I've used "Data Structure and Algorithms in Java" by Goodrich, Tamassia & Goldwasser. I used the Java one but they wrote other books covering a lot of other programming languages. Really good book, the arguments are well explained and made easy to read and understand. It starts with a little bit of theory about the language, recursion, analysis methods. Covers the arguments very well, by presenting the Abstract Data Type, pseudo code for all of them and even a Java implementations like 95% of the arguments. Helped me a lot in uni, the book alone did a much better job than my DSA course lecturer and I still got a really good mark.

They are 22ohm resistors. You can see they are resistor by the marking R on the pcb. The first two digit is the value (22), the last is the multiplier (0), so it would be 22*10^0 =22 ohm

My Anet A8 lacked the aluminum bracket to which the extruder is mounted. Luckily I got refunded in total, got a friend to print me an E3dv6 carriage and went with bowden setup. I haven't had but problems with that printer, I spent more time fixing it rather than using it in the past two/three years. There is always something not working, something about to break, something to be repaired. The board and the heated bed are an heat hazard, I've personally seen a friend's a8 coming with an extruder which would clog every couple minutes. The frame is not stiff and vibrates a lot, the stock carriage is barely held up by the two z axis motors, weighs a ton and often unalligns itself during the print. Different extruders would randomly clog even with esteps and flow calibrated and no heat creep.

I got mine for 100€ and got refunded in total because a crucial piece was missing, but for 200€ you're better off waiting for a nice offer on a ender 3. I wouldn't recommended thatprinter to my worst enemy.

Also nice that my first lemmy comment is me crapping on my anet a8.
