solar-system | A solar system developed with three.js | Graphics library

I have been exploring APIgee and okta configuration using https://github.com/tom-smith-okta/okta-api-center repo. Here APIgee edge acts as a gateway to https://okta-solar-system.herokuapp.com/ api’s and the token for authentication is generated via okta. My understanding is that https://okta-solar-system.herokuapp.com/ doesnt have any okta authentication enforcement. The check is via apigee.

If I were to replace https://okta-solar-system.herokuapp.com/ with a spring boot application hosted publicly should the application have okta security enabled (eg : https://github.com/oktadeveloper/okta-spring-boot-oauth-example) or should i follow same procedure as above and delegate enforcement of token to apigee, without any security enforcement on the spring boot application?

Can someone tell me what is the standard way of implementation I should follow?

I'm trying to do a numerical integration of the solar system. I did this before in plain Scheme, now I want to do it using the very interesting SCMUTILS-library from MIT. What I did:

1. I took solar system data from the Jet Propulsion Laboratory; that is: the mass, the position and the velocity of the sun, mercurius, venus and earth in barycentric coordinates.
2. I wrote code for the differential equation, such that every object in the system (sun, mercurius, venus, earth) gets attracted by the 3 others in the correct way.
3. I ran the simulation through numerical integration using SCMUTILS.

If I run the simulation with the sun + 1 other planet, it works. If I try to take the sun + 2 other planets, it seems to hang. This is strange as I ran the simulation with the same data a few years ago with my own home-built Runge-Kutta integrator, and that worked fine.

Note that I'm well-known with MIT-Scheme and numerical integration, and that I only want to learn SCMUTILS. I'm doing something wrong clearly, and it would surprise me if this problem couldn't be tackled with SCMUTILS.

Also, I'm not fixed on my code: if somebody can provide me with a working implementation in SCMUTILS, then that's fine as well, as long as I understand what I'm doing wrong in my program. I just want to use SCMUTILS in an idiomatic way...

My code is below (about 60 well-documented lines). Thanks for any comments or improvements towards a working simulation.

I have a parent div that contains 4 equal divs (25% each), horizontally side by side, containing an image. I want the div to expand on click, such that the div animates to cover the whole parent div (100% width). And then some text animates in over the image.

I'm trying to do this via flex box in css, but even though the clicked div expands it doesn't cover the complete parent div. The remaining 3 div shrink but do not completely disappear.

I also tried doing this via Javascript, by adding the property display: none to all the other divs. However, this doesn't allow me to add any animations.

I am working on a game, and I want to use this text file of mythological names to procedurally generate galaxy solar-system names.

When I read the text file, I tell the while-loop I'm using to continue if there is something that's not a name on a given line. That seems to throw an exception in some (not all) areas where there are multiple lines without names.

How can I make the program work without throwing exceptions or reading lines without names on them?

My Code:

I am trying to use an external js file in my .vue file but get error:

I have a yaml file which has nested maps in it:

I am building a RESTful API where I have a resource named solar_systems. solar_sytems has id(int), system_size(int), system_cost(int) columns with many other columns.

I understand that API endpoints will be-

/v1/solar-systems - for all systems

/v1/solar-systems/{id} - for a single system

And I have to pass query params for filter, search, sorting etc.

But what will be the best practice for API endpoints if I need some kind of custom data like if I need average system_cost for each system_size.

Will it be silly, if I use - /v1/solar-systems/average-system-cost?

Please I need your opinion from your experience.

I want create an effect like this a link!. (The name of the planet in the background)

So i need to generate many random letter before to display letter of my word one by one.

In my test, i try to display the word moon in my div.planet-name, letter by letter with a delay of 1000ms. And Before display a letter of Moon i want generate many random letter.

But when i use the function randomLetterEffect i stay blocked on the first letter and the word moon doesn't appear !

why i don't generate random letter in text.substring(0, 1), text.substring(0, 2), text.substring(0, 3), etc ... but only in text.substring(0, 0) ?

i try this :

It has a horizontal scroll despite me using rows and columns to fill it up.

Here is the GitHub repository. I cannot seem to find anything of importance that can remove the bar.

I am aware that I can fix it with:
