There are laws requiring discrimination based on vaccination status and have been for your entire life.

Please. There is a tiny, tiny minority of people who actually object to vaccinations on religious grounds. This is an excuse.
I found it jaw-dropping how badly Microsoft handled that release. In some cases, the best way to improve multithreaded performance under Windows was to disable three quarters of the cores. Meanwhile any decent Linux distro scaled to the full core count out of the box.
I wonder to what extent this is holding back computer architecture. Certainly the Wintel cartel has historically back competition from other architectures, but even within x86-land we can see the monopoly power and technical inadequacy of Windows holding back innovation.
Linux supports every architecture known to man. Microsoft pretty much only supports x86. They have no excuse.
The professor gave the students incomplete information. What they said is perfectly reasonable. This is a project they will be doing on their own time, so the scope of it is entirely up to them.

You can think compulsory vaccinations are wrong, but there were compulsory vaccinations ten years ago. It has always been difficult for antivaxxers to find work, particularly in healthcare or education.
Modern hardware can and should last ten years. Accept no excuses.
We can debate the Correct Implementation all day long. The fact of the matter is that adding any index to the original table, even the wrong index, would lead to a massive speedup. We can debate 2x or 5x speedups from compression or from choosing a different schema or a different index, but we get 10,000x from adding any index at all.
