Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

The Ruby Way! (Fun)

Go to the output .apk directory:

cd /Users/patriciolopez/Repositories/almapp/uc-courses-mobile/platforms/android/build/outputs/apk/

Put your release.keystore in that folder, if you don't have one (change ALIAS):

keytool -genkey -v -keystore release.keystore -alias ALIAS -keyalg RSA -keysize 2048 -validity 10000

Start GDB and execute the following commands:

catch syscall ptrace
commands 1
set ($eax) = 0
continue
end

Then, run the app and voilá! you can debug your program :)

// A vector type is composed as: `[vector size]T`.

// Odin has support for explicit and implicit polymorphic procedures and parametric types
// An explicit polymorphic procedure has the type passed as a parameter,
// while an implicit polymorphic procedure infers the type from the arguments

// a typical use-case for an explicit polymorphic procedure can be found in core/_preload.odin:
new  :: proc(T: type) -> ^T {
	ptr := cast(^T)alloc(size_of(T), align_of(T));
	ptr^ = T{};
	return ptr;
