It’s not quite as crazy as it seems. The older/larger floppy disk formats were more reliable due to their lower track density.

There was more surface area per byte of data. The old floppy disks could be written once and read for years in harsher environments. New floppy disks we more prone to failure after a few years.

Yes that’s correct.

To be more clear, nuclear waste is only a small percentage of the hazardous waste we’ve been disposing of by permanently burying it.

Yes. Nuclear waste is tiny. That’s the point.

Nuclear isn’t the only hazardous waste we dispose of burying it.

We’re disposing of tonnes of hazardous waste daily. Only a tiny percentage of that is nuclear waste.

Yet for some reason everyone loses their mind about the comparatively tiny amount of hazardous waste from nuclear and no one cares about the significantly larger about of hazardous waste from the eventual disposal of solar panels and 100s of other sources of hazardous waste.

For over a century, the standard way we’ve been disposing of hazardous materials that can’t be easily recycled is to permanently bury it. We’re doing it with thousands of tonnes of hazardous materials daily.

A nuclear power plant only generates about 3 cubic meters of hazardous nuclear waste per year.

At the typical sizes we’re currently building them, you need 50-100 solar or wind farms to match the electricity output of a single nuclear reactor.

When we eventually dispose of the solar panels from those farms we literally end up with more toxic waste in heavy metals like cadmium than the nuclear power plant produced.

No solution is perfect.

But contrary to the propaganda, nuclear is one of our cleanest options.

Google isn’t the only tech giant that needs smashing into pieces, Microsoft, Amazon, Adobe, all need to be broken up. The tech industry shouldn’t be dominated by a few companies.

Oh please.

The evidence for Szabo is circumstantial at best. I’ll give you he has the skills and experience and was working on digital currency at the time.

But Szabo was just one of hundreds of people working on different ideas related to digital currency around the time Bitcoin was released.

And how many hundreds of people developed their own cryptocurrency after getting the idea from the Bitcoin whitepaper? Clearly he not the only “person on earth who had both the skills and experience”.

Not to mention Szabo has repeatedly denied being Satoshi.

They’re was never any evidence of google’s wrongdoing, the accusation came from former MS edge developers:

Officially Google denied it:

https://www.theverge.com/2018/12/19/18148736/google-youtube-microsoft-edge-intern-claims

You may be right, this could have been MS couldn’t make a better browser and pulled the plug, and the devs just blamed google.

I’m not defending Microsoft… but if we’re going to go after a tech company for leveraging their other assets to give themselves an unfair advantage can we also go after Google?

In the first releases of Edge, Microsoft tried to build a new web browser from scratch to compete with Google Chrome. By google kept changing YouTube’s code so that videos would playback janky on Edge. Microsoft eventually gave up trying to fix for YouTubes ongoing changes and now Edge is based on Chromium (the same open source web browser maintained by Google, that chrome os built on). Google leveraged YouTube to prevent completion from Edge.

And now Google is blocking ad blocking extensions so that users are forced to see more google ads in their browser.

Microsoft’s has leveraged their unfair advantage to get a little over 5% market share.

Google’s leveraged their unfair advantage to get 66% of the market.

Both companies need a hard smack down, but I want to see Google taken down too.

Just beware, sometimes the AI suggestions are scary good, some times they’re batshit crazy.

Just because AI suggests it, doesn’t mean it’s something you should use or learn from.

They call it jailbreak because this is an issue of freedom

I support your position and the right to repair, but that’s not the origin of the term jailbreak in the context of computing.

The term jailbreaking predates its modern understanding relating to smartphones, and dates back to the introduction of “protected modes” in early 80s CPU designs such as the intel 80286.

With the introduction of protected mode it became possible for programs to run in isolated memory spaces where they are unable to impact other programs running on the same CPU. These programs were said to be running “in a jail” that limited their access to the rest of the computer. A software exploit that allowed a program running inside the “jail” to gain root access / run code outside of protected mode was a “jailbreak”.

The first “jailbreak” for iOS allowed users to run software applications outside of protected modes and instead run in the kernel.

But as is common for the English language, jailbreak became to be synonymous with freedom from manufacture imposed limits and now has this additional definition.

It is, but lead based chemistries tend to wear out and need replacing a lot sooner than lithium ion.

You’re core idea is correct though, there’s a lot of battery techs that are cheaper / better when size and weight are irrelevant.

Whoever wrote that article is playing fast and loose with the definition of exponential.

Here’s the actual data of global electricity source on a log scale for the past ~15 years

Notice that the line for both wind and solar is inflecting to the right. If it was exponential it would be straight.

The time between each doubling of output is increasing.

It’s close, but not enough to be exponential growth.

It was exponential for a while but it’s slowing down in the last decade or two.

It’s not an exponential curve. It’s slower than that.

It’s more than linear; we are adding more capacity each year than the year before. But added capacity per year as a percentage of the previous years total is a decreasing.

If it was exponential the growth would be a straight(ish) line when plotted on a logarithmic scale… it’s not. On a log scale the line inflects.

Such an incredibly misleading article.

1 GW of nuclear capacity generates several times more electricity than 1 GW of PV capacity.

Nuclear power plants run at almost full capacity pretty much 24/7/365. With the occasional shutdown every few years for maintenance and to replace the fuel rods.

PVs only generate electricity during the day, and only hit their maximum capacity under ideal conditions. The average output of PVs is 15-25% of their capacity.

Globally we generate more electricity from nuclear than we do from all PVs together.

At the typical sizes we’re building them you need dozens of PV farms to match the energy output of a single nuclear reactor.

Tesla’s biggest issue is Musk.

Tesla held a commanding lead over the other automakers in the self-driving segment a few years ago. Now they’ve all mostly caught up thanks to Musk’s unhinged firings. Tesla lost some of its best talent for no other reason than not wanting to work for an egomaniacal billionaire nut job.

Tesla needs to fire Musk before he runs it into the ground just like he’s done to Twitter.

Genuinely curious, what new features did that updated firmware have that were valuable to you?

“Green Hydrogen” is made by using electricity to split water into hydrogen and oxygen. There’re no carbon emissions in that process, but to be truly “green” the electricity must come from a carbon free source like wind, solar, nuclear, or hydroelectric.

The process of electricity to hydrogen to compressed hydrogen to fuel cell to electricity is about half as energy efficient as electricity to li ion battery to electricity. As a form of electricity storage green hydrogen is significantly less efficient than batteries.

Green hydrogen only makes sense as a fuel in situations where batteries are not feasible.

And right now making green hydrogen at all does not make sense because if you build a new low carbon source of electricity it will make a larger impact if you use it to displace fossil fuel based electricity generation rather than using it to create green hydrogen.

Don’t worry he wasn’t lying to you, he was just presenting alternative facts .

Your math checks out.

Charging a 600 mi battery in 9 minutes would require a charging station that can output somewhere north of 1.2 MW.

We need major upgrades to the electrical grid as well as doubling our electricity generation capacity for charging stations and vehicles like that to be common place.

This is the trolley problem.

The trolley problem is a series of thought experiments that should be morally equivalent. In all variations, the reader can choose to take an action that will directly result in the death of an innocent person who was otherwise ‘safe’, or do nothing and allow a larger group of people to die, and ask what is the morally correct choice.

There’s no right answer to the trolley problem. The interesting take away is that what most people agree is the morally correct answer depends how the problem is framed.

When the situation is framed as “you’re deciding between one person dying and many people dying” most people will agree the morally correct choice is the one where the fewest people die.

But when the situation is framed as “are you justified in murdering an innocent person to save many” most people agree the morally correct answer is no.

There’s even one variation where is is considered by most morally correct to murder one person to save many, if the person you’re murdering is responsible for putting the larger group in harms way in the first place.
