-words of ROM and 2 kilo-words of RAM, its design seems very foreign from today's perspective. The operating system was real-time, priority-based cooperative/preemptive and fault-tolerant, supporting interpreted virtual machines – practically inventing many of these concepts.

This talk explains all the hardware details of the AGC: Its machine language, counters, timers, I/O, display and keyboard, as well as its implementation using integrated circuits, core memory and "core rope" ROM. The talk goes on to explain the software: interrupt handling, the core set, the wait list, the alarm system, the interpreter, and the actual user software, providing, among other things, guidance, navigation and control (GNC) services.

The audience will get a good understanding of hardware and software design in the 1960s, and appreciate the innovations driven by the Apollo program

Dan Walsh

Biography

Daniel Walsh has worked in the computer security field for over 30 years. Dan is a Consulting Engineer at Red Hat. He joined Red Hat in August 2001. Dan leads the Red Hat Container Engineering team since August 2013, but has been working on container technology for several years. Dan has made many contributions to the docker project. Dan has also developed a lot of the software on Project Atomic. He has led the SELinux project, concentrating on the application space and policy development. Dan helped developed sVirt, Secure Virtualization as well as the SELinux Sandbox back in RHEL6 an early desktop container tool. Previously, Dan worked Netect/Bindview's on Vulnerability Assessment Products and at Digital Equipment Corporation working on the Athena Project, AltaVista Firewall/Tunnel (VPN) Products. Dan has a BA in Mathematics from the College of the Holy Cross and a MS in Computer Science from Worcester Polytechnic Institute. For more on Dan see @rhatdan on twitter or his blog.

Abstract

This talk explains the key components required to run a container image on a host. Standardization of the format. OCI Image Format:

Once we have these standards we can start examining technologies that can take advantage of these standards for doing things like:

Scott Long

Biography

Scott works together with Drew Gallatin at the Netflix’s Open Connect CDN group. They focus on improving FreeBSD kernel CPU efficiency on Netflix's CDN.

Abstract

Netflix can serve over 90Gb/s of TLS encrypted media content from a single socket Intel Xeon based Open Connect Appliance. Netflix does not use hardware offloads like TOE or hardware TLS accelerators; all traffic flows through the kernel via sendfile. The presentation will give a detailed account of Netflix's journey from serving content at less than 40Gb/s unencrypted to over 90Gb/s fully encrypted, and will take a deep dive into the FreeBSD kernel bottlenecks that we encountered and how we overcame them.

Ben Gras

Biography

Ben Gras has been in the VU systems security research group since 2015. He has worked on software reliability, security defensive research, and most recently, offensive research projects. Defensive research has included a CFI solution and a router malware detection system. Offensive research was most noticeably making cross-VM Rowhammer exploitation reliable and a cache-based MMU sidechannel attack. Before his tenure as a security researcher he spent many years as a systems programmer on the MINIX 3 project, known nowadays as used by Intel in their chipset platform.

Will be added soon

Abstract

Migrating a 230 TB Elasticsearch cluster from version 2 to version 5 with minimal (max. 30 minutes) of downtime.
