Review #6: Ubuntu on Lenovo ThinkPad X1 Carbon

ThinkPad X1 Carbon

Ubuntu Linux is certified by Canonical Ltd. to run on Lenovo ThinkPad X1 Carbon. These instructions are for the old 3rd generation that I bought from Lenovo in 2015, but Ubuntu Linux 16.04 is also certified to run on the 5th generation, but I have not tested these instructions on the 5th generation of Lenovo ThinkPad X1 Carbon. You may risk to loose data and files on your computer by following these instructions, so take a full backup before you install Ubuntu on your ThinkPad X1 Carbon.

If you want to install Ubuntu Linux 17.04 (Zesty Zapus) Beta 2 on Lenovo ThinkPad X1 Carbon (3rd generation), the boot image for 14.10 is required for installation from scratch on this computer. For Lenovo ThinkPad X1 Carbon (5th generation), I think that the boot image for 16.04 is required. You can buy a bootable USB flash drive with 16.04 LTS from the Canonical Store, but I have not tested this on a 3rd generation Lenovo ThinkPad X1 Carbon.

To install Ubuntu on Lenovo ThinkPad X1 Carbon, you must first deactive the Secure Boot by entering the BIOS and turn the option Off.

Then you must download and write the boot image for Ubuntu Linux 14.10 to a USB flash drive with the dd command on an existing Ubuntu system. See the article “How to create a bootable Ubuntu USB flash drive from terminal?” for details on how to write the boot image for Ubuntu Linux 14.10 to the USB flash drive.

Then you can boot the system from the USB flash drive by entering the BIOS and select the USB flash drive as the boot medium and run the installer. After you have installed Ubuntu, you must boot the system for the first time and press the Ctrl + Alt + 't' keys to open the Terminal window, connect to and configure the local network by running sudo start network-manager and enter sudo do-release-upgrade -d to upgrade the distribution from 14.10 to 15.04 and from 15.04 to 15.10. You cannot upgrade to 16.10 from Ubuntu 15.10, so you have to manually upgrade apt from Ubuntu 16.04 with dpkg and manually upgrade to Ubuntu 16.10 from Ubuntu 16.04.

When you have 16.04, you must run update-manager -d in Terminal to upgrade to Ubuntu 16.10.

From 16.10 you can upgrade to 17.04 with update-manager -d in Terminal.

Review #5: The Imitation Game

I just watched The Imitation Game from 2014 by director Morten Tyldum and enjoyed it. The movie tells the story of Alan Turing, the British mathematician who broke the Enigma codes during World War II by building the Bombe machine that probably saved 14 million lives and shortened the war by 2 years.

The story of Alan Turing is probably one of the greatest triumphs and tragedies of human history.

The first time I went to Manchester with my British-Norwegian girlfriend was during UKUUG’s Linux 2001 conference and then we saw a simple Turing monument in one of the parks in Manchester.

12 years later, in 2013, the British society and the Queen officially apologized for the treatment of Alan Turing after the war.

The movie documents Turing’s codebreaking work at Bletchley Park, the code breaking operation site for the British military during the World War II.

I went back to England in 2013, 12 years after my first visit, and visited the MOSI to see the first stored-program computer and chatted with one of the volunteers at the MOSI who recommended a visit to Bletchley Park. I have been told that they destroyed most of the hardware after the war, but it is possible to enter the site if you make an appointment. It is probably a good idea to email the Bletchley Park staff before you go there.

Anyway, go and watch The Imitation Game to see a Hollywood portrait of Alan Turing and raw British code breaking intelligence at Bletchley Park.

Review #4: Motorola Nexus 6

2015-02-14 21.09.34
Nexus 6 is the latest Google flagship phone model from Motorola with the latest Android 5.0 release (“Lollipop”).

The 6.0 inch Quad HD display (1440×2560 pixels) is acceptable. The 4K (3840×2160) camcorder is very good. The 2 megapixel front-facing camera is OK.

The Android battery gauge indicates that the battery charges from 40% to 100% in 50 minutes with the included Motorola Turbo charger, much faster than my previous phone (Google Nexus 5 from LG).

Got the 64 GB version and have not ran out of storage yet.

Review #3: Android 5.0 on Google Nexus 5

I have been following and using Android phones since the first public release of Android 1.5 on the Android Dev Phone 1 manufactured by HTC.

Android 5.0, dubbed “Lollipop”, is the fifth release of Android and is now available for Google Nexus 5 devices. (Android 4.4.4 source code is available in the branch tagged ‘android-4.4.4_r1’ on, part of the Android Open Source Project (AOSP).)

There are also the Firefox OS and Jolla mobile platforms for phones, but I haven’t tried either yet. These are at least four different operating systems for phones now, competing with each other.

Apple’s iOS is a proprietary software platform built on a proprietary hardware platform, Apple’s proprietary hardware, while Android, Firefox OS and Sailfish OS are source code platforms.

Long live source.

Review #2: OS X on MacBook Air

The first computer I tried was an IBM PC. Then we got a second-hand Amiga 500. My main computer before I moved to Oslo in 1997 was the Amiga 1200 with the Miami TCP/IP stack. Then, a friend helped me build an IBM-compatible PC that ran the Linux-based operating system distribution known as Red Hat Linux for years. Then I switched to Debian. Debian GNU/Linux, a free operating system. Then I got Ubuntu, based on Debian GNU/Linux. These days I run Fedora on my main laptop and Ubuntu on my second laptop.

I never really tried the Macintosh before entering University of Oslo. It ran NCSA Mosaic and NCSA telnet, but I had to reboot that computer quite often.

I just tried MacBook Air with OS X from Apple Computer.

I am quite satisfied with it. Mac OS X boots very fast, it is somewhat stable (almost as stable as the Linux kernel, as far as I know), but the operating system sometimes runs out of memory. Adding more memory to the machine is possible with the correct screwdrivers, but warrants the guarantee, so unlike a computer from say Lenovo or Toshiba, you can’t just add more memory to the MacBook Air as easy. The MacBook Air is both proprietary hardware and proprietary software.

When the proprietary Mac OS X software runs out of memory, it opens a window that asks whether I want to close any running programs.

A reboot usually fixes the problem. I am used to reboot computers running real operating systems like Linux on hardware and kernel upgrades, however, the MacBook Air with Mac OS X still needs to be rebooted quite often compared to the non-Macintosh computers I have tried.

Review #1: Google Nexus 10

Nexus 10

Nexus 10 was launched by Google and manufactured by Samsung in late 2012.

The Nexus 10 is my first Android tablet and comes with a 10.6-inch screen and Wifi-only network connectivity.

I bought the Nexus 10 for 3090 NOK from and it arrived in the local post office after 3 days.

The CPU is a Dual Core AMR Cortex-A15 processor operating at 1,7 GHz. The graphics processor is a Quad Core Mali T604. The internal storage is 16 GB.

The 10.6-inch screen resolution is 2560-by-1600 (300ppi), so it can display video in 1080p.

There is no home button below the screen like there is on the iPad. The home button is on the top-right corner. The volume buttons are functioning opposite of the iPad. The lowest button increases the volume and the highest button decreases the volume.

The Nexus 10 tablet comes with Android 4.2, but is upgradeable to Android 4.3 and 4.4.2 in two cycles. From Google Play it is possible to install most Android apps such as Firefox, Gmail, Google Maps, Facebook, Dropbox, Netflix and NRK TV. I couldn’t install Spotify directly from Google Play, so I had to visit in order to install the APK file manually.

I was not able to find an official Samsung remote control app for my Samsung TV, but I installed Smart TV Remote which sort of works, although the user interface is cluttered.

There is a Micro USB charging socket and Micro-HDMI socket, and a 3.5 head phone jack.

Video recording is possible in 1080p with the rear camera and in 720p with the front camera.

I would give this tablet 3 of 5 stars.
