In-reply-to » (#ucgvfmq) @movq going a little sideways on this, "*If twtxt/Yarn was to grow bigger, then this would become a concern again. But even Mastodon allows editing, so how much of a problem can it really be? 😅*", wouldn't it preparing for a potential (even if very, very, veeeeery remote) growth be a good thing? Mastodon signs all messages, keeps a history of edits, and it doesn't break threads. It isn't a problem there.😉 It is here.

i feel like we should isolate a subset of markdown that makes sense and built it into lextwt. it already has support for links and images. maybe basic formatting bold, italic. possibly block quote and bullet lists. no tables or footnotes

the stem matching is the same as how GIT does its branch hashes. i think you can stem it down to 2 or 3 sha bytes.

if a client sees someone in a yarn using a byte longer hash it can lengthen to match since it can assume that maybe the other client has a collision that it doesnt know about.

@prologic@twtxt.net the basic idea was to stem the hash.. so you have a hash abcdef0123456789... any sub string of that hash after the first 6 will match. so abcdef, abcdef012, abcdef0123456 all match the same. on the case of a collision i think we decided on matching the newest since we archive off older threads anyway. the third rule was about growing the minimum hash size after some threshold of collisions were detected.

There is nothing wrong with how we currently run a diff to see what has been removed. if i build a merkle tree off all the twt hashes in a feed i can use that to verify a twt should be in a feed or not. and gossip that to my peers.

isn’t the benefit of blake2b that it is a more efficient algo than sha1 and has the same or similar entropy to sha3? i thought we had partially solved this with some type of expanding hash size? additionally we could increase bit density by using base36 or base64/url-safe…

@prologic@twtxt.net a signature IS encryption in reverse. If my private key becomes compromised then they can impersonate me. Being able to manage promotion and revocation of keys needed even in a system where its used for just signatures.

⤋ Read More

the right way to solve this is to use public/private key(s) where you actually have a public key fingerprint as your feed’s unique identity that never changes.

i would rather it be a random value signed by a key. That way the key can change but the value stays the same.

Interesting.. QUIC isn’t very quick over fast internet.

QUIC is expected to be a game-changer in improving web application performance. In this paper, we conduct a systematic examination of QUIC’s performance over high-speed networks. We find that over fast Internet, the UDP+QUIC+HTTP/3 stack suffers a data rate reduction of up to 45.2% compared to the TCP+TLS+HTTP/2 counterpart. Moreover, the performance gap between QUIC and HTTP/2 grows as the underlying bandwidth increases. We observe this issue on lightweight data transfer clients and major web browsers (Chrome, Edge, Firefox, Opera), on different hosts (desktop, mobile), and over diverse networks (wired broadband, cellular). It affects not only file transfers, but also various applications such as video streaming (up to 9.8% video bitrate reduction) and web browsing. Through rigorous packet trace analysis and kernel- and user-space profiling, we identify the root cause to be high receiver-side processing overhead, in particular, excessive data packets and QUIC’s user-space ACKs. We make concrete recommendations for mitigating the observed performance issues.

So this is a great thread. I have been thinking about this too.. and what if we are coming at it from the wrong direction? Identity being tied to a given URL has always been a pain point. If i get a new URL its almost as if i have a new identity because not only am I serving at a new location but all my previous communications are broken because the hashes are all wrong.

What if instead we used this idea of signatures to thread the URLs together into one identity? We keep the URL to Hash in place. Changing that now is basically a no go. But we can create a signature chain that can link identities together. So if i move to a new URL i update the chain hosted by my primary identity to include the new URL. If i have an archived feed that the old URL is now dead, we can point to where it is now hosted and use the current convention of hashing based on the first url:

The signature chain can also be used to rotate to new keys over time. Just sign in a new key or revoke an old one. The prior signatures remain valid within the scope of time the signatures were made and the keys were active.

The signature file can be hosted anywhere as long as it can be fetched by a reasonable protocol. So say we could use a webfinger that directs to the signature file? you have an identity like frank@beans.co that will discover a feed at some URL and a signature chain at another URL. Maybe even include the most recent signing key?

From there the client can auto discover old feeds to link them together into one complete timeline. And the signatures can validate that its all correct.

I like the idea of maybe putting the chain in the feed preamble and keeping the single self contained file.. but wonder if that would cause lots of clutter? The signature chain would be something like a log with what is changing (new key, revoke, add url) and a signature of the change + the previous signature.

# chain: ADDKEY kex14zwrx68cfkg28kjdstvcw4pslazwtgyeueqlg6z7y3f85h29crjsgfmu0w 
# sig: BEGIN SALTPACK SIGNED MESSAGE. ...

HTTP/2 differs from 1.x by becoming a binary protocol, it also multiplexes multiple channels over the same connection and has the ability to prefetch related content to the browser to lower the perceived latency.

HTTP/3 moves the binary protocol from HTTP/2 over to QUIC which is based on UDP instead of TCP. This makes it better suited to mobile or unstable networks where handling of transmission errors can be handled at a higher level.

Its like old school TV but with youtube videos. Each channel has a subject and the channels play in a sort of realtime. so no going forward or back. Perfect for channel surfing.

We received the abuse report below regarding network abuse from the IP address indicated.
On researching I see that HTTPS (tcp 443) traffic is continuing and originating from you NAT IP address 100.64.x.x
This was further found to be originating from your firewall/router at 192.168.x.x (MAC D8:58:D7:x:x:x).
This abuse is continuing and constitues a violation of [ISP] Acceptable Use Policy and Terms of Service.
Please take action to identify the source of the abuse and prevent it from continuing.
Failure to stop the abuse may result in suspension or cancellation of service.

Thank you,

I feel like complexity is measured differently at different levels of a project..

  • at the function level you use cyclomatic complexity or how many branches internally and how much you need to keep in mind as it calls out to other functions.
  • at a file/module level is a balance of the module doing too much against being so granular that you have cross dependency across modules. I have trouble with keeping things dry at this level because it can lead to parts being so abstract or generalized that it adds complexity.
  • at a project level i suppose its a matter of how coupled things are across sub-modules.

it works fine if you properly escape your urls!

 URIs include components and subcomponents that are delimited by
   characters in the "reserved" set.  These characters are called
   "reserved" because they may (or may not) be defined as delimiters by
   the generic syntax, by each scheme-specific syntax, or by the
   implementation-specific syntax of a URI's dereferencing algorithm.
   If data for a URI component would conflict with a reserved
   character's purpose as a delimiter, then the conflicting data must be
   percent-encoded before the URI is formed.

      reserved    = gen-delims / sub-delims
      gen-delims  = ":" / "/" / "?" / "#" / "[" / "]" / "@"
      sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
                  / "*" / "+" / "," / ";" / "="

@mckinley@twtxt.net for me:

  • a wall mount 6U rack which has:
    • 1U patch panel
    • 1U switch
    • 2U UPS
    • 1U server, intel atom 4G ram, debian (used to be main. now just has prometheus)
  • a mini ryzon 16 core 64G ram, fedora (new main)
    • multiple docker services hosted.
  • synology nas with 4 2TB drives
  • turris omnia WRT router -> fiber uplink

network is a mix of wireguard, zerotier.

  • wireguard to my external vms hosted in various global regions.
    • this allows me ingress since my ISP has me behind CG-NAT
  • zerotier is more for devices for transparent vpn into my network

i use ssh and remote desktop to get in and about. typically via zerotier vpn. I have one of my VMs with ssh on a backup port for break glass to get back into the network if needed.

everything has ipv6 though my ISP does not provide it. I have to tunnel it in from my VMs.
