This project shows a graph where the nodes are programming languages and the edges are compilers. The graph is drawn using [Cytoscape.js] particularly the [CoSE layout module] The data for the list of compilers is sourced from the [compilers.js] module.

QUESTION
I have a text file called listofhotelguests.txt where hotelguests are stored line by line with their first names separated by && as a delimiter. Can someone explain how I can have my Python program read it so it associates john with doe, ronald with macdonald, and george with washington?
My expected outcome I'm hoping for is if I prompt the user for their lastname to make sure their a valid guest on the list, the program will check it against what it has in the file for whatever the firstname they entered earlier was.
So if someone enters george as their first name, the program retrieves the line where it has george&&washington, prompts the user to enter their lastname and if it doesn't match what it has, either say it matches or doesn't. I can figure the rest out later myself.
Assuming there is nobody with the same names.
I know I have to split the lines with &&, and somehow store what's before && as something like name1 and whats after && as name2? Or could I do something where if the firstname and lastname are on the same line it returns name1 and password1?
Not sure on what to do. Python is one of my newer languages, and I'm the only CS student in my family and friend groups, so I couldn't ask anybody else for help. Got nowhere by myself.
Even just pointing me in the direction of what I need to study would help immensely.
Thanks
Here's what the text file looks like:

I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.
CountryDetails.js
...ANSWER
Answered 2021-Jun-15 at 17:07The issue seems to be that you are already on the "/country/:name" path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail is already mounted it neglects to recompute the item and allCountries state. This is because the useEffect hook only runs once when the component mounts.
The name param (match.params.name) is actually a dependency for the GET requests, it should be added to the useEffect hook's dependency array.

ANSWER
Answered 2021-Jun-15 at 16:37Use map instead of forEach. forEach returns a void. Remove [] too otherwise you need to use the spread operator. Add async-await wherever necessary because I can see listen callback is async.
QUESTION
As you might know, most common video container files are like zip archives that contain several other files: the actual video, several audio files for different languages and several text files for subtitles and captions. If these tracks are included in the video file, that's called packaged afaik.
Now, while HTML offers the element to reference additional files, are browsers capable of choosing among different packaged tracks and display different subtitles?
How is browser support?
...ANSWER
Answered 2021-Jun-15 at 14:13No, they can't, even though the HTML standard encourages browser vendors to implement such controls.
The standard allows several audio and video tracks per media resource, and exposes them via JavaScript:
A media resource can have multiple embedded audio and video tracks. For example, in addition to the primary video and audio tracks, a media resource could have foreign-language dubbed dialogues, director's commentaries, audio descriptions, alternative angles, or sign-language overlays.
4.8.12.10 Media resources with multiple media tracks
Additionally, the standard encourages controls for different audio tracks and captions.
If the [control] attribute is present, […] the user agent should expose a user interface to the user. This user interface should include features to […] change the display of closed captions or embedded sign-language tracks, select different audio tracks or turn on audio descriptions […]
QUESTION
I'm trying to make a relation between my Book entity and a list of languages that I retrieve through a service. In my database, each book has a: ID, TITLE, CATEGORY_ID (FK), LANG_ID
Book.java:
...ANSWER
Answered 2021-Jun-15 at 12:54First of all, did you consider to store language in your database? I mean language are mostly the same, doesn't change too often, you can also store in a properties file and read them at runtime to use them later.
Anyway, I think you should:
- first get from external system languages
- store in variable / in memory cache ( like a Map where you can store id and name )
- read your data from database
- for each row you do
- read book language id, read the cache, get out data you need
- for each row you do
If you can't change model, just use a dto with your entity and the language and you're fine

QUESTION
I am working on an integration into an old API which for some reason returns the json data as a text/html response. I have tried to Deserialse this string using Newtonsoft in C# and also using various javascript libraries including JSON.parse() but all have failed.
The actual response looks like a valid json object but it fails to get deserialised:
{"err":201,"errMsg":"We cannot find your account.\uff01","data":[],"selfChanged":{}}
I am taking it that there are some special characters or that the actual response is in a format that any of my parsers cannot not deserialise out the box. I have attached various code samples in various languages including curl. I would really appreciate if someone could help deserialise the response object in C# or point me in the right direction.
C#

Answered 2021-Jun-15 at 11:45This can be done in C# by customizing the JsonMediaTypeFormatter (from the NuGet package Microsoft.AspNet.WebApi.Client) like so:
