I am passionate about Ruby, but its execution time compared to other languages is extremely high, especially when we want to use more complex algorithms. In general, data structures in interpreted languages become incredibly slow compared to compiled languages. Some algorithms such as ´n-body´ and ´fannkuch-redux´ can be up to 30 times slower in Ruby than Go. This is one of the reasons I was interested in embedding Go code in a Ruby environment.

For those who do not know how shared libraries operate, they work in a similar way as DLLs in Windows. However, they have a native code with a direct interface to the C compiler.

Note Windows uses the DLL system, and in this case, this does not necessarily have to be in native code.

One example is DLLs written in C#, which runs on a virtual machine. Because I do not use windows, I ended up not testing if it is poss

Download docker-compose.yml to dir named sentry
Change SENTRY_SECRET_KEY to random 32 char string
Run docker-compose up -d
Run docker-compose exec sentry sentry upgrade to setup database and create admin user
(Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
Run docker-compose restart sentry
Sentry is now running on public port 9000
