Back on broadband! Not that I really missed it or anything. *twitch*

Tony and mpot sent word that Telstra payphones are going to become Wifi hotspots. This will form part of the $100 million Wi-Fi hotspot network Telstra announced in May. The company will build 8000 of its own hotspots while partnering with retail stores and local governments to get 2 million hotspots around the country over five years. After the trial period, the Wi-Fi hotspots will only be free for Telstra fixed-line internet customers with others paying a fee to use it.

Tech Report cover NVIDIA's Dynamic Super Resolution. One of the more intriguing capabilities Nvidia introduced with the GeForce GTX 970 and 980 is a feature called Dynamic Super Resolution, or DSR, for short. Nvidia bills it as a means of getting 4K quality on a 2K display. How good is it? We take a look.

They also have some more info on Windows 10 which was announced this morning. Yes, the next version of Windows is called Windows 10—and Microsoft gave the first public demo of it at a press event this morning. The company also announced the Windows Insider Program, as part of which folks will be able to grab a Technical Preview build of the new OS starting tomorrow. This time, it isn't an April Fools. :)

Here's an interesting one from AirQ, about mining Bitcoin with pencil and paper. I decided to see how practical it would be to mine Bitcoin with pencil and paper. It turns out that the SHA-256 algorithm used for mining is pretty simple and can in fact be done by hand. Not surprisingly, the process is extremely slow compared to hardware mining and is entirely impractical. But performing the algorithm manually is a good way to understand exactly how it works.

Australian startup Euclideon have hit the headlines again with their voxel rendering tech. Perhaps the most surprising aspect of Euclideon's technology is that, for now, it runs only on the CPU. Dell said the current implementation produces 2000x1000 frames at around 32 FPS on a six-core processor. He claims there's "no reason" the technology can't be sped up using, for instance, OpenCL on a GPU, but there are "lots of software ways" to improve performance yet. Jumping straight to GPU optimization would be "admitting defeat," in his view.

Techgage are overclocking the GeForce 970 and 980. We’ve established that NVIDIA’s Maxwell-based graphics cards are impressive, but can they continue to impress when it comes to overclocking? As it turns out, yes – yes they can. Given their ability to push clocks far beyond stock, we’ve even decided to take up a challenge: Can an overclocked GTX 970 match a stock GTX 980? HardOCP had a pretty good go at it too.

SiliconAngel posted an article in the forums about rebadged flash cards. As I'm sure you know, there’s a lot of rebadging and fakery in the CF card market. What I didn’t personally realise was some scammers aren’t using cards with insufficient capacity or just heavily damaged, some of them are using quite good cards that they’re rebadging as premium range ones.

Microsoft have announced they are skipping Windows 9 and going straight to Windows 10. It’s time for a new Windows. This new Windows must be built from the ground-up for a mobile-first, cloud-first world. This new Windows must help our customers be productive in both their digital work and their digital life. This new Windows must empower people and organizations to do great things.

Discussion in this thread.
