@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.

@movq@www.uninformativ.de Agreed that hashes have a benefit. I came up with a similar example where when I twted about an 11-character hash collision. Perhaps hashes could be made optional somehow. Like, you could use the “replyto” idea and then additionally put a hash somewhere if you want to lock in which version of the twt you are replying to.

@quark@ferengi.one I don’t really mind if the twt gets edited before I even fetch it. I think it’s the idea of my computer discarding old versions it’s fetched, especially if it’s shown them to me, that bugs me.

But I do like @movq@www.uninformativ.de’s suggestion on this thread that feeds could contain both the original and the edited twt. I guess it would be up to the author.

@sorenpeter@darch.dk I like this idea. Just for fun, I’m using a variant in this twt. (Also because I’m curious how it non-hash subjects appear in jenny and yarn.)

URLs can contain commas so I suggest a different character to separate the url from the date. Is this twt I’ve used space (also after “replyto”, for symmetry).

I think this solves:

• Changing feed identities: although @mckinley@twtxt.net points out URLs can change, I think this syntax should be okay as long as the feed at that URL can be fetched, and as long as the current canonical URL for the feed lists this one as an alternate.
  
• editing, if you don’t care about message integrity
  
• finding the root of a thread, if you’re not following the author
  

An optional hash could be added if message integrity is desired. (E.g. if you don’t trust the feed author not to make a misleading edit.) Other recent suggestions about how to deal with edits and hashes might be applicable then.

People publishing multiple twts per second should include sub-second precision in their timestamps. As you suggested, the timestamp could just be copied verbatim.

@prologic@twtxt.net I have some ideas:

• Add smartypants rendering, just like Yarn has.
  
• Add the ability to create individual twtxts, each named after their hash.
  
• Fix the formatting of the help. :-P

@prologic@twtxt.net

(#w4chkna) @falsifian@www.falsifian.org You mean the idea of being able to inline # url = changes in your feed?

Yes, that one. But @lyse@lyse.isobeef.org pointed out suffers a compatibility issue, since currently the first listed url is used for hashing, not the last. Unless your feed is in reverse chronological order. Heh, I guess another metadata field could indicate which version to use.

Or maybe url changes could somehow be combined with the archive feeds extension? Could the url metadata field be local to each archive file, so that to switch to a new url all you need to do is archive everything you’ve got and start a new file at the new url?

I don’t think it’s that likely my feed url will change.

@mckinley@twtxt.net Yes, changing domains is be a problem if you tie your identity to an https url. But I also worry about being stuck with a key I can’t rotate. Whatever gets used, it would be nice to be able to rotate identities. I like @lyse@lyse.isobeef.org’s idea for that.

@mckinley@twtxt.net Thanks for the feedback.

1. Yeah I agrees that nick sound not be part of syntax. Any valid URL to a twtxt.txt-file should be enough and is more clear, so it is not confused with a email (one of the the issues with webfinger and fedivese handles)
   
2. I think any valid URL would work, since we are not bound to look for exact matches. Accepting both http and https as well as a gemni and gophe could all work as long as the path to the twtxt.txt is the same.
   
3. My idea is that you quote the timestamp as it is in the original twtxt.txt that you are referring to, so you can do it by simply copy/pasting. Also what are the change that the same human will make two different posts within the same second?!
   

Regarding the whole cryptographic keys for identity, to me it seems like an unnecessary layer of complexity. If you move to a new house or city you tell people that you moved - you can do the same in a twtxt.txt. Just post something like “I move to this new URL, please follow me there!” I did that with my feeds at least twice, and you guys still seem to read my posts:)

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. ... 
# chain: ADDURL https://txt.sour.is/user/xuu

# chain: REVKEY kex14zwrx68cfkg28kjdstvcw4pslazwtgyeueqlg6z7y3f85h29crjsgfmu0w
# sig: ...

@movq@www.uninformativ.de Another idea: just hash the feed url and time, without the message content. And don’t twt more than once per second.

Maybe you could even just use the time, and rely on @-mentions to disambiguate. Not sure how that would work out.

Though I kind of like the idea of twts being immutable. At least, it’s clear which version of a twt you’re replying to (assuming nobody is engineering hash collisions).

In fact, maybe your public key idea is compatible with my last point. Just come up with a url scheme that means “this feed’s primary URL is actually a public key”, and then feed authors can optionally switch to that.

@movq@www.uninformativ.de good idea, considering it might occasionally not work at all (because of edited twtxts).

@prologic@twtxt.net How does yarn.social’s API fix the problem of centralization? I still need to know whose API to use.

Say I see a twt beginning (#hash) and I want to look up the start of the thread. Is the idea that if that twt is hosted by a a yarn.social pod, it is likely to know the thread start, so I should query that particular pod for the hash? But what if no yarn.social pods are involved?

The community seems small enough that a registry server should be able to keep up, and I can have a couple of others as backups. Or I could crawl the list of feeds followed by whoever emitted the twt that prompted my query.

I have successfully used registry servers a little bit, e.g. to find a feed that mentioned a tag I was interested in. Was even thinking of making my own, if I get bored of my too many other projects :-)

For following notifications I would say use webmetion refering to the the line in your twtxt.txt as per: https://darch.dk/mentions-twtxt
Or send them an email, so it would be an idea to add a # contact = mailto:me@domain.net to ones twtxt.txt

A stopgap setting that would let me stop all calls to /external matching a particular pattern (like this damn lovetocode999 nick) would do the job. Given the potential for abuse of that endpoint, having more moderation control over what it can do is probably a good idea.

@stigatle@yarn.stigatle.no @xuu@txt.sour.is @lyse@lyse.isobeef.org “Not cool”? I was receiving many broken (HTTP 400 error) requests per second from an IP address I didn’t recognize, right after having my VPS crash because the hard drive filled up with bogus data. None of this had happened on this VPS before, so it was a new problem that I didn’t understand and I took immediate action to get it under control. Of course I reported the IP address to its abuse email. That’s a 100% normal, natural, and “cool” thing to do in such a situation. At the time I had no idea it was @xuu@txt.sour.is .

The moment I realized it was @xuu@txt.sour.is and definitely a false alarm, I emailed the ISP and told them this was a false positive and to not ban or block the IP in question because it was not abusive traffic. They haven’t yet responded but I do hope they’ve stopped taking action, and if there’s anything else I can do to certify to them that this is not abuse then I will do that.

I run numerous services on that VPS that I rely on, and I spent most of my day today cleaning up the mess all this has caused. I get that this caused @xuu@txt.sour.is a lot of stress and I’m sincerely sorry about that and am doing what I can to rectify the situation. But calling me “not cool” isn’t necessary. This was an unfortunate situation that we’re trying to make right and there’s no need for criticizing anyone.

@prologic@twtxt.net This is weird, but today, out of nowhere, yarnd filled up the disk on the VPS where I run it. It’s never done anything like this before and I have no idea why it would start. But it threw almost 700 Gbytes of data into /tmp in files like this:

@movq@www.uninformativ.de Somewhere or another, I think in a William Byrd talk, I heard it suggested that the best ideas in computer science should fit on an index card (ah yes it’s this one: https://paperswelove.org/2017/video/will-byrd-most-beautiful-program/ ). He was referring to the basic principles of LISP/the lambda calculus, which have sometimes been called the Maxwell’s equations of computer programming (by Alan Kay). Simple, short, elegant, but very densely packed with meaning–generations of people have spent their whole careers unpacking what those simple rules can do.

Much of modern software feels like the polar opposite of that. Not only can you not write it on an index card, you never will be able to because people who write software don’t seem to aspire to try. I wish more people thought this way though!

@bmallred@staystrong.run overall this was pretty good and the run-walk intervals kept my heart rate low.

at around 0400 a car came racing (90-100 mph) down gulf blvd towards my direction. it turned its headlights off and actually lost traction at point and skidded a bit. okay, kids. then a bit later i hear the car coming back behind me… so i got as far to the right as i could in case the car skids again. as it passed me i looked over my shoulder and saw a police vehicle a bit back w/o lights on yet. then looking in front another cop and then they blocked the lanes to get the driver to stop. driver decided he wasn’t stopping and tried to swerve around the police and ended up ping-ponging between sides of the road. enough of that…

took a wrong turn after going over the first bridge, but luckily it went in a loop. didn’t really know exactly where i was going anyways and was just winging it from the get-go.

the rest of the run was pretty uneventful and just a fun experience. crazy idea accomplished.
