Architecture

Choosing the Right Architecture

For applications with significant domain logic: Clean or Onion Architecture can be beneficial because they both emphasize the importance of domain logic at the center.
When integrating with multiple external systems or where adaptability is important: Hexagonal Architecture is an excellent choice.
If clarity and purpose are the priority: Screaming Architecture can help make the application's business intent obvious, especially for domain-driven projects.

Hexagonal Architecture (Ports and Adapters)

Em copy file libcoccoc_tokenizer_jni.so vào một trong những thư mục /usr/java/packages/lib, /usr/lib64, /lib64, /lib, /usr/lib rồi start lại ES nhé.

Copy the following files into directory /usr/local/share/tokenizer/dicts of container:

ffmpeg

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
