Surely I haven’t won the lottery, but where’s the scam?

Some time ago I received the following message on my personal mobile phone number:

YOUR MOBILE NUMBER HAS WON 780,000EURO IN THE WORLD LOTTO END OF YEAR PROMO.FOR CLAIMS EMAIL(NAME/ADDRESS/PHONE) TO:Worldlotto@mediacombb.net

A WhoIs search for mediacombb.net returns the following:

enter image description here

I certainly did not take part in this “World Lotto”, so this being truthful is out of the question, and thus likely to be a scam.

How will the scammers benefit from me simply sending in my name, address and phone (which they already have), all of which they most likely have if they managed to get their hands on my personal phone number?

Not quite sure if it would be wise to go ahead with providing the requested info and update the question with further details as the case progresses.

Where’s my GRUB2 menu gone?

I’ve installed 4 different ‘Ubuntu’ flavours on 1 laptop. For demonstration and comparison. (L, K, Mint & X)

I would like to clean up the GRUB menu, put a BG in etc., but I can’t find it! There is, in each of the 4 installations/partitions a directory /etc/default/grub, but there’s nowhere the 10 lines of choice to be seen.

Where is it? And if I can extract it from the MBR, where should I do that? In the first or the last partition ?

Where’s the order item custom options labels in the REST API?

I’m trying to retrieve orders from the REST API in Magento Enterprise 2.3.1, and that’s easy enough with endpoints like /rest/default/V1/orders, but while I can see the values for custom options of the items in the order, I can’t see their labels. For example:

"product_option": {     "extension_attributes": {         "custom_options": [             {                 "option_id": "3730",                 "option_value": "Some text value."             },             {                 "option_id": "3731",                 "option_value": ""             }         ]     } } 

It’s great that I can see that for one of the custom options, the customer said “Some text value.”, but I’d really like to know what it was they were responding to. What I’d expect to see for each custom option is something like:

{     "option_id": "3728",     "option_label": "What's your favorite Star Trek ship?"     "option_value": "U.S.S. Excelsior" }  

So far, any time I can find a way to load an order via the REST API, it is returned this way, and I don’t see any other way to get the custom option label.

It’s hard to believe I’m the first person to come across this – am I just missing something obvious?

Where’s ATLAS installed on Ubuntu 18.04 Mate on ARM CPU?

I installed Atlas on Ubuntu 18.04 Mate using the command

sudo apt-get install libatlas-base-dev

I’m running this on an Odroid N2 (https://www.hardkernel.com/shop/odroid-n2-with-4gbyte-ram/), so it’s an ARM system.

While the command to install it works, I can’t find where it gets installed. I am trying to run GAMESS (https://www.msg.chem.iastate.edu/gamess/) and part of the configuration asks where I have installed ATLAS. In Ubuntu 16.04 Mate on an Odroid XU4, it was installed to /usr/lib/atlas-base, but I can’t find it there. Thanks in advance for any help.
