    Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

    So, you want to avoid mass surveillance and don't trust big tech companies either? But you're tied to your existing network of contacts like everyone else?

    Hey HN! I made a service to share passwords easy and secure but never promoted it. It's called instapass.io I noticed that people besides my friends and clients actually started to use, so maybe it will be helpful for you too! You share one-time self-destruct message using one time links and I won't even be able to see what you wrote. How does it work? When you generate a message the client-side makes a random password and use that to encrypt the message. The password is appended as an anchor tag which all modern browsers never send to the server. This way, I don't even know what you shared.…

    For the past couple of months, I’ve been working with a total stranger, @ahmetsulek. We’ve never met in real life, and our communication has been restricted to Skype. And that’s Skype call, not video. Whilst it’s advised that one should only team up with somebody they’ve known for a long time, I’ve found this not to be necessary. Instead, all you need is a dose of mutual respect and a clear partnership agreement. We’ve been working together for the past couple of months on a web app and Chrome Extension that aggregates sites like Hacker News, Designer News, Sidebar.io, Behance and Dribbble…
