What is the memory consumption of an object in Java?
...r 32-bit JVMs, the overhead is 8 bytes, padded to a multiple of 4 bytes. (From Dmitry Spikhalskiy's answer, Jayen's answer, and JavaWorld.)
Typically, references are 4 bytes on 32bit platforms or on 64bit platforms up to -Xmx32G; and 8 bytes above 32Gb (-Xmx32G). (See compressed object references...

python plot normal distribution
...could come up with is:
import numpy as np
import matplotlib.pyplot as plt
from scipy.stats import norm
# Plot between -10 and 10 with .001 steps.
x_axis = np.arange(-10, 10, 0.001)
# Mean = 0, SD = 2.
plt.plot(x_axis, norm.pdf(x_axis,0,2))
plt.show()

Simple tool to 'accept theirs' or 'accept mine' on a whole file using git
...tion is very simple. git checkout <filename> tries to check out file from the index, and therefore fails on merge.
What you need to do is (i.e. checkout a commit):
To checkout your own version you can use one of:
