Also Peter Cotton has done some good work comparing these various packages.

He has a wrapper for all of these: https://github.com/microprediction/timemachines

And he compares their performances against each other: https://microprediction.github.io/timeseries-elo-ratings/htm...

Re:Ask HN: Are you still using your Vision Pro? on Wednesday May 15, 2024 @10:54PM (#40374766)
I use it regularly for work and watching sports.

Projecting my laptop screen several feet in front of me reduces eye strain.

Mac Virtual Display would be improved with support for dual screens. I’m also excited for Jump to release a Vision Pro app.

My next MacBook will be a 13" - I just don't need the 16" screen anymore.

Rent control makes renting less attractive and Airbnb more attractive.

Allow higher rents will encourage more building and therefore more supply.

Posted by jpn on Tuesday January 30, 2024 @04:13PM
from the ask-hn dept.

I've found that when explaining complex concepts to colleagues, nothing works quite as well as a good XKCD comic. Randall Munroe has a unique talent for distilling intricate ideas into simple, humorous, and highly relatable panels. It's amazing how often an XKCD comic can illuminate a concept, making it immediately understandable.However, I occasionally find myself searching for a comic on a...

A minimal portion of the net worth of extremely wealthy individuals is spent on luxury items like yachts, bags, and cars. Most of their wealth is typically allocated towards savings or investments, which eventually leads to employment for many of the people in this forum.

> The handicap principle is a hypothesis proposed by the biologist Amotz Zahavi to explain how evolution may lead to "honest" or reliable signalling between animals which have an obvious motivation to bluff or deceive each other. It suggests that costly signals must be reliable signals, costing the signaller something that could not be afforded by an individual with less of a particular trait

Tax fuel instead if we care about the environment. Let the market decide how to prioritize.
