Windows Vista

Finally got fed up with software compatibility issues and slow response with Vista premium that came pre-loaded on my Hp 6626us laptop compared to windows XP. Now the pain, uninstalling /downgrading to Windows XP. First – l tried copying the c:users folder to my western digital MyBook external usb drive as advised in PC Magazine issue for 5/2008. Kept getting Low memory error while doing this. Googled for help, and found out theres a Memory leak error known to Microsoft and l can only get the hotfix by registering for this on their website and waiting for a reply within about 8 business days. Finally decided to try xcopy from the command line. Vista kept suggesting l used the robocopy new command. I found this fails due to permissions for certain files. finally used xcopy with options for continue on error, copy all files and subdirectories. After about an hour, l had a 28Gb copy of my crucial filess. Next step, rebooting with my original XP CD. Problem – cant get into the recovery mode without the administrator password which the command lusrmgr.msc doesnt bring up. Now l find this out from the hp solutions section for their pavilion laptops:

“To logon as the Administrator, the Administrator account must be activated in Vista. By default, in Windows Vista, the Administator account is created but is not enabled.

  • In the Windows Vista Starter, Windows Vista Home Basic, and Windows Vista Home Premium editions, you cannot access or change the Administrator account.

  • In the Windows Vista Ultimate editions you can access and change the Administrator account.”

So, how can l run the following commands for preparing the laptop hard drive for XP: fixboot fixmbr cd ren windows winvista exit, from the Recovery console command prompt when l dont have access to the administrator account under Vista premium? Will let you all know how l resolve this.

Good link on installing XP on the HP pavilion 6626us

Link on resolving XP installation cannot find any hard drives due to lack of hardware support.

Update – Finally decided to upgrade my Windows Vista Premium to Vista Ultimate, which has most administrative functionality l’m used to from Windows XP. Plus l can run VPC2007 – Virtual PC 2007. Note – If you use 3DSMax 9 and have issues/errors running this under Windows Vista, simply go to the Autodesk website, support section and install SP1, then SP2. Now l;ve got to find the solution to the annoying clicking sound problem which seems to be related to a soundcard driver issue with Vista.

Changing the OEM Settings and logo in Vista:
Simply run regedit, and go to

ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionOEMInformation
You can create your own logo, as l did, simply create a 120×120 pixels BMP file and upload to c:windowssystem32oobe

If you try to install SQL Server 2005 SSRS – Reporting Services on Vista and it keeps failing saying IIS not found, follow this article – installing IIS7 on Vista. Apparently, when you install IIS 7 from the control panel, not all features are installed if a blue box shows, you need to see a check mark on the box next to IIS components for a full installation. Once this is done, the SQL Server 2005 install will allow you to install all components, especially sql server reporting services.

Robots, SDKs and Basketball

May the best team win the NBA 2008 Basketball Finals!!! May San Antonio Spurs win it!!

Amazing three-legged robots with great application in rescue operations, surgery etc – check out Technion “Spider Robots”

Apple had now released its Software development kit (SDK) for the popular iPhone – heres a link to the development center

As usual, Google has made new exciting changes with Youtube, they now offer API’s for more integration of your video creations into just about everything – including game creation. See their Broadcasting Ourselves web page. I’m currently reading Greg Iles “Third Degree”. Heres a lnk to an interesting Shaq, LeBron James and Dwight Howard NBA All Star dance video! And just when you thought your heart was immune from hacking, computer security experts release a report on the possibility of hacking via wireless and possibly electrically shocking someone to death – see Bruce Schneier’s Report on this security issue.

Smartphone – Windows Media 6

Just recently upgraded my Samsung Blackjack aka i607 operating system to Windows Mobile 6. The install, following the bit confusing instructions found here did work with some added intuition. Very pleased l didnt have to buy the Blackjack II aka i760 just to get WM6. Will post pictures soon. I’m impressed with the new OS, it does come with better default ringtones, windows vista like interface, office applications reader and l found a very useful tool Note2day which you can download from here, the Microsoft Windows mobile homepage. This free application allows you to quickly write notes, append to an existing note and review notes without much effort, something l always wanted in a Smartphone. You can also download the latest SDK for Visual Studio .Net smartphone software development from here. Note, forusers of Vista operating system, you need to install Windows Mobile Device Center 6.1 – and not just the latest version of Microsoft Active sync, in order to get your blackjack sync with your OS. Previously with Windows XP, 2000 etc , you only needed Microsoft Activesync to work with syncing between outlook and your smartphone.

Currently reading Greg Iles – 24 Hours. Good and engaging so far as expected. Reserved **all** his other titles at the Multnomah public library here in Portland, Oregon.

Deal or No Deal

I watch several TV shows, including 24, Prison Break etc. – but this show Deal or No Deal always hooks me. I even bought a mini arcade TV video game version of this popular TV show. Heres my take on the game – its NOT about winning a million, its about winning the most you can based on your odds!!! Its so crazy to see someone walk out with below $300 when they reached a crucial point where they could have walked away with at least $130,000 (half after taxes!). The crowd cheering “go one more time” or one’s supporters screaming that, or something in you, should not make you keep “hoping” your case has $1,000,000.00 ( $500k approximately after taxes).
For example, a contestant got to a 50-50 point with 2 low numbers and 2 large – 300,000 and 500,000, she was offered over $100,000. Her next large number on the board was $75,000. Think! If you knock out the 300k and 500k, you never will get offered anything close to 75k. She went ahead and subsequently knocked off in sequence 300k and 500k. Finally she settled for $23k which is about 1/2 after taxes. The smartest contestant to me while this new season (with $1million added each time up to $8million) kicked off was the lady who won about $306,000. Even though she and someone else where the only 2 contestants whose cases actually held $1million, she cashed in when the odds were best in her favour. You dont need a college statistics class to hopefully figure out this game show, but it sure helps to understand the basics of probability.

Linux From Scratch

Working on this now. If you want to learn/master how linux is built completely, you may want to try this challenging but interesting project. Heres the website link for linux from scratch

Another similar link using slax to rebuild/customize your own distro can be found at http://slax.org. SLAX is fast. compact and beautiful Linux operating system based on Slackware linux distro. If you wish to create a custom Ubuntu distro, try this link.

Below is my .bashrc and .bash_profile and the first command format that worked for me, despite a slightly different command format in the documentation online. Little tips and stuff l noticed will be posted here which might help you when trying out building Linux from scratch.

Source from which l get most of my open source software (good bandwidth esp. if you’re in the NorthWest) – Oregon State University FTP site

[root@localhost lfs]# cat .bashrc
set +h
umask 022
LFS=/mnt/lfs
PATH=/tools/bin:/bin:/usr/bin
export LFS LC_ALL PATH
[root@localhost lfs]#
[root@localhost lfs]# cat .bash_profile
exec env -i HOME=$HOME TERM=$TERM PS1=’u:w$ ‘ /bin/bash
[root@localhost lfs]#

lfs:/mnt/lfs/binutils-build$ time { CC=”gcc -B/usr/bin/” /mnt/lfs/sources/binutils-2.17/configure –prefix=/tools –disable-nls –disable-werror && make && make install; }
…………….creating cache ./config.cache

real 2m19.900s
user 1m36.257s
sys 0m30.604s

the times below was achieved on an Intel 6300 dual core machine with 1Gb RAM and a 300Gb SATA drive for Windows XP Pro, 42Gb second drive for Fedora 7

The second drive was split into 37Gb for / and 5Gb for /lfs and l always use 756Mb for a swap space as a matter of habit though l think 256Mb or 512Mb is okay.

When you get to this section: 5.5.1. Installation of Linux API Headers, you need to be in this folder not mentioned in the documentation:

lfs:/mnt/lfs/sources/linux-2.6.22.5$
