[HDGEM] Dynamically typed is convenience

Most scripting languages are dynamically typed.  You can usually create new variables without declaring the variable type, and you can reuse variables to store objects of different types. Also, scripting languages tend to perform many type conversions automatically, for example, converting the number 10 to the text "10" as necessary.

[HDGEM] Browsix is a framework that bridges the considerable gap between conventional operating systems and the browser

Browsix enables unmodified programs expecting a Unix-like environment to run directly in the browser.  Browsix does this by mapping low-level Unix primitives, like processes and system calls, onto existing browser APIs, like Web Workers and postMessage.

Browsix brings all of these abstractions into unmodified browsers, and is isolated and secured to the same extent any normal web page is: at the level of the browser tab.

[HDGEM] DocumentDB databases can now be used as the data store for apps written for MongoDB.

This means that by using existing drivers for MongoDB databases, your application written for MongoDB can now communicate with DocumentDB and use DocumentDB databases instead of MongoDB databases. In many cases, you can switch from using MongoDB to DocumentDB by simply changing a connection string. Using this functionality, customers can easily build and run MongoDB database applications in the Azure cloud - leveraging DocumentDB's fully managed and scalable NoSQL databases - while continuing to use familiar skills and tools for MongoDB.

[HDGEM] Best practices for using AWS Lambda

Write your Lambda function code in a stateless style, and ensure there is no affinity between your code and the underlying compute infrastructure. Instantiate AWS clients and database clients outside the scope of the handler to take advantage of connection re-use. Make sure you have set +rx permissions on your files in the uploaded ZIP to ensure Lambda can execute code on your behalf. Lower costs and improve performance by minimizing the use of startup code not directly related to processing the current event. Use the built-in CloudWatch monitoring of your Lambda functions to view and optimize request latencies. Delete old Lambda functions that you are no longer using.
