• Older PHP v/s newer PHP version [closed]

  - by Monty

  My company is building a website with database. Programmer's used PHP 5.0. My Service Provider (shared) in the meantime upgraded to PHP 5.3.0. Fixes have been on going and seem endless... Do I move to VPS and install older PHP or should we rebuild with newer PHP? When working remotely with programers what is the protocol regarding delivery of all code? Please what is the industry standard? I need an independent to review their work. How should this be approached?

• Upgrading a dual-boot system HDD

  - by Jason

  I dual-boot my laptop due to lousy VM performance, and have a new 500GB/7200rpm drive coming in to replace the stock 320GB/5400rpm drive. I have the drive set up in three partitions: one for the Win7 system files, one for storage, and the third as the ext4 Linux file system. The system file and storage partitions are both NTFS. What I'm planning to do is use the system image creator built in Win7, then move that over to the new drive. However, how can I migrate the Ubuntu partition, and how do I make sure that the Grub bootloader isn't overwritten by the Windows loader?

• how to read the password from variable?

  - by Viswa

  I am trying to move my file to another system which is located in some other place, with this command: rsync -avrz src destination It works fine. But what I need is to put this command in shell script and run it like: #! /bin/sh rsync -avrz srcfilelocation destination When it runs, it asks for the destination system password. I know that password and give it manually. Now I have decided to assign the password to an environment variable, like pswd="destination system password". I need my shell script to read the password from this variable. How can I write a script to do this?

• How to remove unused usings from class file ?

  - by Samir R. Bhogayta

  When we create a .cs file means code file class is automatically create. That .cs file means class has default usings for namespace. using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls; We don't use all namespaces  in that class so we have to remove unused namespaces from file. We can remove  namespace manually but it takes time and need full knowledge of class library so we can use Visual Studio . Step 1:  Right Click in .cs File. Step 2:  Move on Organize usings. Step 3: Click on Remove Unused Usings. After that we have only those namespaces in the file these are using.

• Resuming from hibernation shows a fuzzy "static" screen

  - by Ross

  When I resume from hibernation in Ubuntu 10.10 the screen shows static, very similar to what you see on an analogue TV that hasn't been tuned properly. This also occurs on boot from shut down, but only for a moment after the Plymouth boot screen. The static lasts for at least 5 minutes. An odd thing that happens is that the mouse pointer, as a lighter square of static, becomes visible and you can move it around. Attempting to change into a terminal (i.e. Ctrl+Alt+F1) doesn't seem to work (and I'm not sure if that can be done from the login screen). Resuming from suspend has different issues - vertical lines appearing for a second before appearing to be in terminal mode (blinking cursor) and then going to the lock screen. I'm running Ubuntu 10.10 on a Dell Studio 15 with ATI graphics, however I'm not using the proprietary drivers as I had issues with dual-screen support, so it's the generic X.org drivers being used.

• Edge flicker when moving Camera (2D)

  - by Matthias Reisner

  I have a Orthographic camera. I have a fixed landscape texture and a texture for a moveable object. If the object moves to the right the camera will also move with the object. When I also draw an score text that should have fixed position on the screen, that score text position will be update too if the camera's position gets updated so that it looks like that it is fixed on the screen. But if I do that, I have some edge flickering at the text object. I'am using SpriteBatch! Is there another approach to implement a fixed positioned object on the screen?

• How do I temporarily reference a new web host using my existing domain name?

  - by Alex Angas

  On provider A I have an existing web hosting account running my site. On provider B I have my domain name registered pointing to the web hosting on provider A. I've just purchased a web hosting account with provider B and want to move my site there. Is there a way to temporarily use my domain name to point to provider B while I set up the site (e.g. just from my computer)? I tried to change the HOSTS file (Windows) and while pings resolved to what I set, HTTP requests don't.

• Level Representation in a 2D Game

  - by meszar.imola

  I would like to create a 2D game, where a character should move on a stage/level. My stage would be static, constructed some little cubes, similar to the well-known Mario game: some of the elements should represent an element of the way where the character can step, but if the element is missing, the character should fall. My problem is, how to represent this programmatically? My first thought was to represent the stage with a vector, which should contain boolean elements, depending on the state of the element on the stage - if it's missing or not. But this means, I have to verify at my character's x or y position change if it has a stage element under or not (if not, to simulate the falling of the character) - I think it is not the best practice, it's not the beautiful solution. Can you help me with some advice, how to represent the stage?

• Photo and Video backup [closed]

  - by MyNameIsTooCommon

  Apologies if this is the wrong forum. Please move if necessary I want to back up all my photos and videos online. Some videos are HD and up to 2GB in size. Does anyone know of any good sites? Flcker and Picasca seem the obvious ones but there seem to be limits on size. I have also heard bad things about the Picasca UI. I basically want to remove most of the photos from my laptop HD and then sync with web when I want to download them. Viewing via mobile is not a big thing for me. I just want somewhere save to back up stuff. Thanks

• How can I imitate interaction and movement in Diablo II?

  - by user422318

  I'm prototyping a simple browser-based game. It's played from a top down perspective on a 2d canvas. You left-click on a point on the map, and your character will begin walking to it. If you click on a different point on the map, then your character will begin walking to the new point. It's similar to Diablo II: http://www.youtube.com/watch?v=EvDKt-To6K0&feature=related How can I best imitate this movement system for a player? Ideas... Track current coords and target coords If target coords are exactly up, left, right, or down, then increment appropriate direction until you get there Implied else: target coords are in a quadrant. To make this movement look natural, character will have to move diagonally. For example, pretend the target is to the northeast. For each game frame, alternate incrementing current coordinates in the north and then east directions.

• Hidden Launch Bar wouldn't slide-out when moused over, now it won't hide away.

  - by Dave Keller

  When the launch bar is hidden, I have trouble getting it to slide out when I move the mouse pointer to the left side. After adjusting the settings under Settings--Appearance--Behavior, the bar no longer hides when a browser is open. Is there a fix for this. This all happened when I was looking for a way to change the icon sizes in the launch bar. Documentation from Linux.com told me to do it under Settings--Appearance, but there was no way to do it. Any help is appreciated! Thanks.

• How do I un-zoom compiz?

  - by Ken

  I'm using a keyboard I'm not used to, and I hit Super_L instead of Alt_L when I middle-mouse-dragged across the screen. On this Ubuntu 10.04 with Compiz, apparently, this zooms the screen to the area that I dragged across. Now I'm stuck. I can super-middle-drag across a bigger area, but apparently I can't quite hit all of the corners exactly because the screen still moves a bit when I move the mouse around. How do I undo this zoom effect completely? This looks like "EZoom", which says that super-"1" (default keybinding, anyway) should reset it, but that doesn't seem to work here. Close...

• Translate along local axis

  - by Aaron

  I have an object with a position matrix and a rotation matrix (derived from a quaternion, but I digress). I'm able to translate this object along world-relative vectors, but I'm trying to figure out how to translate it along local-relative vectors. So if the object is tilted 45 degrees around its Z-axis the vector (1, 0, 0) would make it move to the upper right. For world-space translations I simply turn the movement vector into a matrix and multiply it by the position matrix: position_mat = translation_mat * position_mat. For local-space translations I'd think I'd have to use the rotation matrix into that formula, but I see the object spin around instead when I apply a translation over time no matter where I multiply the rotation matrix.

• Maya is lagging in a specific way...?

  - by Aerovistae

  My Maya installation worked perfectly. It is not my computer. Something caused it to stop working overnight, somehow. When I try to drag a vertex or something like that, it moves the vertex, but then I have to click like 3 times somewhere outside the mesh before the actual mesh will catch up and follow the vertex. Until I do that, it just stays as it was, with a floating vertex somewhere inside it or outside it. It makes modeling borderline impossible and completely infuriating. What ought to be happening is what we're all used to-- as I move the vertex, the mesh follows it actively, so I can see what it looks like at every given moment until I release the vertex in its new position. Other weird thing: this only applies to complex meshes, like a couple thousand faces. A simple cube works fine. What gives?? Anybody?

• Problems running Ubuntu 12.10 in VMWare Player 5

  - by Tiim

  I'm trying to install Ubuntu 12.10 in VMWare Player 5. My pc is running Windows 7. The installation seems to go okay, but when I boot up ubuntu, although it starts up and I see the desktop, I can't see any task bar or basically anything other than the default wallpaper in the background. When I move my cursor across the screen towards the edges, the desktop flickers and extremely distorted and pixelated objects appear momentarily. I've tried uninstalling everything, downloading it all again and reinstalling, but I get the exact same problem. Does anyone recognise this issue? Is there a more stable pairing than Ubuntu 12.10 & WMWare Player 5.0.1, perhaps?

  Let's see if someone can help me with two mini-bugs I have: Sometimes, when I close the laptop and later open it, the touchpad stops working properly.

Whenever I turn on the computer, some keys excange with others (" becomes @, ? becomes _, ¿ becomes +, etc), and I have to go to Keyboard input and add and delete some language (I use Afgan because it's the first) Thanks.

• Disqus thread migration. Gotchas?

  - by sramsay

  I've been migrating a site to a new domain. The site itself is pretty straightforward (it uses Jekyll), and everything has gone fine -- except migration of Disqus threads. I've had partial success -- some of the threads have migrated successfully, but not all. I've tried the domain migration wizard (which caught a few), the URL mapper (which caught a few), and the 301 redirect crawler (which caught a few). But the remaining threads just won't move, no matter which method I use. So, I suppose I suppose I'm asking if there are any "gotchas" I should know about with this. When you execute any of these migration tools, it says it will "take awhile." Does that mean hours? Days? I can't tell if it's working, and there's no logging or error reporting that I can see.

• Ubuntu 14.04 + nvidia-331-updates makes a blank desktop screen

  - by Achint

  I upgraded my installation from 13.10 to 14.04. The problem is that whenever I install the Nvidia drivers from the GUI, upon reboot or trying to login again it only shows the wallpaper of my desktop and nothing else. The mouse does move around, but nothing works. I am unable to open a terminal or do anything else. If I go into the tty console and purge the drivers, then things seem to work again. I have an Optimus setup, with an onboard Intel and discrete Nvidia GTX770M card. It's a 64-bit architecture. I really need to work with CUDA, and was hopeful after hearing that nvidia-prime was released, but this is a real downer. Any help on this?

• Deferent ways of solving problems in code.

  - by Erin

  I now program in C# for a living but before that I programmed in python for 5 years. I have found that I write C# very that most examples I see on the web. Rather then writing things like: foreach (string bar in foo) { //bar has something doen to it here } I write code that looks like this. foo.ForEach( c => c.someActionhere() ) Or var result = foo.Select( c => { //Some code here to transform the item. }).ToList(); I think my using code like above came form my love of map and reduce in python while not exactly the same thing the concepts are close. Now it's time for my question. What concepts do you take and move with you from language to language. That allow you to solve a problem in a way that is not the normal accepted solution in that language?

• Synchronise graphics and logic code

  - by Skeith

  I have a procedural approach to the game loop that runs various classes. it looks like this: continue any in progress animations check for used input apply AI move things resolve events such as collisions draw it all to screen I have seen a lot of posts about how drawing should be running separately as fast as it can, possibly in another thread. My problem is that if the drawing runs as fast as it, can what happens if it tried to draw while I'm still applying the AI or resolving a collision? It could draw the wrong thing on screen. This seems to be a well established idea so there must be an explanation to this problem as I just cant get my head around it. The only solution I have is to update the screen so fast that any errors like that get refreshed before we see them but that sounds hacky. So how does this work / how would you implement it so that they are in sync but running at different speeds?

• Adding an existing Control Domain to a Server Pool

  - by Owen Allen

  I got a question about LDoms: "Is it possible to move a Control Domain built through Ops Center with pre-existing LDoms into a server pool? If so, do I need to delete and recreate anything?" Yes, you can do this. You have to stop the LDom guests, and then you can add the CDom to a Server Pool. If the guests are using shared storage, you should be able to bring them up in the Server Pool. If the guests are not on shared storage, you can use the Migrate Storage option to bring their storage in.

  - by Diken

  Hey i have issue regarding jump sprite body. In my code i am using moveLeft and moveRight Button and when i am press moveRight Button using following code if (moveRight.active==YES) { b2Vec2 force=b2Vec2(4,0); ballBody->SetLinearVelocity(force); } Its move perfectly and When i release this Button than sprite body stop using following code else { b2Vec2 force=b2Vec2(0,0); ballBody->SetLinearVelocity(force); } But when i put this else part then jump can not done. My jump code is following if (jumpSprite.active==YES) { NSLog(@"Jump Sprite"); b2Vec2 locationWorld; locationWorld=b2Vec2(0.0f,4.0f); double force=ballBody->GetMass(); ballBody->ApplyLinearImpulse(force*locationWorld, ballBody->GetWorldCenter()); } If i remove else part then jump will perform complete but sprite body can not stop after release button. So what to do?? Thanks in advance

• google maps based desktop application

  - by dramaticlook

  I want to build a desktop application which has google maps embedded to it. This app should have a thread to read coordinate data online a usb microphone to use. This application will move the google map markers to their new locations based on the data retrieved from online connections on each refresh. As far as I know gmaps has a javascript API so the first idea in my mind was to embed this mapview into a java applet. So the application will run on a browser. Im not sure if this will work. Do you guys have any idea about this or any other advices you might have? Thanks in advance!!!
