Cowboy rabbit-websocketsWade Mealing

This document describes using Erlang, Cowboy, and GenBunny to build an over-engineered chat server with websockets. Cowboy is a small, fast web server for Erlang that supports websockets. GenBunny is a RabbitMQ client library for publishing and subscribing to messages. The server uses Cowboy to handle websocket connections and GenBunny to publish messages to a RabbitMQ exchange. Clients connect via websockets and receive live messages pushed from the server using GenBunny callbacks.

Blazor - An IntroductionJamieTaylor112

Blazor is a new web framework that allows web applications to be written in C# instead of JavaScript. It uses WebAssembly to run .NET code directly in the browser. Developers write Blazor apps using Razor components with HTML and C# code. At runtime, the Blazor runtime compiles the Razor components to WebAssembly, which generates the app's rendering tree and updates the DOM efficiently as the app runs. Blazor provides a way to build interactive client-side web UI using .NET instead of JavaScript.

Take home your very own free Vagrant CFML Dev Environment - Presented at dev....Gavin Pickin

Vagrant is a great solution for providing all of your devs a standard dev environment, but like all the other great technology out there, you have to learn it, and then implement it. Not anymore, this session will give you a well used, documented Vagrant Setup, with the flexibility to use it for all of your future dev projects too. Learn how this Vagrant Environment is setup, and how to extend it. Kill the learning curve, and spin it up today. This setup is being used by several devs, on several projects, and has simple flexibility built in. Drop your repos in the main folder, follow simple conventions, and add a small amount of configuration and be able to spin up your environment in minutes. This setup can configure a simple welcome page, configure the web server and cfml engine mappings, datasources, web server settings per site, host entries, and much more. As great as this sounds, nothing is ever perfect, learn how some assumptions left me looking silly, and owing another developer a meal, and how I resolved that issue and made this vagrant setup even better.

The Rise of Bots – Talk at GeoBeer #15, March 2017Ralph Straumann

This is a lightning talk about the rise of bots (autonomous computer programs), assistance systems, and conversational user interfaces (CUIs). In it I make the case that a solid taxonomy of bots is needed to further the discussion around bots. I highlight some examples of bots and place them into the taxonomy, and finally propose a gradual differentation within the class of bots that 'emulate humans'. This lightning talk was held during GeoBeer #15 (www.geobeer.ch) on March 23, 2017 at the offices of EBP (www.ebp.ch) in Zurich, Switzerland.

6 things people want from their business leaderWorkInConfidence

Why do people follow leaders – and what do they want from their leaders. Most people want leaders who inspire them and who they believe in – but what does this break down into. The requirements have evolved and continue to do, as the power of coercion has decreased, the extent to which our organisations and leaders and their every action are open to public scrutiny and workforces become more mobile. Here are our suggestions for a contemporary list of requirements.

Staying Afloat with Buoy: A High-Performance HTTP Clientlpgauth

In this world of external services, HTTP is king. Unfortunately, the HTTP spec is broad and not always optimized for performance. Instead of trying to be fully RFC compliant, Buoy implements only a subset of HTTP which can be parsed quickly and efficiently. Furthermore, Buoy is built atop Shackle, a high-performance framework for building network clients. Shackle provides Buoy with a very fast connection pooling and safety mechanism against misbehaving servers. - HTTP protocol overview - Buoy's architecture - Shackle framework - buoy_client module - HTTP parsing - Benchmarks - Best practices / tips / tricks

Deadly crossings to Europe. Refugees crossing Mediterranean Sea (2000-2016)David Bihanic

The world is facing the most significant migratory crisis in its history. Even on this very day, millions of refugees are scrambling to reach the EU after fleeing war-torn countries such as Iraq, Syria and Libya. According to the International Organization for Migration (IOM), around 35,000 of them died or went missing between January 2000 and September 2016. The majority of deaths were due to drowning or exhaustion. In 2015, 1 million of refugees tried to cross the Mediterranean — more than 3,770 were reported to have died. Even more worrying for the future, 2016 could be the deadliest year for refugees. To make everyone clearly aware of this large-scale human tragedy, I’ve designed an interactive map that graphically represents (and locates) the dead and missing refugees who have (in particular) crossed the Mediterranean between 2000 and today (detailed information is available by clicking on each dot). This web map also shows the major routes they have taken, the main international migration hubs, and the most populous refugee camps — the leading host countries for refugees are identified in the background.

Provisioning Windows instances at scale on Azure, AWS and OpenStack - Adrian ...ITCamp

In a cloud based environment, where automation is a primary concern, guest operating systems need to be provisioned at boot time. There are a lot of actions that need to be performed at this stage, ranging from assigning the admin user’s credentials to creating WinRM listeners, storage configurations, RDP settings, guest agent installation, custom data execution and much more. The de-facto standard guest provisioning tools are cloud-init on Linux and cloudbase-init on Windows. I will present how cloudbase-init runs on all the Microsoft supported Windows editions (there are quite a few) and how it supports a plethora of metadata service implementations (EC2, OpenStack, the recently added Azure). Cloudbase-init is being run thousands of times daily all over the world’s public clouds and data centers and it has reached more than 5 million known runs to date. We will also take an in-depth look at the Argus integration testing framework, which automates the integration testing of cloudbase-init on real world platforms, to make sure it meets a very strict set of performance, compatibility and security requirements. At the end I will show you a live demo with a cloudbase-init bootstrapped Windows instance on Azure, and how you can benefit from the provisioning process.

Automating Post Exploitation with PowerShellEnclaveSecurity

As organizations assess the security of their information systems, the need for automation has become more and more apparent. Not only are organizations attempting to automate their assessments, the need is becoming more pressing to perform assessments centrally against large numbers of enterprise systems. Penetration testers can use this automation to make their post-exploitation efforts more thorough, repeatable, and efficient. Defenders need to understand the techniques attackers are using once an initial compromise has occurred so they can build defenses to stop the attacks. Microsoft's PowerShell scripting language has become the defacto standard for many organizations looking to perform this level of distributed automation. In this presentation James Tarala, of Enclave Security, will describe to students the enterprise capabilities PowerShell offers and show practical examples of how PowerShell can be used to perform large scale penetration tests of Microsoft Windows systems.

It provides information on Adopt OpenJDK and OpenJDK, links to their homepage and GitHub, describes their build system, and lists various ways to get involved such as helping with documentation, testing binaries, resolving issues, and donating resources. The presentation encourages participation and thanks contributors to the Adopt OpenJDK and wider Java community.

Java 9 / Jigsaw - AJUG/VJUG sessionMani Sarkar

This document provides an agenda and information for a Java 9/Jigsaw hack day event hosted by the Atlanta Java Users Group. The agenda includes sessions on Java 9 modularization, JLink, migrating non-modular apps to Java 9, and feedback. Presenters will discuss what modularization means in Java 9, including splitting the JDK into named modules that declare dependencies. Attendees will have hands-on exercises and are encouraged to provide live feedback.

Java 9 / Jigsaw - LJC / VJUG session (hackday session)Mani Sarkar

Modularisation in Java 9 splits the Java language and JDK/JRE into modules. This includes modularising the OpenJDK source code and runtime images to improve structure, reduce dependencies, and allow for smaller custom runtimes using jlink. The Java Platform Module System (JSR 376) introduced modules that define dependencies and exported/opened packages, allowing Java code and the JDK to be modularized. Hands-on sessions demonstrated creating modules, using jlink to build custom runtimes, and migrating non-modular code to Java 9.

Essential technical skillsMani Sarkar

The document lists essential technical skills for developers such as programming languages, software engineering, computer architecture, and data structures and algorithms. However, it notes these are not the only essential skills, stating that core skills come from understanding ourselves and human technology, specifically how we function internally, communicate internally and externally, and skills like remembering, intuition, and focus. It concludes the real essential skills are qualities like awareness, coherence, and non-violent communication.

How is Java / JVM built ? Back then and now...Mani Sarkar

As some of you may already know, starting with Java 7, OpenJDK is the Reference Implementation (RI) to Java. This presentation walks you through just about that and throws light into many areas that are not common knowledge about this subject. Having said we must move on with time, we used certain tools and methods to do our work in the past and now with improved technology we adapt with the shiny new tools and blend our work with it.

History of javaMani Sarkar

Once upon a time in the C++ century, the Great King of Sun said people need Duke, The PDA (a medieval version of a tablet). He picked his bravest knights – Naughton, Sheriden and Gosling – and entrusted them a secret mission to travel the universe in search for a perfect language that Duke can use. After three years of a dangerous journey in a world of bits, bytes and memory leakages, on an Asian isle they found it. Java made of Oak has been discovered. When they returned the King was not in power anymore. New world was ruled by a mysterious organisation, World Wide Web. Our brave knights honoured it with the glorious Java. And the world became perfect… Mani and Rafal will take your through an exciting story of great programmers, multi-billion company wars, and - most importantly – language features. The history of Java, from its inception till just about today.

Leaning on the two TsMani Sarkar

Leaning on the two Ts is a talk on improving code quality, personal practise and developing good habits using tools and techniques. Attendees of this talk will learn about my experience when learning to use static analysis tools (i.e. SonarQube) and some of its features. In addition also find out how it can be used to improve your code quality and personal practice. A number of tools will also be mentioned and how to include them in your practise. Powerpoint-like presentation sharing information from a perspective higher than just the use of tools, although no runtime implementation or live coding will be performed. Live examples might be shown depending on time constraints. The presentation is definitely for intermediate and experienced Java developers, but also beginner developers who would like to know more about code quality and tools that can be of help. Also for those already using static analysis or other tools in anger or just casually. Especially those who would like to know how to use tools as a medium to learn from.

Scaling GraphRAG: Efficient Knowledge Retrieval for Enterprise AIdanshalev

If we were building a GenAI stack today, we'd start with one question: Can your retrieval system handle multi-hop logic? Trick question, b/c most can’t. They treat retrieval as nearest-neighbor search. Today, we discussed scaling #GraphRAG at AWS DevOps Day, and the takeaway is clear: VectorRAG is naive, lacks domain awareness, and can’t handle full dataset retrieval. GraphRAG builds a knowledge graph from source documents, allowing for a deeper understanding of the data + higher accuracy.

Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...Ranjan Baisak

As software complexity grows, traditional static analysis tools struggle to detect vulnerabilities with both precision and context—often triggering high false positive rates and developer fatigue. This article explores how Graph Neural Networks (GNNs), when applied to source code representations like Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs), and Data Flow Graphs (DFGs), can revolutionize vulnerability detection. We break down how GNNs model code semantics more effectively than flat token sequences, and how techniques like attention mechanisms, hybrid graph construction, and feedback loops significantly reduce false positives. With insights from real-world datasets and recent research, this guide shows how to build more reliable, proactive, and interpretable vulnerability detection systems using GNNs.
