It's not rocket science, but "trivial" is very harsh. This stuff is fiddly to get right. The author (who I assume is a student) seems to have done a good job and it's a nice writeup.
The results are just some particles in an extremely basic pattern, there isn't a lot of payoff.
What it was meant to show is that V8 is *good enough* to even consider it for the job :)
Do you really not think this is a mistake? Most people would see C getting outperformed and realize there is something wrong. I'm shocked anyone would both this then try to rationalize it after.
Also if someone wants to put their first CS project on the internet, then label it that way and not as some sort of blog post about them doing something unique.
