Why everyone should know KPIs

Every Investor has to know KPIs (Key Performance Indicators) to value Investments. But why did I write that everyone should know them in my title? Knowing KPIs helps you even if you don’t invest any of your money. It helps you e.g. decide which job you should take or which customer you should prefer. Deciding between Job Offers - an Example Recently, I decided to start freelancing besides working on my own projects.

How legit is a NewsWatch TV Feature?

Many founders get Emails from NewsWatch TV saying that they will promote your company on an American Television “Morning Show”. I also got a similar Mail for Alphalerts.com and want to explain what you, as a Founder, should think about that. Firstly, if you get such a Mail, it is likely that you promoted your product on ProductHunt lately. NewsWatch seems to scrape the ProductHunt listings and even the founder of ProductHunt wrote a tweet about it:

Drone CI with Podman

I run Drone CI for a longer period now with Docker. Because I decided to switch for multiple reasons from Docker to Podman, this setup had to be changed a bit. In this blog post, I want to cover how to install Podman and how to set up Drone so that it works with Podman. Installing Podman Install the podman and podman-docker packages. E.g. on a Debian based System: apt install podman podman-docker If you currently use docker-compose, then you should also install podman-compose:

Open Source Authentication Solutions

Imagine you run a company and provide multiple web applications for your customers. In the beginning, you probably created a user table and the authentication methods yourself, but from the second application onwards, you will think about using already made open source solutions. That’s the situation I am in right now. I run multiple web applications, which each have their own auth mechanisms and user tables. This means, a user from App1 can’t use App2 unless he creates a new account.

As a Startup founder, marketing is one of the biggest topics you have to take care of. There are tons of marketing automation tools, and most of them aren’t cheap.

Recap: Are Startup Investments profitable?

Since 2017, I invested in multiple Startups via Crowdinvesting platforms. Before that, I only invested in public traded companies.

VR and digital Assistants are the Future

I want to make a prediction. I think in around 10 - 15 years, most of the people in the western World will own or think about owning a Virtual Reality Headset. I also think that digital Assistants like Google Assistant or Alexa will be more important in that context than currently. For context: I own a VR Headset and use digital Assistants since multiple years. I also worked in a team developing a digital Assistant and seeing practical use-cases for AR in the past.

Why Communism doesn’t work

Modern Communists are hard to argue with. Mostly because they say things like “There never was a real communist country”. So it’s hard to take real world examples, because they say countries like the Soviet Union, German Democratic Republic, Cuba or China “never were truly communist”. But I argue there can never be a “truly communist” country. Why? Because it is impossible to create that after my opinion. So if you are open for different opinions, then continue reading.

The Reason why Linux Gaming is so limited

Ever tried Gaming on a Linux system? Even though Linux exists since more than 30 years now, it is still hard to play a Game on it. Most Games don’t even publish a release for Linux. That’s why projects like Wine exist (Wine provides a compatibility layer so that Linux Users can play Windows Games) Why is it like that? For that, we need to understand how a Game works and how a Game Developer thinks.

The Scapegoat called Meta

Many people hate Facebook and Instagram. They say it makes us feel bad, is bad for our health, increases the suicide rate of teens and does many more bad things. But is Meta really all the bad in this world, or is it maybe that Meta just offers a Tool, and it depends how people use it? I want to shine a light on the later part in this article.

Investing in Domains

Since I started creating websites at a young age, I always tried to have good domain names for my projects. I also sold a few - that’s why I want to cover this topic today. A good domain name can be worth quite a bit. Some Domains were sold for multiple millions. But unfortunately, Investing in Domains isn’t quite so easy as you think. I bought at least 45 different domain names and selling them is really hard.

Cost of Political Party Membership in the EU

When I was a kid, I completely ignored politicians and thought they were unnecessary. Now, I understand they are here to represent the people and try to prevent that different groups inside our society kill each other by defining the rules of how our communities work. I am interested to bring my thoughts into this by joining a political party. There are big differences in how much such a membership costs in a country, but even bigger ones when you compare political parties from different countries.

SolarWinds Stock Analysis

When the SolarWinds supply chain attack happened in 2020, I didn’t really get deep into what SolarWinds does because I had to focus on day-to-day business. But now, in 2022, I found out what SolarWinds does because I was searching for monitoring solutions myself. In this article I want to cover the current valuation, a description of what SolarWinds does and my thoughts about the future. Valuation As of March 12, the company trades at 11.

Influence of Sanctions on Economies

The current events in Ukraine led to many economic sanctions against Russia. Despite this war is the result of leaders, not their citizens, the West decided to define many very hard sanctions which resulted into making it impossible to trade with Russian Stocks right now. (After the close of the Moscow Exchange, ADRs listed in the US and GDRs listed on the London Stock Exchange also can’t be bought anymore)

Alternatives to SWIFT

In all the recent news to the War between Russia and Ukraine, I always ask myself about the economic consequences. Recently the EU and US declared a ban of SWIFT currently focused on the state owned banks (which are also the biggest banks in Russia). What’s SWIFT exactly? Before getting into possible alternatives to SWIFT, let’s dive into what the Society for Worldwide Interbank Financial Telecommunication is. It is an Organization with HQ in Belgium which defines Standards and Services for the transaction of financial information.

The Russian-Ukrainian War and the Stock Market

In 2008 Russia fought against Georgia in the Russo-Georgian War. This resulted into a catastrophic situation for the people which live in the areas occupied by Russia. Still today, Russia claims that parts of Georgia are “independent” Countries which do not belong to Georgia. So why do I start with this story? It’s simply because yesterday Putin officially announced to marsh into Ukraine and basically has the same strategy: he says parts of Ukraine are “independent” Countries which need to be free from Ukraine.

The Social Bot Lie

Recently this talk was given on the rC3 2021 Chaos Communication Congress: In summary, Florian Gallwitz explained that there are no “Social Bots” which are often covered in newspapers and magazines. Newspapers and Journalists create stories about AIs which post about political discussions but in reality these “Social Bots” are just accounts from human beings which write a lot of social media posts, classified as bots. The real existing “bots” are dumb systems which e.

Create fast new posts for your Hugo Blog

Static site generators like Hugo, Jekyll or Nuxt are awesome. They provide way faster delivery of your contents to your customers than any PHP solution like WordPress. Unfortunately you have to create the Markdown files for your content yourself, but because every single post has a filename, title, date and often tags as well as a status for draft, I created a simple tool which takes care of doing exactly that.

The Evergrande situation

Over the last days Evergrande China, the 2nd largest property developer in China after revenue, was in all financial news. More than 1.5 million homes are planned by Evergrande and it has $300 billion in liabilities. There are fears that Evergrande China will cause another financial crisis like in 2008, comparable to the Lehman Brothers insolvency. I am watching this very carefully. Most of my personal Assets are stocks and a big decline in the stock market could mean damage comparable of loosing multiple yearly incomes to me.

How I write my Journal

Recently I came across a blog post which described some Tips how to write a Journal on Hacker News. This interested me because I also write a Journal since multiple years (since the 20th March of 2018 to be precise and if we don’t count my Journals I had as a child) and it already helped me in multiple occasions. The author of the article asked himself multiple questions every day and because I think that is too much pressure I want to describe how I do it.

The Difference between Wirecard and Steinhoff

Wirecard and Steinhoff are both companies of German origin which had accounting scandals. In this post I want to describe why these two accounting scandals are completely different and why I choose to take a long position in Steinhoff after the scandal, although I did make a profit with a short position in Wirecard. I am writing this article because I want to describe that shorting a stock with an accounting scandal / fraud isn’t always the best option.

Delete and Resync a Crypto-Wallet on your server

I stake a Cryptocurrency based of Peercoin on a Server since years.

The Problem with Odoo

The history with Odoo started with TinyERP / OpenERP which was a free ERP System. This was a great idea and pioneered the open source ERP environment. But in the last years the name and the vision changed. Now Odoo provides besides the ERP part also a CRM, CMS, Blogs, Forums, E-commerce (Online-Shops), Timesheet, Project Management, Inventory Management, Recruitment, Spreadsheet, Documents, Email Marketing… So in short: Odoo changed from a focus on ERP to an all-in-one solution which seems to cover nearly every application a business needs.

Analyzing the profitability of gTLD registry operators

I am a very big DNS nerd and have always registered new domains for my projects before I even made the concept of my new ideas. We had tests about the Domain Name System at my professional school and I can’t remember I ever not scored the highest… So as someone who currently pays for 33 domains a year of which all are for private projects and none generates money I had an idea for a new gTLD which I wanted to operate.

The Workhorse Group Story

The Workhorse Group Incorporated is a EV company which primarily produces delivery vans and got lately popular with a rising share price because it was viewed as one of the possible winners of an 8 billion USPS contract to replace old delivery vans. This contract busted, however I started writing this article before the deal busted - so don’t be surprised by the high numbers. I owned this stock for several years and wanna display my view of the company in this blog post.

Why Bumble is overvalued

Yesterday Bumble had it’s initial public offering (IPO). The starting price was 43 USD, a valuation of more than 8 billion and it shot up to 76 USD, a valuation of over 13 billion.

On the 23andMe and VGAC Merger

On the 4th February 2021 23andMe and VG Acquisition Corp announced that they will merge, bringing 23andMe into the public. As VGAC is already tradable in the public market, the shares have skyrocketed to 19 USD. But this is crazy… Why this is crazy? First you should know that the initiators of a SPAC commonly have additional rights to e.g. buy additional shares. They also mostly pay 10 USD per share.

Apple environmental friendly?

Why Apple Products aren’t as environmentally problematic as many believe. Apple bashing is popular these days. Louis Rossmann, Hugh Jeffreys and others are talking about repair issues on YouTube, Mark Zuckerberg sees Apple as an unfair competitor and Xiaomi mocks Apple for Not Including Charger and then does the same. So in this world where Apple bashing is popular I wanna tell you my opinion. I bought my first new Apple Products this year (primarily caused by the impressive performance of the M1), but I already have used used Apple Devices for a longer period.

Comparison of Email Hosting Possibilities

I’ve hosted my own Mailserver in various configurations since more than 6 years now. Since then I’ve taken multiple breaks from hosting it myself and explored other solutions for hosting emails with your own domain names. Because my own Mailserver has lately problems (downtimes) I wanna explore other possibilities of hosting my email addresses. So let’s take a look… Self-hosting (VPS, Tools like Mailcow, Mailu, etc) You simply setup a Mailserver with software like Mailcow, Mailu or Mail-in-a-Box on a virtual Server and manage it yourself.

Fighting the Tinder++ Malware

People who search for love are more vulnerable than happy couples. Especially people who lost their Tinder Account because Tinder has banned them. There is a malware out there which targets exactly this kind of people. If you search for “unban tinder” on Google and or YouTube you find many videos and sites which recommend the “Tinder++” App. Tinder++ aims to bring you free Tinder Gold and unban your Account.

Switching to Hugo

Moving to Hugo I started this blog as my first blog using a static website generator. Back then I used what everyone else was using: Jekyll. But Jekyll has it problems. I don’t use Ruby for anything else and the management of the dependencies / ruby versions / etc of my static blog was too much for me. I blog way more often in german on my other WordPress sites and one of the main reasons is that it is easier and Jekyll wasn’t as easy as I expected.

Forget Bash, take Python!

I wrote bash scripts for several years now. You can find old bash scripts of mine on GitHub but most of them aren’t maintained anymore - and I have a reason for that. But before I give you my reasons for not using many bash scripts anymore, lets look at the benefits of bash: It super easy and you basically already can it if you write Linux / BSD commands There are frameworks out now which give you advanced features like testing It works out of the box on nearly every Linux / BSD system Okay - sounds good - so what’s my problem?

Gitea Auto Update Script

I’m a Gitea user for a long time now. Gitea is a nice application to build your own light and fast version of git hosting services like GitHub or GitLab. Gitea has one problem thought. It doesn’t update automatically. A issue for that is open nearly 2 years: https://github.com/go-gitea/gitea/issues/518#issuecomment-441742904 If there is one thing that I really hate, it is that a security sensible web application doesn’t update automatically. Because of that I have begun to write a update script for Gitea before 4 months.

FreeBSD: nvidia-driver installation

After installing FreeBSD to my workstation, I wanted a desktop environment. I’ve installed gnome3 after reading the official documentation https://www.freebsd.org/doc/handbook/x11-wm.html. But nothing has worked. So, I installed the nvidia-driver for my two GPUs. The first documentation I’ve found is from “7.3-RELEASE”: https://docs.freebsd.org/doc/7.3-RELEASE/usr/share/doc/en/articles/compiz-fusion/nvidia-setup.html. (I use 11.1-RELEASE) Don’t use that documentation to make your settings in /boot/loader.conf! There stands: nvidia_load="YES" And that’s simply not right for the newest driver! You should enter the following line:

APU2C4 - LED blinks 5 times …

I bought a APU2C4 Board (from the swiss company “PC Engines GmbH”) and multiple components because I want to build a custom pfSense router. I’ve ordered the device several weeks ago and haven’t used it until now. That’s because I made a few mistakes (which I want to write now): First Mistake: I used a power supply with 12V and 2A from china. Visible by: The LED on the back of the device blinks 5 times - then no more again.

First try of Jekyll

I’ve already using different blog systems like WordPress and Ghost, but this is my try to start a blog in english about personal and development topics with Jekyll. Maybe is the domain not my best choice (.de is the domain for germany), but as I haven’t any project on it, I will use it. I will be using GitHub as hosting service. That will have a few great side effects: you can download my whole blog via git clone, in the same way you could mirror my blog and if you want to notified when a new change happens, you could subscribe my Blog via the “Watch” Function of GitHub.
