There's a mechanical door handle on the interior.

If you run out of batteries completely and need to get in the procedure is:

1. Open a small panel on the front and apply 12V to the emergency cables to unlock the frunk (this only works if the car is powered off as I understand)

2. Jumpstart the car's low voltage battery, located under a panel under the frunk

3. Unlock and open the door normally

4. Attach an EVSE charger to get the HV back online as well

Tesla cars support:

* Unlock by NFC keycard * Unlock by bluetooth using the app * Remote start by app (over the cell network)

AIUI the latter was down. I don't think the bluetooth would be down - that one works even without cell service - but I didn't try it during the time of the outage. Regardless, you really should carry the keycard around just in case your cellphone runs out of batteries or something.

I have the 2021 model 3, you have a physical button to fire them off once (and to do the cleaning cycle), but to manually set the speed you need to use the touchscreen. There is an auto mode, of course, but sometimes you do need to adjust it manually.

Windshield wipers.

Or just market manipulation.

Prime numbers are expensive to generate and writing a reasonably efficient factorization algorithm isn't that easy either. It's far faster on the server side to just spit out a nonce and have the client generate a partial hash collision up to an arbitrary number of bits (ie, the same proof of work many cryptocurrencies use)

All flight controls on the A330 are fly-by-wire - they're connected via computers. The most critical surfaces have secondary, dumb controllers that can take over if the primary flight computers fail, but less critical systems may not be connected to those backup systems - it's expected that a triple fault of the primary flight computers should be very rare, and manual braking is available as a backup after all.

The new URL (at bloomberg) seems to be paywalled. Is there an alternative link?

Orders are generally quoted in cents, but trades execute off-book at fractional cent prices on a regular basis (e.g. when a HFT firm is providing price improvement).

mRNA vaccines have been undergoing active research for decades, and in particular the lipid nanoparticle delivery mechanism used in both the Pfizer and Moderna vaccines was first used in 2018 in a (non-vaccine) drug called Onpattro[2]. Without this technology, Moderna in particular was having issues with excessive side effects as late as 2017[1].

As such, the Covid-19 vaccines from Pfizer/BioNTech and Moderna could not have been developed pre-2018, and - absent a deadly pandemic that requires taking extreme measures (such as using very large trial groups) to hasten the timeline - normally vaccines undergo development over a period of many years[3] to collect sufficient data to ensure effectiveness and to ensure that the long-term side effects are well understood. Moderna in particular was, prior to the Covid-19 pandemic, working on developing vaccines to target cancer using mRNA technology[4]. Had the pandemic not occurred, one would therefore not expect to have seen any approved therapies until the mid-to-late 2020s at the earliest (and probably later, given how often vaccines and other drugs fail in human trials).

In short, the issue was not that pharmaceutical companies were disregarding the technology, so much as simply the last remaining breakthrough needed to be made - and now that mRNA vaccines have proven themselves to be safe and effective, there'll be no shortage of effort to apply them to new diseases.

Claims are read in the context of the body of the patent and generally known and/or cited knowledge in the field in question. As long as you define precisely what you mean by your terms in the body, you can be as succinct as you want in the claims.

First, is a tweet even a thing you can own, legally? You can own the copyright and you can enter into a contract where you promise not to delete it, but a tweet is ultimately something that is displayed and processed by, and exists at the pleasure of Twitter; they're not a party to your NFT shenanigans and therefore not bound to any of it.

As for the hypothetical contract not to delete it yourself, you'd probably have a good argument that there was no clear meeting of the minds - without an explicit description of what the author intended to be bound to by selling a NFT you'll have a hard time getting the courts to enforce anything about it.

The problem with trying to use the DMCA for this is that, provably, no human creativity is involved, and so it's likely that the output of this is uncopyrightable.

Unfortunately, storage of electricity is quite difficult; supply and demand therefore need to be balanced at all times. An oversupply (ie, overvoltage or excessive frequency) will damage equipment, so prices go negative to encourage those plants which can go offline quickly to do so; generation stations which take longer to shut down or start up, on the other hand, tend to stay running.

In the financial industry collateral is normally used as the primary means of mitigating counterparty risk as it avoids adding an additional counterparty that you then have to evaluate for creditworthiness, and you have to pay them money instead of just temporarily handing over collateral and getting it back 100% later on.

That being said the collateral doubles as a sort of insurance; if one party's collateral is insufficient to cover the loss, the excess is spread across other market participants. This is one reason why client funds can't be used for this collateral.

The NYSE is one of the stock market centers in the US (yes, there's more than one). It's a place where you (usually virtually these days) go to agree with someone on the specifics of the trade - buy 100x GME at $420. The DTC is involved with what happens next - actually exchanging the stock and cash. In particular, they keep the records of which brokers hold how many shares of which stocks.

There's more than one clearing firm in the market. The more money the clearing firm has, the more likely it'll be able to continue trading highly volatile stocks at high volume. Fidelity, as a huge financial firm that's been around for a while, had the assets to afford to keep trading it (and/or their customers weren't trading enough to put strain on them), robinhood (which has its own, small, clearing firm) couldn't, simple as that.

The liquidity issues arise in part when trades occur on unsettled securities. Consider what happens if someone buys a stock, then turns around and sells it the same day to another counterparty. The broker has an IOU from one party for the stock, and has issued an IOU to another party. Two days layer, if the first party fails to deliver (oops, a short seller couldn't find stock to cover their short!), the broker's on the hook, at least in the short term.

The lowest possible price is also the point where the value of your portfolio is lowest and the margin call is most severe. It is completely normal for brokers to immediately close positions when you are highly leveraged and the market is moving quickly on a direction which might leave your portfolio at a negative value - they don't want to be left holding the bag if you take too long to respond. Generally your broker will only give you time to correct things when volatility is low enough that things won't change over the next few hours.

There are two ways to do clinical trials on vaccine effectiveness. One is to vaccinate someone and then deliberately infect them; this gives you good data quickly, but due to the deadliness of COVID-19, this is generally regarded to not be an option. Another is to vaccinate a very large number of people and wait to see if they get sick with the virus from natural exposure. This is ongoing right now on a very large scale; millions of people have been vaccinated, and sooner or later people will come in contact with these new variants. However, it takes time to collect enough data with this approach to provide useful results, and in this case it can be confounded by the lack of a control group (you don't know how many exposure events happened that did not lead to infections).

Regardless, the current vaccination campaign is highly effective against the original - still very widespread and deadly - virus, so it's worth getting it, and as people get vaccinated with it, it will eventually be apparent whether it works against various variants as well. If it doesn't, it's likely that a booster vaccination can be developed for these variants (and indeed, Moderna has begun work, as an insurance policy, on a booster for the south african variant).

This study was done in a laboratory based on blood samples and does not directly equate to a percentage effectiveness. Collecting data on actual effectiveness in the wild, as it were, will require a sufficient number of vaccinated people to come into contact with the variant strains in question, and will therefore take a few months, most likely.

Converting between different grid frequencies would need a rectifier/inverter or rotary converter - and one that can handle high power (1200W+ sustained) as well. That's quite a bit of equipment to run just a microwave...

Edit: Looks like units capable of dealing with these kinds of power specs run for around $2300 USD, e.g. http://www.gohz.com/2kva-frequency-converter

Youtube playback also seems impacted (the front page loads, but videos don't play).

When you hold your breath, oxygenated air remains in your lungs. This allows you to maintain consciousness for potentially a minute or two.

In a decompression event, the air is sucked out of your lungs. The air that remains has a low O2 partial pressure, and so oxygen can leak from your bloodstream into your lungs. As such the body's normal mechanisms for storing oxygen simply don't work.

I suspect that the with the current electrical system on airbuses, the emergency electrical configuration wouldn't have enough power to run all those image processing computers at the very least (dual engine failure would cause this). However that could be resolved with additional battery capacity.

A more likely cause of automation failure would be failure or disagreement in the various sensors on the plane. These are typically triple redundant, but there have been cases where, for example, all the pitot tubes ice over and airspeed indications are lost. There are ways to deal with this but they're not currently programmed into the autopilot.

Other possible causes include failure of major flight controls requiring workarounds - eg, dealing with a stuck rudder with deliberate asymmetric thrust.

That being said flight control issues can probably be dealt with, if necessary. The real problem is with dealing with ambiguous situations where you have to weigh risks.

Consider: your radios are out. Per standard procedure you should proceed on your flight plan to the final fix and hold until your scheduled arrival time. However, fuel consumption is high - you're not sure, but you might have a slow fuel leak, and your destination has dicey weather. Do you divert without clearance or risk that you might be marginal on fuel at your scheduled arrival time?

Where immediately is generally measured in seconds (with the exception of perhaps autoland). Normally the autopilot will have the plane trimmed at all times, so the plane will continue flying its current course for some time without control inputs.

Others have pointed out limitations on register read bandwidth and other possible hardware level issues, but I'll also point out that avoiding indexed addressing modes in the generated assembly doesn't look to be that difficult - if you're doing a big unrolled SIMD kernel it's probably not a stretch to have the compiler emit some LEA instructions as well to avoid indexed addressing modes in the loop. Apparently the compiler authors simply haven't decided that it's important enough to do so yet, but compilers are much easier to change than hardware...

Ideally, yes, but if you didn't have a suitable respirator already you're going to have a hard time finding one now.

I imagine you fill it out as accurately as you can with the information you have at the time.
