HotHardware built a liquid-cooled Ryzen 9 3900X PC with the help of boutique PC builder (which is apparently a thing) Maingear. Of course, historically, to own a Maingear-built PC meant as an end user you actually had to buy a pre-built machine, rather than building your own, that is at least until very recently. Earlier this year, Maingear debuted its Vybe PC chassis with Apex Liquid Cooling solution specifically for the DIY PC builder market.

A recent infrastructure audit has concluded that some NBN users will face higher prices or lower-quality service in future. The government-owned NBN Co is required to achieve a 3.2 per cent return on investment to remain an off-budget asset rather than a liability, leading to "an inherent tension between the NBN's strategic goals," the infrastructure advisory body warned, saying it would potentially have to trade-off user outcomes to deliver the return.

Ransomware on PCs is unfortunately nothing new nowadays, but apparently now some DSLR cameras are at risk. Check Point Software Technologies issued a report today that detailed how its security researchers were able to remotely install malware on a digital DSLR camera. In it, researcher Eyal Itkin found that a hacker can easily plant malware on a digital camera. He says that the standardized Picture Transfer Protocol is an ideal method for delivering malware: itís unauthenticated and can be used with both Wi-Fi and USB. The report notes that individual with an infected Wi-Fi access point could deploy it at a tourist destination to pull off an attack, or infect a userís PC. Discussion here.

Phoronix looked into the performance effects of the recent SWAPGS vulnerability patches. Especially with that text, I was quite interested in seeing what the performance is looking like as a result of this latest kernel activity for tightening up the Intel CPU security. This morning I have results wrapped up on an Intel Core i9 9900K processor. SWAPGS or the "Grand Schemozzle" is believed to affect all Intel CPUs from at least Ivybridge through their latest products.

The USA's Department of Defence has ordered three new Cray supercomputers. The ARL system will be comprised of 102,400 Epyc Rome compute cores plus 292 Nvidia Volta V100 GPUs. Storage will be supplied by 350 TB of NVM-Express flash, backed by 11 PB of disk storage. The ERDC machine is computationally less intense, with 80,320 Epyc cores and just 16 V100 GPUs. Storage is distributed a little differently as well, with 30 TB of NVM-Express flash and 15 PB of disk capacity. Together, the two CS500 systems provide 10.6 petaflops of peak performance, which will bump the aggregate capacity of the HPCMP supercomputing to 57 petaflops.
