domain name system – Static website I am hosting cannot be reached and the server IP cannot be found

I recently used Google Domains to register a domain and have connected it to Google Cloud Console to manage a static website. I followed the Google Codelabs guide to set it up and faced no issues. However, when refreshing my website, it still doesn’t load and my browser (Chrome) gives me the following error message:

This site can’t be reached’s server IP address could not be found.”

As well, going to gives me another error message:

Your connection is not private

Attackers might be trying to steal your information from (for example, passwords, messages, or credit cards).


…Which is confusing, because I was under the impression that a .dev domain suffix gives SSL certification by default.

However, in my Google Domains settings, the website content appears as it should in the minimized preview that exists in both the Domain Overview panel and Website panel. It has been over 48 hours, so it should have updated by now if it were just a delay issue.

For reference, this is what my Custom resource records look like, and these are my bucket details in Google Cloud Console. If it matters, I am also using a Mac.

Any help is much appreciated!

c# – System Design – ASP.Net MVC Preparations

I’m about to start an mvc project with Repositorty-Service pattern and I’m first gathering information. Therefore I’ve got few questions that I need clarification before I start implementing.

In my company, most of the mvc projects developed by senior developers possess common features such as :

So my questions are :

1) Do I always need a caching mechanism and logging and Security(Encryption – AES…) in an mvc app?

2) When do I need them? I mean in what situation do I need caching and logging and Security(Encryption)? please give me detailed answer for each for clarification.

3) Is it fine/professional to use in a real-world project, the default ASP.Net MVC authentication code that gets generated when you create a new app? as I’m building a quite big (not very big) web app with Repository-Service pattern and I just want to reuse the default MS ASP.Net authentication (to save me time) instead of writing a new one.

4) Do I need to use SQL Server or MongoDB as database? I know that MongoDB is best suited for scalability but I don’t want to use a library which I’ll be forced to dig in to its library DLL and modify some code in order to make it work, as I don’t want to waste my time as the project is timed.

rooting – how to upgrade operating system of micromax E311 device for a novice user

I have Micromax E311 phone.

For some reason the settings of phone have become unreachable. So on the display I see Setting icon with a mechanical gear on it but when I tap it then I get a pop up

Unfortunately, Settings has stopped.

I clicked Ok.

Then again the same message pops up within a fraction of second this keeps happening then I restart the phone somehow and if I touch settings then same thing happens. If I don’t touch the setting’s icon, there is no problem I can keep using the phone.

So I am not sure what is the OS in this phone. My guess is that it has been formatted to the factory settings, so it’s having Android 4.4.2. I read many tutorials about rooting the phone and installing custom ROM on it. Like

After rooting an Android phone, you can switch the operating system
ROM whenever you want. The rooting process removes the preinstalled
operating system on the Android phone, replacing it with a rooted
Android OS.

How To Install Custom ROM on Android

For my device flash rom

What I am confused with is to upgrade my device OS to android 10, first I should replace the ROM and then do “something” as mentioned on lot of forums or what exactly I should to to upgrade the OS of my phone.
I am very confused with all the tutorials available on internet.
I want to know simple steps in bullet points like

  • Step 1 change ROM
  • Step 2 change this
  • Step 3 change that
  • Step 4 boot phone.

Meaning such a guideline will help me when I read tutorials, and I was getting confused with them.I am not sure if with android 4 OS I can directly upgrade to some thing like android 9 or so.

what is system centered design?

I can’t understand the idea or concept of system centered design.

I have tried surfing the internet for it but it mostly directs me to user-centered design.

8 – Layouts using the grid system

How can I lay out blocks or paragraphs using Bootstrap’s grid system? I found this seven-year-old answer and am hoping things have evolved since then, and if so would like to know how.

My best stab at cobbling together something at this point is to use Paragraphs for the content and use the Block Class module to assign the desired Bootstrap class to each paragraph type. Is there a more obvious and cleaner solution to the problem in Drupal 8?

dynamic – How to plot the stable and unstable manifolds of a hyperbolic fixed point of a nonlinear system of a map?

I would like to plot the stable and unstable manifold of the Hénon map x_{n+1} = 1 – a*x_n^2 + by_n, y_{n+1} = x_n. I believe that iterate the inverse map i would get the stable curve, and for the unstable i need to choose an large number of initial conditions inside the neighborhood of the saddle point along the unstable direction and then iterate the map for a few times, but i do not know how to do this things.

keyboard – how to disable system autocorrect?

Gboard has a toggle to disable/enable spellcheck completely, but using 3rd party keyboards such as AnySoftKeyboard shows this annoying red-underline and suggestion-box spellcheck and it cannot be disabled. the spellcheck is actually part of the Android system, not part of AnySoftKeyboard.

how can i disable spellcheck for the whole system
how can a dev implement a toggle to disable the spellcheck like Gboard does?
