It's so interesting how I feel the same way about where I live now... and even more interesting that every time I visit the US, people seem happier there than anywhere I've been before.
For anyone wondering, Gustavo runs https://pikuma.com/ which has a host of lectures on a variety of topics from PlayStation 1 programming to maths to triangle rasterisation.
Hey! Gustavo here. Thanks for the mention. The 3D software renderer course is still one of my favorites, even though it was one of the first ones I've published. I recently re-recorded the chapter on perspective projection matrix.
That reminds me of an old comic where a guy picks a milk carton from the grocery store shelf and reads in the box: "Now with 0.01% less semen." and he does not know if he's happy or sad about it.
Check the ID numbers (48410844 < 48424862) and bear in mind that Hacker News has this thing where sometimes submissions get re-cycled for attention. Yes, annoyingly it does seem to make the presented datestamps wrong.
People submit a lot of stuff all the time, very few people go through "New" and thus a new submission probably have a very short life time before it is drowned by newer submissions.
A submission to survive most likely needs some initial push from non-organic voting.
It probably helps if you share you submission early with your colleagues and in other sites.
I've had this experience a few times so I don't post submissions anymore either (including one of my own articles being flagged despite over a hundred comments). I know people will say vote rigging doesn't happen on HN, but I think it's naïve to think any site on the internet is impervious to vote rigging.
I think it's worth mentioning Gustavo Pezzi's lectures at pikuma.com. The one on "Digital Electronics" and the one on "Interpreters & Compilers" really helped me.
