MPMoviePlayerController currentPlaybackTime jump while set setCurrentPlaybackTime - mpmovieplayercontroller
I am using MPMoviePlayerController as my media player.
I am trying to seek by using my method (movieController is an instance of MPMoviePlayerController)
-(void)seekToTime:(NSTimeInterval)time
{
[movieController setCurrentPlaybackTime:time];
[NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:#selector(printCurrentPlaybacktime) userInfo:nil repeats:YES];
}
as you can see - after seeking I am print out the current playback time rapidly.
The problem is this - at start the current playback time is the actual new time I set.
after some time the current playback time is the old time before changing the playback time,
and after a while it's turn back to the new actual time. the result for the user is that the seek slider is jumping.
this is the log

I delete some rows (because there is a lot of them). so don't pay attention to the log date.
thanks a lot
Why don't you just use
[movieController pause]
instead?

Battleship game - how to let players place their boats?
I'm creating a battleship game in Ruby. Currently, players have 2 boats (size 3 and size 4) and I arbitrarily placed the boats by myself in the code.
Each player has its own board (array1/array2): I put a 0 when the spot is empty and 1 when there's a boat.
My question is, how can I make the players to place their ships on their board by themselves?
My idea was to ask them to enter the first point of each boat and then ask them the side (north, east, south and west) to set the orientation.
Obviously, a ship can't be placed out of bounds nor on the same space as another ship.
How can I make sure of that with my code? I have no idea where to start...
Thanks!

Going with your idea. Get user input (x,y) for start of ship Make sure that space is free (0) Create a function that checks if a ship of size N (3 or 4) would fit in each orientation. For example in pseudocode (and this can be generalized with a direction parameter): def wouldFitEast(board, anArray, posX, posY): steps = 0 while (steps < N) posX = posX + 1 if !validArrayIndex(posX, posY) or anArray[posX][posY] == 1 return false; steps = steps + 1 return true; if there is at least one direction the ship will fit, then ask which direction the user would like, otherwise, they need to pick a different location
Python 3.x runs in IDLE but has issues in Pycharm
I'm new to Stack Overflow and Python.
I've been teaching myself Python 3 for the last couple of weeks using IDLE to create my code which has been working great. I recently decided to download and install the community version of PyCharm. Here's my issue...
I've been using the import random and random.randint() command to generate numbers. When I opened my last Python project, which worked fine in IDLE, into PyCharm and tried to run it, it gave me back two errors.
When I use the "Debug" command in PyCharm, the program runs fine but when I use the "Run" function it gives me two errors.
Here's my code:
import random
# Megamillion Generator
def mega():
s = []
a = random.randint(start, finish)
b = random.randint(start, finish)
c = random.randint(start, finish)
d = random.randint(start, finish)
e = random.randint(start, finish)
s.append(a)
s.append(b)
s.append(c)
s.append(d)
s.append(e)
s.sort()
if x < 10:
print("Random ", str(i), " ", end="")
print(s)
print("Sorted ", end="")
print(end=" ")
print(s)
else:
print("Random", str(i), end="")
print(s)
s.sort()
print("Sorted ", end="")
print(end="")
print(s)
return s
# 3 digit Generator
def digit_3():
s = []
a = random.randint(0, 9)
b = random.randint(0, 9)
c = random.randint(0, 9)
s.append(a)
s.append(b)
s.append(c)
print(format, "Random {0:2}")
print((i), end="")
print(s)
s.sort()
print("Sorted", end="")
print(end=" ")
print(s)
return s
# 4 digit Generator
def digit_4():
s = []
a = random.randint(0, 9)
b = random.randint(0, 9)
c = random.randint(0, 9)
d = random.randint(0, 9)
s.append(a)
s.append(b)
s.append(c)
s.append(d)
print("Random ", end="")
print((i), end="")
print(s)
s.sort()
print("Sorted", end="")
print(end=" ")
print(s)
return s
# Begin Generator
gentype = str(input("Enter '3' for 3-digit, '4' for 4-digit, 'm' for Megamillion or 'all' for all three"))
x = int(input("Enter a number "))
x = x + 1
if gentype == '3':
for i in range(1, x):
digit_3()
elif gentype == '4':
for i in range(1, x):
digit_4()
else:
start = int(input("Enter smallest number to generate "))
finish = int(input("Enter highest number to generate "))
for i in range(1, x):
mega()
And here's the error msg:
line 1, in <module>

line 5, in <module>
a=random.randint(1,70)
AttributeError: module 'random' has no attribute 'randint'
Any Help would be greatly appreciated.
calculate fibonacci sequence position from user inserted value
Below is my full program's code:
GradeAvg = [[59, 'F'], [69, 'D'], [79, 'C'], [89, 'B'], [100, 'A']]
def letter_grade
num = number_grade
_, letter = GradeAvg.find { |n, _| num <= n }
[num, letter]
end
def number_grade
loop do
puts 'Please insert a number between 1 and 100.'
num = gets.to_i
break(num) if (1..100).cover?(num)
end
end
def fib(n)
return n if n < 2
fib(n-1) + fib(n-2)
end
10.times { print letter_grade; (num).each { |n| puts fib(n) }; puts }
It is failing with the below error:
undefined local variable or method `num' for main:Object (NameError)
Why can't I apply my fibonacci sequence calculation on my acceptable user inserted value in variable num?
You're trying to access num which is assigned in letter_grade. You must use the return value of the function call (ie num, letter = letter_grade) to read the result.
It should also be noted that Fixnum#each (ie (num).each) is not a method. 10.times { ... } already makes a loop though, so I think this was just an oversight on your part.
See the bolded section for changes. I also changed your fibonacci function to calculate in linear time (instead of exponential time)
GradeAvg = [[59, 'F'], [69, 'D'], [79, 'C'], [89, 'B'], [100, 'A']]
def number_grade
loop do
print "Please insert a number between 1 and 100."
num = gets.to_i
break(num) if (1..100).cover?(num)
end
end
def letter_grade
num = number_grade
_, letter = GradeAvg.find { |n, _| num <= n }
[num, letter]
end
def fib (n, a = 0, b = 1)
if n == 0 then
a
else
fib n - 1, b, a + b
end
end
10.times do
num, letter = letter_grade
puts letter
puts (fib num)
end
Example program execution
# Please insert a number between 1 and 100. 95
# A
# 31940434634990099905
# Please insert a number between 1 and 100. 87
# B
# 679891637638612258
# Please insert a number between 1 and 100. 77
# C
# 5527939700884757
# Please insert a number between 1 and 100. 66
# D
# 27777890035288
# Please insert a number between 1 and 100. 55
# F
# 139583862445
# Please insert a number between 1 and 100. 10
# F
# 55
# Please insert a number between 1 and 100. ...
# ...
Try like this:
GradeAvg = [[59, 'F'], [69, 'D'], [79, 'C'], [89, 'B'], [100, 'A']]
def letter_grade
#num = number_grade
_, letter = GradeAvg.find { |n, _| #num <= n }
[#num, letter]
end
def number_grade
loop do
puts 'Please insert a number between 1 and 100.'
#num = gets.to_i
break(#num) if (1..100).cover?(#num)
end
end
def fib(n)
return n if n < 2
fib(n-1) + fib(n-2)
end
10.times { print letter_grade; puts fib(#num)}
Gnome sort is faster than quick sort?
I decided to delve into sorting algorithms and implemented a few such as bubble, selection, gnome, insertion, merge and quick sort in python. However when i ran them and compared the times, gnome sort which is O(n^2) was faster than quicksort which has a O(nlogn) i believe. Question: Can someone please explain to me why my gnome sort algorithm is faster than my quick and merge sort algorithms and ways to optimize my them so that they sort faster than the less efficient algorithms. Thank you. (P.S. if you've never heard of gnome sort here's a link that will help Wikipedia Gnome Sort Algorithm)

Your sorts all mutate the input instead of returning a new list, so after the first sort, the input is sorted and stays sorted. Gnome sort is O(n) on already-sorted input.
My wxpython program suddenly doesn't work for no reason
I made a program for school few weeks ego.. i have finished it yet.
for some reason, when i am trying to run the program now, it doesn't work, although it worked well in the last time a tried.
I am sure that i didn't change anything in the code, but there is always a chance that something has changed and i didn't payed attention..
I need to pass it to my teacher in these days and i have no idea what is wrong with the program.

PLEASE NOTE:
I upgraded my windows to windows 10 few days ego, it means that it doesn't work since the upgrade if it means something. (sorry if the grammer of my english not so well, it is not my native language..).
In my computer works fine (Python 2.7.11 and windows 7). If you import this class in another file, make sure if you call the main function.
