Compile with: gcc -std=gnu11 -o "portknock" "portknock.c" -lpcap
I did this as a learning experience, and it actually ended up being something useful. I made a port-knocking spawned reverse TTY with it, and it could easily be made into a port knocking firewall daemon.

This is my first try with Java. AWS Client is an open source GUI application to monitor and ssh into EC2s, and probably will expand to more services.
Can I get code review for this application?

Funny you mention create more content - that was exactly my CommunityBuilding.SE answer to How do I start an active userbase for...
I have some MATLAB code that computes the curvature of a 2d image. It computes it iteratively using forward and backward differences. Could you offer some tips for how I can optimize this code?

By HD I mean hard drive.
I am a self-taught programmer and would like anyone to point out anything that is not the standard or professional way to do things. Any help/advice is greatly appreciated.
I would love to post a lot of my code or perhaps make a youtube video explaining certain portions...
Please,can anyone provide me the code for this program..
Though, the code that I made works perfectly fine. I'm wondering whether there is a better and less chunkier way of doing this.
$(document).ready(function () {
var item1 = "active";
var item2 = "unactive";
var item3 = "unactive";
var item4 = "unact...
I have code which looks something like this (with comments indicating the irrelevant parts which I've snipped for brevity):

Sonar/FxCop are telling us that we shouldn't use void async methods. That's ok.
This is the current implementation:
private async void InitMethod(ServiceControl serviceControl)
{
if (serviceControl != null)
{
await Task.Factory.StartNew(() => serviceControl.Execute());
}
}
...
well this is my code:
fct 1 a b = a+b
fct 3 a b = a+b
fct 8 a b = a+b
fct x a b = a-b `for the rest : 2,4,5,6,7,9..16`
My question is, is there a way to combine the 3 first lines, as they do the same thing, something like "case x of" ? but with multiple values. Any help will be appreciated
During a code review I have seen the following line within a controller:

The D programming language is an object-oriented, imperative, multi-paradigm system programming language created by Walter Bright of Digital Mars and released in 2001. Bright was joined in the design and development effort in 2006 by Andrei Alexandrescu. Though it originated as a re-engineering of C++, D is a distinct language, having redesigned some core C++ features while also taking inspiration from other languages, notably Java, Python, Ruby, C#, and Eiffel.
D's design goals attempt to combine the performance and safety of compiled languages with the expressive power of modern dynamic languages...
