Hey @doguabaris.bsky.social I've implemented your AI Content Disclosure Header proposal into my blog posts. wdyt? sequr.be/blog/2026/09...

Adding AI attribution to my blog articles
As the use of AI to touch up blog articles is now commonplace, I’ve decided to add AI attibution on articles where I used it.

Acknowledging AI will be used to rewrite, inspire, or completely generate blog posts, I got some inspiration from this AI Content Disclosure Header draft (www.ietf.org/archive/id/d...) and wrote a partial for gohugo.io so you can declare your AI usage #hugo #gohugo gist.github.com/TheGroundZer...

Ideetje voor de media: Mochten jullie eens stoppen met elke scheet van Trump wereldnieuws te maken, waardoor hij continu in de spotlight loopt? Áls je dan toch iets over Trump wilt delen, doe het dan over de zaken die zijn bende net probeert te begraven via deze afleidingen?

Q: Is hitting power plants is a war crime? TRUMP: I'm not worried about it. You know what's a war crime? Allowing a sick country w/demented leaders to have a nuclear weapon. If I allowed that to happen like 7 other presidents- many of them say off the record they should've done this a long time ago

By me: Microsoft has fixed three zero-day bugs in Windows and Office that are being actively abused by hackers to break into people's computers. Microsoft said three of the exploits are now public. Google, which helped find the bugs, said one of them is under “widespread, active exploitation."

What's the statute of limitations on e.g. the (alleged?) killing of Green? A criminal case today would allow the Trump admin to push for a not-guilty verdict, making future cases impossible. Perhaps post-Trump a more fair review can be done?

This is fucking grim. Somebody invented a white guy, an "IT professional" named Edward Crabtree, who stopped the Bondi shooting and spread it all over the internet, which was picked up by AI agents and slop aggregation sites. The real hero is a fruit stand owner named Ahmed el Ahmed.

'Hero' who wrestled gun from Bondi shooter named as Ahmed al Ahmed

A "hero" bystander who was filmed wrestling a gun from one of the Bondi Beach attackers has been named as 43-year-old Ahmed al Ahmed.

Video verified by the BBC showed Mr Ahmed run at the gunman and seize his weapon, before turning the gun round on him, forcing his retreat.

Mr Ahmed, a fruit shop owner and father of two, remains in hospital, where he has undergone surgery for bullet wounds to his arm and hand, his family told 7News Australia.

The US wants to analyze your social media accounts/posts for the last 5 years. Time to set up a fake account and feed it "neutral" content so it can build a 5y backstory. Claiming you have no social media account is sus, sharing an @ that's only a week old as well. But one with 5 years of cat pics?!

Weet iemand of de NMBS ook dit principe hanteert? Treinen aan 80% van de maximumsnelheid laten rijden zodat je die 20% buffer kunt gebruiken om vertragingen in te halen. Zo verhoog je de betrouwbaarheid van de timing voor een kleine kost in reistijd. toot.yosh.is/@yosh/115636...
I didn't realize that Swiss trains apparently also adhere to the "schedule for 80% of capacity rule".

Apparently trains in Switzerland go around 80% of the top speed possible on the track. The 20% overhead is used to make up time in the case of delays.

The thinking is: stable and predictable operation is more important than going faster. Because the cost of passengers regularly missing layovers is much higher than the benefits of trains being 20% faster.

Robin Williams’ daughter Zelda hits out at AI-generated videos of her dead father: ‘Stop doing this to him’
Film-maker tells the public to stop sending her videos, saying: ‘You’re not making art, you’re making disgusting, over-processed hotdogs out of the lives of human beings’ Zelda Williams, the daughter of the late actor and comedian Robin Williams, has spoken out against AI-generated content featuring her father. “Please, just stop sending me AI videos of Dad,” Zelda wrote in an Instagram story on Monday. “Stop believing I wanna see it or that I’ll understand, I don’t and I won’t. If you’re just trying to troll me, I’ve seen way worse, I’ll restrict and move on. But please, if you’ve got any decency, just stop doing this to him and to me, to everyone even, full stop. It’s dumb, it’s a waste of time and energy, and believe me, it’s NOT what he’d want. Continue reading...

Volgens politici is #ChatControl noodzakelijk omdat men in de strijd tegen kindermisbruik tegengewerkt wordt door geëncrypteerde chatkanalen. Als een groep journalisten dit kan, zonder toegang tot de tools waar politiediensten toegang tot hebben, bewijst dit nog maar eens dat dat een overdrijving is

I'm not fully up-to-speed yet on #IPv6 but this is one of the reasons I can think of to hold off on residential IPv6 usage. Yes there are privacy mechanisms to prevent direct mapping of an IP to a device, but you can still track metadata of individual devices. It doesn't get bunched up together.

Just a friendly reminder to any followers from the UK. This is what your ISP sees in the network traffic of a fictional household. Be wary that using a VPN makes you stand out from the crowd. And metadata can still tell a lot about you.
- 00:00-06:00 barely any network traffic
- 06:00-09:00 mostly HTTP(S) traffic to social media sites and news sites
- 09:00-17:00 drop in network traffic
- 17:00-22:00 mostly HTTP(S) traffic to social media, YouTube, streaming, some more random sites
- 22:00-22:15 VPN traffic, unreadable destinations, streaming-like bandwidth usage
- 22:15-00:00 mostly HTTP(S) traffic to social media but dropping network usage
