If I propose odds based on survival tables for other companies of that age (I think for six years, the annual risk is 9 %), which side of the bet would you like to take?

Many of the comments in this discussion remind me of that Rothchild analysis in the second half of the 1800s when France had problems with a revolution. > A friend asked Baron Rothschild what he was doing in response to Paris Commune: &g

It literally has to be compromised to work. If the roulette machinery was perfect, you would be able to predict the outcome with Newtonian physics at the start of the spin. It has to have irregularities and asymmetries to trigger chaotic be

This used to be one of my recurring nightmares when I was a child. The three I remember were (1) clocks suddenly starting to go backwards, either partially or completely; (2) radio turning on without being able to turn it off, and (3) house

I think it mattered a lot more a few years ago, when the user's prompts were almost all context the LLM had to go by. A prompt written in a sloppy style would cause the LLM to respond in a sloppy style (since it's a snazzy autocom

Cross-validation. The slope overfits when the test set is included from the data the model is fitted on.

Because it's a direct way to measure predictive power, and it says so: "We’ll use leave-one-out cross-validation"

I imagine some systems may start out by tinkering with definitions in the REPL in the live system, and then as it grows, the best definition of the system is found in the current state of the REPL, rather than any more formal specification

No, the post is doing cross-validation to test predictive power directly. The error will not decompose as neatly then.

With one term it gets more robust in the face of excluding endpoints when constructing the jackknife train/test split, I think. But you're right, it does sound fishy.

Although you are technically correct, if you look at the data you'll recognise that for this narrow span of values, the logistic fit will be practically equivalent to the linear. Indeed, they perform the same in cross-validation. Here&

When I benchmark LLMs on text adventures, they reason like four-year olds but have the worlds largest vocabulary and infinite patience. I'm not surprised this is how they approach programming too.

Code review is great for spreading context, but they also are very good at finding bugs. If you want to find bugs, review is one of the best ways to do it. https://entropicthoughts.com/code-reviews-do-find-bugs

> If you're not using Emacs, it would be crazy to fire up Magit just to do a git commit or rebase. What makes you say that? > what do you mean "save is C-x C-s?" what does that even mean? Magit never asks you to C-x C-s

Surely the mistake here is conflating "learning Magit" with "learning Emacs"? I can run Java applications while knowing nearly nothing about the JVM. The same is true for applications based on Emacs.

by kqr 8mo ago
You can use Magit even if you're a Vim user. You don't have to buy into the whole Emacs system – you can treat Emacs as the virtual machine that runs Magit.

Huh, it has to be Google, specifically, too! There used to be a shortcut for this action on HN (a link under the submission saying "web" or something?), but it seems that has been removed.

I have an HP 12c, so doing compounding maths is about the same level of chill as not doing it.

The measurements should take that into account, yes. (There are ways to estimate this.)

A lot of people in this discussion seem to compare the price of single-use nappies to that of buying new cloth nappies and then giving them to the landfill once done with one child. I can strongly recommend buying them second hand and then

Did you calculate based on buying cloth nappies second hand and then reselling them? That was a great alternative for my family. Worked out to something like $100 in total nappy costs for one child, including the opportunity cost of tying u
