juncture | Fast trading protocol library for the JVM | Cryptocurrency library

My query is relatively straightforward. There exists a structure called war_name with the following definition:

I've tried both make and cmake to compile and deploy libpqxx but simple code does not seem to work. https://github.com/jtv/libpqxx/blob/master/BUILDING-configure.md. I installed the library using the instructions on the official Git repo but am still getting issues with build step in Codelite project.

Codelite project configuration:

1. Makefile generator Default
2. Compiler GCC
3. Compiler options: -g;-O0;-Wall -lpqxx -lpq

I can see the libpqxx libraries when I list installed libraries:

I am new to coding and have set myself a goal.

The goal has four parts:

1. Extract iOS Reminders from my iPhone using Shortcuts
2. Transform the resulting JSON file in Google Apps Script
3. Load the data into a table in Google Sheets
4. Present the reminders in an insightful way.

At this juncture, I can view the array in Google Apps Script using this code:

I was going through the passage pertaining to the access of individual elements of a 2D array using pointers.

It suggests the following mechanism to access the i^th row's j^th element of the 2D array arr[5][5]:

*(*(arr+i)+j)

From my cursory understanding of pointers, I am given to understand that the name of the array yields the address of the 0^th element of the 0^th row, and that any integral increment to the array will yield the base address of the next row. All's fine till this juncture, I suppose.

However, what I fail to understand is the relevance of the indirection (*) operator within the following snippet:

*(arr+i)

How is the indirection operator in this case relevant? Since the name of the array itself yields the base address of the 0^th row, adding any integral number to it entails it to point to the base element of the next row. In that case, the following snippet yields the address of the i^th row:

(arr+i)

And the addition of j warrants the pointer to point to the j^th element of the said row.

However, in the following snippet:

*(arr+i)

Wouldn't the addition of the indirection operator cause it to yield the i^th element of the row, as opposed to the address of the base element of the i^th row?

Should not the following be the code to access the i^th row's j^th element?

*((arr+i)+j)

In the aforementioned case, incrementing arr i times will entail the code fragment (arr+i) to point to the base address of the i^th row, and then the addition of j will entail the address of the i^th row's j^th element, and then the indirection operator (*) would yield the element that the specific address holds, wouldn't it?

Is my reasoning satisfactory?

I'm drawing some lines and arcs using SkiaSharp on a SKCanvasView (Xamarin.Forms) under Android 11.

I create the SKPath, and it mostly renders as expected, but I'm finding that the Close() stroke always ends at the start-point of the last-added Arc rather than at the 1st point in the path.

Code:

i capture this 64-bit time format from a game and trying to understand it. I can not use a date delta because every now and then the value totally changes and even becomes negative as seen below.

I am trying to create a function to manipulate different datasets for but am facing several issues with this task. I am providing a simplified version of the data I am trying to manipulate in the dput() output below:

structure(list(id = structure(c(2, 4, 6, 8, 10), label = "iid", format.spss = "F4.0", display_width = 0L), A = c(13, 9, 14, 14, 13), B = c(12, 0, 9, 3, 10), C = c(13, 8, 14, 13, 11)), row.names = c(NA, -5L), class = c("tbl_df", "tbl", "data.frame"))

There are several things I am trying to do, but I get stuck at different junctures because of the way the data is formatted. First I need to sum up the values from columns A:D for each row into a variable called total. Next, I need to compute the probability by dividing each of columns A:D by total.

Here is where I face some issues. I wrote a function to perform the above:

I am trying to create a subset of groups that have full consecutive months in R.

For instance, if there is data that look like:

Below arrow is composed out of 3 single elements. The center part should stretch horizontally so the arrow can fill its surrounding container. But as you can see in the rendered code, the stretching doesn't work. How to enable stretching and making sure, there are no gaps at the junctures. Probably, there should be a small overlap between the parts because of the antialiasing (which is mandatory).

EDIT: Using preserveAspectRatio="none" suggested by @Turnip is stretching the image, but it is producing gaps and jumps on certain widths. See this screenshot:

Can't explain this weird behavior at all!
