How feasible is it to drive a 5G (or any G after 3) modem with a low-power microcontroller?

I don't think politicians are bothered about being "heckled" online. I suspect they are fully aware that, as long as they stay out of it, it's us mugs who spend our time "communicating" online, while they set t

Interesting. Obviously anything after 2G cannot really be a "dumb phone", but they have made a good effort at hiding the usual functionality of a smart phone. I'm going to stick to my Nokia 105 for as long as 2G is kept alive

Disappointed. When I read "powering an office", I thought they had found a way to run their business-critical applications and storage on Pis. Now that would be an achievement.

Very curious about the circumstances surrounding this move, especially as the EFF is one of the few organisations taking a principled stance on the state of the internet. There is certainly a lot of doublespeak - the EFF's own news pag

Makes me wonder just what FB will do to Whatsapp to keep the money flowing in, as FB's core app/website declines.

Before you use your laptop or phone, write down exactly what it is that you want to achieve. Then, time how long it takes, and recall exactly what it was you did end up doing. As you say, the results are surprising. I have worked very hard

That would be the most optimistic estimate I've ever seen - do you have a source for it? Assuming 73kg/CO2e per kWh of EV pack[1], an 85kWh EV pack, an ICE that gets 40mpg (and thus 40 miles per 11kg CO2), grid production of 0.30k

I thought drastic measures were needed to slash CO2 emissions, to stave off the Climate Catastrophe? Most analysis puts the lifecycle CO2 savings of an EV over an ICE at somewhere near 50%. Hardly seems worth it, with all of the extra pollu

Do you have any sources for your "ICE uplift" default value of 50%? I'd also be curious to know where you got your numbers for manufacturing CO2 from.

I don't understand why this is surprising. The embodied energy of lithium cells is enormous, and it takes 30,000 miles or more of EV driving before you've paid back the CO2 debt of manufacturing the battery pack (that is, assuming

I'd check your napkin ;) 5% of the world electricity usage divided by wholesale electricity cost, divided by world lithium production in grams -> (5% * 2.5e+16 Wh X $30/1e+6 Wh) / 8.2e+10 g = $0.45 per gram (or 15kWh per g
