I'm not an Android user, so pardon me if this is a stupid thing to say, but it's weird to me that these phones apparently have some new UI unique to them. I thought Android was just Android. Won't other Android phones get this update?

Android is not just Android. The device vendors have to customize it to fit their devices by including drivers for example. Device vendors have the option to change the look pretty heavily, Samsung TouchWiz was infamous, Chinese vendors also offer very customized versions, including making it look like iOS. What you are seeing is material design 3 "expressive" which will be rolled out in the next minor Android version and Google apps

> This caps capacity and reliability.

Karlsruhe: The local operators have severe quality issues, in part due to this concept. There are like four points in the city where issues impact the whole network. The rolling stock is very bad compared to the other regional trains running in Baden-Württemberg (no/bad ac, flaky internet, no sockets, bad seating). The trains have way too little capacity, I’ve seen incidents, where they run three coaches (which they don’t do often, they are too long to enter the city), where people could not get in anymore. Some of the stations in the surrounding area are absolutely mental (Durmersheim for example), you have to walk over rails where ICEs and cargo goes through. Some trains are split or merged when leaving or entering the city, but it always causes delays. When trains can’t use the heavy metal rails and thus not leave the city due to ICEs getting priority, a lot of inner city traffic can be affected. The cooperation between the different infrastructure operators is also a source of problems.

Do not take Karlsruhe uncritically as an example where this model works well, yeah sure average numbers make it look good, but the reliability is complete ass. KVV always manages to surprise me on how bad it gets.

Just a small hardware project: I am building a cocktail mixer in an old PC case. I saw something similar at a con over Easter and had to build one myself, it had a tap coming out of the 3.5" bay and the ingredients were inside the pc case. It uses peristaltic pumps to move the different ingredients to the cup. It is very simple, but still took a couple of days to complete. In detail it consists of 6 x peristaltic pumps, 3 x L298N motor driver, 3 x PCF8574 io expander and an esp32. The software for the esp32 is very dumb and I actually coded it correctly before I had all the parts, it just enables and sets the speed for the motors and is attached via USB to a laptop. There a webapp is used to manage ingredients and recipes.

> I'm also not yet sure what to think about splitting education and research. It goes against the Humboldtian Ideal, especially in the universitys both topics are connected.

According to the German constitution (Grundgesetz), schools and universities are (mainly) the responsibility of the individual German states, not the federal government.[1] (A hybrid is the Karlsruhe Institute of Technology that has a university branch under the supervision of the state of Baden-Württemberg and a research centre branch under federal supervision.) The educational tasks of the federal government therefore basically relate to extracurricular and non-university education, such as early childhood education or adult further education.

At the level of the individual states, higher education and research are generally combined in one ministry and school education in another.

[1] Actually the Grundgesetz states in Art. 30: "The exercise of state powers and the performance of state duties shall be a matter for the individual states (Länder), unless otherwise provided for or permitted by this Basic Law." The authority of the federal government in education policy is therefore derived from what is explicitly mentioned in various places in the Basic Law. A short overview what that involves can be found here: https://www.bundestag.de/resource/blob/416682/db04b405a48dbe... (PDF, 2009, in German).

Thank you for the background explanation and the link. KIT is actually my Alma Mater (cs). You are right the overlap is not that large. I was thinking about the WissZeitVG, Exzellenzstrategie, Tenure-Track-Program. As for the Länder, I personally think the transition between the Abitur and university could benefit from stronger collaboration between the involved ministries. For example by better aligning the educational goals of high school to the demands of universities and by integrating education research into schools. By this I mean the continuous application of the results of educational research to schools and the constant monitoring of schools.

I agree that merging the technology division from the ministry of economic affairs (BMWK) to the new research ministry is a good step as both ministries have been large providers of funding. The BMBF funds DFG, as well as the large science organizations in Germany (Fhg, Mpg, ...), the BMWK has funded research which is closer to applications, of course looking to enable economic activity. I'm unsure why the ministry gets a special focus on aerospace, this topic is being worked on by the DLR, funded by BMBF. I'm also not yet sure what to think about splitting education and research. It goes against the Humboldtian Ideal, especially in the universitys both topics are connected. On the other hand, it might enable the ministries to be more focused and do reforms that don't depend on each other to be performed more quickly. The research ministry will go to CSU, the bavarian sister party of CDU. While it may not be very popular amongst many Germans, because CSU is seen as conservative and individual CSU politicians are not famous science policymakers, Bavaria is a successful science hub. Munich is home to international leading institutions (TUM, MPG, FhG). Bavaria is also a hub for aerospace with Aibus and MTU and startups like Isar Aerospace and Rocket Factory Augsburg. Maybe repeating what bavarian policymakers have done regionally to the whole of Germany will be good.

L4 was popular at my university (Karlsruhe). While I never really looked into it in any detail, it always appeared to me like a project that is primarily interested in testing some theoretical ideas, but not in building anything that would be practically useful.

That was 20 years ago. As far as I can tell, this has not changed. (Quick googling tells me there appear to be some efforts to build an OS on it, but they all look more like proof of concepts, not like something with real-world use.)

Jochen Liedtke became a professor in 1999 in Karlsruhe, sadly he passed away only shortly after in 2001. I don't know if his successor Bellosa still does research on L4. There was the L4Ka project which appears to be completed. In the bachelor lecture on OS by him it's not part of the curriculum.

Rittinghaus, alumni of Bellosa, is involved with Unikraft [0], which was featured a couple of times on hn, and is using unikernel technology.

Serious question: how is DoH supposed to help when the resolver itself is being asked to return bad results? DoH makes sense if something is MITM-ing your DNS requests, but it sounds in this case that Google is being asked to just straight-up return bad results?

xxmarkuski · 5 months ago

DNSSEC is the actual solution, providing authenticity and integrity for DNS records. The DNS client can verify that the received DNS response is what the zone admin intended. Additional records (NSEC / NSEC3) are used to provide a proof of non-existence, preventing suppression from a mitm attacker. But if your government is mitming you, you don't want them to see you use DNSSEC. DoH is useful in that case, because a mitm sees only https traffic, which is less suspicious than DoT.
