    - by Bob Rhubart
    Registration is now open for the Architect Day events in Dallas TX (5/13), Redwood Shores CA (5/18), and  Anaheim CA (5/19). These events are free and offer a full slate of presentations and discussions covering a broad range of topics of interest to architects. The agenda for each location includes guest keynotes by members of the Oracle ACE community, breakout sessions, panel discussions, and  roundtable discussions in which all attendees get a chance share their insight and expertise. All that, and you get a free lunch plus an end of day reception. What’s not to like? Seating for these free events is limited, so if you snooze, you lose. I’ll be at the Dallas event. Hope to see you there.   Technorati Tags: oracle,oracle technology network,software architect,events,conference del.icio.us Tags: oracle,oracle technology network,software architect,events,conference

  • How do you run XBMC on nvidia dual screen and stop it from taking over the keyboard and mouse?

    - by Paul Swartout
    I have set up dual screen under Ubuntu 12.04. I have a GeForce 8500 GT and have used the nVidia control panel to set up dual screen in "Separate screen mode". Here's the resulting xorg.conf # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 295.33 (buildd@zirconium) Fri Mar 30 13:38:49 UTC 2012 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "Maxdata/Belinea B1925S1W" HorizSync 31.0 - 83.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Monitor" # HorizSync source: builtin, VertRefresh source: builtin Identifier "Monitor1" VendorName "Unknown" ModelName "CRT-1" HorizSync 28.0 - 55.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 8500 GT" BusID "PCI:1:0:0" Screen 0 EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 8500 GT" BusID "PCI:1:0:0" Screen 1 EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "CRT-0: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" # Removed Option "metamodes" "CRT-1: 1280x768 +0+0" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "CRT-1: 1360x768_60 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection All well and good and I have a nice blank XWindow displayed on my TV (the 2nd monitor). I then fire up XBMC from a terminal on the PC monitor using DISPLAY=:0.1 xbmc XBMC fires up quite nicely on the TV however I can no longer use the main PC monitor / mouse / keyboard as XBMC on the TV screen seems to have focus. I was hoping to have XBMC running on the TV and let the kids use the MCE remote whilst I get on with my work on the PC monitor. Does anyone have any idea how to overcome this? I'm presuming there's some xorg.conf fun and games needed but I've no idea where to start to be honest.

  • Do big domain sellers ever stop renewing their domains? [on hold]

    - by nctrnl
    There are many companies out there who register tons of domains that they have no plans to use except for trying to sell them for a ridiculously high price. One domain name in particular was registered in year 2000 and hasn't been in use since then other than as a temporary redirect website for about a month (when checking web.archive.org). It makes me furious that this behaviour has not been outlawed yet. I wonder if it's even worth to wait for a .com domain to expire anymore? Do you have any success stories to share?

  • How do I stop color changes when quitting vi from a terminal emulator?

    - by Michael Warhol
    I have a problem with colors when using vi under Ubuntu 12.04. I'm connecting to my Ubuntu server from a PC, using PowerTerm terminal emulation software. I have PowerTerm set up to display black text on a grey background. When I connect to the Ubuntu box, the screen is fine. When I open a file with vi, the screen is fine. The text is black on a gray background, which is normal for my PowerTerm setup. However, if the file is less than a full screen long, the remainder of the screen is a black background. When I quit vi, the entire background turns black, and the text becomes white. I have to do a Terminal Reset to restore my normal text and background colors. What I want is for there to be no change at all when I use vi. The text should be black and the background grey. I have another server loaded with RedHat 9, and that acts normally; colors don’t change when using vi. Here is my .vimrc file: set compatible syntax off let g:loaded_matchparen=1 set nocp set noincsearch set nohlsearch set noshowmatch set bg=dark I've tried set bg=dark and set bg=light. It makes no difference. Is there some other set command that would clear this up for me, or some TERM setting (my TERM is set to linux)?

  • Unity elements sometimes appear while full screen in Virtualbox - how to stop it?

    - by frumbert
    Launcher is great, and it helps me finds stuff. I have the latest release of 12. But when I'm full screen in VirtualBox running another operating system and I hit some key combination I haven't yet figured out, Unity suddenly grabs keyboard focus. It might be alt-tab, it might be left-control x. I have physically pulled both the windows key and FN key off my laptop because they get in the way, so it's probably not the windows key. You don't know the focus has been stolen because the full screen app (VirtualBox) is still full screen and the Unity element is in the background. But you're busy typing into a Unity box, not your foreground application. This is particularly annoying. In my screenshot (taken from a camera, because the built in screen capture program can't capture a screenshot containing the launcher...) the windows VM is the foreground application, but the "Run Command" entry box has come up and is capturing the keyboard: I would like a foreground full screen app to stay that way. Is there a way that I can keep Unity but only have it activate its elements (e.g. pop out with its search box) if I physically click a button, not type some random key combination that foreground applications can get confused about? Otherwise I can do without the launcher or other elements, because doing my actual work is more involved than just launching programs.

  • How to get the Dash and HUD to appear. (and stop Unity spewing error messages.)

    - by Ubuntiac
    I just installed Ubuntu 12.04 on my wifes Dell Inspiron 1501, which uses an R300 ATI graphics chip. Neither the Dash or HUD appear when pushing the appropriate key. When I try unity --reset & in the terminal, I see that over and over it's spitting out: r300: CS space validation failed. (not enough memory?) Skipping rendering. This is just after starting Ubuntu with no apps open, so I find it hard to believe that just rendering the Dash / HUD is completely blowing out the VRAM. Any suggestions on getting this working? /usr/lib/nux/unity_support_test -p shows OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RS480 OpenGL version string: 2.1 Mesa 8.0.2 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes All sections say "YES"

  • jQuery slide open and close menus. How to stop them going crazy? [closed]

    - by firefusion
    I want sub menu's of a verticle menu to expand and collapse when moused over. This is what i've got so far but it goes crazy if you do it to quick as all the animations run at once and on a delay. How can i make sure just one menu expands at a time. I've also set the current_page_item to be open but default and I don't want this to expand or collaspe. <ul> <li class="current_page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a></li> <li class="page_item"><a href="#">Parent Item</a></li> </ul> jQuery('ul.children').hide(); jQuery('li.current_page_item ul.children').show(); jQuery('li.current_page_item').parent().show(); jQuery("li.page_item").hover(function() { jQuery(this).find('ul.children').delay(300).slideDown('slow'); }, function() { jQuery(this).find('ul.children').delay(300).slideUp('slow'); });

  • How can I stop my Jitter physics meshes being offset?

    - by ben1066
    I'm developing a C# game engine and have hit a snag trying to add physics. I'm using XNA for graphics and Jitter for physics. I am trying to split the XNA model into it's meshes, then create a ConvexHull for each mesh. I then attempt to combine those into a CompoundObject, this however isn't working and depending upon the model the meshes are offset by different amounts. This is the code I'm currently using and it gives me: Any ideas?

  • How can I stop the panel from showing on an external projector/monitor?

    - by hellocatfood
    In Ubuntu 10.10 (and possibly previous versions), when I connected my laptop to an external source (monitor/projector) and set it not to clone my desktop the display on the external source would not show the (gnome-)panel (just a full-screen desktop with no icons). Since upgrading to Ubuntu 11.04 (using Unity) when I now connect the external source has the panel on there. Is there any way to revert to the previous behaviour in 11.04?

  • How to make grub stop appearing every time I boot?

    - by Justin Riddiough
    I'm using Ubuntu 12.04 and grub selections appear each time I boot. This happens on both of my computers.

  • How do I prevent Ubuntu gradually slowing down to a stop?

    - by user29165
    I really do not know what is causing the problem of my desktop environment (D.E.) gradually slowing down. It seems to happen in Gnome 3.2, LXDE, XFCE, and KDE. I am running Ubuntu 11.10 and this problem started happening from a fresh install. I have noticed that if I restart Gnome or otherwise re-log-in with any of the D.E.s the speed resets to normal. I don't seem to have and memory leaks that account for it and there are not any processes that are using excessive CPU cycles. Due to the symptoms I am guessing that there is an underlying package that interacts with all D.E.s that is the source of the problem. Just to clarify, in extreme situations, if I let the slowdown continue without a restart of the D.E. my system will finally get to a point where everything, even my clock, freezes. The time over which Gnome slows down (noticeably after 17 hrs) is much less than LXDE, or XFCE but eventually they freeze as well. I didn't mention Unity since I haven't used it enough to verify the problem, but I don't see why it should be different. Just in case this is relevant, I Suspend my computer rather than turn it off. I do this because of the greatly reduced load time and the 17 hrs I stated above is actual up-time, not time where the D.E. is actually active. However, the slow down does not seem to be affected by how long the computer has been in suspend mode. I know that it is possible that this problem is due to an interaction between two or more of the applications that I use and as such it may not be able to be duplicated by others. In the end I am just wondering (a) are other people experiencing this issue and (b) does anyone have some advice on where to start looking for a solution if one is not already known. I am even open to the idea of switching to the beta release of 12.04 if anyone thinks it will solve the problem. Edit: I took a video of my latest freeze that you can watch at http://youtu.be/flKUqUzCmdE, sorry about the audio. Edit: Since that video I checked my memory for errors and tried installing the proprietary video drivers. No memory errors were found and the proprietary video drivers made the display unusable so I had to uninstall them. Any thoughts?

  • How do I stop banshee remembering what's been played?

    - by dunderhead
    How can I prevent Banshee from remembering what files I have played? I really hate the way it keeps surprising me by automatically playing, after the current track, the previous file it had played. I really HATE that. I was just listening to a beautiful piece of music and in a nice mood when Banshee, without asking me, immediately afterwards, started playing a really annoying answerphone message from earlier. My solution so far is to manually delete all files in the playlist, but obviously that's not a long term solution. I cannot find an option anywhere that says "Do not remember my history" (Did I mention I hate the way Banshee plays my files without asking me?)

  • How can I stop pixel seams appearing in adjacent mesh boundaries due to floating point imprecision?

    - by ufomorace
    Graphics cards are mathematically imprecise. So when some meshes are joined by their borders, the graphics card often makes mistakes and decides that some pixels at the seam represent neither object, and unwanted pixels appear. It's a natural behaviour on all graphics cards. How are such worries avoided in Pro Games? Batching? Shaders? Different tangent vectors? Merging? Overlaping seams? Dark backgrounds? Extra vertices at borders? Z precision? Camera distance tweaks? Screencap of a fix that ended up not working:

  • how to get bash to stop escaping $ during tab-completion?

    - by keturn
    I have this on the command line: ln -sf $PWD/wine- and then I hit tab to complete the filename. In earlier versions of Ubuntu, this worked just fine to complete the wine- filename (and as a side-effect $PWD would be expanded at that time). But now it turns it in to ln -sf \$PWD/wine- which isn't what I meant at all and doesn't complete anything as the file does not literally start with $. How do I get completion back to the less broken behaviour? set tells me these are my current settings: BASHOPTS=checkwinsize:cmdhist:expand_aliases:extquote:force_fignore:hostcomplete:interactive_comments:progcomp:promptvars:sourcepath SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitor

  • Possible to stop Adobe DreamWeaver from rewriting 'onclick' to 'onClick'? [closed]

    - by DA01
    I've been giving my dev team grief by checking in HTML edited in DW. It turns out that DW has silently been rewriting all instances of 'onclick' to 'onClick' completely breaking the application in Webkit on us. I've done some digging on Google and this appears to be a bug that goes back to at least 2004. Supposedly it has nothing to do with your code re-writing settings and what triggers it is opening any document that does not contain a Doctype. Few of ours do, given that we're maintaining a framework that's using all sorts of include and dependency files. In all my Googling, I haven't found a fix, though. Has anyone come across one short of swearing off Adobe products forever?* something, btw, that I'm perfectly fine doing...it's just that given the insane IT lockdown on our work machines, we have very few software choices. For now, It's Notepad++ for me.

  • STOP! Wrong Server!

    - by merrillaldrich
    Some time ago I wrote a post about old-time T-SQL flow control . Part of the idea was to illustrate how to make scripts abort on errors, which is surprisingly convoluted in T-SQL. Today I have a more specific example: how can I check that we are really about to execute in the right database on the right server, and halt if not. Perhaps you’ve connected to the wrong server, or the database you intend to modify doesn’t have the name your script expected. “USE database” is wonderful, but what if it...(read more)

  • Launchctl: how can I configure a service to stop restarting automatically until next reboot?

    - by Andrew J. Brehm
    I have several services set up in launchctl and they all start at boot and restart automatically whenever they stop for any reason. That's great so far. But sometimes I want one of the services to quit and not restart for a while. Is there a recommended way to do that apart from removing the service from launchctl (which also stops it immediately, which I don't want to do)?

  • How to stop Windows Server Standard from booting me while remoted in?

    - by Mike Pateras
    I'm using Remote Desktop connection to connect to a Windows Server box, on which I am an admit. If I'm idle for a few minutes, it locks me out (killing file transfers, which is a problem), and a few minutes after that, it severs my connection. Where can I find the settings that govern these things to stop that from happening? I want it to let me stay connected, regardless if I'm idle.

  • How to stop switchable graphics from switching to high-power GPU when charging the laptop?

    - by Saifallah
    I've an Acer laptop with Windows 7 64 bit and an ATI Radeon HD 6550M Graphics card. Whenever I connect the power to charge the battery it automatically switches to the high-power GPU (ATI) instead of the low-power (Intel) GPU. There's an option in the bios to stop such thing but it makes the GPU runs always on high-power and I can't switch to the low-power GPU. How can I prevent the switchable graphics from automatically using the high-power GPU when charging?

  • How to conform to update-rc.d with LSB standard?

    - by user34881
    This is a migrated question from stackoverflow, as I was told, this is the place for it to be. http://stackoverflow.com/questions/2263567/how-to-conform-to-update-rc-d-with-lsb-standard I have set up a simple script to back up some directories. While I haven't had any problems setting up the functionality, I'm stuck with adding the script to rcX.d dir's using update-rc.d. My script: #! /bin/sh ### BEGIN INIT INFO # Provides: backup # Required-Start: backup # Required-Stop: # Should-Stop: # Default-Start: 0 6 # Default-Stop: # Description: Backs up some dirs ### END INIT INFO check_mounted() { # Check if HD is mounted } do_backup() { if check_mounted; then # Some rsync statements. fi } case "$1" in start) do_backup ;; restart|reload|force-reload) echo "Error: argument '$1' not supported" >&2 exit 3 ;; stop|"") # No-op ;; *) echo "Usage: backup [start]" >&2 exit 3 ;; esac : Using update-rc.d backup start 10 0 6 . I get the following warnings and errors: update-rc.d: warning: backup start runlevel arguments (none) do not match LSB Default-Start values (0 6) update-rc.d: warning: backup stop runlevel arguments (0 6.) do not match LSB Default-Stop values (none) update-rc.d: error: start|stop arguments not terminated by "." The syntax I try to use is the following: update-rc.d [-n] <basename> start|stop NN runlvl [runlvl] [...] . Google wasn't that helpful at finding a solution. How can I correctly set up a script and add it via update-rc.d? I'm using Ubuntu 9.10. UPDATE Using update-rc.d backup start 10 0 6 . stop 10 0 . the error disappears. The warnings about default values persists: update-rc.d: warning: backup start runlevel arguments (none) do not match LSB Default-Start values (0 6) update-rc.d: warning: backup stop runlevel arguments (0 6 0 6) do not match LSB Default-Stop values (none) It even is added to the appropiate rcX-dirs but it still does not get executed...
