Synthetic web performance testing with Selenium
Synthetic web performance testing with SeleniumAndriy Samilyak This document discusses using Selenium to perform synthetic performance monitoring of web applications. It proposes running Selenium tests to simulate user workflows and transactions, sending timestamps via UDP to Splunk at each step to combine into transactions. Screenshots and HAR files are captured when tests fail to help debug issues. While this provides monitoring with existing Selenium tests, it requires significant effort to support and doesn't always provide enough debug information.
Performance with Selenium2
Performance with Selenium2Oleksii Zozulenko The document discusses performance testing tools and frameworks, including Selenium. It summarizes a tool called Xceptance LoadTest (XLT) that can be used to perform load and performance testing with Selenium. XLT allows recording and playing back of tests in Firefox, generates reports, and has a flexible configuration. However, the commercial license for XLT is quite expensive for larger load tests. The presenter is a QA team lead providing information on performance testing and XLT to help with performance and load testing using Selenium.

Random. Kinda.awwaiid The document discusses a "Just Another Perl Hacker" (JAPH) obfuscated code challenge that generates random text through a series of seeds and offsets. It then analyzes the Perl code to deobfuscate how it works by seeding a pseudo-random number generator, taking offsets, and gathering random characters to build the output string. Several pseudo-random number generation techniques are also briefly described including the middle square method.

A Partial Multiverse Model of Time Travel for Debugging
A Partial Multiverse Model of Time Travel for Debuggingawwaiid As presented at RubyConf 2014 (San Diego). Lots of live coding, I'll link the video eventually.
ABSTRACT:
Ever type 'next' into your debugger and then realize you should have used 'step'? Or perhaps invoked a method that you wish you could take back? Regret no more! Just turn the clock back a few ticks and begin again! With only a few restrictions and side-effects we will learn how to construct and use a time machine.
WARNING: Time travel may cause zombies.

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency.
This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data.
Attendees will learn:
- Consumer awareness around data brokers and what consumers are doing to limit data collection
- How businesses assess third-party vendors and their consent management operations
- Where business preparedness needs improvement
- What these trends mean for the future of privacy governance and public trust
This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
