Do you k ow what you clicked on before going back?

@eldersnake@we.loveprivacy.club Sweet thank you! 🙇‍♂️ I’ll merge this PR tonight I think.

Seems to be working OK 🤔

Pelos vistos antigamente havia uma coisa chamada “baile tipo Cascais”. Mas como o mundo subversivo dos anos 50 e 60 em Portugal não está bem documentado, há zero resultados a uma pesquisa do termo nos motores de busca da Internet… resta-me a imaginação para tirar as conclusões (provavelmente erradas) de como seria tal baile.

@david@collantes.us Well, I wouldn’t recommend using my code for your main jenny use anyway. If you want to try it out, set XDG_CONFIG_HOME and XDG_CACHE_HOME to some sandbox directories and only run my code there. If @movq@www.uninformativ.de is interested in any of this getting upstreamed, I’d be happy to try rebasing the changes, but otherwise it’s a proof of concept and fun exercise.

@falsifian@www.falsifian.org hiya from the Sunshine State (also known as a never-ending hell, LOL)!

I forgot to git add a new test file. Added to the patch now at https://www.falsifian.org/a/oDtr/patch0.txt

@falsifian@www.falsifian.org this one hits hard, as jenny was just updated today. :‘-(

its replacing the contents of body for some reason.

@david@collantes.us Hello!

@prologic@twtxt.net Hi. i have noticed sometimes when i hit the back button i lose all the surrounding layout and just have a list of twts.

BTW this code doesn’t incorporate existing twts into jenny’s database. It’s best used starting from scratch. I’ve been testing it using a custom XDG_CACHE_HOME and XDG_CONFIG_HOME to avoid messing with my “real” jenny data.

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.

Hmm…

@lyse@lyse.isobeef.org indeed! There is no “central authority” acting as witness, and notary. The more I think of it… LOL.

@movq@www.uninformativ.de I recognise him, but yes, he has aged quite a bit. I mean, I look at myself in the mirror and can’t, often, recognise myself. Ageing is a bitch! 😅

I mean, really, it couldn’t get any better. I love it!

@movq@www.uninformativ.de perfect in every way. Configurable too! Thank you!

@movq@www.uninformativ.de yes, that’s perfect! <3

@eldersnake@we.loveprivacy.club I wanted to ask you, are you running Headscale and WireGuard on the same VPS? I want to test Headscale, but currently run a small container with WireGuard, and I wonder if I need to stop (and eventually get rid of) the container to get Headscale going. Did you use the provided .deb to install Headscale, or some other method?

@david@collantes.us I think we can!

@prologic@twtxt.net I read it. I understand it. Hopefully a solution can be agreed upon that solves the editing issue, whilst maintaining the cryptographic hash.

e.g: Shutdown yarnd and cp -a yarn.db yarn.db.bak before testing this PR/branch.

Can I get someone like maybe @xuu@txt.sour.is or @abucci@anthony.buc.ci or even @eldersnake@we.loveprivacy.club – If you have some spare time – to test this yarnd PR that upgrades the Bitcask dependency for its internal database to v2? 🙏

VERY IMPORTANT If you do; Please Please Please backup your yarn.db database first! 😅 Heaven knows I don’t want to be responsible for fucking up a production database here or there 🤣

nevermind; I think this might be some changes internally in Go 1.23 and a dependency I needed to update 🤞

Can someone much smarter than me help me figure out a couple of newly discovered deadlocks in yarnd that I think have always been there, but only recently uncovered by the Go 1.23 compiler.

Location Addressing is fine in smaller or single systems. But when you’re talking about large decentralised systems with no single point of control (kind of the point) things like independable variable integrity become quite important.

What is being proposed as a counter to content-addressing is called location-addressing. Two very different approaches, both with pros/cons of course. But a local cannot be verified, the content cannot be be guaranteed to be authenticate in any way, you just have to implicitly trust that the location points to the right thing.

For example, without content-addressing, you’d never have been able to find let alone pull up that ~3yr old Twt of me (my very first), hell I’d even though I lost my first feed file or it became corrupted or something 🤣 – If that were the case, it would actually be possible to reconstruct the feed and verify every single Twt against the caches of all of you 🤣

@david@collantes.us I really thinks articles like this explain the benefits far better than I can.

@prologic@twtxt.net I know the role of the current hash is to allow referencing (replies and, thus, threads), and it also represents a “unique” way to verify a twtxt hasn’t been tampered with. Is that second so important, if we are trying to allow edits? I know if feels good to be able to verify, but in reality, how often one does it?

@movq@www.uninformativ.de could it be possible to have compressed_subject(msg_singlelined) be configurable, so only a certain number of characters get displayed, ending on ellipses? Right now the entire twtxt is crammed into the Subject:. This request aims to make twtxts display on mutt/neomutt, etc. more like emails do.

@david@collantes.us Oh ! 🤦‍♂️

@david@collantes.us Witout including the content, it’s no longer really “content addressing” now is it? You’re essentially only addressing say nick+timestamp or url+timestamp.

@prologic@twtxt.net I don’t trust Google with anything, sorry, pass. Oh, and you need to sign in on your Google Account (or whatever they call it these days).

@prologic@twtxt.net how about hashing a combination of nick/timestamp, or url/timestamp only, and not the twtxt content? On edit those will not change, so no breaking of threads. I know, I know, just adding noise here. :-P

Speaking of AI tech (sorry!); Just came across this really cool tool built by some engineers at Google™ (currently completely free to use without any signup) called NotebookLM 👌 Looks really good for summarizing and talking to document 📃

@eldersnake@we.loveprivacy.club there has to be less reliance on a single point of failure. It is not so much about creating jobs in the US (which come with it, anyway), but about the ability to produce what’s needed at home too. What’s the trade off? Is it going to be a little bit more expensive to manufacture, perhaps?

@eldersnake@we.loveprivacy.club Yeah I’m looking forward to that myself 🤣 It’ll be great to see where technology grow to a level of maturity and efficiency where you can run the tools on your own PC or Device and use it for what, so far, I’ve found it to be somewhat decent at; Auto-Complete, Search and Q&A.

@prologic@twtxt.net That’s definitely a little less depressing, when thinking of it that way 🤣 Be interesting when the hype dies down.

I’m not the biggest Apple fan around, but that is pretty awesome.

i found this site by searching “thing-fish”

@sorenpeter@darch.dk I really don’t think we can ignore the last ~3 years and a bit of this threading model working quite well for us as a community across a very diverse set of clients and platforms. We cannot just drop something that “mostly works just fine” for the sake of “simplicity”. We have to weight up all the options. There are very real benefits to using content addressing here that really IMO shouldn’t be disregarded so lightly that actually provide a lot of implicit value that users of various clients just don’t get to see. I’d recommend reading up on the ideas behind content addressing before simply dismissing the Twt Hash spec entirely, it wasn’t even written or formalised by me, but I understand how it works quite well 😅 The guy that wrote the spec was (is?) way smarter than I was back then, probably still is now 🤣

Estava tentado em escolher outra coisa para esta #musiquinta , mas seria enganar-me. Não consigo pensar em #covers sem me vir esta logo imediatamente à cabeça, é como se estivesse enfeitiçado…

@quark@ferengi.one It does not. That is why I’m advocating for not using hashes for treads, but a simpler link-back scheme.

@falsifian@www.falsifian.org Right I see. Yeah maybe we want to avoid that 🤣 I do kind of tend to agree with @xuu@txt.sour.is in another thread that there isn’t actually anything wrong with our use of Blake2 at all really, but we may want to consider all our options.

@xuu@txt.sour.is I don’t think this is a lextwt problem tbh. Just the Markdown aprser that yarnd currently uses. twtxt2html uses Goldmark and appears to behave better 🤣

@xuu@txt.sour.is Long while back, I experimented with using similarity algorithms to detect if two Twts were similar enough to be considered an “Edit”.

Right I see what you mean @xuu@txt.sour.is – Can you maybe come up with a fully fleshed out proposal for this? 🤔 This will help solve the problem of hash collision that result from the Twt/hash space growing larger over time without us having to change anything about the way we construct hashes in the first place. We just assume spec compliant clients will just dynamically handle this as the space grows.

@xuu@txt.sour.is I think we never progressed this idea further because we weren’t sure how to tell if a hash collision would occur in the first place right? In other words, how does Client A know to expand a hash vs. Client B in a 100% decentralised way? 🤔

Plus these so-called “LLM”(s) have a pretty good grasp of the “shape” of language, so they appear to be quite intelligent or produce intelligible response (when they’re actually quite stupid really).

@eldersnake@we.loveprivacy.club You don’t get left behind at all 🤣 It’s hyped up so much, it’s not even funny anymore. Basically at this point (so far at least) I’ve concluded that all this GenAI / LLM stuff is just a fancy auto-complete and indexing + search reinvented 🤣

Getting a little sick of AI this, AI that. Yes I’ll be left behind while everyone else jumps on the latest thing, but I’m not sure I care.

Oh. looks like its 4 chars. git show 64bf

@prologic@twtxt.net where was that idea?

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.

@prologic@twtxt.net Wikipedia claims sha1 is vulnerable to a “chosen-prefix attack”, which I gather means I can write any two twts I like, and then cause them to have the exact same sha1 hash by appending something. I guess a twt ending in random junk might look suspcious, but perhaps the junk could be worked into an image URL like

Image

git only uses sha1 because they’re stuck with it: migrating is very hard. There was an effort to move git to sha256 but I don’t know its status. I think there is progress being made with Game Of Trees, a git clone that uses the same on-disk format.

I can’t imagine any benefit to using sha1, except that maybe some very old software might support sha1 but not sha256.

@bender@twtxt.net This is the different Markdown parsers being used. Goldmark vs. gomarkdown. We need to switch to Goldmark 😅

Apple A16 SoC Now Manufactured In Arizona
“Apple has begun manufacturing its A16 SoC at the newly-opened TSCM Fab 21 in Arizona,” writes Slashdot reader NoMoreACs. AppleInsider reports: According to sources of Tim Culpan, Phase 1 of TSMC’s Fab 21 in Arizona is making the A16 SoC of the iPhone 14 Pro in “small, but significant, numbers. The production is largely a test for the facility at this stage, but more production is expected … ⌘ Read more

@quark@ferengi.one i’m guessing the quotas text should’ve been emphasized?

@slashdot@feeds.twtxt.net NahahahahHa 🤣 So glad I don’t use LinkedIn 🤦‍♂️

@falsifian@www.falsifian.org No u don’t sorry. But I tend to agree with you and I think if we continue to use hashes we should keep the remainder in mind as we choose truncation values of N

@falsifian@www.falsifian.org Mostly because Git uses it 🤣 Known attacks that would affect our use? 🤔

@xuu@txt.sour.is I don’t recall where that discussion ended up being though?

@bender@twtxt.net wut da fuq?! 🤣

@xuu@txt.sour.is you mean my original idea of basically just automatically detecting Twt edits from the client side?

@xuu@txt.sour.is this is where you would need to prove that the editor delete request actually came from that feed author. Hence why integrity is much more important here.

@falsifian@www.falsifian.org without supporting dudes properly though you’re running into GDP issues and the right to forget. 🤣 we’ve had pretty lengthy discussions about this in the past years ago as well, but we never came to a conclusion. We’re all happy with.

@movq@www.uninformativ.de it would work, you are right, however, it has drawbacks, and I think in the long term would create a new set of problems that we would also then have to solve.

@david@collantes.us Hah 🤣

@prologic@twtxt.net :-D Thanks! Things can come in cycles, right? This is simply another one. Another cycle, more personal than the other “alter egos”.

@david@collantes.us We’ll get there soon™ 🔜

@david@collantes.us Hah Welcome back! 😅

@aelaraji@aelaraji.com hey, hey! You are my very first reply! 👋🏻 Cheers!

@david@collantes.us “Hello back” from the other corner of the world! 🫡

Incredibly upset—more than you could imagine—because I already made the first mistake, and corrected it (but twtxt.net got it on it’s cache, ugh!) :‘-( . Can’t wait for editing to become a reality!

Alright. My first mentions—which were picked not so randomly, LOL—are @prologic@twtxt.net, @lyse@lyse.isobeef.org, and @movq@www.uninformativ.de. I am also posting my first image too, which you see below. That’s my neighbourhood, in a “winter” day. Hopefully @prologic@twtxt.net will add my domain to his allowed list, so that the image (and any other further) renders.

Image

Alright, announce_me set to true. Now, who do I pick to be my first mention? Decisions, decisions. Next twtxt will have my first mention(s). :-)

I have configured my twtxt.txt as simple as possible. I have setup a publish_command on jenny. Hopefully all works fine, and I am good to go. Next will be setting the announce_me to true. Here we go!

Everything starts at a “hello world”. At least around these parts; the nerdy parts.

@sorenpeter@darch.dk hmm, how does your client handles “a little editing”? I am sure threads would break just as well. 😉

@prologic@twtxt.net, there is a parser bug on parent. Specifically on this portion:

"*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? 😅*"

@movq@www.uninformativ.de 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 think keeping hashes is a must. If anything for that “feels good” feeling.

@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.

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.

So.. basically a rehash of the email “unsend” requests? What if i was to make a (delete: 5vbi2ea) .. would it delete someone elses twt?

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…

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

@movq@www.uninformativ.de ooooh, nice! commit 62a2b7735749f2ff3c9306dd984ad28f853595c5:

Crawl archived feeds in –fetch-context

Like, very much! :-)

@movq@www.uninformativ.de to paraphrase US Presidents speech on each State of the Union, “the State of the Jenny is strong!” :-D As for the potential upcoming changes, there has to be a knowledgeable head honcho that will agglomerate and coalesce, and guide onto the direction that will be taken. All that with the strong input from the developers that will be implementing the changes, and a lesser (but not less valuable) input from users.

@lyse@lyse.isobeef.org I call upon the services of the @yarn_police@twtxt.net to further investigate this oddness!
