@alexonit@twtxt.alessandrocutolo.it Holy fuck! 🤣 I just realized how bad my typing was in my reply before 🤣 🤦‍♂️ So sorry about that haha 😆 I blame the stupid iPhone on-screen keyboard ⌨️

@zvava@twtxt.net I never used any of the social media platforms, that’s why I’m probably ignorant.

I don’t understand the concept of a retwt. Just quote the (relevant) parts from whereever and comment on that. Or post a link instead of a quote. Sounds simple enough. :-) That’s also has the benefit that it works with every source, no matter what. Since it’s called retwt, I’d imagine this to only work (well) with whatever messages the system itself offers. But I could be wrong. What would be the benefit of having a dedicated message type or structure for “hey, look at that” messages in your opinion?

Hmm, what’s a content warning?

@movq@www.uninformativ.de Holy shit, that’s insane! :-D I tried it, but i’m absolutely terrible at these type of games. I’m having trouble with the keys to move around. Maybe after ages I would pick it up and it becomes natural. I just was never a real gamer.

I will definitely try to read through the code, though! This looks sick. 8-)

Three weather services with three different forecasts. We got a little bit rained on, so at least some of them were not completely wrong. The timing was off by an hour, though. And nobody expected the Spanish inqui^W^Wthunder either. It was a nice walk.

Oh cool, as I type this, lighning and thunder very close by now. At most a kilometer away. Glad I’m home and not in the woods anymore. And heavy rain kicks in, too.

@lyse@lyse.isobeef.org Yeah, removing the cover will probably help. I’ll have to try. 😅 And, yes, the scrolling is pretty annoying (and kind of ruins the experience a little bit).

The printer isn’t that loud – at least not for a dot matrix printer. 😅 It’s been ~30 years since I’ve last seen them in person, but I remembered these things to be louder. I’m typing on my Model M, maybe that contributes to the perceived noise on this video. Here’s an isolated recording of that keyboard: https://movq.de/v/ddc98b03d8/2022-02-21–model-m-goes-brrr.ogg 🤣 It really sounds like that when you’re typing fast. Brrrrt.

I’ve got a prototype of my hardcopy simulator going. I’m typing on the keyboard and the “display” goes to the printer:

https://movq.de/v/56feb53912/s.png

https://movq.de/v/235c1eabac/MVI_8810.MOV.mp4

The biiiiiiiiiig problem is that the print head and plastic cover make it impossible to see what’s currently being printed, because this is not a typewriter. This means: In order to see what I just entered, I have to feed the paper back and forth and back and forth … it’s not ideal.

I got that idea of moving back/forth from Drew DeVault, who – as it turned out – did something similar a few years back. (I tried hard to read as little as possible of his blog post, because figuring things out myself is more fun. But that could mean I missed a great idea here or there.)

But hey, at least this is running on my Pentium 133 on SuSE Linux 6.4, printer connected with a parallel cable. 😍

(Also, yes, you can see the printouts of earlier tests and, yes, I used ed(1) wrong at one point. 🤪 And ls insisted on using colors …)

Since 2020, I’ve been putting together one playlist every year, in which each track represents one month of that year. However, I also have assigned each season two specific songs, which does not change year-to-year: Spring: “A Little Bit Of Love” by Weezer and “Gretel” by Alex G; Summer: “Dumb” by Roe Kapara and “Endless Bummer” by Weezer; Autumn: “1979” by The Smashing Pumpkins and “The Dead Come Talking” by Roe Kapara; Winter: “Red Water (Christmas Mourning)” by Type O Negative and “Christmas Time (Don’t Let The Bells End)” by The Darkness

@movq@www.uninformativ.de Are you sure?

because there is virtually no market for these devices anymore, meaning new ones are very, very expensive.

I think dot matrix printers are still pretty common in many Point of Sales (POS) registers right? At least here in AU they’re very common. I had a quick look myself today, there seems to be quite a solid market for these types of printers. In fact even EPSON still sell Dot Matrix printers themselves 🤣

@itsericwoodward@itsericwoodward.com Also just a heads up, GIF(s) aren’t supproted as an Avatar type on yarnd (what runs twtxt.net). I’d change this to something that’s more supproted like PNG, JPEG, etc.

What's Missing from "Retro"
~softwarepagan
------------------------------------------------------------------
You know, often, when I say I miss older ways of computing or
connecting online, people tell me "there's nothing stopping you
from doing that now!" and they are technicay correct in most cases
(though I can't, for example, chat with friends on MSN ever
again...) However, let me explain that while this type of thing can
*sort of* fill that hole in my heart, it isn't *the same.*

Say, for example, I wanted to connect with others over a BBS. This
wouldn't offer the same types of connections it used to. While
there are BBSes around with active users, they're no longer there
to discuss movies, Star Trek, D&D, games, etc. They're there to
discuss *BBSes.* The same can be said for Gopher, old-school forums
and all sorts of revival projects (such as Escargot, Spacehey,
etc.) Retrocomputing enthusiasts, while they have a variety of
interests, are often in these spaces to discuss the medium itself
and not other topics. This exists at a stark contrast from how
things were in the past, where a non-tech-inclined person may learn
the tech to connect with likeminded others (as I did as a
Zelda-obsessed kid.)

The same can be said of old media. People will say "well, nobody is
stopping you from watching old shows/movies now!" Again, they are
technically correct. I can go home right now and watch *Star Trek:
The Next Generation* to my heart's content. It will never again,
however, be current, or new. When something is new, it serves as a
shared cultural experience. Remember how "Game of Thrones* felt in
the mid-to-late 2010s? Yeah, that.

It's sad. I sustain myself on a mixed diet of old things, new
things, and new things intended for old millenials like me who like
old things. It can be bittersweet. 

Ah, so apparently they don’t like writing manpages anymore and instead use XML:

https://salsa.debian.org/apt-team/apt/-/blob/main/doc/apt.8.xml

And then they use XSLT on top and what not:

https://salsa.debian.org/apt-team/apt/-/blob/main/doc/manpage-style.xsl.cmake.in

It’s not even explicitly blue:

@prologic@twtxt.net haha yeah for the youtube rules i just copied the first JSON block in your screenshot (i typed it out) and it miraculously worked! yayyy

@kat@yarn.girlonthemoon.xyz @movq@www.uninformativ.de Sorry, I neither finished it nor in time. :-( That’s as good as it’s gonna get for the moment: https://git.isobeef.org/lyse/gelbariab/-/tree/master/rss-proxys?ref_type=heads

The README should hopefully provide a crude introduction. The example configuration file is documented fairly well, I believe (but maybe not). You probably still have to consult and maybe also modify the source code to fit your needs.

Let me know if you run into issues, have questions, wishes etc.

Here’s an example of X11/Xlib being old and archaic.

X11 knows the data type “cardinal”. For example, the window property _NET_WM_ICON (which holds image data for icons) is an array of “cardinal”. I am already not really familiar with that word and I’m assuming that it comes from mathematics:

https://en.wikipedia.org/wiki/Cardinal_number

(It could also be a bird, but probably not: https://en.wikipedia.org/wiki/Cardinalidae)

We would probably call this an “integer” today.

EWMH says that icons are arrays of cardinals and that they’re 32-bit numbers:

https://specifications.freedesktop.org/wm-spec/latest-single/#id-1.6.13

So it’s something like 0x11223344 with 0x11 being the alpha channel, 0x22 is red, and so on.

You would assume that, when you retrieve such an array from the X11 server, you’d get an array of uint32_t, right?

Nope.

Xlib is so old, they use char for 8-bit stuff, short int for 16-bit, and long int for 32-bit:

https://x.org/releases/current/doc/libX11/libX11/libX11.html#Obtaining_and_Changing_Window_Properties

That is congruent with the general C data types, so it does make sense:

https://en.wikipedia.org/wiki/C_data_types

Now the funny thing is, on modern x86_64, the type long int is actually 64 bits wide.

The result is that every pixel in a Pixmap, for example, is twice as large in memory as it would need to be. Just because Xlib uses long int, because uint32_t didn’t exist, yet.

And this is something that I wouldn’t know how to fix without breaking clients.

@lyse@lyse.isobeef.org @kat@yarn.girlonthemoon.xyz I spent so much time in the past figuring out if something is a dict or a list in YAML, for example.

What are the types in this example?

items:
- part_no:   A4786
  descrip:   Water Bucket (Filled)
  price:     1.47
  quantity:  4
- part_no:   E1628
  descrip:   High Heeled "Ruby" Slippers
  size:      8
  price:     133.7
  quantity:  1

items is a dict containing … a list of two other dicts? Right?

It is quite hard for me to grasp the structure of YAML docs. 😢

The big advantage of YAML (and JSON and TOML) is that it’s much easier to write code for those formats, than it is with XML. json.loads() and you’re done.

@thecanine@twtxt.net right. Spell checkers are not AI. Full grammar checking, and correction? That one I have not seeing, but on AI. So, what I meant was, let the grammar gaffes show; we type as we speak (most of the time). About spelling mistakes, well, let them be corrected as we have done since 1971(?).

@thecanine@twtxt.net @movq@www.uninformativ.de So I actually agree with you! I think Dustin is taking a bit of a “deep and dark” path here (depression), and there are many parallels to other types of activities that we can all talk to. “AI” or “LLM”(s) here should be no different. Use them, Don’t use them. I don’t really see how it takes away our creativity or critical thinking.

Honestly for these types of services, there probably isn’t much point, as the layer4 module in Caddy doesn’t do inspection/filtering anyway I think? 🤔

@kat@yarn.girlonthemoon.xyz You don’t need to change the directory first in line 11, you can just create the directory, that’s sufficient since you’re having an absolute path.

The echo in line 13 is useless, you can simplify this to: newdir="$WD/$now" If you reversed this line with the previous one, you could make use of the variable in the directory creation: mkdir "$newdir".

In line 16, pull the directory change out of the loop upfront. The loop body doesn’t modify the working directory, so no need to reset it with each cycle. In fact, you could even spare the cd altogether when you simply tell find where to look: find "$basedir" -type f….

I didn’t try it, but if I read the manpage correctly, you should be able to simplify line 19 as well:

-C Change to DIR before performing any operations. This option is order-sensitive, i.e. it affects all options that follow.

Hence, remove the cd and put the -C "$WD" as the first argument to tar. Again, I didn’t try it. Proceed with caution.

Finally, you don’t need to specify the full path to rm in line 21. I bet, /bin is in your PATH. When you removed the previous cd from my last suggestion, the relative path that follows won’t work anymore. So, just use the absolute path that you already have in a variable: rm -rf "$newdir"

I hope you find this tiny review a wee bit useful. :-)

@kat@yarn.girlonthemoon.xyz @movq@www.uninformativ.de @prologic@twtxt.net Yeah, I’m also having them in my repertoire for ages, so I’m used to the weird command line options. From today’s perspective, they’re not consistent with the rest of the typical shell utilities, that’s for sure.

Regarding find | grep foo, I recommend find -name '*foo*', prologic. Also, I regularly use -type d and -type f to find directories or files.

** Crinkly chip bags **
I usually read pretty fast. I’ve been intentionally reading Middlemarch slowly. Chapter by chapter. This forced restraint makes reading Middlemarch feel sort of religious in pace and intention.

I fell back down the type theory hole, and have once again thought to myself“what about Haskell?” and“what about algebraic data types?” These thoughts are questionable and my motivations dubious, but here I am again imagining tiny type carrying backpacks strapped to little guys — bees, beetles, and other crawlies.

Some gopher browsers handle type i and spaces better than others.

I agree with the Type i complaint below. That is just dumb.

Today I added support for Let’s Encrypt to eris via DNS-01 challenge. Updated the gcore libdns package I wrote for Caddy, Maddy and now Eris. Add support for yarn’s cache to support # type = bot and optionally # retention = N so that feeds like @tiktok@feeds.twtxt.net work like they did before, and… Updated some internal metrics in yarnd to be IMO “better”, with queue depth, queue time and last processing time for feeds.

Interesting factoid… By inspecting my “followers” list every now and again, I can tell who uses a client like jenny, tt or any other client where fetches are driven by user interactions of invoking the app. What do we call this type of client? Hmmm 🤔 Then I can tell who uses yarnd because they are “seen” more frequently 🤣

Even though I really do like the shell, I always use Dolphin to mount my digicam SD card and copy the photos onto my computer. I finally added a context menu item in Dolphin to create a forest stroll directory with the current date in order to save some typing:

Image

The following goes in ~/.local/share/kservices5/ServiceMenus/galmkdir.desktop:

[Desktop Entry]
Type=Service
X-KDE-ServiceTypes=KonqPopupMenu/Plugin,inode/directory
Actions=Waldspaziergang;

[Desktop Action Waldspaziergang]
Name=Heutigen Waldspaziergang anlegen…
Icon=folder-green
Exec=~/src/gelbariab/galmkdir "%f"

In order to update the KDE desktop cache and make this action menu item available in Dolphin, I ran:

kbuildsycoca5

The referenced galmkdir script looks like that:

#!/bin/sh
set -e

current_dir="$1"
if [ -z "$current_dir" ]; then
    echo "Usage: $0 DIRECTORY" >&2
    exit 1
fi

dir="$(kdialog \
    --geometry 350x50 \
    --title "Heutigen Waldspaziergang anlegen" \
    --inputbox "Neues Verzeichnis in „$current_dir“ anlegen:" \
    "waldspaziergang-$(date +%Y-%m-%d)")"
mkdir "$current_dir/$dir"
dolphin "$current_dir/$dir"

This solution is far from perfect, though. Ideally, I’d love to have it in the “Create New” menu instead of the “Actions” menu. But that doesn’t really work. I cannot define a default directory name, not to mention even a dynamic one with the current date. (I would have to update the .desktop file every day or so.) I also failed to create an empty directory. I somehow managed to create a directory with some other templates in it for some reason I do not really understand.

Let’s see how that works out in the next days. If I like it, I might define a few more default directory names.

@eapl.me@eapl.me Interesting! Two points stood right out to me:

1. Why the hell are e-mail newsletters considered a valid option in the first place? Just offer an Atom feed and be done with it! Especially for a blog of this very type. This doesn’t even involve a third party service. Although, in addition he also links to Feedburner, what the fuck!? No e-mail address or the like is needed and subject to being disclosed.

2. When these spam mailers want to prevent resubscribing, then for fuck’s sake, why don’t they use a hash of the e-mail address (I saw that in yarnd) for that purpose? Storing the e-mail address in clear text after unsubscribing is illegal in my book.

@movq@www.uninformativ.de Oh, right, a type would be good to have! :-D

@lyse@lyse.isobeef.org (I think of pointers as “memory location + type”, but I have done so much C and Assembler by now that the whole thing feels almost trivial to me. And I would have trouble explaining these concepts, I guess. 😅 Maybe I’ll cover this topic with our new Azubis/trainees some day …)

It’s extremely surprising to me that younger non-technical people just type in their full name (properly cased first and last name with a space in between) for a technical username in account registration or login forms. I’ve seen that happening several times in the past few years. The field name is “Benutzername” in German, literally “username”. Even adding a placeholder text to signal that they could simply use their nickname in lowercase did not change anything at all. Well, one person used at least an e-mail address.

This wasn’t the case six, seven years ago, everybody had some “real” username. Even non-techies. It looks like some “common knowledge” is getting lost. Strange. Very weird. It trips me every time I see it.

Have you experienced something similar?

Thanks, @xuu@txt.sour.is, great explanation. In another project I’ve structured it exactly like you wrote. The mock storage over there extends the SQLite storage and provides mechanism to return errors and such for testing purposes:

• storage/ defines the interface
  
  • sqlite/ implements the storage interface
    
  • mock/ extends the SQLite implementation by some mocking capabilities and assertions
    

Here, however, there are no storage subpackages. It’s just storage, that’s it. Everything is in there. The only implementation so far is an SQLite backend that resides in storage. My RAM storage is exactly that SQLite storage, but with :memory: instead a backing file on disk. I do not have a mock storage (yet).

I have to think about it a bit more, but I probably have to do exactly that in my tt rewrite, too. Sigh. I just have the feeling that in storage/sqlite/sqlite_test.go I cannot import storage/mock for the helper because storage/mock/mock.go imports and embeds the type from storage/sqlite. But I’m too tired right now to think clearly.

ChatGPT works with just about any document type that you might be working with or come across in the world of tech and computers, including .pdf, .doc, .docx, .txt, .rtf, .xls, .xlsx, .csv, … Read More ⌘ Read more

@xuu@txt.sour.is My layout looks like this:

• storage/
  
  • storage.go: defines a Storage interface
    
  • sqlite.go: implements the Storage interface
    
  • sqlite_test.go: originally had a function to set up a test storage to test the SQLite storage implementation itself: newRAMStorage(testing.T, $initialData) *Storage
    
• controller/
  
  • feeds.go: uses a Storage
    
  • feeds_test.go: here I wanted to reuse the newRAMStorage(…) function
    

I then tried to relocate the newRAMStorage(…) into a

• teststorage/
  
  • storage.go: moved here as NewRAMStorage(…)
    

so that I could just reuse it from both

• storage/
  
  • sqlite_test.go: uses testutils.NewRAMStorage(…)
    
• controller/
  
  • feeds_test.go: uses testutils.NewRamStorage(…)
    

But that results into an import cycle, because the teststorage package imports storage for storage.Storage and the storage package imports testutils for testutils.NewRAMStorage(…) in its test. I’m just screwed. For now, I duplicated it as newRAMStorage(…) in controller/feeds_test.go.

I could put NewRAMStorage(…) in storage/testutils.go, which could be guarded with //go:build testutils. With go test -tags testutils …, in storage/sqlite_test.go could just use NewRAMStorage(…) directly and similarly in controller/feeds_test.go I could call storage.NewRamStorage(…). But I don’t know if I would consider this really elegant.

The more I think about it, the more appealing it sounds. Because I could then also use other test-related stuff across packages without introducing other dedicated test packages. Build some assertions, converters, types etc. directly into the same package, maybe even make them methods of types.

If I went that route, I might do the opposite with the build tag and make it something like !prod instead of testing. Only when building the final binary, I would have to specify the tag to exclude all the non-prod stuff. Hmmm.

it seems to be confused with the subject right next to it.. it works better at the end of the twt string.
Yarn won’t display anything. but the parser does add it to the AST in a way that you can parse it out using twt.Attrs().Get("lang")

@andros@twtxt.andros.dev Just before the pandemic, we watched Uncle Bob videos once a week in the lunch break. While almost all of my old teammates agreed with his views, I partially found them to be very odd and even counterproductive.

I didn’t come across John Ousterhout or any of his work before, at least not deliberately. So, this document is my first contact.

I only finished the chapter on comments and I totally agree with John so far. This document just manifests to me how weird Bob’s view is on certain subjects.

I always disagreed with the concept of a maximum method length. Sure, generally, shorter functions are probably better, but it always depends. And I’ve certainly seen super short methods that just made the code flow even worse to follow. While “one function should only do one thing” is a nice general rule, I’m 100% in team John with the shown examples. There are cases, where this doesn’t help readability at all. Not even close.

To me, a function always has to justify its existence. Either by reusing it at least at another place or by coming up with dedicated tests for it. But if it is just called once and there are no tests, I almost always decide against it. Personally, I don’t mind longer methods. We just recently had a discussion about that and I lost against two other workmates who are more in Uncle Bob’s camp, they refactored one medium sized method into three very short ones. Luckily, we agree on most other topics.

Lol, what!? The shorter the method, the longer the variables inside? I first thought I misread or the writeup mixed it up. I’ll always do it the other way around.

I’ve been also bitten badly by outdated comments in the past, but Bob must have worked on really terrible projects to end up with such an attitude to dislike comments. Oh well. No doubt, I’ve come across by several orders of magnitude more useless comments, in my experience (autogenerated) JavaDocs fall in the category more frequently than not. So, I know that there are different types of comments. A comment doesn’t automatically mean that it is good and justified.

But I also partially agree with Bob and John and think that a good name has a proper chance to save a comment. Though, when in doubt, I go John’s route and use a shorter name with a comment rather than use a kilometer long identifier. Writing good comments typically takes some time, sometimes much longer than writing the code. It regularly takes me several minutes. It’s a hard art.

I perhaps should read up on John’s work. He seems to be more reasonable and likeminded. :-) Let me continue to complete this document.

@prologic@twtxt.net Of course you don’t notice it when yarnd only shows at most the last n messages of a feed. As an example, check out mckinley’s message from 2023-01-09T22:42:37Z. It has “[Scheduled][Scheduled][Scheduled]“… in it. This text in square brackets is repeated numerous times. If you search his feed for closing square bracket followed by an opening square bracket (][) you will find a bunch more of these. It goes without question he never typed that in his feed. My client saves each twt hash I’ve explicitly marked read. A few days ago, I got plenty of apparently years old, yet suddenly unread messages. Each and every single one of them containing this repeated bracketed text thing. The only conclusion is that something messed up the feed again.

Breaked my fdroid repo by machinally type rm -rf repo in /var/www/fdroid. Hope it just contain apks and icons and i can recover

@prologic@twtxt.net maybe you meant to specify twtxt as a type similar to ActivityPub’s application/activity+json in https://webfinger.net/lookup/?resource=sorenpeter@norrebro.space

    {
      "rel": "self",
      "type": "application/activity+json",
      "href": "https://norrebro.space/users/sorenpeter"
    },

Then it would also make sense to define a Link Relations but should that then link to something like https://twtxt.dev/webfinger.html where we can describe the spec?

@eapl.me@eapl.me why not https://domain.com/.well-known/twtxt/:domain/:user ?

the business card test is this can you write it on your business card and have someone you give it to be able to figure it out without added context?

• phone number: yes because everyone knows what a phone number is.
  
• email address: yes, everyone knows an email and their aol or prodigy will let them email.
  
• twitter/x/insta/pintrest handle: no, whats a twitter? do i need to sign up?
  
• domain name: yes its simple and you just type it in a browser right?
  
• twtxt url: kinda? its a bit long and is that a forward slash? or a backward slash?

One benefit with bluesky is your username is also a website. And not a clunky URL with slashes and such. I wish twtxt adopted that. I have advocated for webfinger to for twtxt to let us do something like it with usernames. Nostr has something like it

By default the bsky.social urls all redirect to their feeds like: hmpxvt.bsky.social
Many custom urls will redirect to some kind of linktree or just their feed cwebonline.com or la.bonne.petite.sour.is or if you are a major outlet just to your web presence like https://theonion.com‬ or https://netflix.com

Its just good SEO practice

Do all nostr addresses take you to the person if typed into a browser? That is the secret sauce.
No having to go to some random page first. no accounts. no apps to install. just direct to the person.

@bender@twtxt.net @prologic@twtxt.net I’m not exactly asking yarnd to change. If you are okay with the way it displayed my twts, then by all means, leave it as is. I hope you won’t mind if I continue to write things like 1/4 to mean “first out of four”.

What has text/markdown got to do with this? I don’t think Markdown says anything about replacing 1/4 with ¼, or other similar transformations. It’s not needed, because ¼ is already a unicode character that can simply be directly inserted into the text file.

What’s wrong with my original suggestion of doing the transformation before the text hits the twtxt.txt file? @prologic@twtxt.net, I think it would achieve what you are trying to achieve with this content-type thing: if someone writes 1/4 on a yarnd instance or any other client that wants to do this, it would get transformed, and other clients simply wouldn’t do the transformation. Every client that supports displaying unicode characters, including Jenny, would then display ¼ as ¼.

Alternatively, if you prefer yarnd to pretty-print all twts nicely, even ones from simpler clients, that’s fine too and you don’t need to change anything. My 1/4 -> ¼ thing is nothing more than a minor irritation which probably isn’t worth overthinking.

@prologic@twtxt.net I’m not a yarnd user, so it doesn’t matter a whole lot to me, but FWIW I’m not especially keen on changing how I format my twts to work around yarnd’s quirks.

I wonder if this kind of postprocessing would fit better between composing (via yarnd’s UI) and publishing. So, if a yarnd user types ¼, it could get changed to ¼ in the twtxt.txt file for everyone to see, not just people reading through yarnd. But when I type ¼, meaning first out of four, as a non-yarnd user, the meaning wouldn’t get corrupted. I can always type ¼ directly if that’s what I really intend.

(This twt might be easier to understand if you read it without any transformations :-P)

Anyway, again, I’m not a yarnd user, so do what you will, just know you might not be seeing exactly what I meant.

@2024-10-08T19:36:38-07:00@a.9srv.net Thanks for the followup. I agrees with most of it - especially:

Please nobody suggest sticking the content type in more metadata. 🙄

Yes, URL can be considered ugly, but they work and are understandable by both humans and machines. And its trivial for any client to hide the URLs used as reference in replies/treading.

Webfinger can be an add-on to help lookup people, and it can be made independent of the nick by just serving the same json regardless of the nick as people do with static sites and a as I implemented it on darch.dk (wf endpoint). Try RANDOMSTRING@darch.dk on http://darch.dk/wf-lookup.php (wf lookup) or RANDOMSTRING@garrido.io on https://webfinger.net

@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

$ echo -e "https://example.com 2024-09-29T13:30:00Z Hello World!" | sha256sum - | awk '{ print $1 }' | base64 | head -c 12

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.

@lyse@lyse.isobeef.org I’d suggest making the whole content-type thing a SHOULD, to accommodate people just using some hosting service they don’t have much control over. (The same situation could make detecting followers hard, but IMO “please email me if you follow me” is still legit twtxt, even if inconvenient.)

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…

@lyse@lyse.isobeef.org Sorry, I don’t think I ever had charset=utf8. I just noticed that a few days ago. OpenBSD’s httpd might not support including a parameter with the mime type, unfortunately. I’m going to look into it.

Now WTF!? Suddenly, @falsifian@www.falsifian.org’s feed renders broken in my tt Python implementation. Exactly what I had with my Go rewrite. I haven’t touched the Python stuff in ages, though. Also, tt and tt2 do not share any data at all.

By any chance, did you remove the ; charset=utf-8 from your Content-Type: text/plain header, falsifian?

Image

@movq@www.uninformativ.de Non-ASCII characters were broken. Like U+2028, degrees (°), etc.

Turns out I used a silly library to detect the encoding and transform to UTF-8 if needed. When there is no Content-Type header, like for local files, it looks at the first 1024 bytes. Since it only saw ASCII in that region, the damn thing assumed the data to be in Windows-1252 (which for web pages kinda makes sense):

// TODO: change default depending on user's locale?
return charmap.Windows1252, "windows-1252", false

https://cs.opensource.google/go/x/net/+/master:html/charset/charset.go;l=102

This default is hardcoded and cannot be changed.

Trying to be smart and adding automatic support for other encodings turned out to be a bad move on my end. At least I can reduce my dependency list again. :-)

I now just reject everything that explicitly specifies something different than text/plain and an optional charset other than utf-8 (ignoring casing). Otherwise I assume it’s in UTF-8 (just like the twtxt file format specification mandates) and hope for the best.
