plog | Portable , simple and extensible C++ logging library

i try to get pugixml running in github actions. And i would be happy with any solution that is working...

I added the download to the cmake.yml

I made my own linux distribution with buildroot. In "make menuconfig" and "make linux-menuconfig" I checked all options related to "ppp" and "pppd". Unfortunately, after building my distribution I can't use the commands "pon", "poff", "plog" and probably others. The system cannot see them. I looked and they are not in "/ usr / bin" or "/ usr / sbin". What could be causing this? I found out somewhere that these are debian-only commands, but how can I enable the pppd daemon?

I'm trying to dockerize a basic CRA template created through npx create-react-app project-name, of which Dockerfile would look like:

I have the following code in my app:

I have been working on a idea for a system where I can have many workers that are triggered on a regular basis by a a central timer class. The part I'm concerned about here is a TriggeredWorker which, in a loop, uses the mutex & conditionVariable approach to wait to be told to do work. It has a method trigger that is called (by a different thread) that triggers work to be done. It is an abstract class that has to be subclassed for the actual work method to be implemented.

I have a test that shows that this mechanism works. However, as I increase the load by reducing the trigger interval, the test starts to fail. When I delay 20 microseconds between triggers, the test is 100% reliable. As I reduce down to 1 microsecond, I start to get failures in that the count of work performed reduces from 1000 (expected) to values like 986, 933, 999 etc..

My questions are: (1) what is it that is going wrong and how can I capture what is going wrong so I can report it or do something about it? And, (2) is there some better approach that I could use that would be better? I have to admit that my experience with c++ is limited to the last 3 months, although I have worked with other languages for several years.

Many thanks for reading...

Here are the key bits of code:

I am building a simple feedback system for a study. I have just started to learn JS and D3.js, but decided to build some very simple plot in D3.js. However, I get the following error message and I don't understand how I can fix it?

(index):36 Uncaught (in promise) TypeError: data.forEach is not a function

What I want to do with this script is to take a single line in a .csv and put the number on the screen. This my code

I have a data frame (pLog) containing the number of reads per nucleotide for a chip-seq experiment done for a E. coli genome (4.6MB). I want to be able to plot on the X axis the chromosomal position and on the Y axis the number of reads. To make it easier, I binned the data in windows of 100bp. That makes the data frame of 46,259 rows and 2 columns. One column is named "position" and has a number representing a chromosomal position (1,101,201,....) and the other column is named "values" and contains the number of reads found on that bin e.g.(210,511,315,....). I have been using ggplot for all my analysis and I would like to use it for this plot, if possible.

I am trying for the graph to look something like this:

but I haven't been able to plot it.

This is how my data looks like

I want to make use of the requests module backoff strategy outlined at https://stackoverflow.com/a/35504626/1021819, the code reproduced from that answer being:
