linux – Memcache extension unavailable in PHP 8?

I am setting up a new server, and when enabling some required PHP extensions using WHM EasyApache, I couldn’t find the Memcache (not memcacheD) extension, I did a quick search and found here that it is unavailable.

But here it says that the version 8.0 dependencies are PHP v8 or newer.

I guess my question is, if I install it manually, will it work well? If so, how do I install it?

file extension – What does a URL ending in / serve?

I have noticed recently that many websites have urls ending in /. For example if I wanted to visit an about page on a website, I would have been used to seeing, however now I see
My question is, what is the location and file name of the page being served?

To expand, I thought that would serve index.html located in a directory called about, but if I change the address of the website to, that page doesn’t exist.

What page is being served and how is this being implemented?

microsoft office – Right Click + New XLSX Workbook Results In “Excel cannot open the file because the file format or extension is not valid.”

Lately I have been having an issue that seems to have happened quite out of the blue where if I go into a folder from File Explorer to create a new .xlsx workbook using a right-click I will create a 0kb file and then I receive an error message that says:

Excel cannot open the file 'name.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.

Oddly enough, if I open Excel directly and work in a .xlsx file and save it, then I can reopen that file later on. So it seems like I have all the sudden lost the functionality of being able to right-click open a new .xlsx document. If I try to do this exact same thing with a .docx file though, everything works as expected.

What have I done so far?

  • I have opened Excel and have gone properties -> security and made sure permissions are set to Full Control.

  • I have checked that the file format that I am opening is indeed .xlsx and not something else.

Unfortunately most of what I have tried to find online does not seem to be helping, so I needed something a bit more interactive.

algebraic geometry – Degree of vector bundle under extension of scalars.

The degree of a bundle, of course, does not change under extensions of scalars and semi-stability is preserved, because the Harder–Narasimhan filtration is canonical, hence Galois-invariant, hence descends from the algebraic closure of the base field.

$earnRules = $block->getDisplayEarnRules();
$spendRules = $block->getDisplaySpendRules();

google calendar – How to authorize Zoom for G Suite extension

I use G Suite for my personal email. I installed the Zoom for GSuite extension so that I can add Zoom video conferencing to Google Calendar events.

When I select Zoom as a conference option, I’m prompted to log in to my Zoom account, and then I’m given this error screen (as you can see I already clicked the request button):
enter image description here

I am the admin for my G Suite organization, and I don’t know how to grant this pre-approval. I’ve poked around the G Suite admin panel a lot but haven’t had any luck.
