Microservice Bots

What they are and why you should use them

Introduction

Recently more and more chatbots appear, the overall chatbot market grows and the platform for it grows as well. Today we are taking a close look at what benefits creating a microservice chatbot on Discord - (a communication platform mainly targeted at gamers) would provide.

The concepts and ideas explained in this whitepaper are geared towards bots with a bigger userbase where the limits of a usual bot style appear with a greater effect

Install and Create Emulators using AVDMANAGER and SDKMANAGER

TL;DR

For an emulator that mimics a Pixel 5 Device with Google APIs and ARM architecture (for an M1/M2 Macbook):

List All System Images Available for Download: sdkmanager --list | grep system-images
Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"

Many tools do not fully remove metadata, but just remove the link with in the metadata table. The data are thus still available in the PDF file itself.

While a lot of people rely on Exiftool to remove metadata, it actually does the same in PDFs. If you remove metadata with exiftool -all= some.pdf, you can always restore the data with exiftool -pdf-update:all= some.pdf.

There are several options to remove PDF metadata safely:

Option 1 : Exiftool with qpdf

Remove metadata with exiftool : exiftool -all= some.pdf
Then remove ununsed objects with qpdf : qpdf --linearize some.pdf - > some.cleaned.pdf
