First of all, you are refering to the wrong documentation, yours is for UWP, not WPF.

• UWP UniformGrid
• WPF UniformGrid

The behavior should be the same, but it is not explicitly stated in the referenced documentation for WPF. However, there seems to be an issue that stems from setting VerticalAlignment to Center and is not related to the ItemsControl, it will be the same for an isolated UniformGrid.

Whenever the UniformGrid contains more than the maximum number of items it can display (Rows x Columns) and the VerticalAlignment is set to any other value than the default Stretch, all of the items are displayed regardless of the number of rows, but respecting the number of columns.

What you could do is remove the VerticalAlignment and try to compensate for it by aligning the ItemsControl in a way that it fits your original intent.

Hi try to install clipboard by using the command

1 FP operation per core clock cycle would be pathetic for a modern superscalar CPU. Your Skylake-derived CPU can actually do 2x 4-wide SIMD double-precision FMA operations per core per clock, and each FMA counts as two FLOPs, so theoretical max = 16 double-precision FLOPs per core clock, so 24 * 16 = 384 GFLOP/S. (Using vectors of 4 doubles, i.e. 256-bit wide AVX). See FLOPS per cycle for sandy-bridge and haswell SSE2/AVX/AVX2

There is a a function call inside the timed region, callq 403c0b <_Z12do_timed_runRKmRd+0x1eb> (as well as the __kmpc_end_serialized_parallel stuff).

There's no symbol associated with that call target, so I guess you didn't compile with debug info enabled. (That's separate from optimization level, e.g. gcc -g -O3 -march=native -fopenmp should run the same asm, just have more debug metadata.) Even a function invented by OpenMP should have a symbol name associated at some point.

As far as benchmark validity, a good litmus test is whether it scales reasonably with problem size. Unless you exceed L3 cache size or not with a smaller or larger problem, the time should change in some reasonable way. If not, then you'd worry about it optimizing away, or clock speed warm-up effects (Idiomatic way of performance evaluation? for that and more, like page-faults.)

1. Why are there non-conditional jumps in code (at 403ad3, 403b53, 403d78 and 403d8f)?

Once you're already in an if block, you unconditionally know the else block should not run, so you jmp over it instead of jcc (even if FLAGS were still set so you didn't have to test the condition again). Or you put one or the other block out-of-line (like at the end of the function, or before the entry point) and jcc to it, then it jmps back to after the other side. That allows the fast path to be contiguous with no taken branches.

1. Why are there 3 retq instances in the same function with only one return path (at 403c0a, 403ca4 and 403d26)?

Duplicate ret comes from "tail duplication" optimization, where multiple paths of execution that all return can just get their own ret instead of jumping to a ret. (And copies of any cleanup necessary, like restoring regs and stack pointer.)

It's defined in https://github.com/rails/rails/blob/f95c0b7e96eb36bc3efc0c5beffbb9e84ea664e4/activerecord/lib/rails/generators/active_record/model/templates/model.rb.tt

You should be able to add it there

Second, configure your options in https://github.com/rails/rails/blob/f95c0b7e96eb36bc3efc0c5beffbb9e84ea664e4/activerecord/lib/rails/generators/active_record/model/model_generator.rb

Try running the following commands on your local machine:

OpenStreetMap data consists of three basic elements: nodes, ways and relations. Your query searches only for nodes. Some schools will be mapped as ways and a few others as relations.

You have to change your query in order to search for all three elements:

Your image is 4-channels of 32-bits each. PIL doesn’t support such images - see Available Modes here.

I would suggest tifffile or OpenCV’s cv2.imread(…, cv2.IMREAD_UNCHANGED)
