This document discusses semantic logging using Event Tracing for Windows (ETW) and the Semantic Logging Application Block (SLAB). It describes how ETW allows applications to log events that are observed by consumers, and how SLAB can be used as an ETW consumer to process application events. The document provides examples of using Microsoft EventSource to log to the event log and configure SLAB as both an in-process and out-of-process consumer. It emphasizes treating event methods as a contract and using channels, keywords and opcodes to add meaning to logged events.

Molly Holzschlag - How HTML 5 is Going to Completely Change your Web AppCarsonified Team
The HTML 5 spec was originally called "Web Applications 1.0". Most of the attention has been on the new markup elements, but we'll look further at the applications side of the spec, including: 1. Dynamic images and graphs with canvas 2. Eliminating forms validation with webforms 2.0 3. Local storage for saving your data 4. Geolocation 5. Building toolbars and menus
MVC 6 / ASP.NET 5 represent a fundamental shift for the ASP.NET framework. More than simply the next version, this is a complete rewrite and a break from the old System.Web that was central to all previous versions of ASP.NET. The result is a lighter-weight framework that supports cross platform development and deployment. In this session we explore some of the new building blocks in MVC 6 including Tag Helpers and View Components.

What is going on? Application Diagnostics on Azure - Copenhagen .NET User GroupMaarten Balliauw
We all like building and deploying cloud applications. But what happens once that’s done? How do we know if our application behaves like we expect it to behave? Of course, logging! But how do we get that data off of our machines? How do we sift through a bunch of seemingly meaningless diagnostics? In this session, we’ll look at how we can keep track of our Azure application using structured logging, AppInsights and AppInsights analytics to make all that data more meaningful.

Stating the obvious: adding performance and scalability tests to a Continuous Integration pipeline
Performance and scalability are core quality attributes of any system; unit testing, integration testing, UI testing, they all focus on functional requirements. Good performances mean happy users, less resource usage which translates to lower running costs (power, cloud bills) and customer retention.
In this session we will recall some basic concept of performance testing and demonstrate some of the many tools available in the cloud.
Agile Testing Days 2017 Introducing AgileBI SustainablyRaphael Branger
"We now do Agile BI too” is often heard in todays BI community. But can you really "create" agile in Business Intelligence projects? This presentation shows that Agile BI doesn't necessarily start with the introduction of an iterative project approach. An organisation is well advised to establish first the necessary foundations in regards to organisation, business and technology in order to become capable of an iterative, incremental project approach in the BI domain. In this session you learn which building blocks you need to consider. In addition you will see what a meaningful sequence to these building blocks is. Selected aspects like test automation, BI specific design patterns as well as the Disciplined Agile Framework will be explained in more and practical details.

Delivering High Quality Software Through AgileJohn Bristowe
Delivering high quality software is a risky undertaking. Development and Quality Assurance Managers are in a tight partnership over the war against software bugs. Software quality issues not only delay the time to market for a solution while increasing costs, but they also delay the subsequent benefits to the business. In a business world of increasing focus on compliance and control, Development and QA Managers must balance the need for agility against the reality of quality control. High quality software is the outcome of applying the combination of sound methodologies, best practices and supportive tooling.
This session will outline how to deliver high quality software through Agile and will demonstrate how to apply its practices to your projects and having them supported through tools like Visual Studio and Team Foundation Server.
Modern software systems now increasingly span cloud and on-premises deployments and remote embedded devices and sensors. These distributed systems bring challenges with data, connectivity, performance, and systems management; to ensure success, you must design and build with operability as a first-class property.
Matthew Skelton shares five practical, tried-and-tested techniques for improving operability with many kinds of software systems, including the cloud, serverless, on-premises, and the IoT: logging as a live diagnostics vector with sparse event IDs; operational checklists and runbook dialog sheets as a discovery mechanism for teams; endpoint health checks as a way to assess runtime dependencies and complexity; correlation IDs beyond simple HTTP calls; and lightweight user personas as drivers for operational dashboards.
These techniques work very differently with different technologies. For instance, an IoT device has limited storage, processing, and I/O, so generating and shipping of logs and metrics looks very different from cloud or serverless cases. However, the principles—logging as a live diagnostics vector, event IDs for discovery, etc.—work remarkably well across very different technologies.
Drawing from his experience helping teams improve the operability of their software systems, Matthew explains what works (and what doesn’t) and how teams can expand their understanding and awareness of operability through these straightforward, team-friendly techniques.

Continuous Profiling in Production: What, Why and HowSadiq Jaffer
Everyone wants to understand what their application is really doing in production, but this information is normally invisible to developers. Profilers tell you what code your application is running but few developers profile and mostly on their development environments. Thankfully production profiling is now a practical reality that can help you solve and avoid performance problems.
Profiling in development can be problematic because it’s rare that you have a realistic workload or performance test for your system. Even if you’ve got accurate performance tests maintaining these and validating that they represent production systems is hugely time consuming and hard. Not only that but often the hardware and operating system that you run in production are different from your development environment.
This pragmatic talk will help you understand the ins and outs of profiling in a production system. You’ll learn about different techniques and approaches that help you understand what’s really happening with your system. This helps you to solve new performance problems, regressions and undertake capacity planning exercises.
Find out how profiling in production can uncover performance bottlenecks, aid scalability and reduce your costs.
In this talk, Matthew Skelton (Skelton Thatcher Consulting) explores five practical, tried-and-tested, real-world techniques for improving operability with many kinds of software systems, including cloud, Serverless, on-premise, and IoT.
Logging as a live diagnostics vector with sparse event IDs
Operational checklists and 'run book dialogue sheets' as a discovery mechanism for teams
Endpoint healthchecks as a way to assess runtime dependencies and complexity
Correlation IDs beyond simple HTTP calls
Lightweight 'User Personas' as drivers for operational dashboards
These techniques work very differently with different technologies. For instance, an IoT device has limited storage, processing, and I/O, so generation and shipping of logs and metrics looks very different from the cloud or 'serverless' case. However, the principles - logging as a live diagnostics vector, event IDs for discovery, etc - work remarkably well across very different technologies.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Builder.ai Founder Sachin Dev Duggal's Strategic Approach to Create an Innova...Ramesh Iyer
In today's fast-changing business world, Companies that adapt and embrace new ideas often need help to keep up with the competition. However, fostering a culture of innovation takes much work. It takes vision, leadership and willingness to take risks in the right proportion. Sachin Dev Duggal, co-founder of Builder.ai, has perfected the art of this balance, creating a company culture where creativity and growth are nurtured at each stage.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
