SI units are attempting to fix standard measurements with perceived constants in nature. A meter(Distance) is the distance light travels in a vacuum, back and forth, within a certain amount of ossilations of a cesium atom(Time). This doesn't mean we tweak the meter to conform to observational results as we'd all be happier if light really was 300 000KM/s instead of ~299 792km/s.

Then there's the problem of not mixing different measurement units. SI was designed to conform all measurements to the same base 10 exponents (cm, m, km versus feet inches and yards) But the authors attempt to resolve this matter doesn't even conform to standardised SI units as we would expect them to.

What is a byte? Well, 8 bits, sometimes. What is a kilobit? 1000 Bits What is a kilobyte? 1000 Bytes, or 1024 Bytes.

Now we've already mixed units based on what a bit or a byte even is and the addition of the 8 multiplier in addition to the exponent of 1000 or 1024.

And if you think, hey, at least the bit is the least divisible unit of information, That's not even correct. If there Should* be a reformalisation of information units, you would agree that the amount of "0"'s is the least divisible unit of information. A kilo of zero's, would be 1000. A 'byte' would be defined as containing up to 256 zero's. A Megazero would contain up to a million zero's.

It wouldn't make any intuitive sense for anyone to count 0's, which would automatically convert your information back to base 10, but it does prove that the most sensible unit of information is already what we've had before, that is, you're not mixing bytes (powers of 2) with SI-defined units of 1000

You're now suggesting to do exactly what the article is about without being aware of it.

But its just kind of mediocre and you're better off actually dealing with the stack if you can actually deal with certain fixed sizes.

Some comparisons between animals and humans just aren't compatible with understanding dose and volume. Some smaller animals eat their weight in food, I just wouldn't recommend basing your own dietary fiber intake on that.

Think about protein folding and enzymes. That's all solved with probabilities and likely outcomes for the structure and the effect it has. Any replicator would already need to prove the things it is allowed to create, adding the items that it is not allowed to create is probaly needed as a safety protocol anyway.

To reiterate, The belief that evolving machines have to match the kind of evolution we're subjected to is illogical. Machines wouldn't be there without us and we wouldn't have what we have now without evolving our machines.

It would certainly be one of the more stranger ways to explain the birds and the bees

>as people and societies become wealthier and better educated (both correlated with intelligence), their reproduction rates drop precipitously.

There is also the unmistakeable influence of evolutionary psychology on people throughout human history, that seems to have accelerated. When people decide to have fewer kids, especially the more affluent ones, doesnt yet point to any biological influence. Other than the correlation between wealth, IQ and genetics. I dont think there are any risks of a reduction of intelligence through evolution. The world population reduction we're seeing might accelerate it instead.

If you could look back far enough and understood most of the enviromental pressures we faced, then we are all lottery winners of our tumultous history.

Things that are close to this value proposition:

Video streaming services

Email

Online game subscriptions

Data backups

VPN

Very few of these actually offer anything for 5$ a month and they do not offer 'customer support' or 'forum support' in the way you would probaly expect from people that offer that for your linux desktop. If anything, I expect the value proposition to be more like custom art pieces, where someone actually sits down with you for an hour, writes down what you want and programs up an entirely artisic desktop representation for whatever theme/idea you have. That would cost hundreds of dollars and would be a far better value proposition and the person in question could always be called upon for aftercare and newer projects.

Its true that many things co-evolved with us, like viruses and blood types(yes, we're somewhat on topic again) and even though we share many similar characteristics, like blood type, mayor, minor. Its also true that discovery of new things doesn't always invalidate the old way of thinking. Usuallyit just adds to what has already been existing. Like how multicellular life is a true breeding ground for single celled organism.

Similarly, the ABO+- blood type system was good enough to not kill patients, which is quite the improvement. Though only a fool would treat that system as gospel and align personalities with it. Now we're classifying the minor types and we're getting closer to rediscovering the uniqueness of everyones blood just as everyones beliefs,god or no god, is unique if you are willing to look.

I know that HN is not very appreciative of religion or god. I'd just like to change someones perspective on that as we've all evolved from very humble beginnings, both in our personal lives and as the silly monkeys we all still sometimes are. I definitely wouldn't want our economy to become a paperclip maximiser but any perceived missteps should be dissected with a good blogpost on how we got here in the first place.

There are 'gods' that are 'better' than others. Even if the principle of what you/people believe goes against what you find scientifically relevent, or factual, or sensible. There still is something to be said about a group of people following a strange set of rules that could be demonstrably better than other sets of rules and beliefs. May it be enviromental, genetic, placebo or a tiny edge over what gives life meaning. We ended up with the gods we have today, not by coincidence, but because all the other ones failed their followers.

The only succesfull human spacecraft that landed on another body and taken off again used a three stage rocket to deliver a three stage lander,

The Command and Service Module(CSM) which brought the two stages into low lunar orbit The Lunar Lander (LM) contained a descent stage and an ascent stage, the descent stage was used as a platform for the ascent stage.

To say that three stage rockets are just for one way missions is silly, especially considering that more stages enable larger payloads. We've yet to see whether SpaceX's two stage solution will actually be any good. I also do not expect a single stage to the surface of the moon and back to Low Lunar Orbit to be very usefull. Any mars mission will likely follow the exact apollo staging plan.

No wonder there's a v2 and v3 with much, much larger fuel tanks and less payload.

Modern pressure vessels can reach 5% empty mass, thats a factor of 20

Rockets have stages, a good approximate is to stage half your rocket to get rid of the most empty mass. This also means your first stage has to have double the thrust to lift itself and its stage. Now you're at a factor of 40 just to hover.

Now you actually have to take off, usually around 1.2 to 1.4 thrust to weight.

So a more realistic scenario means your rocket engine has to throttle down to exactly 2% power while the laval nozzle is optimised for takeoff thrust only.

Foreign aid has always been a double edged sword when it comes to self-reliance and lasting change
