Many motorcycles didn't come with cats in the 2000s, combined with lots of high strung 600s running massive valve overlap.
But the modern class of commuter bike has got to be pretty good.
Drag coefficient is poor but they're also a much smaller area, and city driving is more forgiving for aero.
This is a key point. Fuel consumption on my bike goes from about 22km/l all the way up to 15km/l if I increase my speed from 70km/h to 130km/h. Essentially the killer is wind drag. I'm riding a bike with notably poor aerodynamics, I suppose sport bikes do better in this regard.
Be interested to know which part of it is fake news eh.
The culmination of the recent tweets and actions presents this as having more of a personal tone than a grand indictment of big companies relationship with open source.
Additional power draw on the accessory circuit places increased load on the alternator which in turn causes the engine to run a little harder than it otherwise would. Thus burning a little extra fuel.
They produce based on current draw, but have a maximum output, usually around 60-85a for and older car, to 120-240a at 14.4vdc for a newer car or truck. There is no permanant magnet, so the coils require power to generate power. Its quite interesting.
Further to this the 12V battery effectively acts as a big capacitor while the car is running, to smooth out the power that is available.
I found this out the hard way a couple of years ago. My 12V was dead, yet I managed to jump start the car and get it running. I thought it would be ok to drive to get a new battery, as long as I kept the engine running high enough. After a couple of km the dashboard lights started to dim, so I tried reving it as high as I could, but the battery wasn't able to buffer the power and supply the ignition system, so the engine stopped. It was rush hour and I was in the middle lane, so it wasn't a particularly fun wait for the tow truck.
In the old days of lower power alternators (or really old days of generators), and lower power engines, the revs would drop noticeably, and the note change, when you turned dip lights on, aircon or even occasionally - in smaller cars - the heated rear demister! Made it very obvious the engine was working harder.
Now that tickover and fuel injection is computer controlled or we have EVs, and there's a far heavier electrical load in all cars all the time, you never notice any more. They all take power, and decrease fuel efficiency.
Can anyone else comment or corroborate this?
I don't disbelieve you but it's a gigantic if substantiated and would definitely get me to leave the platform.
The DHT performs poorly for unpopular hashes, cold starts and with poorly configured networking. Particularly the last point, an open udp port is required for best results.
No. You need to match all the metadata in the info part of the torrent file, the final hash is a hash of that info dictionary. The fields you lack are largely name and piece size, but without the original file you cannot create the hash of each correctly sized piece. If you have the constituent file (not just it's sha1) you could eventually get it by trying common piece sizes and knowing its name.
i think its worth noting that at least the summary presented on this page could be sliced into two sections
1: different usage of accessories to make the occupants comfortable, e.g. warming up interior for longer, running heated seats...
2: physical changes that affect the overall car: denser air resistance, higher rolling resistance..
the one point that is specific to an ICE engine is friction from running colder oils, the rest seem to apply to both ICE, hybrid and electric vehicles, the latter two more so.
overall the takeaway seems to be that most losses in an ICE vehicles are not about the powertrain, whereas a hybrid/electric vehicle has almost all the losses of an ICE vehicle but with significantly more battery degradation.
