• As a indie, how to protect your game?

  - by user16829

  As a indie, you might not work in a company. And you may have a great game idea and you feel it gonna be a big success. When you released your game. How do you protect it as your own creation? So that someone also can't steal the title and publish a "sequel" e.g. Your-Game-Name 2,3,4. Or even produce by-products like Angry Birds but without your permission. So how we can prevent these from happening by legal methods. Like copyrights, trademarks? If a professional can fill us those info, it will be great.

• Is it common in companies that non-techs are doing analyzes

  - by Kubi

  It's been 2 months since I started working at an international big consulting company. I like my colleagues personally but it's like a joke since my first day. Analysts (people who has no idea about the tech. background) are planning the workflow and functions. In my case, none of my friends here even wrote even a single line of html. When I say Html, I doubt if they know what I mean. But they are deciding about really key decisions in a web system implementation project. Is this always like this?

• Working with logout dialog box - text error

  - by aaron.kyle

  I am having a problem with the shutdown dialog box for Ubuntu 12.04. If I am logged in as any user and press shutdown, I see the box with the question 'Are you sure..." and its usual options. Shutting down when I am not logged in as a specific user, however, displayed only square boxes. An image of this error can be found here: I believe this error started a few weeks ago when i accidentally changed the group for my root system directory, so it might be a permission thing or an improperly assigned group lingering somewhere. The trouble is that I don't know where the text for this box is stored, and no idea where to begin checking. Can any one point me in the right direction?

• Wireless connection keeps losing connection

  - by Santiago

  I'm having this annoying problem with my Ubuntu 12.04.1, upgraded from 10.04. The thing is that my wireless connection keeps going out of connection every 15-20 minutes, and sometimes I have to reboot my laptop. I've started having this problem about 1 month ago, but back in my 10.04 I had the same problem. If anyone has any idea it would be great. Also any info you need about the laptop, please tell me the commands I need to run to give it to you. Thanks and hope you help me.

• USB Storage Device Automount

  - by matto1990

  Under Ubuntu 10.04 one of the problems which appeared is that USB devices would no longer automatically mount when plugged in. Normally I would get a pop up message asking what application I wanted to open the newly plugged in device with, however now that doesn't happen. This happens regardless of the way the device is formatted (NTFS or FAT32) and all other USB devices (printer, keyboard and mouse) work perfectly. My current solution is the mount them manually using sudo mount dev/... /medai/... however to be honest I'm just getting tired of having to do this. I'm happy to post any extra information you are likely to need. I know there will be lots of places I could look to find out what's going wrong but I have no idea where to start really.

• HELP: I Broke Ubuntu By Uninstalling Compiz

  - by tSquirrel

  I'm still getting used to Linux, having come from Windows. I was receiving an error that "compiz" had crashed a few times so I figured I'd uninstall it. sudo apt-get remove compiz sudo apt-get install compiz I logged out then back in, after that, the GUI was totally gone and I have no idea how to get it back or what I need to do to restore the GUI to what it was before I killed poor Compiz. GUI was pretty much unmodified after a fresh install of 14.04 How can I fix it? I'm not even sure how to get to a terminal or anything. The login screen looks normal, but after logging in, it's a totally bare desktop with my backround and a few icons. No Dash, toolbar, etc. Hot Keys don't seem to work either (Super = Dash doesn't work, etc); although I did accidently open "Disk" UI. Not sure how. Please Help! Right now I'm working off my W7 dualboot.

• Does anyone have a good example/sample of "goto" spaghetti code? [closed]

  - by ArtB

  I've read a lot about how GoTo was considered harmful and removed for other control structures that were more intuitive. Does anyone have a good example / sample of goto spaghetti code? Preferrably, the sample code should be difficult to follow, but realtively easy when rewritten into more conventional control structures. I know I could try to write you some of my own, but I've never really used goto and don't think I could due justice to the headaches its abuse can lead to. I want this for didactic purposes to train junior developers on what to avoid. Mainly, to point to illustrate how OOP is taking the same idea to next logical consequence. EDIT: by good example I mean code that is terrible to read and abuses it, rather than code that uses goto for reasonable optimization

• memory and time intensive php task

  - by Goddard

  Sorry if this question has been asked before, but I couldn't find anything usable. I'm working on a project for a client and currently I have to loop through the users table which is about 3000 records and still growing. I have to do some calculations on a nightly basis which I am going to be using cron/php. The calculations script uses about 3.5mb of memory and takes about 1 second to run. When loading individual users my current php setup handles this fine, but if I try and loop through the user list my php script execution time runs out. I've read after doing some searching that I can make the page reload itself after each user calculation and just keep my previous place in the loop and this sounds like a good idea, but I wanted to hear some opinions from others that have handled similar situations and how you handled these types of tasks. Thanks.

• Pygame - CollideRect - But How Do They Collide?

  - by Chakotay

  I'm having some trouble figuring out how I can handle collisions that are specifically colliding on the top or bottom a rect. How can specify those collisions? Here's a little code snippet to give you an idea of my approach. As it is now it doesn't matter where it collides. # the ball has hit one of the paddles. send it back in another direction. if paddleRect.colliderect(ballRect) or paddle2Rect.colliderect(ballRect): ballHitPaddle.play() if directionOfBall == 'upleft': directionOfBall = 'upright' elif directionOfBall == 'upright': directionOfBall = 'upleft' elif directionOfBall == 'downleft': directionOfBall = 'downright' elif directionOfBall == 'downright': directionOfBall = 'downleft' Thanks in advance. **EDIT** Paddle rect: top ____ | | | | | | Sides | | ---- bottom I need to know if the ball has hit either the top or the bottom.

• Network programming under windows: is WSA functions can be more complete than pSock functions [on hold]

  - by Kane

  I plan to make a set of classic socket functions to simplify their usages. Since i work under windows and linux indifferently i usually make it portable (it's not my first version of this set of functions), but i want to do something different this time and dedicate one version to windows, and one other to linux. With that i wonder for the windows version, if the WSA* functions can have any interest using them instead of the psock ones. I have found nothing about a comparison between them, so if any of you have any idea, suggestion, link or benchmark ?

  - by Nalelvon

  everytime I try to install ubuntu 12.10 on my laptop i get a blackscreen after clicking on "install ubuntu", "try ubuntu without installation" or "ubuntu live" i tried it with nomodeset, nolapic and acpi=off too but nothing works. Sometimes i even get so a loading screen with nothing but "Ubuntu 12.10" and 4 dots in the middle, after that shortly a blackscreen appears with some text on it and then the complete blackscreen appears. As i tried with "no splash" instead of "quiet splash" it shows me something with graphic and determined in it but it was to fast away in a blackscreen to remember. Has someone any idea what I can do to get this working? Sry for my bad english i'm actually from germany. Sincerely Nalelvon

• "A good programmer can be as 10+ times more productive than a mediocre one"

  - by m3th0dman

  I had read an interview with a great programmer (it is not in English) and in it he said that "a great programmer can be as 100 times as good as a mediocre one" giving reason for why good programmers are very well paid and why programming companies give many facilities for their employees. The idea was that there is a very large demand for good programmers, because of the above reason and that's why companies pay very much to bring them. Do you agree with this statement? Do you know any objective facts that could support it? Edit: The question has nothing to do with experience; if you talk about one great programmer with 1 year experience then s/he should be 10 times more productive than a mediocre programmer with 1 year experience. I agree that from certain experience years onwards, things start to dissipate but that's not the purpose of the question.

• Abstract skill/talent system implementation

  - by kiliki

  I've been making small 2D games for about 3 years now (XNA and more recently LWJGL/Slick2D). My latest idea would involve some form of "talent tree" system in a real time game. I've been wracking my brain but can't think of a structure to hold a talent. Something like "Your melee attack is an instant kill if behind the target" I'd like to come up with an abstract object rather than putting random conditionals into other methods. I've solved some relatively complex problems before but I don't even know where to begin with this one. Any help would be appreciated - Java, pseudocode or general concepts are all great.

• What to choose for beginner: PHP/Python/Ruby

  - by Nai

  I'm a beginner teaching myself to code but I would like he insight of the PSE community and helping choose where to start. My main objective is to be able to create a basic website to first test my business idea and from there iterate on it quickly to minimise my learning time. The most important criteria for me is speed. An example of speed would be pre-built components available open source and not having to write one from scratch. From my research, this seems to be a death match between the following languages and frameworks: PHP and CakePHP Python and Django Ruby and Rails Assumptions: I am going to be equally good (or bad) in all 3. It is going to be equally easy to find competent developers in either language. I know this to be false already by lets assume that it is. This question is not meant to karma whore as I've seen how passionate some of these standoff questions have been and I'll be happy to turn it into a community wiki.

• Which language to learn C# or Salesforce.com/apex for C++ programmer [closed]

  - by polapts

  Being a C++ programmer with 7-8 years of experience, I wanted to know the market trends. When I searched a little bit I found more jobs with keyword C# than C++ or Java. I am just wondering if it is a good idea to learn C# or Java from a career perspective. Also, I read somewhere about Salesforce/apex. It was mentioned that this is something in vogue. So my question is which technology I should go for C#/Java/Salesforce(Apex) from career perspective? Thanks

• Best strategy to discover a web service in a local network?

  - by Ucodia

  I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.

• Long term planning and agile?

  - by Ignite

  My team has recently went through the process of laying out a nearly one year plan for our direction of work. We have separated the plan into three phases and each phase will include a couple of launches. I wonder, from an agile point of you, is what we do wrong? I think it's not a bad idea, because we haven't spent too much time on designing anything but the first few steps and it's possible for us to change direction. At the same time it's nice that we don't act with only the near term in sight.

• Code review vs pair programming

  - by mericano1

  I was wondering what is the general idea about code review and pair programming. I do have my own opinion but I'd like to hear from somebody else as well. Here are a few questions, please give me your opinion even on some of the point First of all are you aware of way to measure the effectiveness of this practices? Do you think that if you pair program, code reviews are not necessary or it's still good to have them both? Do you think anybody can do code review or maybe is better done by seniors only? In terms of productivity do you think it suffers from pairing all the times or you will eventually get in back in the long run? Thanks!

• Left and right keys acting crazy on Ubuntu 10.10 Netbook Remix?

  - by Stephanie

  Hi guys, I just installed Ubuntu 10.10 Netbook Remix on my HP Mini 1000. Everything worked fine right up until I tried typing - apparently the left and right arrow keys on my keyboard are uncontrollable. Everything I type ends up looking messed up because the left and right keys keep automatically inserting themselves into everything I type. This also happens when I click on, say, "File" on Firefox. It starts rotating between all the different menu options even though I'm not pressing anything on the keyboard. Does anyone have any idea what's going on? Is this a problem with the keyboard itself?

• What does backup procedures and troubleshooting guidelines mean for a system

  - by Podolski

  I am writing the documentation for a piece of software which I have made but I don't understand what it means in some aspects. It asks me to write about backup procedures but what exactly does this mean? Does this mean like backing up the database on another hosting service or something else entirely? I am dumbfounded by what troubleshooting guidelines are as well. If you have any idea what this could mean feel free to give your insight even if you aren't 100% sure in case it could spark what it means inside of me. Thanks.
