The Untethered Soul: The Journey Beyond Yourself by Michael A. Singer | Goodreads
The Untethered Soul struck a chord in me because it encourages detachment from this never-ending feedback inside our brains. "The best way to free yourself from this incessant chatter is to step back and view it objectively," Singer writes. "There is nothing more important to true growth than realizing that you are not the voice of the mind--you are the one who hears it."

Singer goes on to say,

If you watch it objectively, you will come to see that much of what the voice says is meaningless. T...

China Is Paying for Most of Trump's Trade War, Research Says | Hacker News

It gets scarce, useful stuff (iPhones, raw materials, food) in exchange for green bits of paper that the USA can print an unlimited supply of. The green bits of paper are usually invested back into the USA creating jobs and other economic opportunities (no point in hoarding it if it gets inflated).

Adding lanes doesn't reduce congestion. So what is TxDOT doing? - HoustonChronicle.com
IN A 2014 study of 228 U.S. cities, two economists at the University of Toronto found what they call "the fundamental law of road congestion," which is known as "induced demand" or "induced travel."

Even when you account for population growth, the law holds. The easier it is to drive, the more people do it. Adding capacity — widening a freeway by a few lanes or building a new one — makes driving more attractive, right up until the added capacity gets used up.

It is almost axiomatic. Over tim...

We investigate the effect of lane kilometers of roads on vehicle-kilometers traveled (VKT) in US cities. VKT increases proportionately to roadway lane kilometers for interstate highways and probably slightly less rapidly for other types of roads. The sources for this extra VKT are increases in driving by current residents, increases in commercial traffic, and migration. Increasing lane kilometers for one type of road diverts little traffic from other types of road. We find no evidence that the ...

Then, in 2000, the rules changed. Researchers were required before the study started to say what they were looking for. They couldn’t just mine the data afterward looking for anything that happened to be positive. They had to report the results they said they were going to report.

Before 2000, researchers cheated outrageously. They tortured their data relentlessly until they found something—anything—that could be spun as a positive result, even if it had nothing to do with what they were l...

Philosophy Has Made Plenty of Progress | Hacker News
Bertrand Russell:

Philosophy, as I shall understand the word, is something intermediate between theology and science. Like theology, it consists of speculations on matters as to which definite knowledge has, so far, been unascertainable; but like science, it appeals to human reason rather than to authority, whether that of tradition or that of revelation. All definite knowledge—so I should contend— belongs to science; all dogma as to what surpasses definite knowledge belongs to theology. But be...

By comparison, Microsoft’s search engine Bing generated $1.7B in revenue in 2017.

That year, bitcoin was involved in less than 0.5 per cent of the world's cashless transactions, they said.

As the currency becomes more common, researchers said it could use enough electricity to emit about 230 gigatonnes of carbon within a decade and a half. One gigatonne is equal to one billion tonnes of carbon.

The problem with Atlas Shrugged is that it doesn't go far enough. And so, to correct that, here's an addendum, a modest proposal to supplement Ayn's book.

We're taxing the wrong people. Why are we taxing rich people more than poor people? Rich people don't need government services. If they want a highway, they'll build it themselves. If they need electricity, they'll build a god damn dam. It's poor people that need the government to build these things for them. So, the tax structure should work...

The State of Agile Software in 2018
- The point is, the team doing work decides how to do it. That is a fundamental agile principle. That even means if the team doesn't want to work in an agile way, then agile probably isn't appropriate in that context, and [not using agile] is the most agile way they can do things in some kind of strangely twisted world of logic.

- When I summarize agile to people, I usually say there's two main pieces to it. One, I've already talked about, the primacy of the team, and the team's choices of how they do things, but the other is our ability to change rapidly, to be able to deal with change easily.

- The third thing that I want to stress is the importance of getting rid of software projects as a notion. Instead we want to switch to a product-oriented view of the world where instead of projects that you spin up, run for a while and then stop; you instead say, "Let's focus on things that are much more long-lasting and organize a product team around that." Another way of thinking about it is: what are the business capabilities that your organization has, and then organize the teams around those.

- When [at Snowbird] we were talking about names for agile software development, Kent Beck suggested "conversational", because there should be an ongoing conversation between software developers, business people, and anybody involved in making that customer experience better.

- I think Ron Jeffries joked that Allistair Cockburn's approach to agile was "come together in peace and harmony, deliver software every week, and do a retro every time to figure out how you can improve".

In particular, one of the really central things that impressed me very much about the early agile advocates was this realization that people are operating at the best when they choose how they want to work.

When we talked about the Agile Manifesto and laid out the four value statements, with most of those value statements, we didn't care very much about what order they came in. But we did have an opinion about the first one: which is "Individuals and Interactions over Processes and Tools". To me that crystallized a very important part of what agile thinking is about. If you want to succeed in doing software development, you need to find good people. You need to find good people that work together at a human level, so they can collaborate effectively. The choice of what tools they use or what process they should follow is second order. I thought that's a very important statement to come from what was basically a gathering of process weenies. I mean we were all process guys to some extent or other, and yet we were acknowledging that what we were talking about was actually of secondary importance. What matters is that the team chooses its own path.

It goes further than that for the team should not just choose the process that they follow, but they should be actively encouraged to continue to evolve it and change it as they go. One of the things about any kind of agile processes or agile method is that it is inherently very slippery. It changes week to week, month to month. One of the quotes that I used to flash around people was "if you're doing Extreme Programming the same way as you were doing it a year ago, you're no longer doing Extreme Programming".

- retrospectives are clearly a technique that lots of people find to be really very central.

- This is a reaction against the whole Frederick Taylor, separate process people.

He's probably one of the most important figures in the history of the 20th century in terms of how he's actually affected people's day to day lives. He was from the late 19th century, in America, and he was very interested in trying to make people more efficient in the industrial workplaces that were developing at that time. His view of the average worker was that they were lazy, venal, and stupid. Therefore you didn't want them to decide how they should make a particular piece of machinery, but somebody else, somebody who was a more intelligent and educated, they should figure out exactly the best way to do it. Even going down to: do I do this and then that or do I do that and then this. This is a very scripted sense of motion and movement. The whole time and motion industry came out of that. At the heart of this notion was that the people who are doing the work should not decide how to do it. It should be a separate group of planners who does this, and that strongly affected manufacturing and factory work through much of the early 20th century.

And it affected the software industry as well - people said, "we need software process experts to figure out how to do things, and then programmers just fit into the slots".

- The agile movement was part of trying to push that, to try to say, "The teams involved in doing the work should decide how it gets done," because let's face it, we're talking about software developers here. People who are well paid, well educated, hopefully, well-motivated people, and so they should figure out what in their particular case is necessary.

- And yet what I'm hearing so much is the Agile Industrial Complex imposing methods upon people, and that to me is an absolute travesty.

- "I'm refactoring our software at the moment, so it's going to be broken for the next two weeks." Bzzz - that's not refactoring. Refactoring is small changes, each of which keeps everything working. It doesn't change the observable behavior of the software, that's its definition. And I should know because I was the one who got to define it.

Refactoring is lots of small changes, none of which change the observable part of the software, but all of which change its internal structure.

- So my three things, that we should face as challenges:

1. Get rid of the Agile Industrial Complex and the idea of imposing stuff on teams. Let teams work out the way they should work themselves.
2. Raise the importance of technical excellence, and never forget that when writing software, the technology side is really vital, and
3. organize around products.

Did I just waste 3 years? | Hacker News
Yes. At this point, recommending that a 9-5 programmer quit their job to work on an indie game is equivalent to suggesting a PR writer quit their job to write the next Great American Novel.
