# AWS LAMBDA tutorialspoint SIMPLY EASY LEARNING www.tutorialspoint.com https://twitter.com/tutorialspoint ## About the Tutorial AWS Lambda is a service which computes the code without any server. basics of AWS Lambda and its programming concepts in simple and easy way. This tutorial will give you enough understanding on various functionalities of AWS Services to be used with AWS Lambda with illustrative illustrative examples. ## Prerequisites To work with AWS Lambda, you need a login in AWS. The details on how to get free login is discussed in tutorial. AWS Lambda supports languages like NodeJS, Java, Python, C#

## +23 ## Optimizing Away Virtual Functions May Be Pointless ## SHACHAR SHEMESH Slide #2 - who am I?  ## DO NOT ENTER reviewer's notes: There are interesting technical details and surprising conclusions that virtual functions can be actually faster. Since CPU architectures are mentioned, I'd expect to see deep assembly vtable lookup. Does it even matter? ### WEKA DriveU.auto ## Conclusions - The notion that “virtual functions are slower” is flat out wrong. ○ Which is not to say they are faster o Some of the suggested alternatives
