NArgMin with Root functions

I’m trying to minimize an error function sumt to find some parameters S, s0, si :

Ris[S_?NumericQ, s0_?NumericQ, si_?NumericQ, so_?NumericQ, R_?NumericQ] =   RR /. Solve[((8 RR*S ((2 RR^2)/R^3 - s0))/R^3 +         8 \[Pi] RR si + (8 \[Pi] RR^2 so)/(R^3 + RR^3)^(        1/3)) == 0, RR][[4]] ri = {54, 55, 62, 66, 62, 66, 71, 75, 77, 79, 94, 89, 99, 113, 124,    123, 140, 157, 163, 176} re = {72, 74, 82, 83, 90, 97, 104, 113, 115, 126, 136, 143, 158, 171,    185, 192, 218, 226, 246, 270} Rdata = (re^3 - ri^3)^(1/3); tableerror =    Table[(Ris[10^S, s0, si, 1, Rdata[[i]]] -        rayoninterne[[i]])^2, {i, 1, Length[rayoninterne]}]; sumt[S_?NumericQ, s0_?NumericQ, si_?NumericQ] =    Total[tableerror]; NArgMin[{sumt[S, s0, si],    8 < S < 11 && 0.001 < s0 < 0.1 && 0.001 < si < 10}, {S, s0, si}] 

But this doesn’t work and I suspect that it is because the Root function in my Ris function. Is it the issue ? And how could I fix this ?

Unity – Root Motion Physic Material Issue

I have a slope with an "icy" physic material with 0 static and dynamic friction. I also have this same physic material set to my model’s capsule collider. The model’s rigid body has a mass of 10.

When the penguin preforms its root motion belly slide on the ice, I expect the physics engine to do its work and see the penguin slide down the slope. However, I instead see a slow, sort of inching down the slope as shown in linked video. When I turn root motion off, the sliding works as expected.

What is going on here? What about root motion would be causing this?

I have tried a slew of root transform position baking options (including y) and it seems none make any difference.

Any insight is much appreciated! Thanks.

Can we implement hreflang on root domain for one country and on sub-folder for another country?

Is it possible for 2 countries, we can implement hreflang tags on root domain and a sub-folder, for example for US hreflang on and for Italy can we do it like this?

I have added both urls in Google search console & submitted separate sitemaps, but Google is counting all pages (including sub-folders) for the main domain, so I am thinking that Google is considering main domain (root domain) as a whole website not a country specific as per hreflang.

If you know about this or have similar experience, then Appreciate your help! Thanks, Adil

Is there any root motion workflow that doesn’t require feet adjustments on frame by frame basis (Blender)?

Ive been searching for an hour or so, but wasn’t able to find an specific answer about this problem. I need to make animations moving the character’s root around for my game, so in place animations aren’t a possibility. For now, I moved just the root bone (whole character) in straight line to ensure it has the speed movement I need in game, but now I need to start to add the actual feet movement to this animation movement. It happens that both feet follow the root movement (obviously), even when one of them should be planted. I did find some information pieces around the web, but nothing fixed this problem for me. I really need a best workflow for this, cause fixing the feet position on frame by frame basis seems to be a very bad, not to mention time consuming, way to do things.

I even considered unparent the feet from the root, but I’m positive this will cause problems in Unity as I need to use Humanoid rig there, which presupposes that the whole bone chain is connected to a single root.

I’m using Blender 2.8 and my rig was genereted by Makehuman, with the optimized for game engines option checked.

Does anynone knows a good workflow for this case? Maybe I missed something in my previous searches, cause this doesn’t seems to be a big deal at all, it must have a better way to this..

Thanks in advance for any insights.

What are the security implications of adding an Intermediate Certificate into the Trusted Root Store in Windows?

I have 2 certificates (one root and one intermediate).

In Windows OS, the Root certificate is in the trusted root store (for current user). The other intermediate certificate (signed by the root CA), is to be found (under current user also) under the Intermediate CA store.

I am using SSL verification in one of my client applications (Kafka Confluent) and realized the client only enumerates certificates in the root store. Therefore SSL handshake fails (the intermediate CA is needed).

One solution is to import that certificate into the Trusted Root Certificate Authorities. With that solution, SSL verification at client works. However, is there any concern in doing so?

From security point of view does it make a difference if the intermediate CA exists in the Root store vs the Intermediate store on Windows?

UPDATE If more context is needed as to what exactly I am facing you can check the issue here

Why would a certificate authority have multiple root certificates?

When I look at the trusted certificates in my browser, I see that many certificate authorities have multiple root certificates associated with them. For example, org-Amazon has Amazon Root CA 1, Amazon Root CA 2, Amazon Root CA 3, and Amazon Root CA 4.

How do the purposes of these four certificates differ?

I also see that some CAs have root certificates of different "tiers", such as gold, silver, and platinum. What’s the deal with these? I imagine there are price differences associated with the different tiers, but what extra service could they be offering?
