I'm on verizon and so are most of my friends so I'm not switching to another company just yet when I get 90% of my calls and text messages for free. That said I'm looking forward to the Blackberry Storm in the mean time and hope Verizon comes out with an Android phone later.

Web Server On a Business Card 169

Posted by kdawson on Friday September 26, 2008 @10:01AM from the at-your-service dept.

mollyhackit writes "We've seen tiny Web servers in the past, but rarely ones that are home-built. Here's a guide to building your own tiny web server with a footprint no larger than a business card. The design uses two major chips. One handles the SPI to MAC/PHY translation for the ethernet jack. The other chip is a PIC24F, which hosts a simple web server and reads files stored on a microSD card. All components run at a low 3.3 volts. Part of the compactness of the design comes from the PIC24F having programmable pins; only four jumper wires were needed. The single-sided SMD design is easy to manufacture at home. Part 1 covered many of the 24F's features and both posts have full code available."

How Facebook Stores Billions of Photos 154

David Gobaud writes "Jason Sobel, the manager of infrastructure engineering at Facebook, gave an interesting presentation titled Needle in a Haystack: Efficient Storage of Billions of Photos at Stanford for the Stanford ACM. Jason explains how Facebook efficiently stores ~6.5 billion images, in 4 or 5 sizes each, totaling ~30 billion files, and a total of 540 TB and serving 475,000 images per second at peak. The presentation is now online here in the form of a Flowgram."

When Is a Self-Signed SSL Certificate Acceptable? 627

Posted by kdawson on Wednesday June 25, 2008 @05:53AM from the how-about-never-is-never-good-for-you dept.

UltraLoser writes "When is it acceptable to encourage users to accept a self-signed SSL cert? Recently the staff of a certain Web site turned on optional SSL with a self-signed and domain-mismatched certificate for its users and encourages them to add an exception for this certificate. Their defense is that it is just as secure as one signed by a commercial CA; and because their site exists for the distribution of copyrighted material the staff do not want to have their personal information in the hands of a CA. In their situation is it acceptable to encourage users to trust this certificate or is this giving users a false sense of security?"

Two Trojans For Mac OS X 326

Posted by kdawson on Wednesday June 25, 2008 @03:31AM from the knock-knock-who's-there-trojan dept.

I Don't Believe in Imaginary Property writes "F-Secure is reporting that there are two new Mac OS X trojans. The first is just a proof-of-concept from the MacShadows people that takes advantage of the unpatched ARDAgent vulnerability to get root access when run by the user. The second relies on social engineering: it's a poker game that requests the user's password, claiming to have detected a 'corrupt preference file.' It then takes control of the computer. Now that the source of the proof-of-concept is publicly available, we can expect that future trojans won't just politely request your password."
