Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Subtraction Is Functionally Complete
A variation of this has been done using Intel MMU fault handling. Behold: https://github.com/jbangert/trapcc
This is a proof by construction that the Intel MMU's fault handling mechanism is Turing complete. We have constructed an assembler that translates 'Move, Branch if Zero, Decrement' instructions to C source that sets up various processor control tables. After this code has executed, the CPU computes by attempting to fault without ever executing a single instruction. Optionally, the assembler can also generate X86 instructions that will display variables in the VGA frame buffer and will cause control to be transferred between the native (display) instructions and 'weird machine' trap instructions.

Building Processors from the Ground Up
This thread is about hacking something up and not building a product.
For example imagine somebody shares the "one instruction set computer" (https://en.wikipedia.org/wiki/One-instruction_set_computer) project or x86 MMU being turing complete (https://github.com/jbangert/trapcc). Both are clearly just interesting hacks (which may have some interesting implications about security and what does it mean to be "code" etc) and certainly are not intended to be practical products

x86 is Turing-complete with no registers
fwiw, linked to from the article:
> As others have shown, we can compute using alphanumeric machine code[1] or English sentences[2], using only the mov instruction[3], or using the MMU[4] as it handles a never-ending double-fault. Here is my contribution to this genre of Turing tarpit: x86 is Turing-complete with no registers.

Insane x86 Turing Machine that does not run any x86 instructions
I think trapcc is what you're thinking about maybe?

So, what's your favourite programming language?

Hacking from anywhere
1-) Learn Hacking on a debian based distro like Kali Linux - I personally started with tools like nikto, camhacker... and then moved to more complex frameworks like metasploit.

CMV: The Second Amendment "right to bear arms" and the discussions surrounding gun control also apply to hacking tools.
I once had to give a presentation about Metasploit, and whether it was ethically correct for the creator to make it free and open-source, available to everyone. And in researching this I realized that there were a lot of parallels between the arguments for or against hacking tools being readily available and the arguments for or against gun control. I'll just list a few quickly:

Penetration Testing
This phase is where the pen testers practically prove that there exist potential vulnerabilities in the target system. The pen testers do the hacking using an array of technical approaches and social engineering methods to exploit the vulnerabilities. The ethical hackers commonly use Metasploit framework to automatically execute exploitation against the target systems. Moreover, they may install malwares such as rootkit to persistently maintain their foothold and further compromise the target system.
