Ask HN: Realtime app ideas for side project?

40 points by mbm ↗ HN
What are some ideas for apps that could be built to become more conversant with near-realtime technologies à la Storm, Kafka, Spark Streaming and the like?

Let's define realtime not as financial index realtime but as responding very quickly to a potentially large number of input events which will be coming in over a network.

Analyze how a Trump tweet affects stock prices, twitter sentiment, major news outlets in real time

That's very cool! Perhaps the "Trump bump" could be quantified.

Yes. Sounds like you'll have to deal with getting the data from different sources (either by crawling or APIs) hopefully in a distributed manner (storm, for example) and then analyze the inputs using something like spark or hadoop. If you like, let me know if you end up building it. Email in profile.

Could be an interesting experiment on Quantopian.

twitter should just tape delay his tweets and invest or short just before...
bbcbasic
would be cool if twitter shorted itself

An app that collects app ideas for the best realtime app idea and shows the aggregation of ideas on a webpage

And it does it all -- get this -- in realtime.

Which, even funnier, are all very, very removed from the actual technical meaning of realtime to the point where they make a mockery of the concept.

Or a chatroom for HN in general.

It's best to learn what real-time actually means in the context of technology. None of the above technologies are real-time. Near-real time might be more accurate but it depends on your tolerance.

It's best to understand that language evolves over time and despite the fact that "real-time" has had a specific meaning in the context of software for quite some time, it now has another meaning, under which all of the above technologies are real-time. Enjoy.

I don't think the term real-time has changed. Some people misuse it but it's still a very well-defined and strict term.

curious on what context do you mean by real time?

Likely that he means real-time OS kind of real-time. Like robotic vision; time-critical embedded software.

Realtime new stuff on Netflix for series junkies.

A social network for people drinking the same beverage right now.

You could have rooms for particular regional coffees or more simple like hot chocolate or commercialized like one for Budweiser.

There could be content you unlock by proving you're drinking a certain drink.

Listening to the same music right now.

Playing the same YT video right now.

Social networking are best way for side project

I wad amazed by the youtube videos with the new capabilities of drones and hardware configurations.They also plan to deliver internet by drones if networking is what you are into.

I got this idea of using my twitter follower graph and extracting out entities like movies, restaurants, books and people they talk about.

I have noticed that I end up eating at places, go to coffee shops, read book and watch movies/shows people I follow talk about. If there was a simpler way to browse that, it might be useful.
