  • What should a game have in order to keep humans playing it?

    - by Adam Davis
    In many entertainment professions there suggestions, loose rules, or general frameworks one follows that appeal to humans in one way or another. For instance, many movies and books follow the monomyth. In video games I find many types of games that attract people in different ways. Some are addicted to facebook gem matching games. Others can't get enough of FPS games. Once in awhile, though, you find a game that seems to transcend stereotypes and appeals almost immediately to everyone that plays it. For instance, Plants Versus Zombies seems to have a very, very large demographic of players. There are other games similar in reach. I'm curious what books, blogs, etc there are that explore these game types and styles, and tries to suss out one or more popular frameworks/styles that satisfy people, while keeping them coming back for more.

  • How are components properly instantiated and used in XNA 4.0?

    - by Christopher Horenstein
    I am creating a simple input component to hold on to actions and key states, and a short history of the last ten or so states. The idea is that everything that is interested in input will ask this component for the latest input, and I am wondering where I should create it. I am also wondering how I should create components that are specific to my game objects - I envision them as variables, but then how do their Update/Draw methods get called? What I'm trying to ask is, what are the best practices for adding components to the proper collections? Right now I've added my input component in the main Game class that XNA creates when everything is first initialized, saying something along the lines of this.Components.Add(new InputComponent(this)), which looks a little odd to me, and I'd still want to hang onto that reference so I can ask it things. An answer to my input component's dilemma is great, but also I'm guessing there is a right way to do this in general in XNA.

  • How essential is it to make a service layer?

    - by BornToCode
    I started building an app in 3 layers (DAL, BL, UI) [it mainly handles CRM, some sales reports and inventory]. A colleague told me that I must move to service layer pattern, that developers came to service pattern from their experience and it is the better approach to design most applications. He said it would be much easier to maintain the application in the future that way. Personally, I get the feeling that it's just making things more complex and I couldn't see much of a benefit from it that would justify that. This app does have an additional small partial ui that uses some (but only few) of the desktop application functions so I did find myself duplicating some code (but not much). Just because of some code duplication I wouldn't convert it to be service oriented, but he said I should use it anyway because in general it's a very good architecture, why programmers are so in love with services?? I tried to google on it but I'm still confused and can't decide what to do.

  • Dual Boot Windows 8 UEFI and Ubuntu 12.10

    - by 0x4a6f4672
    I have got a new Samsung Series 7 laptop with Windows 8 where I tried to install Ubuntu. It is a 64-Bit system which uses UEFI and has "Secure Boot" switched on in the BIOS by default. After I switched if off (and set it to "UEFI and CSM OS") I was able to install Ubuntu (Ubuntu 11.10, which recognized Windows as Windows Vista, although it is Windows 8), by booting from CD with Settings/Change PC Settings/General/Advanced Startup in Windows 8. But after the installation and the restart of the machine somehow ignored Ubuntu and booted only Windows 8. Then I tried to reinstall Ubuntu 12.10. It still only boots Windows 8. Then I tried Boot Repair, which was not really helpful. Any ideas how I can create a dual boot system with Windows 8 and Ubuntu 12.10 ? Here is the link that Boot Repair generated: http://paste.ubuntu.com/1368624/ Is it necessary to create an extra EFI partition with GParted?

  • Which features of user story management should an agile team look for?

    - by Sonja Dimitrijevic
    In my research study, I need to identify the key features of user story management tools that can be used to support agile development. So far, I identified the following general groups of features: User role modeling and personas support, User stories and epics management, Acceptance testing support, High-level release planning, Low-level iteration planning, and Progress tracking. Each group contains some specific features, e.g., support for story points, writing of acceptance tests, etc. Which features of user story management should an agile team look for especially when switching from tangible tools (index cards, pin boards and big visible charts) to a software tool? Are some features more important than the others? Many thanks in advance!

  • Is it important to obfuscate C++ application code?

    - by user827992
    In the Java world, it seems to sometimes be a problem, but, what about C++? Are there different solutions? I was thinking about the fact that someone can replace the C++ library of a specific OS with a different version of the same library, but full of debug symbols to understand what my code does. IS tt a good thing to use standard or popular libraries? This can also happen with some dll library under Windows replaced with the "debug version" of that library. Is it better to prefer static compilation? In commercial applications, I see that for the core of their app they compile everything statically and for the most part the dlls (dynamic libraries in general) are used to offer some third party technologies like anti-piracy solutions (I see this in many games), GUI library (like Qt), OS libraries, etc. Is static compilation the equivalent to obfuscation in the Java world? In better terms, is it the best and most affordable solution to protect your code?

  • How many developers actually have private offices?

    - by Morgan Herlocker
    So I know everyone here is all about private offices, how many developers actually have them. I am sort of half skeptical. I can believe that lead developers have them, but thats normally just one person in your average office. If it would not be to much to ask: Do you work in a totally awesome office or a nasty old cube? (or somewhere in between) What's your relative rank in the office? (junior, programmer II, senior, lead, etc.) are you doing internal software, or are you in a software-centric environment? (the general thought seems to be that internal developers get cubes while others live in "Joel-Spolsky-Programmer-Candyland")

  • eDelivery (Delivery Cloud) Housekeeping - removal of obsolete EPM products

    - by THE
    You may have noticed that Weblogic Server (WLS) 9.2.X and WLS 10.0.X releases have been removed from the Oracle Software Delivery Cloud. The Delivery Team has been asked to remove or update any product pack or product that embeds WLS 10.3.2 or earlier versions. This is consistent with general Oracle practice of removing old product versions from public distribution systems, and encourages customer usage and adoption of newer product releases such as WLS 10.3.3 or newer.  For the convenience of existing supported customers, a media request SR on My Oracle Support can be entered to obtain any removed media.  Information on how to open such an SR can be found on  MOS Doc ID 1071023.1 . OTN will also be reviewed and similar modifications may potentially be done.  The following media packs will be removed from E-Delivery this week, as of the above reason. Hyperion 9.3.1 Hyperion 9.2.1 Hyperion Pre-system 9 EPM 11.1.1.3 EPM 11.1.1.4

  • .NET Compiler Platform (Roslyn) , its relevance to developer community and its performance? [on hold]

    - by jerriclynsjohn
    I'm just starting out with a Code-Quality-plugin development for my organization based on the recently released .NET Compiler Platform APIs (Roslyn APIs). I would like to know what are the most relevant possible ways that it could be used by the developer community apart from the usual IDE experience as answered in other questions. I was wondering the implications of opening up a compiler to general public and never came across anything "breakthrough", that could possibly add up to the value of IDE experiences. Is there any performance bottleneck for its implementation since the compiler itself is managed code?

  • What is the difference between these senior software engineer titles?

    - by stackoverflowuser2010
    I'm currently a senior research software engineer at a large company and am being offered a "senior staff engineer" position somewhere else. I am not sure if the new position's title conveys a sideways move or an advancement. So, all other things being roughly equal (salary, domain of expertise, etc.), what is the external difference between these software engineer titles (in general and regardless of any particular company, if possible): senior engineer senior research engineer senior staff engineer member of technical staff principal engineer Edit: Let me elaborate on "member of technical staff" since it's kind of uncommon. I think it's a high title, commonly associated with research. I know that Oracle, VMWare, and the old Bell Labs have these titles. See: Member of Technical Staff . I know what it means, but I don't know how it stacks up against the other titles, which is why I asked.

  • Is there a class or id that will cause an ad to be blocked by most major adblockers?

    - by Moak
    Is there a general class or ID for a html element that a high majority of popular adblockers will block on a website it has no information for. My intention is to have my advertisement blocked, avoiding automatic blocking is easy enough... I was thinking of maybe lending some ids or classes from big advertisment companies that area already being fought off quite actively. right now my html <ul id=partners> <li class=advertisment><a href=# class=sponsor><img class=banner></a></li> </ul> Will this work or is there a more solid approach?

  • Easy Server-Side Language

    - by Nizar
    Most of programming languages (Server-side languages for web development) needs a learning curve and requires some time to learn. However, I'm sure there is a difference between them. So, for example you can master the 'X' language in less time than the 'Y' language. I'm a beginner in web development, meaning that I just know HTML and CSS and now want to choose the right tool for building dynamic sites. What I'm looking for is a language that is easy to master in less time than other languages. So, is there a language that can suit my needs? If so, please let me know about what should I learn in it? (for example, which frameworks?, libraries?, IDEs?, databases?, etc). In the end, I don't want to regret my choice of the language and want to learn solid basics in it and in programming in general.

  • Only close button shows up in Google Chrome in GNOME Shell

    - by TreefrogInc
    After I installed the GNOME shell in Ubuntu, I decided that I didn't like having the "Close/Minimize/Maximize" buttons on the right, so I switched them over to the left using gconftool-2 --set "/apps/metacity/general/button_layout" --type string "close, minimize, maximize:" After resetting the shell, however, I found that with the GTK+ theme, only the close button shows up. Using system title bar and borders will make all the buttons appear, but I really want to use the theme because the system title bar makes the top bar too thick. Logging out and back in didn't fix it, and I tried reinstalling Chrome, but the problem persists.

  • Rules for Naming

    - by PointsToShare
    © 2011 By: Dov Trietsch. All rights reserved Naming Documents (or is it “Document, Naming”?) Tis but thy name that is my enemy; Thou art thyself, though not a Montague. What's Montague? It is nor hand, nor foot, Nor arm, nor face, nor any other part Belonging to a man. O, be some other name! What's in a name? That which we call a rose By any other name would smell as sweet; So Romeo would, were he not Romeo call'd, Retain that dear perfection which he owes Without that title. Romeo, doff thy name And for that name which is no part of thee Take all myself.  Shakespeare – Romeo and Juliet Act II, Scene 2 We normally only use the bold portion of the famous Shakespearean quote above, but it is really out of context. As the play unfolds, we learn that a name is all too powerful. Indeed it is because of their names that the doomed lovers die. There might be life and death in a name (BTW, when I wrote this monogram, I was in Hatfield, PA. Remember the Hatfields and the McCoys?) This is a bit extreme, but in the field of Knowledge Management (KM) names are of the utmost importance as well. When I write an article about managing SharePoint sites, how should I name it? “Managing a site” or “Site, managing”? Nine times out of ten I’d opt for the latter. Almost everything we do is “Managing” so to make life easier for a person looking for meaningful content, we title our articles starting with the differentiator rather than the common factor. As a rule of thumb, we start the name with the noun rather than the verb. It is not what we do that is the primary key; it is what we do it to. So, answer this – is it a “rule of thumb” or a “thumb rule?” This is tough. A lot of what we do when naming is a judgment call. Both thumb and rule are nouns, albeit concrete and abstract (more about this later), but to most people “thumb rule” is meaningless while “rule of thumb” is an idiom. The difference between knowledge and information is that knowledge is meaningful information placed in context. Thus I elect the “rule of thumb”. It is the more meaningful title. Abstract and Concrete are relative terms. Many nouns (and verbs) that are abstract to a commoner, are concrete to a practitioner of one profession or another and may even have different concrete meanings in different professional jargons. Think about “running”. To an executive it means running a business, to a marathoner its meaning is much more literal. Generally speaking, we store and disseminate knowledge within a practice more than we do it in general. Even dictionaries encyclopedias define terms as they apply to different audiences. The rule of thumb is to put the more concrete first, but within the audience’s jargon. Even the title of this monogram is a question. Do I name it “Naming Documents” or “Documents, Naming”? Well, my own rule of thumb (“Here he goes again!?”) states that the latter is better because it starts with a noun, but this is a document about naming more than it about documents. The rules of naming also apply to graphs and charts, excel spreadsheets, and so on. Thus, I vote for the former.  A better title could have been “Naming Objects” only the word “Object” is a bit too abstract. How about just “Naming” or “Naming, rules of”? You get the drift. One of the ways to resolve all of this is to store the documents in Knowledge-Bases, which may become the subjects of a future punditry. Knowledge bases use keywords to describe their content.  Use a Metadata store for the keywords to at least attempt some common grounds. Here is another general rule (rule of thumb?!!) – put at least the one keyword in the title. Use subtitles. Here is an example: Migrating documents – Screening, cleaning, and organizing our knowledge. The main keyword is “documents”, next is “migrating”, other keywords also appear in the subtitle. They are “screening”, “cleaning”, and “organizing”. Any questions? Send me an amply named document by email: [email protected]

  • Is it a good practice to use branches to maintain different editions of the same software?

    - by Tamás Szelei
    We have a product that has a few different editions. The differences are minor: different strings here and there, very little additional logic in one, very little difference in logic in the other. When the software is being developed, most changes need to be added to each edition; however, there are a few that don't and a few that needs to differ. Is it a valid use of branches if I have release-editionA and release-editionB (..etc) branches? Are there any gotchas? Good practices? Update: Thanks for the insight everyone, lots of good answers here. The general consensus seems to be that it is a bad idea to use branches for this purpose. For anyone wondering, my final solution to the problem is to externalize strings as configuration, and externalize the differing logic as plugins or scripts.

How do you guys go about gathering/structuring/documenting and preparing for a new project in a PHP environment? What things do you ask for up front? PS - I know there are other general questions about this but I want a PHP-flavored one, including tools (even if universal) and approaches. Thanks!! I'm excited but also scared.

  • Does SEO optimisation count on the responsive side of a site?

    - by Rick Donohoe
    I'm looking at making some SEO optimisation fixes, and at this point I'm sorting out the heading structure and keywords - H1's, H2's etc We have a site where there are a number of similar blocks, and one is always visible, and one is hidden depending on the screen size. This is our method of making a single site responsive. Firstly, how does this technique affect the SEO, and in general does the responsive side of a site matter at all to search engines? What I mean by this is if the site has different content depending on screen sizes, then which content would the search spider crawl?

  • What is a "cross-functional team" actually?

    - by Idsa
    The general meaning of "cross-functional team" is a team which combines specialists in different fields that are required to reach the goal. But it looks like in Agile cross-functionality means not only combining different specialists, but making them mix. Henrik Kniberg defines cross-functional team this way: "Cross-functional just means that the team as a whole has all skills needed to build the product, and that each team member is willing to do more than just their own thing." But where is the line drawn? Is it normal to ask developers to become testers for an iteration if it is required?

  • How to reverse file ownership and permission settings

    - by pandisvezia
    I installed LAMP and WordPress on my system a week ago. Since I couldn't create Child Themes in WordPress and work with PHP folders for my other projects collocated in var/www without using Nautilus I wanted to solve the permissions issue. I hoped to bring a solution carrying out the commands on this page for my WordPress folder: http://wiki.apache.org/httpd/FileSystemPermissions. This allowed me to play with any file in the folder like creating and modifying .css files through WP Admin, etc. But after a restart I discovered that I can't change DNS settings of my network connections in the list anymore because it is asking me the root password and even though I enter the password it doesn't let me do the action giving "insufficient privileges" error. Can you help me correct the mistake I possibily made during the configuration and, maybe, configure again the permission and ownership settings for var/www/somefolder as it is adviced to be configured under general circumstances? Thanks in advance!

  • How should I store a Game Database on Android?

    - by Liam
    I'm looking at creating a game for Android and while I have most of the ins and outs worked out, the one thing I'm struggling with is how to store data for the game. Ultimately, the game will be based off of a lot of pre-defined data and statistics so the obvious choice to me would be something like SQLite, but as I'm pretty new to the realm of Android and Game Development, I'm not 100% certain if this is the right route to follow. The data will be general pre-defined data as well as player data (along the lines of careers stats - what place finished, etc). I was wondering if there was a better/best practice solution that wasn't SQLite and that would provide said functionality and if so, could you point me in the right direction?
