Submission + - New Air Conditioner Process cuts energy use 50-90% (nrel.gov) 2

necro81 writes: The U.S. National Renewable Energy Laboratory has announced that it has developed a new method for air conditioning that reduces energy use by 50-90%. The DEVap system cools air using evaporative cooling, which is not new, but combines the process with a liquid dessicant for pulling the water vapor out of the cooled air stream. The liquid dessicant, a very strong aqueous solution of lithium chloride or sodium chloride, is separated from the air stream by a permeable hydrophobic membrane. Heat is later used to evaporate water vapor back out — heat that can come from a variety of sources such as solar or natural gas. The dessicants are, compared to typical refrigerants like HCFCs, relatively safe for the environment.

If you are old enough to attend college/university you are old enough to do whatever you want.

Wrong on so many levels.

If you attend a college or university, chances are you are held to a standard of behaviour that prevents you from making the learning institution look like a fool.

Admissions papers are full of "Sign here on the X", one of them was your agreement to not be a jackass and accept the college's rulings on your behavior.

Don't like it? There's the door.

Comment Re:Is this how they can do wifi location detection (Score 1) 237

It's all based on your AP's mac address. You can change your ssid and you ip will change (DHCP) but the one thing that will remain is the MAC address of your wifi access point.

As the googmobile drives through your hood it knows where it is by GPS. It's listening for wifi data to capture the mac and tag it with the gps. Then as it picks up more data, it's able to provide a more accurate location based on wifi traffic.

Quite ingeneious, labor intensive, and completely legal.

As people upgrade their gear or move - this data will get stale. I wonder if google plans on maintaining this?

Books

Drupal 6 Attachment Views 35

Trevor James writes "Green's book is without a doubt the definitive practical guide to using the Views 2.x module in Drupal 6, and to creating complex and dynamic page, block, and attachment-based views for your Drupal site. One big plus to this book's structure is that Green uses a real "live" production website project as a guide (he states early on that he was working on the site build for the client while writing the book and that the client approved of using the site build as the book's main example) — all of the chapters and subsequent tutorials are focused on building a site for a company that specializes in hiring out contractors and subcontractors. It's nice to see real-world examples being used in a computer tutorial book, especially one focused on Drupal and Drupal Views. The data Green is accessing is real data and this helps to engage the reader and show the multitude of real situations that a developer will get involved with when developing Drupal Views." Read on for the rest of Trevor's review.

Your wifi is sending everything you do 300' (more or less) in all directions. Encrypt it or STFU.
and if it bothers you that one of Google's cars drove by and snagged your wifi access point's name then stop broadcasting your SSID too.
Just because you don't understand how to configure your wireless network correctly gives you know rights to sue someone. Or at least win in court.

You think IT want ie 6?! No were the ones that have bitching to management for the last two years to approve the rollout. But they say we can't until HR's ancient reporting tool is upgraded to work with IE8, but there's no money in the budget for that again.

So don't fucking poke me and leave my retro phone alone.

Seriously, you can't buy this kind of publicity.

Sure, you have to leak your product - but what the hell.. nobody will suspect it. Then sue the shit out of the guy who published photos - even more press time when it goes to court.

Then on the day of the release... drop the charges so you don't look like a huge asshole.
