How to rewrite the OS using C by strong type
How to rewrite the OS using C by strong typeKiwamu Okabe This document outlines a plan to rewrite an operating system kernel using the C programming language with strong typing. It discusses problems that arise from using C like buffer overruns and page faults in the kernel. It proposes using techniques like algebraic data types and type classes to add flexibility without weak types. It presents existing strongly typed OSes and why they have not seen widespread use. It proposes a "Snatch-driven" approach to incrementally rewrite the kernel in C with strong typing. Finally, it outlines future work areas and alternative languages to consider.

Rust's Journey to Async/await
Rust's Journey to Async/awaitC4Media Rust's Journey to Async/Await
- Rust was initially built for synchronous I/O but the community wanted asynchronous capabilities for building network services.
- This led to the development of futures in Rust to support asynchronous programming. However, futures had design issues that motivated futures 2.0.
- Async/await was developed to make asynchronous code look synchronous while teaching the borrow checker about asynchronous constraints. This involved debate around syntax.
- After years of work, async/await landed in Rust 1.38, completing Rust's journey to fully supporting asynchronous programming. The implementation involved resolving language-specific challenges.
Fun With Reactive Extensions
Fun With Reactive ExtensionsPeter Bons The document discusses the advantages of using Reactive Programming (Rx) over traditional event-based programming. Specifically:
- Events have awkward syntax for registering callbacks and are difficult to compose.
- Rx allows events to be queried over time and provides help for concurrency and multithreading.
- Several examples are given of how Rx can be used to handle notifications, buffer log entries over time, and compose file system events that occur within time periods.
- The document encourages learning more about Rx through online resources and sample code.

Are you using an opensource library? There's a good chance you are vulnerable...Codemotion #Codemotion Rome 2018 - Do you remember Equifax? How did someone manage to steal the data of almost 200 million users? Well, Equifax simply fell victim to a vulnerability on a framework, Struts, which older developers like me remember well. But you folks, who now use cooler things like Guava or Jackson, do you feel safe? Unfortunately, you are not. After a clear introduction to the problem, with a couple of other illustrious examples, we will perform a couple of exploits together, live, and then take a look at possible prevention strategies. This talk will open your eyes to a problem you did not know you had.

Hacklu2011 tricaudstricaud This document discusses how visualization can help make IT security possible when dealing with large scale infrastructure. It describes some common security tools like antivirus software, firewalls, and intrusion detection systems that are used but have limitations. The document then introduces parallel coordinate visualization as a tool that can help analyze large volumes of log and event data to help detect unknown attacks and behaviors. It provides examples of how parallel coordinates could be used to visualize and analyze squid proxy logs, Apache logs, and OpenVPN tunnels. The conclusion is that traditional visualization often fails at scale but parallel coordinates enables analyzing large datasets to find the unknown and understand logs better.

Porting your favourite cmdline tool to Android
Porting your favourite cmdline tool to AndroidVlatko Kosturjak Porting a command line tool to Android involves cross-compiling the code using the Android NDK toolchain, which may require patching the code to address issues like different file paths, endianness, and library dependencies. While compiling and running static binaries is straightforward, dynamic binaries require position-independent executable (PIE) support added in Android 5. Calling native executables from Android code requires using Runtime.exec() or ProcessBuilder and parsing output streams. Special care needs to be taken to avoid security issues like command injection when passing untrusted inputs to native programs run as root on Android.

Server side game_development
Server side game_developmentYekmer Simsek Game development is challenging due to many front-end platforms and issues with sessions not scaling. Long polling and socket programming are alternatives to sessions, but require protocol and database considerations. Open-source alternatives like Reddwarf Server exist, but writing your own server is not recommended. SmartFox Server provides listener-based APIs and client libraries but does not scale and is expensive. Social game companies like Zynga and King use various stacks including Rails, Redis, Erlang and AWS. NoSQL databases like Redis and Riak can be better alternatives than relational databases for games.
OWASP Poland Day 2018 - Andrzej Dyjak - Zero Trust Theorem
OWASP Poland Day 2018 - Andrzej Dyjak - Zero Trust TheoremOWASP This document discusses various security vulnerabilities and solutions across different levels, from web applications and external components to operating systems, hardware, and compilers. Examples are given of vulnerabilities such as XSS, OS command injection, Rowhammer, Meltdown/Spectre, and compiler bugs. Solutions discussed include using secure frameworks, following best practices like least privilege and patching, monitoring system integrity, and fuzzing to discover issues. The overall message is that while best practices reduce risk, both software and hardware are inherently vulnerable, so security must be an ongoing process rather than a single solution.
Everything-as-code - A polyglot adventure
Everything-as-code - A polyglot adventureQAware GmbH Devoxx 2017, Poland: Talk by Mario-Leander Reimer (@LeanderReimer, Principal Software Architect at QAware).
Abstract: As modern, agile architects and developers we need to master several different languages and technologies all at once to build state-of-the-art solutions and yet be 100% productive. We define our development environments using Gradle. We implement our software in Java, Kotlin or another JVM based language. We use Groovy or Scala to test our code at different layers. We construct the build pipelines for our software using a Groovy DSL or JSON. We use YAML and Python to describe the infrastructure and the deployment for our applications. We document our architectures using AsciiDoc and JRuby. Welcome to Babel!
Making the right choices in the multitude of available languages and technologies is not easy. Randomly combining every hip technology out there will surely lead into chaos. What we need is a customized, streamlined tool chain and technology stack that fits the project, your team and the customer’s ecosystem all at once. This code intense, polyglot session is an opinionated journey into the modern era of software industrialization.

Practical IoT Exploitation (DEFCON23 IoTVillage) - Lyon Yang
Practical IoT Exploitation (DEFCON23 IoTVillage) - Lyon YangLyon Yang This is a light training/presentation talk.
My name is Lyon Yang and I am an IoT hacker. I live in sunny Singapore where IoT is rapidly being deployed – in production. This walkthrough will aim to shed light on the subject of IoT, from finding vulnerabilities in IoT devices to getting shiny hash prompts.
Our journey starts with a holistic view of IoT security, the issues faced by IoT devices and the common mistakes made by IoT developers. Things will then get technical as we progress into a both ARM and MIPS exploitation, followed by a ‘hack-along-with-us’ workshop where you will be exploiting a commonly found IoT daemon. If you are new to IoT or a seasoned professional you will likely learn something new in this workshop.

Node.js - The New, New Hotness
Node.js - The New, New HotnessDaniel Shaw Node.js is a popular JavaScript runtime built on Chrome's V8 JavaScript engine. It allows JavaScript to be run on the server side. Node.js uses asynchronous and event-driven programming, which makes it very fast. It has a large ecosystem of open source libraries and is used by many large companies. The document provides an introduction and overview of Node.js, how to install and use it, popular frameworks like Express and Connect, and emerging technologies like web sockets that Node.js supports.
2.2. Introduction to Arduino
2.2. Introduction to Arduinodefconmoscow George Lagoda introduces Arduino microcontrollers and their capabilities. Arduino boards can be used to hack things by exploiting vulnerabilities in communication protocols between devices and computers. The Arduino Leonardo allows creating malicious USB devices by emulating a keyboard or mouse and executing programs without permission. With libraries like Firmata, one could build a keylogger. With its programming language and libraries, Arduino provides an easy way to prototype hardware projects and explore hacking concepts.
Hardware for JavaScript Developers
Hardware for JavaScript DevelopersTarik Kelestemur This document discusses using JavaScript to program hardware devices. It provides an overview of electronic prototyping platforms like Arduino and frameworks like Johnny-Five that allow controlling hardware from JavaScript code. Johnny-Five works with many boards and allows interfacing with components like LEDs, sensors, and motors. Examples are shown of blinking an LED and building a claw controller using a servo motor and joystick. The talk aims to introduce JavaScript developers to hardware programming using approaches that don't require learning a new language like C.
Nmap for Scriptors
Nmap for Scriptorsn|u - The Open Security Community This document provides an overview of Nmap Scripting Engine (NSE) for security researchers looking to build NSE scripts. It covers the anatomy of an NSE script including required components like metadata, categories, portrules and actions. It also provides tips for scriptors like specifying the script directory, using debugging mode, and updating the script database.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptx
DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock Building 10x Organizations with Modern Productivity Metrics
10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’
Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency.
This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data.
Attendees will learn:
- Consumer awareness around data brokers and what consumers are doing to limit data collection
- How businesses assess third-party vendors and their consent management operations
- Where business preparedness needs improvement
- What these trends mean for the future of privacy governance and public trust
This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results.
News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?
