Docker Workshop
Docker is an open platform for building, shipping and running distributed applications. It allows developers to package applications into containers that have everything needed to run, including libraries and other dependencies, and ship them to any Docker-enabled infrastructure. Containers are more portable and provide better isolation than virtual machines, and allow applications to be deployed with minimal overhead or conflict. Docker uses containers, images and a Dockerfile to deploy and run applications reliably across any infrastructure.
Docker Ecosystem: Part III - Machine
This document discusses Docker Machine, a tool that allows managing Docker hosts on virtual hosts, cloud providers, or bare-metal servers. It provides commands for creating and connecting Docker hosts on platforms like VirtualBox, AWS, and Digital Ocean. The presentation demonstrates creating a Docker host, listing hosts, connecting to a host, deploying a sample application, and viewing running containers. It also covers commands for SSH access, file copying, upgrading hosts, and creating hosts on specific cloud providers.

Docker - Build, Ship, and Run Any App, Anywhere
Docker is an open source platform for building, shipping, and running distributed applications. It allows developers to package applications with all dependencies into standardized units called containers that can run on any infrastructure regardless of whether it is a physical or virtual server. Docker helps ensure that the same environment is used at different machines, provides version control for environments, and makes it easy to distribute and collaborate on environments with a team. Docker also eliminates issues with "works on my machine" by ensuring that the production environment will be exactly the same as the development environment.

Introduction to docker
Docker is an open platform for developing, shipping, and running applications. It aims to solve the problem of maintaining different application versions across multiple platforms and servers. Docker allows applications to be packaged into standardized units called containers that contain all their dependencies so they can run reliably from one computing environment to another. Containers operate much more efficiently at runtime than virtual machines, using less memory and CPU resources. Docker images provide a lightweight template for creating containers which bundle application code and dependencies. This allows applications to be easily deployed and scaled across multiple machines.

Since OpenUI5/SAPUI5 1.120, the framework supports the integration of any Web Components. This makes it possible, for example, to natively embed own Web Components of your design system which are created with Stencil. The integration embeds the Web Components in a way that they can be used naturally in XMLViews, like with standard UI5 controls, and can be bound with data binding. Learn how you can also make use of the Web Components base class in OpenUI5/SAPUI5 to also integrate your Web Components and get inspired by the solution to generate a custom UI5 library providing the Web Components control wrappers for the native ones.

The aviation industry has always been a prime target for cybercriminals due to its critical infrastructure and high stakes. In the first quarter of 2024, the sector faced an alarming surge in cybersecurity threats, revealing its vulnerabilities and the relentless sophistication of cyber attackers.
SOCRadar’s Aviation Industry, Quarterly Incident Report, provides an in-depth analysis of these threats, detected and examined through our extensive monitoring of hacker forums, Telegram channels, and dark web platforms.
UI5con 2024 - Boost Your Development Experience with UI5 Tooling Extensions
The UI5 tooling is the development and build tooling of UI5. It is built in a modular and extensible way so that it can be easily extended by your needs. This session will showcase various tooling extensions which can boost your development experience by far so that you can really work offline, transpile your code in your project to use even newer versions of EcmaScript (than 2022 which is supported right now by the UI5 tooling), consume any npm package of your choice in your project, using different kind of proxies, and even stitching UI5 projects during development together to mimic your target environment.
Need for Speed: Removing speed bumps from your Symfony projects ⚡️
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.

OpenMetadata Community Meeting - 5th June 2024
The OpenMetadata Community Meeting was held on June 5th, 2024. In this meeting, we discussed about the data quality capabilities that are integrated with the Incident Manager, providing a complete solution to handle your data observability needs. Watch the end-to-end demo of the data quality features.
* How to run your own data quality framework
* What is the performance impact of running data quality frameworks
* How to run the test cases in your own ETL pipelines
* How the Incident Manager is integrated
* Get notified with alerts when test cases fail

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

Graspan: A Big Data System for Big Code Analysis
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
- Accepted in ASPLOS ‘17, Xi’an, China.
- Featured in the tutorial, Systemized Program Analyses: A Big Data Perspective on Static Analysis Scalability, ASPLOS ‘17.
- Invited for presentation at SoCal PLS ‘16.

Docker Introduction
- 1. Docker Fun with containers & co Jannis Kirschner
- 3. But Docker on Windows also works with Linux???
- 5. The tiny little problem with VMware….
- 6. The party’s over at dockerhub
- 7. Building your own very super duper cool Docker Container
- 8. Dockerfile FROM <os>:<latest> ; Specifies Base Image MAINTAINER <name> ; Represents Author RUN <command> ; Executes Command During Build COPY <src> <dst> ; Copies Files From Host To Container EXPOSE <port> ; Makes Container Listen On This Port CMD <command> ; Executes Command After Build ENV <variablename> <content>; Sets Environment Variables USER <username> ; Sets Userid/Username
- 9. Whaletastic commands # Get container from dockerhub docker pull <publishername>/<containername> # Build dockerimage from dockerfile in current directory docker build –t <imagename>:<version> . # Run container from dockerimage docker run --name <containername> <imagename>:<version> # Show docker processes docker ps # Stop docker container docker stop <containername> # Remove docker container docker rm <containername> # Attach to docker container docker attach <containername>
- 10. Most Important takeoffs Don’t run as root Containers are volatile One task - one container One foreground proccess per container
