  • 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. This is a Community Wiki, meaning neither the question nor answers get the reputation points from votes. But vote anyway!

  • 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?

  • Calling a native callback from managed .NET code (when loading the managed code using COM)

    - by evilfred
    Hi, I am really confused by the multitude of misinformation about native / managed interop. I have a C++ exe which is NOT built using CLR stuff (it is not Managed C++ or C++/CLI and never will be). I would like to access some code I have in a C# assembly. I can access the C# assembly using COM. However, when my C# code detects an event I would like it to call back into my C++ code. The C++ function pointer to call back into will be provided at runtime. Note that the C++ function pointer is a function found in the exe's execution environment. I don't want the managed code to try and load up some DLL to call a function (there is no DLL). How do I pass this C++ function pointer to my C# code through .NET and have my C# code successfully call it? Thanks!

  • Debug .Net Framework's source code only shows disassembly in Visual Studio 2010

    - by jdecuyper
    Hi! I'm trying to debug .Net Framework's source code using Visual Studio 2010 Professional. I followed the steps described in Raj Kaimal's post but I must be doing something wrong since the only code I'm getting to see is the disassembly code: As you can see in the image, the Go to Source Code and the Load Symbols options are disabled. Nevertheless, symbols are downloaded from Microsoft's server since I can see them inside the local cache directory. The code I'm debugging goes as follow: var wr = WebRequest.Create("http://www.google.com"); Console.WriteLine("Web request created"); var req = wr.GetRequestStream(); Console.Read(); When I hit F11 to step into the first line of code, a window pops us looking for the "WebRequst.cs" file inside "f:\dd\ndp\fx\src\Net\System\Net\WebRequest.cs" which does not exists on my machine. What am I missing? Thanks a lot for your help.

  • Formatting code in research reports

    - by RoseOfJericho
    I am currently writing a formal research report, and I'll be including JavaScript and PHP code. None of the sections of code will be more than 25 lines (so they're mere snippets). There will be approx. half a dozen snippets, each of which will have a couple of paragraphs explaining what is happening in the code and a discussion on its pros/cons. Is there an accepted way of displaying code in research reports? I'm thinking in terms of font, spacing, whether the code should be displayed inside the document or in an appendix, and related details. I have no contact with the body the report will be submitted to, and they have no published guidelines on how to format code.

  • Refactor/rewrite code or continue?

    - by Dan
    I just completed a complex piece of code. It works to spec, it meets performance requirements etc etc but I feel a bit anxious about it and am considering rewriting and/or refactoring it. Should I do this (spending time that could otherwise be spent on features that users will actually notice)? The reasons I feel anxious about the code are: The class hierarchy is complex and not obvious Some classes don't have a well defined purpose (they do a number of unrelated things) Some classes use others internals (they're declared as friend classes) to bypass the layers of abstraction for performance, but I feel they break encapsulation by doing this Some classes leak implementation details (eg, I changed a map to a hash map earlier and found myself having to modify code in other source files to make the change work) My memory management/pooling system is kinda clunky and less-than transparent They look like excellent reasons to refactor and clean code, aiding future maintenance and extension, but could be quite time consuming. Also, I'll never be perfectly happy with any code I write anyway... So, what does stackoverflow think? Clean code or work on features?

  • Code Review "ToDo" Follow Up Items

    - by Blake Blackwell
    I am trying to institute code reviews at my company, and recently we had our first code review meeting. During the meeting, several positive suggestions were made and I added TODO comments in my code for following up. After reading suggestions on here on best practices for code reviews, I would like to follow up on all the items I corrected at the start of the next meeting. Is there a way to add a similar type of comment to the code such as FOLLOWUP so that I can quickly highlight through those code segments in the next meeting?

  • Unit testing a SQL code generator

    - by Tom H.
    The team I'm on is currently writing code in TSQL to generate TSQL code that will be saved as scripts and later run. We're having a little difficulty in separating our unit tests between testing the code generator parts and testing the actual code that they generate. I've read through another similar question, but I was hoping to get some specific examples of what kind of unit test cases we might have. As an example, let's say that I have a bit of code that simply generates a DROP statement for a view, given the view schema and name. Do I just test that the generated code matches some expected outcome using string comparisons and then in a later integration or system test make sure that the drop actually drops the view if it exists, does nothing if the view doesn't exist, or raises an error if the view is one that we are marking as not allowing a drop? Thanks for any advice!

  • PPV Code Review - Is it good idea?

    - by user93422
    I believe in (solo) code reviews a lot. But I am in a one-developer-shop now. I would like to have my code reviewed, and willing to pay money for it. Question: Is there a place where I can have my code reviewed for money? Note: I understand that most of us are willing to review some one else code for free, but there is a limit to how much code one (e.g. I) is willing to review for free before getting bored. Question: Is it good idea to pay 3d party to do my code-reviews?

  • Embeding EasyVideoPlayer Code into Wordpress Theme - Video not showing

    - by bbacarat
    I'm attempting to place some embed code into a Premium WordPress Theme. NOTE: I'm not great when it comes to php. The embed code is produced by a video player called EasyVideoPlayer. (Basically it allows me to use Amazon S3 and gives me feedback on when people stop watching the video.) This is the embed code I have: _evpInit('ZXh0cmEtbW9uZXktZnJvbS1ob21lLTEubW92'); I've opened the index.php wordpress file and placed this video embed code in between the that represents the area of the website I want it to show up. However the video is not showing. If we place both the theme and video player aside, would you expect the php code to accept what I've done or is this not the way to go about adding this embed code? NOTE:I've contacted both the Wordpress Premium Theme support at Woothemes.com and the video players support for EasyVideoPlayer.com However both tend to stop at the point that another paid product is involved! Grrreat. website is www.extramoneyfromhome.co.uk

  • Putting a dollar value on code quality

    - by Chris Nelson
    As noted in another thread, "In most businesses, code quality is defined in dollars." So my company has an opportunity to acquire a large-ish C code base. Obviously, if the code quality is good, the code base is worth more than if it's poor. That is, if we can readily read, understand, and update the code, it's worth more to us than if it's a spaghetti-coded mess. Without being able to see the code ahead of time, we'd like to set some objective measure as an acceptance criteria like "If the XXX measure is below the price will be discounted YY%." What criteria can we or should we measure and what tool can we use to measure it?

  • Searching for empty methods

    - by Brian McCord
    I am currently working on a security audit/code review of our system. This requires me to check all pages in the system and make sure that the code behind contains two methods that are used to check security. Sometimes the code in these methods get commented out to make testing easier. So, my question is does anyone know an easy way to search code, make sure the methods are present, and to determine which ones have no code or have all the code commented out. It would make my job much easier if I can get a list instead of having to look at every file... I'm sure I could write this myself, but I thought someone may know of something that already exists. Thanks!

  • How to disable 3rd party cookies in Chrome?

    - by David Nordvall
    I have both the "stop websites from storing local data" and the "block all third party cookies without exception" settings enabled in Chrome 12 (I'm not sure what the exact names of these settings are in english as I run Chrome with swedish localization). I do however have two problems. My first problem is that when I'm visiting one of my local news paper's site (and surely other), cookies from www.facebook.com is allowed for some reason. I suspect that the reason is that I have added an exception to the www.facebook.com domain but as the setting "block all third party cookies without exception" implies, that shouldn't matter. My second problem is that if I check what cookies are stored on my computer after browsing for a while, I have tons of cookies that are not on my white list. Primarily from ad services. My expectations from enabling the above mentioned settings was that only cookies that fulfill the two folling requirements would be accepted: the cookies must be from the domain in my address bar the cookies must be from a domain on my whitelist Apparently this isn't the case. The question is, have I completely misunderstood the settings or is this a bug? And, either way, is there a way to accomplish my desired behavior?

  • Remote desktop solution where the desktop sharing party contacts the computer it wants to share with

    - by Kent
    I'm in a situation where I act as a sort of techinical support to my family and less techinically experienced friends. I'm looking for a remote desktop solution where it's possible to setup a "zero-install, double click an icon"-solution where the client computer contacts me so that I may interact with their desktop. The last part is important as the people in need of my help don't know how to configure their router or even the firewall software on their own computer. They are able to click an accept button when asked if a program should be able to make outgoing connections. They have many different kinds of routers, as well as software firewalls, and I rather not deal with the problem of how to connect to them using whatever as well as the actual problem they are having. It must be: Free of charge for non-commercial use. Possible to use it in a mode where the computer wanting to share its desktop should be able to make a connection to my computer. My computer has a DNS name we can use. Compatible with both Windows XP and Windows 7. Independent of a third party server or infrastructure. Explanations of the above: I don't want to spend money on it when I help them for free. If it's free as in freedom, all the better! I guess this boils down to being callable like showdesktopto.exe opscomputer.com where opscomputer.com is my computers DNS name. If that is possible then I can create a shortcut they can use to connect to me when they need help. It's nice if it's possible to specify a password or key file which I can use to authenticate myself, but it's not required. They use the OS which their machine comes installed with. That means Windows XP or 7. I want something which will work in the long run. Using a third party service which might not be available when I need it disqualified such solutions.

  • Network switches for LAN party

    - by guywhoneedsahand
    I am working on setting up the network for a small LAN party (less than 16 people). Most of them do not have wireless cards in their rigs, so I need to set up some way for everyone to a) play LAN games and b) access the internet. The LAN party will probably take place in my basement, where I have enough space. However, the basement is not wired up with the router which is actually on the floor above. I make a cantenna a while back that can boost the wireless performance of my computer significantly. How can I use this to provide internet and LAN to guests? My hope was that I could use a switch like this http://www.newegg.com/Product/Product.aspx?Item=N82E16833181166 for the LAN - but how can I give people access to the internet? Is there such thing as a network extender / 16-port switch? Obviously, the internet performance doesn't need to be super stellar, because the games will be using LAN - so I am looking to provide some usable internet for web browsing, and very high speed LAN for games. Thanks!

  • Working with Legacy code #1 : Draw up a plan.

    - by andrewstopford
    Blackfield applications are a minefield, reaking of smells and awash with technical debt. The codebase is a living hell. Your first plan of attack is a plan. Your boss (be that you, your manager, your client or whoever) needs to understand what you are trying to achieve and in what time. Your team needs to know what the plan of attack will be and where. Start with the greatest pain points, what are the biggest areas of technical debt, what takes the most time to work with\change and where are the areas with the higest number of defects. Work out what classes\functions are mud balls and where all the hard dependencies are. In working out the pain points you will begin to understand structure (or lack of) and where the fundmentals are. If know one in the team knows an area then profile it, understand what lengths the code is going to.  When your done drawing up the list then work out what the common problems are, is the code hard tied to the database, file system or some other hard dependency. Is the code repeating it's self in structure\form over and over etc. From the list work out what are the areas with the biggest number of problems and make those your starting point. Now you have a plan of what needs to change and where then you can work out how it fits into your development plan. Manage your plan, put it into a defect tracker, work item tracker or use notepad or excel etc. Mark off the items on your plan as and when you have attacked them, if you find more items then get them on your plan, keep the movement going and slowly the codebase will become better and better.

  • Code review “on a napkin” — could it be useful?

    - by gaRex
    Preconditions Team uses DVCS IDE supports comments parsing (like TODO and etc.) Tools like CodeCollaborator are expensive for budget Tools like gerrit are too complex for install or not usable Workflow Author publishes somewhere on central repo feature branch Reviewer fetch it and start review In case of some question/issue reviewer create comment with special label, like "BLA". Such label MUST not be in production code -- only on review stage: $somevar = 123; // BLA Why do echo this here? echo $somevar; When reviewer finish post comments -- it just commits with stupid message "comments" and pushes back Author pulls feature branch back and answer comments in similar way or improve code and push it back When "BLA" comments have gone we can think, that review has successfully finished. Author interactively rebases feature branch, stashes it to remove those "comment" commits and now is ready to merge feature to develop or make any action that usualy could be after successful internal review IDE support I know, that custom comment tags are possible in eclipse & netbeans. Sure it also should be in blablaStorm family. So my specific questions are Do you think this methodology is viable? Do you know something similar? What can be improved in it? ps: migrated from http://stackoverflow.com/questions/12692695/code-review-on-a-napkin-could-it-be-useful

  • Is committing/checking in code everyday a good practice?

    - by ArtB
    I've been reading Martin Fowler's note on Continuous Integration and he lists as a must "Everyone Commits To the Mainline Every Day". I do not like to commit code unless the section I'm working on is complete and that in practice I commit my code every three days: one day to investigate/reproduce the task and make some preliminary changes, a second day to complete the changes, and a third day to write the tests and clean it up^ for submission. I would not feel comfortable submitting the code sooner. Now, I pull changes from the repository and integrate them locally usually twice a day, but I do not commit that often unless I can carve out a smaller piece of work. Question: is committing everyday such a good practice that I should change my workflow to accomodate it, or it is not that advisable? Edit: I guess I should have clarified that I meant "commit" in the CVS meaning of it (aka "push") since that is likely what Fowler would have meant in 2006 when he wrote this. ^ The order is more arbitrary and depends on the task, my point was to illustrate the time span and activities, not the exact sequence.
