> this elite projection describes the common phenomenon of outsiders (and even local elites) disparaging LA for having no/crappy public transportation, which is odd to me as an multimodal angeleno who gave up my car years ago.

Los Angeles has a transit mode share of only 5%, which is extremely low for a principal city with a metro population of 13 million. This is a good indicator that its public transportation is indeed very weak.

To be sure, though, they've been steadily improving it.

The point that combining kernels lets you compose arbitrarily complex functions could come in the beginning. That's sort of why GPs are so exciting in the first place.

In particular, there's a kernel we could call a "change point," which is a way to have a totally different model fitted before a point in time versus after. It's used frequently in Automatic Statistician fitted models (https://automaticstatistician.com/examples/) which in my opinion are the state of the art of what you can use GPs for. They also developed a "LISP" like representation of the GP kernels, which lets them sample functions, fit them, and publish the simplest ones.

You can see an example of, "Create GP functions and try fitting them" here: https://github.com/probcomp/notebook/blob/master/tutorials/e... . Near the end of the notebook, you can see the "source code" of the fitted GP function. Note this implementation supports change points, but does not happen to need them on the sample data.

But generally, I wonder in which applications GP shines.

On the one hand, with its emphasis on time series data, GP has a lot to offer to finance, especially options pricing. On the other hand, GP boils down to "the near future looks a lot like the near past," which most people already know.

Clearly, what we want to know is: when will change points occur? Whoever cracks that nut has found GP its breakthrough application.

It should be clear from the example that some form of fitting over the generation of "Gaussian Process Programs" is a good first step.

Demand is high for both new and used EVs in Norway.

EVs are free (or significantly cheaper) on most toll roads, parking, and pay at most 50% of regular fees for ferries.

Owning an old short range EV as a second car can easily save you 1800€ a year[1] in toll fees alone. Even an old electric wreck is easily worth 10000€ just in reduced toll fees if it's able to do 5 more years of just rolling past that toll station barrier. Even banged up and with a 50% degraded battery the car is still valuable, as long as it can get you to work and back home again.

There was a time some years ago when you could essentially cover the down payments for a Tesla Model S from saved ferry fees if your daily commute crossed Trondheimsfjorden (cost like 30 USD per way, this "bug" has since been fixed, you now have to pay 50% of the ticket).

You know I never even considered the cable itself in the whole usb-c equation. And labeling them is a hard problem to solve. Not technically, but aesthetically. We COULD just make different colors mean different things (But then you have to remember the colors...), but everyone wants a specific color(me included).

Text labeling could work, but could get out of control, especially at the rate that the standard is changing. Would it need to list the specific features the cable supports? Or can I assume that a cable labeled with 'Thunderbolt' will be compatible with all future iterations of Thunderbolt?

Maybe we can do something like resistor color codes with colored bands to make a rainbowed venn diagram of cable features. Surely that's a good idea which will only decrease complexity :P
One other resource that a lot of people miss but is quite profitable is selling packages relating to your niche.

I haven't tried your app but let's say your app helps people better manage time, then you have a perfect audiende that may be interested in buying a small ebook about productivity and how your app can be used to double it. You already have a list of prospects who trust you and use your product. Upselling them is easy if you can create a great resource that will help them get the most out of your app and achieve the goal (for which they're using your app) more quickly or lazily
Weird thing is, I've bought glasses at Lenscrafters before, and I've had the same experience as the independent eye doctor, they took the order and it took around a week to fill. I do have a strong prescription with astigmatism, so maybe that's the reason? I do recall hearing about "glasses in an hour" on commercials but I've never been offered the "hour" version. Maybe they can only make some of the most common prescriptions in an hour?
The biggest mistake they made was ordering 3,000 decanters and 1,500 aerators. These were not custom products so why was the order quantity so high? As an importer it's clear that the agent they dealt with in China knew it was a one-time thing and juiced them on the quantity. Realistically they should've ordered 100 of each as a quality check, listed them for sale, and seen how it goes. Minimum order quantities rarely are.
My polyrepo cautionary tale: Two repos, one for fooclient, one for fooserver, talking to each other over protocol. Fooserver can do scary dangerous permanent things to company server instances, of which there are thousands.

Fooserver sprouts a query syntax ("just do this for test servers A and B"), pushed to production. Fooclient sprouts code that relies on this, pushed to production. A bit later, Fooserver is rolled back, blowing away query syntax, pushed to production. "Just do this for test servers A and B" now becomes "Do this for every server in the company". Hilarity ensues.

Hurdles everywhere you look. Too much barriers and tariffs on imports, too little enforcement of rules, too much uncertainty with logistics and politics and occasionally, threat to life, money, and product.

Governments have long had to walk the balance between protecting domestic industry, raising revenue, supporting entrepreneurs, benefiting from globalization, and protecting foreign states and other external parties from exerting too much influence. It's not sensible to place high tariffs on products for whom domestic production is minuscule and unlikely to be competitive, and which enable a value-added product to be made domestically instead, but political and economic desperation can enable this shortsightedness.

One can look at Brazil to set realistic expectations. It shows what happens when a large country full of potential institutes a scheme of extreme protectionism, and that the struggle with vast inequality and dysfunctional politics frequently cause issues for people and industry, despite the outward rule of law. But it also sets an aspirational note for progress in trade, innovation, and quality of life.

The other issue is the role of direct foreign investment. Changing economic realities and political backlash against the taste and legacy of colonialism have made western states less likely to invest in Africa. China has been eager to capitalize on this, much to the concern of western strategists and journalists. These days, China is rethinking the debt load and shelving many projects, but the geopolitical concerns remain. Nonetheless, China built and operates ports, railways, schools, apartments, and factories. These are tangible infrastructure that sticks around even if the institutions around them change. And infrastructure is a prerequisite of delivering reliable institutions.

I would have instead done like this:

(tldr; use a sine and cosine function regression like a linear regression. Think like solving for a free angle and a free phase instead than for a free bias and weight).

1. Convert the hours to an angle in degrees or in radians (a simple linear transformation).

2. Take the cos and sin of the angle to get the x and y position in a plane, respectively.

3. Introduce a time axis such that the thing doesn't draw a circle but rather an helix (like DNA).

4. So we now have a ton of 3D data points: (time, x, y). Create a ML model to fit a sine and a cosine to those data points to match them perfectly. Your model has only 2 free parameters to optimize for: a shared phase offset and a shared frequency. The sine uses (time, y) and the cosine (time, x).

5. Initialize the model with a random phase offset and a frequency ideally already close to the one you think you have. Don't initialize with a too high frequency to avoid fitting just Nyquist-frequency-close-noise.

6. Optimize! (With the least squares.) I guess that you might congerge only to a local minima and need to try different randon starting frequencies if you fail to converge.

7. The answer to your problem is the now-optimized free parameter of the frequency. It won't sit between two bins of your fft anymore.

Related: https://stackoverflow.com/questions/16716302/how-do-i-fit-a-...

Note: This link contains images picturing the transformations I try to explain.

Disclaimer: I didn't do that yet, this is just off the top of my head. If I said something wrong, please comment. Mostly about a wrong convergence to Nyquist freq or something like that (?).

In the end, this way, you won't have discrete fft bins. You'll approach the problem orthogonally to that: you solve for finding the one best fft bin (frequency) directly.

In other words: solve for the content in the exponential of "e" as free parameters, and for one such frequency and phase offset instead of many bins.
Yep I've found this too. That said, Amazon returns service is actually pretty decent one the few times I've had reason to use it. I've never even had to send the items back - they just refund it and suggest ordering again if I want to.

Not sure if they'd do that for like a TV or something, but certainly anything under about £50 is an immediate refund with no-questions-asked it seems.
> The sole political/military push toward "personal car free" society, concentrated in megacities serve the purpose to easier control people:

People being concentrated in larger cities is mostly an outcome that comes from the free market. Higher population levels helps bring about higher levels of economic productivity, and people go where there are jobs.

Having decent public transit -- and walk and bike options, for that matter -- in urban areas is just good policy. No conspiracies necessary, it's just good to have more options, especially more geometrically efficient ones when space is at a premium.

Trying to ignore transit just gets you to LA's position, where they built mountains of freeways and got the worst traffic in the country in return, with poor options to bypass that traffic for most of the local population.
His own argument is bust in that in that success and failure are themselves asymetric, so it's a moot point.

"Failing" or "not succeeding" is the default and anyone can do it. In fact, the majority of people will never "make it" and most people even who do semi-well will live comfortable but not amazing lives.

"Success" which he seems to judge as perhaps being a somebody or doing something notable follows a power law distribution. It's rare.

Ok, so most people work the 9-5. And what does Taleb have to say about that? He says "ok, well, yes, if you're a slave then IQ seem to predict you'll do better in that particular game". Right. So it is a good predictor of how well you can expect someone to do when they play the game that the vast majority of people play.

So... In other words it's roughly speaking useful.

Don't even get me started on on his term IYI (intellectuals-yet-idiots). Implying that there are people who are intellectuals that suffer no bounds to their rationality nor any partisan or ideological bias. Right. Only an IYI could even come up with such a concept. I see this all the time. Disagree with someone in academia? Oh, well they are a pseudo- intellectual! Or perhaps you might consider the alternative that you just used pseudo-reasoning to reach your psuedo-conclusion.

He draws an analogy between "best measure" proponents and "Value at Risk" proponents.

Ok. Well let's lay out the tools that will help us analyse that analogy. In the book Shortcut John Pollack describes the 5 things that characterize an effective analogy.

1) uses the familiar to explain the unfamiliar

2) highlights similarities while obscuring differences

3) identifies a useful abstraction

4) tells a coherent story

5) resonates emotionally

It certainly resonates emotionally if you accept the premise that it tells a coherent story. It certainly tells a coherent story that relying on a bust metric will catastrophicly blow up in your face if you accept the premise that it identifies a useful abstraction. It identifies a useful abstraction that a metric might not actually be measuring anything real if you accept the similarities and don't look at the differences.

I'm not part of the finance world and don't have a good enough grasp to deconstruct the analogy enough to figure what the differences are and whether it is a good or a bad analogy, but I wanted to lay out the tools to help people do so.

My gut says thats not a good analogy. If only because people say that well it seems to be the best measure we have and he says that's what the VaR guys said. But then he also says, well yeah if you're talking about the domain in which the majority of people spend the the majority of their lives (the workplace) then yes, it does actually seem to have some predictive power there.

He himself is fooled by randomness.

my concern with ruby. is difficult to see the next feature or what the core devs are planning. You have to allways follow: https://bugs.ruby-lang.org, there is no clear process.

Also, I would like to see the new language changes use more in ruby.

Is a shame that ruby has features that other languages use as super crazy amazing, magical way of doing stuff.

Also, I would like to see it faster, I would like fibers to become more visible to ruby community.

Is a shame that ruby is not in the ML/AI/NLP as other languages. I see people complain about ruby, and how python is the golden boy of languages, but I totally dont like stuff like `__wow__`, `method(self, stuff):`, `@amazing_annotation`, `:= stuff` here, `[for x in y if]`, no so much functional stuff, class with uppercase and other with lowercase. sorry for my rant :)

> I bet you do not know anyone with a moderately used EV with more than five years.

I have a Chevy Volt from 2013. Bought it used. It's now six years old and has nearly 60k miles on it -- 75% of those on EV-only miles. I have almost no decrease in range or capacity. (It was EPA rated to 35 miles range off the lot. I got a real world 30 miles range yesterday, in below-freezing weather with aggressive snow tires on it, in a Michigan winter. When the weather warms up, it will go right back to 35 miles, just like it did last summer).

I'm never buying a gasoline car ever again. I'll buy Volts until they can't be found, and then I'll probably switch to a Bolt or equivalent.

The trick is to buy a well-designed, thermally managed battery. If you are lazy about thermals, the battery will kill itself. (See the original Nissan Leafs, anything from Ford, etc). But that has nothing to do with EV battery tech viability, and everything to do with car companies being lazy or cheap.

A properly designed EV battery will easily last over 10 years and over 100,000 miles. We have lots of examples of this (from Tesla, Chevy, and others) to prove it.
Don't substitute a meme for thinking. The real story is as follows:

Two economists are sitting at home. One says "Lets go out and look for $100 bills in the street." The other says "There are better ways to make money."
I don't know why people still believe that someone with a winning (money making) system is going to share that with others. If a system works that well, nobody is going to sell instructions on how to do it. Maybe they'll share the knowledge with a few friends or family, but they sure won't sell it.

To sell "how to get rich" information clearly implies that the seller is not getting rich. If they were, and even if they were exceptionally generous and wanted to share the knowledge, they wouldn't bother charging money for it.
>USB-C enthusiasts are (from my experience) people who haven't really used it much and think that they will be able to get around with a single cable and a single connector standard. People who actually tried to use it for a number of things quickly realize that USB-C is just the name of the physical connector, which has nothing to do with what the device supports, which in turn has nothing to do with what the (unlabeled!) cable supports.

Well, I'm using it for my monitors, soundcard, power, iPhone/iPad charging, Sony headphones, and external hard disks.

What exactly am I missing from the whole issue, since I don't seem to be having any problems?

Can it be fixed by not buying crappy cables?

I agree that long division measures some dimension of intelligence. But there are so many dimensions that knowing a coordinate in one dimension does not tell you much about coordinates in other dimensions. Taleb's point is that there is correlation, but it's mostly driven by the left side of the distribution.

"Unable to do long division" usually means that this person cannot solve differential equations. "Able to do long division" tells you very little about that person's ability to solve differential equations.

The speed of solving simple problems does not necessarily predict ability to solve really complex problems well. For example, a chimp named Ayumu easily beats humans in short-term memory tests: https://www.theguardian.com/science/2013/sep/29/chimp-intell...
