on: Lessons learned shipping 500 units of my first hardware product
My first guess was that they used an external brick for the power supply with a relatively low output voltage--that would eliminate a lot of the CE test load. However, a cursory glance at the product photos suggests the power supply sits within the base of the lamp. Maybe the product developer can shed some more light on this. ;-)

on: Transgenerational Epigenetic Inheritance: the story of learned avoidance
Cells specialize based on the presence of certain chemical gradients, for example. These types of 'signals' that guide specialization already become apparent in a very early stage of embryonic development. I don't think that's part of the realm of epigenetics.

on: The Digital Markets Act: time for a reset
I can’t imagine anyone in my environment becoming really angry over this. Some of them would have to find new time sinks though—-hopefully ones that actually benefit them instead of turning them into commodities.

on: iFixit iPhone Air teardown
Don’t agree with this take; software doesn’t need repairs when you drop your phone, when it is submerged, when it is charged/discharged daily for a few years, and so on. Freedom to use your hardware however you like is more of an ideological discussion, whereas repairs are simply necessary due to the unavoidable wear-and-tear.

on: AI, but at What Cost? Breakdown of AI's Carbon Footprint
If we assume the indicated 400 W load with a total processing time of 20 s per user query, and 20 mio queries per day (‘daily users’), shouldn’t the daily consumption be closer to 44 kWh? (20 mio x 0.4 kW x 20 s / 3600 s/h) Other than that, the energy use for LLMs is obviously substantial. I seem to remember that the operating costs should be fairly evenly split between hardware (i.e., GPU) depreciation and energy costs.
