David Patterson Says It’s Time for New Computer Architectures and Software Languages
Moore’s Law officially Dead in terms of clock speeds.

David Patterson, University of California professor, Google engineer, and RISC pioneer, says there’s no better time than now to be a computer architect.

That’s because Moore’s Law really is over, he says: “We are now a factor of 15 behind where we should be if Moore’s Law were still operative. We are in the post-Moore’s Law era.”

Time-travelling exploits with Meltdown – Pwn All The Things – Medium
"This past week there’s been a lot of speculation over two new processor vulnerabilities called Meltdown and Spectre. In this post I’ll talk about Meltdown. I’ll talk about Spectre elsewhere later."

C Is Not a Low-level Language - ACM Queue
"In the wake of the recent Meltdown and Spectre vulnerabilities, it's worth spending some time looking at root causes. Both of these vulnerabilities involved processors speculatively executing instructions past some kind of access check and allowing the attacker to observe the results via a side channel. The features that led to these vulnerabilities, along with several others, were added to let C programmers continue to believe they were programming in a low-level language, when this hasn't been the case for decades."

Benchmark | Corona Renderer
The benchmark runs using Corona Renderer 1.3, which is an older version of Corona Renderer – updating the benchmark to a newer version of Corona Renderer would have no impact on the relative performance of 2 different CPUs and would only invalidate all the results gathered so far, so staying with the older version is actually useful from the point of view of a benchmark application. For using Corona Renderer as a render engine, naturally the newer (and faster) versions are better!

Installation and Use
It’s easy to use: save, extract, and run the file. Benchmark starts to render the testing scene automatically and shows the result at the end, with an option to submit the result to this page. You can also copy it to the benchmark forum thread.

Despite 'Painful' Spectre Response, Linus Torvalds Says He Still Loves Speculative Execution - Slashdot
At this year's Open Source Summit, Linus Torvalds sat for a wide-ranging "keynote" interview with Dirk Hohndel, chief open source officer at VMWare, which has been partially transcribed below. And Linus explained, among other things, why the last merge window was harder than others:
