  • 13 MP camera with optical image stabilization, HDR, and LED flash

My setup:

Laptop with Ubuntu 14.04LTS  and Nexus 4.

I also assume you are comfortable with the command prompt. You need to run some commands from terminal.

If you are already running Android 5.0, you can skip Step 1 and go directly to Step 2 to root your device. In my case, I didn’t wait for the OTA update, but if you prefer to play it safe, get the Android 5.0 update and then start.

Pre-Preparation.

Make sure your laptop is charged or plugged into the power and your phone is charged too.

Take a full system backup, because these steps wipes the Android clean.

And ensure your laptop doesn’t go into suspend mode while you do this.

Now install a few packages:

sudo apt-get install android-tools-adb

sudo apt-get install fastboot

sudo add-apt-repository ppa:phablet-team/tools
sudo apt-get update
sudo apt-get install phablet-tools

Step 1: Installing Android 5.0

NOTE: This will wipe the system clean so if you haven’t backed up, go and back up first.

Download the correct file from the Google site:

https://developers.google.com/android/nexus/images

For Nexus 4 it is called.

occam-lrx21t-factory-51cee750.tgz

Now extract the files, it will show you a directory

occam-lrx21t

Change to this directory occam-lrx21t

Now boot into the bootloader, remember this step as you will need to do it a few times.

adb reboot bootloader

If it’s not able to find the device,  you can boot manually.

For nexus 4, while holding the volume button down, press the power button.

Now unlock the device with the following command.

fastboot oem unlock

Now flash the Android 5.0 Image by running this command from the directory above.

./flash-all.sh

After a few minutes, On the phone you will see a new boot up logo for Android 5.0. this will take a few minutes to complete. Grab a coffee or your favourite beverage.

Once this is complete, wait you still have to root the device.

wait, don’t do much on your android, as the unlock process may wipe your data!

Step 2: Rooting Android.

Download the rooting script from chainfire: http://download.chainfire.eu/297/CF-Root/CF-Auto-Root/CF-Auto-Root-mako-occam-nexus4.zip

When you scroll down, you see the actual link to download.

This will download this file: CF-Auto-Root-mako-occam-nexus4.zip

Extract this directory, change to this directory.

Now boot into the boot loader with your preferred method. I used volume down button + power on.

Now type these commands.

chmod +x root-linux.sh 
./root-linux.sh

Step 3: Installing MultROM manager

Find the app in Google Play and Install.

Start the app. This will ask you to install 3 things, go ahead and install.

Screenshot_2014-11-23-23-52-01

It will also boot into recovery mode.

Once its done, it will reboot and start android.

Now start the MultROM manager again.

You should see the option to install Ubuntu Touch.

Screenshot_2014-11-23-23-55-30

Step 4: Installing Ubuntu Touch

If you want demo files, select the -demo

you can choose stable OR development version, you can also install both one by one.

This step took the longest amount of time for me. Go get a nap!

It will ask you to reboot once.

Screenshot_2014-11-24-07-49-06

Once this is done, there is no intimation that it is completed.

When you reboot, it will give you an option to boot internal (Android) or Ubuntu Touch. Here you can select Ubuntu Touch and boot into it and setup.

Final Housekeeping. Boot into bootloader and lock the boot loader again:

fastboot oem lock

click on start to reboot your system.

Note: If you upgrade your Android, you will lose the dual-boot and have to start again from step 2 which may differ with your android version.

.NET goes open source

With other languages such as Java and Python getting large user base, this is a good move to gain some users.

Microsoft is open sourcing .NET, this should reduce the compatibility challenges with cross-platform applications developed using Microsoft Tools.

The main thing the Tox team is trying to do, besides provide encryption, is create a tool that requires no central servers whatsoever—not even ones that you would host yourself. It relies on the same technology that BitTorrent uses to provide direct connections between users, so there’s no central hub to snoop on or take down.

There are other developers trying to build a secure, peer-to-peer messaging systems, including Briar and Invisible.im, a project co-created by HD Moore, the creator of the popular security testing framework Metasploit. And there are other secure-centric voice calling apps, including those from Whisper Systems and Silent Circle, which encrypt calls made through the traditional telco infrastructure. But Tox is trying to roll both peer-to-peer and voice calling into one.

Actually, it’s going a bit further than that. Tox is actually just a protocol for encrypted peer-to-peer data transmission. “Tox is just a tunnel to another node that’s encrypted and secure,” says David Lohle, a spokesperson for the project. “What you want to send over that pipe is up to your imagination.” For example, one developer is building an e-mail replacement with the protocol, and Lohle says someone else is building an open source alternative to BitTorrent Sync.

An independent survey of 200 UK-based CIOs has revealed that they are only using about half of the cloud capacity they’ve bought and paid for, and that 90 percent of them see over-provisioning as a necessary evil.

Cloud provider ElasticHosts, which commissioned the survey, says: “Essentially, bad habits like over-provisioning and sacrificing peak performance are being carried from the on-premise world into the cloud, partly because people are willing to accept these limitations.”

Lets find out how the iPhone 6 compares with the Leading Android phones. I am only comparing the specifications and features and not the actually quality which is very subjective.

Here is Apple iPhone vs Samsung Galaxy S5, HTC One M8 and Xiaomi MI3. Galaxy S5 and One M8 are the premium Android phones while the MI3 is the poor man’s option or the rich mans budget phone which ever way you look at it.

As you can see the Android variants are leading in almost all the specifications which does matter. This includes the inexpensive Xiaomi Rather than innovating, Apple seems to only playing catch-up. Apply skillfully hides the finer specifications. Its your choice to stand in the queue for iPhone 6 or go with an Android at a cheaper price.

At CloudOpen, a Linux Foundation tradeshow held in conjunction with LinuxCon, the Foundation announced that an online survey of open-source cloud professionals found OpenStack to be the most popular overall project.

That wasn’t surprising. Although OpenStack is only four years old, the Infrastructure-as-a-Service (IaaS) cloud project is very popular with support from such industry giants HP, Red Hat, and VMware. What was somewhat surprising was that number two was Docker, the just-over-a-year old container technology.

2 Billions containers at Google each week!

That tech is called Linux Containerization, and is the latest in a long line of innovations meant to make it easier to package up applications and sling them around data centers. It’s not a new approach – see Solaris Zones, BSD Jails, Parallels, and so on – but Google has managed to popularize it enough that a small cottage industry is forming around it.

Zen story on religion

This also explains why meditation (truth) got converted to religion. Why conflict arises from religion, was religion created for vested interests ?

One day, Mara, the Evil One, was going through a village with his attendant when he saw a man doing walking meditation whose face was lit up in wonder. The man had just discovered something lying in front of him. Mara’s attendant asked what that was and Mara replied, “A piece of truth.” His attendant thought a while and asked, “Does it not bother you when someone finds a piece of truth, O Evil One?” Unfazed, Mara replied, “No, because right after that, they usually make a religion out of it.”

Ubuntu 32-Bit or 64-Bit ?

I often get asked this question 32 or 64-Bit? In the past I have told people to stick to 32-Bit because of compatibility issues but things have changed now. Quoting for Phoronix which recently did a benchmark test between 32-Bit and 64-Bit.

Going back years we have run 32-bit vs. 64-bit Linux benchmarks. While the results seldom change, we keep running them as the question of choosing between a 32-bit and 64-bit Linux distribution image is still a popular question… These tests drive in a surprising amount of traffic and I continue to be flabbergasted by the number of people still asking this question when nearly all modern x86 Intel/AMD hardware fully supports x86_64 and it generally means much better performance. Usually the only caveat in not using a 64-bit Linux image is if running a system with less than 2GB of RAM.

In the past there were issues surrounding the Java and Flash support for 64-bit Linux along with an assortment of other possible problems (e.g. with Wine), but all those major issues are a matter of the past. 64-bit Linux is in great shape and as long as you have a decent amount of RAM you really should be running 64-bit Linux.

If you are still in doubt, read the full article for the benchmark results.

If your usage is not much, use LibreOffice and save on your licensing costs.

If new data are true, Microsofthas a big problem.

The three-month study involved 148,500 employees at 51 global firms. SoftWatch found that  most employees were using the applications, largely for viewing documents or very light editing.

11 years of blogging!

Thanks you, to all my blog readers.

Today 3rd May 2014, I am celebrating 11 years of blogging! Wow, I too can’t believe it! I still remember, Rajesh Jain with whom I used to work then, encouraged me start a blog. And that’s when it all started. Before that I used to write articles, and found a direct benefit of writing was reading.  I ended up reading a lot. When you need to write, you need to read!

“The man who doesn’t read good books has no advantage over the man who can’t read them”. - Mark Twain

It has been a good blogging 11 years, been regularly irregular :) but still motivated to keep it going.

I first started with LiveJournal which was a good way to start, but soon moved to my own site on 22nd April 2004. I am happy to see that live journal is still live! Thank you LiveJournal for providing me a home :)

I was initially suggested Movable Type (MT), as that was the blogging standard then. But it wasn’t open source at that time but eventually did. But I decided to go with WordPress, which at that time was very limited as compared to Movable Type. But on hindsight was a good decision.

My first post, for those who are interested. While there are other older dated links, those were back dated entry added later to cover media coverages.

If you still aren’t blogging, I would suggest you do!

A few suggestions to first time bloggers:

  1. Decide where you want to host, there are many blogging sites. I would recommend WordPress.
  2. Decided if you want to have your own blog like www.yourdogsname.com or do you like yourdogsname.wordpress.com
  3. WordPress.com offers both the options to host your blog.
  4. I have chosen Dream Host as my blogging site because I can also host other content and sites on the same account, which is what I prefer. But if you only need a blog, then WordPress.com is a good choice.
  5. Be regular in your blogging, that’s how you would build your fan following.
  6. Focus on one topic, if its more than one, then they should be related. If you blog about cats and elephants, very few people would be interested in both. if you have more than one idea, would suggest have two different blogs.
  7. Social media is your friend, use your social network to publicise your blog posts. there are enough plugins for WordPress which can automatically post to your social network.

Thank you once again to all my readers, special thanks to those who take the time to comment. Happy blogging and happy reading!

The Short answer is No. Ubuntu was patched on 7th April 2014 and the bug was widely reported on 8th April, 2014. If you are using other operating systems,  you need to worry. Especially if its non-Linux based.

Read More: http://news.softpedia.com/news/Dear-Ubuntu-Users-Stop-Saying-the-Ubuntu-Is-Unprotected-Against-the-Heartbleed-Exploit-437846.shtml

The Heartbleed vulnerability that was discovered just last week took the world by surprise, but most of the affected services and operating systems have been patched. Unfortunately, some of the Ubuntu users haven’t understood how the patching process works and have started to flood the forums and other social media with the message that Ubuntu is vulnerable.

Before the OpenSSL issues has become known to the general public, most of the Linux distributions affected by the issue were patched. Most of the media reported on the problem on April 8, but the patch for the Heartbleed vulnerability was already in place on April 7. This is how the security notification looks like in Ubuntu.

Tesla running Ubuntu ?

There aren’t that many Tesla Model S owners around, but those who are do seem to comprise of people who have a different way of seeing things. Apparently, some Tesla Model S owners have already tried to hack their ride by wiring into the Model S’ communications system. A forum user who goes by the moniker of “nlc” managed to locate a number of ports and tap into the data which flows straight to the center console and navigation screens. It seems that these “hackers” found out that the sub-system actually ran on a version of the Ubuntu operating system, which so happens to be a variant of Linux.
Heck, there was even someone who managed to circumvent this discovery in order to have Firefox up and running on the center console touchscreen, although it does not seem as though there are other more invasive efforts to be made via the Ethernet entry point.
