LLVM Developers Are Still Debating How To Handle The Intel JCC Erratum Mitigation

Phoronix - Wed, 03/25/2020 - 16:34
Disclosed back in mid-November was the Intel JCC Erratum that required a CPU microcode update to mitigate and that in turn had broad performance hits. But via toolchain updates, some of that overhead can be offset. The GNU Assembler patches were quickly merged and new options exposed for helping to decrease that performance hit but on the LLVM side the developers are still working on their mitigation with some design decisions still to be made...

In Kubernetes, objects are analogous to a job or a completed task in the real world. You can use them to define common tasks, store them in a version control system, and apply them with kubectl apply. Kubernetes ensures that this triggers everything necessary to bring your declarative description to life by creating the depending resources (like pods) to run your software. Kubernetes contains a number of built-in object types that can be created with this workflow, like Deployments and Services.

Getting started with hidden Markov models using Perl

opensource.com - Wed, 03/25/2020 - 15:01

A Markov model (named after the mathematician Andrey Markov) is used for forecasting in systems of random change. Markov's insight is that good predictions in this context can be made from only the most recent occurrence of an event, ignoring any occurrences before the current one. The approach might be described as memoryless or history-agnostic prediction.
