Microsoft releases Windows 11 roadmap tool to help make sense of Windows 11’s development
I’ve complained about the utter inscrutability of the Windows release process for a long time, with Microsoft seemingly using channels, build numbers, code names, date-based version numbers, and so on interchangeably, making it incredibly hard to keep track of what is being released when. It turns out even Microsoft itself started losing track, because it … ⌘ Read more

Iconography of the PuTTY tools
Ah, PuTTY. Good old reliable PuTTY. This little tool is one of those cornerstone applications in the toolbox of most of us, without any fuss, without any upsells or anti-user nonsense – it just does its job, and it has been doing its job for 30 years. Have you ever wondered, though, where PuTTY’s icons come from, how they were made, and how they evolved over time? PuTTY’s icon designs date from the late 1990s and early 2000s. They’ve never had a major stylistic redesign … ⌘ Read more

@Codebuzz@www.codebuzz.nl Speed is an issue for the client software, not the format itself, but yes I agree that it makes the most sense to append post to the end of the file. I’m referring to the definition that it’s the first url = in the file that is the one that has to be used for the twthash computation, which is a too arbitrary way of defining something that breaks treading time and time again. And this is the case for not using url+date+message = twthash.

@bender@twtxt.net It’s the experience of an ordinary person in a strange place where memories are disappearing with the help of the Memory Police. The setting feels contemporary (to the book’s 1994 publication date) rather than futuristic, except for some unexplained stuff about memories.
(#2024-09-24T12:45:54Z) @prologic@twtxt.net I’m not really buying this one about readability. It’s easy to recognize that this is a URL and a date, so you skim over it like you would we mentions and markdown links and images. If you are not suppose to read the raw file, then we might a well jam everything into JSON like mastodon
Some more arguments for a local-based treading model over a content-based one:
The format:
(#<DATE URL>)or(@<DATE URL>)both makes sense: # as prefix is for a hashtag like we allredy got with the(#twthash)and @ as prefix denotes that this is mention of a specific post in a feed, and not just the feed in general. Using either can make implementation easier, since most clients already got this kind of filtering.Having something like
(#<DATE URL>)will also make mentions via webmetions for twtxt easier to implement, since there is no need for looking up the#twthash. This will also make it possible to make 3th part twt-mentions services.Supporting twt/webmentions will also increase discoverability as a way to know about both replies and feed mentions from feeds that you don’t follow.
I demand full 9 digit nano second timestamps and the full TZ identifier as documented in the tz 2024b database! I need to know if there was a change in daylight savings as per the locality in question as of the provided date.
@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.
@movq@www.uninformativ.de I did started from scratch, today. I using am commit 6e8ce5afdabd5eac22eae4275407b3bd2a167daf (HEAD -> main, origin/main, origin/HEAD), I keep myself up-to-date, LOL. Still, that specific twtxt (o6dsrga) is no longer.

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