• How to display lyrics that are stored in MP3-Tag?

  - by Der_Techniker

  How can I achieve that goal? I tried many players - banshee, rhythmbox, amarok, exaile... none of them displays lyrics that are already stored in the mp3. They always try to fetch lyrics from the internet. Interestingly, banshee supports STORING lyrics into the mp3 but not READING - I find that annoying... One player though does it properly - gmusicbrowser. But this piece of software has a so confusing user interface - I don't wanna use it. Any ideas?

• 12.04 reboots rather than shutting down

  - by Luca

  I have a ruvo with a fresh installation of 12.04. When I try and shutdown the computer reboots. Until I upgraded (by doing a fresh install) I ran it with Ubuntu 10.04 and I didn't have this issue. I have tried sudo shutdown -h now sudo shutdown -P now sudo init 0 sudo poweroff All of these cause a reboot. I have added acpi=norq to my grub file as suggested by someone in the first post below. This is being used as a mythtv frontend and I would like the power button to shut it down. I have modified the button to perform a shutdown -h now, but this too causes a reboot. I have studied the posts below and tried some of these ideas, but with no luck so far. Why do I get a reboot instead of a shutdown? Ubuntu 12.04 not shutting down properly Stuck on reboot and shutdown Shutdown does not power off computer

• Ubuntu VPN server setup

  - by framberries

  I followed the instructions that the answer on this thread gave, Easiest way to setup Ubuntu as a VPN server. However, I cannot get it to work. When I try to connect to my network, it just says the server cannot be reached. I setup the remote IP options (which I uncommented) to be 10.0.2.2-100. My router serves out 10.0.1.2-250. I also have users setup, but they are uncommented as well. I assume you need to uncomment them?

• eth0 not working on startup

  - by user4106

  Hi to all, This might sound strange but, working with my Lubuntu 10.04 i've experienced troubles when connecting to my eth0 newtwork. After some googling, i've found out that by writting in the CLI the following command: mii-tool eth0 -F 10baseT-FD and activating the eth0 in the toolbar (by clicking "activate eth0") everything works just fine. Well, up to now, i did not have any problem, because every time i turned on the computer i had to do this, but it was very little effort.But now, i would like to use the machine as a file server, accesing it by ssh, without monitor or keyboard. So, i won't be able to make this actions, and can't do this at startup because mii-tool needs root permissions. So, the question is: Do you know what does that command do, and how can id make that change permanent? Or do you know any other solution for my problem? I hope i was clear! If not, tell me and i'll try to be as clearer as possible. Thanks in advance!

• Preparing for Interview: I feel like, I wanna start coding all data structures again.... Is it a right way to start?

  - by howtechstuffworks

  I started preparing for my interview. I will be graduating this May. Right now, I am doing an internship in an product based company, so I did my fair share of preparation. The thing is, whenever, I try to do something, I always think that I should start everything from page 1. It is sometimes not at all helpful.... For example, reading a programming book from page 1 is not going to helpful, as I never completed one and always stopped half way through or rushed through towards deadlines. I am facing a similar situation now. I feel like, I wanna start coding all data structures from first(I attempted and finished atleast 6-7 last fall, preparing for interview). Now I feel like, I wanna code everything from first, instead of attempting something new.... I am not quite sure, what this is, but this is the way I have been..... LOL

• Ubuntu 14.04 not booting before Windows 8.1

  - by user280244

  I try too boot my computer into Ubuntu, but I end up having to manually select Ubuntu from the devices menu, even though it was supposed to boot first. Instead Windows 8 boots up like Ubuntu isn't even there! And GRUB works just fine when Ubuntu is selected in the boot device menu. (How else am I on?) I tried using EasyBCD but kept getting errors from the windows boot manager. And just in case it helps, during installation of Ubuntu it didn't recognize windows 8, and I had to resize and install manually. Anything I can do? Notes: EVERYONE!!! GRUB WORKS PERFECTLY!!! IT IS AN ERROR IN THE HP BOOT MENU AS I HAVE PREVIOUSLY SAID!!! PLEASE DO NOT GIVE ME ANSWERS FOR GRUB EDITS IN THE FUTURE!!! Here are my specs: PC type: HP 2000-2d49WM Notebook PC RAM: 4GB Swap: 2GB Processor: AMD E-300 Vision 1.3 GHz x2 BIOS Edition: N\A Until further notice

• Main class passes dbConn obj to all its services, I need to change the dbConn for one of its services. - suggestion for design pattern

  - by tech_learner

  There is this main class and there are several services ( which uses db connection to retrieve data ) These services are initialized in the main class db properties are obtained from the property file and then dbconnection is opened by calling a method dbOpen() written in the main class and the resultant connection object is set to the service objects by iterating through the list of services and by calling setConnection method on the service note: that the services are instantiated in the main class and the main class is not a superclass for services. I also need to mention that there is this recycle db connection scenario only main class is aware of. /** connects to DB, optionally recycling existing connection), * throws RuntimeException if unable to connect */ private void connectDb(boolean recycle) { try { if (recycle) { log.status( log.getSB().append("Recycling DB Connection") ); closeDb(); } openDb(); for ( int i = 0 ; i < service.length ; i++ ) { service[i].setConnection(db); } } One of the service needs to use a different database, what is the best design pattern to use?

  I'm having problems both with bluetooth and wifi, my pc is a Lenovo B5400.

What are the commands I can use to see what's going on? Thank you in advance

• 6 Alternatives to iGoogle For Personalized Homepages

  - by Chris Hoffman

  iGoogle has less than a year to go before it’s shut down for good on November 1, 2013. While Google seems to think that iGoogle isn’t necessary anymore, there are other services waiting to take its place. Google says that “with modern apps that run on platforms like Chrome and Android, the need for iGoogle has eroded over time.” If you disagree, try one of the services below.

• After installing ubuntu, all my partitions are gone. Boot-repair log

  - by user211079

  I have an HP Pavilion Sleekbook that came with windows 8 pre-installed. I had trouble dual booting after installing ubuntu, so I disabled safeboot on bios and proceeded to try boot-repair, nothing happened. No dual boot yet. So I tried to reinstall ubuntu, but without the manual partitioning. So I chose to erase ubuntu 13 and reinstall it. Instead it deleted all my HP recovery partitions and windows as well. Here is the log of boot-repair. http://paste.ubuntu.com/6354919/ Gparted and fdisk only show one partition: /dev/sda1 I am wondering if you could suggest any way of recovering my windows partition and have a working windows 8 again? I need some information there with urgency. If you could help me I will be welcome. I am desperated. Thanks

• What is the difference between Indicator Plugin and Notification Area?

  - by Angelo

  I don't really understand why Ubuntu has two "notification area" style things that seem to serve the same functionality. I can't use only one because some of the programs seem to only work with Notification Area (e.g. Orage) and some only work with Indicator Plugin (e.g. indicator-sound). I noticed that the network manager applet will prefer to insert itself into Indicator Plugin and if that isn't available, try Notification Area. I don't understand why we have/need both? Is it normal to keep both running?

• Ubuntu 12.04 x64 doesn't boot anymore after a power failure

  - by Felix

  I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive?

• Cannot access my own web page

  - by enflam3

  I am developing, learning and experimenting with php,html,javascript,flash and so on. Having web hosting and all of the cpanel, phpmyadmin and other utilities. One day, while updating information, connection between my computer and website just went down. I found out that it is only from this computer, where I cannot access anything. I don't know what is the reason I cannot access website, however this is what I have checked so far: Everything else opens normally, having problem only with my page. Cannot access FTP,cpanel or any kind of information related to the domain and hosting ipconfigs detects IP, but shows request timed out (so its not browser related) Turned off Firewall,AV, Rebooted computer Cleared caches,temp,cookies,histry with CCleaner Checked connectivity with both (wired,wireless) networks ISP has dynamic IP that has been changed about 3 times since issue Checked host file I am out of ideas and understanding what could cause this kind of issue, however couple minutes ago, found out that everything works with proxy server (when adding IP and port to the browsers) Can someone point out what should I check or try to get rid of this problem?

• Creating a interactive grid for puzzle game

  - by Noupoi

  I am trying to make a slitherlink game, and am not too sure how to approach creating the game, more specifically the grid structure on which the puzzle will be played on. This is what a empty and completed slitherlink grid would look like. The numbers in the squares are sort of clues and the areas between the dots need to be clickable. http://i.stack.imgur.com/U1kXn.gif http://i.stack.imgur.com/RMwiv.gif I would like to create the game in VB .NET. What data structures should I try to use, and would it be beneficial using any frameworks such as XNA?

• 12.04 freezes on install

  - by CHris

  I'm new to ubuntu and can't for the life of me understand how to get around this issue. I'm having a problem where when I insert the boot disk that i burned for 12.04, it loads and gives me the language option and select an installation type, i select either try ubuntu / install ubuntu and it begins to load. Then after about 5 mintues of the purple screen with the dots under the UBUNTU it freezes the whole computer, and the only way to get out is to turn off the laptop with the power button. I have read previous threads saying people had similar "freezing" issues including ones that mention my model of laptop, HP Pavillion DV1000. But it appears their problems are post installation and relate to their wireless cards. I have tried changing the boot options (F6) and I am totally stuck. Can anyone shed any light on to this issue? Thanks in advance.........

• Kubuntu? What is that..?

  - by Hayden Win

  Okay so when i was running the Ubuntu installer i found something called "Desktop Interface". It was apparently selected as Ubuntu. I looked at the full set of options and found out that there's Kubuntu there! I want to know what Kubuntu is. If i can get it on Virtualbox then how? I want to try out Kubuntu but i don't want to over write my Ubuntu with Kubuntu. [ Because of Ask Ubuntu's "This question body does not meet our etc etc" i have been forced to include this extra text ]

• Dash Home pane disappears when clicked

  - by okramer

  I am having a problem with Dash Home. When I launch it from my launcher bar, I get the translucent search pane (like I always did, even when it worked). However, if I try to click anywhere in the dash pane, the pane disappears and the action goes to the underlying window, as if the dash pane was not really there. I can type in the search field and Dash responds with matches, but I can't do anything with the results, since when I click it just disappears. I'm running Ubuntu 12.04. Any ideas?

• How long till HTML5 canvas becomes a viable game development platform?

  - by Shouvik

  So I have been working on web application. So invariably what it boils down to is making simple games which were previously based on flash or openGL. Now I know apple was moving away from flash because its proprietary unlike their stance that its got "pathetic performance"! Not true, try playing a canvas game, I can assure you at any point of time (including when its idle) it will use up a fair bit of processing power just to redraw the UI. Now I do understand that this is my fault because when the game is not active I should not be redrawing the canvas, but honestly its a lot of work and I suppose there should be libraries which should be able to assist me with that! So, how much will it be before I see a decent canvas library which handles these "tiny" issues for me? I can't honestly expect Steve Jobs to be doing anything more for HTML5! I someone knows of a good library, I am all ears...! :) PS: I use mootools and am presently using Mootools Canvas Library.

• Chinese bots in my forum

  - by TdotThomas

  I have a small community forum that doesn't really get posts or any real traffic. The only thing that happens on the regular is bots with Chinese IPs signing up gibberish usernames. Most bots don't make it past the captcha but some do. I try to stay on top of this by banning IPs and ranges of IPs but it doesn't really seem to help. The bots never post anything so what are they doing? Should I be worried? Should I keep banning IPs or is it futile?

• How can I prevent people from looking at a listing of files in parent directory if I haven't uploaded index.html? [closed]

  - by LedZeppelin

  Possible Duplicate: How to restrict the download of all files in a folder? I haven't uploaded index.html or index.php to my root directory. How can I prevent people from looking at a listing of files in parent directory? http://oi56.tinypic.com/sc739e.jpg Also, is it possible for people to obtain a list of all the files in the root directory once I upload index.html? I'm currently using .htaccess and htusers to prompt someone to enter a username and password when they try to access any file in the root directory. This may sound like a weird request but would it be possible to have them come to the site (without an index.html) and just have them not see the files? All it would say on the page would be the following: Index of/ Apache Server at mysite.com Port 80
