Open Source as a Business: Strategy, Struggle & Success (Emanuil Tolev)

How do you build a lasting and successful company that also stays true to its open source roots? This talk takes a look at why open source is important to business and three essential elements of this path. We'll look at Elastic, the company behind Elasticsearch, Kibana, Beats, and Logstash, which makes its money with support, the commercial extensions, and cloud offerings.

The Army that Never Existed: The Failure of Social Bots Research (Michael Kreil)

After the shockwaves triggered by the Brexit referendum and the election of Donald Trump, media outlets desperately looked for explanations. Previously unknown researchers offered a saving straw: Automated accounts on social media had influenced the public opinion on a massive scale. This theory was widely spread by research institutions, the media, and even government officials, but taking a closer look at the research behind it shows that the whole social bots theory has absolutely no basis. This fact could have been noticed earlier if the scientists had published their data and their code as it should be standard in science. This talk explains what happened, how it happened, and how it could have been prevented.

A brief history of Web APIs: From CGI to GraphQL (Стефан Добрев)

In this talk, we will follow the evolution of Web APIs from the early '90s through modern days. We will see why some technologies stand the test of time and why others are happily forgotten. Feeling RESTful, wanting more SOAP opera, that's your talk.

Сглобяване на Тинузавър (Neven Boyanov)

Да си сглобим заедно, с поялник, платка Тинузавър с микроконтролер ATtiny85, която после може да програмирате или с Arduino IDE, или с BLOCKTINU средата, разработена специално за Тинузавър.

CryptoParty (Marie Gutbub)

CryptoParty is a decentralized movement with events happening all over the world. The goal is to pass on knowledge about protecting yourself in the digital space. This can include encrypted communication, preventing being tracked while browsing the web and general security advice for computers and smartphones. To try the programs and apps at the CryptoParty bring your laptop or smartphone.

Don't think outside the box, think what can you do with it !

Често сте чували фразата "мисли извън кутията (think outside the box)", но едва ли толкова често някой ви е карал да помислите какво можете да спретнете с една празна кутия? Е, тук създателката на Amalgama.bg ви предизвиква да развихрите своето въображение и да се включите в творческата работилница за рециклирани кутии. Там ще научите нови творчески умения, какво означава благозвучната и недотам българска дума "up-cycling", а и ще си тръгнете с готова кутия! :)

OpenSource Gaming (Marian Marinov)

We will simply play the most popular Open Source Games - Xonotic - 0 A.D - OpenRA - Dune 2000 - The Battle for Wesnoth You would need a laptop :)

Open Source at Uber (Marin Dimitrov)

Uber began its open source journey in 2015 when three passionate engineers decided to contribute Uber’s work back to the community. In only four years, Uber’s open source program has fostered 400+ outstanding open source projects with 1,500+ contributors worldwide delivering over 70,000 commits. In 2018, two of Uber’s open source projects, Jaeger and Horovod, were among the winners of InfoWorld’s Best of Open Source Software Awards. In this talk, Brian Hsieh & Marin Dimitrov will share more details on Uber’s open source journey, program and best practices, and how Uber enables open innovation by fostering a healthy and collaborative open source culture.

Anatomy of Cloud Native eBPF Instrumentation (Leonardo Di Donato)

In this talk, the audience will take a deep dive into understanding eBPF in the Linux kernel. The audience will learn how eBPF is used in the Falco’s custom kernel instrumentation for Kubernetes. They will also see how eBPF has enabled us to rewrite the Falco core engine data collection infrastructure using a set of eBPF programs. This talk shows you how you can use eBPF for your use case. Join us as we live to code a simple eBPF program that will pull all kernel syscall information in the same way that Falco does. We create a lightweight “strace-like” program using eBPF. The audience walks away understanding how easy it is to implement an eBPF program for an arbitrary use case.

Как да се представим добре на ИТ интервю (Тони Герджиков)

В следващата лекция ще ви запознаем с някои тънкости в подготовката и реализацията на IT интервю процеса, които ще ви помогнат да се справите по-добре и да си намерите мечтаната работа или позиция.

Arguing with Linus Torvalds (Steven Rostedt)

The Linux kernel is the lowest layer of software (above BIOS) and that requires it to be as efficient as possible. Recent hardware issues have arisen (Spectre and Meltdown) that caused the Linux kernel to have to take measures to protect itself, but these measures have also had a significant impact on performance. One solution was the addition of retpolines, but these slow down indirect calls, which is highly used by trace events. Work has been started to create dynamic call sites in the kernel to handle these cases. But to make these modifications, breakpoints must be used, and emulating calls from breakpoints has various issues. This talk will describe retpolines, why dynamic call sites help and explain the issues as well as various solutions (spoiler, they all suck) to emulating calls with breakpoints. The same issue has recently come up with handling function tracing and live kernel patching, and those will also be explained. Come to this talk to get a good idea of why most kernel developers have gray hair.

Securing BGP beyond the AS origin validation (Атанас Янков)

От самото начало на Internet проблемът със сигурността на BGP рутинг протокола е сериозен и до скоро, въпреки множеството идеи, нямаше налични решения, които да ни предпазят от възможността някой да ни "гепи" мрежите .

Open Source Meets Marketing (Ruth Cheesley)

In a world where a positive digital experience can mean the difference between winning and losing a customer, cross-channel personalisation and a deep understanding of the customer journey is key.

Ansible 101 (John Hawley)

This is a tutorial intended to walk folks through the very basics of Ansible, getting it set up, up and running, passing data, fetching information and generally getting comfortable with the basics of what configuration management is, and specifically Ansible. This is a hands-on tutorial with specific walkthroughs by using virtual machines provided for the tutorial (a laptop sufficiently capable of running two virtual machines would be required).

The leak of billions of passwords (Kirils Solovjovs)

Beginning of 2019 marked the time of many underground user:password databases leaking into the general internet. What's inside those leaks? Who's at risk? How did that happen? And what do we do now?

The Beginner’s Guide to Quantum Computing (Ivan Angelov)

Quantum computers promise to be able to solve problems that will remain forever beyond the capabilities of the classical ones. The solutions to such problems would have far-reaching applications in cryptography, machine learning, as well as a variety of natural sciences. Now, with small-scale, noisy quantum computers emerging out of the research labs, some of them even being available in the cloud for anyone to play around with, quantum computing is attracting a lot of attention. However, the properties that enable the promising potential of quantum computing are the very same ones that both make it extremely difficult to construct quantum computers and defy our classical intuitions. In this talk, I will introduce some of the key elements of quantum computing, such as qubits, quantum gates, and entanglement, and will explain how these enable its promising applications. What does all of this have to do with OSS? Come to the talk to find out!

Business Source Licensing (Асен Тотин)

The world of open source presents a substantial challenge to creating a sustainable business model. MariaDB recently created the Business Source License (BSL) as an alternative to existing approaches. We believe BSL offers the community more benefits that traditional "open core", "dual licensing" and related models, ultimately staying true to the open source spirit.

Software Resiliency in the Cloud (Ivo Vachkov)

This presentation will demonstrate a variety of principles for building Cloud-native applications and how those principles deliver software resiliency. Overall software design should follow a new set of principles in environment with inherent instability.

DoS and DDoS mitigations with eBPF, XDP and DPDK (Marian Marinov)

This talk will cover our exploration into mitigating DoS/DDoS type of attacks with eBPF, XDP and DPDK. You will learn what worked and what not for this type of mitigations.

Going Peer-to-Peer with WebRTC (Luca Ongaro)

Did you know that it is possible to create fully encrypted peer-to-peer connections between web browsers? That you can stream audio, video, and even arbitrary data between browsers (almost) without a server in between? Enter WebRTC: open web standards are truly amazing! This talk explains how WebRTC works, why it is relevant in 2019, how to write your own peer-to-peer applications, and how to move even beyond web browsers and into IoT applications.

Evolving big microservice architectures (Николай Стоицев)

Microservices are a well-established architecture applied by many organizations around the world to build scalable and fault-tolerant backend systems. But as these systems grow so does the number of services in them. And this brings many challenges when we want to introduce new functionality. For a simple feature, engineers may need to spend a lot of time designing the end to end flow, changing code in multiple services and setting up complex test scenarios. During this talk, we’ll explore how to evolve a microservice architecture to be easily extensible based on some lessons learned from running 5000 microservices in production. We’ll go over different architectural patterns and open source tools that we can use to make it easy for all engineers to understand, extend and be more and more productive in such big complex systems.

GNU/Linux: coming to a phone near you (Merlijn Wajer)

This talk will present (and show off) the current state of Maemo Leste on a handful of mobile phones and tablets, including but not limited to: PinePhone development kit, PinePhone prototype (if available at the time), PineTab development kit, Nokia N900, Nexus 5 and the Motorola Droid 4. We will show phone calls, data connections, wireless, virtual keyboards and more.

From 0kmph to Blinking LED (John Hawley)

It's hard to argue that we aren't living in a new golden age, one where technology is becoming pervasive in ways that our ancestors could only describe as impossible. We have watches you can not only talk to and make phone calls on, but that tell the time, phones that are used more to browse the web than to talk on, and TVs without channels anymore, but more content to view than could be imagined. As most software folks will attest, making a lot of this work isn't that hard - but as software people we can become divorced from the hardware we work on, and with IoT bringing cheap, plentiful, and VERY powerful computers and microcontrollers, maybe it's time that software developers should also start building their own hardware as well.

Diversity & Inclusion & Why it is so important! (Димитър Йорданов)

At the moment diversity is a hot topic for many companies globally. But why do we need it? To have a diverse team is increasingly being recognized as instrumental for improving the overall performance, driving innovation and is also imperative that organizations can no longer choose to ignore. Diversity is key to our growth as individuals and as organizations. It is widely recognized today that diversity adds a lot of value, even if it requires working through the issues and costs that sometimes comes with it. The purpose of this Workshop is to provide a broad discussion of the concepts of diversity and inclusion in the workplace and provide a better understanding of what they may mean for organizations. This BoF also aims to assist the participants in thinking about both differences and similarities among employees, and how these can be leveraged, and accommodated, by the organization.

Отвъд мигащия светодиод (Dimo Dimov)

След лекцията "Blinking LED remake", този уъркшоп е директен разговор с Вас (на български или англиийски) и практическа демонстрация на софтуер с отворен код, който, според автора, може успешно да замени съответния комерсиален софтуер (с недостъпен изходен код). After the "Blinking LED remake", this workshop is a one-to-one conversation (in English or Bulgarian) and a practical demonstration of FOSS that, according to the author, can successfully replace closed source commercial software.

Best practices in creating build and deployment pipelines (Boyan Mihaylov)

The code that we, developers, write only works when this happens in production. The journey from our development machine to production defines the quality of this code and the flexibility of the entire organization to create value for its end-users. In this talk, we will explore theories and best practices for enabling continuous integration/deployment for your organization. We will see good and bad examples from my experience within different types of organizations and the implication such build/deployment pipelines have on the entire organization.

How to get through the awkwardness of networking (Wesley Faulkner)

There's a lot about modern networking that we all should un-learn. Showing off your knowledge and targeting the "important" connections is the wrong approach. If you genuinely want to be an effective networker, you have to shift away from looking at these interactions as transactional. That said, it's still hard to find people to talk to, and even harder to know to start up a conversation. I'll give you tips that will help you work through those issues and ultimately make you more comfortable in new spaces with new people. You'll come away from this presentation with advice you can put to use immediately.

WiFi-Mesh for monitoring and management of large areas (Цветан Узунов)

По време на лекцията ще се опишат и демонстрират възможностите на WiFi-mesh технологията, с която се покриват големи площи, като е достатъчно точките в мрежата да виждат поне един съседен елемент. Приложенията на тази технология са много - от мониторинг и отдалечено управление на машини в заводи, до охрана, автоматизация и климатизация на големи сгради и обекти, без да се полагат допълнителни кабели. За да работи мрежата е необходимо просто да има захранване, т.е. съществуваща електрическа инсталация.

Free and open source toolchains for FPGAs (Rangel Ivanov)

Днес почти всички компилатори и интерпретатори за софтуер/фърмуер са open source. Ако искате да пробвате някой език или платформа, няма проблем: отивате на сайта на съответния език, сваляте си компилатора/интерпретатора или инсталирате съответния пакет за вашата GNU/Linux дистрибуция и сте готови. Искате да разберете как работи дадена част от компилатора/интерпретатора или искате да поправите някой бъг, няма проблем - почти всички са open source. Но уви, при програмируемия хардуер(FPGA) не е така. В тази лекция ще засегнем какви opensource tools съществуват, кои устройства/чипове поддържат, opensource FPGA дизайни/проекти, ползващи чипове, които се поддържат от opensource инструментите, какви проекти могат да се реализират с тях, какви платки за разработка със съответните чипове съществуват и какво предстои занапред.

Building the next telco: Introduction to Network Service Mesh (Ivana Atanasova)

The technology evolution drives a significant continuous increase in the total number of connected devices and the overall generated traffic. This pushes network service providers, like ISPs and Telcos, to carefully consider their technology choices when designing their next-generation architectures. Unfortunately, the current generation of container networking solutions doesn't fit very well to those preventing industries with more sophisticated network demands from adopting the new cloud-native paradigm. The newly adopted CNCF Sandbox project, Network Service Mesh, offers a potential solution. In this talk we'll introduce the novel approach Network Service Mesh uses to solve complicated L2/L3 challenges in Kubernetes. We will also discuss use-cases and provide a set of examples of this solution.

Job security или как да стана неуволняем (Живко Ангелов)

Лоши практики при писането на код, погледнато от смешната страна.

Testing Cloud Native applications with KIND (Rostislav Georgiev)

This talk will walk you through testing cloud native applications (or parts of them) with KIND. KIND is a relatively new project. Started in 2018 by the Kubernetes community, it allows you to create a test Kubernetes cluster, that is close to production, yet easy to use by test automation and end-users alike.

Pimp your bike – направете велосипеда си с мигачи тип Audi (Цветан Узунов)

Елате и тунинговайте велосипеда си с мигачи тип Audi! Както винаги, китовете и участието в работилницата са безплатни. Броят на поялниците ни е ограничен, така че, ако вече имате свой, идвайте с него, за да стават нещата по-бързо. Тъй като китовете ще бъдат само 100 бр, не е лошо да се регистрирате по-рано на info@olimex.com, за да Ви запазим кит, защото предполагаме, че интересът ще е голям и може да не стигнат за всички желаещи.

Getting Started with Mautic (Ruth Cheesley)

Interested in learning how to get started with the Open Source Mautic Marketing Automation tool? In this workshop, we will revisit the basics of what Marketing Automation is, and will work through setting up Mautic for a fictional company.

Hands On Elasticsearch (Emanuil Tolev)

Методика за добиване на универсални умения за разработка на код (Георги Пенков)

Методика за добиване на универсални умения за разработка на код и работа с инф. системи, формализирана в опита от над 1500 преподавателски часа във ФМИ на СУ и НБУ.

Databases in Kubernetes 101 (Petko Vasilev)

As Kubernetes is getting more and more popular, developers are trying to put their whole stack in it. A vital part of this stack is the database, which is by definition stateful, and as such presents a unique set of problems that need to be addressed in order to achieve a robust system. Here we'll discuss a primary/replica MariaDB Server topology fronted by a MariaDB MaxScale proxy.

Мотики 19.11 (Николай Тенев)

Резюме на най-интересните бъгове и странни проблеми, с които сме се борили в последните месец-два.

Фактори за успеха на ML решенията (Пейо Попов)

За успеха на един ML проект оптимизацията на алгоритмите и използването на последните достижения имат сравнително малък принос. Ефективните усилия са насочени към определяне измерители за успех, всички аспекти на данните, включване на хора в процесите, инфраструктура за автоматизация, интеграция и чак тогава към ML оптимизация. Най-голямо значение имат човешките умения, процеси и инструменти, като "AI магията" единствено ги умножава.

EdgeX Foundry - Microservices at the Edge (Nikolay Stanchev)

Flexibility and interoperability in the field of IoT software is the main goal. The challenges the IoT needs to handle include resource limitations (CPU/RAM/storage/network capacity and availability), implementing security at the edge of the network, work with a diverse set of devices, that use different network protocols, managing the overall generated data traffic, etc. The mix of platforms, “things” - sensors, actuators, applications, intelligence, etc. all connected in a single IoT deployment is extensive and ever-growing. How do you create a software platform that addresses all these problems, allows incorporation of various edge analytics, communicates to a diverse set of cloud and enterprise platforms like Azure, Google, AWS, etc.?

Fork and Knife: Fishy Chips (Tiberiu Turbureanu)

Most users are not aware that the lower levels of the software in their computers have privileged and unmanaged access to the hardware. Experts from the Technoethical Project return to OpenFest for a new hands-on workshop on how to flash completely libre replacements for the computer BIOS, phone OS and router firmware. #Libreboot #Replicant #LibreCMC

Yoga is Open Source (Димитър Йорданов)

The great dynamics in today's IT industry and Open Source, in particular, bring new challenges on the table that expect a new mindset and new expertise. In this Yoga workshop, I would like to introduce the participants to several Yoga techniques that can help us stretch a bit and relax directly in our working place and this way makes us more productive and happy. P.S. No Yoga mats or special outfit will be needed

Burnout – синдром на професионалното изчерпване (Петър Събев)

Какво е професионално изгаряне, "прегаряне", "изпържване", професионално изчерпване или просто бърнаут? Много от най-продуктивните хора поне веднъж са се чувствали професионално изчерпани - ще разгледаме няколко такива случая, историята на бърнаута накратко, какви са фазите и стадиите, как да се "усещаме", когато сме на път да прегорим, и какви начини има да го победим... За купона ще вкарам Metallica, "Тигре, тигре" и "Sound of Silence" в една презентация, без да пея...

Scalable and secure infrastructure with LXD, ZFS and LUKS (Стоил Стоилов)

Скалируема и сигурна инфраструктура, базирана на LXD контейнери, ZFS и LUKS. Защо избрахме един по-различен технологичен стек при изграждането на инфраструктурата за нашия частен облак. За проучванията и решенията, които взехме и използваме вече над 3 години.

C++ as Assembly 2.0 - Hello Nim (Виктор Кирилов)

Nim is statically typed systems and applications programming language which offers some of the most powerful metaprogramming capabilities. It is the next iteration of imperative language design and aims to dethrone C/C++ for high performance coding - among its rivals are Rust and D. Nim is also perfectly suited for software typically written in C#, Java, JavaScript, etc. - basically all types of software. Nim can bridge the gap between business logic and high performance, sprinkling improved developer productivity on top. Nim is compiled to C/C++ (and JavaScript among others) and thus interoperability is straightforward and without any performance penalties - lots of existing C/C++ software can be reused and built upon.

За свободата, програмиста и развитието (Николай Цветинов)

Напоследък от господин програмиста се очаква много! То това важи и за госпожицата/госпожата програмист(ка?)! Много, много, много, толкова много, че само работенето не стига, за да се развиваме в правилните насоки… Какво означава това? Трябва да правим нещо и след работа, че да останем търсени и желани? Всъщност не, има такова предлагане, че и търсенето е голямо, но за да си вършим по-добре работата, можем да поработим над себе си. Работата над себе си е важна работа. Нали все дирят магьосници (бели, сиви, но не и черни) и нинджи (черни!!!!). Аз съм правил различни неща през живота си, за да "вдигам левъл", та реших да споделя, както и да поразсъждавам над тези въпроси. И не, няма да си говорим за хобита като "свирене на гайда", което е яко, ама е офтопик. Ще си говорим за хобита и странични дейности, свързани с компютърни науки, информатика, математика, програмиране. Нека пофилософстваме за книгите, които си струват, конференциите и дали и за какво да говорим на тях, отворения код, затворения код, абе кода въобще, за програмистите и креативността, за свободата и още нещо…

Infrastructrure Review (Владимир Витков)

Who, what, and how makes this event tick and some times tock.

Споделени тренирани модели - следващата стъпка към достъпен AI (Ясен Кипров)

Много често най-добрите невронни мрежи са с много слоеве и параметри и са тренирани върху огромни количества данни дълго време. Ще направим обзор на някои такива мрежи и научните екипи, които споделят вече тренирани модели за мрежите си. Ще обсъдим как можем да адаптираме такива модели за нови задачи.

Платформа за проучвания на градската среда (Йордан Дервишев)

Платформата за проучвания на градската среда има за цел да събира данни за градската среда чрез помощта на гражданите (crowdsourcing). Събраните данни осигуряват актуална информация как хората възприемат средата и ще спомогнат за по-добро ѝ планиране. Платформата е с отворен код и осигурява отворени данни.

About TOOOL Toool is The Open Organisation Of Lockpickers, a growing group of enthusiasts interested in locks, keys, and ways of opening locks without keys. Toool was founded in 2002 in Amsterdam. In 2006, a local chapter in Eindhoven was founded, and in 2015 a chapter started in Groningen. They all have regular meetings (once every other week). Members of Toool are welcome in all cities. People from abroad are welcome too. Especially from Belgium as there is no lockpicking group in Belgium. The USA has a Toool US that was founded in 2005. In the UK, a Toool UK has just been formed in 2014. Both groups are separate legal entities, but they have strong bonds with Toool.NL Find them online: Toool.US Toool.CO.UK
