** Sleepy garden beds **
This afternoon I put the garden to sleep for the fall; in the past we’ve had some fall and winter vegetables going, but this year that didn’t happen, so, I emptied out the rain barrels, cleaned them out, trundled them to a place where they wouldn’t get blown around by any winds, mulched some of the beds, weeded and generally plotzed around like a garden goblin.

I share I did write up an algorithm for it at some point I think it is lost in a git comment someplace. I’ll put together a pseudo/go code this week.

Super simple:

Making a reply:

1. If yarn has one use that. (Maybe do collision check?)
   
2. Make hash of twt raw no truncation.
   
3. Check local cache for shortest without collision
   
   • in SQL: select len(subject) where head_full_hash like subject || '%'
     

Threading:

1. Get full hash of head twt
   
2. Search for twts
   
   • in SQL: head_full_hash like subject || '%' and created_on > head_timestamp
     

The assumption being replies will be for the most recent head. If replying to an older one it will use a longer hash.

@prologic@twtxt.net I wanted to wait for things to settle down. It’s still unclear to me in which direction we’re going – and if that new/different stuff is even possible to implement in jenny. That said, I’ve been really busy with private stuff these last few days, I’ve lost track of most of what you’re discussing. 🥴

If we stuck with Blake2b for Twt Hash(es); what do we think we need to reasonably go to in bit length/size?

=> https://gist.mills.io/prologic/194993e7db04498fa0e8d00a528f7be6

e.g: (turns out @xuu@txt.sour.is is right about Blak2b being easy/simple too!):

$ printf "%s\t%s\t%s" "https://example.com/twtxt.txt" "2024-09-29T13:30:00Z" "Hello World!" | b2sum -l 32 -t | awk '{ print $1 }'
7b8b79dd

@prologic@twtxt.net Regarding the new way of generating twt-hashes, to me it makes more sense to use tabs as separator instead of spaces, since the you can just copy/past a line directly from a twtxt-file that already go a tab between timestamp and message. But tabs might be hard to “type” when you are in a terminal, since it will activate autocomplete…🤔

Another thing, it seems that you sugget we only use the domain in the hash-creation and not the full path to the twtxt.txt

Starting a couple of new projects (geez where do I find the time?!):

HomeTunnel:

HomeTunnel is a self-hosted solution that combines secure tunneling, proxying, and automation to create your own private cloud. Utilizing Wireguard for VPN, Caddy for reverse proxying, and Traefik for service routing, HomeTunnel allows you to securely expose your home network services (such as Gitea, Poste.io, etc.) to the Internet. With seamless automation and on-demand TLS, HomeTunnel gives you the power to manage your own cloud-like environment with the control and privacy of self-hosting.

CraneOps:

craneops is an open-source operator framework, written in Go, that allows self-hosters to automate the deployment and management of infrastructure and applications. Inspired by Kubernetes operators, CraneOps uses declarative YAML Custom Resource Definitions (CRDs) to manage Docker Swarm deployments on Proxmox VE clusters.

And finally the legibility of feeds when viewing them in their raw form are worsened as you go from a Twt Subject of (#abcdefg12345) to something like (https://twtxt.net/user/prologic/twtxt.txt 2024-09-22T07:51:16Z).

There is also a ~5x increase cost in memory utilization for any implementations or implementors that use or wish to use in-memory storage (yarnd does for example) and equally a 5x increase in on-disk storage as well. This is based on the Twt Hash going from a 13 bytes (content-addressing) to 63 bytes (on average for location-based addressing). There is roughly a ~20-150% increase in the size of individual feeds as well that needs to be taken into consideration (on the average case).

So really your argument is just that switching to a location-based addressing “just makes sense”. Why? Without concrete pros/cons of each approach this isn’t really a strong argument I’m afraid. In fact I probably need to just sit down and detail the properties of both approaches and the pros/cons of both.

I also don’t really buy the argument of simplicity either personally, because I don’t technically see it much more difficult to take a echo -e "<url>\t<timestamp>\t<content>" | sha256sum | base64 as the Twt Subject or concatenating the <url> <timestamp> – The “effort” is the same. If we’re going to argue that SHA256 or cryptographic hashes are “too complicated” then I’m not really sure how to support that argument.

I wrote some code to try out non-hash reply subjects formatted as (replyto ), while keeping the ability to use the existing hash style.

I don’t think we need to decide all at once. If clients add support for a new method then people can use it if they like. The downside of course is that this costs developer time, so I decided to invest a few hours of my own time into a proof of concept.

With apologies to @movq@www.uninformativ.de for corrupting jenny’s beautiful code. I don’t write this expecting you to incorporate the patch, because it does complicate things and might not be a direction you want to go in. But if you like any part of this approach feel free to use bits of it; I release the patch under jenny’s current LICENCE.

Supporting both kinds of reply in jenny was complicated because each email can only have one Message-Id, and because it’s possible the target twt will not be seen until after the twt referencing it. The following patch uses an sqlite database to keep track of known (url, timestamp) pairs, as well as a separate table of (url, timestamp) pairs that haven’t been seen yet but are wanted. When one of those “wanted” twts is finally seen, the mail file gets rewritten to include the appropriate In-Reply-To header.

Patch based on jenny commit 73a5ea81.

https://www.falsifian.org/a/oDtr/patch0.txt

Not implemented:

• Composing twts using the (replyto …) format.
  
• Probably other important things I’m forgetting.

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 think keeping hashes is a must. If anything for that “feels good” feeling.

Hey, @movq@www.uninformativ.de, a tiny thing to add to jenny, a -v switch. That way when you twtxt “That’s an older format that was used before jenny version v23.04”, I can go and run jenny -v, and “duh!” myself on the way to a git pull. :-D

Regarding jenny development: There have been enough changes in the last few weeks, imo. I want to let things settle for a while (potential bugfixes aside) and then I’m going to cut a new release.

yarnd just doesn’t render the subject. Fair enough. It’s (replyto http://darch.dk/twtxt.txt 2024-09-15T12:50:17Z), and if you don’t want to go on a hunt, the twt hash is weadxga: https://twtxt.net/twt/weadxga

@aelaraji@aelaraji.com this is my change on main.go (but it can be done on a template now, so no reason to touch the code):

                                 <time class="dt-published" datetime="{{ $twt.Created | date "2006-01-02T15:04:05Z07:00" }}">
                                        {{ $twt.Created | date "2006-01-02 15:04:05 MST" }}
                                  </time>

See https://ferengi.one. I am going to further customise things, but that’s a start.

@lyse@lyse.isobeef.org Sorry, I don’t think I ever had charset=utf8. I just noticed that a few days ago. OpenBSD’s httpd might not support including a parameter with the mime type, unfortunately. I’m going to look into it.

Now WTF!? Suddenly, @falsifian@www.falsifian.org’s feed renders broken in my tt Python implementation. Exactly what I had with my Go rewrite. I haven’t touched the Python stuff in ages, though. Also, tt and tt2 do not share any data at all.

By any chance, did you remove the ; charset=utf-8 from your Content-Type: text/plain header, falsifian?

Image

@movq@www.uninformativ.de Non-ASCII characters were broken. Like U+2028, degrees (°), etc.

Turns out I used a silly library to detect the encoding and transform to UTF-8 if needed. When there is no Content-Type header, like for local files, it looks at the first 1024 bytes. Since it only saw ASCII in that region, the damn thing assumed the data to be in Windows-1252 (which for web pages kinda makes sense):

// TODO: change default depending on user's locale?
return charmap.Windows1252, "windows-1252", false

https://cs.opensource.google/go/x/net/+/master:html/charset/charset.go;l=102

This default is hardcoded and cannot be changed.

Trying to be smart and adding automatic support for other encodings turned out to be a bad move on my end. At least I can reduce my dependency list again. :-)

I now just reject everything that explicitly specifies something different than text/plain and an optional charset other than utf-8 (ignoring casing). Otherwise I assume it’s in UTF-8 (just like the twtxt file format specification mandates) and hope for the best.

Hmmmm, I somehow run into an encoding problem where my inserted data end up mangled in the database. But, both SQLite and Go use UTF-8. What’s happening here? :-?

@movq@www.uninformativ.de I did the same. jenny fetches archives, yes, but that twtxt I am referring about is no longer. If you fetch it, but I don’t, there is certainly something going on…

@movq@www.uninformativ.de I figured it will be something like this, yet, you were able to reply just fine, and I wasn’t. Looking at your twtxt.txt I see this line:

2024-09-16T17:37:14+00:00	(#o6dsrga) @<prologic https://twtxt.net/user/prologic/twtxt.txt>

@<quark https://ferengi.one/twtxt.txt> This is what I get. 🤔

Which is using the right hash. Mine, on the other hand, when I replied to the original, old style message (Message-Id: <o6dsrga>), looks like this:

2024-09-16T16:42:27+00:00	(#o) @<prologic https://twtxt.net/user/prologic/twtxt.txt> this was your first twtxt. Cool! :-P

What did you do to make yours work? I simply went to the oldest @prologic@twtxt.net’s entry on my Maildir, and replied to it (jenny set the reply-to hash to #o, even though the Message-Id is o6dsrga). Since jenny can’t fetch archived twtxts, how could I go to re-fetch everything? And, most importantly, would re-fetching fix the Message-Id:?

@prologic@twtxt.net I am going to light some candles this weekend to “La Virgen de Macarena” to make it happen! :-D

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. ...

@mckinley@twtxt.net To answer some of your questions:

Are SSH signatures standardized and are there robust software libraries that can handle them? We’ll need a library in at least Python and Go to provide verified feed support with the currently used clients.

We already have this. Ed25519 libraries exist for all major languages. Aside from using ssh-keygen -Y sign and ssh-keygen -Y verify, you can also use the salty CLI itself (https://git.mills.io/prologic/salty), and I’m sure there are other command-line tools that could be used too.

If we all implemented this, every twt hash would suddenly change and every conversation thread we’ve ever had would at least lose its opening post.

Yes. This would happen, so we’d have to make a decision around this, either a) a cut-off point or b) some way to progressively transition.

Where the Eder flows into the Fulda
Just in time before it gets cold and rainy again next week, I took advantage of today to go for a short bike ride. Upstream along the Fulda, over to the Eder and then to where the Eder flows into the Fulda. This was the short (49 km) of the two versions I had planned for this. The longer version is almost 90 kilometers long. Let’s see if I can still do it this year… ⌘ Read more

@prologic@twtxt.net Some criticisms and a possible alternative direction:

1. Key rotation. I’m not a security person, but my understanding is that it’s good to be able to give keys an expiry date and replace them with new ones periodically.

2. It makes maintaining a feed more complicated. Now instead of just needing to put a file on a web server (and scan the logs for user agents) I also need to do this. What brought me to twtxt was its radical simplicity.

Instead, maybe we should think about a way to allow old urls to be rotated out? Like, my metadata could somehow say that X used to be my primary URL, but going forward from date D onward my primary url is Y. (Or, if you really want to use public key cryptography, maybe something similar could be used for key rotation there.)

It’s nice that your scheme would add a way to verify the twts you download, but https is supposed to do that anyway. If you don’t trust https to do that (maybe you don’t like relying on root CAs?) then maybe your preferred solution should be reflected by your primary feed url. E.g. if you prefer the security offered by IPFS, then maybe an IPNS url would do the trick. The fact that feed locations are URLs gives some flexibility. (But then rotation is still an issue, if I understand ipns right.)

@lyse@lyse.isobeef.org 31°C here, feels like 33°C, with a lovely 75% of humidity. It has been raining, on and off (to make matter “better”) the whole day until now. No horses here, but if you go outside you will smell the same smell of farm animals (like goats, or pigs). That’s because two or three kilometres from here there are private farms, and when the wind blows in such way, well, we are reminded of their existence.

I haven’t left the house, so it feels well under air conditioning. In two more hours I will call it quits from the work day, and will have to dash to the grocery to get supplies for tonight’s meal (arroz con gandules). I will let you know how it truly feels out there then. :-D

For those swollen fingers, nothing better than a mildly cold shower! Oh, and paws off the keyboard! :-P

When we passed a few horses in the forest, there was really strong soup odor in the air. It didn’t smell like horse at all, but soup. Maybe they’ve been soup horses, chickens were out of stock.

29°C, zero wind, extremely humid, luckily the sun was behind the clouds. I’m soaking wet, sweat ran down in streams and dripped in my eyes, it burned a bit. The sky is getting a little dark, I hope the thunderstorm and rain are really arriving here later. Rain had always been finally cancelled the couple last days.

I’m gotta go cool off my fingers now, they’re swollen from the heat.

@bender@twtxt.net On twtxt, I follow all feeds that I can find (there are some exceptions, of course). There’s so little going on in general, it hardly matters. 😅

And I just realized: Mutt’s layout helps a lot. Skimming over new twts is really easy and it’s not a big loss if there are a couple of shitposts™ in my “timeline”. This is very different from Mastodon (both the default web UI and all clients I’ve tried), where the timeline is always huge. Posts take up a lot of space on screen. Makes me think twice if I want to follow someone or not. 😅

(I mostly only follow Hashtags on Mastodon anyway. It’s more interesting that way.)
