Tell HN: a Google Chrome extension which highlights hot links on HN (madk.org)
23 points by btw0 on May 29, 2010 | hide | past | favorite | 9 comments


Kinda nice... makes it easier to find the popular items after they've fallen off the top of HN, and faster to skim (which I should do more of anyway, I waste too much time here).

The hotness calculation seems to be pretty basic, just grabbing the points / comments numbers on the page and comparing them to each other. Which is actually exactly what I want, I'm not really interested in something which tells me exactly what HN's sorting equation tells me, and more complex == harder to understand the results.

Found a bug, btw: upvoting gives me NaN instead of a number for points.


How do you work out what's hot, if you don't mind me asking? Something based on the points, comments and time I'm guessing?


Yeah, it's in the screenshots. Cute little utility.

suggestion: maintain a local cache of usernames I frequently upvote/downvote/ reply to/whose links I click. Special highlight for threads in which I have already commented or in which my top X posters are participants.


Screenshot doesn't really tell me how it calculates hotness. HN already uses some form of hotness based on points/time, but this uses a different formula I think.


It looks like it simply uses the number of comments for highlighting comments links, and the number of points to highlight points counters.


Yeah seems that way, I just saw two comments with the same number of points but significantly different posting times and they have the same color. Thought time might be factored in too, like HN does points/(time since submitted)^2.

Also noticed that it doesn't differentiate between positive and negative scores. A score of -4 is hotter than a score of 1.


Thanks! You just found me a bug, I am going to fix it :)


Cool. Is there a firefox version?


Sorry, currently it's only a Chrome extension. Maybe I'll port it to firefox when I have time.
