Looks cool! And the header image looks awesome! Did you use any tool to do it?


Thanks! Not really, just basic vector shapes and an isometric projection grid to make sure perspective is right.


I just started a project in NestJS. Prior to this I was working on express for NodeJS backend where I had to do a lot of manual stuff and achieving dependency injection across the application was a pain. I'm impressed with NestJS so far. If I could go back in time and re-work the project, I'd choose NestJS. I've also worked with Rails and Spring boot. With NestJS I get the same ease and flexibility like in Rails and Spring boot.

Finally a great web application framework for NodeJS.


How does YC feel about funding on AR, VR and mobile games technology?


He wrote about VR two months ago: https://blog.ycombinator.com/vr/

> Recently I’ve heard a lot of investors say “There isn’t a whole lot of new stuff to do in consumer. There’s already an app for that.” With VR, there isn’t already an app for that.

> I think we are no more than two years away from an explosion of new consumer startups and I cannot wait to start funding them at YC.



How did you do this? What tech stack do you use?


Ruby on Rails for the backend, Angular on the front. It's hosted on Heroku, it uses cloudfront, S3 for storage, Postgres for DB along with httpClient and mechanize for crawling and Paperclip for image manipulation.


Do you use any kinda algorithm for crawling/fetching content from reddit?


Not particularly. The one thing that helps but most people don't know about reddit is the fact that adding a .json to the end of each url displays the content of that page in json format.

for example: reddit.com/r/funny.json

This make crawling/fetching content from reddit much more trivial than old school web crawling.


Anybody know why the first approach to Mars is 20 light minutes? Musk mentioned that the fastest approach to Mars is 4 light minutes!


Earth is 8 light minutes from the sun, Mars is 12 light minutes from the sun. So when Earth and Mars are closest to each other, they're 4 light minutes away from each other, and when they're farthest from each other (on opposite sides of the sun), they're 20 light minutes away from each other.
