Hose that retains water when disconnected ?

Most hoses are open at the end when disconnected, so the water just pours right out. Not such a problem for lawn work, but it can make a bit of a mess when disconnecting hoses inside, like washing machine, dishwasher, and the fridge ice-maker. Besides using a bucket and a mop and holding the end of the hose up, are there connectors that work line gas lines connectors, and keep the contents inside ?

Assuming you mean the single shut-off valve version, not the free-flow version, then yes, that sounds like what I mean. Thanks. SinisterLefty (talk) 01:20, 24 October 2019 (UTC)[reply]

Standard quick connect fittings for garden hoses (like this one [2]) don't allow water to flow through the large female connector unless a male connector is inserted into it. CodeTalker (talk) 15:21, 24 October 2019 (UTC)[reply]

Missing questions

There were two questions asked yesterday concerning Greta Thunberg. Where have they gone. Who deleted them and why? Thanks Anton 81.131.40.58 (talk) 08:10, 24 October 2019 (UTC)[reply]

For the who, click "View history" at the top of the page and see for yourself. For the why, see WP:BLP, which applies to every page on Wikipedia. Please don't do it again, or admins will start blocking your IP addresses. --Dweller (talk) Become old fashioned! 08:48, 24 October 2019 (UTC)[reply]

Is it possible to go back and see what was said and how this was edited [personal attack removed by Dweller]? — Preceding unsigned comment added by 81.131.40.58 (talk) 10:06, 24 October 2019 (UTC)[reply]

You can use the History button at the top of the page to step through every change made on the page, and see the state of the page after each change. SinisterLefty (talk) 10:30, 24 October 2019 (UTC)[reply]

Wikipedia is not for political agenda discussion or personal attacks. If you continue you risk being blocked. JIP | Talk 10:57, 24 October 2019 (UTC)[reply]

Another editor has now deleted the offending revisions, so they won't be visible in the history any more. --Dweller (talk) Become old fashioned! 11:27, 24 October 2019 (UTC)[reply]

To address the OP's question, that stuff was deleted because of being BLP violations [personal attack removed]. ←Baseball Bugs ^{What's up, Doc?} carrots→ 02:33, 25 October 2019 (UTC)[reply]

Fuel efficiency (auto milage)

All else being equal, does the standard fuel-using car travel further on higher octaine gas (petrol) than on “regular” gas?DOR (HK) (talk) 19:31, 28 October 2019 (UTC)[reply]

As long as you are using the minimum-required octane for the vehicle, no, though this is a common misconception. Octane rating: higher-octane fuel can be compressed more without autoignition; engine knocking occurs when the fuel detonates prematurely on its own (due to being compressed and heated), rather than by the spark plug. High-performance Otto cycle engines typically have higher compression ratios, which means the fuel needs to withstand higher pressures and temperatures without autoigniting, meaning a higher octane number. Putting fuel with a higher-than-required octane number in a typical engine does nothing other than make the engine burn more expensive fuel; the engine is incapable of compressing the fuel more, which is what is necessary to achieve better performance. (I'm sure there are some exotic engines with adjustable compression ratios, but of course you specified a "standard" vehicle.)

Potential article improvement: anyone think octane number or another article should state this explicitly? --47.146.63.87 (talk) 00:46, 29 October 2019 (UTC)[reply]

Also you need more energy to ignite it, which is drawn from the battery, whose power is in turn refilled via dynamo by burning fuel. So you'll actually get slightly worse mileage. You need to have good enough gas to avoid unpredictable autoignition since the power it creates doesn't go fully into turning the crankshaft but is wasted on the engine walls (and causes long term damage), but once you've minimized the occurence of that there are no benefits on mileage for using better and better gas. 93.136.155.134 (talk) 01:32, 29 October 2019 (UTC)[reply]

Computers that adjust compression via timing are not exotic. For example, the very common Dodge 5.7 V8 has variable timing (and it shifts into 4 cylinder mode when all 8 aren't needed). 2600:1004:B022:5255:7A88:5987:105B:29D9 (talk) 09:44, 29 October 2019 (UTC)[reply]

Featured Article

The front page of Wikipedia shows the death date of "Sir" Jimmy Saville. Is this vandalism? Surly we would not show him as a featured person and someone of worth due to his paedophilia? His misbehaviour is also not mentioned in the block of text that comes up when you hover over his name, but rather speaks about his charitable efforts, I would imagine these have been overshadowed. Also, has he not been stripped of his knighthood yet? Thanks Anton 81.131.40.58 (talk) 08:37, 29 October 2019 (UTC)[reply]

Being a featured article only requires that the subject be notable, not that they be "good". This isn't unique to Wikipedia. Time Magazine once named Hitler the Man of the Year: [3]. So, it's basically "Most Significant Man of the Year", not "Best Man of the Year". SinisterLefty (talk) 08:57, 29 October 2019 (UTC)[reply]

I understand that, but still... Anton 81.131.40.58 (talk) 09:22, 29 October 2019 (UTC)[reply]

And to prove that very point-that notability is not necessarily for the right reasons, the front page also shows for 'On this day' the birth date of Joseph Goebbels... Lemon martini (talk) 10:52, 29 October 2019 (UTC)[reply]
