问题 I'm trying to get the execution/response time of an asynchronous function that executes inside a node-fetch operation, like the following async function getEditedData() { var a = await fetch(`https://api.example.com/resorce_example`); var b = await a.json(); // Some aditional treatment of the object obtained (b) console.log("End of the asynchronous function") } I Used the library perf_hooks like this, but the execution time shows before const hrtime = require ('perf_hooks').performance.now ;

问题 I run C++ program in Linux. There are several threads pool (for computation, for io, for ... such things). The system call clock() gives me a way to measure the CPU time spent by all the CPU cores for the process. However, I want to measure the CPU time spent only by the threads in the computation threads pool. How can I achieve it? Thanks :D 回答1: To get CPU clock ID of every thread you can use: pthread_getcpuclockid and using this CPU clock ID you can retrieve the current thread CPU time

问题 I'm working with canvases and i can't think of any solution, or find answer on line to my problem. I have a font that contains symbols\characters from varies sizes - heights and width. I want to draw some characters (Symbols) from the font and some on top\down of the symbol. The problem is that I can't figure out a way to have the exact height in pixels of the character that i'm drawing, and it's causes unwanted spaces between the center symbol to the one on top\down (for getting the width of

问题 After trying a lot of approaches and formulas I decided to ask this question. See this Matrix visual: WeekDate is column in a table called Planning . It's related to another date time column in another table called Export . Export table only has values for the dates: 23-Dec-19, 30-Dec-19 and 06-Jan-20 whereas Planning table has dates spanning multiple weeks in the past and in the future. Cumulative Plan Count is calculating correctly as long as there are matching dates between the tables

问题 I am trying to create a measure in powerpivot which should give me the ten lowest prices per article – and then put that measure in a pivottable to see the customer's name behind that price.

问题 I'm currently writing an eBook reader for Windows Phone Seven, and I'm trying to style it like the Kindle reader. In order to do so, I need to split my books up into pages, and this is going to get a lot more complex when variable font sizes are added. To do this at the moment, I just add a word at a time into the textblock until it becomes higher than its container. As you can imagine though, with a document of over 120,000 words, this takes an unacceptable period of time. Is there a way I
