centos – Centos8: Discs IDs broken after moving from VMware ESXi to HyperV

I have moved Centos8 VM from ESXi to the HyperV 2019 core (hdd only)
It seems the disks or partitions IDs are broken so it’s not staring up properly using default/first Grub menu option.

But it runs with last (rescue) option.

How can I rebuild “rescue” so default grub menu option will run?

Email Format Broken When Sending Emails in Gmail

I recently noticed that emails sent out of my school gmail account were not utilizing the full space for text. For some reason, the body of the email breaks every 10 or so words to a new line. Attached is an example of this:enter image description here

unreal 4 – Selecting/Hiding is broken for Perspective but works for Orphographics views. Why?

I’m learning Unreal4. Got a problem with selecting, focusing and hiding objects.

  1. Focusing Issue: Focusing have to be done separatly for perspective view and ortho view. Why it is so?

Example: If I select an object in perspective view and focus on it (key F) everything works only for perspective view, but at the same time in ortho view no focusing occurs. So inorder to focus on the object in the ortho plales too I have repeat the whole process again: find object in orpho plane, select it, click F and only then focusing happens in all ortho view planes.

  1. In perspective view “Show only selected” does not work, but works in ortho views
  2. The same issue with “Show all actors”.

Please, I need help. Thnaks.

P.S. Damn, it looks like I’m in some kind of a mode (for the lack of a better word). I mean in my clicking around, i’ve clicked ON some mode and now this selectionhiding thing works buggy…

Is `DSolve` broken?

For real $x$ consider the trivial equation
$$|y'(x)|=-e^x.$$
Since the left side is always positive and the right always negative, there is no solution.
Let’s try

DSolve(Abs(y'(x))==-Exp(x), y, x, Assumptions-> {x (Element) Reals})

and

DSolve(Sqrt(y'(x)^2)==-Exp(x), y, x, Assumptions-> {x (Element) Reals}) 

both giving the wrong result

{{y->Function({x},-E^x+Subscript((ConstantC), 1))},{y->Function({x},E^x+Subscript((ConstantC), 1))}} 

At least

DSolve(RealAbs(y'(x))==-Exp(x), y, x, Assumptions-> {x (Element) Reals}) 

does return {}.

Is this a bug or a feature?

Note that this is just one example. In any case when the equation is $f(y'(x))=…$ and $f$ contains square root or absolute value the results are wrong.

Right now, I just used sudo apt-get remove --purge nvidia-* -y So now I am left with no drivers at all. Any recommandations to get my GPU driver?
