In WSLv2 there is a way to limit the resources of your linux distro (cpu/memory) to have a better performance on you win10.
To give you an example, this is how it starts on my HP-G5
~$ free -m
total used free shared buffcache available
Mem: 12659 68 12555 0 34 12425
Swap: 4096 0 4096
~$ grep -Ec proc /proc/cpuinfo
8
8 CPU threads, 12G
wslconfig
To define your specs, open cmd and change to your user profile directory
~> cd %UserProfile%
Verify that your WSL distros are stopped:
~> wsl.exe -l -v

GitLab is my favorite online git hosting provider, and I really love the CI feature (that now most of the online project providers are also starting supporting it).
Archlinux uses git and you can find everything here: Arch Linux git repositories
There are almost 2500 packages there! There are 6500 in core/extra/community (primary repos) and almost 55k Packages in AUR, the Archlinux User Repository.
We are going to use git to retrieve our PKGBUILD from aur archlinux as an example.
The same can be done with one of the core packages by using the above git repo.
So here is a very simple .gitlab-ci.yml file that we can use to build an archlinux package in gitlab

This article will show how to install Arch Linux in Windows 10 under Windows Subsystem for Linux.
WSL
Prerequisite is to have enabled WSL on your Win10 and already reboot your machine.
You can enable WSL :
- Windows Settings
- Apps
- Apps & features
- Related settings -> Programs and Features (bottom)
- Turn Windows features on or off (left)
Store
After rebooting your Win10, you can use Microsoft Store to install a Linux distribution like Ubuntu. Archlinux is not an official supported linux distribution thus this guide !
Launcher
The easiest way to install Archlinux (or any Linux distro) is to download the

Security
One of the most common security concerns (especially when traveling) is the attach of unknown USB device on our system.
There are a few ways on how to protect your system.

Cloud Storage
More and more companies are now moving from local storage to cloud storage as a way to reduce the attack surface on systems:

How to install Signal dekstop to archlinux
Download Signal Desktop
eg. latest version v1.0.41
$ curl -s https://updates.signal.org/desktop/apt/pool/main/s/signal-desktop/signal-desktop_1.0.41_amd64.deb \
-o /tmp/signal-desktop_1.0.41_amd64.debVerify Package
There is a way to manually verify the integrity of the package, by checking the hash value of the file against a gpg signed file. To do that we need to add a few extra steps in our procedure.
Download Key from the repository
$ wget -c https://updates.signal.org/desktop/apt/keys.asc

Thank you.Some time ago, I wrote this article: How to create an archlinux docker image from the latest bootstrap but I think the below approach is even better.
Step 0
This step is optional.
If you want to reduce the size of the docker image:
# vi /etc/pacman.conf
and add the below lines:
NoExtract = usr/lib/firmware/*
NoExtract = usr/lib/modules/*
NoExtract = usr/share/locale/*
NoExtract = usr/share/man/*
Step 1
Create the latest archlinux on a temporary directory:
# mkdir -pv /tmp/latestarchlinux/var/lib/pacman
# pacman -Syy -r /tmp/latestarchlinux/
# pacman -S base -r /tmp/latestarchlinux/ --noconfirm
Step 2
dockerized the above directory
# cd /tmp/latestarchlinux/
# tar -c . | docker import - archlinux:latest
99a9d7cd2e357f2463b4bb8f3ad1e8bea4bfc10531dfac1931004405727bf035
Step 3
Actually you ‘ve done !
Just play with it already.
# docker run -t -i --rm archlinux:latest bash
[root@de9b7a1d6058 /]#

Docker is a wonderful application for creating development images quick and not-so-dirty.
I am working -mostly- on archlinux so here are the steps:

Today’s work : A dockerfile to build an archlinux image with sshd
You can find my notes here: Dockerfile notes
I am a very proud member of Athen’s Hackerspace.
I am enjoying the entire 3+ years time (and money) that i’ve spend at this hackerspace. Love it.
Today was a very productive day.
With a good friend of mine, are working to setup an ansible, docker, btrfs workshop !
We want to contribute back to the community and we thought that this is a great opportunity.
We are not guru or anything like that - no, we just want to share the knowledge we are getting by spending time at hackerspace. Nothing more, nothing less. Just share our feedback to all the people that have helped us till now.
So, we are working togeth...
Thank you.
archlinux has chosen to remove TCP wrappers from it’s core packages a couple of years now.
You can read this all about here.
This is how to imitate the tcp wrapper (by the way Wietse Venema rocks! ) functionality with iptables and source range.
iptables -A INPUT -p tcp --dport 22 -m iprange --src-range 158.255.214.14-158.255.214.15 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j DROP
Why i chose archlinux as my primary desktop distro.
a non techinal approach
I am using linux for personal and work related use, from 2002 on a daily bases. I work as a unix system engineer, so i think of my self as an intermetiate user and not a newbie. Not at least on the majority of linux things, cause things are changing too fast and we must adopt to the new world. In this blog post, i will not write down my linux history but i believed that a prolog should be in place, so everybody (me and you) have the same context.
I am using archlinux from May 2009 so its almost four years now. You could say that i got around archlinux as a mistake (i was using ubuntu at that time and a space character after “rm -rf /usr /local/src/something” made me remove my /usr folder) but the test i’ve made (installing archlinux) that evening changed my life.
Why i chose archlinux ?
at that point, I had three options:
a. fedora
b. archlinux
c. freebsb
Thank you.
Reading v13’s blog post about Raspberry Pi under QEMU i was insired to do a similar post for archliux.
This is the easy-way (you can find a lot of copylefts here) !
Step Zero: Downdload the archlinux version of raspberry pi
Go to the archlinux arm site and download the disk image: archlinux-hf-2013-06-06.img
Decompress the image
$ unzip archlinux-hf-2013-06-06.zip
and here you are !

I’ve recently bought a new laptop.
It has a hybrid disk (470G HDD and a 30G SSD).
On the 30G ssd disk i’ve rsynced my archlinux from my previous laptop to the new one.
The boot process takes almost a full two minutes !
I thought i was drafting to the dark side and my sanity wasnt as good as a couple days ago.
After asking to archlinux forum, they suggest to use
# journalctl -b
I have found that there was an entry at /etc/crypttab (that doesnt exist) and the timeout was almost 90 seconds.
Comment that out and then 14sec to login !!!
I was thinking to convert to systemd for quite some time now
So every time someone mentioned something about systemd (on the internet), i was reading his/her story as my life depend on it.
I am using archlinux so when i’ve read Jason’s blog post,
i was very happy. After a few days, Allan post a similar post
and that was the moment i told my self: “It’s time, i can blame Allan for breaking my system”
I run this command
# pacman -S systemd&...Thank you.
