fluster | Testing framework for decoders conformance | Messaging library

I'm a beginner coder creating a dice rolling application with react, and I've encountered a css issue that's taking me far too long to figure out. Basically, I have a row of 6 dice, and I'd like each die to sit within a background box that will change color upon react state change. I have the react aspect down, but I can't get the background boxes to sit correctly.

I'm no CSS expert, and I'm building this to gain experience with react/redux, not css, so I'm a bit flustered by how long this is taking. Any explanation of why my current code isn't working would be greatly appreciated, as there are major gaps in my understanding of display: 'flex'.

Here's my code and a screenshot of the issue:

following code:

I was in midst of reviewing some basic CS understandings but the question arose ;/ in my head.

I am wondering if there's an idea of passing by value or reference on 'functions'

Functions are one of the fundamental building blocks in JavaScript. A function is a JavaScript procedure—a set of statements that performs a task or calculates a value. -quoted from developer.mozilla

My current understanding is flustered in that when a function is saved: I do not understand how functions are passed.

Considering anything that is not primitive type is object type in javascript, the block of code is passed as reference to the function name. However, I am also told that

'Javascript always pass by value so changing the value of the variable never changes the underlying primitive (String or number).'

so does it pass by value? or by reference? so here was my attempt to test the case out:

The following ruby code to store a previous URL is meant to exclude a certain series where the resulting action might send the user in an endless loop.

Keep getting the error:

Should add a method to the prototype called speak

Expected 'DogsaysWoof' to be 'Dog says Woof'.

Thought I nailed it but something is missing. I put the spaces "" between the properties but it still comes up 'DogsaysWoof'. Think it is because I am missing a reference to the method to the prototype but it seems not to matter what I put in there. (Right now it is "says")

I'm a little flustered on this one.

I need for a given list of words to determine whether it contains anagrams. For example:

I know for a fact there is something pretty obvious here that I am completely missing, so your help is greatly appreciated.

I have a feature that provides two dropdowns. They contain the same data (the feature allows a trade between two people, the people is the data), but I want them each to get their own copy of said data.

Another part of this feature is that by picking Person A in the first dropdown, I want to disable Person A in the second dropdown, and vice versa, so I have the ng-options tag paying attention to a disabled property on the object.

The issue I have is that even with using a method such as Lodash's clone to properly create a "new" array upon first time assignment, every time I access Person A in ONE array (and specifically do NOT access the other array) invariably I am seeing that when I touch Person A, that object is updated in BOTH arrays, which has me flustered.

This feels like a down-to-the-metal, barebones Javascript issue (standard PEBCAK, I feel like I'm clearly misunderstanding or straight up missing something fundamental), maybe with a bit of AngularJS rendering-related fun-ness involved, but... What gives?

I've been flustered over trying to figure out how to call a method from an instance of a class from a different class. For example:

I nearly completed a DES implementation for a school project when...

I ruined my source code with tar & bzip2.

The command was: tar cjvf des.cpp des.h main.cpp > des_implementation.tar.bz2

I tried to create a compressed archive to send to a friend. To my horror, when I opened the source code in CLion (des.cpp, des.h, and main.cpp), I found that des.cpp was completely ruined and CLion was displaying an error: File was loaded in the wrong encoding: 'US-ASCII'.

Here is a sample of the file's contents: BZh91AY&SY©fZ�×ÿÐÞ°�ÀY÷ÿÝ¿ïßÊÿïÿê���PÞáó``Í®:D4i¢4Òz¦5=OPÞ¤iâSÚ£@õ�å

I've also tried unzipping the zipped filed, but to no avail. I thought the command would create a separate .tar.bz file and leave the originals alone?

Main questions:

1. How did this happen?
2. How can I make sure it never happens again?
3. How can I fix this?

I am flustered and desperate, any help would be appreciated.
