squaredot··on CEO pay skyrocketed 1,460% since 1978: CEOs paid 399 times as much vs. worker
Overpaid with respect to what? The comparison CEO-worker is not explicitly stated, but it's not very hidden either.

The scale linking cost to quality of a good is not linear. People often pay twice as much for something that is only 10 percent better. Prices are a matter of allocation, not value.

These remarks about the salary of the last percentile of the population only serve to raise controversy.

If you want to see how people's well-being has evolved, you have to make somewhat more intelligent comparisons: for example by looking at what people can afford today compared to 50 years ago, or through quality of life indexes. The only thing that has changed for the worse seems to me to be the cost of real estate in the big cities, because of an obvious concentration of the population in them and not because the 1 percent of the population has bought everything.

But outraged people will always find something to be outraged about.

squaredot··on Numbers that explain Intel’s decline
I miss that the comparison is made only on the base of growth, without mentioning the absolute size of the companies, or the volume of their sales.
squaredot··on Compiler Errors for Humans (2015)
I would love to have something like this. With Julia, a programming language that I like very much, it's really a pain.
squaredot··on ‘Some things never leave you’: Poverty’s indelible marks
I agree on this. Poverty, in this sense has, more to do with being than with having.

A friend of me recommended to me on this subject the book: Life at the Bottom: The Worldview That Makes the Underclass (https://en.wikipedia.org/wiki/Life_at_the_Bottom).

squaredot··on Proof of work is temporarily illegal in New York
I wouldn't paint everything in black and white. For what concerns the discussed legislation, I think it would be more correct to legislate about goals and leave everybody free on how to achieve them (when needed).
squaredot··on Socrates on the forgetfulness that comes with writing
As my ancient Greek's professor used to say, by looking at the class taking notes: "Why do we write? We write to forget!".
squaredot··on Understanding USB Type C: Cable Types, Pitfalls and More
I long for the day when we ditch HDMI for thunderbolt!
squaredot··on Understanding USB Type C: Cable Types, Pitfalls and More
Sadly this is probably the best strategy. As the Chinese saying goes,

  "He who buys the best cries only once."
squaredot··on Strange Attractors
Maybe the most famous is the Lorenz attractor, arising from the Lorenz System (this is one of the simulations shown in the website). In Wikipedia you find a description of the system

squaredot··on Improve your turning
> Wouldn't it just be better to play a sport or do an activity that required turning?

I would suggest Tag. Maybe is not good for learning, but if you survive, you're definitively good.

squaredot··on California’s last nuclear power plant gets $1B funding to extend life
That seems good news. From what Wikipedia says, the power plant should generate 16'166 GWh per year. The investment should keep the power plant operating during 5 more years. That is

  220 M USD / 16'166 GWh = 0.013 USD / KWh
On top of that, it comes production cost, which I don't know. For comparison, the cost of electricity is about 0.16 USD / KWh.

I think we should retire nuclear power plants, only after we have replaced other non-renewable carbon-emitting power sources.

squaredot··on Little languages are the future of programming
> you still have to overcome the hurdle that people just _don’t want to spend time learning your one-off language_

That's an important point. Maybe as an academic someone is more inclined in learning new languages for the sake of intellectual interest, but on the engineering side, having uniformity of language is a big plus.

I ask myself, by the way, if the author misses the point not considering that all code that the programmer writes is translated in machine language / byte code of elementary instructions: those instructions are the primitive language. But the programmer uses a more elevated language as he wants something more expressive.

squaredot··on LG announces the first 1440p 240Hz OLED monitor and it only costs $999
Question: is 240Hz beneficial in practical terms wrt let's say 120Hz?
squaredot··on Just a bunch of idiots having fun: a photo history of the LAN party
> I think the comment that it was harder to be an asshole because someone would just ask you to leave (physically! With your equipment!) is quite relevant. It’s way too easy to be a jerk online now.

Maybe the big difference is that you would do a LAN party with friends, whereas you would play online mostly with unknown people.

squaredot··on How to Use Exceptions Correctly
> You should think really carefully about using exceptions in situations that don’t correspond to the preceding section. One particularly common inappropriate use of exceptions is for signaling “logical errors.”

> A correct program should not do things that are undefined.

I don't see how "logical errors" and arguments of a function with undefined consequences would be really separated use cases (the author makes the example of square root of negative numbers). But I agree that exceptions are a type of meta programming that should not be intrinsic part of the logic of the program.

squaredot··on One in five who voted for Brexit now think it was the wrong decision
I am not sure if the state of the UK economy would be substantially different without Brexit. Most of the problems would be the same, maybe with a slightly bigger carpet under which to hide the dirt.
squaredot··on Everything in Tech Seems to Be Collapsing at Once
I agree. The other day someone commenting the layoffs of meta, noted that the company has still more employees than at the end of last year. These changes are bad for the people involved, but even if the numbers are big, their relative amount (percentage) seems to me more like a temporary swing.
squaredot··on Overhyping hydrogen as a fuel
Last year I read the following post regarding the application of hydrogen on ground transportation, simple and insightful. It basically explains why it doesn't make sense to use it for that particular application.

squaredot··on Topology Without Tears
The content of a book is always more important than its form, but we cannot get to its content if not through its form. What I don't like here is the general Microsoft Word-like feeling of the book. What I like is the use of colors and layout that makes it easier to find definitions and other concepts.
squaredot··on What You (Want to)* Want
It happened to me to think about this (but from another perspective). It seems to me that the sentences "I want [A]", where A is an object outside me, and "I want [to want A]" are essentially different. But the sentences "I want [to want A]" and "I want [to want to want A]" are not really different since both have as object my own will. Or said in another way: wanting to want something is already wanting something.

Moreover an essential differentiation that is not addressed is the difference between desire and will (not easy).

squaredot··on Ur
I can share that feeling. However, more than the thought of passing on what is ours, what such a chronological fact inspires in me is the awe of realizing that a city like this represents a history within history. And like that there are many more.
squaredot··on What if regular exercise is the best cognitive exercise?
>Robots still have a hard time navigating terrain and manipulating stuff

The author argues that doing things at higher pace should be cognitive intensive. But robots are not bad at doing things fast: if they can do things, they can do them also "fast" (at my understanding)

squaredot··on The lonely runner conjecture
I like very much this conjecture: easy to grasp, with some intuition you can understand why it is plausible to hold. No general method has been discovered to settle the matter, only proofs for specific cases (up to 7 runners apparently).
squaredot··on Will Twitter outlast this lettuce?
The greatest threat to an already established project is not an earthquake, but the unperturbed erosion of time that causes it to fall into insignificance. Trying to ignore all this attention given to Twitter, let's see a year from now....
squaredot··on Why talent sorting in Germany is flawed
I agree with that. In addition to that, German students who want to go to elite schools also go abroad (like ETH of Zurich), this is probably an effect that is unknown to US people.
squaredot··on Scientists Increasingly Can’t Explain How AI Works
I think these kinds of articles are geared toward people who do not know (even superficially) about the models. Perhaps the sentiment they want to elicit is "If the person who created these models cannot explain how they work, then he is not so different from me."

squaredot··on Group Chat: The Best Way to Stress Out Your Team
The larger a group is, the less important it must be that the information shared reaches each individual. You use the group to share information in order to reach someone, not everyone.
