I write my app without using Shell. So I created my own Window using IDialogService and opened in one of my modules. As far, as I am concerned, Region Manager is attached to Shell, but due to the fact I don't have it, region manager doesn't work when I try to navigate from one view to another.

I know that Region Navigation works fine with the shell (I tested it) and the same code stops working when I substitute the shell with IDialogService.

Here is what I have

I'm building a topological tree of sockets, NUMA nodes, caches, cores, and threads for any Intel or AMD system in C.

Building this hierarchy, I want to ensure hardware threads are grouped together appropriately so it's clear who precisely shares what. I've found that I can set a thread's affinity and then use the cpuid instruction to get a lot of the info I want, but not all.

If a package/socket has multiple NUMA nodes, how do I get an index of the NUMA node for the current hardware thread? If the NUMA node has multiple L3 caches, how do I get the index?

AMD has something for NUMA node ID in Fn8000_001E_ECX, but I can't find anything comparable for Intel. And nothing re: L3 index for either.

I'm developing an Android application with Embarcadero RAD Studio 10.2 to deploy on a Zebra TC25. I'm trying to activate the scanner by clicking a button on a screen. (Like pressing the yellow buttons on the sides of the pad)

I am reading [AMD64 Architecture Programmer's Manual Volume 1: Application Programming][1]. On page 47, which is about CMOVcc, it has a table which states:

On Intel processors, x87 trigonometric instructions such as FSIN have limited accuracy due to the use of a 66-bit approximation of pi even though the computation itself is otherwise accurate to the full 64-bit mantissa of an 80-bit extended-precision floating-point value. (Full accuracy for all valid inputs requires a 128-bit approximation of pi.) The omission in Intel's documentation was corrected after the issue was brought to their attention.

However, I cannot find similarly detailed information about the accuracy of AMD's implementation of x87 trigonometric instructions beyond this mention in the AMD64 Architecture Programmer's Manual, Volume 1:

6.4.5.1 Accuracy of Transcendental Results

x87 computations are carried out in double-extended-precision format, so that the transcendental functions provide results accurate to within one unit in the last place (ulp) for each of the floating-point data types.

Is AMD's implementation of x87 trigonometric instructions actually fully accurate to within one ULP in extended-precision format for all valid inputs, including a 128-bit or better approximation of pi? An answer that pertains to the Zen and Zen 2 architectures (Ryzen and EPYC) would be ideal.

In attempting to solve a separate issue, I switched to the Saxon XSLT processor and have been struggling to get the syntax of my code to work. The purpose of the code is to iterate through a list of HTML files, finding the first instance of any header in each page and converting it to an H1 (since we have to use H2s for our PDF output but need H1s for our HTML output).

I start with a batch file:
