It’s an irregularly shaped body so there’s not one single radius. Mean radius is always going to be an approximation (even for Earth); the mean radius of the Moon is 1,737.4 km.
It’s a little misleadingly worded. Looking at the original press release[1] and an earlier announcement[2] I think they mean that they have prototype versions of this panel with 29.5% efficiency, the first production version they’re talking about here isn’t at that level yet.
If the existing procedures aren’t ensuring a safe workplace, the procedures aren’t adequate. Job site safety can add time, and it’s the company’s responsibility to ensure that there is no incentive for a worker to be able to speed up the job by skipping a step.
I’ve worked in places where the safety procedures were clearly perfunctory (drove a forklift in a warehouse for several years, among other jobs) and if I had insisted on following the actual safety procedures I would’ve gotten endless grief from other employees for slowing them down. This is a management failure.
They’re starting to roll out trash containers in the city, should have been done years ago. There’s a bunch of interconnected factors: all residential buildings in NYC get municipal trash pickup (most other cities require private trash service for large apartment buildings), Manhattan doesn’t have many alleys so trash has to go out front, on-street parking blocks larger curbside bins and using exclusively wheeled cans would crowd the sidewalks. They finally decided to remove some parking spaces to allow for large curbside bins.
> “The existing two-day period to settle trades exposes investors and the industry to unnecessary risk and is ripe for change,” Robinhood CEO Vlad Tenev said in a February 2021 release. “There is no reason why the greatest financial system the world has ever seen cannot settle trades in real time.”
There’s important context missing at the end of the article. It came up at the time, but it’s a little ironic (given how much of their business relies on customers trading on margin) that Robinhood was advocating for real-time settlement, since that would dramatically limit the ability of entities to trade on margin. Delayed settlement of T+1 (or even T+1/2) allows brokers to net out trades at the end of the settlement period, rather than needing everything to be pre-funded. It’s not a technical problem that we’re not going to T+0, it’s a policy decision.
I think you’re correct, this recent press release from the cited source (Carers Trust) says it’s 1 million total caregivers under 18, of whom 50,000 spend 50 hours/week caring for others.
My understanding that this is to enable things like a lunar GPS system, which requires the satellites themselves to have precise clocks that are synchronized with each other.
> They also mention the dependence of the SI units on the unit of time, which really suggests the writer has no idea how measurement precision is achieved.
Say more? I thought an accurate clock would be necessary to derive a reference meter and kilogram measurement.
Like if the raw stone is elongated you probably don’t want to cut it into a square finished gem, something like an oval cut would have less waste. And instead of trying to decide on an exact size in advance (like, exactly 1 ct), the final gem is whatever it is when the cutting is finished, so if it’s a smidge over you don’t shave it down.
Automated cutting is used for less valuable stones, or when you need to have multiple stones of the exact same size and shape. Hand cutting is used when you want to maximize the yield, so you use the raw stone to guide the final size and shape.
That’s basically what STIR/SHAKEN is designed to do, what you’re talking about is going to be handled by the certificate authorities. Carriers are ramping up the way they flag or restrict unverified calls as the system is more widely implemented. Echoes of how HTTPS slowly became universal.
I wouldn’t exactly say STIR/SHAKEN isn’t real security. The protocol works fine (like HTTPS), the issue right now is that the Certificate Authority network is still being built out and attestation isn’t enforced by carriers yet. Things should steadily improve now that the protocol itself is deployed.
NYC used to have a lot of Single Room Occupancy (SRO) residential hotels that functioned more like cheap apartments. Rent stabilization applies to buildings built before 1974 and kicks in for residents once they’ve been in a place for 6 months. Years ago the city changed the zoning laws to restrict SROs so there aren’t nearly as many as there were in the 80’s but a few have stuck around.
I suppose it makes sense if you consider that the purpose of these programs is to acquire customers that will potentially scale dramatically in size (and usage of the platform) in upcoming years. Bootstrapped businesses may not look to them like the future cash cows they’re seeking. It’s unfortunate.
“Innocent until proven guilty” is an incredibly high burden of proof that we reserve for criminal trials. In other contexts, this is not the appropriate standard —- civil suits, for example, use a “preponderance of evidence” standard. Non-state actors using a lower burden of proof is entirely appropriate.
They’re progressive jackpots, the prize pool increases until someone wins, at which point it resets. So a ticket for an individual drawing can be +EV if no one has won in a while, with the excess money coming from players in previous games rather than the lottery administrator.
In certain contexts this is called “doing a geographic”. Notorious trap for people who look solely for external causes of their discontent and ignore internal.
The airlines aren’t doing this out of kindness, the Department of Transportation is basically telling them they have to. Officially they’re “encouraging” the airlines to seat families together at no charge, but that’s regulator speak for “do it voluntarily or else we’ll make you”. https://www.transportation.gov/individuals/aviation-consumer...
