Can you please not be a jerk in HN comments and especially not in Show HN threads? There are special rules for Show HNs: https://news.ycombinator.com/showhn.html.

Keep in mind that not everyone sharing their work here is a grizzled veteran. Some are enthusiastic people learning to do something for the first time. The community here should welcome such users, not beat up on them, which is the effect that a comment like yours can have (though I'm sure it was not your intent).
