CESNET has been using OpenNebula in academic/research environment since 2011. Over the years, we had to develop a bunch of small(ish) tools and helpers to make our lives easier. This talk will present a carefully selected subset of tools that we found the most useful, educational, or interesting. It will also reminisce about tools that are long gone, no longer necessary thanks to continuing OpenNebula development. YouTube: https://youtu.be/FBmZh92mEq4

OO en C# hebben geen geheimen meer voor jou. Maar toch, af en toe is nog veel code nodig om eenvoudige dingen te doen. Welkom in de wereld van functioneel programmeren. Of je worstelt met state en variabelen die onder je neus wijzigen?! Immutable collections bieden een uitweg. Deze sessie zal diep ingaan op pure functions, persistent collections, memoize, interactive extensions en andere technieken die de ervaren C# ontwikkelaar in zijn gereedschapskist moet hebben.

OpenStack is an IaaS provider software written in Python. As such, it provides a massive scalable operating system and services like: Image, Storage, Object, Compute, etc. This talks aims to give the audience an overview about OpenStack, its capabilities, its modules, coding styles, workflow and organization. As a successful community driven development case, it’s definitely a good reference for anyone willing to take that road or maybe joining existing projects.

Getting started on AWS is easy, but building a scalable, reliable and performant product in the cloud can be a challenge for startups and enterprises alike. Netflix has famously migrated all our services to the cloud. Along the way, we have open sourced large portions of our platform that helped make this a reality. In this talk, Mike McGarr (Manager, Netflix Build Tools) will provide a survey of the @NetflixOSS products available. Mike will also share patterns and lessons Netflix learned migrating to the cloud. Lastly, Mike will leave you with a roadmap for how to get started with @NetflixOSS on your cloud today. This talk will cover the following @NetflixOSS products, and more!

Start guide to web scraping with Scrapy, one of best python modules to do web scraping, with Scrapy everything is more easy. This presentation covers the key concepts of scrapy and the process of criation of spiders. It's the first draft version and will be other versions, until the last version, if you see something that you want to be improved, give feedback and I will take that in consideration. I also talk about some alternatives to scrapy like lxml, newspapers and others. In the final i give you acess to the code used on this presentation, so you cant test easy and fast the concepts talked on this presentation. I hope you like it :D

We've made our way into the world of open cloud — where each organization can find the right cloud for its unique needs. A single cloud management platform cannot be all things to all people. There will be a cloud space with several offerings focused on different environments and/or industries. The OpenNebula commitment to the open cloud is at the very base of its mission — to become the simplest cloud enabling platform — and its purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost-effective, reliable, open enterprise clouds on existing IT infrastructure. The OpenNebula Conference will be a great opportunity to communicate and share our vision and commitment, to look back at how the project has grown in the last 9 years, and to shed some insight into what to expect from the project in the near future.
