How to run Android Studio Emulator (AVD) without lags

Running ARMv7/ARM64 image on x86_64 host with maximum emulation performance:

1. Close all Google Chrome instances and shutdown your antivirus.

2. Better create ARMv7 image without Google APIs.

3. Fix "cannot add library /usr/local/android-sdk/emulator/qemu/darwin-x86_64/lib64/vulkan/libvulkan.dylib: failed":
   λ ln -s ${ANDROID_SDK_ROOT}/emulator/lib64 ${ANDROID_SDK_ROOT}/emulator/qemu/darwin-x86_64/lib64

Secure Sockets Layer or SSL is a secure protocol, which is the reason why secure E-Commerce and E-Banking is possible. It has become the de facto standard for secure and safe only transactions. When Netscape first developed SSL, the main aim or motive behind it was to ensure that the client and host can communicate or transfer data and information securely.

 

What SSL does in short would be, encrypt data at the sender’s end and decrypt data at the receiver’s end. This encrypted data cannot be picked up or hijacked in between and any tampering would not only be very difficult, it would easily be detected.  Not only that, SSL also provides for two-way authentication i.e. verification of the client’s and the server’s identity.

 

The various functions or features of SSL can be divided into three main categories-:

DTrace: The Reverse Engineer’s Unexpected Swiss Army Knife

Abstract

This paper will examine how DTrace, a kernelbased dynamic scriptable tracer, can be effectively used for reverse engineering tasks. DTrace offers an unprecedented view of both user and kernel space, which has many interesting implications for security researchers. In this paper we will introduce DTrace, comparing it to existing debuggers and tracers.
