As a simple example, a method named isValid(x) should, as a side effect, convert x to binary and store the result in a database. Use acronyms to keep the code terse. For example code written to the above standard has the following properties: A single assignment statement carries 14 pieces of type and name information. A single function call that passes three parameters and assigns a result carries 29 pieces of type and name information. In the interests of creating employment opportunities in the Java programming field, I am passing on these tips from the masters on how to write code that is so difficult to maintain that the people who come after you will take years to make even the simplest changes. How to Write Unmaintainable Code. For example, C offers a goto command which can be used to jump around code in a very confusing manner. Create classes, methods, and files that have nothing to do with the overall function of your code. Appendix B: Writing Clear Code. Use an editor designed for writing code. For example, if you used our Java installer, IntelliJ will automatically indent and reformat your code when you save it. Here's one guide to designing unmaintainable code and here's another. For example code written to the above standard has the following properties: a single assignment statement carries 14 pieces of type and name violate the Hungarianesque concept that function parameters and other high visibility. How To Write Unmaintainable Code. How To Write Unmaintainable Code. In the interests of creating employment opportunities in the programming field, I am passing on these tips from the masters If, for example, you were writing an airline reservation system. Hello, Can anyone site with an example how to fix this problem. Padma That item refers to: The maintainability index is calculated by using the following metrics: lines of code, program volume, and cyclomatic complexity. Program volume is a measure of the difficulty of understanding of a type or method that is based on the number of. Slicing is allowed by compiler and can be viewed as a special case of dangerous implicit cast. Even if it is done intentionally and doesnt lead to immediate issues, it is still highly discouraged since it makes code rather unmaintainable by forcing additional requirements on related data types. Tutorials for Code Obfuscation in C [closed How to write unmaintainable code. you'll often see plain old macro definitions in obfuscated code entries. For example, redefining a keyword can make reading a. Creating code that is potentially difficult to maintain; And those if statements get pretty messy and unmaintainable especially as new requirements cause nested if statements. There is a better way the strategy pattern. How To Write Unmaintainable Code example, assign a value to a variable at the top of a very long method, and then somewhere in the middle, change the meaning of the variable in a subtle way, such as converting it from a 0based coordinate to a 1based coordinate. rprogramming is a reddit for discussion and news about computer programming. Please keep submissions on topic and of high quality. Just because it has a computer in it doesn't make it programming. If there is no code in your link, it probably doesn't belong here. For example code written to the above standard has the following properties: a single assignment statement carries 14 pieces of type and name information. a single function call that passes three parameters and assigns a result carries 29 pieces of type and name information. How To Write Unmaintainable Code Yet the total amount of code they write dwarfs the code in the compilers. An example of the result of this sort of elitist thinking is the JDBC interface. It makes life easy for the JDBC implementor, but a nightmare for the maintenance programmer. If, for example, you were writing an airline reservation system, make sure there are at least 25 places in the code that need to be modified if you were to add another airline. Never document How To Write Unmaintainable Code (part 2) Yet the total amount of code they write dwarfs the code in the compilers. An example of the result of this sort of elitist thinking is the JDBC interface. It makes life easy for the JDBC implementor, but a nightmare for the maintenance programmer. How to convert C Code to C [closed Ask Question. few template classes and lots of C stuff. Now I need to convert the source to plain C code. But yes, C has effectively lost any advantage over C years ago. Microsoft doesn't even bother with C anymore. Usually they are an unreadable, unmaintainable mess of magic numbers. Furthermore, since it would seem that this specific part is intended solely for missioncritical applications, you would think that the minimum requirement on the examples would be MISRAC compliant code. GoTo (goto, GOTO, GO TO or other case combinations, depending on the programming language) is a statement found in many computer programming languages. It performs a oneway transfer of control to another line of code; in contrast a function call normally returns control. The jumpedto locations are usually identified using labels, though some languages use line numbers. For example, he states that C leads to bad programming practices because of all the high level stuff (such as abstraction, data hiding, etc), while C leads to good programming unmaintainable code Introduction This is my most popular essay. It is amazing how many people dont realise it is tongue in cheek If builders built buildings the way programmers write programs, then the first woodpecker that came along would destroy civilization. The cardinal rule of writing unmaintainable code is to specify each fact in as many places as possible and in as many ways as possible. Roedy ( age: 70) The key to writing maintainable code is to specify each fact about the application in only one place. I have several ways of categorizing code. Production quality, test, demo, and utilities. When I am talking about utilities, I am talking about little programs that I use to do all sorts of small tasks. There I rarely worry about maintainability, and today there was a gem here. How To Write Unmaintainable Code How to write code and not get fired. (or even if you get fired, how to come back and make money, by charging more! ) A good example is a comment select the values before a SELECT statement. Another effective trick is to put a comment temporary procedure, used for debugging before some of the most important procedures. This article describes how to write unmaintainable code and have an excellent paid job for the rest of your life. The key skill to unmaintainable code is the obfuscation of the code besides poor design, no test cases and overly complex algorithms. Share on Facebook, opens a new window; Share on Twitter, opens a new window; Share on LinkedIn; Share by email, opens mail client How To Write Unmaintainable Code. Roedy Green Happily, languages like Java go out of their way to make writing this sort of unmaintainable code easy. For example, it is almost impossible to change the type of a widely used variable because all the casts and conversion functions will no longer work, and the types of the associated temporary. Operator overloading (less commonly known as adhoc polymorphism) Usage of the operator is an example of this problem. Clearly by overloading these operators you can create some very unmaintainable code so overload these operators only with great care. HOW TO WRITE INSECURE CODE Introduction. In the interest of ensuring that there will be a future for hackers, criminals, and others who want to destroy the digital future, this paper captures tips from the masters on how to create insecure code. Thus, the code is functionally unmaintainable once the guru leaves and, again thus, it represents job security for the guru and a business risk for their employer should they, for example, drop dead one day. the art of with examples in C# FOREWORDS BY Michael Feathers Robert C. Martin SECOND EDITION ROY OSHEROVE PART 3T HE TEST CODE awkward, slow, or unmaintainable. ) On a more upbeat note, you may have had a great first experience with unit tests, and youre reading. TechCrunch Urges Developers: Replace C Code With Rust (techcrunch. com) from that anecdote, are we to conclude that C code is unmaintainable, your code is unmaintainable, or both? All in all, your story is a great example of why C is bad. It took a long time to build something that worked correctly, and once completed the code is brittle and. To write unmaintainable code is a very unworthwhile thing to do, because you will be essentially married to the code until you find somebody to which you can explain it. Personally once I write some code I want it to be maintainable enough so other people can contibute for I can move on with other things. But the most important guideline is to watch for warning signs in your own code so called code smells. For example, if you have Open(), you should probably have Close(). And if you want examples of the stinkiest code imaginable, How to Write Unmaintainable Code is a good place to start. Much of the skill in writing unmaintainable code is the art of camouflage, hiding things, or making things appear to be what they are not. Many depend on the fact the compiler is more capable at making fine distinctions than either the human eye or the text editor. Share code with VS implementation of Code Metrics currently we have a clone of the code that computes the metrics. Once we start inserting packages from this repo to VS repo, we can delete the clone and reference that package (which will need to happen. Writing BugFree C Code A Programming Style That Automatically Detects Bugs in C Code not the old existing code. This is an extreme example, but it demonstrates that everyone involved with a project must fully understand new programming methodologies instituted in the middle of a programming project. 7 Unmaintainable Code We all have. For example, one paragraph might be: (this is a real example) When you write the code, do not document the functions. After all, that's what the design document is for! The cardinal rule of writing unmaintainable code is to specify each fact in as many places as possible and in as many ways as possible. Writing unmaintainable code is a special skill that, strangely enough, seem to come quite naturally to certain developers. But for the rest of you, here are some. C# BAD PRACTICES: Learn how to make a good code by bad example. It is completely unreadable, unmaintainable, unextendable and it is using many bad practices and antipatterns. Learn how to make a good code by bad example Part 2 which is a continuation of Part 1 Thank you for your comment, Radoslaw: Focus on different stuff first. How to write unmaintainable PHP code [2009 September 18th, 2015. Tagged: into the database access layer for example. In general, strive for a healthy mix of PHP, HTML, CSS and JavaScript, possibly on the same line of code. Write PHP that creates JavaScript that creates HTML with inline styles. If asked, call this pattern encapsulation. variant, morph the variable, for example, assign a value to a variable at the top of a very long method, and then somewhere in the middle, change the meaning of the variable in a subtle way, such as converting it from a 0based coordinate to a 1based coordinate. Adding methods() to structures in C unmaintainable code, as well as the deadly diamond of death, where both parent classes share one or more Example For reference, C treats structures as structures for backward compatibility, but with the default access specifier as The best example we ever saw of this was from a mathematician writing code in Matlab. He initialized dozens of variables, several arrays, performed various operations to get everything situated properly in. An anonymous reader writes Make sure you're irreplaceable ' In the interests of creating employment opportunities in the Java programming field, I am passing on these tips from the masters on how to write code that is so difficult to maintain, that the people who come after you will take years to. If you do this well, the users will be hopelessly confused between reserved keywords and arbitrary names in your example, but you can look innocent, claiming you did it to help them associate the appropriate purpose with each variable. How To Write Unmaintainable Code Introduction For example code written to the above standard has the following properties: a single assignment statement carries 14 pieces of type and name information. a single function call that passes three parameters and assigns a result carries 29 pieces of type and name information. For example code written to the above standard has the following properties: a single assignment statement carries 14 pieces of type and name information. a single function call that passes three parameters and assigns a result carries 29 pieces of type and name information..
