• How to delete all your old website data from the internet?

  - by Akky Awesøme

  I had my website on rohbits.com but for some reasons I had to delete it and recreate it with this URL wwww.rohbits.com/blog. My problem is that the old links are still visible on google search and when people click on those links, they land on a 404 Error page of the hosting company. I want to either delete all the previous data from the search engines or have an 404 Error page of my own so that I can tell my visitors where the actual website is. I have already redirected all the traffic which comes to rohbits.com to www.rohbits.com/blog but when they click on the expired links, they get this error page. One sample expired link is this one: http://rohbits.com/wordpress-tricks.

• Can there be an Environment that Reacts to Weather changes in-game?

  - by The415

  Just to be straightforward, I am completely new to many aspects of coding and am searching for different specs and guidelines to aid me on my journey to crafting a wonderful game in Epic Games' Unreal Engine 4. I had some recent thoughts about the possibility of creating an environment in a game that interacts with weather (Rain, Snow, Storms) Is it possible to make an environment that can simulate weather changes in a game? I wrote notes on this for weeks now. I was thinking that an increase on environments occlusion maps was necessary for creating the effect of rain on windows, as well as making a flowing liquid surface on windows that is only visible in rain. I was also considering the idea of additive bump-maps on meshes for snow, to simulate accumulation. Are these elements dynamic in Unreal 4? Can I implement them?

• How can I support scrolling when using batched rendering for my tiles?

  - by dardanel

  I have tiled map 100*75 and tiles are 32*32 pixel.I want to use batching for performance .I don't figure it out , because of my game needs scrolling and every frame i draw 22*16 tiles (my screen is 20*16 tile) .I thought that batching tiles for every frame .Is it good or any suggestion? edit :to more clarify I want to use occlusion culling and batching at the same time.I thought that drawing only visible areas and batching them together .But there is a something i couldn't figure out .When scrolling screen with translate matrix , if one row become invisible , I bind new row and batch them again.Every batched objects needs to buffer again.So I batch tiles and buffer to VBO every time when one row become invisible .I don't know these way is efficient or not .This is my question .And i am open to any suggestions.

• Javascript slider with fade

  - by tarmes

  I've been scouring the web for a slider that offers a particular effect, but I can't find one. I'm hoping that someone here will be able to help out... Specifically, I need a slider that will slide left and right through a series of HTML DIVs. However, I also need the old slide to fade out as it slides. This is because I don't what to have a visible frame around the the slider, so I don't want the old slide to be cropped against an invisible edge. It's hard to explain in words, so here's a graphic. In each case the green slide is entering the view, the red one is existing. Is possible, I'd like the slide to use CSS3 transitions where available for the smoothest possible effect. Has only ever come across such a beast?

• How do I draw a texture to a MSTerrain object?

  - by Brad

  I'm using Farseer to make a game in XNA and I can't seem to figure this out. I've decided to use MSTerrain for making my game's terrain because I wanted destructible terrain and MSTerrain seemed like the best bet. Unfortunately, I'm stumped on how to actually show the terrain. When I generate the terrain it's visible in debug view, but MSTerrain does not have a Draw method, so I'm wondering how it is supposed to be drawn to the screen? Is it worth pursuing? I'm starting to think that MSTerrain is more trouble than it's worth, is there another better way to do this with bodies?

• How to use a mask texture with Kobold2D

  - by alex

  I am an iOS developer but I'm new to cocos2d. I'm working on new game, I use Kobold2D, have cocos2d installed too, and I want to make this effect: I know how is done with Flash, but can't make it with Kobold2D. There's 2 images with the same size: one is a low-res image for the background and the second is a hi-res over the first one. When the "reticle" mask moves, it reveals the second image inside the circle and the background is visible outside only. I googled with no success, saw some Ray Wenderlich projects they weren't helpful.

• How to hide keyboard layout shortcut from Unity top panel?

  - by user67715

  I'm using Ubuntu 12.04 together with X Neural Switcher, which is a program for the automatic switching of the keyboard layout. The switcher goes with a GUI called gXNeur. The GUI places an applet icon to the Unity top panel (the gXNeur had to be whitelisted for the icon to become visible) that help a lot to configure and make urgent changes in the rules that the program uses. But after the icon is whitelisted I'm having two keyboard layout indicators in the panel (one - native, the second one - gXNeur). The native is the one I'd like to hide while gxNeur is more intuitive. Is there a way to do that? Thanks a lot for your help!

• How can I set up private, per-user sections on Joomla?

  - by Michael Paulukonis

  For this weekend's GiveCamp project, my team has been tasked with adding some functionality to an existing Joomla-powered website for a non-profit. A certain type of user will login, and have access to a personal area where they can upload files, check for messages, see tasks that have been assigned, etc. Each user would have their own area. They would not be creating pages, and their information would only be visible to themselves (or a site-administrator, of course. No sort of weird HIPAA privacy involved). None of us have worked with Joomla before, but we'd like to help this non-profit. We're not sure if we're searching using the wrong terms, or if we're just not finding it. Is such a solution possible in Joomla? And/or are we better off building some standalone solution that interfaces with the same mySQL database as Joomla?

• Ubuntu 12.04 External HD Issues

  - by Anthie Georgiadi

  I am experiencing one more problem with my Ubuntu 12.04... I have an External HD (500GB) which is NTFS formatted. I connected this HD on my Ubuntu 12.04 and copied some files. When I connected the HD on a Windows 7 machine I could find the folders (the were visible) but I wasn't able to copy/cut/delete them. However when I opened the folders I could handle the material (mp3s) in them. Does anybody know how can I fix this? How can I fully access and modify folders copied from Ubuntu via a Windows machine? Thanks in advance!

• Trouble with Libreoffice 4.0.* in Ubuntu 12.04

  - by isotoper

  I have used Libreoffice Impress to give presentations at meetings for some time now. The current version of Libreoffice in Ubuntu 12.04 is 3.5.7.2 and this works fine for me. Recently, following a recommendation from a colleague, I installed Libreoffice 4.0.something using the Libreoffice PPA. This worked, but I discovered when going into slide show mode most of the graphics (line graphs) disappeared, even though they were perfectly visible in the original. Lettering, drawings, and pictures came over, but not the line graphs (which were originally inserted in .eps format most likely). With some effort I managed to uninstall the more recent version of Libreoffice, and reinstall the version in the Ubuntu repositories (3.5.7.2) and the graphs now appear as expected in the slide show mode. Is there any explanation for this behaviour?

• frequency out of range - please change display mode

  - by Dave

  I just downloaded the latest version of the Ubuntu live CD, and have installed it on a desktop computer (a Fujitsu Scaleo P). Once installed it seems to work perfectly, although there are some updates recommended in the Update Manager. My problem is that, after having installed these updates and restarted the computer, I get this message on my monitor, and no Ubuntu interface is visible: frequency out of range - please change display mode I do not know how to change this when I can't access an interface. Is there a command that will bypass trying to boot the GUI and let me change the display mode via a CLI? I am brand new to Ubuntu and any help on this would be much appreciated.

• Android Dynamic 2D Map

  - by Deltharis

  My problem is, I want to create a 2D tiled map. Yes, I know it's been asked a lot. I've seen answers that propose the use of tiled however it only allows (or so it seems to me) to generate static maps that do not change once generated. And I need a large empty uniform space of empty tiles, upon which players may place various buildings (some spanning more than one tile and logically being the same one). How to approach this in Android? Do I make some kind of TableLayout, use arbitrarly large amount of rows and imageviews (with my emptyTile), than somehow work event-based changing of image ids from there? I'd think that only a portion of that map should be visible at a time, but I don't see how scrolling around could be the part of that structure.

• Scrolling background with changing textures

  - by Simran kaur

  I have the 2 cubic structures that are my tracks and are scrolling basically to give effect of movement on object. In my OnBecameInvisible() method, I have changed their Tiling using mainTextureScale void OnBecameInvisible() { renderer.material.mainTextureScale = new Vector2(1, numberOfLanes); this.transform.position = new Vector3(this.transform.position.x, this.transform.position.y, 20.0f); } The tiling works fine. But the alternative tracks have their Tiling set to 0 which is giving an undesirable effect. Requirement: I want to be able to set the Tiling of every track that is visible on the screen. How do I do it?

• XNA Octree with batching

  - by Alex

  I'm integrating batching in my engine. However I'm using an octree which is auto generated around my scene. Now batching renders a hole group at ones while an octree sorts out which objects that should be rendered within the camera frustum, therefore dividing the group. Batching and octree doesn't go along very well, right? Problem: The way I see it I have two options, either create batch groups based on objects who are close to one another within the octree or I can rebuild the batching matrixbuffer for the instances visible each frame. Which approach should I go with or does there exist another solution?

• Can I use metro style interface in my own web application?

  - by LukeP

  I am wondering if I would need to license the Metro style or if I can just freely use it in my own applications. I mean, is it patented or protected in any way that would prevent me from building my own implementation? I effectively would like to copy the visible part of it. I like to idea of being able to: Provide an interface which is used somewhere else (as in 1 less to learn) Use the interface that has been tested for usability (I personally like it) Have the possibility of getting free publicity because of implementing full Metro style web application while not associated with Microsoft, etc.

• Enable permanent vertical and horizontal scroll bars

  - by Rolen Koh

  I am facing a problem and it is in Ubuntu (14.04) permanent scroll bar is not there but it appears when you move the mouse pointer to right most side or bottom most side. But it is very difficult to use and lately it takes too much to appear and sometimes it doesn't appear at all and so i have to close the application and reopen it. So i want to ask how to enable permanent scroll bars on right side and bottom most side. I am sure many people must have faced this problem before me. Thanks. P.S: By permanent i mean scroll bars should be visible all the time.

• Macro vs. Static functions in Header

  - by wirrbel

  for a lot of quick tasks where one could employ a function f(x,y), in plain C, macros are used. I would like to ask specifically about these cases, that are solvable by a function call (i.e. macros used for inlining functions, not for code expansion of arbitrary code). Typically C functions are not inlined since they might be linked to from other C files. However, static C functions are only visible from within the C file they are defined in. Therefore they can be inlined by compilers. I have heard that a lot of macros should be replaced by turning them into static functions, because this produces safer code. Are there cases where this is a not good idea? Again: Not asking about Code-Production macros with ## alike constructs that cannot at all be expressed as a function.

• Installed Ubuntu 14.04. How do I get it working with my new AMD R9 280X. When I run it I get garbage on the display

  - by user289455

  I installed Ubuntu 14.04 on my Gigabyte A88X FM2+ motherboard and A10 7700K processor. Everything worked perfectly. This system is dual booted with Windows 8.1 for gaming and I installed subsequently I installed an AMD r9 280X gpu. Windows was easy. It kept working with the new card installed and I just needed to download and instal the driver. Reboot and it's done. Ubuntu boots into a blank display. I enter the password and can log in. The menu on the left and bar at the top are visible but when I try to open an app, I get blocks and rubbish on the display. My preference is not to remove the card. So, my question is: What would be the procedure I could follow where I can log in using a text based terminal and download and install the AMD drivers.

• Bluetooth issues after Saucy upgrade

  - by charlie

  I upgraded from Raring to Saucy, and now my bluetooth is giving me problems. First, even though I have a bluetooth inbuilt in my laptop, which I prefer to keep off unless I am using it, there is no greyed out bluetooth icon in the notification area. This was present in Quantal, but was missing in Raring too. I was hoping to get this fixed in Saucy. Seems otherwise. Secondly, and more importantly, in saucy when I am turning on my bluetooth, it immediately (or within seconds) turns off automatically, without giving me any time to even make the device visible. Please help!
