What Does Large Scale Software Look Like?

[@goosybs]

Lemme add my experience with companies: Usually they have their own hosted git solution (like a gitlab instance). Then the team works with some kindof process (like Scrum). So then someone writes all the issues and "backlog" items that should be done (like bugs, features, ...). Then you plan what to do next (in a team usually) and developers can start implementing it (moving item to progress, opening branch, opening MR/PR, giving it a good description, implementing (passing all tests, requirements), other dev will then review/give feedback, then its merged (often into a dev branch and not the production branch), the dev branch is connected to a CI/CD pipeline and result is hosted on a testing version of your product, then the testers jump on it and test manually, pontentially moving the issue back to the developer where they start with implementing the fix(review->merge->test)) until the testers are happy, then it can be planned into a release and eventually released (where all production server will be updated). In that whole process its often a thing where requirements arent clear so youd have to ask the one who wrote the requirements, or the tester might have questions to the developer, and many other communication that can delay the progress of a feature being implemented. Thats why big companies often take very long to finish things.

Amazing expiation man! That’s some great insight into deeper level stuff that many of us haven’t reach yet so it’s awesome to see what it could be like one day :)

@@sam-pt7rt why are you job hunting in a replies to a random youtube comment

[@heyarvee]

can confirm, this is large-scale, production grade code because there is tons of code but no comments.

[@NizzyABI]

lmao

[@Jarvis2077]

Yeah same thing in the company I work. No comments.

[@shyshka_]

comments are useless 90% of the time

[@Jorma___]

If you need comments, then your naming is terrible or your code is over complicated

[@angryktulhu]

@@Jorma___ nope that's popular WRONG statement. Actually comments help a lot and often substitute the docs. For example, the docstrings in Python can easily explain things very well - so you won't have to create a separate technical docs, README, anything. It's a big question what's better - tech docs or code comments - because they are basically very similar things and serve the same purpose. But saying that you don't need any of them, and the code itself is enough, is utter BS. Try to onboard a new developer on a new huge codebase with no comments and no docs. Good luck having him/her lost and unproductive for at least 1-2 weeks. That's just a waste of time and money

[@Peeeeeew]

Usually there's ""Grandmaster Agile Scrum Blackbelt Ninja Overlord of Kanban, Certified Professional Extraordinaire in Synergistic Waterfall-Agile-Hybrid Methodology, Supreme Overseer of Gantt Charts and Timelines, Archduke of Sprint Planning, Commander of the Infinite Backlog, Emperor of Deadline Extensions, Master Conductor of Stakeholder Alignment and Scope Management, All-Seeing Eye of Budgeting and Resource Allocation, Guardian of Milestones, Wielder of the Holy Project Charter, and Divine Protector of All Things Asana and Jira" project manager who makes the whole process of code-production 1000 times slower.

[@jackpaulcollins]

You don’t only write tests to avoid bugs in your commits, but to prevent future commits from breaking what you wrote

[@adammouaddine8866]

[@Schwein41]

AND making new features/refactorings/dependency updates easier, as, if you can run the tests from unit to e2e, you can be somewhat sure that everything still works. Ye

[@SiimKoger]

Tons of security measures, auditing tables, tons of monitoring, i18n, custom UI elements, rigorous testing, different styles of code even after linting, data migrations, library and framework verion updates, ... the list goes on. Joining a big company that has decades of legacy to it is a complete different beast than anything you could do or would need in a hobby project.

[@NizzyABI]

I bet! The company I work at is just a few years old so the code is at least somewhat relatable to my side projects but I bet the larger company code must be much much harder to use

[@permanasibarani6966]

Sounds like Magento 2 😂

[@zapking4244]

This was really nice to see. I've never worked at a company yet, but I'm about to graduate with my CS degree in a few weeks and getting some insight on larger companies is really helpful! Also this is for you - 😘😘

Super interesting video, as a dude who mainly codes for fun since I mainly work in Excel and never seen any large scale project, I really apreciate this video

[@joemalatesta9883]

Honestly a banger overview. There is a lot to be said on the infra part as well. CI/CD actually becomes necessary and consistency in linting/formatting somewhat matters too

[@josephperkins-z7n]

Hey Nizar, Been in a programming rut of recent, Happy to see your still around. I'm gonna just feedoff your programming rizz and energy and get back on my A game. Srsly, Thx for being an amazing developer and friend. Also 😘😘

[@NizzyABI]

Glad to have u back bro!!!

[@itsbare5172]

I am still pretty early in my career have worked for a large cap company and now a small cap. I think the biggest thing that threw me off when first seeing industry code is the sheer amount of custom objects/types. I worked mainly on backend microservices and you can't just pick up a ticket go to that endpoint and find the bug these things are using like 4-8 custom types that each have their own logic, the amount of nesting that you have to sift through to even get to the base definition is 2-4 layers deep a lot of the time and you do this for all types to even understand what the piece of code is doing.

well it's not even a BIG company. In the big companies, inter-department communications become more and more common and eat time. Like, you have to write and document how all your team's microservices work, and don't forget to update these docs, because a bunch of other IT teams rely on them

I hate seeing comments that say something like ”Here I loop”. I can see there’s a loop. One comment said something like ”stop fooling around, let’s do some work”. So, all you did until this comment was to ”fool around ”

[@NizzyABI]

comments themselves are sooo annoying the code itself should speak for itself for the most part

[@TheFrewah]

@@NizzyABI It should but it doesn’t always do. 99% of the time, the first person to fail to understand how or why some code works is the person who wrote it because the clever parts lacked a comment.

I only write comments for things I can't change and always explain WHY the code is there instead of how or what it's doing.
