  • I’m rarely ever going below 21 kmh average (!) on my 16km commute. Of course I am going slow where it’s necessary and dangerous and try to be as responsible as possible. Nobody wants to get hurt. But using 20 km/h speed limits beyond local hot spots would be very unrealistic given a road bike easily reaches 40+ kmh on flat terrain without a mandatory speed gauge. And the latter is also a crucial obstacle. How should speed limits be enforced when people are not forced to mow their speed? And if they are not, what’s a number on a sign worth? I am guessing not much.


  • I don’t think you are paranoid. This technology is creepy as hell. Almost all cars are connected nowadays and send data back to the manufacturer’s server—visible or not. In the best case it’s just the service history, in the worst case live positions and more. Some cars stop working if the server is shut down *cough. Cameras equipped to unlock based on a face record biometric data. And honestly, would you trust your car manufacturer (!) to handle your biometric data?






  • I’m not convinced that answering division with exclusion rather than dialog is a good idea. Claiming the artist promotes a genocide by the Israeli government not disagreeing with him is very steep. That supposed abuse of the tournament through propaganda needs more evidence in my eyes. And I wanna add: I don’t disagree that there have been genocidal statements coming from the Israeli government and other bodies involved in the conflict.


  • I’m so tired of this. The idea is to unite in music and not to unite through not seeing someone there. Did Israel, the USA, the Hamas, etc. commit war crimes? Most likely (leaving it to the courts to rule that). And what do we gain by excluding Israeli artist from a music competition? Nothing but moving back into the comfort zone. The artist wouldn’t even be given a chance to criticize the own government.


  • From an environmental physics point of view, this is not very weird: Warm air holds more absolute amount of water, leading to stronger downpours and longer dry periods. One could also say, the world is getting warmer and this a little “more like summer”. And strong rains converts to strong surface runoff. In other words: Strong rains causes your streets and fields to flood and that water raises the rivers rather than the soil’s moisture. And there we go: The soil is getting drier although there’s more total rainfall.


  • To be fair though, moving personal to institutional knowledge was always a challenge and rarely works really well. While I value apprenticeship a lot (I do science in Central Europe where that is pivotal) I wonder whether it is also a way to move personal knowledge from person to person without ever becoming institutional knowledge. Management didn’t just bury the legacy of Ben, they missed making sure that Ben and Sarah were leaving a manual which cannot burn. We know similar problems because we, as in the scientific endeavour, keep telling people that doing core developments and writing papers about it on half-year contracts in different institutions half a globe apart for a decade is about excellence and learning to become senior rather than a lack of commitment. And we have done so for a long time. But at least juniors, dreaming of becoming a sailor on the research vessel, keep coming.

    And after watching ML is exacerbating existing problems in other fields for some years, we start (!) debating whether it might be slowly replacing us, too. But rather than challenging LLMs writing papers so that other LLMs can summarize them for us, we are still thinking about the next paper and how it will be cited most because that is how it always was and will always be.

    So it is not just about greed. It is the idea of ever performing better to death and the way we define success. The same reason we self-optimize and love that fitness watch and the paid subscription so much because it helps us building habits and being strong and fit and better rested so that we can work even better. In the end, we must acknowledge that we have been part of it all along and the rest is a mirror of what societies’ rules have become.


  • I don’t find this convincing. Everyone knows how easy it is to click “yes” without actually knowing what’s behind it even reading it at all. There’s a reason that “I have read the terms and conditions” is the most common lie on the web. Also, no one will read a lot of information. So adding AI sounds great, doesn’t it? While this is a technical opt-in, it is still really close to an opt-out.

    And then the ML generated code. I am aware it’s anecdotal evidence and might not mean anything but every time I tried Ubuntu, I deleted it after a few days because I found the bugs way too annoying after hitting too many road blocks. So if a buggy prone desktop environment additionally accepts ML code, it makes me suspicious and wanna stay away from it.




  • Not a legal argument but what is the possibility of modifying and redistributing the software worth of the entire branding (!), etc. have to be kept intact. Doesn’t that impose limits on modifications in the first place? Doesn’t feel much like the idea of a viral copyleft license. Also, if the first thing after a prominent fork is starting a legal fight over subtleties in the license with the goal of preserving one’s brand, I’m not so sure why the software was distributed with an AGPL in the first place. The whole thing doesn’t seem to add up.


  • I was always wondering the same and found the related choices always somewhat inconsistent. My own anecdotal experience was that Ubuntu was always to buggy to actually use it in production (every time I tried, I ended up removing it after a few days only due to driver road blocks and os-related bugs). Moreover, using Debian, as many said before, is a question of feature stability and extensive testing. That’s great for server deployment but not so great for consumer electronics. Thus trying to base a distro on Debian while trying to fulfill the expectation of receiving recent developments in the software seems counterintuitive to me.

    Disclaimer: I’ve made a lot of very good experiences with Arch and derived distros and use them in production for more than a decade. Given my not so good experience with Ubuntu I’m certainty on the biased side here.
