econcon··on Netflix stops charging customers who never watch
It results in more support requests.

For example, often you hear angry customer who is like "can you refund me, I didn't use it this month, you can check your records"

Then request is passed on to some other employee who confirms that they really didn't use their account.

After that you issue refund.

In most cases, you end up issuing refund either way while in some cases customer forgets but he doesn't forget he got charged. So it counts towards negative experience even if a customer didn't complain about it.

If your company is here for long term then every negative experience matters.

econcon··on Ask HN: Ways to generate income when you're at home without pay?
There are companies who sell packaged extruder:

https://www.noztek.com/product/noztek-xcalibur/

The 13k listed machine produces 2kg per hour.

Extruder are heavy and low demand item, even cost of shipping will double the price of the machine which I've made.

econcon··on Facebook to shift permanently toward more remote work after coronavirus
My neighbors son is 3 year old

When I am repairing my car/bike, he comes with his bike (small plastic one) and gets under it and starts repairing act.

And he does it for long as I am repairing mine.

It's interesting that I don't live with him but he is copying my action but when I asked his mom if he helps with housework as he probably sees her doing a lot of housework, she said no.

I've no idea why getting under a bike is more appealing to him than doing stuff like cleaning with a mop and bucket.

I am a hobbyist machinist and I work in software development. Software development for me is good paying but boring work where I feel like I've sold my soul to devil and this has literally sucked all excitement out of my life.

Now that I work from home, I've more time at my hand so I am working on my hobbies which make me more productive at my work.

Yea but OP is trying to help his friend and I am pretty sure they've some friend who might have experience working with mechanical things, maybe they know a mechanical engineer and JV, produce output and turn it into a mini factory, we never know!
econcon··on Ask HN: Ways to generate income when you're at home without pay?
Yes, I know a lot of people who don't have opportunity or have some sort of mental roadblock that makes them not put efforts into area which can potentially produce result. I am not sure if there is some name of this phenomenon.

But usually they need a visionary who can make them believe in the idea and then they can put their work/efforts/mind into it with confidence and they do end up achieving the result at the end.

>Is it really? I've looked into this a good bit myself and it seems that many who have tried this have trouble keeping the diameter consistent.

If you'll check my medium post, I've linked a video where I am extruding filament.

Problem with those hobbyist machines is motor torque/power rating. And second, they don't use a special screw and barrel.

The motor used in professional extruders used in real filament factories starts at 5 horsepower for the smallest machine.

If you miss those two things, there is no way you'll get within 0.03mm

Without any PID feedback loop, I can get within 0.03 by setting puller speed manually.

>I suspect that if it really was trivial, then you'd think just about any commercial supplier could get it right

There is no reason to believe that junk filament is coming from people with good machine design. That could be coming from hobbyist underpowered extruder machines like filaestruder and likes.

>Maybe you are just very good at it; +-0.02 is pretty good even by commercial standards. The entire first page of Amazon best sellers are +-0.03 or +-0.05.

At higher extrusion speed you'll get more output per extruder machine time but you'll have lower filament dimensional stability.

So the trivial part is have a powerful motor, use a good screw+barrel and don't extrude too fast.

That said I've offered my telegram in medium post and YouTube video. So anyone who gets stuck can reach out to me. I am not leaving them hanging on their own.

Also, I am looking to make a microcontroller firmware for extruders which basically measures the filament then sets the puller roller speed based on thickness measured. It pulls filament faster if it's thicker than target and pulls filament slower if filament is coming out to be thinner than expected. This will help us reach 0.0020mm accuracy easily!

The problem I am facing is:

1. I am not good with micro controller and control algorithms

2. Laser guage which measure the filament without distorting it is expensive and starts at 2K USD.

So anyone who can help solve these technical challenges are welcome.

But you might not need this much dimensionally accurate filament. Selling within 0.03mm is easy.

Anything better not sure how much it will help FDM quality but yes microcontroller firmware approach will help get more output out of this machine as biggest problem with extruding too fast is that dimensional stability goes haywire.

There is shortage of 3D printing filament because of virus, so I've been creating filament and selling it.

https://medium.com/endless-filament/make-your-filament-at-ho...

This activity also help recycle waste plastic.

Production cost of filament is $7.5 per 5kg and filament roll has 850 gram filament and can be sold for $20-30 per spool

It's trivial to get the quality right.

You can sell rolls on Amazon, eBay and Etsy or your own Shopify store and use Facebook ads/Google Ads to advertise your website.

econcon··on U.S. Birthrates Fall to Record Low
>-A growing population goes hand-in-hand with a growing economy. This tends to bring prosperity to many people

To have higher GPD US atleast doesn't require more population.

Here is why:

1. American companies sell outside US so we can benefit from selling to India, china and Europe.

2.Even if we aren't exporting to some countries, there is still demand for our currency as they can use it to trade for other things like petroleum

4. Even if we've no petrol or exports, rich people and companies from other countries invest in our treasury bills, bonds and stock market.

Look at how many companies of different countries even like the ones from UK, India and China invest into US market because of its safety

>the Muslim world had plumbing, water filtration, surgery, advanced mathematics, and many more amazing scientific advances

A lot of which came through Indian traders, first evidences of human surgeries are found in Indian subcontinent, Indus valley civilization had pretty advance irrigation system for the time and mathematics: quadratic equations, notion of zero, notion of limits and inifinty were here in philosophical sense even if no one every applied it in mathematics.

In the field of war strategy and material, like steel for sword - India was wayy ahead at its time. They knew about the steel temperament long before Europeans even started using steel for swords.

"During the 6th Century BCE, an Indian physician named Sushruta – widely regarded in India as the 'father of surgery' – wrote one of the world's earliest works on medicine and surgery"

econcon··on A Google Cloud support engineer solves a tough DNS case
Google support is basically non existent for customers even spending like 5-10K a month on their platform.

Even questions you raise on their Reddit sub go unnoticed.

They don't have bunch of people actively trying to solve their customers problem.

That said the only time my problems were actually listed to were from BigQuery team. Other than this, I don't think it's possible to get any explanation on a feature from any other product team at Google cloud.

econcon··on Ask HN: Now we're staying inside with Wi-Fi, have you changed your cell plan?
I am not paying for my cellphone, I see everyone is on WhatsApp already and I call them on WhatsApp.

That said I live in India. I already pay for fiber gigabit connection at home, so spending extra on mobile is not worth it for me.

That said, most of job is done on email/WhatsApp and I rarely need to call anyone.

And if need comes, I'll just recharge my mobile through internet and get it going within 5 minutes.

econcon··on The genuine polymath is still one in a million
He might not actually have discovered or invented everything on his own.

What I most likely think, is that he was more like a Director of a government program or university who's tasked with key projects and allowed to interrogate or gather intelligence from anywhere.

He most likely met a lot of people from both east and west, learned a few things them and decided to document them. Maybe those people also documented it in their own language somewhere but ofc it didn't survive the test of time and only way we know any of those things is through Leonardo's illustrations.

The cities where he lived had influx of traders from all over the world.

It's otherwise seemingly impossible for someone to come up with so many things during his lifetime.

Where I live in India, nearly 90% of the restaurants and hotels get their food from one place at rock bottom price.

And the restaurant/hotel the customer is dealing is responsible for arranging delivery and serving.

econcon··on Neofeudalism: The End of Capitalism?
I live near a lake side villa in India. It's spread in 21000sq feet.

Very sparsely populated.

It has a few shops and hospitals within a kilometre.

Ofc, there is no way I can afford same land in middle of city but a lot of people don't have choice between living in a city Vs living somewhere peaceful / scenic.

Their jobs are in city so they can't just move to somewhere clean and beautiful.

There are things in city which is mostly services available at walking distance.

I am YouTuber - I need the land my channel and also don't really need extra services which city offers.

Once a month, I take the truck to city and hall all the stuff I need for channel.

econcon··on Modern universities are an exercise in insanity (2018)
If all education was free. I would be much willing to study forever.

Here are the benefits of get:

1. Cheap accommodation

2. Access to high tech cutting edge equipment on university premise

3. I'd sleep in fully air conditioned library making excuses that I fell asleep while studying in library.

Access to free internet and machinery/test equipment alone would be enough for me to join free university.

Then I'd study there untill I discover something and rise to fame or find some idea to turn into into a profitable business then exist the university and kiss it goodbye.

econcon··on Modern universities are an exercise in insanity (2018)
People often forget that one of the biggest value of having degree is the optics that comes with it.

Basically if a person has spent time getting a degree this shows a important value - risk averseness.

Another value it shows is - being subservient. You are allowing some professor or institution to have significant control over you well past age 18 as an adult.

Risk averseness shows that you'll not be duping the company or stealing their secrets and starting a new company as a competitor and you prefer having a stable salary than mega payoff by selling the tech of the company where you work.

And being subservient means, you'll listen to all the BS magement wants and also you'll not question the authority or go against them.

One my best friend used to run a top architecture firm and he himself was highschool dropout, he had team of architects and engineers to get his wildest imaginations passed by government's approval.

Case in point, being if you've real value to offer. Absence of that degree or paper will never come in your way.

Missing info is

1. If these guys pay taxes or charge GST on food delivered.

2. How many units they deliver each day

3. What the cost of delivery of each unit and what's the value of the food content?

econcon··on An Airbnb for farmland hits a snag, as farmers raise data privacy concerns
In India big farmers rent their land to big corporations and sit back relax and collect rent dollars.

Many have become millionaire overnight by doing this.

Government started taxing farmers for this reason. Untill recently, all farm income was tax free.

The case in point being that MNCs are producing the kind of output, no farmer here ever could dream of producing.

And the con? All they need is a huge piece of land.

Very little labor if any is used in this.

Most small farms are not profitable as overhead of bringing machine or labor to small farm is just too high.

I know a few farmers who sold their few hectares land in Punjab and brought several thousands of hectare land in Australia.

So you can how inflated the price of farm land is in India.

Now after making enough money in Australia, they are buying back their ancestral lands and this is sending the price of farm land in Punjab through the roof.

econcon··on Amazon is handing out 'Thank you' t-shirts to warehouse workers as it cuts pay
>Let's just say it's not great, but it sounds like you have an axe to grind so we should just leave it here.

It's against HN guidelines. Suggesting ulterior motives behind my comments, is seen as a comment made in bad faith.

Germany has great quality of life because it has managed to ship its underclass to East of Europe.

If you don't believe this is true then why EU doesn't have free trade agreement with China or India? Yea you may suspect that their cheap low quality product will flood local market and outcompete the local producers. But how about high tech producers who have vastly superior technology and productivity flood poor countries with their high quality but cheap to produce products? Is that fine?

All I am saying is, there should be no union and free movement of goods and people between poor country and rich country. When this happens, rich country becomes even richer and poor country does grow a bit but it's upside is limited in long run.

And any farmer in Romania who has sold his land to Automobile companies from Germany can attest to it.

Germany isn't a winner in EU because it's best, it's winner because it started off better. When EU was formed, German producers flooded eastern economies with their mass produced goods and bought out their lands and local companies. The opposite couldn't happen because Eastern producers were technically and capital wise behind.

Unlike others I don't really believe in moral superiority of West European countries the fact that France still gets royalities from Africa (stinks of Imperialism) and Germany cramming Romanian farm laborers by not even offering them "social distancing" reeks of exploitation.

As EU members figure out the con of perpetual poverty trap, they'll walk away from EU.
