numtel··on ‘Silicon Valley,’ S6E2 – a billion dollars to violate your principles
No, you missed the point. The "teaching a man to fish" includes all the knowledge, including how to make the pole.

Coercive economic dependence drives exploitation and disparities.

numtel··on ‘Silicon Valley,’ S6E2 – a billion dollars to violate your principles
Philanthropists give money to causes that do not result in the systemic changes necessary to reduce their wealth to a small multiplier of the average person's.

It's the old saying: "give a man a fish, he'll eat for a day, teach him to fish..."

Philanthropy will never solve the fundamental problems with our economy.

numtel··on ‘Silicon Valley,’ Darker Than Ever, Captures the Bleak Mood of Tech
Laws generally come from practice: first "de facto," (by force) then later "de jure." (by law)

Those regulations will exist when there is less political friction required to enact them. When workers unionize, they take the first step into "de facto" practice.

numtel··on React Concurrent Mode
Lithtml implements declarative DOM using string literals like this very efficiently.

I'm of the opinion that sticking with React when Lithtml exists is just fear of writing vanilla classes.

numtel··on Facebook Bought a Police Force
Police departments exist to protect property. Every wealthy individual or large business sets the PD's agenda by design.

In order for less-wealthy people to effect the agenda, they can vote or protest but these are significantly less direct than the influence that property ownership provides.

I'm not saying this is good but that it's just the way it is.

I wish the article provided an analysis of different models for maintaining order but the article seems more about causing outrage than finding a solution.

numtel··on Facebook Bought a Police Force
I'd be the first to condemn police brutality but for the expensive property they have in the police department's jurisdiction, Facebook paying what amounts to elective taxes in order to improve security seems totally reasonable.

As someone who does not use Facebook and considers it deeply flawed, nothing presented in the article should cause alarm and it only seems like a misguided attempt to discredit the company.

numtel··on Make More Land
So we've already destroyed 99% of wetlands in California in the last 150 years, let's play hot potato with the small patch that's left?

The entire central valley was a marsh. The delta is the small part that still slightly resembles its natural state.

Look at this picture of Sacramento from 1857 surrounded by ponds and wetlands:

numtel··on 24-Hour Solar Energy: Molten Salt Makes It Possible
Pretty soon we won't even need all these parts. If Metal-Organic Frameworks (MOF) take off like these reports describe, we'll be able to irrigate deserts passively.

numtel··on Ask HN: Who is building something that will change the world?
Metal-organic frameworks that can pull water out of the air passively hold promise to completely reshape our relationship to the land.

Irrigation without building canals, water generation at the point of use... If this is as good as they hope, this is the solution to the most fundamental of our political problems.

numtel··on Cryptocurrency Startup School
Counterfeiting is a minor issue in our daily lives because so much resources have to be devoted to keeping it that way.

"By 1865, up to one-third or even one-half of American money in circulation was fake." [0]

Governments regularly have to redesign their bills in order to prevent counterfeiting.

Extreme punishments are given for the crime of counterfeiting.

It's not just private actors to worry about. Opposing nations could destabilize an economy.

When counterfeiting is not a concern and a currency system can be created with very little effort, we can make currencies that we have more agency over.

The demand isn't for a cheaper way to combat counterfeiting but for greater agency over how the money supply is formed.

There is a massive, global call for reduced wealth inequality that existing governments have not been able to address. I'm not certain that cryptocurrency can do it either but it does seem like a possibility.

There's no reason a cryptocurrency cannot be paired with judicial institutions that provide recourse for lost or stolen funds.

The innovation of cryptocurrency is simple and undeniable.

Fiat money requires armed forces to secure its supply against counterfeiters.

Cryptocurrency uses math to defeat counterfeiting.

numtel··on Life as a cancer patient: ‘it feels like dying from the drugs meant to save me’
That's so many steps. All I do is put the flowers on parchment paper or any surface in the oven for 30 mins at 245F. There's no need to put it in capsules. It stays fine in a bag for months as long as it's dry enough where you are. I find weaker cannabis is actually nicer for dosing because then it's easy to guage by sight. Just chew up the flowers and swallow. The taste isn't great but it grows on you.

To get started, I'd say eat an amount about the size of a pea then you can eventually find a schedule and dosage that gives desired effects. With more frequent dosing of smaller amounts, (4-6 hrs for me) you can have the benefits while keeping enough tolerance on the mental cloudiness to not get headaches/overwhelmed. There are definitely unique benefits to high-dosage meditative experiences though too.

As someone taking cannabis for breathing difficulties, when I realized I could use such a simple preparation to make it edible, it made life so much easier.

numtel··on Accelerationism
Sorry if that point was hazy. I'm in agreement with your comment but those implementations of national economies operating on Marxist principles were stifled greatly. WW2 caused much greater destruction of the USSR than the US. The US' anti-communist military actions, and economic blockades all existed because of a belief that allowing any communism ultimately leads its spreading everywhere.

A rephrasing would be: We don't know for sure that a Marxist type system does not work because we have so few examples. Maybe we just haven't tried enough variations to find a version that compiles cleanly.

numtel··on Accelerationism
> There is no way to A/B test history.

This is the first thing you learn as a Political Science student in university. The "science" half of the name is somewhat lacking when you can't experiment.

> We now know that Marxist type systems of the sorts deployed by Lenin and Mao don't actually result in a better world and in many cases result in a worse one

We don't know this. There's a lot more to economic security and human rights than private vs state control of production.

> We once had this in the American West, but no more, so we should hurry up and build more rockets.

While a frontier can provide some space for experimentation, redundancy is the real cure.

We haven't done this as a society though since there is an advantage to large scale when securing a nation's economy and currency with armed force.

The interesting new technology doesn't seem to be cheaper rockets but instead a new way to make sure our money is valued as we wish. Cryptocurrency's method of securing transactions against counterfeiters using math enables small-scale economies to operate without wasting too much resource on keeping order.

A system where cities/towns have more sovereignty would enable greater diversity and experimentation because a failure would be much easier to deal with.

Thousands of cities with each their own policies of how wealth spreads is the diverse dream I wish for as the world shrinks into fewer languages, customs, and ideas.

The local bus service in my city between the Bay Area and Sacramento reduced frequency and coverage last year. Their suggestion was to just use a ride-sharing app. It's not just cab companies.

It's the extraction process that's the problem with shale, moreso than the burning of the gas.
numtel··on Gpu.js – GPU Accelerated JavaScript
GLSL isn't that much different syntax that Javascript. If you write it directly you get the fun of using types. And WebGL2's support of GLSL ES 3.0 brings features that make it much more handy for compute operations like bitwise operators. It's really not that complicated to write a compute function without any kind of library. Just throw up 2 triangles that cover the output and scale your canvas to the match the number of pixels you want to each 32 bits of output.

My credit union had that for years but you had the option to choose from a set of available images.

They replaced it last year with mandatory SMS 2FA. I immediately sent them a message about how insecure it is but never received a response. What a terrible regression.

numtel··on Ask HN: What was the one book that you read and it actually changed your life?
Paraphrasing Cory Doctorow, "be worried about the person who only reads one book." [1]

Your life changes when you read many books from many authors.
