On the video description, rust is added in the list of programming language. first question: When it comes to embedded systems in vehicles and other machines like in the agricultural sector will Rust work just as fine as C++ second question: Is it advisable to learn Rust instead of C++ right now.

Great vlog about tech in SA! I wonder what programming languages are prevalent in the various sectors that drive the economy of my country. Us we are mostly consumers and maintainers of other countries technologies because we do not believe in home grown solutions save for a few exceptions.

Lovely video! This topic has preoccupied my mind this morning. You briefly touched on C# in the tech industry, Id like to know more about its use-cases and adoption in industry. I'm currently doing my 3rd and final year in IT and I've noticed a great uptake of C# as opposed to Java in ITvarsities. Research does indicate that Java is the dominant language when it comes to ERP systems and backends so it begs the question, why are technical colleges(especially private ones) teaching C#?

I do not agree that Java is main language used for backend in SA, by looking at job postings alone one can see C# posts are way more then Java
@davidtech024
@davidtech024 4 күн бұрын
Thank you for your input! I understand where you're coming from, especially when looking at job postings. It's true that C# has a significant presence in certain sectors, particularly in environments leveraging Microsoft technologies. However, when considering the broader banking and financial services industry in South Africa, Java remains a key player due to its proven scalability, security features, and longstanding presence in large, transaction-heavy systems. While job postings may reflect the immediate demand for specific skills (such as C# in certain contexts), Java continues to be the preferred backend language for many core banking systems and enterprise-level applications in the financial sector, which require robust and scalable solutions. It’s also worth noting that many large financial institutions use a mix of technologies, including both Java and C#, depending on the specific needs of their systems. So, in terms of market trends, both languages are important, but Java holds a significant role in industries where high-volume, secure transactions are critical.

I’ve worked in many sectors, currently focusing on Ai and real-time systems: I’m mainly using C++, Python and JavaScript. From experience and talking to other developers: -In Trading: Python,C++ and Java(in some companies). Python is mostly used for building strategies, backtesting etc and C++ for trade executions. -Insurance: Java, Python, C++ -E-Commerce: Python(Ai), Node js, Java -Banking: Python(Ai), Java , C++ -Mobile Apps: [Swift, Kotlin, Java] for OS-based apps and [Flutter, React Native] for cross-platform apps. I’d recommend learning: -Python: For Ai, automation and fast prototyping using FastAPI or Flask or Django framework for web backend -C++ or Java for backend design -HTML, JavaScript for frontend With Ai, the complexity is in understanding the maths behind the models. You need to be clued up with Calculus, Statistics and Linear Algebra. Without that you’re wasting your time. To stand a chance of landing a job, build a portfolio of INTERESTING projects that solve real problems, and UNDERSTAND their design. If any questions, let me know below. All the best!

Not important at all, focus on the field you're interested in , for example if you're looking at being a web developer, start with HTML, CSS and some JavaScript, make sure you grasp the basics very well. From there you can choose a backed language, I'd recommend PHP, bundle that with MySQL to build data driven web apps

I probably know what you're thinking my guy, these American CS majors are jobless, would it still be a good idea to study it? YES, consider that America/Europe are developed countries, their job market requires specialized roles because they are that advanced with their tech, so studying CS in a developed economy is swimming in the deep end unless you really stand out. South Africa's tech industry is still developing so generalist roles are still needed to match the pace of the market.

It depends where you want to work. South african companies still use quite dated tech stacks. GitHub portfolio means more than years of experience. My friends in America are in their 1st year at university and can build full stack web apps with enterprise standards. Devs In South Africa so the same thing for 15 years and handle one small aspect at a big company and think that it's experience. As a software engineer , you're worth lies in the things you build that nobody tells you that you need to build. No GitHub portfolio , probably not that good at high level tasks

Aah, I actually missed this one, for those who might not know "FMCG stands for - Fast-Moving Consumer Goods". This sector is heavily reliant on technology and these are the programming languages used: SAP(Java): Often used in backend systems for supply chain management, e-commerce platforms, and enterprise resource planning (ERP) systems due to its scalability, security, and robust frameworks like Spring. Python: Popular for data analysis, machine learning, and automation tasks. JavaScript: For frontend SQL: For DB querying C#: Mostly used in environments that integrate with Microsoft technologies (e.g., for ERP systems or inventory management systems).

Portfolio projects won't get you that close unless it's luck. I always recommend people to build a SaaS or micro SaaS. You can always try to solve a problem or clone products that already exist especially B to B solutions e.g payroll system (scheduling, tracking hours, employees onboarding and management etc provided that it solves an existing pain point. There's quite a lot of solution you can build and sell online while using them to showcase your skill(s)

@DavidTech whats your take on Low code development such as PowerPlatform?
@davidtech024
@davidtech024 7 күн бұрын
"Great question! I didn't know about PowerPlatform and had to do a bit of research and I came to this conclusion and the guys who work extensively on this can chip in: Low-code platforms like PowerPlatform are definitely making waves in the tech industry. They allow developers (and even non-developers) to create applications quickly without needing to write extensive code. This can be a game-changer for businesses looking to streamline processes or rapidly prototype ideas. For developers, it’s a great opportunity to expand your skill set and work alongside business teams to create solutions. However, while low-code platforms can accelerate development, they may not replace the need for traditional coding in more complex applications. It’s all about knowing when and where to leverage these tools effectively. Thanks for asking!"
