Conservatives consume tons of porn. They just feel guilt about it afterwards.

frezik ,

Headline is terrible. The big red flags are that they don't do end-to-end encryption by default, the servers are in Dubai, and use a proprietary algorithm.

Last part should be clarified further. They didn't reinvent AES or anything. It's more like a protocol that puts together existing algorithms. It means they can use transport layers without TLS or anything else that wraps your messages in crypto otherwise.

I'd still say this is a red flag. How you wrap encryption around your messages has several pits you can fall into. It's not as bad as reinventing AES, though.

They are dirt cheap, don't have the fire safety issues as some lithium chemistries (not all lithium chemistries do that), and sodium is abundant.

frezik ,

While you're not wrong, sodium batteries coming on the market have 200 Wh/kg. This is comparable to where LFP batteries were a few years ago. That means the newer sodium batteries are about as good as what's in lots of EVs right now.

frezik ,

The other side of that is matching supply to demand is basically instant. You pull power from batteries and they give you more (provided they're not at their safe limit). There's always a lag in getting turbines to spin up and down, and so there's a non-trivial mismatch time.

frezik ,

Nuclear power should be expanded, a lot, it is the only realistic way to replace fossil plats for base demand.

This 90's talking point against Greenpeace is no longer valid. The economics have changed.

The newer sodium batteries are comparable to LFP batteries from a few years ago.

Oh, fuck a book, aahhhhhh

frezik ,

You don't have to pay to "prove" I'm right. You just have to accept that experts have looked at this, and nuclear does not need to be part of the conversation. Not beyond keeping whatever we have already, at least.

frezik ,

I am absolutely certain that experts have looked at it, and come to different conclusions.

I’ll even go as far as to accept that there is no scientific consensus.

And what reference do you have for that? A recent one, because as I said, the economics have totally changed in the last 30 years.

Nuclear power doesn’t really produce co2

Concrete does. Reactors need a lot of concrete. A lot.

Renewables are still not ready to deal with base load in a power grid long term

Which doesn't matter. Base load exists because it's cheap to make power plants that stay at the same level all the time. The economics of that don't apply to renewables.

Nothing, nuclear power will buy us time

Utterly untrue. It'll take 10 years to deploy a single new GW of nuclear. That's not buying time.

frezik ,

Lithium batteries are often -30 to 80C, but that's just saying what's possible to squeeze some kind of voltage out of them. Basic principle is that the colder it is, the harder it is for chemical reactions to happen, and thus this will affect all chemical batteries to some degree.

frezik ,

The Clone Wars movie also had a bar where the band was playing a bit schmaltzy. Schmaltzy Jizz.

Do they have to have their asses in the air like that? Does the sun god want to be mooned?

"Pawns can only move one space, except for their first move, when they can move two" - Statement by the utterly deranged.

frezik ,

Since leftists tend to also condemn those things, as well, what the hell are you on about?

frezik ,

Because we know from long experience that these questions aren't made in good faith.

frezik ,

A bunch of Marxist-Leninist governments turned out to be authoritarian, as well as fermenting cult-like behavior in smaller ML groups. That's a reason to drop that whole branch. Has nothing to do with leftism in the broad view.

frezik ,

If I didn't know it before, I do know it after you posted this little rant.

frezik , (edited )

They exist, but they're crude. Indoor farms tend to be labor intensive, meaning they have a lot of incentive to automate, but nobody has a really good system yet.

Knowing when a tomato is ripe and how to pick it off the plant is one of the better uses for AI image recognition and robotics, IMO.

frezik ,

Commercially pressed discs don't last forever, but longer than burnable discs. IIRC, they used to say 50 years for CDs, but in practice, it was a lot less. More like 20 or 30 if you store and handle them nicely. Easily less than 10 if you don't.

Hard drives go bad over time; I don't like trusting spinning platters much over 7 years. They can be OK, but they can suddenly stop working whenever.

SSDs are about the same as spinning platters.

frezik , (edited )

I upgraded my datahoarding server to a pair of 18TB hard drives on ZFS with mirroring a little while back. It'll be several years before I need to upgrade again, but I expect that when I do, SSDs will be cheap enough to go that route.

Already have a 10Gbps fiber connection to that server, so the hard drives are the bottleneck.

frezik , (edited )

- as opposed to +

WELCOME TO THE RABBIT HOLE

frezik ,

I wouldn't trust it that way, no. They might last decades. They also might not. It's a gamble on any single drive, or even a few mirrored drives.

File system also matters. Modern ZFS has error checking that can handle some level of bit rot. Older formats generally don't.

If it's over 7 years or so, I want to get the data off of there.

frezik , (edited )

Magnetic platters absolutely do break down from sitting around. Bearings and other mechanics can also go bad. For those things, a professional recovery operation could still get the data if you're willing to pay, but the drive itself should be thrown out.

Edit: keep in mind that with bit rot, the drive may superficially function just fine. Your data may even be 99% correct. That 1%, however, could cause unrecoverable problems, such as videos that glitch in the middle.

frezik ,

You keep doing this thing where you presume I don’t know about some issue

Maybe because you way overestimate the reliability of old drives. Yes, 10 year old drives can work. Doesn't mean you should trust them with anything other than getting the data off of it.

Most of the really out there Christian fundamentalists, the ones eating the brain of the US political system, are derived from the Protestant Reformation (or Anglican, which is sorta to the side of the Reformation). Even the more fundamentalist Catholics in the US have opinions that align to the Protestants around them rather than the Pope. Big Bang and evolution, for example.

Except we have better options than we did 10 years ago.

I'd be all for nuclear if we rolled back the clock to 2010 or so. As it stands, solar/wind/storage/hvdc lines can do the job. The situation moved and my opinion moved.

frezik ,

But the technology to rely entirely on renewables isn't really there either.

Yes, it is.

https://books.google.com/books/about/No_Miracles_Needed.html?id=aVKmEAAAQBAJ&source=kp_book_description

This is a book by a professor of Civil and Environmental Engineering that goes into the details. We don't need nuclear. All the tech is there.

frezik ,

No, you just pay out the nose up front.

If I had money to invest in the energy sector, I don't know why I should pick nuclear. It's going to double its budget and take 10 years before I see a dime of return. Possibly none if it can't secure funding for the budget overrun, as all my initial investment will be spent.

A solar or wind farm will take 6-12 months and likely come in at or close to its budget. Why the hell would I choose nuclear?

frezik ,

If you're going to do that, then also consider the co2 output of all the concrete needed for nuclear power plants.

frezik ,

... it's currently not possible to store the renewables anywhere

Every time someone argues this, it's immediately obvious they haven't actually paid attention how the storage market has been progressing.

Next, you'll probably talk about problems with lithium, as if it's the only storage technology.

frezik ,

Then we just move the problem. Why should we do something that's going to take longer and use more labor? Especially skilled labor.

Money is an imperfect proxy for the underlying resources in many ways, but it about lines up in this case. To force the issue, there would have to be a compelling reason beyond straight money.

That reason ain't getting to 100% clean energy in a short time. There is another: building plants to use up existing waste rather than burying it.

frezik ,

Nuclear is nothing bog standard. If it was, it wouldn't take 10 years. Almost every plant is a boutique job that requires lots of specialists. The Westinghouse AP1000 reactor design was meant to get around this. It didn't.

The experts can stay where they are: maintaining existing nuclear power.

Renewables don't take much skilled labor at all. It's putting solar panels on racks in a field, or hoisting wind blades up a tower (crane operation is a specialty, but not on the level of nuclear engineering).

frezik ,

And 5 years is what nuclear projects have promised at the start over the years. Everyone involved knows this is a gross lie.

frezik ,

China built a few Ap1000 designs. The Sanmen station started in 2009 with completion expected in 2014 (2015 for the second unit). It went into 2019. The second, Haiyang, went about the same.

This is pretty similar to what happened in the US with Volgte.

frezik ,

The problem Marx didn't foresee is that capitalism can sustain itself until it destroys us all. In Nazi Germany, this left the country a bombed out pile of rubble. In modern times, it's global warming.

frezik ,

If capitalism worked, then those workers would be a flood of cheap labor that could be used to build cheap housing (among other things).

frezik ,

Gmail and other big providers tend to consider new domains to be spam until they've proven otherwise. Can't prove otherwise until you've been up and running for a while. Catch-22. The way out of that is to host with an existing provider for a few years.

Does it cut down on spam? Perhaps. Does it favor existing providers like Gmail? Yes, definitely.

Honestly, hosting email has long been difficult to setup, and all the more so if you don't want your box to be a spam host within three seconds of plugging it in.

frezik ,

You know who is most fed up with YouTube's policies? Content creators on YouTube. They're locked in, they know it, and they hate it.

Good chance you could at this point.

OneDrive automatically backups folders in Windows 11 without users' permissions (windowsreport.com)

According to the latest reports, Windows 11 has made an independent choice by automatically turning on OneDrive folder backup for Desktop, Pictures, Documents, Music, and Video folders without your permission. This signifies that, whether you approve or not, everything is becoming coordinated with the cloud....

frezik ,

Vote this up higher. I wouldn't be surprised at all if everything ends up in their models.

frezik ,

Coincidentally, they make it harder to use a local account with every update.

frezik ,

Not how that should work. They don't get permission to all that unless I say so.

frezik ,

I wonder about Microsoft's liability on this one. People store all sorts of things in there, some personal, and some corporate things that are at least non-public, if not outright sensitive. Yeah, people should be using an encrypted drive for especially sensitive info (not that this would stop Microsoft when they own the OS), but they don't, and it's not for Microsoft to force the issue.

Did their legal department actually sign off on this? Or did someone in MS legal just shit a brick when they saw the headlines?

frezik ,

Hydrogen is probably going to get pushed out of every niche where it might be viable. Batteries tend to get better by 5-8% per year, and there's every reason to believe that will continue to be the case. Run that forward for another decade or so, and even things like heavy construction equipment and transpacific airplanes are viable on battery power.

It's a waste of time and money at this point.

frezik ,

Battery management electronics don't let you drain lithium batteries to 0%. It's a severe design flaw if it does.
