  • '/'var/www/' vs '/home/$USER/public_html'

    - by OrganizedFellow
    I recently started using Ubuntu as a LAMP server. I've come across plenty of tutorials that say to place the files at '/var/www/' and I've also seen others that put them in '/home/$USER/public_html/'. During my testing and figuring stuff out, I was successfully able to view a test site URL from each location. Is one better than the other? I thought that maybe it was just preference. But the more I think about it, the more I want to keep all my work in my Home folder.

  • Help me i can't format my usb? i have already tried with mkdosfs and gparted

    - by Mauri Olivares
    I have a MicroSD card in a USB adapter (which plugs into a USB port on my machine, and acts like a USB flash drive). I was using Unetbootin to make this a bootable USB flash drive with Kubuntu. But I needed to cancel while it was working. So I killed the Unetbootin process from the console. Since then, I can't format the MicroSD or delete the folder that Kubuntu made. I have also tried mkdosfs, with no success. I can't mount the drive anymore either? What can I do, to make this drive usable again? Trying to create a new partition table in GParted, as described in Eliah Kagan's answer, does not work. It fails with the error message "imposible crear tabla de particiones" ("unable to create a partition table").

  • How to change icons of specific file types on Ubuntu 11.10?

    - by Curious Apprentice
    I want to change file icons of some specific file types like- .html, .css etc. I have tried using "File Type Editor (assogiate)" which is not working. I have also tried using "Gnome Tweak Tool" using icon themes. But that also does not worked properly (Though I can change folder icons , dash menu icons but not file icons). Please suggest me a way so that I can change file icons properly. I have read some of the articles saying about some mime type changes. I could not get proper guide from any of those articles. If there is such a way then please write in detail. Many Many Thanks in Advance :)

  • Whats a good structure to save and retrieve locations of images?

    - by Goot
    I got a java-ee application, where I collect informations about movies. Im my backend I provide data like the name, description, genre and a random uuid. I also got lots of related files, which are stored on a file server. Including some screenshots, the dvd or bluRay cover and video trailers. My current approach is: When saving the files to the fileserver, I retrieve the movies random uuid (which is the primary key btw.). I then rename the files screenshot_[UUID]_1, screenshot_[UUID]_2 ... etc. Now, there are lots of other ways to handle this, like saving all filenames in a database or creating a dir structure on the fileserver for every uuid and, e.g., return all images in the "[uuid]/screenshots" folder via REST. I expect about 30k requests a day, so the service has to be pretty performant. Whats the best way to solve this?

  • What did I do wrong when installed this theme?

    - by Qmal
    I have a problem installing a theme for my Ubuntu, note that I am very new to it and probably messed something up. Still it seems to me that I did everything like it was stated in the INSTALL file. Theme: http://opendesktop.org/content/show.php/?content=140562 So I downloaded the *.zip package, unzipped it in home/.themes folder and changed Controls and Borders inside my theme preference. Still my result is pretty poor. You can look at the image, it looks nothing like what in the screenshot of the author. I also installed fonts running sudo apt-get install ttf-mscorefonts-installer and tried to install GTK2 engine as sudo apt-get install gtk2-engines-murrine gtk2-engines-pixbuf, but it showed that 0 files was modified since I already have it. Please tell me what did I did wrong so I can fix that :) (It seems that I can't upload images yet, no rep. I can give you link tho) http://postimage.org/image/1zhibxx5w/full/

  • Animating isometric sprites

    - by Mike
    I'm having trouble coming up with a way to animate these 2D isometric sprites. The sprites are stored like this: < Game Folder Root /Assets/Sprites/< Sprite Name /< Sprite Animation /< Sprite Direction /< Frame Number .png So for example, /Assets/Sprites/Worker/Stand/North-East/01.png Sprite sheets aren't really viable for this type of animation. The example stand animation is 61 frames. 61 frames for all 8 directions alone is huge, but there's more then just a standing animation for each sprite. Creating an sf::Texture for every image and every frame seems like it will take up a lot of memory and be hard to keep track of that many images. Unloading the image and loading the next one every single frame seems like it will do a lot of unnecessary work. What's the best way to handle this?

  • Mobile music playback on android phone keeps buffering

    - by ianio
    I have copied some music to a ubuntu synced folder on my karmic machine. I have the Ubuntu One android app installed on android 2.2 phone. When listening to music I get frequent breaks whilst the music is buffering, even with full signal. every other music streaming servie such as last fm and bbc player are fine. What is going wrong? mp3s should not have trouble buffering over a good 3g signal. I have set cache size to 200mb but i cant find a buffer size. Is it my mp3s? they are usually in the order of 320kb/s this is a breaker for me if there is no solution which is a massive shame as i like the principal of the software. cheers

  • Gnome 3 - Old fashioned buttons and menus

    - by vigs1990
    I've upgraded to Gnome 3 and the problem I'm facing is that when I restart, sometimes the menus and buttons look old-fashioned like this: whereas sometimes, it looks modern and neat like this: Notice the differences between the two: here are a few differences: The menu bar (notice the difference in fonts, dark grey color of Snapshot1 vs the light grey color in Snapshot2 in the background) The file navigation bar bellow the menu bar (notice the 'Home' button there and also the left arrow button) The left-hand side navigation bar (font, background color and color of selected folder) The old style look effects the GTK aspects of the interface, such as the menu, buttons, mouse pointer etc. Another observation is that changing the GTK themes does using gnome-tweak-tool when the old style look is loaded does NOT work. However, this works when the regular look is loaded. How can I ensure that the old-fashioned look does not load on boot?

  • LibGDX - SpriteBatch's .draw() method requiring float[]

    - by just_a_programmer
    Please excuse my lack of knowledge with LibGDX, as I have just started learning it. I am going through some simple tutorials, and in one of them, I draw a string onto the screen like so: // the following code is in the main file in the core project folder: // this is in the create() method: private SpriteBatch batch; batch = new SpriteBatch(); // this is in the render() method: batch.draw(batch, "Hello world", 200, 200); I am getting an error saying: The method draw(texture, float[], int, int) in the type SpriteBatch is not applicable for the arguments (SpriteBatch, int, int) So, LibGDX wants a float array to draw instead of a string? Thanks in advance.

  • Trouble installing downloaded program

    - by Hamlette
    I purchased and downloaded Celtx and I'm having trouble installing it (in Ubuntu 13.04). I'm a Linux newbie (literally had it for four days) so please be kind and don't assume much experience with the command line, I'm still learning. The folder with all related files/packages etc. is under "Downloads" and I have tried several commands to try and install but I'm just not doing it right and would appreciate help with exactly what command(s) to use. Sudo apt-get install celtx did not work. I'm assuming I'm missing a step somewhere.

  • UK OUG Conference Highlights and Insights

    - by Richard Bingham
    As per my preemptive post, this was the first time the annual conference organized by the UK Oracle User Group (UKOUG) was split into two events, one for Oracle Applications and another in December for Oracle Technology. Apps13, as it was branded, was hailed as a success, with over 1000 registered attendees and three days of sessions, exhibition, round-tables and many other types of content. As this poster on their stand illustrates, the UKOUG is a strong community with popular participants from both big and small Oracle partners and customers. The venue was a more intimate setting than previous years also, allowing everyone to casually bump into those they hoped to. It gave a real feeling of an Apps Community. The main themes over the days where CRM and Customer Experience, HCM, and FIN/SCM. This allowed people to attend just one focused day if they wanted. In addition the Apps Transformation stream ran across all three days, offering insights, advice, and details on the newer product solutions like Fusion Applications.  Here are some of the key take-aways I got from the conference, specific to my role in Fusion Applications Developer Relations: User Experience continues to be a significant reason for adopting some of the newer application products available, with immediately obvious gains in user productivity and satisfaction reported by customers. Also this doesn't stop with the baked-in UX either, with their Design Patterns proving popular and indeed currently being extended to including things like extending on ADF mobile and customizing the Simplified UI. More on this to come from us soon. The executive sessions emphasized the "it's a journey" phrase, illustrating that modern business applications are powered by technologies such as Cloud, Mobile, Social and Big Data and these can be harnessed to help propel your organization forward. Indeed the emphasis is away from the traditional vendor prescribed linear applications road map, and towards plotting a course based on business priorities supported by a broad range of integrated solutions. To help with this several conference sessions demoed the new "Applications Navigator" tool, developed in partnership with OUG members, which offers a visual framework to help organizations plan their Oracle Applications investments around business and technology imperatives. Initial reaction was positive, especially as customers do not need to decipher Oracle's huge product catalog and embeds the best blend of proven and integrated applications solutions. We'll share more on this when it is generally available. Several sessions focused around explanations and interpretation of Oracle OpenWorld 2013, helping highlight the key Oracle Applications messages and directions. With a relative small percentage of conference attendees also at OpenWorld (from a show of hands) this was a popular way to distill the information available down into specific items of interest for the community. Please note the original OpenWorld 2013 content is still available for download but will not remain available forever (via the Oracle website OpenWorld Content Catalog > pick a session > see the PDF download). With the release of E-Business Suite 12.2 the move to develop and deploy on the Fusion Middleware stack becomes a reality for many Oracle Applications customers. This coupled with recent E-Business Suite features such as the Integrated SOA Gateway and the E-Business Suite SDK for Java, illustrates how the gap between the technologies and techniques involved in extending E-Business Suite and Fusion Applications is quickly narrowing. We'll see this merging continue to evolve going forwards. Getting started with Oracle Cloud Applications is actually easier than many customers expected, with a broad selection of both large and medium sized organizations explaining how they added new features to their existing Oracle Applications portfolios. New functionality available from Fusion HCM and CX are popular extensions that do not have to disrupt those core business services. Coexistence is the buzzword here, and the available integration is also simpler than many expected, commonly involving an initial setup data load, then regularly incremental synchronizations, often without a need for real-time constant communication between systems. With much of this pre-built already the implementation process is also quite rapid. With most people dressed in suits, we wanted to get the conversations going without the traditional english reserve, so we decided to make ourselves a bit more obvious, as the photo below shows. This seemed to be quite successful and helped those interested identify and approach us. Keep a look out for similar again. In fact if you're in the UK there is an "Apps Transformation Day" planned by the UKOUG for the 19th March 2014, with more details to follow. Again something we'll be sure to participate in. I am hoping to attend the next half of the UKOUG annual conference, Tech13, that focuses more on Oracle technology and where there is more likely to be larger attendance of those interested in the lower-level aspects of applications customization and development. If you're going, let me know and maybe we can meet up.

  • Add rules (filters) to ftp programs to avoid uploading certain files/folders

    - by guisasso
    i use Filezilla as my ftp client, but this question goes to any other client that could be useful. Can i (in any client) add rules (filters) to an ftp program to avoid upload of certain files or folders? For example: Expression web creates those annoying _vti_cnf folders, or, certain folders in which i have the original version of a picture without a watermark that i don't want to upload. Example, i have a folder A, that has sub folders "original" and "current", i would like to add a filter, so every time i select A to be uploaded, "original" wouldn't go, but "current would".

  • Installing Ruby on Rails without access to command line

    - by Darwin
    I'm VERY new to this whole web dev thing but I can program and I liked Ruby when I used it before. Now, I've got web hosting and a domain and a site on there that's currently ran under Joomla but I'd like to experiment with Rails. The most access I can get to the server is FTP and maybe a setting here and there in the control panel. Definitely no command line. Is there a way to just, I don't know, upload ruby on rails to a folder and run it in a browser? That's how Joomla works I think. Literally every article I read about this starts with "you just do sudo get..." mumbo jumbo.

  • How do I make Unity quit opening Firefox under the Shiretoko icon?

    - by Azendale
    I'm using Ubuntu 12.04, and whenever I open Firefox, whether it is from searching on the dash or clicking a 'quick-launch' launcher, it always opens yet another icon for the running instance that is a blank page and says Shiretoko. It will pulse the Firefox icon for a while (I'm guessing until a timeout or something). It's as if Unity no longer recognizes the Firefox process as Firefox and misidentifies it as Shiretoko. (I know Shiretoko was a testing version of Firefox a long time ago.) How do I set Unity straight? I imagine that it has something to do with me once using Shiretoko, but I believe that was even on a different installation, just the same home folder. Is there some place Unity caches this information that I can clear (or remove specific parts of)?

  • Migrate from Thunderbird to Mutt

    - by deshmukh
    I am contemplating moving from Thunderbird to Mutt (provided it is feasible) to move to a faster, simpler application. My current Thunderbird set-up consists of multiple IMAP accounts (gmail and google apps). Only selected folders (read labels) in each IMAP account are stored locally. For all other folders, I glance through the headers and open a message only if I find it interesting. I also use folder bookmarks to navigate to folders quickly. I also move messages across folders with keyboard shortcuts. Is it possible to replicate the set-up in Mutt? Can someone share/ point to a sample muttrc file that does the same thing? It would be great if the muttrc file is adequately commented. On a side note, will it also be possible to import my messages from Thunderbird locally? That will save me considerable network traffic (about 2GB data stored locally).

  • No Sound from Shared Media

    - by Travis
    I have a shared media folder that I have all of my mp3's in. When I try to play them using Ubuntu, I get no sound, but the media player (Rhythmbox, Exaile, etc) display that they are playing the file, it looks like everything is playing but no sound. I have checked and rechecked the volume levels of the system and each application and I see no issues. If I move a file to the local drive, it plays just fine. I do sound checks while the file is playing and I get audio (front left, front right) from the test but not from the media file that I am playing. Any help would be greatly appreciated.

  • AdventueWorks Design Patterns Project - Part 1

    - by RonGarlit
    This is the presentation I did tonight at PHILLYNJ.NET.  It is the first in a multi-part of a series on the Applied Design Patterns.   The solution files are working code with design pattern notes in the comment blocks. After the overview and higher level discussions on Enterprise Design Patterns I reviewed the low level Database Access Library of code.  With walk-throughs of the the code and unint test. After that we went through the ProductPhotoConsoleTest Application that performed intergration testing of the DBAccess Class with the AdventureWorks ProductPhoto table extracting the photos and writing them to a file folder. The Demo code and PowerPoint can be obained from this link.  https://skydrive.live.com/?wa=wsignin1.0&cid=29e34e9a8650bb9e#!/?cid=29e34e9a8650bb9e&sc=documents&id=29E34E9A8650BB9E%21151 Please note that I use Visual Studio 2010 Ultimate.  If you have a lesser version the Modeling projects likely will not work or have limited functionality and you should unload that project to prevent warning. Enjoy! --Ron

  • Recovering user files with a Live CD

    - by user33617
    For some reason my bootup isn't working. I get an error akin to "Operating System Not Found". So I tried bootrepair, and that didn't work. So then I decided I would just save my personal files, wipe everything, and reinstall. Except when I go to the /home directory, my username folder isn't there, instead it goes to the Live CD's desktop and file folders. Is there some other error occurring? Is there a way to recover the files?

  • certain files not syncing

    - by Josh
    I have UbuntuOne set up to sync a one folder with a number of subfolders. For some reason some of the subfolders have stopped syncing. Within one subfolder with 6 subfolders in it, some are showing up empty (they shouldn't be) and some are showing up with only some of the files they should contain. I have synced recently, and newer files are showing up in other subfolders. There's just some problem with these particular folders. They are not especially big nor do they have especially big files in them. Thoughts?

  • How to set PcManFm as the default file manager?

    - by JarekJ83
    I think Nautilus is so slow, and I'd like to move to PCmanFM, but didn't find any good tips how to do this in Ubuntu 12.10. I have PCmanFM installed already, and I even changed: $ sudo gedit /usr/share/applications/nautilus-folder-handler.desktop [Desktop Entry] Name=Files Comment=Access and organize files Exec=pcmanfm %U Icon=system-file-manager Terminal=false NoDisplay=true Type=Application StartupNotify=true OnlyShowIn=GNOME;Unity; Categories=GNOME;GTK;Utility;Core; MimeType=inode/directory;application/x-gnome-saved-search; X-GNOME-Bugzilla-Bugzilla=GNOME X-GNOME-Bugzilla-Product=nautilus X-GNOME-Bugzilla-Component=general X-GNOME-Bugzilla-Version=3.2.1 X-Ubuntu-Gettext-Domain=nautilus Still slow Nautilus is default one.

  • HTTP(S) based file server

    - by Michael
    I've got a server running Ubuntu 10.04. I've already gotten openssh for ssh and sftp on it. I've been looking for a web-based (http, or preferably https) file server, perhaps a web-front-end to an (S)FTP server, that allows access to a specific folder, and also allows uploads. It requires user authentication, preferably using PAM. This web-based solution is for users that are not allowed to use FTP software / browser extension and don't have flash / java browser plugins within their corporate environments. So far I have looked into: Webmin: Includes a file manager, however it uses Java, and I'm looking for a plugin-free implementation. Apache2: I was able to set up https and PAM authentication, but the barebone implementation doesn't include file upload (as far as I'm aware of). HFS: Haven't tried it out because it is for Windows/wine only, and I don't want to run it under wine.
