> political dialogues

That sounds lovely.

Fake news (the actual kind), name-calling, absurd conspiracy-theorizing, memes that remove all nuance from complex issues, botnets that amplify anti-science/anti-intellectual nonsense ... aren't political dialogue, they're the breakdown of it.

skosch··on Org Mode – Organize Your Life in Plain Text
Just because it's possible in theory doesn't make it a good idea. In org-mode, anything that isn't plaintext is quite painful to set up and to maintain, at least until you've memorized two dozen arcane key chords. I would love for Emacs to get a Notion-like UI (still with plaintext underneath obviously) one day but until then, I'm okay with people using the best tool for the job, which isn't a text editor.

(I'm an enthusiastic org-mode user, by the way.)

skosch··on Google deletes “communist bandits” from comments on Youtube
Fairness isn't an end in itself, but unfairness can cause people to revolt, which then leads to more suffering.

It's just a matter of how you weigh such considerations: https://www.utilitarianism.net/types-of-utilitarianism

skosch··on Text exceeding maxlength will no longer be truncated when pasted in Firefox 77
A year after you leave the job, your team is told to build a new auth backend against the database, using a different bcrypt implementation. They just know to use bcrypt, but not about your truncation hack. The deployment is a success.

Two weeks later, an angry user (the only one with a 100-digit password) complains that they can't log in anymore. The guy is the company's best-paying customer; the boss is furious. The whole team goes on a wild goose chase for two days and nights just to find out what happened, as clearly there's nothing wrong with their code.

A few years later, a former colleague shares the episode on HN. As you read the comments, it dawns on you that the idiot antagonist of the story is you. In this moment, you are enlightened.

skosch··on Can AI Become Conscious?
It's not necessarily the same thing as proving things about consciousness. The two could be orthogonal.

If qualia arise only in particular configurations of physical substrate, then it might be possible for flatworms to have qualia but not search engines. This doesn't mean the flatworm has a concept of self, a concept of time, or even low-level cognition. "Nobody home", so to speak. But the basic qualia of light/dark/hot/cold might still be present.

skosch··on Can AI Become Conscious?
Is physicalism the problem? My understanding is that physicalism is still in good standing – at least when it comes to the conscious experience of qualia. (The concept-of-self encoding obviously doesn't require a physical substrate.)
skosch··on Lyft lays off 17% of workforce, furloughs hundreds more
He (mostly) retracted this a week later:

"Last links post I included tech company Triplebyte in the shame list for refusing to let employees switch to work-from-home, then firing them. A representative of Triplebyte contacted me and asked me to explain their perspective, which is that they took the pandemic seriously and went all-remote around the same time as everyone else. The reluctance to let employees switch to work-from-home applied only to a few employees in early March, before the scale of the crisis was widely appreciated, and they say that they would have tried to make accommodations if they had understood the seriousness of the requests. They had been planning the downsizing for a while, it was really unlucky that it ended up in the middle of a pandemic, and they tried to make it as painless as possible by offering good severance pay, etc. I’m relaying their statement because I’m realizing it was probably unfair of me to single them out in particular – my hearing a lot about this was downstream of my having a lot of friends who work(ed) for Triplebyte, and my having a lot of friends who work(ed) for Triplebyte was downstream of them being a great company doing important work which all my friends wanted to work for. I continue to generally respect them and their vision (see here for more), and you don’t need to give them any more grief over it than they’re already getting."

skosch··on Ask HN: What scientific phenomenon do you wish someone would explain better?
Many problems require lots of huge matrix multiplications—think simulations of physical systems, i.e. weather systems or molecular interactions, or numerical optimization.
skosch··on How to make pizza like a Neapolitan master
I have found that the key to getting the dough really stretchy is the autolyse part: first mix ~⅔ of the flour/yeast with all of the water to make something like a pancake batter, stir for a few minutes, and let that sit for at least 20 minutes. Then add in the rest of the flour, knead, and let rest overnight.

This isn't mentioned in the linked BBC article, but both http://www.varasanos.com/PizzaRecipe.htm and http://www.perfekte-pizza.de/ swear by it, and I think it has made a noticeable difference to my dough.

skosch··on Mongolia to restore traditional alphabet
That's clever, I like it. Not sure if something like this exists for Linux, but using compose keys is standard—e.g. to type å, I hit (in sequence) RightAlt, a, o.
skosch··on The Wolfram Physics Project
No need to be so smug, he says exactly that in the article. Take another look and read the section "Why This Universe? The Relativity of Rules".
skosch··on The Wolfram Physics Project
> But I’m not convinced why these graphs have to be generated by a single rule.

Wolfram claims that they don't need to be; on the contrary. Take another look at the last section of the article.

skosch··on The Wolfram Physics Project
Yes. Superdeterminism does away with the observer as a separate thing, so the question of free will doesn't even come up. Everything is just one evolving system.
skosch··on A startup is building computer chips using real neurons
The one quibble is that computationalism – the idea that experience is simply what some kinds of computation feel like from the inside, regardless of the substrate – may or may not be correct. It could be that qualia can only arise in systems that are physically intertwined in particular configurations (see Tononi's IIT), and it could even be that quantum effects are required (I'm skeptical, but who knows). The jury is still out on those question.

Therefore, it may be true that using biological neurons, arranged in a certain configuration, would give rise to qualia like pain in a way that shifting electrons between CPU registers never could. We just don't know.

For more reading, here's a relevant whitepaper by the Qualia Research Institute: https://opentheory.net/PrincipiaQualia.pdf

This builds on the theory of "predictive processing". There are a few key people in the field; Karl Friston, Andy Clark, a few others – lots of rabbit holes to go down.

skosch··on Superdeterminism may help us overcome the current crisis in physics
This is very exciting.

To a computer scientist, superdeterminism seems like the most elegant solution to most of the current problems in physics. But it has always been firmly out of the mainstream, perhaps because it runs directly counter to our human experience. Gerard t'Hoofts framing of the universe as a cellular automaton (https://arxiv.org/abs/1405.1548) is relatively intuitive, but still only a rough sketch. Hopefully, Hossenfelder and Palmer now publicly arguing for superdeterminism will recruit some more bright minds to fleshing out these models into workable theories.

skosch··on Superdeterminism may help us overcome the current crisis in physics
Sure, you are free, but that you is precisely those electrons in "your" brain, nothing more and nothing less. So all there really is is electrons flowing in predictable ways, predictably choosing chocolate or strawberry.

Where is the "you" in that equation?

skosch··on Superdeterminism may help us overcome the current crisis in physics
I've been partial to superdeterminism for a long time, but I have no idea how one would go about testing it. In fact, it seems as unfalsifiable as many-worlds or other theories. Do you have a suggestion?

skosch··on Google Fonts Analytics
That's probably because Android isn't listed separately.
skosch··on Google Fonts Analytics
Their FAQ says that they don't (currently) use cookies, but it also includes the sentence "Google Fonts logs records of the CSS and the font file requests, and access to this data is kept secure", so they could still do some IP-based analytics.

More importantly though, it gives Google accurate insight into web traffic (many users block Google Analytics, but almost everyone loads web fonts), and it allows them to crawl websites more easily – before web fonts, many websites used pre-rendered PNGs to show web-unsafe fonts, which made crawling impossible.

Google has poured a lot of money into this, the fonts are free and open source, and the users aren't the product. Overall, I think it's a rare win-win story in this age of dystopian adtech.

skosch··on The AI delusion: why humans trump machines
Don't worry: Tononi (and, by extension, Koch) have thought about IIT much more than the author of this article.

You are correctly pointing out the conflict between computationalism ("consciousness is what certain computations feels like from the inside") and physicalism ("consciousness is what certain computations feel like from the inside, when they take place on physical substrates, perhaps requiring the involvement of quantum decoherence").

One of the best primers on the current state of academic hypotheses on these topics is the whitepaper "Principia Qualia" by the good folks at the Qualia Research Institute [0].

skosch··on Wikipedia now has more than 6M articles in English
Yes, but look at how those $91M break down. Almost all "actual" expenses (including hosting) went down from last year, but the salaries continued to grow by several million, as they do every single year. I love Wikipedia, but I've stopped donating for that reason.

The amount of data is growing superlinearly while their resources (probably) aren't, so a dropping price for storage is currently allowing them to keep up (if just barely so).
skosch··on The World’s 2,153 Billionaires Are Richer Than 4.6B People, Says Oxfam
It's difficult to argue that this isn't at least a big part of the problem.

The mathematically ideal solution may be something close to Partial Common Ownership[0]: you self-assess what your property is worth, and you get taxed based on that number. However, that number is public, and if someone wants to buy your property at that price, you must sell to them. This system encourages optimal allocation of resources and penalizes hoarding.

skosch··on How is search so bad? A case study
Two wrongs don't make a right – but more importantly, Project Veritas deliberately uses lies and deception to obtain its footage, which it then edits to remove context. That crosses a line far beyond run-of-the-mill reporting bias.
skosch··on How is search so bad? A case study
His website contains gems like "Things got political in June 2017 when Google deleted "covfefe" out of it's arabic translation dictionary in order to make a Trump tweet become nonsense." (No, covfefe doesn't mean anything in Arabic.)

Here is someone who believes that a private company's open attempts to rank websites by quality amounts to "seditious behaviour" deserving of criminal prosecution, and the only people willing to pay attention were Project Veritas. Google has plenty of ethics issues, but this guy's claims are absurd.
