Better way to shuffle two numpy arrays in unison
...17., 4., 5.]])
Now we create views simulating the original a and b:
a2 = c[:, :a.size//len(a)].reshape(a.shape)
b2 = c[:, a.size//len(a):].reshape(b.shape)
The data of a2 and b2 is shared with c. To shuffle both arrays simultaneously, use numpy.random.shuffle(c).
In production code, you w...
How to compare versions in Ruby?

I would do
a1 = v1.split('.').map{|s|s.to_i}
a2 = v2.split('.').map{|s|s.to_i}
Then you can do
a1 <=> a2
(and probably all the other "usual" comparisons).
...and if you want a < or > test, you can do e.g.
(a1 <=> a2) < 0
or do some more fu...
