A few months ago, I came across a personal blog here on HN with the main feature being about ~4 sliders that change the weights of all posts and rank them in real time. I think some of the sliders were for "popularity", "recency" and perhaps "author's score". I also think, but I'm not sure, that the blog featured general ML topics.

I played with the sliders for sometime and had a great time exploring the blog, but I have since failed to find it again. I should've bookmark it then.

Does anyone have some clue about it? Much appreciated
