I would like to take “calcifer” as the user ID, so how to generate the md5 code for such a string??

Let’s see the manual:

MD5SUM(1) User Commands MD5SUM(1)
NAME
md5sum – compute and check MD5 message digest
SYNOPSIS
md5sum [OPTION]… [FILE]…
DESCRIPTION
Print or check MD5 (128-bit) checksums. With no FILE, or when FILE is
-, read standard input.
-b, –binary
read in binary mode
-c, –check
read MD5 sums from the FILEs and check them
-t, –text
read in text mode (default)
MD5SUM(1) User Commands MD5SUM(1)
NAME md5sum – compute and check MD5 message digest
SYNOPSIS md5sum [OPTION]… [FILE]…
DESCRIPTION Print or check MD5 (128-bit) checksums. With no FILE, or when FILE is -, read standard input.
-b, –binary read in binary mode
-c, –check read MD5 sums from the FILEs and check them
-t, –text read in text mode (default)

Obviously, we can’t make it as the usual way we used to do  ….
So we have to do a litter small trick: using pipe ~

echo -n "calcifer" | md5sum - 

PS:  ”-n” is to make sure we didn’t include the “new line” this invisible symbol .
So here can to the result:

calcifer@calcifer-laptop:~/Desktop$ echo -n "calcifer" | md5sum -

3ba9c9546d5dcb7ce2ee47967a83e324  - 

That’s what we need~~
And further more, it’s nautilus for some people to input the command like this:

 echo -n calcifer | md5sum 

In fact, the outcome is the same:

calcifer@calcifer-laptop:~/Desktop$ echo -n calcifer | md5sum -
3ba9c9546d5dcb7ce2ee47967a83e324  - 

So to fix this problem, we need to update the certificate file.

Use vi or gedit or any editor you like to open the file:  ~/.purple/certificates/x509/tls_peers/omega.contacts.msn.com
(For Pidgin in Windows, the path and file should be C:\Program Files\Pidgin\ca-certs\Microsoft_Secure_Server_Authority.pem)

Then copy all the text blew to replace the old content:

Save the file and have a try~

It’s so awesome. Ubuntu is my using Linux dist.. And I love its logo because it show love and peace to us, Reminding us that we are connected , no matter where we are and whom we are.

The other Tee I bought is a GNOME Tee:

I love this “big paw” very much. GNOME is my favorite Linux Desktop environment. It’s so elegant and effective. There is no more luxuriant decorative odds in Gnome. That make it very friendly to me.

Beside those two Tees above, I also got a mouse pad in Ubuntu theme with half price~~

Do you Love it too ?

Maybe Granola is a good choice for me. It’s a smart automatically energy management software. That sounds cool~ Now I only have to install it and let it do the job for me. And beside, I can also install a GUI interface to see what it has done.

Make a notice for myself:

1 download and run the install script: here

2 install software and GUI interface:

sudo apt-get install granola granola-gui

and it’s done~

http://www.ubuntu.com/

Just make a record for myself :

1st: Remove the gnash (If you have)

sudo apt-get remove gnash

2nd : Install nspluginwrapper and Flash 9:

sudo apt-get install nspluginwrapper flashplugin-nonfree lib32nss-mdns

3rd:  Flash 9 is not packaged, but the package installer script will fetch it from Adobe’s download site and install it. Now simply install nspluginwrapper as a Firefox plugin:

sudo ln -sf /usr/lib/nspluginwrapper/plugins/npwrapper.libflashplayer.so /usr/lib/firefox-addons/plugins/ sudo ln -sf /usr/lib/nspluginwrapper/plugins/npwrapper.libflashplayer.so /usr/lib/firefox-3.0/plugins/

OK, Bye

As new Linux release nears, founder Mark Shuttleworth explains his company’s plan for profitability.

With more than 8 million users, Ubuntu Linux is among the most popular Linux distributions.

But what is its mission? What are Ubuntu and Canonical, its lead commercial sponsor, really all about?

Ubuntu has desktop and server releases, and is gearing up both user and cloud services, all of which are set to be updated in the new Karmic Koala release due out later this week. With all the different products and directions, Ubuntu founder Mark Shuttleworth faces questions about the focus and definition of the distribution, as well as the profitability of its corporate backer.

In a press conference call today, Shuttleworth tried to explain.

“The mission of Canonical is to deliver all the benefit of free software to a variety of audiences,” Shuttleworth said. “We started with desktop, because we thought that was place we could make the most distinctive splash. The desktop was largely neglected and at the same time there were changes afoot in the core infrastructure of Linux at the kernel level that meant we were confident we could surprise people at how easy [it was] to install and use the desktop if someone was focused on it.”

Ubuntu competes against multiple Linux distributions, including those from Red Hat and Novell, as well as community-based distributions. Both Red Hat and Novell offer enterprise Linux desktops, though specific efforts focused on the consumer segment are not currently the main thrust.

Shuttleworth said that Ubuntu to date has been successful in expanding the Linux desktop footprint, and is now interested in increasing the number of places where it can deliver the benefits of open source software.

“We’ve already done a lot of work in developer ecosystem and we’re now increasingly interested in the non-developer consumer ecosystem, so that’s what all the OEM work is about,” Shuttleworth said, declaring that his focus was on “making sure that Ubuntu gets pre-installed and Ubuntu is available from Dell.com and others and making sure that Ubuntu is the default alternative to Windows.”

He added that Canonical has a similar vision for Ubuntu on servers and in the cloud. He admitted that having different products for different market segments does represent some real challenges for Canonical as a small firm.

In terms of the company’s organizational structure, Shuttleworth said that there is a core Ubuntu platform team at Canonical, which is divided into desktop, server, mobile and netbook groups. On the sales and marketing front, separate groups are tasked with focusing on OEM, enterprise and consumer efforts.

“It is a stretch and it is a challenge,” Shuttleworth said. “But the real prize for us is to show that the free software ecosystem can be delivered as a platform which spans from the most lightweight devices right the way through to the most heavy-duty devices.”

He added that there are real benefits to having a complete platform, giving developers the opportunity to both develop and deploy applications using Ubuntu’s brand of Linux.

“The consistency of platform and ecosystem is highly valuable to us and to our users. That’s why we’ve given ourselves the harder job of delivering a complete platform rather than going for a specific niche market,” Shuttleworth said. “Time will tell whether it’s achievable. It’s wonderful to do the impossible so long as it’s not actually impossible. We’re certainly surfing close to the edge of that line.”

But the broad product mix poses a threat to Canonical’s profitability, at least in the short term. It’s a concern that Shuttleworth recognizes, but he sees the silver lining in the longer-term picture.

“I have no concerns about our ability to be profitable,” Shuttleworth said. “If necessary, we would have the option to focus on specific areas that are already self-sustainable. My preference is to push the organization faster, to continue to invest in and to continue to create the feeling of a complete platform.”

Canonical is a privately-held company, and Shuttleworth does not disclose its financial performance. Last year, he admitted that Canonical was not cash-flow positive.

“Profitability is a matter of choice as to how much we’re willing to invest, whether we see the appropriate returns on that investment and whether we see it as the right thing to be doing,” Shuttleworth said. “Right now I’m absolutely convinced that we want to be delivering Ubuntu as an end-to-end solution, and that requires us to invest in multiple theatres of battle at the same time.”

FPS Game is one of the most popular game type. You can’t find out how many people had played Counter Strike or Doom. But those games are too violent and bloody. It’s not suitable for the kids and girls to play such games. But the game that I want to introduce today will give FPS game another life to be suitable to all people.

Teeworlds is a free online multiplayer game, available for all major operating systems. Battle with up to 16 players in a variety of game modes, including Team Deathmatch and Capture The Flag. You can even design your own maps! I admit that the first reason why I love this game is its excellent portability. When I searched games on Ubuntu, my eyes were caught by a cute image. This small little ‘ball’ is called Tee. They have a round body and short hands and feet. But don’t think that these lovely and little ‘balls’ would be very friendly and harmless. In fact, they are super strong and armed. Yep! they are war animals.

Tees are skilled with many weapons. No matter the scatter gun, rocket launcher, beam rifle or just a wooden hammer, those small tee will fight incredibly and show you what is the real weapon master. Even the rope which used to clime at usual can be a tool to make enemies down without finding out what has happened.

To join their world of war is very simple. Just go to the official web site www.teeworlds.com to download the client that suitable to you OS. And install it within a minute then ~ Let’s war~

The first step is to custom your own tee, you can choose your favorite character image and named it with a cool ID. Then turn back to the host list and pick up the host the suitable to your location with a nice ping. And Loading…

The rest of this game can be learn by you natural war instincts. And I am waiting for your challenge or cooperation.

BTW: you can leave your Teeworld ID in this post’s comment, that would be easier to meet our comrades.

We know that WOW’s PC client software is only supported Windows. To the Linux users like me, one of the way to play this game is to install wine which can run Windows version software under a Linux environment. That’s easy to make it cause Ubuntu has built it easy to install. But I countered another problem, the Chinese character and input method support…

After search on Google, I found that the already built version wine-cn haven’t released and I have to “hack” it by myself.
The job I have to do:

• 1 download the source ball of wine
• 2 patch the source file with Chinese charset support
• 3 prepare the environment of building wine on 64-bit platform
• 4 compile and install wine
• 5 fix the Chinese character display by adding “gdi32.dll.so”
• 6 Download and Install WOW~

1  go to http://www.winehq.org/site/download to download the wine source ball

2 extract the file and patch with the “wine_charset.patch”

cd wine-1.0
patch -p1 < wine_charset.patch

3 Run this in Shell to prepare:(Ubuntu 9.04 only)

sudo apt-get build-dep wine

4 Configure, make, and install:

CC=”gcc-4.3 -m32″ LDFLAGS=”-L/lib32 -L/usr/lib32 -Wl,-rpath,/lib32 -Wl,-rpath,/usr/lib32″ ./configure -v

make

make instal

To compile 14.9MB source ball is a time wasting job.

5 Fetch the gdi32.dll.so and copy to the wine

sudo cp gdi32.dll.so /usr/lib/wine/

6 Install and Run WOW just like in Windows~
