Why aren't two files that should be equal not equal? I download a file with Java Socket, and compare it with the same fi

I wish this helpful for you When you connect with a raw socket, you are going to get HTTP headers, that you need to parse, and not save into the output file. The real data starts after you see two newlines in a row, indicating the end of the headers. You should be reading Contentlength from the headers, not hardcoding. If you open up your downloaded file (the one you made by using Socket), you'll see those HTTP headers.

matplotlib (equal unit length): with 'equal' aspect ratio zaxis is not equal to x and y

wish of those help I believe matplotlib does not yet set correctly equal axis in 3D... But I found a trick some times ago (I don't remember where) that I've adapted using it. The concept is to create a fake cubic bounding box around your data. You can test it with the following code: code :
from mpl_toolkits.mplot3d import Axes3D
from matplotlib import cm
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_aspect('equal')
X = np.random.rand(100)*10+5
Y = np.random.rand(100)*5+2.5
Z = np.random.rand(100)*50+25
scat = ax.scatter(X, Y, Z)
# Create cubic bounding box to simulate equal aspect ratio
max_range = np.array([X.max()X.min(), Y.max()Y.min(), Z.max()Z.min()]).max()
Xb = 0.5*max_range*np.mgrid[1:2:2,1:2:2,1:2:2][0].flatten() + 0.5*(X.max()+X.min())
Yb = 0.5*max_range*np.mgrid[1:2:2,1:2:2,1:2:2][1].flatten() + 0.5*(Y.max()+Y.min())
Zb = 0.5*max_range*np.mgrid[1:2:2,1:2:2,1:2:2][2].flatten() + 0.5*(Z.max()+Z.min())
# Comment or uncomment following both lines to test the fake bounding box:
for xb, yb, zb in zip(Xb, Yb, Zb):
ax.plot([xb], [yb], [zb], 'w')
plt.grid()
plt.show()

R sample probabilities: Default is equal weight; why does specifying equal weights cause different values to be returned

Hope this helps As suggested by Randy, different routines are used by sample.int depending on whether prop is NULL. In your case, it returns inverse results: code :
> set.seed(1); sample(c(0,1), size=20, replace=TRUE)
[1] 0 0 1 1 0 1 1 1 1 0 0 0 1 0 1 0 1 1 0 1
> set.seed(1); sample(c(0,1), size=20, replace=TRUE, prob=c(.5,.5))
[1] 1 1 0 0 1 0 0 0 0 1 1 1 0 1 0 1 0 0 1 0
for (int i = 0; i < k; i++) iy[i] = (int)(dn * unif_rand() + 1);
/* compute the sample */
for (i = 0; i < nans; i++) {
rU = unif_rand();
for (j = 0; j < nm1; j++) {
if (rU <= p[j])
break;
}
ans[i] = perm[j];
}
do.call(cbind, lapply(c(1:10),function(X) {set.seed(X); sapply(vn, function(Y) sum(sample(x=c(1,0),size=Y,replace=T, prob=c(0.5,0.5))), simplify=TRUE)}))

I need to find out if two lists are equal in terms of reference, equal in terms of value or not equal

Hope that helps You should check if list1 is list2 before you check for equality. When x is y, x always equals y.

How to make condtiion if string not equal to null and greater than equal to 10 and less than equal to 1000?

wish helps you Change your if statement. Your question says you want to check condition 1 and 2 and 3 but you have done is OR() code :
if ((m_szAmount.length()!=0 && Integer.parseInt(m_szAmount)>=10 && Integer.parseInt(m_szAmount)<=1000) && (m_operatorSpinner.getSelectedItemPosition() > 0 && m_circleSpinner.getSelectedItemPosition() > 0)) {
m_SubmitButton.setEnabled(true);
}
