None of the above checkbox in Google Forms

I would like to create a multiple choice checkbox question in Google forms with a ‘None of the above’ option and validate that if that option is selected none of the other options is selected.

eg Choose your favourite fruits _ Apple _ Pear _ Orange _ Banana _ None of the above

I cant see how to perform that sort of validation using the built in validation options

Is there a way of performing such validation at data entry time?

On boot: Core/Package temperature above threshold, cpu clock throttled

I a new Linux user and this is my second question. Most of the time, I try to find solutions on the internet by myself but when I’m really stuck, I must ask my question here so I will try to give you as much needed information as needed so feel free to ask. I also want to thank this community. A lot of you respond quite quickly and try to help us as much as possible and this is just amazing to see.

Anyway, here is my problem:

I just got a new computer (Lenovo Thinkpad E590 i7-8565) and I successfully installed Ubuntu 18.04 LTS next to Windows 10. So, I have both OS available when I boot and I made a third NTFS partition where I can store my files which can be accessed on Linux and on Windows 10.

I had an issue that I solved a few days ago where my motherboard made a very hard and long beep. The beep started when I did boot my computer and ended when I left GRUB. This was an issue with the kernel (I don’t really understand what this is yet) that I had to update. So now, my kernel is 5.0.7-generic (I think, I would like to know where you can see the current version).

But now, sometimes, not always, when I boot on Ubuntu, I got this showing up: (I know I’m supposed to post those error messages right here and not on this picture but I cannot copy them while booting and I don’t know where to find them after that.)

enter image description here

I got stuck between this screen and the Ubuntu loading screen.

My only option is to press the power button and to restart my computer again. After 2 or 3 tries, those errors don’t show up I can boot normally.

I checked the temperature of my CPU and everything seems to by normal.

Output for $ sensors:

thinkpad-isa-0000 Adapter: ISA adapter fan1:           0 RPM  coretemp-isa-0000 Adapter: ISA adapter Package id 0:  +45.0°C  (high = +100.0°C, crit = +100.0°C) Core 0:        +43.0°C  (high = +100.0°C, crit = +100.0°C) Core 1:        +44.0°C  (high = +100.0°C, crit = +100.0°C) Core 2:        +45.0°C  (high = +100.0°C, crit = +100.0°C) Core 3:        +44.0°C  (high = +100.0°C, crit = +100.0°C) 

I’m tried several solutions I have found on the internet but no one fixed it.

I hope to find a fix here.

Thank you very much in advance for your help.

Does the Star card from the Deck of Many Things increase your ability score above 20?

Inspired by this question regarding the Star card from the Deck of Many Things and an Ioun Stone:

The Star card reads:

Increase one of your ability scores by 2. The score can exceed 20 but can’t exceed 24.

However, this does not say that it increases your cap/max for that ability score. So assuming your ability sstarted at 20, does this mean that, RAW, it would increase to 22, and then immediately revert back to a score of twenty because your cap is still just 20? Alternatively, perhaps the Star card increases your cap as a whole to 24?

Dynamic link does not work on iOS version 12 and above – Flutter

I am using Google Dynamic Links for Firebase plugin to implement dynamic link.

I done with the all steps which required to implement deep link.

Everything works fine below iOS version 12 but when updated my iPad to latest iOS version 12.2. It does redirect and open my app. when i do page refresh in the safari it some times open the app.

Future<void> _retrieveDynamicLink() async {     final PendingDynamicLinkData data = await FirebaseDynamicLinks.instance.retrieveDynamicLink();     final Uri deepLink = data?.link;      if (deepLink != null) {       Navigator.pushNamed(context, deepLink.path); // deeplink.path == '/helloworld'     }   } 

Any help will be appreciated. Thanks in advance

Integral of a Function of a Convex Combination bounded above by the integral over the entire ball

I am working on this homework problem, and I went to the professor for help but I don’t think his solution is correct (it seems to assume that $ W^{1,p} \cap L^\infty$ functions are uniformly continuous, which to my knowledge they are not). So I tried to prove the result a different way using the Mean Value Theorem. This leads to my question: supposing we know nothing about the value of $ c$ other than it is between $ 0$ and $ 1$ , can I find a bound independent of $ c$ such that \begin{align*} \int_{B(a,\delta)} f(cx+(1-c)y) dy \leq C\int_{B(b,\delta)} f(u) du, \end{align*} with $ f$ being an $ L^p$ function, and $ b$ may or may not be different from $ a$ . I originally thought we could just say $ C=1$ , but then I realized that for a fixed $ x$ the map $ y \mapsto cx+(1-c)y$ is not necessarily one-to-one if we allow $ c$ to be chosen freely (again thinking Mean Value Theorem; changing $ y$ will change $ c$ ). Furthermore, I was thinking of looking at a change of variables, but then this gives you a factor of $ \frac{1}{1-c}^n$ , which (if $ c$ is “unknown” as I am assuming) blows up as $ c$ gets close to 1.

Any help/hints would be greatly appreciated.
