...
Jon, I'm sorry, I read your answer many times trying to figure out what you mean and where the "J c" solution does not use the same delegate to subscribe and unsubscribe, but I can't fint it. Pehaps you can point me on an article that explain what you are saying ? ...
#include in .h or .c / .cpp?
... @BrendanLong I see, although in my sense including several times a same header doesn't matter if you put the correct macros inside to include the content only once. Therefore, I think that putting even less is to reduce probabilities to get an error in the future with modifications o...
What's the difference between passing by reference vs. passing by value?
...n 1975, Barbara Liskov suggested the term "call-by-object-sharing" (or sometimes just "call-by-sharing") though it never quite caught on. Moreover, neither of these phrases draws a parallel with the original pair. No wonder the old terms ended up being reused in the absense of anything better, leadi...

Matplotlib discrete colorbar
...at color (not to any color).
It is not complicated but as it took me some time, it might help others not lossing as much time as I did :)
import matplotlib
from matplotlib.colors import ListedColormap
# Let's design a dummy land use field
A = np.reshape([7,2,13,7,2,2], (2,3))
vals = np.unique(A)

Increasing the maximum number of TCP/IP connections in Linux
...he client side:
Increase the ephermal port range, and decrease the tcp_fin_timeout
To find out the default values:
sysctl net.ipv4.ip_local_port_range
sysctl net.ipv4.tcp_fin_timeout
The ephermal port range defines the maximum number of outbound sockets a host can create from a particular I.P. a...
'AND' vs '&&' as operator
...our code. If you do the same on a compiled language it only will take more time to compile but it will not take effect on runtime. I don't mean doing it once will mark a difference but on an entire application using php + javascript both wrote like the example... load times will be larger for sure. ...
Change date of git tag (or GitHub Release based on it)
...tated tags.
Summary
For each tag that needs to be changed:
Go back in time to the commit representing the tag
Delete the tag (locally and remotely)
This will turn your "Release" on GitHub into a Draft that you can later delete.
Re-add the same-named tag using a magic invocation that sets its...
Why doesn't this code simply print letters A to Z?
... 'z'+1 ≤ 'z'. (Since 'z'+1 = 'aa' ≤ 'z'. But 'za' ≤ 'z' is the first time the comparison is false.) Breaking when $i == 'z' would work, for instance.
Example here.
