owenjonesuk··on Getting specific about generics
I think the author is a woman, from the name Emily.
owenjonesuk··on It is as if you were doing work
Firefox implemented something a few years ago where buttons on pop-ups were greyed out for a few seconds, to avoid this. I believe it was a security concern that an online game could get you to click in a certain place at a certain time, and make a pop-up just before it asking for permission to do something, so you clicked Accept without meaning to.
owenjonesuk··on Ask HN: What're the best-designed things you've ever used?
In-ear headphones always fall out of my left ear. At first I thought it was something to do with the ridges in my ear, because they're quite different between my left and my right ear. Then last year I had an ear infection and the doctor told me that I have a narrow ear canal in my left ear, so I'm guessing that's the reason. Apparently it also means I'm more prone to getting ear infections.

Bose have something for in-ear headphones called StayHear tips. They work really well for me. They look exactly like Earhoox, so maybe if I'd found Earhoox first I could have just used them.

owenjonesuk··on The super-recognisers of Scotland Yard
Thanks for introducing me to aphantasia, which I hadn't heard of. For others that haven't, it means not being able to imagine images or sounds in your mind. It was only discovered recently, and I think it was popularised by this blog post by Blake Ross, which is well worth a read.

owenjonesuk··on Why isn’t the fundamental theorem of arithmetic obvious? (2011)
Actually, you're pretty much spot on. The word you want is "irreducible", rather than "indivisible". In general rings there are irreducible elements and prime elements, and they have different definitions. You're looking for a unique factorisation into irreducibles.

owenjonesuk··on The Diceware Passphrase Home Page
I discovered Diceware a few months ago when looking for a password generation scheme for my company. We were just letting people choose their own passwords before, which I don't think is a good idea. I really like it. My only annoyance, which isn't really the fault of Diceware, is that for lots of passwords I am required to have a capital letter, a digit and/or a special character. Obviously this is to try and increase the entropy in the password, but I know that I have enough entropy in my diceware password and I just want something easy to type.

I also discovered the password strength estimator zxcvbn at about the same time. It's pretty clever. It works out which password generation schemes could be used to generate your password and then uses that information to calculate the entropy correctly (assuming the attacker would know what scheme you used).

owenjonesuk··on Why Chinese Is So Damn Hard (1992)
Different dialects of Chinese use the same characters. Cantonese, for example. Switching to pin yin would only work for mandarin.
owenjonesuk··on The Same-Day War: Amazon, Google And Walmart Race To Bring Your Groceries
I'm from the UK. My colleagues with kids all do their grocery shopping online. They love not having to find time to go to the supermarket, and not having to entertain their kids while they're going round.

From my own experience, it's annoying the first few times you do it but after a while it gets easier. One cool thing is you can have a list of things you regularly buy and easily add them all to your basket. And they know it's harder to get inspiration online so they try very hard to suggest new things to stop you from getting bored.
