The Googles doesnt like ‘ASP Debugger’

February 26th, 2009 4 comments

I had a friend ask me about an ASP Debugger today, so after talking for a little while I promised to email him a few things when I got back into the office. Just when I had a tick, I thought I’d google the bastard to see what results I’d find – as I havent done ‘classic ASP’ development for quite sometime – I shudder to think writing like that again.

Anyway, fired up a new window in firefoxy, CTRL+L, {TAB}, type in ‘ASP Debugger’ without the quote. What do you get?

What, you reckon I'm a virus? How dare you, just WHO do you think you are.

What the, however this only occurs searching through the firefox where as the normal google search doesnt seem to worry.

Queue'ing it up

Queue'ing it up

You will automatically move on to the site when it’s your turn. Technology is so cool.

Ah wells, time to go have a shower, walk Neo and eat some dinner. Meanwhile you can read an interview with John Carmack and Marty Stratton about the magic that happens behind the scenes then spin up that old Quake III Arena CD from your archives and start playing!

Citrix gives away XenServer & Enterprise Tools for Free!

February 24th, 2009 1 comment

A quick note before I head to bed tonight, Citrix has decided to give away its OSS XenSource virtualisation platform for free…

If you’re reading this, you already know the news: XenServer, our enterprise virtual infrastructure platform is now free (including resource pooling and live relo), and we have announced Citrix Essentials for XenServer, and Citrix Essentials for Hyper-V as our virtualization management portfolio that offers a rich set of automated functions that drive the compatible virtualization layers beneath – the free Hyper-V hypervisor from Microsoft, and the free XenServer Enterprise virtual infrastructure platform from Citrix.  Finally, and most importanly, we announced a powerful go-to-market roadmap with Microsoft.

The eqivalent of Citrix’s XenMotion – which can migrate a live virtual machine to any other XenServer host running in the same resource pool without downtime – in the VMWare world is a pretty $4-6K investment. Not a bad move considering VMWare is about to do its VMWorld Europe 2009 show soon.

From the product site, a direct comparison:

Features included at no cost Citrix XenServer VMware ESXi
Bare-metal hypervisor 64-bit 32-bit
Max virtual CPUs 8 4
Windows® and Linux guests
Unlimited servers, VMs, memory
P2V & V2V conversion
Shared SAN and NAS storage
Centralized multi-server management
Resilient distributed management architecture
Live motion
Shared VM template library
Centralized configuration management
Virtual infrastructure patch management
Intelligent initial VM placement
Intelligent server maintenance mode
Fine-grained CPU resource controls
Hot-swappable disks and NICs

Virualization.info has an interesting look at the move and what it may mean. Otherwise, go grab your copy.

Direct download links appear below:

Base Installer [296Mb] (MD5)
Linux Guest Support Installer [245Mb] (MD5)
XenCenter for Windows [6Mb] (MD5)

Enjoy!

The anatomy of the Ext4 File-System

February 23rd, 2009 No comments

Tim Jones has posted an article on the IBM DeveloperWorks website about the importance and anatomy of the Ext4 file system for Linux.

The first supported file system for Linux was the Minix file system. This file system had some significant performance issues, so another file system was created specifically for Linux called the extended file system. The first extended file system (ext1) was designed by Remy Card and introduced into Linux in April 1992. The ext1 file system was the first to use the virtual file system (VFS) switch implemented in the 0.96c kernel and supported file systems up to 2 gigabytes (GB) in size.

The second extended file system (ext2), also implemented by Remy Card, was introduced in January 1993. It adopted advanced ideas from other file systems of the day (such as the Berkeley Fast File System [FFS]). Ext2 extended supported file systems of 2TB in size, although 2.6 kernels extended the maximum size of ext2 file systems to 32TB.

The third extended file system (ext3) was a major advance in Linux file systems, even though its performance was less than some of its competitors. The ext3 file system introduced the concept of journaling to improve the reliability of the file system when the system is abruptly halted. And although competing file systems had better performance (such as Silicon Graphics’ XFS and the IBM® Journaled File System [JFS]), ext3 supported in-place upgrades from systems already using ext2. Ext3 was introduced in November 2001 and implemented by Stephen Tweedie.

Fast-forward to today. We now have the fourth extended file system (ext4). Ext4 introduces numerous new advancements for performance, scalability, and reliability. Most notably, ext4 supports file systems of 1 exabyte in size. Ext4 was implemented by a team of developers, led by Theodore Tso (the ext3 maintainer), and was introduced in the 2.6.19 kernel. It is now stable in the 2.6.28 kernel (as of December 2008).

Ext4 borrows many useful concepts from a variety of competing file systems. For example, the extent approach to block management had been implemented in JFS. Another block management-related feature (delayed allocation) was implemented in both XFS and in Sun Microsystems’ ZFS.

Well worth a read as it covers some of the significant changes and updates made to Ext4 and how it differs from previous releases. I’m using XFS on my file server eagerly awating the arrival of Btrfs.

Victorian Bushfire Appeal

February 22nd, 2009 1 comment

Today marks a day of remembrance for the worst bushfire season we’ve seen in Victoria – ever. Beating Ash Wednessday and Black Friday. Whilst I was away, more than 1800 homes have been lost and more than 200 people have perished in what seems includes several deliberately lit fires.

Fires raging on

A bushfire burns through a forest on the outskirts of Labertouche, 90km (56 miles) east of Melbourne February 7, 2009.

Please consider donating to the Victorian Red Cross – Bush Fire Appeal 2009, you can donate online from anywhere in the world. Currently (as of 22/02/2009) there are still fires raging throughout regional victoria:

More images, videos and articles of the devastation is posted as a slideshow and full coverage is available on The Age website.

Update:

Detailed bushfire information is available on the Department of Sustainability & Environment website with maps of the affected areas available on the CFA website.

Weddings, Home-coming, Sri Lanka, Malaysia, Scuba Diving and coming home.

February 21st, 2009 3 comments

Well I’ve been a bit lazy with teh bloggin lately. I took two weeks leave to spend some time in the motherland (Sri Lanka) attending weddings, home-comings and visiting the relatives amongst a bit of chillaxing. I have to admit, whilst I haven’t talked much (openly) about the civil war, its clear that things are definately moving along.

Security is incredibly tight, the drive from the main airport down to my aunt’s house (and previously where we lived) in Moratuwa via Galle Road was incredibly tight. We got checked close to 5 times along the way – can’t be suprised really, I look real dodgy (with a wierd accent). Even at 3-4am (when we left the airport) every 200-300m there was atleast one army officer loaded awaiting any threat.

Drivers are recorded in a log – license/ID’s checked, passengers are also checked (in my case my passport was checked as I dont have a national ID card), sometimes they even checked our bags. Thankfully, in the time I was there, no issues occured. The majority of the people seem to have a chilled attitude about the war, hopeful for a brighter tomorrow and peace & harmony for all ethnic groups there.

However last night it seems the LTTE has managed to fly two planes and hit some targets in Colombo. Which is rather disappointing considering they are now tucked into a 90-100 square km block.

Right now, I’m sitting at KLIA inching towards boarding time, so I better run off.
