Govindaeon Elon Musk’s Neuralink Gets $27M to Build Brain Computers

Q/A system, query results returned as memories. You wouldn't need to read about X, you would just remember that you already know about X.

Govindaeon Tesla's 'long-haul' electric truck aims for 200 to 300 miles on a charge

That... What? If you need to use your customers overhead crane to make a delivery, you will be going out of business fast.

Govindaeon Amazon has as much office space in Seattle as the next 40 biggest employers

Don't worry, if you think people inviting you skiing is some kind of vieled attack, you belong here too.

Govindaeon Sun Flyer, an Electric Trainer Aircraft

But they've only been able to fly since 2016.

Govindaeon Show HN: Idea Generator That Uses YC as Data

Self-driving nuclear reactors and currated wine deliveries for developing countries. Those are definitely ideas.

Govindaeon Alphabet’s hate-fighting AI doesn’t understand hate yet

This is a general NLP problem. People use language in more complicated ways than direct literal encoding. In the general case, it's a very hard problem, but hate specifically may not be so difficult.

People tend not to use phrases like "kill all the" in unambiguous ways.

Govindaeon The Irrationality of Alcoholics Anonymous (2015)

>I'm having a hard time finding where it's suggested in their literature that salvation comes from sobriety?

The message is the opposite. It's sobriety comes through salvation.

1 We admitted we were powerless over alcohol - that our lives had become unmanageable.

2 Came to believe that a Power greater than ourselves could restore us to sanity.

3 Made a decision to turn our will and our lives over to the care of God as we understood Him.

Govindaeon Researchers unravel the biosynthesis of psilocybin

My friend said that pressure cooking popcorn kernels as an incubation medium allowed fast mycillial colonization. He could shake the jars every couple days to speed up the process. He also claimed pasteurized hay made an excellent growth substrate.

Govindaeon A Solution of the P versus NP Problem?

Well... The traveling salesman decision problem, not the general case.

The problem of finding the optimum path is not in NP, if I give you a candidate solution you can't easily check if it's the global optimum.

What is in NP is the decision problem, finding a path that is better than a given bound. If I hand you a candidate solution, you just have to compare the sum of the distances to the bound to check it.

Govindaeon MIT team’s school-bus algorithm could save $5M and 1M bus miles

Oh hey budget space must have an L1 norm. That's neat.

Govindaeon MIT team’s school-bus algorithm could save $5M and 1M bus miles

I suppose they should be talking about budget velcoties.

Govindaeon Why our outdated brains are making us unhappy

Someone must have the most likes. But it's true for the rest of us. If there are disconnected graphs, they'll have a local king of the popularity hill.

Govindaeon Exploring strategies to decarbonize electricity

We have successfully sent robots to Mars, but... I don't really need that light on in the living room.

Govindaeon Ask HN: How to eat and drink properly?

At least since 2005.

Govindaeon SKYACTIV-X: first commercial gasoline engine to use compression ignition

Most gasoline engines are homegenous charge, and run within a few percent of the stoichiometric air fuel ratio. Diesels will run at 6x the stoichiometric ideal amount of air.

Govindaeon Ask HN: How to eat and drink properly?

This is great advice because every additional ingredient you add reduces your risk of colon cancer.

Govindaeon SKYACTIV-X: first commercial gasoline engine to use compression ignition

Yes, but stratified charge combustion produces significantly more NOx in cylinder because of the excess oxygen.

Govindaeon Less Weird Quaternions Using Geometric Algebra

While we all learned in middle school geometric algebra that the even subalgebra of G3 is isomorphic to the quaternions, what is the relationship between the even subalgebra of G4 and the octonions?

If you write out a multiplication table, it seems that it's isomorphic. But... Octonions aren't associtive. Does the even subalgebra of G4 somehow lose associativity? Is it equivalent to Octonions with a cannonical multiplication order?

Govindaeon Less Weird Quaternions Using Geometric Algebra

Do you know what a vector is? Vector:Line == Bivector:Plane

A vector is an oriented (+,-) magnitude(length) _in_ a line. A Bivector is an oriented (+,-) magnitude(area) _in_ a plane.

That area does not have any particular shape.

Govindaeon Less Weird Quaternions Using Geometric Algebra

That doesn't work, the odd space isn't closed.

xx = 1

Govindaeon Not even wrong: Why does nobody like pilot-wave theory? [pdf]

Any randomness could in principle be predetermined. God could have rolled the dice ahead of time.

Govindaeon Grasping Robots Compete to Rule Amazon’s Warehouses

I've seen AI learn to walk in simulation, I've never seen one learn to tie a shoe.

Govindaeon Hidden surprises in the Bitcoin blockchain and how they are stored (2014)

There's a new block every X minutes. Where's the exponential growth?

Govindaeon Race to discover Planet Nine using astronomy and new computational techniques

That effect decreases further out in the gravity well.

Govindaeon 3D metal printing is about to go mainstream

They would need to be able to create a powder with consistent grain size.

Govindaeon A living programmable biocomputing device based on RNA

https://www.sciencedaily.com/releases/2015/12/151216151617.h...

Some earlier work in the area, it's just an AND gate, but it demonstrates an application.

Molecules A and B correlate with a psoriasis flare up, molecule C is a psoriasis medication. If A and B are present, the bacteria produces molecule C.

Govindaeon Manipulate Functions with the J Language

'2+34' is unambiguously different from '43+2' (the former evaluates to 14 while the latter is 24)

I really hope the markdown has mangled this.

Govindaeon Bollinger B1: An electric truck with 360HP and up to 200 mile range

A 70mph crash doesn't necessarily involve an unsurvivable impulse. Most accidents are not of the vehicle plows into immovable object sort.

Govindaeon Kerbal Space Oddities

My first interest in programing, outside of the simple office automation scripting I was doing, started when I built an orbital rendevous calculator in KSP (back before they had orbit planning built in).

I eventually merged my mod into mechjeb, adding a whole slew of orbital calculation functions, and many fun space times were had by all.

Govindaeon SpaceX Is Now One of the World’s Most Valuable Privately Held Companies

They are the only direct competitor on technology development. In 10 years, BO aims to be flying reusable rockets larger than the Falcon 9. You can't say that about and other company (except for SpaceX).

They are more directly a competitor for talent. Rocket engineering is a small world.
