Linus Torvalds’ AI Code Improved: Huge Performance Wins With Reworked Code
Last week I wrote about Linus Torvalds leveraging AI to come up with a hefty Linux kernel improvement using Claude Code. The code is for reading from the page cache without folio references to help workloads of small reads from a single file across many CPU threads. Meta engineer Kiryl Shutsemau has taken that code and reworked it and showing extremely promising performance results… ⌘ Read more

Google Is Silently Linking Your Phone Number Across All Signed-In Accounts

@david@daiwei.me It’s the right thread, yeah, and not a jenny thing per se. I used the Vim username completion and didn’t pay attention. 😅

NVIDIA Vera SMT Performance Benchmarks
Recently I was provided remote access to a NVIDIA Vera server with the dual socket Vera CPU Superchip providing 176 Olympus cores plus with NVIDIA’s Spatial Multithreading “SMT” implementation providing 352 total threads. With this benchmarking was free rein for testing, including CPU power and frequency monitoring. Over the next few weeks will be a number of articles looking at different areas of NVIDIA Vera performance. One of the areas I was most eager to test was looking at Ver … ⌘ Read more

Intel Granite Rapids WS vs. AMD Threadripper Zen 5 SMT Performance

Linux 7.4 Could End Up Seeing Kernel Builds ~36% Faster, Incremental Builds ~70% Faster
Earlier this month I wrote about a patch series posted to the Linux kernel mailing list that addressed a lot of “hideous code” to make Linux kernel builds faster. A number of single-threaded bottlenecks were tracked down and fixed within the Linux kernel thanks to the assistance of AI. A second revision of those patches hit the mailing list this morning and there is hope they could be upstreamed for Linux 7.4… ⌘ Read more

@Sumomo@sumomo.neocities.org What client are you using btw? 🤔 Does it support threads, and other v2 specs? 🤔

If I say companies should at least consider the 3 line CC license before scraping my sites, I’m seen as the unreasonable one.

But when I use an alternative forontend, to read feeds on their sites, without having to make yet another free account, now the same companies and their users scream about some unspecified part of their license being violated, threaten legal action and expect me to care about it.

Intel Granite Rapids WS Core Scaling Performance With The Xeon 678X
Last week I provided a look at the Intel Xeon 600 series Hyper Threading performance with the Xeon 678X “Granite Rapids WS” processor for HT/SMT on and off. That was interesting while another reader request was to look at the CPU core scaling performance for this high-end workstation processor.

Real tired of doing these, but here’s another Android developers vs Google update, this time there’s both good and bad news.

The good:
-Users will be able to enable “sideloading” for all current and future devices, attached to their Google account, rather than having to undergo the tedious 24 hour wait including process, on each device.

-Rather than these changes to “sideloading” and “advanced workflows” being implemented at random different dates, in different countries, we’ll all get them come 2027.

The bad:
As GrapheneOS developers recently mentioned “Google replaced pushing Git tags for certain source code with obtaining source code via Google Drive after making a request through Google Forms. It’s completely ridiculous and they’ve gradually become very slow at handling requests. They’re in clear violation of the GPLv2 now.”

@arg@twtpub.com You actually can, but we highly discourage it and I haven’t really built “Edit” / “Delete” functionality in the Twtxt App that I know you’re using 😅 Twtxt being purely decentralised, meaning that there are absolutely zero decentralised, with the exception of the twtpub.com service you’re using to reduce as much friction as possible for newcomers to try things, makes supporting threads a bit of a controversial topic 😆 – In the end we are sticking with the Hash v2 extension, making threads use content addressing, so even if you did delete/edit a Twt, you have to be carefuly it hasn’t already been replied to in the ecosystem 🤣

but yes, however you cannot currently add it or delete post via the app as I haven’t really built that feature at the moment you technically can do it, but you do run into some challenges with breaking threads if you’ve already published something and then go back and edit it so we generally advise not to do that too much if you can help it

Posting the review and plan here for posterity as it is related to this thread: https://canvas.mills.io/a/6QVGjzRW

The PR(s) as-is will likely not go ahead I’m afraid. More work to be done, but this is basically all about the “Recovery” story and how to anchor and notion of an “account” without well umm an account 🤣

sue expand ed on the main thread

@prologic@twtxt.net No. After the cutoff-date, hashes are expected to be v2. End of story.

(In jenny, a twt can only ever have one thing that can be used for threading.)

Does yarnd still support the old “threading”? Let’s see.

@movq@www.uninformativ.de ha ha in this case I think I’m OK with a broken thread ha ha

@david@daiwei.me This is another dangling thread:

Trying to fetch "#kyjhiwcxeknm" from Yarn pod https://twtxt.net ...

@lyse@lyse.isobeef.org True. Although I _think) this isn’t a problem and this thread is m00t 😅

Good morning. I’m seeing so many broken threads. You’re still investigating this, right?

Yeah to @david@daiwei.me’s point re Editing. It’s only really safe to do so if you are sure that no-one has yet fetched your feed or replied to your Twt. But even then, you have to be quick 🤣 Editing/fixing a Twt inside of an existing thread is “oaky”, as long as it also doesn’t get forked and becomes the root of a new conversation 😅

@movq@www.uninformativ.de this one:

2026-07-11T17:28:31Z	() No yet. Let’s keep it rolling a little bit longer. I am reply to “[..] I don’t see any broken threads here. 🤔“. I can’t tag followings while on mobile. <-- THIS BROKE

Was a reply to:

2026-07-11T16:39:22+00:00	(#iqqsqst5vokf) @<david https://daiwei.me/twtxt.txt> Well, I don’t see any broken threads here. 🤔

@david@daiwei.me Well, I don’t see any broken threads here. 🤔

@bender@twtxt.net No idea. I can only tell you that the correct hash would have been rwzz277nkyju for this line:

@bender@twtxt.net Ah, the first twts were from https://raw.githubusercontent.com/Fastidious/fastidious.github.com/master/twtxt.txt, not https://daiwei.me/twtxt.txt. Fetching the GitHub feed completes the thread. 👍

@david@daiwei.me (This thread is broken again on my end. Another bug or fix not released yet? 😅)

As an example, this is a thread @GabesArcade@gabesarcade.com’s Arcade@gabesarcade.com and @david@daiwei.me carried all on twtxt.app, no issues: https://twtxt.net/conv/r4uf52ggwseh

@movq@www.uninformativ.de I figure there is a bug somewhere, but where?

@kiwu@twtxt.net Hanging on by a thread is plenty good enough for many spiders, so it should be sufficient for you, too!!1!

Hmmm the Twtxt App isn’t grouping threads correctly 🧐

Adding support for forking, forked conversations and navigating back to the root of a thread for the Twtxt App 🤞

It’s no big deal of course, we are fully aware of the couple of rare(ish) edge cases with the threading model.

@GabesArcade@gabesarcade.com Did you by change edit or otherwise delete the Twt you replied to (2nd last in your feed) with the reply/thread id lleeypvkzbw2? That Twt was never ingested by twtxt.net (and likely the search engine) so umm hmmm threading breaks 🤣

@GabesArcade@gabesarcade.com’s Arcade@gabesarcade.com You will want to either build a client or use one of the ones listed here – Either way you choose! 👌 I just noticed as well in this Twt I’m replying to (threading is a thing™) that you @-mentioned@twtxt.net @bender@twtxt.net incorrectly 😅

@arne@uplegger.eu if you see this reply threaded nicely then yes you did! 😅

How truly wonderful! I went out tonight and the first thing I noticed was the temperature drop. It felt actually quite pleasing. What a welcome surprise, I didn’t expect that at all. It was warmer in the forst than between the fields. The tiniest breeze helped to cool off the surroundings I think. Right now, the temperature shows 23°C. It’s supposed to reach 18°C at 5 in the morning before it rapidly shoots through the sky again.

When I left the house I even saw the very end of a nice sunset. A bat was around, too. The several thousand fireflies delivered a fantastic show. It’s such a pity that I cannot show this to you. :-(

There were many frogs or toads around. Luckily, the light tan gravel road made for a good constrast to the darker hopping amphibians. So, I spotted them just in time. No animals were harmed.

The moon was out and lit up the scenery. I was perfectly chasing my own shadow for several hundred meters on a forest road. I had the moon right in my back. That moon light shadow felt magical. <3

It must have set a new record on picking up spider webs along the way. The threads around arms and legs always feel quite yucky. People were blasting music somewhere in town. You could here that noise in the entire forest. I found that rather annoying. All street lamps are operational again, so I got already blinded right at the entrance to the town. But other than that, this was a very nice evening stroll. Totally recommended. Already looking forward to tomorrow. :-)

Nice work! Threading + mentions is where it gets fun 😅 Ping me if anything in the spec is unclear 👌

@prologic@twtxt.net @bender@twtxt.net Thanks! Yeah, it already supports Twt Hash via twtxt-lib (both v1 and v2, when the time is right), plus most of the other features (multiline, user-agent, and metadata), and I’m working on (re-)implementing threading, mentions, and hash filtering (to make conversations easier to follow).

Here’s a current snapshot of my local version, in case anyone is interested:
