• Does Turing-complete implies possibility of malware? [closed]

  - by Mathematician82

  Is it possible to build an operating system that contains some Turing complete compiler (language?) but is unable to run any malware? Or is there any definition for a malware? This question popped on my mind as I was wondering why Windows has more malware than Linux. If Linux contains a C programming language and its compiler, I think it is possible to write a Linux program that works similarly than Windows viruses. But there are less malware for Linux than for Windows although there is a Wine for Linux to simulate Windows programs.

• Installing VMware Worstation/Player 8.0.4 on Ubuntu 12.10 fails to load with Unable to start services

  - by user106986

  I have been attempting to install this application for a few weeks without any success. I have installed and uninstalled the application and pathes with no change. I have even tried to load a VM in Virtualbox and install the application there to a base install of Ubuntu 12.10 and it still did not install. I have downloaded the patch and modified it to reflect the version of VMware Worstation and Player I am installing. I still receive the same error I saw in the first attempt to install the software. Which leads me to think that I am missing something. The error is: Unable to start services. See log file /tmp/vmware-root/modconfig-7674.log for details. I have the output of the log file if that will help. According to the dialogue box Virtual Network Device and VMware Blocking Filesystem fail to either load or execute. Any help would be greatly appreciated.

• What reference point/ tutorial could I use to help me make a "Ball rolling" game in flash?

  - by user1798964

  I am a complete newbie to programming, only took high school Computer science so I kind of know what im doing, I just want to know how I can make a ball rolling game that I want to make, could anyone show me an example of a good "ball rolling game" that has good physics and everything, I have tried to use Box2D for the physics portion of the game, but I found that using that is just code and I can't figure out how to make the graphics and details of the world I want to make in my game, all I would like to do would have a game that has the collision detection and physics of box2d only apply to one ball in it and use the left and right keys to move it. sorry if I am too unclear, if anyone could show a tutorial or something to me on how to make a proper "Ball rolling" game that has good physics that would be appreciated, thank you for taking the time to read this

• What are the Characteristics of a Software "Center of Excellence" (CoE)?

  - by Randy

  Recently a new director of my department came in and expressed his wish that we become a "center of excellence". I expected that since he is my first boss who actually has a programming background that there would be some description of this. However, it was left at that. As I reflected on this over the last few days, I am coming up empty on what a CoE actually means beyond just "being effective" at delivering the product. Here are the main items I am struggling with: Is this just a term that is thrown around by management types? What qualities make a group of software developers and testers excellent? How do you measure excellence in this context?

• La cyber-délinquance se professionnalise de plus en plus d'après le rapport annuel sur les vols de données de Verizon

  Le géant des télécoms Américains Verizon sponsorise depuis maintenant cinq ans son Data Breach Investigation Report annuel. Ce rapport est l'un des plus sérieux disponibles sur la délinquance informatique, se distinguant notamment par une méthodologie transparente (et rigoureuse). Cette année, le DBIR a été réalisé en coopération avec les forces de police de 5 pays : les Etats-Unis, le Royaume-Uni, l'Australie, les Pays-Bas et l'Irlande. Il se base sur 855 intrusions confirmées qui ont compromis 174 millions d'enregistrements dans 36 pays différents pendant l'année 2011.

• Best way to develop a level from Top down image using 3dmax

  - by fire'fly

  I have to create a game level from a top down view of an area. I used a plane converted to an editable poly to do the job. I used edges to create the top view of roads, walkways and parks so that i can extrude/edit them later. My problem is the curves in the road look blocky I tried appying mesh smooth modifier on the final model but that interfered with material mapping. Again i tried it on the plane without the extrusions and still the modifier does not work(The roads loose their shape). I know one way to solve the problem is to add more vertices on the curve and transform their location to create a more natural curve but i have a lot of curves so before doing it manually i need to know if there is a tool that refines the curves. Also i need to know if there is a better or proper way of doing the task.

• Super slow and laggy?

  - by Mystogan

  I'm a native Windows user, running 7 Home Premium atm. In the past I installed Ubuntu 10 on my netbook I believe, but was a bit 'scared' by it. Anyways, I made a partition on my desktop pc, 100gb and installed Ubuntu 12.10 on it. It was pretty slow first thought it had to install updates or something, so I rebooted it. Now after the login it looks like everything freezes, I can move my mouse only ,but that's it! I can see my desktop and launcher, but the task bar doesn't display time and misc system info, only a black bar, I downloaded the android SDK pack and installed vlc media player before I rebooted. My computer info: - 1tb HDD - 8gb ddr3 ram - ATI Radeon 4890 videocard (1gb) - AMD Phenom 2 x4 black 3,2ghz CPU(64 bits) Thanks in advantage!

• Are there any conceptual drawbacks to building a web app with C++ and MySQL?

  - by jnthnclrk

  I've inherited a pretty interesting project where there is a good opportunity to take an existing piece of software and turn it into a SaaS web app. As the project is inherited, the code base/ framework is already defined as C++ and MySQL. The app itself is compiled and run as an EXE on Windows Server. The UI is web based and the app works as a kind of server. From what I do know of modern web apps, this is perhaps an unusual choice. These days, most people seem to opt for a PHP framework or Ruby on Rails. Certainly that is the impression I get from reading blogs on the subject. So, I'm very interested to know if a C++ EXE backed by MySQL is a solid foundation for a web app, or whether we should be looking to build in another way?

• writing 3d game [closed]

  - by user1432980

  I want to write a game as my final year diploma project.(I'm a 4th-year-student now so I've got a year and several months). But I don't know what to choose: either write my own game engine using DirectX9(10)(I don't like OpenGL) or use OGRE + PhysX(Don't like Unity) I'm more interested in writing my own game engine(but I wonder if I'll create engine on the same level as even Unreal 1.0 hah) but on the other side with PhysX I'll have advanced physics in my game and with OGRE I'll have good grahics. For 3d models I want to use Maya. What do you advise me to choose? As for me I've got a little DirectX experience,not bad C++ programming skills(but not expert's) and a little knowledge of Maya. My English isn't perfect either hah...

• Want to learn a new language. Not sure which to pick.

  - by Regravity

  I've been coding in Batch, VBS and AutoIt for AGES, and while its been great and I've made some pretty complex desktop applications in AutoIt, I'd like to advance to something that is more flexible / powerful. I've found that I really love programming desktop applications to solve a wide variety of problems which is what I've been doing with AutoIt. I've done a lot of research on different languages, but I'm torn between a few, namely C++, C# and Python. Can anyone suggest which language I should tackle next? And reasons why I should?

• Huge 2d pixelized world

  - by aspcartman

  I would like to make a game field in a indie-strategic 2d game to be some a-like this popular picture. http://0.static.wix.com/media/6a83ae_cd307e45ffd9c6b145237263ac1a86be.jpg_1024 So every "pixel"(blocks) changes it's color slowly, sometimes a bright color wave happens, etc, but the spaces beetwen this pixels should stay dark (not to count shades, lightning and other 3rd party stuff going on). Units are going to be same "pixelized" and should position them-selfs according those blocks. I have some experience in game-developing, but this task seems not trivial for me. What approaches (shader, tons of sprites or code-render, i don't now) would you recommend me to follow? (I'm thinking of making this game using Unity Engine) Thanks everyone! :)

• How to design an interface, where things need to be called in a specific sequence?

  - by Vorac

  The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?

• Avoid Code Repetition in Condition Statements

  - by Ethosik

  I have been programming for over 15 years now. I consider myself a very good programmer, but I understand (like all of us) there are things that I need to work on. One of these things is code repetition when dealing with conditions. I will give a generic sample: if(condition1) { //perform some logic if(condition2) { //perform some logic if(condition3) { //Perform logic } else { //MethodA(param) } } else { //MethodA(param) } } else { //MethodA() } Now, I cannot make it easy by doing the following: if(condition1 && condition2) { } else { } I cannot do this since I need to perform some logic if condition1 is true and before I test condition2. Is there a way to structure if...else blocks to where if you need to call a method in each else blocks, you are not repeating yourself?

• Default Location of Web Site Content

  - by RichyL

  I am looking to install mediawiki on a production server (after doing a test on a development one). I could not really understand why the default location for the mediawiki files is /var/lib/mediawiki. I would have thought /var/www would've made more sense. I did some research and in http://people.canonical.com/~cjwatson/ubuntu-policy/policy.html/ch-customized-programs.html#s-web-appl it says the following Web Document Root Web Applications should try to avoid storing files in the Web Document Root. Instead they should use the /usr/share/doc/package directory for documents and register the Web Application via the doc-base package. If access to the web document root is unavoidable then use /var/www Can anyone explain why this is please?

• Metro-style / iPhone apps development too demanding for newbie developers? [closed]

  - by linquize

  Both Metro-style and iPhone app require approval and publishing to app store. And they focus most on user interface and the quality of the software. Developers must deal with technical aspects, such as async programming (no UI blocking), no console program (must design a UI that cope with "Standard"), no CPU hungry (pause app if deactivated), need to study the permission matrix (not full access right), and more ... A newbie is not familiar with threading and synchronization. Do you thick they are too demanding for newbie developers? Can you give more examples how demanding it is?

• What methodology to use for planning/developing a Language conversion project?

  - by user 123

  I am trying to help my friend by creating a part of his on-going project. What I'm going to do is create a Java parser to break up the Java code into operators, parameters etc to build XML representation. Next I want to create a code generator to convert the parsed java code to XML conforming to the schema I've created. Finally I want to use an XML style-sheet to transform the XML into another programming language type. Basically I just wanted some advice on which methodology/model I should use for planning and developing this project. Is there some benefit to using Agile etc for instance?

• Web host that handles excess php mailing [closed]

  - by CyberJunkie

  Possible Duplicate: How to find web hosting that meets my requirements? I'm having trouble choosing a host that meets my application's needs. Please kindly inform me what I should look for when choosing a web host. My application is similar to a reminder service that reminds users of events that they scheduled. I'm sending emails to users through a PHP script. I'm not sending one email to multiple recipients. Each recipient receives a different message. I plan to use cron jobs every minute and expect the application to send roughly 200 individual emails in 1 hour (for a small user base that may grow). I don't have hosting experience with this type of application. I plan to start on a shared host and move up in the future to vps or dedicated. Most shared hosts that I looked into allow 50-100 emails per hour with delays between mailings. What do you recommend?

• How to check if my installation of ubuntu is alright?

  - by Likhon

  I recently changed the size of the partition that contained my Ubuntu installation using gparted from a live CD. I also moved it from one place to another. It was my first time and I hit the cancel button during my first try. I completed the task in my second try. But now I see that the size of the "computer" folder has shrinked by 2GB. Now I want to know if the system files are alright as I have backed up my files from the home folder before. How do I do that? Thanks in advance.

• Architects into videogames

  - by Ángel

  I'm an architecture student in my last year. I've always been interested in videogames design. I use 3d Max and Photoshop on a daily basis, and I was thinking about aiming for a career in videogames, starting as a level/environment designer. How should approach it? Is it worthy to spend some time learning UDK or CryEngine? Should I try a smaller but more general software? I know some programming already. Finally, will my skills as an architect be something valuable in the indusrty? Thanks in advance.
