Power Lost: A Better Way to Compare PSU Efficiency

URL: http://www.silentpcreview.com/A_Better_Way_to_Compare_PSU_Efficiency

CA_Steve, an active member and a moderator in the SPCR forums, examined the 80 PLUS definition of efficiency as a % figure at different power levels, also defined as a % of the rated power of a PSU, decided that it is too misleading and shows why power lost (as heat) is a better efficiency comparison tool. I've had the same thoughts for years, but Steve took the extra step of data-mining my/SPCR PSU reviews for the past half dozen years to demonstrate the above, and show various power efficiency trends and issues relevant for not only Silent PC enthusiasts, but anyone with a yen to minimize energy consumption.

How an Internet-connected Samsung TV can spill your deepest secrets

A frame from a video demonstrating how Samsung TVs can be remotely commandeered.

ReVuln

If you use a Samsung "Smart TV" that's connected to the Internet, there's a good chance Luigi Auriemma can hack into the device and access files stored on connected USB drives.

The researcher with Malta-based security firm ReVuln says he has uncovered a vulnerability in most Samsung models that makes it easy for him to locate their IP address on the Internet. From there, he can remotely access the device and exercise the same control someone in the same room would have. That includes gaining root access and installing malicious software. The attack exploits bugs in features that allow end users to install Skype, Pandora, and other types of apps. The TVs can be controlled using smartphone and tablet apps and in some cases by voice commands.

"At this point the attacker has complete control over the device," he wrote in an e-mail to Ars. "So we are talking about applying custom firmwares, spying on the victim if camera and microphone are available, stealing any credential and account stored... on the device, using his own certificates when accessing https websites, and tracking any activity of the victim (movies, photos, music, and websites seen) and so on. You become the TV."

Specs leak for 13W, 10W Ivy Bridge CPUs

URL: http://feedproxy.google.com/~r/techreport/articles/~3/QHBlhgXtd8k/24019

Remember that rumor about Intel rolling out some lower-wattage Ivy Bridge CPUs ahead of the Haswell launch? Well, the folks at VR-Zone Chinese have gotten their hands on what looks like an Intel PowerPoint slide with specs for five new Intel processors—and their TDPs are as low as 10W. Ooh...

Apparently known as the "Y" series, these processors will show up in the first quarter of next year, according to VR-Zone. At the low end, the series will include a Pentium 2129Y with ...

Foscam FI9820W: how to enable telnet access

If you have the Foscam FI9820W, you can access it through telnet:

http://www.openipcam.com/forum/index.php/topic,419.0.html

Then you can install TinyFTP server:

1) download cross compiler to compile it for ARM:
http://landley.net/aboriginal/downloads/binaries/cross-compiler-armv5l.tar.bz2

2) download TinyFTP:
http://sourceforge.net/projects/tinyftp/

You just have to edit the Makefile to point to the cross compiler (where you downloaded)

CC=/home/fraga/src/cross-compiler-armv5l/bin/armv5l-gcc
CFLAGS=-mcpu=arm926ej-s

Then "make". It will generate tinyftp binary. You can through telnet download it from somewhere.

The syntax is simple and I created a script to run it everytime the cam boots:

/etc/init.d $ cat S98tinyftp
#!/bin/sh
/bin/tinyftp -d -c /bin/vs/sd &

That's all. I hope you enjoy.

Ps: I still want to know how to fix the mime type issue (for the email). If someone has a solution, please answer
