Software Engineering != Computer Science
Software engineering is the process of analyzing user needs and designing, constructing, and testing end user applications that will satisfy these needs through the use of software programming languagesTechopedia
Computer Science is the science that deals with the theory and methods of processing information in digital computers, the design of computer hardware and software, and the applications of computers.https://www.dictionary.com/browse/computer-science
Computer scientists are not necessarily software engineers, and unfortunately many software engineers don’t necessarily know much about computer science. Software engineers are focused on building products, and writing maintainable code and architecture. Computer science is comprised of the fundamentals that software engineering is built upon, and by understanding more about CompSci, we can be much better engineers.
A Shift in Front End Development
Front-end development has really come into the limelight over the last decade, with frameworks like React, Angular, and Vue.js championing that movement. A lot of functionality that previously was provided by server-rendered template pages (PHP, Django, Rails) now exists as a decoupled front-end bundle.
This is fantastic news for a couple reasons. First, I’m of the mindset that this decoupling is a good architectural decision. Second, it means that front-end developers take on more responsibility, which allows them to become better engineers and earn more monies.
Nowadays, front end developers need to have strong logic and programming skills not only because they will be required to handle more logic in the browser, but because there is a high chance they will be asked to do server work in Node.
Learning the Fundamentals – What to Start With
There are millions of topics in the computer science field, and no one understands them all, but below I’ve listed some good starting points.
Big-O deals with time complexity. In other words, how to keep programs fast. By learning about algorithm speed, we understand how to sort data for display, utilize databases for better performance, make applications more responsive, and so much more!
We also learn how cryptography and security work on the internet, because they deal with keeping encryption fast and brute-force decryption slow.
What are the stack and the heap? Pointers? Memory leaks? If you have never worked in a compiled language like C++ or Go, I would recommend doing a pet project or two.
How does a processor know to take the expression:
5 + 3;
and add the numbers 5 and 3?
Who taught the processor to understand the Arabic numerals? The answer of course is that it doesn’t, processors only work bitwise, on binary numbers.
Assembly is the native language of the processor, and writing a bit of it can really help us understand how the CPU processes stuff. Because assembly is so tightly coupled to CPU architecture, the language changes depending on the processor type. I recommend starting in ARM, it has a more elegant syntax than x86 in my opinion.
Ever wondered how computers do multiple things at once? In most programs we write, there is a simple flow of logic, everything happens sequentially. If we are writing code that runs in the browser, then most code is fired based on events, but the fact remains that two instructions are never ran at the exact same time.
Threading is the practice of utilizing multiple processors, or processor cores, to do computations at the same time. Threading is a powerful but dangerous art. Threading allows us to speed up our programs by using the computer’s architecture to our advantage, but can introduce bugs like deadlocks or race conditions.
Writing a toy program in Go and making use of virtual threads, called goroutines, is a great way to get your feet wet with threading.
Thanks for reading! I hope that learning more about some of the concepts I’ve outlined will be useful to you in your career!
