  • Implementing Cluster Continuous Replication, Part 3

    Cluster continuous replication (CCR) uses log shipping and failover to provide a more resilient email system with faster recovery. Once it is installed, a clustered server requires different management routines. These are done either with a GUI tool, The Failover Cluster Management Console, or the Exchange Management Shell. You can use Powershell as well for some tasks. Confused? Not for long, since Brien Posey is once more here to help.

  • Website cookie scanner

    - by user359650
    I'm in charge of a relatively big corporate website (circa 95K pages) and need to perform a cookie audit. I can see cookies issued on a per-page basis with Chrome or Firefox console, but given the amount of pages I need a tool to automate the process. I tried to google for website cookie scanner but my search was unfruitful and found: either online tools which only scan the home page paid services (ex1, ex2) Does any of you know about a tool to scan an entire website and generate a report showing which cookies are being used and which page set them?

  • Creating Ubuntu Live CD with customized Unity launcher

    - by toros
    I would like to create a custom Ubuntu image based on Natty using Ubuntu Customization Kit. I also want to customize the icons appearing on the Unity Launcher. I can change the icons on my desktop system with the following command: gsettings set com.canonical.Unity.Launcher favorites "['firefox.desktop', 'nautilus-home.desktop', 'libreoffice-writer.desktop']" I tried to run this command from the UCK console while creating the Live CD, but it doesn’t seem to work. Do you have any ideas how I could solve this?

  • How to monetize and/or protect framework rights?

    - by Arthur Wulf White
    I made a game engine/framerwork for ActionScript 3 that allows very efficient and flexible level design for Platformers, Tower Defense game, RPG's, RTS and racing games. The algorithms I used are new and are not available in any other level editor I've seen. What are the best ways to benefit myself and others with my new framework? It is written for ActionScript 3 so unless I translate it to C# I'm guessing it will be decompiled and used by others. I want to have some lisence, allowing me to share the framework and still benefit from it. Any advice would be appreciated. This issue has been on my mind a lot this year. I am hoping to find a solution that will bring me some relief.

  • Would a professional, self taught programmer benefit from reading an algorithms book?

    - by user65483
    I'm a 100% self taught, professional programmer (I've worked at a few web startups and made a few independent games). I've read quite a few of the "essential" books (Clean Code, The Pragmatic Programmer, Code Complete, SICP, K&R). I'm considering reading Introduction to Algorithms. I've asked a few colleagues if reading it will improve my programming skills, and I got very mixed answers. A few said yes, a few said no, and a one said "only if you spend a lot of time implementing these algorithms" (I don't). So, I figured I'd ask Stack Exchange. Is it worth the time to read about algorithms if you're a professional programmer who seldom needs to use complex algorithms? For what it's worth, I have a strong mathematical background (have a 2 year degree in Mathematics; took Linear Algebra, Differential Equations, Calc I-III).

  • Dynamic audio score/music

    - by Joel Martinez
    I'm interested in developing a game who's background music changes with the mood and scenario of the game's action. Of course many existing games do this (halo for example), but I was interested in any resources/papers/articles talking about the techniques to develop a system like this. I have some ideas, and I understand that this will be equally challenging to implement at the code level as it will be to come up or acquire music that fits this model. Any links or, answers with ideas in them would he appreciated. Edit: this is the kind of info I'm looking for :) http://halo.bungie.org/misc/gdc.2002.music/

  • Embed IF text parser in another game?

    - by DragonFax
    Are there any existing interactive fiction text parsing engines that I can embed in another game or application? I'm looking to use something as a library. I can pass it the available objects and verbs from my own side. It will parse the sentences from the user and give me back some sort of structure/AST describing what the user asked for. Then my own code can then act upon that request. I don't need something SIRI level. The simple sentences and actions that current IF games support is fine. But I'm not looking to write a whole text/sentence parser myself. This isn't an If game and I can't write it entirely in an interactive-fiction language like inform 7. Unfortunatly, I can't seem to find any examples of anyone using the text parsing capabilities of these engines without writing the entire game in that engine's language.

  • Differences between C# and Javascript for Unity [closed]

    - by vrinek
    Apart from the language differences (class-based vs prototypical, strong vs weak typing), what are the differences between using Javascript and using C# when developing games in Unity3D? Is there a noticable performance difference? Is the javascript code packaged as-is? And if yes, does this help the game's modability? Is it possible to use libraries developed for one language while developing in the other one? Is it possible to mix the two languages in the same Unity project by coding some parts in C# and others in Javascript? The next couple of questions are time-specific so feel free to ignore or remove: If libraries are not cross-functional, which language has better library support from the game development perspective? Which language has better game dev specific resources available (books, websites, forums)?

  • Multiplayer game communication framework for mac/ios

    - by ishaq
    (Cross post from stackoverflow) I am creating a multiplayer 2D game for Mac and iOS devices. I'll be using cocso2d for graphics/game engine, however I am largely blank on what to use for multiplayer communication. Please note that I cannot use central severs e.g. SmartFox, RedDwarf, etc since I want the players to "host" games for others and be able to play it on their LAN, VPN or my own servers. Any pointers? I checked lidgren but it's for .NET only and hence not an option for me. EDIT: just in case it wasn't clear, the messaging has to be real time hence it's probably going to be over UDP

  • JavaScript Class Patterns &ndash; In CoffeeScript

    - by Liam McLennan
    Recently I wrote about JavaScript class patterns, and in particular, my favourite class pattern that uses closure to provide encapsulation. A class to represent a person, with a name and an age, looks like this: var Person = (function() { // private variables go here var name,age; function constructor(n, a) { name = n; age = a; } constructor.prototype = { toString: function() { return name + " is " + age + " years old."; } }; return constructor; })(); var john = new Person("John Galt", 50); console.log(john.toString()); Today I have been experimenting with coding for node.js in CoffeeScript. One of the first things I wanted to do was to try and implement my class pattern in CoffeeScript and then see how it compared to CoffeeScript’s built-in class keyword. The above Person class, implemented in CoffeeScript, looks like this: # JavaScript style class using closure to provide private methods Person = (() -> [name,age] = [{},{}] constructor = (n, a) -> [name,age] = [n,a] null constructor.prototype = toString: () -> "name is #{name} age is #{age} years old" constructor )() I am satisfied with how this came out, but there are a few nasty bits. To declare the two private variables in javascript is as simple as var name,age; but in CoffeeScript I have to assign a value, hence [name,age] = [{},{}]. The other major issue occurred because of CoffeeScript’s implicit function returns. The last statement in any function is returned, so I had to add null to the end of the constructor to get it to work. The great thing about the technique just presented is that it provides encapsulation ie the name and age variables are not visible outside of the Person class. CoffeeScript classes do not provide encapsulation, but they do provide nicer syntax. The Person class using native CoffeeScript classes is: # CoffeeScript style class using the class keyword class CoffeePerson constructor: (@name, @age) -> toString: () -> "name is #{@name} age is #{@age} years old" felix = new CoffeePerson "Felix Hoenikker", 63 console.log felix.toString() So now I have a trade-off: nice syntax against encapsulation. I think I will experiment with both strategies in my project and see which works out better.

  • Where can I find Cinema4D for game development tutorials ?

    - by George Profenza
    Hi, I started to learn Cinema 4D. I've noticed it's really easy to use for motion graphics, but I want to use it for modeling for games/realtime 3d engines. Before I used 3dsmax and it was easy to estimate how a model would look/behave in a 3d engine. The two main things I did was displaying Polygon triangles and displaying the Polygon Count. I've found the Total Polygons tick in HUD settings in Cinema 4D, but I can't find any display mode that will show triangles. Is there there a way to display triangle faces/not quads in Cinema4D ? If so how ? There is a Triangulate function, but I'd rather not Triangulate/Untriangulate all the time, especially since it's converting back and forth between the two doesn't always produce the same result. I imagine I'm asking for old school techniques, but I plan to use these to make low poly models for web(canvas/webGL) and mobile.

  • What Type of Options should be on the Game Settings Menu?

    - by A13X
    I have seen a post about the main menu options here: UI: Main Menu options for mobile games. What options should be listed? What do users want to see? But I want to know what kind of options should/need to be available on the settings screen. I am making a rather simple 2D game for Android, but really I haven't found many aspects that warrant an options button or a check box besides turning the sound and music on/off. I was thinking graphics settings but then again, how many apps really need graphics settings besides immersive 3D ones?

  • Fixing Mobility Radeon HD3650 driver in 12.04 LTS

    - by Kevin
    Okay, I know the subject has been discussed many times, but i dont find any of the instructions working. Most promising guide was here https://launchpad.net/~makson96/+archive/fglrx ive also tried https://help.ubuntu.com/community/BinaryDriverHowto/ATI because since the driver installation was written on other sites as well, this page included a "patch" file, but since im unaware how to patch installations, im out of luck. If i understand correctly, the patch should fix the driver and eliminate constant error messages. My system is 64bit 12.04 LTS and card is Mobility Radeon HD3650. Usual installation of the driver results in weird display resoulution (1100x something, while it should be 1440x900) and even 3d games did not work. Can anyone give me any more pointers? Much appreciated!

  • What should I use Ubuntu for? [closed]

    - by Sean francis Ballais
    I need some of your precious advice co-Ubuntu users. I have been a full Ubuntu user for a few months now and our old 2005 model PC just broke down and so my parents gave me a new PC (notebook). I have installed Windows 7 Ultimate for some reason. Now, my problem is that, since I am a amateur graphic designer, website developer, software developer and other professions a normal teenager won't try and I am using Adobe Creative Suite CS6 Master Collection for my multimedia creation and web development needs, what could I use Ubuntu Linux for? Software development? Website Usability Testing? Other Multimedia stuff? Etc.? Need real help because my mind is getting confused in what should I use Ubuntu for... Any help will be welcomed with appreciation. :D P.S. Don't suggest to me any games because I'm no gamer.

  • Implementing top view physics using box2D

    - by humbleBee
    How can top view physics games be done in box2D? One idea I have is to set the linear velocity of an object manually or to alter the linear and angular damping as my object moves over different surfaces. For example if my object is over a wet surface it'll have less linear damping and if it is over rough surface it'll have more damping. And to see if my object has fallen over an edge I'll try to use an AABB and check if its still inside or manually see if object.x > boundary.x etc. Is there any better way?

  • Game engine design: Multiplayer and listen servers

    - by jarx
    My game engine right now consists of a working singleplayer part. I'm now starting to think about how to do the multiplayer part. I have found out that many games actually don't have a real singleplayer mode, but when playing alone you are actually hosting a local server as well, and almost everything runs as if you were in multiplayer (except that the data packets can be passed over an alternate route for better performance) My engine would need major refactoring to adapt to this model. There would be three possible modes: Dedicated client, Dedicated server and Client-Server (listen mode) * How often is the listen-server model used in the gaming industry? * What are the (dis)advantages of it? * What other options do I have?

  • Subterranean IL: Exception handling 1

    - by Simon Cooper
    Today, I'll be starting a look at the Structured Exception Handling mechanism within the CLR. Exception handling is quite a complicated business, and, as a result, the rules governing exception handling clauses in IL are quite strict; you need to be careful when writing exception clauses in IL. Exception handlers Exception handlers are specified using a .try clause within a method definition. .try <TryStartLabel> to <TryEndLabel> <HandlerType> handler <HandlerStartLabel> to <HandlerEndLabel> As an example, a basic try/catch block would be specified like so: TryBlockStart: // ... leave.s CatchBlockEndTryBlockEnd:CatchBlockStart: // at the start of a catch block, the exception thrown is on the stack callvirt instance string [mscorlib]System.Object::ToString() call void [mscorlib]System.Console::WriteLine(string) leave.s CatchBlockEnd CatchBlockEnd: // method code continues... .try TryBlockStart to TryBlockEnd catch [mscorlib]System.Exception handler CatchBlockStart to CatchBlockEnd There are four different types of handler that can be specified: catch <TypeToken> This is the standard exception catch clause; you specify the object type that you want to catch (for example, [mscorlib]System.ArgumentException). Any object can be thrown as an exception, although Microsoft recommend that only classes derived from System.Exception are thrown as exceptions. filter <FilterLabel> A filter block allows you to provide custom logic to determine if a handler block should be run. This functionality is exposed in VB, but not in C#. finally A finally block executes when the try block exits, regardless of whether an exception was thrown or not. fault This is similar to a finally block, but a fault block executes only if an exception was thrown. This is not exposed in VB or C#. You can specify multiple catch or filter handling blocks in each .try, but fault and finally handlers must have their own .try clause. We'll look into why this is in later posts. Scoped exception handlers The .try syntax is quite tricky to use; it requires multiple labels, and you've got to be careful to keep separate the different exception handling sections. However, starting from .NET 2, IL allows you to use scope blocks to specify exception handlers instead. Using this syntax, the example above can be written like so: .try { // ... leave.s EndSEH}catch [mscorlib]System.Exception { callvirt instance string [mscorlib]System.Object::ToString() call void [mscorlib]System.Console::WriteLine(string) leave.s EndSEH}EndSEH:// method code continues... As you can see, this is much easier to write (and read!) than a stand-alone .try clause. Next time, I'll be looking at some of the restrictions imposed by SEH on control flow, and how the C# compiler generated exception handling clauses.

  • Knowing so much but application is a problem?

    - by Moaz ELdeen
    In my work, my friends always tell me, you know so much about computer science, electronics engineering,..etc. But I have difficulty in applying them and my code is crap. How to solve that problem? Will I be better or programming isn't my career? For example, yes I know OCTree that is used for space partitioning in games and it is used for optimization, did I implement it? No, but I know about it in principle.. Do I know algorithms like Sorting, Searching,..etc? Yes, and I know them pretty well, but didn't implement them.. When I get a task, I struggle in applying the things that I know...

  • Is there a way to install Ubuntu stripped down without desktop applications?

    - by Nick Berardi
    Just to start off, I know of lubuntu but it really doesn't meet what I am looking for. Basically what I am looking for is the standard Desktop Ubuntu install, but with out all the word processing, multimedia, and games installed. I have seen posts out about how to get the desktop environment running on Ubuntu server, but they seem complicated, and never seem to equal the standard Desktop install. So my question is, is there anyway to tell the standard Desktop install not to install all the applications? Or is there a distro available that leaves all the applications out, and just has the standard desktop look and feel? What I really want this for is, is for development purposes to run on a VM to do Mono development.

  • Agile Testing Days 2012 – My First Conference!

    - by Chris George
    I’d like to give you a bit of background first… so please bear with me! In 1996, whilst studying for my final year of my degree, I applied for a job as a C++ Developer at a small software house in Hertfordshire  After bodging up the technical part of the interview I didn’t get the job, but was offered a position as a QA Engineer instead. The role sounded intriguing and the pay was pretty good so in the absence of anything else I took it. Here began my career in the world of software testing! Back then, testing/QA was often an afterthought, something that was bolted on to the development process and very much a second class citizen. Test automation was rare, and tools were basic or non-existent! The internet was just starting to take off, and whilst there might have been testing communities and resources, we were certainly not exposed to any of them. After 8 years I moved to another small company, and again didn’t find myself exposed to any of the changes that were happening in the industry. It wasn’t until I joined Red Gate in 2008 that my view of testing and software development as a whole started to expand. But it took a further 4 years for my view of testing to be totally blown open, and so the story really begins… In May 2012 I was fortunate to land the role of Head of Test Engineering. Soon after, I received an email with details for the “Agile Testi However, in my new role, I decided that it was time to bite the bullet and at least go to one conference. Perhaps I could get some new ideas to supplement and support some of the ideas I already had.ng Days” conference in Potsdam, Germany. I looked over the suggested programme and some of the talks peeked my interest. For numerous reasons I’d shied away from attending conferences in the past, one of the main ones being that I didn’t see much benefit in attending loads of talks when I could just read about stuff like that on the internet. So, on the 18th November 2012, myself and three other Red Gaters boarded a plane at Heathrow bound for Potsdam, Germany to attend Agile Testing Days 2012. Tutorial Day – “Software Testing Reloaded” We chose to do the tutorials on the 19th, I chose the one titled “Software Testing Reloaded – So you wanna actually DO something? We’ve got just the workshop for you. Now with even less powerpoint!”. With such a concise and serious title I just had to see what it was about! I nervously entered the room to be greeted by tables, chairs etc all over the place, not set out and frankly in one hell of a mess! There were a few people in there playing a game with dice. Okaaaay… this is going to be a long day! Actually the dice game was an exercise in deduction and simplification… I found it very interesting and is certainly something I’ll be using at work as a training exercise! (I won’t explain the game here cause I don’t want to let the cat out of the bag…) The tutorial consisted of several games, exploring different aspects of testing. They were all practical yet required a fair amount of thin king. Matt Heusser and Pete Walen were running the tutorial, and presented it in a very relaxed and light-hearted manner. It was really my first experience of working in small teams with testers from very different backgrounds, and it was really enjoyable. Matt & Pete were very approachable and offered advice where required whilst still making you work for the answers! One of the tasks was to devise several strategies for testing some electronic dice. The premise was that a Vegas casino wanted to use the dice to appeal to the twenty-somethings interested in tech, but needed assurance that they were as reliable and random as traditional dice. This was a very interesting and challenging exercise that forced us to challenge various assumptions, determine/clarify requirements but most of all it was frustrating because the dice made a very very irritating beeping noise. Multiple that by at least 12 dice and I was dreaming about them all that night!! Some of the main takeaways that were brilliantly demonstrated through the games were not to make assumptions, challenge requirements, and have fun testing! The tutorial lasted the whole day, but to be honest the day went very quickly! My introduction into the conference experience started very well indeed, and I would talk to both Matt and Pete several times during the 4 days. Days 1,2 & 3 will be coming soon…
