"I see in the near future a crisis approaching that unnerves me and causes me to tremble for the safety of my country. . . . corporations have been enthroned and an era of corruption in high places will follow, and the money power of the country will endeavor to prolong its reign by working upon the prejudices of the people until all wealth is aggregated in a few hands and the Republic is destroyed."

"I claim that Mach people (and apparently FreeBSD) are incompetent idiots."
I'd imagine that a compentent idiot is one who's smart at being stupid. A incompetent idiot is someone who's not smart at being stupid. That would make them simply smart.
I'm highly annoyed at the fact that there are even plans for different tiered versions of one operating system. It's really, really lame to restrict a users ability to use his own hardware by the OS that's running on it. Essentially, that's what these OSes do. The OS's job is to manage the hardware in that box and allow it to be used to it's full extent, and not limit what you can do with the hardware you have purchased. This is the same reason that Linux is actually useful on a 486 or P100 and versions of Windows are not.
Heh, and then Google will save all of your corporate emails to their servers... Is that what you really want? Sure they are a great search engine, but obviously Google has breached user privacy by saving our searches and implementing these "new" features in Google Desktop. The last thing I'd want them to do is save my private, corporate emails to their own servers for whatever reasons..
I think the fat should be cut from the top. We have the largest CEO to entry level worker wage ratio. It's pretty ridiculous compared to other industrialized countries that are doing just fine.
I can bet you most universities don't even teach "goto" logic and if they said anything about it, it was: don't use GOTO statements. There was no mention of it in my university classes at all. I remember being told not to use it my high school computer science class. Ha..
"Office Live will come in both ad-based and subscription versions that augment MS' Office suite." How many times will I have to pay for my software? This is a horrible idea and consumers need to be made aware that "bigger and better" is hardly better and is usually filled with useless features. On that note, Office 2000 works fine for me. It already has tons of features I have never used.
Who says we NEED all of these new expensive gadgets? Just because "bigger and better" exists does not mean I need it. "Modern society corrupts" -Rousseau
Aye... Getting 100 dell pc's with the exact same hardware settup makes unformity a a breeze. Spend time on one linux OS and customize how you like then ghost those suckers multicast baby!
Blogs are fine. At least you are not forced to read them. If you do go to someone else's website, it is through your own volition only. Blogging is fine. It's your fault if you subject yourself to someone else's misery online.
Also, switches typically use methods to check for frame errors. "Cut Through" and "Store and forward" will be typical switch forward methods. I believe there is one more, but I can't remember it off the top of my head. Store and Forward will check the CRC section of the frame for errors which slows switches down even further than hubs. Cut Through does no checking of the CRC for frame errors.
Hubs do have a lower latency than switches. If you're familiar with the OSI model, you'll find out that a hub is a Layer 1 Device that deals with simply 0s and 1s. A switch is a Layer 2 Device that deals with hex MAC addresses. The simple fact that a hub does not have to look up a switch port address in the CAM (content addressable memory) table to decide what port to forward a frame makes it much faster than a hub. By design, hubs are technically faster than switches. At the same time, for a large number of PCs (over 25~) or so switches are faster because they will prevent network collisions due to the fact that switches seperate collision domains and hubs do not, in that respect. Seperate collision domains will drastically lower the rate at which a NIC will need to run the CSMA/CD back off algorithum when it sees that another NIC is trying to transmit data on the wire. CSMA/CD back off algorithum selects a random number of milliseconds for the NIC to attempt a retry to send its data.
The real issue with these kinds of routers is the fact that the cable/dsl modems themselves are not interactive once their data queue becomes filled. Sure, traffic shapers are execellent and I've read http://lartc.org/howto/ which has great information for linux. Cable/DSL connections are asymetrical, and when you send data from your pc to the actual cable modem, you send it at 10/100megbit (whatever speed the nic in your pc and cable modem agree on) Your ISP will limit you to 512kBit upload for example. The modem cannot send data to your ISP as fast as you can send it to your modem thus the data queue fills very fast and your modem has trouble keeping up. These shapers can simply slow down the rate at which your PC sends data to the modem and thus stopping the filling of the data queue in the modem which will allow it to be more interactive. That is the biggest problem you'll have with cable/dsl connections for a few users. Sure, more detailed protocol based shaping can and should be used to reserve bandwidth on a larger scale.

Maybe we're throwing away billions of dollars in a foreign country when we could be concentrating on domestic issues.

I'm just going to get rid of my analog TV and go back to doing what I did in college... READ BOOKS.

Nowadays, a new version of MS Office may as well be equal to a new version of WinZip. Ha!
