My understanding is that this is the way fermions are treated in any modern theory of quantum gravity, and not specific to LQG?
ls-lah_33 · a year ago
Not sure what you mean, are you talking about ER = EPR? I think that's mostly a way of accounting for entanglement between particles, but it doesn't create the particles to begin with like in LQG. But my string theory knowledge is probably out of date, so I could be wrong.

I'm surprised Sabine doesn't mention the way fermions are treated in Loop Quantum Gravity [1][2]. My understanding is they are treated as "non-local" or open loops of gravitational force, and thus entry and exit points in space-time. This makes them conceptually similar to the "wormhole model" of matter that Einstein and Rosen originally described.

This comment is a bit surprising to me. Your point seems to be that strong policies which impose significant good will face significant resistance and so there's no point doing them.

I don't think that makes any sense. Workers rights, regulations around dumping waste, capital gains taxes... There are a lot of things that we already have which some people with power have a strong incentive to remove. We had to fight to implement and to keep these, but goddamnit is it worth it!

I don't see why we shouldn't be optimistic here because historically speaking things have gotten much much better! To me, a gradual and consistent ramping up lvt would be probably the most progressive policy a country could pass at this point :D

This is probably more feasible than you think. A hybrid or split rate combining both land and property taxes is not only possible but apparently exists in practice in some cities, for example Pittsburgh.

Good for them.

There have been some awful stories about how difficult -- and sometimes traumatic -- the content moderation work can be.

When content moderation of really nasty stuff is necessary, people doing it should be getting proper safeguards, care, compensation, and respect.

Worth noting that the company they work for is called Sama, which if I'm not mistaken, derives its name from the word 'equal' in Sanskrit.

I've been paying for a lot of things for my friends recently as there is a very large imbalance in wealth between us which is more recent.

These are my best friends for the 20 years, same gang and they would never ask anything of me and always offered to contribute.

I still felt sort of akward about how I was approaching it. Even if we tell each other everything and are transparent about money.

I wanted to let them know that I don't care about the money at all, it's just the experiences that it will allow that matter to me and giving back to family and friends makes me feel good.

However I have started just acting more normally and not insisting on taking care of everything,I think people feel better this way.

So this article frames it nicely for the things I will be able to contribute still in a way that makes sense.

I imagine that for people with newer or less strong friendships it must be even harder to manage.

Bible time!

In my experience rich people are very 'outcomes focused'. They almost always expect something in return. I always ask myself why are they giving food to me specifically and not just some random person?

Europe dug itself deep into a hole.

At first, we missed the internet. Because of way too much regulation.

Then we found ourselves using only US software and digital services.

What did we do? We created more regulation. Way more regulation. Burying all hope Europe could ever get a foot in the door of the internet.

Now we are about to miss AI.

OpenAI, Microsoft, Google, Meta, Tesla, NVIDIA .. all AI players are in the US again.

I don't think more governmental intervention is the right way.

In fact, I think it is counterproductive.

What should we do?

Well, it's a long process. We would have to get to a mindset that gives small entrepreneurs more freedom. Less bureaucracy and less regulation, step by step. I don't think it will happen. The reaction in Europe is always "more regulation". The thought of removing some regulation is probably terrifying to our leaders.

Don't know about regulation, but the development of the internet was initially subsidised by the US government [1]. AI research has also been subsidised in the past. The famous MNIST handwriting dataset being a good example here [2].

> Objects demonstrating extreme capabilities routinely fly over our military facilities and training ranges. We don’t know what they are, and we are unable to mitigate their presence.

Occams Razor suggests that if these objects appear almost exclusively over US military facilities and US military training ranges, they're most likely operated by the US military.

(Sorry to the Navy pilot whose security clearance is too low to be in on the secret.)

I really like postgres, but I'm starting to wonder if some of these articles are GPT or not.
ls-lah_33 · 3 years ago
Good to see I'm not the first one to notice. Some of the author's points are super vague:

> Use Postgres for caching instead of Redis with UNLOGGED tables and TEXT as a JSON data type.

> Use Postgres as a message queue with SKIP LOCKED instead of Kafka (if you only need a message queue).

I'm sure if we try hard enough we could find some sort of meaning in these points, but then the content is coming from the reader not the author.

Also from the author's mastodon:

As someone who grew up and went to uni in SA, then later emigrated to NZ (and later Europe) in 2007, this is completely expected.

My understanding is that what happened is, in 1994 when the Apartheid government handed over power to the ANC, basically everything the government had in the pipeline was scrapped; of course it was in many ways an evil government, but it was also a surprisingly competent one, the only government to produce nuclear weapons and decide on their own to dismantle them or something? So anyway, all their plans for much-needed energy infrastructure upgrades were scrapped in 1994, and never considered again until the rolling blackouts started, by which time it was far too late. Since then the nearly universal corruption within the ANC and overall state capture meant things rapidly got worse, not better.

I distinctly remember writing code to do periodic saves of a long running computation's state, because the power would just randomly go out, and at one point the power went out while saving the state, so I switched to saving A/B alternating state files.

Most of my family is still hanging out in SA and things just get worse and worse... don't even get me started on the crime...

It's worth noting that under the Apartheid government energy in SA was completely dependant on the state [1]. Then towards the end of Apartheid, due to sanctions - among other things, the government basically had to default on its debt causing the national currency, the Rand, to go into a bit of a tail-spin. To cover their expenses the old government took out a loan from the IMF just before handing over power [2]. These loans often come with commitments to reduce government expenditure, amounting to basically an austerity programme.

I assume that is one of the main reasons that many of the promises of both the old government and the incoming ANC had to be scraped and replaced with essentially what amounted to series of austerity measures [3]. In 2020 the government once again took on a loan from the IMF, again with austerity conditions attached... and here we are, with a vaguely stable currency but a gradually failing economy.

[1] I assume as basically a subsidy for the mining sector.
