Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

ich hatte weiter vorne ja schon mal davon berichtet, dass in mein 2010er MBP schon der dritte Akku werkelt, da die Teile immer wieder schlagartig altern und die Kapazität einbricht. Der aktuelle Akku war bislang der beste, doch nach 2 Jahren Betriebsdauer und knapp 160 Ladezyklen ist gestern die max. Kapazität von 80% auf 45% gesunken. Da ein Kalibrieren nichts bringt (im Batterie-Menü wird das Wartungs-Warndreieick angezeigt) steht jetzt wieder eine Neuanschaffung an. Da ich nicht schon wieder ein Vermögen für einen Original-Akku ausgeben möchte, der vielleicht wieder nach einem oder zwei Jahren den Geist aufgibt, habe ich mich nach Alternativen umgeschaut, und bin auf eine günstige Alternative von Net-Electronics gestoßen: http://www.akkuswelt.com/akku-compaq-cq71.html
Mit dem optischen Schönheitsfehler, dass die Außenseite nicht aus Alu ist, könnte ich leben. Hat evtl. jemand von Euch Erfahrungen mit Akkus dieser Marke in Bezug auf Kapazität und Haltbarkeit? Oder gibt's eine andere erschwingliche Alternative zu einem Original-Akku?
I had earlier times already reported that in the 2010s my MBP already tinkers the third battery as the parts age again abruptly collapses and capacity. The current battery has so far been the best, but after 2 years of operation and nearly 160 charging cycles yesterday the max. Capacity of 80% decreased to 45%. Since a calibration does not help (in the battery menu Dreieick the maintenance warning is displayed) is now back in a new acquisition. Since I did not already want to spend a fortune for an original battery, perhaps after a year or two, give up the ghost, I looked around for alternatives and came across a cheaper alternative of net Electronics:
With the optical flaws that the outside is not made of aluminum, I could live. Has anyone of you any experience with this brand batteries in terms of capacity and durability? Or there's another affordable alternative to an original battery?

I have never used those batteries, but I have used aftermarket batteries that are designed like them. In my experience, they're not going to last quite as long on a charge as a proper battery (they're not made with quite the same level of quality), but they'll last just as long before they start to degrade.
However, IMO, it might be worth it to simply replace the laptop at this point. That model isn't exactly young, and I can notice the difference in performance from my older T9600-based laptop (that is far more powerful than the "base" processor in that model) to a couple generation old core i5 2520m. Compared to the 3360m that I just got, it's actually quite a large difference in performance.
