In recognition of Global Accessibility Awareness Day on May 21, 2015, this presentation for Code for San Francisco introduces an accessibility strategy to involve the entire team, including user experience, in creating an inclusive, improved experience for everyone: - Allow everyone to own accessibility - Empower the team with education - Share a vocabulary - Integrate accessibility into your brand - Institute accessibility into your culture - Build accessibility into your Content Management System (CMS) Well before development, there are many opportunities for other team members to integrate accessibility into product planning, content and design. The presentation also takes a closer look at how the content team can be a greater accessibility ally and resource.

The IAM program needs to align behind the shift towards ITaaS, building the platform for execution and supporting transformation and migration activities. CIOs should keep informed through a relevant IAM capability roadmap in order to make calculated decisions on where investments should be made. Ongoing investments in the IAM program are crucial in order to fill capability gaps, keep up-to-date with support and license agreements and make opportunistic progress on the strategic roadmap. In this talk, Steve discusses recent experiences and lessons learned in preparing for and pitching VMware’s CIO on enterprise IAM program initiatives.

The world is not only getting smaller, it’s getting faster. Today’s CEOs are focused on business agility, innovation and competitive advantage to drive growth and profit. And cloud computing is taking center stage as the disruptive force powering faster, more agile business innovation. But threats to the business are growing, often putting the CSO is the uncomfortable position to say “no," or to — wisely — slow down new initiatives to make sure they are handled carefully. So how does the CSO transform to enabler of business growth and innovation while simultaneously protecting the business? CloudPassage CTO Amrit Williams discusses the case for this transformation, why cloud computing can be your friend, five actionable steps CSOs can adopt to become business enablers, and how the right cloud security platform can help.

Despite being around for well over six years, the position of a "cyber threat analyst" is one that is still not yet clearly defined. The lack of definition is due to the positions popularity and infancy. This talk isn't about stating which definition is right or wrong. This presentation is about the set of skills, concepts and theories which enable an analyst to be successful under any definition of "cyber threat analyst". For beginners it is a road-map. For experienced analysts it is a cross-pollination of ideas. I was extremely excited and nervous to deliver the first non-keynote presentation at bsides NOVA 2017. The actual presentation is posted to youtube: https://www.youtube.com/watch?v=Xzd4ousd8-U&list=PLNhlcxQZJSm95e9Z5mvkAk5H3eEBFuVSf&index=19

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.
