  • Firefox 12's hardware acceleration on Ubuntu 12.04 LTS

    - by user64943
    After I have installed Ubuntu 12.04 LTS (32 bits), Firefox 12 works fine but without hardware acceleration. Needless to say I have the latest nVidia's proprietary drivers installed and my Firefox Preferences, on "Advanced" tab, "Browsing" section, have the option "Use hardware acceleration when available" checked. I have tried the following things before asking this question: Creating a boolean key "webgl.force-enabled" and set it to true on Firefox's page about:config; Starting a new profile like commented on thread Mozilla Firefox 12 is very slow on Ubuntu 12.04 LTS; I have updated my nVidia driver to version 295.53. And none of this have worked. As you can see below in my Firefox's page about:support report, "Graphics" section shows no "GPU Accelerated Windows": Adapter Description NVIDIA Corporation -- GeForce GTX 460/PCIe/SSE2 Vendor ID NVIDIA Corporation Device ID GeForce GTX 460/PCIe/SSE2 Driver Version 4.2.0 NVIDIA 295.53 WebGL Renderer NVIDIA Corporation -- GeForce GTX 460/PCIe/SSE2 -- 4.2.0 NVIDIA 295.53 GPU Accelerated Windows 0 AzureBackend skia I use the following site to test hardware acceleration: http://ie.microsoft.com/testdrive/Performance/FishBowl/ On Windows 7 I get 60 fps even with 1,750 fishes on browser's Full Screen Mode (1680x1050x32bit-color). On Ubuntu 12.04 LTS, same nVidia drivers (as shown in report), won't go faster than 15 fps with only 1,000 fishes. Can anybody help me? Best Regards,

  • Bad Spot to Be In: Playing Catch-up with Mobile Advertising

    - by Mike Stiles
    You probably noticed, there’s a mass migration going on from online desktop/laptop usage to smartphone/tablet usage.  It’s an indicator of how we live our lives in the modern world: always on the go, with no intention of being disconnected while out there. Consequently, paid as it relates to mobile advertising is taking the social spotlight. eMarketer estimated that in 2013, US adults would spend about 2 hours, 21 minutes a day on mobile, not counting talking time. More people in the world own smartphones than own toothbrushes (bad news I suppose if you’re marketing toothpaste). They’re using those mobile devices to access social networks, consuming at least 17% of their mobile time on them. Frankly, you don’t need a deep dive into mobile usage stats to know what’s going on. Just look around you in any store, venue or coffee shop. It’s really obvious…our mobile devices are now where we “are,” so that’s where marketers can increasingly reach us. And it’s a smart place for them to do just that. Mobile devices can be viewed more and more as shopping facilitators. Usually when someone is on mobile, they are not in passive research mode. They are likely standing near a store or in front of a product, using their mobile to seek reassurance that buying that product is the right move. They are the hottest of hot prospects. Consider that 4 out of 5 consumers use smartphones to shop, 52% of Americans use mobile devices for in-store for research, 70% of mobile searches lead to online action inside of an hour, and people that find you on mobile convert at almost 3x the rate as those that find you on desktop or laptop. But what are marketers doing? Enter statistics from Mary Meeker’s latest State of the Internet report. Common sense says you buy advertising where people are spending their eyeball time, right? But while mobile is 20% of media use and rising, the ad spend there is 4%. Conversely, while print usage is at 5% and falling, ad spend there is 19%. We all love nostalgia, but come on. There are reasons marketing dollar migration to mobile has not matched user migration, including the availability of mobile ad products and the ability to measure user response to mobile ads. But interesting things are happening now. First came Facebook’s mobile ad, which let app developers pay to get potential downloads. Then their mobile ad network was announced at F8, allowing marketers to target users across non-Facebook apps while leveraging the wealth of diverse data Facebook has on those users, a big deal since Nielsen has pointed out mobile apps make up 89% of the media time spent on mobile. Twitter has a similar play in motion with their MoPub acquisition. And now mobile deeplinks have arrived, which can take users straight to sub-pages of mobile apps for a faster, more direct shopper/researcher user experience. The sooner the gratification, the smoother and faster the conversion. To be clear, growth in mobile ad spending is well underway. After posting $13.1 billion in 2013, Gartner expects global mobile ad spending to reach $18 billion this year, then go to $41.9 billion by 2017. Cheap smartphones and data plans are spreading worldwide, further fueling the shift to mobile. Mobile usage in India alone should grow 400% by 2018. And, of course, there’s the famous statistic that mobile should overtake desktop Internet usage this year. How can we as marketers mess up this opportunity? Two ways. We could position ourselves in perpetual “catch-up” mode and keep spending ad dollars where the public used to be. And we could annoy mobile users with horrid old-school marketing practices. Two-thirds of users told Forrester they think interruptive in-app ads are more annoying than TV ads. Make sure your brand’s social marketing technology platform is delivering a crystal clear picture of your social connections so the mobile touch point is highly relevant, mobile optimized, and delivering real value and satisfying experiences. Otherwise, all we’ve done is find a new way to be unwanted. @mikestiles @oraclesocialPhoto: Kate Mallatratt, freeimages.com

  • Developing professionally for iOS, Android and web - an insight

    - by Scott Roberts
    This is not really a question on how to develop all three, I know various cross platform ways and so on. But I more want to know from developer standpoint how hard it is to basically develop iOS, Android and web apps? I am currently in my first job as a mobile/web developer. I have already developed my first iPhone/iPad app and now I have to develop the app for android because the web version I tried just didn't perform as well as needed and web databases just did not seem to make the cut. But I am not sure it's possible to be good at developing all 3 in terms of remembering all the api's etc. I wouldn't say I have an issue with the programming languages just how to use the api's for the various platforms. Also, all the other languages I look at, in my spare time, just feel like I am spreading myself to thin. Is it feasible for one person to be developing ios, android and web apps? Should I think about reducing it to iOS and web based apps? I develop everything by myself, so I have no one to discuss what the best solutions are for everything and I am just trying to workout as I go along. So any cross platform developers out there? Do companies have different teams for different platforms? Any insight would just help me get my head together. Hopefully this question makes sense.

  • Choosing the right language for the job

    - by Ampt
    I'm currently working for a company on the engineering team of about 5-6 people and have been given the job of heading up the redesign of an embedded system tester. We've decided the general requirements and attributes that would be desirable in the system, and now I have to decide on a language to use for the system, or at the very least come up with a list of languages with pros and cons to present to the team. The general idea of the project is that we currently have a tester written in c++, which was never designed to be a tester, but instead has evolved to be such over the course of 3-4 years due to need. Writing tests for a new product requires modifying the 'framework' and writing code that is completely non-human readable or intuitive due to the way the system was originally designed. Now, we've decided that the time to modify this tester for each new product that we want to test has become too high and want to partially re-write the system so that we can program the actual tests in a scripting language that would then use the modified c++ framework on the back end to test the actual systems. The c++ framework would be responsible for doing all the actual work and the scripting language would just integrate with that to tell the framework what to do. Never having programmed in a scripting language (we program embedded systems), I've run into a wall where I have no experience with any of the languages that we could possibly use, but must somehow give pros and cons of each language so that we can choose the best one for the job. Currently my short list of possibilities includes: Python TCL Lua Perl My question is this: How can a person evaluate a language that he/she has never used before? What criteria are good indicators for a languages potential usability on a project? While helpful suggestions for my particular case are appreciated, I feel that this is a good skill to possess and would like to be able to apply this to many different projects if at all possible

  • Organizing Business and Presentation entities

    - by simoneL
    Background I am developing a WPF project. This is the basic structure: User Interface (WPF Project); Interfaces (class library, contains all the interfaces and the entities used by the application; Modules (every module contains the logic of a specific argument, e.g. File Management, and can eventually contains Wpf User Controls). In the WPF Controls, to facilitate the binding operations I have created a BaseViewModel class which contains a Raise method that automates the binding mechanism (for further details, I used a technique similar to that one described in this article). The problem Understand which is the best way to separate Presentation form from the Business form in the entities classes. The case In the Interfaces project I have, for instance, the class User public class User { public virtual string Name { get; set; } // Other properties } In one of the modules I need to use the User class and to bind its properties to the User Interface controls. To do so I have to use a custom implementation of the get and set keywords. At first point, I thought to create a class in the Module called, for instance, ClientUser and override the properties that I need: public class ClientUser : User { private string name; public override string Name { get { return name; } set { Raise(out name, value); } } // Other properties } The problem is the Raise method, which is declared in the BaseViewModel class, but due to C# single inheritance constraint, I can't inherit from both classes. Which is the right way to implement this architecture?

  • Should a database server be in a different VM instance as an application?

    - by orokusaki
    I'm setting up a database server as a separate VM in my server so that I can control resources, and make backups of just that instance. I own a server that will reside in a colo soon. Is this the best way to approach my DB regarding scalability? Are there any security concerns? Do I listen at localhost still, even though it's a separate instance? And, is there any benefit to running your DB (PostgreSQL in my case) in the same machine as your application (web based SAAS application in my case)?

  • Numbered list with subclauses

    - by Barry Clearwater
    I'm trying to create a legal document with decimal numbered subclauses, then alpha and roman subsub and subsubsub clauses. (whew!) `1. MAIN HEADING 1.1 This is an example of a sub-clause and you can see that even though the words continue on to the right, it would be best if it wrapped around and formed a block to the right of the decimal number 1.2 In doing so the normal second clause should also wrap around but the second subsequent clause should hang in from the left and be in a block. See below for the remaining clauses (a) this list is completely for demonstration and should not be construed as legal language in any way, nor should make sense in that (b) should the indentation take more than: i) this many lines it would be overly big 11) legal numbering continues in the sub-sub clauses with the use of lower roman lettering and should flow below in a block iii) and continue the formatting on to the next line but be underneath the body of the the text and not begin directly below the number itself. In this example the text carries out to the right but I need it to wrap around underneath. Sorry its so wordy, need this to show the example. 2. Second Clause Heading 2.1 and so it continues thus I've found the examples for decimal numbering but they do not create a block out to the right of the number, and they carry on with multiple decimals rather than alpha and roman sub clauses.

  • C# XNA: Effecient mesh building algorithm for voxel based terrain ("top" outside layer only, non-destructible)

    - by Tim Hatch
    To put this bluntly, for non-destructible/non-constructible voxel style terrain, are generated meshes handled much better than instancing? Is there another method to achieve millions of visible quad faces per scene with ease? If generated meshes per chunk is the way to go, what kind of algorithm might I want to use based on only EVER needing the outer layer rendered? I'm using 3D Perlin Noise for terrain generation (for overhangs/caves/etc). The layout is fantastic, but even for around 20k visible faces, it's quite slow using instancing (whether it's one big draw call or multiple smaller chunks). I've simplified it to the point of removing non-visible cubes and only having the top faces of my cube-like terrain be rendered, but with 20k quad instances, it's still pretty sluggish (30fps on my machine). My goal is for the world to be made using quite small cubes. Where multiple games (IE: Minecraft) have the player 1x1 cube in width/length and 2 high, I'm shooting for 6x6 width/length and 9 high. With a lot of advantages as far as gameplay goes, it also means I could quite easily have a single scene with millions of truly visible quads. So, I have been trying to look into changing my method from instancing to mesh generation on a chunk by chunk basis. Do video cards handle this type of processing better than separate quads/cubes through instancing? What kind of existing algorithms should I be looking into? I've seen references to marching cubes a few times now, but I haven't spent much time investigating it since I don't know if it's the better route for my situation or not. I'm also starting to doubt my need of using 3D Perlin noise for terrain generation since I won't want the kind of depth it would seem best at. I just like the idea of overhangs and occasional cave-like structures, but could find no better 'surface only' algorithms to cover that. If anyone has any better suggestions there, feel free to throw them at me too. Thanks, Mythics

  • NCurses, scrolling of multiline items, "current item" pointer and "selected items"

    - by mjf
    I am looking for hints/ideas for the best (most effective) way on how to scroll multi-line items as well as emphasizing of the "current item" and "selected items" such as: 1 FOO ITEM 1 Foo sub-item 2 Foo sub-item 3 Foo sub-item 2 BAR ITEM 1 Bar sub-item 3 BAZ ITEM 1 Baz sub-item 2 Baz sub-item 4 RAB ITEM 5 ZZZ ITEM 1 Zzz sub-item 2 Zzz sub-item 3 Zzz sub-item 4 Zzz sub-item using NCurses (some combination of windows, sub-windows, pads, copywin? Uff! In fact, the lines could exceed the stdscr's width so that possibility to scroll left/right would be also nice - pads?)... The whole items (including the sub-items) are supposed to be emphasized as full-width window/pad areas. The "current item" (including it's set of lines) should be emphasized (i.e. using A_BOLD), selected set of items of choice (including the set of lines for each the selected item) should be emphasized in another way (i.e. using A_REVERSE). What would you choose to cope with it the most effective NCurses way? (The less redrawals/refreshes the better and terminal is supposed to have the ability to change it's size - such as XTerm running under "floating window" management.) Thank you for your ideas (or perhaps some piece of code where something similar is already solved - I was not able to find anything helpful on the Internet. I mean I am not going to copy/paste foreign code but programming NCurses properly is still somehow difficult to me). P.S.: Would you suggest to "smooth-scroll" +1/-1 screen line or rather "jump-scroll" +lines/-lines of the items? (I personally prefer the latter one.) Sincerely, -- mjf

  • What is the current state of development for the FLAC codec?

    - by TwentyMiles
    I have a pretty large collection of FLAC files created from my CD collection. I love the FLAC format and the sound quality that you can get from it. Lately, however, I've been trying to write a few tools to manipulate the files and I've been noticing what seems to be a stagnation of the community around the codec. Some of the links on the official FLAC page point to thing that are no longer relevant (7digital, for example, appears to no longer sell FLAC encoded songs). It's pretty hard to find hardware players that support FLAC any more (most noticeably it's not present on lower end players when it used to be, and playback is absent on Android). Programming language tools (Java and .NET libraries) are at best old, and at worst unfinished. What's the current state of FLAC development? Has it been replaced by another codec?

  • ECMP Load Balancing in JUNOS

  • Is It Time To Specialize?

    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/18/is-it-time-to-specialize.aspx Over my career I have made a living as a generalist.  I have been a jack of all trades and a master of none.  It has served me well in that I am able to move from one technology to the other quickly and make myself productive.  Where it becomes a problem is deep knowledge.  I am constantly digging for the things that aren’t basic knowledge.  How do you make a product like WCF or Windows RT do more than just “Hello World”? As an architect I need to be a jack of all trades.  This is what helps me to bring the big picture of a project into focus for developers with different skills to accomplish the goals of the project. It is a key when the mix technologies crosses Windows, Unix and Mainframe with different languages and databases.  The larger the company that the project is for the more likely this scenario will arise. As a consultant and a developer I need to have specialized skills in order to get the job done efficiently.  if I have a SharePoint or Windows Phone project knowing the object model details and possible roadblocks of the technology allow me to stay within budgets as well as better advise the client on technology decisions. What is the solution?  Constant learning and associating with developers who specialize in a variety of technologies is the best thing you can do.  You may have thought you were done with classes when you left college, but in this industry you need to constantly be learning new products and languages.  The ultimate answer is you must generally specialize.  Learn as many subject areas as possible, but go deep when ever you can.  Sleep is overrated.  Good luck. del.icio.us Tags: software development,software architecture,specialization,generalist

  • Powershell overruling Perl binmode?

    - by hippietrail
    I have a Perl script which creates a binary file while scanning a very large text file. It outputs to STDOUT which I redirect in the commandline to a file. To optimize it I'm making changes then seeing how low it takes to run. On Linux for this I use the "time" command. On Windows the best way to time a program seemed to be to PowerShell's "measure-command". This seemed to work fine but I noticed the generated files were larger. On examination I found that the files generated from within PowerShell begin with a BOM and contain CRLF pairs! My Perl script has a "binmode STDOUT" directive and does work correctly in a normal dosbox. Is this a bug or misfeature in PowerShell or measure-command? Has it affected others creating binary files by means other than Perl? Googling hasn't turned anything up so far. I'm using Perl 5.12, PowerShell v1.0 and Windows XP.

  • How can I auto-connect to a WPA2 Enterprise network?

    - by Demetri
    I would like my computer to automatically connect to a WPA2-Enterprise network as soon as it boots whenever the network is available, without any action needed by me. The computer already offers to connect, and even remembers the password, but I must still hit 'Enter' to connect. Also, connection does not occur if my login is at the terminal. I would like to automatically connect every time I login, no matter how I do so, unless a more preferred network is available. What is the best way to do this? I am running Fedora 19. A shell script that can be invoked at the terminal would be preferred. Connecting even if the Gnome-desktop has not launched is a must.

I know there is no built-in firewall and everyone recommends placing an ESXi machine behind a firewall, but when this is not an option... Is there any other option like using hosts.allow/deny or anything else? Or I better use ESX instead of ESXi? Edit: In the given circumstances, I am not able to add any additional hardware or use things like managed switches.

  • Keep context-configuration when redeploying via Cargo

    - by Björn Pollex
    I am using Tomcat 7 to host a web-application that requires a JNDI datasource to be set up. Because this resource is specific to this application, I would like to configure it inside the application-specific context-descriptor in $CATALINA_BASE/conf/[enginename]/[hostname]/. I am also using Cargo from Maven to deploy the web-application to Tomcat. The problem is that when I do a redeploy with Cargo, it first undeploys the application, before deploying it again. When undeploying it, Tomcat deletes the context-descriptor of the application, so it won't work after redeploying. I could of course package the context-descriptor with the application, but I would like to keep any such container-specifics out of the .war. Another alternative is to configure the datasource in the global context-descriptor, but that too seems wrong, because the datasource is supposed to be exclusive to my application. Is my approach fundamentally wrong? What is the best practice here? Is there any way to prevent Tomcat from deleting the descriptor when undeploying?

  • Combine Multiple Audio Files into a single higher-quality audio File

    - by namenlos
    BACKGROUND My team gave a demo to a large audience - we recorded the audio of the demo in multiple locations in the room (3) the audio was recorded using cheap laptop microphones I was not involved in the recording of the audio or the demo Both audio files suck in some form the first one is of a recording near the speaker - which clearly gets his voice but the the audience is audience is muffled - also this one is slightly noisy The second recording was done in the middle of the audience - it gets the audience questions clearly but actually gets the speaker rather sometimes well and sometimes poorly (not all the speakers spoke loudly enough to be heard) MY QUESTION Is there any techinque or software which can be used to merge these audio files in such a way that the best qualities of each are preserved. I am NOT asking now to simply merge them together in one track - I've already done that in Audacity and it is certainly better - what I am looking for could be considered closer to how HDR images are created - multiple exposures combined into an enhanced new version which is not simply an average of the inputs. NOTE Am not an "Audio" guy - just a normal user

  • CruiseControl.Net - not able to see Project Statistics

    - by Anders Juul
    Hi all, I've made a reinstallation of the buildserver and can no longer see the standard graphs of project statistics. The error message shown is "Missing/Invalid statistics reports. Please check if you have enabled the Statistics Publisher, and statistics have been collected atleast once after that." To the best of my knowledge, the ccnet.config file has not been changed in this respect and by inspection it is verified that I have a Statistics / statisticsList-section for the project. Furthermore, the values appear in the Artifacts\statistics.csv and Artifacts\report.xml files. My guess would then be StatisticsGraph.xslt, which I have copied fresh from distribution to both Server\xlst and WebDashboard\xslt (why are they located in both places, by the way!?). Rebuild and check - still same error message. Any hints to how to debug this would be appreciated!

  • Need assistance matching a general theme style as well as eCommerce capability

    - by humble_coder
    I'm in the process of acquiring a new design client. They are getting into the business of "auto parts wholesaling" and they want a storefront. My preference is/was to create something from scratch. However, here is an established trend in their particular market (similar parts, layout, etc). They insist on following the existing visual trend, as per the following: http://www.xtremediesel.com/ http://www.thoroughbreddiesel.com/ http://www.alligatorperformance.com/ My plan of attack at this point is to find a comparable WP theme and a flexible (but useful) backend/product management. Their current demo site (which their previous developer made a stab at) is using Pinnacle Cart. It is no where near what they need, nor is it intuitive to work with. I was actually considering Magento for its greater abilities but I'm still considering options. That said, my two primary dilemmas are as follows: 1) I need a theme that mimics the general style of those listed. They explicitly said they didn't want anything too clean (e.g. ThemeForest, Woothemes) as it "wasn't rugged or busy looking enough" for their field. 2) I need a WP/Magento/WP e-Commerce (or any one of a host of other) plugin that will allow for bulk import/update of nearly 200,000 products, descriptions and images. I'm not opposed to manually interfacing with the DB for import, but in the end, I need a store/system that doesn't needlessly add 50 tables to accommodate some "wet behind the ears" concept of table normalization and is easy to add to. Anyway, if anyone has any quality suggestions regarding either of these issues, it would be most appreciated. Best.

  • How can I support objects larger than a single tile in a 2D tile engine?

    - by Yheeky
    I´m currently working on a 2D Engine containing an isometric tile map. It´s running quite well but I'm not sure if I´ve chosen the best approach for that kind of engine. To give you an idea what I´m thinking about right now, let's have a look at a basic object for a tile map and its objects: public class TileMap { public List<MapRow> Rows = new List<MapRow>(); public int MapWidth = 50; public int MapHeight = 50; } public class MapRow { public List<MapCell> Columns = new List<MapCell>(); } public class MapCell { public int TileID { get; set; } } Having those objects it's just possible to assign a tile to a single MapCell. What I want my engine to support is like having groups of MapCells since I would like to add objects to my tile map (e.g. a house with a size of 2x2 tiles). How should I do that? Should I edit my MapCell object that it may has a reference to other related tiles and how can I find an object while clicking on single MapCells? Or should I do another approach using a global container with all objects in it?

  • Can I use access used by Visual Basic for building a database [on hold]

    - by user3413537
    I am the only programmer where I work (summer job) and I am a student with only a few years of programming experience. So I was asked to build a database and I am very excited about this project because hopefully I can learn a lot from this. Using this database my manager is supposed to be able to assign work (dealing with businesses) to different people within the company using an interface (all workers have a shared drive). When workers are done with that paperwork related to the business, they can check off that its done, add comments at the bottom of the interface, and then move on to the next business. The only experience I've had with databases is some querying with SQL, and I've built GUI interfaces with JAVA. The information on the interface will be populated from Excel so workers know what businesses they are dealing with. I've done some research and I believe the best way to build this would be building a GUI using Microsoft Visual Studio (Visual Basic) first, then figuring out a way to populate the Interface from Excel. Also because the data is pretty straight forward and not complicated I will be using MS Access to store and track the database. I know this won't be easy, but for all you geniuses out there, is this on the right path? Thanks.

    I'm trying to figure out what are currently the two most efficent algorithms that permit, starting from a L/R pair of stereo images created using a traditional camera (so affected by some epipolar lines misalignment), to produce a pair of adjusted images plus their depth information by looking at their disparity. Actually I've found lots of papers about these two methods, like: "Computing Rectifying Homographies for Stereo Vision" (Zhang - seems one of the best for rectification only) "Three-step image recti?cation" (Monasse) "Rectification and Disparity" (slideshow by Navab) "A fast area-based stereo matching algorithm" (Di Stefano - seems a bit inaccurate) "Computing Visual Correspondence with Occlusions via Graph Cuts" (Kolmogorov - this one produces a very good disparity map, with also occlusion informations, but is it efficient?) "Dense Disparity Map Estimation Respecting Image Discontinuities" (Alvarez - toooo long for a first review) Anyone could please give me some advices for orienting into this wide topic? What kind of algorithm/method should I treat first, considering that I'll work on a very simple input: a pair of left and right images and nothing else, no more information (some papers are based on additional, pre-taken, calibration infos)? Speaking about working implementations, the only interesting results I've seen so far belongs to this piece of software, but only for automatic rectification, not disparity: http://stereo.jpn.org/eng/stphmkr/index.html I tried the "auto-adjustment" feature and seems really effective. Too bad there is no source code...
