Twitter officially disabled Basic authentication this week, the final step in the company’s transition to mandatory OAuth authentication. Sadly, Twitter’s extremely poor implementation of the OAuth standard offers a textbook example of how to do it wrong. This article will explore some of the problems with Twitter’s OAuth implementation and some potential pitfalls inherent to the standard. I will also show you how I managed to compromise the secret OAuth key in Twitter’s very own official client application for Android.

OAuth is an emerging authentication standard that is being adopted by a growing number of social networking services. It defines a key exchange mechanism that allows users to grant a third-party application access to their account without having to provide that application with their credentials. It also allows users to selectively revoke an application’s access to their account.

By now, we’ve learned the Japanese have found a number of creative ways to use the iPad. And today we can show you a new one: the iPad as the basis of a sophisticated, yet low-cost point of sale cash register system. Dubbed FLAVIUS [JP], the system is actually being used by several business across Japan already.

The way it works is that the iPad is the core of a system that also includes a special-purpose counter (pictured below) and a Wi-Fi router. The iPad can be used as both a cash register interface and as an ordering device. FLAVIUS maker Global Network service even integrated a reporting and attendance management system into the system.

For example, it’s possible for owners to check the revenues of their stores remotely (on the web) and in real-time.

Back in February of 2009, the launch of Sony’s LocationPorter RVT-SD100 suggest that the days of needing a tricked out news van to transmit real-time on the scene video could be a thing of the past — that is, if you had a spare $18k lying around and a solid 3G data connection. The newly-announced RVT-SD200 and its companion RVT-MR200 expands upon that dream by enabling up to 12 LocationPorters to transmit images to one single receiver. Besides paving the way for armies of techno box-toting reporters — like the one pictured above — to relay news as it happens, Sony also sees the potential for emergency services like police forces and fire departments to make use of the equipment to relay critical information. We could see that too, but if this new system is priced at anything like the old, we’re betting tight public budgets won’t make it happen. Then again we can’t speak for the Sultan of Brunei’s security force.

Logitech has a history of pumping out better-than-average PC speakers at below-average prices, and the outfit’s at it once more with the Z623 system. This simplistic setup is a 2.1 rig, complete with a pair of mobile satellites and a ported subwoofer. Logi’s marketing this as the perfect setup for PC users and bedroom home theaters, and it’s including RCA / 3.5mm input sockets along with an inbuilt headphone jack. All told, you’re getting 200 watts (RMS) of power, and we’re guessing that prominent THX logo factors into the $149.99 asking price. If that’s still lower than you were expecting, you can fetch these for your own flat this September in the US and Europe. Oh, and there’s a promo video just past the break… you know, if you’re into that type of thing.
