Using FlameGraph for displaying disk usage.

I was looking for a LLMNR commandline lookup utility. Actually, dig can do the job quite fine.

I thought I was understanding pretty well how bash argument processing and various expansions is supposed to behave. Apparently, there are still subtleties which tricks me, sometimes.

How I found remote code execution vulnerabilities via CSRF on the administration interfaces of InternetCube applications and of the YunoHost administration interface which would have been used to execute arbitrary code as root. These vulnerabilities were fixed in YunoHost 3.3, OpenVPN Client app 1.3.0. and YunoHost 3.4.

I'm not a super fan a WISWYG text editors. They never really do what I want them to and often often do what I don't whan them to. Here's the workflow I'm using to generate simple text documents (resume, cover letters, etc.) from Markdown, YAML and Jinja2 templates.

Trying to bring back some old IP spoofing Firefox extension for watching South Park episodes.

In the previous episode, I talked about some argument and shell command injections vulnerabilities through URIs passed to browsers. Here I'm checkig some other CVEs which were registered at the same time.

While reading the source of sensible-browser in order to understand how it was choosing which browser to call (and how I could tweak this choice), I found an argument injection vulnerability when handling the BROWSER environment variable. This lead me (and others) to a a few other argument and shell command injection vulnerabilities in BROWSER processing and browser invocation in general.

In Tail Recursion In Python, Chris Penner implements (self) tail-call optimization (TCO) in Python using a function decorator. Here I'm extending the approach for sibling calls.
