Wasm has emerged as a secure, portable, lightweight, and high-performance runtime sandbox for cloud-native workloads such as microservices and serverless functions. We will show how familiar container tools can be used to develop and share Wasm applications.
Today, there is a large ecosystem of battle-tested tools to create, manage, and deploy Linux container apps in both dev and prod environments. Developers want to use the same tools to manage their Wasm applications to reduce the learning curve and operational risks. More importantly, using the same tools would allow Wasm containers to run side by side with Linux containers. That enables the architectural flexibility to run some workloads (eg lightweight, stateless, transactional, scalable) in Wasm containers, and other workloads (eg long running, heavyweight) in Linux containers.
In this talk, I will cover how to create, publish, share and deploy real-world Wasm applications using Docker Desktop, Podman, containerd, and various flavors of Kubernetes. The examples will feature mixed container types to showcase how Wasm containers work side by side with existing Linux container apps.

In order to calculate the cost of each dbt build execution through dbt-bigquery, I started reading and modifying the source code of the dbt adapter. As long as you have a basic understanding of Python syntax and some simple trace code techniques, such as using "string" that do not change and the stack trace when exceptions occur, combined with a debugger, you can easily achieve the desired effect.
為了想要透過 dbt-bigquery 計算每一次執行 dbt build 的成本，而開始邊讀邊改 dbt adapter 的原始碼。只要你對 Python 有基本的語法概念，再加上簡易的 trace code 技巧：依賴不變的字串與發生例外時的 stack trace，再配合 debugger 就能簡單地改出想要的效果囉！

In this talk, we will be discussing the importance of securing your Kubernetes cluster and how you can do it using the powerful tool, "m9sweeper." As the adoption of Kubernetes continues to grow, it has become more critical to prioritize the security of your cluster.
"M9sweeper" is an open-source security tool that is designed to detect and identify vulnerabilities and misconfigurations in your Kubernetes deployment. It offers a comprehensive set of checks that cover a broad range of security aspects, including network policies, access control, encryption, and pod security.
It has the potential of centralized monitoring of popular Kubernetes security tools Trivy, Gatekeeper, KubeSec, Kube-Hunter, Kube-bench, and Falco.

As the use of containers and Kubernetes for application deployment becomes more widespread, managing the continuous integration/delivery/deployment process can still be a challenge. Tekton and ArgoCD are two CNCF projects that aim to simplify and automate the CI/CD process for containerized applications. In this talk, I will provide an overview of Tekton and ArgoCD and show how they can be used together to streamline the CI/CD process. I will demo how to deploy new features to a Quarkus (game) application in a streamlined and controlled way (and perhaps the audience will get to even play along? ).
This talk is aimed at developers, DevOps engineers, and other Cloud Native / Kubernetes practitioners who are interested in learning more about truly Cloud Native, Serverless CI/CD and how it can be used to improve the automation of building and deploying applications to Kubernetes.
Takeaways: * Introduction to Tekton and ArgoCD * How to leverage pipelines and GitOps to deploy applications * How to release new features continuously using feature flags

Longhorn is a distributed block storage system that has been purpose-built for Kubernetes, making it an ideal cloud-native solution. As an incubating project of the Cloud Native Computing Foundation (CNCF), its main goal is to provide persistent and highly available storage for stateful workloads. In this presentation, we will be exploring Longhorn's architecture and specifically, the data path. Despite offering a wealth of features, such as snapshots, backups, and recurring jobs, there is still room for improvement in the data plane's performance. To address this, a data engine is integrated with Storage Performance Development Kit (SPDK) in the upcoming release, which improves the I/O data path, resulting in better latency and throughput. Additionally, we will introduce the Userspace Block Device Driver (ublk) as a frontend to enhance performance and reduce latency. This feature is particularly useful for edge devices that use legacy data engines.
Jing-Wei Su is a Staff Software Engineer at SUSE from the end of 2021. He is interested in storage technology. He is currently working on the CNCF Longhorn project.
Unikernels are specialized operating system images that execute a single application. Through extreme specialization they can provide high performance, small memory footprints, fast boot times, and a reduced attack vector.

Django is one of the most popular python frameworks used to create web applications. While a lot of people focus on the Django ORM and the Django templating engine, the Django framework also comes with a neat set of middlewares and plugins that can be used to add security headers to your applications. Security headers are a very important layer of defense for your website to keep your users protected. In this talk, we are going to discuss what the different security headers do, and how can we add them to django.

The need for efficient and scalable data management and messaging protocols in distributed systems and IoT applications has become increasingly important in recent years. Zenoh is a new open-source protocol that addresses these issues by providing a lightweight, efficient, and scalable solution. It takes a data-centric approach to communication, which focuses on the data itself rather than the location or identity of the devices producing or consuming the data.
Moreover, Zenoh is built on Rust, a systems programming language known for its high performance, security, and reliability. Rust's unique features make Zenoh a fast and robust solution for managing and processing data in distributed systems and IoT applications.
In this talk, we will explore the architecture and features of Zenoh and discuss real-world use cases.

The lecture focuses on par-stream, a demonstration of stream-oriented programming. It can build a staged pipeline that scales up to CPU cores, and it leverages async/.await to mix I/O-bound and CPU-bound operations. All of them are written in iterator style, allowing users to build a scalable data processing pipeline without tears. The lecture introduces the building blocks to build the pipeline and explores the design in depth.
