Oracles
Blockchain oracles are third-party services that provide smart contracts with external information from outside the blockchain. They serve as a bridge between blockchains and the external world. An example use case demonstrated connecting a smart contract deployed on the Ropsten testnet to a Raspberry Pi device and safe, where the smart contract could be unlocked by paying above a set price, triggering the Raspberry Pi to open the safe. The demo code included creating a smart contract to control locking/unlocking a safe, deploying it to Ropsten, connecting a Raspberry Pi to listen for contract events and control an LED, and simulating unlocking the safe by paying to the contract.

Ethereum Contracts - Coinfest 2015
Ethereum contracts are small pieces of code that can be deployed to the Ethereum blockchain to execute autonomously. They are written in the Solidity language and can store and transfer value and data. To develop contracts, they must be compiled from Solidity to bytecode, deployed to the blockchain, and can then be interacted with by users via transactions that call functions defined in the contract's application binary interface (ABI). Examples of suitable contracts include tokens, crowdfunding, voting systems, and decentralized autonomous organizations.

Kakfa summit london 2019 - the art of the event-streaming app
Have you ever imagined what it would be like to build a massively scalable streaming application on Kafka, the challenges, the patterns and the thought process involved? How much of the application can be reused? What patterns will you discover? How does it all fit together? Depending upon your use case and business, this can mean many things. Starting out with a data pipeline is one thing, but evolving into a company-wide real-time application that is business critical and entirely dependent upon a streaming platform is a giant leap. Large-scale streaming applications are also called event streaming applications. They are classically different from other data systems; event streaming applications are viewed as a series of interconnected streams that are topologically defined using stream processors; they hold state that models your use case as events. Almost like a deconstructed real-time database.
In this talk, I step through the origins of event streaming systems, understanding how they are developed from raw events to evolve into something that can be adopted at an organizational scale. I start with event-first thinking, Domain Driven Design to build data models that work with the fundamentals of Streams, Kafka Streams, KSQL and Serverless (FaaS).
Building upon this, I explain how to build common business functionality by stepping through the patterns for: – Scalable payment processing – Run it on rails: Instrumentation and monitoring – Control flow patterns Finally, all of these concepts are combined in a solution architecture that can be used at an enterprise scale. I will introduce enterprise patterns such as events-as-a-backbone, events as APIs and methods for governance and self-service. You will leave talk with an understanding of how to model events with event-first thinking, how to work towards reusable streaming patterns and most importantly, how it all fits together at scale.

Docker In Bank Unrated
Docker on a local machine and Docker in production — are two big differences. It's easy to play with technology but it's hard to do something real for many customers.
Half a year ago inside of Alpha Laboratory (division of Alfa-Bank) we've started building new microservices architecture for one of our pilot projects. We've almost completely changed a stack of the used technologies on a frontend and significantly changed it on a middle layer. For package and distribution we have choosen Docker. Two months ago we've deployed project to production and have opened service for clients.
In the report the following topics will be covered:
- reasons of a choice Docker;
- why Docker without other tools is not enough for a production;
- what stack of technologies we used in our solution;
- what advantages we've got;
- what problems have been faced and how we've solved them.

ERC20
1) ERC20 is a standard interface for smart contracts on Ethereum that defines basic functionality for fungible tokens like querying balances and transferring tokens.
2) It allows tokens to be sent, received, and approved for transfer on the Ethereum blockchain through standard functions like transfer, approve, and transferFrom.
3) These functions can be called through JSON-RPC calls to interact with ERC20 tokens on Ethereum, such as querying the total token supply or transferring tokens to another address.
[LDAPCon 2015] The OpenID Connect Protocol
OpenID Connect is a new Single Sign On protocol, built on top of OAuth 2.0. Led by OpenID foundation, he very different form OpenID 1.0 and OpenID 2.0, now marked as obsoletes.
This paper will let you discover this new standard, by first explaining what is OAuth 2.0 and why it is not an identity protocol. Then the OpenID Connect protocol will be described, and to conclude, we will do a comparison with the other main SSO standard which is SAML.
Stellar for payments, money transfer & remittances
The document discusses using the Stellar blockchain to enable fiat settlements between banks, EMIs, and other financial institutions without needing APIs. It proposes creating "Peso tokens" on Stellar that represent fiat currencies in a 1:1 ratio. These tokens can be exchanged on the Stellar decentralized exchange, allowing instant and low-cost transfers between entities. International currency conversions are also possible using multiple currency pairs on Stellar. Addresses or QR codes would represent users' accounts.

Approaches to connectivity between blockchains with examples of Chainlink, Cosmos, Kusama, and Polkadot
Oracles
Blockchain oracles are third-party services that provide smart contracts with external information from outside the blockchain. They serve as a bridge between blockchains and the external world. An example use case demonstrated connecting a smart contract deployed on the Ropsten testnet to a Raspberry Pi device and safe via an oracle. When the "Unlock" event was detected from the smart contract, the oracle triggered the Raspberry Pi to blink an LED, and when the "Lock" event occurred it stopped the blinking. The full document provided details on oracle architecture and functions, different types of oracles, and code samples for interacting with the smart contract and Raspberry Pi.

Why Apache Kafka Clusters Are Like Galaxies (And Other Cosmic Kafka Quandarie...
Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.
Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/
