Building a server to manage high concurrent connections is non-trival task. For those developers that use ActionScript 3 to build games on the client side it means having a totally different skillset. Being able to use ActionScript 3 on the server to build MMO’s or port client code to the server allows developers to leverage their skills on the server.
By walking through a live game example with more then 15,000 concurrent connections running on a medium Amazon EC2 server the presentation will:
1. Introduce Linux server configuration for high concurrent connected usage.
2. Introduce Socket class based on libev library for high concurrent connection.
3. Introduce leveraging Tamarin project for ActionScript 3 on the server.

PART ONE was the Appetizer, Then DUNE: PART TWO is the Main Course
Douban friends! I'm Denis Villeneuve, and my film DUNE: PART TWO is now in theaters in the Chinese mainland. I've been deeply grateful for your support since we released Dune in 2021, and seeing everyone's anticipation for DUNE: PART TWO brings me so much joy. I hope you enjoy it as well. DUNE: PART TWO is by far the most complex and challenging film I've ever worked on, but the whole process was a lot of fun. DUNE: PART TWO is based on Frank Herbert's science fiction nov...

The document concludes with some restrictions and best practices for MySQL full-text search.
The document summarizes the key data structures used to organize data in InnoDB:
- InnoDB stores data in tablespaces which consist of data files. A tablespace header tracks free/used extents within these files.
- Data files contain fixed-size pages which are organized into extents of 1MB each. Page headers identify page types like interior, leaf, etc.
- File segments allocate ranges of pages to index trees. The root node of each index references two segment headers to allocate leaf/non-leaf pages separately.
MYSQLCLONE is a free and simple tool used to clone MySQL databases from one server to another. It can transfer the entire database including data, schemas, stored procedures, functions and events.
