## Overview of hacker-friendly single board computers

The linux gizmos mag has a nice and helpful review/compilation of all kind of single board computers created in Jan 2017.

Brief reviews on the site look like this:

They also have a spreadsheet online to get the full overview.

Why do I blog this? I always wanted to play around with one of these. I did a bit playing around with Arduino but never went for something more than a 20-40 lines of code. Maybe this helps to get me into a deeper sphere of playing around with these quite powerful things.

I found a rather quick way to get emoji in my document. But this is the brute force quick way. The russian way. It always works but is not that elegant. PDF-images.

## How to

1. Read this blog post „Emoji in LaTeX documents“
3. Search the emoji-PDF files you need for your document
4. Copy them to the folder where your .tex-document resides
5. Define a shortcut/macro to include those emoji-PDF files you need
6. Include the following code in your .tex-document
\usepackage{scalerel} % needed package to scale the pdf-images perfectly
\def\emojithumbup{\scalerel*{\includegraphics{emoji_thumbup_1F44D.pdf}}{O}}
\def\emojistar{\scalerel*{\includegraphics{emoji_star_2B50.pdf}}{0}}


This my five star rating
\emojistar\emojistar\emojistar\emojistar\emojistar
I would say \emojithumbup for this easy integration.


Why do I blog this? Because when I tried to integrate the coloremoji.sty class in my LaTeX document, I got a series of issues with conflicting textinput encodings not matching the one the coloremoji expects. This way your avoid any new encoding issues by directly integrating PDF-images which is what will happen anyway with that class. maybe you need to include \usepackage[pdftex]{graphicx} too.

## Why I do not like group chat that much…

…someone – actually Jason Fried – wrote that down so I do not have to do this.

In his posting „Is group chat making you sweat? — Group chat is like being in an all-day meeting with random participants and no agenda.“ he points out the things that matter most. (PDF as depublication protection)

I will cite only a small part of it here:

[…] You must really have something against persistent group chat as a primary method of communication? Yes, in most cases I do. And it’s only because we’ve been using it at 37signals/Basecamp for 10 years. I’ve seen the distraction, anxiety, stress, and misunderstanding it can cause, and those are things that can really damage people and an organization. […]

Why do I blog this? I have really tried to use things like e.g. Slack or Threema Groupchats. But it always ended with me abandoning the software completely or shutting down all notifications and only opening the applications occasionally. They are too much a distraction to me.
