Linux Scripts to find Public IP Address

In some cases, you may need to know your public IP or the public IP of a server behind a NAT (e.g. for remote SSH login) if the IP is assigned dynamically as is the case for PPPoE connections. Here are several ways to find your public IP in Linux using the shell. 1. Using curl (almost too simple) curl -s http://www.whatismyip.org 2. Using wget wget -q -O – checkip.dyndns.org|sed -e ‘s/.*Current IP Address: //’ -e ‘s/<.*$//’ 3. Using lynx lynx -dump checkip.dyndns.org If you have access to a web browser, you can simply use http://www.whatismyip.org, http://checkip.dyndns.org or http://www.moanmyip.com.

Sony NSX-24GT1 Google TV Tear Down

Nikkei Electronics has recently teared down Sony Google TV as seen at IFA 2010. They used Sony NSX-24GT1, a 24″ internet HD television powered by Google TV, for this little exercise. They found three boards: Power supply board at the upper left. Main board (“Android board”) at the lower left. TV board at the right. The SoC mounted on the TV board is Renesas Electronics Corp. EMMA3TL2 (MC-10157), an image processing SoC designed for digital TVs supporting ATSC (USA), DVB (Europe) and ARIB (Japan). Finally, they disassembled the TV to access the main board. It turned out that Sony NSX-24GT1 Google TV main board is based on Intel Atom CE4100 (center) and Foxconn is the manufacturer (lower right). Eight Samsung K4B1G0846F DRAM modules are mounted on the board (Right of Atom CE4100) and since each of the DRAM has a capacity of 128 Megabytes, the total memory capacity is 1 Gigabyte. The “Android” board receives the video data from the …

ARM Techcon 2010 Proceedings and Presentation Slides

A lot have been covered at ARM Techcon 2010. I’ve blogged a few articles about ARM Techcon 2010, but there is a lot more to discover. A full set of documents and presentation slides shown at Techcon 2010 are available at http://vault.eetimes.com/armconference/proceedings/ The documents are divided in 2 main parts: Day 1: Chip Design Conference Day 2-3: System & Software Design Conference which are then divided into sub-directories with really (hmm) good names such as ATC-100, ATC-101… to ATC-165 so that everybody can clearly see what the subjects are. You’ll also have the Keynote and Industry addresses. Since this blog is more related to “System & Software Design” I’ve been through the pain of downloading all documents of this section and checking the subjects. You may do it for “Chip Design Conference” if you wish, I’m sure you’ll enjoy it. You’ll have one or two documents in each folder. If you have two, most of the time there will be …
