1. Any tool that reduces the privileges of your application code, such as Osgood or Deno, is doing so because application code cannot necessarily be trusted, since you're pulling in external dependencies that can have vulnerabilities or malicious code, and even one's own code may have unknown vulnerabilities that may cause unexpected IO behaviour to happen.
2. The policies you can set with Osgood are defined in a JavaScript file that is run separately from your application code (i.e. the worker files), and it only runs once to build up the policy data structures in native code. This V8 Isolate is then discarded. This means that application code cannot modify its own policies.
In my case, I was denied entry due to a paperwork error in Toronto and so had to stay at a hotel to catch a flight the next day. It would have been nice had everything been arranged and applied for ahead of time.
Of course, it might not be the case that Canada Post data is under Crown Copyright, since it's a Crown corporation and not a government department. IANAL.
The whole world has postal codes. Some are simpler than others. It would be nice to see an API like this one that supported more than just one country.
I've used this. It only makes sense for very small images. You basically have to lower your font size down to unreadable levels in order to even see an image of any reasonable size, much less edit it.
I love vim and like to keep as much of my development environment inside it as possible, but it's a text editor.
