I have an Entry that I want to give a red outline when the entry is empty. I'm using SyncFusion's SFTextInputLayout for my Entry and it has a property HasError that once it's set to true, it'll automatically highlight my entire in Red.
Here is the following XAML code for SFTextInputLayout

I'm trying to set up a system where I can have an arbitrary number of parallel tasks, all of which wait for a go signal, do their work, and then stop while a manager collects the results, prepares for the next batch of work, and so on.
The easy way I know to do this is to launch a packaged_task for each job, for each i... | stackexchange/codereview |
I've never had a serious attempt at writing an encryption algorithm before, and haven't read much on the subject. I have tried to write an encryption algorithm (of sorts), I would just like to see if anyone thinks it's any good. (Obviously, it's not going to be comparable to those actually used, given that it's a first... | stackexchange/codereview |
I believe this set of code is very repetitive in a way where every method does almost the same task but it is repeated multiple times. This is what the code looks like and its main purpose is to display the intended design on the simulator:

button1 = new JButton("start");

My first program using Classes, it should allow you to set the price of three different pumps, times how long you pump, then calculates what you owe, and updates the amount of gas left in the pump.

Ram was busy calculating the factorials of some numbers. He saw a
pattern in the number of zeros in the end of the factorial. Let \$n\$ be
the number and \$Z(n)\$ be the number of zeros in the end of the factorial
of n then for
\$x < y\$
\$Z (x) \leq Z(y)\$
i.e. the function never decreases.

Everything works, i just want to know if i can change the way the xml tags are retreived. This way seems a bit bulky - but i could be wrong. Thoughts?

Output should be an object ({cal: val}), with soonest possible time throughout all calendars recommended times from the data.
My question is: is this approach over complicated and if so, what should be the proper way to solve that task?
Incoming data is an object:
let data = [

The following is used to create a masonry effect with varying height rectangles. How can I simplify and make this more elegant in Unity?

I decided to write a pathfinding algorithm in order to expose myself to the world of pathfinding and for me to further understand more advanced algorithms such as A*. I chose C# due to its flexibility compared to other languages such as Java.
I will start with the basic objects and work up to the more complex ones.

Given an infinite stream with the property, such that after all 0's there are only all 1's, find the index of the last 0.
I'm looking for code review, best practices, optimizations etc. Verifying complexity to be O (log n) where n is the first 1 encountered in the search (not the first 1 in the stream).

This is "my" version of a basic C++ calculator, that requires a single line input (like 1+1) to calculate the result. I have been (self)learning the language for 2 months now. I don't pretend to have invented this code, but I haven't taken the time to search for this variation.
The functions included are:
