In this presentation from ISC'14, Christian Kniep from Bull presents: Understand Your Cluster by Overlaying Multiple Information Layers. Kniep is using Docker technology in a novel way to ease the administration of InfiniBand networks.
"Today's data center managers are burdened by a lack of aligned information of multiple layers. Work-flow events like 'job XYZ starts' aligned with performance metrics and events extracted from log facilities are low-hanging fruit that is on the edge to become use-able due to open-source software like Graphite, StatsD, logstash and alike. This talk aims to show off the benefits of merging multiple layers of information within an InfiniBand cluster by using use-cases for system operation and management level personal. Mr. Kniep held two BoF sessions which described the lack of InfiniBand (ISC'12) and generic HPC monitoring (ISC'13). This years' session aims to propose a way to fix it. To drill into the issue, Mr. Kniep uses his recently started project QNIBTerminal to spin up a complete clusterstack using LXC containers."
In order to understand how to scale Node.js you need to know how the internals work together and what type of problems are best suited for it. With the right combination of tools you can easily have a scalable and reliable Node.js cluster.
grifork - fast propagative task runner -IKEDA Kiyoshi
Grifork runs defined tasks on the system in a way like tree's branching.
Give grifork a list of hosts, then it creates a tree graph internally, and runs tasks in a top-down way.
Asynchronous programming is a method of programming that can allow multiple different things to be run concurrently (or in parallel). In Rust, it is accomplished using a high-level idea called a Future.
Asynchronous programming is used a lot for IO because there are many times where you have to wait for something to happen (such as reading from a socket or a file) during which no progress can be made. This is a perfect moment to hand over control to something else so that it can start to make progress. This allows our program to always be making progress, which is the name of the game.
Go through this slides, where Pawan Bisht will be talking about the asynchronous concept in Rust Programming like what operations performed by the Rust compiler that actually makes our code asynchronous and what's the role of waker, poll, etc. With this, you can increase your software/application's performance and responsiveness.

A very quick overview of how Vagrant, Ansible and Docker fits nicely together as a very productive and flexible solution for creating automated development environments.
Building a distributed database is very difficult because we have to make sure that the user data is secure. At PingCAP, we did a lot of testing, including Chaos Engineering, to sure the security of TiDB. In this sharing, we talk about PingCAP's testing philosophy, Chaos practices. We'll also introduce Chaos Mesh, a Chaos Engineering platform based on K8s, and how to use Chaos Mesh to test against your application.

The advent of multicore CPUs have facilitated the enhancement of performance in many application domains. But it has shifted the burden of maximizing the usage of this hardware resource to the developers of operating systems and programming languages and ultimately the software engineers who have to develop the applications.
We first look at the concurrency primitives that modern operating systems provides us to work with, namely processes and threads. With Python, a common approach is to use threads which have shared memory. However this can be difficult to do well as it is easy to run into race conditions and other bugs. And Python threads, unlike OS threads, cannot run at the same time due to the infamous GIL, thus limiting us to only one core.
To utilize multiple cores in Python, an effective and better solution is to use multiple processes, each with their own memory space and provide inter-process communication using message passing. We will look at the multiprocessing module and how to use it for this purpose.

Talk presented by Aarón Fas & Andrés Viedma at the JBcnConf 2015.
'Microservices' is one of the most popular buzzwords in the industry now, but are they really a step forward? Or they might be more a problem than a solution? When are they really helpful? How should they be addressed? What challenges will we face if we decide to implement a microservices based architecture?
One year ago, Tuenti moved from a monolithic PHP backend to a Java + PHP microservices architecture. In this talk, we'll share our experiences so far: how we addressed the change, how we implemented it, why we think it's been valuable for us (and how is that related to the company culture), why it might not be a good idea for your company / application and, mostly, what lessons we have learned from this experience.
asyncio - is young library for asynchronous network programming. Lack of information on proper use and writing code in asyncio as well as production war stories slows down asyncio adoption.
In this talk I'll cover my experience with asyncio in production, best practices for writing reliable and testable asynchronous code as well as bunch of asyncio tips and tricks. We will discuss how run asyncio application in standalone mode, execute blocking code in event loop and moreover how embed asyncio in your synchronous application.
Building Good Containers for Python ApplicationsAll Things Open
Presented by: Moshe Zadka
Presented at the All Things Open 2021
Raleigh, NC, USA
Raleigh Convention Center
Abstract: Building good containers for Python applications means dealing with several niggling pieces. Where do you get your Python? How do you install third-party packages? What kind of pinning should, and shouldn't you do? How do you configure your app?
I will go over all of the answers, indicating trade-offs where necessary and pointing out best practices where a clear answer exists.
Monitoring an infrastructure is still one of the most complex tasks at hand. Yet in this age of Infrastructure as Code a lot of people are still stuck using tools that haven't adapted. This talk will explain you how to look at monitoring your infrastructure from another angle, where you can benefit from using Puppet to deploy and provision your monitoring platforms. This talk will explain you which monitoring tools are suitable for monitoring at scale and Puppet driven provisioning and which ones will only make your life harder than it should be. Where do tools like Icinga, Sensu, Graphite or even CheckMK fit into the picture ?

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

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.

"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.
