• how to access samba shares via nat?

  - by HSM

  I have setup a virtual machine in Virtual Box and installed a Samba Server. I changed the guest operating system's NIC from Bridged to NAT for a reason that I can't remember. I then added a additional NIC in "host only adapter" mode. The Windows host OS now can access the Ubuntu 10.10 virtual server via the Host Only NIC. However, I can not access the Samba server running on the Ubuntu guest OS. I am not sure what to do now. How can I get the widows Host OS to access the Guest OS' samba server.

• copy & paste in VirtualBox remote console when running headless

  - by katsumii

  One can run VirtualBox guest in "headless" mode and access it using Remote Destkop Protocol(RDP) client.This is typical when VBox server is installed on Linux/Solaris where X-window stuff is not installed and users useWindows to access the VM.So, one can install OS into VBox guests using Remote Desktop client.(e.g. mstsc.exe)Here's the setting. One lesser known feature here is that you can copy&paste into and out-of VM guest and your client.Apparently, "VMware Workstation" still doesn't support it. VMware Workstation Documentation CenterYou cannot copy and paste text between the host system and the guest operating system

• Why didn't IE8 support border-radius, evil or ignorance?

  - by Mark Rogers

  When I think back to the time of the release of IE7, I was surprised that there wasn't border-radius support. It seems like an obviously great idea to have a css-property name for rounded corners, which can potentially make a site look less like it came from the computer stone-age. Finally, today we have IE9 and Microsoft finally decided to play ball with the rest of the world. But the question remains, why didn't Microsoft bother to support border-radius in IE8? The problem probably became obvious to the company as the growing chorus of complaints from web developers got louder after the release of IE7. Was the company so isolated or in group-think mode that they were blind for that many years? Or did Microsoft have some additional motive to suppress the border-radius property?

• Ubuntu will not start due to full partitions

  - by mike

  I left my computer downloading all the night and I did download 35 GB of movies (legal ...). I restarted the computed in the morning then I booted in my encrypted Windows partition for my work. I have left my computer downloading 35GB of files and when I restarted in the morning, I booted Windows. When I tried to access Ubuntu, it failed to boot and in low-graphic mode told me that it won't boot because the partition is full. I tried rescue and it reported 0 MB free. I also cannot delete files with sudo rm as all are impossible due to a read-only file system. I can mount it in Windows but there is a "write protection" there, also. Should I try a live USB?

• How do I fool 12.10 to think it uses Unity2d in order to get the resolution my screen can use?

  - by Konstapel Kask

  On a laptop (model older) I have two screens (one built in, one external). I wish to use them both at the same time, but the settings app complains: Requested size (2944, 1080) exceeds 3D hardware limit (2048, 2048). You must either rearrange the displays so that they fit within a (2048, 2048) square or select the Ubuntu 2D session at login. The problem though, Unity 2D has been discontinued. I have forced Ubuntu to render Unity in 2D mode (with the help of echo export UNITY_LOW_GFX_MODE=1 >> .xprofile in accordance to this askubuntu post. But the error message still remains. How can one get the resolution that my computer supports? Or, how can I assure Ubuntu that it truly does use a 2D session?

• Regain Sudo rights after removing from admin group

  - by berkes

  Hello, I accidentally removed myself from the admin group when editing the user. Now I can no longer use sudo. The error says: ber is not in the sudoers file. This incident will be reported. I booted up in rescue mode, but, when going into root prompt, it asks me for the root password. I don't have one, and providing with my own (first and only ubuntu-user) password, it won't allow entrance. My harddisk is encrypted, but only the /home/user part, not the entire disk, afaik. What can I do?

• ANTLRWorks 2: Early Access Preview 10

  - by Geertjan

  I took a quick look at how the ANTLRWorks 2 project is getting on... and discovered that today, March 23, the new early access preview 10 has been released: http://www.antlr.org/wiki/display/ANTLR4/1.+Overview Downloaded it immediately and was impressed when browsing through the Java.g file that I also found on the Antlr site: (Click to enlarge the image above.) On the page above, the following enhancements are listed: Add tooltips for rule references Finally fixed the navigator update bug Major improvements to code completion Fix legacy mode Many performance and stability updates I've blogged before about how the developers on the above project consider their code completion to be "scary fast". Some discussions have taken place about how code developed by the ANTLRWorks team could be contributed to the NetBeans project, since NetBeans IDE and ANTLRWorks 2 are both based on the NetBeans Platform.

• Color indication in Visual Studio 2012

  - by Jalpesh P. Vadgama

  This post will be a part of Visual Studio 2012 series. Before some days Microsoft has released the release candidate version of Visual Studio 2012. Today I got installed Visual Studio 2012 and once I loaded the visual studio 2012 first things I noticed that there is purple color blank strip is there at bottom. After doing some R and D on internet I have found that it is used for the different indication. The purple color indicates that there is no project loaded now. Once you open the project this line will be of blue color like below. Once you run and F5 and debug it, the color will change to orange like below . Isn’t that great? A simple color indicator for each mode in visual studio 2012. Stay tuned for the more. I am going to put some more post about Visual Studio 2012. Till then happy programing

• How to adjust TouchPad edge scroll area in Ubuntu?

  - by MikeVB

  I have an Acer Aspire that I have dual booting XP and Ubuntu. On the Windows side, the driver allows you to set how close your finger has to be to the edge of the TouchPad before it goes into scroll mode. In Ubuntu I don't have the option (at least in the GUI) to change the scroll area on the pad. Is there a conf file or other way to change this? I'm constantly getting into the scroll area during normal usage. I would like to leave it on without losing so much pad area to the scroll feature.

• Cannot mount Android phone and sync with Banshee

  I can't get my LG Optimus One to sync with Banshee. I read somewhere that the root needs to have an empty file called '.is_audio_player'. I did that and it still doesn't mount. I ran dmesg however and it appears that the card is unmounting before I even have a change to run Banshee.

• How can I recover from a frozen app when connecting over VNC

  - by Pablojim

  I have a htpc running 10.10. It has no keyboard or mouse attached, so I connect over vnc for administration and manual tasks. This usually works fine but every so often an app running in fullscreen mode crashes. All I want to be able to do is kill this app from VNC. Is there a keyboard shortcut to do this that will preserve the VNC connection? If I use CTRL + ALT + F1, I see the terminal but can no longer control it from VNC. Trying to return to the desktop doesn't work either? Any easy process I can follow?

• Wubi downloaded and installed 64bit 12.10 on my 32bit netbook

  - by Troy

  I downloaded the Wubi installer on my atom N450 netbook. When I started up Ubuntu I got an error that read failed to change the mode of /ect/passwd- to 0600. Then while it booted it froze and several strange characters filled the screen. Finally it loaded it ran pretty slow, and I could connect to my router, but not to the internet. Ping 8.8.8.8 showed no server found. So I checked the about computer and it said I was running the 64 bit installation. Now I know that my computer has a low power 32 bit chip and even the Ubuntu iso download suggested a 32 bit installation. So I went to double check and see if I just missed the option for a 32 bit Wubi install and I did not. There was no option. Is there any way to download a 32 bit version of 12.10 through the Wubi?

• Xubuntu, LXDE, USB Booting

  - by Kosciak

  Welcome, My problem appeared today - I was using Xubuntu for a long time, but find out that LXDE should be faster than Xfce, so I installed it. After installing I followed tutorial for removing Xfce, cause disk in my computer is very small and I wanted to release some free space. I used command from this tutorial: How to remove xubuntu-desktop? but instead of remove I entered purge command… and rebooted at the end. And I uninstalled whole my things. The problem is in installing system again - it's old Sony Vaio laptop (PCG-GR250) and I have broken CD-DVD drive. It's possible to boot from USB? I can access recovery mode, will this help me? Please answer fast, because it's my brother computer, and his going to kill me if I won't fix this fast :(

• Profiling Startup Of VS2012 &ndash; YourKit Profiler

  - by Alois Kraus

  The YourKit (v7.0.5) profiler is interesting in terms of price (79€ single place license, 409€ + 1 year support and upgrades) and feature set. You do get a performance and memory profiler in one package for which you normally need also to pay extra from the other vendors. As an interesting side note the profiler UI is written in Java because they do also sell Java profilers with the same feature set. To get all methods of a VS startup you need first to configure it to include System* in the profiled methods and you need to configure * to measure wall clock time. By default it does record only CPU times which allows you to optimize CPU hungry operations. But you will never see a Thread.Sleep(10000) in the profiler blocking the UI in this mode. It can profile as all others processes started from within the profiler but it can also profile the next or all started processes. As usual it can profile in sampling and tracing mode. But since it is a memory profiler as well it does by default also record all object allocations > 1MB. With allocation recording enabled VS2012 did crash but without allocation recording there were no problems. The CPU tab contains the time line of the application and when you click in the graph you the call stacks of all threads at this time. This is really a nice feature. When you select a time region you the CPU Usage estimation for this time window. I have seen many applications consuming 100% CPU only because they did create garbage like crazy. For this is the Garbage Collection tab interesting in conjunction with a time range. This view is like the CPU table only that the CPU graph (green) is missing. All relevant information except for GCs/s is already visible in the CPU tab. Very handy to pinpoint excessive GC or CPU bound issues. The Threads tab does show the thread names and their lifetime. This is useful to see thread interactions or which thread is hottest in terms of CPU consumption. On the CPU tab the call tree does exist in a merged and thread specific view. When you click on a method you get below a list of all called methods. There you can sort for methods with a high own time which are worth optimizing. In the Method List you can select which scope you want to see. Back Traces are the methods which did call you. Callees ist the list of methods called directly or indirectly by your method as a flat list. This is not a call stack but still very useful to see which methods were slow so you can see the “root” cause quite quickly without the need to click trough long call stacks. The last view Merged Calles is a call stacked view of the previous view. This does help a lot to understand did call each method at run time. You would get the same view with a debugger for one call invocation but here you get the full statistics (invocation count) as well. Since YourKit is also a memory profiler you can directly see which objects you have on your managed heap and which objects do hold most of your precious memory. You can in in the Object Explorer view also examine the contents of your objects (strings or whatsoever) to get a better understanding which objects where potentially allocating this stuff.   YourKit is a very easy to use combined memory and performance profiler in one product. The unbeatable single license price makes it very attractive to straightly buy it. Although it is a Java UI it is very responsive and the memory consumption is considerably lower compared to dotTrace and ANTS profiler. What I do really like is to start the YourKit ui and then start the processes I want to profile as usual. There is no need to alter your own application code to be able to inject a profiler into your new started processes. For performance and memory profiling you can simply select the process you want to investigate from the list of started processes. That's the way I like to use profilers. Just get out of the way and let the application run without any special preparations.   Next: Telerik JustTrace

• Ubuntu Server 12.04 Screen Resolution "Out of Range"

  - by Alastair Mackie

  I'm fairly new to ubuntu and have just installed Ubuntu Server 12.04 on a spare machine to experiment and play with! The installation went without problem, however whenever the OS boots the monitor displays a an error message saying the resolution is "out of range" and i can't see to do anything - i can wait as long as i like, but nothing appears. Ubuntu is the only OS installed so bypasses GRUB on boot, although the GRUB screen is also out of range if forced on startup. I can access a shell from the recover mode and i can get at a terminal through a LiveCD of the Desktop version but have had little luck with either. I've been trying to figure this out for days and i'm at a total loss. Any thoughts?

  When I am writing C code on the vi editor, I am not able to use the backspace keys or my arrow keys to delete or navigate through lines. Some unexpected special characters occur on the screen that is on middle of my code and I am not able to delete them also. If I use my delete key, the whole code gets deleted. I have tried both insert mode using 'i' and 'a'. I am able to manage this situation for C programming by using the text editors but when I am creating LeX and yacc programs, I find this awkward. Can you please help me with this?
