This is my presentation from TechBeats #3 hosted by Applause about Server-Side Swift framework called Vapor.
Swift is a great language and possibility of using it also in backend is a huge benefit for any iOS developer out there. Using Vapor is a seamless experience. With this framework creating advance APIs by iOS developer is as easy as writing simple iOS app.

Tommi Reiman (https://twitter.com/ikitommi) will be presenting Malli
(https://github.com/metosin/malli) is a fresh new data-driven data
validation and specification library for Clojure/Script. In this talk,
Tommi will give a quick introduction to Malli, compare it to prior art
including Plumatic Schema and clojure.spec and demonstrate how to
elegantly solve real-world problems with it. Also, peek beyond the
runtime validation.
Malli is a new Clojure/Script library for elegant data-driven data modelling. It is born from the real world needs of dynamic, distributed and multi-tenant systems: Schemas to describe the data should be first-class data. They should drive the runtime value transformations, web forms, rules and processes. Configuration should be explicit – no magic, macros or mutability. We should be able to infer, create and modify the models at runtime, persist and load them back from database and share over the wire, for both Clojure and ClojureScript. Like JSON Schema, but for EDN & Clojure/Script.
In this talk, I’ll walk through the core concepts, features and the lessons learned on creating Malli. I’ll also demonstrate some cool new things we can do with literal data schemas and compare it to prior art, including clojure.spec, plumatic schema and JSON Schema.
This document provides information on developing chaincode using Fabric chaincode and the development environment, YAML configuration, dev mode, chaincode programming structure, dependencies, deploying and invoking chaincode, RESTful APIs, data structures including key-value and table access, HFC APIs for user management, chaincode operations, and the gateway. It describes tools for chaincode development including Docker Compose, Golang SDK, Nodejs SDK, and windows build tools.
Clojure is a modern dynamically typed lisp. Dynamical typing is ofter associated with poor performance and runtime failures. In this talk, I'll present some of the lessons learned on building Clojure/Script systems that are both ridiculously fast and will fail fast on errors. Will compare the performance of mutable, persistent & zero-copy data structures and show how we can use interpreters and compilers to build beautiful and performant abstractions. A quick demo on how to build a simple non-blocking web server that runs idiomatic Clojure to serve millions of requests per sec.
Clojure is awesome, and it can be fast too.

Matteo Collina | Take your HTTP server to Ludicrous Speed | Codmeotion Madrid...Codemotion
In my journey through nodeland, I always wonder about the cost of my abstractions. Express, Hapi, Restify, or just plain Node.js core? require(‘http’) can reach 30k requests/sec, Express 22k, and Hapi 21k. I started a journey to write an HTTP framework with extremely low overhead, and Fastify was born. With its ability to reach an astonishing 37k requests/sec, Fastify can halve your cloud server bill. How can Fastify be so.. fast? We will discover all the not-so-secret techniques that were used to optimize it. In Fastify we reach a point where even allocating a callback is too slow: Ludicrous

The document also discusses developing and consuming web services clients using JAX-WS APIs and proxies generated from WSDL.
The document discusses various techniques for writing efficient JavaScript code, including:
1. Avoid premature optimization and focus on clean, correct code first. Optimization can then focus on specific bottlenecks.
2. Use language shortcuts like object and array literals instead of constructors to improve performance.
3. Cache frequently accessed values like DOM elements, styles, and function pointers to avoid repeated lookups.
4. Minimize DOM access and manipulation by batching changes and reducing the number of elements.
5. Use event delegation with event bubbling instead of attaching the same handler to many elements.
Presto generates Java bytecode at runtime to optimize query execution. Key query operations like filtering, projections, joins and aggregations are compiled into efficient Java methods using libraries like ASM and Fastutil. This bytecode generation improves performance by 30% through techniques like compiling row hashing for join lookups directly into machine instructions.

Beyond Horizontal Scalability: Concurrency and Messaging Using SpringBruce Snyder
The document discusses how software systems are growing larger and more complex due to increasing hardware capabilities. It describes typical application architectures and assumptions that rely on sequential execution in a single JVM. It advocates for concurrency and messaging using tools from Spring to address these challenges by removing assumptions, simplifying interactions, and allowing asynchronous and distributed execution. Specifically, it covers how Spring supports concurrency using TaskExecutor and messaging using JMS templates and message listeners to enable looser coupling and horizontal scalability beyond simply adding more machines.
The document discusses Spring support for synchronous and asynchronous JMS messaging. For synchronous messaging, Spring provides the JmsTemplate class which allows sending and receiving messages. For asynchronous messaging, Spring supports message-driven POJOs using the DefaultMessageListenerContainer and SimpleMessageListenerContainer. The DefaultMessageListenerContainer supports dynamic scaling and transactions while the SimpleMessageListenerContainer provides basic functionality.
Styles of Applicaton Integration Using SpringBruce Snyder
The document discusses styles of application integration using Spring. It covers the differences between tight and loose coupling, and how loose coupling is more difficult but provides long term benefits. Integrations are commonly tightly coupled but should be loosely coupled. Commands are used often for integrations but events are a more natural approach. Spring Integration provides tools for messaging, concurrency and integration within and between applications, as well as with external systems.
This document summarizes common problems and solutions when using ActiveMQ. It addresses questions about creating JMS clients from scratch, efficiently managing connections, consuming only certain messages, reasons for locking/freezing, when a network of brokers is needed, and using a master/slave configuration. Spring JMS and selectors are recommended over building clients from scratch. Connection pooling and caching are advised for efficiency. Selectors and proper design can filter messages. Memory, prefetch limits, and cursors impact performance and need configuration. Networked brokers improve availability while master/slave configurations provide high availability.
The document discusses common problems clients face when using ActiveMQ and provides solutions. It addresses questions around creating JMS clients from scratch, efficiently managing connections, consuming only certain messages, and why ActiveMQ may lock up or freeze. Solutions recommended include using Spring JMS instead of rolling your own client, connection pooling via PooledConnectionFactory or CachingConnectionFactory, message selectors, and ensuring proper memory settings and prefetch limits.

Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
