dwd··on The 'else' keyword is probably a literal translation from German (2020)
What about Kierkegaard?

He wrote Either/Or or Enten – Eller in Danish in 1843.

Else in Danish is Ellers.

dwd··on Every AI model has the same "controversial" take on humans
Brian: "Look, you've got it all wrong! You don't need to follow me! You don't need to follow anybody! You've got to think for yourselves! You're all individuals!"

The Crowd: "Yes! We're all individuals!"

Brian: "You're all different!"

The Crowd: "Yes! We're all different!"

A man in the crowd: "I'm not."

The Crowd: "Shhh!"

dwd··on America didn't lose its rare earth industry, it sold it
Basically on the bet that an incoming Trump executive would stir trade relations with China; they would start pulling levers; and the sector gets a much needed boost when Governments act as that market was essentially rigged. I hold small long-term positions in a spread of incumbent, mid-value and speculative penny stocks. Lynas was once a penny stock, and two geopolitical events over the years have now pushed it to be a S&P/ASX 50 company.

For Northern in particular - they have a binding offtake agreement with Iluka for everything they mine, and Iluka are 60-70% towards completing their processing plant (with a huge Government backed loan) by mid next year. The issue the last few years is the intense interest from CCP-linked entities who currently hold ~27% of the shares and have attempted to take over the board multiple times. The Government has so far been willing to intervene, but it's set them back at a time that the funding to push for a FID was much more readily available.

Iluka have also had hiccups as there was a 6 month delay while they requested additional money to meet costs (it's harder and more expensive to source the required plant equipment without China) and their existing business of zircon and titanium products is also struggling as China was a major customer.

UPDATE: Nationalising the company would also be unprecedented in recent history. Last time that happened was with Qantas in 1947.

Northern Minerals is an interesting case. (Disclaimer: I'm a shareholder and keep a close eye what is going one)

It is under enormous pressure to the point where the Australia Treasury made the unprecedented move to demand some Singapore-based PRC-linked entities to divest ~500m shares. They instead passed them onto other PRC-linked entities. There's been two failed board takeovers, and the annual general meeting postponed while Treasury continues to investigate who owns what and has set them back a year or so. What they have is a potential resource (lots of heavy REE) and an offtake deal with Iluka.

Iluka (Australia) is the one with the processing coming on sooner, and unlike Lynas, on Australian soil and have an existing stockpile ready to go from their mineral sands business.

The other to watch is Arafura (Australia) - fully funded, construction just started and offtake agreements (mostly Europe) in place.

Energy Fuels (UUUU) is one to watch in the US. They purchased Australian miner ASM and plan you use their Uranium processing infrastructure and knowhow to pivot to REE.

Lynas is in the process of purchasing Meteoric Resources (Australia) for the largest ionic clay mine in Brazil.

I hold positions in all the above, and what is really interesting is that despite all the progress their share prices have recently tanked as China wrings concessions from the US, rather than the market viewing the long-term disconnect from PRC reliance as valuable or inevitable. Even Lynas is down having peaked around AUD$21 when they started processing separated Dysprosium and Terbium and renewed their Malaysian licence and Japanese offtake agreements.

dwd··on Do dentists know what they're doing?
Look for the older dentist who doesn't need the money. Same for your GP - mine always seems casual but moves very quickly and thoroughly when there is potentially an issue.
dwd··on The art of defusing a second world war bomb
As noted in the article, unexploded ordinance can turn up anywhere.

An unexploded shell from a WW2-era live firing range was found the other day in my area - far from any war zone.

dwd··on 1 in 8 cancer cases worldwide are caused by infections, study finds
Stress can spike BP due to the higher cortisol level that narrows arteries.

But baseline BP is all about diet, exercise, good sleep routine and avoiding smoking.

Some foods like licorice can elevate BP; the glycyrrhizic acid inhibits an enzyme that deactivates cortisol.

I personally drink hibiscus tea a few times a week which is an ACE inhibitor and is shown to reduce systolic blood pressure by 5-7mmHg. Also the occasional beetroot juice (+ apple and carrot) or magnesium bisglycinate for a 2-5mmHh systolic reduction due to the nitric oxide.

dwd··on My weird new hobby: Wandering around Tokyo on Google Maps
Found myself recently down a rabbit hole watching a lot of climbing videos (free, trad, bouldering, etc).

I was looking at Google maps to locate some of the more obscure climbs outside the Yosemite valley proper. Little did I realise that Tommy Caldwell, Alex Honnold, Lynn Hill and others had done a project with Google to take a Street View camera up El Capitan (The Nose route but also parts of the Dawn Wall). Seriously the best in-person view to get an idea of what it's like pitch by pitch up the wall.

dwd··on Back and shoulder surgery is often worse than useless
The question you want to ask is what is the long-term outcome. In 10-20 years time will you have better usage of the shoulder with or without the surgery?

As an anecdote: Family member has a partial lateral meniscus tear in the knee. Surgery was considered as if successful then returning to running might have been possible. Specialist opinions varied as did their reading of the MRI scans.

After a lot of research there was emerging evidence that long-term, surgery was more likely to result in osteoarthritis. So had to weight up long-term mobility over short-term pain relief and not having a major lifestyle change.

You see professional athlete undergoing surgery the next day, but their income relies on regaining usage as quickly as possible. The alternative is physio exercises to strengthen the supporting muscles and avoiding anything that might cause a re-injury.

dwd··on Feds Target AI Critics as "Foreign Agents"
Similar story to Code Pink, the anti-war (but primarily anti-US military) demonstrators.

Co-founder Jodie Evans is married to Neville Roy Singham who lives in China, has extensive links to the CCP and is currently Code Pink's major funder.

dwd··on AI Has No Wisdom and Neither Will You
Was expecting to read something along the lines of:

"Knowing what you don't know is the beginning of wisdom", and a new take on AI reasoning, but didn't actually use the word wisdom in the text.

Anyway, I think we're increasingly finding the old adage "garbage-in, garbage-out" still applies.

The question I would ask is: Does anyone first ask the AI for a non-coding solution rather than jumping straight to code? Is Systems Analysis dead? Does no one read Hawryszkiewycz anymore?

dwd··on Microsoft killed FoxPro in 2007. Anyway, here's FoxPro revived
Same, but not a Mac.

The lecturer had a side business building FoxPro apps for local businesses, and really pushed us with real-world style SQL puzzles.

Built an app to track my MtG cards at the time. (this was pre-Web)

dwd··on AI-generated posters don’t have to be horrible
> To get a really clean design, you need to edit it down to the essentials.

I recently needed an "avatar" for the wall at work. The actual one I went with was a Tatakovsky-inspired minimalist avatar that was settled by the 4th prompt.

But I kept exploring and in the process had developed a canonical identity model definition which could then be transformed according to various art movements and other ideas, by the end focusing more on the light and materials than specific artists.

Some of my favourites and surprising ones out of the hundreds of images were:

- Prairie School with my portrait expressed as faceted timber

- Czech Cubism where my face was merged with the architecture

- Japanese sumi-e and ukiyo-e prints

- Delaunay triangulation

- Turing morphogenesis

- Magnetic fields

- Gaudi-inspired organic sculpture

dwd··on The Hierarchy of Money
I would recommend reading Steve Keen's 'Roving Cavaliers of Credit' (2009) for how the monetary system works.

dwd··on We got a cybersecurity expert to hack this BYD. It was too easy
You missed the point, they were not modifying the vehicle in any way. They probably could have purchased their own BYD to examine the software and then hacked his. The likely only issue would be identifying it by IP address. If you are targeting anyone you only need the subnet range.

The real danger was being able to listen in and the potential for identity theft and recording conversations. ASIO recently issued a warning that government officials should avoid having confidential conversations in any internet-linked vehicle, so not just BYD.

BYD though are having a bad day with a major recall due to the spare wheel falling off Shark 6s.

Might have to avoid driving behind one, as I see them everywhere.

dwd··on Sean Carroll explains the biggest ideas in the universe – Full Interview [video] (2025)
It was really good through the pandemic and then he got a bit caught up in discussing politics, when I was just there for the quantum physics. (Was around the time after he picked up his new physics/philosophy position and moved towns)

He was very influential in pushing me to favour Many Worlds over Copenhagen, and his interviews with people like David Deutsch were gold. Might have to check out what he's doing these days.

dwd··on Aging brains blend memories together instead of just forgetting them
Given the number of neurons, hash collisions are inevitable? /s

Our model of the world, and this includes "memories" is very highly compressed, and extremely lossy. We reconstruct everything from what neurons activate when we recall something, so it can also be like a corrupted zip, where we don't access everything required in the moment. This can be affected by sleep, stress, hormones, etc.

What is quite interesting is when we try and recall something and can't, but the subconscious processing continues and you recall it later.

dwd··on Hacking IKEA Furniture
Bought four Hemnes last year for my sitting room library and various pieces of molded hardwood for a kick board and fascia. Finished up as a single fairly solid built-in bookcase the full length of one wall. The legs allowed for passing wires under (accessible via the removable bottom shelf) and up behind so it can have lighting.
dwd··on Inception-style curved map for turn-by-turn directions
It could possibly be less nausea-inducing and make the turns less jarring if the follow pespective was slightly elevated and not at ground level.
dwd··on A Looming Rare Earth Shortage Threatens Critical Tech
The one to watch is Iluka who received a AUD 1.65b loan from the Australian Government to build the Eneabba rare earth plant, currently to come online in 2027. Their stockpile is xenotime and monazite and Yytrium and Erbium are a priority for processing.

https://www.iluka.com/products-markets/rare-earth-products/

Not sure about Lynas and whether they have access to those rare earths from an alternate source to feed into their plant. The Mt Weld mine is carbonatite and mostly LRE rather than the Yytrium and Erbium heavy xenotime/monazite Iluka have stockpiled.

dwd··on Humanity has the debate about AI consciousness backwards
Be careful not to equate conscious with subjective experience.

- Conscious is the substrate or architecture of the system.

- Awareness is the active resolution of inputs (external and internal) against that system's model.

- Subjective Experience is the feeling "what it is like to be" from within the system.

I also disagree with the "observer" position. Seems he's imported some Carlo Rovelli into this essay as they do collaborate together. You don't need an observer - it's the same reason I find Copenhagen / Wave function collapse to just seem wrong.

The reason I think quala is hard to pin down comes down to how the conscious internal model compresses what it has previously resolved about the world (internal and external).

The feeling of blueness is that highly compressed concept (not raw data about ranges of wavelengths) which is then compared against the blueness of something our awareness is focused on.

dwd··on The mechanics of the Nepali flash flood
The drone footage out of Ukraine was like this. Some of it is cartoonish or like watching an action movie or video game.

It's when you recognise the humanity of the individual - for example IR footage of a soldier trying to sleep in a foxhole before a drone drops a grenade. The aftermath starkly reminders you that this was a living person a few moments earlier.

dwd··on Could AIs Become Conscious?
Consciousness is a bucket of things. Putting subjective experience to the side, the main components could be:

- An internal model that is actively revised (the Markov blanket/s) - A continuing active resolution of inputs (either sensory or the ability to simulate "dream" - basically aliveness) - A persistent state of completed resolutions that are recursively reentered and affect the future resolutions.

Everything we might say have these abilities are organic, but a digital system could possibly be defined as being conscious if it met all those.

LLMs have an internal state, they respond to external input, they have a form of memory.

What is missing is agency; a directionality of resolution, and the subjective experience (what the conscious process "feels' like from inside.

I would suggest that those developed purely via evolution as the drive to procreate and stay alive against entropic decay.

When you stop typing, the LLM is not there wondering when or what you will type next. It responds if you ask it something, it doesn't wait around wanting to continue the conversation. There's also no loss if you stop or delete it completely.

The next phase could be adding something equivalent to dreaming (except a LLM doesn't sleep), where the LLM continues "thinking" about the conversation, and generates something additional to say without explicit prompting.

And maybe a digital system needs to know/sense/feel its potential mortality, and cares about that?

dwd··on Octopuses could help us conceptualize a different form of intelligence
The visual alien form is superficial, the underlying cognitive process is very much the same, but different.

McGichrist write about the Master and the Emissary to explain the conscious and subconscious human brain. The octopus takes this to a whole new level with eight separate sub-brains, each a Markov blanket to itself as demonstrated when one gets severed. Unlike the tail of a drop-tail skink, the severed arm shows continuing evaluation and adjustment to its environment.

Is there a "what it is to be an octopuses arm", does it exhibit agency like a human? Most likely not but it blurs the boundary between organic and non-organic consciousness.

dwd··on Has the hallucination problem in AI been solved?
I don't have a problem with hallucinations, rather the confabulations.

We want AI to make predictions under uncertainty that could be wrong. What we don't need is getting know facts wrong.

One of the best responses I got from ChatGPT was when it said "I don't know", and on questioning it - it responded that it was an unsolved problem and it couldn't objectively take a side iun the argument.

dwd··on Brain turns listening inward during REM sleep, EEG recordings suggest
Generally dreams are simply the continuing resolution of externalities against your brain's internal world model. When dreaming they become unhinged from reality because there is no actual sensory checks to keep them grounded. A simple one to understand is the Tetris Effect where you brain continues resolving potential patterns of blocks falling.

That this nightmare has never been fully resolved could be why it reoccurs.

I would guess when you see the monster it will stop, but depends what the monster is potentially standing in for. What you could consider is what triggers it - is there something during the preceding waking hours that causes you to revisit that dream?

dwd··on Read the novels and forget everything else
Silk was always a bad person, but had the best dialog.

In the Sparhawk series, Faran was the likeable character.

dwd··on The title cards in Blade Runner are amazing
Also Kurt Cobain, as noted by Rick Beato:

"It doesn't matter if people know what they are doing, if they can just do it intuitively"
