AT&T Kills Unlimited Data for iPhone/iPads and Why You Should Switch NOW before it’s too late!

I knew these B-tards(AT&T) were up to no good when they first started out as Cingular, they kept sending me a bill for a quarter.  Of course, I didn’t pay because I knew it cost them 29 cents for postage to send me bills every month.

Anyways, AT&T = evil, a company that offers dropped calls, bad 3G data service, and now finally the first company to introduce new data plans to millions of people who’ve already purchased “unlimited” data plans when they bought the phone.

USB Hack – How to Make a CPU/Hard drive/Memory/Network Monitoring Device!

For those of you running highly-intensive game servers or even web servers, here’s a really interesting device that will let you monitor CPU, hard drive, memory, and network usage through an analog meter.

This is a fantastic project for anyone who wants to build one, there’s free C# code and schematics provided.

The USB Performance monitor is a PIC18F2550 based

AT&T Problems Pointed Out by New York Times!

The other day I told you some solid reasons why you should boycott AT&T like me since 2006, well I just found some facts to prove my point including writer on New York Times saying AT&T is simply SLOW:

Ethernet DIY – How to Make an Ethernet-Enabled Cat Feeder!

Personally, I have worked with many cool ethernet projects and by quick look, this one is pretty complicated yet will let you feed your cat over the internet, no matter where you are. (even if you are in China!)

The author uses a hacked Cisco router and some custom-hacked circuit to feed his cat plus added some video monitoring system:

Broadband Still Lacking in the U.S.!

I have to admit, my Comcast cable DSL is pretty darn fast, fast enough for me to get things done but it’s never fast enough as the fiber-optic networked 300Mbps that virtually every household in South Korea is getting.

Every year, I talk to one of my friends in South Korea.   3 years ago, I asked my friend, “so, how fast is your internet now?”  He replies, “I get 100Mbps at my apartment, they’ve got fiber-optics connected to the central network in Seoul.”

Couple days ago, I asked my friend again the same question, he replies, “I get

What is HDMI and What is DHCP?

LOL, I got these 2 questions from one of my Laptop Blog readers:
