[Project 2FA-Auth] Generating 2FA codes in your terminal

Hello, guys!

Nowadays, it's normal to find sites and/or services that use "Two-Factor Authenticator (2FA)" to generate 2FA codes and avoid (or make harder) to people steal your account. Thinking about this, I created a BASH noscript that generates a 2FA code in your terminal.

To do this, you need to install GnuPG2 and OATHTOOL in your system and get 2FA-Auth from GitHub.

Check how to install GnuPG2, OATHTOOL and GIT in your GNU/Linux distribution.

Once these programs are installed, type in a terminal:

$ git clone https://github.com/alencc1986/2FA-Auth.git

>OPTIONAL STEP:
>
>Download 2FA-Auth into "/opt" and link the noscript ***2FA-Auth.sh*** into "/usr/bin/", like this:
>
>`sudo ln -sf /opt/2FA-Auth/2fa-auth.sh /usr/bin/2fa-auth.sh`
>
>Or create an alias into your BASHRC `alias 2fa-auth="bash /path/to/2FA-Auth/2fa-auth.sh"` and `source ~/.bashrc`

Read the file README.txt and access the site/service you want to use 2FA, enable this feature and include it into 2FA-Auth.

In theory, any UNIX-like system running BASH and that have GPG and OATHTOOL could run 2FA-Auth. Try it and let me know.

Well... From now on, you don't need to use your cellphone/tablet to generate 2FA codes. Just run 2FA-Auth in your terminal and you're going to have a 2FA code for your services.

​

Have fun!

The biggest events in Linux's history

This list is a summary from [Steven J. Vaughan-Nichols post @ ZDNet](https://www.zdnet.com/pictures/the-biggest-events-in-linuxs-history/)

NB: The website is broken in my linux mozilla browser and in any case a terse linux vi / terminal feel seems more fitting than a bloated javanoscript website :-)

Is it just me or did they make arch harder to install on purpose?

Used to be able to grab the beginners guide and be done in about half hour just basically copying and pasting commands. Now it's all over the place in a so called installation guide. I don't know why they had to go delete the beginners guide with step by step instructions that were so useful. I've been out of the game for awhile now and the task seems super daunting now

You know you are a Linux user when

You see the word “cat” in class and think of “category” instead of the animal as an English teacher.

Restored disk image, recover previous data?

Hello,
I recently restored a disk image on an external SSD. The issue is, I only wanted to restore the image of a single partition, not the entire disk. A careless mistake.
I have a feeling it's possible to recover the lost data, and figured this is the best place to ask for advice.
How, if possible, can I recover the data?
Thanks

imv v4.0 released - a lightweight image viewer for X11 and Wayland

Today marks the v4.0 release of [imv](https://github.com/eXeC64/imv): a
minimalistic image viewer with support for dozens of file formats, including
animated gifs and SVG.

For users of Sway, i3, dwm, or other tiling window managers, imv provides a
lightweight way to view almost any image, with customisable key bindings,
auto-reloading, and the ability to run arbitrary shell commands. imv integrates
natively with both X11 and Wayland, allowing users to run a pure Wayland
desktop environment if preferred. It is also portable, running on Linux, BSDs,
and Hurd.

v4.0 provides much improved support for extending imv's functionality with
shell noscripts. Also added is improved keyboard layout support, hidpi support on
Wayland, native resolution rendering of SVGs at any zoom level, and much more.

I've been working on this release for some time, so I hope you like it. Extensive
refactoring has been undertaken to improve imv in many small ways.

A full list of changes for v4 can be found in the [CHANGELOG](https://github.com/eXeC64/imv/blob/master/CHANGELOG).
