Moving a Java team to Scala presents both challenges and benefits. Some challenges include Scala features like infix notation and higher order functions that can scare Java developers. It is important to select team members comfortable with functional programming concepts. Benefits include the Scala REPL for experimenting, compatibility with Java libraries and tools, and features like class constructors and pattern matching that allow for more concise code. With the right approach, a team can embrace Scala's advantages while overcoming unfamiliar elements.
End to end test automation with cypress
This document discusses testing AngularJS applications and compares different tools for doing so. It notes that while Selenium can be used to test Angular applications, tools like Cypress.io and Protractor make it easier by handling asynchronous loading and supporting Angular-specific locators. The document then introduces Cypress.io as an all-in-one tool that provides features like an interactive test runner, faster test execution, better debugging, and reporting capabilities. It provides a simple example of using Cypress.io and also lists some current limitations.
Developer day - AWS: Fast Environments = Fast Deployments

A Hyper-Fast Batchable Interface for Salesforce Presented in Punta del Este, Uruguay for Punta Dreamin' 2017
Артем Оробец «На пути к low-latency»
This document discusses techniques for achieving low latency in Java applications. It begins by defining latency as the time interval between stimulation and response. For applications, total response time equals service time plus waiting time for service. Latency requirements of less than 100ms are given as an example of low latency. The document then explores specific techniques for reducing latency, such as avoiding context switching through thread pooling, optimizing logging through asynchronous approaches, addressing DNS lookup delays, and monitoring and tuning garbage collection. Overall it provides guidance on analyzing and improving various aspects of application performance to meet strict low latency goals.

Asynchronous Apex .pptx
The document discusses asynchronous Apex in Salesforce, including future, batch, queueable, and schedulable Apex. It provides examples of when to use asynchronous Apex over synchronous Apex to avoid governor limits. It explains key differences like higher governor limits for asynchronous Apex and the ability to call other asynchronous jobs. The presentation agenda is outlined and definitions of synchronous and asynchronous Apex are provided.
A first look into the Project Loom in Java
Project Loom aims to bring asynchronous programming to Java with virtual threads. Virtual threads allow blocking code to run asynchronously by scheduling continuations across lightweight threads. This avoids the "blue world" problem of rewriting synchronous code for asynchronous systems. It also enables scaling applications by utilizing non-blocking I/O without changing existing code or libraries. While virtual threads are not yet production-ready, Project Loom has the potential to improve scalability for Java applications without a major paradigm shift.
Salesforce asynchronous apex
When executing something synchronously, you wait for it to finish before moving on to another task. Asynchronously, you can move on before it finishes. Future methods, Queueable Apex, and Batch Apex allow asynchronous execution in Apex. Future methods are best for long-running methods or callouts. Queueable Apex allows job chaining and passing complex types. Batch Apex is best for large data volumes processed in batches. Continuations allow asynchronous callouts from Visualforce pages.
C# Async/Await Explained
The document discusses asynchronous programming with async and await in C#. It explains that async and await were introduced to address issues with threading like overhead and blocking. Async methods use threads efficiently from the thread pool rather than creating new threads. Await yields threads rather than blocking them. The document demonstrates async programming and best practices like using Task instead of async void. It recommends using async for I/O bound work since it can improve performance over synchronous code.

Database Core performance principles
This document discusses database performance core principles and how moving business logic out of the database and into application servers can negatively impact performance. The key points are:
1. Oracle databases are process-based and processes need to get CPU time quickly, stay on the CPU, and experience few involuntary context switches.
2. Moving business logic out of the database and into many small calls results in high call counts, more voluntary sleeps as processes switch contexts, and potential oversubscription of processes leading to involuntary sleeps.
3. This violates database performance principles and leads to inconsistent response times, lower throughput, and inefficient use of computing resources across database and application servers due to increased overhead of switching processes.
Keeping
Donatas Mažionis, Building low latency web APIs
This document discusses latency and strategies for improving latency when building APIs and services. It describes using percentiles instead of averages to measure latency, and tools like HdrHistogram and Finagle for tracking latencies. It also discusses experiences using Redis, Cassandra and Aerospike for low latency, and strategies for connecting to Cassandra and handling timeouts. Key takeaways are around not relying on averages, challenges of scaling in .NET, choosing the right NoSQL solution, and that blocking is not always bad if it reduces timeouts.
Performance Oriented Design
This document discusses performance-oriented design and what metrics should be measured. It emphasizes that performance is important and organizations should care about it. Key metrics that should be measured include arrival rate, service time, throughput, queues, method counts, response times, and other application and system-level metrics. References for further reading on performance engineering and capacity planning are also provided.
ExpressionEngine - Simple Steps to Performance and Security (EECI 2014)
This document discusses steps website administrators can take to improve the performance and security of websites built with ExpressionEngine. It begins by demonstrating through benchmarks how upgrading to newer versions of PHP can significantly improve performance. It then provides recommendations for optimizing ExpressionEngine settings and plugins, and using caching, CDNs and hardware. For security, it advises keeping software updated, restricting access, using firewalls and HTTPS, and securely managing user accounts and publishing workflows. The overall message is that ongoing performance and security efforts can directly benefit websites and should be made part of the development process.
End to-end async and await
The document discusses asynchronous programming using async and await in C#. It begins by explaining what asynchronous programming is and why it is useful for improving app responsiveness and simplifying asynchronous code. It then describes how async and await works by generating state machines and using continuation tasks. The document covers some gotchas with async code as well as best practices like naming conventions. It provides references for further reading on asynchronous patterns, tasks, and unit testing asynchronous code.

Salesforce Lightning Data Service
Lightning Data Service allows developers to build custom components that can access and manipulate standard and custom object data without writing any Apex code. It provides a standard controller that handles data retrieval, caching, offline access, and notifications of record changes for custom components. Developers simply add the <force:recordData> component to their custom components to access and display record data. Current limitations include lack of support for some standard objects and formatted field values. The roadmap includes general availability in Winter '18 along with additional features like bulk data support and server-side triggers.

In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
