It depends on where you are raised.

I need to make deals in cities like New York, or London or Paris, Frankfurt, or Madrid.

At buildings, specially hotels in those cities there is a constant hum, low level noise all the time that is specially present when you need to sleep.

People that are raised in cities are hearing this sound all the time. I was raised outside them so for me this sound is alien but for those people it means "home".

It was incredible being in Paris or Madrid center with COVID and hearing birds as background instead of road sounds.

I need birds or sea waves or tree leaves sounds in order to work and focus. Cars or air blowers sounds are really distracting for me.

Why does it feel like there’s more prose about lisp being written than lisp code? I swear there’s like 15 people writing Common Lisp — Nikodemus, Shirakumo, Stylewarning, Christian Schafmeister, Borodust, the ITA folks, and maybe 2 startups.

That is because it is a little secret. It is a secret hidden in the open.

We program in C#, we program in swift, C and C++, but we continue using so much Lisp as I did 20 years ago or way more.

With Lisp you don't need to write only Lisp, you can write swift or any other language in Lisp, as we do.

When people ask what programming languages we use, even competitors, we just tell them. They don't listen.

They just can't really understand. They probably believe we use Lisp because we depend on obsolete technology because they are under the influence. The influence of snake oil salesman that want to sell them their new shiny language.

For them anything new is shiny and old means dusty because things degrade over time, but computer languages do not.

If competitors can't "get it", much better for us. They probably believe that we try to deceive them and that in reality we are using this new language-paradigm of the week that solves all the problems. Let them.

Lisp guys have nothing to sell you but probably the software they create. And if they have a powerful tool, they are not that interested on you knowing their secret.

What if not all sensor data is accurate or reliable? For example their new cars have no radar and therefore the distance is just an assumption of the AI model and can be wrong. It would be pretty bad to rely on unreliable data for the justice system. If they want to use all data I assume some form of interpretation should be done by the Tesla to avoid false positives or false negatives. Especially in crashes where FSD was driving.

Radar data is also an assumption, way weaker than cameras.

Cars radar sensors are not the F22 ones, they are very simple, limited and it is not the sky in which metallic objects are foreign and there is empty space everywhere.

The world on earth surface is full of metallic objects with very complex shapes and reflections everywhere(and you have military safety standards, my uncle got cancer(and died) after working with military radars as an engineer and working so close to them). My uncle could not prove the connection but if thousands of people start getting cancer after those devices are common it will be much easier to prove.

With cameras you have millions of points array for cheap that lets you differentiate things much better than simple radars do.

Imagine that you integrate all the colors that go in a camera to a single color. That is what you have with radar sensors.

One day, hopefully we'll be rich enough to do this and not have it be a mess. Fullly automated luxury space communism is the goal.

bumbada · 4 years ago

Luxury and communism are opposites.

Compatible words with communism are miserable, corrupt, genocidal or tyrannical. You can pick whatever you want.

> I'm not aware of anywhere that attempts to socialise housing has worked well.

In Vienna about 25% of the total housing stock is public housing[1]. It's the main reason why rental prices are significantly below other European capitals[2].

Not really. The main reason Vienna have rental prices below other European capitals is because it was one of the few cities that actually lost a significant part of its population multiple times. It was the capital of a big empire that was destroyed and they incorporated to a different Empire that also was destroyed.

Lots of people left to other cities that were not as bureaucratic looking for opportunities an oversized capital without Empire could not sustain.

BTW, It was not pretty. Lots of families that used to live in Vienna now live in Israel for a reason.

You could say the same thing about Detroit in the US.

bumbada commented on Ask HN: Do you tell your salary to people/family/friends outside your industry? · Posted by u/tester34

bumbada · 4 years ago

Never. I am from Spain, probably the most envious country in the world.

I never talked about money when I was starting my career(and earning way less than my peers, friends and family) and do not talk about it now that I make much more than them.

In the US people brag all the time with money. People value other people more because they make money and they value you less if you don't make money. People working in the private sector earn much more that people in the public space.

In Spain it is the opposite. Spain today is a socialist State in which public servants earn in average more than 35% than people in the private sector. Everybody wants to be public servant because it is "safe", even when the State is bankrupted and supported by EU deficit that will end sooner than later.

In places like Africa, South America or South Asia talking about the money you have is just dangerous. One of my family members had a cocaine bag planted in her luggage in Thailand by the taxi driver. She noticed and trew that away but the police man in the airport knew exactly the specific place where the bag was and searched for it again and again.

You better be careful because people like your kids used to the West can really be very stupid in those countries, because they are used to things like a Police system that is not corrupt.

I have traveled to many places of the world on my own alone wearing causal clothes and not spending much money that would have been very dangerous if they knew the money that I had in the bank.

Do you know whether anyone using these types of tools (like OpenSCAD, CadQuery) in any serious design? By serious I mean, real, industrial use cases (think automotive, defense, aircraft, etc.). Or are these tools mainly targeting hobbyists?

bumbada · 4 years ago

We use those tools for industrial prototyping because we can program those in things like python.

We use it for creating as crappy designs as fast as possible, not getting designers to premature optimization.

For serious design no, we use expensive commercial software for that, once it is clear what the solution is.

For exploring lots of different spaces cheap 3d printer, cheap CNC milling machines and laser cutters are amazing.

We restrict access to serious software for early prototyping because people will try things like super complex organic shapes that require supports or special milling machines instead of machines that cost 100 less money.

That makes time to market so long and a design a competitor could squash the price when he uses cheap alternatives for manufacturing.

> And the diseases were only a small factor in the outcome of the colonization. Guns being a much larger factor, for example.

I'm not so sure about that. Writing gave a huge advantage to the Western forces. By that I mean military men had access to a couple thousand years of military tactics books. Having advanced weapons is one thing, knowing strategy and tactics is quite another.

For example, there are battles where the Romans were outnumbered 10:1 and still defeated a better armed barbarian army. The Romans were organized, disciplined, and trained to fight as a unit. They would just slaughter the barbarians who fought as individuals.

Remember, guns at the time were muzzle-loading, and had some rube goldberg contraption to light the powder. They were unreliable, inaccurate, and very slow to reload.

bumbada · 4 years ago

People in America were not stupid, there were not repetition guns yet, like Repeating rifle or early machine guns.

The biggest significant factor for Spanish people was getting the support of the local population. It was not foreign powers against local powers. But local powers against local powers.

And that was because local empires were terrible with the subdued tribes. There was human sacrifices with subdued tribes and they were slaves. Under Spanish rule those who supported the Spaniards were soon considered Spanish citizens, a huge improvement.

And Rome usually worked the other way around. Rome did outnumber everybody and squashed any opposition. First they did because mandatory Conscription ("the draft")in the army, an army of peasants that was way more numerous than anybody else and a population that will replace casualties much faster than anybody else.

The Army of peasants did fight against elite warriors that were much better trained and equipped but were way less numerous, for example against the Macedonian Army,and they won.

Finally, after growing and organizing themselves much more, Rome will use infrastructure that only they had like the Mediterranean sea and specially roads to move massive amounts of soldiers very fast from one part of the Empire to another.

This was the equivalent of the train that will make it possible for Germany, Russia or the US moving so much people to the war front fast.

It was the Romans those who did outnumber everybody else concentrating the army at one point, defeating the enemy and moving the Army to another place.

And it was Julius Caesar who wrote "divide et impera" because that was the Roman way of doing things, dividing their enemies, and fighting them isolated with a much bigger army.

Shouldn't one look at genetics as well? When a completely different ethnicity invaded and called themselves Roman, and copied the parts they wanted from Roman civilization, but without having almost any Roman ancestry, are we to consider them a continuation of the Roman civilization?

bumbada · 4 years ago

are we to consider them a continuation of the Roman civilization?

Yes, because being Roman had nothing to do with ethnicity. Even people from Italy were not Romans at first. The Latins people allies of Romans(socii) fought wars to be recognized as fully Romans and only after winning some battles they got it.

In Jesus time only 10% of the population had Roman citizenship, like St Paul, but after some centuries everyone had it.

Something similar happened in the US, black people were certainly not fully Americans or even people at first, they were slaves, let alone native Americans, devoid of any right.

The survivors that were not exterminated(like native Americans) fought for their rights and eventually they got it, after having lots of their houses burned,their women raped and their men murdered. They were sent to World wars in the worst conditions at the most risky positions.

Rome was a way of living, way beyond ethnicity. You only understand it when you travel to places without this heritage, like China or Afghanistan.

When I traveled to China I was surprised to live in a place with no rule of law for example. The Rule is whatever the CCP leaders want today. I took so many things from the West for granted.

If you're living on your boat 365 then I imagine avoiding severe weather becomes more important?

bumbada · 4 years ago

This is the reason Weather reports and forecast are so important for people on boats.

Most people living in boats actually live on ports and don't get very far from the coast most of the time.
