The article is named, “Don’t be ugly by accident” and brings up a few points about why different types of cameras can make you look better, as well as the time of day and focal length of the lens used.

Doesn’t really make a scientific point, but an entertaining post nonetheless.

Vista_on_Win2000_2003

Using Group Policy, you can manage when Vista and 7 computers hibernate, go to sleep, and many other options.

This can be used to either keep your computers from going into sleep modes to prevent problems (like I’ve experienced with brand new Dell Optiplex 380′s that wouldn’t wake up properly) or can be used to help save your organization money by powering off computers after certain periods of inactivity.

The document comes from energy-star, and is aimed to help you save electricity, thus saving the environment, but you can use the same instructions in a different way to keep your computers running all the time as well.

The basis of the problem is that Windows Server 2008 (like Windows Vista) gives precedence to IPv6 over IPv4 and this is especially a problem if you have your mailbox and CAS on the same server (the normal default configuration).

Really nice forum for discussing security in your home, office, or wherever.  Everything from security cameras, alarms, and monitoring services for both novices and professional installers.

And a funny BAD story about home security from a service tech:

Only $65.10 for 1000′ Solid Cat5e cable, which isn’t too bad.  I see they have all kinds of stuff for ‘wired’ homes as well.

How to use VLAN’s to separate network traffic on the same logical LAN

Link Aggregation is also referred to as Port Trunking, Port Teaming, Ethernet Trunking, and Link Bundling.  Cisco has a a multi-port proprietary technology known as EtherChannel.  All refer to the same concept; multiple ports acting as a single connection between network devices.  The key to setting up Link Aggregation between different brands is ensuring they both support the IEEE standard 802.3ad.

The value to Link Aggregation is that the two switches will treat multiple ports configured in a Link Aggregate Group (LAG) as a single trunk, providing increased total bandwidth, as well as redundancy.  If two ports are configured as a single LAG between two gigabit switches, there will be two Gbps total bandwidth between the two switches (1 Gbps in each direction).

This post should help those struggling to realize the concept of having multiple external IP addresses registered to a single modem.

I’m currently in the process (after a year or so of waiting for my employer’s to get ready for this) of setting something like this up to have two web servers behind one Comcast modem.

We will be hosting an Exchange Server and a Moodle site from two separate servers using just one modem.

You may or may not have the same setup as this guy, but the poster’s give the basics of what you need and how to go about this type of setup.

Have fun!

*Edit*

I have completed my setup at my employer’s location.  I replaced their sonicwall as the router and put in an Untangle box as the replacement.  That made it easy to setup the additional IP’s as aliases, and create forwarders for the additional Internet IPs > Internal IP’s.

Now, they have two fully functioning websites running on a single cable modem using SNAT or 1:1 NAT.  It was quite easy once I had the IP’s actually configured on the modem.

Check out this site if you’re interested in placing some home automation tools, such as light switches, water valves, window / door sensors, or maybe things like home servers or home security cameras.

Most things can be accessed from anywhere in the world, plus the added bonus of sharing certain devices out to friends and family. So, if you’re a photographer (or a wannabe), you can easily share out your photos to friends and family from your own home server.

Water valve busts in your hose while you’re away? The Z-Wave valve can automatically shutoff water to your home, and send you an email and SMS message of what happened, and tell you that it shut off the water to prevent costly repairs (all while you’re not even home!)

Pretty slick stuff!
