Secondary-hardened bainite

Jer-Ren Yang
A lecture given by Jer Ren Yang, at the Adventures in the Physical Metallurgy of Steels (APMS) conference held in Cambridge University. The metallurgy of a new, microalloyed bainitic steel that is capable of secondary hardening, accompanied by a simultaneous increase in strength and ductility is introduced. Ideally, a low carbon bainitic microstructure offers an excellent combination of good toughness, strength and weldability. The typical microstructure of low-carbon bainitic steels is composed of a fine...

A lecture given by Tarashankar DebRoy, at the Adventures in the Physical Metallurgy of Steels (APMS) conference held in Cambridge University. Mathematical modelling of the friction stir welding of steels. In previous work, we have established a scheme that exploits a combination of three-dimensional heat and mass flow models, together with fast calculation algorithms and damage accumulation models, to assess tool durability and define the domains of satisfactory tool life in the context of welding...

Relocation of luminophores by macrofauna

Stina Lindqvist
Time-lapse video of images that illustrate 2-D redistribution of luminescent particles (luminophores) caused by particle reworking activities by benthic macrofauna during a two-weeks experiment. Please note that the relative timing on the video does not correspond to the timing when images were captured. 4 replicates for each treatment are shown for the species Nephtys incisa, Abra nitida, Nuculana pernula and Thyasira sarsii (video A), and Glycera alba, Lipobranchius jeffreysii, Scalibregma inflatum and Brissopsis lyrifera (video...

Runtime Process Infection (part 1)

Shawn Webb
This presentation will instruct participants on how to inject arbitrary code into a process during runtime. Writing malware on Linux isn't an easy task. Anonymously injecting shared objects has been a frightful task that no one has publicly implemented. This presentation will show how and why malware authors can inject shared objects anonymously in 32bit and 64bit linux and 64bit FreeBSD. The presenter will be releasing a new version of a tool called libhijack. libhijack...

Managing FreeBSD at scale

Allan Jude
Detailed discussion of ScaleEngine's production implementation of puppet on FreeBSD to manage many heterogeneous servers across the globe, with 70+ servers at 26 data centres in 10 countries deployed in a number of different roles (Web Hosting Cluster, HTTP Accelerator, HTTP CDN, Live Video, On-Demand Video, GSLB DNS) our needs cover a large swath of the capabilities of any management system. It is common for sysadmins to jump straight to cloud providers if immediate scale...

Call your NetBSD

Pierre Pronchery
After focusing on improving NetBSD support for tablet hardware, NetBSD enthusiast and DeforaOS developer Pierre Pronchery (khorben@) is working on running NetBSD on smartphone hardware, with the OMAP-based Nokia N900 as the main target. After a quick summary of the different steps taken, he will introduce the user interface, installation procedure and underlying specificities to this setup. If all goes well, he will even be able to give a call! NetBSD is a very portable...

Benchmarking FreeBSD

Ivan Voras
System optimization and tuning is tricky business. Benchmarking such systems is even more complicated as the number of things which can go wrong at doubles at the least. FreeBSD is best known for its killer features, but it also includes over 2500 sysctls, most of which can be tuned to do something interesting. This talk aims to give an overview of some of the more interesting things which can be tuned in FreeBSD, and advice...

Open Source Meets the Commercial World

Dan Langille & Eric Allman
Bambi Meets Godzilla: They Elope The world of open source and the world of commercial software intersect in profound and sometimes surprising ways. In some sense the two are like oil and water, but in other ways they can build on each other. This talk describes some of those differences — and ways they can enhance one another — using the sendmail open source mail transfer agent and Sendmail, Inc. as a case study.

Mozilla on OpenBSD

Landry Breuil
Maintaining the port of Firefox to OpenBSD is an interesting challenge, since the web & its related technologies are evolving faster and faster, and third-party OS are struggling more and more to keep up the pace with a fast-moving target such as Mozilla. I'll explain how i got caught into this by accident in the beginning of 2010, what are the key things to know about Mozilla development when coming from another big OSS project,...

Case Study: Switching from Linux to FreeBSD

Paul Chvostek
This talk will outline the strategy used to migrate a small Canadian software company's Linux-based server infrastructure to FreeBSD. Part advocacy-strategy and part best-practices, the hope is that you'll come away with some extra tools to promote implementation of FreeBSD in your workplace. ExperiencePoint is a small (20 person) Canadian company that creates training simulations as web applications. The business is wholly dependent on its web server infrastructure for delivering its product. In 2011, I...
