I made some Tetris wall art recently, and it only moves pieces randomly (though you can optionally control it via a connected PC's keyboard)
I wanted to make it strategize. How hard could it be, really?
[cs/0210020] Tetris is Hard, Even to Approximate[^]
Hard enough that it's an NP problem in many circumstances and there are research papers on the problem. 
I didn't say it had to be good. But apparently even playing badly is almost as hard as playing well.

I recently learned there's a whole community of tetris players who try to beat best scores.
Its was believed there was a best score x and after that pieces moved so fast that it was impossible to get it right.
That was until someone invented "tapping", where you could hit the buttons a lot faster.
Then they got to buggy levels because of some color schemes.
People got past that too.
This is how I learned: After 34 Years, Someone Finally Beat Tetris - YouTube[^]

The old freeware Hyperoids changed your ship color each level.
If you made it to level 16, your ship would match the background! Maybe the bullets as well.
A lot harder situation with Tetris!

I was expecting a cat βtamagotchiβ based on earlier posts.

I love closures and lambdas, but I was quite amused when I wrote the following buggy code:
for (int i=0; i <= 10; i++)
{
var task = Task.Run(async () =>
{
var convertResp = await StartTestConvert(i);
... other stuff
});
}And was wondering, how in the world does i get equal to 11!!! 
Answer: bad closure. Fix:
for (int i=0; i <= 10; i++)
{
int n = i;
var task = Task.Run(async () =>
{
var convertResp = await StartTestConvert(n);
... other stuff
});
}
I think this would make a good interview question!

And I thought this was fairly common knowledge! 
(Not that that would preclude it from being an interview question, of course.)
They "fixed" the behaviour for the foreach loop back in C# 5, but deliberately chose not to change the for loop:
UPDATE: We are taking the breaking change. In C# 5, the loop variable of a foreach will be logically inside the loop, and therefore closures will close over a fresh copy of the variable each time. The for loop will not be changed.

That's the follow-up interview question. "On what for loops does closure work?"
|
|
|
|
|
From my experience there are most probably programmers who would fix it like this 
for (int i = 0; i <= 10; System.Threading.Thread.Sleep(10), i++)
{
....
}

I do not see the difference whether using i or n.
Is async call creating a thread?
Is this a C# thing?
lambda?
Closure? seems like a definition of global and local variable spaces.
