challenge you to write code that is A comment will increase readability or maintainability. Programmers usually attribute readability, or more often the lack of, to the code itself. My answer... most developers are bad at their jobs, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111032#111032. I think the main criteria should be which of these most clearly says what the developer wants to do. I think the right answer would be the one that is actually correct. 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. The setup to select from 1 table is a lot simpler than to select from and maintain 8,192 shards. It doesn't seem to get easier to maintain than that... but the code is still very hard to read, and almost necessarily so to be so maintainable (so easy to change without problems). They're not readable. When writing code, developers often overlook or disregard the importance of structure and readability. 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. "EndsWith" is less ambiguous. I've learned so much since then. It's usually maintainability that suffers when you seek a lot of the other two. Write your code simple so even a newbie developer can fix it when needed. With that being said it should be noted that a poorly performing software component could perform poorly just because it was foolishly written and unnecessarily complex based on the ignorance of the original author, (making 8 database calls to build a single entity when just one would do, completely unnecessary code that results in a single code path regardless, etc...) These cases are more a matter of improving code quality and performance increases happening as a consequence of the refactor and NOT the intended consequence necessarily. The thing is most uses cases don't need blinding fast code. better, then you have not improved and The second one is more declarative in style but I can't tell you objectively if it is more readable sine readability is very subjective. C. If that happens, do that. And isolate the code in the third point, as much as possible. In that order'. More often than not, certain tasks require a few lines of code. If you know from the get go that your algorithm needs to be highly efficient, then it will be one of the factors you use to develop it. In many cases you have no business to go anywhere near micro-optimization yet. Proper formatting increases readability and hence maintainability, and also give readers the impression that the code was written by professionals. Since the functions generating iterators have a common format, the type specifier can be replaced without obscuring the meaning of code while improving readability and maintainability. 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. But I wonder if this fringe case is enough to merit a guideline. It’s important to have code that’s easy to understand than it is to have code that’s quick to write. inspiration is the association of code readability and software maintainability. In that order." Let us quickly see some of the formatting issues from vertical as well as horizontal perspectives. striving to write better code each 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 worth of code for one incredibly complex data structure. I worked in a legacy codebase before where almost every single user operation had its own unique data structure and algorithm behind it (adding up to hundreds of exotic data structures). https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585986#2585986, You would do this: if (foo.substring(foo.Length-2,2) == "ar"), https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585722#2585722, https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2586010#2586010, https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585739#2585739, https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585872#2585872, https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2586041#2586041. I hear programmers say that some code “is unreadable.” I read articles and books about readability and maintainability. It affects the aspects of quality above, including portability, usability and most importantly maintainability. If you feel that this question can be improved and possibly reopened. And the indexer will fail is the length is 0. readability and maintainability. As for readability, they both say the same thing to me, but I have been programming for a while. I hope that you can pick some things from this article to improve your code… Algorithmic optimizations are a lower-hanging fruit and are nearly always a lot easier to understand than really low-level optimizations. Because when you move to difference hardware, even something as small as a processor with a different cache size, these things may change. They're extremely orthogonal, they allow the code to often be changed and changed without surprises so epic that we have to rethink the design on a drawing board, even to the point of changing our minds about the overall design, without rewriting everything. Coming at your question from the side of a developer who works on high-performance code, there are several things to consider in design. However, overall simplicity, readability and maintainability is still more important. 1. If you are talking about preparing a string for something greater and that does not necessarily need to focus on the mechanics of the ways that strings are built -- or you just want to keep it simple -- go with the second style. The rest of the time is spent working on improving whatever is most important. Typically you have to compromise a bit in one of those three, if not two, like compromising readability for maintainability, or compromising maintainability for efficiency. If you cannot look at code you Thanks to everybody involved! They will probably both throw null reference exceptions. +1 for "Most programs have plenty of room for improvement in all dimensions. Motivation Improves readability and maintainability. Visual Basic. 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. ", https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111025#111025, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111042#111042, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111033#111033, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111027#111027, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111030#111030, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111050#111050, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111066#111066. You might want to define a macro which can be used to simply make everything uniform. And arguably algorithmic optimizations are more difficult to maintain than micro-optimizations. ", https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111028#111028. I was making the point that the code isn't really the same (and I was revising my statement as you down voted. day. I think most programmers get that gut feeling simply because most of the time, performance code is code based on a lot more informations (about the context, hardware knowledge, global architecture) than any other code in applications. If these systems interact with each other, this should happen so that this system can do this... oh wait, what about that system when this event is triggered?" If you used the first one, developers that are debugging your code may say, "What is this dev trying to do?" The point is that you should not go out of your way to make some thing more efficient if you don't know it is the bottle neck. Disclaimer . Iterator type specifiers tend to be long and used frequently, especially in loop constructs. When you have the choice between two designs that are equal in complexity, choose the one that has the best performance characteristics. Most C# developers are very familiar Because experienced programmers have learned that it's true. 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 … I like the rule of thumb: 'get it beautiful, get it fast. This idea that scalability improvements yield more bang for the buck over micro-tuned code (ex: cache-friendly access patterns, multithreading, SIMD, etc.) Code maintainability results from a variety of factors, one of which is readability. EndsWith properly returns false for empty string input whereas the other test will throw an exception trying to index with -1. It should be noted that this does not mean write whatever you want without concern to performance. I forgot the exact quote but someone once said that if Rome was built like software, it would only take a bird landing on a wall to bring it toppling down. It would have been so much easier if the system could revolve around a couple dozen more widely-applicable data structures, and I think that could have been the case if they were micro-optimized much better. Because the cost of global warming (from those extra CPU cycles scaled by hundreds of millions of PCs plus massive data center facilities) and mediocre battery life (on user's mobile devices), as required to run their poorly optimized code, rarely shows up on most programmer's performance or peer reviews. I'd really like to know the community's thoughts on the opinions expressed in the article below. So the first block of code bases its thought process on the concept of an array of characters. thanks though! 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). Do not prematurely pessimize. Readability of source code. And I am talking here about high level languages. There's a rather good experiment done on this referenced in Meyer's Code Complete. Remove unreachable code refactoring. name). What might be obvious to you might not be obvious to someone else, and vice versa. After a certain point, you have to resort to "real" means like better algorithms and hardware. +1: "Get it right, get it beautiful, get it fast. A string's == is not the same between the two languages. of programming called declarative ", 2020 Stack Exchange, Inc. user contributions under cc by-sa. This refactoring applies to: C#. If you cannot look at code you wrote three months ago with a critical eye and notice things that could be better, then you … The code is straightforward but not intuitive (e.g. A good practice to increase the readability of variables is to keep them in the smallest scope. ), https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2585751#2585751, Are you certain #1 is faster?

We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. 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. "Code is written to be read by humans and incidently run by computers" SICP. We can custom-write anything as well! +1 because this ain't C, and I even like C. @Dinah, consider a person who's done Java but looking at some C#. Exactly. If a program is on the curve, any improvement in one dimension necessarily incurs a cost in the other dimension. 1)Access the character at position one less than the length, and check if it equals the character 'r'. But adding code comments is very important for conveying what is being accomplished. With effective micro-optimizations, people could potentially find fewer and fewer reasons to invent new algorithms. Reliability Code that is constant will not cause dumps which mean that it is more reliable in the application and take fewer downtimes to the business. Sacrificing readability can increase performance -- but only so much. Assuming a well designed component however, it will always be less complex than a similarly well designed component tuned for performance (all other things being equal). The question is about maintainability. Sign up to join this community. I think that makes it clear which is the more maintainable answer. These inspections highlight problems that are potentially more subjective, such as short, disemvoweled identifier names. Making your code clean and maintainable. Click here to upload your image The questioner doesn't say how frequently he finds himself in that situation, and the answerers don't seem to claim to be in that situation frequently. Use a profiler and see that 1) what you have now is an issue and 2) what you changed it to was an improvement. It would be nearly impossible to reason about it in a large scale, but for small pieces of code it is quite obvious. I believe that performance and cleanliness are basically uncorrelated. Other Apart from the question if PCs contributed to global warming, even if it were real: It is a fallacy, that more energy efficiency leads to less energy demand. Even more so because the OP stated that the conflict of opinion is with someone who comes from a C background. They force thinking patterns upon us which make us have to solve problems with as few special cases as possible using the minimum amount of knowledge possible and without causing any side effects. 1.2.3 Maintainability Maintainability is the ability of an item to be retained in, or restored to, a specified condition when maintenance is performed by personnel having specified skill levels, using prescribed procedures and resources, at each prescribed level of maintenance and … When I read it I thought this is a straw man to evict the only true answer: "Because they don't use python. Complex designs have many more facets and possible test cases to consider making the goal of 100% unit test coverage even more of a pipe dream. I am going to start using that. I think such views are usually reactions to attempts at premature (micro-)optimization, which is still prevalent, and usually does way more harm than good. If and ONLY if performance is absolutely critical, you get down and dirty. Choosing one of these "styles" for performance is a micro-optimization that will never pay off as soon as a programmer spends an extra few seconds trying to understand what it does. It's an economic negative externality, similar to a form of ignored pollution. The most common theme in the post: make your intent as clear as possible and declarative programming helps you do that. So a good design isolates the complex, performance intensive parts from the rest of the code, which is kept as simple and clean as possible. 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. ... Readability and Code Formatting. The .EndsWith(...) is probably faster to grasp without considering context. Would like to read the blog ... link above is 404! At the same time, compilers are very good at optimizing common cases. If you're writing Java, and you have a collection you will be calling, https://softwareengineering.stackexchange.com/questions/111021/why-do-so-many-developers-believe-performance-readability-and-maintainability/111038#111038. Formatting your code properly is as important as working code. Also, losing performance at the cost of readability can happen only to some extent. For the record, I agree that EndsWith() is more readable and intuitive. After that, you can make your program as much readable as you want without affecting performance. Just compare the readable and the efficient versions of, say, quicksort. Anybody can ask a question ... Readability vs. maintainability: nested functions. though they may not know it by that One of the famous C++ examples is the prevalence of post-increment of counters (or iterators) in loops. -1 for the question. Ask Question Asked today. Welcome to the part 3 of our unit testing series! @patrik, @SLC You are correct it will crash with an empty string. However, it gets more complicated with more than one character in the endswith argument. The coding standards vary from person to person and from team to team in companies. A few lines of seemingly innocuous code here and there could bring it to a halt to the point of making us reconsider the entire design, and high-level languages which aim to be as readable as possible are no exceptions to such human design errors. the why is not evident from the code itself) When the code is not straightforward for deliberate reasons, such as writing it in a more straightforward or self-documenting manner would sacrifice performance. I mention this case because micro-optimization can potentially improve maintainability tremendously in such a case if it means the difference between hundreds of micro-pessimized data structures that can't even be used safely for strict read-only purposes which involve cache misses left and right vs. just dozens of micro-optimized data structures that perform so much more efficiently all around. When you write for high performance, after you fix any algorithmic optilizations, you get into details that requires far more knowledge about the context. What does this PR do? Maintaining the codebase is time-consuming and not many developers like to do it because it lacks creativity. As a rule, if there is a framework method provided to do the job ... use it. In computer programming and software design, code refactoring is the process of restructuring existing computer code—changing the factoring—without changing its external behavior. Personally I think there is another end to the curve where it goes up again on the right hand side (as long as you move far enough to the right (which probably means re-thinking your algorithm)). It is possible that your attempt to improve a common case means that the compiler does not recognize the pattern anymore and thus can not help you make your code fast. I cant access. The danger is a developer who wastes a sprint on a relatively simple feature trying to squeeze a few extra milliseconds out of his component. Two I think can be feasible. These code bases have a serious issue with readability and maintainability. Oops, I forgot something! trying to find an answer along these lines - if not I was going to write it myself. Precisely because highly performing software components are generally orders of magnitude more complex than other software components (all other things being equal). @statenjason: This just shows how unclear that can be, since the example isn't even doing string comparison, it is doing character comparison. And most of them had very skewed performance characteristics, being very narrowly applicable. Google has it's own standards just as Microsoft and Facebook have their own standards. To improve readability and manageability of the code, you can separate widgets from its own widget class, creating a shallow tree of widgets. 03/10/2020; 2 minutes to read; In this article. here it is all the way at the bottom! This was needed because of performance issues. Now as said, I believe readability and maintainability are not harmonious concepts. a requirement). The point is to not worry about little things that might make things better. @statenjason: fair enough. I’ve learned them in all kinds of projects, teams, and organizations. Maintainability: If the code is un-readable it's useless, no matter how fast it is. @AndrewHare is the link to your blog still available? "When one tries to counter such views, it is easy to fall into - or at least look like - the other extreme" I have issues all the time with people thinking I hold the opposite view when I'm merely balancing out the pros with the cons. Edit: By the way, I'm not saying this code cannot be beautiful, and it should be made as beautiful as it can be, but it's still going to be very complex and often convoluted compared to less optimized code. ADDED: Back in ancient times, the cost of the one computer was millions, so optimizing CPU time was very important. In this article, I will The point is not readability should always trump efficiency. In 2006, Emilio and Valerdi [3] highlighted the role of code readability on software development cost. programming. Readability rules, especially if it implies intent. For example, the following function is an implementation of binary search algorithm: There are also some famous pieces of highly optimised code that will bend most peoples brains that support the case that highly optimised code is difficult to read and understand. The second block of code bases the thought process on how you handle a string more abstractly and with less regard to its implementation under the covers. 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 Set standards help programmers and teams establish self-improvement routines and healthy habits to follow. One problem is that finite developer time means that whatever you seek to optimise takes away from spending time on the other issues. You can also provide a link from the web. You should start by supporting your statement that many developers insist that efficiency leads to unmaintainability. The problem is that everyone's code is slow, unreadable, and unmaintainable on the first iteration. Yet, the total energy demand for computing is higher than before. I much prefer the second (EndsWith) version. Unless and until it does not affect the program performance, no problem you can use either way. 1; ... makes it ambiguous from the calling code's standpoint, whether the procedure might re-assign these ByRef values and … And that's partially because they don't map intuitively to human thought. A code block and a function body create a scope for const and let variables. Get it right, get it beautiful, get it fast. I know, it can be a long time in programming :), https://stackoverflow.com/questions/2585704/net-code-readability-and-maintainability/2687525#2687525, .net code readability and maintainability [closed]. How about a comment. The JITer may, but it depends on many things including how much code is behind the method call. It is not so much that those things cannot coexist. I personally highly regard code readability however the react docs say they recommend you use custom hooks to share code between two components nowadays over any other alternative. In my opinion performance should be a consideration when it's an actual problem (or e.g. IMO, the intent of the original author is clearer in the second example. However, If you spend your time tuning every bit of code to be fast, guess what you did not spend your time doing? Add comments and create some functions to improve readability and maintainability. Also, if the "if" statement has one line, DONT BOTHER USING BRACES, USE A SINGLE INDENTION. Code Review Stack Exchange is a question and answer site for peer programmer code reviews. I believe that a good design also takes performance into consideration at the time it is written, and that a good developer with a good design can write an efficient program without adversely affecting readability or maintainability. declarative code. However, the first example is slightly faster as it uses no actual functions and thus requires no stack. While I acknowledge that there are extreme cases, Why do many developers insist an efficient program/design will result in poor readability and/or poor maintainability, and consequently that performance should not be a design consideration?
