Print to Brother PTP300BT from a computer

Printing to a Brother P-Touch Cube PT-P300BT label printer from a computer


The Brother P-touch Cube PT-P300BT labelling machine is intended to be controlled from the official Brother P-touch Design&Print 2 app for Android and iOS devices, instead of from a computer.

This Gist provides small code revision and some additional scripts to the dogtopus/Pipfile one, which in turn is forked from the excellent stecman one, in order to print text labels via scripts on computers with different O.S. or subsystems.

The scripts are used to convert text labels to appropriate images compatible with 12mm width craft tapes like [TZe-131

View Software RAID 1 setup on Ubuntu Server

Looking to create a Software RAID 1 setup for your 2-disk server on Ubuntu Server 20.04?

Screen Shot 2020-06-05 at 20 55 31

Let's start with the basics: the official guide by Ubuntu ( is outdated/wrong. And as of March 2021 it's possible that there's a bug as well with how the bios_grub partitions are created when using multiple disks.

Now on to the solution:

  • Select "Custom storage layout" when you reach the storage configuration step of the installer.
  • If the disks have existing partitions, click on each disk under AVAILABLE DEVICES and then select REFORMAT. This will (temporarily) wipe out the partitions.

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](

Generating Authy passwords on other authenticators

There is an increasing count of applications which use Authy for two-factor authentication. However many users who aren't using Authy, have their own authenticator setup up already and do not wish to use two applications for generating passwords.

Since I use 1Password for all of my password storing/generating needs, I was looking for a solution to use Authy passwords on that. I couldn't find any completely working solutions, however I stumbled upon a gist by Brian Hartvigsen. His post had a neat code with it to generate QR codes for you to use on your favorite authenticator.

His method is to extract the secret keys using Authy's Google Chrome app via Developer Tools. If this was not possible, I guess people would be reverse engineering the Android app or something like that. But when I tried that code, nothing appeared on the screen. My guess is that Brian used the
