• Apple Cinema Display 23" and grub

  - by Joshua Pruitt

  As per the title, I'm running my display on an older 23" Apple Cinema Display (because I still love it, darn it). I'm pushing it with an ATI Radeon DVI dual-link PCIe card. It works just fine, except GRUB doesn't seem able to push out the 1920x1200 pixel resolution needed in order to show me a boot menu! So..., I keep a smaller second monitor connected as the primary display so that I can see the boot menu and boot the system (I don't use that display once booted). This is a goofy work-around, and I'd like to just use my single display exclusively to boot the machine. I found some grub codes for higher resolutions, but not for 1920x1200. Is it capable of this? Did I just miss it? Thanks in advance!!!

• Why does my model render differently than its preview?

  - by Raven Dreamer

  I've been importing .fbx files that I made with 3DS Max 2012 into Unity, and it's quite neat to see my models running around in game. However, I can't help but notice that the models, as they're rendered in game, vary substantially from what they look like in the preview (and also what they looked like in 3DS Max). Observe: In-Game Unity Preview 3DS Max My gut tells me that I'm not setting up Unity's lighting system properly. What, then, do I need to do, to either my scene or my model, in order to get the left-most picture to look like the middle one?

• Best tool to recover removed files

  - by plua

  Using Ubuntu 10.10, I have a startup script that automatically removes my 'working directory'. This is a simple folder on my Desktop where I place a bunch of files that I use throughout the day. These are temporary files I need to store just for that one session. In order to keep things clean, my startup script does: rm -rf /home/user/Desktop/workdir mkdir /home/user/Desktop/workdir Works great. Till the moment I had some important files there and forgot to move them before shutting down. A few (2-3) sessions ago this happened and I now realize I need to recover the "workdir" directory. But several new ones have been created and removed in the meantime. What is the best way to recover this - if possible? I read about tools like scalpel but it seems they will scan my whole HD. I know the name of the folder and would like to just look for this workdir folder. What is best?

• What is the proper jargon to refer to a variable wrapped inside a function closure?

  - by Rice Flour Cookies

  In JavaScript, there is no such thing as a "private" variable. In order to achieve encapsulation and information hiding in JavaScript, I can wrap a variable inside a function closure, like so: var counter = (function() { var i = 0; var fn = {}; fn.increment = function() { i++; }; fn.get = function() { return i; }; return fn; {)(); counter.increment(); counter.increment(); alert(counter.get()); // alerts '2' Since I don't call i a private variable in JavaScript, what do I call it?

• PHP to SharePoint roadmap

  - by Daryl Gubler

  I'm a PHP developer with familiarity with Rails and a focus on MVC development. My company is moving more and more to SharePoint and I feel I need to learn to build application within the SharePoint system. I have some brief introduction to C# but that's about it. I've used some SharePoint Designer and the web interface but not that heavily (most of my "development" so far for SharePoint has been html/css/javascript page manipulation in SPDesigner). What, and in what order should I be learning to eventually develop applications for SharePoint? Also, any good resources for each step?

• HTML Canvas: Should my app x, y values be global?

  - by Joe

  I have a large file of functions. Each of these functions is responsible for drawing a particular part of the application. My app has x and y parameters that I use in the setup function to move the whole app around in order to try different placements. So, naturally, I need to use these x and y values to anchor each function's component rendering so that everything moves in unison if the global x,y values ever change. My question is, is it bad practice/architecture to have these x,y values in the global namespace and having the each function directly access them like so? function renderFace() { var x = App.x; var y = App.y; // drawing here } is there a better way i'm missing?

• Republishing blog posts on a popular website

  - by Giorgi

  I started my blog about programming yesterday and in order to promote and increase traffic I submitted my rss to Codeproject which pulls my posts and publishes them at Codeproject. While it increases the number of people reading my posts (but they are reading it at codeproject) I am worried that Google will penalize my site for duplicate content (Especially considering that Codeproject has much more reputation compared to my new website). The post at Codeproject has a link back to my blog post but it does not have "rel=canonical". So my question which one is better: a link from a high reputation website and some traffic or should I remove it from codeproject so that my blog is not penalized? What if codeproject adds "rel=canonical" to the link?

• usage of setPropertyListener and setActionListener

  - by Vijay Mohan

  The incorrect usage could lead to hard-to-debug problems so better to understand the fundamentals behind it's working.setpropertyListener queues an event on the server side, so if for a command component you have a showPopup behavior/actionListner as well as setPropertyListener then fwk does the queuing correctly and raises further event on the component. While, the setactionListener simply raises an event on the server side instead of queueing it, so any further event on command component gets cancelled.Also, if you use an ActionListener and showPopup behavior together on a command component, then the order of their invocation is undetermined and also one of event gets cancelled on the component. So, either use only actionListner and do the popup invocation stuff progrmmatically in your bean or use the declarative stuff logically so that no clash of event happens.

• What technology should I concentrate on for mobile development? [closed]

  - by Rob2211

  Firstly, I have many years experience with C# & .NET and some with Java. But, rather than committing to Java and developing native applications for Andriod I have been researching cross-platform deployment technologies. Currently, the most powerful cross-platform technology seems to be Flash, using Adobe AIR to package software as native applications. But given Adobe's announcement that it will discontinue support for the Flash Player on mobile devices it seems foolish (at this late stage) to invest in Flash and ActionScript as a developer. There has been speculation that Microsoft are also planning their exit strategy for Silverlight in favour of HTML5. So, my questions are; What is the most appropriate technology to invest in and learn in order to build cross-platform mobile applications / games while future proofing my skills as a developer? Is HTML5 mature enough to fill the 'Flash void' and be used to start building cross-platform, rich, interactive, networked mobile applications / games now? N.B. For HTML5 read (HTML5/CSS3/JavaScript)

• Open Grid Engine or Akka/Something more fault tolerant?

  - by Mike Lyons

  My use case is that I have a pipeline of independent, stand alone programs, that I want to execute in a certain order on specific pieces of data that our output from previous pipeline stages. The pipeline is entirely linear and doesn't do anything in terms of alternate paths through the pipe. I'm currently using SGE to do this and it works OK, however occasionally a job will overstep it's memory bounds, fail, and all jobs that require that output data will fail. The pipe needs to be restarted in that case, and it seems that whatever is providing the fault tolerance in akka might solve that for me?

• How can I create a symlink to the location that Ubuntu 10.10 mounts a CD?

  - by Michael Curran

  In Ubuntu 10.10, when I insert a CD or DVD into my optical drive, the system mounts the CD in a folder called /media/XYZ where XYZ is the disk's label. This has cause problems with Wine, as in order for an application to verify that an application's CD is present, Wine uses a symlinks to point to a mounted CD's folder. In this case, that folder must be /media/XYZ, but when using a different application, the folder would be different. I would like to know if there is a way to create a symlink that will always point to the mounted folder from a given /dev/cdrom* device, or how to force the system to always mount CDs to the same address (i.e. /media/cdrom).

• What features would you like to have in PHP? [closed]

  - by StasM

  Since it's the holiday season now and everybody's making wishes, I wonder - which language features you would wish PHP would have added? I am interested in some practical suggestions/wishes for the language. By practical I mean: Something that can be practically done (not: "I wish PHP would guess what my code means and fix bugs for me" or "I wish any code would execute under 5ms") Something that doesn't require changing PHP into another language (not: "I wish they'd drop $ signs and use space instead of braces" or "I wish PHP were compiled, statically typed and had # in it's name") Something that would not require breaking all the existing code (not: "Let's rename 500 functions and change parameter order for them") Something that does change the language or some interesting aspect of it (not: "I wish there was extension to support for XYZ protocol" or "I wish bug #12345 were finally fixed") Something that is more than a rant (not: "I wish PHP wouldn't suck so badly") Anybody has any good wishes? Mod edit: Stanislav Malyshev is a core PHP developer.

• HedgeWar code confusion

  - by BluFire

  I looked at an open source project(HedgeWars) that was built using many programming languages such as C++ and Java. While I was looking through the code, I couldn't help noticing that all the math and physics were gone from the Java code. HedgeWars I imported the project file called "SDL-android-project" which was a sub folder to "android build" and project files. My question is where is all the math and physics inside the code? Do I have to look at the C++ code in order to see it? I think Hedgewars was originally programmed in C++ but the files are confusing be because of its size and the fact that it has several programming languages inside.

• The practical cost of swapping effects

  - by sebf

  Hello, I use XNA for my projects and on those forums I sometimes see references to the fact that swapping an effect for a mesh has a relatively high cost, which surprises me as I thought to swap an effect was simply a case of copying the replacement shader program to the GPU along with appropriate parameters. I wondered if someone could explain exactly what is costly about this process? And put, if possible, 'relatively' into context? For example say I wanted to use a short shader to help with picking, I would: Change the effect on every object, calculting a unique color to identify it and providing it to the shader. Draw all the objects to a render target in memory. Get the color from the target and use it to look up the selected object. What portion of the total time taken to complete that process would be spent swapping the shaders? My instincts would say that rendering the scene again, no matter how simple the shader, would be an order of magnitude slower than any other part of the process so why all the concern over effects?

• How do you handle measuring Code Coverage in JavaScript

  - by Dancrumb

  In order to measure Code Coverage for JavaScript unit tests, one needs to instrument the code, run the tests and then perform post-processing. My concern is that, as a result, you are unit testing code that will never be run in production. Since JavaScript isn't compiled, what you test should be precisely what you execute. So here's my question, how do you handle this? One thought I had was to run Unit Testing on the production code and use that for my pass fail. I would then create a shadow of my production code, with instrumentation and run my unit tests again; this would give me my code coverage stats. Has anyone come across a method that is a little more graceful than this?

• Problems with EmusicJ on Ubuntu 14.04

  - by Michael Dykes

  I am running Ubuntu 14.04 in my new machine and have a subscription to emusic (because I used it before in my Windows days because of the great selection of classical music). I have used it on my old machine (running older versions of Ubuntu) with some success but am having difficulties doing so now. I am trying to use EmusicJ but do not/cannot remember how to do so. I have downloaded the program and unzipped it and ran the following command in a terminal: ./emusic If I remember correctly, once I go to the emusic site and download my music, the EmucisJ program should open and begin downloading the music through that program but this time it is not and I have already wiped my old box in order to give it to a friend. Any help is appreciated as I would like to continue with Emusic, but if I cannot get this resolved I will likely have to cancel my subscription and find a better alternative. Thanks.

• Dynamic tests with mstest and T4

  - by Victor Hurdugaci

  If you used mstest and NUnit you might be aware of the fact that the former doesn't support dynamic, data driven test cases. For example, the following scenario cannot be achieved with the out-of-box mstest: given a dataset, create distinct test cases for each entry in it, using a predefined generic test case. The best result that can be achieved using mstest is a single testcase that will iterate through the dataset. There is one disadvantage: if the test fails for one entry in the dataset, the whole test case fails. So, in order to overcome the previously mentioned limitation, I decided to create a text template that will generate the test cases for me. As an example, I will write some tests for an integer multiplication function that has 2 bugs in it: Read more >> [Cross post from victorhurdugaci.com]

• Webmaster Tools word count

  - by Henrik Erlandsson

  Is there a way to somehow verify that the googlebot finds the headings and the content, for example by word count? I'm asking this because I tried a program called Screaming Frog, which fails to even fetch the first h1 on a validated page - for about 1/3 of all the pages(!) - and got insecure. Even though the site looks hunky dory in Webmaster Tools, I'd like to know what a googlebot-like content crawler finds on my page and in what order. Any tips on such tools is appreciated. This is not about keyword count.

• What's the location of a personal 'gtkrc' file in Ubuntu 12.04?

  - by Kevin Perez

  Good day everyone! I am currently writting a software that makes easy to change default cursor theme with a few clicks. At this point it works well, but applications like Firefox or Lazarus IDE remain with the DMZ-White cursor, everything else is ok. I noticed that when I change the default cursor using my software, and later change the 'personalized' cursor theme using Ubuntu Tweak, it does the job, and the new theme is now applied everywhere. So, what file is need to modify in order to change 'personal' cursor theme? If my software can do this, that would be great! I found that 'gtkrc' is a file where settings of GTK+ are stored. I searched in my home folder but I can't find yet. Can you help me with this, noble people of Ubuntu? :)

• Loading content (meshes, textures, sounds) in the background

  - by Boreal

  In my game, I am aiming for a continuous world, that is, a world where you can go anywhere without breaking the immersion through load times and "virtual seams". My world is broken up into regions, which are nodes in a graph. A region is considered adjacent to another if it can be travelled to or seen from that region. In order to keep this continuous, I want to preload the assets needed in the adjacent regions (such as world meshes, textures, and music) before they are actually used. As for actually loading the content, I use a manager that keeps at most one copy of each asset in memory at a time, accessible by its filename. When I try to access an asset, it loads it (if necessary) and then returns it. I can then unload any asset that is currently loaded to save memory. Clearly, I want to do this in the background so there are no hiccups. I assume I have to use threads in some way, but I'm not sure how.
