>This is why John Stewart Mill and Adam Smith advocated for steeply progressive taxes beyond a floor.

That is not correct.

>...Smith's first maxim of taxation, from Wealth of Nations, is that the "subjects of every state ought to contribute towards the support of the government, as nearly as possible, in proportion to their respective abilities; that is, in proportion to the revenue which they respectively enjoy under the protection of the state."

>Taxation in proportion to revenue is not progressive taxation. It is proportional taxation—in modern terminology, a flat tax.

https://reason.com/2023/06/04/adam-smith-wasnt-a-progressive...

In terms of Mill, I think he advocated for inheritance taxes, but in terms of "steeply progressive taxes" he wrote:

>...To tax the larger incomes at a higher percentage than the smaller is to lay a tax on industry and economy; to impose a penalty on people for having worked harder and saved more than their neighbours.

It sounds like you've done plenty of experiments and don't need any theory to make this work, but have you looked at the physics/mathematics of the vibrations? Does the frequency you detect correspond to https://en.wikipedia.org/wiki/Vibration_of_a_circular_membra..., for example? I'm guessing that the interlocking strings are best modelled as a membrane rather than individual strings (https://en.wikipedia.org/wiki/String_vibration) but the racquet head isn't circular, so it's a bit beyond my level of maths to do that properly.

I suppose that to do the maths we'd need to know the spacing of the strings and the mass per unit length of the strings. (And the dimensions of the racquet head, of course, but that must be easy to look up.)

Also, would this work just as well for tennis and squash racquets?

EDIT: Perhaps https://en.wikipedia.org/wiki/Dimensional_analysis would give you the formula, and the constant you could get by experiment, and then the same formula might be applicable to any similarly shaped racquet.

Very sorry to hear about those people.

It reminded me of something from childhood. It’s no comment on this story - just a personal anecdote.

We were on a family road trip, and I was wearing a new pair of cheap sunglasses, feeling way too cool for a kid. As we turned a corner, the setting sun blinded my father. But through my tinted lenses, I saw the wall coming. He didn’t. We crashed hard. My sunglasses flew off, and in that moment, all I cared about was catching them. For a few seconds, I thought that was the only emergency.

That moment left a mark. Now, whenever I start to feel too cool or overconfident, I get a quick flash, like a reflex, to check myself. How stupid will this look if things suddenly go wrong, especially if I could have seen it coming?

It’s made me quietly grateful for all the small, tedious safety rules. Not because they prevent every disaster - but because they sometimes do.

For the record no international court has ruled that the Cambodian genocide was a genocide either. The perpetrators were arrested years or decades after the genocide and charged under a special UN endorsed tribunal for various crimes against humanity, but not genocide... That doesn’t mean there was no genocide in Cambodia, obviously.

Even in cases where international courts did rule a genocide, such as in Rwanda, it usually happens months, years, or even decades after the fact. In Rwanda it wasn’t until the genocide was officially over where the UN entertained making charges for genocide, with a special court established 4 months later (nov. 1994), initial indictments a year after that (nov. 1995) and it wasn’t until 1996 when the first perpetrators were found guilty of genocide. The Bosnian Genocide tribunal took even longer.

In no cases has anybody ever been found guilty of a genocide by an international court during an ongoing genocide.

You are right about one thing though. The term genocide is used politically, but not in the way you are arguing. During the Rwandan Gencocide countries—particularly the USA, but also many European countries—avoided the term, and fought hard against using it to describe the horrors in Rwanda, because under the genocide convention they were obligated to take active role in preventing it, which they had no interest in doing. Usually avoiding the term is what politicians do to avoid their responsibilities.

There are hundreds of decent note taking apps and todo apps. The issue is that almost no one has the exact same needs or workflow for either of those things. I’ve given up on suggesting those things to people and sticking with “whichever one you use is the best”. So the best you’ll ever do is a decent one //for you// but it’s possible that definition may not work for anyone else.

Others should consider Chicory, enabling JVM apps to run wasm code (compiled from Rust or many other languages) at high speed, securely in-process.

JNI introduces a lot of other challenges and sacrifice in terms of portability, memory and retaining observability and control within the JVM.

Chicory even supports AOT compilation to translate wasm bytecode to JVM bytecode for native performance.

No, this is the greatest piece of the RISC OS UI. It makes all other systems save dialogs seem like total nonsense. You just put files where you want them. The only thing is that the OK button shouldn't exist.

I actually passed my discrete math class and final a few days ago and got the big O vs Theta vs Omega question right.

The reality is that companies often underperform their best case possible growth rate. O(n) and O(n^2) are meant to represent the best possible growth rate which may be practically be underperformed.

You may be thinking about algorithmic analysis where the term "worst case" is used for the upper bound, but here, the upper bound represents the best case. Sort of counter-intuitive but the underlying mathematical notation is properly defined.

My viewpoint is that money is a technology, and people will choose whatever technology works for their use. A technology can be designed so that some favored uses are much more likely than others. For our government money, those uses are as a medium of exchange, temporary store of value, and tool of government economic policy. Also, some money transactions are delimited by regulations.

People already choose that their government money is worthless, e.g., the people of Venezuela and Russia. They will risk prosecution to move their wealth into assets valued in dollars or euro's. Even in the dollar and euro zones, people use other technologies for storing and exchanging wealth. Most wealthy people don't store their wealth directly in dollars already.

The value of government money is based on expectations about the future behavior of the government. This is at least a little better than being arbitrary or a collective delusion, in the short term. There are already ways to bet against it if you want.

Ooh blast from the past!

At a previous company we moved off of wkhtmltopdf to a nodejs service which received static html and rendered it to pdf using phantomjs. These days you probably use puppeteer.

The trick was keeping the page context open to avoid chrome startup costs and recreating `page`. The node service would initialize a page object once with a script inside which would communicate with the server via a named Linux pipe. Then, for each request:

1. node service sends the static html to the page over the pipe

2. the page script receives the html from the pipe, inserts it into the DOM, and sends an “ack” back over the pipe

3. the node service receives the “ack” and calls the pdf rendering method on the page.

I don’t remember why we chose the pipe method: I’m sure there’s a better way to pass data to headless contexts these days.

The whole thing was super fast(~20ms) compared to WK, which took at least 30 seconds for us, and would more often than not just time out.

Are there extensions that e.g. use NLP/LLMs/vectors to suggest potential links from elsewhere in ones KB? Could be a fairly straightforward plugin.

(I haven't used Roam personally and have no idea if it even has a plugin architecture or is extensible, but this reminds me a lot of some of the knowledge management work we're doing with corporates)

Header passthrough is nice to have, but there isn't really a standard for it for TLS, and it isn't well supported by most applications that are interested in doing mTLS. Additionally there is a trust component required between proxy and application and while can be accounted for in the architecture between the two a JWT instead passes through nicely and can be independently validated by the application.

Obviously no right answer, but personally I think worrying too much finding the perfect tool instead of just integrating more knowledge to your PKMS is a distraction.

Rolling your own solution is especially limiting in the context of the sheer amount of integrations the popular ones (like Notion for example) support.

You're basically saying you will quickly build something better than the X hundred engineers at PKMS company Y quickly and it will continue to be better than what X hundred engineers will iterate upon.

I think that time is just better spent learning and picking the subset of features that, for example, Notion offers that really improves your learning rate.

In Bill Gates's post about changing his charitable giving goal to give most of it away in the next 20 years, he references Chuck Feeney as someone he admired.

from https://en.wikipedia.org/wiki/Chuck_Feeney

Until he was 75, he traveled only in coach, and carried reading materials in a plastic bag." He did not own a car or a house and wore a $10 Casio F-91W watch

He gave away most of his fortune and required recipients not to reveal the source of the donation.

If you need a little bit more than Joplin (which is a great notes taking app, but not so much of a PKMS), give Trilium¹ a try! (I used Joplin for a little while, and it's a good tool, and it's fine not to chase for more if you don't need it, but if you do, not much beats Trilium, IMO)

Sure, and skipping too many car payments gets your car repossessed, skipping too many mortgage payments leads to foreclosure, etc....

Those are serious consequences, but they're localized to the specific thing or service at issue. You don't lose access to your car because you fail to pay rent on your storage unit. Your house doesn't get foreclosed because your car gets repossessed.

Brings to mind the famous Joseph Heller quote: "At a party given by a billionaire on Shelter Island, Kurt Vonnegut informs his pal, Joseph Heller, that their host, a hedge fund manager, had made more money in a single day than Heller had earned from his wildly popular novel Catch-22 over its whole history. Heller responds, 'Yes, but I have something he will never have … enough.'"

I took the author's use of O(n) vs O(n^2) as a framing point rather than a literal model. It just seems to be missing the forest for the trees. Besides, we can approximate sigmoids with linear or quadratic functions when windowing them. Considering startup as context I think we know what part of the graph we're talking about... Do we see that exponential explosion or is the sigmoid much more flat. Replace the x in your sigmoid with (ax) and is a <1 or >=1?

When someone buys a car that uses gasoline or diesel they just commuted to dumping 50 to 100 tons of CO2 into the air.

Putting an excise tax on those cars tilts the decision to buy gas vs electric strongly away from gas. Which is what you want. The other thing is it sends a very strong signal to manufacturers that they need to stop producing them. Remember the cost of carbon taxes isn't something they pay. The consumer most of whom suck at accounting are the ones.

And punishing people that bought a gas car ten years ago is pointless and immoral. Because they already bought it. And they did so in good faith.

I guess that it works in very low-density places that are close to the city or something like that. But the problem is that the parking takes up space, so, instead of having some kind of transport hub, where economic activity happens (as is usual next to train stations or bus terminals), you end up with a bus terminal/train station in the middle of nowhere, where the only thing you can do is take your car back to suburbia, and furthering its car dependency. And I'm not sure the regular driver is as city-minded as people here to think of the congestion and all that stuff when they decide between taking the car to the city or to the parking lot and then having to deal with the bus and its schedules.

Also, we're talking about buses, not trains. Unlike a train, you can take a (small) bus into a lower-density area, as it is the case in some cities.

I did in fact look at Etymonline for "thesaurus" before I made my comment and therefore chose my words carefully, but not clearly enough. Yes there were books before Roget's that contained the word “thesaurus” (treasury) in their title, including at least one dictionary. But none of these earlier books caused the word “thesaurus” to start to mean a particular kind of book, which it does in English following Roget — and that kind of book is precisely one that contains synonyms and antonyms, and usually does not contain meanings or etymology. So the comment by folex remains weird — for one thing, it uses “stereotype” where “meaning” would be more appropriate.

You are making assumption I want to wake up that early.

Quite opposite - I’m searching for way to completely black out the room since kids will wake up with slightest shred of light, far before daycare starts. And I’m not even living if far lats.

But yeah I still want them for convenience. Problem is I don’t want cables dangling around curtains and battery options are limited.

Because, as the article states,

> The analogy [between asymptotic growth and company economic growth] breaks down when you force or imply something numerically specific about your growth rate, or introduce functions with different growth rates like logs or exponentials. For now we will (somewhat unprincipledly) stick with two sole classes: O(n) and O(n^2). Perhaps choosing a better two functions could more closely explain the growth dynamics of network effects, which could be more exponential. I think the analogy diminishes in value if you try to directly numerically match it to some growth metric.

So the article specifically tries to be unspecific about what superlinearity we're talking about, and also calls it vaguely superlinear. Since O(n^(1+ε)) is arbitrarily superlinear (O(n^1) = O(n), and ε is some arbitrary small amount, making it superlinear by definition, and practically nothing else), it is a good choice when that is all you wish to say.

If you went with O(n log n), you'd get the same questions as with O(n^2): Why not O(...something else...): That's not the point! :-D

Roam has always felt like a bit of a chore -- while it's easy enough to set up backlinks, having to do that one step has always been like a waste of time to me. This is the kind of thing that imo an agentic workflow could do for you:

- Just start typing

- Let the LLM analyze what you're typing, given the RAG database of everything else you've added, and be able to make those kinds of correlations quickly.

- One-button approve the backlinks that it's suggesting (or even go Cursor-style yolo mode for your backlinks).

Then, have a periodic process do some kind of directed analysis; are you keeping a journal, and want to make sure that you're writing enough in your journal? Are you talking about the same subjects over and over again? Should you mix things up? Things like that would be perfect for an LLM to make suggestions about. I don't know if Roam is thinking of doing this or not.

This addresses one axis of development.

I have seen this opinion offered hundreds of times and each and every time I reflect upon the irony that not one of these commenters having trouble navigating the UI, etc to their liking doesn't just ... Make Anki cards about Anki.

There is probably not a specific rule that you can't shoot the shot put out of a canon either.

- Find a way to make it impossible to do the things you're trying to avoid. For Apple products setup Screen Time and give someone else the passcode. I'm sure there are solutions for other OSes out there

- Practice self denial and doing things that hurt, such as fasting and cold exposure (like a cold shower or cold bath). These are good for people in general. I'm not sure how universal this is but doing these things gives me an incredible sense of accomplishment which makes it easier to do other difficult things that I want to do but otherwise avoid

Good luck, these things are designed to be addictive and our biology has not caught up to give us sufficient built-in resistances. This stuff is very difficult, and kudos for reaching out! You can do this!

As a 90s teenager, cryptome.org was an incredible view into the hidden parts of the society. It's where I learned about Echelon surveillance years before its existance was admitted, numbers stations, crypto, spy networks, intermingled with all sorts of other "out there" conspiracy stuff (aliens, Area 51, JFK assassination). It was a pretty key part of the wild wild west of the early web for me. Amazing that the page layout still looks about the same as I remember. RIP.

I tried an amphetamine tablet and it felt like a muddied cloud has been lifted from my brain. I asked my GP to try Adderall and he agreed.

That was ~20y ago. Since then, a lot of hostility has been ginned up by US press and politicians toward adhd meds. That led to state and federal enforcement constantly signalling to Dr's that prescribing adhd meds will earn them extra attention.

FF to today. You commonly need to establish a relationship with a prescriber before they'll consider writing these scripts. Psychiatrists do the lion's share of Rx'ng but they often want to try other meds first. This isn't always a great process but a good psych will work with you if you work with them. It takes time.

In theory, your very best bet is finding other people who are on adhd meds and find out who prescribes it for them and what that process is like. But for how you identify those folks - I have no advice.

edit: Two of my adult kids are on Ritalin variants; Adderall is not a good fit for them. There are also some non-stimulant focus enhancers. Psychiatrists are the specialists in this area.

If you get meds and they help, it can be like having new tools to work with. A therapist can save you some floundering around time - help you get productive with those tools.

Ah, the string spacing cancels out, doesn't it? I'd expect the frequency to be proportional to sqrt(t/d)/a, where t is the string tension in Newtons, d is the linear density of the strings in kg/m, and a is the diameter of the racquet head (assuming they're all the same shape and measured in the same way, which probably isn't true, unfortunately).
