Menghemat Bandwidth Hosting

Pengalaman akhir Juli 2009 lalu dimana bandwidth hosting blog ini mencapai limitnya dan akhirnya tidak bisa diakses membuatku mencari tahu bagaimana cara menghemat bandwidth.
Well, pertama-tama cari tahu dulu faktor yang mempengaruhi banyak sedikitnya pemakaian bandwidth. Jadi hal yang mempengaruhi hal itu antara lain adalah besar ukuran halaman web. Wajar lah, makin besar ukuran, maka akan semakin besar bandwidth yang dipergunakan. Kemudian yang kedua adalah banyaknya pengunjung. Ini juga masih berkaitan dengan faktor pertama tadi, dimana ini seolah-olah hanyalah faktor pengali dari ukuran halaman web tersebut. Jadi makin banyak pengunjung maka sudah pasti semakin banyak juga bandwidth yang terpakai. Faktor yang ke tiga ada banyaknya yang subscribe ke feed.

Dari tiga hal yang saling berkaitan di atas, maka hal yang dapat dilakukan adalah memperkecil ukuran web dan mengalihkan feed ke pihak ke tiga.
Untuk saat ini, saya hanya akan membahas faktor yang berkaitan dengan ukuran web saja.
Mengenai faktor yang berkaitan dengan ukuran web maka perlu diperhatikan bahwa ukuran ini bisa berasal dari text artikel, dari image di artikel, dan dari theme dan plugin. Asumsi yang digunakan di sini adalah engine web sudah optimize.

Ukuran besar yang disebabkan karena text dapat dihindari dengan melakukan hal berikut :

• 1. Batasi jumlah post di bagian frontpage.
  Menurut saya jumlah 5 posts saja di frontpage sudah cukup untuk blog yang di update secara fair. Maksud fair di sini adalah tidak terlalu jarang dan tidak terlalu sering di update.
• 2. Gunakan fasilitas readmore untuk artikel yang panjang.
  Readmore akan memotong artikel sehingga artikel yang ditampilkan di frontpage bisa diperkecil.

Untuk ukuran yang besar yang disebabkan karena image di artikel, maka bisa diatasi dengan mengupaload gambar tersebut di free image hosting yang punya bandwidth dan tempat penyimpanan yang besar. Perlu diketahui bahwa sifat gambar di artikel adalah tidak berubah-ubah lagi setelah dimasukkan di dalam artikel. Read More …

My new Gadget : HP Mini Note 2140

Finally I bought ultra-light notebook or commonly known as mini notebook HP Mini Note 2140 with 6 cell battery and 10.1 inch screen at Device Vaganza, an event which was hold by my Company four days ago. At that event, I was  given extra discount by the seller for buying that mini notebook so I just need to pay at price USD 450 with exchange rate at that time was 1 USD = 10,400 IDR while the normal price in the market is USD 585. That means I save USD 135 for this case.
The packets which were received along with mini notebook were soft case bag and another big bag from HP.

My mini notebook is powered by Intel® Atom™ Processor N270 (1.6 GHz, FSB 533, Cache 512 KB) with memory 1GB DDR2 SDRAM 667MHz. The maximum memory for this mini notebook is actually 2 GB but when I asked the seller if I want to add the additional memory, they said that I should go directly to their office as they do not bring the additional memory, so I decided to cancel for this one.
The storage for this notebook is 160 GB Hitachi Hard disk 5400 RPM SATA with Drive Guard Technology (HP’s 3D DriveGuard accelerometer) which able to loc the ring of the hard disk when there is any vibration.  The graphic card is powered by Intel® Graphics Media Accelerator 950 DVMT 64 MB which shared from memory. For Connectivity, this notebook have WIFI Broadcom 802.11 a/b/g which can support the data rate up to 300Mbps, Gigabit Ethernet Marvell Ethernet Integrated Controller (10/100/1000), and also have Bluetooth wireless technology .

This HP Mini Note has surface covered by professional-looking aluminum and magnesium-alloy that make this mini notebook different with the other mini notebook. The screen size is 10.1 inch with resolution 1024×576. At the up of the screen, we can find VGA webcam as built in. This notebook also have nearly full sized keyboard with nearly similar to standard Notebook (92% of standard keyboard). The touch pad buttons is on the left and right instead of underneath and the touch pad can be deactivated or activated by on/off button. At front side of this mini notebook, we can find power button, drive light, and wireless button. On the left side we can find USB port, vent, and audio in/out jack while in the right side we can find Express Card Slot, SD card reader, USB port, LAN Port (RJ45), power connector, battery light, and also loc slot.

HP Mini Note 2140 which I bought is using Windows XP Home as Operating System with 60 days trial of MS Office 2007 and trial of antivirus Mc Afee Total Protection for 30 days. With six cell battery, this mini notebook can be used without recharge for approximately 5 hours. At first time, the 160 GB SATA Hard disk is not being partitioned so there is whole 160 GB as Drive C. When I tried to make partition, I could not get the result as I expected.    I don’t  know why this 160 GB cannot be partitioned  using standard method of partitioning windows XP. Then, I tried to use Partition Magic but I still cannot make partition. After that, my Friend suggest me to use EPM (Easeus Partition Master), a free partition software which look similar with partition Magic. By this software, finally I successfully make partition on my 160GB Hard disk into two partition, 25 GB as Drive C and 124 GB other as Drive D.

My Blog goes Mobile Version

The effect of booming in smart cellular phone like Iphone & Blackberry and the decreasing of data charging by cellular operators, have caused the increase rapidly in mobile web activity. Therefore in order to accommodate mobile web activity, there are many blogger provide a mobile version of their blog. This mobile version is aimed to make browsing the Web from mobile devices comfort and fast by scaled down the theme and content of blog suitable with the screen of the device.

Actually, I realized that I should add mobile version of my blog when I browsed my blog via my cellular phone. At that time, I could not do fast browse due to long time response of loading. And then, after the page was loaded perfectly, the page which used blueweed theme was very not suitable with small screen device so I need to scroll left and right in order to read completely. 

I know that careful steps need to be taken when optimizing a website to be mobile friendly especially in accessibility. Then I start searching the wordpress plugin which able to create mobile version of my blog which have user friendly structure, simple graphic or have no graphic, and have simple theme which can be easily modified.

After further searching, finally I find wordpress plugin which support mobile version called wordpress mobile pack.

This plugin includes a mobile switcher which able to select themes based on the type of visitor who is visiting the site. If the visitor comes from Computer browser, the mobile switcher will switch the theme into original theme which is blueweed theme, while if the visitor comes from mobile cellular phone browser the mobile switcher will switch the theme into mobile version. This plugin also have the ability to select mobile themes  so I can easily modify the original mobile theme. The other important feature is called device adaptation. By this feature, this plugin has basic recognition of mobile devices and is capable of rescaling images, splitting articles and posts in multiple pages, simplifying style and remove media so the mobile version will be fit in cellular browser.
Below is my score for this blog in mobile version based on ready.mobi

So in my opinion, this plugin is worth to be tried

Push email for Nokia 6120 Classic

I searched the ability of my Nokia 6120 classic which using Symbian S60 3rd regarding push email ability and found the fact that actually my Nokia 6120 classic able to do push email but should be installed push email application.

Before writing Nokia 6120 classic push email applications, it will be better if we know what the term of “push email” is. Based on Wikipedia, Push e-mail is used to describe e-mail systems that provide an “always-on” capability, in which new e-mail is instantly and actively transferred (pushed) as it arrives by the mail delivery agent (MDA) (commonly called mail server) to the mail user agent (MUA), also called the e-mail client.

So if this kind of push email system client is installed in phone, the email will be like SMS in phone.

Well, after further searching, I found that there are two good push email applications called system seven and the beta version of Nokia push email. For System Seven, i am little worry about the ability of the application to auto send sms into an isle of man number without our permission if we want to install system seven application in the phone. I don’t want to take a risk for installing that application. Therefore, i skip this application and then try to install the beta version of Nokia push email which can be found in http://email.nokia.com.
