kandi X-RAY | cobra Summary

cobra is a Python library typically used in Networking, Websocket applications. cobra has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can install using 'npm i cobras' or download it from GitHub, npm.

Cobra is a realtime messaging server using Python3, WebSockets and Redis Streams. It was presented in great details during RedisConf 2019. Since then we've added history support which let cobra retain messages published to a channel that no-one is subscribed to. This makes it easier to blow up your systems through OOMs and fill your hard drives, but it makes cobra much more useful. Cobra has been used in production receiving heavy traffic for about a year. Since it was written in Python it was named after a snake as an hommage to a great programming language. There are 4 operations that a client can execute against a cobra server: publish, subscribe, read and write. publish and subscribe are the 2 operations core to a group-chat. read and write are the typical operations that key value stores (such as memcached), or a python dictionnary provide. Interested ? Go read the docs ! If things don't work as expected, please create an issue in github, or even better a pull request if you know how to fix your problem.

How do i create hyperlinks for every button in a list? [Tkinter]

Asked 2022-Apr-09 at 14:53

I have made a list of buttons yesterday, and i wanted to step it up a little by adding a hyperlink for each item in the list. However, pressing each button results in nothing at all (In fact, I believe a 'None' was resulted from this). All the YouTube links were made into an array, and for each item, i have tried to assign a hyperlink.

Here is the code for this:

I made the following modifications to your code:

Removed callback and used lambda to open the corresponding YouTube video.
Used zip to pair-wise extract the exercise name and the video link.

If you want to know why I wrote lambda x=link: webbrowser.open_new(x) and not lambda : webbrowser.open_new(link) refer to this question.

How can i insert a list of buttons into text with a scrollbar?

Asked 2022-Apr-08 at 15:28

I'm a student coder. I would like to create a list of buttons. However there are too many buttons to fit onto a single screen. I have tried to incorporate a scrollbar, however the buttons do not go inside the textbox, even after setting the window to 'text'.

Here's what ive tried:

ANSWER

First you need to use my_text1 as the parent of those buttons if you want to put them into my_text1.

Second you need to use my_text1.window_create(...) instead of .pack() to put those button into my_text1.

Final yscrollcommand = text_scroll should be yscrollcommand = text_scroll.set instead.

QUESTION

Combine graphs from two different datasets

Asked 2022-Mar-09 at 20:44

I am trying to see how word frequency correlates with phonotactic probability using R, but there are a few issues. First, and most generally, I don't know merge these two graphs together (i want them to appear on the same axis).

This leads to a second problem because the first graph's y values are in probabilities, and the second is a count, so the scales are not the same. Should I combine data frames first, or is there a simpler way to merge two graphs?

Here is the reproducible sample, and the code for my graphs:

Answered 2022-Mar-09 at 20:44

One way could be to use a second y axis. Although this method is to be used critically, in this situation I think it is appropriate:

QUESTION

Link another Golang Cobra CLI to current Golang Cobra CLI

Asked 2022-Mar-01 at 14:31

I am working on a new Golang Cobra CLI, which handles several commands. I later on found out that there is already an existing Golang Cobra CLI that handles some commands that I will be covering in the new CLI, but not all. In other words, my new CLI cover all commands of the existing CLI with some extra commands.

Is it possible for us to link the existing CLI into the new CLI?

Note: I am not sure whether "link" is the best word to describe what I am interested to do. In case this is already answered before on SA, feel free to mark this as duplicate.

I think your best bet is to fork the other repo with fewer commands, then edit it to add your commands. Assuming that both repos are open source.

If your code is closed-source then you can bring in their repo as a dependency.

Install cobra

cobras init needs to be run once to generate an app configuration file, in ~/.cobra.yaml. That file contains all the roles, secrets and apps configured. Clients will use this data to authenticate. To run in production you will need a redis (version > 5) instance. Here are environment variables that you will likely want to tweak, to connect to 2 redis instances (for scalabity), and to bind on 0.0.0.0 so that the internet can see your instance.
