Blockchain has emerged as a decentralized platform for managing digital assets and executing 'smart contracts', i.e., user-defined code. While blockchain's suitability for a given use case should always be scrutinized, it does have the potential to disrupt many of the connection points between individuals, companies, and government entities. In this keynote talk, I will provide an overview of what architects and developers need to know in order to build blockchain-based applications, and how it relates to the cloud and software services. Among others, I will cover blockchain-as-a-service concepts, as well as architectural concerns and model-driven engineering for blockchain applications, the latter also in relation to collaborative business processes. To highlight some of the challenges, I will discuss insights from a project on "programmable money", i.e., blockchain-based money for conditional payments where the money itself checks whether it can be spent in a certain way at the point of payment. Finally, I will touch on insights into current adoption of blockchain.

WebKit is a web rendering engine (HTML, JavaScript, CSS) with a generic part (WebCore, JSEngine), and 'ports' for specific platforms that implement bits like rendering, networking or multimedia. In the WebKit community, companies&individuals cooperate to evolve a complex codebase. Given the popularity of HTML5 and web tech, WebKit is a key open source project. Recently, Google announced Blink, a fork of WebKit, with consequences for the project still difficult to predict. Igalia's Browsers team maintains the WebKitGTK+ port and is top contributor to WebCore, JSC, V8, other ports (EFL, Clutter, Qt), and Blink. The talk will review the past/present/future of WebKit/Blink, their dynamics and development process, the relationship with the Linux ecosystem, and will give information about how to contribute to or use both projects.
The document discusses the Crosswalk project and the Intel XDK. It provides an overview of the Intel XDK, which is a free integrated development environment (IDE) and toolkit that allows developers to build hybrid mobile apps using HTML5, JavaScript, and CSS that can be deployed across multiple platforms. It also discusses Crosswalk, which is an open source project that provides a modern HTML and JavaScript runtime based on Chromium for developing advanced Android apps with web technologies.
The Open Hardware PowerPC Notebook designed around GNU/Linux will be showed at NOI Techpark. We had presented here its motherboard design in 2018. We will updates regarding last developments for u-boot AMD video drivers, re-design of heat pipes, and CE test certification process. We will give future availability milestones of this notebook and details regarding the GNU/Linux distributions or other OS that could runs on it.
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.

Our online community provides workshops, 1-1 sessions, and an intensive building period over 4 weeks to develop decentralized finance projects, with a submission deadline of November 14th for a demo, codebase, and optional presentation to be reviewed at a finale and prizegiving on November 30th. The document discusses principles of crypto such as being decentralized, self-sovereign, and permissionless, and explores ideas around governance, cross-chain applications, traditional financial products in crypto, custody, onboarding, fiat gateways, gaming, and existing projects.
The document provides an overview of how mining works in Filecoin, including:
1) Sectors are the basic unit of storage in Filecoin and sectors must be sealed and proven to provide storage power and mine blocks.
2) The sealing process prepares sectors for storage and involves precommitment phases and committing the sector.
3) Proving ensures sectors are stored by generating WindowedPoST and WinningPoST proofs on a regular basis and when winning elections.
4) Lotus is the main Filecoin mining software that coordinates the sealing and proving processes. Miners can use various architectures from single to multiple box setups.
The document discusses the principles and potential applications of cryptocurrency and decentralized technologies. It outlines that cryptocurrencies should ideally operate in a permissionless, decentralized, and open manner. It then explores potential real-world uses of cryptocurrency in areas like custody, onboarding, supply chains, identity, data, art, finance, and governance. Finally, it encourages the reader to consider their skill level and time commitment as they decide how to get involved and contribute to building out these cryptocurrency applications.
The document is a presentation on Substrate and building blockchains. It introduces Substrate and its benefits like modularity and forkless upgrades. It discusses building a forum blockchain as an example, including storing posts, authors, and contents. It outlines the steps to build the first blockchain using Substrate, launching it and connecting to Polkadot.js. Finally, it discusses next steps like pallets, cryptography, and deploying to production as a parachain on Polkadot.
This document provides code examples for interacting with the Filecoin bridge using Textile's storage libraries for Ethereum and NEAR. It shows how to initialize storage on each chain, add a deposit to the bridge, store a file, and check the storage status. The Ethereum example imports the ethers library and initializes storage after requesting sign in. For NEAR, it imports the near-api-js library, connects a wallet, and initializes storage after requesting sign in. Both examples store a file, check the status, and include calls to add a deposit to the bridge and get the file ID and CID.
This document provides an agenda and overview of SubQuery, an open source project that allows developers to index, transform, and query Substrate chain data. It discusses problems with current query speeds and parachain diversity that SubQuery aims to address. The basics of SubQuery are explained, including the components needed and key concepts like the manifest file, GraphQL schema, and mapping files that define how chain data is extracted, transformed, and persisted. Hands-on exercises are proposed to build a sample project. Production infrastructure for hosting SubQuery projects is also introduced.

This time, we're diving into the murky waters of the Fuxnet malware, a brainchild of the illustrious Blackjack hacking group.
Let's set the scene: Moscow, a city unsuspectingly going about its business, unaware that it's about to be the star of Blackjack's latest production. The method? Oh, nothing too fancy, just the classic "let's potentially disable sensor-gateways" move.
In a move of unparalleled transparency, Blackjack decides to broadcast their cyber conquests on ruexfil.com. Because nothing screams "covert operation" like a public display of your hacking prowess, complete with screenshots for the visually inclined.
Ah, but here's where the plot thickens: the initial claim of 2,659 sensor-gateways laid to waste? A slight exaggeration, it seems. The actual tally? A little over 500. It's akin to declaring world domination and then barely managing to annex your backyard.
For Blackjack, ever the dramatists, hint at a sequel, suggesting the JSON files were merely a teaser of the chaos yet to come. Because what's a cyberattack without a hint of sequel bait, teasing audiences with the promise of more digital destruction?
-------
This document presents a comprehensive analysis of the Fuxnet malware, attributed to the Blackjack hacking group, which has reportedly targeted infrastructure. The analysis delves into various aspects of the malware, including its technical specifications, impact on systems, defense mechanisms, propagation methods, targets, and the motivations behind its deployment. By examining these facets, the document aims to provide a detailed overview of Fuxnet's capabilities and its implications for cybersecurity.
The document offers a qualitative summary of the Fuxnet malware, based on the information publicly shared by the attackers and analyzed by cybersecurity experts. This analysis is invaluable for security professionals, IT specialists, and stakeholders in various industries, as it not only sheds light on the technical intricacies of a sophisticated cyber threat but also emphasizes the importance of robust cybersecurity measures in safeguarding critical infrastructure against emerging threats. Through this detailed examination, the document contributes to the broader understanding of cyber warfare tactics and enhances the preparedness of organizations to defend against similar attacks in the future.

An All-Around Benchmark of the DBaaS MarketScyllaDB
The entire database market is moving towards Database-as-a-Service (DBaaS), resulting in a heterogeneous DBaaS landscape shaped by database vendors, cloud providers, and DBaaS brokers. This DBaaS landscape is rapidly evolving and the DBaaS products differ in their features but also their price and performance capabilities. In consequence, selecting the optimal DBaaS provider for the customer needs becomes a challenge, especially for performance-critical applications.
To enable an on-demand comparison of the DBaaS landscape we present the benchANT DBaaS Navigator, an open DBaaS comparison platform for management and deployment features, costs, and performance. The DBaaS Navigator is an open data platform that enables the comparison of over 20 DBaaS providers for the relational and NoSQL databases.
This talk will provide a brief overview of the benchmarked categories with a focus on the technical categories such as price/performance for NoSQL DBaaS and how ScyllaDB Cloud is performing.

Connect your GitHub account (min. 3 months
old with activity within the last 1 month)
Transfer the ICP to the NNS App
Click the “Canister” tab
Create a new canister
Specify how much ICP to be
converted into cycles
Success - you have created
a canister with cycles!
Obtain your principal ID in the terminal
with dfx identity get-principal
Obtain your ledger account ID in the
terminal with dfx ledger account-id
Transfer ICP from the exchange to your
ledger account ID
Create an empty canister with ICP -> cycles with dfx -
- network ic create-canister <principal-
indentifier>- - amount <icp-tokens>
Install cycles wallet code to your empty canister with dfx
identity - - network ic deploy-wallet <canister-identifer>
Access your cycles wallet UI with [canister ID].rw.ic0.app
in the browser to manage your canisters & cycles
You have successfully created a Cycles Wallet, as well as a
canister topped up with cycles!
25. Tools & Resources
Overview of Ecosystem
Internet Computer Showcase: Here you can find a snapshot of apps/tools in the IC ecosystem, with links
Getting Cycles
Getting Cycles (Using the Terminal): Here are instructions Igor has created to create a canister with cycles
in the terminal
Getting Cycles (Using the NNS App): Here are instructions Kyle has created to create a canister with
cycles in the NNS App
Cycles Faucet (Easiest Path - Recommended): You can obtain $100 worth of free cycles here, if you have
a Github account at least 3 months old with activity in the last 1 month
Tools for Developers to Build on the IC
DFINITY Canister SDK: Motoko SDK to build on the IC. Motoko is the programming language we created,
optimized for the IC.
Note: Eventually, developers will be able to build on the IC in all languages compatible with
WebAssembly (e.g., C, C++, Go, C#, TypeScript, Java, Kotlin, Python, PHP, etc), so they do not need to
learn Motoko
Rust CDK: Rust SDK to build on the IC
Vessel Package Manager: A simple package manager for the Motoko programming language.
Motoko VS Code Extension: Syntax highlighting for the Motoko programming language in VS Code.
26. Tools & Resources
Agent JS: A collection of libraries and tools for building software around the Internet Computer, in JavaScript.
Sudograph: A GraphQL database for the Internet Computer
Cycles Wallet: A wallet UI for cycles (our equivalent of gas with Ethereum)
Motoko Playground: A sandbox to write and test Motoko code
Quill: An open-source toolkit to manage cold wallet storage of the ICP utility token
Community-created Resources
Coding with Kyle: Video series created by Kyle on how to build an app in Motoko (3 episodes will be out this week)
Awesome DFINITY repo: You can find several examples of code here
ic.rocks: Block explorer for the IC (you can view transactions here)
Plug: Browser-based wallet extension created by Harrison Hines, former Consensys alum, & his team
Stoic Wallet: Wallet created by Toniq Labs
Fleek: Netlify for the open web created by Harrison Hines, former Consensys alum, & his team
Widgets
Page View Widget: Kyle Peacock has created a page view canister, so you can track how many page views your
site has
