interesting geek art at hermannplatz u-bahn station. #sarahfriend #geek #network #patch #hermannplatz #berlin

pro tip to the artist: in practice, to tighten the cables it is recommended to use velcro or similar, when you cut zip ties they become razor sharp and i can't remember how many times i have cut my hands when needed to reach something behind the rack.🤓

For those interested in such things, here is a set of scripts to extract and filter data associated with rail from the full OpenStreetMap dataset for the Islands of Northern Europe (Great Britain and Ireland) as a GeoPackage here https://github.com/anisotropi4/magpie/releases/download/v2.0.1/ine-track.gpkg.

It identifies railway features, line speed and electrification scheme based on metadata.

The associated source code and repository is here:

But for the #network admins out there, I'm curious: What's your take on captive portals for guest wireless in this day and age?

Personally, I've seen it cause a large number of end-user complaints a majority of the time it's implemented. I'd also question the legal efficacy, especially when a lot of companies are blindly throwing in a generic/default use agreement. I feel like I haven't seen as many guest networks leaning on captive portal as I used to.

Then again, I've been outside of most "enterprise networking" until last year, so I'd love to hear from folks who have been immersed in that area longer.

Dear #network teachers, students and #hacker friends, I have a #browser based network simulator to enable learning #networking. Please have a look and tell me what do you think. Made for desktop or bigger screens.

https://howcomputer.works/netsim/ Everything is in the browser, and there is documentation.

The goal is to allow kids to start learning while their schools/systems are not big enough to be able to build lab networks. It has a small/minimal #curl implementation too. @bagder

Wondering how and why? With @BoxyBSD@bsd.cafe and @BoxedTux@mastodon.social, I’m already running platforms that provide free VPS instances for educational purposes, learning and testing for years now. I guess, providing real AS and peering services (maybe even sponsoring LIR in cooperation [but this would cost money]) could also be very interesting for several ones, apart from the DN42 network. Happily looking for feedback…

ADVICE NEEDED: I own a 4 bedroom, 2 storey house. It is a 1920's UK build with brick internal walls, with a more modern extension. My router sits downstairs in the living room, and the signal is blocked beyond that room. I have 3x TP-Link AV600 powerline WiFi extenders, but the signal isn't enough to cover the whole house. An outdoor office is being built 10m outside the house. I want to buy a mesh network. What do I need, and can you point to something suitable off the shelf? #askFedi #network

Romanian is one of the Romance languages i haven’t studied that have always been difficult to decipher due to its Cyrillic-esque orthography.

am learning to read it with #Mastodon’s translation feature.

humans #network thru #languages. if you want to grow the #fediverse, you must make it easy to translate what dazzles yet cannot be easily read.

yet another reason to love @Gargron’s vision of what the platform could be and the elegantly forward thinking work of the @MastodonEngineering team.

¡ATENCIÓN! 🚨 El 5 de Julio de 2026 entra en vigencia la actualización de los ToS de Linktree. Esto incluye el uso de IA generativa (Dall-E de OpenAI) con los textos, imágenes y links que el usuario suba a su cuenta. Incluso compartirán toda la info del usuario con otros proveedores externos de IA ⚠️

We have updated our Terms and Conditions and Privacy Notice AI Features on Linktree An overview of Linktree's AI features How AI features work AI features on Linktree generate results (called Output) based on information provided to the system (called Input). Input may include things like: Text prompts you enter e.g. asking questions within our Insight Chats feature. Content you upload or add to your Linktree like images or videos e.g. uploading a profile image and using our Restyle AI feature. Information available on the Linktree platform and from your profile including your links e.g. AI generated link titles or AI generated bios. Links you submit to create your Linktree. Information provided by third-party services e.g. authenticating with Instagram so that we can analyse your social media data and provide you with social analytics. The AI system uses this Input to generate Output, which may include text, images, analytics and profile insights or recommendations depending on the feature. https://linktr.ee/help/en/articles/9269822-ai-features-on-linktree?lid=g3hnv8kr9765

Which AI model does Linktree use and why? What is Linktree doing to keep Linkers, visitors, and creators safe? Linktree uses DALL-E 3, provided by OpenAI, to create brand-new custom avatar or thumbnail images. With Linkers and visitors’ safety as a priority, Linktree performs its own reviews of AI-generated content on the platform to ensure compliance with our Community Standards and ethical AI practices. OpenAI’s commitment to safety and transparency aligns with Linktree’s values and Trust & Safety efforts. For example: OpenAI’s policies explicitly forbid usage that might result in harm to oneself or others, e.g. “to defraud, scam, spam, mislead, bully, harass, defame, discriminate based on protected attributes, sexualize children, or promote violence, hatred or the suffering of others.” OpenAI utilizes safeguards that prevent the generation of “violent, adult, or hateful content.” OpenAI/DALL-E 3 “has mitigations to decline requests that ask for a public figure by name” and is “designed to decline requests that ask for an image in the style of a living artist.” https://linktr.ee/help/en/articles/9269822-ai-features-on-linktree?lid=g3hnv8kr9765

#fedihelp to #IT #sysadmin people:

Do you know where I can find online #training (in self-study mode) for people who might need to learn the fundamentals of IT , #network #networking , #linux #shell , etc?

If it is available in an #open #foss spirit (a bit like #KhanAcademy ), that would be fantastic.

I'd like to give some pointers to people who need basic initial guidance.

Thank you!!!

Cher internet, est-ce que vous avez déjà fait un sous-réseau IPv6 délégué derrière une Freebox ?

Attention, je te parle pas de mettre la Freebox en mode bridge, mais bien de la configuration suivante :

• Le réseau IPv6 A : celui par défaut derrière la Freebox

  • Un ordinateur ordi-1

• Le réseau IPv6 B : celui que l'on délégue à un routeur via un "Next Hop"

  • Un ordinateur ordi-2

Avec cette configuration, voici les faits :

• Depuis ordi-1 :

  • Ping IPv6 vers example.com : OK
  • Ping IPv6 vers ordi-2 : ÉCHEC

• Depuis ordi-2 :

  • Ping IPv6 vers example.com : OK
  • Ping IPv6 vers ordi-1 : ÉCHEC

• Depuis dehors (une machine sur internet) :

  • Ping IPv6 vers example.com : OK
  • Ping IPv6 vers ordi-2 : OK
  • Ping IPv6 vers ordi-1 : OK

Note : la même configuration en IPv4 fonctionne (OK) pour tous les cas cités ci-dessus.

Je n'ai pas trouvé plus d'explication et comme ça j'ai l'impression qu'il s'agit d'un bug de la Freebox qui n'arriverai pas à régler le routage IPv6 correctement quand il faut passer d'un préfix IPv6 qu'elle gère à un autre qu'elle gère aussi. Comme si la règle du "Next Hop" ne fonctionnait que pour les paquets venant de l'extérieur et pas de son LAN (genre 2 tables de routages différentes ?).

Est-ce que quelqu'un qui a fait une configuration identique a aussi remarqué ça ou pas ?

Est-ce que vous avez des retours sur le sujet ?

Finally got around to checking out Little Snitch for Linux. It might be ~20 years since the last time ran it (Leopard! Tiger!).

Worth a look if you haven't checked it out yet.

Web interface is cool, especially for simplified look at what hosts are experiencing.

Not packaged for Solus or Alpine but the static musl binaries linked on the download page work fine.

./littlesnitch --daemon

./littlesnitch <- sends you to the default browser and loads the page on localhost:3031 IF the daemon is running
