I just recently graduated from the electrical and computer engineering program at Carnegie Mellon. The IT policy was pretty solid, open to all platforms, no headaches. Data integrity and personal privacy are held very highly. Student data stored on CMU servers may not be access unless there's an emergency, or if there's a valid warrant.

Getting caught by the RIAA/MPAA/BSA with copyright violation gets you 45 days loss of connectivity on that MAC address, but there's a solid intra-CMU file sharing network.

Plenty of bandwidth available to students (average 1-3MB/sec up and down -- yes, megabyte). Limited to rolling average of 2GB up/down a day over 5 days for wired connections. 750MB for wireless.

Because it could be really, really cool. As an engineer I like "hard" problems, and when I find a project interesting I go after it -- regardless of how "flashy" it is to the general public.

I think in Google's case, this is certainly true if you examine how much work has gone into their infrastructure (and how many research papers have been written on those topics).

Data Storage

+ - RAID vs. JBOD vs. Standard HDD's

Ravengbc (1013269) writes "Hey everyone, I am in the process of planning and buying some hardware to build a media center/media server. While there are still quite a few things on it that I haven't decided on, such as motherboard/processor, and windows xp vs. Linux, right now my debate is on storage. I'm wanting to have as much storage as possible. At first I was thinking about just putting in a bunch hdd's and leaving it at that. Then I started thinking about doing a RAID array, looking at RAID 5. However, some of the stuff I was initially told about RAID 5, I am now learning to be not true. Such as, RAID 5 drives are limited to the size of the smallest drive in the array. And the way things are looking, even if I gradually replace all of the drives with larger ones, the array will still read the original size. For example, say I have 3x500gb drives in RAID 5 and over time replace all of them with 1TB drives. Instead of reading one big 3tb drive, it will still read 1.5tb. Is this true? I also considered using JBOD simply because I can use different size hdd's and have them all appear to be one large one, but there is no redundancy with this, which has me leaning away from it. If y'all were building a system for this purpose, how many drives and what size drives would y'all use and would y'all do some form of RAID or what? Also, if anyone has suggestions on motherboard/cpu thoughts, I'm open to suggestions. Thanks guys."

+ - GTA IV Delay Possible, Says Patcher

Anonymous Coward
Anonymous Coward writes "Wedbush Morgan analyst Michael Patcher has speculated that publisher Take-Two may delay the release of Grand Theft Auto IV until 2008, as a means of improving the company's financial earnings. Although the game, due out on Playstation 3 and Xbox 360, is scheduled to ship on October 16th, Patcher believes "that it is possible that the company will choose to "throw in the towel" on financial year 07 by shifting the release date for Grand Theft Auto IV by a few weeks, increasing the losses incurred this year and improving the company's prospects for financial year 08.""

Now take a look behind the scenes with Network Performance Daily as we interview Jason Potkanski, the sysadmin behind the project who kept things running on the "Domestic Tension" project when the site was in over it's head.

From the article: "At one point, the traffic was so heavy that it literally set the DSL line on fire. First, a funny smell came from the consumer-grade router, which was fixed through power cycling. It simply couldn't handle the IP table with thousands of clients. Then the wires for the DSL/Ethernet ran up the wall by Wafaa Bilal's desk "in the conflict zone" and the paint from the paintballs leaked down the walls into the basement and onto the DSL line."

Wii

+ - What could the Wii do with controller calibration?

Submitted by Phoenix00017
Phoenix00017 (1017168) writes "This question originally started as frustration about the fact that I can't calibrate my aim for the Wiimote (which is very annoying for any lightgun-like games). I know there are some clever physical hacks that allow you to do this, but why not just put it into software? But then this opened up a second question — since we have 3D accelerometer data, if we are given a calibrated "starting point", can we not know the exact 3D orientation and position of the Wiimote at any point in time? If, say, Wii Baseball told you to hold the bat straight in front of you and hit "A", would we then be able to track exactly when you swing, as opposed to just flicking your wrist in any direction? Would this not allow for much more immersive gameplay? Are there any games doing this? Or is there a flaw in my logic?"
Wireless Networking

coondoggie writes "With all of the electronic gadgets and components in cars and trucks these days is it possible they could become mobile wireless network nodes too? That's the idea behind a project at UCLA that uses about $1,000 of wireless technology deployed in cars which enables them to act as nodes in a truly mobile network. UCLA Engineering's Network Research Lab is looking at using cars to form a communications network based on the principles of technology known as a mobile ad-hoc networking platform, or MANET. The MANET platform lets moving vehicles within a range of 100 to 300 meters of each other to connect and, car by car, create a network with a wide range. As cars fall out of range and drop out of the network, other node-equipped cars can join in to receive or send signals. http://www.networkworld.com/community/?q=node/1586 1"
