Seems we have some language features not fully documented (like bitshift operators in #1322).

Would be good to go through language grammar and make sure everything is in the reference guide.

Currently we have just one type of docs which are "reference" documentation. We should add a "how-to/tutorials" section with goal-driven content. We can start by drawing already available content:

At the moment of writing this issue, kubectl trace only supports X86-64 as target architecture.

The tool should be able to schedule bpftrace programs against all the architectures supported by bpftrace, that are X86-64 and arm64 (aarch64) see the Cmake definition.

To achieve that we n

Current situation

When users want to restart the Inspektor Gadget, they have to run:

kubectl gadget undeploy
kubectl wait --for=delete namespace gadget --timeout=-1s
kubectl gadget deploy | kubectl apply -f -

Ideal future situation

Users do not have to manually wait for the namespace to get deleted but it is embedded in the undeploy command.

Implementatio

Given this solidity:

contract C {
	function foo(int a) public {}
	function foo(int a, int b) public {}
	function foo(int a, int b, int c) public {}
	function bar() public {
		foo(true);
	}
	function bar2() public {
		foo({a:true});
	}
}

The error message you get is:

/home/sean/git/solang/overloaded.sol:6:3-12: error: cannot find overloaded function which matches signa

Short Description

Currently, the GRPC server port [is a configuration](https://github.com/kubearmor/KubeArmor/blob/bf39613c0c01e986d3e77d2f46a59c526cbf5907/KubeArmor/config/config.go#L79) and the default value is 32767.

Can we get some performance comparison between polycube and using standard linux facilities (NAT, iptables, etc.)?

CPU usage, PPS, latencies, etc.

https://github.com/aquasecurity/libbpfgo/blob/main/helpers/osinfo.go seems to be untested. It would be helpful to add some unit tests to cover certain scenarios.
