kandi X-RAY | feynman Summary

feynman is a JavaScript library typically used in Tutorial, Learning applications. feynman has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

A javascript application for creating feynman diagrams. Live at feynman.aivazis.com. This repo started as a migration of my original feynman diagram application to a leaner flask server. It then evolved from a badly written angular 1.2 application to a less-badly written react/redux app. During that time, the backend (responsible for rendering latex) was also rewritten from python to golang.

How to remove some portion of an image

Asked 2021-Dec-28 at 14:45

I am trying to build a component, where it takes images and the first image will be shown while remaining images will be shown in a half circle.

Here I am trying to clip the image portion from second image by adding a class which is not working. I need to get the images as shown in the attached image below.

You can use clip-path: path() to create custom shapes. This is now supported in modern browsers.

How to convert 0-1 image float array to 0-255 int array

Asked 2021-Oct-09 at 23:14

photo*=255
plt.subplot(122)
plt.imshow(photo)

ANSWER

Answered 2021-Oct-09 at 22:40

The issue is photo*=255 is still an array of floats.
- Look at the photo array.
- Add photo = photo.astype(int) after photo*=255.
- X in .imshow should be int type when the array is 0-255: (M, N, 3): an image with RGB values (0-1 float or 0-255 int)

QUESTION

How to target images placed by a for loop in JavaScript?

Asked 2021-Aug-14 at 07:20

I've created a table using entirely JavaScript.

The table consists of 3 columns, where one of the columns contains only images in each of the rows. I'm trying to make it where when the user clicks one of the images in the columns, it toggles between two images.

I would have an idea of how to do this if it was just one image assigned to a variable, but since these images were placed by a for loop into a table, there doesn't seem to be any easy way to target them.

How do I do this? I've heard to use the onClick function, and I tried that first, without any success. Here's what my code looks like for that:

...

ANSWER

Answered 2021-Aug-14 at 07:01

When you build your table add one listener to the table element. This method uses event delegation - when you click on an element inside the table the event "bubbles up" the DOM and it caught by the listener on the parent element. A check to see if the target element is an image is all that's needed.

QUESTION

How to record mic WHILE video calling with Daily.co on iOS Safari

Asked 2021-Jul-02 at 19:48

Problem

With my iPad's iOS Safari, I can use Daily.co's video API to call other devices. But the moment I start recording my local microphone via the audio-recorder-polyfill library , everybody else will no longer be able to hear me, even though I can still hear them and share my camera. Even when the recording session ends, the audio call remains broken (though the audio-recorder works successfully).

It seems iOS specific, because I have no problems with my Surface's Windows Chrome.

How to reproduce Takes around 2 minutes

Visit explain.mit.edu with iPad Safari and any other device. Press the green call button.
After confirming the video call works, press the record button on iPad
Note the other device can no longer hear anything

What I tried

First, I guessed the MediaRecorder invalidates the Daily video call's access to the mic, so I used setLocalDevice to re-designate access to Daily every 5 seconds to see what would happen. It made no difference during recording, but when the recording ended and it actually did restore the audio call.

So the remaining problem is that the audio call stream just doesn't work mid-recording: I read the MDN docs about the MediaCapture API, it mentioned that a stream has one input and one output, but I don't know what that really means, and whether a mic stream can be simultaneously accessed by two "things".

Relevant Code

I only use the basic minimum API that Daily and audio-recorder-polyfill provides

We can work on a repro case for this, but I have a guess as to what's going on. iOS Safari in the past has stopped any current tracks coming from the local mic/cam any time getUserMedia() is called. So, unlike on desktop browsers and Android Chrome, on iOS you can't request or use multiple streams.

iOS Safari is a moving target, and I haven't looked at this specific issue lately. But if that is what's going on, probably you can work around it with a fairly small code change.

QUESTION

How does Elasticsearch aggregate or weight scores from two sub queries ("bool query" and "decay function")

Asked 2021-Jun-13 at 15:43

I have a complicated Elasticsearch query like the following example. This query has two sub queries: a weighted bool query and a decay function. I am trying to understand how Elasticsearch aggregrates the scores from each sub queries. If I run the first sub query alone (the weighted bool query), my top score is 20. If I run the second sub query alone (the decay function), my score is 1. However, if I run both sub queries together, my top score is 15. Can someone explain this?

My second related question is how to weight the scores from the two sub queries?

...

ANSWER

Answered 2021-Jun-13 at 15:43

I found the answer myself by reading the elasticsearch document on the usage of function_score. function_score has a parameter boost_mode that specifies how query score and function score are combined. By default, boost_mode is set to multiply.

Besides the default multiply method, we could also set boost_mode to avg, and add a parameter weight to the above decay function exp, then the combined score will be: ( the_bool_query_score + the_decay_function_score * weight ) / ( 1 + weight ).

How to make my Google Scholar account searchable?

Asked 2021-May-18 at 20:58

I recently created my Google scholar account. I linked my account to my school email address and my papers. I also made the profile public. However, my profile is still not searchable by others.

I would like to create a hyperlink for my name in some way. For example, if you search Richard Feynman on Google scholar, his name has a hyperlink and we can access his other papers from it.

Does anyone know how to set up this hyperlink? Is it only allowed to a famous author or research with tons of publications?

Search Inside Dropdown with data in tree structure React JS

Asked 2021-Apr-24 at 10:19

I have developed a custom component which renders dropdown with a tree like structure inside it and allows the user to search for values inside the dropdown. Somehow the search works only after two levels of the tree structure.

For Example:

We would be able to search only on the inside of NextJS label. The previous levels do not render results.

My function looks like this:

ANSWER

Answered 2021-Apr-24 at 10:19

I haven't looked at the context that this is used in, so apologies if I'm missing something about how this is supposed to work. I've assumed that you can call setFound after running this function based on whether it finds anything or not and that it only needs to return one value. But hopefully this helps.
