TTT 32.1: OpenSSL Vulnerabilities Patched
The newest version of OpenSSL is out, and they patched some doozies. A researcher found one vulnerability which led to one of the maintainers finding a similar bug, which together, could trigger a buffer overrun in the x.509 certificate verification system, triggering a denial of service for that server. Good news is that these vulnerabilities were repaired.

#gratitude As we turn to the thanksgiving season, here in North America, let us begin to count our blessings. I know this year has been hard, brutal, for most of us, but we are still here. Many of us still have our families and friends around us, and we don’t have to contend with Fraudci’s nonsense. Find things to be grateful for, today, focus on those things rather than on the things that are far less than ideal.

TTT 32.3: Using yay to Work With the AUR
Many of you who have been around for a while are familiar with this, but I thought I’d toss this in this week for the sake of new users, or Manjaro users who may not use the terminal much, if at all. First things first, Arch already has about as many native packages as Debian or Fedora in its primary repositories, or repos, but what they don’t have, which is still quite a good number of things, can likely be found in the AUR, which is the Arch User Repository. The difference between the AUR and the main repos is that the main repos are maintained and supported by the team that develops Arch, where the AUR is maintained (sometimes) by users, and things aren’t necessarily supported well there. In my experience, they may not even always work. Here is what the AUR is is a repo where the source binaries are stored for a vast number of projects and programs are kept to be built into native packages through tools like yay. Yay is one of the most popular AUR helpers. Think of AUR helpers as pacman for the AUR. They will help you to work with AUR packages, from selection, to building, to installing, then updating, and finally uninstalling, as needed. Yay has some competition in pikaur, paru, and pacaur, among others.
First, we have to install some dependencies for it through pacman
Sudo pacman –Sy git base-devel
Then type the following in this order:
git clone https://aur.archlinux.org/yay-bin.git
cd yay-bin
makepkg -si
This will install the Yay AUR helper.
Now to use it:
First, we have to know the precise name of the package in the AUR, so Yay has its own search function:
Yay –Ss package-name-here will search for it in both the AUR and in main repos
Updating AUR packages using yay
Yay –Sua
Remove unnecessary dependencies
yay -Sc
Remove unnecessary dependencies and cached packages (say you are wanting to free up a good deal of storage space)
yay -Scc
