Installation

Install the package globally to make the chrome-devtools command available. You only need to do this the first time you use it.

npm i chrome-devtools-mcp@latest -g

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

Background

This gist includes an enhancement to Debian's snapper package.

The current (as of 2023-07-23) snapper package includes an apt configuration that will automatically take snapper snapshots when you use apt to install/remove/etc. It will add use "apt" as the description of the pre/post snapshot.

With the below changes to the /etc/apt/apt.conf.d/80snapper file and associated dpkg-pre-post-snapper.sh file, snapper will include the full apt command, including the arguments, in the snapshot description.

For example:

$ sudo apt install funky

For a TurrisOS Omnia see WebDAV with Lighttpd on Turris Omnia. Those instructions are slightly different.

Cask-Upgrade

Small utility to help you manage packages installed via Homebrew Cask as it currently can't upgrade installed packages for you or clean up old versions.

The script will ask you if you want to upgrade applications which has newer versions available. Downloads from previous versions of applications will be removed when an application is updated, like what Homebrew has been doing since version 2.0.0. This behaviour can be disabled by setting the environment variable HOMEBREW_NO_INSTALL_CLEANUP.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs
