Docker orchestration using core os and ansible - Ansible IL 2015Leonid Mirsky
The last couple of years have seen an increasing interest in Docker and related technologies. One of these technologies is CoreOS, a new operating system built from the ground up for running Docker containers at scale.
In this talk we will learn about CoreOS main concepts and tools. We will get our hands dirty as we work together toward a goal of running a CoreOS cluster on AWS (using Ansible) and running docker containers on it.
The talk will conclude with a discussion on the place of Ansible (and configuration management tools in general) in the "next-generation" stack.

Docker is een extreem populair en relatief nieuw open source project waarmee containers gemaakt kunnen worden van (bijna alle) applicaties. Een container gebaseerd op Ubuntu met Glassfish en je favoriete applicatie is een van de vele mogelijkheden. Het grootste voordeel is dat Docker containers draaien op (alle) Linux distributies. Dit betekend dat dezelfde container lokaal gebruikt kan worden voor ontwikkeling en in de cloud gebruikt kan worden voor klanten. Docker wordt al gebruikt door grote bedrijven als Ebay en Spotify en ook Google ondersteund het actief. Deze presentatie zal de voordelen van Docker en de best practices behandelen. Tevens zal ik demonstreren hoe Docker werkt zodat je na deze sessie zelf met Docker aan de slag kan.

OSDC 2014: Nat Morris - Open Network Install EnvironmentNETWAYS
ONIE defines an open source “install environment” that runs on this management subsystem utilizing facilities in a Linux/BusyBox environment. This environment allows end-users and channel partners to install the target network OS as part of data center provisioning, in the fashion that servers are provisioned.
ONIE enables switch hardware suppliers, distributors and resellers to manage their operations based on a small number of hardware SKUs. This in turn creates economies of scale in manufacturing, distribution, stocking, and RMA enabling a thriving ecosystem of both network hardware and operating system alternatives.
Remix of two other open source presentations along with my own content, 40 slides set to play at 20 seconds auto-timed (similar to Pecha-Kucha style timing). This was delivered via Caribbean Tech Dev forum's monthly Google Hangout in November 2015, and video can be viewed at https://www.youtube.com/watch?v=xANrsSin_-0

Handling Kernel Upgrades at Scale - The Dirty Cow StoryDataWorks Summit
Apache Hadoop at Yahoo is a massive platform with 36 different clusters spread across YARN, Apache HBase, and Apache Storm deployments, totaling 60,000 servers made up of 100s of different hardware configurations accumulated over generations, presenting unique operational challenges and a variety of unforeseen corner cases. In this talk, we will share methods, tips and tricks to deal with large scale kernel upgrade on heterogeneous platforms within tight timeframes with 100% uptime and no service or data loss through the Dirty COW use case (privilege escalation vulnerability found in the Linux Kernel in late 2016).
We will dive deep into our three phased approach that led to eventual success of the program - pre work, kernel upgrade itself, and post work / cleanup. We will share the details on automation tools, UIs, and reporting tools developed and used to achieve the stated objectives of 800+ server upgrades per hour, track the upgrade progress, validate and report data blocks, and recover quickly from bad blocks encountered. Throughout the talk, we will highlight the importance of process management, communicating with 100s of custom teams to ensure they are onboard and aware, and successful coordination tactics with SREs and Site Operations. We will also touch upon some of the unique challenges we faced along with way such as BIOS updates necessary on over 20,000 hosts along the way, and explain system rolling upgrade support we added to HBase and Storm for avoiding service disruption to low latency customer during these upgrades.
En esta charla hablaremos de como administrar una infraestructura en un startup, como crearla en la nube o en tu data center, los errores mas comunes, las buenas practicas, como escalarar la infraestructura basado en costo/beneficio y sin tener downtimes, y sobre todo optimizarla acorde al tipo de proyecto.

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.

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).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

CoreOS runs on almost any platform, including Vagrant, Amazon
EC2, QEMU/KVM, VMware and OpenStack and your own hardware.
CoreOS is a minimal operating system that supports popular
container systems out of the box. The operating system is designed
to be operated in clusters.
CoreOS doesn't ship a package manager — any software you would
like to use must run within a container.
8. CoreOS Overview
Features
● Automatic update
● btrfs
● Read only rootfs
● Writable overlay on /etc
● No classic package manager (apt, yum, dnf)
● Rollback
9. CoreOS Overview
Automatic Update
Omaha protocol (check-in/retrieval)
Omaha is the open-source version of Google Update, a program to
install requested software and keep it up to date.
The protocol is a fairly simple — it specifies sending HTTP POSTs
with XML data bodies for various events that happen during the
execution of an update.
