  • I love your enthusiasm! But as someone who works in semiconductor development, I feel a bit like it is time to abandon this branch of the technology tree for now again. Maybe I am just disheartened from the PhD stress, but where does it really lead to right now? Following up on Moore’s Law right now just seems to promise higher efficiency and lower electricity demands while actually that is mainly greenwashing attempt IMO (lower resolution technologies are more energy and resurce efficient when considering resource demand during production; high device density leads usually to increase of the number of transistors which are operated parallely, so while the single FET is more efficient in dynamic operation, the whole chip might have much higher leakage). At the same time this efficiency is used as justification to just increase the calculation load whithout considering if it is useful (e.g. LLMs). Resources might be better allocated for More than Moore/architectural approaches e.g. for neuromorphic computing to actually reduce the immense AI computing load coming up.

    Sorry for the rant, I think I gotta quit my job.




  • Although usually I am all for adressing your own impact as well and not only blaming big corporations (they are mostly at fault, but they won’t change a thing as long as they can still blame consumers), I think it is important to aknowledge here how dependent individuals can be on cars. No one can single-handedly revolutionize the public transport and some areas, especially in more rural regions, really need forms of individual transport at present. EVs are not solving the big issues, but in regards to carbon impact you can compensate for their production quite quickly with the CO2 you save in comparison to an ICE car (depending on your local energy mix of course). Burning fuel will never be carbon neutral, using electric energy for transportation can be eventually. Don’t disregard all the solutions which are not perfect but try for gradual improvement.



  • And it is terrible. If you perform this kind of delegation, you have to expect that the other tasks will be shoved back on the priority list and the overall efficiency will decrease. This busy person will need more time overall for the sum of the tasks, because this kind of parallelization will make it harder to work on one task with focus. Also they will burn out eventually. But hey, that’s not management’s problem.









  • Ich lese jetzt nicht wirklich raus, was dagegen spricht einen Arduino verwenden, wenn einen die limitierte Hardware nicht einschränkt. Das war bei denen ja aber gefühlt schon immer so. Es ist halt ein sehr begrenzter Mikrocontroller, aber mit niedriger Einstiegsschwelle und für wahnsinnig viele Anwendungen absolut ausreichend. Ein ESP32 braucht auch ungefähr 100mal so viel Strom wie ein ATmega328. Es gibt mMn keinen Grund, die fünf Arduinos, die man noch in einer Kiste liegen hat, nicht mehr zu benutzen.
