For the impatient, here is our simple script. We’ll explain it afterwards. This is assuming that you’re on a 192.168.1.0/24 network with no DHCP server.

Is VMware’s dominance of the virtualization market under threat?
But VMware has dominated the virtualization market for so many years that the massive shift found in the survey may take longer than expected, if it happens at all. The virtualization layer, primarily composed of VMware software, has so many hooks into security, backup, automation, disaster recovery and various management tools that swapping hypervisors is no simple matter, argues an analyst who read the results of the survey, but was not involved in conducting it.
via Is VMware’s dominance of the virtualization market under threat?.
And here’s the conclusion.
VMware shops are certainly kicking the tires on Hyper-V and deploying it at least in test and development scenarios, and Microsoft is trying to lay the groundwork for both small businesses and enterprises to switch from VMware to Hyper-V. If 38 percent of businesses do change primary hypervisors within the next year, the folks in Redmond are likely to be the major beneficiary.

Full disclosure: I am an ex-PM on Google Reader, and I worked on comments and the last round of sharing changes. I also left Google in July.

I ended up clicking on this because I had no idea what Google Reader was. There might be some insight into CPE UI requirements in this rant.
HP Project Moonshot hurls ARM servers into the heavens
And while HP was not in a mood to talk specifics, Santeler said that Moonshot would include super-dense servers based on Intel low-power Xeon and Atom chips and Advanced Micro Devices low-power x86 processors as well as multiple suppliers of ARM-based server chips

Re-read The Partition Table Without Rebooting Linux System
partprobe command is part of GNU parted software. parted is a disk partitioning and partition resizing program. It allows you to create, destroy, resize, move and copy ext2, ext3, linux-swap, FAT, FAT32, and reiserfs partitions. It can create, resize and move Macintosh HFS partitions, as well as detect jfs, ntfs, ufs, and xfs partitions. It is useful for creating space for new operating systems, reorganising disk usage, and copying data to new hard disks.

Quagga Software Routing Suite
Quagga Software Routing Suite.
Quagga is a routing software suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPng and BGP-4 for Unix platforms, particularly FreeBSD, Linux, Solaris and NetBSD. Quagga is a fork of GNU Zebra which was developed by Kunihiro Ishiguro. The Quagga tree aims to build a more involved community around Quagga than the current centralised model of GNU Zebra.
I’m not sure I want to support this. This is what Cisco et al. do and they do this very well. As a science project maybe but why would a small or medium biz need to do OSPF or RIP? I need to think about that question for awhile.

AWS Elastic Load Balancer sends 2 Million Netflix API Requests to Wrong Customer
When you deploy on Amazon Web Services with Elastic Load Balancers, you need to assume that random (untrusted) sources are reading client requests to your server (inbound traffic).

Oops.
Interesting discussion about this over on Slashdot.
