Dealing elements

There's a function in clojure.core called partition-all. It creates subsequences of a given maximum size.

(partition-all 3 [1 2 3 4 5 6 7 8]);=> [[1 2 3] [4 5 6] [7 8]]

Notice that the first sequence gets the first three elements, the second sequence gets the second three elements, etc. We could get the original sequence again by concatenating the sequences back together.

You should not use the Open SSH client that comes with Git for Windows. Instead, Windows 10 has its own implementation of Open SSH that is integrated with the system. To achieve this:

1. Start the ssh-agent from Windows Services:

• Type Services in the Start Menu or Win+R and then type services.msc to launch the Services window;
• Find the OpenSSH Authentication Agent in the list and double click on it;
• In the OpenSSH Authentication Agent Properties window that appears, choose Automatic from the Startup type: dropdown and click Start from Service status:. Make sure it now says Service status: Running.

2. Configure Git to use the Windows 10 implementation of OpenSSH by issuing the following command in Powershell:

git config --global core.sshCommand C:/Windows/System32/OpenSSH/ssh.exe

HashSet that preserves insertion order or .NET implementation of LinkedHashSet

Many people naively assume an ordinary .NET HashSet preserves insertion order. Indeed HashSet accidentally preserves insertion order until you remove and re-add some elements. There is such a data structure in Java - LinkedHashSet which respects order and has O(1) RW times.

No, I did not find a (working) corresponding implementation in .NET. That's I wrote this one.

The implementation uses linked list in combination with dictionary to define the iteration, ordering and at the same time allow O(1) removal.

The order is not affected if an element is re-inserted into the set it retains it's old position.
