Hello, time for ! :)

I'm a networking geek and researcher living in Berlin, currently working on a PhD in Computer Science. On a technical level, I like access networks such as WiFi and mobile networks, I like measurement and understanding performance, and I do low-level user-space programming in C. I sometimes talk about science, free software, and tech communities, among other things.

@NerdResa I think IPv4 addrs are also scary for people who are not used to them. So I can understand the argument from someone who doesn't know anything about IPv6 yet, especially the inherent structure of the addresses, but I think they'll lose their fear when working with them.

And hey, with hex numbers you can spell funny words much better, which makes for good mnemonics sometimes. For example, I once lived in a student dorm which was assigned the sub-prefix 2001:...:affe 🐒 :)

And yes, we discussed some design decisions in , too, and whether it's good or bad design in general.
But I think that here, the human side is at least as relevant as the technical side.

One student said that addresses looked "scary". They're so long and look so complex, and they're hexadecimal which is unfamiliar to many people.

Also, if a long address is hard to write down, this might make people feel like they're less in control of their network.

I think my students had some really good points and I'm proud of them. :3

Another part of the deployment problem relates to .

Courses can be really slow to adapt.
Students told me in other classes they still learn about classful IPv4. I had to mark that one as deprecated in our basic networking course slides last semester.

I guess this has also to do with teaching not being appreciated enough in some places, not getting enough resources, etc.

Me and the students had some good discussions on why deployment is so slow and why it's so hard.

I think part of the problem is limited resources for deploying things you can't sell as a "new service".
And why change anything about your setup if it's working fine for you? See also: My uni saying they've got enough IPv4 (which is true!) so they don't need IPv6. I tooted about this before.

Today, for my , I did a tutorial that focused on addressing, DHCPv6, and Stateless Address Autoconfiguration.

It was a lot of content and felt rather complex, but it was also a lot of fun.

"Enough about Legacy IP. The rest of this tutorial is about IPv6, the current generation of the Internet." :D

For one thing, I really dislike the notion that "small share of traffic" means it's not important. Somebody (not the speaker) even suggested that this small share might go away or no longer be needed because everything will be Internet giants anyway. Ugh. Such dystopia, but he said it like it was nothing. Makes me sad.

Today I saw a presentation about how a lot of Internet traffic is going via private links these days, such as private peerings by those giant corporations. Apparently the ratio between traffic on public/private links is often like 10%/90%.
The last slide of the talk simply said "The public Internet…" on an otherwise blank slide.
I really didn't like that. Like… don't give up so easily?

Is there space on your homestead for one without youth and vigor
Is there room in your syndicate for the one who rocks and shouts
Does your committee have time for the one who stutters and struggles
Do these tiny homes come with ramps and aides
Will this new utopia hold space for us
Where do the elders sit
Where do the strange ones live
Where is the quiet place
Where we can go to mourn ourselves and others lost

Here's a #question for you fedizens interested in #decentralisation and media distribution: is there a solution to do a #livestream (of audio or video) in a decentralised way, kind of like #Webtorrent but to broadcast, say, a #DJ mix or #radio show? Everyone who is listening is also a relay for the data. I can see that as something really empowering for people who want to #broadcast in a scalable way but are limited by their bandwidth and the gamble of renting a server. (boost appreciated)

Even though #veganism is an ethical position, the advantages for the #environment are compelling.
I first became #vegan because of the #environmental aspects and only after that I got to know the ethical reasons in detail.

OK, this is a "boosts needed" post, please boost this if you see it. At least one organisation I'm involved in has a major problem in that it runs online and needs to be able to ballot members, and just about all the easy services for doing so aren't GDPR compliant.

Would anyone be interested in clubbing together to try and run a Euro-side, compliant server of CIVS or a similar e-voting system that could be used by community groups, activist orgs, and so on?

♲ ⚠️ Heads-up: the #EU is considering ways to regulate software that runs on radio-enabled devices due concerns about interferences.
Some of their solutions could significantly harm #postmarketOS, but also related project such as #UBports, #LineageOS and #Replicant (among others).

The initiative is now seeking feedback, don't hesitate to send them yours! It seems that Non-eu citizens can contribute as well. There's not much time left, so act quickly!…

#ICANN is proposing allowing unlimited fee increases for .org domain names, which currently are allowed to increase a maximum of 10% annually at

Until April 29 you can send a comment to express your disagreement.

If you wonder why this is relevant, consider that many non-profit organizations around the world might be forced to change their domain by simply raising the price enough.

Don't forget that in some places people strive to gain 10$ in a month.

I love this video on why some Asian people swap r's and l's in English.

Some takeaways:

* They don't do it like in racist American movies

* English l and r are really weird sounds that can be hard to make and hear. We just don't notice that because we're used to them

* Native English speakers are at least as bad at hearing tones in languages like Chinese that use them. Tones sound the same to us for the same reasons r and l sound the same to others
