There is no advantage to it = iter(iterable) in the code shown and that line should be removed. max calls iter() (or the C equivalent) on the first argument making the original call completely redundant.

There are cases where it is useful, such as an iterator that is only partially consumed in several steps. In a wildly contrived example, you may want the first value and then everything after 3. This demonstrates using next to get a value, a for loop to consume more and finally passing to another function/class to consume whatever is left over. Note that next would raise StopIteration if there were no values, but the other two work fine even if the iterator has been exhausted.

Use language injections (from Alt+Enter intention actions menu) to inject Shell script and Python into the code fragments:

You can pass a pointer to your sockaddr structure in SYS_RECVFROM according to the documentation here:

Since the file are read sequentially, after a call to sys_read in append mode the curso is moved to the end of the file, so if you try to erad from that position you want read anything.

To solve this problem you have to reposition the cursor at the beginning of the file.

To do that you can use the lseek system call.

I've added a repo that shows you how to do this. From the README.md:

Requirements

Generally speaking, using libraries targeting .NET Standard in an application targeting .NET Framework requires the application project to include a NuGet reference for .NET Standard (NETStandard.Library). This ensures that the right set of assemblies are included with the application.

In Visual Studio 2015, the default way of consuming NuGet packages from .NET Framework projects is via packages.config. I don't recommend this path as this means that all assemblies are directly injected into the application project, which will significantly bloat your project file. Instead, I recommend you use project.json. To do this, perform the following steps:

1. Uninstall all packages (if you're still using packages.config)
2. Delete the empty packages.config

3. Add project.json file with this content:

   json { "dependencies": { "NETStandard.Library": "1.6.0" }, "runtimes": { "win": {} }, "frameworks": { "net462": {} } }

Please note that you can generally depend on the latest version of the NETStandard.Library package, but you need to make sure to keep the framework moniker in sync with the version of .NET Framework your app is targeting, i.e. when you're targeting .NET Framework 4.6.1, you need to make sure to use net461 instead.

This feels clumsy

Yes it is. We're planning on addressing this in two ways:

• We're replacing project.json with an MSBuild based solution in Visual Studio 2017. You'll still need to add the reference to NETStandard.Library, but you no longer have to mess with the way packages are being represented nor having to manually keep targeting information in sync.

• We're planning to update .NET Framework so that future version of it come with built-in support for .NET Standard, in which case the reference will no longer be needed.
