Historically, all memory on x86 architectures were equally accessibly by all CPUs on the system. This is an effective implementation, but there's increased bandwidth on the bus, and the more CPUs you have, the further away from the memory it is. This layout is called Uniform Memory Access.

Modern x86 architectures introuduce the concept of memory nodes (also referred to elsewhere as zones or cells), where new writes are associated with a CPU's memory node. The nodes are connected by a bus, so all the memory is still accessible via any CPU, but of course, we have faster memory access time for CPUs accessing local nodes.

When you have a virtualization layer on top, and you are scheduling workloads, you can take advantage of this by pinning processes to specific CPUs.

Technologies to learn to become a Back End Developer (Python/Django)

Linux - be proficient using Ubuntu for example and the CLI and understand how the shell works, what are environment variables, subshells, processes/tasks, etc...
Docker (and docker-compose) - what are containers and how they work (conceptually) and how to create and run ones
Git - what does version control system mean and how to use Git
RDB (relational databases) - what are relational databases, and understand tables, how to create them and make relations between them as needed... also understand that through SQLite and PostgreSQL (preferred) or MySQL
Python - how to write Python very well and understand its [OOP] implementation...
Virtualenv - And how to create virtual environments for python to isolate it from the system's installed version...
Virtualenvwrapper to manage virtual environments easily

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

Port forward over wireguard to VPS with static IP

This is write up is on how to port forward over wireguard. I am going to be port forwarding a mail server running MailCow on my local server, but really any service can be port forwared with some modifications to the IPTables commands in the wireguard file.

I am using a cheap Vultr VPS as my proxy server, if your intrested heres a referral link https://www.vultr.com/?ref=9019507 where I get $10 or if you plan to spend more then $35 on your account you will get $100 and I will get $35 https://www.vultr.com/?ref=9019508-8H

My Setup

Debain 10 Buster
Tunnel subnet: 10.1.1.0
Proxy-VPS Tunnel IP: 10.1.1.1

Generating Authy passwords on other authenticators

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.
