Chromium Browser Causing Significant Increase in Laptop Power Usage

I recently noticed a strange bug while using Chromium web browser in Ubuntu 11.04 Natty Narwhal powered laptops and netbooks(Intel platform). There is an immediate spike in power usage whenever Chromium is running.

Chromium Browser Causing Increase in Laptop Power Usage

The way I found this out was even stranger. In our earlier Joli OS 1.2 review, I had mentioned about several performance related issues I faced with Ping-Eee OS, a netbook optimized version of Pinguy OS. One of the remedies recommended by the developers of Ping-Eee OS was to install and run Powertop, a tool to pin point applications that are consuming most power(only Intel platform is supported).

See above screenshot. Chromium browser is running and Powertop statistics show that power usage is around 7.9W. This was well above 8.0W on many instances.

Ending Chromium browser brings everything back to normal. Above screenshot is taken while Firefox 5.0 was running with same amount of tabs open. Power usage dropped to 5.6W and Wakeups-from-idle/second dropped to 380.0 from 1096.7.

A bug report has already been filed regarding same and it's title says it all. "Chromium Generates HUGE numbers of CPU wakeups and uses massive amounts of power". This bug affects Chromium 12.0. As you can see in that thread(towards the end), some users are reporting huge improvements with latest Chromium 14.0, but I haven't tried it yet. I will update this post once I finds any improvement in later releases of Chromium browser.

Top 6 Ubuntu 11.04 Themes

We have already featured a series of articles dealing with various aspects of the brand new Ubuntu 11.04 Natty Narwhal starting with the thorough review of Ubuntu 11.04. Now its time for some extensive customization of Ubuntu 11.04 Natty Narwhal's look and feel through a bunch of cool looking themes. Following is a collection of some of my favorite GTK themes for Ubuntu 11.04/GNOME 2.0 based desktops. Take a look.

Install Nautilus-Elementary Before Installing Themes
This is not a surprise anymore. Most of the themes for Ubuntu we are going to feature below will require you to install Nautilus-Elementary for optimum results. So, here is how you install Nautilus Elementary in Ubuntu 11.04 Natty Narwhal.

• Copy-paste the following commands into Terminal.

sudo add-apt-repository ppa:am-monkeyd/nautilus-elementary-ppa
sudo apt-get update
sudo apt-get dist-upgrade
nautilus -q

• Done. A more detailed take on Nautilus-Elementary can be found here and here.

• One other thing you might want to consider installing before getting started with GTK themes are these pretty icon themes for Ubuntu GNOME.

Nautilus Elementary Ambiance Theme

• Nautilus Elementary Ambiance theme is the perfect little modification of default Ubuntu 11.04's Ambiance GTK theme. Totally loved it. Here is what you need to do.

• Download Nautilus Elementary Ambiance theme first of all.

• Extract the downloaded ZIP file and copy "nautilus.rc" and the folder "nautilus" from the folder named "LAST VERSION".

• Open Terminal and copy-paste the following command.

gksudo nautilus /usr/share/themes/Ambiance/gtk-2.0/apps

• Insert your password when prompted.

• Paste the previously copied files ("nautilus.rc" and the folder "nautilus") into the Nautilus window you just opened(into the /usr/share/themes/Ambiance/gtk-2.0/apps directory ie).

• Reapply the theme(select a different theme and then select Ambiance once again).

Equinox Evolution Themes

• This is by far, my favorite collection of themes for Ubuntu 11.04 Natty Narwhal.

• Latest Equinox theme pack update brought in 3 more themes namely Evolution Dawn, Evolution Dusk and Evolution Midnight taking the total number of Equinox themes to 5.

• To install them in Ubuntu 11.04, do the following in Terminal.

sudo add-apt-repository ppa:tiheum/equinox
sudo apt-get update
sudo apt-get install gtk2-engines-equinox equinox-theme

• Also see: How to enable breadcrumbs hack for Equinox themes in Ubuntu 11.04?

Orta Theme

• Orta Theme by SkiesOfAzel is again one of my favorites.

• To install it, copy-paste the following commands into Terminal.

sudo add-apt-repository ppa:nikount/orta-desktop
sudo apt-get update
sudo apt-get install orta-theme

• Done. More details here.

Atolm Theme

• Atolm theme is also created by SkiesOfAzel, meant for dark theme fans.

• Though Atolm GTK theme looks pretty good with Awoken icon themes, I prefer Awoken Dark icon theme for it, think its slightly better. 

• Atolm theme is available in the same PPA as above, so if you have installed Orta theme from above, you need only the third command from below.

sudo add-apt-repository ppa:nikount/orta-desktop
sudo apt-get update
sudo apt-get install atolm-theme

• Done. More on Atolm theme here.

Divergence IV - "A New Hope" Theme

• Divergence IV - "A New Hope" Theme created by jurialmunkey. The next 3 themes we are featuring will also be of the same author.

• Download and Installation Instructions

Attack of the Clones Theme

• Attack of the Clones Theme - Download and Installation Instructions

There goes our list of favorite themes for Ubuntu 11.04 Natty Narwhal. A total of 10 themes have been listed above(including the 5 Equinox Evolution themes) and hope you found out your favorite. Two other things you need to know about Ubuntu 11.04's new Unity interface is the configuration options available through Quicklists and Application Indicators. Hope it helps. UPDATE: Nautilus Elementary Ambiance Theme + Orange Themed Clarity Icons looks pretty nice in Unity. What do you think?

Dangerous Wi Fi

Ilustrasi

JAKARTA - Hingga saat ini akses internet Wi-Fi digunakan oleh lebih dari 700 juta orang, dengan lebih dari 4 juta tempat hotspots di seluruh dunia. Sedangkan WiFi router setiap tahunnya diproduksi sebanyak 800 juta unit.

Berdasarkan temuan global research project yang dilansir oleh Online Security Brand Tracker, yang disampaikan oleh InSites Consulting (April-May 2011), dan analisa dari United Consultants, hampir separuh pengguna internet di dunia melakukan koneksi internet paling sering dengan menggunakan perangkat portabel, notebook menjadi perangkat yang paling populer (41%), kemudian diikuti netbooks (3%), smartphones (2%) dan komputer tablet (1%).

Sebuah catatan penting dari pesatnya peningkatan baik teknologi maupun penggunanya yaitu terdapat korelasi searah dengan tingkat keamanan.

Terkait dengan beberapa advice keamanan WiFi, ESET Smart Security 5 yang bakal menjadi versi terbaru Antivirus ESET menyediakan fitur-fitur yang akan bermanfaat untuk mengamankan koneksi dan data para user saat melakukan koneksi WiFi.

salah satunya adalah peringatan yang diberikan pada user untuk waspada kapanpun user terkoneksi dengan WiFi ditempat umum, untuk kemudian memberikan proteksi. Produk antivirus yang sekaligus menjadi produk generasi terbaru ESET mengkategorikan koneksi WiFi pada level keamanan maksimum.

“Apa yang tidak diketahui pengguna WiFi adalah resiko keamanan dari data terutama yang terkait dengan lalu lintas data yang terjadi saat memulai akses. Login credentials dan lalu lintas yang terjadi di dalam network akan ter-endus bahkan sebelum sebuah e-mail terkirim melalui koneksi Wi-Fi hotspot, begitulah umumnya modus pencurian data didalam jaringan, tanpa terdeteksi,” jelas Camp, seperti dilansir melalui keterangan resminya, Sabtu (6/8/2011).

Satu hal yang sangat diwaspadai adalah ketika ada jaringan hotspot dengan nama yang tidak dikenal atau nama yang mirip dengan jaringan resmi.

“Masalah bisa terjadi dari teknologi proxy, yang mampu mengintercept komunikasi WiFi, menangkap, mengcopy dan menyimpan copy data di komputer pelaku yang berada di local jaringan untuk kemudian mengirimkannya melalui jaringan Wi-Fi yang sebenarnya. Gejala terjadinya scam bisa dirasakan dari melambatnya lalu lintas email data anda . Tetapi karena jaringan ramai oleh lalu lintas semua pengguna dalam jaringan, maka akan suliit untuk mengetahui bahwa lalu lintas data kita diibajak oleh pelaku scam”, tandasnya.

Apple launches iCloud and iWork betas,

MobileMe's impending demise just got one step closer, folks. Apple's updated iCloud.com to now sport an official login page with what we're assuming is Cupertino's rendition of a CNC-machined aluminum unibody badge. It looks like those of you rocking iOS 5 or OS X 10.7.2 and who've also created an iCloud account are probably already busy frolicking through email, editing contacts and slinging calendar events all from the comfort of your browser. Those services already existed under its predecessor, but it looks as if Cupertino has spruced 'em up with fresh paint jobs. A screenshot from MacRumors also shows the addition of an iWork section, which we'd surmise means the previously siloed iWork beta now has a new place to call home. We couldn't get past the migration step with our trusty MobileMe account (disappointing proof is after the break), but you're more than welcome to tap the more coverage link and have a go yourself.

Oh, and if you're wondering how much it'll cost you to claim more than those 5GB that Apple's tossing in gratis, the folks over at Electronista have confirmed that an extra 10GB will cost $20 per year, while an extra 20GB runs $40 / year and an extra 50GB will demand $100 per annum.

World Wide Web (WWW) Rayakan Hari Jadi Ke-20 Tahun

LONDON - Ada yang istimewa bagi pengguna internet di seluruh dunia pada tanggal 6 Agustus 2011 lalu. Pasalnya tepat hari itu, World Wide Web (WWW) merayakan hari jadinya yang ke 20 tahun.

Ya, WWW yang selalu digunakan oleh para netter sebelum memasukkan alamat situs di internet. WWW 'lahir' pada tanggal 6 Agustus 1991, yang ditemukan oleh Sir Tim Berners-Lee. Pria asal Inggris tersebut meluncurkan laman web page untuk pertama kalinya 20 tahun silam.

Jauh sebelum diperkenalkan untuk konsumen umum, WWW ini dimulai sebagai halaman sederhana yang menampilkan link memungkinkan sebuah kelompok ilmuwan untuk berbagi data dalam batas-batas laboratorium mereka. Namun oleh Tim Berners-Lee memperkenalkannya untuk umum, dan sejak saat itu telah menjadi bagian tak terpisahkan dari kehidupan miliaran orang.

Dikutip melalui Daily Mail, Senin (8/8/2011), fisikawan kelahiran London yang juga ilmuwan komputer sedang bekerja di Organisasi Eropa untuk Riset Nuklir (CERN) di Jenewa ketika ia berusaha menemukan cara lebih baik untuk rekan-rekannya untuk menghubungkan data.

Dia pertama kali mengusulkan WWW pada tahun 1989 dan memposting data dari proyek di newsgroup alt.hypertext, proyeknya itu waktu itu dikenal dengan nama, "Proyek WWW bertujuan untuk memungkinkan semua link harus dibuat untuk setiap informasi di mana saja"

Sedangkan situs web pertama yang diperkenalkan adalah- http://info.cern.ch/hypertext/WWW/TheProject.html - yang berjalan di nxoc01.cern.ch.

Tidak hanya ingin sebatas digunakan untuk pengguna di kalangan ilmuwan saja, Tim Berner-Lee pun menyebarkannya ke seluruh dunia untuk kalangan umum.  "Kami sangat tertarik dalam menyebarkan web untuk daerah lain dan memiliki server gateway untuk data lain," katanya.

Dan berkolaborasi mereka lakukan pada tahun 1992, ada 50 web server di seluruh dunia. Dan dalam perjalannya selama 20 tahun terdapat 19.68 miliar lebih halaman yang diciptakan atau lebih dari tiga kali populasi dunia.

Ubuntu Software

Ubuntu Software Center is seeing its second round of upgrades, this time changes are even more dramatic. Good to see Canonical putting so much thrust on Software Center which has the potential to become Ubuntu's major money spinner in the near future.

Brand New Ubuntu Software Center Preview

Ubuntu Software Center upgrades are happening right now, but we are probably not going to to see the revamped Software Center in action until at least Ubuntu 12.04 LTS release happens. But if you are using Ubuntu 11.10 Oneric Ocelot Alpha release, you can preview some of the changes now itself(simply run the command software-center-gtk3 from Terminal). Here is a quick sneak peak of new Ubuntu Software Center.

Slider has become kind of a norm lately, from Android Market to almost all popular blogs out there now has one. Taking a cue from popular web applications like Android Market, Amazon App Store for Android, Apple's App Store and such, new Ubuntu Software Center has a wide featured-content slider on top. And it look strikingly similar to the one you see on top of omgubuntu.co.uk, among the biggest proponents of Ubuntu in the blogosphere. Bottom line is, the slider looks great. Still no real content is included in the slider and everything looks very unfinished at the moment. It will take time.

The other highlights of the new software center are the 'Top Rated' and 'New' application tabs right on front page. There is also a very neat categorization of applications on the left side that make the searching and finding of apps very easy and intuitive. The feature list otherwise remains pretty much the same at the moment, albeit better looking.

Good things apart, the new Software Center is far from a finished job. Rough edges are in plenty and the whole look and feel needs a lot of polish before the final release. But one should appreciate Canonical's resolve and commitment to keep on improving Ubuntu. The last major Software Center overhaul was not very long ago and now they are completely revamping it all over again. When Shuttleworth talked about his goal of acquiring 200 million Ubuntu users in 4 years, no doubt he was serious. Some really exciting times ahead. Stay tuned.
