nips VS linux

I'm interested in this too. While I note the [slightly chaotic] plethora of NIPs[0], and many of them look blockchainy, NIP-01 is looks ultra pragmatic and simple, and is the only one that is required to be implemented, AFAIK.

For you and others following. Common in early nostr apps. The web-extension spec is defined in https://github.com/nostr-protocol/nips/blob/master/07.md. Most apps check for window.nostr, then fail silently when it's missing or blocked. There are also some popular extensions in that list.

https://github.com/nostr-protocol/nips/blob/master/65.md

The TLDR is that when a Nostr client supports NIP-65, it broadcasts to all known relays (which is continually updated/expanded) the list of relays that User A posts their stuff to.

This means that as long as User B is connected to at least one of those "all known relays", their client now knows what relays User A posts their stuff to, and will specifically fetch things from those relays when it needs to load User A's things.

It's essentially the Nostr take on the Gossip protocol: https://en.wikipedia.org/wiki/Gossip_protocol

I think your best bet here is Nostr (Notes and Other Stuff Transmitted by Relays): https://nostr.com https://github.com/nostr-protocol/nostr

Nostr isn't a federated platform like Mastodon or Lemmy, it's more similar to the AT protocol created by Bluesky, whilst being far simpler to understand and write apps using it. The nostr protocol is defined by a series of NIPs (Nostr implementation possibilites https://github.com/nostr-protocol/nips), the most basic of which can be implemented in a client or a relay in 50-100 lines of code in any modern programming language.

Each user runs a client, anyone can write a relay or run any of hundreds of existing implementations, both clients and relays can choose to support a number of NIPs. Users have a public-private keypair, and distribute notes to relays signed with their private key, which are verified by relays. Clients subscribe via websockets to any number of relays (I usually have 20-30), and receive notes from all users on those relays' databases, or filtered by the public keys of the users you're following. Relays for the most part don't communicate with each other. If you're ever blocked or banned from a relay, you'll still be able to have your notes seen as long as you have at least one relay in common with anyone who wants to see them. I run my own as well for extra resiliency.

At the moment there's ~50 standardised NIPs, which add features like likes, zaps (bitcoin tips for notes), user status, post expiration, mentions, search, DMs, and public chats. Nearly all of these are supported by popular clients and relays. While nostr is primarily used for social media at the moment, it's already possible to build upon as a protocol for pretty much any online service.

The total active user count on most public relays I'd estimate is somewhere around 500k to a million, though the nature of the protocol makes it impossible to estimate its true size. The perceived community on most relays before following anyone frankly can get pretty cancerous, mainly due to a lot of clients sorting notes by new by default, so I can only hope to high heaven it'll improve as it grows.

Though like any new non-centralised platform, it's more difficult to get started on for most non-technical users as they have to pick one of hundreds of clients to install, and requires caution to never leak your private key and be very wary of which clients you trust it with.

There is no "zaps balance". Zaps are just receipts of lightning payments.

The basic idea is that a lightning node will detect when the invoice with a nostr note inside is paid, and then send the receipt to nostr as a nostr note, with the original bolt11 invoice inside with the signature from the user who sent the zap.

It's all describe by NIP-57, a spec I put together to support this:

https://github.com/nostr-protocol/nips/blob/master/57.md

I was working on c-lightning at the time and I thought it would be really cool to replace the "like" button with an instant bitcoin micro-payment. I think it worked out quite well! There are many sites utilizing zaps in all aspects of the protocol, such as a decentralized market for AI job requests (data vending machines), zapgoals and zap fundraisers. All built on this note type. protocol synergy!

Take a look at NIP-23: Long-form Content https://github.com/nostr-protocol/nips/blob/master/23.md .

FFS predates FreeBSD and is in some capacity supported by all 3 major BSDs. I'm fairly confident that Linux actually supports it through the ufs driver ( https://github.com/torvalds/linux/tree/master/fs/ufs ); whether the use of different names in different places makes it better or worse is an exercise for the reader.

These are a bit easier to see what's going on:

Unfortunately Github doesn't have a way to render symbols for whitespace, but you can tell by selecting the spaces that the previous version had leading tabs. Linus changed it so that the tokens `default` and the number e.g. `12` are also separated by a tab. This is tricky, because the token "default" is seven characters, it will always give this added tab a width of 1 char which makes it always layout the same as if it were a space no matter if you use tab widths of 1, 2, 4, or 8.

There was also a Gentoo effort to run atop FreeBSD[0]. The challenge of course is that afaik none of the BSD kernel ABIs are considered stable. The stable interface is the BSD libc. That said, with binfmt_misc, I don't see a reason you couldn't just run (at least some) FreeBSD binaries on Linux with a thin syscall translation layer (rather something like qemu-system) and then your layer hooked via binfmt_misc. I'm not aware of anyone who has done this for FreeBSD, but prior efforts existed as alternate binfmts for SysVr4/5 ELF binaries[2]. Either way would take some elbow grease, but you *might* even be able just reuse binfmt_elf and just have a new interpreter for FreeBSD elf.

> The original less-than check was deemed incorrect

It was only deemed incorrect because of an information leak. Not because it's a valid use-case for user space to copy smaller portions of *hwrpb into user space. https://github.com/torvalds/linux/commit/21c5977a836e399fc71...

Correct. And the combined work needs to carry the MIT license text and copyright attributions for the MIT software authors. With binary distribution it must also be overt, not hidden in some source code drop, but directly accompanying the binary.

Many people who talk about relicensing never credit the MIT developers or distribute the MIT license text. "Because it's GPL now."

I don't think that you believe that, but many developers do.

Some don't see the need for source code scans for Open Source compliance, because the license.txt says GPL, so it's GPL. Prime example is the Linux kernel. There is code under different licenses in there, but people don't even read https://github.com/torvalds/linux/blob/master/COPYING till the end ("In addition, other licenses may also apply.") and conclude it's simply GPL 2 and nothing else.

Also be aware that sublicensing is not the same as relicensing.

He notoriously hates GNU Emacs, yes.

So If we would only count code and not comments, it is only 9489 LoC Rust. Which would be about 0.03% and if we take all lines and not only LoC it would be around 0.05%

AIUI fsync is built on futex_waitv which has been upstreamed. So this has to be more than that.
