nerdponx commented on I don't think Lindley's paradox supports p-circling   vilgot-huhn.github.io/myw... · Posted by u/speckx

Admittedly not a statistician, but I think the article is missing the point. The reason why people circle the P values is because nobody actually cares about the thing the p-value is measuring. What they actually care about is whether the null hypothesis is true or some other hypothesis is true. You can wave your hands around about how actually when you said it was significant what you were really saying was something technical about a hypothetical world where the null hypothesis is factually true, and so it's unfair to circle your p value because technically your statement about this hypothetical world is still true. This is not a good argument against p value circling, but rather it merely demonstrates that the technical definition of a p value is not relevant to the real world.

The fact remains that for things which are claimed to be true but turn out to not be true later, the p values that were provided in the paper are very often near the significance threshold. Not so much for things which are obviously and strongly true. This is direct evidence of something that we already know, which is thst nobody cares about p values per se, they only use them to communicate information about something being true or false in the real world, and the technical claim of "well maybe x or y is true, but when I said p=0.49 I was only talking about a hypothetical world where x is true, and my statement about that world still holds true" is no solace.

I understood the point of the article to be exploring the extent to which p-values can be interpreted as strength of evidence in favor of the alternative hypothesis. I don't think anyone is spending all this energy on p-values because they think people care about the p-values.

On the contrary, new stuff is cheap and abundant, it’s just optimized for price and quality at the expense of UX. 20 years ago setting up a new TV required plugging in wires and shit. Now it just means installing the walled garden OS, logging in, and handing over your data for collection. Based on the number of people who are OK with this, it’s hard to imagine it changing without people choosing something else.

Different kind of apocalypse

Actually if it was "just" cheap and junky that would probably be fine with a lot of people here. Yes shrinkinflation is a problem but technology doesn't seem to have that problem, prices genuinely do keep coming down. The problem is what companies add on top of the cheap junk in order to obtain an extra revenue stream while also still selling cheap junk. In fact I think I would rather take cheap dumb junk than high-quality but spying on me.

“Not have a TV at all” is a perfectly reasonable choice many people are making now.
nerdponx · a day ago
Sure, that works for TVs. Less so for things like refrigerators and cars. Getting fixated on one particular market obfuscates the big picture.

They don’t care. The customer service era is over.
nerdponx · 2 days ago
It doesn't matter if consumers don't like it if everyone does it. The only choice remaining then is to put up with it or not have a TV at all.

Using an LLM on data does not ingest that data into the training corpus. LLMs don’t “learn” from the information they operate on, contrary to what a lot of people assume.

None of the mainstream paid services ingest operating data into their training sets. You will find a lot of conspiracy theories claiming that companies are saying one thing but secretly stealing your data, of course.

If they weren't, then why would enterprise level subscriptions include specific terms stating that they don't train on user provided data? There's no reason to believe that they don't, and if they don't now then there's no reason to believe that they won't later whenever it suits them.

Not a joke, and a famous piece of J lore!

There have a been at least a couple attempts I've seen posted here of blog posts breaking down the code in a beginner friendly way. One I dug up is: https://blog.wilsonb.com/posts/2025-06-06-readable-code-is-u...

As someone with enough math background to be comfortable with one letter variable lanes and terse notation, this is still needlessly annoying to me because of the removal of almost all non-essential whitespace and grouping related definitions together on the same line instead of putting them on separate lines, and then using blank lines to separate "paragraphs".

I get it and I've heard it before, it's supposed to make it easier to fit more on one screen which is supposed to reduce cognitive burden. You are free to like what you like of course, but it just makes everything look like a jumble.

And even in a math context, I get frustrated if there's no simple glossary or surrounding prose to describe what's going on. Very few people write math this way, as a dense jumble of symbols. Even in the context of written mathematics, this is a very unusual style. I feel like J fans talk about it as if it's a totally normal thing to do if only you knew a little more math.

Perhaps this is a silly question but how do you do functional with no generics? Arent they pretty much required for map/reduce/filter?
nerdponx · 3 days ago
Most Scheme implementations don't have generics, and you have to deal with a different map function for every data structure.

Gauche has a generic sequence interface which is great, and it's one of the reasons as a Python user I like Gauche as my "daily driver" Scheme.

nerdponx commented on Uber is turning data about trips and takeout into insights for marketers   businessinsider.com/uber-... · Posted by u/sethops1

That was my thought too. "Starts"?? I assumed they had been selling aggregated data about user trips the whole time.
nerdponx · 9 days ago
This data is extremely extremely valuable, so my guess is that they were sitting on it until they were sure this was the best business decision. Also they already have their own ads so they have certainly been using this data internally all along.

It sounds like Uber is literally selling data; as opposed to when Facebook is accused of more metaphorically "selling data" (allowing advertisers to target their ads).
nerdponx · 9 days ago
A lot of other companies are in the business of selling data, too. It's not like Uber is uniquely evil for doing this. I'd argue that selling aggregated metrics is comparatively innocuous compared to what Meta does with fingerprinting, shadow profiles, etc. and also compared to what credit card companies, banks, credit rating agencies, ISPs, etc. can do.
