escapethe3RA: Looking for funding to maintain Monero Observer until 2026

Funding goal (24Q4+2025): 240 XMR

11 successful CCS proposals, 3500+ work hours, thousands of reports in over 3 years of thinking about, writing about, and dreaming about Monero.

That has been my sometimes rough yet always exciting secret life since 2021 and I wouldn’t change it for anything. More importantly, I owe it all to you. Thank you for supporting me since day 1 via the CCS.

Honestly… not much. Have abandon two projects (both private) on Golang and one related to cryptography. My mostly languages are Python and Javascript (also can PHP). After writing code on Go i spend same time on fixing dumb errors

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.

Recent #fiction #scifi #reading:

• The Memory Police by Yōko Ogawa. Lovely writing. Very understated; reminded me of Kazuo Ishiguro. Sort of like Nineteen Eighty-Four but not. (I first heard it recommended in comparison to that work.)

• Subcutanean by Aaron Reed; https://subcutanean.textories.com/ . Every copy of the book is different, which is a cool idea. I read two of them (one from the library, actually not different from the other printed copies, and one personalized e-book). I don’t read much horror so managed to be a little creeped out by it, which was fun.

• The Wind from Nowhere, a 1962 novel by J. G. Ballard. A random pick from the sci-fi section; I think I picked it up because it made me imagine some weird 4-dimensional effect (“from nowhere” meaning not in a normal direction) but actually (spoiler) it was just about a lot of wind for no reason. The book was moderately entertaining but there was nothing special about it.

Currently reading Scale by Greg Egan and Inversion by Aric McBay.

More thoughts about changes to twtxt (as if we haven’t had enough thoughts):

1. There are lots of great ideas here! Is there a benefit to putting them all into one document? Seems to me this could more easily be a bunch of separate efforts that can progress at their own pace:
   

1a. Better and longer hashes.

1b. New possibly-controversial ideas like edit: and delete: and location-based references as an alternative to hashes.

1c. Best practices, e.g. Content-Type: text/plain; charset=utf-8

1d. Stuff already described at dev.twtxt.net that doesn’t need any changes.

1. We won’t know what will and won’t work until we try them. So I’m inclined to think of this as a bunch of draft ideas. Maybe later when we’ve seen it play out it could make sense to define a group of recommended twtxt extensions and give them a name.

2. Another reason for 1 (above) is: I like the current situation where all you need to get started is these two short and simple documents:
   https://twtxt.readthedocs.io/en/latest/user/twtxtfile.html
   https://twtxt.readthedocs.io/en/latest/user/discoverability.html
   and everything else is an extension for anyone interested. (Deprecating non-UTC times seems reasonable to me, though.) Having a big long “twtxt v2” document seems less inviting to people looking for something simple. (@prologic@twtxt.net you mentioned an anonymous comment “you’ve ruined twtxt” and while I don’t completely agree with that commenter’s sentiment, I would feel like twtxt had lost something if it moved away from having a super-simple core.)

3. All that being said, these are just my opinions, and I’m not doing the work of writing software or drafting proposals. Maybe I will at some point, but until then, if you’re actually implementing things, you’re in charge of what you decide to make, and I’m grateful for the work.

@prologic@twtxt.net Thanks for writing that up!

I hope it can remain a living document (or sequence of draft revisions) for a good long time while we figure out how this stuff works in practice.

I am not sure how I feel about all this being done at once, vs. letting conventions arise.

For example, even today I could reply to twt abc1234 with “(#abc1234) Edit: …” and I think all you humans would understand it as an edit to (#abc1234). Maybe eventually it would become a common enough convention that clients would start to support it explicitly.

Similarly we could just start using 11-digit hashes. We should iron out whether it’s sha256 or whatever but there’s no need get all the other stuff right at the same time.

I have similar thoughts about how some users could try out location-based replies in a backward-compatible way (append the replyto: stuff after the legacy (#hash) style).

However I recognize that I’m not the one implementing this stuff, and it’s less work to just have everything determined up front.

Misc comments (I haven’t read the whole thing):

• Did you mean to make hashes hexadecimal? You lose 11 bits that way compared to base32. I’d suggest gaining 11 bits with base64 instead.

• “Clients MUST preserve the original hash” — do you mean they MUST preserve the original twt?

• Thanks for phrasing the bit about deletions so neutrally.

• I don’t like the MUST in “Clients MUST follow the chain of reply-to references…”. If someone writes a client as a 40-line shell script that requires the user to piece together the threading themselves, IMO we shouldn’t declare the client non-conforming just because they didn’t get to all the bells and whistles.

• Similarly I don’t like the MUST for user agents. For one thing, you might want to fetch a feed without revealing your identty. Also, it raises the bar for a minimal implementation (I’m again thinking again of the 40-line shell script).

• For “who follows” lists: why must the long, random tokens be only valid for a limited time? Do you have a scenario in mind where they could leak?

• Why can’t feeds be served over HTTP/1.0? Again, thinking about simple software. I recently tried implementing HTTP/1.1 and it wasn’t too bad, but 1.0 would have been slightly simpler.

• Why get into the nitty-gritty about caching headers? This seems like generic advice for HTTP servers and clients.

• I’m a little sad about other protocols being not recommended.

• I don’t know how I feel about including markdown. I don’t mind too much that yarn users emit twts full of markdown, but I’m more of a plain text kind of person. Also it adds to the length. I wonder if putting a separate document would make more sense; that would also help with the length.

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.

@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.

@movq@www.uninformativ.de

Maybe I’m being a bit too purist/minimalistic here. As I said before (in one of the 1372739 posts on this topic – or maybe I didn’t even send that twt, I don’t remember 😅), I never really liked hashes to begin with. They aren’t super hard to implement but they are kind of against the beauty of the original twtxt – because you need special client support for them. It’s not something that you could write manually in your twtxt.txt file. With @sorenpeter@darch.dk’s proposal, though, that would be possible.

Tangentially related, I was a bit disappointed to learn that the twt subject extension is now never used except with hashes. Manually-written subjects sounded so beautifully ad-hoc and organic as a way to disambiguate replies. Maybe I’ll try it some time just for fun.

@prologic@twtxt.net Brute force. I just hashed a bunch of versions of both tweets until I found a collision.

I mostly just wanted an excuse to write the program. I don’t know how I feel about actually using super-long hashes; could make the twts annoying to read if you prefer to view them untransformed.

@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!

I used to be a big fan of a service called cocalc, which you could also self host. It was kind of an integrated math, data science, research, writing, and teaching platform.

I take it back. Excalidraw is like tldraw–you can integrate it into a Javascript front end if you want. Which means technically you could self-host it if you wanted, but you’d have to write your own front end code to embed it, and host that code somehow.

@prologic@twtxt.net I see what you mean about tldraw. I looked at their github repository and it seems like they are distributing it as an npm package for people who want to include a whiteboard in their Javascript-based frontend. I didn’t see a way to just launch the thing.
