It can be difficult for users to understand and modify workflow procedures in their applications. The job lifecycle of workflow-driven applications may change based on some specific procedures. We know that people can memorize images, shapes, and colors more easily than raw data. Using Ext JS Draw package, we created a dynamic, easy to use, workflow diagram modeler. We delivered a distinct solution that overcomes the challenges our users encountered. With our modeler, users can drag and drop, resize, label, and connect workflow steps with minimal effort. This ensures that users can visualize and design workflows in a more natural and innovative way.
Tutorial on the use of Ruby Processing for developing visual graphics and interactive graphics. Includes conceptual and real-world examples, including use for business data mining.
This slide will present about the Android Icon Sizes and the way to use Vector Drawable in the Application. You can find the example of using Vector Drawable by using Victor library from Trello git repository. Please check and enjoy!
This session will cover why Sencha Ext JS 5 was selected to replace the current Silverlight version and why Sencha Ext JS 5 is a great fit for COSMOS.

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).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

3. “Canvas is my favourite part
of HTML5, alongside its
video and audio support”
Myself, at some point
5. An overview of canvas
✽ 2D drawing platform within the browser
✽ Uses nothing more than JavaScript and
HTML – no plugins
✽ Extensible through a JavaScript API
✽ Created by Apple for dashboard widgets
✽ Now openly developed as a W3C spec
6. Bitmap vs. vector
✽ Canvas is a bitmap system
• Everything is drawn as a single, flat, picture
• Changes require the whole picture to be redrawn
✽ SVG is a vector system
• Elements to be drawn are separate DOM objects
• They can be manipulated individually
✽ SVG isn’t part of HTML5
• Future isn’t as rosy as canvas’
7. Browser support
✽ Most modern browsers
• Safari
• Chrome
• Firefox
• Opera
✽ No Internet Explorer support by default
• However, there are hacks to get it working
15. Created using the new HTML5 tag
<canvas height=”600” width=”800”></canvas>
Height and width need to be set explicitly
16. (0,0)
x
y
Uses the standard screen-based
coordinate system
17. Everything is drawn onto the
2D rendering context (ctx)
2D rendering context
Canvas
18. Use getContext() to access the
2D rendering context
var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
This is your friend
19. ctx.fillStyle = 'rgb(255, 0, 0)';
ctx.strokeStyle = 'rgba(0, 255, 0, 0.5)';
Use RGBA for alpha
transparency
fillStyle() and strokeStyle() define
the style of shapes to be drawn
20. Simple shapes
Method Action
fillRect(x, y, w, h) Draws a rectangle using the current fill style
strokeRect(x, y, w, h) Draws the outline of a rectangle using the current
stroke style
clearRect(x, y, w, h) Clears all pixels within the given rectangle
Simple shapes are drawn without
effecting the current path
22. Complex shapes & paths
✽ Paths are a list of subpaths
✽ Subpaths are one or more points
connected by straight or curved lines
✽ Rendering context always has a current
path
✽ A new path should be created for each
individual shape
23. Complex shapes & paths
Method Action
beginPath() Resets the current path
closePath() Closes the current subpath and starts a new one
moveTo(x, y) Creates a new subpath at the given point
fill() Fills the subpaths with the current fill style
stroke() Outlines the subpaths with the current stroke style
24. Complex shapes & paths
Method Action
lineTo(x, y) Draws a straight line from the previous point
rect(x, y, w, h) Adds a new closed rectangular subpath
arc(x, y, radius, startAngle, Adds a subpath along the circumference of
endAngle, anticlockwise) the described circle, within the angles defines
arcTo(x1, y1, x2, y2, radius) Adds a subpath connecting two points by an
arc of the defined radius
bezierCurveTo(cp1x, cp1y, Adds a cubic Bézier curve with the given
cp2x, cp2y, x, y) control points
quadraticCurveTo(cpx, Adds a quadratic Bézier curve with the given
cpy, x, y) control points
34. Harnessing the power
✽ Remember all the shapes on the canvas
✽ Move them, transform them, and make
them interact
✽ Redraw the all the shapes in their new
positions
✽ Rinse and repeat, really quickly
35. My workflow
✽ Treat each shape as a JavaScript object
✽ Each shape object has position values
✽ Store the shape objects in an array
✽ Run a timeout function every 40 ms
✽ Clear the canvas
✽ Make any changes to the shape objects
✽ Loop through and redraw every shape
37. The future of canvas
✽ OOP programming allows much to be
achieved through canvas
✽ It’s flexible and powerful
• Animation engines
• Pseudo 3D graphics
✽ Reading pixel values opens a lot of doors
✽ Integration with other HTML5 elements is
a killer feature
39. Canvas vs. Flash
✽ Canvas will flourish with future
development of frameworks
✽ Its animation capabilities are only just
being realised
✽ Flash has tight integration with the offline
world, but HTML5 is changing that
✽ There is a gap in the market for a GUI for
developing canvas applications
