Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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!

19. Laser keyboard
(virtual keyboard)
• A Virtual Keyboard is a projection keyboard that is
projected and touched on any surface
• User operates by typing on or within a wireless or optical
-detectable surface or area rather than by depressing
physical keys.
• Proved nightmare for users
• Way to eliminate finger cramping
19
20. What Actually it is:-
• Keyboard that a user operates by typing (moving fingers)
on or within a wireless or optical-detectable surface or
area rather than by depressing physical keys.
20
21. Technologies used:-
• In one technology, the keyboard is projected optically on
a flat surface and, as the user touches the image of a
key, the optical device detects the stroke and sends it to
the computer.
• In another technology, the keyboard is projected on an
area and selected keys are transmitted as wireless
signals using the short-range Bluetooth technology.
• With either approach, a virtual keyboard makes it possible for
the user of a very small smart phone or a wearable computer
to have full keyboard capability.
• Theoretically, with either approach, the keyboard can be in
space and the user can type by moving fingers through the air! 21
22. Reasons to use the virtual
keyboard.
• When connected to your handheld computer it is more
convenient to carry around than your laptop.
• It takes up less desk space than a conventional keyboard.
• You could use it with your desktop, laptop or handheld
computer.
22
23. Advantages:-
• Portability
• Accuracy
• Speed of text entry
• Lack of need for flat or large typing surface
• Ability to minimize the risk for repetitive strain injuries
• Flexibility
• Keyboard layouts can be changed by software allowing for foreign
or Alternative keyboard layouts.
23
24. If there is no wall?
• When we are working in an open place we can make use of a
paper sheet as a screen.
• paper sheet holder is placed at the back panel of this
computer.
• The holder can be opened by pressing it in the lower part
24
27. The software interface
