Good catch, sorry should have corrected that. While not small for a machinist, I think by the average persons definition that is a pretty small gap for the oil to occupy ;-)
The bearing surfaces in an engine (ex: crankshaft main bearings) have very tight tolerances, usually in the 15-25 thousandths of an inch. The engines oil pump fills those tiny gaps with pressurized oil which allow the metal surfaces to spin thousands of times per minute without damage.
This is also why if you have any issue with oil pressure (ex: oil pump failure, cracked oil line) or oil starvation (ex: driving a regular car on a race track, cornering forces slosh oil away from the oil pickup in the sump) issues, you'll damage your engine nearly immediately.
I'm confused as to why they've allowed the data center power drain (which they knew was going to happen) to cascade into consumer power prices. Surely they should be charging consumers their existing price and charging the data centers an increased price based on their massive usage.
Without some sort of mitigation, the costs keep rising and it'll drive families away from these cities and/or counties to avoid the cost hikes. This is akin to what we're seeing in a lot of major cities with rent, people are living further and further away from where they work, paying taxes in other forms (time, public transport costs, gas costs for their car inc. wear & tear, etc).
If it is reasonable to have your privacy in a public place, does this mean that products like Flock which indiscriminately violate your privacy would now require a warrant for law enforcement to access (currently they do not)?
The most efficient use of a roundabout is to indicate when you're turning across the roundabout (turning left if you live in the US) and when you exit (whether that is the first, second or fifth exit). This way all traffic entering the roundabout on an entrance ahead of you knows your vehicles intentions & it allows them to treat the entrance like a yield/giveway instead of a stop. #keepthetrafficflowing ;-)
I don't think roundabouts are complex, treat them like a giveway/yield and they are brilliant.
The biggest issue is they are an infrequently used traffic control device in the US. So infrequent, I don't think they even appear in the WA drivers handbook which is kind of shocking.
As a by product, you see the craziest driver behaviour in Seattle on them:
1) No one uses their indicators/turn signals as they approach. This is a major issue because it makes the roundabout incredibly ineffective, as every driver needs to treat it effectively like a 4-way stop because you don't know the intentions of the cars around you.
2) Drivers will enter the roundabout, then stop at another entryway if a car approaches. This makes no sense, as the approaching car would need to yield or stop, so it slows the traffic down again.
3) Drivers will wait at an entrance until all other cars are clear of the roundabout before entering. Again, makes no sense - you wouldn't do that on a cross-road if two cars were both indicating right etc.
Definitely need more driver education on the humble roundabout!
I love the idea of hierarchy of intimacy, that is a great concept/phrase.
I'd make it so you could tap a phone, you know their phone number, you know their email. Importantly in my eyes, you shouldn't be able to navigate to a profile and just ask to connect as that'd mean you could do that to people you don't actually know (whereby knowing is inferred by you knowing some amount of their personal info such as tap, phone, email).
I'd stay away from your last option of 'other platforms', per my other reply below in that those platforms allow you to connect to anyone/anything. There is nothing in them that say this connection is inherently personal vs being generic.
In my head, the new Friendster owner wants to drive some amount of true personal connection - hence the tapping.
The problem I see with not using a phone number as I described, is that you'd be connecting to any old social profile - could be Messenger, WhatsApp, Instagram, LinkedIn, etc.
None of those are inherently personal, it'd open up Friendster to be not materially different to any other social network as those networks don't have the concept of a personal connection - they are just generic connections (some are personal, many/most are not).
