Only a small fraction of Uranium is usable for fission without breeding. There is (IIRC from a LFTR youtube) 4-10x as much thorium as uranium.

The other issue is most designs are solid fuel rod, and they waste a huge percentage of the fuel once "spent".

Nuclear isn't price competitive with existing wind/solar, and any new nuclear project is 10-20 years away, and with wind/solar in substantial/active cost improvement and economies of scale, nuclear may never be competitive.

I loved those LFTR presentations, and I would like to think a scalable LFTR solution could be made price competitive with wind/solar once it stabilizes, but right now probably not.

LFTR can use thorium (still needs a fissile uranium starter plug), and can probably breed non-fissile uranium, I've heard it can breed existing nuclear waste into usable fuel as well. It uses 99% of the fuel according to the sales brochure, which I view as a massive huge advantage: it takes all the handwringing and NIMBY about waste storage out of the equation. IMO that should be a table stakes for any "new nuclear" design.

It's basically meltdown proof with the plug, isn't pressurized, and somewaht self-regulating in temperature if I understand the neutron economy and expansion/contraction of salts. Also a "table stakes" aspect of any new nuclear project IMO.

Scalability is probably the biggest path forward to competitive fission as well, the original MSR at ORNL was allegedly closet-sized. Massive concrete dome designs lend too much to boondoggle management and cost overruns. Scalability would enable nuclear to compete with the current kings of scalable power generation: wind and especially solar.

Maybe pebble bed can get a lot of the same table stakes as LFTR. Maybe a LFTR could serve as an onsite fuel reprocessor for a more economical design if LFTR isn't broad market feasible. I'm not a nuclear engineer, I'm just a fan of the ultracool engineering and science.

But the economics don't line up for nuclear currently.
Unless you're drinking like 6 a day it's nothing compared to regular coffee drinkers:

12oz coke zero: 34mg caffeine

12oz brewed coffee: 120-240mg depending on beans and strength

Double shot espresso: 60-180mg

I can easily do 2 12oz brewed or doubles in a day and friends drink much more.
Gruber isn't always right, but he's right here. I use Macs and Thinkpads for work. My M1 Mac is by far the fastest and also has by far the best battery life and uses the fans the least often. x86 is way behind ARM right now.

You really can't get to a good understanding on this issue without an analysis of comparative harm.

The issue is only partly about whether non-sugar sweeteners have negative effects. The more important question is whether regular & processed sugars produce an overall worse impact than substitutes consumed at comparable levels, with stratification by consumption level.

E.g., non-sugar sweeteners may have a similar danger profile at both low and high levels of consumption while sugar's negative impacts may be more linear. Or so other balance. In a situation like that, the proper advice to individuals looking to become healthier may vary, especially given that immediate and rapid wholesale change if a person's behavior is not usually possible.
To be fair, the original author of the quoted article is probably doing most of the smoking of things. All Gruber did is restate it and add the obnoxious political snipe at the end.

Windows people, how much faster would a non-Windows machine have to be before you'd start to consider using something other than Windows? I know if the question were flipped and given to me as a Mac user, the answer would have to be something like "fast enough that the muscle memory and system knowledge I've gained from three decades of Mac use could be overcome by sheer system speed of the Windows machine," and that would have to be pretty damned fast. Given that it's pretty irrelevant to me to compare the two.
How is it fair to only compare raw salary numbers? There is nearly zero safety net in the U.S. Two weeks paid leave at best, you're expected to work long hours, healthcare is a mess... Compared to Western Europe, where there is affordable healthcare, saner labor practices etc.
There's a commercial bias at play with pretty much all review content, print or otherwise. I've been griping about this for years now. The major outlets and Youtubers all have relationships with various vendors in order to get early access to products so their reviews can coincide with the product launch.

This creates an inherent conflict of interest that has to shape their reviews in some form or another. The problem is that there's no transparency at all. They're talking with company reps before a product launches and signing embargo agreements to not release content early. I'm not saying that every piece of review content is low quality shill clickbait BS, but the reviewer has a relationship with a company and there's no way that doesn't influence their work given that early access is important for staying relevant in the space.
Hmm. I don't really get that. If document provenance matters, don't you want to keep it read only?

People always ask: "what about the waste?"

Nowadays we answer: "What about it?"

Air pollution and climate change are vastly more serious and challenging problems than the storage of high-level nuclear waste.

The first question is easy. No.

As far as should you abandon 2 years of credits to switch from a top ten school to the number one school…I just can’t imagine the benefit outweighing the cost. Starting your career 2 years earlier is probably going to be of more value.
> You can kinda guess with the numbers only, but many paid transport systems have had near perfect info on this their entire service lives. It would be weird to lose it.

This level of indiscriminate surveillance is absolutely abnormal from a historical perspective -- it's "weird" they have it in the first place! There's no reason to think that it's necessary. (And since most public transport systems are at least partially government run, and your travel card is associated either implicitly or explicitly with your real identity, travel cards have become an excellent way for the government to surveil every member of the public indiscriminately, allowing for retroactive surveillance -- though of course rubber-stamp courts would give them access to this information from private companies too.)

Most public transport systems have not had access to this information for the vast majority of their existence (and managed to botch expansions just as well as they can today with the benefit of all this data) and have only gained access (along with law enforcement) to it recently.

The issues with increasing public transport coverage is not a lack of data, it's a lack of funding and interest.
Every major AC producer makes variable speed systems. They are called "invertors" sometimes.
It may not be the oil industry, what's really going on right now is nuclear is making a comeback. The Renewable energy future may turn out have to be depending on it.

Mac enthusiasts just can't accept the fact that people prefer to buy Windows machines over Macs by a wide margin. I used to be one of them, but the closed hardware approach and the "we know best" attitude turned me off long ago.

That said, if I needed a super fast machine to do graphics or video, I'd look seriously at the new chips. I don't need such a machine.
Not the offer, but the signed contract. Before that it's just like a quote on work you need done. It has no binding.

Punchline:

> My tarball happened to contain over 800 000 links with ".." as a path component. It also happened to contain over 5.4 million hard links.

The behavior is more precisely described not as quadratic, but O(n*m), where n is the number of symlinks pointing outside of the extraction directory, and m is the number of hardlinks. It happens because of the security precautions gnu tar performs to make sure a malicious archive can't set up a symlink pointing to an arbitrary place in your filesystem, and then extract files to it. The strategy they use has an unoptimized corner case when the archive also has a lot of hardlinks.

The mechanism could probably be improved by remembering the list of deferred symlinks in a hash map rather than a linked list, but also, both symlinks pointing outside the extraction directory, and hardlinks, are uncommon.

(Edited to correct: The problem exists even if the hardlinks do not actually point at the symlinks.)
If you've got arm64 images, it works great. If you have x86_64 images, it probably still works, but it's not a guarantee - we definitely have images at my workplace which do not work emulated - and it's substantially slower than on an x86 machine. On top of it being slower anyway, since Docker for Mac is running the daemon in a VM.

I'm really happy the M1/M2 exists, and I have access to an M1 MBP, but I'd still rather have a nice Linux laptop. Especially for containers.

Edit: One severe (to me) incompatibility I ran into with the M1 MBP is that it would not run my dual monitors (dell, displayport) through either of the TB3 docks (belkin, caldigit) I had available. I ended up replacing the monitors. Worked fine with the x86 MBP.
Fossil + biofuel makes 80% of our energy today. Getting rid of that will require vast amounts of zero-carbon energy. Wind and solar need to be built out at breakneck speed if we want to be serious. Much faster than what we're doing now. So does nuclear fission.

I assume you're only looking at the slow and expensive nuclear builds?

China is looking to build 150 new reactors to meet its goals.

https://www.bloomberg.com/news/videos/2021-11-03/china-is-pl...

We also have ways of making nuclear reactors extremely quickly if we want to get really serious. In the 1970s we started building a facility in Jacksonville Fl capable of delivering 4 large LWRs per year in a shipyard-like factory. The reactors were to be floated off to their sites (the first of which were offshore). They installed the world's largest gantry crane at the facility. Sadly the oil shocks reduced the energy demand where their first customers were (New Jersey refineries) and the effort failed after they received a construction license from the nuclear regulatory commission. Building zero carbon power plant gigafactories like this can solve climate change, you betcha.

> If you manage to get a couple of tenths of a percent performance increase in one of the big compilers during your career, you will have materially impacted global warming.

I've heard this kind of claim a number of times and I think it's more complicated than the crude statistical measurement makes it sound. Personally, I think that most programs are not run frequently enough to matter from an emissions perspective. For programs that are, like ML training programs, users will just train more data if the algorithms are faster so most energy efficiencies will get wiped out by the increased usage.

Even if that theory is wrong, what if there is a language that is 10% better than C for 95% of common C use cases? Wouldn't it be better for compiler engineers to focus on developing that language than micro-optimizing C?
> It's a $2,000 laptop running the same OS as a $900 laptop, running the same git binary that you execute on a $35 Raspberry Pi. I don't see it.

I suppose you're right if you do absolutely everything on the command line, but in terms of the GUI and GUI applications, there's a world of difference, and once you factor in the Apple ecosystem (so contacts and notes are automatically synched between my phone and my Macs, etc) and the speed and polish of programs like Safari and Numbers, the value proposition becomes quite different. Us Mac users could use our Mac systems as generic Unix/Linux boxes, but few of us actually do.
Personally I have both a surface studio laptop and a MBP. I find myself using the surface much more due to the touchscreen and pen input. It’s plenty fast and has great battery that lasts all day. Sure the MBP is really fast, but I mean, so what? So is the Surface. If I need to sign something on the MBP I still have to pull out an iPad, and I guess that’s the way Apple wants it.
Fascinating, I always thought there was more of it created rather then this little. I do like how they point out the only issues so far seem to be political rather then any real "hard" problems to solve.

Hopeful with more climate focus these we'll have more political will to take such easy actions.

Agreed. The excitement in fusion indicates a total failure of fission people to effectively explain what they are capable of.

I have a 14" M1 MBP from work. I've never purchased a Mac for personal use, but that's going to change when I can justify replacing my Thinkpad. They made an impressive machine while also taking away all of my hangups with the hardware (keyboard, ports, touchbar).
We lost several weeks for about 10 new devs at my company who started in May/June because Apple only sells M1 now, so that’s what the new devs got, but all the old devs have x86. Poetry+geospatial libs+other stuff didn’t work at all and the new devs struggled to fix it because while they may have had 5, 10, 20 years of software experience, they didn’t know all our stack and didn’t know M1. The remote environment made debugging very slow.

In retrospect we probably should have forced all devs to switch to M1 at once and upgraded everyone’s laptop, but we saw all these posts about how everything works on M1 and that just wasn’t the case at all in our experience.

Currently living in a rich area, 20 stories very modern high apartment complex. The first thing I thought when stepping into the apartment for the first time with its massive windows was “jikes the windows are leaking heat like crazy”.
In my old home that was 60 years old it had way better insulation (with triple layered windows).

What I’m trying to say is that this is about incentives, not about how old things are. The modern building let their tenants cover the AC cost while the old one had water heating instead included.

Except externalities are a thing.[1] Externalities are positive or negative impacts on society that do not accrue to those who cause them. Typically, rail transport leads to an increase in land prices and rents, but these additional profits are not recovered through fares, but fall into the hands of landowners. For this reason, railroads have historically been funded through land grants. For the same reason, most infrastructure is government-funded, such as airports, roads, or schools.

[1] https://en.wikipedia.org/wiki/Externality
It's the other way around: real numbers are imaginary. All numbers are imaginary. Numbers are very useful concepts, and can be used in various ways to describe parts of reality. These descriptions can stop making sense if inappropriate kinds of numbers are used (e.g. -5 makes perfect sense as a displacement, but not as a count, and 5i makes perfect sense as part of a description of simple harmonic motion, but not as a displacement).

The use of the word "imaginary" to describe parts of complex numbers is quite unfortunate [1], because it misleads people into thinking there's something fake or weird about them, leading to confusion and entire articles trying to convince people they're valid. They're a totally normal, expected, and widely used feature of number systems as we understand them today.

The name they've got comes from how surprising and foreign they seemed to the people who first encountered them. Irrational numbers were similarly surprising and foreign to the people who first encountered them. Today we're perfectly comfortable working with irrational numbers like π, but the original reaction lives on in other meanings of "rational" and "irrational": based reasoning, and not based on reasoning, respectively.

"Imaginary" seems like a tougher hurdle, and while the article says "imaginary numbers" many times, mathematicians and physicists don't really. We talk about complex numbers, and describe complex numbers with 0 real part as "pure imaginary". "Imaginary" and "real" are just labels for the axes of the complex plane, and neither is literal in this context.

[1] As is the word "complex", which most commonly now means "complicated", but is used here with another meaning: made up of multiple parts.
> but I suspect this goes back to how early binary computers used 36-bit words (later 18- or 12-bit ones)

Actually the PDP-1 was an 18 bit machine; its successor the PDP-6 had 36 bit words (and 18 bit addresses -- yes it was explicitly designed to be a Lisp machine in 1963). Other DEC machines like the PDP-7 (on which Unix was developed) were 18-bit machines (Multics used an 18-bit non-DEC architechture).

Probably the most popular minicomputer ever, the PDP-8, used 12 bits, as did a bunch of DEC industrial control machines.
That is only if you are ok sticking with the same specs on your machine for 5 years and risk using a machine outside of its warranty period.

You left out the fact that JK rejected the notion of a world teacher and disbanded that particular association. He also rejected theosophy as a whole, and any organization that claims to know any such thing as a “Truth”.

It’s interesting that he would reject the money and power that came with it just because he didn’t believe in it. Most godmen and “spiritual entrepreneurs” wouldn’t.
