  • When to use an Array vs When to use a Vector, when dealing with GameObjects?

    - by user32465
    I understand that from other answers, Arrays and Vectors are the best choices. Many on SE claim that Linked Lists and Maps are bad for video game programming. I understand that for the most part, I can use Arrays. However, I don't really understand exactly when to use Vectors over Arrays. Why even use Vectors? Wouldn't it be best if I simply always used an Array, that way I know how much memory my game needs? Specifically my game would only ever load a single "Map" area of tiles, such as Map[100][100], so I could very easily have an array of GameObjectContainer GameObjects[100][100], which would reserve an entire map's worth of possible gameobjects, correct? So why use a Vector instead? Memory is quite large on modern hardware.

  • PHP, when to use iterators, how to buffer results?

    - by Jon L.
    When is it best to use Iterators in PHP, and how can they be implemented to best avoid loading all objects into memory simultaneously? Do any constructs exist in PHP so that we can queue up results of an operation for use with an Iterator, while again avoiding loading all objects into memory simultaneously? An example would be a curl HTTP request against a REST server In the case of an HTTP request that returns all results at once (a la curl), would we be better off to go with streaming results, and if so, are there any limitations or pitfalls to be aware of? If using streaming, is it better to replace curl with a PHP native stream/socket? My intention is to implement Iterators for a REST client, and separately a document ORM that I'm maintaining, but only if I can do so while gaining benefits from reduced memory usage, increased performance, etc. Thanks in advance for any responses :-)

  • Looking for articles/books on: How do games make money? What models do they use?

    - by cable729
    I'm trying to research the ways in which games make money. I want to know more about the models they use (free/premium, trial/subscription, free-to-play with micro-transactions, etc.). In addition, I want information on which models work for which games, what models are best for which age groups, etc. I've tried my best to find information, and Google hasn't turned anything up at all. I think I'll stop by my University's library and see if there's anything there. This may seem like a broad question, but I'm looking for links and titles of books, not typed-out answers.

  • On-line Based Conferencing For Admin Panel

    - by Tim Marshall
    Working on my admin panels work station section which will allow the admin to use simple office tools such as word editors, calculators and whatnot. Under this section of the admin panel, I would like to add a conferencing feature which will allow any administrator to connect with another administrator 1-2-1 under the 1-2-1 Conferencing section, or to join a meeting under 'live meeting' section. Upon my search for on-line based, I found there are all these, what seem to be great applications out there, however not all of them are on-line based, and come with a price! I would like to a purely on-line based conferencing/meeting/1-2-1 feature which will allow administrators to communicate via text or sound, stream their video, share their screen and sending of files. I know this sounds like a big feature, and I am not asking for someone to answer by programming one for my website! Does anyone know my best solution to progress to having this feature on my website, any tutorials or free to use, free to modify web plugins? Thank you for your help, Best Regards, Tim

  • Verify uniqueness of new content

    - by rogerkk
    I'm working on a review site, where there is a minor issue with almost duplicate reviews across items. Just a few words are changed. It would be very nice to be able to uncover these duplicates before they are approved by a moderator, and I'm hoping someone could chime in on the best strategy to get there. The site is running Ruby on Rails on a Postgres database and using Thinking Sphinx for search (all on Heroku), and so far the best option I see is to be pulling all the reviews out of the db and using a module like amatch to compare the strings. Not very efficient, so in this case I guess I'll have to limit the number/age of reviews to scan for dupes. Anyone got a better idea?

  • Callbacks: when to return value, and when to modify parameter?

    - by MarkN
    When writing a callback, when is best to have the callback return a value, and when is it best to have the callback modify a parameter? Is there a difference? For example, if we wanted to grab a list of dependencies, when would you do this: function GetDependencies(){ return [{"Dep1" : 1.1}, {"Dept2": 1.2}, {"Dep3" : 1.3}]; } And when would you do this? function RegisterDependencies(register){ register.add("Dep1", 1.1); register.add("Dep2", 1.2); register.add("Dep3", 1.3); }

  • Tips for managing internal and external links using WordPress [closed]

    - by keruilin
    So I'm looking for ways to optimize my site for user and search engine purposes. I've read several articles and looked at several different plugins. To say the least, I'm thoroughly confused as what are the best practices for managing internal and external links. Here is a list of some of my questions: Which internal links should be set to "nofollow"? Which external links should be set to "nofollow"? To what degree does actively managing links contribute to your PR? Should you use "nofollow" blindly on all links in comments? If a link to an external site is broken (404 or whatever), should you "nofollow" that link? What about "noindex"? As you can see, lots of questions. I'm hoping that you experienced webmasters can give a newb some best-practice advice.

    - by Goma
    Imagine that you were given a studio or a room in 7-star hotel which is located by the sea, a luxury car and free massage service. All that were given on the condition that you should write your best code every day. You should come with new ideas and try and try again and again.. Will you accept that? Now come back to me please, the question is: what do you do to encourage youself to like programming and to write more of best practices and to come with new ideas? For example, if you were writing code and you get bored, in this case what do you do? Another example is, what do you do when some days are passed and you did not write anything? How do you recover and get back to work with high energy?

  • 12.10 on Elitebook 8560w w/ WUBI

    - by iSeth
    I am trying dual boot Windows 7 and Ubuntu on my Elitebook 8560w via WUBI. Between Microsoft and HP they used up all my primary partitions so I decided WUBI was the best way to go. It all goes smoothly until I reboot to finish the installation, then it hangs at copying files. It always freezes here: debconf (filter): widget found for ubiquity/install/title debconf (filter): -- 0 OK It also says something about "so and so might freeze best to kill it" but I didn't get it written down. Can anybody tell me what that means? EDIT: This is what it says (In Full): ubuntu kernel: [365.130914] [<c1064d607] ? kthread_freezable_should_stop+0x60/0x60 ubuntu kernel: [365.130914] [<c15d04fe7] kernel_thread_helper+0x6/0x10 debconf (filter): <-- progress set 49 debconf (filter): widget found for ubiquity/install/title debconf (filter): -- 0 OK debconf (filter): <-- progress set 50

  • how to "think in templates", i.e. how to know that a problem can be solved using templates and how to adapt to it?

    - by sap
    I decided to improve my knowledge of template meta-programming, i know the syntax and rules and been playing with counteless examples from online resources. i understand how powerfull templates can be and how much compile time optimization they can provide but i still cant "think in templates", that is, i cant seem to know by myself if a certain problem could best be solved with templates (instead of something else) and if it can, how to adapt that problem to templates. so what im asking is, is there some kind of online resource or maybe book that teaches how to identify problems that could best be solved with templates and how to adapt that problem. basically i want to learn to "think in templates". already asked on stackoverflow but once again people just redirected me to resources on how to use templates, when im really asking is how to know when to use template meta-programming and how to adapt that problem to templates. thanks in advance.

  • Colour scheme for editor - guidelines or medical reccomendations

    - by Kevin D
    Is anyone aware of any studies on what colour scheme is best for use in multi-coloured text based computer work? Specifically in terms of reducing eye strain. For instance is a black back ground and light text best? Should it be a dark colour rather than going all the way to black? I've seen the questions on this site about "which is your favourite" that is not what I am after. I also aware that my question may be to specific asking for a colour scheme, if anyone could link me to some guidelines instead that would be appreciated as well. I'm concious of the fact that anyone using a computer is really using it for text based work but with the multitude of colours used to convey information within our modern IDEs I feel this is a good StackExchange site for this question.

  • Comparing the Performance of Visual Studio&apos;s Web Reference to a Custom Class

    As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using <a href="http://www.4guysfromrolla.com/articles/120705-1.aspx">ASP.NET's Membership system</a> is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a <a href="http://www.4guysfromrolla.com/articles/100803-1.aspx">web service</a> generates markup that auto-creates a <i>proxy class</i>, which handles the low-level details of invoking the web service, serializing parameters,

  • SEO: Joomla Category Page Optimization + Canonical Linking

    - by Huberis
    I'm wondering how best to optimize my Joomla site's SEO. I have pages with multiple articles on each page. Either via category-type pages, or via modules. In each case, I'm not wanting users to access the articles separately from the forward facing, menu-linked pages. I understand however that Joomla still generates a url for those articles, and Google can still crawl and display these articles separate from the pages. My question is what is the best way to control this so that my users get directed only to the front-facing pages? By using the canonical element for each article to point to the front-facing page it's on? Or is there a better method? Thanks for your help!

  • Need to set up shared storage for Guest virtual machines that are running on a Xen host

    - by Sajith
    My environment: I am doing these things at home with the purpose of learning about virtualization techniques. My machine have quad core processor that supports Intel-VT and 8GB RAM. XEN is the virtualization platform. In short, all domUs are LVM based. Mainly I have two questions; I need to have shared storage for these VMs. Something like NFS / NAS / iSCSI etc. However, I don't know which one is the best solution. Therefore, can someone tell me which suits best? Please note that, this shared storage need to be accessed by the other physical machines in the network. How to implement the selected solution for question #1? Any tutorials / guidelines / ebooks will be a great help and highly appreciated. Thank you in advance :)

  • Strategies for porting application from Win32 API to GTK+

    - by Vitor Braga
    I have a legacy application written in C, using the raw Win32 API. The general level of abstraction is low and raw dependency on <windows.h> is common. I would like to port this application to GTK+. There are any kind of guidelines or best practices on how to do this? I've previously ported a MFC application to Qt, but the application was very abstracted - it draw it's own set of widgets, for example - and initial porting was very straightforward. I've been thinking at first using Wine to build a native Linux executable and then trying to slowly refactor it into a GTK+ app. Does some one have best practices or previous experiences to share about this?

  • how to deal with parallel programming

    - by nkint
    Hi. I know that parallel programming is a big resource in computer graphics, with moder machines, and mayebe a computing model that will be grow up in the near future (is this trend true?). I want to know what is the best way to deal with it. there is some practical general purpose usefulness in studying processor n-dimensional mesh, or bitonic sort in p-ram machines or it's only theory for domain specific hardware used in real particular signal elaborations of scientific simulations? Is this the best way to acquire the know how for how to become acquainted with cuda or opencl? (i'm interested in computer graphics applications) and why functional programming is so important to understand parallel computing? ps: as someone has advice me i have forked this discussion from http://stackoverflow.com/questions/4908677/how-to-deal-with-parallel-programming
