I'd just like to remind everyone to say thank you to your God of choice, or otherwise to the universe. Say thank you for everything you have, as somewhere in the world there are people who don't. It's not difficult to say thank you (except for some people), yet it makes one reflect and adds some humility to one's life. Again, it doesn't matter who you say thank you to. I personally thank the universe when I wake up, go to sleep and a few more times each day. It's free.

Remember to say thank you. Really, write it down.

The Rocketbook is a lineup of erasable notebooks made to be reusable for years and then some. I bought one a few days ago and now use it for most note-taking, so here's a short introduction.

The story goes as follows: co-founder of Rocketbook Joe Lemay forgets to pack the correct notebook for an important sales meeting at Salesforce. Looking for a solution to this problem he tried out electronic pens and smart notebooks, but it doesn't feel quite right. So he creates something that does feel right. A few products and crowdfundings later, we now have the Rocketbook Everlast:

Rocketbook Everlast

It is really a notebook of this day and age: made of synthetic paper, the pages can be erased. Coupled with the Rocketbook app, I can save a scan of my notes on my phone before erasing a page. The fact that it doesn't force you to send your pages to the cloud is a plus, but you don't really have to use their app. I personally use an app called Notebook to scan my pages, then send them to Nextcloud so I can correctly categorize the files on my computer later.

Writing on the Rocketbook feels very different from writing on paper. The pages don't have any granularity and my pen just slides over them. It takes a bit of time to get used to, but otherwise writes just as well. It's also worth noting that erasing using the FriXion eraser doesn't seem to work well. You have to erase using a damp cloth. While we're at the disadvantages, the front and back cover seem to scratch very easily. After handling the notebook for a few minutes the covers already had deep scratches in them. Although annoying, I wouldn't call this a deal breaker.

The Rocketbook Everlast is just one of the available notebook formats: it also exists in a smaller size, as well as with different page style combinations. Something to please everybody :)

All-in-all, after using it for a few hours, I'm already a customer for life.

You can’t propose that something be a universal space and at the same time keep control of it. - Tim Berners Lee, Inventor of WWW

Over the last few years, we've seen the rise of mega corporations that have had a significant impact on our lives. They've made our lives easy, they've given us platforms to use that help us connect with the rest of the world with a few taps on our devices, they've provided you with means to watch cat videos for free. Are all these really free? To use a cliché, “If something on the internet is free, you are the product.”

The Problem

If you are someone who has wondered how texting our friend on Zucky's phone number based messaging app has resulted in ads being served to us about it on the blue F platform, chances are that we have also figured out that it's no coincidence. They are tracking everything we say, type, browse, listen etc. And with so much data about us, they can predict who we are just by matching some parts of our real life signature which depends on these tastes.

The algorithms at these corporations also amplify content that are eye catching, controversial, rage inducing etc so as to have all of us going back for more, and engaging with them so that they can tell their investors that they are generating traffic and get more cash inflow. They also decide what we are thinking about at every moment in time we spend time on their platforms.

Then there's the issue of censorship, and partiality from these corporations that results in folks making legitimate cases being banned, yet inflammatory personnel and trolls who incite the masses with immoral speech are allowed to roam freely in the name of “free speech”.

All this means is that we aren't in control of what we want to see, we don't get to decide what's done with our data, we are left at the whims of these corporations who decide how the internet should be.

The Solution

Can you imagine a world where you are in control of what you share online? The answer to that lies in a decentralized internet where there are computers or servers talking to each other in the way they were meant to. There is a parallel universe called the Fediverse (read up about it, it's simple, trust me on this) that can solve some of the problems we have currently with an internet controlled by the corporations. The other problems can be solved with the use of open source software that provides alternatives for the services we use. Of course, the learning curve can be a little steep, and the experience not as smooth because they aren't tailored for us. But we'll sleep well knowing that you own your data. At a time when governments are trying to censor content which doesn't suit their propaganda, the existence of a decentralized internet also means that our space is universal and not controlled.

Importantly, we can urge those in our circles to give these alternatives a try to build a better, more democratic internet which respects voices instead of throttling those which one entity doesn't like. At time when machines are taking over all aspects of our life, let's bring back humanity to the internet.

I'll leave you with this talk by Aral Balkan.

And if you like something, please consider donating something to the creators (even the smallest contribution counts) to create an internet that's yours.

Dynamic websites on a fully peer-to-peer network is a combination most people would find hard to believe, yet that's exactly what ZeroNet has achieved. This piece of software allows anyone to create and view peer-to-peer websites that are impossible to take down, based entirely on static files. Unlike other peer-to-peer website networks, ZeroNet can power websites with user-generated content like forums and wikis. This article will teach you the basics of how it works.

What's a zite?

All ZeroNet sites — also called zites — start with an address. These are, like onion addresses, cryptographic keys. More specifically, they are bitcoin addresses. When creating a new zite, you are actually creating a key pair, where the private key allows the owner to sign new content and the public key allows anyone to verify the validity of the zite's files, even if they originate from an untrusted peer.

Once you have a key pair, you can start adding files to your zite. Zites act like any regular static website: you can add HTML, CSS and JavaScript as needed. In order for other peers to download the new files, you have to sign them with your private key. The hash of each file is stored in a special file called content.json, which conveniently contains a signature of itself. The new content.json file will propagate through the network and peers will automatically request files they need to keep their local copy up-to-date.

Now, what actually goes on when someone tries to access a zite? The first step is to get a list of peers that have the zite's content.json file. Once our client gets hold of the file, it can start to request all other files from the peers it has a connection with. This process typically takes about a second, which makes it faster than a lot of websites out there.

The process is actually a bit more involved than this, as ZeroNet supports optional files (only downloaded when needed), big files (files above 10MB are split up into pieces) and databases, which I will talk about next.

From static to dynamic

The content.json file contains file hashes, but not exclusively. It has a few more options that help in making a website dynamic. One of these options is named user_contents. It describes a set of rules surrounding user-generated content, like who can add files and how much custom data a user can have. When this option is used, users will be able to publish files themselves in a sub-directory named after their public key.

To illustrate how this can be used, let's take the example of the forum zite ZeroTalk. When a user creates a new post, ZeroNet will transparently create a new JSON file inside their custom files directory. This file will house the contents of the user's post as well as some metadata. To ensure the file's authenticity, each user has a content.json file that, like the one for the zite, contains file hashes. We now have a system where anyone can publish content to a zite, on a peer-to-peer network.

To make accessing these files more efficient, ZeroNet creates an SQL database for every zite that needs it. It is up to the zite owner to configure the mapping between custom user JSON files and the SQL database. We end up with a system where files go in, database comes out. The database itself is local: every client modifies it based on the files it has access to, and will do its best to keep it updated as new files come in.

This system has made fully decentralized websites possible: forums, wikis, mailboxes, torrent trackers, IRC-like message boards and more.

Domain names with NameCoin

ZeroNet relies on NameCoin .bit domains to make human-readable addresses. Anyone can create their own domains and subdomains as long as they have some NameCoin in a wallet and that the domain isn't already taken. The price of a single domain name is only a few cents, which makes custom addresses quite affordable.

Wrapping it up

I hope I've been able to shed some light on how ZeroNet works and what makes it great. There is a lot more to be said though, like how ZeroNet handles identities and peer discovery, how the protocol works or how it integrates with the Tor network.

I suggest anyone to try out the software for themselves, to create a small zite, then to publish it and watch it still be online years later. More information about the inner workings of ZeroNet can be found in the documentation.
