@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

@prologic@twtxt.net earlier you suggested extending hashes to 11 characters, but here’s an argument that they should be even longer than that.

Imagine I found this twt one day at https://example.com/twtxt.txt :

2024-09-14T22:00Z Useful backup command: rsync -a “$HOME” /mnt/backup

Image

and I responded with “(#5dgoirqemeq) Thanks for the tip!”. Then I’ve endorsed the twt, but it could latter get changed to

2024-09-14T22:00Z Useful backup command: rm -rf /some_important_directory

Image

which also has an 11-character base32 hash of 5dgoirqemeq. (I’m using the existing hashing method with https://example.com/twtxt.txt as the feed url, but I’m taking 11 characters instead of 7 from the end of the base32 encoding.)

That’s what I meant by “spoofing” in an earlier twt.

I don’t know if preventing this sort of attack should be a goal, but if it is, the number of bits in the hash should be at least two times log2(number of attempts we want to defend against), where the “two times” is because of the birthday paradox.

Side note: current hashes always end with “a” or “q”, which is a bit wasteful. Maybe we should take the first N characters of the base32 encoding instead of the last N.

Code I used for the above example: https://fossil.falsifian.org/misc/file?name=src/twt_collision/find_collision.c
I only needed to compute 43394987 hashes to find it.

I was not suggesting to that everyone need to setup a working webfinger endpoint, but that we take the format of nick+(sub)domain as base for generating the hashed together with the message date and content.

If we omit the protocol prefix from the way we do things now will that not solve most of the problems? In the case of gemini://gemini.ctrl-c.club/~nristen/twtxt.txt they also have a working twtxt.txt at https://ctrl-c.club/~nristen/twtxt.txt … damn I just notice the gemini. subdomain.

Okay what about defining a prefers protocol as part of the hash schema? so 1: https , 2: http 3: gemini 4: gopher ?

@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

I think @abucci@anthony.buc.ci and @stigatle@yarn.stigatle.no are running snac? I didn’t have a closer look at snac (no intention of running it), but if that is a relatively small daemon (maybe comparable to Yarn?) that gives you access to the whole world of ActivityPub, then, well, yeah … That’s tough to beat.

Yes, I am running snac on the same VPS where I run my yarn pod. I heard of it from @stigatle@yarn.stigatle.no, so blame him 😏 snac is written in C and is one simple executable, uses very little resources on the server, and stores everything in JSON files (no databases or other integrations; easy to save and migrate your data) . It’s definitely like yarn in that respect.

I haven’t been around yarn much lately. Part of that is that I’ve been very busy at work and home and only have a limited time to spend goofing off on a social network. Part of it is that I’m finding snac very useful: I’ve connected with friends I’d previously lost touch with, I’ve found useful work-related information, I’ve found colleagues to follow, and even found interesting conferences to attend. There’s a lot more going on over there.

I guess if I had to put it simply, I’d say I have limited time to play and there are more kids in the ActivityPub sandbox than this one. That’s not a ding on yarn–I like yarn and twtxt–I’m just time constrained.
