Perhaps I should have been more explicit. "Practitioners of linear algebra...." i.e. those who deal in vectors, matrices, tensors and their ilk.
Yes, Pascal arrays were nice. A large C project I worked on, someone wrote a bunch of macros to try and emulate that. Very clunky; modern C++ could do a much better job, I'm sure.
Oh, and here, floor numbering includes an implicit zero. A local example goes 2 1 G B1 B2
A lot of (old) instruction sets included features to "help" compilers. One of my favourites was "back axle" BXLE in the IBM 360 and derivatives. Intended to be the bottom of a FORTRAN do-loop, it used 3 consecutive registers to hold the running value, increment and limit. Do the incrementing, and branch if still looping (less or equal to limit). None of the FORTRAN compilers I saw ever used it though!

perhaps off topic, but I suddenly thought about this mnemonic from vector analysis
"curl of a curl equals to a gradient of divergence minus Laplacian" 
|
|
|
|

That's not a mnemonic, that's a book 
It does not solve my Problem, but it answers my question

But I do remember the meme for sin, cos, and tan math my 10th grade teacher taught us:
Oscar Had A Heap Of Apples and Sally Counted Them
O/H = S(in)
A/H = C(os)
O/A = T(an)

I like it and I'm sure it is a "brain burner" (1:1 german english translation) at least for me.
Thanks.

Me and the wife are a bit baffled, and trying to work out what is going on.
This morning, she got a missed call from me on her mobile (android). Problem is at the time stamp, my mobile was powered off, in my backpack, sat in my office on the platform, a room which has no mobile signal. She is in Cyprus, I am in Qatar (well actually halfway between Saudi and Iran in Qatari waters north east of Qatar.)
We do have sporadic mobile reception from Qatar mobile operator Ooredoo, but do not know where this is provided from. Whether it is a vessel/rig etc. with a mobile station. Certainly doubt it is reached from the mainland as it full strength signal on my device.
Could this be a spoofing? or has someone cloned my sim or IMEI or can there be some other explanation.
Has anyone any idea how we can determine what the actually elephant has gone on?

I was in my office awake, just finished the morning calls with the onshore office!

Contact your mobile carrier? They will have access to their DB.

It could be spoofing (more likely) or a cloned SIM. Regardless, my concern would be that someone knows that calls are regularly made from your number to your wife's number. They might try to convince her, for example, that they've kidnapped you, the proof being that the call is coming from your mobile, and that she needs to send a ransom payment to wherever.

I guess since the cat has already left the bag you might as well know about SimJacker. The carrier Ooredoo is on the list of companies affected.
Natural Selection obviously will eliminate these vulnerable SIM cards.

Spoofing is really bad where I am. I've heard of people getting phone calls from their OWN phone number. A lot of them at the very least have very familiar area codes or prefix to try to get you to answer it.

Someone asked me if I could give any advice about database clustering with PostgreSQL preferably on a Windows platform
It turned out hard to find a solution that was not Linux based, but I found some and added them here: database-cluster-managers[^]
Now I wonder if anybody has ever used something like e.g. SymmetricDS and how it will perform with lots of SQL write and read operations.

We use Citus, but on Linux. Not sure if it's what you are looking for, but it's worth a look.

Thanks, that's a well known name, it was even acquired by Microsoft so maybe a Windows version is in the pipeline

Windows - settings - ease of access - automatically hide scrollbars in Windows - OFF !!!
Finally, what a joy …

Thank you! Aahhhhhh.....

This "ease of access" was bugging me (and everyone I guess) for some time  , but only recently I think this solution arrived, MSFT deserves good points for correcting this ...

Microsoft decided that "knowing there was more if you scroll" wasn't important and auto hide the scrollbars in UWP apps by default until you hover the mouse over where they might be if there is any more to see. Stupid UI design, a retrograde step in usability.
