There’s a simple reason all the current hashes end in a or q: the hash is 256 bits, the base32 encoding chops that into groups of 5 bits, and 256 isn’t divisible by 5. The last character of the base32 encoding just has that left-over single bit (256 mod 5 = 1).

So I agree with #3 below, but do you have a source for #1, #2 or #4? I would expect any lack of variability in any part of a hash function’s output would make it more vulnerable to attacks, so designers of hash functions would want to make the whole output vary as much as possible.

Other than the divisible-by-5 thing, my current intuition is it doesn’t matter what part you take.

1. Hash Structure: Hashes are typically designed so that their outputs have specific statistical properties. The first few characters often have more entropy or variability, meaning they are less likely to have patterns. The last characters may not maintain this randomness, especially if the encoding method has a tendency to produce less varied endings.

2. Collision Resistance: When using hashes, the goal is to minimize the risk of collisions (different inputs producing the same output). By using the first few characters, you leverage the full distribution of the hash. The last characters may not distribute in the same way, potentially increasing the likelihood of collisions.

3. Encoding Characteristics: Base32 encoding has a specific structure and padding that might influence the last characters more than the first. If the data being hashed is similar, the last characters may be more similar across different hashes.

4. Use Cases: In many applications (like generating unique identifiers), the beginning of the hash is often the most informative and varied. Relying on the end might reduce the uniqueness of generated identifiers, especially if a prefix has a specific context or meaning.

Taking the last n characters of a base32 encoded hash instead of the first n can be problematic for several reasons:

1. Hash Structure: Hashes are typically designed so that their outputs have specific statistical properties. The first few characters often have more entropy or variability, meaning they are less likely to have patterns. The last characters may not maintain this randomness, especially if the encoding method has a tendency to produce less varied endings.

2. Collision Resistance: When using hashes, the goal is to minimize the risk of collisions (different inputs producing the same output). By using the first few characters, you leverage the full distribution of the hash. The last characters may not distribute in the same way, potentially increasing the likelihood of collisions.

3. Encoding Characteristics: Base32 encoding has a specific structure and padding that might influence the last characters more than the first. If the data being hashed is similar, the last characters may be more similar across different hashes.

4. Use Cases: In many applications (like generating unique identifiers), the beginning of the hash is often the most informative and varied. Relying on the end might reduce the uniqueness of generated identifiers, especially if a prefix has a specific context or meaning.

In summary, using the first n characters generally preserves the intended randomness and collision resistance of the hash, making it a safer choice in most cases.

@quark@ferengi.one Do you mean something like this?

$ ./yarnc debug ~/Public/twtxt.txt | tail -n 1
kp4zitq 2024-09-08T02:08:45Z	(#wsdbfna) @<aelaraji https://aelaraji.com/twtxt.txt> My work has this thing called "compressed work", where you can **buy** extra time off (_as much as 4 additional weeks_) per year. It comes out of your pay though, so it's not exactly a 4-day work week but it could be useful, just haven't tired it yet as I'm not entirely sure how it'll affect my net pay

@prologic@twtxt.net I saw those, yes. I tried using yarnc, and it would work for a simple twtxt. Now, for a more convoluted one it truly becomes a nightmare using that tool for the job. I know there are talks about changing this hash, so this might be a moot point right now, but it would be nice to have a tool that:

1. Would calculate the hash of a twtxt in a file.
   
2. Would calculate all hashes on a twtxt.txt (local and remote).
   

Again, something lovely to have after any looming changes occur.

@bender@twtxt.net LOL normally things (in the vanilla template) render like <time class="dt-published" datetime="2024-09-17T15:05:19+01:00"> 2024-09-17 14:05:19 +0000 UTC+0000 </time> the datetime=... atribute is in my local time UTC+1 then the text within the tag is in UTC+0

The thing is, I’ve been poking at the template as well, but nothing changes. I literally whole portionsm added in lorem text just to see if it would do anything, then twtxt2html -T ./layout.html <link to twtxt file> | less shows same thing as before! nothing changes. LOL I’m not sure I’m going at it the right way.

@movq@www.uninformativ.de I didn’t run the command as you recommended, but, I wiped things once more, and ran jenny -f, and this time got:

Subject: The [tag URI scheme](https://en.wikipedia.org/wiki/Tag_URI_scheme) looks interesting. I like that it human read- and writable. And since we already got the timestamp in the twtxt.txt it would be

Notice the difference? Soren edited, and broke everything.

@mckinley@twtxt.net Thanks for the feedback.

1. Yeah I agrees that nick sound not be part of syntax. Any valid URL to a twtxt.txt-file should be enough and is more clear, so it is not confused with a email (one of the the issues with webfinger and fedivese handles)
   
2. I think any valid URL would work, since we are not bound to look for exact matches. Accepting both http and https as well as a gemni and gophe could all work as long as the path to the twtxt.txt is the same.
   
3. My idea is that you quote the timestamp as it is in the original twtxt.txt that you are referring to, so you can do it by simply copy/pasting. Also what are the change that the same human will make two different posts within the same second?!
   

Regarding the whole cryptographic keys for identity, to me it seems like an unnecessary layer of complexity. If you move to a new house or city you tell people that you moved - you can do the same in a twtxt.txt. Just post something like “I move to this new URL, please follow me there!” I did that with my feeds at least twice, and you guys still seem to read my posts:)

Weird, I can’t set up my iwm0 interface to rdomain 1 : ifconfig: SIOCSIFRDOMAIN: Invalid argument. What am I missing? #openbsd

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 ?

@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.

@falsifian@www.falsifian.org In my opinion it was a mistake that we defined the first url field in the feed to define the URL for hashing. It should have been the last encountered one. Then, assuming append-style feeds, you could override the old URL with a new one from a certain point on:

# url = https://example.com/alias/txtxt.txt
# url = https://example.com/initial/twtxt.txt
<message 1 uses the initial URL>
<message 2 uses the initial URL, too>
# url = https://example.com/new/twtxt.txt
<message 3 uses the new URL>
# url = https://example.com/brand-new/twtxt.txt
<message 4 uses the brand new URL>

In theory, the same could be done for prepend-style feeds. They do exist, I’ve come around them. The parser would just have to calculate the hashes afterwards and not immediately.

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

1. 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.

2. 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.)

On the Subject of Feed Identities; I propose the following:

1. Generate a Private/Public ED25519 key pair
   
2. Use this key pair to sign your Twtxt feed
   
3. Use it as your feed’s identity in place of # url = as # key = ...
   

For example:

$ ssh-keygen -f prologic@twtxt.net
$ ssh-keygen -Y sign -n prologic@twtxt.net -f prologic@twtxt.net twtxt.txt

And your feed would looke like:

# nick        = prologic
# key         = SHA256:23OiSfuPC4zT0lVh1Y+XKh+KjP59brhZfxFHIYZkbZs
# sig         = twtxt.txt.sig
# prev        = j6bmlgq twtxt.txt/1
# avatar      = https://twtxt.net/user/prologic/avatar#gdoicerjkh3nynyxnxawwwkearr4qllkoevtwb3req4hojx5z43q

Twt Hash extension would change of course to use a feed’s ED25519 public key fingerprint.

1. Pull the latest version from git (I have commit 7ad848, same as on twtxt.net I believe).
   
2. make build and make install
   
3. Restart yarnd
   
4. Refresh cache in Poderator Settings
   

Yet I still see these bogus /external things on my pod when I hit URLs like the one I sent you recently. When I hit such a URL with curl I think it’s giving an error? But in a web browser, the (buggy) response is the same as it was before I updated.

So, this problem is not fixed for me.

You might have seen me popping up on IRC. This is how it looks:

That’s EZirc from the 1990ies. (It says it needs Warp 4, but runs fine on Warp 3.)

Lots of this old stuff still works (technically), but as @lyse@lyse.isobeef.org said: A lot of it really is dead. There’s not much going on anymore in Usenet.

i was actually planning on running at a 11:00 or so pace, but felt so good i just kept increasing the pace each ¼ - ½ mile. in my own little world and ended it feeling great. hopefully i am not peaking too early again… just 12 more days until the PTC!

HTTP/2 differs from 1.x by becoming a binary protocol, it also multiplexes multiple channels over the same connection and has the ability to prefetch related content to the browser to lower the perceived latency.

HTTP/3 moves the binary protocol from HTTP/2 over to QUIC which is based on UDP instead of TCP. This makes it better suited to mobile or unstable networks where handling of transmission errors can be handled at a higher level.

Does anyone know what the differences between HTTP/1.1 HTTP/2 and HTTP/3 are? 🤔

@prologic@twtxt.net The headline is interesting and sent me down a rabbit hole understanding what the paper (https://aclanthology.org/2024.acl-long.279/) actually says.

The result is interesting, but the Neuroscience News headline greatly overstates it. If I’ve understood right, they are arguing (with strong evidence) that the simple technique of making neural nets bigger and bigger isn’t quite as magically effective as people say — if you use it on its own. In particular, they evaluate LLMs without two common enhancements, in-context learning and instruction tuning. Both of those involve using a small number of examples of the particular task to improve the model’s performance, and they turn them off because they are not part of what is called “emergence”: “an ability to solve a task which is absent in smaller models, but present in LLMs”.

They show that these restricted LLMs only outperform smaller models (i.e demonstrate emergence) on certain tasks, and then (end of Section 4.1) discuss the nature of those few tasks that showed emergence.

I’d love to hear more from someone more familiar with this stuff. (I’ve done research that touches on ML, but neural nets and especially LLMs aren’t my area at all.) In particular, how compelling is this finding that zero-shot learning (i.e. without in-context learning or instruction tuning) remains hard as model size grows.

@prologic@twtxt.net +1 for FrankenPHP. And built into caddy is also swell.

I love shell scripts because they’re so pragmatic and often allow me to get jobs done really quickly.

But sadly they’re full of pitfalls. Pitfalls everywhere you look.

Today, a coworker – who’s highly skilled, not a newbie by any means – ran into this:

$ bash -c 'set -u; foo=bar; if [[ "$foo" -eq "bar" ]]; then echo it matches; fi'
bash: line 1: bar: unbound variable

Why’s that happening? I know the answer. Do you? 😂

Stuff like that made me stop using shell scripts at work, unless they’re just 4 or 5 lines of absolutely trivial code. It’s now Python instead, even though the code is often much longer and clunkier, but at least people will understand it more easily and not trip over it when they make a tiny change.

Hmmm I’m a little concerned, as I’m seeing quite a few feeds I follow in an error state:

I’m not so concerned with the 15x context deadline exceeded but more concerned with:

And:

Hmmm, maybe the stats are a bit off? 🤔

I’ve seen that nick=lovetocode999 a bunch.

@prologic@twtxt.net I’m still getting this crap:

Something like 100 Gbytes of this junk has accumulated since I updated and re-started the server. I’m now running the latest version of yarnd, so the update did not fix the problem. Something else is going wrong.

How are temporary files growing to 10 Gbytes in size? The name of the file is “yarn-avatar”, but why would avatars be so large?

@prologic@twtxt.net Alright, running yarnd 0.15.1 now. I stopped my hack so we’ll see if the VPS gets clogged with junk 😆

after the warm-up the humidity hit me and i realized i was drenched and i could not stop sweating. it was going to be rough, and it was. kept a pretty steady pace which was great… and around 0.70 miles i upchucked in my mouth a bit, which was oh so great, so i eased off the gas towards the end. overall very happy with the effort since normally i do this in the cooler and drier conditions. in addition i have not been doing much speed work so this is great.

As I was writing my latest post on conscious consumption (https://www.davebucklin.com/play/2024/06/27/consumption.html), I learned of Dr. Bronner’s 5-to-1 cap on executive compensation (https://www.drbronner.com/pages/about).

Can anyone recommend and/or vouch for a Chrome/browser extension that lets me write rewrite rules for arbitrary links on a page? e.g: s/(www\.)?youtube.com\/watch?v=([^?]+)/tubeproxy.mills.io/play/\1 for example? 🤔

Unfortunately not on that front. Still the same 404 posting errors and oddly occasional login errors.

That’s why I was wondering if using Go 1.22.4 could be an issue. I don’t know how exactly. Only way to test is to rebuild it with an older version I guess, which is why I did the make clean in the first place. Old habits die hard lol.
