readams··on EV batteries alone could satisfy short-term grid storage demand as early as 2030
But this article is not talking about brownouts this is talking about routine use.

readams··on Narco Subs 101 (2020)
In California, the illegal marijuana market continues to thrive because of the taxes and regulation.
readams··on Microsoft workers to form company’s first union in the U.S.
Worth noting that Football is a legal cartel, explicitly excluded from antitrust law. You can't really extrapolate much from it as an example.
readams··on Tell HN: Google Cloud lets anyone add you to a project without your permission
Google cloud is a distant third in the cloud space. So claiming they are a monopoly is frankly pretty ridiculous.
readams··on Japan to invest on nuclear energy in major policy shift
In retrospect there's no doubt the evacuation was an overreaction. Of course, in the moment, it's a harder decision since you have to act on incomplete information.
readams··on US Department of Energy: Fusion Ignition Achieved
This works in a totally different way, by heating a tiny target fuel pellet with a laser to cause it to collapse and trigger fusion through basically heating and squeezing: more like how a bomb works. It's not easy to see a direct path from this approach to a power plant, but it might involve lining up a steady stream of fuel targets and doing this in a sort of pulsed mode.

Other approaches attempt to create a continuous plasma where fusion can occur confined in a powerful magnetic field, and heated by radio waves to get it going. So there's always fusion happening rather than in short bursts.

readams··on Highway EV charging will soon need a ton of power
You're assuming something like 24 hours a day of having the car parked in full sunlight, which is not realistic (even ignoring that night exists). For it to make sense, you'd need the solar arrays on the car to provide a reasonable percentage of the energy needed during driving. If this isn't the case, you're way better off putting the solar panels somewhere other than the car (where they can work much better), and charging the car when it's not driving.
readams··on The five-year engineering feat Germany pulled off in months
Trump would often get things right but for the wrong reasons. I call this the "Donald Trump stopped clock principle"
readams··on Highway EV charging will soon need a ton of power
Even converting the whole surface of the car to ideal 100% efficient solar cells world be nowhere close to enough, unfortunately.
readams··on Starshield: Secured satellite network for government entities
Cooling is actually a big problem in space.
readams··on The Pentagon fails its fifth audit in a row
It wasn't that long ago that I was hearing about how audits were impossible at the Pentagon and they would just give up whenever it was attempted. This sounds like progress.
readams··on Effective Altruism Is about Getting Rich with a Clean Conscience
Defining what is really good and bad is a very hard thing to do, and has been the subject of philosophical debate for millennia. It gets really hard when we try to construct a reasonable logical foundation for ethics, but then we always check it by comparing it to the intuitive ethics in our evolved/cultured meat brains. Of course, the intuitive ethics always "wins" and we conclude that the problem must not be there, but any conflicts must be problems with the ethical framework!

So you can conclude that you should just do whatever makes you feel good and all ethics are nonsense as you seem to prefer, but I'm not sure that you've really refuted the basic premise that you should try to maximize the amount of good you can accomplish.

readams··on In defense of linked lists
Linked lists are great. But they have the problem that, almost always, whatever problem you're trying to solve would be better done with a regular resizable vector.

This includes problems that they should be great for, like insert into the middle or the front.

The reason is that in practice the way computers actually work is that there is an enormous time penalty for jumping around randomly in memory, and it's large enough that it's often worth paying a O(lg n) cost to switch to something that will be contiguous in memory and allow the CPU to prefetch data.

There are exceptions when you really should use an actual linked list, but your default should be a vector and not a linked list.

readams··on Kill Bill – Open-Source Subscription Billing and Payments Platform
Lago is AGPL so no go.
readams··on Google engineers joked about how incognito mode isn't incognito
Google does not collect any information through Chrome though in incognito mode. Google can see your activity if you visit Google in an incognito window, but any web site can.
readams··on 5G’s Rollout Rattled Hundreds of Pilots
No the altimeters are sensitive to frequencies outside their band. So 5g transmitting inside its band causes the altimeter to malfunction.
readams··on Most PPP loans have been forgiven, despite signs of possible fraud
PPP loans were always supposed to be forgiven from the beginning. Nobody would have taken the loans otherwise. It was not really a loan it was a payroll subsidy to keep the economy from collapsing.

Also, this was actually authorized by Congress and not declared by fiat in an enormous executive overreach.

readams··on Project Starline expands testing through an early access program
The experience is as if you're looking directly at a person sitting across from you. There is no camera offset.
readams··on Project Starline expands testing through an early access program
I've personally tried a prototype and it's actually pretty impressive. You get a fully-3D life-size person sitting across from you. The rendering is not 100% perfect, but it's close enough that you're not in any sort of uncanny valley. The main problem is that it's really a 1:1 thing.
readams··on Calif. Law to Protect Children's Privacy Could Lead to Invasive Age Verification
It's the last one. It's just very poorly drafted legislation that hasn't been thought through. this is our one party rule in action. With no meaningful opposition, laws are not scrutinized and unintended consequences never considered.
readams··on Granting Pardon for the Offense of Simple Possession of Marijuana
This action has one major thing going for it that many executive actions lately have not had: it's actually legal for the President to do this.
readams··on AWS us-west-2 issues
I think consumer smart locks still let you use the regular lock if the power is out.
readams··on Target Venus not Mars for first crewed mission to another planet, experts say
Avoiding the need to wait 26 months between launch windows certainly reduces the degree of difficulty. Going from "oh we wish we had X that we didn't think of" to having it is literally almost 3 years on Mars.
readams··on AWS vs. GCP reliability is wildly different
Borg is not used for gcp vms, though.
readams··on Checkout trader's joe logo on Google
Don't see the Biden logo, but I happen to be traveling in France and the top result is perhaps even worse: https://imgur.com/a/SdCrl8G

Crypto scam spam

readams··on UBS, Wealthfront Cancel $1.4B Deal
Those funds have higher costs. If you want to do that (and it's a good idea) look at the portfolio allocation and then buy the ETF version of the underlying assets.
readams··on Apple overtakes Android to pass 50% share of smartphones used in US
For me iPhone UX is confusing and inconvenient. There are a million shitty decisions embedded in the interface.
readams··on JavaScript hydration is a workaround, not a solution
I would say gmail is the most bloated SPA pretty much in existence much less at Google.
readams··on Gen Z have 86% less purchasing power compared to baby boomers in their twenties
They've specifically pulled out only the categories that have risen faster than inflation, and didn't include any categories that have fallen relative to inflation. So it's guaranteed to get this result.
