[Virtualbox Guest Additions] "Please install the build and header files headers? - Debian

Monday, November 30, 2009
Install the following on your Ubuntu Guest :

sudo aptitude install build-essential linux-headers-`uname -r`

The re-try the Additions, you should be fine :)

Install Guest Additions on Linux guest

Again, a fairly simple procedure. Repeat the first step. This will mount the VirtualBox Guest Additions ISO (included with the program) as a CD-ROM drive inside the virtual machine.
A file manager windows might popup, depending on your guest configuration, showing all the available options, including Guest Additions for both 32-bit and 64-bit systems, Windows and Linux alike - and even Solaris, not surprising, considering VirtualBox owned by Sun. On most modern Linux distros, the system will auto-mount CD-ROMs and launch file browsers / managers.
Addons in Linux
Choose the right package for your hardware architecture. In our case, this is x86. Open a terminal window and run the script with root privileges:
sudo sh ./
See image:
Run
Wait a few moments until the installation is complete. Reboot.
Installed
And that's it!

should a teenager go for a MacBook over a windows ?

Tuesday, November 24, 2009
hi, Linda,
it is my pleasure to provide you some information on that.

this Mas Book is a different kind of operating system from our normally daily used Windows system. users will have a whole different experience.

Why do so many people like to buy a MacBook? one of the many reasons, also most importantly, is that it is a sign of fashion. its appearance is certainly eye candies and not only teenagers like it, even me personally would love to have one as well. you can drop by at the Apple store at the Eaton Center (http://www.apple.com/ca/retail/eatoncentre/) to get a sense of their products.

speaking of the compatibility, it should not be a concern. there are tons of applications similar to Microsoft Office and other programs designed for Mac Book. they actually perform much better than the Microsoft ones. its Music and Graphic software are the top in the industry and all the professionals are using them.

one last thing i want to put stress on is that Jannie will not feel very comfortable while first using it since its design and concept are very different from Windows. but as an implicit trend, MacBook will be in the future as popular as Windows in normal families. so as to get start ahead, it is more beneficial for Jannie to get used to it.

my opinion is to go with a windows product at the moment. Windows 7 has just com out. it is with beautiful interface as well to satisfy Jannie's desire. it is easier to use and Michael and you are more familiar with it. when Jannie gets into university, it will be the perfect time to get her a MacBook (maybe some XXXBook much better than this MacBook). she will have the ability to get all the software she needs by herself or from her friends(free of charges). and at that time, it will take her 2 or 3 weeks to get used to it since she's already a fast learner by then.

hope the information could help.
Regards.
Peter.

Hi Peter,
 
I'd like to consult you a question on computer, since you're now studying to be an expert in this area.  Janine wants me to buy her an Apple laptop called "Mac Book".  What do you think of this brand? I'm not sure if it will have any compatibility issue with Microsoft Office software, or any other issues I should be aware of.  So I'd like to ask around before making a final decision.  Thanks in advance for your info!
 
Hope you're doing well with your study and internship.  Talk to you later.

Merge Multiple Emails to One Contact in Gmail

Monday, November 23, 2009
If today's Google Sync announcement has convinced you that it's time to move your contact management to Google servers, you probably need to do a little housekeeping with your Gmail contacts first.


For example, if you're staring in the face of numerous duplicate contacts that should represent the same person, the built-in contact merge feature in Google Contacts is a must. Just find the duplicate contacts, tick their checkboxes, and click "Merge these contacts...." Easy peasy. To manage your contacts, either head to the Contacts page in Gmail or to the unadvertised standalone site..

Thanks Michael!

Add Google Calendar to your Thunderbird

Google Calendar is a great, if not the best available tool to share calendars. However, it’s tedious to edit and keep track of it via the web interface. In saving time, integration is your best friend. Naturally, there is a vast amount of addons and tools to sync, integrate and simply work more efficiently with Google Calendar. For example you can sync it with mobile devices like the Blackberry or iPhone using GoogleSync. Then you can add Google Calendar to Gmail with several different Greasemonkey scripts. Now I will explain how to add it to Thunderbird.
For this you will need two Thunderbird addons:
1. Lightning adds a Sunbird type calendar to Thunderbird.
2. Provider for Google Calendar connects Lightning with Google Calendar.

After installing both of these plugins, you will notice several changes in Thunderbird. First of all there is a new sidebar holding the calendar. At the bottom of the old sidebar that is hosting the folders and address book, you should see three new buttons: Mail, Calendar and Tasks.

To integrate an existing Google Calendar, you first need to fetch your calendar’s address. Head over to the web interface, click the little arrow next to one of your calendars, and select >Calendar settings from the menu.
In the Details window you’re looking for the Calendar / Private Address section at the bottom. I found that both XML and ICAL URLs work, but XML is recommended. Whether you pick the calendar or the private address depends on whether your calendar is set to public or private.
Back in Thunderbird the first thing you have to do is click the Calendar symbol to switch from Mail to Calendar view.
Then click >File >New >Calendar… If the Calendar option is not available, you probably forgot to switch to the Calendar view.
From the Create New Calendar window select >On the Network, click >Next, select >Google Calendar as the format and insert the URL into the >Location field, click >Next, eventually enter your Google >User Name and >Password and click >OK, >Name your calendar, give it a >Color, click >Next and finally >Finish to complete the procedure.

And there you go, you have integrated your Google Calendar into Thunderbird. Editing the calendar works bidirectional, meaning you can add and edit events via the website or in Thunderbird and they will be synced automatically.
The Mozilla Wiki has a thorough page covering Provider of Google Calendar, including a section about bugs and limitations. There also is a Google Group discussing further questions.

how HD can this youtube get to????!!!

i think most of people have been living along google youtube for a while. having doubted that how hight definition Youtube can get to, i went to google's offical site on youtube where i can find many LONG and HD videos. the computer i am using is a out of date one. but has a video card on it.

then i started watching the video. here is the hyperlink in case you dont have it on hand , http://www.youtube.com/google#p/a/u/0/5JyFbF7QFlY.

here is the sample snapshot i got from the fullscreen mode.


 as we can see, even this 128Mb video card is not able to display this video clearly and smooth enough. and how fast is the loading speed? this video is more than one hour. and it only took me less than 3 minutes to finish loading all of it.

Rumors::?? the GPhone is Coming Next Year

Saturday, November 21, 2009
Well, place this one on the maybe, maybe not section, or rumors section, if you will. But according to “well-sourced rumors”, the good folks over at TechCrunch reported yesterday that the famous Google Phone was in fact coming in 2010. Today, they have an updated post on the same topic, but saying that the GPhone might end up being just a data-only device with VoIP.

We thought all this rumors were over last time when Google’s Andy Rubin, head of the company’s Android development, said that Google was not in the phone-making business. But yesterday’s post at TC ended with: “That’s all we have for now. We don’t yet know what the device will look like, how big it will be, or even if it has a physical keyboard. But we do know that Google is getting into the phone building business directly, and doesn’t seem too concerned about competing with all the other device manufacturers building Android phones.”
Today, the possibility of Google not “competing with customers” by launching their own device, seems a little more logical, since, “technically, it may not be a phone.” According to TC, “The GPhone may be a data only, VoIP driven device.” They’re also claiming talking with a person who hinted towards AT&T to be the provider of data services for the Google Phone.
The truth is, no body knows exactly what the future is bringing, or if Google will ever enter the phone market with actual hardware. But it is exciting to read about the rumors that show us the endless possibilities. Head on to the comments section and let us know what is your take on this matter.

How to switch to ROOT users in Ubuntu

if you have used debian before, you should know that there is a "su" command allowing you to get ROOT permission.
unfortunately, in ubuntu, it seems that they have banned the root login. so knowing you didn't set a password for root user, you still have no way to get in as a root user.

there are nifty ways to accomplish that.

1) there is a root terminal, go to the manu bar =>applications=>system tools=>root terminal.  use your password to get into it.

2) use the normal terminal, type in "sudo su" to switch to ROOT user.


ubuntu 9.10 problems so far

ubuntu has been out there for a while and i upgraded it one week ago. it seems not that stable so far. system has crashed couple times and it always freezes. i have to run the tty1 and  manually kill -9 the application seem to cause the problem. still unclear what the reasons are.


the freeze is seen as the screen or the application specifically dimmed in lightness


went to Ubuntu forum, got something like this below.


Ubuntu 9.10  freezes

This one has not been trouble free as I've gotten used to although I am aware of the vast complexities involved with an update to an entire operating system! Mine has been a clean install.

Although my system crashes (reboots) as well as freezes, and it does so far more often than once a day and not always when Firefox is running.

It's the worst issue I've ever had to deal with in Linux.

Debian live, one of many kinds

so what is a linux live CD???

A Debian Live system is a Debian operating system that does not require a classical installer to use it. It comes on various media, including CD-ROM, USB sticks, or via netboot. Why Debian Live?
Although the Debian Live project is about the framework to create your own customized Live system, we offer some prebuilt images. Currently, builds for three desktop environments (GNOME, KDE and Xfce) as well as the standard system are available.

How to Dual-boot windows 7 with Linux (with Linux installed first) -- the step-by-step guide


Scenario: You have Linux already installed but want to dual boot it with windows 7 on the same hard drive.
Summary of tutorial: We'll dual-boot Ubuntu 9.10 with windows 7. With Ubuntu already installed and owning the entire drive, we'll use the Ubuntu Live CD to shrink the Linux partition to create space for the windows install.
windows 7's MBR will overwrite GRUB during installation.

Instructions: 
1. Obtain a copy of Windows7.
2. Partition your disk with fdisk
3. Install Windows7.
4. Re-install Grub.
5. Edit Grub to List Windows 7.



Details:


4. Re-install GRUB

Now you have windows 7 but it has completely eaten your boot loader so you need to re-install grub.
Boot from the ubuntu live cd and go to terminal.
Type in terminal:

"sudo grub"
"grub> find /boot/grub/stage1"

That should return your Ubuntu partition in the form of (hdX,Y), use that:

grub> root (hdX,Y)
grub> setup (hd0)
grub> quit

(you don’t need to type the grub> bit)

That has re-installed grub but you can no longer see windows7

5. Edit grub.
Go to terminal from normal ubuntu and type :

“sudo gedit /boot/grub/menu.lst”

A large text file will open and at the bottom leave a line and add this:

title windows 7 beta (Loader)
root (hd0,1)
savedefault
makeactive
chainloader +1

(Do not type this line but if that does not work on re-boot try “hdo,0 or hd0,2” and so on until it works.)

Sony VAIO running Windows 7

Friday, November 20, 2009
it has been couples of weeks since window7 released. didn't want to install or "upgrade" it till yesterday. VISTA had always been taking a big chunk of my memories.finally i got pissed of then installed this windows 7. got the CD-key from University of waterloo e-academic for free. and it is a business version.


not as good as on youtube showed. so for i have found some bugs flowing around.

1) the VAIO integrated microphone doesn't work. but once i put my now earphone with the little mic, it sounds. thinking the microphone is not yet configured completely when installing all the driver. i have kept eyes on the VAIO official site waiting for the update.

2)display crashed. at some point yesterday, when i tried to use the windows updater while it's updating, the screen died 3 times. and showing chaos and blended colors on the screen. that scared the shit out of me and i thought the system was gonna crash. things are getting better now. haven't seen any display crash since then.
