If you take a look at the difference:

Use the following pattern which will cater to both, the three-letter abbreviated month names as well as the full month names:

but for some reason, the precision of my integrator maxes out at 16 significant digits.

At a minimum, use more correct values of long double initialization with long double quotients rather than double quotients.

We can use str_remove to remove the _ followed by one or more characters that are not a _ ([^_]+$) at the end ($) of the string and specify a regex lookaround ((?<=[0-9])) so that it matches the _ that follows a digit

I have personally never used RestSharp, however here is the documentation related to specifying the request body of the RestRequest object: https://restsharp.dev/usage/parameters.html#request-body

Specifically, the documentation suggests using the AddJsonBody method: https://restsharp.dev/usage/parameters.html#addjsonbody

Here is an example using your desired body content:

Another way is create a map of key, value pair. Find DemoName in all keys. If DemoName is key then execute value function.

Why do you use the formatter? You already have a LocalDateTime

There are four privilege levels (called rings) in 386 protected mode as well as in 286: ring 0 has the highest privilege (operating system), rings 1 and 2 are not widely used, and ring 3 has the lowest privilege (user application). Rings 0-2 are called "Supervisor", while ring 3 is called "User".

The current privilege level (CPL) is determined by the address of the instruction you are executing, according to the Descriptor Privilege Level (DPL) of the code segment. For more information about the current privilege level, see CPL vs. DPL vs. RPL.

The bit that you are referring to is the following. It is a bit 2 in a 32-bit Page-Directory Entry (PDE) that maps a 4MB page (or of a 32-bit PDE that references a page table). This bit is called "User/Supervisor" (U/S). The value of "0" in this bit means that the user-mode accesses are not allowed to the 4MB region controlled by this entry. This does not mean that there are, as you wrote, just "2 privilege levels (supervisor and user)". The "supervisor" level still consists of three rings. This comprises, together with the user ring, four rings in total.

See section 4.6 of Intel 64 and IA-32 Architectures Software Developer’s Manual, Volume 3A: System Programming Guide, Part 1:

Every access to a linear address is either a supervisor-mode access or a user-mode access. For all instruction fetches and most data accesses, this distinction is determined by the current privilege level (CPL): accesses made while CPL < 3 are supervisor-mode accesses, while accesses made while CPL = 3 are user-mode accesses.

Therefore, CPL can be 0, 1, 2 and 3, effectively having all 4 rings.

Please find more information on the U/S flag from the manual above mentioned:

Some operations implicitly access system data structures with linear addresses [...] called implicit supervisor-mode accesses regardless of CPL. Other accesses made while CPL < 3 are called explicit supervisor-mode accesses. Access rights are also controlled by the mode of a linear address as specified by the paging-structure entries controlling the translation of the linear address. If the U/S flag (bit 2) is 0 in at least one of the paging-structure entries, the address is a supervisor-mode address. Otherwise, the address is a user-mode address.

P.S. My answer does not address the issue why there isn't the same memory protection between ring 1 and ring 0 as it is between ring 3 and rings 0/1/2, so the rings 1 and 2 are unusable if a page-table entry can't distinguish them from ring 0. See the reply by Peter Cordes that addresses this issue.

Edit: Java has a rough support for Julian day number. It counts the days correctly. It doesn’t begin a new day at noon as the Julian day defines, and it doesn’t support fraction of day. We can still use the support and make the proper adjustment ourselves.

As far as I can see the following methods make a consistent conversion forth and back and agree with the Julian day number that you got from toJulian() in JavaScript.
