A peer to peer file system sharing application with GUI in browser

While my knowledge of IPFS is pretty basic, this strikes me as a great use case for it. IPFS ( https://ipfs.io ) is a P2P internet protocol that's made to enable a decentralized internet...I believe its goal is to supplant (or at least supplement) HTTP(S). As I said, my knowledge of IPFS is still pretty basic, but I find it fascinating and I thought it might be relevant for this application.

I am probably wrong but my understanding is that IPFS is an addressing scheme. While it can be private or peer to peer it can also be public. As an addressing scheme it continues to follow the web’s client-server model. A client-server model on the web is inherently public and anonymous.

A dedicated peer to peer system focused on privacy has no server and no third party. Instead the model is client-client without third party routing. Privacy is then achieved because connections are direct, in an application layer sense, between nodes and each node is a client running the same application in the same way. This is always confidential and never anonymous. This is achieved because there is no application layer addressing used at all, not even DNS.

Think about it more in terms of a shared disk drive on a private network mapped to a local file system address instead of a web location.

Launched my audio plugins in July, averaged about $1k/month in sales (no idea if this is good or bad). https://bomshankamachin.es

I made it easier to opt out of data sharing that no one would have opted in to: https://simpleoptout.com/

Lots of people have. There's now some consequences for customer-unfriendly data sharing policies, too: someone will notice and you'll get negative press. It was recently in the NY Times: https://www.nytimes.com/2019/11/24/smarter-living/privacy-on...

An interactive map of internet, or ipv4 block viewer: https://ipv4.dev.sarl/

This is really well done. FYI, in Firefox on macOS, the search box doesn't seem to do anything for me. I don't see any outputs or requests in the JS console or network tab.

I just released my first product (https://www.keepmeon.top). It fetches and filters content from Reddit, Hacker News, Lobsters, etc. and generates a RSS feed or sends a periodic email summary.

There are a lot of things to improve, but it's a start...

I also made a little game using TypeScript: https://xojoc.pw/games2d/4snakes/

I built a prototype of an ingredient list scanner for Keto people. It's still not launched and I'm sure there's bugs, but I'm hoping that posting this gives me some motivation. :-) https://ketoscanner.site/beta

I had this same exact idea a few years ago. Thanks for creating it!

We built a lot, but here are two :) Talkative (meettalkative.com) - The easier way to interview your users Referlist (referlist.co) - Increase sign-ups via Robinhood-style referrals

looks cool, wish it linked to other mailing list providers like SendGrid or Drip, Mailchimp has some really bad policies and I won't use them anymore.

That's awesome! I've always thought the idea of programming VSTs/VSTIs was interesting.

Can you link to any resources you used in learning to build them?

The biggest thing I have built this year is Hexadecimal ( https://tryhexadecimal.com ). It is my first SaaS business, so it is a pretty rough endeavor, both on the development and the business side. Built on the vanilla Rails stack. As boring as it could possibly get. I have described in some detail the tech behind it: https://runninginproduction.com/interviews/9-running-a-websi... Lessons learned: * If you'd like to…

If not SaaS, then what?
