PhotoRec & TestDisk file undelete

PhotoRec & TestDisk file recovery and FAT, FAT16, FAT32, NTFS undelete programs allow you recover accidentally deleted photos, videos or other files on SD cards and most other digital camera media and memory.

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted.

TestDisk is a powerful free data recovery program! It was primarily designed to recover lost partitions, repair FAT/NTFS boot sector, NTFS MFT and Ext2/Ext3 superblock and/or make non-booting disks bootable again when these symptoms are caused by faulty software or human error (such as accidentally deleting your Partition Table).

Google Ubuntu Chromium OS – the ‘real’ one

Apparently the real Google Ubuntu Chromium OS is based on Ubuntu and not on OpenSuse ! And the official download is only available as sourcecode which you have to build-it-yourself ! So by implication any other ISO or VM downloads that claim to be Chromium OS are possibly spoofs or fakes !

Thanks to Alan Pope for alerting me to the spoof ISO i downloaded last week !

.EU Internationalised Domain Names

the .eu domain is now supporting ACE Internationalised Domain Name (IDN) names which means that most european characters can now appear in the domain name part of URIs and URLs !

Examples:

Note : type the second (ACE encoded) version in brackets if your keyboard doesn't have a à character !

AMD 64-bit and Intel 64-bit confusion !

According to http://www.debian-administration.org/articles/534 Intel initially chose not to extend their IA-32 processor family to 64 bits, preferring to promote their own but incompatible HP PA-RISC based IA-64 "Itanium" processor family !

but then Intel adopted AMD's 64-bit extensions into their IA-32 processor family, calling them "Intel 64" (aka IA-32e and EMT64). Final generation Pentium 4 & D, Celeron D, and Xeon processors and all "Core 2" based processors now include AMD compatible 64-bit extensions.

To add to the confusion https://help.ubuntu.com/community/ProcessorArch lists a few dozen Intel processors but doesn't make it clear which type a Pentium DualCore is ! Which is what my Compaq A900 notebook says it has in it !

I have 4G of RAM that I have only been able to access 3G of so far (with 4 different OS's)

Update :
It seems that my Pentium DualCore has PAE (?) support and when I install from the Xubuntu x86 (32-bit ?) CD I CAN see all 4G ! So what benefits if any would I get from using the Xubuntu 64-bit (AMD64) CD instead ?

My SONY PIII says it is:
