So my code works as intended, but suffers major performance issues every time I add a new object to the screen. The speed of my objects basically gets cut in half.
All you have to do to observe this is run the code and hit spacebar to create a new object. it is suppose to represent a productio...
Today I started learning C++ and at the end of the day have made a simple generic matrix class. I'm looking for feedback on techniques and features. It's still not complete, though. But everything works!
I put some functions outside the class and inside a namespace because I was trouble defining...

I have created a basic web page that contains a panel which displays some details about an object, and a panel which contains some tiles that are used to choose which object to view. The idea is straight-forward, and with plenty of C# experience, the learning curve was small. However, since I am ...

I'm writing a loss function for a linear classifier. The function takes in several arrays and outputs the loss. 's' is a score array which contains 10 entries that are the scores for each class. y is the array that contains the correct class assignments. My loss function takes the max of 0 and th...

I have been developing an API for my product for the first time. I am bit confused whether the way I have designed the endpoints are correct or not.
For example, I have a POST endpoint when updates a record when called and it is like so.

Is it better to do
Result = random(36)
Dice1 = Result/6+1
Dice2 = Result%6+1
Or
Dice1 = random(6)+1
Dice2 = random(6)+1
Would there be more bias on second option or first option
I am using a panda's dataframe and I am doing filtering and some calculations per column and per row.
The dataframe looks this:
100 200 300 400
0 1 1 0 1
1 1 1 1 0
Each header of the dataframe represents a company ID (x) and the rows represent specific users (y)...
How can I avoid the unchecked cast warning when using generics when IDE is too dumb to realize I actually checked it?

I have two processes. First (main) one is "dealing" with user stuff. Second one is doing some internal stuff and should update its internal state according to user actions. So I've created two pipes. By one I send actions to subprocess, from another I get messages that emits this subprocess.

Why did this recent question: FizzBuzz in Javascript get so many views and presumably more votes? My initial theory was that it contains the tags fizzbuzz and possibly that tag combined with javascript, though I created a related question with those same tags (plus a couple others) and (at the ti...
I recently tried to optimise some code by using parallel processing, putting two cores to work on the problem instead of one.
For whatever reason it didn't work, I don't know why, but I doubt much can be done about the reason why it didn't work, on the other hand posting the failure might save s...

I know randomness in programming can be a deep topic, and searching the topic seems to result in Fisher-Yates being the best method, but I'm curious what people would say about this method.
Basically, since I have the cards as objects, I just add a property of a random number then sort the entir...

Task: convert this array of hashes:
animals = [
{"cats" => 3},
{"dogs" => 5 }
]
to this hash:
{
"cats" => 3,
"dogs" => 5
}
This is my solution, any feedback is appreciated :-)
animals.reduce({}) {|m,e|
e.each{|k,v| m[k] = v}; m
}
