Setting up additional entropy for your Ubuntu VPS with haveged

June 28, 2020

We've recently ran into an issue with one of our staging servers where a scheduled cron job would occassionally hang for a few minutes before executing.  The issue turned out to be due to a low entopy (i.e. randomness) value in /proc/sys/kernel/random/entropy_avail.

Randomness in Linux is generated from hardware interrupts such as the keyboard, mouse, and disk/network IO.  This goes into a pool which then gets consumed by applications that require randomness for security, such as …

How to connect an Xbox One S controller via Bluetooth in Pop!_OS 18.04 (Ubuntu 18.04)

December 24, 2018

When it comes to screen capture and other media editing tools, Linux really falls behind in terms of good options out there compared to Windows and Mac.

How to resume download over SSH using "rsync"

October 30, 2018

This is one of those "note to self" again.

I needed to download big file (close to 6GB) from a remote server last night but the Internet connection at my AirBnB was a bit spotty and would drop periodically.

Normally, I'd just use scp and even 6GB of data is no big deal on a fast and stable connection. But with a slow or unstable connection, I needed a way to resume the download.

The …
