Do HttpClient and HttpClientHandler have to be disposed between requests?
... Console.ReadKey();
}
}
}
With this new understanding, now we revisit that blog post,
we can clearly notice that the "fix" initializes HttpClient once but never dispose it,
that is why we can see from its netstat output that,
the connection remains at ESTABLISHED state which mean...

Add a duration to a moment (moment.js)
...d compare those, or you could just use the .isSame() method.
Your code is now:
var timestring1 = "2013-05-09T00:00:00Z";
var timestring2 = "2013-05-09T02:00:00Z";
var startdate = moment(timestring1);
var expected_enddate = moment(timestring2);
var returned_endate = moment(startdate).add(2, 'hours'...
Set every cell in matrix to 0 if that row or column contains a 0
...in the size of the matrix.
I use 1rst column and first row as markers to know where are rows/cols with only 1's. Then, there are 2 variables l and c to remember if 1rst row/column are all 1's also.
So the first pass sets the markers and resets the rest to 0's.
The second pass sets 1 in places wher...

For example:

What is the global interpreter lock (GIL) in CPython?

It still amazes me that to take advantage of a 32-core server with Python means I need 32 processes wi...
List comprehension on a nested list?
...s actually same as :
New_list=[]
for x in l:
New_list.append(x)
And now nested list comprehension :
[[float(y) for y in x] for x in l]

new_list=[]
for x in l:
sub_list=[]
for y in x:
sub_list.append(float(y))
new_list.append(sub_list)
print(new_list)

How can I default a parameter to Guid.Empty in C#?
...defined as static readonly not as const). Compiler can only have compiler-known values as method parameters default values (not runtime-only-known).
The root cause is that you cannot have a const of any struct, unlike enum for example. If you try it, it will not compile.
The reason once more is th...
