IBM unveils the LinuxONE Emperor 5
Following the recent release of the IBM z17 mainframe, IBM today unveiled the LinuxONE Emperor 5, which packs much of the same hardware as the z17, but focused on Linux use. Today we’re announcing IBM LinuxONE 5, performant Linux computing platform for data, applications and your trusted AI, powered by the IBM Telum II processor with built-in AI acceleration. This launch comes at a pivotal time, as technology leaders focus on three critical imperatives: enabling … ⌘ Read more

* 101f3eb0 - (HEAD -> main) Fix a bunch of UX to do with following/unfollowing, bookmarking and unbookmarking (3 seconds ago) <James Mills>

Testing UI/UX is hard™ 😉

Today, I did my longest bike tour this year so far. I went north to a lake in a neighboring district, mostly following the Weser-Harz-Heide route, which I already partly followed on my journey from Kassel to Braunschweig last year. There I sat down on a bench for half an hour and then returned. I had plenty of headwinds on the way there and a bit of tailwind on the way back, although the wind was mostly from the side. This time, I luckily did not mess up the OsmAnd tracking. Despite the wind, it was a lot of fun! ⌘ Read more

How to Enable Automatic Dark / Light Mode on iPhone & iPad
If you’re an iPhone or iPad user, you might appreciate a feature that automatically switches your devices appearance from Light Mode to Dark Mode, and vice versa, automatically. Furthermore, you can set the automatic enabling of Dark and Light mode to follow sunset and sunrise, or a custom schedule, whichever you prefer. As you probably … [Read More](https://osxdaily.com/2025/05/02/how-to-enable-automatic-dark-light … ⌘ Read more

Confession:

I’ve never found microblogging like twtxt or the Fediverse or any other “modern” social media to be truly fulfilling/satisfying.

The reason is that it is focused so much on people. You follow this or that person, everybody spends time making a nice profile page, the posts are all very “ego-centric”. Seriously, it feels like everybody is on an ego-trip all the time (this is much worse on the Fediverse, not so much here on twtxt).

I miss the days of topic-based forums/groups. A Linux forum here, a forum about programming there, another one about a certain game. Stuff like that. That was really great – and it didn’t even suffer from the need to federate.

Sadly, most of these forums are dead now. Especially the nerds spend a lot of time on the Fediverse now and have abandoned forums almost completely.

On Mastodon, you can follow hashtags, which somewhat emulates a topic-based experience. But it’s not that great and the protocol isn’t meant to be used that way (just read the snac2 docs on this issue). And the concept of “likes” has eliminated lots of the actual user interaction. ☹️

@movq@www.uninformativ.de If we’re focusing on solving the “missing roots” problems. I would start to think about “client recommendations”. The first recommendation would be:

1. Replying to a Twt that has no initial Subject must itself have a Subject of the form (hash; url).
   

This way it’s a hint to fetching clients that follow B, but not A (in the case of no mentions) that the Subject/Root might (very likely) is in the feed url.

If we must stick to hashes for threading, can we maybe make it mandatory to always include a reference to the original twt URL when writing replies?

Instead of

(<a href="https://we.loveprivacy.club/search?q=%23123467">#123467</a>) hello foo bar

you would have

(<a href="https://we.loveprivacy.club/search?q=%23123467">#123467</a> http://foo.com/tw.txt) hello foo bar

or maybe even:

(<a href="https://we.loveprivacy.club/search?q=%23123467">#123467</a> 2025-04-30T12:30:31Z http://foo.com/tw.txt) hello foo bar

This would greatly help in reconstructing broken threads, since hashes are obviously unfortunately one-way tickets. The URL/timestamp would not be used for threading, just for discovery of feeds that you don’t already follow.

I don’t insist on including the timestamp, but having some idea which feed we’re talking about would help a lot.

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 🤣

@kat@yarn.girlonthemoon.xyz saving you a bookmark:

The following flags no longer exist:

--max-cache-items

Instead use --max-age-days, which controls how much of the cache is pulled back for Timeline, Discover and Mentions views.

@prologic@twtxt.net Since you have to check and double check everything it spits out (without providing sources), I don’t find any of this helpful. It’s like someone’s in the room with you and that person is saying random stuff that might or might not be correct. At best, it might spark some new idea in your head and then you follow that idea the traditional way.

Information published on the internet (or anywhere, for that matter) was never guaranteed to be correct. But at least you had a “frame of reference”: “Ah, I read this information about Linux on a blog that usually posts about Windows, so this one single Linux post might not necessarily be correct.” That is completely lost with LLMs. It’s literally all mushed together. 🤷
