Installing Fedora 11 on top of Ubuntu 9.04 be careful

Installed Fedora 11 (64 bit) on top of Vista (64 bit - pain in a**) and Ubuntu 9.04 (32 bit). Grub of Fedora removed the entry of Ubuntu and Vista from grub. (No surprise name of Fedora's grub is Anaconda!!).

I thought it will be easy to fix (With Yogeshwar's help), I tried to copy the entries from
sda\boot\grub\menu.lst to
sda\boot\grub\menu.lst

on reboot I could boot Vista (I dont use it for months so not of much use)

For Ubuntu it was showing me entries in grub but selecting any of 4 Ubuntu options (including repair ones) were giving me "Error15 file not found".

Some googling told me that I could try with entry root(hd, )

I tried with different combinations of x and y (actually not x because I have single hard disk for my Dell studio 15). For wrong y values I got error 17 :D and for probably right y - I got blank screen and cursor :].

It would have been great if I would have waited for some time and tried to find solution for this problem - I did some thing stupid in application called "Palimpsest Disk Utility" on Fedora and when I saw that Ubuntu partition is not bootablle I tried to make it bootable by checking the bootable check button (aah stupid thing)

Now my Ubuntu partition is not even detected by Fedora and I do not see any option but to reformat my machine.

So moral of the story ... if you are installing Fedora after Ubuntu better take care... (I will try to write what care if I could successfully install both)

Some experiment (particularly with Linux)

I just tried few new things with Ubuntu Linux - I hope some people will benefit reading this

1. Go to Ubuntu in Applications->add remove programs find program called "Virtual Box". This software rocks!!.
I installed OpenSuse 11.1, 64 bit edition on Ubuntu with use of virtual box.
If you want to try new operating system without installing it on Hard disk then Virtual box is great option. Just isntall virtual box on your current operating system and install the Operating system you want to try using Virtual box.

To get more information about virtual box, OpenSuse and Ubuntu - Google these names.

2. I have found Google reader and one of amazing service offered by google. If you have not tried yet - I recomment it strongly.

3. I successfully compiled linux kernel for Ubuntu! I felt very great after doing this. Hope you will feel same - in Grub you will get to see your own entry!!

Hope I could try android in coming few weeks

Nokia E63 worth much more than its price

Few weeks back I lost my mobile (Sony K750), somebody stole it from hotel. Probably first time in life I was happy in for loosing expensive thing like mobile. But the reason for happiness was within few days/ weeks after purchase I faced lot of problems with K750i. I was required for waste hours for adjusting charger pin otherwise charging wont start - same was the problem with headsets. After a year or so new problems started, like if I put memory card into mobile - mobile will show white screen!! and there were many other problems in ~2.5 years of use.
One thing I will always miss about my K750i is its camera (camera is superb)

Now it was the situation that I was required to buy new mobile phone (which was not planned). I tried searching on internet for mobile handsets from Rs 5000 to 16000. I liked E71 but it was slightly out of my budget (18K+). From youtube I could find that E63 is much similar to E71. I read reviews and what I understood what the good points are
- 3G
- large display
- office applications like word/ excel/ power point
- pdf reader
- Query keyboard
- 8GB expandable memory
- GPRS
- Though not descent but 2.0 MPEG camera.
- Facility for video call

The negatives were
- 3G not 3.5G (does not matter to me because in India there are few service providers who give 3G and it is very costly - so why to be unhappy for 3.5G)
- 2.0 Camera (does not matter - this is more than sufficient for photographs expected from mobile camera)
- Camera is on opposite side of screen so in video call you can either see the caller or s/he can see you :( - (but this comes with advantage that while using mobile as camera you can see what picture you are taking :))
- GPS - I am not sure but probably the GPS is restricted only up to maps in E63 - probably you need external device for position information. But not a problem - as if you wont get GPS in this price range and you can connect GPS device with blue tooth if needed :)


Some of my personal experiences while using this E63
+ves
1. Being business phone in reviews there is hardly any mention of quality of music. My personal observation is quality of music is as superb as my Apple iPod if you use headphones. Speakers are not superb for listening to music. But speakers are superb if you want to use it as speaker phone.
2. Size - with the advantage of query keyboard and large display I think nokia has done good job as compared to E61. Though E63 is not very easy to keep in pocket it is neither very bulky.
3. I liked some of the feature of Nokia like - when write SMS - when you enter name of receipts there is auto complete option - superb!
4. This mobile do not have sliders and also do not have joy stick - superb!
5. Battery life is great - even after listening to music and almost 40mins call time / day - battery lasts for 4-5 days.
6. Torch - I find this as very useful feature of mobile. It was also present in K750i and it is really really very useful. You can use camera flash as torch.
7. Standard 2.5mm jack - again amazing - because it means that you can plug any speakers or headphones (actually not all headphones - depends on how much power they consume)

-ves
1. No provision of special keys to increase/ decrease voice.
2. No provision of special keys for camera.

Overall I will say for 12,400 Rs this is excellent mobile. If you want much more than media mobile at this price then surely go for E63.
