This document discusses virtualization techniques such as Intel VT and VMX. It explains the ring protection model of x86 CPUs and how virtualization works by having a hypervisor sit at the highest ring/privilege level. Key virtualization concepts covered include VMX root/non-root operation, VMCS data structures, VM exits/entries, and instructions for accessing and modifying VMCS like VMPTRLD, VMPTRST, VMWRITE, VMREAD, VMCLEAR. Memory mapped and port IO virtualization techniques are also summarized.

Lightweight wrapper for Hive on Amazon EMRShinji Tanaka
?
This document describes a lightweight wrapper for Hive on Amazon EMR. The wrapper uses the Net::Amazon::EMR::Wrapper module to interact with an Amazon EMR cluster running Hive. It allows users to execute HiveQL queries, load and query data from S3, and retrieve results without having to directly interact with the EMR cluster. The wrapper handles starting and stopping the cluster and monitoring query status. Sample code is provided to demonstrate using the wrapper to create a table, load partitions, run queries, and retrieve results.
