Clojure - an introduction (and some CFML)Kai Koenig
This is a talk I gave at CFCAMP 2012 in Munich. It's an introduction to Clojure for CFML developers and how to leverage Clojure from a CFML developer's point of view.
There are various examples and demo code that's not on the slides, contact me if you're interested in it.

Introduction to Erlang/(Elixir) at a Webilea Hands-On SessionAndré Graf
Slides used for introducing and training Erlang/Elixir at the Webilea Hands-On event (http://www.meetup.com/webilea/events/170710572/).
Following topics are more or less covered:
1. very short introduction to the language
2. people try some Erlang over at http://tryerlang.org
3. 'Let it crash'
4. Playing with spawn/link/monitor
5. quick intro to gen_sever and supervisor behaviour
Erlang Developments: The Good, The Bad and The Uglyenriquepazperez
A bunch of personal views about the main characteristics of Erlang, including myths and rumors.
A quick overview about what has lately been improved in the three areas.

Pavel Shirshov - DIStage: purely functional programming without sacrificing modularity with modern dependency injection for Scala
- Modularity and its importance
- DI-like mechanisms and their issues in Scala
- Why people think that "DI doesn't compose with functional programming", and why that's not true
- Designing a staged DI, for wiring at runtime, at compile-time, or mixed
- Staging programs for reliability, power and performance
- The pains of supporting rich Scala types (incl. How to emulate kind-polymorphism in Scala 2)
- Garbage collection in DI for better tests and deployments
Pavel's bio: Language-agnostic software engineer, coding for 18 years,
10 years of hands-on commercial engineering experience.
Led a cluster orchestration team at Yandex, "the Russian Google"; implemented an internal orchestration solution, "ISS" (Scala/Java/C++), managing 50K+ physical hosts across 6 datacenters.
Today, Pavel owns Irish R&D company Septimal Mind.
For frontend devs, I am going to present a programming pattern that makes creating interactive browser based user interfaces much simpler than any existing JavaScript framework. I will show how Elm programming language can force us to follow the right path, which is great for working in teams.
For backend devs, I am going to show why it is not wise to use the same patterns (and languages) for backends and present how Elixir provides different set of abstractions which helps with scaling. I also briefly touch on Phoenix Framework principles which have couple similarities to the Elm way.

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

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.
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.

Generating a custom Ruby SDK for your web service or Rails API using Smithyg2nightmarescribd
Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.
