  • Entity/Component based engine rendering separation from logic

    - by Denis Narushevich
    I noticed in Unity3D that each gameObject(entity) have its own renderer component, as far I understand, such component handle rendering logic. I wonder if it is a common practice in entity/component based engines, when single entity have renderer components and logic components such as position, behavior altogether in one box? Such approach sound odd to me, in my understanding entity itself belongs to logic part and shouldn't contain any render specific things inside. With such approach it is impossible to swap renderers, it would require to rewrite all that customized renderers. The way I would do it is, that entity would contain only logic specific components, like AI,transform,scripts plus reference to mesh, or sprite. Then some entity with Camera component would store all references to object that is visible to the camera. And in order to render all that stuff I would have to pass Camera reference to Renderer class and render all sprites,meshes of visible entities. Is such approach somehow wrong?

  • keybinding issues with xmodmap across synergy

    - by Rick
    I've got two systems I use across Synergy. On the main one I have a normal keyboard that I swap caps lock and ctrl for. So I do: xmodmap -e 'keycode 66 = Control_L' xmodmap -e 'clear lock' xmodmap -e 'add Control = Control_L' Where keycode 66 is my caps lock key. The trouble is that I can't get this key to act as a control key on the other machine I connect to with synergy. The strange thing is that if I plug a keyboard into the machine, and run xev, the control key there is keycode 37. When I then hit my modified control key (keycode 66 on the master) it's registering as keycode 37 on the remote machine. So according to xev, it should be picking it up as a control keypress. Anyone have any hints on if Synergy is doing something overly helpful for me?

  • Should I reorder partitions regarding performance

    - by Marcel
    I have in principal 3 big partitions on my Netbook. One Windows, one for shared files, one for Ubuntu. I recently find out (using hdparm) the the hardisk seems to have much better perfomance on the first 2/3 (~ 60MB/s) than on the last 1/3 (~ 40MB/s). I am thinking to delete the second partition and create new partitions for "swap" and / directly after Windows. Does this effort make sense? I also wanna upgrade to 10.4/10.10 but keep the option to go back to the old system, so maybe I install ubuntu completely in a/this new partition?

  • How can I improve overall system performance?

    - by Decio Lira
    What are your tips for improving overall system performance on ubuntu? Inspired by this question I realized that some default settings may be rather conservative on Ubuntu and that it's possible to tweak it with little or no risk if you wish to make it faster. This is not meant to be application specific (e.g. make firefox load pages faster), but system wide. Preferably 1 tip per answer, with enough detail for people to implement it. A couple of mine would be: Install Preload (via Software Center or sudo apt-get install preload); Change Swappiness value - "which controls the degree to which the kernel prefers to swap when it tries to free memory"; What are yours? PS: Since this is not intended to have a unique answer but rather, several useful tips, I'm making this community wiki out-of-the-box.

  • Graphics Driver problem, ATI Radeon HD 3200, small screen size and slows everything down.

    - by Arvind Jangid
    Regards. I am using a: 2009 Compaq Presario CQ40-415AU Notebook AMD Athlon X2 Dual core Processor 2.1 GHz 1024 MB L2 cache 3GB DDR2 RAM ATI Radeon + HD 3200 Graphics 256 MB, screen is 14 inch widescreen with resolution of 1280*800. I installed Ubuntu 12.04 LTS 32bit on my laptop. It works brilliantly until I installed graphics driver. When I installed the driver, the graphics became slow. Everything slowed down. Even the splash screen resolution changed to something like 640*480. I have liked Ubuntu since 9.10 and for the freedom it provides and its versatility, but graphics problem remains the same. I even installed Ubuntu on a 50 GB partition with 6 GB swap partition. My HDD is 320 GB. Please tell me what is wrong.

  • How do I list installed software with the installed size?

    - by Lewis Goddard
    I would like to have a list the installed software on my machine, with the disk space consumed by them alongside. I would prefer to be able to order by largest/smallest, but that is not a necessity. I am the sort of person who will install software to try it, and never clean up after myself. As a result, my 7GB (Windows and my Data are on separate partitions, as well as a swap area) Ubuntu 11.04 partition is suffering, and has started regularly showing warning messages. I have cleaned my browser cache, as well as everything under Package Cleaner in Ubuntu Tweak, and am left with 149.81 MB off free space.

  • *DX11, HLSL* - Colour as 4 floats or one UINT

    - by Paul
    With the DX11 pipeline, would it be much quicker for the vertex buffer to pass one single UINT with one byte per channel to the input assembler, as opposed to three floats? Then the vertex shader would convert the four bytes to four floats, which I guess is the required colour format for the pipeline. In this instance, colour accuracy isn't an issue. The vertex buffer would need to be updated many times per frame, so using a single UINT and saving 12 bytes for every vertex could well be worth it: quicker uploads to vram and also less memory used. But the cost is the extra shader work for every vertex to convert each 8 bits of the input UNIT into a float. Anyone have an idea if it might be worth doing? Or, is it possible for the pipeline to be set to just internally use a four-byte colour format? The swap chain buffer has been initialised as DXGI_FORMAT_R8G8B8A8_UNORM, so ultimately that's how the colour will be written. Thanks!

  • Ubuntu 13.10 software raid

    - by Piotr Belniak
    I had already Ubuntu OS installed on my desktop PC, where the software RAID 5 is configured ( 3 partitions /, swap and home ). This system was upgraded from the 11.04 till 13.04, it was quite messy, so I decided to install fresh system on existing partitions. 1st of all i found that there is no alternate version of the installer ( which i used to create previous installation ), so i stared with the regular image. I installed mdadm tools, assemble the partitions - fdisk are showing them properly - so i'm starting the installation - and everything i going fine until the GRUB instalation - this part fails - regardless of which partition i use as a target. From the other hand, neither OpenSUse and Ubuntu 12.04 alternate does not have any problems with installing the GRUB - on this configuration, unfortunatelly Ubuntu 12.04 - 12.10 upgrade is failing bacause of some Xorg issues ;(. Maybe someone has an experience with installation of ubuntu 13.10 GRUB on the RAID 5 partitions - and could give me a hint, how to solve my problem. Thanks in advance, Piotr

  • how to resize an encrypted logical volume?

    - by Nirmik
    I installed Ubuntu with encryption and LVM on my entire haddisk... Now I want to resize it. How do I do This... Following this link gave me errors on step 2 - How to resize a LVM partition? error ubuntu@ubuntu:~$ sudo e2fsck -f /dev/sda5 e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block e2fsck: Superblock invalid, trying backup blocks... e2fsck: Bad magic number in super-block while trying to open /dev/sda5 The superblock could not be read or does not describe a correct ext2 filesystem.

  • Best approach for a flexible layout for ASP.NET application

    - by Rohith Nair
    I am looking for a best approach for designing a dynamic page. I want my users to be able to determine the position of set of controls to be loaded into a page. Should be able to add new controls or swap in and out new controls into an existing page. Eg: Portal based applications,iGoogle kind of websites I am afraid that I will be re-inventing the wheel if I go and create a portal structure for my web application. There are a couple of things in my mind to look into: Good third-party suites which can do the same Should I look into Silverlight RIA application? I have researched about the Infragistics and Telerik controls and the price is high for just a control like LayoutManager which I need. Any alternatives? What is the best approach for this kind of situation, to add to the list?

  • text is not appearing at cursor in bash, can I reset it somehow?

    - by jcollum
    This happens sometimes if the VM bumps up against upper limits of memory and has to hit swap heavily for extended periods (a few minutes or more). When this happens and I type asdf at the prompt it looks like: $ No command 'asdf' found, did you mean: Command 'asdfg' from package 'aoeui' (universe) Command 'sadf' from package 'sysstat' (main) Command 'sdf' from package 'sdf' (universe) asdf: command not found $ Note that asdf isn't showing up after $. The obvious answer is to just kill the tab and start a new one. Still, I have to wonder if there's a way to reset a bash terminal that is misbehaving like this. I tried bash and it didn't make any difference.

  • Scripts won't affect clones - Unity3d

    - by user3666251
    I made a script which swaps two game objects on click.But the script won't work because the objects are actualy clones of the original prefab. This is the script (UnityScript): #pragma strict var object1 : GameObject; var object2 : GameObject; function OnMouseDown () { Instantiate(object2,object1.transform.position,object1.transform.rotation); Destroy(object1); } I use this script to create other game objects (clones)[c#] : using UnityEngine; using System.Collections; public class Spawner : MonoBehaviour { public GameObject[] obj; public float spawnMin = 1f; public float spawnMax = 2f; // Use this for initialization void Start () { Spawn (); } void Spawn() { Instantiate(obj[Random.Range(0, obj.GetLength(0))],transform.position, Quaternion.identity); Invoke ("Spawn", Random.Range (spawnMin, spawnMax)); } } The objects get renamed to NAME (Clone). What I wanna do is make the script affect clones too.So they will swap when I click on them.

  • How to change grub-bios to grub-efi

    - by user92325
    So a while ago i installed Ubuntu on my Macbook. I had to reinstall it because something in the update manager messed up. Not to concerded about that but for some reason after the installation Ubuntu wont boot. I found out later that Apple hardware uses EFI as the BIOS. Every time i try to install it i make a swap space and the root file to make the installation. I noticed that when i make the boot file its in grub-bios. I need to change this to grub-efi i found out but theres no option to change this. It still wont boot though. When i install it i dont get any errors but doing a little bit of reasearch i find that the boot file may be the problem im not entirely sure how to fix this but if anyone could give me some insight on this subject id very much appreciate it

  • After re-installing ubuntu 13.10, stuck at GRUB Rescue, Boot-Repair didn't work!

    - by user205691
    Because i could not get the WiFi login work, i thought i will reinstall ubuntu, with internet connection to have updated drivers for wireless & graphics etc. I have deleted earlier linux partitions usings gparted and re-installed ubuntu 13.10, exactly following the same steps as i did earlier, making a 100GB /home on dev/sda and pointing root to /dev/sdb (SSD) and swap on dev/sda/ . Installing boot on /dev/sdb. But, somehow i think the grub is either corrupted or removed because i am unable to boot the laptop to any OS now. I get the following message: "no such device" xxxxx followed by huge HEX number GRUB rescue when i type ls on Grub rescue prompt, i can see hd0 & hd1, but thats about it. i tried Boot-repair but it is unable to fix the problem. The following log is generated via boot-repair create log: Boot-repair log I am unable to boot into windows or linux at the moment and need help to fix the grub so i can boot !!

  • Ubuntu on Mac mini and refit

    - by Thomas
    I have successfully installed Ubuntu pangolin 64 bit on a mac mini 2011 5,3 ( server version ). I have used the Ubuntu iso which I then converted to .dmg and dd'ed into an usb stick. I didn't want to keep OS X installed so I deleted the current partition and reformatted the drive as ext4 for / + a small swap partition. Everything seems to work nicely, but I have now a question since I read lots of reviews/howto when you people installed rEfit on Mac OS X. Did you use rEfit to be able to have a dual boot or there are other advantages by doing that ( apart that you will be able to download updated firmware for your hardware in the future via Mac OS ) like BIOS emulation and the like ?

  • No root file system - Alternate CD + LVM

    I am trying to install 11.10 as dual boot with Windows 7. I have all partitioned well as you can see here: http://www.flickr.com/photos/42897978@N00/7111180385/ I burned the Alternate CD ISO to a CD. Boot from it and followed instructions to Partitioning. There, I configured the LVM partitions as follows: Volume Group ubuntu-vg - Uses Physical Volume /dev/sda7 380GB - Provides Logical Volume home-lv 60GB - Provides Logical Volume root-lv 60GB - Provides Logical Volume swap-lv 6GB That is all I want (note that my /boot is outside of LVM) Then when I say that all is Ok and to write it to disk and continue with the installation, I get the following error. !! Partition Disks No root file system No root file system is defined Please correct this from the partitioning menu. What should I fix and how? I tried issuing the "Revert changes to partitions", but nothing happens. It seems that the LVM configuration has already been written to the CD. HELP!!
