In-reply-to » Something odd just happened to my twtxt timeline... A bunch of twts dissapered, others were marked to be deleted in mutt. so I nuked my whole twtxt Maildir and deleted my ~/.cache/jenny in order to start with a fresh Pull. I pulled feed as usual. Now like HALF the twts aren't there 😂 even my my last replay. WTF IS GOING ON? 🤣🤣🤣

@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 :-)

In-reply-to » @movq Is there a good way to get jenny to do a one-off fetch of a feed, for when you want to fill in missing parts of a thread? I just added @slashdot to my private follow file just because @prologic keeps responding to the feed :-P and I want to know what he's commenting on even though I don't want to see every new slashdot twt.

@prologic@twtxt.net How does yarn.social’s API fix the problem of centralization? I still need to know whose API to use.

Say I see a twt beginning (#hash) and I want to look up the start of the thread. Is the idea that if that twt is hosted by a a yarn.social pod, it is likely to know the thread start, so I should query that particular pod for the hash? But what if no yarn.social pods are involved?

The community seems small enough that a registry server should be able to keep up, and I can have a couple of others as backups. Or I could crawl the list of feeds followed by whoever emitted the twt that prompted my query.

I have successfully used registry servers a little bit, e.g. to find a feed that mentioned a tag I was interested in. Was even thinking of making my own, if I get bored of my too many other projects :-)

Gaining kernel code execution on an MTE-enabled Pixel 8
In this post, I’ll look at CVE-2023-6241, a vulnerability in the Arm Mali GPU that allows a malicious app to gain arbitrary kernel code execution and root on an Android phone. I’ll show how this vulnerability can be exploited even when Memory Tagging Extension (MTE), a powerful mitigation, is enabled on the device.

More basement:

I completely forgot that DVD-RAM was a thing once. Found my old disks and they still work. 🤯 The data on them is from 2008, so they’re not that old. Still impressive.

The disks are two-sided. On the photo, that particular side of the disk on the left appears to be completely unused. 🤔

And then I read on Wikipedia that DVD-RAMs aren’t produced anymore at all today. Huh.

(I refuse to tag this as “retrocomputing”. Read/write DVDs that you can use just like a harddisk, thanks to UDF, are still “new and fancy” in my book. 😂)

In-reply-to » Yeah, the lack of comments makes regular JSON not a good configuration format in my view. Also, putting all keys in quotes and the use of commas is annoying. The big upside is that's in lots of standard libraries.

@lyse@lyse.isobeef.org its a hierarchy key value format. I designed it for the network peering tools i use.. I can grant access to different parts of the tree to other users.. kinda like directory permissions. a basic example of the format is:

@namespace
# multi
# line
# comment
root :value

# example space comment
@namespace.name space-tag 

# attribute comments
attribute attr-tag  :value for attribute

# attribute with multiple 
# lines of values
foo :bar
      :bin
      :baz

repeated :value1
repeated :value2

each @ starts the definition of a namespace kinda like [name] in ini format. It can have comments that show up before. then each attribute is key :value and can have their own # comment lines.
Values can be multi line.. and also repeated..

the namespaces and values can also have little meta data tags added to them.

the service can define webhooks/mqtt topics to be notified when the configs are updated. That way it can deploy the changes out when they are updated.

I had some time to code this afternoon, so I have made some polling now, so if a task is not completed it waits 2 secs and tries again, if the server reports a error in the task it stops polling, when the task is successfull it will add the resulting image tag to the status input field. Quite pleased with this now. After this I’ll work on ‘view conversation’, meanning you can open a conversation and see all posts in it, that’ll make it even easier to follow conversations and to reply etc.

In-reply-to » Posting from c++, fltk GUI.

A lot of more work needs to be done, but at least now I got the basic timeline stuff done, took a good while to figure out how to solve it, but now I know. The reason why the statuses are cut short on some is because of html tags and stuff like that - c++ is a bit picky with strings and stuff like that. but I’ll get that sorted as well.
At least I can show the first screenshot. Keep in mind the GUI is not at all finished, I’m working on the basics first, implement all the features, then I work on finishing touches.

In-reply-to » Posting from c++, fltk GUI.

Okay, so it seems like the label\text I use for statuses does not like the strings from posts.
Especially if they contain html tags and such (which the often do), it just breaks the text.
I wonder what I can do with that.. I kinda want to not have html tags in the json reply.
Have to think a bit about how to solve it. Took a while to figure it out, the text was just garbled.
I created some long example strings with regular letters and such, to see if X number of posts would show up, and they did, but when I then replace my test strings with text from json - it goes all wrong again.

Struct Tags with Underscore Before Function Names
In the Go world, an underscore (_) before an expression is called a blank identifier. As you may already know, identifiers—user-defined program components, e.g., name of a function, variable, or package—in Go must be preceded by an underscore or a letter (a-z or A-Z).
