<p>One of the most interesting innovations in the Ukraine war is their internal market place for drones, letting each drone group decide which drones they want to procure and use in battle.<p>It is not a top-down decision, production and supply  as other armies use for their weapons logistics.</p>

<p>The KISS version of regulation would be that stores are not allowed to use the word "buy" when you don't get full ownership and must use the word "license" instead.<p>Also it should be marked clearly that the company can rescind the license at any moment without giving any reason why.</p>

<p>Good trick is to prefix all such keys with magic, i.e. a couple of letters that identify type type of key.<p>Then it will always be a string and you will be free to change the format/type of the key in the future to UUID or whatever you like.</p>

<p>I'd really like a collection of unit tests for parsers.  There is a lot of details that can differ between parsers.<p>E.g. in "Section C" the resulting KeyThree is "value 3▵▵▵▵▵▵▵value 3 continued" where each "▵" symbol is a space.<p>I think most people would expect a single (or no) space here.<p>I would guess that most software would strip the comments in SectionC or rearrange the output so that it will result in a diff even when nothing in SectionC changed.<p>So if you edit the file by hand in the same style as shown in the examples, then most editors would not be able to make a minor edit without making a large diff as many sections would be formatted differently.</p>

<p>It's a very different world from the exams I had in Denmark, both uni and high school:<p>* all exams were proctored<p>* the proctoring were done by external people hired to do this.<p>* you could not leave exam for the toilet without asking first and then being followed out by a watcher, which then would follow you back and check the toilet afterwards for notes.<p>* you were never handed back the papers you handed in.<p>* responses were judged both by your own teacher and by an independent teacher from another institution.<p>* you must use ballpoint pen (permanent) and not pencil.  Pencil responses were ignored.<p>Today the studens are even handed Faraday-bags that their phones and smart watches must be kept in during the exam.
