  • IOS OpenGl transparency performance issue

    - by user346443
    I have built a game in Unity that uses OpenGL ES 1.1 for IOS. I have a nice constant frame rate of 30 until i place a semi transparent texture over the top on my entire scene. I expect the drop in frames is due to the blending overhead with sorting the frame buffer. On 4s and 3gs the frames stay at 30 but on the iPhone 4 the frame rate drops to 15-20. Probably due to the extra pixels in the retina compared to the 3gs and smaller cpu/gpu compared to the 4s. I would like to know if there is anything i can do to try and increase the frame rate when a transparent texture is rendered on top of the entire scene. Please not the the transparent texture overlay is a core part of the game and i can't disable anything else in the scene to speed things up. If its guaranteed to make a difference I guess I can switch to OpenGl ES 2.0 and write the shaders but i would prefer not to as i need to target older devices. I should add that the depth buffer is disabled and I'm blending using SrcAlpha One. Any advice would be highly appreciated. Cheers

  • SQLAuthority News – SQL Server Interview Questions And Answers Book Summary

    - by pinaldave
    Today we are using computers for various activities, motor vehicles for traveling to places, and mobile phones for conversation. How many of us can claim the invention of micro-processor, a basic wheel, or the telegraph? Similarly, this book was not written overnight. The journey of this book goes many years back with many individuals to be thanked for. To begin with, we want to thank all those interviewers who reject interviewees by saying they need to know ‘the key things’ regardless of having high grades in class. The whole concept of interview questions and answers revolves around knowing those ‘key things’. The core concept of this book will continue to evolve over time. I am sure many of you will come along with us on this journey and submit your suggestions to us to make this book a key reference for anybody who wants to start with SQL Server. Today we want to acknowledge the fact that you will help us keep this book alive forever with the latest updates. We want to thank everyone who participates in this journey with us. Though each of these chapters are geared towards convenience we highly recommend reading each of the sections irrespective of the roles you might be doing since each of the sections have some interesting trivia about working with SQL Server. In the industry the role of accidental DBA’s (especially with SQL Server) is very common. Hence if you have performed the role of DBA for a short stint and want to brush-up your fundamentals then the upcoming sections will be a great review.

  • LLVM-3.1 libLLVMSupport.a undefined reference to `dladdr'

    - by user91387
    I'm trying to compile using the llvm-3.1 package. I'm running 12.04 x64 (3.2.0-26 kernel) && 12.10 (3.5.0-4) x64 backported llvm-3.1 from quantal, then debian experimental.

  • how do I write a functional specification quickly and efficiently

    - by giddy
    So I just read some fabulous articles by Joel on specs here. (Was written in 2000!!) I read all 4 parts, but Im looking for some methodical approaches to writing my specs. Im the only lonely dev, working on this fairly complicated app (or family of apps) for a very well known finance company. I've never made something this serious, I started out writing something like a bad spec, an overview of some sorts, and it has wasted a LOT of my time. Ive also made 3 mockup-kinda-thingies for my client so I have a good understanding of what they want. Also released a preview (a throw away working app with the most basic workflow), and Ive only written and tested some of the very core/base systems. I think the mistake Ive been making so far is not writing a detailed spec, so Im getting to it now. So the whole thing comprises of An MVC website (for admins & data viewing) 2 Silverlight modules (For 2 specific tasks) 1 Desktop Application Im totally short on time, resources and need to get this done quick, also, need to make sure these guys read it up equally quick and painlessly. So how do I go about it, Im looking for any tips, any real world stuff, how do you guys usually do it? Do you make a mock screenie of every dialog/form/page? Im thinking of making a dummy asp.net web forms project, then filling in html files in folders and making it look like my mvc url structure. Then having a section in the spec for the website and write up a page for every URL Ive got with a screenie. For my win forms app, Ive made somewhat of a demo Win Form project, would I then put in a dialog or stucture everything as I would in the real app and then screen shot it?

  • How to start gnome-shell?

  • Closed-loop Recommendation Engines: Analyst Insight report on Oracle Real-Time Decisions (RTD)

    - by Mike.Hallett(at)Oracle-BI&EPM
    In November 2011, Helena Schwenk of MWD Advisors, published her analysis on Oracle Real-Time Decisions.  She summarizes as follows: "In contrast to other popular approaches to implementing predictive analytics, RTD focuses on learning from each interaction and using these insights to adjust what is presented, offered or displayed to a customer. Likewise its capabilities for optimising decisions within the context of specific business goals and a report-driven framework for assessing the performance of models and decisions make it a strong contender for organisations that want to continuously improve decision making as part of a customer experience marketing, e-commerce optimisation and operational process efficiency initiative." This is an outstanding report to share with a prospect or client as it goes into great detail about the product and its capabilities.  It also highlights the differences in Oracle's Real-Time Decisions product vs. other closed loop recommendation engines. I encourage you to share this report with your clients and prospects. It can be downloaded directly from here - MWD Advisors Vendor Profile: Oracle Real-Time Decisions. (expires in November 2012) Highlights: "At the core of RTD lies a learning engine that combines business rules and adaptive predictive models to deliver recommendations to operational systems while simultaneously learning from experiences." "While closed-loop recommendation engines are becoming more prevalent... there are a number of features that distinguish RTD: It makes its decisions in the context of the business objectives, such as maximising customer revenue or reducing service costs Its support for operational integration offers organisations some flexibility in how they implement the offering."

  • lucid 10.04 LTS => Precise 12.04.1 : upgrade doesn't work

    - by Rastom
    I googled and looked into all unkown issues on ubuntu forums but I can't figure out why a 10.04 LTS server won't detect the last LTS 12.04.1. I guess since 12.04 is a fresh dist, not much is reported for related issues Here is what I did : apt-get update apt-get upgrade apt-get install update-manager-core it was already installed so no update for this package. I checked : /etc/update-manager/release-upgrades [DEFAULT] # Default prompting behavior, valid options: # # never - Never check for a new release. # normal - Check to see if a new release is available. If more than one new # release is found, the release upgrader will attempt to upgrade to # the release that immediately succeeds the currently-running # release. # lts - Check to see if a new LTS release is available. The upgrader # will attempt to upgrade to the first LTS release available after # the currently-running one. Note that this option should not be # used if the currently-running release is not itself an LTS # release, since in that case the upgrader won't be able to # determine if a newer release is available. Prompt=lts I also checked my sourcelist before running apt-get : /etc/apt/sources.list deb http://archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ lucid-security main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ lucid-updates main restricted universe multiverse deb http://security.ubuntu.com/ubuntu lucid-security main restricted deb-src http://security.ubuntu.com/ubuntu lucid-security main restricted deb http://security.ubuntu.com/ubuntu lucid-security universe deb-src http://security.ubuntu.com/ubuntu lucid-security universe deb http://security.ubuntu.com/ubuntu lucid-security multiverse deb-src http://security.ubuntu.com/ubuntu lucid-security multiverse # deb http://landscape.canonical.com/packages/hardy ./ # deb-src http://landscape.canonical.com/packages/hardy ./ and then following Ubuntu guide for Precise upgrade the command below should work : root@xxxxxxxxx:/etc/apt# do-release-upgrade -d Checking for a new ubuntu release No new release found So am I missing something ? The server was accessing outside through a proxy but I grant direct access to this server to avoid any Internet access problem or redirection but no clue... Any help would be appreciated

  • Keeping multiple root directories in a single partition

    - by intuited
    I'm working out a partition scheme for a new install. I'd like to keep the root filesystem fairly small and static, so that I can use LVM snapshots to do backups without having to allocate a ton of space for the snapshot. However, I'd also like to keep the number of total partitions small. Even with LVM, there's inevitably some wasted space and it's still annoying and vaguely dangerous to allocate more. So there seem to be a couple of different options: Have the partition that will contain bulky, variable files, like /srv, /var, and /home, be the root partition, and arrange for the core system state — /etc, /usr, /lib, etc. — to live in a second partition. These files can (I think) be backed up using a different backup scheme, and I don't think LVM snapshots will be necessary for them. The opposite: putting the big variable directories on the second partition, and having the essential system directories live on the root FS. Either of these options require that certain directories be pointers of some variety to subdirectories of a second partition. I'm aware of two different ways to do this: symlinks and bind-mounts. Is one better than the other for this purpose? Is there another option? Do any of the various Ubuntu installation media/strategies support this style of partition layout?

  • 5 Ways Microsoft Can Improve the Windows 8 Start Screen

    - by Matt Klein
    After having used Windows 8 over the past few months, we’ve found a few ways Microsoft could immediately improve the Start Screen to make it less disorienting and more usable, not only for tablets but desktops and laptops as well. It’s safe to say that the one thing Windows 8 doesn’t lack is criticism. Since the Consumer Preview debuted in February, it has proven to be one of the most polarizing Windows releases ever. But regardless of whether you love or hate it, Windows 8 is where Microsoft’s venerable operating system is headed. Portable computing is here to stay and if the company is to survive, let alone remain relevant, it has to change, adapt, embrace, and extend. Perhaps the single most universally controversial change to Windows is Microsoft’s decision to remove the Start button (or orb, if you’ve moved beyond XP) and with it, what we know to be the Start Menu. In their place we now have a Start hot corner (a workable alternative) and the newly redesigned Metro Start Screen. The Start Screen is, if nothing else, different. Beyond a doubt, there has not been such a radical redesign of Windows’ Start functionality since it went to a two-column design with a nested “All Programs” menu in Windows XP. The Start Screen can be a little jarring because it requires users to not only relearn what they’ve known for nearly two decades but to also rethink the way they interact with Windows. However, the Start Screen maintains its core elements: a Start “menu”, a place for all installed programs (All apps), and a search pane. The Start Screen is attractive, clean, bold, and very imperfect. Here are five changes we’d like to see in the Start Screen before Windows 8 goes gold … How to Make Your Laptop Choose a Wired Connection Instead of Wireless HTG Explains: What Is Two-Factor Authentication and Should I Be Using It?

  • Ubuntu 13.10 Installing MariaDB when Apt reports MariaDB has unmet dependencies or broken packages

    - by Ecaz
    I have tried everything to install MariaDB on this clean Ubuntu installation but I keep getting this error, Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: mariadb-server : Depends: mariadb-server-5.5 (= 5.5.33a+maria-1~saucy) but it is not going to be installed E: Unable to correct problems, you have held broken packages. I have followed this guide to try and install it, http://www.unixmen.com/install-lemp-server-nginx-mysql-mariadb-php-ubuntu-13-10-server/ And I have also followed the "official" guide on the MariaDB downloads page for 13.10 https://downloads.mariadb.org/mariadb/repositories/ But nothing seems to be working. Edit 1 I have tried both How do I resolve unmet dependencies? and How to install MariaDB? but it still gives me the error I posted above. It's a fresh Ubuntu install with hardly anything installed. Edit 2 All the check boxes are ticket in Updates. I ran: sudo apt-get update && sudo apt-get -f install mariadb-server-5.5"=5.5.33a+maria-1~saucy" And it gave me this error: The following packages have unmet dependencies: mariadb-server-5.5 : Depends: mariadb-client-5.5 (>= 5.5.33a+maria-1~saucy) but it is not going to be installed Depends: mariadb-server-core-5.5 (>= 5.5.33a+maria-1~saucy) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

  • Please recommend a patterns book for iOS development

    - by Brett Ryan
    I've read several books on iOS development and Objective-C, however what a lot of them teach is how to work with interfaces and all contain the model inside the view controller, i.e. a UITableViewController based view will simply have an NSArray as it's model. I'm interested in what the best practices are for designing the structure of an application. Specifically I'm interested in best practices for the following: How to separate a model from the view controller. I think I know how to do this by simply replacing the NSArray style example with a specific model object, however what I do not know how to do is alert the view when the model changes. For example in .NET I would solve this by conforming to INotifyPropertyChanged and databinding, and similarly with Java I would use PropertyChangeListener. How to create a service model for my domain objects. For example I want to learn the best way to create a service for a hypothetical Widget object to manage an internal DB and also services for communicating with remote endpoints. I need to learn the best ways to do this in a way that interface components can subscribe to events such as widgetUpdated. These services should be singleton classes and some how dependency injected into model/controller objects. Books I've read so far are: Programming in Objective-C (4th Edition) Beginning iOS 5 Development: Exploring the iOS SDK The iOS 5 Developer's Cookbook: Expanded Electronic Edition: Essentials and Advanced Recipes for iOS Programmers Learn Objective-C on the Mac: For OS X and iOS I've also purchased the following updated books but not yet read them. The Core iOS 6 Developer's Cookbook (4th edition Programming in Objective-C (5th Edition) I come from a Java and C# background with 15 years experience, I understand that many of the ways I would do things in these languages may not fit to the ObjC way of developing applications. Any guidance on the topic is very much appreciated.

  • Can AJAX in a CMS slow down your server

    - by Saif Bechan
    I am currently developing some plugins for WordPress, and I was wondering which route to take. Let's take an example, you want to display the last 3 tweets on your page. Option 1 You do things the normal way inside WordPress. Someone enters the website, while generating the page, you fetch the tweets in php via the twitter api, and just display them where you want. Now the small problem with this is, that you have to wait for the response from twitter. This takes a few ms. NO real problem, but this is question is just out of curiosity. Option 2 Here you don't do anything in WordPress on the initial load, but you do have the API inside. Now you just generate the page, and as soon as the page is done on the client side, you do a small AJAX call back to the server via a WordPress plugin, to fetch your latest tweets. Also called asynchronously. Now the problem with this IMO is that you have much more stress on your server. For starters you have two HTTP requests instead of one. Secondly the WordPress core has to load two times instead of one. Other options Now I know there are a lot of other options: 1) Getting the tweets directly via javascript, no stress on the server at all. 2) Cache the tweets so they are fetched from the DB instead of using the API every time. 3) Getting the tweets from an ajax call that is not a WordPress plugin. 4) Many more. My Question Now my question is if you only compare 1 and 2, which would be a better choice.

Two pieces of the jigsaw are: I've created a "Whiley Builder" by subclassing incremental project builder. This handles building and cleaning of "*.whiley" files. I've created a content-type called "Whiley Source Files" for "*.whiley" files, which extends "org.eclipse.jdt.core.javaSource" (this follows Andrew Eisenberg suggestion). The advantage of having the content-type extend javaSource is that it immediately fits into the package explorer, etc. In principle, I could fleshout ICompilationUnit to provide more useful info, although I haven't done that yet. The disadvantage is that the Java builder is trying to compile my whiley files ... and it obviously can't. Originally, I had the Java Builder run first, then the Whiley builder. Superficially, this actually worked out quite well since all of the errors from the Java Builder were discarded by the Whiley Builder (for whiley files). However, I actually want the Whiley Builder to run first, as this is the best way for me to resolve dependencies between Java and Whiley files. Which leads me to my question: can I stop the Java builder from trying to compile certain java-like resources? Specifically, in my case, those with the "*.whiley" extension. As an alternative, I was wondering whether my Whiley Builder could somehow update the resource delta to remove those files which it has dealt with. Thoughts?

  • How to Properly Make use of Codeigniter's HMVC

    - by Branden Stilgar Sueper
    I have been having problems wrapping my brain around how to properly utilize the modular extension for Codeigniter. From what I understand, modules should be entirely independent of one another so I can work on one module and not have to worry about what module my teammate is working on. I am building a frontend and a backend to my site, and am having confusion about how I should structure my applications. The first part of my question is should I use the app root controllers to run modules, or should users go directly to the modules by urls? IE: in my welcome.php public function index() { $this->data['blog'] = Modules::run( 'blog' ); $this->data['main'] = Modules::run( 'random_image' ); $this->load->view('v_template', $this->data); } public function calendar() { $this->data['blog'] = Modules::run( 'blog' ); $this->data['main'] = Modules::run( 'calendar' ); $this->load->view('v_template', $this->data); } My second part of the question is should I create separate front/back end module folders -config -controllers welcome.php -admin admin.php -core -helpers -hooks -language -libraries -models -modules-back -dashboard -logged_in -login -register -upload_images -delete_images -modules-front -blog -calendar -random_image -search -views v_template.php -admin av_template.php Any help would be greatly appreciated.

  • Black Screen after Resume from Sleep (Kubuntu)

    - by user20271
    I know there is a lot of other posts like this, but I have been looking for hours and I still haven't found any solution. I have recently installed Kubuntu Linux along side my Windows 7, the sleep on my Win7 works fine and resumes like normal. When I am loaded into Kubuntu, and I put my laptop to sleep, it goes into sleep as normal. When I go to RESUME from the sleep, the screen stays solid black, it doesn't light up, no blinking curser or anything. The Wi-Fi light is 'off' (orange) and I cannot turn it on. The Caps lock and the Num lock lights on the keyboard blink slowly. I hear something on the inside of the computer start to spin. I am not very experienced with Kubuntu/Linux, but I do know a bunch of computer terminology, I am still far from an expert though. I have about 300GB designated to my Win7 stuff, and another partition with about 100GB for my Kubuntu Linux. My computers specs are as follows: Windows 7 64-bit I have the most recent version of Kubuntu because I just downloaded it a few days ago and updated it yesterday. AMD Athlon Duel-Core processor 4GB of RAM And it is a HP G61 Laptop

  • C# Adds Optional and Named Arguments

    Earlier this month Microsoft released Visual Studio 2010, the .NET Framework 4.0 (which includes ASP.NET 4.0), and new versions of their core programming languages: C# 4.0 and Visual Basic 10. In designing the latest versions of C# and VB, Microsoft has worked to bring the two languages into closer parity. Certain features available in C# were missing in VB, and vice-a-versa. Last week I wrote about Visual Basic 2010's language enhancements, which include implicit line continuation, auto-implemented properties, and collection initializers - three useful features that were available in previous versions of C#. Similarly, C# 4.0 introduces new features to the C# programming language that were available in earlier versions of Visual Basic, namely optional arguments and named arguments. Optional arguments allow developers to specify default values for one or more arguments to a method. When calling such a method, these optional arguments may be omitted, in which case their default value is used. In a nutshell, optional arguments allow for a more terse syntax for method overloading. Named arguments, on the other hand, improve readability by allowing developers to indicate the name of an argument (along with its value) when calling a method. This article examines how to use optional arguments and named arguments in C# 4.0. Read on to learn more!

  • Which platform to choose, Java or .NET?

    - by salman
    I am working in a private bank, a leading mid size bank in local market. We are going to create our core banking solution. Existing solution has been developed on Java using IBM Visual Age 4.0. It is very important to discuss architecture first, we have currently more than 350 branches working in standalone mode, and it means they are working in self contained environment. They have their own database server (IBM DB2 9.7) and they are communicating with other branches via sockets to send and receive data. Having experience of .NET for more than 5 years I am trying to convince my superiors to choose .NET platform, but they are reluctant and unwilling. It is my job to encourage them for choosing best available platform to create large scale enterprise application. In simple word, we are going to create a very large scale enterprise financial application, a centralize and integrated which connects all branch networks plus having scalable, solid architecture that easily evolve over time. I want professional people to comment on above scenarios. Which platform to choose .NET or Java? Our all resource is currently working in Java, we have homogeneous environment (no Linux, no Mac and no UNIX). Any idea, any thoughts, any points technical or non-technical i.e. administrative or management point of view will be really appreciated.
