Anaconda Python needs cleaning every once in a while

Standard

As a user of Anaconda python I have been receiving (Ubuntu) system warnings of low free space in my home directory. Investigating what was causing this I found out that Anaconda python had several versions of each package. The overall size of the pkgs directory was 14+ GB. After cleaning it is about 3GB.

The second largest directory was my mail in Thunderbird.

So it would be wise, especially if you are limited in disk space, to clean Anaconda. The commands I used are as follows:

 
conda clean --all
conda update conda
# just to make sure nothing is broken and
# your environment is updated
source activate <your-environment>
conda update --all
conda clean --all

The Bash Hackers Wiki

This wiki is intended to hold documentation of any kind about GNU Bash. The main motivation was to provide human-readable documentation and information so users aren’t forced to read every bit of the Bash manpage – which can be difficult to understand. However, the docs here are not meant as a newbie tutorial.

Remove Exif data from Images in Linux, How to

Standard

Images usually contain metadata referred to as exif data. Nowadays this includes your camera or phone name and model. Also the location where the image was taken is also included if the GPS is enabled and you did not turn off geo-tagging.

Here’s how such exif data looks like (excluding location which I have disabled):

Facebook Introduces Physical Keys (FIDO U2F) as Security

Standard

Today, January 26, Facebook announced that they have introduced ‘physical keys’ (i.e. usb keys) as an option of the two-factor authentication. Google has already introduced this two years earlier.

A few years ago two-factor authentication was introduced by Google and Facebook among many other companies which allowed the user to set an extra security measure to avoid loosing their account in case their password was stolen. This extra layer required the user, if using a new computer or IP, to enter an authentication code generated (regularly) through an app (e.g. Google’s authenticator for Google accounts).

Check if you’ve had a security breach

Aside

Many of the popular websites and services have been or at some point or will be targetted and exploited. As a result, it is most likely that at least one of your online accounts has been pwned at some point. This doesn’t mean your account has been cracked but it could mean that some of your private information has been leaked (e.g. email, password, personal info like date of birth, etc…). Recently Gmail has been exploited by attachement phishing.

There’s no guaranteed way to check if your account has been hacked but one way is to check if you’ve been pwned. Just enter your username or email to check if you’ve been pwned.
