OSDC 2016 - Interesting things you can do with ZFS by Allan Jude&Benedict Reu...NETWAYS
ZFS is the next generation filesystem originally developed at Sun Microsystems. Available under the CDDL, it uniquely combines volume manager and filesystem into a powerful storage management solution for Unix systems. Regardless of big or small storage requirements. ZFS offers features, for free, that are usually found only in costly enterprise storage solutions. This talk will introduce ZFS and give an overview of its features like snapshots and rollback, compression, deduplication as well as replication. We will demonstrate how these features can make a difference in the datacenter, giving administrators the power and flexibility to adapt to changing storage requirements.
Real world examples of ZFS being used in production for video streaming, virtualization, archival, and research are shown to illustrate the concepts. The talk is intended for people considering ZFS for their data storage needs and those who are interested in the features ZFS provides.
A Journey to Boot Linux on Raspberry PiJian-Hong Pan
Each processor/chip architecture has its own procedure to boot the kernel. It works with desgined partition layout and vendor specific firmwares/bootloaders in the boot partition. We can learn the related knowledge from the Raspbian image for Raspberry Pi, which is the board we can obtain easily. However, the diversity between the special booting procedures with specific firmwares/bootloaders increases the complexity for distribution maintainers. It will be great if there is a way to make it more generic that can be applied to most of the chip architectures/boards to boot up the system.
After referring to some Linux distributions, we learned U-Boot may play a role in the solution. It splits the booting procedure into hardware specific and generic system parts. This helps distribution maintainers deploy the generic system with OSTree, including device trees.
Let’s deep dive into this magic booting procedure!
Upgrade-UX is an open source framework developed to assist in patching and/or updating Unix Operating Systems in a consistent and repeatable way. Especially in the industry it is forbidden just to run yum update (on Linux) to update your Linux system, therefore, upgrade-ux may proof to be a handy tool to guide you through the patching and/or update process as it follows a track you control (evidence gathering, pre/post executing of scripts, logging, and so on).
Snapshots, Replication, and Boot-Environments by Kris Moore eurobsdcon
Abstract
In early 2013 the PC-BSD project decided to re-focus and fully embrace ZFS as its default and only file-system for both desktop and server deployments. This decision immediately spawned development of a new class of tools and utilities which assist users in unlocking the vast potential that ZFS brings to their system. In this talk we will take a look at ZFS Boot-Environments and the new Life-Preserver utility which assists users in ZFS management, including snapshots, replication, mirroring, bare-metal restores and more.

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.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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.
