> Is that enough to have an acceptable lifestyle?

I’m always baffled by this kind of comments. The world isn’t made of SV engineers making 300K$/year, living in appartment with 5K appartment and buying 40$ sandwiches. Sure, most places and jobs are paying less, but cost of living is also lower. In Japan for instance eating out is cheap compared to Europe. Healthcare is accessible too. Cooking can help saving money too. Heck, I’m living (alone) fine with $16K/year (yes, per year) in one of the biggest Japanese city and I still can go to parties, buy video games, travel abroad while saving some money.

Per https://en.wikipedia.org/wiki/Zip2

> In Ashlee Vance's biography of Elon Musk, it is claimed that the Musks' father, Errol Musk, provided them with US$28,000 during this time,[4]:Ch.4 but Elon Musk later denied this.[6] He later clarified that his dad provided around 10% of US$200,000 as part of a later funding round.[7]

I feel like someone who is able to get 90% of their funding round could either convince an existing investor in the round or convince someone else to join the round. This doesn't sound like money to "start Zip2" as you claim.

Also, note that Elon had to shower at a YMCA while starting up Zip2 (https://www.cnbc.com/2018/06/19/how-elon-musk-founded-zip2-w...). Does that really sound like a "trust fund baby" to you? I feel like a lot of the myths trying to tear down Elon Musk's successes are all sourced from Ashlee Vance's book, which in turn are based on, as I understand it, interviews of Errol Musk himself (the father).
Ok, standard 4x4 matrices also implement a projective (aka d+1) model. (the 'w' coordinate is just the projective coordinate). So no difference with GA in that respect.

Setting up a unified transformation hierarchy is actually very easy, and again not really different from how you would approach it with matrices. (plus, its more performant). Simply swap the matrix with the appropriate versor.

Which (versors or matrices) are appropriate depends on the symmetry group you are interested in :

Orthogonal Group (just rotations : distance + origin preserving) in d dimensions -> use the geometric algebra R_d. (classically : complex numbers, quaternions)

Lorentz Group (rotations + boosts : spacetime distance + origin preserving) in d space dimensions and 1 time dimension -> use the geometric algebra R_{d,1}. (classically : Lorentz transformations)

Euclidean Group (translations + rotations : distance preserving) in d dimensions -> use the geometric algebra R_{d,0,1}. (classically : planar quaternions, dual quaternions)

Conformal Group (translations + rotations + dilations : angle preserving) -> use the geometric algebra R_{d+1,1}. (classically : linear fractional transformations)

General Linear Group (translations + rotations + sheering + ... : preserves parallelism/incidence) : use d+1 x d+1 matrices.

Working in a symmetry group that is 'to big' comes at a cost - both in algorithmic complexity as well as numerical precision. If you only want translations/rotations, but are using matrices you'll have to resort to things like Gramm-Shmidt or SVD to re-orthogonalize your matrices after doing numerical calculations. (you have to project it back to the solution manifold in math terms - this is almost never trivial and often impossible).

(for those interested, I explain this in-depth in my GAME2020 talk : https://www.youtube.com/watch?v=ichOiuBoBoQ&ab_channel=Bivec... )
I wonder if we could replace both taxes with a general carbon tax and just take infrastructure out of income and carbon tax combined. Decouple transport tax income from KMs driven entirely.
It is extremely competitive. Stress is indeed motivational , and it is part of what makes it fun. Once the difficulty starts to increase I can spend an insane amount of time on a simple task. I stay away from these competitions, simply because I don't have time to dig into the material and it makes me feel terrible when I have to abandon a task because of real life, or xyz.

I’m probably not supposed to be bothered by this

Why not? I'd argue it's better to be bothered by it than just exclaim "ok it's for science" without any critical view. Anyway: it's extremely common especially with mice. You'd be suprised by the total numbers (which might be hard to acquire having to sift through animal-rights but the order of magnitude should be correct; I'm guessing a couple of tens of millions rodents per year in the US is ballpark correct). A bunch of reasons like what a sibling commenter says but also because you can usually not use mice which were used for experiment A in experiment B exepcting A had no influence.

Er. Yes, but in SV for example:

- housing is literally 4x or 5x or even 10x the pricing elsewhere in the US.

Rent is easily in that category too.

- food, fuel for your car, electricity, and literally everything including haircuts is more expensive there.

Often, several times more expensive.

Pay = base needs + retirement savings + extra money for lifestyle/fun + bonus for skill set

If base needs + retirement needs + lifestyle/fun costs go up/down, then of course pay will go up/down.

Yes, 'skill set' remains static. Unless, of course, there is a surplus in one area (people not willing to move), and a shortage in another.

In that case, yup.. guess what! That commodity becomes more valuable.

I'm not sure why many people find all of the above confusing.

It’s not since you’ll still need to get people into the country and quite likely people with less field experience.

Not to mention that to pull anything like this off you already need to have an extensive network of assets in place.

There are plenty of local resources you’ll be able to use ranging from local opposition groups to hired criminals from Iran and the Caspian region heck getting some offshoot of the Syrian opposition to lend a hand after Iran helped Assad isn’t out of the realm of possibility either.

You assume this was some SEAL Team Six operation, the fact that as many as 12 people opened fire indicates it quite likely wasn’t and the assets who performed the assault itself were quite likely less trained and much more expendable.

These M1 Macs are more like iPads than Intel Macs. Jail breaking them would be the first step, but after that one would need a ton of reverse engineering to write all the drivers for all the little custom HW built into M1 SoC.

I have never heard of an iPad running Linux (and iPads been around for a long time), so chances of M1 running Linux natively is slim.

I'm not insulted. The concern is valid. Its range of application is just so fringe as to make this a near-academic discussion.

Yes.

No, they don't have to. While a usage fee model is one possible model, there's no reason it couldn't be paid out of general taxes, like the income taxes mentioned upthread.

> Institutional racism is "racism that is embedded as normal practice within society", which only occurs through the mechanism of systemic properties like its laws or rules, or its social contract, just as I explained.

Come on. You've cherry-picked a single vague line from the preamble of that article because it's so general that it also fits your narrow definition. The rest of the article goes on about the established definition.

You're redefining an entire concept coined to mean what we are talking about. Instead your clutching at straws adamantly sticking to the textboox definitions of the each word. That's just childish and have to place in any adult conversation.

Just in the last week you've redefined the following to fit your unsupported narrative here on HN and called everything else objectively false and refused to even discuss the other definition:

* Institutional/System racism, ignoring ~50 years of history (for the term itself, the practice itself is obviously much earlier).

* Soclal Democracy, ignoring ~200 years of history

* The concept of personal property and it's distinction from private property. Ignoring ~200 years of socialist history.

You do realize that you don't have to agree with the concept to at least discuss it? Something like "Yes, if we use established definition, which I disagree with, there's systemic/institutional racism against black people in America".

Because what definition do you even think people are using when asking you if it exists? "Do you like the color blue?", "No! there's no blue color". That's just childish and will never generate any constructive discussion at all, and is for all purposes just trolling or at least sabotage - answering a question that contains an established concept/definition with an entirely new one that only you know about.

Almost every era thinks they have achieved so much - prosperity, progress, knowledge, scientific temper but lost something ineffable - their happiness. Perhaps in our genes to forever feel cast out of the garden of eden and strive to get back there.

Happiness is an internal state without an objective measure. Worse we don't know what makes us happy. Too little wealth ==> unhappy. Too much wealth ==> unhappy (maybe) but don't see many giving it up.

I think I would be miserable without the internet, social media but I am happiest chopping vegetables and washing dishes. Maybe we all just need to go and wash some dishes.
Kolmogorov complexity is a useful concept in the abstract but since it's not computable I find it hard to see anywhere it can really be applied. It doesn't solve the impossible problem of somehow deciding the true information content of any piece of data, it only locks it away in a slightly neater box of impossible.

How much some data means depends completely on everything else you know about the world. You could imagine under different priors of knowledge, different strings would have differing kolmogorov complexity. not technically true, because kolmogorov complexity Is fixed, but that assumes you have the absolutely omniscient model for everything.

While not specifically related to Geometric Algebra, much of even simple vector algebra itself is usually taught and presented in a confusing manner, is what I think. Elementary questions like whether a vector has a start and end point, has it got an orientation along its own axis, is it possible to determine if two given vectors are in the same frame of reference, etc are simply not obvious from most treatments of vector algebra I have seen.

I do see a pressing need for a full treatment of the topic without notational or conceptual ambiguities. Atleast mathematics owes it to the other sciences that much, is what I feel.

I'm also guessing any plant with a substance that acts as a MAOI would probably potentiate the effects of lots of other substances. So my guess is that it may not have taken that long for at least one person (or maybe multiple people independently) to discover that this plant seemed to alter the effects of other plants.

Then at that point some adventurous people may have just started trying combining it with every other plant they knew about and every future one they discovered, including plants that they otherwise believed had no effect. They probably would've stumbled upon a lot of interesting combinations.

And if they determined it had a strange ability to seemingly "unlock" "dormant" plants and if they spread that knowledge, maybe some people were trying it with absolutely every non-poisonous plant out there. And since DMT-bearing plants are pretty common (as you mention), multiplied across a whole society it may not have taken very long at all. And it would take just one MAOI plant for them to get the idea that other plants might have this unlocking ability, and just one DMT-rich plant to discover other plants might have similar effects, so maybe they iterated through combinations of MAOIs and serotonergics until they found one they felt had a good balance of maximal power and minimal undesired side effects.

So the bottleneck might be the first instance of someone ever discovering any kind of MAOI plant (this vine or any other). After that barrier is passed, I suspect it might be almost inevitable that something like this particular combination would be found pretty quickly (just blindly speculating, but potentially within a generation or two?).
He asked that in the "aren’t you all living in the streets of Japan with so few money?" in a humble-bragging tone that is quite common here when speaking of wages in an international context.

Super Nintendo World Opens on February 4th with AR Mario Kart Rollercoaster
The price paid for labor is only tangentially related to the value of product produced. Wages are set by supply and demand, and the labor market is still very much location dependent. Companies who need local workers are forced to pay the rate required to attract and keep them, and that cost is a lot higher in some places than others.

The company doesn't pay someone in San Francisco more than someone in Kansas because the San Francisco worker has a higher cost of living, they do it because the San Francisco worker would go work for someone else for more money if they didn't. The worker in Kansas doesn't have that alternative option.

Now, as more and more companies become primarily remote employers, we will likely see the location based variance for workers diminish. However, this is likely to mean that the higher cost of living places see their wages decrease more than lower cost of living places increase.

TLDR: Biomedical scientists from Spain recently found that DMT (plant-derived drug in Ayahuasca) can massively improve memory and learning, through the birth of new neurons (i.e. neurogenesis).

From this research, it was wonderful to discover:

-Neurogenesis is an effective treatment for clinical depression

-Diseases like Alzheimer's and Dementia kill neurogenesis

Could DMT become like a coffee of the future?
Both the EV tax and the ICE fine for parking in EV slots were mentioned in the original article. They are separate policies that seem to be conflated in these comments.

The reason why they are implementing an EV tax partially based on miles driven is because EVs cause wear and tear on roads, but contribute little to none to those maintenance costs through petrol taxes. This is why plug in hybrids pay a lower tax rate in their policy (as presumably they'd pay at least some via the petrol tax).

I'm not going to argue about whether it would be better to push that all onto legacy ICE users, but something or other will need to be sorted out soonish as they plan to phase out sales of new ICE vehicles by 2030. It will take a while to flush out the existing fleet, but it will increasingly be a problem of who pays for the roads?

Will it just be everyone who is too poor to upgrade? It feels decoupled from the carbon usage to propel the vehicles so you can't just jack the carbon tax without goofing everything else & subsidizing drivers as the electricity is fungible.

Eventually it seems like it will need to just be a road tax & be like registration + some miles & weight & whatever else driven calculation. + then also carbon tax the ICE fuel and the EV juice at whatever it is.

Personally, I think processed food is literally poison. This is based on my experience living across the street from a 7/11 eating primarily processed prepackaged foods, whatever hot garbage wrapped in plastic they had under the heat lamp multiple times a day for a month.

Now I mostly eat spinach, lentils, organic granola, yams, brown rice, occasional fish. Cognition is better, sleep is better, energy is higher. I don't personally believe the body can get used to processed foods, I think it's much more likely that one might simply forget what it felt like to eat a normal diet and feel regular all the time.
