I am trying to add a ruby tag for every word in a paragraph. The html doc looks somthing like this

I am very new to postgreSQl and SQL and databases, I hope you guys can help me with this, i want to know which posts have the most amount of comments and which have the least amount of comments and the users need to be specified too.

I am analyzing stock trend though SMA 15 as follow:

1. If closing price value leads its MA15 and MA15 is rising for last 5 days then trend is Uptrend i.e. trend signal is 1.

2. If closing price value lags its MA15 and MA15 is falling for last 5 days then trend is Downtrend i.e. trend signal is 0.

3. if none of these rules are satisfied then stock market is said to have no trend.

I knoww how to do two conditions the first and the second, but I want to add the third with no trend.

I use an online music player called "Netease Cloud Music", and I have multiple playlists in my account, they hold thousands of tracks and are very poorly organized and categorized and held duplicate entries, so I want to export them into an SQL table to organize them.

I have found a way to view the playlists without using the client software, that is, clicking the share button on top of the playlist page and then click "copy link".

But opening the link in any browser other than the client, the playlist will be limited to 1000 tracks.

But I have found a way to overcome it, I installed Tampermonkey and then installed this script.

Now I can view full playlists in a browser.

This is a sample playlist.

The playlists look like this:

The first column holds the songtitle, the second column holds the duration, the third column holds the artist, and the last column holds the album.

The text in the first, third and fourth columns are hyperlinks to the song, artist and album pages respectively.

I don't know a thing about html but I managed to get its data structure.

The thing we need is the table located at xpath //table/tbody, each row is a childnode of the table named tr(xpath //table/tbody/tr).

this is a sample row:

I'm attempting to solve a set of equations related to biological processes. One equation (of about 5) is for a pharmacokinetic (PK) curve of the form C = Co(exp(k1*t)-exp(k2*t). The need is to simultaneously solve the derivative of this equation along with some enzyme binding equations and initial results where not as expected. After troubleshooting, realized that the PK derivative doesn't numerically integrate by itself, if k is negative using the desolve ode function. I've attempted every method (lsode, lsoda, etc) in the ode function, with no success. I've tried adjusting rtol, it doesn't resolve.

Is there an alternative to the deSolve ode function I should investigate? Or another way to get at this problem?

Below is the code with a simplified equation to demonstrate the problem. When k is negative, the integrated solution does not match the analytical result. When k is positive, results are as expected.

First Image, result with k=0.2: Analytical and Integrated results match when k is positive

Second Image, result with k=-0.2: Integrated result does not match analytical when k is negative

In my little game in a discord bot, this means I can't change user because it's given by the discord API, also the people who play the game enter commands in discord and don't execute the python file on their PC. I save the data of users in a json file and read the file to a dictionary when I need it. Now that I don't have to worry about KeyError when I try to read something from that dictionary, for example if I would try to read player_data[user_id]["quests"]["end"] but this wouldn't be defined, I call the function setup at the start of every command, which tests if the user's data is already saved:

I have the following data

I am running a program to scrape the website URLs from a google search of any song by any artist using the puppeteer library. I am recursively extracting the URLs from all the pages on google search. Everything works fine but when I try to close the browser using the browser.close() function doesn't work until I manually close the browser. When I manually close it then my data is logged on the terminal otherwise it doesn't. I have waited for nearly 15 minutes but still browser stays open. Following is my code
