• What do you do when your naming convention clashes with your language?

  - by Jon Purdy

  Okay, this is one of those little things that always bugged me. I typically don't abbreviate identifiers, and the only time I use a short identifier (e.g., i) is for a tight loop. So it irritates me when I'm working in C++ and I have a variable that needs to be named operator or class and I have to work around it or use an abbreviation, because it ends up sticking out. Caveat: this may happen to me disproportionately often because I work a lot in programming language design, where domain objects may mirror concepts in the host language and inadvertently cause clashes. How would you deal with this? Abbreviate? (op) Misspell? (klass) Something else? (operator_)

• Where to draw the line between front end and back end

  - by Twincascos

  I was recently contracted to develop a smarty theme for an automated SOHO phone answering service. The team who had built the backend wouldn't allow me access to any of the back end nor tell me anything about it, their smarty set up, smarty plugins, data base interface api, server set-up, nothing. Nor could I have access to the server nor a beta domain, basically zero co-operation. So I set up a local server with Smarty and built the template based on what I guessed would be their best practice, commented my code like crazy, wrote all the needed javascript, css, and template files. Then I sent them packaged to the backend team and hoped for the best. With half of a project team failing to cooperate or even communicate I am now concerned that they may reply saying that everything is wrong and they may refuse to implement the new front end. I'm curious to know if others encounter this type of situation and what you may have done to protect yourselves.

• Optimal Database design regarding functionality of letting user share posts by other users

  - by codecool

  I want to implement functionality which let user share posts by other users similar to what Facebook and Google+ share button and twitter retweet. There are 2 choices: 1) I create duplicate copy of the post and have a column which keeps track of the original post id and makes clear this is a shared post. 2) I have a separate table shared post where I save the post id which is a foreign key to post id in post table. Talking in terms of programming basically I keep pointer to the original post in a separate table and when need to get post posted by user and also shared ones I do a left join on post and shared post table Post(post_id(PK), post_content, posted_by) SharedPost(post_id(FK to Post.post_id), sharing_user, sharedfrom(in case someone shares from non owners profile)) I am in favour of second choice but wanted to know the advice of experts out there? One thing more posts on my webapp will be more on the lines of facebook size not tweet size.

• Website Stopped Showing From Google Search Results Sunddenly

  - by Aman Virk

  I have a design and development blog http://www.thetutlage.com (1.5 years old), which was doing really well in Google search as I was getting over 70% of my traffic from Google. Now suddenly from last two days it reduced the amount of traffic from 70% to 20% and also when I am trying to search for the exact posts that I can created even after appending my website name to it does not show any results for that. Sample Search Text: JQuery Game Programming Creating A Ping Pong Game Part 1 I have post with exact same title and it does not show it on Google search anywhere. I am totally shocked, I write my own unique content and follow Google guide lines like bible. Also there is no message under my webmasters account stating any problem or error.

• Problem with text deletion in vi editor

  - by user184256

  When I am writing C code on the vi editor, I am not able to use the backspace keys or my arrow keys to delete or navigate through lines. Some unexpected special characters occur on the screen that is on middle of my code and I am not able to delete them also. If I use my delete key, the whole code gets deleted. I have tried both insert mode using 'i' and 'a'. I am able to manage this situation for C programming by using the text editors but when I am creating LeX and yacc programs, I find this awkward. Can you please help me with this?

• Tips/tricks to manage a new team with new code

  - by Fanatic23

  How do you handle yourself in a new team where you are the senior most developer and most others in the team are junior to you by several years. The task ahead of the team is something nobody else including you has accomplished in their career before. Management insists on higher productivity of the whole team, and as senior developer you are responsible. Any tips for coming out trumps in a situation like this? Clearly, the entire team needs time to learn and let's not forget the team's new. However, deadlines are up ahead as well...

• Setting up Developers Conference

  - by Darknight

  In our local city in the UK, there are as far as I am aware no developer conferences. I am confident that our region has many professional developers as well as many graduating students whom who really benefit from a conference. I would like to ask the following questions: What steps or advice would one take if the task was given to set up a local developers conference? What would the costing look like? (excluding building/hosting of website(s)) How would one build interest and promote this? How would I approach, Local Companies & Universities to collaborate with them? I'm not just aiming this question to users who may have experience in setting up such conferences (but are highly welcome). Rather how would you attack this if you was tasked with this?

• Create an Asynchronous JAX-WS Web Service and call it from Oracle BPEL 11g

  - by Bob Webster

  This posting is the result of a simple requirement to take an existing JAX-WS Web service,convert it to be asynchronous and call it from Oracle BPEL 11g It turned out that this is not a trivial task... BPEL has some very specific expectations about the WSDL for an asynchronous process. One approach is to develop the service starting from a WSDL document that meets BPEL's requirements. This is possible but requires considerable WSDL authoring skills. The other approach is to modify the WSDL generated by Web Service Annotations in Java code (Bottom up development) and instruct JAX-WS to use that WSDL instead of dynamically generating one from annotations. This is the approach taken in this article. This posting details how to: Modify a JAX-WS Web Service developed using a "Bottom up " approach to have an asynchronous method and callback. Call the Asynchronous Service from Oracle BPEL 11g. Read the full posting here.

• Strategy/algorithm to divide fair teams based on history

  - by Vegar

  We are a group of people playing floorball together on a regular basis. Every session starts with the daunting task of dividing teams... So what would be better than an application to pick teams automatically? So, given a history of team-combinations and results, and a list of people showing up for this particular session, what would be a good strategy to find the optimal teams? By optimal, I mean teams as equal as possible. Any ideas? Edit: To make it clear, the date that I have to base the picking on, would be something like this: [{ team1: ["playerA", "playerB", "playerC"], team2: ["playerD", "playerE", "playerF"], goals_team1: 10, goals_team2: 8 }, { team1: ["playerD", "playerB", "playerC"], team2: ["playerA", "playerE", "playerG"], goals_team1: 2, goals_team2: 5 }, { team1: ["playerD", "playerB", "playerF"], team2: ["playerA", "playerE", "playerC"], goals_team1: 4, goals_team2: 2 }]

• Design Patterns - do you use them?

  - by seth

  Being an IT student, I was recently given some overview about design patterns by one of our teachers. I understood what they are for but some aspects still keep bugging me. Are they really used by the majority of programmers? Speaking of experience, I've had some troubles while programming, things I could not solve for a while, but google and some hours of research solved my problem. If somewhere in the web I find a way to solve my problem, is this a design pattern? Am I using it? And also, do you (programmers) find yourself looking for patterns (where am I supposed to look btw?) when you start the development? If so, this is certainly a habit that I must start to embrace.

• I'm having trouble learning

  - by Gavin Sapp

  I'm only 13 but i'm genuinely interested in CS and would really like it if I could actually accomplish it. I've read books on C++ and C#, but ALL of them are the same!! They all say "Ok so since you have no prior knowledge in this what so ever, write a snippet that will do this and then make a GUI and then throw it into the Priafdhsu hfad then add the program and then program your own compiler to do some stuff". It's really getting annoying. I've payed near $40 (via Paypal) on ebooks that supposedly taught people to program with no prior knowledge. ALL OF THEM EXPECT ME TO ALREADY KNOW THE LANGUAGE. Is there something that I'm missing or am I suppose to be born with the property of CS? I would very much appreciate it if someone could explain this to me or possibly refer me to a tutorial on Programming Theory that starts from below ground zero as I have know knowledge in CS at all.

• Laptop works fine with ac adapter, hangs after login screen using battery

  - by tavoton

  I did an Ubuntu 10.10 Desktop Edition clean install (amd64 version) on a notebook Medion Akoya E1311. With AC adapter everything works fine, but using battery, it hangs after login screen. I can type login, password too, and I can press login button. But then I can see mouse cursor and lower task bar, not upper, and nothing works. The only thing I can do is login on a terminal with ctrl+alt+F1, this is ok. Nothing seems alive on Gnome except mouse cursor. The only thing I did after Ubuntu fresh install was donwloading driver for RTL8191SE from Realtek web, because WiFi didn't work, now works fine, with ac adapter of course. Hardware is a Notebook Medion Akoya E1311 AMD Sempron 210U 1 GB DDR2 ATI RS690M (Radeon X1200 Series) Western Digital 160GB wireless RTL8191SEvB ethernet RTL8101E/RTL8102E

• How much code should I be responsible for?

  - by Mick

  Through colleagues and exit interviews, I have heard that at my small company I am "responsible" for anywhere from 3-10 times more code than I would be at another job. I'm trying to look for some sort of fuzzy metric that I can use to compare my workload with others in my field. By "code responsibility", I don't mean "I'm the only one who knows area X of the code base" (though sadly, it's often true in a startup environment), but rather am referring to a number like "code_base_size/number_of_developers". Are there any resources I can use to help me more accurately measure my work load than just counting lines of code?

• Have you downloaded the All-In-One Code Framework?

  - by Eric Nelson

  The Microsoft All-In-One Code Framework is a free, centralized code sample library provided by the Microsoft Community team. It aims to provide typical code samples for all Microsoft development technologies. The team listens to developers’ pains in MSDN forums, social media and various developer communities and write code samples based on developers’ frequently asked programming tasks. Additionally, our team offers a free code sample request service. Awesome?! I think so. Have also just added it to 99 technical resources for developers and architects inside ISVs – also worth checking out. Check it out on codeplex

• How to modify VBO data

  - by Romeo

  I am learning LWJGL so i can start working on my game. In order to learn LWJGL I got the idea to implement the map builder so I can get comfortable with graphics programming. Now, for the map creation tool I need to draw new elements or draw the old one's with different coordinates. Let me explain this: My game will be a 2D scroller. The map will be consisting of multiple rectangles ( 2 strip triangles). When I click my left-mouse button i want to start the rectangle and when I release it I want to stop the rectangle bottom-right at that position. As I want to use VBOs I want to know how to modify data inside the VBO based on user input. Should i have a copy of a vertex array and then add the whole array to the VBO at each user input? How is usually implemented the VBO update?

• Technique to Display Multiple Browser Windows Tiled at Same time?

  - by Kendor

  I have a separate monitor that I use for Toodledo (a web-based task managment app), in which I like to display various views (Next Action Status, Waiting Status, Planning Status, and Overdue Due-Date items). I've been playing around with some add-ons on Firefox that allow you to split the browser, but they are cumbersome. I'm now trying Chrome, and opening 4 different browser windows that I've tiled on the screen in quadrants (I use the Compiz grid applet for this). This is not ideal as each browser replicates the URL bar and the tab, and I don't have opening ths windows automated upon restart. Chrome is great in managing screen real estate, but this is not ideal. In Firefox I tried various extension to hide interface elements, but it was very clunky... Am wondering whether anyyone has tried to do similar with TD, and how they achieved what I'm going after? Am wondering whether someone has a good technique for accomplishing what I'm looking for?

• How do I find the closest points(thereby forming a polygon) enclosing a particular point?(see image)

  - by nilspin

  I am working with a game engine, and my task is to add code for simulating fracture of rigid meshes. Right now I'm only working on breaking a cube. I am using Voronoi's algorithm to make a (realistic)fractured shard and I am using the half-plane method to generate a voronoi cell. Now the way I do this is for every seed point, I make planes that are perpendicular bisector planes(the straight black lines in the image) with rest of the seed points and I calculate the intersections of all these planes to give me distinct points(all the orange dots). I've gotten this far. Out of all these calculated intersection points, I only need the ones that are closest and enclosing the seed point(the points encircled in red) and I need to discard all the rest. Information that I have : 1) Plane equations of all planes(defined by normalized normal vectors and their distance from origin) 2) Points of intersection(that I've calculated) Can anybody help me find out how I can find the points encircled in red? Thanks.

• Getting to math applications gradually

  - by den-javamaniac

  I'm currently getting a formal degree related to computation, in particular my current focus is numerical programming, scientific computing and machine learning. I'd love to apply that knowledge in game dev and expand it with statistics, probability theory, and graph theory (probably even linear algebra). The question is: which spheres of gamedev are filled with such math stuff, is it possible to advance in those without being a part of a group of people and how to get to it gradually? P.S.: I've got experience with commercial java dev and am getting my hands on C/C++ at the moment, however, I'm opened to go ahead and try Unity3D and etc.

• Version 5.1.3 of ReSharper released

  - by TATWORTH

  Version 5.1.3 of Resharper has been released by Jetbrains. Download is at http://www.jetbrains.com/resharper/whatsnew/index.html The release notes are at http://blogs.jetbrains.com/dotnet/2011/02/resharper-513-is-released/ Whilst 5.1.3 addresses just a specific issue, if you are programming in C# or VB.NET and if you have never tried Resharper before, you should try it. When I first saw ReSharper in use, within a few minutes I knew that it was worthwhile buying my own copy. Since then I have used it at client site after client site and found it to be a very useful tool.

• problems with studying algorithms

  - by rookie

  hello everyone, I'm currently studying computer science at the Institute, and I have some problems with course which is named Algorithms, I've just begun to study it, but I'm already feeling, that I'm going to fail it, my problem is that while understanding different algorithms on graphs I need to keep in my mind a lot of info, and usually I can't do it, I forget some points of the exercise or can't proceed to final result, I'm very desperate about it cause I like programming very much. Did somebody feel the same while studying in the University? thanks in advance for any help P.S. I began to program only two years ago, may it be the problem?

• What is the best wrapping strategy ?

  - by Riduidel

  Hi, I'm planning to integrate an external tool (ffmpeg in my particular case, but it could be anything, in fact, as lolng as its tasks are long running ones). This tool has a lot of command-line parameters. For now, I've done to simple things with it, already requiring me a good bunch of class writing, to embed all the information it can return to me. I now face the even more complex task of having to send it a bunch of parameters and to handle possible errors. So, what is a best way for that ? Create classes containing all possible options Relying upon a reverse equivalent of commons-cli / CliBuilder / OptionParser Directly write all options from user input Obiwan Kenobi powers (or anything I don't even know about) Please notice I do it in an uncommon language (for the sake of me, don't ask me what it is, as it looks like a desperate and sterile union between CoffeeScript and lua), as a consequence, there can be no framework doing what I want in the language I use.
