Meltdown and Spectre: CPU Security Vulnerabilities

In this blog post, we examine the recent revelations about CPU security vulnerabilities.

The beginning of the new year also brings to light fresh and new CPU security vulnerabilities. Today’s big offenders originate on the hardware side – more specifically, the CPU. The reported hardware kernel bugs allow for direct access to data held in the computer/server’s memory, which in turn might leak sensitive data. Some of the most popular CPUs affected by these bugs are Intel, AMD and ARM.

The most important thing to know is that this vulnerability is not exploitable remotely, and requires that someone execute the malicious code locally. However, take extra precaution when running in virtualized environments (see below for more information).

A full overview (including a technical, in-depth …

Premier Open Source Database Conference Call for Papers closing January 12 2018

The call for papers for Percona Live Santa Clara 2018 was extended till January 12 2018. This means you still have time to get a submission in.

Topics of interest: MySQL, MongoDB, PostgreSQL & other open source databases. Don’t forget all the upcoming databases too (there’s a long list at db-engines).

I think to be fair, in the catch all “other”, we should also be thinking a lot about things like containerisation (Docker), Kubernetes, Mesosphere, the cloud (Amazon AWS RDS, Microsoft Azure, Google Cloud SQL, etc.), analytics …

This Week in Data with Colin Charles 20: cPanel changes strategy, Percona Live CFP extended

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

I think the biggest news from last week was from cPanel – if you haven’t already read the post, please do – on Being a Good Open Source Community Member: Why we hesitated on MySQL 5.7. cPanel anticipated MariaDB being the eventual replacement for MySQL, based on movements from Red Hat, Wikipedia and Google. The advantage focused on transparency around security disclosure, and the added features/improvements. Today though, “MySQL now consistently matches or outpaces MariaDB when it comes to development and releases, which in turn is increasing the demand on us for providing those upgraded versions of MySQL by our users.” And …

Three P’s of a Successful Black Friday: Percona, Pepper Media Holding, and PMM

As we close out the holiday season, let’s look at some data that tells us how to guarantee a successful Black Friday (from a database perspective).
