pedro_hab··on I accidentally saved my company half a million dollars
I had a friend in a similar situation, he explained the issue and how he would fix it.

I was baffled and urged him to be careful and assume he was wrong that it had to be wrong.

Anyways, he is still fixing it, getting some people to validate it.

I would think he will save at least hundreds of thousands a year.

But seriously, why a company that spends millions of dollars in an area would not hire an expert to try to save some money in it is beyond me.

pedro_hab··on The Distribution of Users’ Computer Skills: Worse Than You Think (2016)
I wouldn't be surprised if it got worse.

Most people are on phones now, who uses computers if not for work?

But I guess one could argue using phones would be the same, but even then my personal experience is that most people don't know much about phones either.

pedro_hab··on Monster gravitational waves spotted for first time
I just posted another PBS Spacetime video answering another question.

I feel like a quasi-expert on these subjects because of it. lol

pedro_hab··on Monster gravitational waves spotted for first time
Mathematically yes, actually probably not.

I'd suggest looking into Alcubierre Warp Drive, cool story on why the guy came up with it and shows how to wrap spacetime around a spaceship to make it go faster than light.

The ship wouldn't go faster than light because it wouldn't move at all, the spacetime around it would.

The channel below has quite a few other videos on the subject. I love it.

pedro_hab··on User In Yer Face, a worst-practise UI experiment (2018)
The pw really stressed me, I checked the source code to find what a valid pw looked like.

Pretty cool code btw, it has a rule array that with the error msgs, very easy to follow even tho it was webpacky.

Then I realized the errors were displayed at the bottom of the page.

pedro_hab··on Mullvad VPN was subject to a search warrant – customer data not compromised
I don't understand why go after the VPN, I think most people don't use a VPN correctly.

What good is a VPN when multiple apps on your computer are phoning home?

If the law has a suspect IP, couldn't they just ask google, microsoft and facebook what accounts were accessed with that IP?

To use a VPN correctly wouldn't have to use a fresh OS and absolutely not login to any accounts connected to the IP you are trying to hide?

pedro_hab··on ChatPDF – Chat with Any PDF
This was pretty bad for me, I tried asking the name of a person references in the PDF and it couldn't find it. I asked who is the claimant in this PDF and it said the claimant was empty.

But if I asked if the claimant name was in the PDF it answered yes.

I am assuming the PDF to Text is not working great here, which I supposed is the whole point.

pedro_hab··on Medium bans user for Chrome extension that opened articles in incognito mode
He probably wrote an medium article on it. lol
pedro_hab··on FX swap debt a $80T 'blind spot', global regulator says
I agree with your point here, but I am curious if there isn't space for people to gamble and not be hedged? Speculating naked with the contracts.
pedro_hab··on The factory that only builds white Toyota Land Cruisers
I wonder if the lower emissions are really worth it if the car breaks down sooner.

All the electronics and gimmicks to lower immediate emissions at the cost of reliability.

My car, for instance, turns off the engine when stopped, that can't be good for the engine and battery.

If saves a bit of gas but I am sure I'll have to change my battery sooner, not to mention the wear and tear on other components.

pedro_hab··on WhatsApp Remote Code Execution in Video Call
yes, WhatsApp used to be great in this regard, you would not get any spam.

Now it's starting to get worse and worse.

I block SMS notifications since I only get spam there (I'm Brazilian, SMS is basically dead here)

pedro_hab··on The Ethereum merge is done
I think this is nice, it forces people that want to participate to have skin in the game.

With proof of work there is incentive for people not invested in crypto to mine as much as possible and sell everything.

If a big enough computer is created, someone not interested in crypto can take money away from it, or if the computer is big enough even destroy it, a quantum computer for instance, should make a 51% attack on a network as proof it is a quantum computer.

I know it is unlikely, I myself think is impossible. But the incentive is there.

With proof of stake there is no incentive to do it, a 51% attack is idiotic since you have to buy so much.

pedro_hab··on How normal am I?
It got a lot correctly about me, and put me at 92% normal.

I wonder if you are too far off "normal" it won't recognize you correctly, eg age.

It seems to be down rn

pedro_hab··on The hunt for the M1’s neural engine
As a developer I am bit ashamed of this question, but I gotta ask:

What consumer apps actually use Neural Engines?

I think something like Photoshop, maybe. But wouldn't it just train a model and use it as regular code?

I'm interested in AI, but it's a joke to me about startups and jargon more often than not.

I feels weird to add this to all chips when I can't see that much usage.

pedro_hab··on Research suggests that when the rich bank, the rest borrow
Can you give an example of a country that archived economic prosperity using leftist policies?

I also find your comment on republicans quite wrong, since I don't see many differences between republicans vs democrats.

Both have been running ever increasing deficits, each president tops all previous presidents combined.

You can't really say any of the US policies have liberal.

pedro_hab··on Research suggests that when the rich bank, the rest borrow
No it isn't, the FED is buying mortgages and treasuries to keep the rates from rising.

How can you say rates would be higher absent the FED buying it?

Rates aren't negative nominally, but they are negative taking inflation into account.

pedro_hab··on Research suggests that when the rich bank, the rest borrow
We don't seem to have houses for everyone, people gotta work and produce to earn a house.

If you start giving mortgages with artificially low interest rates, people who haven't produced things to offset their consumption will get houses, which will increase the prices.

Of course a lot of other factors play roles into this.

> It’s hard to blame people for wanting a roof over their heads.

I, in turn, find your statement quite naive, it would be great if everyone had a house, that doesn't mean we should just give it them, there are consequences, the prices will rise.

pedro_hab··on Research suggests that when the rich bank, the rest borrow
Yeah, the government also artificially suppresses interest rates, making it easier to get mortgages yet somehow the blame goes to the lenders.
pedro_hab··on Don't Pick Up: Missed calls in India
In Brazil there is a 3 second delay before calls start charging. [1]

So we would call multiple times, speaking fast during the first 3 seconds then hanging up.

Then they blocked it, after 10 3 sec calls calls and you couldn't make calls for a while.

pedro_hab··on Meat consumption and risk of 25 conditions: outcome-wide analyses of 475K people
They have a "Role of BMI" section which strengthens your point.

> BMI accounted for a substantial proportion

In the "Role of BMI" they also say that BMI isn't perfect to detect adiposity, suggesting even further that being fat is what you want to avoid.

> Finally, given the observational nature of this study, it is possible that there is still unmeasured confounding, residual confounding, and reverse causality.

Studying human diets is hard.

pedro_hab··on Prosperity comes at 'devastating' cost to nature
This isn't true at the moment, it could be in the future.

Less people die because of nature disasters and such today that they did 100 years ago.

Technology and medicine helps us, they would, without a doubt, be better off with technology than they do without it.

pedro_hab··on Prosperity comes at 'devastating' cost to nature
Yeah, they think its great to live in the jungle, seeing every other newborn dying, just cus your carbon footprint is low.

They couldn't care less for those forgotten children.

pedro_hab··on Prosperity comes at 'devastating' cost to nature
Nature, they are vulnerable to nature.

They could use cars, ambulances, hospitals and etc.

Nature is brutal, always has been, no one lives on harmony with it.

Look at the indigenous peoples death rate, child mortality.

pedro_hab··on Prosperity comes at 'devastating' cost to nature
Yes! A lot of people don't even have access to electricity, even more don't use as much because of the price.

We would need to be using way more fossil fuels / nuclear to have more equality.

This idea to reduce our impact in nature forgets the most vulnerable, which could use some impact in nature in order to have more prosperity.

Well, this is all way easier said than done.

pedro_hab··on NES.css – NES-Style CSS Framework
The fonts render badly on Chrome + Mac + a 27" 1080p

It's a low res monitor, but that font was supposed to be bulky, rendering on a low res monitor shouldn't look soft.

pedro_hab··on Bill and Melinda Gates: America’s Top Farmland Owner
In 2010, expenditures on energy totaled over US$6 trillion, or about 10% of the world gross domestic product (GDP).

58T is the opposite of pretty reasonable.

Even if you could assume it wouldn't need any maintenance, which you can't, it's too much money for anything.

pedro_hab··on Bill and Melinda Gates: America’s Top Farmland Owner
I wouldn't call it small, I'd call impractical at best.

If thats small, how can you describe the size of nuclear power plants required to do the same job?

And power plants would be way smaller and aren't impractical.

pedro_hab··on iPhone 12 Pro so costly in India, you can fly to Dubai to buy it and save money
Same in Brazil, here the import taxes are crazy, coupled with regular taxes it amounts to 100% (doubling the price).

In the case of the iPhone you might need to find a cheap flight to the US, but a Macbook will land you a couple days in Disney.

pedro_hab··on The ballooning money supply may be the key to unlocking inflation in the U.S.
I think we agree on the point, but disagree in the definitions.

Money supply inflation might not directly influence price inflation, though we see price inflation in asset prices, such as stocks and properties.

My point is more on the government saying it needs inflation, when even without price increases inflation might be happening.

We have increasing productivity, cost has been falling, so if prices stay fixed, therefore no price inflation, the people are still paying more than they should.

The value of things have been falling, but prices haven't.

pedro_hab··on The ballooning money supply may be the key to unlocking inflation in the U.S.
I didn't define as I want to, I pointed to the fact that the meaning in old dictionaries used to be increase in money supply.

My point doesn't depend on this tho, measuring inflation by rising prices isn't ideal, because you will be measuring multiple things at once, and only the people lose in that case.

Prices can rise and fall for multiple reasons, and knowing why helps to fix it.

If the price goes up because of a shortage, the increase in price helps stimulate more production.

Governments get the advantage of being able to inflate the money supply to the point were it prevents prices from falling, ensuring easier reelection at the price of the people paying more for things and effectively taxing savers.
