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.

I'm still figuring out how to stay in touch with all those people who are now 8 or 9 timezones away.

But I kind of also want to meet new people who are in the same timezone... (Pacific)

How is that supposed to work? I have no idea, but I guess it's worth trying... something.

I moved to the US and started my new job almost two weeks ago.

Interesting times to be in a place where I barely know anybody, for sure.

Also worth mentioning:

“If you are part of a group that is under-represented in Free and Open Source Software communities, we particularly encourage you to apply. We acknowledge that our project and team are not as diverse as we would like them to be. We understand that we're part of the problem. We want to be part of the solution.”

“Feel free to not include your legal name, gender, or photo in your CV.”

The Tails team is looking for a “Privacy loving Linux generalist”:

Emphasis on the last two items in the list of requierements:
“• Have guts feelings or ethical reasons to be interested in online privacy.

• Like to learn new stuff: Tails is big and you probably don't know everything yet — nobody does!”

If you feel like applying, do it now!

covid-19, working class, organizing

Many of you already do it but we want to ask and urge everyone on and of course on other instances to add a CW (corona or covid19) to *all* toots in a relation with the corona virus pandemic. Additionally adding the #covid19 hashtag is also a good idea to filter the toots.

The topic is important but there are a lot of people that are for example in a risk group and really don't want to hear every bad joke or every new headline. Help them and be a nice citizen of this instance.

If people want an open network, stop shit-talking open things

The #OpenSalary hashtag now has community unanimity (2 persons 😄)! Use it to share your work conditions, compensation and what you’re up to as a tech or non-tech worker.

Two examples to start:

Thanks to @duponin and @viv.

I'm currently making a list of events I want to attend this year, and was wondering whether there's a standard for writing date ranges. Turns out there is! Thread on some other weird things I found while reading the Wikipedia article:

"Every platform dies off some day. Geocities, LiveJournal, now Yahoo Groups. One day, Medium, Twitter, and even hosting services like GitHub Pages will be plundered then discarded when they can no longer grow or cannot find a working business model"

If you want to try my mini CTF, it's here:

Note that it's just 3 introductory crypto challenges. Not supposed to be too difficult. Aiming to be finishable in an hour or two. It's for my infosec students who are new and have never done a CTF before.

If you play let me know.

Git is planning to switch to SHA-256 soon. This is all great news, but the best thing is the command to convert an existing repo to the new hash. It reads like a shitpost and gets better with each argument:

git convert-repo --to-hash=sha-256 --frobnicate-blobs --climb-subtrees --liability-waiver=none --use-shovels --carbon-offsets

Decentralized SMTP is for the greater good

- SMTP is the way computers exchange e-mails

- it is a decentralized protocol meaning that ANYONE can run a node and be independent

- it is being centralized at companies that have a history of abuse

- it is being centralized in a country that has a history of abuse

I just created a new personal Web page for myself (not online yet), and I'm pleasantly surprised how easy it was.

I used the Huge static Website generator ( and it was mostly quite easy to learn for me.
Such a relief: I won't have to learn JavaScript. :D

In general, I feel guilty for throwing stuff away because what if somebody could still need them?
Also, I feel like it's not sustainable and I should rather repair everything. But I just don't have the time and energy to do it and I usually don't even enjoy taking things apart. :/

Also, I'm wondering what to do with old books and especially magazines.
I can't bring myself to just throw them away, so I'm trying to find somebody who wants them.

But seriously, aren't magazines weird?
They're sent to my house continuously, I might or might not read them (I rarely do), and then they just sit there and keep accumulating dust. :/

Because I'll be moving far away soon, I looked through all my stuff to figure out what to keep, what to give away, and what to throw away.
I found this quite difficult, as I've never been good at throwing stuff away.
Like, I still have my old laptops, some of which are still half working... Still figuring out who to give these to.
