drran··on Hubble captures a black hole that is forming stars, not absorbing them
Of course, nothing can have infinite range in an infinite Universe, because the infinite sum of gravitation fields of an infinite number of objects can create infinite force at any point of the Universe.

At some range, any field will decrease to below thermal noise of medium.

drran··on Danish government makes its new economic model open source
I'm not interested to pay 15k in taxes to receive 5k back as UBI, regardless of economy or stability.

How much you plan to pay in taxes to support my UBI?

Yeah, but People Republic of Alaska may join RF.

Yeah, Russians just want to return Russian Alaska, which is not a part of the USA.

Science is about replication of results.

For example, if Alice did X and got Y, then published a paper about it, and Bob did X and got Y, and Charlie did X and got Y, then X->Y is scientifically proven.

If well known and proven scientist Alice said that X may cause Y, then it is just Alice words, not a science.

drran··on The horizon problem for faster than light travel
But, it doesn't enable time travel. It just makes calculation easier, like «bending» of space-time array.

If you switch from relativity to regular physics with medium instead of pure vacuum (10 years passed since 2012 already, so relativity is busted at this point), then c is the speed of light in medium, so we don't need to bend anything or use negative t to calculate outcomes.

drran··on The Theoretical Minimum (2013)
If you want to understand physics, then you need to build physical models and demonstrations, or perform experiments. If you want to get correct answers and make predictions, or you want to build a virtual model, then you need to study math a lot.

drran··on Format Strings in Rust 1.58
IMHO, this is the language problem. Rust can enforce correct types for all arguments to a function, except when type is erased by use of a generic container, like `String`. It's possible to enforce a `ValidHtmlLString` as argument to a function, with automatic conversion of a `String` into `ValidHtmlString` at runtime, but it doesn't protect from unsafe HTML, so `makeHeader(title: ValidHtml) -> ValidHtml` will happily accept `format!("<h1>{unsafeHtml}</h1>")` as argument.

Maybe, we should create a specialized `format!()` macro, for example: `formatValidHtml!()`, `formatSafeHtml!()`, `formatAccessibleHtml!()`, or just a `formatRestricted!(ValidHtml + SafeHtml + AccessibleHtml, "<h1 role=\"banner\">{safeTitle}</h1>");`

drran··on Format Strings in Rust 1.58
IMHO, your point is valid: currently, it's not possible to enforce a constraint on `format!()` arguments, AFAIK, so we cannot say that all arguments to that format string, which will be used in that API, must implement SafeHTML trait or SafeSQL trait. You should create a ticket or RFC for the problem.

3.8% users are using Steam on Linux, with their shitty support for platforms? Astonishing. That millions of users. It's comparable with XBox market share.

IMHO, somebody should milk this market.

drran··on Apache PLC4X announcing end of community support due to missing funding
Yes, it's because of GPL restrictions: if you use my code, then I can use your (to some extent), so proprietary developers are forced to cooperate, which everyone job easier.

Linux is used by whole planet, but it's not a burden for Linus Torvalds.

Same for KHTML -> WebKit/WebCore -> Blink (LGPL), which is used even by such GPL haters as Apple and M$.

It's because we ran away from contaminated sites.

> We know how to build safer nuclear now than we did 60 years ago when the current gen were mostly built.

I will reword my question: How we can make nuclear safer by 10x in next 10 years? We need them to be 10x safer if we want to have 10x more nuclear plants.

drran··on Why Germans remain so jittery about nuclear power
There are 1) known reasons for known catastrophes, so we can protect against them, 2) unknown reasons for known catastrophes, so we need to make a guess, and 3) unknown reasons for unknown catastrophes, which are not happened yet, including state sponsored attack on a nuclear plant. We cannot be prepared for unknown unknowns, so we need to plan for the worst case scenario. The worst-case scenario for nuclear plant is continent scale Red Forest (about 1M Chornobyl's).

Do you know how to reduce continent scale threat to just the size of a nation or a town?

Nuclear fusion or LENR can do that, because of small amount of radioactive materials and no positive coefficient by design, but how you can do that for massive fission?

Water heaters, cars, washing/drying machines, power walls, battery powered devices. Electric teapot, microwave, cooking stove can operate at half of power when demand is very high. They can report to and receive instructions from a smart power meter.

Continent-wide Red Forest can be achieved with just one nuclear plant.

Nuclear waste is dumped into the ocean already, contaminating fish: Fukushima, La Hague, nuclear bomb testing, etc. etc. We need a second ocean.

There are some rumors (on HN) that Pukin and frau Ribentrop are brother and sister by mother, and that their mother was soviet agent.
drran··on Why Germans remain so jittery about nuclear power
Yeah, but we have multiple catastrophes already, despite the vanishingly small number of nuclear plants. If we want to increase the number of nuclear stations by 10x, we need to make them 10x safer just to keep the number of catastrophes at the same 1/30y level. Do you have an idea how to make a nuclear plant 10x safer comparing to today?

For solar, it looks like falls from a roof are accounted, to make the number scarier. I see an asterisk near to the number for solar, but no explanation of it, nor break down of the number.

Smart grid can solve this problem, when appliances will report of their needs and abilities to the grid, and then the grid will schedule power delivery to meet the demand.

Coincidentally, one of the safest sources of energy also produced the most dangerous and long-lasting problems, for which the only solution so far is to run away and leave the land empty. Luckily, we still have plenty of land to move in. For example, if something serious will blow up in Europe (non-zero probability), we all can immigrate to the USA.

Why «irrational»? It just to add color to your message, or you truly believe that radiation contamination is harmless?
