Intel and Microsoft have insisted that the performance impact of the Kernel Page Table Isolation fix for the recently-revealed Meltdown vulnerability will be much smaller than people feared. Cavium and ARM rival Qualcomm work together to reduce the amount of software that has to be rewritten for ARM chips.

Update related to the security of the operating system, and was to close a vulnerability Meltdown and the Specter.

Scaleway, OVH, Linode, Packet, Digital Ocean, Vultr, Nexcess, and prgmr.com have been part of it, later joined by Amazon, Tata Communications, and also parts of the RedHat and Ubuntu teams.

Other news announced during Krzanich's keynote include the launch of Intel Studios for advanced, 3D video productions; support for Intel-powered virtual reality broadcasts during the coming Olympic Winter Games; and autonomous driving technology partnerships with BMW, Nissan, Volkswagen, SAIC Motor, NavInfo, and Ferrari North America.

Google researchers last year discovered that features, present in almost all processors running computers and phones, could give cyberattackers unauthorized access to sensitive data. Just before Krzanich took the stage to address the members of the press, we witnessed quite a spectacle where musicians played on 'invisible' instruments, using special smart gloves and Intel's camera to capture the precise movement of the musician's hand gestures and finger movements to generate the desired musical notes.

Microsoft gave a more pessimistic appraisal than Intel's initial assessments, particularly for servers that form the backbone of corporate networks.

Intel CPUs can be exploited by hackers. We will then focus on issuing updates for older products as prioritized by our customers. Their statement is published on their blog at www.amd.com/speculative_execution and you can read it below.

"At least Intel and others have been able to respond in a reasonably efficient manner". Transparent and timely sharing of performance data by hardware and software developers is essential to rapid progress. "If the fix for x86 results in a dramatically decreased level of performance, that might increasingly push in favor of switching to ARM".

Security researchers found two separate problems that would put devices at risk in different ways.

CEO Brian Krzanich has promised more transparency from Intel in a seperate post, saying it would publicly disclose significant vulnerabilities and add funding for "academic and independent research into potential security threats", as well as consistent progress reports for all issued and forthcoming patches. Data is the big talking point for Intel but it's what the company plans to do (or wants to do) was the most interesting bit of Monday's keynote. LinkedIn is owned by Microsoft. The Motley Fool owns shares of and recommends Alphabet (A and C shares) and Apple. By the end of the month, Intel plans to issue software updates for the remainder 10% of processors introduced in the same period. The Motley Fool has a disclosure policy.
