## 2026-01-13 - Reading a little bit ## 2026-01-14 - Nand2Tetris Unit 2
**Tasks:** Only read a little bit about C. Did some git setup on my laptop. **Tasks:** Watched the whole Unit 2 on youtube.
**Blocker:** Time was pressed today. **Blocker:** Nothing really. Understanding if anything.
**Discovery:** Multiple git users on the same laptop. Also learned of a selfhosted gitea solution. That works very good. **Lesson:** Learned about the ALU(Arithmetic Logic Unit) and what it is used for and how it is built. Learned of adding/substracting binary numbers. Binary to decimal conversion simple.
**Lesson:** C information and gitea selfhosting. **Tomorrow:** Trying to implement the ALU in HDL. Will start the Project 2 tasks.
**Tomorrow:** Reading nand2tetris unit 2 text **Time Spent:** 90m

**Blocker:** They were hard to understand at first. The logic is not quite there for me. Hope that it later will make more sense. **Blocker:** They were hard to understand at first. The logic is not quite there for me. Hope that it later will make more sense.
**Discovery:** A little bit of a realization of how the logic gates work together. Still a bit fuzzy. dMux4Way and all that. **Discovery:** A little bit of a realization of how the logic gates work together. Still a bit fuzzy. dMux4Way and all that.

**Task:** Implementation of the HDL logic gates. **Task:** Implementation of the HDL logic gates.
**Blocker:** The logic behind it. The coding mindset. Need to change the mindset a bit to be more systems hardwiring. It's okay. It's a process. **Blocker:** The logic behind it. The coding mindset. Need to change the mindset a bit to be more systems hardwiring. It's okay. It's a process.
**Discovery:** Learned about a web tool that helps build the logic implementation. It clicked a little bit with the gates and creating valves instead of doing if statements in my head. **Discovery:** Learned about a web tool that helps build the logic implementation.

**Lesson:** HDL scriping/coding. Built And, Or and Xor gates. Wrote them i guess. Had a hard time understanding and planning the implementations. Had to look some of them up on Wiki. Not the HDL solution. Only the diagram. **Lesson:** HDL scriping/coding. Built And, Or and Xor gates. Wrote them i guess. Had a hard time understanding and planning the implementations.
