  • Suppose the average person p0 has n acquaintances. Then a naive approach would say that each of p0’s acquaintances (call one of them p1) also has n acquaintances, leading p0 with n2 acquaintances of the second degree.

    However, in a social network, many of p1’s acquaintances are shared between p0 and p1. Let’s say that rn (1/nr≤1) of p1’s acquaintances are actually first-order acquaintances of p0. The lower limit for r is 1/n because naturally one of p1’s acquaintances is p0 themselves.

    This gives us n⋅(1−p)⋅n = n2⋅(1−p) as the number of second-degree acquaintances, if my math is mathing. Increase n for more extraverted people in the network, and increase p for more closely-knit networks.

    To model the headline X % know someone who knows, we solve 1 / [n2⋅(1−p)] ≥ x where x is X% expressed as a fraction. Plugging in n=100 and p = 1/10 (I pulled these numbers out of my ass) and X=20% we get 1 / [1002 ⋅ (1−.1))] = 1 / [ 10^4 ⋅ 0.9 ] = 1 / 900; again, if my math is mathing.

    So this headline is true if about 1 in 900 people are in a relationship with AI.



  • The browser can never know what information is needed for a certain use case. So it needs to be permissive in order to not break valid uses.

    For instance, your list does not include the things a user clicks on the website. But that’s exactly the info I needed to log recently. A user was complaining that dropdowns would close automatically. We quickly reached the assumption that something was sending two click events. In order to prove that, I started logging the users’ clicks. If there were two in the same millisecond, then it’s definitely not a bug but a hardware (or driver or OS or whatever) issue.



  • First comment from the link:

    Every time you open LinkedIn in a Chrome-based browser, LinkedIn’s JavaScript executes a silent scan of your installed browser extensions. The scan probes for thousands of specific extensions by ID, collects the results, encrypts them, and transmits them to LinkedIn’s servers.

    That is very different from “searches their computer for installed software”

    Can you tell me how any user ever finds out that you need to double click an icon on their desktop?

    I completely agree with you on this. I hate that Windows doesn’t disclose what areas can be clicked anymore. It used to, back when computers where new. Nowadays if you wanted to show a new person how to use a computer, you’d have to very explicitly explain things that would’ve been obvious from the looks just 10 years ago. (Ok, maybe 15.)

    What is a new Apple user supposed to do? Try all of the 30-ish gestures one can make on every side and every corner of every app? That’s just stupid.

    Unless the user is actively navigating, the header is dead weight. The header should hide on scrollDown and reveal on scrollUp. Let the content breathe.

    This one I actually hate. Often I just want to scroll up a few pixels, either to satisfy a mild compulsion or to align the content so I can see most of it. This is completely ruined if the navbar pops back in. Leave it at the top of the page, where it belongs, not at the top of the viewport!
