There's been a lot of leaks and rumours about the new NVIDIA GPUs over the last few weeks, but we should finally have the facts soon. NVIDIA have a twitch stream running which will apparently be making the official announcement in under 6 hours from now. Plenty of discussion in this thread in our Video Cards forum.

An Australian teen is in hot water after apparently hacking Apple. The story became more interesting when it was found that he saved all the instructions for hacking and the hacked data in a folder named “hacky hack hack.” The hacker in question has pleaded guilty in the court, and the magistrate has decided to announce the sentence by next week because of the complexities involved in the case.

Google are using AI to cool datacentres. Now, Google says, it has effectively handed control to the algorithm, which is managing cooling at several of its data centers all by itself. “It’s the first time that an autonomous industrial control system will be deployed at this scale, to the best of our knowledge,” says Mustafa Suleyman, head of applied AI at DeepMind, the London-based artificial-intelligence company Google acquired in 2014.

If the crypto-fuelled price rises on GPUs have annoyed you, NVIDIA may have good news - that they expect to no longer make any money from that market. Although Nvidia’s report said the company was expecting a decline in GPU sales and “cryptocurrency-specific products” from a peak of $289 million last quarter to about $100 million this quarter, the actual revenue for its crypto-specific products ended up being a mere $18 million. That’s a 93 percent decrease in just three months. “Whereas we had previously anticipated cryptocurrency to be meaningful for the year, we are now projecting no contributions going forward,” Nvidia’s report reads. Personally I dabbled a bit in Nicehash but stopped a few months ago.

ARM have revealed a new CPU roadmap, showing plans to tackle AMD and Intel in the mobile market. We have been given a roadmap of the next two generations of products from the company that are intended to compete in not only the cellphone market, but also in the laptop market. ARM has thrown down the gauntlet and their sights are set on Intel and AMD. Not only is ARM showing us the codenames for these products, but also the relative performance.

Techgage report from SIGGRAPH 2018 in Vancouver. SIGGRAPH is the place to be if your job revolves around graphics technology. You not only get to see the latest graphics tech up close, you also get to peer into the future. You of course also get to refine your craft by keeping-up on cutting-edge technologies and techniques.

Meanwhile, GamingNexus sent a self-described "clueless noob" to the Call of Duty World Championship. From what I have gleaned listening to my son play online matches, Call of Duty fans are A) an average of fifteen years old, B) insanely cruel, and C) super racist. I am hoping to have the opportunity to drop the dad hammer on some rabid pipsqueaks that I overhear being mean to each other, safe in the knowledge that I can use my press pass to scurry away to safety if they turn on me.

SiliconAngel sent word of a remote Spectre attack. Honestly it's hard to keep track of these things lately. Until now, Spectre attacks have required malicious code to be running on a vulnerable machine to potentially extract passwords, keys, and other secrets, from the memory of other software on the computer. Now, here comes NetSpectre: a technique for potentially extracting private information from another device on the network without requiring any exploit code on the target box, albeit exfiltrating it rather slowly. There are potentially billions of computers, gadgets, and gizmos at some degree of risk.

Yet another Intel CPU vulnerability has been uncovered - this time it's called Foreshadow. The researchers reported these findings to Intel earlier this year, and the company’s own analysis into the causes of the vulnerability led to the discovery of a new variant of Foreshadow, called Foreshadow-NG. This particular variant is theoretically capable of bypassing the earlier fixes introduced to protect computers against Meltdown and Spectre — potentially re-exposing millions of computers globally to attacks. Intel has since release patches and updates to mitigate all varients of Foreshadow. However, more research will need to be done to understand the full impact of the Foreshadow-NG variant. More info here on Redhat, and there's a Windows 10 patch already. Discussion here.

NVIDIA have unveiled their new next-gen Turing GPU architecture at SIGGRAPH 2018. The next generation of NVIDIA’s GPU designs, Turing will be incorporating a number of new features and is rolling out this year. While the focus of today’s announcements is on the professional visualization (ProViz) side of matters, we expect to see this used in other upcoming NVIDIA products as well. And by the same token, today’s reveal should not be considered an exhaustive listing of all of Turing’s features.

There's a bit of an uproar about Google storing location data, even if you turn that feature off. Google says that will prevent the company from remembering where you’ve been. Google’s support page on the subject states: “You can turn off Location History at any time. With Location History off, the places you go are no longer stored.” That isn’t true. Even with Location History paused, some Google apps automatically store time-stamped location data without asking. (It’s possible, although laborious, to delete it.)

The Government have provided info on how they plan to target encryption. “The Australian government has no interest in undermining systems that protect the fundamental security of communications,” it said. However, the government plans to compel a range of companies that make up end-to-end communications services "to enable access to a particular service, particular device or particular item of software". The targeted provider must come up with a method "which would not systemically weaken these products across the market." So a magic backdoor that can only be exploited by the good guys. What could possibly go wrong?
