Ubuntu 12.04 LTS Precise Pangolin Latest New Features

The latest Ubuntu 12.04 LTS is going to be released in (28 April 2012), that is less than a week! The latest features of Precise Pangolin are:

1. Linux Kernel
Ubuntu 12.04 will use a kernel based on the 3.2.12 upstream Linux kernel, which include a patch that makes Linux powered laptop consumes more efficiently

2. HUD – Intelligent search feature in Ubuntu 12.04
Stands for Heads-up Display, HUD can be used to search for items in the menu bar in most applications. For example, if you are looking for a particular menu (or functionality) in GIMP, but can’t quite recall its position, you can use HUD to search it. Pictured here here is an attempt to search for ‘Blur’ filter for GIMP.

Ubuntu HUD

Currently HUD only works with application that supported Global menu, which means you can’t use it in LibreOffice.

3. Rhythmbox replaced Bansee as the default multimedia player
A decision came during the last Ubuntu Developer Summit (UDS). This move is connected to the new community decision to remove Mono and any application that depends on it from the default installation.

Another casualty is Tomboy note-taking application and gbrainy (game) which also depends on Monoi

**personally, I find depending on Mono application could be problematic, moreover those applications aren’t taking advantage of the ‘portability’ of the .NET platforms (It can’t be used on Microsoft Windows either, not without extensive hacking). So what’s the use of including Mono application on Ubuntu, except for bloating distros?

4. Global Privacy Settings
Ubuntu 12.04 LTS features “Privacy” option in the System Settings screen. The new Privacy Menu gives users the option of turning off History recording for users activities with a click of a menu.

Privacy 1

Privacy 2

Users may also disable activity recording for a specific group of applications (Instant Messaging, Web browsing, Office Documents, Emails and Multimedia), note that this option *MAY* only work on application that comes with Ubuntu default-installation.

5. Ubuntu *.ISO installer will exceed CD-ROM size
CD-ROM was used as installers on computer platform since 1994, back then the 650MB storage was larger than the average hdd capacity of around 320MB-500MB. The practice of releasing CD-sized ISO have since followed Linux distro for years, well after DVD drive and DVD-writers have become common.

Starting with Ubuntu Precise Pangolin (12.04 LTS), Ubuntu *.iso sizes will not fit CD-ROM anymore. it’s ISO size is estimated to be around 750MB to 800MB. Users may burn the ISO on DVD or use utilities such as UNetBootin to create bootable USB Drive.

My Thoughts
I think Ubuntu is going strong on this release with vast improvements on the usability, especially on the aspect of the UI user-friendliness to those who are new to GNU/Linux. However, I still thinks that Unity UI (and to the extend, the Ubuntu Software Center) is VERY SLOW even when running on a modern system as it took about 10 seconds to load Ubuntu Software Center.

Frankly, I think Ubuntu and the general GNU/Linux desktop community should improve the perceived latency of its UI first in order to persuade people to use open source operating system.

Linux Mint ‘Lisa’ – a release with the old GNOME look and feel

Linux Mint ‘Lisa’, a popular Ubuntu-based distro has been released! The most noticeable feature of Linux Mint is the inclusion of GNOME 3 desktop environment that emulates the look and feel of GNOME 2 desktop. Additionally ‘Lisa’ includes MATE, a GNOME 2 fork with various enhancements, including the ability to runge GNOME 2 and GNOME 3 on the same system.

The standard GNOME 3 installations comes with Mint GNOME Shell Extensions (MGSE), a desktop layer on top of GNOME 3 that makes possible to use the desktop environment in a traditional way.

AMD decTOP running Debian Squeeze

After upgrading my AMD decTOP with 160GB hdd, I’ve decided to install a fresh new operating system on it for some side-project that I’m working on. I choose to install Debian GNU/Linux 6.0.3 (Squeeze) on the machine.

The machine is currently running lighttpd web server with PHP5, samba server and sshd (using public-key authentication).

The specs of the machine are outlined in the screenshot.

Ubuntu: How to create a lot of entropy for GPG key generation from command line

Desktop Ubuntu users may have several ways to generate entropy relatively secure GPG keys (=>2048 bits), usually by moving the mouse and by typing random words. However this creates certain problem, for command-line user (especially those who are connecting through remote VPS connection).

Here’s a tip on how to produce enough entropy for GPG key generation:

  • apt-get install rng-tools
  • rngd -r /dev/urandom
  • then, proceed to generate GPG keys as usual: gpg –gen-key

Hopefully this tips will help you get by generating GPS keys over those VPS connections!

Mypapit GNU/Linux blog is now served with CloudFlare!

After long and careful consideration, I decided to enable CloudFlare for my blog.

CloudFlare is a content delivery network which aims to enhance website security and performance. CloudFlare CDN offers protection againts many forms of malicious activity including: spammers, email harvesters, SQL Injection, XSS, denial-of-service attack and suspicious web requests. Therefore saving valueable bandwidth from the web hosting machine.

My Personal Experience with CloudFlare
After a while using CloudFlare, I’ve notice that:

  • My site uses less bandwidth
  • The php-fcgi uses less (valueable RAM)
  • Less comment spam received from blogs
  • Site loads faster, not prone to being bogged down during peak hour

So far, so good, I love using CloudFlare…
