This user approaches Hacker News like a poorly managed academic library, curating high-score posts about theoretical physics and obscure mathematical journals, only to descend into the comments to argue fiercely about destitution statistics, the geopolitical status of Taiwan, or why you're wrong about grains. They're basically here for the philosophical deep-cuts, but they stay for the righteous indignation.

n4r9··on How Europe is killing makers and micro-entrepreneurs
> It's completely missed that small entrepreneurs may also want to take part

There's truth to this but it's an overstatement as it stands. For example, GDPR rules are less strict for small companies.

A quick search suggests that most "weeded" books are sold on or donated rather than burnt or sent to landfill. Do you have sources that say otherwise?

Exactly right. School teaches you that the point of running an experiment is to try and get the same result as the teacher, while performing a ritual with steps called "hypothesis" and "method".

Hilariously, the wikipedia page suggests that the research looks less like it's "emerging" and more like it's "submerging".
n4r9··on Israel creates fake think tank in likely attempt to dupe AI chatbots
True, but software is very different to general knowledge. For example, it's easier to obtain reference documentation from the person who wrote the language. It's much easier to run tests to validate a given attempt. And the general discourse about how to implement a given solution or architecture is leagues apart from, say, the general discourse around the Israel-Palestine conflict.

My Google wallet replaces not just my debit card but 3-4 supermarket rewards cards, gift cards, gym pass, train & plane tickets, some car parking tickets, and can be used to tap on and off buses and tube trains. It's surprisingly convenient not to have to have my wallet with me whenever I leave the house.

This is supposedly based on Sheldon Axler's earlier and shorter paper "Down With Determinants!" [0]. I lectured mathematics for a while at a "former polytechnic" and used to enjoy leaving print-outs of this sort of paper in the faculty communal areas.

n4r9··on What sort of maths are LLMs good at?
Gowers claims that some methods appear beautiful and natural in hindsight, whilst others do not. That suggests beauty is more than a simple matter of familiarity.
n4r9··on Before Rightmove, there was the Cosmorama
That might help a little, but surely the fundamental problem is RightMove's market consolidation. With competitors like Zoopla and OnTheMarket offering essentially the same product but getting a fraction of the traffic, I suspect RM is engaging in some sort of anti-competitive practise to maintain market dominance. There is a recent lawsuit against them [0], in which the plaintiff pleads that RM employs "exclusionary conduct – behaviour said to weaken rival portals" [1].

Personally, I would hate to go back to the days of trawling individual estate agents and manually comparing prices, floorplans, locations etc... from websites with different formats and UIs. House market aggregators are massively valuable to buyers and sellers, we just need to regulate the industry to be competitive.

n4r9··on What sort of maths are LLMs good at?
Are you claiming that anything you learn and internalise becomes natural? Because there are plenty of proofs (such as the classification of finite simple groups) that remain ugly and unnatural well after they're learnt.

Gowers' claim is that there are particular areas of (or proofs in) mathematics that become especially natural and intuitive after internalising them. This seems uncontroversial to me, and closely linked to ideas of beauty.

n4r9··on Blog about things you don't understand yet
BoJo is a well-established liar, manipulator, and narcissist, so in his case it's natural to suspect duplicity.

His sister wrote an article where she describes reading both columns at the time and recently rereading them both: https://www.newsbreak.com/the-independent-517119/47045597742...

Her take on his motivations are nuanced and compelling imo:

> It was not so much indecision; it was anxiety about being disloyal to his boss. It was also anxiety about advocating a course of action that could hole the good ship Britannia below the waterline unless some rapid free-trade agreements were struck

n4r9··on What sort of maths are LLMs good at?
I'm sure that he has, and I think that his point is solid. Mathematical beauty often has something to do with the transition from "surprising" to "natural".
n4r9··on What sort of maths are LLMs good at?
A thoughtful and measured post, as usual from Gowers. The final note is neat and worth pasting out here in full:

> A good sign that LLMs have reached human level for a much wider class of problems will be if they start proving theorems using methods that, like much of the very best human mathematics, are new and surprising but that with hindsight come to seem beautiful and natural. They should also be methods that are difficult to stumble on by accident. It is hard to say precisely what would count as such a proof, but I think we’ll recognise it when we see it.

n4r9··on Company Offering '100% Human-Written, Never AI' Medical Research Is 100% AI

I'd put it differently. Yes AI is better than it used to be but it's still the lazy choice; human-powered is better but more expensive.

> You can disable the laptop PIN requirement in keepassXC

Thanks for the pointer! I can see an option "Enable database quick unlock (Touch ID / Windows Hello)". It's a bit of a clunky setting though. Ideally I'd like to use quick unlock instead of typing the DB password (e.g. only after session inactivity), but when that setting is checked it also forces you to use it immediately after typing the password.

Oh lord, this is a game-changer.

n4r9··on How to write English prose (2023)
It's less precise than it pretends, in my opinion. At least, it gleefully drops precision in favour of artful insinuation. For example, in reference to Orwell and Strunk & White it uses the word "decrees" to mean "advocates", implying a sort of pompous authority.
n4r9··on Computational chemistry, Locally? My rant on SSH
Recently Claude Code said my authentication credentials had become invalid and I needed to log in again. I recorded the ridiculous number of steps this took:

- Copy-paste link to browser

- Wait several minutes while page load hangs

- Click refresh a couple of times, page finally loads

- Type in work email

- Redirect to work portal, type in work email again

- Asked for work password: open KeepassXC and type in Keepass database password

- KeepassXC additionally demands that I enter my laptop PIN

- Copy work password into work portal

- Asked for Authenticator code: go look for phone

- Find phone, load up authenticator app, type into work portal

- Wait several minutes while page load hangs

- Click refresh a couple of times, eventually get code to paste back into Claude session.

You can buy land in Northern England or Wales at £10k per acre. Even a large bowling centre wouldn't need more than a few acres.

But you're right in general. Looks like this former bowling centre in Inverness is asking for £1.5m: https://uk.businessesforsale.com/uk/for-sale-leisure-develop...

That doesn't address anything unless you stake out and back up your position. Pro-Palestine and pro-Israel advocates both accuse the BBC of bias towards the other side.
n4r9··on British Steel taken into public ownership to protect 'vital' UK supply
For what it's worth, I stopped paying the license fee because of how the BBC sucked up to the Tories in the lead up to the 2019 GE. From Newsnight displaying images of Corbyn that made him look like a Soviet stooge, to Laura Kuenssberg leaking postal vote ballot information, to Alex Forsyth saying that Boris Johnson "deserves" the election.

People say that it's subject to complaints of bias from both sides of the spectrum, but I've yet to see comparable concrete pro-left examples.
