sapientiae3··on PCB DIY? Tutorial for Making Printed Circuit Board (PCB)
For fast prototyping I’ve started using jlpcb.com and even moved from Eagle to their easyeda designer - having a library of components that are in stock, without having to find and verify the footprint makes it a thousand times easier, even if the design software is pretty basic.
sapientiae3··on The Abolition of Work (2002)
It’s strange that people seem to think that work is always a burden - try do nothing for a few weeks and see how that affects your mood.

Work, while has its difficult moments, and parts that can be very tedious, is one of the greatest things we can do.

No beer ever tasted better than one after a solid day’s work, and being part of the advancement of civilisation, even in some small way is pretty much the pinnacle of human achievement.

If you hate working, I’d say change your attitude or change your job.

sapientiae3··on Request for Technically Risky Projects
A Laser Mosquito Turret for homes, that uses a directional microphone to home in on the target.I don’t believe that it would be difficult to build the laser part, but the difficulty would be in making it safe for home use.
sapientiae3··on How a star explosion may have shaped life on Earth (2015)
The thing I wonder about, is that presumable we can control temperature, pressure, magnetism, electric currents, elements and pretty much everything we know and understand in the physical to a relatively fine degree. We can simulate most environments that have existed on the planet over its existence, and yet with all that control, we cannot create even the simplest of life. We can manipulate it, alter it, destroy it - but we cannot yet create it. So either we don’t understand things nearly as well as we think we do, or there are some things that we don’t even know about yet.
sapientiae3··on Ask HN: Does anyone else press keys in wrong order for certain words everytime?
I’m convinced this is a result of typing on a keyboard - it seldom happens when I’m writing.

I think that after a typing for a while, your brain tries to introduce some optimization, i.e. while your one finger goes for the letter ‘t’ (my left hand), your brain queues up the letter ‘h’ for another finger on your other hand. Quite often, and possibly because I’m right hand dominant, the hand going for the letter ‘h’ gets there first. It usually happens with the same pairs of letters.

It would not surprise me if keyboards have introduced whole new kinds of dyslexia.

I have noticed this has crept into my writing occasionally - if I have been typing a lot - usually with the same pairs of letters. I will write the second one first, and then go back and insert the first one.

sapientiae3··on Math is an insurance policy
> As long as the dumb AI is unable to guess our wishes, there will be a need to specify them using a precise language. We already have such language, it’s called math. The advantage of math is that it was invented for humans, not for machines. It solves the basic problem of formalizing our thought process, so it can be reliably transmitted and verified

The same is true of most programming languages - they were all made for humans. Math has the advantage of being to prove formally that it solves the problem, but that isn’t a requirement for most software.

> If we tried to express the same ideas in C++, we would very quickly get completely lost.

Same is true for many things that you can express in C++, but not in Math.

Math used this way is essentially just another programming language - with massive advantages in some circumstances, and massive disadvantages in others - I can’t find any argument in this article as to why it is a better bet than any other language.

So far, this is the best attempt I’ve seen to solve the problem: https://coil.com/
sapientiae3··on Ask HN: A New Decade. Any Predictions?
Marriages and having children will become less and less popular, and under-population will start to be a real concern for economies.

Governments to start / increase incentives to get married and have kids.
