evilrouters.net » ARIN Regains 45/8 from Interop This is a nice move. Doesn't solve the problem, just delays it, but still. As I've said for the last couple of years, if you aren't looking at IPv6, even in a research mode, you are way behind.

The Spinning Disk’s Stay of Execution | virtual insanity Good description of what Xiotech does in their arrays that make them pretty sweet. One thing they don't note is cooling — because the disks counterrotate they end up having backplanes on both sides of a 3U disk unit. This means a nice big hole down the middle of the disk pack, and air can be circulated slowly down the center instead of the standard high-velocity fan setup, needing to push air around a backplane. Cool (pun intended). New CPR is spelled C-A-B – CNN.com So the new guideline is to forget rescue breathing in CPR and just start compressions. That's a big change but it makes sense.

Ten Essential Tools for Linux Administrators | LinuxTechCrunch | Linux Software | Linux Software Download | Linux Software Tutorials This came through via the Nagios community. Nagios is #7 on the dumbest list of tools ever. Nobody in their right mind would put Nagios, a useful tool every day, in the same list as Gparted (which you’ll use once or twice a year, tops), Webmin (no self-respecting Linux admin uses Webmin), or Byobu (WTF, an app that tells you your OS version? You don’t know that already?) [UPDATE: Check the comments, Byobu isn’t what this article describes it as]. A list built by people who know nothing about Linux, for sure. Tiger Woods gives us the greatest golf photo you’ll …

Research Shows Radiometric Dating Still Reliable (Again) A previous link of mine, a month ago, was about how it seemed that the half-life of nuclear isotopes seemed to change based on the sun's output. Now others have ruled part of it out. I suspect we're not done with this debate, especially since we need to figure out exactly why some people thought it did change. I do like the quote: “There are always more unknowns in your measurements than you can think of.” VMware KB: SCSI Reservation Conflicts when using OpenFiler iSCSI Storage Devices Moral of the story is: OpenFiler doesn't work as iSCSI storage for VMware. Nor does anything using the IET. VIDEO: Blackhawk Almost Down in Lake Tahoe …

Disk Performance of a 16-drive Dell PowerEdge R910

You can order Dell PowerEdge R910s with as many as 16 disks attached to the H700 controller. We did. Since it’s hard to find benchmarks out there for what you can expect out of local storage performance I ran a few tests on it. I didn’t have a whole lot of time to run a comprehensive set of tests, as the box wasn’t mine and it needs to get deployed, but I was able to get some basic performance statistics. These tests were conducted with the integrated H700 controller, running firmware 12.3.0-0032 A02. That controller has 1 GB of NVRAM cache on it, and in each test case the container was set to the default stripe element size of 64 …

VMware KB: Installing TCP/IP in Windows 95 You have got to be kidding me. If you need this explained to you you should not be in IT, nor anywhere near a virtual machine. Brainfuck – Wikipedia, the free encyclopedia "The brainfuck programming language is an esoteric programming language noted for its extreme minimalism. It is a Turing tarpit, designed to challenge and amuse programmers, and is not suitable for practical use. Its name has been variously bowdlerized. The name of the language is generally not capitalized, although it is a proper noun."

Whats the difference between kbps and kBps ? A lot. – My Etherealmind You can tell that science education is missing from most countries nowadays, just by the carelessness shown with units. Some vendors confuse this, too. A factor of 8 is a big deal in most calculations, at least if you care about the result.

Networking Tech Field Day

Events, like people, have lifecycles. They are born, they grow up, they die. With Gestalt IT’s latest event, a networking-specific gathering in the heart of Silicon Valley, Stephen Foskett’s idea of a blogger-centric vendor tech gathering is becoming a teenager. It’s pretty much fully-grown, has its drivers license and a lot figured out, but it still has some awkward social moments, and even has to deal with obnoxious schoolyard bullies. I count myself incredibly fortunate that I’ve been invited to two of these events. The first was the Tech Field Day in Seattle, focused on storage. This one, the sixth Field Day, was on networking. I found myself surrounded by battle-hardened networking gurus, outnumbered 11 to 1. Daunting, sometimes, but …

San Antonio brothers threaten to sue Storyville, claim to own “Who Dat” – The Storyville Blog This is mega lame — "Who Dat" has so much prior art this can't succeed. But it's Louisiana… Hmm… Project OpenIndiana While I admire the dedication to the platform, is it worth the time? Will anybody but a few hobbyists use it?
