Can we please make this a recurring question Wouldn't it be worth doing a trial period of manual posts first, to gauge the amount of interest?

Agreed, and can we please not make this a thing, actually? Because it happens regularly already and in my opinion it's pretty noisy. We have questions like: "What is your pain point?" "What do you wish existed?" "What problem in your industry would you pay to solve?" "What is your side project?" "How much do you earn from your side project each month?" It just seems obsessive. There is sometimes a fair amount of part…

This is radically different to the above questions (which you may not find personally useful, but to the more bootstrap/entrepreneurially minded HNers are often pretty helpful or interesting.)

They are general information/discussion posts.

This post's a direct service connecting HNers with assets to HNers who want to buy them. Assuming there are a reasonable number of both, and the replies in the thread so far suggest there are, it's useful to have it recur for the same reason that "Who's Hiring?" is useful.

As for your question on whether anyone's ever bought a side project from a thread like this - the comments on this thread alone suggest there's a fair bit of interest in purchasing side projects, at least.

https://pricemoji.com/ an GraphQL/Node.js API that turns product prices into emojis.

No revenue, just a side project really. But considering the feedback I'm often getting, it seems to have great potential...

Originally, my challenge was to find a way to turn abstract product prices into more familiar, visual representations of their worth. Imagine paying your Netflix subscription in Bananas for example :)

A Financial Times journalist dubbed it a way to "take us back to a barter economy, where we price things in emoji beer rather than dollars".

Been featured on Product Hunt at producthunt.com/posts/pricemoji as well.

Would be curious to hear for your proposal for such an app? I was thinking $15K or something.

Thanks! They are different sources, I use OpenDota's open source software to gather matches and dump them into Google's BigQuery for processing using our own algorithms we've created. The algorithms are run against 15 to 30 million matches depending on how deep in the patch is. My guess is we've landed on similar algorithms to DotaPicker, it's usually the set of matches we're using that makes the difference so I'm su…

Are you partitioning the matches by MMR, or just doing global suggestions? I ask because this always seems the biggest weakness of all the existing picking tools. A 1k player and a 5k player throwing the same lineup into a picking tool should ideally get dramatically different suggestions, both because of their own skill and the skill of their teammates.

There is no access to MMR from the Steam API. Best we have is Normal, High, and Very High skill splits and the problem then becomes having a large enough sample size to have accurate results.

114 heroes that all influence each other when they play together so if you're looking at matchups for two heroes that don't get played frequently the accuracy is already limited.

That said, my strength is in front end, not statistics. Getting a Normal and High split might be fine as is.

I built 'h34t' - shows a realtime heatmap of where people are in the city (search iTunes Store for it). Snapchat just paid $300 million for the same functionality. They could've bought it from me for a lot less ;)

Your app shows that nothing happening neither in San Jose nor in SF? iPhone 7+.

Maybe that forced Snapchat to spend more money? :)

The filter is set to show activity in the last month only - slide the filter to all and you'll see activity.

The app has gone a bit into hibernation lately, so the activity has waned.

Thx for checking it out though!

How do you do it?

Not sure what you mean by the question?

I built the full stack by hand. The iOS is Obj-C and the backend is NodeJS/MySQL.

Basically, the MySQL DB has checkin data (provided by users or from social media networks) pivoted on metadata (male, female, age) and then passed to a custom visualization algorithm on the mobile device.

Happy to answer any other questions.

True, but the OpenDOTA API does give access to estimated MMR stats for many games, which are pretty accurate. So you could use those if you wanted to.

That would limit the available match pool, granted. It depends on how many thousand games you need to make predictions, I suppose. I was able to pull some interesting data a while back from the 2k pool but I wasn't trying to solve as hard a problem as a global hero picker.

They do, but they don't allow sequential pulling of match data.

I would have to collect my own data and poll their API with each match id to get the MMR estimate.

Although that works in theory, their API rate limit is 3/s and last time I checked there were about 1M matches / day (~12/s) so we couldn't keep up.
