I first heard of Haggus in 2022 when a friend showed them to me and from there I've been hooked on mincecore ever since, specifically the project Haggus. Earlier this year I made it to Obscene Extreme 24, and Haggus played. My favourite album of theirs is Straight From The Slaughterhaus, that's not to say their other material is not good (because it is), I just really like this album.

My background is in penetration testing and system/network administration. About a year ago I decided that penetration testing was not what it once was, and moved into vulnerability research, specifically researching all things Apple. Researching Apple devices I quickly came across the term PAC, and struggled to get my head around it. So because it seems like black magic voodoo I'm going to share and write up some notes on it.

I went to upgrade my home Gitlab server with sudo apt update && sudo apt upgrade -y and was met with the following error. Preparing to unpack .../gitlab-ce_16.6.0-ce.0_armhf.deb ... gitlab preinstall: It seems you are upgrading from 16.2 to 16.6. gitlab preinstall: It is required to upgrade to the latest 16.3.x version first before proceeding. gitlab preinstall: Please follow the upgrade documentation at https://docs.gitlab.com/ee/update/index.html#upgrade-paths dpkg: error processing archive /var/cache/apt/archives/gitlab-ce_16.6.0-ce.0_armhf.deb (--unpack): new gitlab-ce package pre-installation script subprocess returned error exit status 1 Errors were encountered while processing: /var/cache/apt/archives/gitlab-ce_16.

Its been a while since I last posted here, I've like most people been busy with work and life in general, and that's let a few things slide. One of those was my emacs configuration. Being put on bed rest for a few weeks while I recover from an operation, I thought I'd go through my configuration and see if I can tidy it up a bit, and maybe try out a few different packages.

Recently I’ve discovered the wonderful life of code review, and although I tried VS code, it felt clunky, and hard to navigate. Don’t get me wrong VS code has its place, and its a decent editor. But I felt more ate home with emacs. Anyone doing code review will most likely tell you to up your grep game. Or maybe if you spoke to me about code review, I’d tell you that.

Sod it, its my blog, I’ll write about what I want. Its also letting me trial out ox-hugo and spoiler, I love it. But anyway, Rotten Sound… One of my favorite bands of all time, and nearly (by 1 year) as old as me. I got into Rotten Sound when I was 15 with the Cycles album. The cover alone got the young me very intrigued. Still to this day, some 15 years later, this is still very much a goto album of mine.

In January 2021, Qualys released a blog post detailing a terrifying new vulnerability in the Unix sudo program. Specifically, this was a heap buffer overflow allowing any user to escalate privileges to root – no misconfigurations required. This exploit works with the default settings, for any user regardless of sudo permissions, which makes it all the scarier. The vulnerability has been patched, but affects any unpatched version of the sudo program from 1.

I need to get rid of some of these notes I’ve gathered over the years of being a pentester, that although are cool, I never ended up using. So I doubt there will be much in here, I’m not going to explain each one in detail, I just need them gone from my life. Golang HTTP Within golang you can make http(s) requests like so. package main import ( "fmt" "io/ioutil" "net/http" ) func main() { resp, err := http.

Throughout my career I’ve always been the one that knew more that your typical ssh command. Colleges would often ping me if they ever needed to do anything “advanced” with ssh. Recently I found myself in the depths of man ssh and scripting my fair share of ssh shell scripts. So I thought I’d dump some of that knowledge in a post. The Config File If you ever find yourself making an alias like alias foo=ssh you@192.
