u320on Tesla's Next-Generation Model Y Chassis

Damage in a collision is a good thing as it requires energy. Not sure why you say a stronger part will reduce injuries.

u320on SARS-CoV-2 escape in vitro from highly neutralizing Covid-19 convalescent plasma (2020)

There is no reasonable scenario under which it goes away at all.

u320on Rust Moderation Team Resigns

The announcement is clear that this is unrelated, it states health reasons.

u320on Rust Moderation Team Resigns

Sure but there is no way for us to know who the wrongdoer is in this case.

u320on Rust Moderation Team Resigns

It is very much in the public sphere now though.

u320on Solar-driven water splitting at 13.8% solar-to-hydrogen efficiency

Maybe in Arizona. In places where clouds is a thing you are looking at weeks of storage. And some of that stored energy would need to be collected months ahead of time. This is simply not doable with batteries, hydrogen storage is absolutely essential.

u320on Solar-driven water splitting at 13.8% solar-to-hydrogen efficiency

The most cost-effective way is a combination of over-provisioning, batteries and hydrogen storage. The exact mix is determined by consumption patterns and local wind/solar conditions. Generally though it's extremely expensive to rely on over-provisioning+batteries alone in places with unreliable weather patterns.

Falling battery prices helps of course but we are very far from a point where we can eliminate the need for hydrogen.

u320on US inflation jumps to 31-year high amid global supply chain crisis

https://fred.stlouisfed.org/series/CPIUFDSL

I'm not saying food prices (even broad baskets like the this) represents inflation. The broad indexes are better for that. But it's not true to say that food prices are at the same level as a decade ago.

u320on US inflation jumps to 31-year high amid global supply chain crisis

Prices are always moving so you can say anything you want by cherrypicking individual categories. That says nothing about inflation.

u320on US inflation jumps to 31-year high amid global supply chain crisis

That doesn't really change much, it's a rounding error in the calculation. The actual number if you compare to the pre-recession peak is 29.7%.

u320on US inflation jumps to 31-year high amid global supply chain crisis

I'm not sure where you are getting your numbers. Food prices are 30% above where they were in 2010 in the CPI for example.

u320on AMD Gives Details on EPYC Zen4: Genoa and Bergamo, Up to 96 and 128 Cores

Place names avoids trademark conflicts.

u320on Led by Tesla, EVs drive chip industry's shift beyond silicon

All EVs are already highly efficient, any further increases is going to be extremely marginal.

u320on Consumer prices increase 2.6 percent

This is the numbers for March. What's the point of posting a month old news? Especially as new numbers are posted tomorrow.

u320on Consumer prices increase 2.6 percent

> Like you said, if you at food, healthcare, education, etc., they are up way more than 3% year over year.

That's how averages work

u320on Lithium battery costs have fallen by 98% in three decades

> There are numerous arguments about how we will always need coal power or nuclear power, or natural gas and they all base it on old studies with obsolete high costs of batteries.

This is simply not true. I'm sure there are some bad articles out there but that's true for anything.

See e.g. https://www.cell.com/joule/pdf/S2542-4351(18)30386-6.pdf where they authors find non-intermittent power production to be necessary even under an assumption of a further 75% drop (from 2018 levels) in battery prices.

u320on Lithuania plans to hold drills in case of accident at the Belarus nuclear plant

> Yet, the regulators still identified a considerable list of issues to be addressed.

This is normal for any plant. Doesn't mean that VVER is less safe.

u320on Sweden Covid-19 Update

No, since in this situation the error is growing exponentially too. There can never be any "catching up" in this case.

u320on Reddit shuts down subreddits including r/The_Donald and r/ChapoTrapHouse

Just because something is hated by most of the left doesn't make it "not left".

RCP8.5 strikes again...

u320on New Query Language for Graph Databases to Become International Standard

> Some RDBs provide extensions to the SQL standard to do some basic graph traversals

This has been standardized since the SQL-1999 standard.

u320on Julian Assange arrested in London

There is no obvious threat of persecution. Facing rape charges certainly doesn't qualify.

u320on USB 3.2 is going to make the current USB branding even worse

And A is always the same socket regardless of version while B is not. It's a mess.

u320on Generics aren't ready for Go

This article highlights very well why designing a programming language without generics is a mistake. Adding it after the fact is not trivial, especially if you have high standards wrt simplicity and non-redundancy.

u320on Tesla Adds Larry Ellison and Kathleen Wilson-Thompson as Board Directors

> You're talking about a guy who has no shame in using a publicly traded company (Oracle) to bail himself out of personal investments gone wrong (See Pillar Data).

Kind of like using SpaceX to fund SolarCity and then using Tesla to bail out SolarCity so that SpaceX bond holdings doesn't go bust?

u320on Using Zig to Provide Stack Traces on Kernel Panic for a Bare Bones OS

Most people do, though.

u320on The down side to wind power

You're not going to be anywhere close to 3 cents in a 100% renewable system without hydro. Cheapest solar price in the US is 2.3 cents but that is in one of the sunniest places in the world, subsidised, and no storage.

u320on SoftBank Succeeds in Tender Offer for Large Stake in Uber

Uber's relative failure in the highly deregulated Swedish taxi market to me indicates that their competitive advantage is avoiding regulations. So it's not clear why "to much regulations" would be a problem for them.

Monsanto is a herbicide vendor, not a pesticide vendor.

Not everything you dislike about the ag sector is Monsantos doing.
