  • Simple method for reliably detecting code in text?

    - by Jeff Atwood
    GMail has this feature where it will warn you if you try to send an email that it thinks might have an attachment. Because GMail detected the string see the attached in the email, but no actual attachment, it warns me with an OK / Cancel dialog when I click the Send button. We have a related problem on Stack Overflow. That is, when a user enters a post like this one: my problem is I need to change the database but I don't won't to create a new connection. example: DataSet dsMasterInfo = new DataSet(); Database db = DatabaseFactory.CreateDatabase("ConnectionString"); DbCommand dbCommand = db.GetStoredProcCommand("uspGetMasterName"); This user did not format their code as code! That is, they didn't indent by 4 spaces per Markdown, or use the code button (or the keyboard shortcut ctrl+k) which does that for them. Thus, our system is accreting a lot of edits where people have to go in and manually format code for people that are somehow unable to figure this out. This leads to a lot of bellyaching. We've improved the editor help several times, but short of driving over to the user's house and pressing the correct buttons on their keyboard for them, we're at a loss to see what to do next. That's why we are considering a Google GMail style warning: Did you mean to post code? You wrote stuff that we think looks like code, but you didn't format it as code by indenting 4 spaces, using the toolbar code button or the ctrl+k code formatting command. However, presenting this warning requires us to detect the presence of what we think is unformatted code in a question. What is a simple, semi-reliable way of doing this? Per Markdown, code is always indented by 4 spaces or within backticks, so anything correctly formatted can be discarded from the check immediately. This is only a warning and it will only apply to low-reputation users asking their first questions (or providing their first answers), so some false positives are OK, so long as they are about 5% or less. Questions on Stack Overflow can be in any language, though we can realistically limit our check to, say, the "big ten" languages. Per the tags page that would be C#, Java, PHP, JavaScript, Objective-C, C, C++, Python, Ruby. Use the Stack Overflow creative commons data dump to audit your potential solution (or just pick a few questions in the top 10 tags on Stack Overflow) and see how it does. Pseudocode is fine, but we use c# if you want to be extra friendly. The simpler the better (so long as it works). KISS! If your solution requires us to attempt to compile posts in 10 different compilers, or an army of people to manually train a bayesian inference engine, that's ... not exactly what we had in mind.

  • Javascript source code analysis ( specifically duplication checking )

    - by David
    Partial duplicate of this Notes: I already use JSLint extensively via a tool I wrote that scans in intervals my current project directory for recently updated/created .js files. It's drastically improved productivity for me and I doubt there is anything as good as JSLint for the price (it's free). That said, is there any analysis tool out there that can find repetitive or near-duplicate code blocks, the goal being to make it easier to find opportunities to consolidate large files or small/medium sized projects?

  • Implementation code of native methods

    - by Tapas Bose
    At first I want to let you know that this question is not related with What is native implementation in Java. I got many useful information from that thread. I want to know that are the codes of the native implementations available? I have jdk source code but I can not find the native codes for System.currentTimeMillis or Runtime.getRuntime().availableProcessors() or other native method. Thanks and regards.

  • Code review tool for Vault

    - by Miki Watts
    We're using Vault from SourceGear as our source control repository. Does anyone know if there's a code review tool that can work with Vault, or something that can work with local files ? I've checked the related questions, but I didn't see something that works with local files (of course I may have just missed it).

  • Static code analysis tools for VB6

    - by Maksym Markov
    Right now we are maintaining some old project written in VB6 we are planning to implement continues integration sefver for it. We would like to implement some code analysis as well to track that maintanability at least not getting worse. Basically there is only one requirement - the tool should be command line so we can call it from constinues integration server and it should work with VB6 projects. I will really a;preciate any recommendations regards tools to try. Thank you, Maksym

  • Transiltion from maintenance programing to design

    - by andrew wang
    What to do guys do develop a design for a s/w for a given set of requirements? I like many people joined a Semiconductor MNC and got stuck in maintenance for quite a couple of years. My work was usually changing a lines of code for windows drivers supplied by my company or a couple of small script (style like) C programs for validating h/w. As a result I developed the bad habit of 'programming by coincidence'. I have not developed the ability for designing tools/programs from scratch. I was the only s/w member of the local team and thus some grunt work from the well established other site of the company came to be done by me. Now I have moved to a different company and thus finding developing from scratch very difficult. How do I unlearn my bad habit and develop this ability of designing s/w and then coding it ?

  • PHP beautifiers (libraries for formatting code)

    - by takeshin
    Previously, my intention was to ask: Do you know any open source SQL formatter/beautifier library for PHP projects? But I think, I'd better ask: Which code formatting libraries written in PHP are the best? Let's list them all in one place. My types: for CSS syntax: Css Tidy for PHP: PEAR's PHP_Beautifier for HTML syntax: Tidy

  • Adding images into source code

    - by portoalet
    Is there a way (or an editor) that allows me to link an image/files/http links from within a source file (*.java for instance), sort of like a rich text document ? This way, while reading the code I can quickly look at the appended image (augmenting the comments), instead of opening the browser etc.

  • Suggestions for getting an open source electron beam tracking code going

    - by Boaz
    I work in the field of accelerator physics and synchrotron radiation. High energy electrons circulating in large rings of magnets produce x-rays that are used for a variety of different kinds of science. Running and improving these facilities requires controlling and modelling the electron beam as it circulates in the ring. A code to model this basically requires trackers to follow the electrons through the elements (something called a symplectic integrator), and then the computation of different parameters associated with this motion. The problem with these codes is that every facility has there own. In principle the code is not so complex. And as a modelling project, one might think it has some general interest. Who doesn't want to be able to create a track in space out of magnets and watch the electrons circulate? There is a Matlab based code to do this called Accelerator Toolbox, but the creator of the code is no longer in the field. I put the code in Sourceforge under the name atcollab. The basic resource is in C- it is the set of symplectic integrators. These are available in the atcollab code here. It has been useful to put the code on Sourceforge in order to exchange code, but the community of users is quite small and most are too busy to put that much time into collaboration. So in terms of really improving the code, I don't think it has been so successful. Any piece of this picture could be recreated without that much difficulty, but overall it is a bit complex, and because each lab has their own installation with lots of add-on Matlab code, people find it hard to really work together and share code. Somehow I think we need to involve a wider community in our development, or just use some standard tools. But for that, I suppose it needs to be of some general interest. I think symplectic integrators may have some general interest. And the part about a plug-in architecture to build up the ring ought to fit other patterns. Or the other option is to just accept that this is not a problem of general interest, and work harder within our small community. Suggestions, or anecdotes of analogous experience would be appreciated.

  • How to design a character animation system?

    - by Andrea Benedetti
    I'm searching for suggestions and resources on the possible ways to design a character animation system. I mean a system built on top of the graphics engine (as graphics engine I use Ogre3D, that provide an animation layer), and in strict contact with the logic of the game. It's for a sports title, so the question is not easy. Edit: What I'm searching for are suggestions and resources about the action state mechines (or animation state machines), that is build on top of the animation pipeline already provided by the graphics engine. So, a state-driver animation interface for use by virtually all higher-level game code.

  • How prevent useless content load on the page in Responsive Design

    - by Ícaro Leandro
    In Responsive Design, we hide elements in the page with @media queries and display: hide in the CSS. Ok, But in my system: Browsers that have less than width: 800px, the layout must hide some content, not only hide, but avoid them load fully. I mean, in access with desktop with more than 800px of screen, the page load fully; In mobile devices, or even in desktop with less than 800px, not load some content. I want to make the page load faster in this browsers. The system are maked in PHP and have some Javascript. Thanks...

  • SQLPASS DB Design Precon Preview

    - by drsql
    It is just a few months left before SQLPASS and I am pushing to get my precon prepped for you. While it will be the second time I produce this on the year, I listened to the feedback and positive comments I have heard from potential attendees, so I am making a couple of big changes to fit what people really liked. Lots more design time. We will do more designs in some form, as a group, teams, and individually, depending on the room and people in attendance. (Figure on a lot of databases centered...(read more)

  • How to design a leaderboard?

    - by PeterK
    This sounds like an easy thing but when i considering the following Many players Some have played many games and some just started Different type of statistics ...on what information should the actual ranking be based on. I am planning to display the board in a UITableView so there is limited space available per player. However, I am not bound to the UITableView if there is a better solution. This is a quiz game and the information i am currently capturing per player is: #games played totally #games played per game type (current version have only one game type) #questions answered #correct answers Maybe i should include additional information. I have been thinking about having a leaderboard property page where the player can decide on what basis the leaderboard should display information but would like to avoid the complexity in that. However, if that is needed i will do it. Anyone that can give me some advice on how to design the presentation of this would be highly appreciated?

  • Java code translation of Python array-splitting code

    - by techventure
    Can someone please give the Java equivalent of the below python (which slices a given array into given parts) which was originally written by ChristopheD here: def split_list(alist, wanted_parts=1): length = len(alist) return [ alist[i*length // wanted_parts: (i+1)*length // wanted_parts] for i in range(wanted_parts) ] I don't know any python but can really use the above code in my Java app. Thanks

  • Started wrong with a project. Should I start over?

    - by solidsnake
    I'm a beginner web developer (one year of experience). A couple of weeks after graduating, I got offered a job to build a web application for a company whose owner is not much of a tech guy. He recruited me to avoid theft of his idea, the high cost of development charged by a service company, and to have someone young he can trust onboard to maintain the project for the long run (I came to these conclusions by myself long after being hired). Cocky as I was back then, with a diploma in computer science, I accepted the offer thinking I can build anything. I was calling the shots. After some research I settled on PHP, and started with plain PHP, no objects, just ugly procedural code. Two months later, everything was getting messy, and it was hard to make any progress. The web application is huge. So I decided to check out an MVC framework that would make my life easier. That's where I stumbled upon the cool kid in the PHP community: Laravel. I loved it, it was easy to learn, and I started coding right away. My code looked cleaner, more organized. It looked very good. But again the web application was huge. The company was pressuring me to deliver the first version, which they wanted to deploy, obviously, and start seeking customers. Because Laravel was fun to work with, it made me remember why I chose this industry in the first place - something I forgot while stuck in the shitty education system. So I started working on small projects at night, reading about methodologies and best practice. I revisited OOP, moved on to object-oriented design and analysis, and read Uncle Bob's book Clean Code. This helped me realize that I really knew nothing. I did not know how to build software THE RIGHT WAY. But at this point it was too late, and now I'm almost done. My code is not clean at all, just spaghetti code, a real pain to fix a bug, all the logic is in the controllers, and there is little object oriented design. I'm having this persistent thought that I have to rewrite the whole project. However, I can't do it... They keep asking when is it going to be all done. I can not imagine this code deployed on a server. Plus I still know nothing about code efficiency and the web application's performance. On one hand, the company is waiting for the product and can not wait anymore. On the other hand I can't see myself going any further with the actual code. I could finish up, wrap it up and deploy, but god only knows what might happen when people start using it. What do you think I should do?
