I second this strongly.

Meditation helps me be less reactive to stimulus and also decreases the occurrence of random thoughts.

Think of the human body as an IO system. Your sensory organs constantly giving you inputs from all directions.

Your mind deciding what the output should be.

When you meditate - I feel like you add a latency to your responses which allows you indirectly to focus better.

Second thing that really helps is a non distracting environment (decreasing potential inputs) - have a space where there isn’t much distractions.

Phones with push notifications id say are one of the biggest sources of distractions - I have most notifications switched off and check different messenger/mail apps periodically as I finish blocks of work - this absolutely helps in terms of focus.

I don't think I could sleep to that voice though super interesting as as a concept.

Maybe using some sort of deepfake for voice would make this a 100x better.

That’s true for stocks too.

As people sell, value plummets

That doesn’t make it a Ponzi scheme

So to talk about the killer app we’ve got to differentiate the technology from the first use case, which is digital gold for now

Ethereum goal was to allow people to build different types of dApps by opening up the number of op codes on the virtual machine - this allowed people not only to build bitcoin on ethereum but also other types of apps - like Uniswap (Exchange), Compound (Lending) and dydx (derivatives). These are just a few. There’s a whole other world of NFT’s that is also bubbling up now. Aragon is building a DAO creator and launcher where you can build and run organisations in a digital jurisdiction.

Now as the World Wide Web decentralised the power to distribute information via a protocol, Blockchain’s can allow that for anything that requires trust - such as finance

Though the biggest limiting factor is still scalability of Blockchain’s but the Ethereum team and a bunch of other teams are solving that by being at the breeding edge of mechanism design. Ethereum realised Blockchain’s aren’t scalable and are bad for the climate long long ago - and already have plans to move away from PoW (energy intensive) to PoS (not energy intensive)

P.S - I got into bitcoin early because believe it was a hedge to inflation - realised it isn’t really a value add to society and have been dabbling with ethereum projects since 2016

I get the hate HN has for bitcoin - but deflationary assets are a use case especially when central banks believe they can pump infinite money. Nobody knows where this will end but your best bet is a deflationary asset

I love tech and finance - I believe the next decade we’ll see finance being disrupted by these protocols as ethereum moves to PoS

I agree - both my immunity and energy levels are clearly much better when I do practice Wim Hoff vs when I don't. Though its been only a year and a half or so.

Namecheap is awesome. I switched from godaddy's predatory practices to namecheap, couldn't be happier.

To be honest most providers suck. Another common scam these guys run is skinning you for renewals, its just messed up that sometimes i have to pay double to triple the price of buying the domain for renewals.

There is a caveat that this article doesn't consider.

In India, if you are studying for elite colleges, in this case the IIT's, you write the entrance exam designed specifcally for that, which is IIT-JEE.

Most people go for separate training camps to study for JEE. The 12th grade exams are a cakewalk compared to these exams, and the stuff you study for the JEE is sometimes super advanced, like calculus in super advanced levels.

Most kids studying for JEE ( I was one of them), don't optimize for 12th grade exams because the JEE exam rank is all that matters to get into these "prestigious" institutions.

So a bad 12th grade score is by design more than anything.

Though there is definitely a lot of signaling, the research has ignored a very important behaviour.

What we are seeing is an unprecedent level of supply and demand shock. What this means is that there is going to be much lesser spending and businesses making much lesser money.

If this reflexive loop kicks in people have lesser disposable income and a lot of people will get unemployed ( we can see the early signs in the hospitality and airline industry already)

If this continues, then there will be foreclosures. Asset prices are going to go down. We will enter a recession. If Banks stay alive and liquidity is pumped into the system by the Fed, then we could see a reversal, if the shock persists for longer and finding the vaccine takes more time, we could head towards a depression.

Obviously there are tons of moving parts and there is no way to predict the future, but its likely that we will have a recession. There is a low probability that this will head to a depression because the Fed has been printing loads of money, but if this stops working, they have no more tools in their arsenal to revive the economy.

Fellow Indian here who's been tracking this since Feb.

Highlights of what I think are the biggest risk: The number of tests being performed in India are 20x less than most other countries, though it has ramped up in the past few weeks, there was a free flow of international travel till then.

My fear is that because the virus is asymptomatic, there are a lot of active carriers freely moving around. Most companies in India also find WFH an alien concept, even in tech, so it seems like most people still have to go to work.

I believe that the urban density in India is too high to stop something like this even from a lockdown. Also the lockdown would only help the middle class, there is a large section of urban poor that depend on daily wage that can't stop working. They depend on this money for food and shelter.

Overall, the avalanche is imminent, and I believe that the situation could be dire in the cities.

As tests ramp up the true impact will be seen but I fear that we'll always be behind the curve on this because of the difficulty of mobilizing testing at such scales.

The only way we can avoid large scale impact is if the virus finds it hard to survive in the heat, now that summer is in. Temperatures are rising but there is no consensus on whether that hinders the spread.

Fair, depth perception from 2D isn’t there yet through ML, but mixed with radar can it be effective enough.

The reason I assumed it works is that lidar on the article above seems more like a redundancy. Because their camera system have the short range covered and radar has the long range covered. Lidar seems to augment over it.

Though the order of disengagement is a great stat, that definitely shows how much better waymo is compared to Tesla

That’s a fair point. He does have a bias to sell that story.

I don't have a Tesla nor am I a fanboy. Just talking about the tech.

This is biased information as there are way more Tesla's out there compared to Waymo's.

Waymo has had accidents too https://www.wired.com/story/waymo-crash-self-driving-google-...

That's fair, I've just taken the marketing at face value.

Though I ended the answer at the end asking whether Lidar adds incremental or exponential value? Do you think it adds exponential value ?

I'm not an autonomous car engineer so don't understand the nuances but from whatever basic information I've read it doesn't seem like Lidar's add exponential value.

edit: Just to add, 5 million Waymo miles have been driven with a driver that controls the car and Waymo has had an accident too - https://www.wired.com/story/waymo-crash-self-driving-google-...

Also Waymo has way lesser cars on road than Tesla

It isn't necessary and the best example of this is Tesla's autopilot. It uses no Lidar component and Elon Musk's bet is that self-driving cars can just use just cameras, basic radar and ultrasonic sensors with enough compute resources and the right ML algorithms to perform better than a human.

He's been a long time anti lidar proponent because of the costs involved and the aesthetics. He's also betting that the amount of data Tesla receives from its customers, and the neural net they have can achieve autonomous driving with its current hardware stack.

“In my view, it’s a crutch that will drive companies to a local maximum that they will find very hard to get out of,” Musk said. He added, “Perhaps I am wrong, and I will look like a fool. But I am quite certain that I am not.

"Despite being a fancy and expensive technology, LiDAR provides surprisingly little advantage over a combination of cameras and radar. Radar, for example, is much better in the rain and other limited visibility scenarios, because it is based on radio waves rather than light waves. Radio can penetrate through some objects and bounce back from others, thereby “seeing” the environment along a different dimension."

an excerpt from a quora answer on why the Tesla stack could be better than Lidar: https://www.quora.com/Why-dont-Tesla-cars-use-Lidar-like-mos...

Here's a video of Tesla's autopilot perceives its environment : https://www.youtube.com/watch?v=fKXztwtXaGo and here's a video of how Waymo perceives its environment: https://www.youtube.com/watch?v=OopTOjnD3qY

The question is if the Lidar adds incremental value or exponential value, and I think it's just incremental by looking at those videos.
