Designing a teaching aid that works like GParted

…that updates regularly as with systems software. To teach user how to quickly and accurately set up partitions and install multiple operating systems — preferably Linux distros. Works just like the real thing but does not affect the actual hard drive, only the fantasy hard drive. Guides automatically, corrects mishits and gives prompts and hints to user / player until multi-booting becomes second nature. Is there such a beast, an / or can somebody up here design this? I’ve watched several videos and have tried to wade through a few pages of the stuff, but it won’t sink in. I really want to dual boot with Linux w/o messing anything up.

Designing distributed authentication/authorisation system

I’m trying to design a system that has the following elements:

  1. the main backend REST API (currently one, probably multiple in the future)
  2. front-channel client(s) — JS-based single-page app(s)
  3. back-channel client(s) as libraries, CLI apps etc
  4. a central RBAC API defining roles, groups and permissions
  5. a separate identity and authentication service that supports OIDC and SAML

All of the elements described above, except for the last one, are developed and deployed by my team, and all of them including the last one belong to the same application. Any external users we might have in the future will still be identified through the identity service.

I would appreciate any pointers to how to implement the authentication of the users of 2 and (especially) 3, as well as authorisation of users according to the RBAC constraints. My thought was to use OAuth2 and transfer the permissions using the Access Token, but I’m not sure if that is the right approach and, even if it is, how to specifically implement it.

I know this question is a bit vague, and I’m mainly looking for an advice on best practices and any previous experience, to avoid reinventing the wheel. Thank you!

I want write a simple wysiwyg editor(Something like UI designer in Visual Studio) in my web App to design Graphic interface which will be displayed in my dedicated hardware. I want have output with html to render result on my hardware. First i tried Fabric JS and Canvas – But this solution didnt gave me at “output” except svg….

With control i would like share to user: * Shapes(Traingle, Rectangle etc) * Predefined buttons * Embed image * Other custom controls(For example angular components)

How to make use of opponent policy on designing ours in multi-agent learning

I’m currently working on a multi-agent reinforcement learning. The setting is a cooperative multi-agent system with a stationary assumption on the opponent policy. Suppose I have the model of the opponent policy $ \rho(\cdot|s_t)$ , where $ s_t$ denotes the environment state at time $ t$ . I’m currently wondering how to actually make use of it to design our controllable agent policy $ \pi(\cdot|s_t)$ ?

Intuitively, I think the form of the policy should be like $ \pi(\cdot|s_t,\rho(\cdot|s_t))$ . Yet, I don’t have any idea to parameterize the expression, i.e. make it as a functional form $ \pi(\cdot|s_t,\rho(\cdot|s_t)) = f(s_t,\rho(\cdot|s_t))$ . Does anyone have some clue with a sound/best practice parameterization? Any thought would be appreciated.
