6. SQL Transactions
7. DML
Redux "Bad" Practices - A List of 13 Bad Practices and How to Avoid ThemAdam Klein
"Redux forces you to write good code" - I've heard that sentence many times. In fact - it's quite easy to write bad code with Redux, as I've seen many times.In this talk I will talk about best practices and techniques with Redux, and do some live refactoring.

Dropping unique constraints in sql serverPaul Houle
I got started with relational databases with mysql, so I’m in the habit of making
database changes with SQL scripts, rather than using a GUI. Microsoft SQL Server
requires that we specify the name of a unique constraint when we want to drop it. If
you’re thinking ahead, you can specify a name when you create the constraint; if
you don’t, SQL Server will make up an unpredictable name, so you can’t write a
simple script to drop the constraint.
By now, you’ve probably heard of Akka, the JVM toolkit for building scalable, resilient and resource efficient applications in Java or Scala. With over 12 open-source and commercial modules in the toolkit, Akka takes developers from actors on a single JVM, all the way out to network partition healing and clusters of servers distributed across fleets of JVMs.
In this technical webinar, O’Reilly author and Lightbend Developer Advocate, Hugh McKee, takes you on a deep dive into advanced Akka features for enhanced application resilience, elasticity, and responsiveness.
Building on real-world examples from his past experience as an Akka developer, Hugh will show how you can take advantage of:
• Akka Multi-Data Center Clustering improves reliability across multiple data centers, availability zones or regions.
• Logically grouping related nodes in large clusters to improve stability and scalability.
• Akka Multi-Data Center Persistence for increased fault tolerance, locate data near the user, and balance the load across data centers.
• Akka Cluster Sharding in a multi data center environment, to optimize shard locality within a single data center and go Active-Active for improved resilience and availability.

Using xUnit as a Swiss-Aarmy Testing ToolkitChris Oldwood
Modern Unit Testing practices act as a conduit for improved software designs that are more amenable to change and can be easily backed by automation for fast feedback on quality assurance. The necessity of reducing external dependencies forces us to design our modules with minimum coupling which can then be leveraged both at the module, component and subsystem levels in our testing. As we start to integrate our units into larger blocks and interface our resulting components with external systems we find ourselves switching nomenclature as we progress from Unit to Integration testing. But is a change in mindset and tooling really required?
The xUnit testing framework is commonly perceived as an aid to Unit Testing but the constraints that it imposes on the architecture mean that it is an excellent mechanism for invoking arbitrary code in a restricted context. Tests can be partitioned by categorisation at the test and fixture level and through physical packaging leading to a flexible test code structure. Throw in its huge popularity and you have a simplified learning curve for expressing more that just unit tests.
Using scenarios from his current system Chris aims to show how you can use a similar format and tooling for unit, component and integration level tests; albeit with a few liberties taken to work around the inherent differences with each methodology.
No More Deadlocks; Asynchronous Programming in .NETFilip Ekberg
In this talk I go over what asynchronous programming is, and how to use it. We will discover how to avoid potential deadlocks and what the best practices are in asynchronous programming in .NET.
