Trying to trim down excessive CPU usage of my web browsers, and lessen the risk of intrusion, I experimented with globally disabling JavaScript and only enabling it on sites where it adds value to me.
That is possible (see below), but immediately showed a big side effect: Bookmarklets will not work on sites that have JavaScript disabled.
Disabling JavaScript globally only allows Bookmarklets on sites where you have enabled JavaScript. Not the situation I hoped for (:
I’ll try it for a while though.

Quite a while ago, Chrome moved from a structure based on “Current Session“, “Current Tabs“, “Last Session” and “Last Tabs” into “Session_#################” and “Tabs_#################” stored in a “Sessions” folder (and similar migrations for other state and configuration files).
The numbers in the “Session_*” and “Tabs_*” files are time stamps of those sessions, for instance one needs to figure out what the “13310808970819630” in “Session_13310808970819630” and “Session_13310808970819630” means.
Lot’s of web-pages with tips and tricks around the old structures are still around, often surfacing high in Google Search results.
I was interested in a particular trick to export Google Chrome browsing history and had a hard time figuring out the easiest solution.

Bookmarklets are basically URLs that execute a JavaScript function.
Sometimes you want to rely on external JavaScript files (for instance jQuery), but Bookmarklets themselves cannot do that.
Bookmarklets can modify the current page though, and use those to load a script, wait until it is loaded, then continue executing.
Often that is OK as you want to operate the Bookmarklet on that page anyway, but be careful though that you do not mess up the page by loading an incompatible script: test, test, test!

Target format:
https://player.fm/importer/feed?url=%s
Where %s is the RSS feed for a podcast as URL encoding.
Example:

Two sites that can help you out getting weather info on the console:
wttr.in
wttr.in is developed by [Wayback/Archive] Igor Chubin (@igor_chubin) / X and looks at the request header to figure out what kind of output it sends.
It supports various output formats, so on my TODO list is to see how they do their mapping: always an opportunity to learn (it’s based on Python and Go so I am curious what libraries they use as well).
From the documentation:
wttr.in currently supports five output formats:
- ANSI for the terminal;
- Plain-text for the terminal and scripts;
- HTML for the browser;
- PNG for the graphical viewers;
- JSON for scripts and APIs;
- Prometheus metrics for scripts and APIs.
The ANSI and HTML formats are selected based on the User-Agent string.
There are more parameters in the documentation on the main page of the repository and through this command:
curl wttr.in/:help
The idea is derived from [Wayback/Archive] GitHub – schachmat/wego: weather app for the terminal.
Oh: Igor has more repositories at [Wayback/Archive] chubin (Igor Chubin) · GitHub (including [Wayback/Archive] GitHub – chubin/cheat.sh: the only cheat sheet you need which is hosted at [Wayback/Archive] cheat.sh; I thought I had blogged about that before, but found it only in a draft note mentioning that I got it via [WaybackSave/Archive] Nicolas Krassas on X: “The only cheat sheet you need cheat.sh“)
7timer
A 7 timer JSON usage example is at [Wayback/Archive] Get Weather from 7Timer! · GitHub
It has documentation at
Output formats can be chosen from HTML, PNG, XML and JSON.

It’s almost
Goal of the current post amend the above posts with information so I can later write a bookmarklet or web-page with JavaScript that – from a x.com or twitter.com – tweet URL can get the JSON, then the images and/or videos in all sizes, then generate a web-page from it for Wayback Machine archival.
