Logit is log odds, not log probability: logit(p) = log(p / 1 - p)

Some decision tree algorithms use it to decide what variable to split on when creating new branches.

Not necessarily. I don't know about other countries, but I remember there being a campaign here in Ireland (with one of the highest rates of cystic fibrosis in the world) to get Or…

Opinion columns are not the same as editorials. But anyway, the Financial Times is well able to publish pieces that say "this currently profitable endeavour will blow up in everyon…

HN is social media.

I can't justify it - it's pure preference and opinion, irrationally held. A big part of it is probably that type of programming I generally need to do is closer to using an overgro…

I also primarily write ML-focused Python. For me, having originally learned R and C at the same time, nothing has ever surpassed RStudio as a dev environment. For the past several …

Bit of a tangent maybe, but according to some expert I heard on the radio this morning, it's a submersible and not a submarine precisely because the vehicle is so totally dependant…

Surely you don't consider your grandparents' childhoods to be "eternity" ago.

It's not just about the USA. Twitter has to follow the law wherever it operates. The way the company went about announcing redundancies in the Dublin office could well fall foul of…

My GP has extra qualifications hanging on the wall for things like minor surgery, ear syringing, that kind of thing. Others near me would mention things like asthma treatment on th…

The EEC became the EU in 1993.

Scientists aren't a monolith though. There few better career boosts than proving everyone else wrong, and the satisfaction of poaching work off a competitor who messed up isn't res…

You can (almost) always buy CDs and rip them. I'd be mildly surprised if an artist was selling music without either a presence on Bandcamp or a store on their own website that you …

With Joyce it also helps if you're familiar with Dublin city accents.

"Price to Entice" is a very real thing where I live. It's basically a way of getting your listing seen by more people, and increasing the chances of a bidding war pushing up the fi…

I think cooking, and food in general, is a great one. There's endless creativity and depth in it. Exploring tastes from a cuisine/culture you're not that familiar with; figuring ou…

Technical analysis (Bollinger bands and the like) would be treated similarly to horoscopes by many people who know how to work a Bloomberg terminal.

Does photojournalism count as art? I'd say it's a relatively safe bet that some photos of the Twin Towers on 9/11 will still be very recognisable in several centuries.

Especially with a young family to raise too. A big polytunnel in the garden might make sense as a time-consuming hobby with practical benefits (though I still think it would be mor…

I'm going to push back very hard on the notion that it's easier to feed your family by picking up farming than by going to the supermarket.

How secure is your job/industry? Not every sector will be hit equally. Now might not be the best time to work in a startup that sells discretionary goods/services. If you've got a …

Would TravelSky step in? To my very limited understanding they have a very similar offering, mostly focused on the Chinese market.

A lot of Russians remember when their country collapsed in front of their eyes. It's probably fair to say that even Putin's harshest critics would be hesitant to go through that tw…

There are a couple of radio shows that cater to my music tastes quite well, I own a lot of albums, and I go to gigs pretty regularly, but I was surprised at how much value I get ou…
