• Finding inspiration / help for making up (weapon) names

  - by Rookie

  I'm really bad with words, especially with English words. Currently I'm struggling to make a good weapon names for my game, it needs to display the weapon functionality (weak/strong/fast/ballistic etc) correctly as well. For example the best weapon in a (futuristic) game cannot be called just with the name "Laser", it's just too boring, right? Are there any tools, websites or anything that helps me finding good names for weapons? (or anything else similar). I was thinking to use scientific names, but noticed that they are really hard to write, and they get very long, and I also lack information about science, I only know I could use the atomic sub-particles names in the weapons for example. How do I get started with becoming good with making up names? (this could apply in generally to any naming problems).

• When Your ASP.NET MVC Custom Error Doesn't Render...

  You've put [HandleError] on your controller and you've set <customErrors mode="On"> in the web.config file. So why do you still see the yellow screen of death?

• Where should people give feedback on Ubuntu?

  - by poolie

  Many people have opinions or want to give feedback about Ubuntu. If they are simple bugs with a crash or display corruption, that's fine, they can file in Launchpad. But, comments about the design or concept of the system are more problematic. They come up all over the place, such as "Some Unity feedback" in other places that are not really about Unity. Ideally the answer will be a place where the comments will actually be read by the design team will tend to encourage people to read the existing comments and not post the same thing again and again perhaps will tend to bubble up good solutions rather than strange ideas will not be annoying to people who are trying to use that place for something else

• On-board HDMI Audio

  - by TrackStar

  I have tried searching for answers to this issue but have had no luck. My HDMI display is working but I have no audio from the HDMI .There is no option for HDMI under sound preferences hardware or output. Purging and re-installing pulse audio doesn't change anything. I am using the on-board HDMI port on my motherboard, I do not have a PCI graphics card installed. CPU: i7-3770 Mobo: Asus Sabertooth z77 Kernel: 2.6.39-3-bb03 running aplay -l returns ** List of PLAYBACK Hardware Devices ** card 0: Intel [HDA Intel], device 0: ALC892 Analog [ALC892 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC892 Digital [ALC892 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 Seems as if the system doesn't even recognize the possibilty of HDMI audio output. Any ideas?

• SEO: Joomla Category Page Optimization + Canonical Linking

  - by Huberis

  I'm wondering how best to optimize my Joomla site's SEO. I have pages with multiple articles on each page. Either via category-type pages, or via modules. In each case, I'm not wanting users to access the articles separately from the forward facing, menu-linked pages. I understand however that Joomla still generates a url for those articles, and Google can still crawl and display these articles separate from the pages. My question is what is the best way to control this so that my users get directed only to the front-facing pages? By using the canonical element for each article to point to the front-facing page it's on? Or is there a better method? Thanks for your help!

• Recommend an open source CMS for single page web site

  - by RedMan

  Hi I want to create a single page web site like http://kiskolabs.com/ or http://www.carat.se to display my portfolio. I want to add new products after launching the site without having to edit the entire site. I've looked at opencart (too much for single page site), Magneto (more for ecommerce), Wordpress (couldn't find open source / free templates which i can start from). Can you suggest a CMS which will support the creation of a single page site and allow insertion of new products without having to edit the entire page? I would prefer a CMS which also has open source / free templates which I can tweak for my use. I can do php and mysql, xml. If it is an easier option I can do PSD to site (but don't know much about this at all).

• "A hard disk may be failing" , but no additional info via gdu-notification-deamon (suggestions?)

  - by blunders

  Got this message after logging in: A hard disk may be failing One or more hard disk report health problems. Click the icon to get more information. On WUBI and 10.04, there was no icon to click, and clicking on made the message go away. After rebooting, the message did not display again. I've got everything on all my hard drives in duplicate, so not super worried about a disk failure, though I am wondering why the message had no info on which disk it thought had problems. Suggestions?

• Multi Column Block Too Narrow in Chrome

  - by aksarben

  My Web site displays song lyrics in a multi-column format, using CSS3. Both Firefox & MSIE 10+ display the multi-column text perfectly, but Chrome does not. This sample page shows the problem: http://www.hymntime.com/tch/test/html5/html5-multicolumn-test.htm The page uses a media selector, so your Chrome window must be at least 1280 pixels wide to see the effect. In fact, if you make the Chrome window less than 1280 pixels, you'll see the lyrics block change to a single column, of the same overall width. In other words, when Chrome shifts to 1-column to 2-column mode (due to the wider browser window), the lyrics block remains the same width, causing text to be squeezed together. Has anyone else seen this behavior, or know a solution? Is this a Chrome bug, or I am I doing something wrong? I posted this question on a Chrome forum a while back, but got no reply.

• Remove a bad/erroneous WebPart from a SharePoint page

  - by KunaalKapoor

  If you've added a poorly written webpart to your 'default.aspx' page, the consequence of this action will be that you won't be able to load the page anymore... Don't be sad, there is still a way to remove the webpart from the page :) (Yes, even removing the webpart from the webpart gallery would not solve this issue).Steps to fix this:1. Append the following query string to your URL: ?Contents=1.Once you've added Contents=1 as a query string to the webpart page's URL it will display the Webpart Maintenance Page. Example: http://mysharepointserver/default.aspx?contents=12. On that page you can now see the webparts added to the page, delete the problematic webpart.Now try reloading the default.aspx page... Tadaaa!!! you can view your page again :)3. Leave a thank you note @ comments section :)

• What video graphic card would permit ubuntu's standard driver to work well?

  - by Rick

  I installed ubuntu 12.04. All seemed well until I installed the nvidia driver. Then crashola! This situation is untenable. It seems I cannot trust nvidia, and it seems that I cannot rely on ubuntu gurus to test 3rd party drivers. So, apparently some video card manufacturers do not care enough about the linux market to test their drivers, or are there too many 3rd party video cards so that ubuntu folks do not test any 3rd party video drivers? Hence the question: What video graphic card would permit me to use ubuntu's standard driver so that I do not have to rely on nvidia's or any other 3rd-party driver? Perhaps I could then install THAT card and have things work? The ubuntu standard driver actually worked prior to installing the nvidia driver, but not well, and that was because the display flickered, and flickering gives me a headache.

• Is it possible to install Ubuntu 10.10 and/or Ubuntu 11.04 on a late 2009 iMac?

  - by Oliver

  I would like to install Ubuntu on my iMac 10,1 (21.5 inch display). I would prefer to instal Natty Narwhal, but would surely settle for Maverick Meerkat (which I have a install dvd of). I have an install of OS X Snow Leopard AND a Bootcamp Partition of Windows 7. I would like to keep all these partitions and setup a triple boot system. If it can work, I'm also wondering if it'd be safe to install all updates from the update manager once it's installed. Thank you in advance. :)

• VMMap - awesome memory analysis tool

  VMMap is a process virtual and physical memory analysis utility. It shows a breakdown of a process's committed virtual memory types as well as the amount of physical memory (working set) assigned by the operating system to those types. Besides graphical representations of memory usage, VMMap also shows summary information and a detailed process memory map. Powerful filtering and refresh capabilities allow you to identify the sources of process memory usage and the memory cost of application features. Besides flexible views for analyzing live processes, VMMap supports the export of data in multiple forms, including a native format that preserves all the information so that you can load back in. It also includes command-line options that enable scripting scenarios. VMMap is the ideal tool for developers wanting to understand and optimize their application's memory resource usage. span.fullpost {display:none;}

• how to find 3g modem signal strength with out AT commands?

  - by neckTwi

  when i try to find signal strength of my modem using AT+CSQ, the usb device is locked by the network manager. To find the signal strength with AT+CSQ i have to first disable network connection using #nmcli nm wwan off to unlock the device inode /dev/ttyUSBX. Is there any nmcli option to get signal strength or any other option? EDIT The gdbus object for NetworkManager don't have any method like getSignalStrength. Network manager is locking device file preventing to use AT commands. nm-applet was able to display signal strength in system tray. so there should be a way to get signal strength form network manager! nmcli is command line counter part of nm-applet. Can i get signal strength using nmcli? nothing about signal strength is mentioned in its man pages.

• Setting umask globally

  - by DevSolar

  I am using a private user group setup, i.e. a user foo's home directory is owned by foo:foo, not foo:users. For this to work, I need to set the umask to 002 globally. After a quick grep -RIi umask /etc/*, it seemed for a moment that modifying the UMASK entry in /etc/login.defs should do the trick. It does, too -- but only for console logins. If I log in to my desktop, and open a terminal there, I still get to see the default umask 022. Same goes for files created from apps started through the menu. Apparently, the display manager (or whatever X11 component responsible) does source some different setting than a console login does, and damned if I could tell which one it is. (I tried changing the setting in /etc/init.d/rc, and no, it did not help.) How / where do I set umask globally, so that the X11 desktop environment gets the memo as well?

• Corona sdk events dispatched with dispatchEvent() are handled directly upon call. Why so?

  - by Amoxus

  I noticed to my surprise that an event created with dispatchEvent(event) gets handled directly when called, and not together with other events at a specific phase of the frame loop. Two main reasons of having an event system are: so that you can call code B from code A, but still want to prioritize code A. to make sure there are no freaky loopedy loops where code A calls code B calls code A ... I wonder what Ansca's rationale behind having events being handled directly this way is. And does Corona handle loopedy loops and other such pitfalls gracefully? The following code demonstrates dispatchEvent(): T= {} Z = display.newRect(100,100,100,100) function T.doSomething() print("T.doSomething: begun") local event = { name="myEventType", target=T } Z:dispatchEvent( event ) print("T.doSomething: ended") end function Z.sayHello(event) print("Z.sayHello: begun and ended") end Z:addEventListener("myEventType", Z.sayHello) print("Main: begun") T.doSomething() print("Main: ended") However Ansca claims the contrary at http://developer.coronalabs.com/reference/index/objectdispatchevent Can anyone clear this up a little? ( Using Corona simulator V 2012.840 )

• What is a light-weight "slideshow" script that could integrate w/ CMS?

  - by aslum

  I'm looking to reduce the footprint of my Strict html 4.01 front page. One possible way is to combine much of the "upcoming events" into a single small box, and have them automagically switch which one is displayed every few seconds. I'm sure there are a bunch of this kind of thing written already, and surely an open source one exists, but I haven't had much luck find one. I'd prefer javascript to jQuery as installing jQuery might not be an option, but if the best-fit script requires jQuery I'd certainly be willing to investigate that route. If it can display content from Wordpress that would be ideal.

• -webkit-linear-gradient Not working in Dreamweaver CS6

  - by Ken

  I've tried multiple times to apply the following piece of code in a CSS document: display: block; width: 500px; margin: 500px auto; padding: 15px; text-align: center; border: 4px solid blue; background: -webkit-linear-gradient(top,black,white); outline: 7px solid red; Everything appears correctly, except the gradient. I have CS6 Live View turned on, and it still refuses to appear. All I get in my box is a white background, as opposed to the black to white gradient. However, when I type the same line of code into the trial of Coda 2 I downloaded, it works perfectly. Is there anything I can do to resolve the issue?

• How to do pre-loading

  - by Dave

  I have a question that is confusing me with making a game. For my game launch i pre load everything for the main menu then i loop the game to display it. But lets argue player wants to launch a new game or a specific level, then you preload the relevant sounds/graphics for that level right? How ever, the player must already be running the game loop if they are at the main menu, so you can't load in the game loop or you will load every frame...but im pretty sure most big games don't preload every level when you first run the game from desktop because it would take a long time on some of these games.... How is it done :S

• If I intend to use Hadoop is there a difference in 12.04 LTS 64 Desktop and Server?

  - by Charles Daringer

  Sorry for such a Newbie Question, but I'm looking at installing M3 edition of MapR the requirements are at this link: http://www.mapr.com/doc/display/MapR/Requirements+for+Installation And my question is this, is the Desktop Kernel 64 for 12.04 LTS adequate or the "same" as the Server version of the product? If I'm setting up a lab to attempt to install a home cluster environment should I start with the Server or Dual Boot that distribution? My assumption is that the two are the same. That I can add any additional software to the 64 as needed. Can anyone elaborate on this? Have I missed something obvious?
