Modern Device Dimensions for Chrome DevTools

These are modern “Emulated Devices” (a.k.a. responsive dimensions) for Chrome DevTools’ Mobile Device Viewport Mode.

They are specifically Apple devices, subtracting for recent Safari UI (as in window.innerWidth/Height), and cleverly sorted with some dark-arts unicode shenanigans. (This glitchy, unloved portion of the tools sorts lexicographically, because of course it would.) Ergonomics!

Nest Hub Max? Come on. I dropped a bunch of devices that were older and/or close to these dimensions. It obviously doesn’t cover everything (sorry Android/Chrome), but offers a decent spread/increments for common 2023/2024 viewports.

bettercap webui from docker

create volume

docker volume create bettercap

bootstrap/update

Only run caplets.update the first time as every time the entire system caplets folder is replaced with the downloaded contents from github, overwriting your changes, such as the credentials, with default values. You can either backup your changes and restore them later in the system folder, or simply copy the changed caplet files in bettercap’s working directory, in which case they’ll be loaded before the ones installed system wide. https://www.bettercap.org/usage/

Using multiple postgresql version with appropoiate psql and other pg tools version on mac with postgresapp

First make sure no postgres instance is configured to run on startup. And you get nothing when you run this command: which -a psql This is to make sure you don't have anything related to postgres in your PATH, which can conflict. If you do get some hits with above command, you have to manually either remove the installed versions of postgres or just fix PATH and remove ref to that path which has these binaries(psql, pg_dump etc)

For me, i was using brew installed postgres, i had to just comment out a PATH editing line which was inserted by brew in my .bash_profile

Ok, after this we are ready. Now things are simple:

Django Migrations without Downtime
