blackrock··on Who Is Still Buying VHS Tapes?
I despise Blu-ray for this. Why must I be forced to watch a stupid 5 minute ad, for the movie that I purchased, every time I insert the disc in?

I gave up on it, and went back to DVD.

Plot twist: China is just goading the United States into spending another shit ton of money into stupid vanity space projects.

All China has to say, is that they’re going to put the first Chinese woman on the moon by 2029. Then the American politicians will go apeshit and say that they must beat the commies. “How dare these bat-eating orientals try to outdo us? We’re going to show them what capitalism and white privilege means to the world!”

Btw, what the fck is an oriental? Who uses that anymore? Apparently, a lot of racist white people still uses that term. And Senator John McCain kept calling Asian people “gooks” until they day he croaked. What a scumbag.

Then the USA goes and spends another $500 billion on this Artemis and Lunar Gateway missions. Money that they don’t have, so the Fed will just have to print more money to sustain the national credit card.

Whether the project succeeds or not, is irrelevant, as the moon missions really adds no further strategic advantage to the United States. And all the allied partners are just leeching off America’s money printing, to say that they’re also lunar partners with NASA.

Meanwhile, America keeps spending big on their military. They keep sailing warships and aircraft carriers up and down China’s coastline as a big fck you to the Chinese.

Meanwhile, Texas freezes to death. Oregon is starving to death. The national minimum wage is still $8.50, because Joe can’t give the poor people a raise. Infrastructure is crumbling. Young adults have crippling student loan debt. Millennials can’t afford a house, and can’t afford to start a family.

Then 2029 rolls around, and China say: “Naw America, we were just fcking with you. We were just trolling you when we said we were going to put a Chinese woman on the moon. We didn’t think you’d actually believe us. Thanks for the LOLz btw.”

America goes: “Dude, wtf?”

So.. invent faster than light travel, go to a distant planet rotating around a distant star, to find a bunch of friendly advanced aliens, that will bequeath us some advanced teleportation technology?

Energy is the baseline fundamental for everything. Wars have been fought for this precious resource.

Currently we get it from fossil fuels, which is running out, heavily pollutes, and destroys the natural ecosystem. Nuclear was discovered, but it’s super complicated to handle and radioactive. Renewables are hit and miss, and must require a massive energy storage system in battery or water storage potential energy. Solar doesn’t always shine. Wind doesn’t always blow.

But in space, energy is infinite. For as far as we can see.

The problem is getting up there, and bringing it back down to earth.

But, what if we can harness it? In the form of solar collectors, and beam it back down to earth as microwaves or lasers. We can have vast fields of microwave collectors that can convert this energy back into electricity. Or laser receptors that can convert the laser back into electricity. No more pollution. No more environmental degradation. What you get is pure, clean, energy. All year round, day or night, rain or snow.

The challenges are great. The impossibilities are high. But the consequences of not achieving this is far worse.

Perhaps we can focus on quantum teleportation instead?

Solve that first, and then we can easily quantum teleport ourselves to anywhere in the solar system. Then reconstitute ourselves at the destination point. And hopefully your device didn’t make a quantum error during the rematerialization process.

You’d have to send the complement quantum teleportation receiver device to Mars, and set it up there first.

Then the device would have to rematerialize you back into fleshy form from pure quantum information residing in your quantum storage buffer.

Oh and make sure that a fly doesn’t enter the quantum teleportation device with you, as you initially get quantum scanned and dematerialized from Earth.

And you must enter the quantum teleportation device without any extra external clothing on. Since version 1 of the device has difficulty differentiating between organic and inorganic materials.

How exactly would you use a nuclear reactor in space to melt stuff? I assume it would be indirectly right?

On earth, the nuclear reactors are radioactive rods that heats up water, to create steam, to spin a turbine, to create electricity. This is like a 5 stage process to indirectly generate electricity. But all the intermediary products are now radioactive.

So in space, I assume you can use the same steps to generate electricity, and then use the electricity to run a furnace, to heat up the minerals to melt it into pure metals.

Or is there some other process of using the nuclear radiation directly in space?

It’s not the destination, but the journey.

Mining for He3 would require all kinds of new technology to be invented. And necessity is the mother of all inventions.

That must be a giant rock that you must carve an internal loop out of.

And then, how much energy would it even take to spin such a huge rock? I think you’d need a new exotic propulsion system just to rotate it. Maybe nuclear or a sustained ion propulsion.

How old are you now? Or what age group are you in now?

It seems like businesses want the expertise of a 20+ veteran, but want to hire 18 year olds, so they can pay them less, and dangle silly trinkets like free cafeteria food in front of them.

Oh and, why is it taking so long to work on it?

A lot of people seem to just create YouTube videos of their woodworking skills. Building drawers, cabinets, anything. They just drone away at it, but because it’s so visual, and you get a cacophony of random noises, that it makes for a good YouTube candidate.

Maybe you can segue into that?

Or maybe you can build and test drones. And the noise from the spinning propellers adds to the mystique of robotics development.

blackrock··on The Object-Oriented Amiga Exec (1991)
Is Dynamic Dispatching supposed to be the holy grail of OOP per Smalltalk’s ideal design of message passing?

An example of Dynamic Dispatch, is say you create a Class object of a person. And you give that object the method ‘jump’.

Then, you create say 30 persons, one for each student in your classroom. Then, you collect them all into a list. And you iterate through that list, and tell each person to jump.

So in Python, it might be something like:

  John = Person()
  Jane = Person()
  # then create 30 of them students
  student_list = []
  student_list.extend([John, Jane, ...])

  # Then make them all jump. 
  for kid in student_list:
    kid.jump()
So, per my understanding this is what Dynamic Dispatch is. It allows you to reassign a variable to an existing set of objects, and to massively activate all of them. Such that, you’re sending an execute command to all of the associated objects.

Was this the genius innovation to OOP, as opposed to procedural languages before it? And can something like this be simulated in other imperative or functional type of programming languages?

This would actually be ideal for a 1-person business. If you pay $25/year, then the guy only needs to find 10,000 people, to make $250,000/year. Not a bad salary.

Now, the question is, what type of SaaS service can you make, to find 10,000 people paying $25/year. One that hasn’t already been consumed by the big players.

If you don’t use Django’s ORM or SQLAlchemy’s ORM, then do you really need to use Django?

Like an adjacent commenter said, ORM is ok for simple blog websites. But I can’t imagine using an ORM for complex data tables and relationships with normalized data.

This reminds me of that hypnotic phrase from the 12 Monkeys tv series.

Anyways, whatever happened to these types of games? Did it just die out as computers got more powerful, and everyone just played first-person shooters or 3d role playing games?

blackrock··on Ask HN: Advice for finding an entry-level remote job?
Not exactly. QA is all about breaking shit.

It’s already assumed that the product has certain features. And that those features work a certain way. But what if you did something else, that was unexpected. Then does it break the system?

As a QA Engineer, your job is to find that fault, and break it. Because you are possibly the last line of defense, before that software goes out into the real world.

Anyone here sell puts on stocks?

Instead of buying into the market, at these inflated prices, and trying to time it, then perhaps sell puts instead.

Collect the premiums as cash in your pockets. And if it the stock falls, then you get to buy it at a much cheaper price.
