  • How to train yourself to avoid writing “clever” code?

    - by Dan Abramov
    Do you know that feeling when you just need to show off that new trick with Expressions or generalize three different procedures? This does not have to be on Architecture Astronaut scale and in fact may be helpful but I can't help but notice someone else would implement the same class or package in a more clear, straightforward (and sometimes boring) manner. I noticed I often design programs by oversolving the problem, sometimes deliberately and sometimes out of boredom. In either case, I usually honestly believe my solution is crystal clear and elegant, until I see evidence to the contrary but it's usually too late. There is also a part of me that prefers undocumented assumptions to code duplication, and cleverness to simplicity. What can I do to resist the urge to write “cleverish” code and when should the bell ring that I am Doing It Wrong? The problem is getting even more pushing as I'm now working with a team of experienced developers, and sometimes my attempts at writing smart code seem foolish even to myself after time dispels the illusion of elegance.

  • Are there code reviews in opensource projects? If so, what tools are used to do this?

    - by monksy
    I know there is a big push for code reviews in commercial development. However, are code reviews used in open source software or is based on trust? If so, then how are they performed? [Is it a delayed commit, "a pre commit environment", is there a tool that allows for the patch to be sent to another dev]? Are there any projects that use code reviews? From my understanding the linux kernel is mostly based around trust of the commitor. MySQL was based on the main author's approval and the performance impact.

  • Should companies require developers to credit code they didn't write?

    - by sunpech
    In academia, it's considered cheating if a student copies code/work from someone/somewhere else without giving credit, and tries to pass it off as his/her own. Should companies make it a requirement for developers to properly credit all non-trivial code and work that they did not produce themselves? Is it useful to do so, or is it simply overkill? I understand there are various free licenses out there, but if I find stuff I like and actually use, I really feel compelled to give credit via comment in code even if it's not required by the license (or lack thereof one).

  • Being prepared for a code review as a developer?

    - by Karthik Sreenivasan
    I am looking for some ideas here. I read the article How should code reviews be Carried Out and Code Reviews, what are the advantages? which were very informative but I still need more clarity on the question below. My Question is, Being the target developer, can you suggest some best practices a developer can incorporate before his code is going get reviewed. Currently I practice the following methods PPT for a logical flow Detailed comments. Issue: Even though I have implemented the above practices, they do not help on the review. The problem I faced is, when certain logic is referred, I keep searching for the implementation and the flow and too much time is wasted in the process and I get on people’s nerve. I think a lot of developers would be going through what I am going through as well.

  • New code base, what experiences/recommendations do you have?

    - by hlovdal
    I will later this year start on a project (embedded hardware, C, small company) where I believe that most (if not all) code will be new. So what experiences do you have to share as advice to starting a new code base? What have you been missing in projects that you have been working on? What has worked really well? What has not worked? Let's limit this question to be about things that relate directly to the code (e.g "banning the use of gets()": in scope, version control: border line, build system: out of scope).

  • How do you cope with ugly code that you wrote?

    - by Ralph
    So your client asks you to write some code, so you do. He then changes the specs on you, as expected, and you diligently implement his new features like a good little lad. Except... the new features kind of conflict with the old features, so now your code is a mess. You really want to go back and fix it, but he keeps requesting new things and every time you finish cleaning something, it winds up a mess again. What do you do? Stop being an OCD maniac and just accept that your code is going to wind up a mess no matter what you do, and just keep tacking on features to this monstrosity? Save the cleaning for version 2?

  • Good sites for sharing code snippets & pastes that you can share links to?

    - by acidzombie24
    I know there are site tools to check if your webpage is alive, has compression, etc but lets not get into that. What are useful sites to paste code in and to share links to it? The three i know are http://codepad.org/ shows source and runs code online http://www.pastie.org/ share source with syntax highlighting http://jsfiddle.net/ great for JS help or for the occasional test. What else do you know of? One answer per question. I'll let lints and validators slide since you do paste code into them. Mention a weakness if you do know one so others wont be surprised or disappointed.

  • How to examine the speed of your code results?

    - by Goma
    Hi. Whatever was your choice PHP, ASP.NET, Ruby On Rails or even JSP. You know that you can develop a website to give a specific result or to do some tasks in many ways. I mean you can change your code to make it shorter (or for any other reason) but to give the same result. In this case how do you test which code was faster to excute so you choose it to make your website faster? I mean do you have any tools or ideas in how to test the time of execution for your code and compare it with time of execution after you do some edit?

  • Programming *into* a language vs. writing C code in Ruby

    - by bastibe
    Code Complete states that you should aways code into a language as opposed to code in it. By that, they mean Don't limit your programming thinking only to the concepts that are supported automatically by your language. The best programmers think of what they want to do, and then they assess how to accomplish their objectives with the programming tools at their disposal. (chapter 34.4) Doesn't this lead to using one style of programming in every language out there, regardless of the particular strengths and weaknesses of the language at hand? Or, to put the question in a more answerable format: Would you propose that one should try to encode one's problem as neatly as possible with the particulars of one's language, or should you rather search the most elegant solution overall, even if that means that you need to implement possibly awkward constructs that do not exist natively in one's language?

  • Review before or after code commit, which is better?

    - by fifth
    Traditionally we performed code review before commit, I had an argument with my colleague today, who preferred code review after commit. First, here's some background, we got some experienced developers and we also got new hires with almost zero programming practice. we'd like to perform fast and short iterations to release our product. we all team members locate at same site. The advantages of code review before commit I've learned, mentor new hires try to prevent errors, failures, bad designs in early developing cycle learn from others knowledge backup if someone quits But I also got some bad experience, like low efficiency, some changes may be reviewed over days hard to balance speed and quality, especially for newbies some guy felt distrust As to post-review, I just knew little about this, but the most thing I worried about is the risk of losing control, people never review. Any opinions?

  • Code Golf: Shortest Turing-complete interpreter.

    - by ilya n.
    I've just tried to create the smallest possible language interpreter. Would you like to join and try? Rules of the game: You should specify a programming language you're interpreting. If it's a language you invented, it should come with a list of commands in the comments. Your code should start with example program and data assigned to your code and data variables. Your code should end with output of your result. It's preferable that there are debug statements at every intermediate step. Your code should be runnable as written. You can assume that data are 0 and 1s (int, string or boolean, your choice) and output is a single bit. The language should be Turing-complete in the sense that for any algorithm written on a standard model, such as Turing machine, Markov chains, or similar of your choice, it's reasonably obvious (or explained) how to write a program that after being executred by your interpreter performs the algorithm. The length of the code is defined as the length of the code after removal of input part, output part, debug statements and non-necessary whitespaces. Please add the resulting code and its length to the post. You can't use functions that make compiler execute code for you, such as eval(), exec() or similar.

  • What is the way to understand someone else's giant uncommented spaghetti code? [closed]

    - by Anisha Kaul
    Possible Duplicate: I’ve inherited 200K lines of spaghetti code — what now? I have been recently handled a giant multithreaded program with no comments and have been asked to understand what it does, and then to improve it (if possible). Are there some techniques which should be followed when we need to understand someone else's code? OR do we straightaway start from the first function call and go on tracking next function calls?

  • How can I locate empty space next to polygon regions?

    - by Stephen
    Let's say I have the following area in a top-down map: The circle is the player, the black square is an obstacle, and the grey polygons with red borders are walk-able areas that will be used as a navigation mesh for enemies. Obstacles and grey polygons are always convex. The grey regions were defined using an algorithm when the world was generated at runtime. Notice the little white column. I need to figure out where any empty space like this is, if at all, after the algorithm builds the grey regions, so that I can fill the space with another region. Basically what I'm hoping for is an algorithm that can detect empty space next to a polygon.

  • Dynamic obstacles avoidance in navigation mesh system

    - by Variable
    I've built my path finding system with unreal engine, somehow the path finding part works just fine while i can't find a proper way to solve dynamic obstacles avoidance problem. My characters are walking allover the map and collide with each other while they moving. I try to steering them when collision occurs, but this doesn't work well. For example, two characters block on the road while the third one's path is right in the middle of them and he'll get stuck. Can someone tell me the most popular way of doing dynamic avoidance? Thanks a lot.

  • Joomla Hide Menu Item, or: Using Rich Content as part of the navigation

    - by chiccodoro
    In my Joomla based web site, I have a two layer main menu. The page layout contains two sections whereas the left one displays the content and the right one displays some other kind of content which at the same time serves as a menu. For example, if the user clicks on the "Products" - "SomeCategory" 2nd level menu item, the left section displays an image. The right section lists all products of that category. Each product is represented by an image and text. The content is scrollable. This section is implemented by means of a custom module (mod_custom) assigned to the menu. The content is rich text (HTML). Each product is entered manually by adding a picture and a text in the WYSIWYG editor, and by inserting a link for the picture and text. Now the issue: When the user clicks on a product, I want to display the corresponding product description article ("SomeProduct") to the left, accounting for the following requirements: The bread crumb now displays "Products - SomeCategory - SomeProduct" The main menu still displays the 2nd level for "Products", and "SomeCategory" is still marked as selected. (I would love if the right section which lists the product would remain in the exact same scroll state, but that's a completely different story.) If I link the product entry from the right hand side directly to the article "SomeProduct", then the article appears to the left, but the breadcrumb and menu are reset. So I wanted to create a hidden menu item "SomeProduct" beneath "SomeCategory", and to link the product entry to that menu item. This way, if I click on the product entry, the article appears to the left, the breadcrumb behaves correctly, and the menu state is preserved. However, it is not possible to configure the SomeProduct menu item as "hidden", therefore it appears in the main menu. I found some resources that suggest to create another menu, called "hidden", which does not use any modules, and to create the "SomeProduct" menu item in that menu. Unfortunately this did not work for me: If I link that menu item from the product entry, and click on that entry, then the article appears to the left, but the menu is reset, and the breadcrumb displays "SomeProduct" instead of "Products SomeCategory SomeProduct". Lucky me! I found an appropriate stackexchange site where I can pour out my heart to you guys. Sure you can help me :-)
