Whats the best way to setup a webrtc based platform for video call, without worrying about different routers involved?

We are trying to setup a webrtc platform for some medical project which needs to do some video call. One end of the call is on the device terminal that is provided by us and the other end is a terminal owned by the client. Presently we are using only stun servers for the connection and we are having the following outputs :

  1. When both the terminals are connected via the same router, non portable, like dlink, buffalo, we get stable connection with no compromise on the video call quality.
  2. When both the terminals are connected via a single portable hotspot router, like Jio(India), we get stable connection with some break in between, but usually it connects back. Quality downgrade also happens some time.
  3. When both the terminals are connected to a mobile hotspot (mobile phone), stable connection with no quality compromise.
  4. When one of the terminals is a router and the other terminal is either a portable hotspot or a mobile hotspot, NO connection is established. The router is an asymmetric router. Although the router is connected via an optical to lan convertor router to connect to the internet.
  5. When one of the terminals is connected via a mobile hotspot and the other via a portable router, the connection breaks frequently, but reconnects most of the time. However, quality is often compromised.

We need help into figuring out what should we do to ensure connection stability. What can be done to create a connection in case of the fixed router at one or both terminals. (P.S.: we want to avoid using or setting up a TURN server)

Also, lastly, if there are no alternatives except to setup a TURN server. What should be the best approach to set it up to reduce the cost of providing the service. (Assume here, that we may setup all services by ourselves if required). Cost is the most important criteria, in setting the TURN server.

Thank you all in advance.

How to choose which Edge to apply when multiple stat pools are involved?

The special ability “Successive Attack” costs 2 points of Speed, and can be used after a successful attack to make another attack.

So it work like this: First attack. If enemy is down the PC can use Successive Attack and immediately make a second attack.

If the character used no Effort in the first attack, she can use the Speed Edge to reduce this cost.

But what if the PC used Bash, that cost 1 point of Might, in the first attack (or if she used one or more tier of Effort)? What if she used Might Edge to lower the expense on Might pool?

As a general rule, how does Edge works when multiple stat pools are involved? And how does it work if the PC uses special abilities that lead to further actions?

Attempting to understand shape and parametric equations involved.

This is a project I am taking on and I am in need of some direction.

The eventual application is engraving on the angled surface using CNC machines.

I do know the blue line does not change in radius as it moves around the axis and forms a helix. The difficulty I am having is understanding how to calculate the radius change as you move across the part horizontally (green line). I believe that forms a sprial of uniformly increasing radius (at least until the helix “resets”). Also, it is pertinent for me to know based on radius and arc length, the required change in theta with respect to centerline axis to accomplish desired distances.

So far I have researched Pappus’ conical spiral and the Archimedean spiral.

Once I understand how to approach this shape I believe I can apply the mathematics to it but I am have difficulty understanding exactly what this shape is.

Any help in the matter is greatly appreciated. Thank you, SML.

How involved should a PO be in Sales Meetings? [on hold]

How involved should a PO be in Sales Meetings?

The POs in my company seem incredibly overstretched. They do not have time to create AC for tickets or answer questions on project features and seem to be always in meetings and rely on developers to complete this part of their job. Often we get assigned tickets with a simple one sentence description.

I think it’s becuase they are often in different client meetings off site, which has left me wondering should they be so involved in the sales cycle?

I don’t think they can properly manage projects if they are. And I think it can also effect them from stopping scope creep, new features being added by client request without any time/money/resources allocated to them properly. When they’re in sales mode it’s harder to say no to a client, well it seems to be for them.

Has anyone else experienced this?

Hardware involved in Direct-connect (switchless) 2-node Storage Spaces Direct Cluster

For my department, I envision a two-node cluster of identical machines, running S2D.

I want to use Broadcom 57416 10GBASE-T Adapters (example description), because they support RDMA and run at the speed of the free infrastructure provided by my organization.

Microsoft says that I can connect a two-node setup directly.

Can you tell me what type of hardware and cable would be required for “direct-connect”?

Master Theorem Help – How to make the value of “b” greater than 1 as required by the Master Theorem? What math is involved?

I know how to identify the parts of the Master Theorem, and I know that it is a recurrence relation. I don’t understand how to make the “b” value greater than 1.

Please see the image. I know the math is easy, but I am not seeing it. Can someone help? enter image description here

Best message for “more posts” at the end of page (no pagination involved)

In my free time I’m building my site/blog from scratch using Jekyll (a template engine). Despite Jekyll has first-class support for pagination I want to avoid it so only the latest X posts are visible in my home page. If a user want to see older posts they should use the archive or make a search.

My question is: how can I invite users to do this?

This is my work in progress attempt:

no pagination

Any suggestion? Is there a better way? Thank you!

Risk involved with using SSH for CTF challenges?

I’m new to the INFOSEC scene and was intrigued at the concept of CTF challenges. I was hoping to get started with OverTheWire.org which requires you to SSH to their server to complete the challenges.

I am running Kali on a VMWare VM using bridged networking to my host device, which is on my home network.

Are there any security related concerns I should take into account before using SSH?

Thanks in advance, and please excuse my noobishness.
