Citrix has released Xenclient. A hypervisor designed to run on Laptops. There’s some excellent arguments for doing so in a corporate environment. I just read a nice, concise overview of Xenclient at Standalone Sysadmin

No it’s not open source but it is available for both Linux and Windows.
IncentivesPro make a product I recently used for a Virtual Desktop Thin Client Implementation. That is USB Redirection for Remote Desktop. It uses a proprietary client/server and so I used Windows XP embedded thin clients to redirect specialised USB Thermal Laser Printers to the Vista Virtual Machines. The website looks a bit underwhelming but the product is flawless and it’s priced much better than their competitors. If you have more time than I did, it’s likely you …

Pluf is a PHP Framework developed as a port of Django to PHP. It claims to be simple, elegant and easy for people used to Django but in PHP5 so easy to deploy all over the world.
After reading the documentation, the file layout and concepts are all quite similar to django, though a downside is that we lose much of the beauty of the Python language and it doesn’t seem to have the Admin interface that makes django so delightful to work with.
Here is a sample of a helloworld, which …

Linux Administration, Unix & Solaris, Virtualization (Virtualisation) »

Some really bizarre results here that just blew my mind. Check out the “rate” column for both random writes and random reads and compare the Ext3 Ubuntu with Nexenta VM for both UFS and ZFS – UFS is a bit quicker the ZFS. I am not sure whether the virtualisation actually improves the random reads and writes but it’s a pretty massive difference. After my small play with Nexenta, it’s looking quite promising to become my primary desktop OS.
Here’s a tiobench of Ubuntu 7.04 running on a Seagate ST3320620AS 320GB …

Is it just me or is this the year of open source? That ever elusive “year of Linux” may not arrive but certainly, it seems the virus of open source is taking hold. It certainly is happening in the kind of Web2.0 projects we are seeing coming up, and many businesses are choosing open business models of traditional models. Green is in, Green is good and open source is along for the ride. Or is it that suddenly because I am kind of focused on Open Source technologies, it starts …

Rant, Virtualization (Virtualisation) »

Today, I tried to organise some VMware licenses for a customer who was running the ESX Starter Pack. Both my customer and myself were never aware that

To upgrade from ESX 3.0 Starter to Standard or Enterprise, you have to be an ‘Enterprise Partner’
To become an Enterprise partner, you need to pay US$1000 and ALSO
You need to have a Vmware Certified Professional as an employee

Did I get that right? They won’t sell me their product unless I get a VMware Certified Employee? That can’t be right.. come to think of it, …

I recently stumbled upon this very interesting interview with (ex) Linux kernel developer Con Kolivas. The article is definitely worth a read as Con expresses much of his frustrations with the performance of the Linux kernel for desktop users (much of it relating to scheduling) as well as some of his frustrations with the kernel development process.
I know myself that FROM A USER’S PERSPECTIVE, very high disk i/o can kill a HP DL-585 with 5 x 15K SAS drives, meanwhile the same task running on a lower end HP9000 …

FreeNX & NoMachine, Internet Goodness, Virtualization (Virtualisation) »

[21 Jul 2007 | 2 Comments | ]

Something that was not obvious to me when using NX client was the ability to get out of fullscreen. I initially thought that they just hadn’t implemented it as yet.. but we are now on version 3 and I thought that the mere oversight should have been fixed by now.
Well, I don’t know if it has always been there but there’s two ways to switch between the remote desktop session and your local session when using NX
You can switch between full-screen and your original desktop by clicking on the …

Wow.. a great week it has been in the enterprise Linux world.
Last week, we had:

Mindquarry 1.1 released
TinyERP released a web client and a new version
OpenBravo 2.30 released

and while it’s not truly open source, NoMachine released V3 of their NX server and finally, they have introduced
desktop sharing and session shadowing

Now, if your an admin, it’s a no-brainer to set it up – you can either do it from NX Manager (make sure you have V3 also) or you can edit /usr/NX/etc/server.cnf
You can checkout all the directives from the Admin guide …
