For some reason, I was using calc all this time. I mean, it’s good, but I need to do base conversions (dec, hex, bin) very often and you have to type base(2) or base(16) in calc to do that. That’s exhausting after a while.

So I now replaced calc with a little Python script which always prints the results in dec/hex/bin, grouped in bytes (if the result is an integer). That’s what I need. It’s basically just a loop around Python’s exec().

$ mcalc

all of the software sucks, but i have a solution! we’ll write even more software! get more people involved, make it the Ideal Career, then we can write AL̵L̴ O̵F TH̨E ̧C̀ODE̷S. mountains of shitty garbage that kind-of does the thing. software will still suck, but T͜HE̕N oh then we can write compilers that let us run the old shitty code inside of our mountain of new shitty code. now all of the code is in a giant pile and we’re using it to control space ships that definitely never crash. the more code the better! we can represent NaN easily in undefined systems! developers aren’t particularly bright, so the language is simple and easy for them to understand. we know this, that’s why it was made this way. the͡ moun͢tain ͠m̵us͜t ͠nȩver̢ ̴wa̡ve̴r̵. the more code the better. so instead of writing the code manually we c̴ómpilę t͞or̸t̕u͜red so̷u͜ls ͏i͞n͞to͝ ͟nice ͢b̀l̷oxe̡ls ̸of͠ ̸t̶an̡g͜l̀ed ͞n̢eu͏ra̡l͠ ̕ne̢t͏w͟orkś.̸ w̨e d͠on’t́ know how i̵t ̷w͟ork̡s, ̴but ̷t̴he model̢ ̶is̛ 5̛0GiB ́s̶o ͟i͞t s͞e͘rve͟s ̴tḩe̛ purpośe.

New post (mostly follow-up on the previous with a few new points) on the twtxt v2 discussion. http://a.9srv.net/b/2024-10-08

This is only first draft quality, but I made some notes on the #twtxt v2 proposal. http://a.9srv.net/b/2024-09-25

Sorry but i dont undestand b. New feed author? But why?

@movq@www.uninformativ.de @falsifian@www.falsifian.org @prologic@twtxt.net Maybe I don’t know what I’m talking about and You’ve probably already read this: Everything you need to know about the “Right to be forgotten” coming straight out of the EU’s GDPR Website itself. It outlines the specific circumstances under which the right to be forgotten applies as well as reasons that trump the one’s right to erasure …etc.

I’m no lawyer, but my uneducated guess would be that:

A) twts are already publicly available/public knowledge and such… just don’t process children’s personal data and MAYBE you’re good? Since there’s this:

… an organization’s right to process someone’s data might override their right to be forgotten. Here are the reasons cited in the GDPR that trump the right to erasure:

• The data is being used to exercise the right of freedom of expression and information.
  
• The data is being used to perform a task that is being carried out in the public interest or when exercising an organization’s official authority.
  
• The data represents important information that serves the public interest, scientific research, historical research, or statistical purposes and where erasure of the data would likely to impair or halt progress towards the achievement that was the goal of the processing.
  

B) What I love about the TWTXT sphere is it’s Human/Humane element! No deceptive algorithms, no Corpo B.S …etc. Just Humans. So maybe … If we thought about it in this way, it wouldn’t heart to be even nicer to others/offering strangers an even safer space.
I could already imagine a couple of extreme cases where, somewhere, in this peaceful world one’s exercise of freedom of speech could get them in Real trouble (if not danger) if found out, it wouldn’t necessarily have to involve something to do with Law or legal authorities. So, If someone asks, and maybe fearing fearing for… let’s just say ‘Their well being’, would it heart if a pod just purged their content if it’s serving it publicly (maybe relay the info to other pods) and call it a day? It doesn’t have to be about some law/convention somewhere … 🤷 I know! Too extreme, but I’ve seen news of people who’d gone to jail or got their lives ruined for as little as a silly joke. And it doesn’t even have to be about any of this.

P.S: Maybe make X tool check out robots.txt? Or maybe make long-term archives Opt-in? Opt-out?
P.P.S: Already Way too many MAYBE’s in a single twt! So I’ll just shut up. 😅

One distinct disadvantage of (replyto:…) over (edit:#): (replyto:…) relies on clients always processing the entire feed – otherwise they wouldn’t even notice when a twt gets updated. a) This is more expensive, b) you cannot edit twts once they get rotated into an archived feed, because there is nothing signalling clients that they have to re-fetch that archived feed.

I guess neither matters that much in practice. It’s still a disadvantage.

@mckinley@twtxt.net

HTTPS is supposed to do [verification] anyway.

TLS provides verification that nobody is tampering with or snooping on your connection to a server. It doesn’t, for example, verify that a file downloaded from server A is from the same entity as the one from server B.

I was confused by this response for a while, but now I think I understand what you’re getting at. You are pointing out that with signed feeds, I can verify the authenticity of a feed without accessing the original server, whereas with HTTPS I can’t verify a feed unless I download it myself from the origin server. Is that right?

I.e. if the HTTPS origin server is online and I don’t mind taking the time and bandwidth to contact it, then perhaps signed feeds offer no advantage, but if the origin server might not be online, or I want to download a big archive of lots of feeds at once without contacting each server individually, then I need signed feeds.

feed locations [being] URLs gives some flexibility

It does give flexibility, but perhaps we should have made them URIs instead for even more flexibility. Then, you could use a tag URI, urn:uuid:*, or a regular old URL if you wanted to. The spec seems to indicate that the url tag should be a working URL that clients can use to find a copy of the feed, optionally at multiple locations. I’m not very familiar with IP{F,N}S but if it ensures you own an identifier forever and that identifier points to a current copy of your feed, it could be a great way to fix it on an individual basis without breaking any specs :)

I’m also not very familiar with IPFS or IPNS.

I haven’t been following the other twts about signatures carefully. I just hope whatever you smart people come up with will be backwards-compatible so it still works if I’m too lazy to change how I publish my feed :-)

@prologic@twtxt.net well…

how would that work exactly?

To my limited knowledge, Keyoxide is an open source project offering different tools for verifying one’s online persona(s). That’s done by either A) creating an Ariande Profile using the web interface, a CLI. or B) Just using your GPG key. Either way, you add in Identity claims to your different profiles, links and whatnot, and finally advertise your profile … Then there is a second set of Mobile/Web clients and CLI your correspondents can use to check your identity claims. I think of them like the front-ends of GPG Keyservers (which keyoxide leverages for verification when you opt for the GPG Key method), where you verify profiles using links, Key IDs and Fingerprints…

Who maintains cox site? Is it centralized or decentralized can be relied upon?

• Maintainers? Definitely not me, but here’s their Git stuff and OpenCollective page …
  
• Both ASP and Keyoxide Webtools can be self-hosted. I don’t see a central authority here… + As mentioned on their FAQ page the whole process can be done manually, so you don’t have to relay on any one/thing if you don’t want to, the whole thing is just another tool for convenience (with a bit of eye candy).
  

Does that mean then that every user is required to have a cox side profile?

Nop. But it looks like a nice option to prove that I’m the same person to whom that may concern if I ever change my Twtxt URL, host/join a yarn pod or if I reach out on other platforms to someone I’ve met in her. Otherwise I’m just happy exchanging GPG keys or confirm the change IRL at a coffee shop or something. 😁

@movq@www.uninformativ.de @prologic@twtxt.net Hey! I may have found a silly trick to announce my following to people hosting their feeds on the Gemini space using the requested URI itself instead of relaying on the USER Agent 😂. I’ve copied my current feed over to my (to be) Gemlog for testing. And if I do a jenny -D "gemini://gem.aelaraji.com/twtxt.txt?follower=aelaraji@https://aelaraji.com/twtxt.txt" and this happens:

A) As a follower, I get the feed as usual.
B) As the feed owner, I get this in logs:

hostname:1965 - “gemini://gem.aelaraji.com/twtxt.txt?follower=aelaraji@https://aelaraji.com/twtxt.txt” 20 “text/plain;lang=en-US”

You could do the same for Gopher feeds but only if you want to announce yourself by throwing in an error in their logs, then you’ll need a second request to fetch the feed. jenny -D "gopher://gopher.aelaraji.com/twtxt.txt&follower=aelaraji@https:/aelaraji.com/twtxt.txt" gave me this :

gopher.aelaraji.com:70 - [09/Sep/2024:22:08:54 +0000] “GET 0/twtxt.txt&follower=aelaraji@https:/aelaraji.com/twtxt.txt HTTP/1.0” 404 0 “” “Unknown gopher client”

NB: the follower=... string won’t appear in gopher logs after a ? but if I replace it with a + or a & and it works. There will be a missing / after the https:. Probably a client thing.

@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.

@prologic@twtxt.net I’ve just went in a case b) on @abucci@anthony.buc.ci ’s pod, if I click on their nickname I get a Log-in page. And if I click on anyone else’s I a profile page. Is that normal?

I’m happy with the current implementation though, because the only reason you should be hitting the external profile endpoint at all is a) you’re logged in and happen to click on someone’s profile that is external to the pod or b) you’re anonymous and just clicking through the frontpage (see a)

@bender@twtxt.net What multiplexer do you use? I usually use Tmux and have my prefix mapped to C-a on my local machine and the default C-b on the remote ones so they don’t conflict if it helps.

So Youtube rea really cracking down on Ad-blockers. The new popup is a warning saying you can watch 3 videos before you can watch no more. Not sure for how long. I guess my options are a) wait for the ad-blockers to catch-up b) pay for Youtube c) Stop using Youtube.

I think I’m going with c) Stop using Youtube.

I don’t really like the term “gatekeeping”, especially when it’s used to describe the general concept of a barrier to entry. The term “gatekeeping” implies to me a “gatekeeper”–a person A who is trying to control if person B can interact with person C. It implies active discrimination, perhaps even bigotry, when in reality the barrier might be a passive issue such as scarcity or inherent complexity. “Gatekeeping” seems an intentionally- and needlessly-charged term.

I’ve seen BlueSky referred to as BS (as in Blue Sky, but you know…), which seems apt.

CEO is a cryptocurrency fool, as is Jack Dorsey, so I don’t expect much from it. Then again I’m old and refuse to join any new hotness so take my curmudgeonly opinions with a grain of salt.

I read somewhere or another that the “decentralization” is only going to be there so that they can push content moderation onto users. They will happily welcome Nazis and fascists, leaving it up to end users to block those instances.

I wonder how they plan to handle the 4chan-level stuff, since that will surely come.

I have found the issue with this very subtle bug.. the cache was returning a slice that would be mutated. The mutation involved appending an item and then sorting. because the returned slice is just a pointer+length the sort would modify the same memory.

          CACHE         Returned slice          
original: [A B C D]     [A B C D]
add:      [A B C D] E   [A B C D E]
sort:     [E A B C] D   [A B C D E]

I use IP over Alternating Current at home. The only issue is the bridges forget device MACs sometimes and I get weird states where I can ping a deviceA and the the internet from deviceB. But deviceA can only ping device B even though they are on the same subnet and default gateway.

The problem I have with the vast majority of social movements, left or right, is that they often lead to projection instead of introspection. Instead of person A trying to decide how person B can treat person C better, person A should try to decide how person A can treat person C better.
