Introducing Mempodipper , an exploit for CVE-2012-0056. /proc/ pid /mem is an interface for reading and writing, directly, process memory by seeking around with the same addresses as the process's virtual memory space. In 2.6.39, the protections against unauthorized access to /proc/ pid /mem were deemed sufficient…
Floodgap has had a T1 line since I moved into this house in 2011. I'm one of those weirdos who runs my own hardware and prefers to avoid ...

ramblings by Adam Perry
I wanted to write a post and do a bit of a deepdive into ICMP, ping and traceroute. I’ve found that having a good networking foundation has been a tremendous…
In addition to those on its well-known list of 200+ new features, OS X Mountain Lion also brings along a handful of new UNIX commands and binaries. Most are probably outside the scope of Ask Different (e.g. commands concerning Radius Authentication, Kerberos or Berkeley DB maintainance) but some of them may prove…
"Emails show [Chris Cristie]'s aides did plan bridge gridlock," says Salon . To a transportation engineer, the aides are innocent: bridges can't have gridlock. While we often say "gridlock" to mean "bad traffic," it has a technical meaning.
What is the oldest x86 processor that is still supported by a modern Linux kernel in present time? I asked the above quiz question during the Geekcamp tech conference in Nov 2017 during my emcee role. The theoretical answer as you can glean from the title of this post is the 486 which was first released in 1989. I…
Immutable infrastructure and its tooling has obvious benefits, but the way its current adoption is being done is locking us up in a room whose walls are padded with yaml and we could be losing a lot.

I spent a whole month researching FreeBSD's kernel's virtual memory system to understand why tools like htop, btop and fastfetch report different information about RAM usage. I ended up submitting patches to all of these projects.
Nano How-To explaining how to setup a root file system with only emacs.
When building web services, a common wisdom is to try to reduce the number of HTTP requests to improve performance.
I plan to write a series of articles to discuss some simple but not embarrassingly parallel algorithms. These will have practical usages and would most likely be on many-core CPUs or CUDA GPUs. Today’s is the first one to discuss a parallel algorithm implementation for CSV file parser.
I encountered yet another discussion about OpenBSD PF versus FreeBSD PF . For those who are new to the discussion: OpenBSD developers created PF in 2001, and it rapidly improved to become the most approachable open source packet filter. FreeBSD ported PF over to its kernel in 2004, with occasional updates since. Today…
In this article, you can find how setting the TZ environment variable can prevent thousands of system calls.
VT-x is name of CPU virtualisation technology by Intel. KVM is component of Linux kernel which makes use of VT-x. And QEMU is a user-space application which allows users to create virtual machines.…
Computer code that I’m writing usually doens’t keep me up at night. After all, it’s only bits & bites and if something doesn’t work properly you can always fix it, that’s the beauty of software.
Hello and welcome back to The Cool Blog. I've been meaning to write more but I had these things called finals and then I had to move home for the summer and then I got addicted to Satisfactory again and yeah. Anyway I'm back and time for me to share a project of mine that I've been working on since like March.
