description: (September 27, 2010) Professor Leonard Susskind discusses how the forces that act upon strings can affect the quantum mechanics. He also reviews many of the theories of relativity that contributed to string theory today. String theory (with its close relative, M-theory) is the basis for the most ambitious theories of the physical world. It has profoundly influenced our understanding of gravity, cosmology, and particle physics. In this course we will develop the basic theoretical and mathematical ideas, including the string-theoretic origin of gravity, the theory of extra dimensions of space, the connection between strings and black holes, the "landscape" of string theory, and the holographic principle.

description: Energie aus fossilen Energieträgern wie Braunkohle belastet die Atmosphäre mit massiven CO2-Emissionen. Der in der Kohle enthaltene Kohlenstoff stammt aus Pflanzen, die vor Jahrmillionen unter großem Druck und hoher Temperatur tief in der Erde zu Kohle umgewandelt und eingelagert wurden. Heute wachsende Pflanzen hingegen geben bei Verbrennung CO2 ab, das sie der Luft erst vor kurzem entzogen haben, die Bilanz bleibt also ausgeglichen. Diesen Vorteil hat sich das Schweizer Unternehmen AVA-CO2 zunutze gemacht und stellt Kohle aus organischen Reststoffen selbst her – innerhalb weniger Stunden. Dazu hat es eine wirtschaftliche Technologie auf Basis der Hydrothermalen Carbonisierung (HTC) entwickelt. Das Besondere daran ist, dass feuchtes organisches Material ohne eine vorherige Trocknung energiesparend verarbeitet werden kann. Erforscht wurde die HTC ursprünglich von Friedrich Bergius und erstmals im Jahr 1913 beschrieben.

description: The third afternoon panel at 4:AM, Tackling the Challenges of Altmetrics, was chaired by Stacy Konkiel (Altmetric) and was focused on the challenges we see in engaging altmetrics and altmetrics research. - To start, Clément Gévaudan from the Global Development Network (GDN) spoke about research diffusion strategies and practices in developing countries. GDN has started the “Doing Research” pilot program which is a mixed method approach to assessing research systems. They have been using altmetrics can be one of the indicators that can be used to evaluate the efficacy of the information diffusion in the developing world. - Andy Herzog (University of Texas at Arlington) discussed the manual and interactive metric consultation service for faculty that he helped develop and run. Andy and his colleagues would have brief interviews with faculty and get a sense of the metrics that were valuable to them. A customisable report would then be made based on their requirements. These conversations allowed Andy to talk about metrics without talking about metrics. The pilot had very positive responses from faculty and led to data being used in their promotion and tenure dossiers. - Johannes Sorz (University of Vienna) then spoke about the survey undertaken to research faculty at the University of Vienna. The survey covered a range of topics about scholarly life, but also asked specific questions related to web usage and scholarly communications. The results showed that there was interest, but varied by career stage and field. The bias towards early career researchers was apparent in valuing and using online sharing, whereas more senior researchers are more likely to use online academic profiles. - Last up, Jaigris Hodson (Royal Roads University) began with a discussion about the dangers of being a female researcher online. Jaigris’ study looks to research harassment of female academics, the way that manifests, and the particularities of this gendered harassment. With the normalisation of online scholarly communications, many researchers feel pressured to be online. Altmetrics emphasize online contributions, but as a community we need to think about how perilous the online sphere can be for women and members of marginalised communities.

description: - Stephan Buettgen, Plum Analytics – 10 in 10: 10 Altmetrics Use Cases in 10 Minutes: A wide variety of institutions are adopting comprehensive metrics to uncover and tell the stories of their research. These include academic libraries, grant funders, publishers and more. This session will showcase ten different use cases of altmetrics from 10 different users. We will see everything from metrics in an institutional repository to metrics in a grant search system. We will hear stories about how altmetrics helped an early career researcher and more. - Andrew Beeken, University of Lincoln – The University of Lincoln Research Bridge: Measuring the reach and impact of research publications is important in helping UK HEIs respond to challenges in the research landscape. With the modern digital publishing ecosystem, the measurement of emerging alternative metrics is becoming increasingly key, as well as identifying how they can be represented and interpreted across multiple disciplines, sometimes using abstract, synthesized values. This can often be a difficult task to do without specific, specialised tools. To help bring all of these distinct types of measures together, the University of Lincoln is working on a prototype “Research Bridge” platform for use across the institution. This will assist in helping to make sense of not only the currently available metrics, but also institution specific synthesized metrics while being flexible enough to include emerging measures as they become relevant. This presentation will look at the issues surrounding gathering information from disparate systems, the benefits of an open culture and how using altmetrics alongside other available measurements can change the academic perspective on research impact. - Chantelle Rijs, Frontiers – Linking published articles to a research network – a new perspective on the use of altmetrics: We’re accustomed to aggregating and analyzing impact data at an article level. We make correlations between and draw conclusions from the types of impact different article types in different specialties are having across our incredibly diverse scholarly ecosystem. Academic profile information allows for a range of new, enriched associations to be made between the demographic information of the authors and the impact, including altmetrics, of their published work. The Frontiers publishing platform is fully integrated into Loop, the new research network for academics, both of which have integrated Altmetric. These enhanced connections provide a multitude of interesting insights. This presentation will examine the unique linking between published articles, research networks and Altmetric and how the bridging of these gaps highlights new ways to apply altmetrics, including into customized marketing campaigns and article tiering systems at a publishing level and at a research network level: author impact updates and improved content discovery. - Tuija Sonkkila, Aalto University, Leadership Support Services – CRIS and altmetrics: Current Research Information Systems (CRIS) are among the youngest members in the family of support services at academic institutions. However, CRIS systems may be slow in adapting new features. For instance, incorporating various altmetrics could be too much to ask. One obvious answer to this demand is to consider the commercial altmetrics products. Something can be done locally, too. Aalto University CRIS will be launched in 2016. In this talk, I will present some findings on how data from the Pure CRIS system could be used to build a lightweight web application by joining them with data from free altmetrics APIs.

description: Capsicum and Casper are FreeBSD proposal for a clean, robust and intuitive application compartmentalization. Today's sandboxing techniques build on top of existing technologies that weren't really designed for this sort of protection (like chroot(2), rlimit(2), setuid(2), Mandantory Access Control, etc.). Capsicum and Casper provide rich infrastructure for breaking applications into multiple useful sandboxes and thus significantly reducing Trusted Computing Base. Capsicum is a lightweight OS capability and sandbox framework implementing a hybrid capability system model. The Casper daemon enables sandboxed application to use functionality normally unavailable in capability-mode sandboxes. The talk will discuss Capsicum framework, Casper daemon and its services. It will provide introduction based on already implemented examples to those new FreeBSD features. The talk will also present existing portable sandboxing implementations to give clear picture how hacky those solutions are.

description: The The Rapid Open Geospatial User-Driven Enterprise (ROGUE) Joint Capability Technology Demonstration (JCTD) is focused on supporting humanitarian assistance and disaster response efforts in the SOUTHCOM area of responsibility. ROGUE is addressing some of the core challenges in the geospatial community right now -- distributed collaboration, disconnected editing workflows, and provenance of data. All of this is being delivered as open source software, and based on open standards to encourage adoption by partners. This talk will explore how the ROGUE team is using GeoNode, GeoGit, and the OpenGeo Suite to provide a collaborative editing environment that maintains provenance of the data. In addition to developing GeoGit, the ROGUE technical team has demonstrated practical application of the technology through mobile and web applications (Arbiter & MapLoom). Both of these projects are available as open source as well. The discussion will include an overview of how the technology is being used operationally in Honduras and for risk assessment and response. A short demo will wrap up the talk.

description: While FreeBSD has been experiencing a huge momentum with ZFS and UFS2 continues to improve in exciting ways, another UFS variant has seen some advances: Ext2fs is trying to catch up with the new times. FreeBSD's ext2 implementation has a huge history: it started it's life as part of BSD-Lites for CMU's Mach. It got ported to FreeBSD and after some rust gathering it eventually got important merges from NetBSD's port so now it is completely GPL free and is supporting new features. Ext2 uses many concepts that are based on UFS but, for good or for bad, Ext2 has never been considered important enough to compete with the local UFS filesystem in the BSDs. Both filesystems have also taken different design decisions over the years and it is not always clear which developments are a clear win on either side. The core of both filesystems is indeed very similar and that similarity has made it relatively easy to adopt in FreeBSD's Ext2fs many enhancements based on FreeBSD's UFS support. Recent years have seen some developments based on successful Google Summer of Code Projects so FreeBSD's driver has support for the directory index and read-only support for extents. This talk presents the recent developments in ext2fs for FreeBSD and attempts to compare the linux ext2/3/4 features with the typical UFS filesystem in the BSDs.

description: Lumify is an open source big data integration, analytics, and visualization platform designed to help users discover connections and explore relationships in their data. It can ingest anything from spreadsheets and text documents, to images and video, representing this diverse data as a collection of entities, properties, and relationships between entities. Everything is stored in a scalable and secure graph database to enable advanced social network analysis and complex graph traversals. Built on proven open source technologies for big data like Hadoop, Storm, and Accumulo, Lumify supports a variety of mission-critical use cases centered around the emerging concepts of activity-based intelligence (ABI), object-based production (OBP), and human geography (HG). Its intuitive web-based user interface provides a suite of analytic options with multiple views on the data, including 2D and 3D graphs, full-text faceted search, histograms with aggregate statistics, and an interactive geographic map exploration feature. This talk will demonstrate how Lumify can be used to fuse structured and unstructured data from multiple sources into a unified knowledge base, and then analyze that knowledge to uncover hidden connections and actionable insights buried within the data's geospatial context.

GeoMesa: Scalable Geospatial Analytics

uk: Комп'ютерні науки

description: The proliferation of smart phones with embedded geolocation sensors has led to an explosion of geospatial data in all domains. Every mobile app now asks users to enable location services and generates copious geotagged data. Existing solutions for managing this data rely on traditional approaches using geospatial relational RDBMS platforms. GeoMesa is an open source scalable spatio-temporal index built on top of the Accumulo distributed column family database that provides efficient OGC standards based access and query capabilities of very large datasets. GeoMesa provides WMS or WFS services over HTTP for data access as well as an API based on Geotools. Spatial analytics in GeoMesa can leverage Hadoop to perform computations in parallel on a cloud. Sensitive personal information inherent in consumer geolocated data can be protected using Accumulo's cell level security. This talk will cover the indexing structure in GeoMesa and how it enables scalable geospatial analytics in a cloud platform.

Introducing ASLR in FreeBSD

uk: Комп'ютерні науки

description: Address-space layout randomization (ASLR) has existed in many operating systems for a number of years. The most famous implementation is the PaX patch for Linux's kernel. This presentation introduces and announces an ASLR implementation based on PaX for FreeBSD/amd64. Details regarding how ASLR has been ported to FreeBSD and some advanced features will be presented. FreeBSD will soon be getting a port of PaX to 11-CURRENT/amd64. This presentation details changes to how ELF executables are loaded in memory and innovative workarounds for legacy applications that don't support (or misbehave) ASLR. Jails can have their own ASLR settings. Misbehaving applications can be run in a jail with ASLR turned off, while ASLR remains turned on in the other jails and in the host.

description: The growth pace of IPv6 adoption is still slow, but constantly increasing, as more providers and networks migrate. There is one aspect of the adoption that is still underestimated, and it's transition mechanisms, enabling networks speaking different protocols to talk to each other. In may 2013, Switzerland jumped on top of IPv6 utilisation in the world by just having its incumbent operator enable one of these for a large base of its users. This talk will first introduce a handful of different transitioning mechanisms in use, picking the most widely used amongst the plethora of ones available. In the second part, a live demonstration will show the audience how to set up some of them using native tools on OpenBSD and FreeBSD.

description: In this talk I would like to discuss the process I went through in replacing a research file server's OS from Linux to FreeBSD and that of its backup system. Initially, the system was hosting a custom 32bit Gentoo Linux instance and was able to host approximately 2.5TB of data over two file systems backed by a RAID-5 software RAID implementation. The solution I implemented allowed me to leverage all the installed disks as one large ZFSv2 data volume by booting the system as a diskless FreeBSD system. I then utilized istgt (an iSCSI target software package) to offer a large disk to one of the group's 64bit Gentoo Linux compute nodes whereby I could then launch autofs and racoon services. I would like to present this material to the BSDCan attendees to share my experience with others and to show that others can accomplish the same task without spending a large amount of money on proprietary software.

description: An overview of NAND technology, its relevance to FreeBSD, and a discussion of the advantages and disadvantages of the NANDFS and other nand technology in FreeBSD. The first part of this talk will be generally about NAND flash, and is applicable to embedded, PCIe-based flash storage and SSD. The second part of the talk focuses on those technologies in FreeBSD to talk to raw NAND, what can be deployed today, and what additional work will be necessary in the future. NAND Flash technology continues to be important to some market segments in which FreeBSD is deployed. This talk will be in two parts. The first part of the talk will discuss NAND flash generally. The second part of the talk will focus on NAND in a FreeBSD context. In the first part, an overview of AND flash will be presented. Basics about NAND generations, NAND storage strategies (SLC, MLC, TLC), characteristics of NAND, and operational considerations will be discussed. An overview of the trends in NAND evolution and their implications will be presented. The talk will explore how these features apply to SSDs and PCIe cards. This part of the talk will be of interest to anybody using these technologies either directly attached, or in a storage product. The second part of the talk will be more focused on embedding FreeBSD, running FreeBSD from NAND and an exploration of the currently supported technology. Kernel configuration, build parameter and other details necessary to build a system will be presented. Creating a system image is a bigger challenge with NAND flash, because blocks on the part wear out and need to be retired (some blocks come from the factory this way), and how to compensate. The additional features need to be developed to deploy the latest NAND parts may be discussed. The second part of the talk will be more focused more on FreeBSD embedded systems using NAND.

description: Features, like encryption, need to have minimal overhead for them to be widely adopted. If the performance is to slow, few people will use it. The first iteration of AES-XTS using AES-NI in FreeBSD was not much faster than the software version of it. The talk will describe why the AES-XTS algorithm was slow and what was done to improve it. It will cover topics from intrinsics, adding them to gcc and advantages of using them over assembly to how to use HWPC that are included in most modern processors to evaluate performance to identify performance bottle necks. Optimizing code first starts with measuring the performance, but it also requires you to understand the parts of the system so that you can decide if increasing performance is possible. It will cover: 1) Cipher modes and their performance impact 2) Processor performance, understanding pipelining, throughput and latency 3) Other SSE instructions used for XTS tweak factor calculations 4) Intrinsics and their use with GCC and CLANG 5) Using pmcstat and kcachegrind for understand performance. 6) Possible future work to increase the performance beyond what it is today.

Versioning of geospatial data has been an issue for any workflow that involves more than one individual. Questions like who changed what and when become hard to answer, and while versioning approaches have existed for a while, they are cumbersome to use and utilize old paradigms. GeoGit takes concepts and lessons learned from the open source programming world and applies them to management of geospatial information, allowing better and decentralized management of versioned data and enabling new and innovative workflows for collaboration. In this 2 hour workshop, we'll walk through core procedures in managing version history and inter-operating with preexisting spatial software tools.

FreeBSD Test Suite

uk: Комп'ютерні науки

description: FreeBSD has seen the birth of its test suite in 2013 and, while the result is heavily based on experience gained in the NetBSD project, there are significant differences between the two. Come to this talk to learn what the FreeBSD test suite is by looking at the various design choices, the tools in use, the roadmap to the final product and, if you are into coding, some actual examples of tests and the process to plug them into the suite. FreeBSD has been in the need for an automated test suite for a long time. During the last few years, various alternatives have been investigated and, finally, the beginnings of a tangible test suite surfaced in 2013. The FreeBSD test suite is now a reality: the system builds and installs tests out of the box; the test suite can be trivially executed with a single command; the testing cluster is up and running, publishing results for test runs about twice per hour; and there is a lot of ongoing work to make the current setup better. This talk will provide you with a general overview of the new FreeBSD test suite, both from the perspective of an end user and of a developer. We will cover many different areas, including but not limited to: the structure of the test suite, covering the use of Kyua as the run-time engine and the various "frameworks" available to implement test programs; the set up of the continuous testing cluster, to understand how its activity benefits developers; the differences between the FreeBSD and NetBSD test suites, and how the two will eventually converge; the future plans for the test suite, especially in the area of reporting and kernel-level testing; and, to conclude, we will get our hands dirty by seeing actual code for a bunch of simple tests. You will hopefully get a sense of the non-existent difficulty to start writing tests en-masse!

description: The talk covers recent work on providing transparent superpages support for the FreeBSD operating system on ARM. The concept of superpages is a virtual memory system optimization, which allow for efficient use of the TLB translations, effectively reducing the overhead related to the memory management. This technique can significantly increase system's performance at the interface between CPU and main memory thus affecting its overall efficiency. The lecture focuses on presenting superpages mechanism supported by the FreeBSD in the context of its implementation for the ARM architecture. Principles of the virtual memory operations are briefly presented to illustrate the requirements and limitations standing before the related subsystem. The talk provides description of the virtual memory system architecture introduced in ARMv6/v7 compliant processors and the opportunities to take advantage of the superpages technique. The primary focus of the presentation is to elaborate on how the superpages functionality was implemented on FreeBSD/arm and what are the results of its application. The talk presents real-life measurements and benchmarks performed on modern, multiprocessor ARM platforms. Hence, the actual achievements and areas of application are shown. Finally, the article summarizes the integration process to the mainline FreeBSD and discusses the areas of future work and improvements.

Userspace Networking with libuinet

uk: Комп'ютерні науки

description: libuinet is a userspace library version of the FreeBSD TCP/IP stack that also includes extensions to the base stack functionality that make it particularly useful in network infrastructure equipment. This talk will cover its design goals, implementation, current and potential uses, and performance. libuinet was originally conceived as a way to bring highly scalable transparent proxy functionality to the free, portable TCP proxy WANProxy (http://wanproxy.org). To this end, libuinet extends the base FreeBSD TCP/IP stack feature set to include 'promiscuous sockets', which allow listens to capture connection attempts across VLANs (including nested), any IP address, and any port, admit/ignore those attempts based on an application-supplied filter, and retrieve the complete L2 and L3 details of admitted connections. Promiscuous socket functionality also allows active connections to fully specify their L2 and L3 identity. In this mode, libuinet has been shown to scale to 1 million active connections concurrent with 1 million listen sockets, with those million connections distributed in multiple ways across the VLAN and 4-tuple TCP addressing space. Implementation of another extension to the stack, 'passive sockets', is currently underway and targeted for completion by the end of 1Q2014. Passive sockets provide for reassembly of both data streams in a TCP connection, along with a missing-frame notification mechanism, based on a copy of the packet stream flowing between the connection endpoints (e.g., via a SPAN port).
