Seperti biasa, kita boleh menukar tema ubuntu kepada apa sahaja dan antara yang terbaru dan ingin saya kongsikan di sini ialah tema Mac OSX Lion untuk Ubuntu 12.04.
Buku pertama, Mudahnya Twitter kini di pasaran
Perancangan awalnya saya dengan pihak penerbit iaitu PTS Netmedia Sdn Bhd ialah untuk menerbitkan buku berkaitan sistem operasi Ubuntu. Saya telah siapkan proposalnya dan ia telah diluluskan. Namun oleh kerana sebab-sebab yang tidak mengizinkan, saya memilih untuk menulis buku yang simple, ringan dan santai terlebih dahulu.
Buku Mudahnya Twitter ini berharga RM10 sahaja dan sekiranya pembaca membeli Online di Kedai Buku PTS, ianya hanya RM8.50 (http://www.bookcafe.com.my/en/gadget-perisian-and-komputer/mudahnya-twitter-en.html)
Insyaallah, di masa akan datang sekiranya diizinkan tuhan, saya bercadang untuk menulis tentang banyak benda tentang dunia IT dan salah satunya ialah buku panduan Ubuntu. Semoga dipermudahkan.
Ubuntu 12.04 : Cacat Tanpa Hibernate?
Precise Pangolin tanpa Hibernasi
Christopher Tozzi
Kekurangan sokongan daripada sistem operasi untuk hibernasi, atau keupayaan meletakkan komputer untuk “tidur” tanpa menggunakan elektrik, ialah satu kecacatan utama disebalik rilis Ubuntu yang terbaik. Dan ia tidak membawa petanda baik, cita-cita Canonical untuk menawan komputer desktop.
Hibernasi adalah penting bagi menjimatkan tenaga elektrik. Tetapi apa beza Hibernate dengan Standby? Artikel daripada Lifehacker ada menjelaskan tentang Hibernate Vs Standby. Bagi yang ingin mengembalikan fungsi hibernasi secara manual, boleh rujuk di sini.
Jadi pendapat anda perlu atau tidak fungsi hibernasi ini?

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 65536 bytes) in ….
The error above was found on a LAMP (Centos 6, Apache, MySQL and PHP 5) environment.
Where is the problem?
Facts:
134,217,728 bytes is equivalent to 128MB. These numbers indicate that a limit of some memory has been reached.
2 power of 16 = 65536
2 power of 27 = 134217728
There some sites that suggest to increase the memory limit of PHP with memory_limit directive in php.ini file. But this will only prolong the problem to another day. How are you going to keep increasing the memory limit?
Possible approach:
Troubleshooting (approach 1):

There some sites that suggest to increase the memory limit of PHP with memory_limit directive in php.ini file. But this will only prolong the problem to another day. How are you going to keep increasing the memory limit?
Possible approach:
- Some where along the setup, the application is eating up memory through an infinite loop. Review location of the application file (model) that is causing the error.
- It states "Fatal error" and not "Php Fatal error", indicating Apache web server is sending the error instead of PHP. Check if web server was restarted after the memory_limit was increased in the /etc/php.ini file.
- Database configuration needs to be edited for large selects or join processing. (High performance Innodb)
Troubleshooting (approach 1):
- Use phpinfo() to compare the memory_limit with what was set in php.ini file. Check Loaded Configuration File, did it say which php.ini file was loaded? This file can be placed in many places.
- In PHP, apply the memory_get_usage() to display memory in used.
- For database related calls, use the function mysql_free_result() to release memory used by variables.
- If the memory grows large, it may be possible to remove the object from the memory via the unset() function.
Troubleshooting (approach 3):
- Create a large database and execute various calls via the web browser. Sample large database can be found at Wikipedia.

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.
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.
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.
