• Sharing Files between Ubuntu 14.04 and Windows 8

  - by Matinn

  I have Ubuntu and Windows 8 installed on one System. I am trying to share files between these two operating systems using an NTFS Partition wich was created by Windows. I don't have trouble accessing the data on this partition from Ubuntu, however if i create a file in Ubuntu, this file doesn't show up when I boot into Windows. Does anyone know how to do this. From what I have read file sharing should work without installing any additional Software, as I am not trying to access the Linux ext4 Partition from Windows.

• Corsair Hydro i series cpu cooler fan control

  - by user214690

  Im relatively new at Ubuntu and have found an answer to basically every single issue ive ever had thru this site... Otherthan this. I have been toying with the idea of a Corsair h80i for my dual boot system (win7/U12.10) and mostly use it in ubuntu. I have done some research on the interweb regarding fan control in linux and nearly ran up short untill I came across this thread: http://ubuntuforums.org/archive/index.php/t-2096166.html And it seems to have worked around it. (altho I have not tested it for myself) Is there any program/library/source that can be used to control the fans without having to MacGuyver it??

• How to modify grub entry for supporting KGDB kernel image?

  - by Nishant

  I am trying to update target m/c grub.cfg file for KGDB setup but while booting the m/c it got hung completely and not asking/waiting for remote gdb connection. Following is the entry which I added:- menuentry 'Ubuntu, with Linux 2.6.32-24-kgdb' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 12878c3b-c553-4b4b-986a-6e32daea3ad1 linux /vmlinuz-2.6.32-kgdb root=/dev/mapper/ubuntu-root ro kgdbwait [email protected]/,@192.168.140.158/ quiet initrd /initrd.img-2.6.32-24-server } I have also compiled and copied /boot/vmlinuz-2.6.15.5-kgdb & /boot/System.map-2.6.15.5-kgdb to target m/c from devlopement m/c.

• "Wireless disabled by hardware switch" after suspend and other hardware buttons ineffective - how can I solve this?

  - by fahadayaz

  I have recently purchased a Novatech nFinity N1410 laptop and am having problems with the wireless, which sudo lshw -C network tells me is Centrino Wireless-N 2230 and using the iwlwifi driver. The problem is that after the device has been suspended, I am not able to get the wireless working again without a restart. The network indicator states that the wireless disabled by hardware switch. Though Fn+F2 is meant to be the wireless switch, xev tells me that the system doesn't see it as anything at all when I press this hardware combination. Also, though the brightness up/down buttons work fine, the volume up/down buttons do not work either. What can I do to fix this? I am running Ubuntu 12.10 with all available updates installed.

• How do I create and link to a database in ASP.NET (Razor) with Visual studio 2013?

  - by Blake

  We have a simple web app, part of which allows users to create accounts and then, hopefully soon, to write blog posts. The user log in system is working great, it utilizes the given .sdf database created when a new project is created. We would like to expand it now to allow for blog data (the title, body of the blog, image posts perhaps, etc). However, I'm unsure of how to add another table to the user database for this purpose - or if that would even be best since it has sensitive information in it. I've been reading blog post after blog post and still can't find anything current on this. All of the articles are for MVC projects or older versions of VS. If someone could point me in the right direction it would be greatly appreciated!

• Disabled WiFi but it keeps re-enabling itself; want it to stay disabled

  - by Mike Uresti

  I have an Alienware X51 desktop with a wireless card, I have it connected via ethernet and want to permanently disable WiFi from ever using itself. When running Windows, I go to device manager and rightclick-disable the Wireless card and that takes care of my problem. Is there a similar method using Ubuntu 14.04? For now, I click on the network icon in the system tray and uncheck 'Enable wifi' but it seems to turn itself back on as I use my computer, I think I have the incident isolated to something with Steam. It seems like after I start the Steam client it always is re-enabled. Hopeful answer: Just disable/remove/block wireless card from ever working.

• Using AWS or Azure, what to do about emails?

  - by Paul

  I'm coming from a background of paying a hosting company X amount per month for a server. This server comes with IIS, WebsitePanel and Smartermail all bundled together. When I create a new domain using WebsitePanel it automatically creates my email account. All I then need to do is configure my DNS to point to the server. I've decided that it is more cost efficient to move to AWS / Azure. Has anyone come from a similar background and moved onto a cloud system? I'd be interested to know what you did regarding emails. So far, these are the suggestions I've seen: Use Google Apps for each domain Use something like Elastic Email to sent out emails Launch a new instance and host an email server on that The first option seems like quite a lot of manual configuration, the second one works good with outgoing emails but what about receiving? Option 3 would make it less cost effective. What is your experience?

• How can I personalize my MacBook Pro Touchpad?

  - by Barkerto

  I'm running Ubuntu 12.04 LTS on a MacBook Pro 5.5. I'm just wondering if there is something that takes all the kinks out of the touch-pad. It works good, but it feels sluggish, double tap works about 75% of the time and sometimes while I it somehow selects something on a different page (although I'm not sure if that has to deal with the touch-pad and not weird laptop bugs for a new LTS) If there are any programs, apps, commands aside from the built in system preferences mouse and track-pad touch-pad menu that allow someone to "optimize" touch-pad potential.

• Gigaom Article on Oracle, Freescale, and the push for Java on Internet of Things (IoT)

  - by hinkmond

  Here's an interesting article that came out during JavaOne which talks about the Oracle and Freescale partnership, where we are putting Java technology onto the Freescale i.MX6 based "one box" gateway. See: Oracle and Prosyst team up Here's a quote: When it comes to connected devices, there’s still plenty of debate over the right operating system, the correct protocols for sending data and even the basics of where processing will take place — on premise or in the cloud. This might seem esoteric, but if you’re waiting for your phone to unlock your front door, that round trip to the cloud or a fat OS isn’t going to win accolades if you’re waiting in the rain. With all of this in mind, Oracle and Freescale have teamed up to offer an appliance and a Java-based software stack for the internet of things. The first version of the "one box" will work in the connected smart home, but soon after that, Oracle and Freescale will develop later boxes for other industries ranging from healthcare, smart grid to manufacturing.

• Broadcom 4365 wireless driver on 12.04 with 3.4 / 3.5 kernel

  - by zaid

  I used this package to install the driver on 3.2 Kernel and it was working perfectly. Unfortunately the system used to freeze randomly with 3.2 kernel so I installed 3.4 kernel, now there is no freezing, the only problem is that my wifi card is not working, I tried to re-install the package, but didn't work. I can see the driver in the "additional drivers" and it say that it is active, but when I execute iwconfig it doesn't show up. I've even tried ndiswraper and that didn't work either. my lspci: 01:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01)

• kernel mem parameter

  - by Ashfame

  As a last resort to my question, I am yet to try the mem parameter of kernel to force it to use the specified amount of RAM. Short Summary - I can only see 3.2GB RAM on a 64bit OS and am not sure ifs a hardware limitation, so wants to try as I found a post on Ubuntuforums. My question is if its ok to play with my resident Ubuntu install or should I be using a live bootable usb? What values do I try (I have 6GB with only 3.2GB being usable) and how to keep it safe? I don't want to burn any of my hardware component at this point of time or make the system unbootable. Running Ubuntu 11.10 with kernel 3.0.0-13-generic

• Ubuntu 12.04 installation freezes at "Detecting File Systems"

  - by user67970

  I am installing Ubuntu 12.04 onto my system, which I am dual booting an already installed version of Windows 7 with. The installation goes fine until what I suppose is near the end of the entire thing, where it is at the page where it scrolls through the features of Ubuntu. At this point, it is saying: Detecting file systems... It will not go past this point, and it has been at this part for an hour and a half. What should I do to fix this? I am new to working with Linux operating systems, so please help!

• Unity-2D ALT F1,F2 custom configuration

  - by LGB

  I have been using Ubuntu since the first public version (I used Debian before). I always have had the policy to change between 8 workspaces with ALT F1...F8. I know this is not a "standard" or so, but I prefer this. It worked well with Unity (Unity-2D, I mean) too, after some configuration. But currently the odd thing happened that after a system restart this is not the case anymore, I am totally lost what could happened. Now ALT F3...F8 works, but not ALT-F1...F2, which just focuses launcher/dash, which is not the thing I want. I know this is the standard meaning of these key combinations (AFAIK) but defining my own key combinations worked before and now it stopped working ... If someone have any idea how to restore my custom configured meaning for ALT F1...F2 too, please share with me. Thanks!

• I Need Help With A Game (Well The API)! [closed]

  - by user1758938

Anyway I'm ok with Java, C# and C++ but I need a good setup (easy to use) with the tools I need to make the game.

I Need A API That Can Do These Things: 3D Rendering Input Sound And If It's Not Too Much To Ask Some Cool Shaders, Dynamic Lighting And A 3D Sound System Im "Ok" If I Have To Use Multiple APIs To Do This But Please Help Me!

• Immutable design with an ORM: How are sessions managed?

  - by Programmin Tool

  If I were to make a site with a mutable language like C# and use NHibernate, I would normally approach sessions with the idea of making them as create only when needed and dispose at request end. This has helped with keeping a session for multiple transactions by a user but keep it from staying open too long where the state might be corrupted. In an immutable system, like F#, I would think I shouldn't do this because it supposes that a single session could be updated constantly by any number of inserts/updates/deletes/ect... I'm not against the "using" solution since I would think that connecting pooling will help cut down on the cost of connecting every time, but I don't know if all database systems do connection pooling. It just seems like there should be a better way that doesn't compromise the immutability goal. Should I just do a simple "using" block per transaction or is there a better pattern for this?

• Can't start x session after updating packages

  - by chaos

  I have recently upgraded to 12.04 and all seems ok except adobe flash plugin doesn't work. But one several days ago when I installed several update packages and rebooted the x session was unable to start and it automatically switches to console 1 for commandline login. What's frustrating is there's essentially no error messages when I click alt+F7 to see what's going on with the x session. There are a bunch of [ok]'s and the last line seems to be something like 'starting x font server' and it just hang there. The closest thing to an error is something like 'stopping system V compatability (*words I can't remember*) ... [ok]'. This is nearly the most frustrating experience I've ever had with linux in the past 10 years. Can anyone help me?

• Could you give me an example of how to attach an object in Deleted state – I keep getting an exception [migrated]

  - by carewithl

  From MSDN : An object in the Deleted state can only be attached when the ObjectStateManager is already tracking the relationship instance. Could you give me an example of how to attach an object in the Deleted state. I tried the following and got "System.InvalidOperationException: The object being attached is in an added or deleted state. Relationships cannot be created for objects in this state". var contact = context.Contacts.First(); Console.WriteLine(contact.Addresses.Count()); // 2 var address = contact.Addresses.First(); context.Addresses.DeleteObject(address); contact.Addresses.Attach(address); // InvalidOperationException thank you

• how to convince other we should move to hadoop?

  - by Ramy

  Everything I've read about Hadoop seems like exactly the technology we need to make our enterprise more scalable. We have terabytes of raw data that is in non-relational form (text files of some kind). We're quickly approaching the upper limits of what our centralized file server can handle and everyone is aware of this. Most people on the tech team, especially the more junior members of the tech team are all in favor of moving from the central file system to HDFS. The problem is, there is one key (most senior, etc.) member of the team who is resisting this change and every time Hadoop comes up, he tells us that we could simply add another file server and be in the clear. So, my question (and yes, it's really subjective, but I need more help with this than any of my other questions) is what steps can we take to get upper management to move forward with Hadoop despite the hesitation of one member of the team?

• Gnome extensions don't work! I've tried everything!

  - by Nightshaxx

  When I go to https://extensions.gnome.org/, and try to install an extension, it clicks on, but nothing happens to my shell. Then, when I reload the page, the slider has turned off. Here are the things I have tried: I tried Chrome, Firefox, and Opera adding http://extensions.gnome.org to my allow plugin list in google chrome and made sure gnome-intigration is enabled I made a new firefox profile and tried installing it I reset my gnome shell settings (How do I reset GNOME to the defaults?) - this link actually broke my system, as now I can't log in to any desktop environment, the only way I can get to Unity, is by logging in to another desktop environment like cinnimon (which doesn't work) , then immediately logging into unity. Whenever I try to just log into unity or pretty much any other desktop environment, it logs in, but then seems to crash, and log out. Sometimes I even get quick glances of the Unity bar before it crashes I tried-re installing gnome None of these methods worked!! Thank you in advance!!
