Colony graphs are a simple visualization of computer life forms. A process colony graph, or "ptree graph" for short, shows live processes and their parent and child relationships.

Interesting infographie of great mechanical mechanism

An array of all x86/x86_x64 instruction, very useful

While reading some disassembly, we came across a weird-looking instruction, that was present in most everything we gave objdump.

When starting out as a reverse engineer or malware analyst, it is often tempting to trust your disassembler to correctly resolve the various bytes into code or data. However, to become an expert, it is important to gain as much insight as possible into the Instruction Set Architecture (ISA) of the chip you are working with. This opens many new possibilities: polymorphic code becomes easier to handle, and you become able to use some custom disassembly techniques in your own rootkits or understand these techniques when used by others.

There are a couple groups of settings below. The first couple go in /etc/sysctl.conf or /etc/sysctl.d/filename.conf.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

LambdaPP is a preprocessor for giving you anonymous functions in C.

What is pretty is NetworkManager 0.9.10; it’s like the lightning-quick racing yacht that Larry Ellison doesn’t have and really, really wants, but which somehow also adds a Triple-E-Class-worth of new features just for you.

If you look at /usr/lib/libc.so; the "library" that gets linked when you specify -lc, it is not a library as such, but a link script which specifies the libraries to link, which also includes the dynamic linker itself:

OpenCog is a diverse assemblage of cognitive algorithms, each embodying their own innovations — but what makes the overall architecture powerful is its careful adherence to the principle of cognitive synergy.
