I'm also using it for few years, the only complain I got so far is a lack of proper version for Mac OS and any mobile client. Obviously Python+GTK work on Mac OS, but few times either updates of Python, Mac OS or Zim itself, broke it f

There is quite some misleading terminology being used in the field of nuclear fusion (see excellent overview here [1]). So I was genuinely curious what kind of Q is used in this paper, so here it is: > In this regime, self-heating from α

I have a solution for that: with bare hands close your ears tightly with Airpods in them. Depending on the duration of such covering Airpods either just mute for a moment, or disconnect and reconnect right away. This helps to re-sync if on

Maybe Google Maps just didn't have enough data about that road or there was a jam on the highway. There are a lot of factors to consider and knobs to tune. In old days navigating software was just looking for a shortest possible way, w

For me the enthusiasm part was very important in car DIY forums, communities of which nowadays moved not even to facebook groups but to messengers. Which in a first glance sounds great, since you can be assisted in real time. But in reality

Yes, but the size of the blatter would be enourmous for 250 claimed tonnes: 1 m^3 of air weights 1.21 kg, so if to reach neutral buoyancy you use helium (0.18 kg / m^3) or vacuum (0 kg / m^3, best case), then to counteract lifting

Basically two methods: 1) have counterweights (e.g. as mentioned above for another similar concept Cargolifter which used water); 2) expand its volume during loading and contract after unloading. E.g. pumps compress gas while unloading and

A nice alternative to VPN (especially when you don't have a root to set it up) is using ssh tunnels: ssh user@server -D 1234 and Firefox with socks proxy set to 127.0.0.1:1234 (e.g. using Foxyproxy addon, though possible without it

VW diesel cars can be equipped with Webasto (auxiliary heater which burns diesel). One gets a remote (in my experience reaching up to 500 meters) which can be used to start this heater along with car's climate control. The advantage is

Total losses in case of 1100 kV line can be found as follows. As correctly commented below 3.5% loss per 1000km yields to 58.6% retained power over 15000km. So I will use 41.4% loss on that distance for my napkin calculation. P_total = V_in

True, but what you describe is related to the measurement and sampling accuracy. Until such sensors hit the Heisenberg uncertainty levels of precision on the readout/sensing, such uncertainties may be decreased further, there is no phy

Though website mentions thrust-to-weight ratio of 1.7 for 47.5 kg, so it can lift up to extra 33 kg. There is also a description of a spraying system with a tank of 20 l/kg, so it seems 20 kg is the actual payload capacity.

One of the reasons may be a problem with "disabling" vertical turbines during high winds. With properller-like turbines, blade can rotate to move edge-on towards the wind direction or move parts of blades in the opposite direction
