Readable, clear code is critical. You write your code once, but it will be read dozens of times. Writing for readability will save you LOTS of trouble down the line (which will also save a lot of time). If you EVER go back and read your code and have to think about it for even a second then you're doing it wrong.
Henneke, I can’t tell you how much helpful this post! I have learned a lot from this post. Avoiding rabbit holes is a big one for me. I just need to just avoid what’s needed to be added while I’m writing because as you said, the momentum to write or the motivation to write just breaks when we get off the writing pad and put our brains into something else.First get wet with the basics. Learn the gotchas, learn a good C style. You can't learn how to write efficient C code in one run, so it's okay to make mistakes in the beginning. I found the best way to learn how to write efficient code is to learn how to avoid memory leaks. Maintainable C code requires good documentation and comments in the source.Write C code that is correct, faster, and easier to maintain by understanding the C standard and what optimizing compilers can do for you automatically --- and what you need to optimize yourself.
One of the counterarguments that you constantly hear about using python is that it is slow. This is somehow true for many cases, while most of the tools that scientist mainly use, like numpy, scipy and pandas have big chunks written in C, so they are very fast.For most of the geoscientific applications main advice would be to use vectorisation whenever possible, and avoid loops.
Functions: Make functions of your code and although procedural code is supported in Python, it’s better to write them in functions. You might have heard this advice from proponents of code reusability and champions of TDD (Note: I am one of them), but here I would say that functions are better because they are faster.
How to write fast code There was a time, early in my programming career, when I needed to rewrite a particular program (a very small one) to make it run faster. I was quite new to programming and thought that the way to get something to run faster was to rewrite it in assembly.
I hope this guide can help you understand how to write code faster. We have compiled some great tips from successful developers to help you type code faster. Using programming tools like TeaCode is a good way to start, but in the end, it’s only practice and focus that will help you stay consistent.
Because they dictate every detail of execution, the very best assembly-language programmers will always produce faster-than-C code. However, good programming techniques combined with exploitation of the power of the C language enables you to write code that is easy to understand and modify, yet runs as fast as stuff written by all but the most experienced assembly programmers.
The above code rounds x to the nearest integer, but if x is exactly equidistant between two integers, n will be the nearest even integer (for example, 0.5 generates 0, 1.5 generates 2, -0.5 generates 0, and -1.5 generates -2). If this result is tolerable or even desired, and you are allowed to use embedded assembly, then use this code. Obviously, it is not portable to other processor families.
Tutorial and example on how use Docker Host Volumes and nodemon to write and test your code faster during development.
Use byte code compilation for functions cmpfun() from compiler package, rather than the actual function itself. This may not be the best example to illustrate the effectiveness of byte code compilation, as the time taken is marginally higher than the regular form. However, for more complex functions, byte-code compilation is known to perform.
As the compiler translates your C code into object code, it checks for common mistakes, missing items, and other issues. If anything is awry, the compiler displays a list of errors. To fix the errors, you reedit the source code and attempt to compile once again.
This book has given me a lot of knowledge on what are the best practises and how to actually write code. Now I feel ashamed of my coding skills. Though I always strive to better my code, this book.
Are you asking for an algorithm to type faster?? You're not a machine haha! It takes practice. A lot if it. Try being bold. Sharpie over your keyboard. Rearrange your keyboard, and learn how to type with the Dvorak layout. Dvorak Simplified Keyboa.
Some ideas (in order of complication but also performance benefit. Start at the top and work your way down until you are happy with performance): 1. Use proper data structures and algorithm for the problem at hand (using dicts or lists incorrectly.
The point is to increase work-flow (efficiency), which means you can create declarative (readable code) commands, that is easy-to-remember and quick to write. Keep in mind, that the idea is not to create aliases for every terminal command out there, but the ones you repeatedly use.
Where it is needed? Without this point, no discussion can be started. First and the most important part of optimizing a computer program is to find out where to optimize, which portion or which module of the program is running slow or using huge m.
