Sometimes words encourage you to think and to look beyond the everyday life – to understand that we are just but a nuance in the vast cosmic arena. They make you feel humble yet not any less hungry to understand more of our world and universe. The videos below are such a force of this feeling and I hope you can spend a few minutes of your time to listen to them. They’d hopefully give you a perspective of life as they have given me.

I recently stumbled upon a youtube clip where Sir David Attenborough eloquently talked about the issue of the growing human population. About six years ago I also wrote about this very same issue. It’s one thing to read something from a person like me, but it’s a total different thing to listen to a knowledgeable and highly intellectual person like Sir David Attenborough. In this clip Sir David touched on many issues regarding the fundamental causes, consequences and solutions to this alarming problem.
In my earlier post Netgear WNR 3500l v2 with Tomato firmware, I wrote how to install a third party firmware calls Tomato on the Netgear 3500l v2 router. Tomato firmware enables many features that often are missing in the stock firmware. One of the feature that I think is pretty awesome is the ability to create a virtual WLAN. A virtual WLAN is also often being called as “Guest WLAN” on many new and advanced routers. Usually it is a feature that you just turn on and magically you get a new WLAN (SSID) that your guests can you use.
One of the basic but also the most important services an IT-department has is the helpdesk. From my experience many IT-departments use (bare) e-mail as the helpdesk system. E-mail does work to some extends, but comes short when you want to have a good overview of the incidents. Often it is hard to know which incident has assigned to which technician and what the technician has done in the life of that incident.
One of worst things that could happen to a receptionist is unwanted visitors – especially those that could pose a threat. The organization I’m currently employed at was facing this issue and I was tasked to create something that the receptionist can use to alert people in the organization. To solve this task I refreshed my programming skills and created a small and simple application in .Net framework using C#, that will send SMS and E-mail to the people of choice when the user clicks on a “panic button”.
With Virtualization being more and more widely used by big and small companies alike, Microsoft has stepped into the competition with their own virtualization solution – calls Hyper-V. Hyper-V was introduced with Windows Server 2008R2, but because of its immaturity and lack of advanced functions, it never managed to compete with VMware. However with the release of Windows Server 2012, Hyper-V has become a more mature product (check the comparison) and offers, to some extends, the same features as VMware but at a lower price tag, compared to the more expensive VMware licensing cost.
One of the cool things about routers nowadays is that one could replace the stock firmware with something else. The incentives for this is to get features that the stock firmware lacks. VPN-server, VLAN, advanced routing and WiFi-boosting are a few things that usually lack in stock firmware, but can be obtained with a 3rd party firmware.
This is a followup to my previous posts VMware project part 1 and VMware project part 2, where I wrote about how to set up an ESXi 4.1 hypervisor on a “non-supported” hardware, also referring to as whitebox. Instead of using local harddrives as storage for the ESXi we can use storage from a network using a protocol calls iSCSI. iSCSI is usually being used in enterprise in conjunction with a SAN (storage area network). There are also some NAS-boxes that offer iSCSI target right from the box. But in this howto we’ll be focusing on how to set up our own iSCSI target on a Linux box and connect it as storage to the ESXi hypervisor.
