This talk explores the options when trying to bing up a device using an Android Board Support Package (BSP) or AOSP. In particular the options when you don't want to ship a traditional Android device or you have an existing Embedded Linux code base, but all you have available is Android. Headless can mean both be an Android without Java and a device without a display, both are discussed.

Cross-Platform App Development with Flutter, Xamarin, React NativeKorhan Bircan
Previously, we have seen cross-platform solutions but they either compromised on performance or reaching design expectations. Google, Facebook, and Microsoft have been hard at work and I think they now have solutions that are worth taking another look. I want to explore three such popular frameworks: Flutter, Xamarin, and React Native, explain what they are, how they work, and compare them against each other with a focus on performance. My hope is that after reading this article, you are inspired enough to go check them out and know enough to formulate in your mind which technology could be the right choice for your needs.

The OSS platform on which IntelliJ IDEA is based is used by a number of commercial as well as free IDEs, supporting a large number of programming languages and frameworks. And certainly Google's move to use it for their Android Studio increased its usage noticeably.
So what kind of possibilities does it offer for plugin developers? What are the differences compared to Eclipse or NetBeans? What kind of extensions can be developed, is there tooling support and documentation available to guide me?
After discussing these basic questions, we'll take a look at concrete samples: supporting new programming languages, frameworks, small utilities for daily routine tasks and much more. Maybe by now you already have an idea for your first plugin?
And of course, IntelliJ Platform is open source itself, so we'll take a look how you can contribute to it. Or maybe you even want to start working on your own standalone IDE?
You'll have the chance to take away a number of "Lessons Learned" as well as Best Practices from my own 10+ years of experience developing plugins for IntelliJ IDEA.

Presentation material for Indonesia's Tizen Developer Workshop in developing Tizen Native Application Development. It describes on how to develop native application, beginning from Hello Tizen app.
It also covers the overview of Enlightenment Framework Libraries and how to use it on Tizen. Native application styling using EDJE is also covered in App Layouting section, with brief concept on how to code EDC and load it on the runtime.
Finally it gives brief information how developing natively in Tizen is flexible, where we can also utilizes C++ in conjunction with the provided C libraries. It is possible to use external libraries in Tizen if we find that the preloaded Native API is not enough.
The goal of this presentation is to give overview of native application concept while at the same time giving depth concepts to the developers so they can begin developing native Tizen application without hesitation.

Intro to Ionic for Building Hybrid Mobile ApplicationsSasha dos Santos
Ionic is a free framework that allows users to easily build hybrid mobile applications for iOS and Android using Angular and Cordova. Ionic provides a command line interface, CSS classes, reusable components (directives) and various tools for testing and development. In this session, you'll get a birdseye view of what Ionic has to offer, as well as guidelines for building your first Ionic app, including the use of tools such as Yeoman, Bower and Grunt.
The quest for the perfect cross-platform solution has been like the quest for the Holy Grail. It’s been going on a long time, there are a myriad of perceived benefits, and every time someone claims to have found it, it’s never the right one. Many people ask, “Should I go with a cross-platform solution, or a native solution?” but the reality is the quest is bringing us closer to a solution where there isn’t a meaningful difference.
React Native wasn’t the first to show a solution could be both cross-platform and native, but it has certainly convinced a lot of people. As many of those early converts are discovering the limitations, they are beginning to fall back into either-or thinking. Maybe they just have the wrong assumptions.
Kotlin Multiplatform makes some new assumptions and, although it wasn’t the first to do so, is gaining in popularity very quickly. Is Kotlin Multiplatform the holy grail of cross-platform? Probably not. But it does bring cross-platform and native closer than ever before.

Add the power of the Web to your embedded devices with WPE WebKitIgalia
The Web engine is the most important component of a Web Browser: it makes it possible to fetch and interpret web content, allowing users to interact with it. WebKit, the Open Source Web engine used in Web browsers like Safari, provides an architecture particularly well-designed for embedded platforms, making it popular not just for Apple devices, but for all sorts of Linux-based environments too (e.g. set-top-boxes, smart home appliances..). However, a Web engine is a complex piece of software and often not optimized for low-power computers.
This is where WPE, a Linux-based Open Source “port” of WebKit for embedded devices, comes in. Its low memory footprint and focus on simplicity, flexibility, and performance allows for the kind of customization needed to run on bespoke hardware and integrate with a wide variety of requirements. WPE is also developed upstream as part of the WebKit project and regularly published every 6 months via stable releases, guaranteeing that it’s up-to-date with the latest developments in the WebKit community.
In this talk, we will explore WPE in detail, see how the project has evolved, and look at where it’s heading next, highlighting some of its most popular use cases and some experiments that open up brand-new possibilities for this port of WebKit.

NDC TechTown 2023_ Return Oriented Programming an introduction.pdfPatricia Aas
Return Oriented Programming (ROP) is an exploitation technique that folks have often heard of, but don't know the mechanics of. In this talk you will learn how it works, and we will go through some examples to show how it can be used to execute code in contexts where the stack is not executable.

I can't work like this (KDE Academy Keynote 2021)Patricia Aas
Making software products can be fraught with conflicts, where people in different roles may feel sabotaged by others. In this talk I present a model for thinking about the problems we solve and how we solve them, and using that I hope to convince you that team excellence comes from our differences, rather than in spite of them. Hopefully you'll walk away with a deeper understanding of that colleague that never writes tests, or the one that constantly complains that all you do is "make bugs".
Dependency Management in C++ (NDC TechTown 2021)Patricia Aas
C++ has been slow to settle on standardized tools for building and dependency management. In recent years CMake has emerged as the de facto standard for builds, but dependency management still has no clear winner. In this talk I will look into what dependency management might look like in modern C++ projects and how that relates to security.
Introduction to Memory Exploitation (Meeting C++ 2021)Patricia Aas
Stack based exploitation has gotten all the fame, but many platform and compiler mitigations have made it very hard to exploit stack vulnerabilities. Heap based exploits are still very relevant, and since this is black magic for most developers I will here give an introduction to the field.
We keep on thinking we are living in the future, but native exploitation has a rich history, and many times the vulnerabilities and exploitation techniques are decades old. We'll look at some of these, how they have surfaced in recent years and how prepared we are today, armed with modern tooling, to find and fix "classic" vulnerabilities.

Thoughts On Learning A New Programming LanguagePatricia Aas
How should we teach a new language to folks that already know how to program?
How do we use what we already know to leapfrog the learning process?
Based on my personal experience and snippets of natural language theory, we will try to explore the cheats and pitfalls when learning a new programming language, but also dig into how we can make it easier.
Trying to build an Open Source browser in 2020Patricia Aas
A lot of things have been developed over the last 15 years that should make the process of making a browser easier. In this talk we will explore a bunch of different tools, platforms and libraries that could go into making a browser in 2020.
We will also see a live demo of a simple browser built with these OSS projects. We will also discuss the limitations and future work needed to make this work in practice.

DevSecOps for Developers, How To Start (ETC 2020)Patricia Aas
How can you squeeze Security into DevOps? Security is often an understaffed function, so how can you leverage what you have in DevOps to improve your security posture?
Often the culture clash between Security and Development is even more prominent than between Development and Operations. Understanding the differences in how these functions work, and leveraging their similarities, will reveal processes already in place that can be used to improve security. This fine tuning of tools and processes can give you DevSecOps on a shoestring.
The Anatomy of an Exploit (NDC TechTown 2019)Patricia Aas
Security vulnerabilities and secure coding is often talked about in the abstract by programmers, but rarely understood. In this talk we will walk through simple exploit attempts, and finally a simple stack buffer overflow exploit, how it’s developed and how it’s used.
The goal is to try to get a feeling for the point of view of an "attacker", and to slowly start looking at exploitation as just another programming practice. We will mainly be looking at C and x86_64 assembly, so bring snacks.
Elections: Trust and Critical Infrastructure (NDC TechTown 2019)Patricia Aas
Free and correct elections are the linchpin of democracy. For a government to be formed based the will of the people, the will of the people must be heard. Across the world election systems are being classified as critical infrastructure, and they face the same concerns as all other fundamental systems in society.
We are building our critical infrastructure from hardware and software built by nations and companies we can’t expect to trust. How can this be dealt with in Election Security, and can those lessons be applied to other critical systems society depends on today?

Survival Tips for Women in Tech (JavaZone 2019) Patricia Aas
Being the only woman on your team can be hard. Many times it’s difficult to know what is only your experience and what is common. In this talk we’ll go through 24 tips (and a few bonus tips) based on well over a decade of experience being the only woman in several teams. If you’re a woman hopefully you’ll walk out with some ideas you can put to work right away, if you’re a man hopefully you’ll walk out with a new perspective and start noticing things in your day-to-day that you didn’t notice before.
https://patricia.no/2018/09/06/survival_tips_for_women_in_tech.html
More and more we see technology, both hardware and software, intersect with fundamental issues like privacy, democracy and human rights. The opaqueness of tech makes it a handy instrument of oppression and manipulation. We have taught the population to trust us. We have constructed a world in which they have to exist, with little to no oversight or transparency. We build critical infrastructure on hardware and software that even we cannot audit. How can we wield that responsibility? How do we protect those that speak up? How do we protect the population?
Chromium Sandbox on Linux (NDC Security 2019)Patricia Aas
The Linux Security and Isolation APIs have become the basis of some of the most useful features server-side, providing the isolation required for efficient containers.
However, these APIs also form the basis of the Chromium Sandbox on Linux, and we will study them in that context in this talk.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

32. Composition
Need to get pixels on screen
- Compose just one window
with OpenGL
- Compose multiple windows
using external composer /
Hardware Composer
33. The Hardware Composer
Standardized Android porting
API for rendering to the screen.
Takes a set of surfaces and
composes them to the full frame
for the screen.
35. What is LibHybris?
Dynamically loads and links
bionic libc and bionic linked libs
into a glibc process
Gives access to the bionic libs in
a glibc process
Creator : Carsten Munk
36. Linux kernel (w/Android features: binder, wakelocks, etc.)
Headless Glibc Android using LibHybris

37. A bionic GPU process?
Pipe GPU commands over a
local pipe to a bionic process
that does the composition.

46. Existing Codebase
Porting to Java?
Porting from glibc to Bionic?
Rewrite to Android APIs?
What about other APIs you use?
- Do they exist in Android?
47. 3rd-party dependencies?
Port to Bionic? Really !?
Will upstream accept the port?
Remove deps if possible!
What about alternative deps?
Push towards glibc platform!
48. Bringup & Maintenance
Minimize custom hardware!
Decouple customizations from
upstream BSP/platform
Keep changes out of the BSP
- Above the Android APIs
- Or below user space
(kernel drivers, device tree)
50. Avoid patches when you can!
Minimize changes to the BSP itself
Decouple your changes from the guts of
Android
51. Structure your patches!
Patches across many different repos:
- Common scheme for maintenance
- Enumerate your current patchset
- Integrating new upstream release:
- Remove and Refresh
