If you are confused by the term “codec” and “container format”, then here are a simple explanation about them.

Multimedia files, e.g. music or video files, have both codec and container. If you purchase music from iTunes Stores, they will give you music files with extension “m4a”. Sometimes they also give bonus (music video) in extension “m4v”.

 

Codec is a program (or algorithm) that capable to read (encoding and/or decoding) data.

Container is a way of storing data. Container (aka wrapper format) describes how data and metadata are stored. A program might be able to read and identify container file and might not be able to read data in it. This is caused by the program which read the

 

You can imagine this container format and codec as a locked box. To open the box you need a key. So the locked box acts as container format, while the key acts as codec. You yourself acts as a program.

Pretend that someone gives you locked box (container format). You know that it is a locked box, right? But, you don’t know what inside this locked box. So, you need a key (codec) to open the box. If that someone gives you the key, you will be able to see what inside the box. If he or she doesn’t give you the key, you will not be able to see what inside the box.

 

So, here you are. Pretend that you play your purchased music from iTunes Store using Windows Media Player 11. The music is in m4a (this is container). Generally, you will not be able to play that music, because Windows Media Player 11 need a codec (a key) to encode what inside this m4a. That key is called Advanced Audio Coding (or H.264/MPEG-4 Part 10). Just search the internet about this codec, install it, and then voilaa. Windows Media Player 11 can play the m4a music.

A codec package that is always my favorite is K-Lite Mega Codec. It contains many codecs that you might need to play your multimedia files.

I accidentally found this Katharine McPhee’s song. It is called Terrified. She duet with Chuck (Zachary Levi)!!! What?! The song is mellow, tells about a lover, nice song I think.

On May 4, 2010, a new version of the song featuring actor Zachary Levi premiered on Entertainment Weekly‘s website and was made available for purchase on iTunes. On May 7, 2010, an accompanying music video for the new version premiered on the music video website Vevo. The album version of the song (featuring Jason Reeves) has sold 41,000 downloads in the United States (source: Wikipedia)

A few month ago I decided to install Windows 7 and Ubuntu 9.04. At that time on my computer I have Windows XP already. I was going to triple boot.

First I created a new partition for Windows 7, and then partitions for Ubuntu and it’s swap. It’s look like figure below if I open Disk Management on Windows XP (Start > Run > type “diskmgmt.msc”).

diskmgmt xp

diskmgmt 7

2 Primaries and 1 extended (extended contains 3 logical drives).

 

Then I install Windows 7, and Ubuntu after it.

Someday I logged in to Windows 7 and ran Disk Management. I expected to see something like figure above on Windows 7, but instead i saw this:

diskmgmt 7

 

What on earth was going on? I didn’t know too. As you may know that a disk:

  • can contain max 4 primary partitions, but it can’t have extended partition.
  • if I am not wrong we can only create 1 extended partition, but we can create unlimited partition (logical drive type) inside it.
  • or in general we can say:

amount of primary partition + extended partition  <= 4

So, what about figure before (the one that I ran on Windows 7)? I don’t know the answer for that question right until now. The effect of this issue was I can’t resume my computer from hibernation (from XP or 7). It was always error that saying “Can’t resume your computer, error on hiberfil.sys” or something like that.

To solved the issue, it made me to recreate all of my partitions (but Ubuntu partition was not included, because I suspected that this issue was caused by Ubuntu partition and it swap). At the end, dual boot XP and 7 run smoothly.

Maybe sometimes we just want to post a new article on our blog. It is a headache for me to repeat every steps that I need to take to post my article. Open web browser, type the URL, login (enter username and password), go to post new article, blah blah blah and blah blah blah.

By using Windows Live Writer, we can eliminate that boring steps. Just open Windows Live Writer, type your new post, and publish. That’s it! Windows Live Writer can work on Windows Live Spaces, SharePoint blog, Blogger, WordPress, TypePad, and others.

Windows Live Writer

If you familiar with Adobe Dreamweaver or Visual Studio, you must be notice that this Windows Live Writer also have three view mode: Edit, Preview, and Source.

Edit is view mode where you can type like typing in Microsoft Word. In this mode, Windows Live Writer will load default theme of your blog automatically. Look at screenshot of Edit View below.

Edit View

Preview mode is a place where you can view your blog as you view it in web browser.

Preview Mode

The last view mode is a little bit geeky :D, Source View. Here you can manipulate HTML code.

Source View

The most important feature that I think most useful is we can insert or remove image easily. We can add image effect too (it feels like using Microsoft Word or other word processing software).

You can download this Windows Live Writer at Windows Live Essentials. Yap, Windows Live Writer is a part of Windows Live Essentials. If you just want to install Windows Live Writer only, you can always customize the installation. When you try to download this Windows Live Essentials, you will be given a small program setup (1.18 MB, because it’s an online install/required internet connection when installation is in progress). But, if you want a full offline install, just cancelled the setup download before, look at that website again, and on the left of the page there’s something like figure below. You will get a full setup, it is 134 MB.

This is my first time using this Windows Live Writer. I can’t write much, perhaps next post.
