3. Article 12a: No posting your own photos or videos of sports matches. Only the "organisers" of sports matches will have the right to publicly post any kind of record of the match. No posting your selfies, or short videos of exciting plays. You are the audience, your job is to sit where you're told, passively watch the game and go home.

Redis Fundamentals for .NET Developers

Redis is an open source, in-memory data store used by millions of developers as a database, cache, streaming engine, and even a message broker.
In this live sessions, Stephen Lorello, Senior Field Engineer at Redis, joins us to show the the fundamental features .NET developers show know about using Redis 

.NET 4.7.2 is for streaming data into memory between 2% (Unsafe Parse x86), 7% (Unsafe Parse x64) and 40% (Span Parse x64) slower than .NET Core. Especially the 40% speed drop for Span based Apis due to the lack of JIT support by the .NET Runtime is unfortunate.  

Redis (REmote DIctionay Server) is a very popular open-source, networked, in-memory, key-value data store, sometimes referred to as a data structure server which also comes with optional durability. Redis is well known for high performance, flexibility, provides a rich set of data structures, and a simple straightforward API.
