Today I discovered a new PDF reader, that I think folks doing research will like a lot.

It's called Sioyek [^1] and it's something of a software for power users. It minimal, with VIM style key bindings and hidden keyboard shortcuts. The website shows a great deal of the cool features, I will just mention a very nice addition I'm enjoying.

You can right click a reference in the document, and a small rectangle overlay will show you the linked content without moving your current view, so you do not lose track of where you started.

It's very useful to peek at an equation or a citation and keep reading afterwards.

GCN: Ireland’s first Gaeltacht for LGBTQ+ adults launches this summer

Taking place this August, the week-long summer camp has been designed for all levels of LGBTQ+ learners of Irish.

@modulux Kademlia/IPFS solve one specific problem (namely that of being able to download some data whose hash you already know), blockchains allow you to run any algorithm computable by a Turing machine.

THe problem with Kademlia and IPFS is that you need to know the hash of the data you want to download beforehand, and there's no way for the data's original author to distribute updates. There's also the problem of discoverability, there are no human-friendly names, so you need a centralized index of names to hashes.

@kuba No.

A blockchain can provide a unique mapping of names to values. It's centralized in the sense that there's only one mapping and every network participant agrees on what a given name is mapped to, but decentralized in the sense that only authorized users (where the smart contract defines what is meant by "authorized") are allowed to change mappings.

THe reason such a system cannot possibly work without a cryptocurrency is that you need some incentive against scalpers taking all the names for themselves on day one. If names are completely free to acqquire, somebody is inevitably going to get all the interesting ones and then they won't be free to acquire any more.

What happens when someone forks a blockchain and people disagree which one is the true one?

Also, how do you read the data from the blockchain? Do you download the entire blockchain to your HDD? Or do you rely on some intermediary who wraps the blockchain in a lightweight API? Who is the intermediary then? How do we trust them?

Also, what's supposed to happen when someone steals your domain through some hacky means? Then there'll be no way to get it back, it will be gone forever.

@kuba Blockchains have built-in mechanisms to decide on how to deal with forks. This is why proof-of-work was originally invented, with PoW, clients always choose the fork with more work applied to it. Proof of stake and other consensus mechanisms provide similar guarantees, but require far less energy.

You can make a hardfork (essentially changing the rules of your blockchain), but then it's up to which client you use, if you use a client that respects and implements the hardfork, you're on the forked version, otherwise your client treats the hardfork as illegitimate and only uses the unforked version.

@kuba re: reading the data, there are some designs for DNS-like chains that allow you to be a lightweight client with no need to trust an intermediary. Essentially, you only need to download the headers of each block (which are much smaller than the blocks themselves), you download the rest on-demand. Having the headers (which contain the block hashes) ensures that nobody can tamper with the block contents without your knowledge.

@kuba Re: hacking, this is a fundamental dilemma, if your registrar has the ability to forcibly transfer your domain to somebody else, they can help recover it in case of a hack, but they can also disable it when their automated AI systems mistakenly flag it as suspicious.

There are ways to mitigate this problem. Handshake for example has a concept of "domain burning", if somebody steals a copy of your key and tries to transfer your domain to their own, you have some time (two weeks I think) to disable the domain completely, making it unavaiblable to both you and the hacker. This removes any financial incentives for domain hacking, as most people would rather lose their domain than have it go to a hacker.

There are also other designs where you have multiple parties that need to authorize a transfer. You could even design this in a way where you need a both your key and a registrar's key to transfer a domain to somebody else, but the registrar's key isn't allowed to make any changes to the domain without your express consent.

That sounds like centralization with extra steps

I have a collection of boot-up sounds from various items, but always looking for more. If you're able to record directly from a device not listed here, and provide a lossless file to me to add to the collection, I'd be grateful for your digital donations.
.wav or .flac is preferred and don't worry if you can't edit yourself, only capture, I can do that. Thank you.
