I have watched the Udacity Git Course and it was awesome!!! I've already had experience with Git but it was great to have an opportunity to learn some new commands.
I have passed the Linux Survival Course and I had many things to learn there. The knowledge I got will be necessary for me in the future so I'm glad to have got it.
I have watched the Udacity Git Collaboration Course. It was more difficult than I thought. However, now I know how to use Git and GitHub for teamwork. That knowledge is essential for any IT specialist so it's excellent I have it!!!

What's going to happen if program reaches maximum limit of stack? Answer: there will be stack overflow error and the program will receive Segmentation Fault. But if the stack is dynamic we will be able to access to an unmapped memory region.
What's going to happen if program requests a big (more then 128KB) memory allocation on heap? Answer: the heap will be enlarged via the brk() system call (implementation) to make room for the requested block.
What's the difference between Text and Data memory segments? Answer: Data Segment stores the contents for static variables initialized in source code. The text segment is read-only and stores all of your code in addition to tidbits like string literals.

The courses were really interesting and I've learned a lot of new things. I've never thought that there are wires under the Ocean. I used to think that it was the "power" of wireless Internet. My new knowledge is priceless for me.
- Name at least three possible negative consequences of not using https.
- Other people will be able to eavesdrop my connection.
- Other people will be able to intercept and update messages I send to server from my browser.
- Server and my browser won't be able to recognize each other. Thus, I may get on absolutely wrong site.
- Public key is used in assymetric key algorithm. Public key is used to encrypt messages while the private key is used to decrypt them. My browser uses the server's public key and encrypt my message for server with it and server uses its private key to decrypt my message and vice versa.

It was rather interesting but the course turned to be really big. It took me much more time than I expected
