It is an uncomfortable risk for many, to back a likely long term winner over a sure current cash cow. Even if their own estimates say they should go for it. See it all the time. And to make it even more short sighted,…

Somehow we collectively forget/ignore that coal power releases many times the radioactivity of nuclear power, and that is just dumped directly into the air. The numbers are not directly apples to apples but absolutely…
As long as the checklist catches more costly errors than the time to use it and the (very likely) negative secondary effects to critical thinking and innovation. Love tools that help, eg checklists, when used right. But…
I wonder about the actual numbers here, and how they vary between cultures, regions, age groups, etc. From what I see from my single female friends 20% is waaay too high. Not trying to be a jerk here, just observation.

I prototype in python or whatever, then, if the project survives into market and has legs I either buy more hardware or rewrite the expensive parts in C++. Reduces calendar time, risk, cost. And I'm likely to make…
Offload to local device with, yes. Offload to server farm elsewhere ... naaah. You have at most a few ms to compress - stream - decompress - refresh. Any latency, jitter, stutter, etc has a very negative impact in vr.…
Do you have numbers of the percentage of people who do get motion sickness from vr? Perhaps 50% of the population not going vomity is a large enough market? Perhaps 10%? As devices get better the market will grow. I can…
Even in super socialized Sweden the first child costs around 180 000 USD (2021) [1] for the median example family. Second child is probably less expensive. [1]…

ymmv: if "the cause" has technical or scientific elements and you are a skilled engineer or scientist your contribution of 1000h/y work on target is significantly larger than donating $1M/y.
if the load bearing core is miniscule and light you have plenty of mass and radius available for abrasion resistance, handling properties, etc ...
Profiling code optimisation in joules is a fun and somewhat unusual task. Surprisingly it has come up both for the high end in a supercomputing project and at the very low end embedded. Having an execution budget in…

The "embodied energy" calculation is always going to be somewhat arbitrary based on what one wants to include. With more or less relevance. E.g: human rest power is ca 100W at ca 20% efficiency. The agricultural…
