No, you need to warm the battery first only to charge it. This is why Tesla disables recuperation during initial drive with cold battery. When it is cold it only has reduced capacity + current but that does not matter as during winter you do not need super-sport accelerations; and after 30 mins of driving it gets a normal temperature from invertor+engine heat so that you can utilize its full capacity.

Comment Re:Duo or Allo? And where is text chat? (Score 1) 150

Hangouts is still XMPP. I use it daily against Pidgin XMPP. Allo and all other proprietary IMs use UDP-based communication. XMPP uses TCP. I have been using XMPP-TCP for years fine but then I used it once abroad on a 3G/LTE network with all its temporary drops and Hangouts/XMPP became unusable, it even got stuck for whole night. Maybe Google has some bug in Hangouts as even TCP with keepalives should timeout in at most several minutes - although that would still be unusable in practice - this is why UDP is used by the commercially successful IM protocols.

Comment Re:90%? (Score 1) 61

The supercharger cables get warm but they charge at 150 kW. Tesla has been experimenting with some supercharger liquid cooling according to googling. But 90% is not just about the cable, probably most of those 10% is lost during the chemical charging of the battery itself. And Tesla battery HVAC runs on full power when the car is being supercharged.

I do not advocate the wireless charging itself, that is a non-sense IMO.

Comment Re:Desktop Windows has more users than X11/Linux (Score 1) 403

Android is not Linux OS (AKA GNU/Linux). Android is Android OS - it has its own Java API. It runs on Linux kernel but it could run even BSD kernel and nobody would notice. Android does not even run glibc. I do not know much ChromeOS but it is also not a Linux OS. Are there apps like LibreOffice, Balsa, GIMP etc.? No, they run only web applications (even offline). Not even trying to talk about Linux commandline applications. There is no Linux desktop as while I like Linux apps it is obvious general users dislike Linux apps for some unknown reason.
