    @AccidentalFourierTransform: How about explaining why you think it's off-topic? It seems obviously on topic to me.

    @AccidentalFourierTransform While it is not clear cut ( maybe a topic for meta) I would happily class this as a "experimental design" question as it is clearly physics equipment meant for some experiment. This would put it squarely on topic for the site as per the help section. Equally other similar questions have been posted before and been accepted e.g. physics.stackexchange.com/questions/298079/…

It looks like an induction coil with the make and break device at the bottom and a switch right at the bottom. If you connect it up to an accumulator be very, very careful as the output between the two ball when separate could be lethal. Also the electrical insulation elsewhere may be poor and you might get a shock just by touching the switch.



Use with very great care and preferable have somebody who knows about such devices with you.

What visual should I use to simply compare current year value vs last year in Power BI desktop

Image
0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

How to ignore python UserWarning in pytest?

Image
up vote 1 down vote favorite I am using openpyxl for parsing .xlsm files, and pytest for testing. When I open a file, I get the: OpenPyxl -> UserWarning: Data Validation extension is not supported and will be removed That is not really a problem bcs. program works and I can't change the .xlsm file to fix that. But... When I run pytest with something like: def test_wrong_file_format(): assert check_excel(open_excel('file.xlsm')) == True I will get the warning i mentioned altought check_excel(open_excel('file.xlsm')) returns True and the test should suceed... Is there a nice way to tell the pytest that "It's not a bug it's a feature" and tests should pass even when they get this warning? Is there other way than using something like: with pytest.warns(UserWarning): ...
