inherit environment variables from PID 1

You can inherit the environment variables from PID 1 by iterating over the list of null-terminated strings in /proc/1/environ, parsing the first characters up to the first = as the variable name, setting the remaining value as that variable, and exporting it.

The Code Snippet

This works with multiline environment variables, and environment variables with arbitrary values, like strings, including = or JSON blobs.

Paste this in your current terminal session to inherit the environment variables from PID 1:

MD5 Collision with CRC32 Preimage

Here's the scenario: We want to craft two different messages with the same MD5 hash, and a specific CRC32 checksum, simultaneously.

In other words, we want an MD5 collision attack and a CRC32 preimage attack.

This might seem like a contrived scenario, but it's exactly the one I faced while producing my PNG hashquine (Yes OK maybe that's also a contrived scenario, cut me some slack).

On its own, a CRC32 preimage attack is trivial. You can craft a 4-byte suffix that gives any message a specific checksum, calculated using a closed-form expression (which I am too lazy to derive, not even with assistance from Z3). It's not an attack per-se, since CRC32 was never meant to be cryptograpically secure in the first place.

Jailbreak Firefox!

Jailbreak-Firefox

This script allows you to install unsigned extensions (ones that aren't approved by Mozilla) on normal Firefox builds and the official Snap! That's right, no "Firefox Developer Edition" nonsense required!

⚠️ Disclaimer ⚠️

This script is not well tested, like at all. This script might break things, possibly important things. You should probably take a backup of your Firefox profile before using it. You have been warned.

Dependencies

sudo apt install -y curl unzip zip
# Only needed when jailbreaking the Snap

Because cross-compiling binaries for Windows is easier than building natively

Because cross-compiling binaries for Windows is easier than building natively

I want Microsoft to do better, want Windows to be a decent development platform-and yet, I constantly see Microsoft playing the open source game: advertising how open-source and developer friendly they are - only to crush developers under the heel of the corporate behemoth's boot.

The people who work at Microsoft are amazing, kind, talented individuals. This is aimed at the company's leadership, who I feel has on many occassions crushed myself and other developers under. It's a plea for help.

The source of truth for the 'open source' C#, C++, Rust, and other Windows SDKs is proprietary

You probably haven't heard of it before, but if you've ever used win32 API bindings in C#, C++, Rust, or other languages, odds are they were generated from a repository called microsoft/win32metadata.
