Мотики 2020 (Николай Тенев)

Четвърто издание на най-интересните бъгове и странни проблеми, с които сме се борили в последните месеци. Можем ли да разчитаме на софтуера и хардуера, който всички ползваме? Как се работи в такива условия?

OpenBSD 6.8 and you (Peter Hansteen)

Every six months for the last 25 years, the OpenBSD project has issued a new release of the security focused, general purpose free operating system. This talk aims to show how OpenBSD is important far beyond its own user population: as a source of innovations in security later adopted elsewhere and as upstream for software and whole subsystems re-used by other projects both free and proprietary. Time allowing some specifics of the most recent releases will be covered in more detail.

“If you can't measure it, you can't manage it” (Ivana Atanasova)

Open Source is already established as a standard for many evolving technologies and there is almost no project that is not based on it or using it in some aspect. This type of software can give maintainers and contributors independence on how they can lead and develop their projects, but more freedom means higher responsibility for the project leadership. One major role of an Open Source Program Office (OSPO) is to assist projects to become sustainable and recognized as reliable for adoption. In this talk, we will share the example criteria that measure a project’s “health” and will discuss how to interpret the data to identify potential problems. The CHAOSS project’s Augur tool has developed over the past years to enable this type of data collection and metrics measurement. We will show examples of projects we are working with and how we assess their health. We believe that such knowledge can benefit the whole ecosystem and provide guidance that is highly useful for all stakeholders.

Automated Firewall Testing (Kristof Provost)

Automatically testing the pf firewall, using network stack virtualisation. For fun and profit, or at least for the sake of fewer bugs.

Scalable and automated configuration management with Ansible (Стоил Стоилов)

Използваме Ansible за да осигуряваме и управляваме конфигурацията на контейнерите в нашия частен облак. И ако в началото смятахме, че автоматизацията ще е лека задача и бързо ще отмени много от работата ни, то днес можем да разкажем какво научихме дотук. Защо за три години, пренаписахме някой play-буци два пъти, как преорганизирахме инвентара и за кои модули не искаме да си спомняме. От добри практики, до нашите собствени грешки и как се поучихме от тях.

The Freedom of Static Typing (Andrew Radev)

I'd like to demonstrate some interesting language features in Rust that make it easier to write code and to express concepts compared to dynamic languages. Features that don't just protect you from shooting your feet, but give you power that's only available within the rules and "limitations" of a statically typed language.

Кога отвореният код се проваля (Божидар Божанов)

Отвореният код е нещо прекрасно. Но в някои аспекти и ситуации той се проваля. Ще разгледаме примери и причини за проблемите с UX и леснота на използване, с предвидимостта, с бизнес моделите, със сигурността и с генерирането на търсене.

Building a modern SaaS in 2020 (Николай Стоицев)

Building a modern Software as a Service platform brings a lot of interesting engineering challenges. During this talk, I’m going to share my team’s journey of building a SaaS from scratch in 2020. First, we are going to start with the technologies and the architecture we picked. Then, we’ll go over the interesting challenge of implementing multitenancy. And we'll see how we benchmarked three different options and picked one. And last but not least, we’ll explore how every startup can use open source technologies to build observability infrastructure. And how to run their SaaS in production.

Професия "Откривател на топла вода" (Krasimir Tsonev)

За всички мисля е ясно, че в нашата професия ниво се вдига чрез правене. Какво и как правите обаче не е без значение. Имам желание да ви разходя из нещата, които правя в свободното си време. Повечето ми проекти моментално влизат в графата "е то това вече го има", но истината е че работата по подобни библиотеки ми носи много ползи. Какви точно, ще разберете ако гледате презентацията.

Миграция към KVM (Венко Моянков)

Ще разкажем за процеса на мигриране на виртуални машини от VMware, Hyper-V и XenServer към KVM с минимално прекъсване и ще покажем демо на живо. В процеса използваме инструменти с отворен код, включително няколко създадени от нас за да сведем времето, за което машината е недостъпна, до няколко секунди.

Kuma - a Service Mesh for the masses (Николай Николаев)

Kuma е имплементация на Service Mesh концепцията за свързаност на приложения в облака. Проектът е разработен от комапнията Kong, известна със своите API-management решения и дарен на Cloud Native Computing Foundation. Някой от най-важните особености на Kuma са възможносста му да свързва услуги работещи в Kubernetes и такива изпълнявани във виртуални машини, като позволява свързването на различни по тип и мног на брой клъстери (т.нар. зони). Лекцията ще представи версия 1.0, която ще бъде официално достъпна за ползване през Ноември 2020.

Open Source and the Enterprise - the Win-Win Game (Velichka Atanasova)

Open source software exists today as the dominant force within the technology industry. It is one of the keys to speeding innovation for large and small businesses. Not only companies use open source in their technology stack, achieving symbiotic existence of their proprietary products and services with the open source components but they build and contribute to open source software projects that are, by definition, free to use, modify and distribute. This talk will reveal the main reasons behind that. The right balance between the open source contributions and the economic self-interest, enables a mutually beneficial relationship between enterprise and open source, with open source supporting enterprise products and enterprise encouraging open source innovation. Join the talk to find out how companies do that. A sneak peek - it has something to do with passionate and talented open source engineers (just like some of you) companies are happy to have in their ranks.
