• How do I get HDMI out working on an Acer AC700 HDMI?

  - by Kyle

  I have installed Ubuntu on my Acer AC700 (Chromebook) using both the Cr-48 method and the script method both of which I think are the same. The only thing that does not work is HDMI out. I assume this is because it uses the Chrome OS kernel to boot so I have hoped that eventually it would update and work. I'm currently running 12.04 with Kernel 3.4.0 and still no luck. I've tried booting in recovery for Ubuntu and attempting to get Xorg to generate a new config but I don't know enough to do anything else and that didn't work. Am I the only one out there? Is there no one else who wants this to be possible Any help is greatly appreciated.

• Dynamic Post-build event in Visual Studio

  - by SSumner

  I am building a video server application that has multiple projects in Visual Studio. One project, the video server project, needs to call a shell script to generate documentation. This works fine when you build the video server project, because the script is simply cd "$(SolutionDir)" start documentationgenerator However, there is also an SDK project that, when built, also builds the video server project. However, when it does this, it does not know where the shell script is, since it tries to use the SDK Project's Solution Directory. SDK Project Video Server Project shell script So the question is: how do I make the SDK Project find the Video Server Project? I checked the MSBuild properties and there are no properties that seem to deal with 'nested' projects.

• Restricting A Directory Through .htaccess

  - by Whitechapel

  I'm trying to put all of my FTP accounts into a folder on /public_html/ftp and password protect it so search bots can't crawl their private files. I'm also trying to redirect all site traffic from the non-www to www. I keep getting 500 errors when accessing the site, and I need to point it to www.vivalanation.com/ftp to www.vivalanation.com/ftp/, because the /ftp just errors out, you need the trailing slash. Here is my .htaccess in the /public_html/ftp folder: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] AuthName "FTP Access" AuthType Basic AuthUserFile /home1/vivalst/.htpasswds/public_html/ftp/passwd Require valid-user I created a passwd file in /.htpasswds/public_html/ftp And here is my basic .htaccess in the root of /public_html/: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

• Managing a remote ubuntu server

  - by erdomester

  I hire an Ubuntu server which I access remotely and I purchased a domain for my webpage. I am totally new to this server thing and to Ubuntu as well. What applications should I install on the server? I need to transfer files to the server, I guess I would use FileZilla the same way I use it to upload files to my free website. But to have a username and password should I install an ftp server and create a user on Ubuntu? My website will send automated messages to users, so do I need to install a mail server as well? What other software should I install on the server apart from a firewall and an anti-virus? Should I partition the hard drive (3TB) and how? How partitions should I create and in what size for what applications? Btw I use Windows 7 on my computer, so I am basically a windows user.

• How do I install the latest NVIDIA drivers from the .run file?

  - by Shahe Tajiryan

  This is what I am trying to do. I downloaded the latest driver for my VGA from http://www.nvidia.com. The installation needs the X11 to be shut down, so I log out of my account, then press Ctrl+Alt+F1, then log in with my username and password, then run the command sh NVIDIA-Linux-x86_64-285.05.09.run in every possible way, I have even tried CHMODing the package with 777 permissions, but still I'm getting the sh: can't open NVIDIA-Linux-x86_64-285.05.09.run error. Any help would be greatly appreciated.

• juju: How do I list all the relation variables and debug them interactively?

  - by mfisch

  I'm writing a charm that requires a mysql database, I found from looking at other charms that this (below) is how I get the info about the database: user=`relation-get user` password=`relation-get password` mysqlhost=`relation-get private-address` But I just found that from reading the wordpress charm example, is there a way to show all the relation variables that I can use? Also, while debugging my db-relation-changed script, I wanted to ssh into my host and interactively run those commands, for example relation-get user, but it didn't work. I resorted to having to restart everything and use juju log to print them out. This wasted a lot of time. Is there a way to print out these relations, either from my dev box or from the instance running my charm? (Below is what happens when I tried to interactively run relation-get): ubuntu@mfisch-local-tracks-0:~$ relation-get user usage: relation-get [-h] [-o OUTPUT] [-s SOCKET] [--client-id CLIENT_ID] [--format FORMAT] [--log-file FILE] [--log-level CRITICAL|DEBUG|INFO|ERROR|WARNING] [-r RELATION ID] [settings_name] [unit_name] No JUJU_AGENT_SOCKET/-s option found

But I don't understand how that thing I implement in andengnine. Please provide any guidance on how to create image same as user generated polygon shape.

• Is there a standard for machine-readable descriptions of RESTful services?

  - by ecmendenhall

  I've interacted with a few RESTful APIs that provided excellent documentation for humans and descriptive URIs, but none of them seem to return machine-readable descriptions of themselves. It's not too tough to write methods of my own that assemble the right paths, and many language-specific API libraries are already just wrappers around RESTful requests. But the next level of abstraction seems really useful: a library that could read in an API's own machine readable documentation and generate the wrappers automatically, perhaps with a call to some standard URI like base_url + '/documentation' Are there any standards for machine-readable API documentation? Am I doing REST wrong? I am a relatively new programmer, but this seems like a good idea.

• Session locked, Kubuntu 12.10

  - by user101815

  After leaving my laptop for a while, my Kubuntu session closed. (I'm not sure which of the various timeout criteria caused it.) So I got a screen that said my session was locked and I needed to provide my password to unlock it. That's a nuisance, not a big problem, but I'd like to fix it so timed-out sessions don't lock the session. I assume there's something in System Settings to disable the lockout -- but where? I looked in Power Management and found a setting "Lock screen on resume", but it's unchecked. Is this possibly a bug?

• Returning status code where one of many errors could have occured

  - by yttriuszzerbus

  I'm developing a PHP login component which includes functions to manipulate the User object, such as $User->changePassword(string $old, string $new) What I need some advice with is how to return a status, as the function can either succeed (no further information needs to be given) or fail (and the calling code needs to know why, for example incorrect password, database problem etc.) I've come up with the following ideas: Unix-style: return 0 on success, another code on failure. This doesn't seem particularly common in PHP and the language's type-coercion messes with this (a function returning FALSE on success?) This seems to be the best I can think of. Throw an exception on error. PHP's exception support is limited, and this will make life harder for anybody trying to use the functions. Return an array, containing a boolean for "success" or not, and a string or an int for "failure status" if applicable. None of these seem particularly appealing, does anyone have any advice or better ideas?

• Is there a way to develop desktop software using PHP?

  - by user1492018

  I have to develop a real estate marketing CRM software for my client - where the application is installed on desktop but can also be accessed from web. 2 reasons why they want the application to run from desktop : So that it can work with/without internet connection They don't want their complete data to be online They want to access few of the data like property listing & inquiries (managed from desktop application) from their website through secure login & password. The data that is entered in desktop application should be automatically synchronized with the website application. I was wondering if there is a way to develop this kind of software using PHP & MySQL. If yes, it will be great if anyone can provide me the referral link.Else please suggest, which language should I use.

• GPU optimization question: pre-computed or procedural?

  - by Jay

  Good morning, I'm learning shader program and need some general direction. I want to add noise to my laser beam (like this). Which is the best way to handle it? I could pre-compute an image and pass it to the shader. I could then use the image to change the opacity and easily animate the smoke by changing the offset of the texture lookup. I could also generate noise in the shader and do the same thing the texture was used for. Is it generally better to avoid I/O to the graphics card or the opposite? Thanks!

• Writing files to an Airport Extreme using afp

  - by Bill Oldroyd

  Using Nautilus I can connect from Ubuntu 12.04 (64-bit) to my Apple Airport Extreme using user & password without a problem. I can read, browse folders and delete files. However I cannot write files, the file is created, but the contents of the file are not transferred. The transfer fails with the error message "kFPMiscErr" which I think means that "authentication has already been established" ?. I have tried the command line tools for access using AFP but these do not work either. Is there a solution to this problem ?

• What is Rails way to save images?

  - by user

  I develop on iOS, and I'm switching from a PHP backend to Ruby on Rails. The interchange format is JSON. A quick Google search for 'save images in Rails' has nearly every result talking about saving image data as blobs to the database. I might be mistaken, but I'm under the impression that saving image data in a database is a huge waste of time and space (as opposed to saving a link to the file location ('/img/subcat/4656.png'). In PHP, it's pretty standard to receive the data, generate a filename, then save that file to disk, and then update the database with the image's location on disk. Is this the same for Rails, or is there some built-in ActiveRecord image functionality I'm not aware of?

• cannot unlock login screen 14.04

  - by LittleNooby

  When my computer boots, entering the correct password won't start my session. I found out the problem is /home/user/.Xauthority ownership. root owns this folder and giving the ownership to the user will solve the problem... for a while. I don't know how or when, but the ownership will go back to root pretty often; It can happen just after one boot or ten. Is there a definitive solution to this problem?

• How can you procedurally place objects in a non-gridded game?

  - by nickbadal

  This is a follow-up question to this question. I mistakenly worded the question, but got a good answer before I could correct myself, so I didn't want to delete it. Sorry! Now that I know that it is possible, I'd like to implement procedural world generation, but I don't want it to look gridded or blocky, where everything is obviously placed on an integer grid. I know that you can do this in gridded worlds by inputting a square's x and y into a noise function, or similar, but how can I generate a more natural looking object placement using procedural methods? This is in the context of an adventure game, if it matters.

• How to create a map-like (clouds) texture [duplicate]

  - by user16547

  This question already has an answer here: How do you generate tileable Perlin noise? 9 answers If you place a map of the world on a sphere, it will look like the image is continuous. Basically the left end of the image is sort of a continuation of the right end. You won't be able to see any cuts. I'm trying to create a clouds texture to add to my planet such that it will seem it has clouds. I managed to create the clouds in GIMP, however, I can't figure out how to make sure the left end of my image is a smooth continuation of the right end. For example if you were to map the below image to your sphere (I removed transparency to make it clearer), there would be a very obvious transition from the right end of the image back to the left end on your sphere. How would I create a texture such that I get rid of that? Sorry for my lack of terminology.
