This is the AWS hosted service (formerly "AWS ElasticSearch Service") based on OpenDistro for ElasticSearch adding OpenSearch and being renamed.

Slightly new, but certainly not unexpected after OpenDistro was renamed to OpenSearch (They basically changed the name and added OpenSearch 1.0 as an option)

Comment This is not the WIV lab (Score 1) 166

Interestingly, these concerns are about a CDC lab, not the Wuhan Institute of Virology... (I know "Wuhan CDC" is close to the market, not sure if that is the same place as "the Wuhan branch of the Chinese Center for Disease Control and Prevention")

(WIV is significantly further away (~14 km / 9 miles) and is what most of the theories focussed on)

I know Tesla claims "<2 kWh/mile" (That, with the range and the Model 3's battery specs calculates to about a 6 ton battery) (that would be " 1.25 kWh / km" when converted to units used in the vast majority of places)

The industrial loads does not often vary as quickly as the world's truck fleets being connected and disconnected though?

(I do see uses for battery-electric trucks for local deliveries though, long distance just seems better suited for hydrogen (or possibly electrified roads) though. (but the report below seems like it might not be completely impractical, with assumptions about future gains and different weight limits for electric trucks)

This report seems interesting as well. They claim around a 4 ton battery by 2030 and energy consumption between 1.1 kWh / km (2030) and 1.4 kWh/km (now) for battery-electric trucks (which seems similar to the Tesla claims) (It would be interesting to see if battery energy density can make those gains) (They work on a battery with the capacity to do the maximum legal driving time in the EU for a day, with overnight charging, which might be more practical than fast charging)

The power needed to charge a large truck in a reasonable time would likely put huge loads on the grid (storage at the charging station can help though). Some fast car chargers are around a neighbourhood worth of load being added and removed quickly, while a trucks would be closer to a town worth of load... That happening thousands of times a day might need a significant redesign and modification to the power grid for the huge rapid load changes.

The overhead lines spreads the demand out over a much longer duration (And allows for much less of the cargo capacity being sacrificed for batteries - the max mass of trucks are regulated, so batteries means less payload)

Comment Re:By design, like the previous ones (Score 1) 135

True, the design deserves criticism, but the articles almost make it seem as if it is something new that was discovered (that control of the booster was lost), instead it was something that was known before the launch, since the other launch of the same rocket did the same... (But the article as it stands is easier to write and has a more clickbaity title a decent critique would have...)

Comment Re: Not the first time (Score 1) 135

They could probably add a relatively small solid fuel rocket just for deorbiting... (But they'll still need A and C) (It just needs to be able to dip the orbit a bit deeper into the atmosphere in the approximate area of an ocean) (It is certainly a bad design, but not a malfunction (I have a problem that the article doesn't make that clear - it presents it as if it is was just discovered, instead of as a criticism of the design))

Comment Re:By design, like the previous ones (Score 1) 135

Yep, it is not a great design. (Adding a tiny amount of extra fuel or a small rocket (If it is low enough for the orbit to decay quickly enough, not much delta-V should needed to put a higher drag part of the orbit in a predictable place) to deorbit it in a predictable area would have been better). The summary / article leaves the impression that it is some kind of failure though.

The chance of it doing significant damage seems quite low though...

Submission + - SPAM: New Rules Allowing Small Drones To Fly Over People In US Take Effect

An anonymous reader writes: The Federal Aviation Administration (FAA) said that final rules announced in December took effect on Wednesday allowing for small drones to fly over people and at night, a significant step toward their eventual use for widespread commercial deliveries. The effective date was delayed about a month during the change in administration. The FAA said its long-awaited rules for the drones, also known as unmanned aerial vehicles, will address security concerns by requiring remote identification technology in most cases to enable their identification from the ground. Previously, small drone operations over people were limited to operations over people who were directly participating in the operation, located under a covered structure, or inside a stationary vehicle — unless operators had obtained a waiver from the FAA.

Drone manufacturers have 18 months to begin producing drones with Remote ID, and operators will have an additional year to provide Remote ID. The new rules eliminate requirements that drones be connected to the internet to transmit location data but do require that they broadcast remote ID messages via radio frequency broadcast. One change, since the rules were first proposed in 2019, requires that small drones not have any exposed rotating parts that would lacerate human skin.
