Some testla.com artifacts indicate it runs on PHP being deployed from a git repository

Posted by jpluimers on 2025/06/24

A few years back, a few interesting files turned up that are directly served from the testla.com web-site right in the middle when Musk used their software engineers to asses twitter.com code quality:

Some do not exist (of which some any more):

zxcvbn: Low-Budget Password Strength Estimation | USENIX

Posted by jpluimers on 2025/06/19

Many web-sites and password managers have a strength indicator built-in.

This is a really good example (with open source JavaScript code!) of one: [Wayback/Archive] zxcvbn: Low-Budget Password Strength Estimation | USENIX

Be aware though that it stores a plain text file named passwords.txt on your system (this seems to confuse some users, especially when their password is in it).

Homans password behaviour does not change much over time, so this half hour 2016 presentation on it is still current: [Wayback/Archive] USENIX Security ’16 – zxcvbn: Low-Budget Password Strength Estimation – YouTube for which you can download:

A PDF can run JavaScript, which means it can hosts a VM for Linux or Doom

Posted by jpluimers on 2025/06/12

A few years back, this question popped up: [Wayback/Archive] Embedding JS into PDF : cybersecurity

The answer is yes, and you can take this far. Virtualisation far. Which is what these repositories – both by [Wayback/Archive] ading2210 · GitHub – did:

Via [Wayback/Archive] Angry Nerds Podcast – YouTube -> [Wayback/Archive] Angrynerds 235 – Automasturbator – YouTube -> 1540 seconds at [Wayback/Archive] Angrynerds 235 – Automasturbator – YouTube – t=5040s

1:24:00 Hadden we Doom in PDF-vorm al eens genoemd? https://github.com/ading2210/doompdf Er is een vervolg, nu gewoon linux draaien in een PDF https://github.com/ading2210/linuxpdf Dus in feite gewoon een PDF-VMetje

unix – How come is this command returning “GET A LIFE!”? – Stack Overflow

Posted by jpluimers on 2025/06/11

Didn’t know nx had a scriptable RPN command-line calculator dc (for Desk Calculator) which does not seem to need white space characters in the input stream or input file.

It likely is a source for command-injection attacks given the question [Wayback/Archive] unix – How come is this command returning “GET A LIFE!”? – Stack Overflow, so I did a bit of digging and found this great platform:

What is the Python 3 equivalent of “python -m SimpleHTTPServer” – Stack Overflow

Posted by jpluimers on 2025/05/29

Now that Python 2 has been dead for long enough (has it been unsupported for 5 years? yes it has: [Wayback/Archive] Status of Python Versions), it was finally time to change my alias for running a local web-server to serve files from a directory (:

So, from [Wayback/Archive] What is the Python 3 equivalent of “python -m SimpleHTTPServer” – Stack Overflow (thanks [Wayback/Archive] ryanbraganza, [Wayback/Archive] k.avinash and [Wayback/Archive] Petr Viktorin):

python -m http.server 8000, it will start the server on port 8000

Docs with the migration hints: [Wayback/Archive] 20.19. SimpleHTTPServer — Simple HTTP request handler — Python 2.7.18 documentation

Yes, you can globally block JavaScript and enablpe per-site, but you block Bookmarklets too

Posted by jpluimers on 2025/05/16

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.

Coo responses to b0rk no Twitter: “is there an easy way (in the browser, at runtime) to generate a call graph of which functions called which other functions in a javascript program?”

Exporting Chrome History (with the “new” configuration and state file structure), and Epoch dates on various systems

Posted by jpluimers on 2025/05/02

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.

GitHub – randomaccess3/googleURLParser: parser for Google search strings

Posted by jpluimers on 2025/05/01

Back when I observed the Google Search sei parameter which I hadn’t seen before yet, I bumped into [Wayback/Archive] GitHub – randomaccess3/googleURLParser: parser for Google search strings

It covers a truckload of parameters, including the sei one, which isn’t as new as I thought, as it was at least 2017 old: [Wayback/Archive] [Neat URL] Yet another Google parameter… · Issue #25 · Smile4ever/firefoxaddons · GitHub

Some SQLite things I recently learned a while ago

Posted by jpluimers on 2025/04/30

More on the reason why I learned a few SQLite things soon, but for my link and documentation archive, below is what I learned.

Most commands use the database file C:\temp\History which has no extension as that is how I got the file in the first place (spoiler: it’s a Chrome browser History from one of my user profiles).

Let’s get started:
