The RasPi | A quick introduction


Apache Setup Raspberry pi mini computer to dedicated web game server. LAMP. Apache Raspberry pi mini computer. Dedicated game server.

That is simply just another http web server powered by Apache Software

and the Raspberry pi Foundation with Raspbian Debian OS Stretch Lite on it.


The small computer is in great demand for many. You get the Raspberry pi (abbr. RasPi, RPi) for about 40€, a full-sized computer with the size of a credit card. Especially for people who want to tinker and try something, can plunge into the world of Linux and programming. In addition to programming, the RasPi can also be used to realize other projects such as a 🔗 http(s) web server or a 🔗 dedicated game server.


No prior knowledge of Linux or any programming language is required. With the necessary curiosity the existing gaps in skills can be filled. People who are already dealing with the matter master the Pi very fast.


Even multiple projects can be tested simultaneously on a RasPi, because the operating system is installed on a microSD card and can be exchanged for another with another operating system in seconds. In addition, the Raspberry pi gets stronger with each version. At the same time, the computer in credit card format remains very energy efficient at low costs over the years. 💚 = 🌳


PuTTy terminal Linux

PuTTy logo

Please note that here 🔗 PuTTy SSH terminal is used for $bash command line.

PuTTY is an SSH and telnet client, developed by Simon Tatham for all Linux derivates & MS Windows. macOS includes its own command-line SSH client as part of the operating system.

user@raspberry:~ $ sudo su
root@raspberry:#

Linux is fundamentally more secure than competing operating systems. The development through a free community is less driven by economic constraints and no services are imposed on the user. As a result, Linux can provide a secure foundation for advanced privacy protection without requiring the full attention.


At the moment, both Windows and Android are not recommended. This is due to security issues and a potential threat of malware, as well as the lack of appreciation to privacy.


Recommendations are always difficult to give the right perspectives of operating systems. Personal preferences, ideological contradictions and technical limitations hinder objective recommendations. With regard to the appreciation for data protection by the developer community or company, however, Linux distributions and the two systems from Apple macOS and iOS can currently be recommended.

The minor relocation | From no-cost dynDNS to own SLD server


Relocation | From no-cost dynDNS domain server to own SLD domain server From now on this web server runs under my own Second-Level-Domain (SLD). Extra expenses per month: some lousy 60 cents euro. My former dynDNS provider noip @ no-ip did show up with too many downtimes & dropouts.

Right, at least it was off from any monthly fees. 💰
Nevertheless I have made my assessments because dynDNS providers give more or less a set-and-forget setup.

🔗 Read various arguments in favour to this decision.


Estimated calculation of costs for the first year of acquisition.
Most Pi run headless and is controlled over SSH. It doesn't need a keyboard, mouse and display.

Raspberry pi + shipment 40€
LAN-cable 5€
5V power supply 5€
microSD card 10€
Domain registration per year without webspace 15€
Energy consumption per year at 4Wh (0,004kW/h x 24h x 365 x 0,25€ per kW/h) 9€
------------------------------------------------------------------------------
Total costs around 84€ estimated.

To the second year of life around 24€ only (domain & energy).
And you get unrestrained access to /root to fire up a http(s) server in any configuration.


Extra fees for SSL 🔒 - https:// - are not considered.

Come to the Duck side.

Duckduckgo Duck


Get off from Google's online services


At first we have to point out that Google Inc. is not only a search engine for us all. Google Inc. is a company made for advertisements and harvesting peoples habits throughout World Wide Web. 2018 was an eventful year for Google Ads.


Google Inc. on the other hand tracks us a lot. Considering they own Blogspot, Gmail, YouTube and many other big platforms they can collate a lot of information about us by our browsing habits.


By the end of the day you have to decide how comfortable you are exchanging your data for things/services. Surveys show people are happy to share their data if it means they get a better and personalised service. Some are not. Those people probably use alternatives. Irony is, a lot of people probably use it via the Chrome web browser. Guess who owns that?


... Due to the lack of appreciation to privacy Google's Chrome browser is not recommended.


A couple of 🔗 Google alternatives are ...


DuckDuckGo : became my favourite search engine. The key feature of 🔗 DuckDuckGo is that it doesn’t retain its users’ data, so it won’t track you or manipulate results based on your behaviour. So if you’re particularly spooked by Google’s all-seeing eye & all-knowing brain, this might be the one for you.

StartPage : Another search engine that puts privacy at the forefront, 🔗 StartPage (originally known as Ixquick) was the first search engine to allow its users to search privately.

Qwant : 🔗 Qwant is a web search engine, launched in July 2013 and operated from Paris, France. It claims not to employ user tracking and doesn't personalize search results in order to avoid trapping users in a filter bubble. It is available in 13 languages.

Creative Common Search : 🔗 CC Search is particularly handy if you need to find copyright free images. Type your query in then click on the chosen site you want to search.

Quora : As Google gets better at answering complicated questions, it will never be able to match the personal touch available with 🔗 Quora.

Dogpile : 🔗 Dogpile may look like a search engine you cobbled together with clip-art, but that’s rather the point as it pulls in and merges results from various search engines including Google, Yandex and Bing/Yahoo, but it removes all the advertisements.

Vimeo : Of course if you’re planning to give up Google soonly, then you’ll also have to give up YouTube soonly as well, which can be a terrifying prospect. 🔗 Vimeo, the professional’s choice of video-sharing site, which has tons of HD videos and lesser advertisements.

Nextcloud : 🔗 Nextcloud is an open source, self-hosted file share and communication platform. Access & sync your files, contacts, calendars & communicate and collaborate across your devices. Decide yourself what happens with your data, where they are and who can access them.

Commento : Privacy-focused commenting platform. 🔗 Commento has not, does not, and will not gather your personal information to sell to advertisers, third-party trackers, or other organisations. Commento is one of the recipients of the Mozilla Open Source Support.

Unsplash : 🔗 Unsplash is a website dedicated to sharing copyright-free photography under the Unsplash license.


It's your choice.
