What is NLP Neuro means nerves or nervous system. Which is the physical as well as mental component of our body. Linguistic is the language we use to communicate with others. It's also the internal communication we do with ourselves in the form of thoughts, feelings, conversations. We already know what programming means. Think of NLP as a program which gives us control on our own system OS as you many say. Now why do we need control on ourselves, don't we already have it. Well yes, that's what we always like to think. Let's take an example, I know for a fact how important it is for me to lose weight, if I don't I will eventually have many problems when I grow old. But what happens when I go out on Friday night with my friends, I see yummy food, drinks and I immediately give up the thought of going lite on my food. If I had a program to control myself, I would be able to make changes in myself which are immediate and effectively. The reason why we don...

Lot of people are exploring the Raspberry PI as the preferred automation device platform and I wanted to share my first impression on the setup and installation of the device. Raspberry Pi 3 is the third generation Raspberry Pi from Element14 https://www.raspberrypi.org/products/raspberry-pi-3-model-b/ First thing you would need are a bunch of hardware, most of them are easily available on Amazon. I have listed my shopping list. Raspberry Pi 3B - Rs 2999/- link Sandisk SD Memory Card - Rs 689/- link Breadboard - Rs 80/- link LED and other components - Rs 450/- link Female to Female Jumper cable - Rs 138/- link Male to Female Jumper cable - Rs 118/- link Raspberry pi 3 Model B case - Rs 365/- link Power Supply - Rs 879/- link 8 Bit SMD LED Array with connector cables - Rs 99/- link Total cost = Rs 5817/- For operating system I have selected Raspbian which is the official supported OS for Raspberry Pi. Task 1: Installing Raspbian to the SD memory card ...

I wanted to install Oracle Enterprise Linux 6 on my ASUS G75V laptop and encountered some issues. 1. Secure boot If you try to boot from a bootable usb drive, or a bootable cd/dvd you will get "Signature" error and the installation will not start, its because the BIOS has a setting called as Secure Boot, which does not allow unsigned software to be installed. You can bypass this by going to BIOS setup and disable the Secure Boot. Read more about Secure Boot  http://www.webopedia.com/TERM/M/microsoft_secure_boot.html 2. X Window start to failed Because the Asus has NVEDIA Graphics card the GUI based installation fails to start and the installation starts in the console mode. The implication is the Linux installed will have minimal drivers and is n

Scenario : I have a Windows 8 (Host) laptop on which I am running two OEL6U3 (Guest) machines in a Virtual Box. I want to have a shared mount between the two Linux machine which will allow me to read/write from both the machines concurrently. Its a very common scenario for a High Availability Environment. Virtual Box provides a facility of creating sharable VDI disks which can be mounted on multiple machines, but it doesn’t allow concurrent read/write access from multiple machines. If you are installing RAC database then its still achievable, because ASM will provide the feature of concurrent read/writes, but if you want to install a WebLogic cluster with High Availability the recommended approach would be to have a Shared Mount. Step to create a shared nfs mount is fairly simple. I am using a WD My Book Live, and will mount the Public folder as shared mount 1. Get the hostname/ip of the WD device. 2. On the Linux Machine 1 create the folder where you want to mount the nfs ...

If you wan to create a shared drive in Oracle Virtual Box then follow the steps below: 1. Create the shared disk cd "D:\VirtualBox VMs\oracle_shared" "c:\Program Files\Oracle\VirtualBox\VBoxManage" createhd --filename weblogic_shared.vdi --size 20480 --format VDI --variant Fixed 2. Attach the shared drive to the Linux Machine 1 "c:\Program Files\Oracle\VirtualBox\VBoxManage" storageattach OEL6U3-WebLogic-Node1 --storagectl "SATA" --port 1 --device 0 --type hdd --medium weblogic_shared.vdi --mtype shareable 3. Attach the shared drive to the Linux Machine 2 "c:\Program Files\Oracle\VirtualBox\VBoxManage" storageattach OEL6U3-WebLogic-Node2 --storagectl "SATA" --port 1 --device 0 --type hdd --medium weblogic_shared.vdi --mtype shareable 4. Make the disk sharable "c:\Program Files\Oracle\VirtualBox\VBoxManage" modifyhd weblogic_shared.vdi --type shareable Note: This will just create a shared disk ...
