I think the right answer would be the one that is actually correct. with writing imperative code (even Code Grouping. The question is about maintainability. As it currently stands, this question is not a good fit for our Q&A format. They will probably both throw null reference exceptions. Also, losing performance at the cost of readability can happen only to some extent. We just need to compare the code generated by VB Migration Partner with the code coming out from a “traditional” VB6 conversion tool that has a less extensive support library. It's an economic negative externality, similar to a form of ignored pollution. Remember that in classic C, the only difference between a "string" and an array of characters is that terminating null character '\0', so we had to more actively treat them accordingly and to make sure that we did not run off the end of the array. I cant access. +1 because this ain't C, and I even like C. @Dinah, consider a person who's done Java but looking at some C#. More the readable code, greater the chances of having easier to modify, less mistakes, more maintainable, easy to reuse, and more reliable. ), https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585751#2585751, Are you certain #1 is faster? Different groups of developers were asked to optimise for speed, memory usage, readability, robustness and so forth. Maintaining the codebase is time-consuming and not many developers like to do it because it lacks creativity. Here's the most famous I think. Further, I've managed to beat such algorithms and data structures with more straightforward code relying on general computer science and computer architecture knowledge, not cutting-edge industrial algorithms published by mathematical wizards, that "theoretically" didn't scale quite as well (ex: linearithmic vs. linear) but were micro-tuned, and my version required only about 1/100th of the code the scalable solution required while being faster for larger inputs (relatively faster the larger the inputs became, making my version even more scalable in practice even though it was less scalable theoretically). Reliability is the wellspring for the other RAM system attributes of availability and maintainability. But, like beauty, readability lies in the eyes of the beholder. You test and document like crazy here, you know it's going to hurt if you have to do any maintenance in this code, but you have to because performance is absolutely critical. After a certain point, you have to resort to "real" means like better algorithms and hardware. thanks though! We've worked on a lot of code that, to address performance issues is VERY complex. 2. Sign up to join this community. inspiration is the association of code readability and software maintainability. https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/362255#362255, "Micro-Efficiency" is sort of like saying "There ain't no such thing as O(1) memory access", https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111190#111190, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/147820#147820, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/148026#148026. Proper formatting increases readability and hence maintainability, and also give readers the impression that the code was written by professionals. More - [ ] Added/updated tests - [ ] Added/updated documentation Additional Notes Co-authored-by: Ludovic Fernandez email@example.com better, then you have not improved and And I am talking here about high level languages. Using a lot more classes and methods to improve code readability and maintainability Minimized duplicate code Improved Fork-ability by using variables everywhere possible (Plugin name, version, permission, commands are mostly based on a value configured in pom.xml And arguably algorithmic optimizations are more difficult to maintain than micro-optimizations. Optimizing code for performance often makes it more complicated because it generally involves doing things in a clever way, instead of the most intuitive. The second example is telling me the intent. Why: Improve readability and maintainability by removing code that is superfluous and will never be executed. In that order. @KeithB - you make a good point, I will add it to my answer. In computer programming, readability refers to the ease with which a human reader can comprehend the purpose, control flow, and operation of source code. In my experience, programs only get near any curve by being tuned, tweaked, hammered, waxed, and in general turned into "code golf". eye and notice things that could be However, the first example is slightly faster as it uses no actual functions and thus requires no stack. Maintainability and Readability Issues. I think the second way is better because it is more easy to read and because the first one duplicates logic of EndsWith method which is bad practice. Typically, maintenance will consume over 70% of the total lifecycle cost of a software product . Before that, some hundreds or thousends Mainframe (each one virtually equipped with their own power plant) used much less energy than today, where 1 CPU minute computes much more than then at a fraction of the cost and energy demand. a requirement). It is not so much that those things cannot coexist. This honors thesis is derived from . 1. There Currently is a local debate as to which code is more readability, We have one programmer who comes from a c background and when that programmer codes it looks like, We have another programmer that doesn't like this methodology and would rather use. It only takes a minute to sign up. But adding code comments is very important for conveying what is being accomplished. Unless and until it does not affect the program performance, no problem you can use either way. easier to read and understand by using It's clear enough for even my manager to understand! In some cases, increased code readability will result in minor performance penalties (let’s be honest; these cases will be rare). Coming at your question from the side of a developer who works on high-performance code, there are several things to consider in design. The most efficient code on the planet will generally lack both maintainability and readability as is probably obvious to most, unless you're the kind that can understand the hand SoA-vectorized, multithreaded SIMD code that Intel writes with inlined assembly, or the most cutting-edge algorithms used in the industry with 40-page mathematical papers published only 2 months ago and 12 libraries … So in my industry at least, I'd like to see more people familiar with computer architecture micro-optimizing more, as Intel has when they stepped into the scene, as opposed to coming up with thousands and thousands of new algorithms and data structures. What does each sample actually say? When you have the choice between two designs that are equal in complexity, choose the one that has the best performance characteristics. ", https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111028#111028. It's up to programmers to let the hardware take advantage of these capabilities more often, by not chewing up every CPU clock cycle available. Exactly. Code Review Stack Exchange is a question and answer site for peer programmer code reviews. If that happens, do that. You might want to define a macro which can be used to simply make everything uniform. Armed with that knowledge I can proceed with evaluating the implementation. I believe that performance and cleanliness are basically uncorrelated. Do not prematurely pessimize. What does that mean? A string's == is not the same between the two languages. https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585740#2585740, https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585753#2585753, https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585748#2585748, Thanks down voter.
