"Hover over text for description ..." does not work on tablets. And the displayed badges are heavily distorted in the vertical direction. That's while reading this with the Materialistic app on an Android device.

What's wrong with dired mode? Ok, you'll get each directory in its own buffer. But, thinking of that, it shouldn't be to hard to make dired mode recurse into subdirectories inside the same buffer. (And fold/unfold like o

How does LineageOS stop the "little black box" which handles GSM/UTMS/etc traffic from spying on you? Or your telecom provider from tracking you? Don't get me wrong, I like these free OS versions, but while I could

by jcynix 5y ago
Both the hardware vendor and the vendor of the mobile phone's "black box" talking to your telecom could, of course. Potentially some chips inside could do nasty things, even if you'd install LineageOS for example.

I'm running Netguard (app) as a firewall on them, set to block all traffic and then allow traffic only for solid apps where I need/want traffic to happen. Works like a charm, can even log in pcap format to analyze traffic.

That's correct. I was comparing our system to existing systems which directly use a refrigerant sent into the ground loop. Our heat pump itself is a closed system just as a refrigerator, and works indirectly via the water cycle used ou

Energy is specified in KWh here, i.e. we have a metering system installed which states that our heat pump delivered 128024 KWh of heat and the electricity company's metering system tells me that it used 34844 KWh of electrical energy t

We did have no problems as the ground below consists mostly of clay for at least 100 meters. Two times at 60m was a political limit 10 years ago, because at 100 meters "suddenly" mining rules applied. The tubes are about 100 mm in

There's no refrigerant here. Our heat pump uses plain water mixed with an anti-freezing agent. Just like the cooler in a car does. And there are control displays where you control all operating parameters. As for the "pump heat fr

Our house (with a ground based heat pump) uses active ventilation with heat exchangers (and pollen filters) and as a result we have better indoor air than we've had in rented flats in all years before.

by jcynix 5y ago
Good heat pumps aren't of the air conditioner type. Our heat pump uses two 60m deep drilled holes. Thus heat exchange happens in the ground, which is always more or less 10 degrees Celsuis. Heat exchange in the house happens through fl

Not everyone is using a flatrate and thus both crash reporting and telemetry might cost the sender some money (or calculate against their hugh speed quota). Some people seem to expect that data transfers are always free ... That's one

Remote preheating? I prefer a little more work-life balance, i.e. cook when I'm at home. And use the (rather short) time for preheating to look at the paper mail or mix a drink. Or stroll through the garden for some minutes. Other appl

Besides that bash has its problems with array variables. Unless I switch to one of the "real" scripting languages, I use zsh too and start my scripts with if [[ -n "$BASH" ]] ; then echo $0: use zsh, not bash

Fluid honey mainly is fructose, the one which crystalizes easily is mainly glucose.

> Does fruit contain as much fructose today as it did 50, 100, 200 years ago? Maybe due to selection of larger, sweeter fruit, yes. But processed food contains various sugar variants, including fructose (think "high fructose corn sy

Raw fruit isn't a problem, not even for humans. Products where "sugar" is replaced by fructose or other, simpler sugar variants is. Various sugar substitutes are added to e.g. canned fruit in "juice" which is most

I don't know about bash, but zsh allows you to define a shell function "zshaddhistory" which is running right before a command is executed.

You could deduce the working directory from the sequence of commands in your history file, so the working directory is implicitly contained in the history file. I don't remember an option to save the working directory explicitly. But z

Modern shells are powerful enough to help you remember, if you learn to configure them appropriately. My histories are always saved because each shell instance gets its own HISTFILE, like so: export HISTFILE=$HOME/.history/${T
