  • Why are MVC & TDD not employed more in game architecture?

    - by secoif
    I will preface this by saying I haven't looked a huge amount of game source, nor built much in the way of games. But coming from trying to employ 'enterprise' coding practices in web apps, looking at game source code seriously hurts my head: "What is this view logic doing in with business logic? this needs refactoring... so does this, refactor, refactorrr" This worries me as I'm about to start a game project, and I'm not sure whether trying to mvc/tdd the dev process is going to hinder us or help us, as I don't see many game examples that use this or much push for better architectural practices it in the community. The following is an extract from a great article on prototyping games, though to me it seemed exactly the attitude many game devs seem to use when writing production game code: Mistake #4: Building a system, not a game ...if you ever find yourself working on something that isn’t directly moving your forward, stop right there. As programmers, we have a tendency to try to generalize our code, and make it elegant and be able to handle every situation. We find that an itch terribly hard not scratch, but we need to learn how. It took me many years to realize that it’s not about the code, it’s about the game you ship in the end. Don’t write an elegant game component system, skip the editor completely and hardwire the state in code, avoid the data-driven, self-parsing, XML craziness, and just code the damned thing. ... Just get stuff on the screen as quickly as you can. And don’t ever, ever, use the argument “if we take some extra time and do this the right way, we can reuse it in the game”. EVER. is it because games are (mostly) visually oriented so it makes sense that the code will be weighted heavily in the view, thus any benefits from moving stuff out to models/controllers, is fairly minimal, so why bother? I've heard the argument that MVC introduces a performance overhead, but this seems to me to be a premature optimisation, and that there'd more important performance issues to tackle before you worry about MVC overheads (eg render pipeline, AI algorithms, datastructure traversal, etc). Same thing regarding TDD. It's not often I see games employing test cases, but perhaps this is due to the design issues above (mixed view/business) and the fact that it's difficult to test visual components, or components that rely on probablistic results (eg operate within physics simulations). Perhaps I'm just looking at the wrong source code, but why do we not see more of these 'enterprise' practices employed in game design? Are games really so different in their requirements, or is a people/culture issue (ie game devs come from a different background and thus have different coding habits)?

  • Ubuntu 12.04 keeps rebooting after changing video settings

    - by ScottJShea
    In a pinch I had to install Ubuntu 12.04 on an HP Pavilion g6. I was not fond of the 1024 x 7678 resolution so after investigating and finding I had the intel chipset I set the below in the grub file: GRUB_GFXMODE=1366x768x32 GRUB_GFXPAYLOAD_LINUX=1366x768x32 This did not work. The system just keeps rebooting as nauseum. I powered down, inserted my Ubuntu Install USB, powered up, edited the Grub file on the disk (made sure it was the disk and not the Grub for the USB stick). Powered off and tried booting up again. Same thing. So: As a noob am I missing something in the boot to allow me into a recovery mode? (I cannot seem to get to the Grub menu) If not is there a way I can recover from this? UPDATE: Holding down the shift key after BIOS gets "GRUB Loading..." and then a reboot

  • Ubuntu 13.10 - Black screen after logging in after installing nVidia drivers

    - by Javacow
    I recently installed Ubuntu 13.10 in a dual-boot with Windows 7, so I'm still quite new to using Linux. Most things were working fine, and I could log in normally (apart from the first login after install, which spent about 2 minutes on a black screen before going to the desktop). I installed the restricted Nvidia drivers with the command: sudo apt-get install nvidia-current Since then, after I enter my password and log in (the login screen itself works perfectly), I get a black screen with the cursor and nothing happens from that point onwards. Basically, what I would like to know is how to get back to the normal Ubuntu desktop and (hopefully) still be able to use Nvidia drivers.

  • How to reinstall latest Ubuntu Touch on Nexus 4?

    - by Galen Gruman
    I've followed the instructions on https://wiki.ubuntu.com/Touch/Install, first doing the steps that lead to phablet-flash -b and then the manual ones. In both cases, I get stuck at the Google boot screen. It does not boot into Touch. No errors during manual install, and adb devices shows the device, but I get the following with phablet-flash or phablet-flash -b (second and subsequent times, not the first time): Device detected as /system/bin/sh: getprop: not found Unsupported device, autodetect fails device When working on flipped images, detection does not work and would require -d Not clear what that all means. The Nexus 4 had the initial Touch dev preview on it, FYI. I saw no separate instructions for upgrading from that.

  • How do I turn off all the password prompts?

    - by Barkerto
    I've been using Ubuntu 12.04 LTS since release and am trying to figure out a couple things about all of these passwords and key-ring prompts that I've just been living with for a while. Ever since install it seems that every time I boot up my computer and want to do anything (ie. use the internet, use a internet browser, install something, delete something, pick my nose) I'm always prompted for either a normal password entry or a key-ring password entry. Is there anyway to turn off all of this "security" and tell my Ubuntu that it can trust what I'm doing and go take a shower? Thank You in advance, barkerto

  • 3.5.0-18 kernel update broke BCM43228

    - by ignition
    After updating the kernel to 3.5.0-18 the Broadcom BCM43228 wireless card of my Acer Aspire One 756 has stopped working properly. The card often refuses to connect to my AP, and if it connects it behaves very unstable. I have already reinstalled the drivers, as recommended by googling around. As far as I can tell the only driver that supports my card is the bcmwl package. I found one solution saying I should install broadcom-sta using module assistant, however I could not get this to install and apparently broadcom-sta and bcmwl are effectively the same driver? Is anyone experiencing similar issues? Is it possible to just downgrade to the previous kernel version?

  • How to access localhost remotely - Wordpress?

    - by Marcappuccino
    I have installed a LAMP stack (sudo tasksel install lamp-server) and wordpress (sudo apt-get install wordpress), but now, I would like to access my server remotely, to be used as a home fileserver. For example, my public ip is 82.16.xxx.xxx. Opening it in firefox with the suffix :8080 brings up my router config page..? Do I have to set up port forwarding? BTW. Accessing via localhost/wordpress/ works fine, I would just like to access my files while away from home.

  • HELP: I Broke Ubuntu By Uninstalling Compiz

    - by tSquirrel
    I'm still getting used to Linux, having come from Windows. I was receiving an error that "compiz" had crashed a few times so I figured I'd uninstall it. sudo apt-get remove compiz sudo apt-get install compiz I logged out then back in, after that, the GUI was totally gone and I have no idea how to get it back or what I need to do to restore the GUI to what it was before I killed poor Compiz. GUI was pretty much unmodified after a fresh install of 14.04 How can I fix it? I'm not even sure how to get to a terminal or anything. The login screen looks normal, but after logging in, it's a totally bare desktop with my backround and a few icons. No Dash, toolbar, etc. Hot Keys don't seem to work either (Super = Dash doesn't work, etc); although I did accidently open "Disk" UI. Not sure how. Please Help! Right now I'm working off my W7 dualboot.

    I'm trying to update from ubuntu 12.10 lately but I keep getting the "Failed to fetch" error.

  • Windows 7 won't boot

    - by Johnny
    I installed Ubuntu from my live CD and chose to install it alongside Windows. Yesterday, everything worked just fine and I was able to boot from either OS. However today, only Ubuntu will boot and Windows 7 fails to start every time I attempt to (even after restoring my Windows 7 partition to the last known good date). What could have changed over night that caused this? I did install all the recommended updates for Ubuntu. Is my only option going to be to wipe my HDD and reinstall both Windows and Ubuntu?

  • After reinstalling ATI graphics drivers, my keyboard and mouse aren't working anymore

    - by Lifelike27
    On Ubuntu 11.04 I tried to install the open source drivers for my laptops ATI Mobility Radeon 5470M but I messed that up a bit and lost xserver. Now I've managed to solve that problem with this and by downloading the ATI proprietary drivers and install those manually. Now, when Ubuntu loads up I get to the login screen but I can't use my mouse or my keyboard (usb keyboard and mouse doesn't work either). If I use the recovery console, then login with that and then run 'startx'. I can login fine (though Unity doesn't show, the graphics seem to be working because it shows the fading animation of libnotify), but I can't type or move my mouse.

  • Getting wireless to work on Ubuntu 11.10 (on a mac machine)

    - by yayu
    I have a 2008 white 13.3 inch macbook that now solely runs ubuntu. However, I cannot get wifi or cable to work on it. Regarding the cable, it atleast tries to connect but eventually disconnects from the wired network. Here is the output for lspci (pastebin) I tried installing b43-fwcutter and firmware-b43 but get errors. (I loaded them from a thumb drive and tried sudo dpkg -i). I cannot understand these instructions from the documentation, as I cannot locate the pool directory. b43-fwcutter is located on the Ubuntu install media under ../pool/main/b/b43-fwcutter/ and patch is located under ../pool/main/p/patch/ or both in the official repositories online. Note: In some versions (10.04 and 11.04 at least) there is not a /pool/main/p/patch/ If this file is missing then you don't need it. In this case you only need to install /pool/main/b/b43-fwcutter by following the instructions below.

  • How to you solve the problem of implicit locking and parallel execution?

    - by Eonil
    Where the code is: function A() { lock() doSomething() unlock() } We can call A safely from multiple threads, but it never be executed in parallel . For parallel execution, we have to evade all of this code. But the problem is we never know the A is getting lock or not. If we have source code (maybe lucky case), we have to decode all code to know locking is happening or not. This sucks. But even worse is we normally have no source code. It's obvious this kind of hidden locks will become bottleneck of parallel execution even all the other parts are designed for parallel. And also, (1) With locks, execution cannot be parallel. (2) And I can't know whether the locks are used or not in any code. (3) Defensively, I can't make parallel anything! This facts drives me crazy. How do you solve this problem?

  • $ON_USER returning root instead of $USER

    - by Nathanel Titane
    Hello everybody! With Natty coming out soon, I've been at work updating my deployment and self-config script to make my desktop on 11.04 run and look the way I want it to. One bummer is that dbus seems to have changed and does not permit, in the same manner Lucid and Maverick did, the authentication of the current user by terminal call using grep and cat. Ideally, to run the script, I would sudo -s and then launch it as # chmod +x install && ./install Instead of returning my user name.. it now returns root and applies changes to the root profile and aborts whenever paths do not correspond. Here is my script header: #!/bin/bash ON_USER=$(echo ~ | awk -F'/' '{ print $1 $2 $3 }' | sed 's/home//g') export $(grep -v "^#" ~/.dbus/session-bus/`cat /var/lib/dbus/machine-id`-0) if sudo -u $ON_USER test -z "$DBUS_SESSION_BUS_ADDRESS" ; then eval `sudo -u $ON_USER dbus-launch --sh-syntax --exit-with-session` fi RELEASE=$(lsb_release -cs) How could I make it return the actual user now that natty is coming? Thanks for the help

  • Creating Ubuntu bootable disk on my phone

    - by Aerus
    I want to install Ubuntu 12.04 on my laptop but because I have a complete shortage of writable CDs and DVDs, I wan't to create a bootable USB stick (on Windows). However, the only USB stick I currently have lying around is my HTC phone (HTC Touch HD with 8Gb memory). I was following the Ubuntu guide to create a bootable usb stick with pendrivelinux, however in the last step it shows me that it wants to do more than just copying the .iso file to the USB drive: My question: can I safely proceed without wiping the current OS off my phone (Windows Mobile 6.1) and use it to install Ubuntu?

  • Installing RVM on 11.10

    - by Guided33
    I have been trying to get RVM properly installed on my system for 10 hours. The problem is, that when ever I run the command to download the install script I get this: edu@edu-VirtualBox:~$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer) mkdir: cannot create directory `/usr/share/ruby-rvm': Permission denied If I run the command with sudo, I can get it installed, but then that leads to a whole host of other issues. Every tutorial I read says that you should not be installing rvm with sudo for a single user install. Why can I seem to get it installed without running sudo?

  • BizTalk 2009 - Size Functoid Fun

    - by StuartBrierley
    Recently when mapping a flat file from a third party source, I needed to check whether some elements had been sent with any content or not. In the source message these elements were being supplied in the form: <comment /> I though I would try using the size functoid, assuming that it would return a size of 0 for these empty elements.  What actully happens is that the Size funtoid returned a size of 1 rather than the 0 I was expecting. To get what I considered to be the correct output I needed to add a String Right Trim functoid before the Size functoid.  This then returned the "required" size of 0.

  • dpkg reports error on package icaclient

    - by Photonics1
    I installed the icaclient (it's a client for Citrix) a while back. I don't exactly remember what I did to get it working but it was enervating. I had to install some old packages not even avaiable for ubuntu (12.04) and in the end I used some stuff from old rpms. Anyway the client is more or less working now but I always get a dpkg error when installing or updating something. The (translated) error message is something like: dpkg: Error while processing icaclient:i386 (--configure): subprocess installed post-installation-script return errorcode 2 I just want to tell dpkg to ignore this or remove this post-install-script but I don't know how. Thanks!
