  • Which tools helps to start Ubuntu GUI when boot?

    - by Vimal Kumar
    I am on the way to create a Live CD from scratch. I used Virtual Box for this purpose. I installed Ubuntu base from ubuntumini.iso and installed gnome-shell. And installed Remastersys and created a backup.iso. Burned in a CD and boot from a PC. It end in CLI. Not lead to GUI. I tried the same ISO in VirtualBox. But it work properly there. I think I missed some packages which help to start GUI. Can you help me to identify the packages missed to include in the CD?

  • Oracle Virtualization Friday Spotlight - November 8, 2013

    - by Monica Kumar
    Hands-on Private Cloud Simulator In One Hour Submitted by: Doan Nguyen, Senior Principal Product Marketing Director My aeronautics instructor used to say, "you can’t appreciate flying until you take flight." To clarify, this is not about gearing up in a flying squirrel suit and hopping off a cliff (topic for another blog!) but rather about flying an airplane. The idea is to get hands-on with the controls at the cockpit and experience flight before you actually fly a real plane. After the initial 40 hours of flight time, the concept sank in and it really made sense.This concept is what inspired our technical experts to put together the hands-on lab for a private cloud deployment and management self-service model. Yes, we are comparing the lab to a flight simulator! Let’s look at the parallels: To get trained to fly, starting in the simulator gets you off the ground quicker. There is no need to have a real plane to begin with. In a hands-on lab, there is no need for a real server, with networking and real storage installed. All you need is your laptop The simulator is pre-configured, pre-flight check done. Similarly, in a hands-on lab, Oracle VM and Oracle Enterprise Manager are pre-configured and assembled using Oracle VM VirtualBox as the container. Software installations are not needed. After time spent training at the controls, you can really appreciate the practical experience of flying. Along the same lines, the hands-on lab is a guided learning path, without the encumbrances of hardware, software installation, so you can learn about cloud deployment and management.  However, unlike the simulator training, your time investment with the lab is only about an hour and not 40 hours! This hands-on lab takes you through private cloud deployment and management using Oracle VM and  Oracle Enterprise Manager Cloud Control 12c in an Infrastructure as a service IaaS model. You will first configure the IaaS cloud as the cloud administrator and then deploy guest virtual machines (VMs) as a self-service user. Then you are ready to take flight into the cloud! Why not step into the cockpit now!

  • Sound card not detected in 13.04

  • How should I determine direction from a phone's orientation & accelerometer?

    - by Manoj Kumar
    I have an Android application which moves a ball based on the orientation of the phone. I've been using the following code to extract the data - but how do I use it to determine what direction the ball should actually travel in? public void onSensorChanged(int sensor, float[] values) { // TODO Auto-generated method stub synchronized (this) { Log.d("HIIIII :- ", "onSensorChanged: " + sensor + ", x: " + values[0] + ", y: " + values[1] + ", z: " + values[2]); if (sensor == SensorManager.SENSOR_ORIENTATION) { System.out.println("Orientation X: " + values[0]); System.out.println("Orientation Y: " + values[1]); System.out.println("Orientation Z: " + values[2]); } if (sensor == SensorManager.SENSOR_ACCELEROMETER) { System.out.println("Accel X: " + values[0]); System.out.println("Accel Y: " + values[1]); System.out.println("Accel Z: " + values[2]); } } }

  • Testing web applications written in java

    - by Vinoth Kumar
    How do you test the web applications (both server side and client side code)? The testing method has to work irrespective of the framework used (struts, spring web mvc) etc. I am using Java for the server side code, Javascript and HTML for the client side code. This is the sample test case of what I am talking about: 1. When you click on a link, the pop up opens. 2. Change some value in the pop up (say a drop down value) and it gets saved in the DB. 3. Click the popup again, you get the changed values. Can we simulate this kind of thing using unit test cases? Is JUnit enough for this?

  • How to use unused space in ubuntu

    - by Ravi.Kumar
    I installed ubuntu on my machine with only 80 GB of memory anticipating that I will remove it later but now I want to keep it forever (until I am frustrated with linux). I have 500 GB in my machine and now I want to use that raw 420 GB of space. How I can I do that ? with "space/memory" I am referring to secondary memory not Ram. Here is output of : sudo fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000dcb77 Device Boot Start End Blocks Id System /dev/sda1 * 2048 136718335 68358144 83 Linux

  • Nginx ssl redirection of images

    - by krishna raj
    Hi. I am trying to set up nginx as reverse proxy for a tomcat server using SSL connection. I want the client's browser to load my tomcat application when nginx reverse proxy's IP is called from client's browser. My tomcat application's address is 192.168.25.25 and nginx proxy's address is 192.168.25.50 In my nginx.conf file i have added these lines # location / { proxy_pass https://192.168.25.25:443/myapp/; proxy_redirect https://192.168.25.25/myapp/ https://192.168.25.25/; } # Some of the images in my application is stored at 192.168.25.25/images/ . Now these directories cant be accessed as the proxy_pass is set to 192.168.25.25:443/myapp. Is there way to access images directory also without changing proxy_pass ? Thanks in advance.

  • Core Audio sound driver has an error

    - by Raj More
    I have been using Virtual DJ on my machine. The setup is where I want audio to play over the headphones and use a USB sound card to play audio into my headphones so I can listen to music before I play it for everybody. However, the last time I tried, I got an error message saying "Error in the sound driver of Core Audio. Your sound card is probably not connected, or the settings are incorrect". If I use the headphone by themselves, the USB sound card by itself, or my speakers by themselves, they all work individually. How do I go about figuring out what's wrong here?

  • Instant database snapshot

    - by raj
    My product uses oracle 9 database in its backend. every week the new release of the product is launched which will want to fire some DML, DDL queries to the database. I usually test the product release in a dummy database before applying it in the main database. I create a database dump using exp command, then import them into dummy database using imp. then i test the product in the dummy database and checks if there are any errors. This exp and imp takes about 3 hours to complete. Is there any alternative as : instant snapshot of the live database (which will be independent of the live one)? or is there any option to keep dummydatabase in sync with the originl database always. Yhis can be done by making the product firing DML&DDL queries to both the databases.. but this will be a HUGE performance problem.. how can i overcome this?

  • Blocking ICMP outgoing requests only in eth1

    - by Raj
    I am creating a NAT with iptables: Computer A: eth0 (dhcp) + eth1 (static ip 192.168.0.1 - gateway) Computer B: eth1 (static ip 192.168.0.2, using Computer A as gateway) I know how to block ICMP outgoing requests (-A OUTPUT -p icmp --icmp-type echo-request -j DROP), but that would block ICMP requests from Computer A, but not from Computer B (in fact, only for Computer A - Computer B can keep doing those). I tried with the same command, but adding -o eth1, but that does not block at all. Any idea?

  • How to add delay in autologin

    - by raj
    I enabled autologin in my system (CentOS 6.2) for that I edited this file /etc/gdm/custom.conf In that I entered this code [daemon] AutomaticLoginEnable=true AutomaticLogin=test Here test means one account name, for that account autologin is working but the problem is not possible to logout. That is because everytime while I logout it will go to gdm(graphical display manager) and there it Again checks for account test. It is available right so it will again login to same account. Here I want add delay, that means it should wait for sometime, If no one login to any other account, then only test account will log. how to add delay?
