piet | An abstraction for 2D graphics | Graphics library

Idea is create DataFrame with changed order first in concat with rename, remove rows with missing values and possible duplicates and change original values by DataFrame.update:

Remember, code behind can use full file system - like any desktop code.

But if you going to use that file in the asp.net (web side), then you MUST be able to produce a valid URL path name.

So ALWAYS keep in mind the above:

Codebehind - path names are STANDARD windows file path names (and even "\" etc.).

Web pages - markup = valid URL's mapped by the web site.

If you confuse the above two concpets above? you be in for a world of pain by ignoring the above VERY simple idea.

So, you need TWO things to convert those path names to valid WEB links:

First up: The web server "site" needs rights and a "means" to point to a given folder in question.

So, you might have some say SAN or big network storage device - and you toss/place/have/put your files there.

Say like this:

I was able to get all of the drawing (creating the grid and the text) down to 4-5ms by:

• Caching values where possible (Random, StringFormat, Math.Pow)
• Using ArrayPool for scratch buffer
• Using the DrawString overload accepting a StringFormat with the following options:
  • Alignment and LineAlignment for centering (in lieu of manually calculating)
  • FormatFlags and Trimming options that disable things like overflow/wrapping since we are just writing small numbers (this had an impact, though negligible)
• Using a custom Font from the GenericMonospace font family instead of SystemFonts.DefaultFont
  • This shaved off ~15ms
• Fiddling with various Graphics options, such as TextRenderingHint and SmoothingMode
  • I got varying results so you may want to fiddle some more
• An array of Color and the ToArgb function to create an int representing the 4x bytes of the pixel's color
• Using LockBits, (semi-)unsafe code and Span to
  • Fill a buffer representing 1px high and size * countpx wide (the entire image width) with the int representing the ARGB values of the random colors
  • Copy that buffer size times (now representing an entire square in height)
  • Rinse/Repeat
  • unsafe was required to create a Span<> from the locked bit's Scan0 pointer
• Finally, using GDI/native to draw the text over the graphic

I was then able to shave a little bit of time off of the actual saving process by using the Image.Save(Stream) overload. I used a FileStream with a custom buffer-size of 16kb (over the default 4kb) which seemed to be the sweet spot. This brought the total end-to-end time down to around 40ms (on my machine).

The specification you linked to seems pretty clear:

gl_StorageSemantics* and gl_Semantics* values should be bitwise ORed together to generate the SPIR-V Semantics enums

And it also specifies how the GL atomic functions map to SPIR-V atomic operations. So the answers you seek are in the SPIR-V specification. And the deep details are defined by the Vulkan memory model, appendix B of the Vulkan specification.

At the end of your for loop, 'df' keeps the last 'node' key of your json. You have to append all 'nodes' keys in a single dataframe instead.

Extending your code:

The result you expected isn't a possible dictionary. The closest possible would be this:

In formatString you modify %rbp with subq %rax, %rbp, forgetting that you will restore %rsp from it. So when you mov %rbp, %rsp just before the function returns, you end up with %rsp pointing somewhere else, and so you get the wrong return address.

I guess you are subtracting some offset from %rbp to get some space on the stack. This seems unsafe because you've pushed lots of other stuff there. It is safe to use up to 128 bytes below the stack pointer as this is the red zone, but it would be more natural to use an offset from %rsp instead. Using SIB addressing you can access data at constant or variable offsets to %rsp without actually changing its value.

How I found this with gdb: by setting breakpoints at myPrint and endPrint, I found that %rsp was different at the ret than it was on entry. Its value could only have come from %rbp, so I did watch $rbp to have the debugger break when %rbp changed, and it pointed straight to the offending instruction in formatString. (Which I could also have found by searching the source code for %rbp.)

Also, your .text at the top of the file is misplaced, so all your code gets placed in the .data section. This actually works but it surely is not what you intended.

Is this what are you looking for?

Get the path to the entry whose first_name is Jan as an array, and extract the country name from it.
