Bitcoin is a digital currency where new bitcoins are "mined" by computers competing to solve complex math problems. This mining process adds transactions to the blockchain, a public record of all bitcoin transactions that is maintained by consensus among users. While bitcoin saw major hype last year, the mining arms race has intensified and the glory days of mining may already be over as it becomes increasingly difficult to earn new coins. A bitcoin wallet is simply an application that allows users to access their coins on the blockchain.

Lopug docker end_of_distro
The document discusses how Docker containers currently reuse existing operating system distributions, which is problematic. It suggests moving away from relying on full operating systems inside containers towards a more minimal model. This would allow for more consistency between what a host system runs versus inside containers. The document outlines several recommendations, including starting containers from scratch rather than existing distributions and being more specific about versions for packages installed.
Consumerisation – what does it mean to a developer?
Consumerisation refers to allowing employees to use their personal devices for work. This document discusses strategies for supporting consumerisation. It suggests understanding why employees want to use their devices, then using containers and frameworks to securely deliver work applications and enforce policies. Containers isolate work applications and data from personal use and provide controls like authentication and encryption. Frameworks like hybrid and native allow building applications that meet diverse user and use case needs while containers enforce consistent security. The optimal approach balances user experience and enterprise security requirements.
Big data debunking some of the myths
A look at the practicalities of big data and why algorithms (and those who understand them) are important
Docker - a lot changed in a year
Docker has developed rapidly in the past year. It started as a simple tool used to package applications into containers using LXC but has since replaced LXC with its own containerization technology. Major releases introduced compatibility with mainstream Linux distributions, a regular release cycle, and production support. The ecosystem around Docker is also expanding rapidly with new tools for container orchestration, composition, and platforms as a service being built using Docker. While Docker has come a long way, there is still work to be done in areas like security and managing container lifecycles and dependencies.
BLN Making it Mobile - financial services example
The document discusses frameworks and containers for developing mobile applications. It describes the characteristics of web, hybrid, and native frameworks, noting that web frameworks allow cross-platform development but have limited local state and no camera/GPS access, while native frameworks are not cross-platform but have better performance and full feature access. It presents a diagram showing how mobile SDKs, in-house containers, web/hybrid/native frameworks, and third-party apps relate when developing mobile applications.
IET harnessing big data tools in financial services
This document discusses harnessing big data tools in financial services. It describes three types of big data problems: those with high data volume and low algorithm complexity, those with any data volume but high algorithm complexity, and those inherently involving big data. It also covers implications for data security, governance, and data center infrastructure, concluding that big data tools require maturing security controls while data centers will utilize many energy efficient servers with local storage.
Financial Services - Head in the Cloud
The document discusses cloud computing in the financial services industry. It begins with an agenda that outlines discussing the definition of cloud computing, common excuses for not adopting cloud, how financial services are already using cloud, and which banks may become the prime brokers for tier 1 clients in cloud. It then addresses each of these points in subsequent slides, explaining what cloud computing is, rebutting excuses around security and regulatory issues, providing examples of how markets, trading facilities, and prime brokerage currently utilize aspects of cloud, and envisioning how banks may expand their services as cloud offerings. It concludes by thanking the audience and providing links for further information.
Cloudcamp London - Drones
Drones are becoming increasingly popular recreational devices but also enable questionable uses that could threaten security. The author predicts that drones will continue growing as toys until one is eventually used in a terrorist attack, causing politicians to overreact and ban most drones despite their beneficial applications. This regulatory overreach would frustrate hackers and limit drones' positive potential uses outside of law enforcement.

The application security controller
Cloud Expo Europe presentation on the convergence of unified threat management and application delivery controllers into virtual appliances
Security protocols in constrained environments
Security protocols like SSL, TLS, and SSH can be implemented on low-power embedded systems but with some challenges. On low-end 8-bit AVR microcontrollers like those in most Arduinos, security protocols are not feasible due to insufficient SRAM. Mid-to-high-end ARM-based microcontrollers can support security protocols with effort to configure libraries, keys, and cipher suites. Linux-based systems like the Raspberry Pi easily support security protocols using package managers. The main issues are limited memory on low-end systems and needing to handle libraries, keys, and cipher suites for higher-end embedded platforms.
Where is my big data: security, privacy and jurisdictions in the cloud
This document summarizes Chris Swan's presentation on big data security, privacy, and jurisdiction in the cloud. The presentation covers Swan's background in technology, defines big data, discusses cloud security concerns and challenges of regulation across jurisdictions. It concludes by suggesting some steps individuals can take to protect their data, such as only using services from providers with strong privacy policies and avoiding services from countries with surveillance laws that compromise privacy.
IPexpo - What is DevOps, and why should infrastructure operations care?
DevOps is about changing an organization's culture to prioritize collaboration between development and operations teams through automation and continuous delivery practices. It requires moving beyond simply purchasing new tools and instead focusing on operational design and breaking down silos between teams through culture change. While challenging, DevOps aims to help organizations streamline processes, treat infrastructure as automated and disposable, and deliver value to customers faster through practices like continuous integration and delivery.
CloudCamp London 15 Sep 2016 - WebVR
WebVR allows development of virtual reality experiences using only a mobile phone and cardboard viewer. The document demonstrates basic code for rendering 3D objects like spheres, cubes, and cylinders in a VR scene. It also provides an example of replacing the default scene with a dinosaur model running along a 3D track, showing how assets can be imported and interactive elements added.
Deploying Security at Scale
The document summarizes a presentation about deploying security at scale. It discusses the tradeoffs of building security controls into systems versus bolting them on later. It also covers how the Let's Encrypt initiative has made certificates free and easy to consume via APIs. However, the presentation argues that APIs alone are not sufficient for security and events still need to be monitored and addressed. The overall message is that while technologies like APIs and Docker help, more work is still needed in areas like security monitoring, control of metadata, and integrating systems to enable security at scale.
Digital Banking Creates Opportunity for Customer-Focused Finance
The document discusses how digital banking is creating opportunities for customer-focused finance. It notes that the customer experience is being redefined and the landscape is changing, including in payments disruption. It advocates for operational efficiency through designing infrastructure for agility. Achieving operational efficiency allows banks to invest in an agile infrastructure like hyper-converged systems that provide benefits like more frequent deployments and faster recovery from failures. The talk summarizes that the changing landscape, operational efficiency, and agile infrastructure are key topics.
How do I do DevOps when all I have is Ops?
The document discusses how to implement DevOps practices when an organization only has operational capabilities. It recommends focusing on operational data mining to enable continuous learning and experimentation. Specific approaches include training operations staff on infrastructure as code using tools like Git, Ansible, and Jenkins. Emphasis is placed on empowering frontline staff by giving them insights from operational data to identify constraints and make improvements. The overall goal is to help organizations gain the agility benefits of DevOps through incremental cultural and process changes rather than waiting for full development capabilities.

SOOCon24 - Showing that you care about security - OpenSSF Scorecards
Open Source Security Foundation (OpenSSF) Scorecards provide a way for open source users to determine whether maintainers are being diligent about securing their link in the software security supply chain. Practices such as pinning dependencies, branch protection, required reviews, continuous integration tests etc. are measured to provide a score and accompanying badge.
This presentation will provide a walkthrough of the steps involved in securing a first repository, and then what it takes to repeat that process across and organization with multiple repos. It will also look at the ongoing maintenance involved once scorecards have been implemented, and how aspects of that maintenance can be better automated to minimize toil.

Fluttercon Berlin 23 - Dart & Flutter on RISC-V
Arm has dominated the mobile space since the dawn of smartphones, but systems based on the open source RISC-V instruction set architecture will bring new choices for manufacturers and us, their customers. RISC-V SDKs showed up in the Dart dev channel in Apr 22, but it's still pretty hard to build stuff due to lots of missing dependencies. As always happens with new stuff, the hardware people are waiting for broader software support, and the software people are waiting for a larger hardware installed base. This talk examines the forces that are driving RISC-V forward, and what developers can expect from a world that will have RISC-V devices, mobile phones, tablets and cloud services.

Flutter SV Meetup Oct 2022 - End to end encrypted IoT with Dart and Flutter
Walkthrough of how Internet of Things (IoT) devices can run full stack Dart and connect to Flutter apps using end to end encryption to provide security and privacy.
QConSF 2022 - Backends in Dart
Dart's popularity has surged in the past few years, as it's the language behind Flutter - Google's cross platform front end framework. That's now driving a notion of 'Full Stack Dart', where if you've spent time learning Dart for the front end, why not also use it for the back end.
London IoT Meetup Sep 2022 - End to end encrypted IoT
Your thing, your data.
An overview of why end-end encryption is desirable for the Internet of Things (IoT), and how it can be done using personal data stores such as atSigns on the atPlatform.
Flutter Vikings 2022 - End to end IoT with Dart and Flutter
Things need apps to manage them, which Flutter is great for, providing an easy way to build cross platform support. But things also need to get their data (securely and privately) to their apps, and Dart can be used for that. This presentation will walk through a use case demonstrated at Mobile World Congress (and now open sourced) that uses Dart to read sensor data through to Flutter for user presentation.
EMFcamp2022 - What if apps logged into you, instead of you logging into apps?
As a hacker and engineer I've been interested in identity and privacy since the dawn of the Internet and the online services it's enabled. For the past year I've been helping to build and open source The @ Platform, which inverts the usual model by giving everybody (and every thing) their own place to store data and control who (and what) has access to it. This talk will give an overview of the platform and its underlying protocol, and illustrate how it can be used to build privacy preserving apps and Internet connected things. It will also cover how the platform can be self hosted on devices like the Raspberry Pi, and how people can get involved in the open source community growing around it.
Devoxx UK 2022 - Application security: What should the attack landscape look ...
What do we need to do in the next few years to ensure that the attack landscape for 2030 isn't the same as 2020? Better languages and frameworks have already brought substantial improvements in memory safety, eliminating whole classes of vulnerabilities caused by buffer overflows.Yet despite a major reshuffle in 2021, the OWASP top 10 remains full of things that boil down to a lack of input validation. An issue that has bedevilled tech since its inception. We're all told that we shouldn't trust the input to our programs, and that validation is our best defence. But developers get precious little help on that front from today's languages and frameworks; something that can and should change. This talk will examine a hypothetical evolution of TypeScript - ValidScript, to consider a future where input validation is baked in.
Flutter Festival London 2022 - End to end IoT with Dart and Flutter
A walk through of a demo system that was built for Mobile World Congress 2022 showing how Dart can be used to read data from a biometric sensor and send it to a Flutter front end application using end to end encryption.
Full Stack Squared 2022 - Power of Open Source
The document discusses the power of open source software and how people can get involved. It begins with an introduction of the author and covers the three types of "free" that define open source - free like beer meaning no cost, free like speech meaning freedom over the code, and free like puppy meaning ongoing maintenance is required. Famous people in open source like Richard Stallman, Eric Raymond, and Linus Torvalds are profiled. The document outlines how readers can get involved through contributing code, being considerate of maintainers, and participating in challenges. It concludes with contact information and a call for questions.
Flutter Vikings 2022 - Full Stack Dart
Flutter provides an excellent way to build Android, iOS, web and desktop apps, but what about the back end services? Full stack Dart is all about using that investment in Dart programming to build the services used by applications, whether it's in the cloud or on the Internet of Things. This presentation will look at the tradeoffs between just in time (JIT) and ahead of time (AOT) compilation, Dart on Docker, the Functions Framework for Dart, Profiling and Performance Management. Choices of back end architecture (x86_64 vs Arm) will also be examined, along with some of the challenges this can present for Continuous Delivery.

JavaLand 2024: Application Development Green Masterplan
My presentation slides I used at JavaLand 2024
Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
