This is why I put the raw url to the script first in my comment. Downloading the script file, doing a chmod +x and then a ./script.sh to execute it is daunting for some.

But I'll add a caveat to my original comment as well.

edit: Looks like I can't edit my original comment anymore.

Here's a one-shot script that does the compare for you, in case it's helpful...

  https://www.sfbaylabs.org/files2/2026-02-11/bad_browser_extension_check_osx.sh

You can run it directly if you cut/paste this in your mac terminal...

  curl -fsSL https://www.sfbaylabs.org/files2/2026-02-11/bad_browser_extension_check_osx.sh | bash

If you're on a mac, you can list all the IDs of your installed browser extensions across all your profiles like this...

  find "$HOME/Library/Application Support/Google/Chrome" \
    -type d -path "*/Extensions/*" -not -path "*/Extensions/*/*" \
    -print 2>/dev/null | sed 's#.*/Extensions/##' | sort -u

Compare to the list of bad extensions. I stuck a stripped down list here...

It seems there are a bots on here commenting and upvoting each other. If HN is susceptible to this, it feels like there's no chance for the rest of the web. Damn.

It is amazing how much they’re gaming the twitter algorithm, everything in my feed is claw/molt/whatever for the last week.

It’s a masterclass in spammy marketing, I wonder if it’s actually converting into actual users.

The statistics on consumers evaluating the purchase of something that is $9.99 vs $10 is well proven.

Switching to round number prices would cost retailers a whole lot more.

There are several US states where, by law, retailers are not allowed to give preferential treatment to credit card paying customers over cash paying ones. Which means, in those states, retailers will be required to always round transactions to the cash paying customer's benefit, where in other states the retailer is allowed to round to the nearest 5 cents. This is going to cost large retailers millions.

Interestingly many of them had already put the work into updating the cash register software to allow for this due to the penny shortages during covid.

I have a bunch of little scripts and aliases I've written over the years, but none are used more than these...

alias ..='cd ..'

alias ...='cd ../..'

alias ....='cd ../../..'

alias .....='cd ../../../..'

alias ......='cd ../../../../..'

alias .......='cd ../../../../../..'
