What is Git and what is it used for? What is the difference between Git and GitHub, or GitLab?
In this lightboard video, Nathan Hekman with IBM Cloud, answers these questions and much more by using an example of a media streaming company that has two developers who need to write code at the same time on the same code base without conflicting with each other in order to build a new music streaming app.

Nathan, Great job. Plus I also bluegrass so that gets u another star. In comments Singh Noah asked a critical. Read Anton T wrote a very informative reply. While I do not use IBM Cloud, they do provide excellent tutorials.

[@TonyJose9162007]

I wonder how you people have matched Hekman's hand movements with the writing in inverse on the screen. I find this technology truly amazing !! I MEAN WOWW!!

[@AP-eb8hd]

the concept of lightboard works on special glass... used for writing and then mirrors to invert the image.

[@AP-eb8hd]

Or you can software to reverse.. if its not online real-time streaming

[@carsten2600]

I never understood why ppl called it PR, but now I can understand it, thanks!

[@duroskylala]

Nathan, I have a question on this video. At the end of your example, why did you do a Push and not a Pull and Merge?

[@freqtion]

beautifully explained

[@nmartin32950]

Excellent vid. Just some quick questions which are probably obvious to everyone else: 1) How does Greg know a PULL-MERGE is required, did a PUSH attempt fail? 2) Does Git interrogate and analyze the code inside the file and highlight the specific conflicts or is it just file name, file size and timestamps? 3) Does GitHub/Lab automatically push a notification to whom ever is responsible for answering the PULL-REQUEST? 4) Is there a part two vid clearing up the Greg stages of interaction with the main branch?

[@adalovelac24]

did you find answers ?

[@semihozkan8514]

@@adalovelac24 did he/she find answers?

[@adebiyial]

I can help you here. 1. Greg can tell if he has to pull the code from the main branch by checking the GitHub repository to see if there are new changes. Or, more ideally, if Greg tries to push to the main branch, GIT is smart enough to know that there is a conflict. So GIT will say something like: Greg, you are trying to push your changes to the main branch but the main branch has some changes you don't have. Please pull first before pushing. 2. Git does a lot of things to check if there are changes. Take two files for example, A and B. As long as they are two different names, there is no similarity even if they have the same content. If they have the same name, GIT can check it's own copy (usually the latest copy) and cross check the new copy. It checks line by line. If both files have the same content, then nothing changed, if they don't, GIT will show you something called a "diff". A diff is just GIT telling you the difference between each line of code. If line 1 of the file GIT has is different from line 1 of the file Greg is trying to merge, GIT will tell Greg: There's a conflict. 3. PR has their own rules. Ideally, you as a user that started or opened a PR can choose to notify someone to take a look at it, or you can leave it there until the person comes to check. It's all about notifications, no hard rules. That's not GIT's responsibility, it's GitHub.

[@srlhyo]

@@adebiyial but buddy, here is one thing it wasn't clear to me: "knowing there is a merge conflict from pushing the code and git telling there's new code on github I don't have, is making a pull request a way to avoid dealing with the merge conflict? I mean, if I make a pr then I don't need to bother pulling any changes?

[@iaphlnt]

@@srlhyo A pull request isn't going to resolve any conflicts, you still have to do that yourself. The only thing that can happen is you pull and handle the merge locally or force a push and delete any changes that were made, probably not a good thing to do

[@kevinedmond6507]

Hello good morning Nathan! I have watched your video regarding GIT, at present, I am a student of Data Analytics, can I use GIT as my repository for my studies? Thanks

Your videos are very useful for me. But, allow me to add one note. You write the notes in two colours, one is bright and clear for me. While I have a problem with the other colour. Thanks again and I am sorry for the out of subject note.

Can you do blockchain video Not the basic Just like zkp , IPFS , how wallet actually work , rules of blockchain development ( longest blockchain rules , POS And ect ...) .... So i would be great for me and my university students By the way thank you very much fir this great explain ❤️

[@ilostIneurope]

Great video

[@JosePayano]

Thanks Natham! Truly appreciate the straightforward way you use to explain what otherwise would be a complex subject... MY QUESTION: Which, I think you didn't mention is 'why are these platforms called "GIT"? I don't see any related meaning to 'Version Control Systems'. What exactly is the origin of the Acronym?

[@IBMTechnology]

According to Wikipedia... Torvalds sarcastically quipped about the name git (which means "unpleasant person" in British English slang): "I'm an egotistical bastard, and I name all my projects after myself. First 'Linux', now 'git'." en.wikipedia.org/wiki/Git#Naming

so good man

[@TheGloriousRussian]

I'm a little bit confused why for Greg it's called Pull Request but not Push Request isn't he is pushing his changes to the GitHub repository as Nathan did before?

[@milanturkey]

Das Quietschen der Stifte bringt mich um, aber tolles Video!

[@alphabeta1521]

An excellent video. Learnt a lot. Thanks. But.... please tell me how do you make this type of videos like writing on a glass...?

[@IBMTechnology]

Hey! Glad you enjoyed the video! 🙂 As for the making of, we explain it all in our "Community" section 👉 ibm.co/37r6z8h 🧐

[@landertee]

I can't stop focusing on how good Nathan can write backwards

[@pragatibansal9492]

Great video😁.. I have a doubt does grey have to do all its work again after pulling the updated code

[@username-1043]

No. He just has to resolve merge conflicts which will be visible on Greys' code. He can keep all , some and none part of the pulled code.

[@TwstedTV]

@@username-1043 Also due note, that just because you make a Pull Request (PR) doesnt mean it will get accepted. It can be denied for any reason. It will get denied by whomever is in charge of overseeing the github project. I say this, because some people have the sense of belief that they can just put up any code they want. which is not true. It goes through an approval process first.

Quick question, could Greg have been able to do the same with a Push request ? When should one do a git Push vs a git pull request ?

[@dheerajgupta15]

Following.

[@subbamaggus1]

@@dheerajgupta15 my expirience is that greg and nathan push their branches to the main repo. so that both info is there in gitlab/github. and then you create a pull request (so everything is done on the server). afterwards you merge the main branch to your local repo, and then push. and create a second pull request on the main repo. sounds right?

[@syedahmad5655]

Thanks. Quick question. How is code in Git repo put together and what is a build process?

[@brendaninsiima4791]

Thanks Nathan, So can I use GitHub to create educational audio and written material for the youth and public in general. As an aspiring book & article's writer etc, Bible teacher and motivational speaker, how can Git help increase my viewer's in number in order for them to acquire this knowledge? Thank you again.
