Jack Audio Service and Surround Audio Systems

I use Ubuntu Studio 19.04.

I’ve been experimented with Jack Audio Service and I have a doubt about the Audio Connection Panel:

Whatever the configuration I use, I don’t have any reference to my physical 7.1 surround sound card, which is an Intel Corporation 6 Series/C200 Series Chipset Family HDA_Intel, included inside the H61M-P31/W8 (MS-7788) Motherboard.

I just get this:

My Jack Audio Connections Panel

As you can see, there is not any reference to the front, rear or side audio channels.

So… What’s wrong here?

Or… What had I missed to do?

Is there a best “all-in-one” tool for UX design, prototyping, handoff, project management and design systems?

I work at a company that operates as e-commerce, and we use Shopify as our platform. I’m a product designer at said company, in a two-person team that includes myself and my boss, and we rarely work on the same designs at the same time.

Currently, our tool kit includes:

  • Sketch: Used to build & update a working style guide & component library, as well as design wireframes and hi-fidelity mocks
  • Zeplin: 1) Dev Handoff, i.e. visual specs, assets, etc. 2) Sharing mocks & commenting 3) To house projects 4) To house our style guide/component library.
  • InVision Cloud: We use this for its basic prototyping tools and to share prototypes with stakeholders or user test participants. We use Favro for tickets & project management (not great), google docs for documents and decks

However, we’re running into a myriad of issues. I’ll outline some of the primary ones below, in order of most to least important.

  1. Design System Manager: Overall design system portal that does style guides & component libraries, rules & definitions, and also does version control to manage updates (that’s really tough to keep track of now)
  2. Advanced prototyping: Ability to add more advanced things like animations, component states, interactive elements, conditions/logic, etc. to better present functionality to developers/stakeholders. Overall stronger developer handoff with more advanced features that allow designers to design more accurately to code and gives devs more to work with (Seems FramerX is leading this charge: https://www.framer.com/development)
  3. Responsive design: Setting component constraints and responsive resize to design faster and more strategically
  4. Project management: Ability to track project status, assign tasks to team members, nest various prototypes & design files within one project, and has version control
  5. Annotations & documentation – Seamless, easy way to create annotations for specifications & documentation for developer handoff (UXpin seems to be leading this charge https://www.uxpin.com/studio/user-guide/the-uxpin-editor/)
  6. User Flow/Site Map generator – would be amazing to have a tool that generates these vs. having to manually do them (OverFlow seems to do this)

Obviously one tool won’t have EVERYTHING, but I’m trying to wrap my brain around all of the tools out there and which tool, or small collection of tools, make the most sense for my team. Any advice?

Key management for builds for embedded systems

Our medical device has embedded processors and a USB port used for firmware updates and logfile transfers. The usual USB viruses are not a concern (no mechanism to load or execute them, wouldn’t run in our unique environment). However a secure upgrade method is required by a regulatory agency, in case of malicious attack by someone with a copy of the source code, build environment and schematics.

In learning about security, our current concept is to use signing and encryption for upgrades and to embed the public key. Then we have to keep the private key private for the product lifetime, hopefully on the order of twenty years.

Is there a standard way to do that? Keep it on a secure build server?

How do I build Multiple Defenses/Security Systems for the same Heaquarters?

taking a slog through Mutants and Masterminds 3e again. This time, I’m working on a character with a county-sized headquarters (Awesome headquarters with Grounds feature). In his backstory, the character had acquired himself several plots of land in Nebraska and managed to earn District status for them through shenanigans and malicious compliance. All the complications from this are fairly straight-forward, but I’m drawing a blank as far as making the Security and Defenses flow with that concept.

See, the Grounds feature states that Defense Systems and Security Systems extend through the area surrounding your Headquarters, and the Defense System feature states that it can be any attack effect with a cost no more than double the HQ rank. Keeping in mind that this headquarters is a populated county with its own problems, I don’t want to have people blasted with space lasers for loitering, nor do I want a Mall Cop to smack a hover-tank with a nightstick. So, mostly for fluff reasons, I want to have a handful of different Defense and Security systems in my headquarters that are tooled to different potential situations; how do I do this?

Resetting Vector clocks in distributed systems

I understand that vector clocks are preferred over lamport clocks because sometimes lamport clocks cannot account for the casuality and we use extra space to store the timestamps in the vector clocks. What i dont understand is about the resetting of the vector clocks. Why do the vector clocks overflow and how the resetting is done in such scenario?

What does it mean that the “clock is present” in Cyber Physical Systems domain?

I am doing an assignment in designing a very simple CPS and in one of the problem, I was asked to design an event-triggered combinational component. In the context, the system will compare inputs during rounds in which clock is present.

I cannot make it clear what this clock being present exactly means. Can anyone give me a clue?

Can a virus be spread to AI systems via looking at image/ Video?

Scenario: AI advanced until we use it on spaceships to see what is outside. Then the AI system would have to process whatever image they see from the stars, or videos if we add in time.

In our PC, a jpeg file can contain virus, but we need to click on it for the virus to act. For the AI, the clicking seems to be default yes, or else it is basically blind.

If there are Hyper advanced AI out there who wishes to spread virus to other possible AI to either destroy or assimilate them, might they be sending light signals which can become a virus if processed by our image processing AI?

Inclusive notification scheme incorporated into design systems

It seems like the standard RED, YELLOW, GREEN and BLUE colours are used in notification schemes/styles in the most popular development frameworks like Material.io and Bootstrap.

Of course, colours shouldn’t be used by itself as a UI design element, but the standardization of the RED and GREEN combination in a colour palette reduces the effectiveness of other design elements to distinguish between different statuses in the notification scheme/style.

Are there examples of design systems or development frameworks where the notification scheme/style takes into consideration of the common issues:

  • Red and green colour blindness (and other forms of colour blindness)
  • A low contrast (i.e. bright or feint) yellow
  • simple and clear iconography to complement the notification colour scheme
