Leaflet.annotate - Semantic markup for geographic web maps in HTML

I investigated the public Schema.org vocabulary, the Dublin Core Metadata Element Set, the HTML living standard and SVG 1.1 to make it easy for map makers and publishers to advance the markup they publish. With an understanding of geographic web maps as documents of composite structure i want to share and discuss a LeafletJS implementation representing this investigation. Building on the descriptive markup and this model of a geographic web map i also want to share the idea of developing a user dialog which could support readers of maps in analyzing WHO contributed WHERE, WHEN - and WHAT is the map about. The Leaflet.annotate API can be seen as an interface proposal for other authoring tools or geographic content management systems and with that I hope to contribute to a discussion around accessible and responsible publishing of geographic maps on the WWW.

Copyright Vs. The Internet

As the crusade against sharing of the entertainment industries goes on, we may be about to lose the most precious tool we ever had for exercising our fundamental freedoms and practicing democracy: the Internet. How the future moves of those desperate, yet powerful industries would radically alter the shape of the Internet? How the ACTA agreement may durably bypass democracy and hurt or freedoms? How to react efficintly as a citizen?

The Art of Disrupting Business

Tatiana Bazzichelli describes the concept of "disruptive business" as an art practice, Her analysis becomes an opportunity to imagine new possible routes of social and political action. Distributed, autonomous and decentralised networking practices of disruption become a means for rethinking oppositional hacktivist and artistic strategies within the framework of art and business.

AppStream & Listaller

AppStream provides a solution for application-centric software management using existing package managers, while Listaller extends the package manager with the ability to install 3rd-party applications in a secure way, without introducing additional UI. This talk explains the basic concepts of both projects and the motivation behind them, as well as the obstacles in cross-distro collaboration which we hit while developing these tools. Software management on Linux is traditionally done using packages, although desktop users are more interested in applications instead and do not care much about how something is packaged. Also, users often want to install software which is not available in the repositories (e.g. unpackaged stuff, as well as new versions of applications), without having to upgrade the whole distribution. AppStream provides a solution for application-centric software management using the existing package-managers, by providing extra metadata for packages. This allows developers to create cross-distro application-centers, like GNOME-Software or Apper. Listaller extends the package manager with the ability to install 3rd-party applications, which are not (yet) in the distribution's repositories. It builds on top of the AppStream specs and focuses on integration, so the installation process is completely transparent for users, and Listaller-installed applications can be managed with existing software-management tools. Because software from 3rd-party sources is a potential security risk, Listaller also tries to give users a hint if they can trust a certain application, and includes sandboxing for these applications. Both projects rely heavily on metadata provided by upstream projects and distributions. This talk will explain the concepts of AppStream and Listaller, which new metadata needs to be added and why as well as how distributions can make a software-center available for their users. If the time allows it, the talk will also highlight the problems we had with the AppStream project in the first place and how we could improve cross-distribution collaboration in general

The "War On Sharing" In The EU

Toolbox And Strategies For Winning The "War On Sharing" In The EU: Decentralized citizen movements helped raise massive awareness on legislative and political processes such as SOPA/PIPA in the US, or ACTA on a global scale. How can citizens face these multiple attacks against our freedom online by proposing an alternative to repressive policies? How can we collectively put an end to the "war on sharing" waged against entertainment industries' best clients, in order to foster a vivid digital culture online while protecting a free, open and neutral Internet, and the lulz?

MapStory: The next plateau

MapStory.org is a community-driven open educational resource that lets people share and peer review observations about how the world evolves over time and space. It's built on an open source geospatial stack (PostGIS, GeoServer, OpenLayers, GeoNode) and aims to empower both authoritative and public participation in data collection, peer review, and storytelling. We want to use this session to debut a "new plateau" for MapStory that includes an updated user interface with new features, namely integration of GeoGit Ôcrowdediting' of data and XYT frames for MapStories (what we call StoryBoxes).

A FOSS4G-Based Geo Connection System for Education and Research

The presentation will examine the selection, installation, and the current and planned use of a CentOSÐbased system running FOSS4G to support student education, research, and projects with state and local organizations. A system was designed to foster collaborative work between an educational institution and the community. Specifically, it is being used to better understand and enhance distribution systems associated with local agriculture producers and consumers. Part of this work is the development of a web-based system to process and serve geospatial information in an effort to improve communication between food producers and consumers, i.e. restaurants, farmers markets, and Community Supported Agriculture (CSA). This presentation will demonstrate how the system was built to:¥ Continue investigation of the general principles and approaches for designing food distribution systems to enhance local food networks¥ Provide access to a web-based system for geospatial computations and data management¥ Serve as a resource for the community to access information in support of the broader goals of the CEDS research center¥ Act as an map server¥ Act as the server supporting deployment of geo-aware mobile phone applications implemented by the department to enhance the learning process on field trips and other field work¥ Collect, process, store, and serve data from environmental sensors to support education in weather, climate, and the environment

Growing Up Software Development

Hacker culture overcomes limitations in computer systems through creativity and tinkering. At the same time, hacker culture has shaped the practice of software development to this day. This is problematic - techniques effective for breaking (into) a computer systems are not necessarily suitable for developing resilient and secure systems. It does not have to be this way: We can approach software development as a methodical, systematic activity rather than tinkering, and teach it accordingly. I'll review my experience teaching these methods for the past 18 years and give some suggestions on what *you* may do.

Abusing Bleeding Edge Web Standards for AppSec Glory

Through cooperation between browser vendors and standards bodies in the recent past, numerous standards have been created to enforce stronger client-side control for web applications. As web appsec practitioners continue to shift from mitigating vulnerabilities to implementing proactive controls, each new standard adds another layer of defense for attack patterns previously accepted as risks. With the most basic controls complete, attention is shifting toward mitigating more complex threats. As a result of the drive to control for these threats client-side, standards such as SubResource Integrity (SRI), Content Security Policy (CSP), and HTTP Public Key Pinning (HPKP) carry larger implementation risks than others such as HTTP Strict Transport Security (HSTS). Builders supporting legacy applications actively make trade-offs between implementing the latest standards versus accepting risks simply because of the increased risks newer web standards pose. In this talk, we'll strictly explore the risks posed by SRI, CSP, and HPKP; demonstrate effective mitigation strategies and compromises which may make these standards more accessible to builders and defenders supporting legacy applications; as well as examine emergent properties of standards such as HPKP to cover previously unforeseen scenarios. As a bonus for the breakers, we'll explore and demonstrate exploitations of the emergent risks in these more volatile standards, to include multiple vulnerabilities uncovered quite literally during our research for this talk (which will hopefully be mitigated by d-day). Bio: Bryant Zadegan is an application security advisor and mentor at Mach37, a security accelerator focused on pouring substantial dollars into new security technologies. When not driving developers to embrace AppSec in continuous integration, Bryant punches holes in Amazon, Google, Reddit, etc. On days when he'd rather not touch computers, he's usually nowhere to be found near DC. Ryan Lester is the CEO and chief software architect for Cyph, a web-based one-click end-to-end-encrypted communications service funded in part by Mach37, Virginia's Center for Innovative Technology, and the Goel Fund. Since departing SpaceX, Ryan has dedicated the better part of a year and a half to the vision of accessible encrypted communication. Unsurprisingly, when he isn't working on building the logic for Cyph, he's usually looking for ways to break it.

6th HLF – Hot Topic: Blockchain and distributed ledgers: Presentations "Applications"

Blockchain and distributed ledgers: Will the reality live up to the hype? Will distributed ledger provide a ‘reset’ button for the internet and other networks? Many of the primary privacy risks prevalent today are due to an increasing centralization of information. A decentralized network is potentially more secure but not without its vulnerabilities. During this session, a panel of experts will illuminate how distributed ledgers work, discuss their potential and explore how the world of finance and other application areas could be reshaped. Cryptocurrencies and their escalating, volatile values have successfully captivated the public. However, the rise to fame has not brought a thorough understanding of the underlying technology along with it and distributed ledgers remain largely misunderstood. A better comprehension of the technology is increasingly vital due to its potential ramifications in finance and regarding privacy. Distributed ledgers could conceivably reshape finance through cryptocurrencies and smart contracts, cure data protection issues with social media and re-decentralize the internet. In short, a chance to hit the ‘reset’ button. Simultaneously, the very aspects that make distributed ledgers so promising are the same that make it vulnerable. Though replicability, immutability and being append-only are enormous strengths, they are equally large burdens when used maliciously. The Hot Topic was coordinated and will be moderated by Eva Wolfangel, European Science Writer of the Year 2018, a science journalist with over 15 years of experience covering a range of scientific issues and technological developments and highlighting their significance for the public. In order to unravel the technology behind distributed ledgers and its potential implications, Wolfangel has enlisted the help of experts with backgrounds ranging from academia to industry. Through discussions and an open debate, the speakers aim to distinguish the implausible from the practical and distill how the distributed ledgers will further influence our lives. Experts: Mihai Alisie is the co-founder of Ethereum blockchain applications and founder of Akasha, a social network based on the Ethereum-Blockchain and the InterPlanetary File System. Demelza Hays is researching the role of cryptocurrency in asset management in the Business Economics program at the University of Liechtenstein. Dexter Hadley’s expertise is in translating big data into precision medicine and digital health at the University of California. His background is in genomics and computational biology and he has training in clinical pathology.
